                           PURPOSE OF THIS PROSPECTUS


                  The purpose of this prospectus is to register shares of common
stock of SouthTrust Corporation beneficially owned by the selling stockholders
to enable the selling stockholders to resell their shares.

                  Pursuant to an Agreement and Plan of Merger, dated July 14,
1998, as amended, among, SecurityBank Texas, and SouthTrust Corporation and
certain of its affiliates, SecurityBank Texas was merged with and into
SouthTrust Bank, N.A., an affiliate and subsidiary of SouthTrust Corporation.
The shareholders of SecurityBank Texas received, in exchange for their shares of
common stock of SecurityBank Texas, the shares of common stock of SouthTrust
Corporation being offered by this prospectus.

                  Under the Agreement and Plan of Merger, we agreed to register
the shares of common stock of SouthTrust Corporation issued to the shareholders
of SecurityBank Texas in connection with the merger and to use our best efforts
to keep the registration statement effective for a period of two years
thereafter to permit any potential resale of the shares of common stock of
SouthTrust Corporation by the shareholders of SecurityBank Texas to occur.


                            THE SELLING STOCKHOLDERS

                  The following list of selling stockholders includes the
stockholders of SecurityBank who received shares of common stock of SouthTrust
Corporation as a result of the merger of SecurityBank Texas with and into
SouthTrust Bank, N.A. and other stockholders who are expected to receive such
shares from the shareholders of SecurityBank directly pursuant to agreements
between the shareholders of SecurityBank and such selling stockholder and
indirectly pursuant to the assignment to such selling stockholder of the right
to receive such shares.

                  The shares of common stock of SouthTrust Corporation listed
below represent all of the shares that each selling stockholder currently owns,
or which each selling stockholder may own upon the transfer of shares of common
stock of SouthTrust Corporation to such selling stockholder from the
shareholders of SecurityBank.

                  None of the selling stockholders have acquired one percent or
more of the total number of shares of common stock of SouthTrust Corporation
which are outstanding. Certain of the selling stockholders, their associates and
affiliates may from time to time be customers of, engage in transactions with,
or perform services for, SouthTrust Corporation, its affiliated banks and other
subsidiaries of SouthTrust Corporation in the ordinary course of business.


                                 USE OF PROCEEDS

                  All net proceeds from the sale of these shares will go to the
selling stockholders who are offering and selling their shares of common stock
of SouthTrust Corporation. Accordingly, SouthTrust Corporation will not receive
any proceeds from the sale of these shares.


                              PLAN OF DISTRIBUTION

                  The sale of the shares offered hereby by the selling
stockholders may be effected from time to time in transactions (which may
include block transactions) in the over-the-counter market, in negotiated
transactions, or through a combination of such methods of sale, at fixed prices
which may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices, or at negotiated prices. The selling
stockholders may effect such transactions by selling shares to or through
broker-dealers, and such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the selling stockholders and/or the
purchasers of shares for whom such broker-dealers may act as agent or to whom
they may sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

                  SouthTrust Corporation is paying all of the expenses of
registering the shares offered hereby under the Securities Act of 1933 (other
than selling discounts, commissions, fees and expenses of counsel and other
advisors to the selling stockholders), including filing, printing, legal,
accounting and miscellaneous expenses in connection with this offering.

ITEM 15.          INDEMNIFICATION OF OFFICERS AND DIRECTORS

                  The Restated Certificate of Incorporation and the Bylaws of
SouthTrust provide that SouthTrust shall indemnify its officers, directors,
employees, and agents to the extent permitted by the General Corporation Law of
the State of Delaware, which permits a corporation to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding by reason of the fact that he is or was
a director, officer, employee, or agent of SouthTrust, against expenses
(including attorney's fees), judgments, fines, and settlements incurred by him
in connection with any such suit or proceeding, if he acted in good faith and in
a manner reasonably believed to be in or not opposed to the best interests of
SouthTrust. In the case of a derivative action on behalf of SouthTrust,
SouthTrust shall indemnify such persons only against expenses and then only if
he is not or has not been adjudged to be liable for negligence or misconduct.
SouthTrust also maintains insurance coverage relating to certain liabilities of
officers and directors.

ITEM 17.          UNDERTAKINGS

                  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:

                                    (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;

                                    (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 the registration
                                            statement;

provided, however, that paragraphs (1)(i) and (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 offered herein,
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 post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

                  The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                  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.

