         At the Special Meeting, you will be asked to consider and vote on a
proposal to approve an Agreement and Plan of Merger (the "Merger Agreement")
which provides for the merger (the "Merger") of Lake State with and into
SouthTrust Bank of Florida, N.A., an indirect subsidiary of SouthTrust
Corporation ("SouthTrust").  Upon consummation of the Merger, each share of
Lake State common stock issued and outstanding will be exchanged for 0.84
shares of SouthTrust common stock (subject to appropriate adjustment in the
event of certain circumstances), with cash being paid in lieu of issuing
fractional shares.

         Enclosed are the (i) Notice of Special Meeting, (ii) Proxy

Statement/Prospectus describes in more detail the Merger Agreement and the
proposed Merger, including a description of the conditions to consummation of
the Merger and the effects of the Merger on the rights of Lake State
shareholders.  Please read these materials carefully and consider thoughtfully

         THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AND CONSUMMATION OF THE MERGER CONTEMPLATED THEREBY, AND UNANIMOUSLY RECOMMENDS
THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

         It is important to understand that approval of the Merger Agreement
will require the affirmative vote of at least two-thirds of the votes entitled
to be cast at the Special Meeting by the holders of the issued and outstanding
shares of Lake State common stock.  Accordingly, whether or not you plan to
attend the Special Meeting, you are urged to complete, sign, and return
promptly the enclosed proxy card.  The proposed Merger is a significant step
for Lake State and your vote on this matter is of great importance.

         ON BEHALF OF THE BOARD OF DIRECTORS, I URGE YOU TO VOTE FOR APPROVAL
OF THE AGREEMENT BY MARKING THE ENCLOSED PROXY CARD "FOR" ITEM ONE.

         We look forward to seeing you at the Special Meeting.

                                  INTRODUCTION

GENERAL

         This Proxy Statement/Prospectus is being furnished to the holders of
common stock, par value $8.00 per share ("Lake State Common Stock"), of Lake
State Bank, a Florida banking corporation ("Lake State"), in connection with
the solicitation of proxies by the Board of Directors of Lake State for use at
a special meeting of shareholders of Lake State to be held on June 28, 1996 at
8:30 a.m., local time, at the principal executive offices of Lake State,
located at 21780 State Road 54, Lutz, Florida 33549, and at any postponement or
adjournment thereof (the "Special Meeting").

         The purpose of the Special Meeting is to consider and vote upon that
certain Agreement and Plan of Merger, dated as of February 28, 1996 (the
"Merger Agreement"), between Lake State and SouthTrust Bank of Florida,
National Association, a national banking association ("ST-Bank"), and joined in
by SouthTrust Corporation, a Delaware corporation ("SouthTrust"), and
SouthTrust of Florida, Inc., a Florida corporation and a wholly-owned
subsidiary of SouthTrust ("ST-Florida"), providing for the merger of Lake State
into ST-Bank (the "Merger") and, subject to rights of dissent and exclusive of
shares of Lake State Common Stock held in the treasury of Lake State, the
conversion in the Merger of each outstanding share of Lake State Common Stock
into 0.84 shares of common stock, par value $2.50 per share, of SouthTrust
("SouthTrust Common Stock").  No fractional shares of SouthTrust Common Stock
will be issued in the Merger, and, in lieu thereof, each holder of shares of
Lake State Common Stock who otherwise would have been entitled to receive a
fractional share of SouthTrust Common Stock will be entitled to receive a cash
payment in an amount equal to the product of (i) the fractional interest of a
share of SouthTrust Common Stock to which such holder otherwise would have been
entitled and (ii) the last sales price of such share of SouthTrust Common Stock
as reported on the Nasdaq National Market ("Nasdaq") on the last trading day
immediately preceding the Effective Time of the Merger (as defined below).

         The 0.84 shares of SouthTrust Common Stock for which each share of
Lake State Common Stock may be exchanged in the Merger had an aggregate market
value, based upon the average of the last sales price of SouthTrust Common
Stock for the five trading days immediately preceding May 29, 1996, of
approximately $27.76.  See "DESCRIPTION OF SOUTHTRUST CAPITAL STOCK--SouthTrust
Common Stock" and "MARKET AND DIVIDEND INFORMATION RESPECTING THE COMMON STOCK
OF SOUTHTRUST AND LAKE STATE."  Since the number of shares of SouthTrust Common
Stock to be received for each share of Lake State Common Stock in the Merger is
fixed, a change in the market price of SouthTrust Common Stock before the
Merger would affect the value of the SouthTrust Common Stock to be received in
the Merger in exchange for each share of Lake State Common Stock.  For
additional information regarding the terms of the Merger, see the Merger
Agreement which is attached hereto as Exhibit A and "THE MERGER."

         Subject to the approval of the Merger Agreement by the shareholders of
Lake State and the satisfaction or waiver of all conditions contained in the
Merger Agreement, the Merger will become effective on the date and at the time
on which the Merger is deemed effective by the Office of the Comptroller of the
Currency (the "OCC") (the "Effective Time of the Merger").  It is anticipated
that the Merger will become effective on or before June 28, 1996.

         This Proxy Statement/Prospectus was first sent or given to
shareholders of Lake State on or about May 30, 1996.  SouthTrust has filed a
Registration Statement with the Commission with respect to the shares of
SouthTrust Common Stock to be issued pursuant to the Merger.  This document
also constitutes the Prospectus of SouthTrust that is included as part of such
Registration Statement.  All information contained in this Proxy
Statement/Prospectus pertaining to SouthTrust, ST-Florida and ST-Bank was
supplied by SouthTrust, and all information contained in this Proxy
Statement/Prospectus pertaining to Lake State was supplied by Lake State.

         A copy of the Merger Agreement is attached hereto as Exhibit A and
incorporated herein by reference, and the description thereof contained in this
Proxy Statement/Prospectus is qualified in its entirety by reference to such
Exhibit A.

VOTING AT THE SPECIAL MEETING

         The Board of Directors of Lake State has fixed the close of business
on May 29, 1996 as the record date (the "Record Date") for the determination of
holders of shares of Lake State Common Stock entitled to notice of and to vote
at the Special Meeting.  On the Record Date, Lake State had outstanding 316,332
shares of Lake State Common Stock, which constituted the only outstanding class
of capital stock of Lake State entitled to notice of and to vote at the Special
Meeting.  The presence, in person or by proxy, of the holders of a majority of
the outstanding shares of Lake State Common Stock entitled to vote is necessary
to constitute a quorum at the Special Meeting.  The affirmative vote of the
holders of at least two-thirds of the outstanding shares of Lake State Common
Stock entitled to vote thereon is required to approve the Merger Agreement.
Each holder of record of shares of Lake State Common Stock on the Record Date
is entitled to one vote for each share of such stock held of record.

         As of the Record Date, Lake State directors and executive officers (a
total of 7 persons) beneficially owned a total of 207,509 shares of Lake State
Common Stock, representing approximately 65.59% of the shares of Lake State
Common Stock entitled to vote at the Special Meeting.  All of such directors
and officers have advised Lake State that, as of the date of the Proxy
Statement/Prospectus, they intend to vote for the approval of the Merger
Agreement.

         THE BOARD OF DIRECTORS OF LAKE STATE UNANIMOUSLY RECOMMENDS THAT
SHAREHOLDERS VOTE FOR  APPROVAL OF THE MERGER AGREEMENT.  SEE "THE MERGER -
BACKGROUND OF THE MERGER; REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD
OF DIRECTORS OF LAKE STATE."

         A proxy in the form enclosed, properly completed and returned in time
for the voting thereof at the Special Meeting, with instructions specified
thereon, will be voted in accordance with such instructions.  Only votes FOR a
particular matter constitute affirmative votes.  Votes that are withheld or
abstain, including broker non-votes, with respect to a matter are counted for
quorum purposes, but since they are not cast for a particular matter such votes
have the same effect as negative votes with respect to the proposal regarding
the Merger Agreement.  If no specification is made, a signed proxy will be
voted FOR approval of the Merger Agreement.  A proxy may be revoked at any time
prior to its exercise (i) by filing with the Secretary of Lake State either an
instrument revoking the proxy or a duly executed proxy bearing a later date or
(ii) by attending the Special Meeting and voting in person.  Attendance at the
Special Meeting will not in itself revoke a proxy.

         In addition to the use of the mail, proxies may be solicited by
telephone, telecopy or personally by the directors, officers and employees of
Lake State, who will receive no extra compensation for their services.  The
expenses of such solicitation will be paid by Lake State.  Lake State will
reimburse banks, brokerage firms and other custodians, nominees and fiduciaries
for reasonable expenses incurred by them in sending proxy soliciting material
to the beneficial owners of shares of Lake State Common Stock.

         SHAREHOLDERS OF LAKE STATE ARE REQUESTED TO COMPLETE, SIGN AND DATE
THE ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID
ENVELOPE WHETHER OR NOT THE SHAREHOLDER INTENDS TO ATTEND THE SPECIAL MEETING
IN PERSON.

largest banking company in the United States.  The largest bank subsidiary of
SouthTrust is SouthTrust Bank of Alabama, N.A., Birmingham, Alabama (the oldest
predecessor of which was incorporated in 1887), which had approximately $12.4
billion in total assets as of March 31, 1996.  Of SouthTrust's approximately
$22.6 billion in assets as of March 31, 1996, approximately $12.4 billion were
in Alabama, approximately $4.0 billion were in Georgia, and approximately $4.6
billion were in Florida.

         SouthTrust has pursued a strategy of acquiring banks and financial
institutions in or near major metropolitan or growth markets in Florida,
Georgia, North Carolina, Mississippi, South Carolina and Tennessee.  The
purpose of this strategy is to give SouthTrust business development
opportunities in metropolitan markets with favorable prospects for population
and per capita income growth.

         During 1995, SouthTrust effected acquisitions of seven financial
institutions, with total assets of approximately $713.0 million.  In addition,
during the first three months of 1996 SouthTrust has effected three
acquisitions of financial institutions, with total assets of approximately
$1.286 billion.  The following table represents certain information with
respect to transactions which are currently pending as of the date of this
Proxy Statement/Prospectus, including the Merger:

         SouthTrust anticipates that the acquisition of First State Bank of
Florida and Heritage Bancshares, Inc. will be accounted for pursuant to the
purchase method of accounting.  SouthTrust anticipates that the transactions
with Lake State and Prime Bank, each will be accounted for as a pooling of
interests.  Consummation of the pending transactions is subject, in each case,
to, among other things, approval by applicable regulatory authorities.

         As a routine part of its business, SouthTrust evaluates opportunities
to acquire bank holding companies, banks and other financial institutions.
Thus, at any particular point in time, including the date of this Proxy
Statement/Prospectus, the number of acquisition opportunities that may be
available to SouthTrust, and the stages of development of such activity, is
subject to change.  These transactions may involve SouthTrust acquiring such
financial institutions in exchange for cash or capital stock, and depending
upon the terms of these transactions, they may have a dilutive effect upon the
SouthTrust Common Stock to be issued to holders of Lake State Common Stock in
the Merger.

         The principal executive offices of SouthTrust are located at 420 North
20th Street, Birmingham, Alabama 35203, and its telephone number is (205)
254-5000.

  Lake State

         Lake State was organized under the laws of the State of Florida on
February 1, 1988 for the purpose of engaging in the commercial banking
business.  Lake State operates out of a single office in Lutz, Florida.  Lake
State is not a member of the Federal Reserve System but is a member of and its
deposits are insured by the Bank Insurance Fund ("BIF") of the Federal Deposit
Insurance Corporation ("FDIC").  Lake State is subject to comprehensive
regulation, examination and supervision by the FDIC and the Florida Department.
See "SUPERVISION AND REGULATION" and "CERTAIN INFORMATION CONCERNING THE
BUSINESS OF LAKE STATE."

         The business of Lake State consists primarily of attracting deposits
from the general public and using these funds, as well as loan repayments and
borrowings, to originate loans, primarily for individuals and small businesses.
Lake State's primary market areas for loans and deposits are Pasco County,
Florida, and Hillsborough County, Florida, and the total population of these
areas was approximately 299,000 and 865,000, respectively, as of April 1994.

         Lake State maintains its principal executive offices at 21780 State
Road 54, Lutz, Florida 33549 and the telephone number at such office is (813)
948-2265.

  SouthTrust of Florida, Inc.

         ST-Florida, a Florida corporation, is a wholly-owned subsidiary of
SouthTrust.  It owns the banking subsidiaries of SouthTrust which are located
in Florida, including ST-Bank.

  SouthTrust Bank of Florida

         ST-Bank is a national banking association with its main office located
in St. Petersburg, Florida.  As of March 31, 1996, ST-Bank operated 135 branch
offices in Florida.

SPECIAL MEETING

         The Special Meeting will be held at 8:30 a.m., local time, on June 28,
1996, at 21780 State Road 54, Lutz, Florida 33549 to consider and vote upon the
Merger Agreement.  Only holders of record of shares of Lake State Common Stock
as of the close of business on May 29, 1996, will be entitled to notice of and
to vote at the Special Meeting, including any adjournment thereof.

THE MERGER

  Terms of the Merger

         Subject to approval of the Merger Agreement by the shareholders of
Lake State at the Special Meeting, the receipt of required regulatory
approvals, and satisfaction of other conditions, Lake State will be merged into
ST-Bank pursuant to the Merger Agreement.  At the Effective Time of the Merger,
each outstanding share of Lake State Common Stock will be converted, subject to
rights of dissent and exclusive of shares of Lake State Common Stock held in
the treasury of Lake State, into the right to receive 0.84 shares of SouthTrust
Common Stock, which exchange ratio is subject to appropriate adjustment in the
event of certain stock splits and stock dividends effected by SouthTrust.  No
fractional shares of SouthTrust Common Stock will be issued in the Merger, and,
in lieu thereof, each holder of shares of Lake State Common Stock who otherwise
would have been entitled to receive a fractional share of SouthTrust Common
Stock will be entitled to receive a cash payment in an amount equal to the
product of (i) the fractional interest of a share of SouthTrust Common Stock to
which such holder otherwise would have been entitled and (ii) the last sales
price of such share of SouthTrust Common Stock as reported on Nasdaq on the
last trading day immediately preceding the Effective Time of the Merger.

         The 0.84 shares of SouthTrust Common Stock for which each outstanding
share of Lake State Common Stock may be exchanged in the Merger had an
aggregate value, based upon the average of the last sales price of SouthTrust
Common Stock for the five (5) trading days immediately preceding May 29, 1996
of approximately $27.76.

         As promptly as practicable after the Effective Time of the Merger,
SouthTrust or its agents, on behalf of ST-Florida, shall send or cause to be
sent to each former holder of record of Lake State Common Stock a letter of





                                       6
<PAGE>   9


transmittal for use in exchanging their stock certificates formerly
representing such Lake State Common Stock for certificates representing the
appropriate number of shares of SouthTrust Common Stock.

         Following the Merger, the existing office of Lake State will operate
as a full-service branch of ST-Bank.

  Reasons for the Merger

         The Board of Directors of Lake State considered a variety of factors
in evaluating and approving the Merger and the Merger Agreement, including (a)
the value of the consideration to be received by Lake State's shareholders
relative to the book value and earnings per share of Lake State Common Stock;
(b) certain information concerning the financial condition, results of
operations and business prospects of Lake State and SouthTrust; (c) the
marketability of Lake State Common Stock; (d) the competitive and regulatory
environment for financial institutions generally; (e) the fact that the Merger
will enable Lake State shareholders to exchange their shares of Lake State
Common Stock for shares of common stock of a larger combined entity, the stock
of which is more widely held and more actively traded and which historically
has paid cash dividends; (f) SouthTrust's ability to provide comprehensive
financial services in relevant markets; and (g) other pertinent information.
The Board of Directors of Lake State did not assign any relative weights to the
above factors, but it considered all of such factors to be material.  The Board
of Directors believes that it appropriately addressed all of the relevant
concerns in the proposed transaction with SouthTrust, and it concluded that the
terms of the transaction with SouthTrust are fair to the shareholders of Lake
State from a financial point of view.  Based on these factors, the Board of
Directors of Lake State determined that the Merger was in the best interests of
the shareholders of Lake State and approved the Merger Agreement.

  Vote Required

         The affirmative vote of the holders of at least two-thirds of the
outstanding shares of Lake State Common Stock entitled to vote thereon is
required to approve the Merger Agreement.  Directors and executive officers of
Lake State and their affiliates owned, as of the Record Date, directly or
indirectly, 207,509 shares of Lake State Common Stock, constituting
approximately 65.59% of the shares of Lake State Common Stock outstanding on
the Record Date for the Special Meeting.  It is anticipated that all shares
held by such persons will be voted for approval of the Merger Agreement.

  Recommendation of the Board of Directors

         THE MEMBERS OF THE BOARD OF DIRECTORS OF LAKE STATE HAVE UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND DETERMINED THAT THE MERGER IS FAIR, FROM A
FINANCIAL POINT OF VIEW, AND IS IN THE BEST INTERESTS OF LAKE STATE AND ITS
SHAREHOLDERS.  ACCORDINGLY, THE BOARD OF DIRECTORS OF LAKE STATE RECOMMENDS
THAT SHAREHOLDERS OF LAKE STATE VOTE IN FAVOR OF THE MERGER AGREEMENT.  This
recommendation is based on a number of factors discussed in this Proxy
Statement/Prospectus.  See "THE MERGER - Background of the Merger; Reasons for
the Merger; Recommendation of the Board of Directors of Lake State."

  Interests of Certain Named Persons in the Merger

         The Merger Agreement provides that the Board of Directors of ST-Bank,
following the Merger, shall consist of those persons who are serving in such
capacity immediately prior to the Effective Time of the Merger, as well as
those persons who may be designated in writing by SouthTrust at or prior to the
Effective Time of the Merger, and the officers of ST-Bank shall be those
persons who are serving in such capacity immediately prior to the Effective
Time of the Merger, as well as those persons who may be designated in writing
by SouthTrust at or prior to the Effective Time of the Merger.

         See "THE MERGER - Interests of Certain Named Persons in the Merger"
and "THE MERGER - Business and Management of Lake State Following the Merger;
Plans for Business of Lake State."

  Regulatory Approvals and Certain Other Conditions to the Merger; Waiver and
Amendment

         The respective obligations of SouthTrust and Lake State to consummate
the Merger are subject to the satisfaction of certain conditions, including,
among others, (i) the receipt of all required regulatory approvals with respect
to the Merger, (ii) the approval of the Merger Agreement by the requisite vote
of Lake State's shareholders, and (iii) certain other conditions customary in
transactions of this kind.

         The Merger is subject to approval by the OCC.  Accordingly, assuming
that all conditions to the Merger contained in the Merger Agreement are
satisfied or waived and that the Merger Agreement has not been terminated, the
Merger Agreement provides that the Merger shall occur as soon as practicable
following the later to occur of (i) the approval of the transactions pursuant
to the Merger Agreement by all required regulatory authorities, and (ii)
approval by the shareholders of Lake State of the Merger Agreement.

         On or about April 2, 1996, ST-Bank filed an application with the OCC
seeking approval to merge Lake State with and into ST-Bank.  That application
is expected to be approved on or about May 31, 1996.  Following OCC approval
there is a 15 day waiting period during which the Merger may not be consummated
and which commences the authority of the United States Department of Justice
(the "Justice Department") to challenge the Merger of Lake State into ST-Bank
on antitrust grounds.  This period is expected to expire on or about June 15,
1996.

         At any time before the Merger becomes effective, any party to the
Merger Agreement may waive conditions contained therein to its own obligations,
to the extent that such obligations, agreements and conditions are intended for
its own benefit.  In addition, the Merger Agreement may be amended by written
instrument signed on behalf of each of the parties thereto.

         See "THE MERGER - Regulatory Approvals and Certain Other Conditions to
the Merger; Waiver and Amendment."

  Termination

         The Merger Agreement may be terminated at any time prior to the
Effective Time of the Merger: (i) by the mutual consent in writing of
SouthTrust and Lake State, or (ii) by either SouthTrust or Lake State
individually, under certain specified circumstances, including if the Merger
shall not have occurred on or prior to October 31, 1996, provided that the
failure to consummate the Merger on or before such date is not caused by a
breach of the Merger Agreement by the party seeking to terminate.  See "THE
MERGER - Termination."

  Effective Time of the Merger

         The Merger will become effective on the date and at the time on which
the Merger is deemed effective by the OCC.  Subject to satisfaction of the
conditions contained in the Merger Agreement, the parties currently anticipate
that the Merger will become effective on or before June 28, 1996, although
there can be no assurance as to whether or when the Merger will become
effective.  See "THE MERGER - Effective Time of the Merger."

RIGHTS OF DISSENT AND APPRAISAL

         Any holder of shares of Lake State Common Stock is entitled to dissent
from the Merger and demand the fair value of the shares of Lake State Common
Stock held by such holder in cash, if such dissenting shareholder follows the
procedures provided by applicable law which are described elsewhere in this
Proxy Statement/Prospectus.  See "THE MERGER - Rights of Dissent and
Appraisal."

COMPARATIVE STOCK PRICES

         SouthTrust Common Stock is traded in the over-the-counter market
through the facilities of Nasdaq.  The market for shares of Lake State Common
Stock is not active and during the last two years, the sales price of shares of
Lake State Common Stock of which Lake State had knowledge ranged from $11.00 to
$13.00 per share.  The last sale of shares of Lake State Common Stock known to
Lake State occurred on December 21, 1995 at a sales price of $13.00 per share.

         The following table sets forth applicable last sales prices, and pro
forma equivalents based upon such last sales prices, for SouthTrust Common
Stock as of selected dates.

         per share of Lake State Common Stock.


         Lake State's shareholders are advised to obtain current market
quotations for or information regarding SouthTrust Common Stock and Lake State
Common Stock.  No assurance can be given as to the market price of SouthTrust
Common Stock or the value of Lake State Common Stock at any time before the
Effective Time of the Merger or as to the market price of SouthTrust Common
Stock at any time thereafter.  Because the exchange ratio of Lake State Common
Stock for SouthTrust Common Stock is fixed, it will not compensate Lake State's
shareholders for decreases in the market price of SouthTrust Common Stock which
could occur before the Effective Time of the Merger.  In the event the market
price for SouthTrust Common Stock were to decrease, the value of the SouthTrust
Common Stock to be received in the Merger in exchange for Lake State Common
Stock would decrease.  It also should be noted that, in the event the market
price of SouthTrust Common Stock were to increase, the value of the SouthTrust
Common Stock to be received in the Merger in exchange for Lake State Common
Stock would increase.

         See "MARKET AND DIVIDEND INFORMATION RESPECTING THE COMMON STOCK OF
SOUTHTRUST AND LAKE STATE."

RESALE OF SOUTHTRUST COMMON STOCK RECEIVED IN THE MERGER

         The shares of SouthTrust Common Stock to be issued pursuant to the
Merger Agreement have been registered under the Securities Act, thereby
allowing such shares to be sold without restriction by shareholders of Lake
State who are not deemed to be "affiliates" (as that term is defined in the
rules under the Securities Act) of Lake State and who do not become affiliates
of SouthTrust.  The shares of SouthTrust Common Stock to be issued to
affiliates of Lake State may be resold only pursuant to an effective
registration statement, pursuant to Rule 145 under the Securities Act (which,
among other things, permits the resale of securities subject to certain volume
limitations) or in transactions otherwise exempt from registration under the
Securities Act.  SouthTrust will not be obligated and does not intend to
register its shares under the Securities Act for resale by shareholders who are
affiliates.  Since the aggregate number of shares of SouthTrust Common Stock
issuable in the Merger is less than any applicable volume limitation under Rule
145, an affiliate of Lake State who otherwise complies with Rule 145, and
subject to the undertaking described below, will be free to resell, during any
given three-month period, all of the shares of SouthTrust Common Stock received
by such affiliate in the Merger.

         In addition, at or prior to the Effective Time of the Merger, each
affiliate of Lake State will deliver to SouthTrust a letter agreement
pertaining to the limitations on the transferability of such affiliate's shares
of SouthTrust Common Stock acquired in the Merger, and whereby such affiliate
shall represent and warrant, among other things, that he or she shall not sell,
pledge, transfer, or otherwise dispose of such shares of SouthTrust Common
Stock (i) in violation of the Securities Act or the rules and regulations
thereunder, and (ii) until such time as financial results covering at least 30
days of combined operations of Lake State and SouthTrust have been published
within the meaning of Section 201.01 of the Commission's Codification of
Financial Reporting Policies.

  See "THE MERGER - Resale of SouthTrust Common Stock Received in the Merger."

