     BancGroup.  BancGroup is a bank holding company within the meaning of the
Bank Holding Company Act of 1956, as amended (the "BHCA"). It was organized in
Delaware in 1974 and has operated under its current name and management since

existing subsidiary banks into its Alabama Bank, Colonial Bank, no later than
July 1, 1997. Colonial Mortgage Company, a subsidiary of the Colonial Bank in
Alabama, is a mortgage banking company which services approximately $10.6
billion in residential loans and which originates residential mortgages in 37
states through 6 regional offices. At December 31, 1996, BancGroup had
consolidated total assets of $4.9 billion and consolidated stockholders' equity
of $343.2 million. Since December 31, 1996, BancGroup has merged five banks into
BancGroup with aggregate assets of $896.9 million and aggregate stockholders'
equity of $66.6 million. These acquisitions are included in the pro forma
statements included herein. See "BUSINESS OF BANCGROUP."
 
     First Commerce.  First Commerce is a bank holding company under the BHCA,
having been incorporated on March 28, 1984. First Commerce owns 99.7% of the
outstanding shares of the Bank, which is headquartered in Winter Haven, Florida.
Currently, the Bank operates five offices located in Polk County, Florida. At
December 31, 1996, First Commerce had total consolidated assets of approximately
$105.9 million, total consolidated deposits of approximately $94.7 million and
total consolidated shareholders' equity of approximately $10.6 million. See
"BUSINESS OF FIRST COMMERCE."
 
TERMS OF THE MERGER
 
     The Agreement provides for the Merger of First Commerce with and into
BancGroup, with BancGroup to be the surviving corporation. Upon the date of
consummation of the Merger (the "Effective Date"), each outstanding share of
First Commerce Common Stock (except shares as to which dissenters' rights are
perfected) will be converted by operation of law and without any action by any
holder thereof into .4326 of a
                                        1
<PAGE>   9
 
share of BancGroup Common Stock (the "Merger Consideration"), provided that the
Market Value for BancGroup Common Stock is not less than $19.35 and not greater
than $25.16. If the Market Value is less than $19.35, then each share of First
Commerce Common Stock will be converted into the number of shares of BancGroup
Common Stock equal to $8.37 divided by the Market Value. If the Market Value is
greater than $25.16, then each share of First Commerce Common Stock will be
converted into the number of shares of BancGroup Common Stock equal to $10.88
divided by the Market Value. The "Market Value" will represent the per share
market value of the BancGroup Common Stock at the Effective Date and will be
determined by calculating the average of the closing prices of the BancGroup
Common Stock as reported by the NYSE on each of the 10 trading days ending on
the trading day five calendar days immediately preceding the Effective Date. The
appropriate ratio that is used to calculate the Merger Consideration based upon
the Market Value as set forth above is referred to as the "Exchange Ratio." If
BancGroup publicly announces prior to the Effective Date that it has entered
into an agreement pursuant to which BancGroup will be acquired through a merger,
sale of assets of BancGroup or tender offer or exchange offer for BancGroup
Common Stock (or otherwise), then the Exchange Ratio will be determined by
disregarding whether the Market Value is greater than $25.16. Any merger in
which BancGroup is the surviving corporation that does not involve a change of
control of BancGroup will be excluded from the preceding sentence. For this
purpose a "change of control" means the acquisition of beneficial ownership of
the BancGroup Common Stock by any person or group (as that term is defined under
section 13(d) of the Exchange Act) of more than 50 percent of the outstanding
shares of such stock.
 
     No fractional shares of BancGroup Common Stock will be issued in connection
with the Merger. To the extent that a fractional interest arises as a result of
the BancGroup Common Stock issuable in the Merger, cash will be paid in lieu
thereof based upon the Market Value.
 
     As of the date of this Prospectus, First Commerce had granted options and
warrants (collectively, the "First Commerce Options") which entitle the holders
thereof to acquire up to 321,215 shares of First Commerce Common Stock. On the
Effective Date, BancGroup will assume all First Commerce Options outstanding,
and each such option will represent the right to acquire BancGroup Common Stock
on substantially the same terms applicable to the First Commerce Options. The
number of shares of BancGroup Common Stock to be issued pursuant to such options
will equal the number of shares of First Commerce Common Stock subject to such
First Commerce Options multiplied by the Exchange Ratio, provided that no
fractions of shares of BancGroup Common Stock will be issued. The number of
shares of BancGroup Common Stock to be issued upon the exercise of First
Commerce Options, if a fractional share exists, will equal the number of whole
shares obtained by rounding to the nearest whole number, giving account to such
fraction, or by paying for such fraction in cash. The exercise price for the
acquisition of BancGroup Common Stock will be the exercise price for each share
of First Commerce Common Stock subject to such options divided by the Exchange
Ratio, adjusted appropriately for any rounding to whole shares that may be
required. As an alternative, holders of First Commerce Options may elect by
giving written notice to First Commerce before the Effective Date to be paid in
cash the difference between the exercise price for such options and the value of
such option determined at the Effective Date based upon the Exchange Ratio.
 
     First Commerce shareholders will be given notice of the consummation of the
Merger promptly after the Effective Date of the Merger. Certificates for the
shares of BancGroup Common Stock issued will not be distributed or dividends
paid on such shares until shareholders surrender their certificates representing
their shares of First Commerce Common Stock.

of First Commerce Common Stock Certificates," and "Treatment of First Commerce
Options."

RECOMMENDATION OF FIRST COMMERCE'S BOARD OF DIRECTORS
 
     The Board of Directors of First Commerce has unanimously approved the
Agreement. THE BOARD OF DIRECTORS OF FIRST COMMERCE BELIEVES THAT THE MERGER IS
FAIR TO, AND IN THE BEST INTERESTS OF, THE SHAREHOLDERS OF FIRST COMMERCE, AND
RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF THE AGREEMENT. For a
discussion of the factors considered by the Board of Directors in reaching its
conclusions, see "THE MERGER -- Background of the Merger" and "-- First
Commerce's Board of Directors' Reasons for Approving the Merger."
 
OPINION OF FINANCIAL ADVISOR
 
     First Commerce has received an opinion from Austin Associates, Inc. that
the terms of the Agreement are fair, from a financial point of view, to the
shareholders of First Commerce. The full text of Austin Associates, Inc.'s
opinion, which describes the procedures followed, assumptions made, limitations
on the review taken, and other matters in connection with rendering such
opinion, is set forth as Appendix B to this Prospectus and should be read in its
entirety by First Commerce shareholders. For additional information regarding
Austin Associates, Inc.'s opinion, see "THE MERGER -- Opinion of Financial
Advisor."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain of the directors and executive officers of First Commerce hold
First Commerce Options which entitle them to purchase, in the aggregate, up to
292,220 shares of First Commerce Common Stock. Under the terms of the Agreement,
any First Commerce Options which are not exercised prior to the Effective Date
will be assumed by BancGroup. See "THE MERGER -- Conversion of First Commerce
Common Stock" and "Treatment of First Commerce Options."
 
     BancGroup has agreed that, upon consummation of the Merger, the existing
employment agreement of Robert W. Stickler, Jr., Vice Chairman, President and
Chief Executive Officer of First Commerce, will remain in effect until
terminated in accordance with the provisions of the agreement. Also the Bank has
salary continuation agreements with Mr. Stickler and J. Jeffrey Seale, Vice
President and Controller of First Commerce, which will remain in effect after
the consummation of the Merger. See "THE MERGER -- Interests of Certain Persons
in the Merger."
 
     On the Effective Date, and subject to the existing agreement referenced
above, all employees of First Commerce will, at BancGroup's option, either
become employees of BancGroup or its subsidiaries or be entitled to severance
benefits in accordance with Colonial Bank's severance policy as of the date of
the Agreement. All employees of First Commerce who become employees of BancGroup
or its subsidiaries on the Effective Date will be entitled, to the extent
permitted by applicable law, to participate in all benefit plans of BancGroup to
the same extent as BancGroup's employees.
 
     Under the Agreement, BancGroup has agreed to indemnify the directors and
executive officers of First Commerce against certain claims and liabilities
arising out of or pertaining to matters existing or occurring at or prior to the
Effective Date, to the extent that First Commerce would have been permitted
under Florida law, or under its Articles of Incorporation or Bylaws, to
indemnify such persons.
 
     Except as indicated above, none of the directors or executive officers of
First Commerce, and no associate of any such person, has any substantial direct
or indirect interest in the Merger, other than an interest arising from the
ownership of First Commerce Common Stock.
 
     See "THE MERGER -- Interests of Certain Persons in the Merger."
 
VOTE REQUIRED
 
     Under Florida law, the Agreement must be approved by the affirmative vote
of the holders of at least a majority of the outstanding shares of First
Commerce Common Stock. Each share of First Commerce Common Stock is entitled to
one vote on the Agreement. Approval of the Agreement and the Merger by
                                        3
<PAGE>   11
 
BancGroup stockholders is not required under Delaware, Florida or other
applicable law, or the rules of the NYSE on which the BancGroup Common Stock is
listed. See "THE SPECIAL MEETING."
 
     Only holders of record of First Commerce Common Stock at the close of
business on the Record Date are entitled to notice of and to vote at the Special
Meeting. As of such date,             shares of First Commerce Common Stock were
issued and outstanding. As of the Record Date, the directors and executive
officers of First Commerce and the Bank held approximately      % of the
outstanding shares of First Commerce Common Stock. As of the same date, the
directors, executive officers and affiliates of BancGroup held no shares of
First Commerce Common Stock. See "THE SPECIAL MEETING."
 
     The directors of First Commerce own           shares of First Commerce
Common Stock representing approximately      % of the outstanding shares and
have agreed with BancGroup to vote their shares in favor of the Agreement. See
"THE SPECIAL MEETING." As of March 1, 1997, Directors and executive officers of
BancGroup beneficially owned in the aggregate 4,454,136 shares of BancGroup
Common Stock representing approximately 10.98% of BancGroup's outstanding
shares.
 
     Proxies should be returned to First Commerce in the envelope enclosed
herewith. Shareholders of First Commerce submitting proxies may revoke their
proxies by (i) giving notice of such revocation in writing to the Secretary of
First Commerce at or prior to the Special Meeting, (ii) by executing and
delivering a proxy bearing a later date to the Secretary of First Commerce at or
prior to the Special Meeting, or (iii) by attending the Special Meeting and
voting in person. Because approval of the Agreement requires the approval of at
least a majority of the outstanding shares of First Commerce Common Stock,
failure to submit a proxy or failure to vote in person at the Special Meeting
will have the same effect as a negative vote. See "THE SPECIAL
MEETING -- Solicitation, Voting and Revocation of Proxies."
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
     Holders of First Commerce Common Stock as of the Record Date are entitled
to dissenters' rights of appraisal pursuant to Sections 607.1301, 607.1302 and
607.1320 of the FBCA. The FBCA, as explained more fully in "THE MERGER -- Rights
of Dissenting Shareholders" permits a shareholder to dissent from the Merger and
obtain payment for the fair value of his shares. Such "fair value" may be
determined in a judicial proceeding, the result of which cannot be predicted.
Shareholders wishing to exercise dissenters' rights must follow properly all
requirements for the exercise of such rights as set forth in Sections 607.1301,
607.1302 and 607.1320 of the FBCA, a copy of which is attached as Appendix C to
this Prospectus. See "THE MERGER -- Rights of Dissenting Shareholders." Any
shareholder who properly exercises dissenters' rights and receives cash for his
or her shares will encounter income tax treatment different than the treatment
for shareholders who do not exercise dissenters' rights. See "THE
MERGER -- Rights of Dissenting Shareholders."
 
CONDITIONS TO THE MERGER
 
     The parties' obligation to consummate the Merger is subject to the
satisfaction (or waiver, to the extent permitted by law) of various conditions
set forth in the Agreement.
 
     The mutual obligations of the parties to consummate the Merger are subject
to the following conditions, among others: (i) the approval of the Agreement by
the holders of at least a majority of the outstanding shares of First Commerce
Common Stock; (ii) the approval of the Merger by The Board of Governors of the
Federal Reserve System (the "Federal Reserve") and the approval of the merger of
the Bank with Colonial Bank (the "Bank Merger") by the Alabama Banking
Department (the "Alabama Department") and the Federal Reserve; (iii) the absence
of any pending or threatened litigation which seeks to restrain or prohibit the
Merger; (iv) the consummation of the Merger on or before November 30, 1997; and
(v) receipt of opinions of counsel as to certain matters, including tax matters.
 
     The obligation of First Commerce to consummate the Merger is further
subject to several conditions, including: (i) the absence of any material
adverse changes in the financial condition or affairs of BancGroup;
                                        4
<PAGE>   12
 
and (ii) the shares of BancGroup Common Stock to be issued under the Agreement
shall have been approved for listing on the NYSE.
 
     The obligations of BancGroup to consummate the Merger are subject to
various conditions, including: (i) the absence of any material adverse change in
the financial condition or affairs of First Commerce; and (ii) the holders of
not more than 15% of the outstanding shares of First Commerce Common Stock shall
have exercised dissenters' rights with respect to their shares.
 
     Applications for appropriate regulatory approvals by the Federal Reserve
and the Alabama Department were filed with such agencies on April 21, 1997. The
regulatory approval process is expected to take approximately two months from
that date, and it is anticipated that the Merger will be consummated on or about
July 1, 1997.
 
     See "THE MERGER -- Conditions to Consummation of the Merger" and
"Regulatory Approvals."
 
AMENDMENT OR TERMINATION OF AGREEMENT
 
     The Boards of Directors of BancGroup and First Commerce may agree to amend
or terminate the Agreement at any time prior to the Effective Date. However, the
Board of Directors of First Commerce may not amend the Agreement which would
alter the Merger Consideration or which, in the opinion of the Board of
Directors of First Commerce, would adversely affect the rights of the
shareholders of First Commerce, unless such amendments are approved by the
holders of a majority of the outstanding First Commerce Common Stock. Such
amendments may require the filing of an amendment of the Registration Statement,
of which this Prospectus forms a part, with the Commission. See "THE
MERGER -- Amendment or Termination."
 
COMPARISON OF SHAREHOLDER RIGHTS
 
     The rights of the holders of the First Commerce Common Stock may be
different from the rights of the holders of the BancGroup Common Stock. A
discussion of these rights and a comparison thereof is set forth at "COMPARATIVE
RIGHTS OF STOCKHOLDERS."
 