Merger (as defined below)). The Merger shall become effective on the date and
at the time on which the Merger is deemed effective by the Department of
Banking of the State of Texas (the "Department") (such time is hereinafter

its place. Neither the rights of creditors nor any liens upon the property of
any constituent corporation shall be impaired by the Merger.

                                   ARTICLE II

                   CONVERSION OF CONSTITUENTS' CAPITAL SHARES


         Section 2.1       Manner of Conversion of the Bank Shares. Subject to 
the provisions hereof, as of the Effective Time of the Merger and by virtue of
the Merger and without any further action on the part of SouthTrust, ST-Sub,
ST-Bank or the Bank or any of their shareholders, the shares of the constituent
corporations shall be converted as set forth below:

         (a)      Each share of common stock of the Bank (the "Bank Shares") and
each share of common stock of ST-Bank (the "ST-Bank Shares") held by the Bank,
SouthTrust or ST-Sub (or any of their subsidiaries), other than in a fiduciary
capacity or as a result of debts previously contracted, shall be canceled and
retired and no consideration shall be paid or delivered in exchange therefor.

         (b)      Subject to the terms and conditions of this Agreement, 
including, without limitation, Section 2.3 of this Agreement and except with
regard to Dissenting Shares (as defined in Section 2.1(d) of this Agreement)
and the Bank Shares excluded in (a) above, each Bank Share outstanding
immediately prior to the Effective Time of the Merger shall be converted into
the right to receive the quotient of (i) the Merger Consideration (as defined
below) divided by (ii) the number of Bank Shares outstanding immediately prior
to the Effective Time of the Merger (hereinafter referred to as the "Conversion
Ratio").


                                       4
<PAGE>   13

                  For purposes of this Agreement, the term "Merger
Consideration" shall mean the number of shares of common stock of SouthTrust
(and the rights associated therewith pursuant to a Rights Agreement, dated
February 22, 1989 between SouthTrust and Mellon Bank, N.A.) (together, the
"SouthTrust Shares") equal to the quotient of (i) $30,000,000 divided by (ii)
the Average Closing Price; provided that (A) if the quotient is less than
695,675, the Merger Consideration shall be 695,675 SouthTrust Shares, and (B)
if the quotient is more than 785,675, then SouthTrust may, at its written
election, refuse to increase the Merger Consideration to more than 785,675
SouthTrust Shares, provided that the Bank may elect to terminate this Agreement
within three (3) business days after such written election.

                  For purposes of this Agreement, the term "Average Closing
Price" shall mean the average of the daily last sales prices of SouthTrust
Shares reported on the NasDaq- National Market System ("NASDAQ/NMS") (as
reported by The Wall Street Journal or, if not reported thereby, another
authoritative source as chosen by SouthTrust) for the twenty (20) consecutive
full trading days in which such shares are traded on the NASDAQ/NMS ending at
the close of trading on the tenth (10th) business day prior to the Effective
Time of the Merger.

                  Further, if the Effective Time of the Merger does not occur
on or before the record date for the payment of the regular quarterly dividend
on the SouthTrust Shares declared during the fourth quarter of fiscal year
1998, then, notwithstanding the foregoing, the number of SouthTrust Shares
included in the Merger Consideration shall be increased by adding thereto the
quotient of (A) the amount of such quarterly dividend divided by (B) the
Average Closing Price.

         (c)      Subject to the terms and upon the conditions of this 
Agreement, including, without limitation, Section 2.2 of this Agreement and the
ST-Bank Shares excluded in (a) above, each ST-Bank Share outstanding
immediately prior to the Effective Time of the Merger shall be converted into
one fully paid and non-assessable share of Common Stock of the Surviving
Corporation and shall constitute all of the issued and outstanding shares of
capital stock of the Surviving Corporation.