DIFFERENCES IN RIGHTS OF LAKE STATE SHAREHOLDERS

         Upon consummation of the Merger, Lake State shareholders will become
SouthTrust stockholders.  As a result, their rights as shareholders, which now
are governed by Florida corporate and banking law and Lake State's Articles of
Incorporation and Bylaws, will be governed by Delaware corporate law and
SouthTrust's Restated Certificate of Incorporation and Bylaws.  Because of
certain differences between the provisions of Florida law and





                                       9
<PAGE>   12


Delaware corporate law and of Lake State's Articles of Incorporation and Bylaws
and SouthTrust's Restated Certificate of Incorporation and Bylaws, the current
rights of Lake State shareholders will change after the Merger.  Some of these
differences include anti-takeover provisions applicable to SouthTrust.  See
"COMPARISON OF THE COMMON STOCK OF SOUTHTRUST AND LAKE STATE."

ACCOUNTING TREATMENT

         The Merger will be accounted for by SouthTrust as a pooling of
interests.  See "THE MERGER - Accounting Treatment."

TAX TREATMENT

         Lake State has received an opinion of Bradley, Arant, Rose & White to
the effect that, for federal income tax purposes, (i) the Merger will qualify
as a reorganization under Section 368(a)(1)(C) of the Internal Revenue Code of
1986, as amended (the "Code"); (ii) no gain or loss will be recognized by
holders of shares of Lake State Common Stock who receive SouthTrust Common
Stock in the Merger (except in connection with the receipt of cash in lieu of
fractional interests in shares of SouthTrust Common Stock); and (iii) the basis
of the SouthTrust Common Stock received by the shareholders of Lake State
pursuant to the Merger and the holding period therefor will be the same as the
basis and holding period of the Lake State Common Stock surrendered in exchange
therefor.  See "CERTAIN FEDERAL INCOME TAX CONSIDERATIONS."

         THE FEDERAL, STATE AND LOCAL TAX CONSEQUENCES MAY VARY FOR EACH HOLDER
OF SHARES OF LAKE STATE COMMON STOCK.  LAKE STATE SHAREHOLDERS ARE URGED TO
CONSULT THEIR OWN TAX AND FINANCIAL ADVISORS AS TO THE EFFECT OF INCOME TAX AND
OTHER TAX CONSEQUENCES ON THEIR OWN PARTICULAR FACTS.

EQUIVALENT SHARE DATA

         The following summary presents comparative historical unaudited per
share data for both SouthTrust and Lake State.  The pro forma amounts assume
the Merger was effective as of the commencement of the periods presented and
was accounted for as a pooling of interests.  SouthTrust's pro forma amounts
represent the combined pro forma results, and Lake State pro forma equivalent
amounts are computed by multiplying the pro forma amounts by a factor of 0.84
to reflect the exchange ratio in the Merger of 0.84 shares of SouthTrust Common
Stock for each share of Lake State Common Stock.  The data presented should be
read in conjunction with the historical financial statements and the related
notes thereto included elsewhere herein or incorporated by reference herein.

         SouthTrust anticipates that the acquisition of First State Bank of
Florida and Heritage Bancshares, Inc. will be accounted for pursuant to the
purchase method of accounting.  SouthTrust anticipates that the transactions
with Lake State and Prime Bank, each will be accounted for as a pooling of
interests.  Consummation of the pending transactions is subject, in each case,
to, among other things, approval by applicable regulatory authorities.

         As a routine part of its business, SouthTrust evaluates opportunities
to acquire bank holding companies, banks and other financial institutions.
Thus, at any particular point in time, including the date of this Proxy
Statement/Prospectus, discussions and, in some cases, negotiations and due
diligence activities looking toward or culminating in the execution of
preliminary or definitive documents respecting potential acquisitions may occur
or be in progress.  These transactions may involve SouthTrust acquiring such
financial institutions in exchange for cash or capital stock, and depending
upon the terms of these transactions, they may have a dilutive effect upon the
SouthTrust Common Stock to be issued to holders of Lake State Common Stock in
the Merger.

of Lake State Common Stock who otherwise would have been entitled to receive a
fractional share of SouthTrust Common Stock will be entitled to receive a cash
payment in an amount equal to the product of (i) the fractional interest of a
share of SouthTrust Common Stock to which such holder otherwise would have been
entitled and (ii) the last sales price of such share of SouthTrust Common Stock
as reported by Nasdaq on the last trading day preceding the Effective Time of
the Merger.

         Subject to the satisfaction or waiver of the conditions contained in
the Merger Agreement, the Merger Agreement provides that the Effective Time of
the Merger will occur as soon as practicable after the later to occur of (i)
the approval of the transactions pursuant to the Merger Agreement by all
required regulatory authorities,  (ii) the expiration of 15 days, or such
longer period in the event that the OCC receives adverse comments regarding the
Merger from the Attorney General of the United States (including any extension

State of the Merger.  The Merger will become effective on the date and at the
time on which the Merger is deemed effective by the OCC.

BACKGROUND OF THE MERGER; REASONS FOR MERGER; RECOMMENDATION OF THE BOARD OF
DIRECTORS OF LAKE STATE

         In November 1995, representatives of the Board of Directors of Lake
State were approached by representatives of ST-Bank regarding a possible
acquisition of Lake State.  Discussions between such representatives regarding
a possible business combination continued between November 1995 and January
1996.

         During this time, representatives of SouthTrust and Lake State
conducted various due diligence activities and negotiated the terms and
conditions to be included in a definitive merger agreement.  At a Board of
Directors meeting held on January 10, 1996, the Board of Directors of Lake
State met to review and consider the Merger Agreement.  At such Board of
Directors meeting, all of the directors of Lake State present at the meeting
voted to approve the Merger and the Merger Agreement, with such changes as the
President and Chief Executive Officer of Lake State determined, in consultation
with legal counsel and consistent with the terms of the Merger Agreement and
the discussions at the meeting, would be appropriate.  The Merger Agreement
between Lake State and ST-Bank, joined in by SouthTrust and ST-Florida, was
executed as of February 12, 1996, and, subsequent thereto, the members of the
Board of Directors of Lake State approved the Merger and the execution and
delivery of the Merger Agreement.  All of the directors and officers of Lake
State have advised Lake State that, as of the date of the Proxy
Statement/Prospectus, they intend to vote for the approval of the Merger
Agreement.

         The 0.84 shares of SouthTrust Common Stock to be exchanged for each
share of Lake State Common Stock reflect prices that were negotiated on an
arm's-length basis between representatives of Lake State and representatives of
SouthTrust.  There was no affiliation, relationship, understanding or
transaction between Lake State and its representatives, on one hand, and
SouthTrust and ST-Bank, and their representatives, on the other hand, prior to
the execution of the Merger Agreement.

         The Board of Directors of Lake State considered a variety of factors
in evaluating and approving the Merger and the Merger Agreement, including (a)
the value of the consideration to be received by Lake State's shareholders
relative to the book value and earnings per share of Lake State Common Stock;
(b) certain information concerning the financial condition, results of
operations and business prospects of Lake State and SouthTrust; (c) the
marketability of Lake State Common Stock; (d) the competitive and regulatory
environment for financial institutions generally; (e) the fact that the Merger
will enable Lake State shareholders to exchange their shares of Lake State
Common Stock for shares of common stock of a larger combined entity, the stock
of which is more widely held and more actively traded and which historically
has paid cash dividends; (f) SouthTrust's ability to provide comprehensive
financial services in relevant markets; and (g) other pertinent information.
The Board of Directors of Lake State did not assign any relative weights to the
above factors, but it considered all of such factors to be material.  The Board
of Directors believes that it appropriately addressed all of the relevant
concerns in the proposed transaction with SouthTrust, and it concluded that the
terms of the transaction with SouthTrust are fair to the shareholders of Lake
State from a financial point of view.  Based on these factors, the Board of
Directors of Lake State determined that the Merger was in the best interests of
the shareholders of Lake State and approved the Merger Agreement.

         THE MEMBERS OF THE BOARD OF DIRECTORS OF LAKE STATE HAVE UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND DETERMINED THAT THE MERGER IS FAIR, FROM A
FINANCIAL POINT OF VIEW, AND IS IN THE BEST INTERESTS OF LAKE STATE AND ITS
SHAREHOLDERS.  ACCORDINGLY, THE BOARD OF DIRECTORS OF LAKE STATE RECOMMENDS
THAT SHAREHOLDERS OF LAKE STATE VOTE IN FAVOR OF THE MERGER AGREEMENT.

         SouthTrust is engaging in the transactions pursuant to the Merger
because the Merger is consistent with its expansion strategy within the
southeastern United States and because the acquisition of Lake State will
augment SouthTrust's existing market share in the west Florida banking market
and enhance its competitive position in such market.

INTERESTS OF CERTAIN NAMED PERSONS IN THE MERGER

         The Merger Agreement provides that the Board of Directors of ST-Bank,
following the Merger, shall consist of those persons who are serving in such
capacity immediately prior to the Effective Time of the Merger, as well as
those persons who may be designated in writing by SouthTrust at or prior to the
Effective Time of the Merger, and the officers of ST-Bank shall be those
persons who are serving in such capacity immediately prior to the Effective
Time of the Merger, as well as those persons who may be designated in writing
by SouthTrust at or prior to the Effective Time of the Merger.





                                       16
<PAGE>   19


         Pursuant to the Agreement, appropriate steps shall be taken to
terminate all employee benefit plans of Lake State as of the Effective Time of
the Merger or as promptly as practicable thereafter.  Following the termination
of all such employee benefit plans, and subject to certain conditions described
below, SouthTrust has agreed that the officers and employees of Lake State who
SouthTrust or any of its affiliates employs shall be eligible to participate in
the employee benefits plans of SouthTrust, including welfare and fringe benefit
plans, on the same basis as and subject to the same conditions as are
applicable to any newly-hired employee of SouthTrust; provided, however, that
(a) with respect to SouthTrust's group medical insurance plan, SouthTrust shall
credit each such employee for eligible expenses incurred by such employee and
his or her dependents (if applicable) under Lake State's group medical
insurance plan during the current calendar year for purposes of satisfying the
deductible provisions under SouthTrust's plan for such current year, and
SouthTrust shall waive all waiting periods under said plans for pre-existing
conditions; and (b) credit for each such employee's past service with Lake
State prior to the Effective Time of the Merger shall be given by SouthTrust to
employees for purposes of:  (i) determining vacation and sick leave benefits
and accruals, in accordance with the established policies of SouthTrust; and
(ii) establishing eligibility for participation in, and vesting under,
SouthTrust's employee benefits plans (including welfare and fringe benefit
plans but such credit for past service shall not be given to any such employee
for purposes of establishing eligibility for participation in the 1990
Discounted Stock Plan of SouthTrust), and for purposes of determining the
scheduling of vacations and other determinations which are made based on length
of service;  SouthTrust has further agreed that for purposes of determining
eligibility to participate in, and vesting in accrued benefits under the
SouthTrust Corporation Revised Retirement Income Plan (the "Retirement Plan")
and SouthTrust Corporation Employees' Profit Sharing Plan (the "Profit Sharing
Plan"), employment with Lake State shall be credited as if it were employment
with SouthTrust, but such service shall not be credited for the purposes of
determining benefit accrual under the Retirement Plan.

EFFECT OF MERGER ON LAKE STATE COMMON STOCK

         At the Effective Time of the Merger, each outstanding share of Lake
State Common Stock, other than shares of Lake State Common Stock held by
shareholders who have dissented from the Merger, as discussed below, and shares
of Lake State Common Stock held in Lake State's treasury, shall be converted
into the right to receive 0.84 shares of SouthTrust Common Stock which exchange
ratio is subject to appropriate adjustment in the event of stock splits and
stock dividends effected by SouthTrust.  No fractional shares of SouthTrust
Common Stock will be issued in the Merger, and, in lieu thereof, each holder of
a share of Lake State Common Stock that otherwise would have been entitled to
receive a fractional share of SouthTrust Common Stock will be entitled to
receive a cash payment in an amount equal to the product of (i) the fractional
interest of a share of SouthTrust Common Stock to which such holder otherwise
would have been entitled, and (ii) the last sales price of such share of
SouthTrust Common Stock as reported on Nasdaq on the last trading day
immediately preceding the Effective Time of the Merger.

         Because the exchange ratio of shares of SouthTrust Common Stock for
Lake State Common Stock is fixed, it will not compensate Lake State's
shareholders for decreases in the market price of SouthTrust Common Stock which
could occur before the Effective Time of the Merger.  In the event the market
price of SouthTrust Common Stock decreases, the value of the SouthTrust Common
Stock to be received in the Merger in exchange for Lake State Common Stock
would decrease.  Lake State's shareholders are advised to obtain current market
quotations for and information regarding SouthTrust Common Stock and Lake State
Common Stock.  On May 28, 1996, the most recent date practicable preceding the
date of this Proxy Statement/Prospectus, the last sales price of SouthTrust
Common Stock was $27.50 per share.  In the event the market price of SouthTrust
Common Stock increases, the value of the SouthTrust Common Stock to be received
in the Merger in exchange for Lake State Common Stock would increase.  Lake
State's shareholders are advised to obtain current market quotations for and
information regarding SouthTrust Common Stock and Lake State Common Stock.  No
assurance can be given as to the market price of SouthTrust Common Stock or the
value of Lake State Common Stock on the date of the Effective Time of the
Merger or as to the market price of SouthTrust Common Stock thereafter.

EFFECTIVE TIME OF THE MERGER

         The Merger will become effective after the receipt of final approval
from the OCC and acknowledgement by the OCC of the effectiveness of the Merger.
The Merger Agreement provides that the parties thereto will cause such Articles
of Merger and notice of Merger to be filed after each of the conditions to
consummation of the Merger has been satisfied or waived.  The Merger cannot
become effective until Lake State's shareholders have approved the Merger
Agreement and all required regulatory approvals and actions have been obtained
and taken.  Subject to





                                       17
<PAGE>   20


satisfaction of the conditions contained in the Merger Agreement, the parties
currently anticipate that the Merger will become effective on or before June
28, 1996 although there can be no assurance as to whether or when the Merger
will become effective.

EXCHANGE OF STOCK CERTIFICATES

         As soon as practicable after the Effective Time of the Merger,
SouthTrust will deliver the total consideration to be paid by SouthTrust for
the shares of Lake State Common Stock to such institution as SouthTrust may
designate, which institution will act as the exchange agent for the transaction
(the "Exchange Agent").  As promptly as practicable after the Effective Time of
the Merger, the Exchange Agent shall send a letter of transmittal to each
former holder of record of shares of Lake State Common Stock for use in
exchanging their certificates formerly representing shares of Lake State Common
Stock for exchange and conversion in accordance with the procedures provided
for therein and in the Merger Agreement.  The letter of transmittal will
contain detailed instructions concerning the manner of executing and submitting
such stock certificates.  At the Effective Time of the Merger, the holders of
shares of Lake State Common Stock will cease to be shareholders of Lake State
and will have no voting or other rights with respect to shares of Lake State
Common Stock, other than the right to receive in the Merger shares of
SouthTrust Common Stock upon surrender of the stock certificates respecting
their shares of Lake State Common Stock.  As of the Effective Time of the
Merger and except as otherwise indicated below, all holders of shares of Lake
State Common Stock shall be deemed to be holders of the shares of SouthTrust
Common Stock into which such shares of Lake State Common Stock shall have been
converted in the Merger, whether or not they surrender the stock certificates
representing their shares of Lake State Common Stock.  Such holders shall be
entitled to all dividends or distributions in respect of shares of SouthTrust
Common Stock where the record date for the payment of such dividends or
distributions occurs on or after the Effective Time of the Merger; however, no
such dividends or distributions shall be paid to holders of any unsurrendered
certificate or certificates representing Lake State Common Stock, and
SouthTrust shall not be obligated to deliver any of the consideration to which
any holder of Lake State Common Stock is entitled as a result of the Merger or
any cash payment in lieu of a fractional interest in SouthTrust Common Stock
until such holder surrenders the certificate or certificates representing Lake
State Common Stock as provided for in the Merger Agreement.  Until the stock
certificates evidencing the shares of Lake State Common Stock are surrendered
pursuant to the Merger Agreement, no stock certificates representing shares of
SouthTrust Common Stock will be delivered or remitted to such holders, and,
until such holders become record holders of SouthTrust Common Stock, such
holders shall not be entitled to vote the shares of SouthTrust Common Stock
received in the Merger.  In addition, holders of shares of Lake State Common
Stock will not be entitled to receive any interest respecting any dividends or
distributions payable in respect of shares of SouthTrust Common Stock, and
SouthTrust, after the lapse of the appropriate time period and in accordance
with the applicable laws of escheat or abandoned property, may remit any
unclaimed funds or unclaimed stock certificates representing shares of
SouthTrust Common Stock to state officials under the applicable laws of escheat
or abandoned property.

RESALE OF SOUTHTRUST COMMON STOCK RECEIVED IN THE MERGER

         The shares of SouthTrust Common Stock to be issued pursuant to the
Merger Agreement have been registered under the Securities Act, thereby
allowing such shares to be sold without restriction by shareholders of Lake
State who are not deemed to be "affiliates" (as that term is defined in the
rules under the Securities Act) of Lake State and who do not become affiliates
of SouthTrust.  The shares of SouthTrust Common Stock to be issued to
affiliates of Lake State may be resold only pursuant to an effective
registration statement, pursuant to Rule 145 under the Securities Act (which,
among other things, permits the resale of securities subject to certain volume
limitations) or in transactions otherwise exempt from registration under the
Securities Act.  SouthTrust will not be obligated and does not intend to
register its shares under the Securities Act for resale by shareholders who are
affiliates.  Since the aggregate number of shares of SouthTrust Common Stock
issuable in the Merger is less than any applicable volume limitation under Rule
145, an affiliate of Lake State who otherwise complies with Rule 145, and
subject to the undertaking described below, will be free to resell, during any
given three-month period, all of the shares of SouthTrust Common Stock received
by such affiliate in the Merger.

         At or prior to the Effective Time of the Merger, each such person
deemed an affiliate of Lake State will deliver to SouthTrust a letter agreement
pertaining to the limitations on the transferability of such affiliate's shares
of SouthTrust Common Stock acquired in the Merger, and whereby such affiliate
shall represent and warrant, among other things, that he or she shall not sell,
pledge, transfer, or otherwise dispose of such shares of SouthTrust Common
Stock (i) in violation of the Securities Act or the rules and regulations
thereunder, and (ii) until such time





                                       18
<PAGE>   21


as financial results covering at least 30 days of combined operations of Lake
State and SouthTrust have been published within the meaning of Section 201.01
of the Commission's Codification of Financial Reporting Policies.

ACCOUNTING TREATMENT

         The Merger will be accounted for by SouthTrust as a pooling of
interests.  Under the pooling of interests method of accounting, the recorded
amounts of the assets and liabilities of Lake State and SouthTrust will be
carried forward at their previously recorded amounts.  For information
concerning certain restrictions to be imposed on the transferability of the
shares of SouthTrust Common Stock received by the affiliates of Lake State in
the Merger in order, among other things, to assure the availability of pooling
of interests accounting treatment, see "Resale of SouthTrust Common Stock
Received in the Merger."

REGULATORY APPROVALS AND CERTAIN OTHER CONDITIONS TO THE MERGER; WAIVER AND
AMENDMENT

         The Merger is subject to approval by the OCC.  Accordingly, assuming
that all conditions to the Merger contained in the Merger Agreement are
satisfied or waived and that the Merger Agreement has not been terminated, the
Merger Agreement provides that the Merger shall be consummated as soon as
practicable following the later to occur of (i) the approval of the
transactions pursuant to the Merger Agreement by all required regulatory
authorities, including the OCC, and (ii) approval by the shareholders of Lake
State of the Merger Agreement.

         On April 2, 1996, ST-Bank filed with the OCC an application seeking
approval to merge Lake State with ST-Bank.  The application to the OCC was is
expected to be approved on or about May 31, 1996.  Following OCC approval there
is a 15 day waiting period during which the Merger may not be consummated and
during which the Justice Department may challenge the Merger of Lake State into
ST-Bank on antitrust grounds.  This period is expected to expire on or about
June 15, 1996.

         There can be no assurance that any applicable regulatory authority
will approve or take other required action with respect to the Merger or as to
the date of such regulatory approval or other action.  SouthTrust and Lake
State are not aware of any governmental approvals or actions that are required
in order to consummate the Merger except as described above.  Should such other
approval or action be required, it is contemplated that SouthTrust and Lake
State would seek such approval or action.  There can be no assurance as to
whether or when any such other approval or action, if required, could be
obtained.

         In addition to receipt of all necessary regulatory approvals and the
expiration of all required notice and waiting periods following the granting of
such approvals, and the approval of the Merger Agreement by the requisite vote
of the shareholders of Lake State, consummation of the Merger is subject to the
satisfaction of certain other conditions on or before the Effective Time of the
Merger.  Such additional conditions include, among others, the following:

                 (a)      the Proxy Statement/Prospectus shall have been filed
         with the Commission and shall have been cleared thereby or otherwise
         authorized for mailing, and the Registration Statement shall have been
         filed with and declared effective by the Commission and shall not be
         the subject of any stop order or proceedings seeking any stop order;

                 (b)      the accuracy of the representations and warranties of
         SouthTrust, ST-Florida, ST-Bank and Lake State made in the Merger
         Agreement and the performance, in all material respects, of their
         respective obligations thereunder;

                 (c)      There shall be no actual or threatened causes of
         action, investigations or proceedings (i) challenging the validity or
         legality of the Merger Agreement or the consummation of the
         transactions contemplated by the Merger Agreement, or (ii) seeking
         damages in connection with the transactions contemplated by the Merger
         Agreement, or (iii) seeking to restrain or invalidate the transactions
         contemplated by the Merger Agreement which, in the case of (i) through
         (iii) and in the reasonable judgment of either SouthTrust or Lake
         State, based on advice of counsel, would have a material adverse
         effect with respect to the interests of SouthTrust or Lake State as
         the case may be;





                                       19
<PAGE>   22


                 (d)      there shall not have been any action taken, or any
         statute, rule, regulation or order enacted, entered, enforced or
         deemed applicable to the Merger, by any Regulatory Authority (as
         defined in the Merger Agreement) which, in connection with the grant
         of any Consent (as defined in the Merger Agreement) by any Regulatory
         Authority, imposes any materially adverse requirement upon SouthTrust
         or its subsidiaries, including, without limitation, any requirement
         that SouthTrust sell or dispose of any significant amount of the
         assets of Lake State 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
         Lake State or any banking or other subsidiary of SouthTrust, no such
         term or condition imposed by any Regulatory Authority in connection
         with the grant of any Consent by any Regulatory Authority, shall be
         deemed to be a materially adverse requirement unless it materially
         differs from terms and conditions customarily imposed by any such
         entity in connection with the acquisition of banks under similar
         circumstances;

                 (e)      there shall have been no: (i) determination by Lake
         State that any fact, event or condition exists or has occurred that,

         effect on the condition of SouthTrust on a consolidated basis or the
         consummation of the transactions contemplated by the Merger Agreement,
         or (B) would render the Merger or the other transactions contemplated
         by the Merger Agreement impractical because of any state of war,

         trading on Nasdaq, the New York Stock Exchange, Inc. or other national
         securities exchange; or (ii) determination by SouthTrust that any
         fact, event or condition exists or has occurred, that, in the judgment

         contemplated by the Merger Agreement, (B) would be of such
         significance with respect to the business or economic benefits
         expected to be obtained by SouthTrust pursuant to the Merger Agreement
         to render inadvisable the consummation of the transaction, (C) would
         be materially adverse to the interests of SouthTrust on a consolidated
         basis, or (D) would render the Merger or the other transactions
         contemplated by the Merger Agreement impractical because of any state

         of trading on Nasdaq, the New York Stock Exchange, Inc. or other
         national securities exchange;

                 (h)      the holders of not more than five percent (5%) of the

         cash for the fair or appraised value of their shares;

                 (i)      each party shall have obtained the consent or

         counsel to SouthTrust concerning certain aspects, including certain
         tax aspects, of the transactions contemplated by the Merger Agreement.

         At any time prior to the Effective Time of the Merger, any party to
the Merger Agreement may waive any default in the performance of any term of
the Merger Agreement by another party, may waive or extend the time for the
compliance or fulfillment by the other of any and all of the other's conditions
under the Merger Agreement,





                                       20

or may waive any or all of the conditions contained therein to its own
obligations, except any condition which, if not satisfied, would result in the
violation of any law or any applicable governmental regulation.  In addition,
the Merger Agreement may be amended by written instruments signed on behalf of
each of the parties thereto.

