ITEM 4. DESCRIPTION OF SECURITIES.

      This registration statement covers (i) shares of the Registrant's Common
Stock that have been registered under Section 12 of the Exchange Act, (ii)
deferred compensation obligations that may be issued under the Regions Financial
Corporation Supplemental 401(k) Plan (the "Regions DCO Plan") and the Union
Planters Corporation Amended and Restated 1996 Deferred Compensation Plan for
Executives (the "Union Planters DCO Plan," and collectively, with the Regions
DCO Plan, the "Deferred Compensation Plans"), and (iii) and an indeterminate
amount of plan interests to be offered or sold pursuant to the Regions Financial
Corporation 401(k) Plan and the Union Planters Corporation 401(k) Retirement
Savings Plan.

      The following summary of the deferred compensation obligations ("DCOs")
that may be issued under the Deferred Compensation Plans is qualified in its
entirety by reference to the Deferred Compensation Plans, which are included as
exhibits to this registration statement.

      The DCOs represent obligations of the Registrant to pay to participants
certain compensation amounts that the participants have elected to defer. The
Deferred Compensation Plans are intended to allow certain highly compensated
employees to defer the payment of current compensation to future years for tax
and financial planning purposes. The DCOs under the Regions DCO Plan are payable
in cash and generally will be paid in either a lump-sum or in annual
installments over a certain term upon retirement, death, or other termination of
service. The DCOs under the Union Planters DCO Plan are payable in cash in a
lump-sum upon retirement, death, or other termination of service. Participants
in the Union Planters DCO Plan may also elect to receive some or all of the
deferred amounts and related earnings pursuant to an in-service distribution.

      Subject to the terms and conditions set forth in the Regions DCO Plan,
each participating employee may elect to defer eligible compensation, and
amounts deferred are credited to each participant's account. Amounts in a
participant's account will be indexed to one or more investment alternatives
chosen by each participant from a range of such alternatives available under the
Regions DCO Plan, including a Registrant Common Stock fund. Each participant's
account will be adjusted to reflect the investment performance of the selected
investment fund(s), including any appreciation or depreciation.

      Subject to the terms and conditions set forth in the Union Planters DCO
Plan, each participating employee may elect to defer eligible compensation, and
amounts deferred are credited to each participant's account, which is maintained
as a "cash account" and a parallel phantom "stock account."


                                      II-2

Interest on amounts in a participant's cash account will be credited each month
based on the applicable federal rate (which is 120% of the applicable federal
rate pursuant to Section 1274(d) of the Internal Revenue Code of 1986, as
amended). The participant's stock account will be indexed to a Registrant Common
Stock fund and will be adjusted to reflect the investment performance of the
Registrant's Common Stock, including any appreciation or depreciation. Upon
distribution of a participant's account, the participant will receive the
greater of the value of his or her cash account and his or her stock account.

      Under both of the Deferred Compensation Plans, the obligation to pay the
balance of each participant's account shall at all times be an unfunded and
unsecured obligation of the Registrant. Benefits are payable solely from the
Registrant's general funds and are subject to the risk of corporate insolvency.
Participants will not have any interest in any particular assets of the
Registrant by reason of any obligation created under the Deferred Compensation
Plans. A participant's right to the DCOs cannot be transferred assigned, pledged
or encumbered except by a written designation of a beneficiary under the terms
of the Deferred Compensation Plans.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

      Not Applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

      The Registrant's certificate of incorporation provides that the Registrant
shall indemnify its directors and officers to the fullest extent permitted by
the Delaware General Corporation Law (the "DGCL").

      In addition, the Registrant's certificate of incorporation provides that
no director shall be personally liable to the Registrant or its stockholders for
monetary damages arising out of a breach of fiduciary duty, except for:

            -     any breach of the director's duty of loyalty to the Registrant
                  or its stockholders,

            -     acts or omissions not in good faith or which involve
                  intentional misconduct or a knowing violation of law,

            -     breaches under Section 174 of the DGCL, or

            -     any transaction from which the director derived an improper
                  personal benefit.

      Section 145 of the DGCL provides that, subject to certain limitations in
the case of suits brought by a corporation and derivative suits brought by a
corporation's stockholders in its name, a corporation may indemnify any person
who is made a party to any suit or proceeding by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation
against expenses, including attorney's fees, judgments, fines and amounts paid
in settlement reasonably incurred by him in connection with the action, through,
among other things, a majority vote of the directors who were not parties to the
suit or proceeding, if the person (1) acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and (2) in a criminal proceeding, had no reasonable cause to
believe his conduct was unlawful.

      Section 145(b) of the DGCL provides that no such indemnification of
directors, officers, employees or agents may be made in respect of any claim,
issue or matter as to which such person shall have been adjudged to be liable to
the corporation, unless and only to the extent that the Court of


                                      II-3

Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

      Not Applicable.

      In lieu of the opinion of counsel or determination letter contemplated by

ITEM 9. UNDERTAKINGS.

      (a) The undersigned Registrant hereby undertakes:

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


                                      II-4

            (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 this 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 this Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in this registration statement;

            (iii) To include any material information with respect to the plan
of distribution not previously disclosed in this Registration Statement or any
material change to such information in this 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 this
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 being 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 Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
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 Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