         (d)      Each outstanding Bank Share, the holder of which has demanded
and perfected such holder's demand for payment of the fair value of such share
in accordance with Section 5.12 of the Texas Business Corporation Act (the
"Dissent Provisions"), and has not effectively withdrawn or lost such holder's
right to such appraisal (the "Dissenting Shares"), shall not be converted into
or represent a right to receive the SouthTrust Shares issuable in the Merger
but the holder thereof shall be entitled only to such rights as are granted by
the Dissent Provisions. The Bank shall give SouthTrust prompt notice upon
receipt by the Bank of any written objection to the Merger and any written
demand for payment of the fair value of any Bank Shares and of withdrawals of
such demands, and any other instrument provided to the Bank pursuant to the
Dissent Provisions (any shareholder duly making such demand being hereinafter
called a "Dissenting Shareholder"). Each Dissenting Shareholder who becomes
entitled, pursuant to the Dissent Provisions, to payment of fair value for any
Bank Share held by such Dissenting Shareholder shall receive payment therefor
from the Surviving Corporation, as escrow agent (the "Escrow Agent"), on behalf
of the Bank, as the case may be, out of funds provided to the Escrow Agent by
the Bank, as the case may be, in accordance with the provisions of Section
2.1(e) and the Dissent Provisions and all of the Bank Shares held by such
Dissenting Shareholder shall be canceled. Neither the Bank nor the Surviving
Corporation shall, except with the prior written consent of SouthTrust,
voluntarily make any payment with


                                       5
<PAGE>   14

respect to, or settle or offer to settle, any demand for payment by any
Dissenting Shareholder. If any Dissenting Shareholder shall have failed to
perfect or shall have effectively withdrawn or lost such right to demand
payment of fair value, the Bank Shares held by such Dissenting Shareholder
shall thereupon be deemed to have been converted into the right to receive the
consideration to be issued in the Merger as provided by this Agreement.

         (e)      With respect to each Dissenting Shareholder, on or immediately
prior to the Effective Time of the Merger, the Bank shall deposit with the
Escrow Agent an amount in cash equal to 150% of the consideration (with the
SouthTrust Shares being valued in the manner set forth in Section 2.3) such
Dissenting Shareholder would have received in the Merger, but for the exercise
of the Dissent Provisions (the "Dissent Escrow"). The Escrow Agent shall
disburse the Dissent Escrow to such Dissenting Shareholders in accordance with
the Dissent Provisions. Any and all funds remaining in the Dissent Escrow after
such disbursement shall be remitted to the Surviving Corporation.

         Section 2.2       Fractional Shares. Notwithstanding any other 
provision of this Agreement, each holder of Bank Shares converted pursuant to
the Merger, and each holder of Bank Options assumed by SouthTrust pursuant to
this Agreement, who would otherwise have been entitled to receive a fraction of
a SouthTrust Share (after taking into account all certificates delivered by
such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of such SouthTrust Share, multiplied by
the market value of one SouthTrust Share at the Effective Time of the Merger.
The market value of one SouthTrust Share at the Effective Time of the Merger,
shall be the last sale price of such SouthTrust Shares, as reported by
NASDAQ/NMS on the last business day preceding the Effective Time of the Merger
or, if the SouthTrust Shares hereafter become listed for trading on any
national securities exchange registered under the Exchange Act, the last sale
price of such SouthTrust Shares on the applicable date as reported on the
principal securities exchange on which the SouthTrust Shares are then listed
for trading. No such holder will be entitled to dividends, voting rights or any
other rights as a shareholder in respect of any fractional share.

         Section 2.3       Effectuating Conversion. (a) SouthTrust shall
designate such institution as it may select, including SouthTrust or one of its
affiliates, to serve as the exchange agent (the "Exchange Agent") pursuant to
this Agreement. The Exchange Agent may employ sub-agents in connection with
performing its duties. As of the Effective Time of the Merger, SouthTrust will
deliver or cause to be delivered to the Exchange Agent the consideration to be
paid by SouthTrust for the Bank Shares, along with an appropriate cash payment
in lieu of fractional interests in SouthTrust Shares. As promptly as
practicable, but not later than thirty (30) days, after the Effective Time of
the Merger, the Exchange Agent shall send or cause to be sent to each former
holder of record of the Bank Shares transmittal materials (the "Letter of
Transmittal") for use in exchanging their certificates formerly representing
the Bank Shares for the consideration provided for in this Agreement. The
Letter of Transmittal will contain instructions with respect to the surrender
of certificates representing the Bank Shares and the receipt of the
consideration contemplated by this Agreement and will require each holder of
Bank Shares to transfer good and marketable title to such Bank Shares to
SouthTrust, free and clear of all liens, claims and encumbrances. Amounts that
would have been payable to Dissenting Shareholders for Bank Shares but for the
fact of their dissent in accordance with the provisions of Section 2.1(d)
hereof shall be returned by the Exchange Agent to SouthTrust as promptly as
practicable.