TERMINATION

         The Merger Agreement may be terminated at any time prior to the

conditions precedent to the obligations of the terminating party to consummate
the Merger cannot be satisfied or fulfilled;

         (d)     by SouthTrust if:  (i) SouthTrust shall have determined that
any fact, event or condition exists that, in the judgment of SouthTrust, (A) is
materially at variance with any warranty or representation of Lake State set
forth in the Merger Agreement or is a material breach of any covenant or
agreement of Lake State contained in the Merger Agreement, (B) has a material
adverse effect or can be reasonably foreseen to have a material adverse effect
upon the Condition of Lake State on a consolidated basis or upon the
consummation of the transactions contemplated by the Merger Agreement, (C)
would be materially adverse to the interests of SouthTrust and ST-FL on a
consolidated basis, (D) would be of such significance with respect to the
business or economic benefits expected to be obtained by SouthTrust under the
Merger Agreement so as to render inadvisable consummation of the transactions
contemplated in the Merger Agreement, (E) renders the Merger or the other
transactions contemplated by the Merger Agreement impractical because of any
state of war, national emergency, banking moratorium or general suspension of
trading on Nasdaq, the New York Stock Exchange, Inc. or any other national

litigation (A) challenging the validity or legality of the Merger Agreement or

the consummation of the transactions contemplated by the Merger Agreement; or

         (e)     by Lake State if (i) Lake State shall have determined that any

materially at variance with any warranty or representation of SouthTrust, ST-FL
or ST-Bank contained in the Merger Agreement or is a material breach of any
covenant or agreement of SouthTrust, ST-FL or ST-Bank contained in the Merger
Agreement, or (B) has a material adverse effect or can be reasonably seen to
have a material adverse effect upon the consummation of the transactions
contemplated by the Merger Agreement, (ii) there shall be any litigation or

Agreement, (B) seeking damages in connection with the consummation of the

invalidate the consummation of transactions contemplated by the Merger
Agreement, or (iii) Lake State shall have determined that any fact, event or
condition exists that, in the judgment of Lake State, would render the Merger
and the other transactions contemplated by the Merger Agreement impractical
because of any state of war, national emergency, banking moratorium or general
suspension of trading on Nasdaq, the New York Stock Exchange, Inc. or other
national securities exchange.

CERTAIN EXPENSES

         The Merger Agreement provides that the parties thereto shall bear
their own expenses incurred in connection with consummating the transactions
contemplated thereby.

RIGHTS OF DISSENT AND APPRAISAL

         A shareholder of Lake State may dissent from the Merger and receive in
cash the appraised value, as of the Effective Time of the Merger, of the shares
of Lake State Common Stock held by such shareholder pursuant





                                       21
<PAGE>   24


to Section 215a of the United States Code (the "Dissent Provisions").  Section
215a of the United States Code is the controlling provision relating to the
dissent rights of Lake State shareholders in light of Section 658.41(2) of the
Florida Banking Code which provides that federal, rather than Florida law, will
be controlling in the merger of a Florida bank into a national bank.  The
appraised value of the Lake State Common Stock may differ from the
consideration that a shareholder of Lake State is entitled to receive in the
Merger.  The following is a summary of the Dissent Provisions, the full text of
which is set forth as Exhibit B to this Proxy Statement/Prospectus.

         Under the Dissent Provisions, a shareholder of Lake State may dissent
from the Merger by (i) voting against the Merger or by giving notice in writing
at or prior to the Special Meeting to Lake State that the shareholder dissents
from the Merger Agreement, and (ii) making a written request to ST-Bank to
receive the fair value of the shares of Lake State Common Stock, which request
is required to be made within thirty days of the Effective Time of the Merger
and to be accompanied by the surrender of the shareholder's stock certificates.

         The value of the shares of any dissenting shareholder shall be
determined as of the Effective Time of the Merger by an appraisal made by a
committee of three persons, composed of one person selected by the holders of
two- thirds of the shares of Lake State Common Stock for which rights of
dissent are being asserted, one selected by the Board of Directors of ST-Bank
and the third selected by the other two.  The valuation agreed upon by any two
of the three appraisers shall govern.  However, if the value so fixed is not
satisfactory to any dissenting shareholder who has requested payment, that
shareholder may, within five days after being notified of the appraised value
of his shares, appeal to the Comptroller of the Currency, who shall cause a
reappraisal to be made which shall be final and binding as to the value of the
shares of the dissenting shareholder who has appealed to the Comptroller.

         If, within ninety days from the Effective Time of the Merger, for any
reason one or more of the three appraisers is not selected as provided by the
Dissent Provisions, or the appraisers shall fail to determine the value of the
shares, the Comptroller shall upon written request of any interested party
cause an appraisal to be made which shall be final and binding on all parties.
In any event, the value of shares ascertained under the Dissent Provisions
shall be promptly paid to the dissenting shareholders by ST-Bank.  In addition,
the SouthTrust Common stock that would have been delivered to the dissenting
shareholders but for their dissent may, if required by law, be sold at an
advertised public auction at which SouthTrust may bid.  If the shares are
auctioned and are sold at a price greater than that paid to the dissenting
shareholders, such excess amount would be remitted to the dissenting
shareholders.  The OCC has taken the position that a shareholder may dissent as
to less than all of the shares of stock owned by such shareholder.  The
expenses of the Comptroller in making the reappraisal or the appraisal, as the
case may be, shall be paid by ST-Bank.

         The foregoing is only a summary of the Dissent Provisions.  The full
text of such provisions is set forth as Exhibit B to this Proxy
Statement/Prospectus and each Lake State shareholder is urged to read these
provisions carefully.

CONDUCT OF BUSINESS BY LAKE STATE PENDING THE MERGER

         The Merger Agreement provides that, until the Effective Time of the
Merger, Lake State shall (i) conduct its business in the usual, regular and
ordinary course consistent with past practice and prudent banking principles,
(ii) use its best efforts to maintain and preserve intact its business
organization, employees, goodwill with customers and advantageous business
relationships and retain the services of its officers and key employees, and
(iii) except as required by law or regulation, take no action which would
adversely affect or delay the ability of Lake State or SouthTrust to obtain any
Consent from any Regulatory Authorities or other approvals required for the
consummation of the transactions contemplated hereby or to perform its
covenants and agreements under the Merger Agreement.

         The Merger Agreement further provides that, until the Effective Time
of the Merger, except as required by law or regulation or contemplated by the
Merger Agreement, Lake State shall not, without the prior written consent of
SouthTrust:

         (i)     change, delete or add any provision of or to the Articles of
                 Incorporation or Bylaws of Lake State;

         (ii)    change the number of shares of the authorized, issued or
                 outstanding capital stock of Lake State, including any

                 reclassification thereof, or issue or grant any option,
                 warrant,

                 State, declare, set aside or pay any dividend or other
                 distribution with respect to the outstanding capital stock of
                 Lake State;

         (iii)   incur any material liabilities or material obligations (other
                 than deposit liabilities and short-term borrowings in the
                 ordinary course of business), whether directly or by way of
                 guaranty, including any obligation for borrowed money, or
                 whether evidenced by any note, bond, debenture, or similar
                 instrument, except in the ordinary course of business
                 consistent with past practice;

         (iv)    make any capital expenditures individually in excess of
                 $10,000, or in the aggregate in excess of $25,000 other than
                 pursuant to binding commitments existing on December 31, 1995
                 and disclosed in a Disclosure Schedule delivered pursuant to
                 Article III of the Merger Agreement or in the annexed Schedule
                 5.1(b)(iv) and other than expenditures necessary to maintain
                 existing assets in good repair;

         (v)     sell, transfer, convey or otherwise dispose of any real
                 property (including "other real estate owned") or interest
                 therein having a book value in excess of or in exchange for
                 consideration in excess of $25,000;

         (vi)    pay any bonuses to any executive officer except pursuant to
                 the terms of an enforceable written employment agreement and
                 except in a manner consistent with past practice, which, in
                 any event, will not exceed an aggregate of $25,000; enter into
                 any new, or amend in any respect any existing, employment,
                 consulting, non-competition or independent contractor
                 agreement with any person; alter the terms of any existing
                 incentive bonus or commission plan; adopt any new or amend in
                 any material respect any existing employee benefit plan,
                 except as may be required by law; grant any general increase
                 in compensation to its employees as a class or to its officers
                 except for non-executive officers in the ordinary course of
                 business and consistent with past practices and policies or

                 agreement; or grant any material increases in fees or other

                 in the ordinary course of business, or (B) acquisitions of

BUSINESS AND MANAGEMENT OF LAKE STATE FOLLOWING THE MERGER; PLANS FOR BUSINESS
OF LAKE STATE

         Upon consummation of the Merger, Lake State will be merged into
ST-Bank, with ST-Bank being the Surviving Corporation in the Merger.  As of the
Effective Time of the Merger, it is anticipated that the Board of Directors of
the Surviving Corporation shall consist of those persons who are serving as
directors of ST-Bank as of the Effective Time of the Merger, and such other
persons as may be designated in writing by SouthTrust at or prior to the
Effective Time of the Merger.  It is further anticipated that the officers of
the Surviving Corporation shall be those persons serving as officers of ST-Bank
as of the Effective Time of the Merger, and such other persons as may be
designated in writing by SouthTrust at or prior to the Effective Time of the
Merger.

         After the Effective Time of the Merger, the present main office of
Lake State will become a full service branch of ST-Bank and the operations of
Lake State will be integrated into the operations of ST-Bank, with efforts
directed toward preserving the existing customer and banking relationships of
Lake State as a part of ST-Bank.


                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

         THE FOLLOWING DISCUSSION IS A SUMMARY OF CERTAIN ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER TO HOLDERS OF LAKE STATE COMMON STOCK WHO
ARE CITIZENS OF THE UNITED STATES.  IT DOES NOT DISCUSS ALL THE TAX
CONSEQUENCES THAT MAY BE RELEVANT TO HOLDERS OF LAKE STATE COMMON STOCK
ENTITLED TO SPECIAL TREATMENT UNDER THE CODE (SUCH AS INSURANCE COMPANIES,
DEALERS IN SECURITIES, TAX-EXEMPT ORGANIZATIONS OR FOREIGN PERSONS) OR TO
HOLDERS OF LAKE STATE COMMON STOCK WHO ACQUIRED THEIR LAKE STATE COMMON STOCK
PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS
COMPENSATION.  THE SUMMARY SET FORTH BELOW DOES NOT PURPORT TO BE A COMPLETE
ANALYSIS OF ALL POTENTIAL TAX EFFECTS OF THE TRANSACTIONS CONTEMPLATED BY THE
MERGER AGREEMENT OR THE MERGER ITSELF.

         EACH HOLDER OF LAKE STATE COMMON STOCK IS URGED TO CONSULT HIS OR HER
OWN TAX AND FINANCIAL ADVISOR AS TO THE EFFECT OF SUCH FEDERAL INCOME TAX
CONSEQUENCES ON HIS OR HER OWN PARTICULAR FACTS AND CIRCUMSTANCES, AND ALSO AS
TO ANY STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES ARISING OUT OF THE
MERGER.

         Neither SouthTrust, ST-Bank, ST-Florida, nor Lake State has requested
or will receive an advance ruling from the Internal Revenue Service ("IRS") as
to any of the federal income tax effects to holders of Lake State Common Stock
of the Merger or of any of the federal income tax effects to SouthTrust,
ST-Bank, ST-Florida or Lake State of the Merger.  Instead, Lake State will rely
upon an opinion of Bradley, Arant, Rose & White as to the federal income tax
consequences of the Merger to the holders of Lake State Common Stock.  The
opinion of Bradley, Arant, Rose & White is based entirely upon the Code,
regulations now in effect thereunder, current administrative rulings and
practice, and judicial authority, all of which are subject to change.  Unlike a
ruling from the IRS, an opinion is not binding on the IRS and there can be no
assurance, and none is hereby given, that the IRS will not take a position
contrary to one or more positions reflected herein or that the opinion will be
upheld by the courts if challenged by the IRS.

         In the opinion of Bradley, Arant, Rose & White, which opinion is based
upon various representations and subject to various assumptions and
qualifications, the following federal income tax consequences to the holders of
Lake State Common Stock will result from the Merger:

         (i)     For federal income tax purposes the Merger will be viewed as
                 an acquisition by ST-Florida of substantially all of the
                 assets of Lake State solely in exchange for SouthTrust Common
                 Stock and the assumption of all the liabilities of Lake State
                 by ST-Florida, followed by the transfer of the assets of Lake
                 State to ST-Bank and the assumption by ST-Bank of the
                 liabilities of Lake State.

         (ii)    The acquisition by ST-Florida of substantially all of the
                 assets of Lake State in exchange solely for shares of
                 SouthTrust Common Stock and the assumption by ST-Florida of
                 Lake State's liabilities, as described above, will constitute
                 a reorganization within the meaning of section 368(a)(1)(C) of
                 the Code.  Pursuant to Section 368(a)(2)(C) of the Code, the
                 acquisition by ST-Florida of substantially all of the assets
                 of Lake State will not be disqualified under Section
                 368(a)(1)(C) of the Code solely by reason of the fact that the
                 assets of Lake State that were





                                       24
<PAGE>   27


                 acquired by ST-Florida are transferred to ST-Bank.
                 SouthTrust, ST-Florida and Lake State each will be a "party to
                 a reorganization" within the meaning of Section 368(b) of the
                 Code.

         (iii)   No gain or loss will be recognized by the shareholders of Lake
                 State upon the receipt of SouthTrust Common Stock solely in
                 exchange for their shares of Lake State Common Stock.

         (iv)    The basis of the SouthTrust Common Stock to be received by the
                 Lake State shareholders (including any fractional share
                 interest to which they may be entitled) will be the same as
                 the basis of the Lake State Common Stock surrendered in the
                 exchange.

         (v)     The holding period of the shares of SouthTrust Common Stock
                 (including any fractional share interests to which they may be
                 entitled) received by the shareholders of Lake State will
                 include the period during which the Lake State Common Stock
                 surrendered in exchange therefor was held, provided that the
                 shares of Lake State Common Stock were held as capital assets
                 within the meaning of Section 1221 of the Code as of the
                 Effective Time of the Merger.

         (vi)    Lake State shareholders who exercise dissenters' rights, and
                 as a result of which receive only cash, will be treated as
                 having received such cash as a distribution in redemption of
                 their Lake State Common Stock, subject to the provisions and
                 limitations of Section 302 of the Code.

         (vii)   The payment of cash to a Lake State shareholder in lieu of
                 issuing a fractional share interest in SouthTrust Common Stock
                 will be treated for federal income tax purposes as if the
                 fractional share actually was issued as part of the Merger and
                 then was redeemed by SouthTrust.  This cash payment will be
                 treated as having been received as a distribution in full
                 payment in exchange for the stock redeemed as provided in
                 Section 302(a) of the Code, provided that such redemption is
                 not essentially equivalent to a dividend.

         The opinion of Bradley, Arant, Rose & White is rendered solely with
respect to certain federal income tax consequences of the Merger under the
Code, and does not extend to the income or other tax consequences of the Merger
under the laws of any State or any political subdivision of any State; nor does
it extend to any tax effects or consequences of the Merger to SouthTrust,
ST-Florida or ST-Bank other than those expressly stated  in the opinion.
Furthermore, no opinion is expressed as to the federal or state tax treatment
of the transaction under any other provisions of the Code and regulations, or
about the tax treatment of any conditions existing at the time of, or effects
resulting from, the transaction that are not specifically covered by the
opinion.

As of March 31, 1996, 95,486,470 shares of SouthTrust Common Stock were issued
and outstanding, exclusive of shares held as treasury stock, and no shares of
SouthTrust Preferred Stock were outstanding.  In addition, 500,000 shares of
SouthTrust Preferred Stock designated as Series A Junior Participating
Preferred Stock were reserved for issuance upon the exercise of certain rights
described below under "SouthTrust Common Stock--Stockholder Rights Plan."

         Since SouthTrust is a holding company, the right of SouthTrust, and
hence the right of creditors and stockholders of SouthTrust, to participate in
any distribution of assets of any subsidiary (including SouthTrust Bank of
Alabama, N.A.) upon its liquidation or reorganization or otherwise is
necessarily subject to the prior claims of creditors of the subsidiary, except
to the extent that claims of SouthTrust itself as a creditor of the subsidiary
may be recognized.

         The following summary does not purport to be complete and is subject
in all respects to the applicable provisions of the General Corporation Law of
the State of Delaware and SouthTrust's Restated Certificate of Incorporation,
including the Certificate of Designation describing the Series A Junior
Participating Preferred Stock.

SOUTHTRUST COMMON STOCK

  Dividend Rights

         Holders of SouthTrust Common Stock are entitled to dividends when, as
and if declared by SouthTrust's Board of Directors out of funds legally
available therefor.  Under Delaware law, SouthTrust may pay dividends out of
surplus (whether capital surplus or earned surplus) or net profits for the
fiscal year in which declared or for the preceding fiscal year, even if its
surplus accounts are in a deficit position.  The sources of funds for payment
of dividends by SouthTrust are its subsidiaries.  Because its primary
subsidiaries are banks, payments made by such subsidiaries to SouthTrust are
limited by law and regulations of the bank regulatory authorities.  See "MARKET
AND DIVIDEND INFORMATION RESPECTING THE COMMON STOCK OF SOUTHTRUST AND LAKE
STATE."

  Voting Rights and Other Matters

         The holders of SouthTrust Common Stock are entitled to one vote per
share on all matters brought before the stockholders.  The holders of
SouthTrust Common Stock do not have the right to cumulate their shares of
SouthTrust Common Stock in the election of directors.  SouthTrust's Restated
Certificate of Incorporation provides that in the event of a transaction or a
series of transactions with an "Interested Stockholder" (generally defined as a
holder of more than 10% of the voting stock of SouthTrust or an affiliate of
such a holder) pursuant to which SouthTrust would be merged into or with
another corporation or securities of SouthTrust would be issued in a
transaction which would permit control of SouthTrust to pass to another entity,
or similar transactions having the same effect, approval of such transactions
requires the vote of the holders of 70% of the voting power of the outstanding
voting securities of SouthTrust, except in cases in which either certain price
criteria and procedural requirements are satisfied or the transaction is
recommended to the stockholders by a majority of the members of SouthTrust's
Board of Directors who are unaffiliated with the Interested Stockholder and who
were directors before the Interested Stockholder became an Interested
Stockholder.

         Holders of SouthTrust Common Stock are not entitled to any preemptive
rights to subscribe for any additional securities which may be issued.

  Liquidation Rights

         In the event of liquidation, holders of the SouthTrust Common Stock
will be entitled to receive pro rata any assets distributable to stockholders
with respect to the shares held by them, after payment of indebtedness and such
preferential amounts as may be required to be paid to the holders of any
SouthTrust Preferred Stock hereafter issued by SouthTrust.

  Provisions with Respect to Board of Directors

         SouthTrust's Restated Certificate of Incorporation provides that the
members of SouthTrust's Board of Directors are divided into three classes as
nearly equal in number as possible.  Each class is elected for a three-year
term.  At each annual meeting of stockholders of SouthTrust, one-third of the
members of SouthTrust's Board of Directors will be elected for a three-year
term, and the other directors will remain in office until their three-year
terms expire.  Therefore, control of SouthTrust's Board of Directors cannot be
changed in one year, and at least two annual meetings must be held before a
majority of the members of SouthTrust's Board of Directors can be changed.

  Special Vote Requirements for Certain Amendments to Restated Certificate of
Incorporation

         The General Corporation Law of the State of Delaware and the Restated
Certificate of Incorporation and Bylaws of SouthTrust provide that, because the
Board of Directors of SouthTrust is classified, a director, or SouthTrust's
entire Board of Directors, may be removed by the stockholders only for cause.
The Restated Certificate of Incorporation and Bylaws of SouthTrust also provide
that the affirmative vote of the holders of at least 70% of the voting power of
the outstanding capital stock entitled to vote for the election of directors is
required to remove a director or the entire Board of Directors from office.
Certain portions of the Restated Certificate of Incorporation of SouthTrust
described in certain of the preceding paragraphs, including those related to
business





                                       26
<PAGE>   29


combinations and the classified Board of Directors, may be amended only by the
affirmative vote of the holders of 70% of the voting power of the outstanding
voting stock of SouthTrust.

  Possible Effects of Special Provisions

         Certain of the provisions contained in the Restated Certificate of
Incorporation and Bylaws of SouthTrust described above have the effect of
making it more difficult to change SouthTrust's Board of Directors, and may
make SouthTrust's Board of Directors less responsive to stockholder control.
These provisions also may tend to discourage attempts by third parties to
acquire SouthTrust because of the additional time and expense involved and a
greater possibility of failure, and, as a result, may adversely affect the
price that a potential purchaser would be willing to pay for the capital stock
of SouthTrust, thereby reducing the amount a stockholder might realize in, for
example, a tender offer for the capital stock of SouthTrust.

  Stockholder Rights Plan

         On February 22, 1989, the Board of Directors of SouthTrust declared a
dividend to holders of SouthTrust Common Stock of record on March 6, 1989 (the
"Record Date") of one right (a "Right"; collectively, the "Rights") for, and to
be attached to, each share of SouthTrust Common Stock outstanding on the Record
Date.  Each Right entitles the holder thereof to purchase from SouthTrust one
one-hundredth of a share of SouthTrust Preferred Stock designated as the Series
A Junior Participating Preferred Stock ("Series A Preferred Stock") at a
purchase price of $75.00 (the "Purchase Price").  Such resolutions also provide
that as long as the Rights are attached to shares of SouthTrust Common Stock as
provided in the Rights Agreement referred to below, the appropriate number of
Rights shall be issued with each share of SouthTrust Common Stock issued after
March 6, 1989.  The number of Rights attached to or to be issued with each
share of SouthTrust Common Stock as well as the redemption price for each such
Right, were appropriately decreased as a result of a three-for-two stock split
effected by SouthTrust on January 24, 1992, and a three-for-two stock split
effected by SouthTrust on May 19, 1993.  Accordingly, at the present time
four-ninths of a Right is attached to each share of SouthTrust Common Stock and
four-ninths of a right will be issued with each share of SouthTrust Common
Stock exchanged in the merger for Lake State Common Stock.

         The Rights will expire on February 22, 1999 unless redeemed earlier
and will not be exercisable or transferable separately from the shares of
SouthTrust Common Stock until the close of business on the Distribution Date,
which will occur on the earlier of (i) the tenth day following a public
announcement that a person (an "Acquiring Person") or any associate or
affiliate of an Acquiring Person has acquired, or obtained the right to
acquire, beneficial ownership of 20% or more of the outstanding SouthTrust
Common Stock (the "Stock Acquisition Date"); or (ii) the tenth day following
commencement of a tender or exchange offer which would result in the ownership
of 20% or more of the outstanding SouthTrust Common Stock; or (iii) the tenth
day after SouthTrust's Board of Directors declares, upon a determination by at
least a majority of SouthTrust's Disinterested Directors, that a person, alone
or with affiliates and associates (an "Adverse Person"), has become the
beneficial owner of a substantial amount (not to be less than 10%) of
outstanding SouthTrust Common Stock and that such person's ownership either is
intended to cause SouthTrust to take action adverse to its long-term interests
or may cause a material adverse impact on SouthTrust to the detriment of
SouthTrust's stockholders.

         In the event that (i) SouthTrust's Board of Directors determines that
a person is an Adverse Person; (ii) SouthTrust is the surviving corporation in
a merger with an Acquiring Person and SouthTrust's Common Stock remains
outstanding and unchanged and is not exchanged for securities of the Acquiring
Person or other property; (iii) an Acquiring Person receives a financial
benefit or advantage, through certain self-dealing transactions involving
SouthTrust, greater than that received by other stockholders of SouthTrust or
that which would have resulted from arms-length negotiations; (iv) a person
becomes the beneficial owner of 30% or more of the outstanding SouthTrust
Common Stock (except pursuant to a "Fair Offer" as determined by the
Disinterested Directors); or (v) while there is an Acquiring Person, an event
involving SouthTrust or any of its subsidiaries occurs which results in the
Acquiring Person's proportionate ownership interest being increased by more
than 1%, each holder of a Right will have the right to receive, upon payment of
the Purchase Price, in lieu of Series A Preferred Stock, a number of shares of
SouthTrust Common Stock (or, in certain circumstances, cash or other property)
having a value equal to twice the Purchase Price.  Rights are not exercisable
following the occurrence of any of the events set forth in this paragraph until
the expiration of the period during which the Rights may be redeemed by
SouthTrust as described below.  Notwithstanding the foregoing, after the
occurrence of any of the events set forth in this paragraph, Rights that are
(or, under certain circumstances, Rights that were) beneficially owned by an
Acquiring Person or an Adverse Person will be null and void.





                                       27
<PAGE>   30


         Unless the Rights are redeemed earlier, if, after the Distribution
Date, SouthTrust is acquired in a merger or other business combination in which
SouthTrust is not the surviving corporation or in which SouthTrust Common Stock
is changed into or exchanged for securities of any other person or other
property (other than a merger which follows a Fair Offer) or 50% or more of the
assets or earning power of SouthTrust and its subsidiaries (taken as a whole)
are sold or transferred, the Rights Agreement provides that each holder of
record of a Right will from and after that time have the right to receive, upon
payment of the Purchase Price, that number of shares of common stock of the
acquiring company which has value equal to twice the Purchase Price.