FEDERAL INCOME TAX CONSEQUENCES
 
     No ruling with respect to the federal income tax consequences of the Merger
to First Commerce's shareholders will be requested from the Internal Revenue
Service (the "IRS"). First Commerce has received an opinion from Coopers &
Lybrand L.L.P., that, among other things, a shareholder of First Commerce who
exchanges shares of First Commerce Common Stock for BancGroup Common Stock will
not recognize gain except that, shareholders of First Commerce will recognize
gain to the extent such shareholders receive cash in lieu of fractional shares
of BancGroup Common Stock. Shareholders who receive cash for their shares of
First Commerce Common Stock upon perfection of dissenters' rights also, will
realize gain or loss for federal income tax purposes with respect to such
shares. See "APPROVAL OF THE MERGER -- Certain Federal Income Tax Consequences."
First Commerce shareholders are urged to consult their own tax advisors as to
the specific tax consequences to them of the Merger.
 
ACCOUNTING TREATMENT
 
     The acquisition of First Commerce will be treated as a "purchase"
transaction by BancGroup for accounting purposes. See "THE MERGER -- Accounting
Treatment."

CERTAIN LEGAL RESTRICTIONS ON ACQUISITIONS OF CONTROL
 
     Certain restrictions under Delaware law prevent a person who beneficially
owns 15% or more of the BancGroup Common Stock from engaging in a "business
combination" with BancGroup unless certain conditions are satisfied. Also, the
Change in Bank Control Act of 1978 prohibits a person from acquiring "control"
of BancGroup unless certain notice provisions with the Federal Reserve Board
have been satisfied.
 
     BancGroup's Restated Certificate of Incorporation and bylaws also contain
provisions which may deter or prevent a takeover of BancGroup that is not
supported by BancGroup's Board of Directors. These provisions include: (1) a
classified board of directors, (2) supermajority voting requirements for certain
"business combinations" that exceed the provisions of Delaware law described
above, (3) flexibility for the board to consider non-economic and other factors
in evaluating a "business combination," (4) inability of stockholders to call
special meetings and act by written consent, and (5) certain advance notice
provisions for the conduct of business at stockholder meetings.

(a) Pro forma equivalent per share amounts are calculated by multiplying the pro
    forma combined total income per share and the pro forma combined total book
    value per share of BancGroup by the conversion ratio so that the per share
    amounts are equated to the respective values for one share of First
    Commerce. For the purposes of these pro forma equivalent per share amounts,
    a .4326 BancGroup common stock share conversion ratio is utilized. The ratio
    is fixed under the Agreement provided the Market Value stays within a set
    range. See "THE MERGER -- Conversion of First Commerce Common Stock."
(b) Pro forma equivalent dividends per share are shown at BancGroup's Common
    Stock dividend per share rate multiplied by the .4326 conversion ratio per
    share of First Commerce common stock (see note (a)). BancGroup presently
    contemplates that dividends will be declared in the future. However, the
    payment of cash dividends is subject to BancGroup's actual results of
    operations as well as certain other internal and external factors.
    Accordingly, there is no assurance that cash dividends will either be
    declared and paid in the future, or, if declared and paid, that such
    dividends will approximate the pro forma amounts indicated.

                              THE SPECIAL MEETING
 
GENERAL
 
     This Prospectus is being furnished to the shareholders of First Commerce in
connection with the solicitation of proxies by the Board of Directors of First
Commerce for use at the Special Meeting. The purpose of the Special Meeting is
to consider and vote upon the Agreement which provides for the proposed Merger
of First Commerce with and into BancGroup. BancGroup will be the surviving
corporation in the Merger.
 
     This Prospectus is also furnished by BancGroup in connection with the offer
of shares of BancGroup Common Stock to be issued in the Merger. No vote of
BancGroup stockholders is required to approve the Merger.
 
     THE BOARD OF DIRECTORS OF FIRST COMMERCE BELIEVES THAT THE MERGER IS IN THE
BEST INTERESTS OF FIRST COMMERCE AND ITS SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS
THAT SHAREHOLDERS VOTE "FOR" THE AGREEMENT (ITEM 1 ON THE PROXY CARD).
 
RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED FOR THE MERGER
 
     The Board of Directors of First Commerce has fixed the close of business on
            , 1997, as the Record Date for determination of shareholders
entitled to vote at the Special Meeting. There were        record holders of
First Commerce Common Stock and           shares of First Commerce Common Stock
outstanding, each entitled to one vote per share, as of the Record Date. First
Commerce is obligated to issue an additional 321,215 shares of First Commerce
Common Stock upon the exercise of outstanding First Commerce Options.
 
     The presence at the Special Meeting, in person or by proxy, of the holders
of a majority of the outstanding shares of First Commerce Common Stock on the
Record Date is necessary to constitute a quorum for the transaction of business
at the Special Meeting. In the absence of a quorum, the Special Meeting may be
postponed from time to time until First Commerce shareholders holding the
requisite amount of shares of First Commerce Common Stock are represented in
person or by proxy. If a quorum is present, the affirmative vote of the holders
of at least a majority of the outstanding shares of First Commerce Common Stock,
whether or not present or represented at the Special Meeting, is required to
approve the Agreement. Broker nonvotes and abstentions will not be counted as
votes cast "FOR" or "AGAINST" the proposal to approve the Agreement, and, as a
result, such non-votes will have the same effect as votes cast "AGAINST" the
Agreement. Each holder of record of shares of First Commerce Common Stock is
entitled to cast, for each share registered in his or her name, one vote on the
Agreement as well as on each other matter presented to a vote of shareholders at
the Special Meeting.
 
     As of the Record Date, directors of First Commerce owned           shares
of First Commerce Common Stock representing approximately      % of the
outstanding shares. These individuals have agreed with BancGroup to vote the
shares owned by them in favor of the Merger.
 
     If the Agreement is approved at the Special Meeting, First Commerce is
expected to merge with and into BancGroup promptly after the other conditions to
the Agreement are satisfied. See "THE MERGER -- Conditions of Consummation of
the Merger."
 
     THE BOARD OF DIRECTORS OF FIRST COMMERCE URGES THE SHAREHOLDERS OF FIRST
COMMERCE TO EXECUTE AND RETURN THE ENCLOSED PROXY CARD AS SOON AS POSSIBLE AND
UNANIMOUSLY RECOMMENDS THAT THE SHARES REPRESENTED BY THE PROXY BE VOTED IN
FAVOR OF THE AGREEMENT.
 
SOLICITATION, VOTING AND REVOCATION OF PROXIES
 
     In addition to soliciting proxies by mail, directors, officers and other
employees of First Commerce, without receiving special compensation therefor,
may solicit proxies from First Commerce's shareholders by
 
                                       10
<PAGE>   18
 
telephone, by telegram or in person. Arrangements will also be made with
brokerage firms and other custodians, nominees and fiduciaries, if any, to
forward solicitation materials to any beneficial owners of shares of First
Commerce Common Stock.
 
     First Commerce will bear the cost of assembling and mailing this Prospectus
and other materials furnished to shareholders of First Commerce. It will also
pay all other expenses of solicitation, including the expenses of brokers,
custodians, nominees, and other fiduciaries who, at the request of First
Commerce, mail material to or otherwise communicate with beneficial owners of
the shares held by them. BancGroup will pay all expenses incident to the
registration of the BancGroup Common Stock to be issued in connection with the
Merger.
 
     Shares of First Commerce Common Stock represented by a proxy properly
signed and received at or prior to the Special Meeting, unless properly revoked,
will be voted in accordance with the instructions on the proxy. IF A PROXY IS
SIGNED AND RETURNED WITHOUT ANY VOTING INSTRUCTIONS, SHARES OF FIRST COMMERCE
COMMON STOCK REPRESENTED BY THE PROXY WILL BE VOTED "FOR" THE PROPOSAL TO
APPROVE THE AGREEMENT AND IN ACCORDANCE WITH THE DETERMINATION OF THE MAJORITY
OF THE BOARD OF DIRECTORS OF FIRST COMMERCE AS TO ANY OTHER MATTER WHICH MAY
PROPERLY COME BEFORE THE SPECIAL MEETING, INCLUDING ANY ADJOURNMENT OR
POSTPONEMENT THEREOF. A shareholder may revoke any proxy given pursuant to this
solicitation by: (i) delivering to the Secretary of First Commerce, prior to or
at the Special Meeting, a written notice revoking the proxy; (ii) delivering to
the Secretary of First Commerce, at or prior to the Special Meeting, a duly
executed proxy relating to the same shares and bearing a later date; or (iii)
voting in person at the Special Meeting. All written notices of revocation and
other communications with respect to the revocation of First Commerce's proxies
should be addressed to:
                            First Commerce Banks of Florida, Inc.

                            Winter Haven, Florida 33880
                            Attention: J. Jeffrey Seale, Secretary
 
     Attendance at the Special Meeting will not, in and of itself, constitute a
revocation of a proxy.
 
     Proxies marked as abstentions and shares held in street name which have
been designated by brokers on proxy cards as not voted will not be counted as
votes cast. Such proxies will, however, be counted for purposes of determining
whether a quorum is present at the Special Meeting.
 
     The Board of Directors of First Commerce is not aware of any business to be
acted upon at the Special Meeting other than consideration of the Merger
described herein. If, however, other matters are properly brought before the
Special Meeting, or any adjournments or postponements thereof, the persons
appointed as proxies will have the discretion to vote or act on such matters
according to their best judgment. Proxies voted in favor of the Merger, or
proxies as to which no voting instructions are given, will be voted to adjourn
the Special Meeting, if necessary, in order to solicit additional proxies in
favor of the Merger. Proxies voted against the Merger and abstentions will not
be voted for an adjournment. See "ADJOURNMENT OF THE SPECIAL MEETING."
 
EFFECT OF MERGER ON OUTSTANDING BANCGROUP COMMON STOCK
 
     Assuming that no dissenters' rights of appraisal are exercised in the
Merger, no First Commerce Options are exercised prior to the Merger, and a
Market Value not less than $19.35 and no more than $25.16, BancGroup would issue
685,990 shares of BancGroup Common Stock to the shareholders of First Commerce
pursuant to the Merger based upon the Exchange Ratio of .4326. Based on those
assumptions, the 685,990 shares of BancGroup Common Stock would represent
approximately 1.7% of the total number of shares of BancGroup Common Stock
outstanding following the Merger, not counting any additional shares BancGroup
may issue, including shares to be issued pursuant to other pending acquisitions.
BancGroup anticipates that the shares of BancGroup Common Stock to be issued in
the Merger will come from shares repurchased by BancGroup in the open market.

     THE FOLLOWING SETS FORTH A SUMMARY OF THE MATERIAL PROVISIONS OF THE
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY. THE DESCRIPTION DOES NOT
PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
AGREEMENT ATTACHED HERETO AS APPENDIX A AND CERTAIN PROVISIONS OF FLORIDA LAW
RELATING TO THE RIGHTS OF DISSENTING SHAREHOLDERS, A COPY OF WHICH PROVISIONS
ARE ATTACHED HERETO AS APPENDIX C. ALL FIRST COMMERCE SHAREHOLDERS ARE URGED TO
READ THE AGREEMENT AND THE APPENDICES IN THEIR ENTIRETY.
 
GENERAL
 
     The Agreement provides that, subject to shareholder approval, receipt of
necessary regulatory approval and certain other conditions described below at
"Conditions to Consummation of the Merger," First Commerce will merge with and
into BancGroup. Upon completion of the Merger, the corporate existence of First
Commerce will cease, and BancGroup will succeed to the business formerly
conducted by First Commerce.
 
BACKGROUND OF THE MERGER
 
     On January 3, 1996, First Commerce entered into a Plan of Merger and Merger
Agreement with First Mercantile National Bank ("First Mercantile"), Longwood,
Florida, whereby First Mercantile would become a wholly-owned subsidiary of
First Commerce. At the same time, First Commerce entered into a similar
agreement with Prime Bank of Central Florida ("Prime Bank"), headquartered in
Titusville, Florida. These transactions intended to bring the First Commerce,
First Mercantile and Prime Bank organizations together on a "combination of
equals" basis. The First Commerce agreements with First Mercantile and Prime
Bank were terminated by mutual consent effective August 1, 1996, as a result of
certain issues, including an increase in First Commerce's non-performing assets
and a decrease in its earnings.
 
     Following the termination of the agreements between First Commerce and
First Mercantile and Prime Bank, the Board of Directors of First Commerce
engaged T. Stephen Johnson & Associates, Inc. ("TSJA"), an investment banking
firm which specializes in the securities of southeastern United States'
financial institutions, to assist First Commerce in the assessment of its
strategic position. At a meeting of the Boards of Directors of First Commerce
and the Bank held on November 18, 1996, TSJA presented an analysis of First
Commerce's financial position and results of operations. TSJA also discussed
certain financial and operating criteria that First Commerce needed to
accomplish, and the time period within which such results might be achievable,
in order for First Commerce to realize earnings and performance ratios
comparable to peer financial institutions. Among other issues discussed during
the presentation was the assessment that it may take First Commerce
approximately three years to report earnings in the range of comparable
financial institutions and that there was no assurance that the prevailing
multiples being paid for independent community banks would continue or be
realized by First Commerce shareholders at that time.
 
     After the conclusion of the planning session, the First Commerce directors
requested that TSJA explore the market among regional financial institutions for
a potential acquisition of First Commerce, without committing to any sale of
First Commerce at that time. The Board of Directors was interested in
determining if there were opportunities out there for a possible sale of First
Commerce and the range of pricing that First Commerce might realize in such a
transaction. First Commerce and TSJA prepared a confidential information package
setting forth certain financial, budget, branch, loan, employment, option and
warrant, and shareholder ownership information and other data. TSJA then
solicited indications of interest from a group of regional financial
institutions selected by First Commerce.
 
     On December 19, 1996, TSJA called five financial institutions to solicit
their interest in acquiring First Commerce. On December 23, 1996, confidential
information regarding First Commerce was sent to the four financial institutions
requesting the information. On January 7, 1997, TSJA advised each of the
financial institutions of a January 17, 1997 date for the submission of
proposals regarding an acquisition of First Commerce. One of the four financial
institutions declined to issue a proposal. On January 8, 1997, TSJA contacted
two additional regional financial institutions to see if they had any interest
in acquiring First Commerce. These two institutions declined to receive
confidential information regarding First Commerce. On
 
                                       12
<PAGE>   20
 
January 9, 1997, BancGroup and another financial institution requested
additional information on First Commerce. On January 16, 1997, the audited
financial statements of First Commerce for 1996 were provided to the three
remaining interested financial institutions, two of which declined to submit any
proposal for the acquisition of First Commerce. On January 17, 1997 BancGroup
delivered a proposal for the acquisition of First Commerce, subject to certain
conditions, including a due diligence review of First Commerce by BancGroup.
 