                                       6
<PAGE>   15

                  (b)      At the Effective Time of the Merger, the stock 
transfer books of the Bank shall be closed as to holders of Bank Shares
immediately prior to the Effective Time of the Merger and no transfer of Bank
Shares by any such holder shall thereafter be made or recognized and each
outstanding certificate formerly representing the Bank Shares shall, without
any action on the part of any holder thereof, no longer represent the Bank
Shares. If, after the Effective Time of the Merger, certificates are properly
presented to the Exchange Agent, such certificates shall be exchanged for the
consideration contemplated by this Agreement into which the Bank Shares
represented thereby were converted in the Merger.

                  (c)      In the event that any holder of record as of the
Effective Time of the Merger of Bank Shares is unable to deliver the
certificate which represents such holder's Bank Shares, SouthTrust, in the
absence of actual notice that any Bank Shares theretofore represented by any
such certificate have been acquired by a bona fide purchaser, may, in its
discretion, deliver to such holder the consideration contemplated by this
Agreement and the amount of cash representing fractional SouthTrust Shares to
which such holder is entitled in accordance with the provisions of this
Agreement upon the presentation of all of the following:

                  (i)      an affidavit or other evidence to the reasonable
                           satisfaction of SouthTrust that any such certificate
                           has been lost, wrongfully taken or destroyed;

                  (ii)     such security or indemnity, including a bond, as may
                           be requested by SouthTrust or SouthTrust's transfer
                           agent, to indemnify and hold SouthTrust (and/or such
                           transfer agent) harmless; and

                  (iii)    evidence to the satisfaction of SouthTrust that such
                           holder is the owner of the Bank Shares theretofore
                           represented by each certificate claimed by such
                           holder to be lost, wrongfully taken or destroyed and
                           that such holder is the person who would be entitled
                           to present each such certificate for exchange
                           pursuant to this Agreement.

                  (d)      In the event that the delivery of the consideration
contemplated by this Agreement and the amount of cash representing fractional
SouthTrust Shares are to be made to a person other than the person in whose
name any certificate representing the Bank Shares surrendered is registered,
such certificate so surrendered shall be properly endorsed (or accompanied by
an appropriate instrument of transfer), with the signature(s) appropriately
guaranteed, and otherwise in proper form for transfer, and the person
requesting such delivery shall pay any transfer or other taxes required by
reason of the delivery to a person other than the registered holder of such
certificate surrendered or establish to the satisfaction of SouthTrust that
such tax has been paid or is not applicable.

                  (e)      No holder of Bank Shares shall be entitled to receive
any dividends or distributions declared or made with respect to the SouthTrust
Shares with a record date before the Effective Time of the Merger. After the
Effective Time of the Merger, and until properly surrendered and exchanged
pursuant to this Agreement, each outstanding certificate representing


                                       7
<PAGE>   16

Bank Shares, subject to this Section 2.4(e) shall be deemed to represent and
evidence for all corporate purposes only the right to receive the consideration
into which such Bank Shares were converted as of the Effective Time of the
Merger. Accordingly, among other matters, neither the consideration
contemplated by this Agreement, any amount of cash representing fractional
SouthTrust Shares nor any dividend or other distribution with respect to
SouthTrust Shares where the record date thereof is on or after the Effective
Time of the Merger shall be paid, and SouthTrust shall not be obligated to pay,
to the holder of any unsurrendered certificate or certificates representing the
Bank Shares until such holder shall surrender the certificate or certificates
representing the Bank Shares as provided for by this Agreement, and until such
holder becomes the record holder of the SouthTrust Shares issuable in the
Merger, such holder shall not be entitled to vote such SouthTrust Shares in
respect of any matter coming before the stockholders of SouthTrust. Subject to
applicable laws, following surrender of any such certificate or certificates,
there shall be paid to the holder of the certificate or certificates then
representing SouthTrust Shares issued in the Merger, without interest at the
time of such surrender, the consideration contemplated by this Agreement, the
amount of any cash representing fractional SouthTrust Shares and the amount of
any dividends or other distributions with respect to SouthTrust Shares to which
such holder is entitled as a holder of SouthTrust Shares in accordance with the
foregoing.