         At any time until ten days following the Stock Acquisition Date
(subject to certain provisions requiring action by a majority of the
Disinterested Directors, as defined in the Rights Agreement), SouthTrust may
redeem the Rights in whole, but not in part, at a price of $0.01 per Right.
Prior to the Distribution Date, SouthTrust may, except with respect to the
Purchase Price, redemption price or date of expiration of the Rights, amend the
Rights in any manner.  At any time after the Distribution Date, SouthTrust may
amend the Rights in any manner that does not adversely affect the interest of
holders of the Rights as such.

         The Rights have certain anti-takeover effects and may adversely affect
a third party's attempt to acquire SouthTrust.  The Rights will cause
substantial dilution to a person or group that attempts to acquire SouthTrust.
The Rights should not interfere with any merger or other business combination
approved by SouthTrust's Board of Directors since, among other things, the
Board of Directors may, at its option, under certain circumstances, redeem all
but not less than all of the then outstanding Rights at the redemption price,
as discussed below.

         The foregoing description of the Rights and the Series A Preferred
Stock does not purport to be complete and is qualified in its entirety by
reference to the Rights Agreement between SouthTrust and Mellon Bank, N.A., as
Rights Agent, and the Certificate of Designation for the Series A Preferred
Stock, copies of each of which are filed as exhibits to the Registration
Statement of which this Proxy Statement/Prospectus forms a part.

  Transfer Agent

         The transfer agent for SouthTrust Common Stock is Chemical Mellon
Shareholder Services, L.L.C.

SOUTHTRUST PREFERRED STOCK

  General

         Under SouthTrust's Restated Certificate of Incorporation, the Board of
Directors is authorized without further stockholder action to provide for the
issuance of up to 5,000,000 shares of SouthTrust Preferred Stock, in one or
more series, by adoption of a resolution or resolutions providing for the
issuance of such series and determining the relative rights and preferences of
the shares of any such series with respect to the rate of dividend, call
provisions, payments on liquidation, sinking fund provisions, conversion
privileges and voting rights and whether the shares shall be cumulative,
non-cumulative or partially cumulative.  The holders of SouthTrust Preferred
Stock would not have any preemptive right to subscribe for any shares issued by
SouthTrust.  It is not possible to state the actual effect of the authorization
and issuance of SouthTrust Preferred Stock upon the rights of holders of
SouthTrust Common Stock unless and until SouthTrust's Board of Directors
determines the price and specific rights of the holders of a series of
SouthTrust Preferred Stock.  Such effects might include, however, (i)
restrictions on dividends on SouthTrust Common Stock if dividends on SouthTrust
Preferred Stock have not been paid; (ii) dilution of the voting power of
SouthTrust Common Stock to the extent that SouthTrust Preferred Stock has
voting rights, or that any SouthTrust Preferred Stock series is convertible
into SouthTrust Common Stock; (iii) dilution of the equity interest of
SouthTrust Common Stock unless the SouthTrust Preferred Stock is redeemed by
SouthTrust; and (iv) SouthTrust Common Stock not being entitled to share in
SouthTrust's assets upon liquidation until satisfaction of any liquidation
preference granted SouthTrust Preferred Stock.  While the ability of SouthTrust
to issue SouthTrust Preferred Stock is, in the judgment of SouthTrust's Board
of Directors, desirable in order to provide flexibility in connection with
possible acquisitions and other corporate purposes, its issuance could impede
an attempt by a third party to acquire a majority of the outstanding voting
stock of SouthTrust.

  Series A Junior Participating Preferred Stock

         In connection with the adoption of the Stockholder Rights Plan
described above, SouthTrust's Board of Directors designated 500,000 shares of
SouthTrust's authorized but unissued SouthTrust Preferred Stock as Series A





                                       28
<PAGE>   31


Junior Participating Preferred Stock (which has been previously referred to as
the "Series A Preferred Stock").  The terms of the Series A Preferred Stock are
such that one share of Series A Preferred Stock will be approximately
equivalent in terms of dividend and voting rights, before adjustment for the
three-for-two stock split effective on January 24, 1992 and a further
three-for-two stock split effective on May 19, 1993, to 100 shares of
SouthTrust Common Stock.  No shares of Series A Preferred Stock have been
issued as of the date of this Proxy Statement/Prospectus.

              Shares of Lake State Common Stock are not actively traded, and
such trading activity, as it occurs, takes place in privately negotiated
transactions.  During the last two years, the sales price of shares of Lake
State Common Stock of which Lake State had knowledge ranged from $11.00 to
$13.00 per share.  The last sale of Lake State Common Stock of which Lake State
had knowledge occurred in December, 1995, at a price of $13.00 per share.

$26.00 and $25.875, respectively; and on May 28, 1996, the last sales price of
SouthTrust Common Stock as obtained from Nasdaq was $27.50.

DIVIDENDS

              On January 3, 1995 Lake State paid its first annual dividend of
$0.40 per share for the year ended December 31, 1994.  On December 14, 1995 a
cash dividend was declared of $0.55 per share for the year ended December 31,
1995, payable on January 2, 1996.  Pursuant to the Merger Agreement, Lake State
may not declare, set aside or pay any dividend during the pendency of the
Merger Agreement.  If the Merger Agreement is terminated, Lake State intends to
continue to pay dividends in a manner generally consistent with its recent past
practice.  As discussed below, the payment of dividends by a Florida banking
corporation such as Lake State, are subject to various regulatory restrictions
and, in any event, are declared and paid in the discretion of the Board of
Directors of Lake State.  See "COMPARISON OF THE COMMON STOCK OF SOUTHTRUST AND
LAKE STATE - Dividends."  The following table sets forth the cash dividends per
share declared on SouthTrust Common Stock during the periods indicated:

</TABLE>

         Dividends paid by SouthTrust on the SouthTrust Common Stock are at the
discretion of SouthTrust's Board of Directors and depend upon the restrictions
on the payment of dividends by banks as described below, SouthTrust's earnings
and financial condition and other relevant factors.  The current policy of
SouthTrust is to pay dividends on a quarterly basis.  Subject to an evaluation
of its earnings and financial condition and other factors, including the
restrictions on the payment of dividends by banks described below, SouthTrust
anticipates that it will continue to pay regular quarterly dividends with
respect to the SouthTrust Common Stock.

         There are certain limitations on the payment of dividends to
SouthTrust by its subsidiary banks.  The amount of dividends that each
subsidiary national bank of SouthTrust may declare in one year, without
approval of the Office of the Comptroller of the Currency (the "OCC"), is the
sum of the bank's net profits for that year and its retained net profits for
the preceding two years.  Under the rules of the OCC, the calculation of net
profits is more restrictive under certain circumstances.  The banking
authorities in the states where SouthTrust owns state-chartered banks also
regulate the payment of dividends by banks organized in such states.  Under the
Alabama Banking Code, a state bank may not declare or pay a dividend in excess
of 90% of the net earnings of such bank until the surplus of the bank is equal
to at least 20% of its capital, and thereafter the prior written approval of
the Superintendent of Banks is required if the total of all dividends declared
by the bank in any calendar year exceeds the total of its net earnings for that
year combined with its retained net earnings for the preceding two years.  No
dividends, withdrawals or transfers may be made from the bank's surplus without
prior written approval of the Superintendent of Banks.

         Under the Florida Financial Institutions Code, a state bank may not
declare or pay a dividend at any time which its net income from the current
year combined with the retained net income from the preceding two years is a
loss or which would cause the capital accounts of the bank to fall below the
minimum amount required by state and federal banking laws and regulations.

         Under the Financial Institutions Code of Georgia, a bank may not pay
dividends when it is insolvent, or would be rendered insolvent, and dividends
may only be paid out of retained earnings and when the bank has paid-in capital
and appropriated retained earnings, in combination equal to at least 20% of its
capital stock.

         Under the North Carolina Banking Code, a state chartered bank with
common stock in excess of $15,000 may not declare a dividend until the surplus
is equal to at least 50% of the amount of common stock.

         The South Carolina Banking Code provides that, before a state
chartered bank can pay a dividend, approval must be obtained from the South
Carolina Commissioner of Banking.

         Under the Tennessee Banking Code, a state bank may not declare
dividends in excess of 90% of the net earnings during the past year until the
surplus is equal to the amount of common stock.

<PAGE>   33


         The Mississippi Banking Code provides that no state bank may declare
or pay any dividend upon its common stock unless it has received the written
approval of the Commissioner of Banking and Consumer Finance.

         Under the foregoing laws and regulations, at December 31, 1995,
approximately $332.8 million was available for payment of dividends to
SouthTrust by its bank subsidiaries.

SHAREHOLDERS

         As of December 31, 1995, there were approximately 190 holders of
record of Lake State Common Stock.

         The rights of Lake State's shareholders are governed by the Articles

rights of Lake State's shareholders who become SouthTrust shareholders will be
governed by the laws of the State of Delaware and by SouthTrust's Restated
Certificate of Incorporation and Bylaws.  The following summary of the rights
of the holders of shares of SouthTrust Common Stock and the holders of shares
of Lake State Common Stock is qualified in its entirety by reference to the
Restated Certificate of Incorporation and Bylaws of SouthTrust, the Articles of
Incorporation and Bylaws of Lake State, the General Corporation Law of the
State of Delaware, the Florida Financial Institutions Code and the Florida
Business Corporation Act.

DIVIDENDS

         The sources of funds for payments of dividends by SouthTrust are its
subsidiaries.  Because Lake State and the primary subsidiaries of SouthTrust
are financial institutions, payments made by such subsidiaries to SouthTrust
and by Lake State to its shareholders are limited by law and regulations of the
bank regulatory authorities.  See "DESCRIPTION OF SOUTHTRUST CAPITAL
STOCK--SouthTrust Common Stock--Dividend Rights" and "MARKET AND DIVIDEND
INFORMATION RESPECTING THE COMMON STOCK OF SOUTHTRUST AND LAKE
STATE--Dividends" for information concerning the effect of such limitations on
SouthTrust's and Lake State's ability to pay dividends.  The General
Corporation Law of the State of Delaware provides that, subject to any
restrictions in the corporation's certificate of incorporation, dividends may
be declared from the corporation's surplus or, if there is no surplus, from its
net profits for the fiscal year in which the dividend is declared and the
preceding fiscal year.  Dividends may not be declared, however, if the
corporation's capital has been diminished to an amount less than the aggregate
amount of all capital represented by the issued and outstanding stock of all
classes having a preference upon the distribution of assets.  The Florida
Financial Institutions Code provides that a Florida banking corporation may
declare dividends equal to the net profits of the period to which such
dividends relate plus its retained net profits of the preceding two years.
Further, with the approval of the Florida Department, a bank may declare a
dividend from retained net profits which accrued prior to the preceding two
years.  Notwithstanding the foregoing, at least 20% of the bank's net profits
must be carried over to the bank's surplus fund until the surplus fund shall
equal at least the amount of its common and preferred stock then issued and
outstanding.  In any event, no bank may declare any dividend at a time at which
its net income for the current year, combined with the retained net income for
the preceding two years, is a loss or which would cause the capital accounts of
the bank to fall below the minimum amounts required by state or federal law.

VOTING RIGHTS AND OTHER MATTERS

         The holders of shares of Lake State Common Stock and the holders of
shares of SouthTrust Common Stock are each entitled to one vote per share on
all matters brought before the shareholders.  The holders of the shares of
SouthTrust Common Stock and Lake State Common Stock do not have the right to
cumulate their votes in the election of directors.





                                       31

         The Restated Certificate of Incorporation of SouthTrust provides that
in the event of a transaction or a series of transactions with an Interested
Stockholder (generally defined as a holder of more than 10% of the voting stock
of SouthTrust or an affiliate of such a holder) pursuant to which SouthTrust
would be merged into or with another corporation or securities of SouthTrust
would be issued in a transaction which would permit control of SouthTrust to
pass to another entity, or similar transactions having the same effect,
approval of such transaction requires the vote of the holders of 70% of the
outstanding voting securities of SouthTrust, except in cases in which either
certain price criteria and procedural requirements are satisfied or the
transaction is recommended to the shareholders by a majority of the members of
the Board of Directors of SouthTrust who are unaffiliated with the Interested
Stockholder and who were directors before the Interested Stockholder became an
Interested Stockholder.

         SouthTrust is subject to Section 203 of the Delaware General
Corporation Law.  That section generally provides that a corporation may not
engage in a business combination, except with extraordinary corporate approval,
with any person deemed to be an "interested stockholder" for a period of three
years following the date that the stockholder became an interested stockholder.
An "interested stockholder" is defined as any person who directly or indirectly
owns 15% or more of the outstanding voting stock of the corporation within the
three-year period beginning immediately prior to the date on which such
determination is made.  The extraordinary corporate approval must consist of
board approval prior to the time the person became an interested stockholder or
approval of the transaction by the board of directors and at least two-thirds
of the outstanding voting stock which is not owned by the interested
stockholder; in the absence of such approval, the interested stockholder must
own at least 85% of the voting stock of the corporation.

         Section 607.0901 of the Florida Business Corporation Act is a similar
provision.  It provides that an affiliated transaction must be approved by,
subject to certain exceptions, the vote of the holders of two-thirds of the
voting shares of the Florida corporation other than those beneficially owned by
an interested shareholder.  An affiliated transaction includes any merger with
an interested shareholder or any corporation which is an affiliate of the
interested shareholder, any significant sale or mortgage of assets of the
corporation to the interested shareholder and other transactions of similar
effect.  The Florida provision defines an interested stockholder as a
beneficial owner of 10% or more of the outstanding voting shares of the
corporation.  Because Lake State has fewer than 300 shareholders the provision
is not applicable to it.  In any event, the provision is not applicable to the
Merger because ST-Bank is not an "interested shareholder".

         In addition, Florida Business Corporation Act Section 607.0902 limits
the ability of persons to acquire prescribed amounts of voting securities of
issuing public corporations, such as Lake State.  The statute provides that any
person who proposes to make a control share acquisition must follow certain
procedures, including giving notice of the intent to acquire stock and calling
a meeting of shareholders at which such acquisition must be approved by
resolution of a majority of shareholders of each class entitled to vote
thereon.  Otherwise, the acquired control shares shall be divested of voting
rights and shall be subject to redemption, if so provided in the articles of
incorporation or bylaws of the corporation.  In addition, those shareholders
not voting in favor of a control share acquisition may exercise rights of
dissent.  For purposes of this statute, a "control share acquisition" means the
acquisition, directly or indirectly, by any person of as few as one-fifth of
all voting power of the corporation, subject to certain exceptions.  No similar
provision exists under the General Corporation Law of the State of Delaware or,
to the knowledge of SouthTrust, is otherwise applicable to SouthTrust Common
Stock.  The Florida control share provision is not applicable to the Merger
because it is a merger and because the Merger has been approved by the Board of
Directors of Lake State.

         The effect of the business combination and affiliated transactions
provisions, respectively, is to make more difficult the acquisition of majority
control of a corporation for the use of its assets to finance such acquisition.
The Florida control share statute which is applicable to Lake State discourages
tender offers for stock where the purpose of such tender offers is to obtain
voting control of the corporation.

         The Bylaws of SouthTrust provide that the members of the Board of
Directors are to be divided into three classes, which classes are as nearly
equal in number as possible.  Each class has been elected for a three-year
term.  At each annual meeting of shareholders, one-third of the members of the
Board of Directors will be elected for a three- year term, and the other
directors will remain in office.  Therefore, control of the Board of Directors
cannot be changed in one year, and at least two annual meetings must be held
before a majority of the members of the Board of Directors can be changed.  But
for this provision in the Bylaws, all directors would stand for election at
each annual meeting. The Bylaws of Lake State provide that the Board of
Directors of Lake State shall hold one-year terms and shall be elected annually
at a meeting of the shareholders called for such purpose.





                                       32
<PAGE>   35


         Both Delaware and Florida law provide (unless otherwise provided in a
corporation's charter or bylaws), that a director, or the entire Board of
Directors, may be removed by the stockholders with or without cause by vote of
the holders of a majority of the shares of capital stock of the corporation
then entitled to vote on the election of directors.  The Restated Certificate
of Incorporation and Bylaws of SouthTrust provide, however, that the
affirmative vote of the holders of at least 70% of the voting power of the
outstanding capital stock entitled to vote for the election of directors is
required to remove a director or the entire Board of Directors from office and
such removal may be effected only for cause.  Under both the Restated
Certificate of Incorporation of SouthTrust and the Articles of Incorporation of
Lake State, any vacancy created by such removal shall then be filled by a
majority vote of the directors then in office and the successor director so
elected shall fill the unexpired term of the director removed from office.

         The Bylaws of both SouthTrust and Lake State also provide that
vacancies on the Board of Directors caused by the death or resignation of a
director or the creation of a new directorship may be filled by the remaining
directors.  A person selected by the remaining directors to fill a vacancy will
serve until the annual meeting of shareholders at which the term of the class
of directors to which he has been appointed expires.  Therefore, in the case of
SouthTrust if a director who was recently elected to a three-year term resigns,
the remaining directors will be able to select a person to serve the remainder
of that three-year term, and such person will not be required to stand for
election until the third annual meeting of stockholders after his appointment.

         Under the General Corporation Law of the State of Delaware (unless
otherwise provided in the certificate of incorporation), any action required or
permitted to be taken by the stockholders of a corporation may be taken without
a meeting and without a stockholder vote if a written consent is signed by the
holders of the shares of outstanding stock having the requisite number of votes
that would be necessary to authorize such action at a meeting of stockholders
at which all shares entitled to vote thereon were present and voted.  Under the
Restated Certificate of Incorporation of SouthTrust, action by the written
consent of the stockholders is prohibited.  Further, under the Restated
Certificate of Incorporation and Bylaws of SouthTrust, the stockholders are not
permitted to call a special meeting of stockholders or to require that the
Board of Directors call such a meeting.  Under the Florida Business Corporation
Act, any action required or permitted to be taken by the shareholders of a
corporation may be taken without a meeting and without a shareholder vote if a
written consent is signed by the holders of the percentage of outstanding
capital stock necessary to take such action thereto.  Under the Bylaws of Lake
State, any action taken by the Board of Directors without a meeting is a valid
action if either before or after such action is taken, all members of the Board
sign a written consent as to such action.

         The portions of the Restated Certificate of Incorporation of
SouthTrust described in certain of the preceding paragraphs may be amended only
by the affirmative vote of the holders of 70% of the outstanding voting stock
of SouthTrust.  The Bylaws of Lake State may be amended by a vote of the
majority of the Board of Directors or by the shareholders of Lake State.

         The provisions contained in the Restated Certificate of Incorporation
and Bylaws of SouthTrust described above have the effect of making it more
difficult to change the Board of Directors, and may make the Board of Directors
less responsive to shareholder control.  Those provisions also may tend to
discourage attempts by third parties to acquire SouthTrust because of the
additional time and expense involved and a greater possibility of failure.
This also can affect the price that a potential purchaser would be willing to
pay for the stock of SouthTrust, thereby reducing the amount a stockholder
might realize in, for example, a tender offer for the stock of SouthTrust.

RIGHTS ON LIQUIDATION

         In the event of liquidation, the holders of SouthTrust Common Stock
and the holders of Lake State Common Stock will be entitled to receive pro rata
any assets distributable to shareholders with respect to the shares held by
them, after payment of indebtedness and such preferential amounts as may be
required to be paid to the holders of any preferred stock presently outstanding
or hereafter issued by either corporation.

PREEMPTIVE RIGHTS

         The holders of SouthTrust Common Stock and Lake State Common Stock do
not have any preemptive rights to purchase additional shares of any class of
securities, including common stock, of SouthTrust or Lake State, respectively,
which may hereafter be issued.

REPORTS TO STOCKHOLDERS

         The SouthTrust Common Stock is registered under the Exchange Act, and,
therefore, SouthTrust is required to provide annual reports containing audited
financial statements to shareholders and to file other reports with the
Commission and solicit proxies in accordance with the rules of the Commission.
SouthTrust also provides reports to its shareholders on an interim basis
containing unaudited financial information.

         The Lake State Common Stock is not registered under the Exchange Act.
Lake State provides its shareholders with annual reports containing audited
financial statements of Lake State.  In addition, Lake State regularly files
reports with the FDIC and the Florida Department, certain of which may be
inspected by the public.

STOCKHOLDERS' RIGHTS PLAN

         As described above under the caption "DESCRIPTION OF SOUTHTRUST
CAPITAL STOCK - SouthTrust Common Stock - Stockholder Rights Plan," presently
attached to each share of SouthTrust Common Stock is four-ninths of a Right
issued pursuant to the Rights Agreement described under such caption.


                           SUPERVISION AND REGULATION


  Bank Holding Company Regulation

         SouthTrust is a bank holding company within the meaning of the Bank
Holding Company Act of 1956, as amended (the "Holding Company Act"), and is
registered with the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board").  SouthTrust's banking subsidiaries are subject to
restrictions under federal law which limit the transfer of funds by the
subsidiary banks to their respective holding companies and nonbanking
subsidiaries, whether in the form of loans, extensions of credit, investments
or asset purchases.  Such transfers by any subsidiary bank to its holding
company or any non-banking subsidiary are limited in amount to 10% of the
subsidiary bank's capital and surplus and, with respect to SouthTrust and all
such nonbanking subsidiaries, to an aggregate of 20% of such bank's capital and
surplus.  Furthermore, such loans and extensions of credit are required to be
secured in specified amounts.  The Holding Company Act also prohibits, subject
to certain exceptions, a bank holding company from engaging in or acquiring
direct or indirect control of more than 5% of the voting stock of any company
engaged in non-banking activities.  An exception to this prohibition is for
activities expressly found by the Federal Reserve Board to be so closely
related to banking or managing or controlling banks as to be a proper incident
thereto.

         As a bank holding company, SouthTrust is required to file with the
Federal Reserve Board semi-annual reports and such additional information as
the Federal Reserve Board may require.  The Federal Reserve Board may also make
examinations of SouthTrust and each of its subsidiaries.

         According to Federal Reserve Board policy, bank holding companies are
expected to act as a source of financial strength to each subsidiary bank and
to commit resources to support each such subsidiary.  This support may be
required at times when a bank holding company may not be able to provide such
support.  Furthermore, in the event of a loss suffered or anticipated by the
FDIC -- either as a result of default of a banking or thrift subsidiary of
SouthTrust or related to FDIC assistance provided to a subsidiary in danger of
default -- the other banking subsidiaries of SouthTrust may be assessed for the
FDIC's loss, subject to certain exceptions.

         Various federal and state statutory provisions limit the amount of
dividends the subsidiary banks can pay to their holding companies without
regulatory approval.  The approval of the OCC is required for any dividend by a
national bank to its holding company if the total of all dividends declared by
such bank in any calendar year would exceed the total of its net profits, as
defined by the OCC, for that year combined with its retained net profits for
the preceding two years less any required transfers to surplus or a fund for
the retirement of any preferred stock.  Comparable prohibitions on the
declaration of dividends are imposed by the Alabama Banking Code, the Florida
Financial Institutions Code, the North Carolina Banking Code, the South
Carolina Banking Code, the Tennessee Banking Code and the Financial
Institutions Code of Georgia.  In addition, a national bank may not pay a
dividend in an amount greater than its net profits then on hand after deducting
its loan losses and bad debts.  For this purpose, bad debts are defined to
include, generally, the principal amount of loans which are in arrears with
respect





                                       34
<PAGE>   37


to interest by six months or more or are past due as to payment of principal
(in each case to the extent that such debts are in excess of the reserve for
possible credit losses).  Under the foregoing laws and regulations, at December
31, 1995, approximately $332.8 million was available for payment of dividends
to SouthTrust by its bank subsidiaries.  The payment of dividends by any bank
also may be affected by other factors, such as the maintenance of adequate
capital for such subsidiary bank.  In addition to the foregoing restrictions,
the Federal Reserve Board has the power to prohibit dividends by bank holding
companies if their actions constitute unsafe or unsound practices.  The Federal
Reserve Board has issued a policy statement on the payment of cash dividends by
bank holding companies, which expresses the Federal Reserve Board's view that a
bank holding company experiencing earnings weaknesses should not pay cash
dividends that exceed its net income or that could only be funded in ways that
weaken the bank holding company's financial health, such as by borrowing.
Furthermore, the OCC also has authority to prohibit the payment of dividends by
a national bank when it determines such payment to be an unsafe and unsound
banking practice.