     At a special meeting of the First Commerce Board of Directors held on
January 27, 1997, the directors reviewed the BancGroup proposal and authorized
First Commerce executives to continue their discussions with BancGroup. During
the first two weeks of February, 1997, BancGroup conducted a due diligence
review of First Commerce. At a special meeting of the First Commerce Board of
Directors held on February 12, 1997, representatives of BancGroup met with First
Commerce directors. During the meeting, the BancGroup representatives presented
financial and other information regarding BancGroup. The BancGroup
representatives and First Commerce directors also reached an agreement that an
acquisition of First Commerce by BancGroup would provide for an exchange ratio
of .4326 shares of BancGroup Common Stock for each share of First Commerce
Common Stock. On February 13, 1997, BancGroup and First Commerce entered into a
letter of intent providing for BancGroup's acquisition of First Commerce in
accordance with the foregoing exchange ratio.
 
     From February 14, 1997 through March 23, 1997, BancGroup and First Commerce
reviewed drafts, and negotiated the terms, of a definitive agreement. On March
10, 1997, First Commerce retained Austin Associates, Inc. ("AAI") to provide an
opinion to the First Commerce Board as to the fairness of the Merger, from a
financial point of view, to the shareholders of First Commerce. The Agreement
was reviewed and approved by the Board of Directors of First Commerce at a
meeting held on March 24, 1997. At this meeting, the directors reviewed the
terms of the Agreement and related issues. Also at the meeting, a representative
of AAI rendered an opinion that the terms of the Merger are fair, from a
financial point of view, to the shareholders of First Commerce. The First
Commerce Board then unanimously approved the Agreement and the transactions
contemplated thereby.
 
FIRST COMMERCE'S BOARD OF DIRECTORS' REASONS FOR APPROVING THE MERGER
 
     First Commerce's Board of Directors believes that the Merger is in the best
interests of First Commerce and its shareholders. The Board of Directors of
First Commerce considered a number of factors in deciding to approve and
recommend the terms of the Agreement to First Commerce shareholders, including
the terms of the proposed transaction; the financial condition, results of
operations, and future prospects of First Commerce; the value of the
consideration to be received by First Commerce shareholders relative to the book
value and earnings per share of First Commerce Common Stock; the competitive and
regulatory environment for financial institutions generally; the fact that the
Merger will enable First Commerce shareholders to exchange their shares of First
Commerce Common Stock for shares of common stock of a larger and more
diversified entity, the stock of which is more widely held and more actively
traded; that the Merger will enable First Commerce shareholders to hold stock in
a financial institution that has historically paid cash dividends to its
shareholders (as compared to First Commerce, which has not paid any cash
dividends to its shareholders); the likelihood of receiving the requisite
regulatory approvals; that it is expected that the Merger will be a tax-free
transaction (except in respect of cash received for First Commerce Common Stock)
for federal income tax purposes; and other information. The Board of Directors
also took into account an opinion received from Austin Associates, Inc. that the
terms of the Agreement are fair, from a financial point of view, to the
shareholders of First Commerce. See "-- Opinion of Financial Advisor." The
foregoing discussion of the information and factors considered by the Board of
Directors is not intended to be exhaustive of the factors considered by the
Board of Directors. The First Commerce Board of Directors did not assign any
relative or specific weights to the foregoing factors, and individual directors
may have given different weights to different factors.

OPINION OF FINANCIAL ADVISOR
 
     Austin Associates, Inc. ("AAI") is a recognized investment banking firm
regularly engaged in the valuation of financial institutions and their
securities in connection with mergers and acquisitions and other purposes. First
Commerce selected AAI to issue a fairness opinion in connection with the Merger
on the basis of its reputation and qualifications.
 
     AAI has rendered a separate written opinion to the board of directors of
First Commerce to the effect that the terms of the Agreement are fair, from a
financial point of view, to the shareholders of First Commerce as of the date of
the opinion. AAI based its opinion upon, among other things: (i) this
Prospectus; (ii) the audited financial statements of First Commerce and
BancGroup for the period 1992 through 1996; (iii) the reported prices and stock
trading activity of First Commerce and BancGroup; (iv) publicly available
information regarding the performance of certain other companies whose business
activities were believed to be generally comparable to those of First Commerce
and BancGroup; (v) the financial terms, to the extent publicly available, of
certain comparable bank merger transactions; and (vi) such other analysis and
information deemed relevant.
 
     No limitations were imposed on the scope of AAI's investigation. The terms
of the Agreement, including the Exchange Ratio, were negotiated by First
Commerce and BancGroup, and their representatives, on an arm's-length basis. AAI
did not participate in the negotiation of the terms of the Agreement; however,
it did advise the Board of First Commerce during the negotiation of the Exchange
Ratio. A copy of the fairness opinion is attached as Appendix B to this
Prospectus and should be read in its entirety.
 
     In connection with rendering its opinion, AAI performed a variety of
financial analyses, which are summarized below. AAI believes its analyses must
be considered as a whole and that selecting portions of such analyses and the
factors considered therein, without considering all factors and analyses, could
create an incomplete view of the analyses and the process underlying AAI's
opinion. The preparation of a fairness opinion is a complex process involving
subjective judgments and is not necessarily susceptible to partial analyses or
summary description. In its analyses, AAI made numerous assumptions with respect
to industry performance, business and economic conditions, and other matters,
many of which are beyond the control of First Commerce and BancGroup. Any
estimates contained in AAI's analyses are not necessarily indicative of future
results or values, which may be significantly more or less favorable than the
estimates.
 
     Transaction Summary.  The terms of the Agreement provide for an Exchange
Ratio of 0.4326 shares of BancGroup Common Stock for each outstanding share of
First Commerce, provided that the Market Value (as defined in the Agreement) of
BancGroup is not less than $19.35 and not greater than $25.16 per share. This
corresponds to per share consideration for each First Commerce share of between
$8.37 and $10.88. If the Market Value of BancGroup is less than $19.35, the
Exchange Ratio shall be increased to provide for a minimum per share
consideration of $8.37 for each First Commerce share. If the Market Value of
BancGroup is greater than $25.16, the Exchange Ratio shall be decreased to
provide for a maximum per share consideration of $10.88 for each First Commerce
share. If BancGroup publicly announces prior to the Effective Date that it has
entered into an agreement pursuant to which it will be acquired, the Exchange
Ratio shall be determined by disregarding whether the Market Value is greater
than $25.16 per share. The Agreement further provides that BancGroup shall
assume all First Commerce options and warrants adjusted for the Exchange Ratio.
Based on 1,585,737 outstanding First Commerce common shares, and outstanding
options and warrants respecting the issuance of 321,215 shares of First Commerce
common stock, the aggregate consideration in the Merger ranges from a minimum
value of approximately $14.8 million to a maximum value of $19.6 million. Based
on the closing market price of BancGroup on March 31, 1997 of $23.00, the
transaction is valued at $17.8 million, which equals 167 percent of First
Commerce's December 31, 1996 book value.
 
     BancGroup Market Price and Financial Performance.  The closing market price
of BancGroup was $23.00 on March 31, 1997. BancGroup originally reported fully
diluted earnings per share ("EPS") of $1.60 for 1996, including a one-time
charge of $.07 per share for the SAIF special assessment. As of December 31,
1996, BancGroup originally reported a book value of $10.48 per share. Based on
the March 31 market price, BancGroup shares are valued at 14.4 times 1996 fully
diluted EPS and 219 percent of December 31, 1996
 
                                       14

book value. AAI compared BancGroup's stock trading multiples to banking
organizations headquartered in Alabama, Florida, Georgia, Louisiana,
Mississippi, North Carolina, South Carolina and Tennessee with assets ranging
from $1.5 billion to $25 billion (the "Peer Group"). As of March 31, 1997, the
median price-to-book multiple for the 21 organizations comprising the Peer Group
was 209% compared to BancGroup's multiple of 219%. The median price-to-earnings
multiple for the Peer Group was 14.9 compared to BancGroup's multiple of 14.4.
The median dividend yield for the Peer Group was 2.62 percent compared to
BancGroup's dividend yield of 2.61 percent.
 
     AAI also reviewed the originally reported financial performance of
BancGroup as compared to the Peer Group. The median return on average assets
("ROA") of the Peer Group for 1996 was 1.26% compared to BancGroup's ROA of
1.19%. The median return on average equity ("ROE") of the Peer Group for 1996
was 14.83% compared to BancGroup's ROE of 16.80%. For the period 1992 through
1996, the Peer Group recorded a five year median ROA of 1.16%, compared to
BancGroup's five year average ROA of 1.05%. During the 1992 to 1996 time period,
the Peer Group recorded a five year median ROE of 14.46%, compared to
BancGroup's five year average ROE of 16.65%. The leverage ratio for BancGroup as
of December 31, 1996 of 6.65% compared to the Peer Group median of 7.94%. During
1996, BancGroup recorded an efficiency ratio of 57.9 percent compared to the
Peer Group median of 59.6 percent.
 
     In addition to overall performance measures, AAI reviewed certain
originally reported asset quality measures. The ratio of nonperforming assets to
total assets for BancGroup was the highest of all Peer Group banks at 0.64%, and
compared to the Peer median of 0.30%. The loan loss reserve to total loan ratio
for BancGroup of 1.23% compared to a Peer median of 1.52%.
 
     Comparative Transactions.  AAI reviewed comparison prices in 27 sale of
control transactions in Florida for banks having assets ranging from $50 million
to $200 million since January 1, 1995. The median multiples for these
transactions were 206% of book value and 17.8 times earnings. AAI also screened
this Peer Group to determine the 25th percentile rankings for transaction
pricing and underlying performance measures. At the 25th percentile, the Peer
Group price-to-book multiple measured 163% and the price-to-earnings multiple
measured 15.0.
 
     AAI also reviewed the financial performance of First Commerce as compared
to the Peer Group. The 25th percentile ROA of the Peer Group for the year prior
to sale of 0.88% compared to First Commerce's 1996 ROA of 0.13%. The 25th
percentile ROE of the Peer Group for the year prior to sale was 8.92% compared
to First Commerce's 1996 ROE of 1.31%. For the five years preceding sale, the 15
Peer Group banks that sold during 1996 recorded a 25th percentile ROA of 0.59%,
compared to First Commerce's 1992-1996 five year average ROA of 0.61%. The Peer
Group banks that sold during 1996 recorded a preceding five year 25th percentile
ROE of 7.31%, compared to First Commerce's 1992-1996 five year average ROE of
7.62%.
 
     In addition to overall performance measures, AAI reviewed certain asset
quality measures. The ratio of nonperforming assets to total assets for First
Commerce of 2.57%, compared to the Peer Group 75th percentile of 1.33% (i.e. 75
percent of peer banks had lower ratios). The ratio of loan loss reserve to
nonperforming loans for First Commerce measured 53.8% compared to the Peer Group
25th percentile of 61.7%.
 
     Contribution Analysis.  AAI compared the pro forma ownership interest in
BancGroup that First Commerce shareholders would receive, in the aggregate, to
the contribution by First Commerce to the total assets, equity and net income of
the combined organization. Based on March 1, 1997 information, First Commerce
shareholders would own approximately 1.73% of BancGroup on a pro forma basis.
First Commerce's restated pro forma contribution of total assets would have
equaled 1.81%, the contribution of total equity would have equaled 2.65%, and
the contribution of 1996 net income would have equaled 0.29%.
 
     Based on First Commerce's relatively high loan loss provision and other
operating expenses during 1995 and 1996, AAI has recalculated First Commerce's
normalized earnings capacity for purposes of completing this Contribution
Analysis and the Summary Pro Forma Analysis presented in the following section.
Based on AAI's review of First Commerce's historical earnings trends, 1997
budget, year to date performance through February 1997, other internal reports
and discussions with management, AAI assumed a current normalized
 
                                       15
<PAGE>   23
 
earnings capacity for First Commerce at an annualized ROA of 1.00%. Based on
First Commerce's average asset level of $109.5 million during 1996, this
corresponds to an annualized earnings capacity of $1,095,000. Assuming this
level of earnings, First Commerce would have contributed 2.23% of the restated
pro forma combined earnings of BancGroup during 1996.
 
     Summary Pro Forma Analysis.  AAI also reviewed the pro forma effect of the
Merger to First Commerce's earnings per share and book value per share. First
Commerce recorded fully diluted earnings per share in 1996 of $0.08. Based on an
assumed $1,095,000 of normalized earnings capacity, First Commerce would have a
fully diluted earnings per share capacity of $0.65. First Commerce's book value
per share as of December 31, 1996 equaled $6.69. Giving effect to the Merger as
of December 31, 1996, including the effect of BancGroup's completed and proposed
business combinations, the equivalent First Commerce earnings per share would
have equaled $0.51, an increase of $0.43 over actual results. Book value per
share would have decreased to $4.49 per share, a decrease of $2.20 from actual
results.
 
     Discounted Cash Flow Analysis.  AAI performed a discounted cash flow
("DCF") analysis of the value of First Commerce as of December 31, 1996. A DCF
analysis is a forward looking projection based principally on estimated future
earnings capacity and asset growth. To provide a range of values, AAI selected
three separate growth scenarios and three separate ROA forecasts. DCF values
were determined based on asset growth scenarios of 5%, 10% and 15%. In addition,
AAI estimated ROA ratios for First Commerce for a five year time period (1997 to
2001). The three ROA scenarios consisted of: (1) a flat ROA of 1.00% in each
year; (2) an increasing ROA from 1.00%, to 1.05%, to 1.10%, to 1.15% and to
1.20% from 1997 to 2001; and (3) an increasing ROA from 1.00%, to 1.10%, to
1.20%, to 1.30% and to 1.40% from 1997 to 2001. Based on these assumptions, nine
separate DCF values for First Commerce were calculated. The DCF values for First
Commerce ranged from $11.7 million (5% growth, flat 1.00% ROA) to $18.5 million
(15% growth, increasing ROA from 1.00% to 1.40%).
 
     Dividends.  AAI reviewed the cash dividends to be received by First
Commerce shareholders as a result of the Merger. Based on an exchange ratio of
0.4326 BancGroup shares for each share of First Commerce, equivalent dividends
to First Commerce shareholders would have been $0.23 per share in 1996. No cash
dividends have been paid previously to First Commerce shareholders.
 
     The summary set forth above does not purport to be a complete description
of the analyses performed by AAI. Further, AAI did not conduct a physical
inspection of any of the properties or assets of First Commerce or BancGroup.
AAI has assumed and relied upon the accuracy and completeness of the financial
and other information provided to it or publicly available, has relied upon the
representations and warranties of First Commerce and BancGroup made pursuant to
the Agreement, and has not independently attempted to verify any of such
information. AAI has also assumed that the conditions to the Merger as set forth
in the Agreement would be satisfied and that the Merger would be consummated on
a timely basis in the manner contemplated by the Agreement. No limitations were
imposed by First Commerce or BancGroup on AAI as to the scope of its
investigation nor were any specific instructions given to AAI in connection with
its fairness opinion.
 