         Section 2.4       Laws of Escheat. If any of the consideration due or
other payments to be paid or delivered to the holders of Bank Shares is not
paid or delivered within the time period specified by any applicable laws
concerning abandoned property, escheat or similar laws, and if such failure to
pay or deliver such consideration occurs or arises out of the fact that such
property is not claimed by the proper owner thereof, SouthTrust or the Exchange
Agent shall be entitled to dispose of any such consideration or other payments
in accordance with applicable laws concerning abandoned property, escheat or
similar laws. Any other provision of this Agreement notwithstanding, none of
the Bank, SouthTrust, ST-Sub, ST-Bank, the Exchange Agent, nor any other person
acting on their behalf shall be liable to a holder of Bank Shares for any
amount paid or property delivered in good faith to a public official pursuant
to and in accordance with any applicable abandoned property, escheat or similar
law.

                           however, notwithstanding anything contained in this
                           Agreement to the contrary, Past Service Credit shall

to, the Securities Act or the Exchange Act), and will reimburse each of them
for any legal, accounting or other expenses reasonably incurred in connection
with investigating or defending any such actions, whether or not resulting in
liability, insofar as such losses, expenses, claims, damages or liabilities
arise out of or are based upon any untrue statement or alleged untrue statement
of material fact contained in the Registration Statement, the Proxy Statement
or any application for the approval of the transactions contemplated by this
Agreement filed with any Regulatory Authority or arise out of or are based upon
the omission or alleged omission to state therein a material fact necessary to

                  (b)      For a period of three (3) years after the Effective 
Time of the Merger, SouthTrust shall indemnify, defend and hold harmless each
person entitled to indemnification from the Bank (each, an "Indemnified Party")
against all liabilities arising out of actions or omissions occurring at or
prior to the Effective Time of the Merger (including, without limitation, the
transactions contemplated by this Agreement (to the same extent and subject to
the conditions set forth in the Bank's and the Bank's Articles of Incorporation
and Bylaws, in each case as in effect on the date hereof.

                  (c)      After the Effective Time of the Merger, directors,
officers and employees of the Bank, the Bank, except for the indemnification
rights provided for in this Section 6.4 above, shall have indemnification
rights having prospective application only. These prospective indemnification
rights shall consist of such rights to which directors, officers and employees
of SouthTrust and its subsidiaries would be entitled under the Restated
Certificate or Certificate or Articles of Incorporation and Bylaws of
SouthTrust or the particular subsidiary for which they are serving as officers,
directors or employees and under such directors' and officers' liability
insurance policy as SouthTrust may then make available to officers, directors
and employees of SouthTrust and its subsidiaries.

         (d)      SouthTrust shall use its best efforts (and the Bank shall
cooperate prior to the Effective Time of the Merger in these efforts) to
maintain in effect for a period of three (3) years after the Effective Time of
the Merger the Bank's existing directors' and officers' liability insurance
policy (provided that SouthTrust may substitute therefor (i) policies of at
least the same coverage and amounts containing terms and conditions which are
substantially no less advantageous or (ii) with the consent of the Bank (given
prior to the Effective Time of the Merger) any other policy with respect to
claims arising from facts or events which occurred prior to the Effective Time
of the Merger and covering persons who are currently covered by such insurance;
provided, that SouthTrust shall not be obligated to make premium payments for
such three (3)-year period in respect of such policy (or coverage replacing
such policy) which exceed, for the portion related to the Bank's and the Bank's
directors and officers, 150% of the annual premium payments on the Bank's
current policy, as in effect as of the date of this Agreement (the "Maximum
Amount"). If the amount of premium that is necessary to maintain or procure
such insurance coverage exceeds the Maximum Amount, SouthTrust shall use its
reasonable efforts to maintain the most advantageous policies of directors' and
officers' liability insurance obtainable for a premium equal to the Maximum
Amount.

                  (e)      If SouthTrust or any of its successors or assigns
shall consolidate with or merge into any other person and shall not be the
continuing and surviving person of such consolidation or merger, or shall
transfer all or substantially all of its assets to any person, then, and in
each case, proper provisions shall be made so that the successors and assigns
of SouthTrust shall assume the obligations set forth in this Section 6.4.