  Regulation of Lake State

         Lake State is chartered by the State of Florida.  It is subject to
comprehensive regulation, examination and supervision by the Florida Department
and the FDIC, and is subject to other laws and regulations applicable to banks.
Such regulations include limitations on loans to a single borrower and to its
directors, officers and employees; restrictions on the opening and closing of
branch offices; the maintenance of required capital and liquidity ratios; the
granting of credit under equal and fair conditions; disclosure of the cost and
terms of such credit; and restrictions as to permissible investments.  Lake
State is examined periodically by both the Florida Department and the FDIC, to
each of whom it submits regular periodic reports regarding its financial
condition and other matters.  Both the Florida Department and the FDIC have a
broad range of powers to enforce regulations under their respective
jurisdictions, and to take discretionary actions determined to be for the
protection of the safety and soundness of Lake State, including the institution
of cease and desist orders and the removal of directors and officers.  Lake
State's deposit accounts are insured by the Bank Insurance Fund of the FDIC up
to a maximum of $100,000 per insured depositor.  The FDIC issues regulations,
has authority to conduct periodic examinations, requires the filing of reports
and generally supervises the operations of its insured banks.  This supervision
and regulation is intended primarily for the protection of depositors.

         Any insured bank which is not operated in accordance with or does not
conform to FDIC regulations, policies and directives may be sanctioned for
non-compliance.  Proceedings may be instituted against any insured bank or any
director, officer, or employee of such bank engaging in unsafe and unsound
practices, including the violation of applicable laws and regulations.  The
FDIC has the authority to terminate insurance of accounts pursuant to
procedures established for that purpose.

  Capital Guidelines

         The Federal Reserve Board has issued risk-based capital guidelines for
bank holding companies.  Under the guidelines, the minimum ratio of capital to
risk-weighted assets (including certain off-balance sheet items, such as
standby letters of credit) is 8%.  To be considered a "well capitalized" bank
or bank holding company under the guidelines, a bank or bank holding company
must have a total risk-based capital ratio in excess of 10%.  At December 31,
1995, SouthTrust and all of SouthTrust's subsidiary banks were sufficiently
capitalized to be considered "well capitalized."  See "SUPERVISION AND
REGULATION - The Federal Deposit Insurance Corporation Improvement Act."  At
least half of the total capital is to be comprised of common equity, retained
earnings and a limited amount of perpetual preferred stock, after subtracting
goodwill and certain other adjustments ("Tier 1 capital").  The remainder may
consist of perpetual debt, mandatory convertible debt securities, a limited
amount of subordinated debt, other preferred stock not qualifying for Tier 1
capital and a limited amount of loan loss reserves ("Tier 2 capital").
SouthTrust's national banking subsidiaries are subject to similar capital
requirements adopted by the OCC, and its state non-member bank subsidiaries are
subject to similar capital requirements adopted by the FDIC.  In addition, the
Federal Reserve Board, the OCC and the FDIC have adopted a minimum leverage
ratio (Tier 1 capital to total assets) of 3%.  Generally, banking organizations
are expected to operate well above the minimum required capital level of 3%
unless they meet certain specified criteria, including that they have the
highest regulatory ratings.  Most banking organizations are required to
maintain a leverage ratio of 3% plus an additional cushion of at least 1% to
2%.  The guidelines also provide that banking organizations experiencing
internal growth or making acquisitions will be expected to maintain strong
capital positions substantially above the minimum supervisory levels without
significant reliance upon intangible assets.





                                       35
<PAGE>   38


         Lake State, as a state non-member bank, is subject to the capital
adequacy guidelines specified by the FDIC.  In order to avoid being considered
undercapitalized, the FDIC requires Lake State to maintain a minimum Tier 1
capital of 4%, Tier 1 leverage ratio of at least 4% and total risk-based
capital of at least 8% of risk weighted assets.  At December 31, 1995, Lake
State was sufficiently capitalized to be considered "well capitalized."

         A depository institution may be deemed to be in a capitalization
category that is lower than is indicated by its actual capital position if it
receives an unsatisfactory examination rating.

         The following table sets forth the various regulatory capital ratios
of each of SouthTrust and Lake State as of the periods indicated:

</TABLE>
*  Under the risk-based and leverage capital guidelines, regulatory required
   minimums are 4% and 8% for Tier 1 and Total Capital ratios, respectively.
   The leverage ratio must be maintained at a level generally considered to be
   in excess of 3%.

         Under the Financial Institutions Reform, Recovery and Enforcement Act
of 1989 ("FIRREA"), failure to meet the capital guidelines could subject a
banking institution to a variety of enforcement remedies available to federal
regulatory authorities, including the termination of deposit insurance by the
FDIC.


  The Federal Deposit Insurance Corporation Improvement Act

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") substantially revised the depository institution regulatory and
funding provisions of the Federal Deposit Insurance Act and made revisions to
several other federal banking statutes.  Among other things, FDICIA requires
the federal banking regulators to take prompt corrective action in respect of
depository institutions that do not meet minimum capital requirements.  FDICIA
establishes five capital tiers:  "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" and "critically
undercapitalized."  A depository institution is well capitalized if it
significantly exceeds the minimum level required by regulation for each
relevant capital measure, adequately capitalized if it meets each such measure,
undercapitalized if it fails to meet any such measure, significantly
undercapitalized if it is significantly below such measure and critically
undercapitalized if it fails to meet any critical capital level set forth in
regulations.  The critically undercapitalized level occurs where tangible
equity is less than 2% of total tangible assets or less than 65% of the minimum
leverage ratio to be prescribed by regulation (except to the extent that 2%
would be higher than such 65% level).  A depository institution may be deemed
to be in a capitalization category that is lower than is indicated by its
actual capital position if it receives an unsatisfactory examination rating.

         FDICIA generally prohibits a depository institution from making any
capital distribution (including payment of a dividend) or paying any management
fee to its holding company if the depository institution would thereafter be
undercapitalized.  Undercapitalized as of depository institutions also became
subject to restrictions on borrowing from the Federal Reserve System, effective
as of December 19, 1993.  In addition, undercapitalized depository institutions
are subject to growth limitations and are required to submit capital
restoration plans.  A depository





                                       36
<PAGE>   39


institution's holding company must guarantee the capital plan, up to an amount
equal to the lesser of 5% of the depository institution's assets at the time it
becomes undercapitalized or the amount of the capital deficiency when the
institution fails to comply with the plan.  The federal banking agencies may
not accept a capital plan without determining, among other things, that the
plan is based on realistic assumptions and is likely to succeed in restoring
the depository institution's capital.  If a depository institution fails to
submit an acceptable plan, it is treated as if it is significantly
undercapitalized.

         Significantly undercapitalized depository institutions may be subject
to a number of requirements and restrictions, including orders to sell
sufficient voting stock to become adequately capitalized, requirements to
reduce total assets and cessation of receipt of deposits from correspondent
banks.  Critically undercapitalized depository institutions are subject to
appointment of a receiver or conservator.

         FDICIA provides authority for special assessments against insured
deposits and for the development of a general risk-based deposit insurance
assessment system.  The risk-based insurance assessment system would be used to
calculate a depository institution's semiannual deposit insurance assessment
based on the probability (as defined in the statute) that the deposit insurance
fund will incur a loss with respect to the institution.

         Effective with fiscal years beginning after December 31, 1992, each
insured institution having over $500 million in total assets is required to
submit to the FDIC and make available to the public an annual report on the
institution's financial condition and management's responsibility and
assessment of the internal controls over financial reporting.  The
institution's independent public accountant will be required to audit and
attest to certain of the statements made in that annual report.

         FDICIA amended prior law with respect to the acceptance of brokered
deposits by insured depository institutions to permit only a "well capitalized"
(as defined in the statute as significantly exceeding each relevant minimum
capital level) depository institution to accept brokered deposits without prior
regulatory approval.  A depository institution which has a capital level
category of "undercapitalized" may not accept brokered deposits without prior
regulatory approval.  FDICIA also established new uniform disclosure
requirements for the interest rates and terms of deposits accounts.

         FDICIA also contains various provisions related to an institution's
interest rate risk.  Under certain circumstances, an institution may be
required to provide additional capital or maintain higher capital levels to
address interest rate risks.

         The foregoing necessarily is a general description of certain
provisions of FDICIA and does not purport to be complete.  Several of the
provisions of FDICIA are being implemented through the adoption of regulations
by various federal banking agencies.  FDICIA is not expected to have a material
effect on the results of operations of SouthTrust or Lake State.

  The Riegle-Neal Interstate Banking and Branching Efficiency Act

         In September 1994, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Interstate Banking Act") became law.  The
Interstate Banking Act has two major provisions regarding the merger,
acquisition and operation of  banks across state lines.  First it provides that
effective September 29, 1995, adequately capitalized and managed bank holding
companies are permitted to acquire banks in any state.  State laws prohibiting
interstate banking or discriminating against out-of-state banks will be
preempted as of the effective date.  States cannot enact laws opting out of
this provision; however, states may adopt a minimum age restriction requiring
that target banks located within the state be in existence for a period of
years, up to a maximum of five years, before such bank may be subject to the
Interstate Banking Act.  The Interstate Banking Act establishes deposit caps
which prohibit acquisitions that would result in the acquiror controlling 30%
or more of the deposits of insured banks and thrifts held in the state in which
the acquisition or merger is occurring or in any state in which the target
maintains a branch or 10% or more of the deposits nationwide.  State-level
deposit caps are not preempted as long as they do not discriminate against
out-of- state acquirers, and the federal deposit caps apply only to initial
entry acquisitions.

         In addition to the foregoing, the Interstate Banking Act provides that
as of June 1, 1997, adequately capitalized and managed banks will be able to
engage in interstate branching by merging banks in different states.  However,
unlike the interstate banking provision, states may opt out of the application
of this provision by enacting





                                       37

specific legislation before June 1, 1997.  If a state does opt-out, banks will
be required to comply with the such state's provisions with respect to
branching across state lines.


                       CERTAIN INFORMATION CONCERNING THE
                             BUSINESS OF LAKE STATE

GENERAL

         Lake State was organized in 1988 as a banking corporation under the
laws of the State of Florida and began operation in July 1988 with the primary
purpose of serving the banking needs of the residents of Pasco County, Florida
and surrounding areas.  Since its organization, Lake State has provided most
traditional commercial banking services including interest and non-interest
bearing checking and savings accounts, commercial, mortgage and installment
loans and certificates of deposit.

MARKET AREA

         Lake State's sole office is located at 21780 State Road 54, Lutz,
Florida 33549.  Though Lake State's address has been designated as Lutz,
Florida by the United States Postal Service, the physical location of the sole
office is in the unincorporated community of Land O'Lakes, Florida.  Land
O'Lakes, Florida is located in Pasco County on the west coast of the State of
Florida and has a population of approximately 14,000 people.  Lake State's
office is approximately 14 miles north of Tampa, Florida.  At April 1994, Pasco
County, Florida and Hillsborough County, Florida had residential populations of
approximately 299,000 and 865,000 people, respectively.  While Lake State's
overall market area extends throughout Pasco County and Hillsborough County, at
the present time it draws most of its business from within central Pasco County
and northwestern Hillsborough County, (the "Primary Service Area") and
estimates that more than 75% of its business comes from customers whose
business or residences are located in Lake State's Primary Service Area.  Lake
State's Primary Service Area is the region bounded on the east by U.S.
Interstate Highway 75, on the north by State Road 52, on the west by a number
of different roads approximating the alignment of Gunn Highway, and on the
south by a number of different roads approximating the alignment of Sunset
Lane.  The service area was determined by evaluating a number of factors
including but not limited to, natural and man-made barriers, competition in the
area, transportation networks and the distance persons will customarily travel
to conduct their banking business.  Another consideration in determining the
service area was the fact that Land O'Lakes has been a focal point for business
activity and residential growth in Central Pasco County.  Lake State intends,
for the near future, to service (with only a few exceptions) only residents and
businesses located in Pasco and Hillsborough Counties, but may choose to accept
some business from outside these areas.

DEPOSIT ACTIVITIES

         Lake State's deposit services include interest bearing and
non-interest bearing business and individual checking accounts, savings
accounts, NOW accounts, certificates of deposit, money market accounts and IRA
accounts.  It is the policy of Lake State to monitor its competition in order
to keep the rates paid on its deposits at a competitive level.  For additional
information regarding Lake State's deposit accounts, see "LAKE STATE
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS - Deposits."

LOAN ACTIVITIES

         Lake State invests certain of the deposits made with it and its equity
capital in commercial loans, mortgage loans and a full line of
consumer-oriented loans.  Lake State's loans are concentrated in three major
areas: commercial loans, construction and real estate loans, and installment
loans.  As of December 31, 1995, approximately 75% of the loan portfolio
consisted of loans collateralized by first or second mortgages on residential
or commercial real estate located in Pasco and Hillsborough Counties and the
surrounding areas.

         Lake State's commercial loans include loans to individuals and
small-to-medium-sized businesses located primarily in Pasco and Hillsborough
Counties for working capital, equipment purchases, and various other business
purposes.  Commercial loans may be made at variable or fixed rates of interest.
It is Lake State's policy to make





                                       38
<PAGE>   41


commercial loans to qualified businesses collateralized by inventory, account
receivables, equipment, real property and lines of credit.

         Lake State's real estate loans are collateralized by mortgages and
consist primarily of loans to individuals and businesses for the purchase,
improvement of or investment in real estate and for various other consumer and
business purposes (whether or not related to the real estate securing them).
Lake State also engages in lending to individuals and builders for the
construction of single-family residences.  These real estate loans may be made
at fixed or variable interest rates.  It is Lake State's policy to require a
minimum of 20% down payment on commercial real estate loans.

         Lake State's installment loan portfolio consists primarily of loans to
individuals for various consumer purposes, but includes some business purpose
loans which are payable on an installment basis.

         For additional information regarding Lake State's loans portfolio, see
"LAKE STATE MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS - Loan Portfolio" and "- Risk Elements of Loan
Portfolio."

OTHER SERVICES

         Lake State provides most other traditional commercial and consumer
banking services, money orders, traveler's cheques, notary service, safe
deposit services and wire transfers.  Lake State owns an automatic teller
machine (ATM) and offers debit cards to its customers which can be used at ATMs
which allow access to the HONOR network.

COMPETITION

         The banking industry in general, and Lake State's Primary Service Area
in particular, is characterized by significant competition for both deposits
and lending opportunities.  In its market area, Lake State competes with other
commercial banks, savings and loan associations, credit unions, finance
companies, mutual funds, insurance companies, brokerage and investment banking
firms and various other non-bank competitors.  Competition for deposits may
have the effect of increasing the rates of interest Lake State will pay on
deposits, which would increase Lake State's cost of money and possibly reduce
its net income.  Competition for loans may have the effect of lowering the rate
of interest Lake State will receive on its loans, which would lower Lake
State's return on invested assets and possibly reduce its net income.  Many of
Lake State's competitors have been in existence for a significantly longer
period of time than Lake State and may offer certain services, such as trust
services, that Lake State does not provide at this time.  The profitability of
Lake State depends upon its ability to compete in its market area.

         In recent years important federal and state legislation has heightened
the competitive environment in which financial institutions must conduct their
business, and the potential for competition among financial institutions of all
types has increased significantly.  See "SUPERVISION AND REGULATION - The
Riegle-Neal Interstate Banking and Branching Efficiency Act."  There are
approximately 181 established or future offices of commercial banks and savings
and loan associations located in Hillsborough County and 94 established or
future offices of commercial banks and savings and loan associations located in
Pasco County.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


OVERVIEW


         Lake State commenced operations on July 15, 1988, with $2,999,130 in
capital after deducting $115,061 of pre- opening expenses from the proceeds of
its initial stock offering.  Lake State's activities since inception have
primarily consisted of accepting deposits and originating a variety of loans.
Lake State, as a local independent bank, follows a philosophy of developing its
equity and deposit base and focusing its lending activities within its market
area.  Lake State's total assets increased from 1988 through 1995, though its
capital ratios declined from 1988 through 1990 due to the operating losses
which were incurred.  See "Liquidity and Capital Resources."  In January of
1991 Lake State's senior management was replaced.  Since that time, Lake
State's total assets, total deposits and total loans (net) have grown as
follows:

         The following discussion and analysis is based upon Lake State's
results of operations and financial condition for the years ended December 31,
1995, 1994, 1993, and 1992 and for the three months period ended March 31,
1996, and should be read in conjunction with the Financial Statements of Lake
State and the related Notes appearing elsewhere in this Proxy
Statement/Prospectus.  Unless otherwise noted, all average information has been
derived from quarterly Call Reports filed by Lake State with the FDIC.
    

RESULTS OF OPERATIONS

         Lake State's net income for the year ended December 31, 1995 was
$511,641 versus net income of $446,118 for the year ended December 31, 1994.
Lake State had a net income of $379,638 for the year ended





                                       40
<PAGE>   43


December 31, 1993.  On a per share basis, net income for the years ended
December 31, 1995, 1994 and 1993 was $1.62, $1.41, and $1.20 per share,
respectively.

         The increase in net income from $379,638 in 1993 to approximately
$446,000 in 1994 generally resulted from decreases in non-earning assets and
litigation losses.

         The increase in net income from $446,118 in 1994 to approximately
$512,000 in 1995 generally resulted from decreased costs from the operation of
other real estate ($11,028 in 1995 versus $89,614 in 1994), decreased loan
provisions ($11,000 in 1995 versus $30,000 in 1994), and an increase in the
interest rate spread from 5.13% in 1994 to 5.19% in 1995.
                            
        Net Interest Income.  The major component of Lake State's earning
capacity is net interest income, which represents the difference or spread
between interest income on interest-earning assets, primarily loans, investment
securities and Federal funds sold, and interest expense on interest-bearing
liabilities, primarily deposits and borrowed funds.  Net interest income
depends primarily on the volume of average interest-earning assets and average
interest-bearing liabilities and Lake State's interest rate spread, which is
the difference between the average yield earned on its loan and investment
portfolios and the average rate paid on its deposits and borrowings.  Lake
State's interest rate spread is impacted by interest rates, deposit flows and
loan demands.

         Lake State's net interest income was approximately $1,596,000 for the
year ended December 31, 1995, approximately $1,294,000 for the year ended
December 31, 1994, and approximately $1,104,000 for the year ended December 31,
1993, representing an increase of 23% from 1994 to 1995 and an increase of 17%
from 1993 to 1994.  Lake State's interest rate spread was 5.19% for the year
ended December 31, 1995, 5.13% for the year ended December 31, 1994 and 4.83%
for the year ended December 31, 1993.  The increase in the interest rate spread
for the year ended December 31, 1995 when compared to the year ended December
31, 1994 was due to the fact that the yields on average interest-earning assets
increased at a faster rate than the increase in the rates paid by Lake State on
its deposits and borrowings due to prevailing market conditions during the
period.  Net interest income also increased during the comparable period due to
an increase in Lake State's total average interest-earning assets.

         The increase in Lake State's interest rate spread from 4.90% in 1993
to 5.13% in 1994 is due to the fact that the yields on average interest-earning
assets increased, while the rates paid by Lake State on its deposits and
borrowings decreased as a result of prevailing market conditions during the
period.  In addition, Lake State experienced an increase in its
interest-earning assets.

   
         Interim data for the three months ended March 31, 1996 and 1995 shows
that net income increased from $90,263 through March 31, 1995 to $92,377
through March 31, 1996.  This increase in net income was a result of an
increased level of average interest-earning assets which increased from
$22,563,000 at March 31, 1995 to $26,521,000 at March 31, 1996.
    

   
         The following table shows for each category of interest-earning
liabilities, the average balance outstanding, the amount of interest earned or
paid on such amounts and the average yield earned or rate paid thereon for the
three years ended December 31, 1995, 1994 and 1993 and for the three months
ended March 31, 1996 and 1995.  The table also shows the net yield on
interest-earning assets for each of those periods.

         The following table represents the effect on net interest income of
changes from prior comparable periods in volume, rate and rate/volume for the
categories of interest-earning assets and interest-bearing liabilities set
forth below and for the periods indicated.  The effect of a change in volume
has been determined by applying the rate in the earlier period to the change in
volume during the current period.  The effect of a change in rate was
determined by applying the change in the rate from the earlier period to the
volume from the earlier period.  The rate/volume variance has been allocated to
the volume variance.  Average quarterly balances of all categories in each
reported period were used in the volume computations.  Average quarterly rates
in each period were used in rate computations.

         Asset/Liability.  Lake State seeks to maintain a program of asset and
liability management designed to limit its vulnerability to interest rate risk.
The principal measure of Lake State's exposure to interest rate risk is its
interest rate sensitivity "gap", which is the difference between interest rate
sensitive assets and interest rate sensitive liabilities.  An asset or
liability is considered to be interest rate sensitive if it will reprice or
mature within the period analyzed, usually one fiscal year.  A gap is
considered positive when the amount of interest rate sensitive assets exceeds
the amount of interest rate sensitive liabilities.  When the opposite occurs,
the gap is considered to be negative.  During periods of rising interest rates,
a negative gap would tend to adversely affect net interest income, while a
positive gap would tend to result in an increase in net interest income.
During periods of declining interest rates, the inverse would tend to occur.
If the maturities of Lake State's assets and liabilities were equally flexible
and moved concurrently, the impact of any material or prolonged increase (or
decrease) in interest rates on net interest income would be minimal.

         Lake State's asset and liability policies are directed toward
matching, to the extent possible, its interest rate sensitive assets and
interest rate sensitive liabilities to achieve and maintain a satisfactory
differential between its interest income and interest expense regardless of the
general level and movement of interest rates.  To this end, Lake State's
management reviews on a periodic basis the duration of asset and liability
categories.  The following tables summarize the interest rate sensitive assets
and liabilities of Lake State at December 31, 1995, based on the period during
which they mature or are subject to repricing.

         The increase in average interest-earning assets from December 31, 1993
to 1994 was predominantly the result of a substantial increase in the loan
portfolio from $13,605,000 to $15,136,000.  The increase in average
interest-earning assets from December 31, 1994 to 1995 was the result of an
increase in the loan portfolio from $15,136,000 to $17,141,000 and an increase
in the securities portfolio from $5,238,000 to $6,686,000.

   
         Average interest-earning assets increased from the three months ended
March 31, 1995 to the three months ended March 31, 1996 due to increase in loan
portfolio of 17.54% and increase in investment securities of 20.76%.

         Non-interest Earning Assets.  Average non-interest earning assets
accounted for 7.18% of average total assets at December 31, 1995 compared with
9.74% of average total assets at December 31, 1994 and 12.52% of total average
assets at December 31, 1993.  Average non-interest earning assets accounted for
8.21% of average total assets at March 31, 1995 compared with 6.60% of total
assets at March 31, 1996.  Non-interest earning assets at December 31, 1995
primarily consisted of cash and funds placed in accounts with other banks,
property and equipment, accrued interest receivable and other real estate
owned.
    

   
         Funding Sources.  The primary source of funds for Lake State's lending
and investing activities is deposits.  The following table summarizes Lake
State's average deposits at December 31, 1995, 1994 and 1993 and at March 31,
1996, 1996 and 1995:

         As of December 31, 1995, deposits of Lake State were distributed among
demand deposits (21.81%), Money Market (15.94%), savings and time deposits
(49.43%), and NOW accounts (12.82%).  Lake State's deposits are attracted
primarily from individuals and professionals and also from small and medium
size businesses and agricultural enterprises located predominantly in Lake
State's Primary Service Area.  As of March 31, 1996, approximately 30% of Lake
State's total deposits were from businesses and approximately 70% were from
individuals.  Management of Lake State does not believe that the loss of any
one or a few of its deposit accounts would have a materially adverse effect
upon the operations of Lake State or erode its deposit base.
    

         The increase in Lake State's interest-earning assets from year end
1993 to year end 1995 was funded principally through increased deposits during
those periods.  Although this increase in deposits provided the necessary funds
to support Lake State's aggressive lending and investing activities during that
period, the stable to declining yields paid by Lake State on its deposits
during that same period contributed to an increase in the net interest margin
on Lake State's interest-earning assets during this period.

   
         Other Operating Income.  Lake State's other operating income was
$218,920 for the year ended December 31, 1995 as compared to $212,274 for the
year ended December 31, 1994 and $194,033 for the year ended December 31, 1993.
Lake State's other operating income was $57,043 for the three months ended
March 31, 1996 as compared to $46,645 for the three months ended March 31,
1995.  Lake State's other operating income is comprised primarily of gains on
sales of securities, service charges on deposit accounts, NSF charges and safe
deposit box rental fees.  The growth in other operating income from 1994 to
1995 was due primarily to gains on sales of securities, with growth in other
operating income for 1993 to 1994 due primarily to increased service charges on
deposit activity.
    

   
         Other Operating Expenses.  The following table sets forth Lake State's
other operating expenses for the years ended December 31, 1995, 1994 and 1993
and for the three months ended March 31, 1996 and 1995:

         Lake State's other operating expenses increased from 1993 to 1995 by
10.65%.  The principal reasons for the change in other operating expenses from
1993 to 1995 were increases in employee compensation, data processing costs and
director fees, offset by lower occupancy costs.

   
         Employee compensation and benefits increased 6.01% from the year ended
December 31, 1993 to the year ended December 31, 1994, and increased 7.37% from
the year ended 1994 to the year ended December 31, 1995.  For the three months
ended March 31, 1996 compared to the three months ended March 31, 1995 employee
compensation increased 35.62%.  These fluctuations were primarily due to
changes in the number of employees and annual merit increases in salaries and
performance based bonuses.
    