     For AAI's services as financial advisor, First Commerce will pay the firm a
fee of $17,500. In addition, First Commerce has agreed to reimburse AAI for
reasonable out-of-pocket expenses and indemnify AAI against certain liabilities,
including liabilities under the securities laws.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF FIRST COMMERCE
 
     The Board of Directors of First Commerce has determined that the Merger is
in the best interests of First Commerce and its shareholders. THE BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF FIRST COMMERCE VOTE IN
FAVOR OF THE APPROVAL AND ADOPTION OF THE MERGER AND THE AGREEMENT.
 
                                       16
<PAGE>   24
 
BANCGROUP'S REASONS FOR THE MERGER
 
     The Board of Directors of BancGroup has unanimously approved the Merger and
the Agreement. BancGroup has been seeking to expand its banking operations in
the state of Florida. BancGroup currently operates a commercial bank in the
Orlando, Ormond Beach and the Miami Beach areas, with acquisitions pending in
the Tampa and West Palm Beach areas. The Board of Directors of BancGroup
believes that the combination with First Commerce and the Bank is consistent
with that strategy.
 
     In approving the Merger and the Agreement, the Board of Directors of
BancGroup took into account: (i) the financial performance and condition of
First Commerce, including its strong capital and good asset quality; (ii)
similarities in the philosophies of BancGroup and First Commerce, including
First Commerce's commitment to delivering high quality personalized financial
services to its customers; and (iii) First Commerce's management's knowledge of
and experience in the Polk County, Florida market.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain directors and executive officers of the Bank hold First Commerce
Options which entitle them to purchase, in the aggregate, up to 292,220 shares
of First Commerce Common Stock. Under the terms of the Agreement, any First
Commerce Options which are not exercised prior to the Effective Date will be
assumed by BancGroup giving the holders of such options the right to acquire
shares of BancGroup Common Stock. As an alternative to assumption by BancGroup,
holders of First Commerce Options may elect by giving written notice to First
Commerce before the Effective Date to be paid in cash the difference between the
exercise price for such options and the value of such option determined at the
Effective Date based upon the Exchange Ratio. See "Conversion of First Commerce
Common Stock" and "Treatment of First Commerce Options."
 
     BancGroup has agreed that, upon consummation of the Merger, the existing
employment agreement of Robert W. Stickler, Jr., Vice Chairman, President and
Chief Executive Officer of First Commerce, will remain in effect until
terminated in accordance with the provisions of the agreement. Under the
agreement, Mr. Stickler currently receives an annual base salary of $140,000,
and is eligible for annual bonuses as determined by the Board of Directors. The
employment agreement provides for reimbursement of certain business related
expenses, and the maintenance by First Commerce and the Bank of officers' and
directors' insurance coverage. The employment agreement also provides that Mr.
Stickler will not work for any financial institution located within a radius of
50 miles of any office of the Bank for a two-year period following voluntary
termination of employment by Mr. Stickler or termination of employment for the
executive for "cause" (as defined in the employment agreement). Mr. Stickler has
also agreed in the employment agreement not to solicit Bank employees and
customers during the two-year period. The employment agreement provides for Mr.
Stickler to terminate his employment for "good reason" (as defined in the
agreement). The employment agreement terminates on August 31, 1998. If after a
change of control of First Commerce or the Bank and before August 31, 1998, Mr.
Stickler's employment is terminated, his duties are materially reduced, his base
salary is reduced, his employment is relocated more than 50 miles from the
Bank's main office, or his participation in any employee benefit plan is
materially reduced or adversely affected, and Mr. Stickler does not consent to
such change, then Mr. Stickler is entitled to receive promptly thereafter an
amount equal to two times the average base annual salary received by him during
the five-year period prior to such termination. The closing of the Merger will
constitute a change of control for purposes of Mr. Stickler's employment
agreement.
 
     The Bank also has entered into separate salary continuation agreements with
Mr. Stickler and J. Jeffrey Seale (Vice President and Controller of First
Commerce). The agreements require the Bank to pay $8,133 and $2,325 per month to
Messrs. Stickler and Seale, respectively, for 180 months following their
retirement or death. If the executive's employment is terminated by him
voluntarily or by the Bank with "just cause" (as defined in the agreements),
then the executive is entitled to receive his portion of the monthly payments in
accordance with a vesting schedule which provides for vesting at 40% after 1996
and 10% for each year thereafter. The executive is considered to be fully vested
if First Commerce or the Bank merges with another company and the executive is
terminated for any reason. The agreements do not affect the right of the
executive to participate in any other retirement plans or supplemental
compensation arrangements provided by
 
                                       17
<PAGE>   25
 
First Commerce or the Bank. To fund the obligations under the agreements, First
Commerce has purchased life insurance policies on the participants. For
additional information regarding the salary continuation agreements, see Note 14
to the Notes to First Commerce's Consolidated Financial Statements.
 
     On the Effective Date and subject to the agreements described above, all
employees of First Commerce (including its executive officers) will, at
BancGroup's option, either become employees of BancGroup or its subsidiaries or
be entitled to severance benefits in accordance with the severance policy of
Colonial Bank, as of the date of the Agreement. All employees of First Commerce
who become employees of BancGroup or its subsidiaries on the Effective Date will
be entitled, to the extent permitted by applicable law, to participate in all
benefit plans of BancGroup to the same extent as BancGroup's employees.
 
     Under the Agreement, BancGroup has agreed to indemnify the directors and
executive officers of First Commerce against certain claims and liabilities
arising out of or pertaining to matters existing or occurring at or prior to the
Effective Date, to the extent that First Commerce would have been permitted
under Florida law, or under its Articles of Incorporation or Bylaws, to
indemnify such persons.
 
     Except as described above, none of the directors or executive officers of
First Commerce, and no associate of any such person, has any substantial direct
or indirect interest in the Merger, other than an interest arising from the
ownership of First Commerce Common Stock.
 
CONVERSION OF FIRST COMMERCE COMMON STOCK
 
     On the Effective Date, each share of First Commerce Common Stock
outstanding and held by First Commerce's shareholders (except shares as to which
dissenters' rights are perfected) will be converted by operation of law and
without any action by any holder thereof into .4326 of a share of BancGroup
Common Stock subject to adjustment as determined below (the "Merger
Consideration") provided that the Market Value for BancGroup Common Stock is not
less than $19.35 and not greater than $25.16. If the Market Value is less than
$19.35, then each share of First Commerce Common Stock will be converted into
the number of shares of BancGroup Common Stock that will equal $8.37 divided by
the Market Value. If the Market Value is greater than $25.16, then each share of
First Commerce Common Stock will be converted into the number of shares of
BancGroup Common Stock that will equal $10.88 divided by the Market Value. The
Market Value will represent the per share market value of the BancGroup Common
Stock at the Effective Date and will be determined by calculating the average of
the closing prices of the Common Stock of BancGroup as reported by the NYSE on
each of the 10 consecutive trading days ending on the trading day five calendar
days immediately preceding the Effective Date.
 
     If BancGroup publicly announces prior to the Effective Date that it has
entered into an agreement pursuant to which BancGroup will be acquired through a
merger, sale of assets of BancGroup or tender offer or exchange offer for
BancGroup Common Stock (or otherwise), then the Exchange Ratio will be
determined by disregarding whether the Market Value is greater than $25.16. Any
merger in which BancGroup is the surviving corporation that does not involve a
change of control of BancGroup will be excluded from the preceding sentence. For
this purpose a "change of control" means the acquisition of beneficial ownership
of BancGroup Common Stock by any person or group (as that term is defined under
section 13(d) of the Exchange Act) of more than 50 percent of the outstanding
shares of such stock.
 
     No fractional shares of BancGroup Common Stock will be issued in the
Merger. Each shareholder of First Commerce having a fractional interest arising
upon the conversion of First Commerce Common Stock into BancGroup Common Stock
will, at the time of surrender of the certificates representing First Commerce
Common Stock, be paid by BancGroup an amount of cash equal to such fractional
interest multiplied the Market Value.
 
     As an example, assuming the Market Value of BancGroup Common Stock at the
Merger is no less than $19.35 and not greater than $25.16, then a shareholder of
First Commerce who owns 500 shares of First Commerce Common Stock would receive
216.3 shares of BancGroup Common Stock (.4326 multiplied by 500) with the .3 of
a share paid in cash based upon the Market Value. If the Market Value is greater
than
 
                                       18
<PAGE>   26
 
$25.16 or less than $19.35, the Exchange Ratio will be adjusted as described
above. The closing sales price on the NYSE of the BancGroup Common Stock on
April 14, 1997 was $22 7/8 per share.
 
     Shareholders are advised to obtain current market quotations for BancGroup
Common Stock. The market price of BancGroup Common Stock at the Effective Date,
or on the date on which certificates representing such shares are received by
First Commerce shareholders, may be higher or lower than the market price of
BancGroup Common Stock as of the Record Date or at the time of the Special
Meeting.
 
     The Agreement provides that if, prior to the Effective Date, BancGroup
Common Stock is changed into a different number of shares or a different class
of shares by reason of any recapitalization or reclassification, stock dividend,
combination, stock split, or reverse stock split of the BancGroup Common Stock,
an appropriate and proportionate adjustment will be made in the number of shares
of BancGroup Common Stock into which the First Commerce Common Stock will be
converted in the Merger.
 
     For a description of the assumption of First Commerce Options, see
"Treatment of First Commerce Options."
 
SURRENDER OF FIRST COMMERCE COMMON STOCK CERTIFICATES
 
     Upon the Effective Date and subject to the conditions described at
"Conditions to Consummation of the Merger," First Commerce's shareholders
(except to the extent that such holders perfect dissenters' rights under
applicable law) will automatically, and without further action by such
shareholders or by BancGroup, become owners of BancGroup Common Stock as
described herein. Outstanding certificates representing shares of the First
Commerce Common Stock will represent shares of BancGroup Common Stock.
Thereafter, upon surrender of the certificates formerly representing shares of
First Commerce Common Stock, the holders will be entitled to receive
certificates for the BancGroup Common Stock. Dividends on the shares of
BancGroup Common Stock will accumulate without interest and will not be
distributed to any former shareholder of First Commerce unless and until such
shareholder surrenders for cancellation his certificate for First Commerce
Common Stock. SunTrust Bank, Atlanta, Atlanta, Georgia, transfer agent for
BancGroup Common Stock, will act as the Exchange Agent with respect to the
shares of First Commerce Common Stock surrendered in connection with the Merger.
 
     A detailed explanation of these arrangements will be mailed to First
Commerce shareholders promptly following the Effective Date. STOCK CERTIFICATES
SHOULD NOT BE SENT TO THE EXCHANGE AGENT UNTIL SUCH NOTICE IS RECEIVED.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The Merger is intended to qualify as a "reorganization" for federal income
tax purposes under Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as
amended (the "Code"). The obligation of First Commerce to consummate the Merger
is conditioned on the receipt by First Commerce of an opinion from Coopers &
Lybrand L.L.P., which serves as BancGroup's independent public accountant, to
the effect that the Merger will constitute such a reorganization. The opinion
has been delivered to First Commerce. In delivering its opinion, Coopers &
Lybrand L.L.P., has received and relied upon certain representations contained
in certificates of officers of BancGroup and First Commerce and certain other
information, data, documentation and other materials as it deems necessary. The
tax opinion is based upon customary assumptions contained therein, including the
assumption that First Commerce has no knowledge of any plan or intention on the
part of the First Commerce shareholders to sell or dispose of BancGroup Common
Stock that would reduce their holdings to the number of shares having in the
aggregate a fair market value of less than 50% of the total fair market value of
the First Commerce Common Stock outstanding immediately upon the Merger.
 
     Neither First Commerce nor BancGroup intends to seek a ruling from the
Internal Revenue Service as to the federal income tax consequences of the
Merger. First Commerce's shareholders should be aware that the opinion will not
be binding on the Internal Revenue Service or the courts. First Commerce's
shareholders also should be aware that some of the tax consequences of the
Merger are governed by provisions of the Code as to
 
                                       19
<PAGE>   27
 
which there are no final regulations and little or no judicial or administrative
guidance. There can be no assurance that future legislation, administrative
rulings, or court decisions will not adversely affect the accuracy of the
statements contained herein.
 
     The tax opinion states that, provided the assumptions stated therein are
satisfied, the Merger will constitute a reorganization as defined in Section
368(a) of the Code and the following federal income tax consequences will result
to First Commerce's shareholders who exchange their shares of First Commerce
Common Stock for shares of BancGroup Common Stock:
 
          (i) No gain or loss will be recognized by First Commerce's
     shareholders on the exchange of shares of First Commerce Common Stock for
     shares of BancGroup Common Stock;
 
          (ii) The aggregate basis of BancGroup Common Stock received by each
     First Commerce shareholder (including any fractional shares of BancGroup
     Common Stock deemed received, but not actually received), will be the same
     as the aggregate tax basis of the shares of First Commerce Common Stock
     surrendered in exchange therefor;
 
          (iii) The holding period of the shares of BancGroup Common Stock
     received by each First Commerce shareholder will include the period during
     which the shares of First Commerce Common Stock exchanged therefor were
     held, provided that the shares of First Commerce Common Stock were a
     capital asset in the holder's hands as of the Effective Date;
 
          (iv) Cash payments received by each First Commerce shareholder in lieu
     of a fractional share of BancGroup Common Stock will be treated for federal
     income tax purposes as if the fractional share had been issued in the
     exchange and then redeemed by BancGroup. Gain or loss will be recognized on
     the redemption of the fractional share and generally will be capital gain
     or loss if the First Commerce Common Stock is a capital asset in the hands
     of the holder;
 
          (vi) No gain or loss will be recognized by First Commerce upon the
     transfer of its assets and liabilities to BancGroup. No gain or loss will
     be recognized by BancGroup upon the receipt of the assets and liabilities
     of First Commerce;
 
          (vii) The basis of the assets of First Commerce acquired by BancGroup
     will be the same as the basis of the assets in the hands of First Commerce
     immediately prior to the Merger;
 
          (viii) The holding period of the assets of First Commerce in the hands
     of BancGroup will include the period during which such assets were held by
     First Commerce; and
 
          (ix) A First Commerce shareholder who dissents and receives only cash
     pursuant to dissenters rights will recognize gain or loss. Such gain or
     loss will, in general, be treated as capital gain or loss, measured by the
     difference between the amount of cash received and the tax basis of the
     shares of First Commerce Common Stock converted, if the shares of First
     Commerce Common Stock were held as capital assets. However, a First
     Commerce shareholder who receives only cash may need to consider the
     effects of Section 302 and 318 of the Code in determining the federal
     income tax consequences of the transaction.
 