         Section 6.5       Current Information. During the period from the date 
of this Agreement to the Effective Time of the Merger or the time of
termination or abandonment hereunder, SouthTrust will cause one or more of its
designated representatives to confer on a regular and frequent basis with the
Bank and to report with respect to the general status and the ongoing
operations of SouthTrust.

         Section 6.6       Registration Statements.  Within ten (10) business
days after the Effective Time of the Merger, SouthTrust shall prepare and cause
the Post-Effective Registration Statement


                                       33
<PAGE>   42

to be filed with the SEC, provided, however, that if information relating to
the Bank, its agents or representatives, including its shareholders, has not
been supplied or has not been supplied sufficiently in advance to permit
SouthTrust to file the Post-Effective Registration Statement within the
required period of time, the ten business day period will not commence until
the last date such required information was provided to SouthTrust by, for or
on behalf of the Bank. SouthTrust shall provide a copy of the Post-Effective
Registration Statement, in its then current form, to the Bank within the five
(5) business day period prior to the Closing Date. SouthTrust shall use its
best efforts to cause the Post-Effective Registration Statement to be declared
effective under the Securities Act within forty five (45) days of the Effective
Time of the Merger and will use its best efforts to maintain the effectiveness
of the Post-Effective Registration Statement for a period of two (2) years
following the Effective Time of the Merger to permit the shareholders of the
Bank who receive SouthTrust Shares in the Merger to sell such SouthTrust Shares
through the NASDAQ/NMS. The Post-Effective Registration Statement will, at the
time it becomes effective, shall in all material respects conform to the
requirements of the Securities Act and the general rules and regulations of the
SEC under the Securities Act. The Bank will promptly furnish to SouthTrust the
information required to be included in the Post-Effective Registration
Statement with respect to its business and affairs before it is filed with the
SEC and again before any amendments are filed. SouthTrust shall take all
actions required to qualify or obtain exemptions from such qualifications for
the SouthTrust Shares to be issued in connection with the transactions
contemplated by this Agreement under applicable state blue sky securities laws,
as appropriate.

         Section 6.7       Reservation of Shares. SouthTrust shall reserve for
issuance such number of SouthTrust Shares as shall be necessary (i) to pay the
consideration contemplated in this Agreement and (ii) to comply with the
provisions of Section 2.2(b). If at any time the aggregate number of SouthTrust
Shares remaining unissued (or in treasury) shall not be sufficient to meet such
obligation, SouthTrust shall take all appropriate actions to increase the
amount of its authorized common stock.

         Section 6.8       Consideration. SouthTrust shall issue the SouthTrust
Shares and shall pay or cause to be paid all cash payments as and when the same
shall be required to be issued and paid pursuant to this Agreement.

transactions contemplated by this Agreement, which, in the case of (i) through

or any fact, event or condition which could reasonably be expected to result in
a Material Adverse Effect on the Bank and no fact, event or condition which

Agreement impractical because of any state of war, national emergency, banking
moratorium or general suspension of trading on NASDAQ/NMS, the New York Stock
Exchange or any other national securities exchange, shall have occurred between
the date of this Agreement and the Effective Time of the Merger.

Surviving Corporation or upon the consummation of the transactions contemplated
by this Agreement.

shall have delivered evidence that each Consent set forth in DISCLOSURE

or its subsidiaries, including, without limitation, any requirement that
SouthTrust sell or dispose of any significant amount of the assets of the Bank
or any other banking or other subsidiary of SouthTrust, provided that, except
for any such requirement relating to the above-described sale or disposition of
any significant assets of the Bank or any banking or other subsidiary of

exercise their right to dissent from the Merger and demand payment in cash for
the fair value of their shares, the transactions contemplated by this Agreement
fail to qualify for pooling of interests accounting treatment.

if the Merger shall not have occurred on or prior to November 30, 1998, or on
such other date as may be mutually agreed to by SouthTrust and the Bank,

                  (c)      by the Board of Directors of SouthTrust or the Bank

breach;

                  (d)      by the Board of Directors of SouthTrust or the Bank

                                       38

<PAGE>   47


such party to consummate the Merger (other than as contemplated by Section
10.1(e) of this Agreement) cannot be satisfied or fulfilled by the date
specified in Section 10.1(b) of this Agreement; or

                  (e) by the Board of Directors of SouthTrust or the Bank in
the event (i) any Consent of any Regulatory Authority required for consummation

time for the compliance or fulfillment by the other of any and all of the
other's obligations under this Agreement and to waive any or all of the
conditions to its obligations under this Agreement, except any condition,

applicable governmental regulation.