         Allowance for Loan Losses.  The allowance for the loan losses is
established through a provision for loan losses charged to expense.  Loans are
charged against the allowance for loan losses when management of Lake State
believes that the collectibility of the principal on such loans is unlikely.
The allowance is an amount that management of Lake State believes will be
adequate to absorb losses inherent in existing loans and commitments to extend
credit, based on evaluations of the collectibility of loans, which takes into
consideration any prior loan loss experience on loans and commitments to extend
credit.  The evaluations also take into consideration such factors as changes
in the nature and volume of the loan portfolio, overall portfolio quality, loan
concentrations, commitments, and current and anticipated economic conditions
that may affect the borrowers' ability to pay.  Historical results indicate
that the greatest risk in Lake State's loan portfolio has arisen in the real
estate category.  See "-Risk Elements of Loan Portfolio" for a description of
non-accrual loans and loans past due 90 days or more in Lake State's loan
portfolio.

         At December 31, 1995 and March 31, 1996 Lake State's loan loss reserve
was 1.46% of loans. The peer group's loan loss reserve was approximately 1.45%
of loans as of December 31, 1995.  Any future increase in the loan loss reserve
would be charged to current operations and thus reduce income or increase the
operating loss, as the case may be.

         Lake State conducts a quarterly review of the allowance for loan
losses and seeks to maintain a balance which is adequate but not excessive
based on all the available evidence.

INCOME TAXES

         The Bank accounts for income taxes in accordance with Statement of
Financial Accounting Standard No. 109 (SFAS 109), Accounting for Income Taxes.
Under SFAS 109, the asset and liability method is used in accounting for income
taxes.  Under this method, deferred tax assets and liabilities are determined
based on differences between financial reporting and tax bases of assets and
liabilities and are measured using the enacted marginal tax rates.  The effect
on deferred income taxes of a change in tax rates is recognized in income in
the period that includes the enactment date.

         Significant components of the provision for income taxes for the year
ending December 31, 1995 and 1994 is as follows:

LIQUIDITY AND CAPITAL RESOURCES

         The average life of Lake State's investment portfolio at December 31,
1995 is approximately three years.  See "-Investment Securities."  It is the
objective of Lake State to maintain a loan to deposit ratio of approximately
75%.  Lake State has not experienced liquidity problems in the past due to
growth in Lake State's deposit base. As a result, Lake State maintained a
liquidity level in excess of 25% for most of 1994 and 1995.  In the future,
current, seasonal and unanticipated liquidity requirements will be met by
managing the maturity structure of high quality marketable assets and by
maintaining discretionary access to short term funding sources.  Lake State
currently maintains Federal Funds borrowing lines and a reserve repurchase
agreement with various correspondents which aggregate $1,500,000 and $500,000
respectively.

         In the normal course of business, the capital position of Lake State
is reviewed by management of Lake State to ensure that Lake State's capital is
adequate and consistent with expected growth.  The capital position of Lake
State represents the level of capital needed to support Lake State's expansion.
Since Lake State's inception, the primary capital to support Lake State's asset
base has come entirely from the original capitalization of Lake State and
internally generated profits.

         The FDIC has specified guidelines for purposes of evaluating a bank's
capital adequacy.  Those guidelines assign weighted levels of risk to asset
categories to measure capital adequacy.  Specifically, in order to avoid being
considered undercapitalized, the FDIC requires Lake State to maintain a minimum
Tier 1 Capital of at least 4%, Tier 1 Leverage ratio of at least 4% and a total
risk-based capital of at least 8% of risk weighted assets.  As of December 31,
1995 and March 31, 1996 Lake State met the requirements to be categorized as a
well capitalized institution under the applicable FDIC regulations.  See
"SUPERVISION AND REGULATION-Capital Guidelines."

   
         At December 31, 1995 and March 31, 1996 Lake State had no significant
commitments for capital expenditures.  In the normal course of business, Lake
State has various outstanding commitments to extend credit that are not
reflected in the accompanying financial statements.  At December 31, 1995 and
1994, commitments to extend credit and standby letters of credit aggregated
approximately $1,943,000 and $1,914,000, respectively.  Lake State's exposure
to credit loss in the event of non-performance by the other party to the
financial instrument for loan commitments and standby letters of credit is
represented by the contractual amounts of those instruments.  Lake State uses
the same credit policies in making commitments and conditional obligations as
it does for on-balance-sheet instruments.
    

         Since certain of the loan commitments may expire without being drawn
upon, the total commitment amount does not necessarily represent future cash
requirements.  Lake State evaluates each borrower's credit worthiness on a
case-by-case basis.  The amount of collateral obtained, if deemed necessary by
Lake State upon extension of credit, is based on management's credit evaluation
of the counterparty.  Collateral held varies, but may include real estate,
automobiles, boats, inventory, receivables and deposit accounts.

         Standby letters of credit are conditional commitments issued by Lake
State to guarantee the performance of a customer to a third party.  The credit
risk involved in issuing letters of credit is essentially the same as that
involved in extending loan facilities to customers.  There are no significant
concentrations of credit risk with any individual counterparty to originate
loans.

IMPACT OF INFLATION

         The financial statements and related data presented herein have been
prepared using the measurement of financial position and operating results in
terms of historical dollars without considering changes in the relative
purchasing power of money over time due to inflation.  The impact of inflation
on banks differs from its impact on nonfinancial institutions.  Banks, as
financial intermediaries, have assets which are primarily monetary in nature
and which tend to fluctuate in concert with inflation.  This is especially true
for banks with a high percentage of rate-sensitive interest-earning assets and
interest-bearing liabilities.  A bank can reduce the impact of inflation if it
can manage its interest rate sensitivity gap.  This gap represents the
difference between variable rate assets and variable rate liabilities.  Lake
State attempted to structure its assets and liabilities and manage its interest
rate sensitivity gap accordingly, thus seeking to minimize the potential
effects of inflation.  For information on Lake State's management of its
interest rate sensitive assets and liabilities, see "Liquidity and Capital
Resources" and "Asset/Liability Management."

daily basis and has been derived from quarterly Call Reports filed by Lake
State with the FDIC.

INVESTMENT SECURITIES

         Lake State's investment securities which are available for sale are
recorded at fair value.  Unrealized gains and losses on securities available
for sale, net of deferred taxes, are shown as a separate component of
stockholders' equity on the balance sheets.  At December 31, 1995, an
unrealized holding gain of $2,506, net of deferred taxes of $1,002, was shown
as a component of stockholders' equity.  At December 31, 1994, an unrealized
holding loss of $81,216, net of deferred taxes of $32,486, was shown as a
component of stockholders' equity.

RISK ELEMENTS OF LOAN PORTFOLIO

         Loans on which the accrual of interest has been discontinued are
designated as non-accrual loans.  Accrual of interest on loans is discontinued
when reasonable doubt exists as to the full, timely collection of interest or
principal.  When a loan is placed on non-accrual status, all interest
previously accrued but not collected is reversed against current period
interest income.  Income on such loans is then recognized only to the extent
that cash is received and where the future collection of principal is probable.
Interest accruals are resumed on such loans only when they are brought fully
current with respect to interest and principal and when, in the judgement of
management, the loans are estimated to be fully collectible as to both
principal and interest.  This policy applies to all types of loans.  Past due
loans reflect the total principal balance of any loans which are not being paid
as to principal or interest according to the terms of the contract.  Other real
estate owned represents properties acquired through foreclosure.

         The following table reports, for the periods indicated, loans

         Loans on which accrual of interest has been discontinued amounted to
approximately $87,700 and $91,000 at December 31, 1995 and 1994, respectively.
If interest on those loans had been accrued, such income would have
approximated $2,000 and $11,4000 for 1995 and 1994, respectively.

         As of December 31, 1995, Lake State had only one loan, for $87,700, in
non-accrual status.  This represented a real estate mortgage on certain real
property located in Land O'Lakes, Florida.  Other real estate owned at December
31, 1995 consists of two properties.  Both properties are vacant lots zoned
residential in Wesley Chapel, Florida.  These properties are currently listed
with a real estate agent.

         Generally, loans for construction and commercial real estate can
present a higher degree of risk to a lender depending upon, among other things,
whether the borrower has a permanent financing at the end of a loan period,
whether the project is income producing, and changing economic conditions.
Commercial and financial loans also entail certain additional risks since they
usually involve large loan balances to a single borrower or a related group of
borrowers, resulting in a more concentrated loan portfolio, and since their
repayment is usually dependent upon the successful operation of the commercial
enterprise and is also subject to adverse conditions in the economy.  While
there is no assurance that Lake State will not realize any losses on its
construction loans or commercial real estate loans, management is of the belief
that the degree of risk related to such loans is not significant to Lake State.


DEPOSITS

         Lake State offers a variety of deposit products ranging in maturity
from demand-type accounts to certificates of deposit with varying maturities.
Lake State's deposits are primarily derived from the Pasco and Hillsborough
Counties.  Lake State does not have a concentration of deposits from any one
source, the loss of which would have a materially adverse effect on the
business of Lake State.  The following table sets forth the average amounts of
deposits and the average rates paid by Lake State on such deposits for the
periods indicated.

COMPARISON OF THREE MONTHS ENDED MARCH 31, 1996 AND 1995


   
         Overview.  The Bank recorded net income of $92,377 for the three
months ended March 31, 1996, or earnings per share of $0.29.  Return on average
assets was 1.28% for the first three months of 1996, while the return on
shareholders' equity was 10.12%, on an annualized basis.  For the three months
ended March 31, 1995, the Bank recorded net income of $90,263, or earnings per
share of $0.29.  Return on average assets was 1.43% for the first three months
of 1995, while the return on shareholders' equity was 11.19%.
    

   
         Net Interest Income.   The growth in loans resulted in a steady 
increase in net interest income during the first three months of 1996.  Net
interest income for the three month period ended March 31, 1996 and 1995 was
$404,086 and $357,469, respectively, on a $26,521,000 and $22,563,000,
respectively, average balance of interest-earning assets.  Interest income from
loans during the same period comprised 82.1% and 83.0%, respectively, of the
total interest income and earned an average yield of 10.74% and 10.66%,
respectively, while interest income from investments and federal funds sold
earned an average yield of 5.32% and 5.24%, respectively, on an annualized
basis.  Total interest expense for the three month period in 1996 was $197,058
on average outstanding balances of interest-bearing liabilities $19,237,000,
compared to expense of $153,081 on average outstanding balances of
interest-bearing liabilities of $16,309,000 for the same period in 1995.  The
average cost of interest-bearing liabilities for the first three months of 1996
and 1995 was 4.10% and 3.75%, respectively, on an annualized basis.
    

   
         Provision for Loan Losses.  Through the three month period ended March
31, 1996, $7,000 was recorded to the loan loss provision, compared to the
$6,000 recorded to the provision during the first three months of 1995.
    

   
         Non-interest Income.  For the three month periods ended March 31, 1996
and 1995, non-interest income totaled $57,043 and $44,494, respectively, an
increase of approximately 28.2%.  This increase was primarily attributable to
increased service charges and fees from customer deposits.
    

   
         Non-Interest Expense.  Non-interest expense for the three months ended
March 31, 1996 and 1995, totaled $310,872 and $252,500, respectively, an
increase of $58,372, or 23.1%.  This increase was primarily the result of an
increase in salaries and employee benefits of $38,348 or 33.6%, which resulted
from changes in the number of employees and annual merit increases in salaries
and performance based bonuses.

REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of Lake State Bank:

We have audited the accompanying balance sheets of Lake State Bank as of
December 31, 1995 and 1994, and the related statements of income, shareholders'
equity and cash flows for the years then ended.  These financial statements are
the responsibility of the Bank's management.  Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Lake State Bank as of December
31, 1995 and 1994, and the results of its operations and its cash flows for the
years then ended, in conformity with generally accepted accounting principles.

As discussed in Note 1 to the financial statements, effective January 1, 1994,
the Bank changed its method of accounting for investments.

LAKE STATE BANK
NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

   The accounting and reporting policies of Lake State Bank (the Bank)
   conform to generally accepted accounting principles and to general practice
   within the banking industry.  The following summarizes the more significant
   of these policies.

   INVESTMENT SECURITIES - Management determines the appropriate
   classification of its securities at the time of purchase.

   At January 1, 1994, the Bank adopted Statement of Financial Accounting
   Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and
   Equity Securities."  SFAS No. 115 requires the reporting of certain
   securities at fair value except for those securities which the Bank has the
   positive intent and ability to hold to maturity.

   SECURITIES HELD TO MATURITY - Investment securities which are acquired
   with the intent and ability to hold to maturity are reported at amortized
   cost.  Sales of securities classified as held to maturity are prohibited
   except under rare circumstances.  These securities are adjusted for
   amortization of premiums and accretion of discounts, which are recognized as
   adjustments in interest income. If a security has a decline in fair value
   below its amortized cost that is other than temporary, then the security
   will be written down to its new cost basis by recording a loss in the
   statement of operations.

   SECURITIES AVAILABLE FOR SALE - Investment securities which are
   classified as available-for-sale are reported at fair value with unrealized
   gains and losses, net of the applicable deferred tax effect, excluded from
   earnings and reported in a separate component of stockholders' equity.  Upon
   disposition, unrealized gains or losses previously reported as a component
   of shareholders' equity are recognized and included in current earnings.  If
   a security has a decline in fair value below its amortized cost that is
   other than temporary, then the security will be written down to its new cost
   basis by recording a loss in the statement of operations.

   TRADING SECURITIES - Investment securities which are purchased and
   classified with the intent of being held for trading purposes are reported
   at fair value, with unrealized gains and losses included in earnings.  The
   Bank does not have any securities classified as trading.

   Gains and losses on disposition are recognized using the specific
   identification method.

   LOANS AND ALLOWANCE FOR LOAN LOSSES - Loans are stated at the amount of
   unpaid principal, reduced by deferred loan fees and an allowance for loan
   losses. Interest income is recognized using the simple interest method on
   daily balances of principal amounts outstanding.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

   The allowance for loan losses is established through a provision for
   loan losses charged to expenses.  Loans are charged against the allowance
   for loan losses when management believes that the collectibility of the
   principal is unlikely.  The allowance is an amount that management believes
   will be adequate to absorb possible losses on existing loans that may become
   uncollectible, based on evaluations of the collectibility of loans and prior
   loan loss experience.  The evaluations take into consideration such factors
   as changes in the nature and volume of the loan portfolio, overall portfolio
   quality, review of specific problem loans, and current economic conditions
   that may affect the borrowers' ability to pay.

   Accrual of interest is discontinued on a loan when management believes,
   after considering economic and business conditions and collection efforts,
   that the borrower's financial condition is such that collection of interest
   is doubtful. Classification of a loan as nonaccrual is not necessarily
   indicative of a potential loss of principal.

   The Bank adopted SFAS No. 114, "Accounting by Creditors for Impairment
   of a Loan," on January 1, 1995.  Under the new standard, a loan is
   considered impaired, based on current information and events, if it is
   probable that the Bank will be unable to collect the scheduled payments of
   principal or interest when due according to the contractual terms of the
   agreement.  The measurement of impaired loans is generally based on the
   present value of expected future cash flows discounted at the historical
   effective interest rate, except that all collateral-dependent loans are
   measured for impairment based on the fair value of the collateral.  The
   adoption of SFAS No. 114 resulted in no change to the allowance for loan
   losses at January 1, 1995.

   In October 1994, the Financial Accounting Standards Board (FASB) issued
   SFAS No. 118, "Accounting by Creditors for Impairment of a Loan - Income
   Recognition and Disclosures."  SFAS No. 118 amends SFAS No. 114 to allow a
   creditor to use existing methods for recognizing interest income on an
   impaired loan, rather than methods prescribed in SFAS No. 114.

   LOAN ORIGINATION FEE INCOME - Non-refundable fees and costs associated
   with originating or acquiring loans is recognized over the lives of the
   related loans as an adjustment to interest income.

   BANK PREMISES AND EQUIPMENT - Bank premises and equipment are stated at
   cost, less accumulated depreciation computed on the straight-line method
   over the estimated useful lives of the assets.  Gains and losses on assets
   retired or otherwise disposed of are reflected in earnings and the cost and
   related accumulated depreciation are removed from the accounts. 
   Maintenance, repairs and minor improvements are expensed as incurred.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

   OTHER REAL ESTATE - Other real estate consists of properties acquired
   by or in lieu of foreclosure.  These assets are carried at the lower of fair
   value minus estimated costs to sell or cost.  Cost at the time of
   foreclosure is the fair value of the asset foreclosed.  If the fair value of
   the asset minus the estimated cost to sell the asset is less than the cost
   of the asset, the resulting loss is charged to the allowance for loan
   losses.  After foreclosure, if the fair value minus estimated costs to sell
   the property becomes less than its cost, the deficiency is charged to the
   provision for losses on other real estate owned or charged directly to the
   asset.  Costs relating to the development and improvement of the property
   are capitalized, whereas those relating to holding the property for sale are
   charged to expense.

   INCOME TAXES - The Bank accounts for income taxes in accordance with
   Statement of Financial Accounting Standard No. 109 (SFAS 109), Accounting
   for Income Taxes.  Under SFAS 109, the asset and liability method is used in
   accounting for income taxes.  Under this method, deferred tax assets and
   liabilities are determined based on differences between financial reporting
   and tax bases of assets and liabilities and are measured using the enacted
   marginal tax rates. The effect on deferred income taxes of a change in tax
   rates is recognized in income in the period that includes the enactment
   date.

   PER SHARE COMPUTATIONS - The income per share computations are based on
   the weighted average number of common shares outstanding during the year. 
   The average number of shares outstanding was 316,332 for the years ended
   December 31, 1995 and 1994.

   STATEMENT OF CASH FLOWS - For purposes of reporting cash flows, cash
   and cash equivalents include cash on hand, amounts due from banks, and
   federal funds sold.  Generally, federal funds are purchased and sold for
   one-day periods.

   The Bank maintains its due from banks and federal funds sold with
   correspondent banking relationships as determined by the Bank's board of
   directors.  At December 31, 1995 the primary correspondent bank was Barnett
   Banks, Inc.

   RECLASSIFICATION - Certain items in the 1994 financial statements have
   been reclassified to conform with the presentation in the 1995 financial
   statements.

   The Bank's lending is concentrated in the West Central Florida market.
   Although the Bank has a diversified loan portfolio, its debtors' ability to
   honor their contracts is substantially dependent upon the general economic
   conditions of the region.

   Loans on which accrual of interest has been discontinued amounted to
   approximately $87,700 and $91,000 at December 31, 1995 and 1994,
   respectively. If interest on those loans had been accrued, such income would
   have approximated $2,000 and $11,400 for 1995 and 1994, respectively.

   recorded investment in loans for which impairment has been recognized in
   accordance with SFAS No. 114 and 118 totaled approximately $195,000, of
   which 100% related to loans that were individually identified and measured
   for impairment with a valuation allowance of $19,500.  For the year ended
   December 31, 1995 the average recorded investment in impaired loans was

8. RELATED PARTY TRANSACTIONS:

   In the course of its business, the Bank has granted loans to directors
   of the Bank and to their related interests.  As of December 31, 1995 and
   1994, loans aggregating approximately $596,000 and $716,000, respectively,
   were outstanding to such parties.

9.  REGULATORY REQUIREMENTS:


    State banking regulations limit the amount of dividends that may be
    paid without the prior approval of the Bank's regulatory agency.  In
    accordance with Florida Banking regulations, the Bank transferred $92,999
    and $76,872 in 1995 and 1994, respectively, from retained earnings to
    additional paid-in capital during 1994.

    The current guidelines require the Bank to maintain total and tier-one
    capital of 8% and 4%, respectively, and a leverage ratio of 3% as of
    December 31, 1995. At December 31, 1995, the Bank's total risk-based
    capital, tier-one capital and leverage ratios were in excess of the amounts
    required.


10. COMMITMENTS AND CONTINGENCIES:

    In the normal course of business, the Bank has various outstanding
    commitments to extend credit that are not reflected in the accompanying
    financial statements.  At December 31, 1995 and 1994, commitments to extend
    credit and standby letters of credit aggregated approximately $1,943,000
    and $1,914,000, respectively.  The Bank's exposure to credit loss in the
    event of non-performance by the other party to the financial instrument
    for loan commitments and standby letters of credit is represented by the
    contractual amounts of those instruments.  The Bank uses the same credit
    policies in making commitments and conditional obligations as it does for
    on-balance-sheet instruments.

    Since certain of the loan commitments may expire without being drawn
    upon, the total commitment amount does not necessarily represent future
    cash requirements.  The Bank evaluates each borrower's credit worthiness on
    a case-by-case basis.  The amount of collateral obtained, if deemed
    necessary by the Bank upon extension of credit, is based on management's
    credit evaluation of the counterparty.  Collateral held varies, but may
    include real estate, autos, boats, inventory, receivables and deposit
    accounts.

    Standby letters of credit are conditional commitments issued by the
    Bank to guarantee the performance of a customer to a third party.  The
    credit risk involved in issuing letters of credit is essentially the same
    as that involved in extending loan facilities to customers.  There are no
    significant concentrations of credit risk with any individual counterparty
    to originate loans.

    The Bank is involved in legal proceedings primarily involving the
    recovery of loans previously charged off or adequately provided for in the
    allowance for loan losses. Management, after a review of all litigation
    with counsel, believes that the resolution of these matters will not have a
    material effect on the financial position and results of operations of the
    Bank.

11.  FAIR VALUES OF FINANCIAL INSTRUMENTS:

     SFAS No. 107, "Disclosures About Fair Value of Financial Instruments,"
     requires that the bank disclose estimated fair values for its financial
     instruments. Fair value is defined as the price at which a financial
     instrument could be liquidated in an orderly manner over a reasonable time
     period under present market conditions.  Fair values estimates, methods
     and assumptions are set forth below for the Bank's financial instruments.

     CASH, DUE FROM BANK AND FEDERAL FUNDS SOLD - For cash, due from banks
     and federal funds sold, the carrying amount is a reasonable estimate of
     fair value.

     INVESTMENT SECURITIES -  The fair value of investments securities is
     estimated based on bid prices published in financial newspapers or bid
     quotations received from securities dealers.

     LOANS - The estimated fair value of the Bank's performing fixed rate
     loans was calculated by discounting contractual cash flows adjusted for
     current prepayment estimates.  The discount rates were based on the
     interest rate charged to current customers for comparable loans.  The
     Bank's performing adjustable rate loans reprice frequently at current
     market rates.  Therefore, the fair value of these loans has been estimated
     to be approximately equal to their carrying amount.

     The impact of delinquent loans on the estimation of the fair values
     described above is not considered to have a material effect and,
     accordingly, delinquent loans have been disregarded in the valuation
     methodologies used.

     DEPOSIT LIABILITIES - The fair value of deposits with no stated
     maturity, such as demand, NOW, money market and savings is equal to the
     amount payable on demand as of December 31, 1995.  The fair value of time
     deposits is estimated using the rates currently offered for deposits of
     similar remaining maturities.

     COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTERS OF CREDIT- The fair
     value of commitments to extend credit is estimated using the fees
     currently charged to enter into similar agreements, taking into account
     the remaining terms of the agreements and the present creditworthiness of
     the counterparties.  For fixed rate loan commitments, fair value also
     considers the difference between current levels of interest rates and the
     committed rates.  The fair value of letters of credit is based on fees
     currently charged for similar agreements or on the estimated cost to
     terminate them or otherwise settle the obligations with the
     counterparties.

    The value estimates are based on existing on- and off-balance sheet
    financial instruments without attempting to estimate the value of
    anticipated future business and the value of assets and liabilities that are
    not considered financial instruments.  Other significant assets and
    liabilities that are not considered financial assets or liabilities include
    deferred tax assets and property, plant and equipment.  In addition, the tax
    ramifications related to the realization of the unrealized gains and losses
    for investment securities can have a significant effect on fair value
    estimates and have not been considered in many of the estimates.

    LIMITATIONS - The fair value estimates are made at a discrete point in
    time based on relevant market information and information about the
    financial instrument.  Quoted market prices, when available, are used as the
    measure of fair value.  When quoted market prices are not available, fair
    value estimates have been based on judgments regarding future expected loss
    experience, current economic conditions, risk characteristics of various
    financial instruments, and other factors.  These estimates are inherently
    subjective, involving uncertainties and matters of significant judgment,
    and, therefore, may not be indicative of the value that could be realized in
    a current market exchange. Changes in assumptions could significantly affect
    the estimates.

12. RISKS AND UNCERTAINTIES:

    The earnings of the Bank are dependent primarily upon the level of net
    interest income, which is the difference between interest earned on its
    interest earned assets, such as loans and investments and the interest paid
    on its interest-bearing liabilities, such as deposits.  Accordingly, the
    operations of the Bank are subject to risks and uncertainties surrounding
    its exposure to changes in the interest rate environment.
    