     Each First Commerce shareholder will be required to report on such
shareholder's federal income tax return for the fiscal year of such shareholder
in which the Merger occurs that such shareholder has received BancGroup Common
Stock in a reorganization.
 
     THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF ALL MATERIAL
FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO THE SHAREHOLDERS OF FIRST
COMMERCE, TO FIRST COMMERCE AND TO BANCGROUP AND DOES NOT PURPORT TO BE A
COMPLETE DESCRIPTION OF ALL POTENTIAL TAX EFFECTS OF THE MERGER. THE DISCUSSION
DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE RELEVANT TO A PARTICULAR
SHAREHOLDER SUBJECT TO SPECIAL TREATMENT UNDER CERTAIN FEDERAL INCOME TAX LAWS,
SUCH AS DEALERS IN SECURITIES, BANKS, INSURANCE COMPANIES, TAX-EXEMPT
ORGANIZATIONS, NON-UNITED STATES

PERSONS, STOCKHOLDERS WHO DO NOT HOLD THEIR SHARES OF FIRST COMMERCE COMMON
STOCK AS "CAPITAL ASSETS" WITHIN THE MEANING OF SECTION 1221 OF THE CODE, AND
SHAREHOLDERS WHO ACQUIRED THEIR SHARES OF FIRST COMMERCE COMMON STOCK PURSUANT
TO THE EXERCISE OF OPTIONS OR OTHERWISE AS COMPENSATION, NOR ANY CONSEQUENCES
ARISING UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN JURISDICTION. THE
DISCUSSION IS BASED UPON THE CODE, TREASURY REGULATIONS THEREUNDER AND
ADMINISTRATIVE RULINGS AND COURT DECISIONS AS OF THE DATE HEREOF. ALL OF THE
FOREGOING IS SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING
VALIDITY OF THIS DISCUSSION. FIRST COMMERCE SHAREHOLDERS ARE URGED TO CONSULT
THEIR OWN TAX ADVISORS CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL AND
FOREIGN TAX CONSEQUENCES OF THE MERGER TO THEM.
 
OTHER POSSIBLE CONSEQUENCES
 
     If the Merger is consummated, the shareholders of First Commerce, a Florida
corporation, will become shareholders of BancGroup, a Delaware business
corporation.

and privileges attaching to First Commerce Common Stock as compared with
BancGroup Common Stock, see "COMPARATIVE RIGHTS OF STOCKHOLDERS."
 
CONDITIONS TO CONSUMMATION OF THE MERGER
 
     The parties' obligation to consummate the Merger is subject to the
satisfaction (or waiver, to the extent permitted by law) of various conditions
set forth in the Agreement.
 
     The obligations of First Commerce and BancGroup to consummate the Merger
are conditioned upon, among other things, (i) the approval of the Agreement by
the holders of at least a majority of the outstanding shares of First Commerce
Common Stock; (ii) the approval of the Merger by the Federal Reserve and
approval of the Bank Merger by the Alabama Department and the Federal Reserve;
(iii) the absence of pending or threatened litigation with a view to restraining
or prohibiting consummation of the Merger or in which it is sought to obtain
divestiture, rescission or damages in connection with the Merger; (iv) the
absence of any investigation by any governmental agency which might result in
any such proceeding; (v) consummation of the Merger no later than November 30,
1997; and (vi) receipt of opinions of counsel regarding certain matters.
 
     The obligation of First Commerce to consummate the Merger is further
subject to several other conditions, including: (i) the absence of any material
adverse change in the financial condition or affairs of BancGroup; (ii) the
shares of BancGroup Common Stock to be issued under the Agreement shall have
been approved for listing on the NYSE; and (iii) the accuracy in all material
respects of the representations and warranties of BancGroup contained in the
Agreement and the performance by BancGroup of all of its covenants and
agreements under the Agreement.
 
     The obligation of BancGroup to consummate the Merger is subject to several
other conditions, including: (i) the absence of any material adverse change in
the financial condition or affairs of First Commerce; (ii) the holders of not
more than 15% of the outstanding shares of First Commerce Common Stock shall
have exercised dissenters' rights with respect to their shares; (iii) the
accuracy in all material respects of the representations and warranties of First
Commerce contained in the Agreement, and the performance by First Commerce of
all of its covenants and agreements under the Agreement; and (iv) the receipt by
BancGroup of certain undertakings from holders of First Commerce Common Stock
who may be deemed to be "affiliates" of First Commerce pursuant to the rules of
the Commission.
 
     It is anticipated that the foregoing conditions, as well as certain other
conditions contained in the Agreement, such as the receipt of certificates of
officers of each party as to compliance with the Agreement, and satisfaction of
each party of all representations, warranties and covenants, will be satisfied.
The Agreement
 
                                       21
<PAGE>   29
 
provides that First Commerce and BancGroup may waive all conditions to their
obligations to consummate the Merger, other than the receipt of the requisite
approvals of regulatory authorities and First Commerce shareholder approval of
the Merger. In making any decision regarding a waiver of one or more conditions
to consummation of the Merger or an amendment of the Agreement, the Boards of
Directors of First Commerce and BancGroup would be subject to the fiduciary duty
standards imposed upon such boards by relevant law that would require such
boards to act in the best interests of their respective shareholders.
 
AMENDMENT OR TERMINATION
 
     The Boards of Directors of BancGroup and First Commerce may agree to amend
or terminate the Agreement before or after approval by the shareholders of First
Commerce. However, the Board of Directors of First Commerce may not amend the
Agreement which would alter the Merger Consideration or which, in the opinion of
the Board of Directors of First Commerce, would adversely affect the rights of
the shareholders of First Commerce, unless such amendments are approved by a
majority of the outstanding shares of First Commerce Common Stock. Such
amendments may require the filing of an amendment of the Registration Statement,
of which this Prospectus forms a part, with the Commission. See "Conditions to
Consummation of the Merger."
 
REGULATORY APPROVALS
 
     Prior to the Merger, a 10-day prior notification to the Federal Reserve
will be provided pursuant to Section 3 of the BHCA and the regulations
promulgated pursuant thereto. It is contemplated that the Merger will occur
simultaneously with the Bank Merger. The approval of the Federal Reserve and the
Alabama Department must be obtained prior to consummation of the Bank Merger.
Applications were filed with the Federal Reserve and the Alabama Department on
or about April 21, 1997. The regulatory approval process is expected to take
approximately two months from that date.
 
     Federal Reserve Notification.  Under limited circumstances, approval of the
Merger by the Federal Reserve under Section 3 of the BHCA is not required. More
specifically, the Merger would not require Federal Reserve approval if: (1) the
Bank is merged into a BancGroup bank subsidiary simultaneously with the Merger;
(2) the Bank's merger into a BancGroup bank subsidiary requires the prior
approval of a federal supervisory agency under the Bank Merger Act; (3) the
transaction does not involve an acquisition subject to Section 4 of the BHCA;
(4) both before and after the transaction, BancGroup meets the Federal Reserve's
capital adequacy guidelines; and (5) BancGroup provides written notice of the
transaction to the Federal Reserve at least ten days prior to the transaction,
and during that period, the Federal Reserve does not require an application
under Section 3 of the BHCA. It is anticipated that BancGroup will satisfy the
foregoing requirements, and, absent Federal Reserve action pursuant to item (5)
above, an application with the Federal Reserve pursuant to Section 3 of the BHCA
will not be required.
 
     In the event the Federal Reserve requires an application pursuant to
Section 3 of the BHCA, approval of the Federal Reserve would be required prior
to the Merger. Pursuant to Section 3 of the BHCA, and the regulations
promulgated pursuant thereto, the Federal Reserve must withhold approval of the
Merger if it finds that the transaction will result in a monopoly or be in
furtherance of any combination or conspiracy to monopolize or attempt to
monopolize the business of banking in any part of the United States. In
addition, the Federal Reserve may not approve the Merger if it finds that the
effect thereof may be substantially to lessen competition in any section of the
country, or tend to create a monopoly, or would in any other manner be in
restraint of trade, unless it finds that the anti-competitive effects of the
Merger are clearly outweighed by the probable effect of the Merger in meeting
the convenience and needs of the communities to be served. The Federal Reserve
will also take into consideration the financial condition and managerial
resources of BancGroup, its subsidiaries, any banks related to BancGroup through
common ownership or management, and the Bank. Finally, the Federal Reserve will
consider the compliance records of BancGroup's subsidiaries under the Community
Reinvestment Act.
 
     The BHCA provides for the publication of notice and public comment on the
application and authorizes the Federal Reserve to permit interested parties to
intervene in the proceedings. If an interested party is
 
                                       22
<PAGE>   30
 
permitted to intervene, such intervention could delay the regulatory approvals
required for consummation of the Merger. Section 11 of the BHCA imposes a
waiting period which prohibits the consummation of the Merger, in ordinary
circumstances, for a period ranging from 15-30 days following the Federal
Reserve's approval of the Merger. During such period, the United States
Department of Justice, should it object to the Merger for antitrust reasons, may
challenge the consummation of the Merger.
 
     Alabama State Banking Department Approval.  The Bank Merger must be
approved by the Alabama Department pursuant to applicable provisions of the
Alabama Banking Code. If the Superintendent of the Alabama Department finds that
(1) the proposed transaction will not be detrimental to the safety and soundness
of the bank resulting from the Bank Merger, (2) any new officers and directors
of the resulting bank are qualified by character, experience, and financial
responsibility to direct and manage the resulting bank, and (3) the proposed
Bank Merger is consistent with the convenience and needs of the communities to
be served by the resulting bank in the State of Alabama and is otherwise in the
public interest, the Bank Merger will be approved by the Superintendent.
 
     Federal Reserve Approval.  On March 14, 1997, Colonial Bank, a
state-chartered non-member bank, the primary federal regulator of which is
currently the Federal Deposit Insurance Corporation, filed an application for
membership in the Federal Reserve. Subject to Federal Reserve approval of the
pending membership application, it is anticipated that Colonial Bank will become
a member of the Federal Reserve on or about June 1, 1997. As the primary federal
regulator of state-chartered banks that are members of the Federal Reserve, the
Federal Reserve will become the primary federal regulator of Colonial Bank upon
its admission to membership in the Federal Reserve. In that the Bank Merger Act
requires that a bank merger be approved by the primary federal regulator of the
resulting bank, and in that Colonial Bank will be the bank resulting from the
Bank Merger, the Federal Reserve's approval of the Bank Merger must be obtained.
A delay in the receipt of the Federal Reserve's approval of the membership
application or the Federal Reserve's disapproval of such application could
significantly impact the timing of the Bank Merger.
 
     The Federal Reserve is prohibited from approving the Bank Merger if it
would result in a monopoly or would be in furtherance of any combination or
conspiracy to monopolize or to attempt to monopolize the business of banking in
any part of the United States. In addition, the Federal Reserve is prohibited
from approving the Bank Merger if its effect, in any section of the country,
would be substantially to lessen competition, or to tend to create a monopoly,
or which in any other manner would be in restraint of trade, unless it finds
that the anti-competitive effects of the Bank Merger are clearly outweighed in
the public interest by the probable effect of the Bank Merger in meeting the
convenience and needs of the community to be served. The Federal Reserve is
required to take into consideration the financial and managerial resources and
future prospects of the existing and proposed institutions, and the convenience
and needs of the community to be served.
 
     In that the Bank Merger constitutes an interstate bank merger, certain
additional requirements are applicable to the Bank Merger. For example, subject
to certain exceptions, the Federal Reserve is prohibited from approving the Bank
Merger if Colonial Bank materially fails to comply with filing requirements
imposed by the Florida Department of Banking and Finance for interstate bank
merger transactions. In addition, the Federal Reserve is prohibited from
approving the Bank Merger if the bank resulting from the Bank Merger, including
all insured depository institutions which are affiliates of such resulting bank,
upon consummation of the transaction, would control more than 10% of the total
amount of deposits of insured depository institutions in the United States. The
Federal Reserve is also prohibited from approving the Bank Merger if either
party to the Bank Merger has a branch in any state in which any other bank
involved in the Bank Merger has a branch, and the resulting bank, upon
consummation of the Bank Merger, would control 30% or more of the total amount
of deposits of insured depository institutions in any such state. Finally, the
Federal Reserve may approve the interstate bank merger only if each bank
involved in the transaction is adequately capitalized as of the date the
application is filed, and the Federal Reserve determines that the resulting bank
will continue to be adequately capitalized and adequately managed upon
consummation of the Bank Merger.
 
     The Bank Merger Act imposes a waiting period which prohibits consummation
of the Bank Merger, in ordinary circumstances, for a period ranging from 15-30
days following the Federal Reserve's approval of the
 
                                       23
<PAGE>   31
 
Bank Merger. During such period, the United States Department of Justice, should
it object to the Merger for antitrust reasons, may challenge the consummation of
the Merger.
 
     The Agreement provides that the obligation of each of BancGroup and First
Commerce to consummate the Merger is conditioned upon the receipt of all
necessary regulatory approvals, including the approval of the Federal Reserve
and the Alabama Department, and the absence in such approvals of any condition
or restriction which in the reasonable good faith judgment of the Board of
Directors of BancGroup or First Commerce would so materially adversely impact
the economic benefits of the transaction as contemplated by the Agreement so as
to render inadvisable the consummation of the Merger. There can be no assurance
that the Federal Reserve or the Alabama Department will approve BancGroup's
applications to acquire First Commerce, and, if such approvals are received,
that such approvals will not be conditioned upon terms and conditions that would
cause the parties to abandon the Merger.
 
     Any approval received from the banking agencies reflects only their view
that the Merger does not contravene applicable competitive standards imposed by
law, and that the Merger is consistent with regulatory policies relating to
safety and soundness. THE APPROVAL OF THE BANKING AGENCIES IS NOT AN ENDORSEMENT
OR RECOMMENDATION OF THE MERGER.
 