         Section 10.5 Non-Survival of Representations and Warranties. The

any instrument delivered by SouthTrust, ST-Bank or the Bank shall not survive

such) shall survive the Effective Time of the Merger; provided that no
representation, warranty or agreement of SouthTrust, ST-Bank, or the Bank
contained herein shall be deemed to be terminated or extinguished so as to
deprive SouthTrust or ST-Bank, on the one hand, and the Bank, on the other
hand, of any defense at law or in equity which any of them otherwise would have
to any claim

                                       39

known that any such representation or warranty was, is, might be or might have
been inaccurate in any respect.

         WHEREAS, effective July 14, 1998, the Bank, ST-Bank Texas, ST-Sub and

         3. Amendment to Section 1.1. The Merger Agreement is hereby amended by

                           shall be located at Birmingham, Alabama. The branch
                           offices of the Surviving Corporation shall be the

                  (d)      As of March 31, 1998, ST-Bank had total capital stock
                           of $9,006,600 divided into 1,020,000 shares of Common
                           Stock, par value $8.83 per share ("ST-Bank Shares").
                           As of March 31, 1998, the Bank had total capital

                           are held as treasury stock.

                  (e)      After the Effective Time of the Merger, the Surviving
                           Corporation shall have total capital stock of
                           $9,006,600 divided into 1,020,000 shares of ST-Bank
                           Shares, authorized, 1,020,000 shares of which shall

                  except where the failure to be so licensed or qualified (or

                  Material Adverse Effect on ST-Bank. True and correct copies of
                  the Articles of Association and the Bylaws of ST-Bank, each as

                                 AMENDMENT NO. 2
                                       TO
                          AGREEMENT AND PLAN OF MERGER


         This Amendment No. 2 (the "Amendment No. 2") is made this 21st day of
October, 1998, by and among SecurityBank, Texas, a Texas banking corporation
(the "Bank"), SouthTrust of Alabama, Inc., an Alabama corporation and a
wholly-owned subsidiary of SouthTrust (as defined herein) ("ST-Sub"), SouthTrust
Corporation, a Delaware corporation ("SouthTrust"), and SouthTrust Bank,
National Association, a national banking association ("ST-Bank").

         WHEREAS, the Bank, ST-Sub, SouthTrust and ST-Bank have entered into an
Agreement and Plan of Merger, effective July 14, 1998, as amended by Amendment
No. 1 to the Agreement and Plan of Merger, dated as of August 28, 1998 (as so
amended, the "Merger Agreement"), providing for the acquisition by ST-Sub of the
assets and the business of the Bank through the merger of the Bank with and into
ST-Bank (terms with their initial letter capitalized and not otherwise defined
herein have the meanings given them in the Merger Agreement);

         WHEREAS, Section 2.1(b) of the Merger Agreement provides that the
Merger Consideration to be received by the holders of the Bank Shares is the
number of SouthTrust Shares equal to the quotient of (i) $30,000,000 divided by
(ii) the Average Closing Price; provided that if the quotient is more than
785,675, then SouthTrust may, at its written election, refuse to increase the
Merger Consideration to more than 785,675 SouthTrust Shares, provided that the
Bank may elect to terminate this Agreement within three (3) business days after
such written election.

         WHEREAS, the parties intend that the Effective Time of the Merger be on
October 30, 1998;

         WHEREAS, the Average Closing Price computed based on the Effective Time
of the Merger occurring on October 30, 1998, would result in a quotient computed
pursuant to Section 2.1(b) in excess of 800,000;

         WHEREAS, the parties wish to amend the Merger Agreement, as set forth
herein;

         NOW THEREFORE, in consideration of the premises and mutual covenants,
representations, warranties and agreements contained herein, and for good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:


<PAGE>   2



         1. Amendment to Section 2.1(b). The Merger Agreement is hereby amended
by deleting Section 2.1(b) therein in its entirety and inserting in its place
and stead the following:

                  "(b) Subject to the terms and conditions of this Agreement,
         including, without limitation, Section 2.3 of this Agreement, and
         except with regard to Dissenting Shares (as defined in Section 2.1(d)
         of this Agreement) and the Bank Shares excluded in (a) above, each Bank
         Share outstanding immediately prior to the Effective Time of the Merger
         shall be converted into the right to receive the quotient of (i)
         800,000 shares (the "Merger Consideration") of the common stock of
         SouthTrust (and the rights associated therewith pursuant to a Rights
         Agreement dated February 22, 1989 between SouthTrust and Mellon Bank,
         N.A.) (together, the "SouthTrust Shares") divided by (ii) the number of
         Bank Shares outstanding immediately prior to the Effective Time of the
         Merger (hereinafter referred to as the "Conversion Ratio").