    The Bank's lending is concentrated in the West Central Florida market.
    Although the Bank has a diversified loan portfolio, its debtors' ability to
    honor their contracts is substantially dependent upon the general economic
    conditions of the region.
    
    The financial statements of the Bank are prepared in conformity with
    generally accepted accounting principles that require management to make
    estimates and assumptions that affect the reported amounts of assets and
    liabilities and disclosures of contingent assets and liabilities at the date
    of the financial statements and the reported amounts of revenues and
    expenses during the reported period.  Actual results could differ from these
    estimates.
    
    Significant estimates are made by management in determining the
    allowance for loan losses and carrying values of other real estate assets. 
    Consideration is given to a variety of factors in establishing these
    estimates including current economic conditions, diversification of the loan
    portfolio, delinquency statistics, results of internal loan reviews,
    borrowers' perceived financial and managerial strengths, the adequacy of
    underlying collateral, if collateral dependent, or present value of future
    cash flows and other relevant factors. Since the allowance for possible loan
    losses and the carrying value of other real estate assets is dependent, to a
    great extent, on the general economic conditions and other conditions that
    may be beyond the Bank's control, it is at least reasonably possible that
    the estimates of the allowance for possible loan losses and the carrying
    values of the other real estate assets could differ materially in the near
    term.


13. SUBSEQUENT EVENT:

    On February 12, 1996, Lake State Bank entered into a definitive
    agreement and plan of merger with South Trust Bank of Florida, N.A. 
    Finalization of this merger is contingent upon regulatory and Lake State
    Bank shareholder approval.
   
    Immediately prior to the effective date of the merger, each Lake State
    Bank share outstanding shall be converted into the right to receive a
    predetermined percentage of one share of common stock of South Trust Bank. 
    (This percentage is known as the conversion ratio.)

LAKE STATE BANK
NOTES TO CONDENSED UNAUDITED FINANCIAL STATEMENTS

1. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS:

   
   In October 1994, the FASB issued SFAS 119, "Disclosure about Derivative
   Financial Instruments and Fair Value of Instruments."  SFAS 119 requires
   disclosures about derivative financial instruments - futures, forward, swap,
   and option contracts, and other financial instruments with similar
   characteristics.  It also amends existing requirements of SFAS 105,
   "Disclosure of Information about Financial Instruments with
   Off-Balance-Sheet Risk and Financial Instruments with Concentrations of
   Credit Risk," and SFAS 107.  SFAS 119 requires disclosures about amounts,
   nature, and terms of derivative financial instruments that are not subject
   to SFAS 105 because they do not result in off-balance-sheet risk of
   accounting loss.  It requires that a distinction be made between financial
   instruments held or issued for trading purposes (including dealing and other
   trading activities measured at fair value with gains and losses recognized
   in earnings) and financial instruments held or issued for purposes other
   than trading.  SFAS 119 is effective for financial statements for fiscal
   years beginning after December 15, 1995, with earlier application
   encouraged.
    

   
   As SFAS 119 relates only to disclosure issues, no impact on the financial
   position of the Bank is expected upon adoption of this pronouncement.
    

   
   SFAS 121, "Accounting for the Impairment of Long-Lived Assets and for
   Long-Lived Assets to Be Disposed of," issued by the FASB in March 1995, is
   effective for the Bank for fiscal years beginning on or after December 15,
   1995.  SFAS 121 requires that long-lived assets and certain identifiable
   intangibles to be held and used by an entity, be reviewed for impairment
   whenever events or changes in circumstances indicate that the carrying
   amount of an asset may not be recoverable.  In performing the review for
   recoverability, the entity should estimate the future cash flows expected to
   result from the use of the asset and its eventual disposition.  If the sum
   of the expected future cash flow (undiscounted and without interest charges)
   is less than the carrying amount of the asset, an impairment loss is
   recognized.  Measurement of an impairment loss for long-lived assets and
   identifiable intangibles that an entity expects to hold and use should be
   based on the fair value of the asset.  Management has not determined the
   impact of SFAS 121 on the Bank's financial statements.
    

   
   In May 1995, the Financial Accounting Standards Board issued SFAS 122,
   "Accounting for Mortgage Servicing Rights." SFAS 122 requires companies that
   engage in mortgage banking activities to allocate the total cost of the
   mortgage loans it requires or originates and then sells with servicing
   rights retained between the estimated fair value of the loans and the
   capitalized mortgage servicing rights, if practical.  SFAS 122 also requires
   that capitalized mortgage servicing rights be assessed for impairment based
   on the fair value of those rights.  SFAS 122 applies prospectively to fiscal
   years beginning after December 15, 1995.  The adoption of the provisions of
   SFAS 122 is not expected to have a material impact on the financial position
   of the Bank upon adoption.

NOTES TO CONDENSED UNAUDITED FINANCIAL STATEMENTS, CONTINUED

1. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS, CONTINUED:

   
   In October 1995, the FASB issued SFAS 123, "Accounting for Stock-Based
   Compensation," effective for fiscal years beginning after December 15, 1995.
   SFAS 123 requires a fair value-based method of accounting for stock-based
   compensation.  Since the Bank does not utilize any stock-based compensation
   plans, SFAS 123 is not expected to have a material impact on the financial
   position or results of operations of the Bank.

                 NOW, THEREFORE, in consideration of the premises and the
mutual covenants, representations, warranties and agreements herein contained,
the parties agree that LSB will be merged with and into ST-Bank and that the

the Articles of Association and Bylaws of the Surviving Corporation, the
persons who shall serve as directors and executive officers, as the case may

net unrealized holding gains (losses) on available for sale securities of
$1,053,564.

                          (h)     The Surviving Corporation shall have trust 
powers.

                          (i)     The Articles of Association under which the

ST-Bank.

         Section 1.2      Effect of Merger.  (a) At the Effective Time of the
Merger, LSB shall be merged with and into ST-Bank and the separate existence of
LSB shall cease.  The Articles of Association and Bylaws of ST-Bank, as in
effect on the date hereof and as otherwise amended prior to the Effective Time
of the Merger, shall be the Articles of Association and the Bylaws of the
Surviving Corporation until further amended as provided therein and in
accordance with applicable law.  The Surviving Corporation shall have all the
rights, privileges, immunities and powers and shall be subject to all the

servicemarks of LSB.  All property (real, personal and mixed) and all debts on
whatever account, including subscriptions to shares, and all choses in action,
all and every other interest, of or belonging to or due to each of the

to and vested in the Surviving Corporation without further act or deed.  The
title to any real estate, or any interest therein, vested in any of the
constituent corporations shall not revert or be in any way impaired by reason
of the Merger.  The Surviving Corporation shall thenceforth be responsible and

treated in the Merger as specified in Article II.

         Section 1.3      Further Assurances.  From and after the
Effective Time of the Merger, as and when requested by the Surviving
Corporation, the officers and directors of LSB last in office shall execute and
deliver or cause to be executed and delivered in the name of LSB such deeds and
other instruments and take or cause to be taken such further or other actions
as shall be necessary in order to vest or perfect in or confirm of record or
otherwise to the Surviving Corporation title to and possession of all of the

                                  ARTICLE II

                   CONVERSION OF CONSTITUENTS' CAPITAL SHARES


         Section 2.1      Manner of Conversion of LSB 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 the holder of any shares
of common stock of LSB, par value $8.00 (the "LSB Shares"):

         (a)     All LSB Shares which are held by LSB as treasury stock, if
                 any, 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 2.2 hereof and except
                 with regard to Dissenting LSB Shares (as hereinafter defined),
                 each LSB Share outstanding immediately prior to the Effective
                 Time of the Merger shall be converted into the right to
                 receive .84 of one share of common stock of SouthTrust (and
                 the rights associated therewith issued pursuant to a Rights
                 Agreement dated February 22, 1989 between SouthTrust and
                 Mellon Bank, N.A.) (together, the "SouthTrust Shares") (such
                 fraction, as may be adjusted, as provided herein, being
                 hereinafter referred to as the "Conversion Ratio").  The
                 Conversion Ratio, including the number of SouthTrust Shares
                 issuable in the Merger, shall be subject to an appropriate
                 adjustment in the event of any stock split, reverse stock
                 split, dividend payable in SouthTrust Shares, reclassification
                 or similar distribution whereby SouthTrust issues SouthTrust
                 Shares or any securities convertible into or exchangeable for
                 SouthTrust Shares without receiving any consideration in
                 exchange therefor, provided that the record date of such
                 transaction is a date after the date of the Agreement and
                 prior to the Effective Time of the Merger.

         (c)     Each outstanding LSB Share, the holder of which has demanded
                 and perfected his demand for payment of the "fair or
                 appraised" value of such share in accordance with Section
                 658.44 of the Florida Code (the "Dissent Provisions"), to the
                 extent applicable, and has not effectively withdrawn or lost
                 his right to such appraisal (the "Dissenting LSB 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.  LSB shall give SouthTrust prompt
                 notice upon receipt by LSB of any written objection to the
                 Merger and any written demands for payment of the



                                     A-3

<PAGE>   91

                 fair or appraised value of LSB Shares, and of withdrawals of
                 such demands, and any other instruments provided to LSB
                 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 LSB Shares held by such Dissenting
                 Shareholder shall receive payment therefor from ST-Bank, as
                 escrow agent (the "Escrow Agent"), on behalf of LSB out of
                 funds provided to the Escrow Agent by LSB in accordance with
                 the provisions of Section 2.1(d) (but only after the amount
                 thereof shall have been agreed upon or at the times and in the
                 amounts required by the Dissent Provisions) and all of such
                 Dissenting Shareholder's LSB Shares shall be canceled.
                 Neither LSB nor the Surviving Corporation shall, except with
                 the prior written consent of ST-FL,  voluntarily  make any
                 payment with 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 or appraised value, the LSB 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.

         (d)     With respect to each Dissenting Shareholder, on or immediately
                 prior to the Effective Time of the Merger, LSB 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 2.2) 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 LSB Shares converted pursuant to
the Merger, 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 sales price of such SouthTrust Shares, as reported by The NASDAQ
Stock Market National Market System ("NASDAQ") on the last trading 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 Securities Exchange Act of 1934, the last sales or closing
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)  As promptly as
practicable after the Effective Time of the Merger, SouthTrust shall send or
cause to be sent to each former holder of record of LSB Shares transmittal
materials (the "Letter of Transmittal") for use in exchanging their
certificates formerly representing LSB Shares for the consideration provided
for in this Agreement.  As soon as practicable after receipt of properly
completed Letters of Transmittal, and stock certificates evidencing the LSB
Shares held by the former holders of the LSB Shares, SouthTrust shall cause the
appropriate number of SouthTrust Shares to be issued to the former holders of
LSB Shares submitting such Letters of Transmittal.  Amounts that would have
been payable to Dissenting Shareholders for LSB Shares but for the fact of
their dissent in accordance with the provisions of Section 2.1(c) hereof shall
be administered in accordance with the Dissent Provisions.

                 (b)      At the Effective Time of the Merger, the stock
transfer books of LSB shall be closed as to holders of LSB Shares immediately
prior to the Effective Time of the Merger and no transfer of LSB Shares by any
such holder shall thereafter be made or recognized and each outstanding
certificate formerly representing LSB Shares shall, without any action on the
part of any holder thereof, no longer represent LSB Shares.  If, after the
Effective Time of the Merger, certificates are properly presented to
SouthTrust, such certificates shall be exchanged for the consideration
contemplated by this Agreement into which the LSB 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 LSB Shares is unable to deliver the certificate
which represents such holder's LSB Shares, ST-FL, in the absence of actual
notice that any LSB Shares theretofore represented by any such certificate have
been acquired by a bona fide purchaser, shall 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 ST-FL that any such certificate has 
                          been lost,wrongfully taken or destroyed;

                 (ii)     Such security and indemnity as may be reasonably
                          requested by ST-FL to indemnify and hold ST-FL
                          harmless; and

                 (iii)    Evidence to the satisfaction of ST-FL that such 
                          holder is the owner of the LSB 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 LSB 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 LSB 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.  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 to the holder of any unsurrendered
certificate or certificates representing LSB Shares, and neither SouthTrust nor
ST-FL shall be obligated to deliver any of the consideration contemplated by
this Agreement, any amount of cash representing fractional SouthTrust Shares or
any such dividend or other distribution with respect to SouthTrust Shares until
such holder shall surrender the certificate or certificates representing LSB
Shares as provided for by the Agreement.  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.

         Section 2.4      Laws of Escheat.  If any of the consideration due or
other payments to be paid or delivered to the holders of LSB 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 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 LSB, SouthTrust,
ST-FL, ST-Bank, nor any other person acting on their behalf shall be liable to
a holder of LSB 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.

         Section 2.5      Consideration.  SouthTrust, on behalf of ST-FL, 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.

                     REPRESENTATIONS AND WARRANTIES OF LSB


         LSB hereby represents and warrants to ST-Bank, ST-FL and SouthTrust as

business is now being conducted, and LSB is duly licensed or qualified to do
business in Florida and elsewhere where the nature of the business conducted by
it or the character or location of the properties and assets owned or leased by

foreign governmental, regulatory and other authorizations, permits and licenses

and LSB does not have any interest in any partnership or joint venture. For
purposes of this Agreement, a "subsidiary" means any corporation or other

                 (d)      The minute books of LSB contain complete and accurate

have been duly authorized and validly issued and all such shares are fully paid
and nonassessable.  As of the date hereof, there are no outstanding options,
warrants, commitments, or other rights or instruments to purchase or acquire

         Section 3.3      Financial Statements; Filings.  (a)  LSB has
previously delivered to SouthTrust copies of the financial statements of LSB as

the Call Reports of LSB as of and for the years ended 1993, 1994 and 1995, and
LSB shall deliver to SouthTrust, as soon as practicable following the
preparation of additional Call Reports for each subsequent calendar quarter (or
other reporting period) or year of LSB, the Call Reports of LSB as of and for
each such subsequent calendar quarter (or other reporting period) or year (such
Call Reports, unless otherwise indicated, being hereinafter referred to

                 (c)      Each of the Financial Statements of LSB and each of
the Call Reports of LSB (including the related notes, where applicable) have
been or will be prepared in all material respects in accordance with generally
accepted accounting principles or regulatory accounting principles, whichever
is applicable, which principles have been or will be consistently applied
during the periods involved, except as otherwise noted therein, and the books
and records of LSB have been, are being, and will be maintained in all material
respects in accordance with applicable legal and accounting requirements
consistent with past practices and reflect only actual transactions.  Each of

heretofore delivered or made available, or caused to be delivered or made
available, to SouthTrust all reports and filings made or required to be made by
LSB, with the Regulatory Authorities, and will from time to time hereafter
furnish to SouthTrust, upon filing or furnishing the same to the Regulatory
Authorities, all such reports and filings made after the date hereof with the
Regulatory Authorities.  As of the respective dates of such reports and

circumstances under which they were made, not misleading.

                 (e)      Except as reflected on Disclosure Schedule 3.3(e)
hereto, since December 31, 1995, LSB has not incurred any obligation or
liability (contingent or otherwise) that has or might reasonably be expected to
have, individually or in the aggregate, a material adverse effect on the
Condition of LSB except obligations and liabilities (i) which are accrued or
reserved against in the Financial Statements of LSB or the Call Reports of LSB,
or reflected in the notes thereto, (ii) which were incurred after December 31,
1995, in the ordinary course of business consistent with past practices, or
(iii) which are contemplated by this Agreement or incurred with the written
consent of SouthTrust.

power and authority to execute and deliver this Agreement and, subject to the

Regulatory Authorities, to consummate the transactions contemplated hereby.
The Board of Directors of LSB has duly and validly approved this Agreement and
the transactions contemplated hereby, has authorized the execution and delivery
of this Agreement, has directed that this Agreement and the transactions
contemplated hereby be submitted and recommended to LSB' shareholders for

against LSB in accordance with its terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors rights generally and except
that the availability of the equitable remedy of specific performance or
injunctive relief is subject to the discretion of the court before which any
proceeding may be brought.

                 (b)      Except as set forth in Disclosure Schedule 3.6(b),
neither the execution and delivery of this Agreement by LSB nor the

a default) under, result in the termination of, accelerate the performance

or directors, has employed any broker or finder or incurred any liability for
any broker's fees, commissions or finder's fees in connection with any of the

irrespective of whether the Merger is closed.

         Section 3.9      Absence of Certain Changes or Events.  Except as
occasioned by this Agreement or with the consent of SouthTrust, since December

in the Condition of LSB which has had, or is reasonably likely to have, a
material adverse effect on the Condition of LSB or on LSB generally, including,
without limitation any change in the administration or supervisory standing or
rating of LSB with any Regulatory Authority, and no fact or condition exists as
of the date hereof which might reasonably be expected to cause any such event
or change in the future.

         Section 3.10     Legal Proceedings; Etc.  Except as set forth in
Disclosure Schedule 3.10, LSB is not a party to any, and there are no pending
or, to the knowledge of LSB, threatened, judicial, administrative, arbitral or

contemplated by this Agreement and, to the knowledge of LSB as of the date
hereof, there is no material proceeding, claim, action or governmental
investigation against LSB; no judgment, decree, injunction, rule or order of
any court, governmental department, commission, agency, instrumentality or
arbitrator is outstanding against LSB which has a material adverse effect on
the Condition of LSB; there is no default by LSB under any material contract or

order or memorandum in writing by or with any Regulatory Authority restricting
the operations of LSB and LSB has not been advised by any Regulatory Authority
that any such Regulatory Authority is contemplating issuing or requesting the
issuance of any such order or memorandum in the future.

         Section 3.11     Taxes and Tax Returns.  LSB has previously delivered
or made available to SouthTrust copies of the federal income tax returns of LSB
for the years 1991, 1992, 1993 and 1994 and all schedules and exhibits thereto,
and, to the knowledge of LSB such returns have not been subjected to an audit
by the Internal Revenue Service.  Except as reflected in Disclosure Schedule
3.11, to its knowledge, LSB has duly filed in correct form all material
federal, state and local information returns and tax returns required to be
filed on or prior to the date hereof, and LSB has duly paid or made adequate
provisions for the payment of all taxes and other governmental charges which
have been incurred or are due or claimed to be due from LSB by any federal,
state or local taxing authorities (including, without limitation, those due in
respect of the properties, income, business, capital stock, deposits,
franchises, licenses, sales and payrolls of LSB other than taxes and other
charges which (i)(A) are not yet delinquent or (B) are being contested in good
faith or (ii) have not been finally determined.  The amounts set forth as
liabilities for taxes on the Financial Statements of LSB and the Call Reports
of LSB are sufficient, in the aggregate, for the payment of all unpaid federal,
state and local taxes (including any interest or penalties thereon), whether or
not disputed, accrued or applicable, for the periods then ended, and have been
computed in accordance with generally accepted accounting principles consistent
with past practices.  LSB is not responsible for the taxes of any other person
other than LSB, under Treasury Regulation 1.1502-6 or any similar provision of
federal, state or foreign law.

         Section 3.12     Employee Benefit Plans.  (a) LSB does not maintain
any "employee benefit plan," as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), except as
described in Disclosure Schedule 3.12(a).

                 (b)      LSB (or any pension plan maintained by it) has not
incurred any liability to the Pension Benefit Guaranty Corporation ("PBGC") or
the Internal Revenue Service with respect to any pension plan qualified under
Section 401 of the Code, except liabilities to the PBGC pursuant to Section
4007 of ERISA, all which have



                                     A-8

<PAGE>   96


been fully paid.  No reportable event under Section 4043(b) of ERISA (including
events waived by PBGC regulation) has occurred with respect to any such pension
plan.

                 (c)      LSB has not incurred any material liability under
Section 4201 of ERISA for a complete or partial withdrawal from, or agreed to
participate in, any multi-employer plan as such term is defined in Section
3(37) of ERISA.
                 (d)      All "employee benefit plans," as defined in Section
3(3) of ERISA, that are maintained by LSB comply in both form and operation, in
all material respects, with ERISA and the Code that are applicable, or intended
to be applicable, to such "employee benefit plans."  LSB has no any material
liability under any such plan that is not reflected in the Financial Statements
of LSB or the Call Reports of LSB.

                 (e)      To the best knowledge of LSB, no prohibited
transaction (which shall mean any transaction prohibited by Section 406 of
ERISA and not exempt under Section 408 of ERISA) has occurred with respect to
any employee benefit plan maintained by LSB (i) which would result in the
imposition, directly or indirectly, of a material excise tax under Section 4975
of the Code or a material civil penalty under Section 502(i) of ERISA, or (ii)
the correction of which would have a material adverse effect on the Condition
of LSB; and, to the best knowledge of LSB no actions have occurred which could
result in the imposition of a penalty under any section or provision of ERISA.

                 (f)      No employee benefit plan which is a defined benefit
pension plan has any "unfunded current liability," as that term is defined in
Section 302(d)(8)(A) of ERISA, and the present fair market value of the assets
of any such plan exceeds the plan's "benefit liabilities," as that term is
defined in Section 4001(a)(16) of ERISA, when determined under actuarial
factors that would apply if the plan terminated in accordance with all
applicable legal requirements.

                 (g)      Neither the execution and delivery of this Agreement
nor the consummation of the transactions contemplated hereby will (i) result in
any material payment (including, without limitation, severance, unemployment
compensation, golden parachute or otherwise) becoming due to any director or
any officer or employee of LSB under any benefit plan or otherwise, (ii)
materially increase any benefits otherwise payable under any benefit plan or
(iii) result in any acceleration of the time of payment or vesting of any such
benefits to any material extent.

         Section 3.13     Title and Related Matters.  (a)  Except as set forth
in Disclosure Schedule 3.13(a) and except with respect to "other real estate
owned", LSB has good title, and as to owned real property, has good and
marketable title in fee simple absolute, to all assets and properties, real or
personal, tangible or intangible, reflected as owned by it or carried under its
name on the Financial Statements of LSB, or the Call Reports of LSB or acquired
subsequent thereto (except to the extent that such assets and properties have
been disposed of for fair value in the ordinary course of business since
December 31, 1995), free and clear of all liens, encumbrances, mortgages,
security interests, restrictions, pledges or claims, except for (i) those
liens, encumbrances, mortgages, security interests, restrictions, pledges or
claims reflected in the Financial Statements of LSB and the Call Reports of LSB
or incurred in the ordinary course of business after December 31, 1995, (ii)
statutory liens for amounts not yet delinquent or which are being contested in
good faith, and (iii) liens, encumbrances, mortgages, security interests,
pledges, claims and title imperfections that are not in the aggregate material
to the Condition of LSB.

                 (b)      All agreements pursuant to which LSB leases,
subleases or licenses material real or material personal properties from others
are valid, binding and enforceable in accordance with their respective terms,
and there is not, under any of such leases or licenses, any existing default or
event of default, or any event which with notice or lapse of time, or both,
would constitute a default or force majeure, or provide the basis for any other
claim of excusable delay or nonperformance, except for defaults which
individually or in the aggregate would not have a material adverse effect on
the Condition of LSB.

                 (c)      Other than "other real estate owned", (i) all of the
buildings, structures and fixtures owned, leased or subleased by LSB, are in
good operating condition and repair, subject only to ordinary wear and tear
and/or minor defects which do not interfere with the continued use thereof in
the conduct of normal operations, and (ii) all of the material personal
properties owned, leased or subleased by LSB, are in good operating condition
and repair, subject only to ordinary wear and tear and/or minor defects which
do not interfere with the continued use thereof in the conduct of normal
operations.

         Section 3.14     Real Estate.  (a) Disclosure Schedule 3.14(a)
identifies and sets forth a complete legal description for each parcel of real
estate or interest therein owned, leased or subleased by LSB or in which LSB
has any ownership or leasehold interest; provided that "other real estate
owned" or otherwise held in the loan portfolio of LSB is only reasonably
identified on Disclosure Schedule 3.14(a).

<PAGE>   97


                 (b)      Disclosure Schedule 3.14(b) lists or otherwise
describes each and every written or oral lease or sublease under which LSB is
the lessee of any real property and which relates in any manner to the
operation of the businesses of LSB.  All rentals due under such leases have
been paid and there exists no material default under the terms of any lease and
no event has occurred which, upon the passage of time or giving of notice, or
both, would result in any event of default or prevent LSB, from exercising and
obtaining the benefits of any options or other rights contained therein, except
for defaults which individually or in the aggregate would not have a material
adverse effect on the Condition of LSB.  Except as set forth in Disclosure
Schedule 3.14(b), LSB has all right, title and interest as a lessee under the
terms of each lease or sublease, free and clear of all liens, claims or
encumbrances (other than the rights of the lessor), and all such leases are
valid and in full force and effect.  LSB has the right under each such lease
and sublease to occupy, use, possess, and control all property leased or
subleased by LSB and, as of the Effective Time of the Merger, shall have the
right to transfer each lease or sublease pursuant to this Agreement.