     BancGroup is not aware of any other governmental approvals or actions that
may be required for consummation of the Merger except for the Federal Reserve
and the Alabama Department approvals, described above. Should any such approval
or action be required, it is presently contemplated that such approval or action
would be sought.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
     The Agreement contains certain restrictions on the conduct of the business
of First Commerce pending consummation of the Merger. The Agreement prohibits
First Commerce from taking any of the following actions, prior to the Effective
Date, subject to certain limited exceptions previously agreed to by the parties,
without the prior written approval of BancGroup:
 
          (i) Issuing, delivering or agreeing to issue or deliver any stock,
     bonds or other corporate securities (whether authorized and unissued or
     held in the treasury), except shares of First Commerce Common Stock issued
     upon the exercise of First Commerce Options;
 
          (ii) Borrowing or agreeing to borrow any funds or incurring or
     becoming subject to, any liability (absolute or contingent) except
     borrowings, obligations and liabilities incurred in the ordinary course of
     business and consistent with past practice;
 
          (iii) Paying any material obligation or liability (absolute or
     contingent) other than current liabilities reflected in or shown on the
     most recent balance sheet and current liabilities incurred since that date
     in the ordinary course of business and consistent with past practice;
 
          (iv) Declaring or making or agreeing to declare or make, any payment
     of dividends or distributions of any assets of any kind whatsoever to
     shareholders, or purchasing or redeeming or agreeing to purchase or redeem,
     any of its outstanding securities;
 
          (v) Except in the ordinary course of business, selling or transferring
     or agreeing to sell or transfer, any of its assets, property or rights or
     canceling, or agreeing to cancel, any debts or claims;
 
          (vi) Except in the ordinary course of business, entering or agreeing
     to enter into any agreement or arrangement granting any preferential rights
     to purchase any of its assets, property or rights or requiring the consent
     of any party to the transfer and assignment of any of its assets, property
     or rights;
 
          (vii) Waiving any rights of value which in the aggregate are material;
 
          (viii) Except in the ordinary course of business, making or permitting
     any amendment or termination of any contract, agreement or license to which
     it is a party if such amendment or termination is material considering its
     business as a whole;
 
                                       24
<PAGE>   32
 
          (ix) Except in accordance with past practice, making any accrual or
     arrangement for or payment of bonuses or special compensation of any kind
     or any severance or termination pay to any present or former officer or
     employee;
 
          (x) Except in accordance with past practice, increasing the rate of
     compensation payable to or to become payable to any of its officers or
     employees or making any material increase in any profit-sharing, bonus,
     deferred compensation, savings, insurance, pension, retirement or other
     employee benefit plan, payment or arrangement made to, for or with any of
     its officers or employees;
 
          (xi) Failing to operate its business in the ordinary course so as to
     preserve its business intact and to preserve the goodwill of its customers
     and others with whom it has business relations; and
 
          (xii) Entering into any other material transaction other than in the
     ordinary course of business.
 
     The Agreement provides that prior to the Effective Date, no director or
officer of First Commerce or any of its subsidiaries shall, directly or
indirectly, own, manage, operate, join, control, be employed by or participate
in the ownership, proposed ownership, management, operation or control of or be
connected in any manner with, any business, corporation or partnership which is
competitive to the business of First Commerce or its subsidiaries.
 
     The Agreement also provides that (i) First Commerce will consult with
BancGroup respecting loan requests in excess of $100,000 that are not
single-family residential loan requests and respecting other loan requests
outside the normal course of business, and (ii) First Commerce will consult with
BancGroup respecting business issues that First Commerce believes should be
brought to the attention of BancGroup.
 
COMMITMENTS WITH RESPECT TO OTHER OFFERS
 
     Until the termination of the Agreement, and except for the Merger, neither
First Commerce nor any of its directors or officers (or any person representing
any of the foregoing) may solicit or encourage inquiries or proposals with
respect to, furnish any information relating to or participate in any
negotiations or discussions concerning, any acquisition or purchase of all or of
a substantial portion of the assets of, or of a substantial equity interest in,
First Commerce or any business combination involving First Commerce
(collectively, an "Acquisition Proposal") other than as contemplated by the
Agreement. First Commerce is required to notify BancGroup immediately if any
such inquiries or proposals are received by First Commerce, if any such
information is requested from First Commerce, or if any such negotiations or
discussions are sought to be initiated with First Commerce. First Commerce is
required to instruct its officers, directors, agents or affiliates or their
subsidiaries to refrain from doing any of the above. First Commerce may
communicate information about an Acquisition Proposal to its shareholders if and
to the extent that legal counsel provides a written opinion to First Commerce (a
copy of which shall be provided in advance to BancGroup) that it is required to
do so in order to comply with its legal obligations.
 
     If (i) an Acquisition Proposal is submitted to and approved by the
shareholders of First Commerce at any time prior to the Effective Date; or (ii)
an Acquisition Proposal is received by First Commerce or is made directly to the
shareholders of First Commerce at any time prior to the termination of the
Agreement (except for a termination by First Commerce for a breach of the
Agreement by BancGroup) and, in the case of (i) or (ii), such Acquisition
Proposal is closed, then First Commerce will pay to BancGroup a termination fee
in an amount equal to 10% of the shareholders' equity of First Commerce as of
the end of the month preceding such payment, as liquidated damages, and not as a
penalty, and, upon the payment in full thereof, the Agreement will be terminated
and no party to the Agreement will have any further liability under the
Agreement.
 
INDEMNIFICATION
 
     BancGroup has agreed to indemnify present and former directors and officers
of First Commerce and the Bank against liabilities arising out of actions or
omissions occurring at or prior to the Effective Date to the extent provided in
the Florida Business Corporation Act and First Commerce's Articles of
Incorporation and Bylaws.

RIGHTS OF DISSENTING SHAREHOLDERS
 
     Holders of First Commerce Common Stock as of the Record Date are entitled
to dissenters' rights of appraisal under Florida law. Consummation of the Merger
is subject to, among other things, the holders of no more than 15% of the
outstanding First Commerce Common Stock electing to exercise their dissenters'
rights. Pursuant to Section 607.1320 of the FBCA, a First Commerce shareholder
who does not wish to accept the shares of BancGroup Common Stock to be received
pursuant to the terms of the Agreement may dissent from the Merger and elect to
receive the fair value of his shares as of the day prior to the date the Merger
is approved by First Commerce shareholders. Such fair value is exclusive of any
appreciation or depreciation in anticipation of the Merger, unless exclusion
would be inequitable.
 
     In order to exercise appraisal rights, a dissenting shareholder of First
Commerce (a "Dissenting Shareholder") must fully comply with the statutory
procedures of Sections 607.1320, 607.1301 and 607.1302 of the FBCA, which are
summarized below. Such Sections are attached hereto as Appendix C. Shareholders
of First Commerce are urged to read such Sections in their entirety and to
consult with their legal advisors. Each shareholder of First Commerce who
desires to assert his or her appraisal rights is cautioned that failure on his
or her part to adhere strictly to the requirements of Florida law in any regard
will cause a forfeiture of any appraisal rights. The following summary of
Florida law is qualified in its entirety by reference to the full text of the
provisions of the FBCA attached hereto as Appendix C.
 
     To exercise appraisal rights,
 
     1. A Dissenting Shareholder must file with First Commerce, prior to the
       taking of the vote on the Merger, a written notice of intent to demand
       payment for his or her shares if the Merger is effectuated. A vote
       against the Merger will not alone be deemed to be the written notice of
       intent to demand payment. A Dissenting Shareholder need not vote against
       the Merger, but cannot vote for the Merger.
 
     2. Within ten days after the vote on the Merger is taken, First Commerce
       must give written notice of the authorization of the Merger, if obtained,
       to each First Commerce shareholder who filed notice of intent to demand
       payment for his shares. WITHIN TWENTY DAYS AFTER THE GIVING OF THE
       FOREGOING NOTICE BY FIRST COMMERCE, EACH DISSENTING SHAREHOLDER MUST FILE
       WITH FIRST COMMERCE A NOTICE OF ELECTION TO DISSENT, STATING HIS OR HER
       NAME AND ADDRESS, THE NUMBER OF SHARES AS TO WHICH HE OR SHE DISSENTS AND
       A DEMAND FOR PAYMENT OF THE FAIR VALUE OF HIS OR HER SHARES. ANY
       DISSENTING SHAREHOLDER FAILING TO FILE SUCH ELECTION WITHIN THE PERIOD
       WILL LOSE HIS OR HER APPRAISAL RIGHTS AND BE BOUND BY THE TERMS OF THE
       AGREEMENT. A Dissenting Shareholder filing an election to dissent must
       also deposit the certificate(s) representing his or her shares with First
       Commerce simultaneously with the filing of the election.
 
     3. Upon filing a notice of election to dissent, a Dissenting Shareholder
       shall thereafter be entitled only to payment pursuant to the procedure
       set forth in the applicable sections of FBCA and shall not be entitled to
       vote or to exercise any other rights of a shareholder. A notice of
       election may be withdrawn in writing by the Dissenting Shareholder at any
       time before an offer is made by First Commerce to pay for shares. Upon
       such withdrawal, the right of the Dissenting Shareholder to be paid the
       fair value of his or her shares will cease, and he or she will be
       reinstated as a shareholder.
 
     4. Within ten days after the expiration of the period in which a Dissenting
       Shareholder may file notice of election to dissent, or within ten days
       after the Effective Date of the Merger, whichever is later (but in no
       event later than ninety days after the Merger is approved), First
       Commerce (or BancGroup after the Effective Date) must make a written
       offer to each Dissenting Shareholder who has made demand for appraisal
       for his or her shares at a price deemed by First Commerce to be the fair
       value thereof.
 
     5. If, within thirty days after the making of such offer, the Dissenting
       Shareholder accepts the offer, payment for the shares of the Dissenting
       Shareholder is to be made within ninety days after the making of such
       offer or the effective date of the Merger, whichever is later. Upon
       payment of the agreed value, the Dissenting Shareholder will cease to
       have any interest in such shares.
 
                                       26
<PAGE>   34
 
     6.If First Commerce (or BancGroup, if appropriate) fails to make such
       offer within the period specified above or if it makes an offer and a
       Dissenting Shareholder fails to accept the same within a period of 30
       days thereafter, then First Commerce, within 30 days after receipt of
       written demand from any Dissenting Shareholder given within 60 days after
       the date on which the Merger was effected, shall, or at its election at
       any time within such period of 60 days may, file an action in any court
       of competent jurisdiction in Polk County requesting that the fair value
       of such shares be determined by the Court.
 
     7.If First Commerce fails to institute such proceeding within the
       above-prescribed period, any Dissenting Shareholder may do so in the name
       of First Commerce. A copy of the initial pleading will be served on each
       Dissenting Shareholder. First Commerce is required to pay each Dissenting
       Shareholder the amount found to be due within ten days after final
       determination of the proceedings. The judgment of the court is payable
       only upon and concurrently with the surrender to First Commerce of the
       certificate(s) representing the shares. Upon payment of the judgment, the
       Dissenting Shareholder ceases to have any interest in such shares.
 
     8.The costs and expenses of the court proceeding are determined by the
       court and will be assessed against First Commerce (or BancGroup, if
       appropriate) except that all or any part of such costs and expenses may
       be apportioned and assessed against any Dissenting Shareholders who are
       parties to the proceeding and to whom First Commerce has made an offer to
       pay for their shares, if the court finds their refusal to accept such
       offer to have been arbitrary, vexatious or not in good faith. Expenses
       include reasonable compensation for, and expenses of, appraisers, but
       shall exclude the fees and expenses of counsel for, and experts employed
       by, any party. If the value of the shares, as determined by the court,
       materially exceeds the amount that First Commerce offered to pay for the
       shares then the court may, in its discretion, award to any Dissenting
       Shareholder who is a party to the proceedings, such sum as the court may
       determine to be reasonable compensation to any expert(s) employed by the
       Dissenting Shareholder in the proceeding.
 
     The foregoing discussion is only a summary of the provisions of Florida law
and does not purport to be complete and is qualified in its entirety by
reference to the provisions of Florida law, which are attached hereto as
Appendix C. Successful assertion by First Commerce shareholders of their
dissenters' appraisal rights is dependent upon compliance with the requirements
described above. Non-compliance with any provision will result in a failure to
perfect those rights and the loss of any opportunity to receive payment for
shares pursuant to an appraisal.
 
     BECAUSE OF THE COMPLEXITY OF THE PROVISIONS OF THE FLORIDA LAW RELATING TO
DISSENTERS' APPRAISAL RIGHTS, SHAREHOLDERS WHO ARE CONSIDERING DISSENTING FROM
THE MERGER ARE URGED TO CONSULT THEIR OWN LEGAL ADVISERS.
 
RESALE OF BANCGROUP COMMON STOCK ISSUED IN THE MERGER
 
     The issuance of the shares of BancGroup Common Stock pursuant to the Merger
(including any shares to be issued pursuant to First Commerce Options) has been
registered under the Securities Act of 1933 (the "Securities Act"). As a result,
shareholders of First Commerce who are not "affiliates" of First Commerce (as
such term is defined under the Securities Act) may resell, without restriction,
all shares of BancGroup Common Stock which they receive in connection with the
Merger. Under the Securities Act, affiliates of First Commerce are subject to
restrictions on the resale of the BancGroup Common Stock which they receive in
the Merger.
 
     The BancGroup Common Stock received by affiliates of First Commerce who do
not also become affiliates of BancGroup after the consummation of the Merger may
not be sold except pursuant to an effective Registration Statement under the
Securities Act covering such shares or in compliance with Rule 145 promulgated
under the Securities Act or another applicable exemption from the registration
requirements of the Securities Act. Generally, Rule 145 permits BancGroup Common
Stock held by such shareholders to be sold in accordance with certain provisions
of Rule 144 under the Securities Act. In general, these provisions of Rule 144
permit a person to sell on the open market in brokers or certain other
transactions within any three-
 
                                       27
<PAGE>   35
 
month period a number of shares that does not exceed the greater of 1% of the
then outstanding shares of BancGroup Common Stock or the average weekly trading
volume in BancGroup Common Stock reported on the NYSE during the four calendar
weeks preceding such sale. Sales under Rule 144 are also subject to the
availability of current public information about BancGroup. The restrictions on
sales will cease to apply under most circumstances once the former First
Commerce affiliate has held the BancGroup Common Stock for at least one year.
BancGroup Common Stock held by affiliates of First Commerce who become
affiliates of BancGroup, if any, will be subject to additional restrictions on
the ability of such persons to resell such shares.
 
     First Commerce will provide BancGroup with such information as may be
reasonably necessary to determine the identity of those persons (primarily
officers and directors) who may be deemed to be affiliates of First Commerce.
First Commerce will also obtain from each such person a written undertaking to
the effect that no sale or transfer will be made of any shares of BancGroup
Common Stock by such person except pursuant to Rule 145 or pursuant to an
effective registration statement or an exemption from registration under the
Securities Act. Receipt of such an undertaking is a condition to BancGroup's
obligation to close the Merger. If such undertakings are not received and
BancGroup waives receipt of such condition, the certificates for the shares of
BancGroup Common Stock to be issued to such person will contain an appropriate
restrictive legend and appropriate stock transfer orders will be given to
BancGroup's stock transfer agent.
 
ACCOUNTING TREATMENT
 
     The acquisition of First Commerce will be treated as a "purchase"
transaction by BancGroup. Accordingly, the purchase price will be assigned to
the fair value of the net tangible assets acquired and any purchase price in
excess thereof will be assigned to intangibles. The valuation of intangibles, if
any, will be made as of the Effective Date of the Merger. Intangibles, in the
approximate amount of $6 million, will be amortized by charges or credits to
future earnings over a period of approximately twenty years.
 