                  "Further, if the Effective Time of the Merger does not occur
         on or before the record date for the payment of the regular quarterly
         dividend on the SouthTrust Shares declared during the fourth quarter of
         1998, then, notwithstanding the foregoing, the number of SouthTrust
         Shares included in the Merger Consideration shall be increased by
         adding thereto the quotient of (A) the amount of such quarterly
         dividend divided by (B) the Average Closing Price(as defined below).

                  "For purposes of this Agreement, the term "Average Closing
         Price" shall mean the average of the daily last sales prices of
         SouthTrust Shares reported by the NasDaq-National Market System
         ("NASD/NMS") (as reported by The Wall Street Journal or, if not
         reported thereby, another authoritative source as chosen by SouthTrust)
         for the 20 consecutive full trading days in which such shares are
         traded on the NASDAQ/NMS ending at the close of trading on the tenth
         business day prior to the Effective Time of the Merger."

         2. Amendment to Section 10.1(b). The Merger Agreement is hereby amended
by deleting Section 10.1(b) therein in its entirety and inserting in its place
and stead the following:

                  "(b) by the Board of Directors of the Bank if the Merger shall
         not have occurred on or prior to October 30, 1998, or by the Board of
         Directors of SouthTrust or the Bank if the Merger shall not have
         occurred on or prior to November 30, 1998, or on such other respective
         dates as may be mutually agreed to by SouthTrust and the Bank, provided
         that the failure to consummate the Merger on or before such respective
         dates is not as a result of any breach of any of the representations,
         warranties, covenants or other agreements contained herein by the party
         electing to terminate pursuant to this Section 10.1(b);"

         3. Except as expressly amended herein, all other terms and conditions
of the Merger Agreement shall remain in force and effect.

Gentlemen:

                  In our capacity as counsel for SouthTrust Corporation, a
Delaware corporation ("SouthTrust"), we have examined the Registration Statement
on Form S-3 (the "Registration Statement"), in form as proposed to be filed by
SouthTrust with the Securities and Exchange Commission under the provisions of
the Securities Act of 1933, as amended, and relating to 800,000 shares of
Common Stock, par value $2.50 per share (the "Shares"), of SouthTrust and to
355,556 rights to purchase 1/100th of one share of Series A Junior Participating
Preferred Stock of SouthTrust (the "Rights"), which Shares and Rights are to be
offered by certain persons (the "Selling Stockholders") who acquired the Shares
and Rights on October 30, 1998 in connection with the merger of SecurityBank
Texas, a Texas banking corporation ("SecurityBank"), with and into SouthTrust
Bank, National Association ("ST-Bank"), pursuant to that certain Agreement and
Plan of Merger dated July 14, 1998, as amended on August 28, 1998 and on October
21, 1998, between SecurityBank, ST-Bank, SouthTrust and SouthTrust of Alabama,
Inc. The Selling Stockholders may, from time to time, offer and sell the Shares
and Rights associated therewith to the public pursuant to such Registration
Statement. In this connection, we have examined such records, documents and
proceedings as we have deemed relevant and necessary as a basis for the opinions
expressed herein.

                  Upon the basis of the foregoing, we are of the opinion that
the Shares and Rights described in the Registration Statement, to the extent
actually issued pursuant to the Merger, have been duly and validly authorized
and issued and are fully paid and nonassessable Shares and Rights of SouthTrust.

                  We hereby consent to the filing of this opinion with the
Securities and Exchange Commission as an exhibit to the above-referenced
Registration Statement. In addition, we hereby consent to the inclusion of the
statements made in reference to our firm under the caption "LEGAL OPINION" in
the Prospectus, which is a part of the Registration Statement.


                                           Very truly yours,