                 (c)      LSB has not violated, and is not currently in
violation of, any law, regulation or ordinance relating to the ownership or use
of the real estate and real estate interests described in Disclosure Schedules
3.14(a) and 3.14(b) including, but not limited to any law, regulation or
ordinance relating to zoning, building, occupancy, environmental or comparable
matter which individually or in the aggregate would have a material adverse
effect on the Condition of LSB.

                 (d)      Except as set forth in Disclosure Schedule 3.14(d),
as to each parcel of real property owned or used by LSB, LSB has not received
notice of any pending or, to the knowledge of LSB threatened condemnation
proceedings, litigation proceedings or mechanics or materialmen's liens.

         Section 3.15     Environmental Matters.

                 (a)      LSB and the Participation Facilities (as defined
below) are, and have been, in compliance with all applicable laws, rules,
regulations, standards and requirements of the United States Environmental
Protection Agency and all state and local agencies with jurisdiction over
pollution or protection of the environment, except for violations which,
individually or in the aggregate, will not have a material adverse effect on
the Condition of LSB.

                 (b)      LSB has not received notice of any litigation pending
or threatened before any court, governmental agency or board or other forum in
which LSB or any Participation Facility has been or, with respect to threatened
litigation may be, named as defendant (i) for alleged noncompliance (including
by any predecessor), with any Environmental Law (as defined below) or (ii)
relating to the release of an amount of a reportable quantity or more into the
environment of any Hazardous Material (as defined below) or oil, whether or not
occurring or on a site owned or leased or operated by LSB or any Participation
Facility, except for such litigation pending or threatened that will not,
individually or in the aggregate, have a material adverse effect on the
Condition of LSB.

                 (c)      To the knowledge of LSB, there is no reasonable basis
for any litigation of a type described in 3.15(b), of this Agreement, except as
will not have, individually or in the aggregate, a material adverse effect on
the Condition of LSB.

                 (d)      During the period of (i) ownership or operation by
LSB of any of its current properties, or (ii) participation by LSB in the
management of any Participation Facility, there have been no releases of
Hazardous Material or oil in, on, under or affecting such properties, except
where such releases have not and will not, individually or in the aggregate,
have a material adverse effect on the Condition of LSB.

                 (e)      "Environmental Law" means any applicable federal,
state or local law, statute, ordinance, rule, regulation, code, license,
permit, authorization, approval, consent, order, judgment, decree or injunction
relating to (i) the protection, preservation or restoration of the environment
(including, without limitation, air, water vapor, surface water, groundwater,
drinking water supply, surface soil, subsurface soil, plant and animal life or
any other natural resource), and/or (ii) the use, storage, recycling,
treatment, generation, transportation, processing, handling, labeling,
production, release or disposal of any substance presently listed, defined,
designated or classified as hazardous, toxic, radioactive or dangerous, or
otherwise regulated, whether by type or by substance as a component; "Hazardous
Material" means any pollutant, contaminant, or hazardous substance within the
meaning of the Comprehensive Environmental Response, Compensation, and
Liability Act, 42 U.S.C. Section  9601 et seq., or any similar federal, state
or local law; and "Participation Facility" means any facility in which LSB has
engaged in Participation in the Management of such facility, and, where
required by the context, includes the owner or operator of such facility, but
only with respect to such facility; "Participation in the Management" of a
facility has the meaning set forth in 40 C.F.R. Section  300.1100(c).

         Section 3.16     Commitments and Contracts.  Except as set forth in
Disclosure Schedule 3.16, LSB is not a party or subject to any of the following

<PAGE>   98


                 (a)      Any employment contract (including any agreement or
plan with respect to severance or termination pay liabilities or fringe
benefits) with any present or former officer, director, employee, including in
any such person's capacity as a consultant (other than those which either are
terminable at will without any further amount being payable thereunder or as a
result of such termination by LSB);

                 (b)      Any labor contract or agreement with any labor union;

                 (c)      Any contract covenants which limit the ability of LSB
to compete in any line of business or which involve any restriction of the
geographical area in which LSB may carry on its business (other than as may be
required by law or applicable regulatory authorities);

                 (d)      Any lease (other than real estate leases described on
Disclosure Schedule 3.14(b)) or other agreements or contracts with annual
payments aggregating $25,000 or more; or

                 (e)      Any other contract or agreement which would be
required to be disclosed in reports filed by LSB with the SEC or the FRB and
which has not been so disclosed.

         Section 3.17     Regulatory and Accounting Matters.  LSB has not
agreed to take any action or has any knowledge of any fact or has agreed to any
circumstance that would materially impede or delay receipt of any Consents of
any Regulatory Authorities referred to in this Agreement, including matters
relating to the Community Reinvestment Act and protests thereunder; and LSB has
not agreed to take any action or has knowledge of any fact or has agreed to any
circumstance that would materially impede the ability of SouthTrust to account
for the transactions contemplated by this Agreement as a pooling of interests.

         Section 3.18     Registration Obligations.  LSB is not under any
obligation, contingent or otherwise, which will survive the Merger, to register
any of its securities under the Securities Act of 1933 or any state securities
laws.

transactions contemplated hereby are not subject to or restricted by any
applicable state anti-takeover statute.

         Section 3.20     Insurance.  LSB is presently insured, and during each
of the past three calendar years has been insured, for reasonable amounts
against such risks as companies or institutions engaged in a similar business
would, in accordance with good business practice, customarily be insured.  To
the knowledge of LSB, the policies of fire, theft, liability and other
insurance maintained with respect to the assets or businesses of LSB provide
adequate coverage against loss, and the fidelity bonds in effect as to which
LSB is named an insured are sufficient for their purpose.  Such policies of
insurance are listed and described in Disclosure Schedule 3.20.

         Section 3.21     Labor.  No work stoppage involving LSB is pending as
of the date hereof or, to the knowledge of LSB, threatened.  LSB is not
involved in, or, to the knowledge of LSB, threatened with or affected by, any
proceeding asserting that LSB has committed an unfair labor practice or any
labor dispute, arbitration, lawsuit or administrative proceeding which might
reasonably be expected to have a material adverse effect on the Condition of
LSB.  No union represents or claims to represent any employees of LSB, and, to
the knowledge of LSB, no labor union is attempting to organize employees of
LSB.

         Section 3.22     Compliance with Laws.  LSB has conducted its business
in accordance with all applicable federal, foreign, state and local laws,
regulations and orders, and is in compliance with such laws, regulations and
orders, except for such violations or non-compliance, which when taken together
as a whole, will not have a material adverse effect on the Condition of LSB.
Except as disclosed in Disclosure Schedule 3.22, LSB:

                 (a)      Is not in violation of any laws, orders or permits
                          applicable to its business or the employees or agents
                          or representatives conducting its business, except
                          for violations which individually or in the aggregate
                          do not have and will not have a material adverse
                          effect on the Condition of LSB; and

                 (b)      Has not received a notification or communication from
                          any agency or department of federal, state or local
                          government or the Regulatory Authorities or the staff
                          thereof (i) asserting that LSB is not in compliance
                          with any laws or orders which such governmental
                          authority or Regulatory Authority enforces, where
                          such noncompliance is reasonably likely to have a
                          material adverse effect on the Condition of LSB, (ii)
                          threatening to revoke any permit, the revocation of
                          which is reasonably likely to have a material adverse
                          effect on the Condition of LSB, (iii) requiring LSB
                          to enter into any cease and desist order, formal
                          agreement, commitment or memorandum of understanding,
                          or to adopt any resolutions or similar undertakings,
                          or (iv) directing, restricting or limiting, or
                          purporting to direct,



                                     A-11

                          LSB, including, without limitation, any restrictions
                          on the payment of dividends.

         Section 3.23     Transactions with Management.  Except for (a)
deposits, all of which are on terms and conditions comparable to those made
available to other customers of LSB at the time such deposits were entered
into, (b) the agreements listed on Disclosure Schedule 3.16, and (c) the items
described on Disclosure Schedule 3.23, there are no contracts with or
commitments to present or former stockholders, directors, officers or employees
involving the expenditure of more than $1,000 as to any one individual,
including, any business directly or indirectly controlled by any such person,
or $5,000 for all such contracts or commitments in the aggregate for all such
individuals.

         Section 3.24     Proxy Materials.  None of the information relating to
LSB to be included in the Proxy Statement which is to be mailed to the
shareholders of LSB in connection with the solicitation of their approval of
this Agreement will, at the time such Proxy Statement is mailed or at the time
of the meeting of shareholders to which such Proxy Statement relates, be false
or misleading with respect to any material fact, or omit to state any material
fact, necessary in order to make a statement therein not false or misleading.

         Section 3.25     Deposit Insurance.  The deposit accounts of LSB are
insured by the Bank Insurance Fund in accordance with the provisions of the
Federal Deposit Insurance Act (the "Act"); LSB has paid all regular premiums
and special assessments and filed all reports required under the Act.

         Section 3.26     Untrue Statements and Omissions.  No representation
or warranty contained in Article III of this Agreement or in the Disclosure
Schedules of LSB contains any untrue statement of a material fact or omits to
state a material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

                          course of business, or (B) acquisitions of control by
                          LSB in a fiduciary capacity.

         Section 5.2      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 of this Agreement, LSB will cause one or more of its
designated representatives to confer on a regular and frequent basis with
representatives of SouthTrust and to report the general status of the ongoing
operations of LSB.  LSB will promptly notify SouthTrust of any material change
in the normal course of business or the operations or the properties of LSB,
any governmental complaints, investigations or hearings (or communications
indicating that the same may be contemplated) affecting LSB, the institution or
the threat of material litigation, claims, threats or causes of action
involving LSB, and will keep SouthTrust fully informed of such events.  LSB
will furnish to SouthTrust, promptly after the preparation and/or receipt by
LSB thereof, copies of its unaudited periodic financial statements and call
reports for the applicable periods then ended, and such financial statements
and call reports shall, upon delivery to SouthTrust, be treated, for purposes
of Section 3.3 hereof, as among the Financial Statements of LSB and the Call
Reports of LSB.

         Section 5.3      Access to Properties; Personnel and Records.  (a) So
long as this Agreement shall remain in effect, LSB shall permit SouthTrust or
its agents full access, during normal business hours, to the properties of LSB,

SouthTrust and to its internal auditors, loan review officers, attorneys,
accountants and other representatives, all books, papers and records relating
to the assets, stock, properties, operations, obligations and liabilities of
LSB, including all books of account (including the general ledger), tax
records, minute books of directors' and shareholders' meetings, organizational
documents, bylaws, contracts and agreements, filings with any regulatory
agency, examination reports, correspondence with regulatory or taxing
authorities, documents relating to assets, titles, abstracts, appraisals,
consultant's reports, plans affecting employees, securities transfer records
and stockholder lists, and any other assets, business activities or prospects
in which SouthTrust may have a reasonable interest, and LSB shall use its
reasonable best efforts to provide SouthTrust and its representatives access to
the work papers of LSB's accountants.  LSB shall not be required to provide
access to or to disclose information where such access or disclosure would
violate or prejudice the rights of any customer, would contravene any law,
rule, regulation, order or judgment or would violate any confidentiality
agreement; provided that LSB shall take all necessary steps to obtain Consents
from appropriate parties under whose rights or authority access is otherwise
restricted.  The foregoing rights granted to SouthTrust shall not, whether or
not and regardless of the extent to which the same are exercised, affect the
representations and warranties made in this Agreement by LSB.

                 (b)      All information furnished by the parties hereto
pursuant to this Agreement shall be treated as the sole property of the party
providing such information until the consummation of the Merger contemplated
hereby and, if such transaction shall not occur, the party receiving the
information shall return to the party which furnished such information, all
documents or other materials containing, reflecting or referring to such
information, shall use its best efforts to keep confidential all such
information, and shall not directly or indirectly use such information for any
competitive or other commercial purposes.  The obligation to keep such
information confidential shall continue for two (2) years from the date the
proposed transactions are abandoned but shall not apply to (i) any information
which (A) the party receiving the information was already in possession of
prior to disclosure thereof by the party furnishing the information, (B) was
then available to the public, or (C) became available to the public through no
fault of the party receiving the information; or (ii) disclosures pursuant to a
legal requirement or in accordance with an order of a court of competent
jurisdiction or regulatory agency; provided that the party which is the subject
of any such legal requirement or order shall use its best efforts to give the
other party at least ten (10) business days prior notice thereof.  Each party
hereto acknowledges and agrees that a breach of any of their respective
obligations under this Section 5.3 would cause the other irreparable harm for
which there is no adequate remedy



                                     A-16

at law, and that, accordingly, each is entitled to injunctive and other
equitable relief for the enforcement thereof in addition to damages or any
other relief available at law.

         Section 5.4      Approval of LSB Shareholders.  LSB will take all
steps necessary under applicable laws to call, give notice of, convene and hold
a meeting of its shareholders at such time as may be mutually agreed to by the
parties for the purpose of approving this Agreement and the transactions
contemplated hereby and for such other purposes consistent with the complete
performance of this Agreement as may be necessary or desirable.  Subject to
their fiduciary duties as advised in writing by counsel, the Board of Directors
of LSB will recommend to its shareholders the approval of this Agreement and
the transactions contemplated hereby and LSB will use its best efforts to
obtain the necessary approvals by its shareholders of this Agreement and the
transactions contemplated hereby.

         Section 5.5      No Other Bids.  LSB, acting through any director or
officer or other agent shall not now, nor shall it authorize or knowingly
permit any officer, director or employee of, or any investment banker,
attorney, accountant or other representative retained by LSB, to solicit or
encourage, including by way of furnishing information, any inquiries or the
making of any proposal which may reasonably be expected to lead to any takeover
proposal with respect to LSB. LSB shall promptly advise SouthTrust orally and
in writing of any such inquiries or proposals received by LSB after the date
hereof.  As used in this Section 5.5, "takeover proposal" shall mean any
proposal for a merger or other business combination involving LSB or for the
acquisition of a significant equity interest in LSB or for the acquisition of a
significant portion of the assets of LSB.

         Section 5.6      Notice of Deadlines.  LSB shall notify SouthTrust in
writing of any deadline to exercise an extension or termination of any material
lease, agreement or license (including specifically real property leases and
data processing agreements) to which LSB is a party, at least ten (10) days
prior to such deadline.

         Section 5.7      Affiliates.  At least thirty (30) days prior to the
Effective Time of the Merger, LSB shall deliver to SouthTrust a letter
identifying all persons who are, at the time this Agreement is submitted for
approval to the shareholders of LSB, "affiliates" of LSB for purposes of the
Securities Act of 1933.  In addition, LSB shall use its reasonable efforts to
cause each person who is a shareholder of LSB to deliver to SouthTrust not
later than thirty (30) days prior to the Effective Time of the Merger, a
written agreement, providing that such person will not sell, pledge, transfer,
or otherwise dispose of the LSB Shares held by such person, except as
contemplated by such agreement or by this Agreement, and will not sell, pledge,
transfer, or otherwise dispose of the SouthTrust Shares to be received by such
person upon consummation of the Merger except in compliance with applicable
provisions of the Securities Act of 1933, and the rules and regulations
thereunder and if such shareholder is an affiliate of LSB, until such time as
the financial results covering at least thirty (30) days of combined operations
of SouthTrust and LSB have been published within the meaning of Section 201.01
of the SEC's Codification of Financial Reporting Policies.  If the Merger will
qualify for pooling-of-interests accounting treatment, the SouthTrust Shares
issued to such affiliates of LSB in exchange for the LSB Shares shall not be
transferable until such time as the financial results covering at least thirty
(30) days of combined operations of SouthTrust and LSB have been published
within the meaning of Section 201.01 of the SEC's Codification of Financial
Reporting Policies regardless of whether each such person has provided the
written agreement referred to in this Section 5.7, 5.7.

         Section 6.2      Regulatory Matters.  (a)  Following the execution and
delivery of this Agreement, SouthTrust and LSB shall cause to be prepared and
filed all required applications and filings with the Regulatory Authorities
which are necessary or contemplated for the obtaining of the Consents of the
Regulatory Authorities or consummation of the Merger.  Such applications and
filings shall be in such form as may be prescribed by the respective government
agencies and shall contain such information as they may require.  The parties
hereto will cooperate with each other and use their best efforts to prepare and
execute all necessary documentation, to effect all necessary or contemplated
filings and to obtain all necessary or contemplated permits, consents,
approvals, rulings and authorizations of government agencies and third parties
which are necessary or contemplated to consummate the transactions contemplated
by this Agreement, including, without limitation, those required or
contemplated from the Regulatory Authorities, and the shareholders of LSB.

                 (b)      Each party hereto will furnish the other party with
all information concerning itself, its subsidiaries, directors, trustees,
officers, shareholders and depositors, as applicable, and such other matters as
may be necessary or advisable in connection with any statement or application
made by or on behalf of any such party to any governmental body in connection
with the transactions, applications or filings contemplated by this Agreement.
Upon request, the parties hereto will promptly furnish each other with copies

of the transactions contemplated hereby.

         Section 6.3      Other Matters.  (a) The parties acknowledge that
nothing in this Agreement shall be construed as constituting an employment
agreement between SouthTrust or any of its affiliates and any officer or
employee of LSB or obligation on the part of SouthTrust or any of its
affiliates to employ any such officers or employees.

         (b)     The parties agree that appropriate steps shall be taken to
terminate all employee benefit plans of LSB as of the Effective Time of the
Merger or as promptly as practicable thereafter.  Following the termination of
all such plans, SouthTrust agrees that the officers and employees of LSB who
the Surviving Corporation employs shall be eligible to participate in
SouthTrust's employee benefit plans, including welfare and fringe benefit plans
on the same basis as and subject to the same conditions as are applicable to
any newly-hired employee of SouthTrust; provided, however, that:

                          (i)     with respect to SouthTrust's group medical
                 insurance plan, SouthTrust shall credit each such employee for
                 eligible expenses incurred by such employee and his or her
                 dependents (if applicable) under LSB's group medical insurance
                 plan during the current calendar year for purposes of
                 satisfying the deductible provisions under SouthTrust's plan
                 for such current year, and SouthTrust shall waive all waiting
                 periods under said plans for pre-existing conditions; and

                          (ii)    credit for each such employee's past service
                 with LSB prior to the Effective Time of the Merger ("Past
                 Service Credit") shall be given by SouthTrust to employees for
                 purposes of:

                                  (1)      determining vacation and sick leave
                          benefits and accruals, in accordance with the
                          established policies of SouthTrust;

                                  (2)      establishing eligibility for
                          participation in and vesting under SouthTrust's
                          employee benefit plans (including welfare and fringe
                          benefit plans), and for purposes of determining the
                          scheduling of vacations and other determinations
                          which are made based on length of service,
                                     provided, however, notwithstanding
                          anything contained in this Agreement to the contrary,
                          Past Service Credit shall not be given to any such
                          employee for purposes of establishing eligibility in
                          the 1990 Discounted Stock Plan of SouthTrust.

         Section 6.4      Indemnification.  LSB agrees to indemnify, defend and
hold harmless SouthTrust and its subsidiaries, and each of their respective
present and former officers, directors, employees and agents, from and against
all losses, expenses, claims, damages or liabilities to which any of them may
become subject under applicable laws (including, but not limited to, the
Securities Act of 1933 or the Securities Exchange Act of 1934), 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 of material fact supplied by LSB and 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 to state therein a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made not misleading.

designated representatives to confer on a regular and frequent basis with LSB

         Section 6.6      Registration Statement.  SouthTrust shall cause the

the Effective Time of the Merger, shall in all material respects conform to the
requirements of the Securities Act of 1933 and the general rules and
regulations of the SEC under the Securities Act of 1933.  The Registration
Statement shall include the form of Proxy Statement for the meeting of LSB's
shareholders to be held for the purpose of having such shareholders vote upon
the approval of this Agreement.  LSB will furnish to SouthTrust the information
required to be included in the 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, on behalf of
ST-FL, shall reserve for issuance such number of SouthTrust Shares as shall be
necessary to pay the consideration contemplated in this Agreement.  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.

determination by SouthTrust that any fact, event or condition exists or has
occurred that, in the judgment of SouthTrust, (a) would have a material adverse

Condition of LSB or the consummation of the transactions contemplated by this
Agreement, (b) would be of such significance with respect to the business or
economic benefits expected to be obtained by SouthTrust pursuant to this
Agreement as to render inadvisable the consummation of the transactions
pursuant to this Agreement, (c) would be materially adverse to the interests of

exchange.

permit the succession by the Surviving Corporation to any obligation, right or
interest of LSB under any loan or credit agreement, note, mortgage, indenture,
lease, license, or other agreement or instrument, except those for which

SouthTrust sell or dispose of any significant amount of the assets of LSB 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 LSB or any banking or other subsidiary of SouthTrust, no
such term or condition imposed by any Regulatory Authority in connection with
the grant of any Consent by any Regulatory Authority shall be deemed to be a
material adverse requirement unless it materially differs from terms and
conditions customarily imposed by any such entity in connection with the
acquisition of banks under similar circumstances.

         Section 8.8      Matters Relating to Employment Agreements.  All
employment agreements, if any, between LSB and any executive or employee

         Section 11.3     Severability.  If any term, provision, covenant or

or against public or regulatory policy, the remainder of the terms, provisions,

force and effect and in no way shall be affected, impaired or invalidated, if,
but only if, pursuant to such remaining terms, provisions, covenants and

set forth in this Agreement as of the later of the date this Agreement was
executed or last amended.

         Section 11.4     Costs and Expenses.  Expenses incurred by LSB on the
one hand and SouthTrust on the other hand, in connection with or related to the

         Section 11.7     Governing Law.  This Agreement is made and shall be
governed by and construed in accordance with the laws of the State of Florida
without respect to its conflicts of laws principles.

         Section 11.8     Persons Bound; No Assignment.  This Agreement shall

                                 NATIONAL BANKS
                            CONSOLIDATION AND MERGER


Title 12 United States Code

Section  215A.   MERGER OF NATIONAL BANKS OR STATE BANKS INTO NATIONAL BANKS.

 . . .

         (b)     Dissenting shareholders

         If a merger shall be voted for at the called meetings by the necessary
majorities of the shareholders of each association or State bank participating
in the plan of merger, and thereafter the merger shall be approved by the
Comptroller, any shareholder of any association or State bank to be merged into
the receiving association who has voted against such merger at the meeting of
the association or bank of which he is a stockholder, or has given notice in
writing at or prior to such meeting to the presiding officer that he dissents
from the plan of merger, shall be entitled to receive the value of the shares
so held by him when such merger shall be approved by the Comptroller upon
written request made to the receiving association at any time before thirty
days after the date of consummation of the merger, accompanied by the surrender
of his stock certificates.

         (c)     Valuation of shares

         The value of the shares of any dissenting shareholder shall be
ascertained, as of the effective date of the merger, by an appraisal made by a
committee of three persons, composed of (1) one selected by the vote of the
holders of the majority of the stock, the owners of which are entitled to
payment in cash; (2) one selected by the directors of the receiving
association; and (3) one selected by the two so selected.  The valuation agreed
upon by any two of the three appraisers shall govern.  If the value so fixed
shall not be satisfactory to any dissenting shareholder who has requested
payment, that shareholder may, within five days after being notified of the
appraised value of his shares, appeal to the Comptroller, who shall cause a
reappraisal to be made which shall be final and binding as to the value of the
shares of the appellant.

         (d)     Application to shareholders of merging associations;
                 appraisal by Comptroller; expenses of receiving association;
                 sale and resale of shares; State appraisal and merger law

         If, within ninety days from the date of consummation of the merger,
for any reason one or more of the appraisers is not selected as herein
provided, or the appraisers fail to determine the value of such shares, the
Comptroller shall upon written request of any interested party cause an
appraisal to be made which shall be final and binding on all parties.  The
expenses of the Comptroller in making the reappraisal or the appraisal, as the
case may be, shall be paid by the receiving association.  The value of the
shares ascertained shall be promptly paid to the dissenting shareholders by the
receiving association.  The shares of stock of the receiving association which
would have been delivered to such dissenting shareholders had they not
requested payment shall be sold by the receiving association at an advertised
public auction, and the receiving association shall have the right to purchase
any of such shares at such public auction, if it is the highest bidder
therefor, for the purpose of reselling such shares within thirty days
thereafter to such person or persons and at such price not less than par as its
board of directors by resolution may determine.  If the shares are sold at
public auction at a price greater than the amount paid to the dissenting
shareholders, the excess in such sale price shall be paid to such dissenting
shareholders.  The appraisal of such shares of stock in any State bank shall be
determined in the manner prescribed by the law of the State in such cases,
rather than as provided in this section, if such provision is made in the State
law; and no such merger shall be in contravention of the law of the State under
which such bank is incorporated.  The provisions of this subsection shall apply
only to shareholders of (and stock owned by them in) a bank or association
being merged into the receiving association.