NYSE REPORTING OF BANCGROUP COMMON STOCK ISSUED IN THE MERGER
 
     Sales of BancGroup Common Stock to be issued in the Merger in exchange for
First Commerce Common Stock will be reported on the NYSE.
 
TREATMENT OF FIRST COMMERCE OPTIONS
 
     ASSUMPTION OF OPTIONS.  As of the date of this Prospectus, First Commerce
had granted options and stock purchase warrants (collectively, the "First
Commerce Options"), which entitle the holders thereof to acquire up to 321,215
shares of First Commerce Common Stock. On the Effective Date, BancGroup will
assume all First Commerce Options outstanding, and each such option will
represent the right to acquire BancGroup Common Stock on substantially the same
terms applicable to the First Commerce Options. The registration statement
registering the shares of BancGroup Common Stock issued pursuant to the Merger
also registers the shares of BancGroup Common Stock to be issued upon the
exercise of the First Commerce Options assumed by BancGroup. The number of
shares of BancGroup Common Stock to be issued pursuant to such options will
equal the number of shares of First Commerce Common Stock subject to such First
Commerce Options multiplied by the Exchange Ratio, provided that no fraction of
shares of BancGroup Common Stock will be issued and the number of shares of
BancGroup Common Stock to be issued upon the exercise of First Commerce Options,
if a fractional share exists, will equal the number of whole shares obtained by
rounding to the nearest whole number, giving account to such fraction, or else
such fractional interest will be paid in cash. The exercise price for the
acquisition of BancGroup Common Stock will be the exercise price for each share
of First Commerce Common Stock subject to such options divided by the Exchange
Ratio, adjusted appropriately for any rounding to whole shares that may be done.
 
     As an alternative to assumption by BancGroup, holders of First Commerce
Options may elect by giving written notice to First Commerce before the
Effective Date to be paid in cash the difference between the exercise price for
such options and the value of such option determined at the Effective Date based
upon the Exchange Ratio.
 
                                       28
<PAGE>   36
 
     The First Commerce Options are issuable pursuant to the First Commerce 1992
Stock Option Plan for Directors (the "Director Plan"), the 1992 Stock Option
Plan for Officers (the "Option Plan") and the Stock Purchase Warrants (the
"Warrants") (collectively the "Plans").
 
     The Plans are not qualified under Section 401(a) of the Internal Revenue
Code of 1986, as amended, nor are they subject to the Employee Retirement Income
Security Act of 1974. First Commerce Options are not transferrable except under
the laws of descent and distribution. No further options will be granted under
the Plans after the Merger. A total of 26 persons currently hold First Commerce
Options.
 
     TAX CONSEQUENCES -- INCENTIVE OPTIONS.  Options issued under the Option
Plan may qualify as "incentive stock options," under Section 422 of the Internal
Revenue Code of 1986, as amended. If such options so qualify under the Internal
Revenue Code no income will result to a grantee of any such option upon the
granting or exercising of an option by the grantee, and BancGroup will not be
entitled to a tax deduction by reason of such grant or exercise.
 
     If, after exercising the option, the employee holds the stock obtained
through exercise for at least two years after the date of option grant and at
least one year after the stock was obtained, the employee's gain (if any) on
selling the stock will generally be treated as a long term capital gain.
Generally, the employee's alternative minimum taxable income for minimum tax
purposes will be increased by the difference between the option price and the
fair market value of the stock on the date of exercise.
 
     If the holding period requirements just stated are not met, then any gain
on the sale of the stock will be taxed partly or entirely at ordinary income tax
rates. If the stock is held for less than the required holding period, then the
difference between the option exercise price and the fair market value of the
stock on the date of exercise will be taxed at ordinary income tax rates. The
gain equal to the increase in the fair market value of the stock after the date
of exercise of the option will generally be taxed as capital gain.
 
     It should be understood that the holding periods discussed above relate
only to federal income tax treatment and not to any securities law restrictions
that may apply to the sale of shares obtained through an option.
 
     TAX CONSEQUENCES -- NON QUALIFIED OPTIONS.  Certain options issued under
the Option Plan and the Director Plan that are issued as nonqualified options
are not "incentive stock options" under Section 422 of the Internal Revenue Code
of 1986, as amended. Thus, upon the exercise of such an option, ordinary income
will result to the grantee equal to the difference between the price of the
option and the fair market value of the stock subject to the option at the date
of exercise. BancGroup, however, will be entitled to a tax deduction equal to
the amount of ordinary income accruing to the optionee.
 
     TAX CONSEQUENCES -- WARRANTS.  If the warrants were issued in connection
with the performance of services, the assumption of the warrants should be
treated in the same fashion as the tax consequences of nonqualified options
discussed above. If, however, the warrants were not issued in connection with
the performance of services, the assumption of those warrants by BancGroup would
result in the recognition of taxable income by the holders of the warrants.
 
     The foregoing statements concerning federal income tax treatment are
necessarily general and may not apply in a particular instance. Option holders
should contact their own professional tax advisors for advice concerning their
particular tax situation and any changes in the tax law since the date of this
Prospectus.
 
     ADMINISTRATION.  The shares of stock to be delivered upon the exercise of
First Commerce Options will be made available, after the Merger, from the
authorized but unissued shares of BancGroup's Common Stock or shares reacquired
by BancGroup in the open market.
 
     The Plans are to be administered, after the Merger, by the Personnel and
Compensation Committee (the "Committee") of the Board of Directors of BancGroup.
All members of the Committee are directors of BancGroup. The Chairman of the
Committee, John C. H. Miller, Jr., receives employee-related compensation from
BancGroup and holds options under BancGroup's stock option plans. Mr. Miller is
a member of a law firm that performs legal services for BancGroup. See "LEGAL
OPINIONS." Another member of the Committee, Jack H. Rainer, is Chairman of
Bankers Credit Life Insurance Company, which provides credit
 
                                       29
<PAGE>   37
 
life insurance on certain loans made by Colonial Bank, BancGroup's Alabama bank
subsidiary. The members of the Committee serve at the pleasure of the Board of
Directors of BancGroup. The Committee shall interpret the Plans and resolve
questions presented by holders of options under the Plans. Requests for
information or questions about the Plans should be directed to BancGroup's
Corporate Secretary, at the offices of BancGroup, Post Office Box 1108, One
Commerce Street, Montgomery, Alabama 36102, telephone: (334) 240-5000.
 
     EXERCISE OF OPTIONS.  After a First Commerce Option becomes exercisable in
accordance with its terms, it may be exercised by the holder by giving written
notice to BancGroup on a form provided by BancGroup and by paying to BancGroup
in cash the exercise price of the shares to be acquired under the option.
Payment may be made to BancGroup by cash, check, bank draft, or money order, or,
if the Committee agrees in a particular instance, by delivering BancGroup stock
already owned by the option holder. The period during which an option may be
exercised is stated in the agreement respecting each grant of options.
 
     TERMINATION OF OPTIONS.  Options under the Option Plan and the Director
Plan may not be exercised after 10 years from the date of grant and may be
exercised at any time, but must be exercised no later than within (1) 90 days
after termination of a holders' employment or directorship as applicable; or (2)
within six months after termination due to permanent and total disability; or
(3) within one year after the holder's death. Options terminate in 2002.
 
     Warrants must be exercised on or before 2 p.m., May 15, 1999.
 
     AMENDMENT AND OTHER MATTERS.  BancGroup's Board of Directors may at any
time amend the Plans, except that no amendment may make any change in any option
already granted which would adversely affect the rights of any participant.
 
     It is not anticipated that BancGroup will make any reports to option
holders regarding the amount or status of First Commerce Options held. Option
holders may obtain such information from BancGroup at the address given above.
 
                    COMPARATIVE MARKET PRICES AND DIVIDENDS
 
BANCGROUP
 
     BancGroup Common Stock is listed for trading on the NYSE. The Common Stock
was first listed on the NYSE on February 24, 1995. Prior to February 21, 1995,
BancGroup had two classes of common stock outstanding, Class A and Class B. The
Class B was not publicly traded. The Class A Common Stock was traded in the
over-the-counter market and quoted on the NASDAQ National Market System. The
BancGroup Class A Common Stock had more limited voting rights than the BancGroup
Class B Common Stock. The Class A and Class B Common Stock were reclassified
into one class of Common Stock on February 21, 1995, and the Class A Common
Stock ceased to be quoted on NASDAQ on February 24, 1995.

(1) Price and dividends have been restated to reflect the impact of a
    two-for-one stock split effected in the form of a 100% stock dividend paid
    February 11, 1997.
 
     On February 14, 1997, the business day immediately prior to the public
announcement of the Merger, the closing price as reported on the NYSE of the
BancGroup Common Stock was $22 7/8 per share.
 
     At December 31, 1996, BancGroup's subsidiaries accounted for approximately
98% of BancGroup's consolidated assets. BancGroup derives substantially all of
its income from dividends received from its subsidiaries. Various statutory
provisions and regulatory policies limit the amount of dividends the subsidiary
banks may pay without regulatory approval. In addition, federal statutes
restrict the ability of subsidiary banks to make loans to BancGroup, and
regulatory policies may also restrict such dividends.
 
FIRST COMMERCE
 
     First Commerce.  There is no established public trading market for the
First Commerce Common Stock. The shares of First Commerce Common Stock are not
actively traded, and such trading activity, as it occurs, takes place in
privately negotiated transactions. Management of First Commerce is aware of
certain transactions in shares of First Commerce that have occurred since
January 1, 1995, although the trading prices of all stock transactions are not
known. The following sets forth the trading prices for the shares of First

                     BANCGROUP CAPITAL STOCK AND DEBENTURES
 
     BancGroup's authorized capital stock consists of 100,000,000 shares of
BancGroup Common Stock, par value $2.50 per share, and 1,000,000 shares of its
Preference Stock, par value $2.50 per share. As of March 1, 1997, there were
issued and outstanding a total of 38,955,210 shares of BancGroup Common Stock.
No shares of Preference Stock are issued and outstanding. BancGroup issued in
1986 $28,750,000 in principal amount of its 7 1/2% Convertible Subordinated
Debentures due 2011 (the "1986 Debentures") of which $7,187,000 were outstanding
as of December 31, 1996 and convertible at any time into 512,800 shares of
BancGroup Common Stock, subject to adjustment. There are 1,605,010 shares of
BancGroup Common Stock subject to issue upon exercise of options under
BancGroup's stock option plans. In addition to BancGroup Common Stock to be
issued in the Merger, BancGroup will issue additional shares of its Common Stock
in pending acquisitions. On January 20, 1997, BancGroup issued, through a
special purpose trust, $70 million of Trust Preferred Securities. See "BUSINESS
OF BANCGROUP -- Proposed Affiliate Banks."
 
     The following statements with respect to BancGroup Common Stock and
Preference Stock are brief summaries of material provisions of Delaware law, the
Restated Certificate of Incorporation (the "Certificate"), as amended, and
bylaws of BancGroup, do not purport to be complete and are qualified in their
entirety by reference to the foregoing.
 
BANCGROUP COMMON STOCK
 
     Dividends.  Subject to the rights of holders of BancGroup's Preference
Stock, if any, to receive certain dividends prior to the declaration of
dividends on shares of BancGroup Common Stock, when and as dividends, payable in
cash, stock or other property, are declared by the BancGroup Board of Directors,
the holders of BancGroup Common Stock are entitled to share ratably in such
dividends.
 
     Voting Rights.  Each holder of BancGroup Common Stock has one vote for each
share held on matters presented for consideration by the stockholders.
 
     Preemptive Rights.  The holders of BancGroup Common Stock have no
preemptive rights to acquire any additional shares of BancGroup.
 
                                       32
<PAGE>   40
 
     Issuance of Stock.  The BancGroup Certificate authorizes the BancGroup
Board to issue authorized shares of BancGroup Common Stock without stockholder
approval. However, BancGroup's Common Stock is listed on the NYSE, which
requires stockholder approval of the issuance of additional shares of BancGroup
Common Stock under certain circumstances.
 
     Liquidation Rights.  In the event of liquidation, dissolution or winding-up
of BancGroup, whether voluntary or involuntary, the holders of BancGroup Common
Stock will be entitled to share ratably in any of its assets or funds that are
available for distribution to its stockholders after the satisfaction of its
liabilities (or after adequate provision is made therefor) and after preferences
of any outstanding Preference Stock.
 
PREFERENCE STOCK
 
     BancGroup's Preference Stock may be issued from time to time as a class
without series, or if so determined by the BancGroup Board of Directors, either
in whole or in part in one or more series. The voting rights, and such
designations, preferences and relative, participating, optional or other special
rights, if any, and the qualifications, limitations or restrictions thereof, if
any, including, but not limited to, the dividend rights, conversion rights,
redemption rights and liquidation preferences, if any, of any wholly unissued
series of BancGroup Preference Stock (or of the entire class of BancGroup
Preference Stock if none of such shares has been issued), the number of shares
constituting any such series and the terms and conditions of the issue thereof
may be fixed by resolution of the BancGroup Board of Directors. BancGroup
Preference Stock may have a preference over the BancGroup Common Stock with
respect to the payment of dividends and the distribution of assets in the event
of the liquidation or winding-up of BancGroup and such other preferences as may
be fixed by the BancGroup Board.
 
1986 DEBENTURES
 
     BancGroup issued in 1986 its 7 1/2% Convertible Subordinated Debentures due
2011 (the "1986 Debentures") in the total principal amount of $28,750,000. The
1986 Debentures were issued under a trust indenture (the "1986 Indenture")
between BancGroup and SunTrust Bank, Atlanta, Georgia, as trustee.
 
     The 1986 Debentures will mature on March 31, 2011, and are convertible at
any time into shares of BancGroup Common Stock at the option of a holder
thereof, at the conversion price of $14 principal amount of the 1986 Debentures
for each share of BancGroup Common Stock. The conversion price is, however,
subject to adjustment upon the occurrence of certain events as described in the
1986 Indenture. In the event all of the outstanding 1986 Debentures are
converted into shares of BancGroup Common Stock in accordance with the 1986
Indenture, a total of 512,800 shares of such BancGroup Common Stock will be
issued. The 1986 Debentures are redeemable, in whole or in part, at the option
of BancGroup at certain premiums until 1996, when the redemption price shall be
equal to 100% of the face amount of the 1986 Debentures plus accrued interest.
The payment of principal and interest on the 1986 Debentures is subordinate, to
the extent provided in the 1986 Indenture, to the prior payment when due of all
Senior Indebtedness of BancGroup. "Senior Indebtedness" is defined as any
indebtedness of BancGroup for money borrowed, or any indebtedness incurred in
connection with an acquisition or with a merger or consolidation, outstanding on
the date of execution of the 1986 Indenture as originally executed, or
thereafter created, incurred or assumed, and any renewal, extension,
modification or refunding thereof, for the payment of which BancGroup (which
term does not include BancGroup's consolidated or unconsolidated subsidiaries)
is at the time of determination responsible or liable as obligor, guarantor or
otherwise. Senior Indebtedness does not include (i) indebtedness as to which, in
the instrument creating or evidencing the same or pursuant to which the same is
outstanding, it is provided that such indebtedness is subordinate in right of
payment to any other indebtedness of BancGroup, and (ii) indebtedness which by
its terms states that such indebtedness is subordinate to or equally subordinate
with the 1986 Debentures.
 
     At December 31, 1996, BancGroup's Senior Indebtedness as defined in the
1986 Indenture aggregated approximately $870 million. Such debt includes all
short-term debt consisting of federal funds purchased, securities purchased
under repurchase agreements and borrowings with the Federal Home Loan Bank but
excludes all federally-insured deposits. BancGroup may from time to time incur
additional indebtedness
 
                                       33
<PAGE>   41
 
constituting Senior Indebtedness. The 1986 Indenture does not limit the amount
of Senior Indebtedness which BancGroup may incur, nor does such indenture
prohibit BancGroup from creating liens on its property for any purpose.
 
     On January 29, 1997, BancGroup issued, through a special purpose trust, $70
million of Trust Preferred Securities in a private placement offering. The
securities bear interest at 8.92% and are mandatorily redeemable by BancGroup
beginning January 2017 through January 2027. Also, BancGroup has the option to
redeem the securities, in whole or in part, at a premium after January 2007
through January 2017, or at the face amount plus accrued interest after January
2017. The securities are subordinated to substantially all of BancGroup's
indebtedness. In BancGroup's consolidated statement of condition, these
securities will be shown as long-term debt.
 
CHANGES IN CONTROL
 
     Certain provisions of the BancGroup Certificate and bylaws may have the
effect of preventing, discouraging or delaying any change in control of
BancGroup. The authority of the BancGroup Board of Directors to issue BancGroup
Preference Stock with such rights and privileges, including voting rights, as it
may deem appropriate may enable the BancGroup Board to prevent a change in
control despite a shift in ownership of the BancGroup Common Stock. See
"General" and "Preference Stock." In addition, the power of BancGroup's Board to
issue additional shares of BancGroup Common Stock may help delay or deter a
change in control by increasing the number of shares needed to gain control. See
"BancGroup Common Stock." The following provisions also may deter any change in
control of BancGroup.
 
     Classified Board.  BancGroup's Board of Directors is classified into three
classes, as nearly equal in number as possible, with the members of each class
elected to three-year terms. Thus, one-third of BancGroup's Board of Directors
is elected by stockholders each year. With this provision, two annual elections
are required in order to change a majority of the Board of Directors. There are
currently 22 directors of BancGroup. This provision of BancGroup's Certificate
also stipulates that (i) directors can be removed only for cause upon a vote of
80% of the voting power of the outstanding shares entitled to vote in the
election of directors, voting as a class, (ii) vacancies in the Board may only
be filled by a majority vote of the directors remaining in office, (iii) the
maximum number of directors shall be fixed by resolution of the Board of
Directors, and (iv) the provisions relating to the classified Board can only be
amended by the affirmative vote of the holders of at least 80% of the voting
power of the outstanding shares entitled to vote in the election of directors,
voting as a class.
 
     Business Combinations.  Certain "Business Combinations" of BancGroup with a
"Related Person" may only be undertaken with the affirmative vote of at least
75% of the outstanding shares of "Voting Stock," plus the affirmative vote of at
least 67% of the outstanding shares of Voting Stock, not counting shares owned
by the Related Person, unless the Continuing Directors of BancGroup approve such
Business Combination. A "Related Person" is a person, or group, who owns or
acquires 10% or more of the outstanding shares of BancGroup Common Stock,
provided that no person shall be a Related Person if such person would have been
a Related Person on the date of approval of this provision by BancGroup's Board
of Directors, i.e., April 20, 1994. An effect of this provision may be to
exclude Robert E. Lowder, the current Chairman and President of BancGroup, and
certain members of his family from the definition of Related Person. A
"Continuing Director" is a director who was a member of the Board of Directors
immediately prior to the time a person became a Related Person. This provision
may not be amended without the affirmative vote of the holders of at least 75%
of the outstanding shares of Voting Stock, plus the affirmative vote of the
outstanding shares of at least 67% of the outstanding Voting Stock, excluding
shares held by a Related Person. This provision may have the effect of giving
the incumbent Board of Directors a veto over a merger or other Business
Combination that could be desired by a majority of BancGroup's stockholders. As
of March 1, 1997, the Board of Directors of BancGroup owned approximately 10.95%
of the outstanding shares of BancGroup Common Stock.
 
     Board Evaluation of Mergers.  BancGroup's Certificate permits the Board of
Directors to consider certain factors such as the character and financial
stability of the other party, the projected social, legal, and economic effects
of a proposed transaction upon the employees, suppliers, regulatory agencies and
customers and communities of BancGroup, and other factors when considering
whether BancGroup should undertake a
 
                                       34
<PAGE>   42
 
merger, sale of assets, or other similar transaction with another party. This
provision may not be amended except by the affirmative vote of at least 80% of
the outstanding shares of BancGroup Common Stock. This provision may give
greater latitude to the Board of Directors in terms of the factors which the
board may consider in recommending or rejecting a merger or other Business
Combination of BancGroup.
 
     Director Authority.  BancGroup's Certificate prohibits stockholders from
calling special stockholders' meetings and acting by written consent. It also
provides that only BancGroup's Board of Directors has the authority to undertake
certain actions with respect to governing BancGroup such as appointing
committees, electing officers, and establishing compensation of officers, and it
allows the Board to act by majority vote.
 
     Bylaw Provisions.  BancGroup's bylaws provide that stockholders wishing to
propose nominees for the Board of Directors or other business to be taken up at
an annual meeting of BancGroup stockholders must comply with certain advance
written notice provisions. These bylaw provisions are intended to provide for
the more orderly conduct of stockholder meetings but could make it more
difficult for stockholders to nominate directors or introduce business at
stockholder meetings.
 
     Delaware Business Combination Statute.  Subject to some exceptions,
Delaware law prohibits BancGroup from entering into certain "business
combinations" (as defined) involving persons beneficially owning 15% or more of
the outstanding BancGroup Common Stock (or who is an affiliate of BancGroup and
has over the past three years beneficially owned 15% or more of such stock)
(either, for the purpose of this paragraph, an "Interested Stockholder"), unless
the BancGroup Board has approved either (i) the business combination or (ii)
prior to the stock acquisition by which such person's beneficial ownership
interest reached 15% (a "Stock Acquisition"), the Stock Acquisition. The
prohibition lasts for three years from the date of the Stock Acquisition.
Notwithstanding the preceding, Delaware law allows BancGroup to enter into a
business combination with an Interested Stockholder if (i) the business
combination is approved by the BancGroup Board of Directors and authorized by an
affirmative vote of at least 66 2/3% of the outstanding voting stock of
BancGroup which is not owned by the Interested Stockholder or (ii) upon
consummation of the transaction which resulted in the stockholder becoming an
Interested Stockholder, such stockholder owned at least 85% of the outstanding
stock of BancGroup (excluding BancGroup stock held by officers and directors of
BancGroup or by certain BancGroup stock plans). These provisions of Delaware law
apply simultaneously with the provisions of BancGroup's Certificate relating to
business combinations with a related person, described above at "Business
Combinations," but they are generally less restrictive than BancGroup's
Certificate.
 
     Control Acquisitions.  As it relates to BancGroup, the Change in Bank
Control Act of 1978 prohibits a person or group of persons from acquiring
"control" of a bank holding company unless the Federal Reserve has been given 60
days' prior written notice of such proposed acquisition and within that time
period the Federal Reserve has not issued a notice disapproving the proposed
acquisition or extending for up to another 30 days the period during which such
a disapproval may be issued. An acquisition may be made prior to the expiration
of the disapproval period if the Federal Reserve issues written notice of its
intent not to disapprove the action. Under a rebuttable presumption established
by the Federal Reserve, the acquisition of more than 10% of a class of voting
stock of a bank holding company with a class of securities registered under
Section 12 of the Exchange Act, such as BancGroup, would, under the
circumstances set forth in the presumption, constitute the acquisition of
control. The receipt of revocable proxies, provided the proxies terminate within
a reasonable time after the meeting to which they relate, is not included in
determining percentages for change in control purposes.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
     If the Merger is consummated, shareholders of First Commerce (except those
perfecting dissenters' rights) will become holders of BancGroup Common Stock.
The rights of the holders of the First Commerce Common Stock who become holders
of the BancGroup Common Stock following the Merger will be governed by
BancGroup's Certificate and bylaws, as well as the laws of Delaware, the state
in which BancGroup is incorporated.
 
     The following summary compares the rights of the shareholders of First
Commerce Common Stock with the rights of the holders of the BancGroup Common
Stock. For a more complete description of the rights of the holders of BancGroup
Common Stock, see "BANCGROUP CAPITAL STOCK AND DEBENTURES."
 
     The following information is qualified in its entirety by BancGroup's
Certificate and bylaws, and First Commerce's Restated Articles of Incorporation
and bylaws, the Delaware General Corporation Law (the "Delaware GCL") and the
Florida Business Corporation Act ("FBCA").
 
DIRECTOR ELECTIONS
 
     First Commerce.  First Commerce's directors are elected annually.
Shareholders may not cumulate votes in connection with such election (nor for
any other purpose).
 
     BancGroup.  BancGroup's directors are elected to terms of three years with
approximately one-third of the Board to be elected annually. There is no
cumulative voting in the election of directors. See "BANCGROUP CAPITAL STOCK AND
DEBENTURES -- Changes in Control -- Classified Board."
 
REMOVAL OF DIRECTORS
 
     First Commerce.  First Commerce's Restated Articles of Incorporation
provide that directors may be removed by shareholders only for cause.
 
     BancGroup.  The BancGroup Certificate provides that a director may be
removed from office, but only for cause and by the affirmative vote of the
holders of at least 80% of the voting shares then entitled to vote at an
election of directors.
 
VOTING
 
     First Commerce.  Each holder of First Commerce Common Stock is entitled to
cast one vote for each share held on each issue with respect to which a
shareholder vote is authorized, but may not cumulate votes for the election of
directors or for any other purpose.
 
     BancGroup.  Each stockholder of BancGroup is entitled to one vote for each
share of BancGroup Common Stock held, and such holders are not entitled to
cumulative voting rights in the election of directors.
 
PREEMPTIVE RIGHTS
 
     First Commerce.  Holders of First Commerce Common Stock have no preemptive
rights to subscribe for additional shares on a pro rata or other basis when and
if shares are offered for sale by First Commerce.
 
     BancGroup.  The holders of BancGroup Common Stock have no preemptive rights
to acquire any additional shares of BancGroup Common Stock or any other shares
of BancGroup capital stock.
 
DIRECTORS' LIABILITY
 
     First Commerce.  Section 607.0831 of the FBCA provides that a director of
First Commerce will not be personally liable for monetary damages to First
Commerce or any other person for any statement, vote, decision or failure to
act, regarding corporate management or policy, by a director unless: (a) the
director breached or failed to perform his duties as a director, and (b) the
director's breach of or failure to perform those duties constitutes: (1) a
violation of the criminal law, unless the director had reasonable cause to
believe
 
                                       36
<PAGE>   44
 
his conduct was lawful or had no reasonable cause to believe his conduct was
unlawful, (2) a transaction in which the director derived an improper personal
benefit, (3) a payment of certain unlawful dividends and distributions, (4) in a
proceeding by or in the right of First Commerce to procure judgment in its favor
or by or in the right of a shareholder, conscious disregard for the best
interests of First Commerce, or willful misconduct, or (5) in a proceeding by or
in the right of someone other than First Commerce or a shareholder, recklessness
or an act or omission which was committed in bad faith or with malicious purpose
or in a manner exhibiting wanton and willful disregard of human rights, safety
or property. This provision would absolve directors of First Commerce of
personal liability for negligence in the performance of their duties, including
gross negligence. It would not permit a director to be exculpated, however, from
liability for actions involving conflicts of interest or breaches of the
traditional "duty of loyalty" to First Commerce and its shareholders, and it
would not affect the availability of injunctive and other equitable relief as a
remedy.
 
     BancGroup.  The BancGroup Certificate provides that a director of BancGroup
will have no personal liability to BancGroup or its stockholders for monetary
damages for breach of fiduciary duty as a director except (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (iii) for the payment of certain unlawful dividends
and the making of certain stock purchases or redemptions, or (iv) for any
transaction from which the director derived an improper personal benefit. This
provision would absolve directors of personal liability for negligence in the
performance of duties, including gross negligence. It would not permit a
director to be exculpated, however, for liability for actions involving
conflicts of interest or breaches of the traditional "duty of loyalty" to
BancGroup and its stockholders, and it would not affect the availability of
injunctive or other equitable relief as a remedy.
 
INDEMNIFICATION
 
     First Commerce.  Under Section 607.0850 of the FBCA, the directors and
officers of First Commerce may be indemnified against certain liabilities which
they may incur in their capacity as officers and directors. Such indemnification
is generally available if the executive acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interest of
First Commerce, and with respect to any criminal proceeding, had no reasonable
cause to believe his or her conduct was unlawful. Indemnification may also be
available unless a court of competent jurisdiction establishes by final
adjudication that the actions or omissions of the executive are material to the
cause of action so adjudicated and constituted: (a) a violation of the criminal
law, unless the executive had reasonable cause to believe his or her conduct was
lawful or had no reasonable cause to believe his or her conduct was unlawful;
(b) a transaction from which the executive derived an improper personal benefit;
or (c) willful misconduct or conscious disregard for the best interest of First
Commerce in a proceeding by or in the right of First Commerce to procure a
judgment in its favor or in a proceeding by or in the right of a shareholder.
First Commerce's Bylaws require First Commerce to indemnify its officers and
directors to the full extent permitted by the statute. Further, to the extent
that the proposed indemnitee is successful on the merits or otherwise in the
defense of any action, suit or proceeding (or any claim, issue or matter
therein) he or she must be indemnified against expenses (including attorney's
fees) actually and reasonably incurred by him or her in connection with such
proceeding.
 
     First Commerce maintains a directors' and officers' insurance policy
pursuant to which officers and directors of First Commerce would be entitled to
indemnification against certain liabilities, including reimbursement of certain
expenses.
 
     BancGroup.  Section 145 of the Delaware GCL contains detailed and
comprehensive provisions providing for indemnification of directors and officers
of Delaware corporations against expenses, judgments, fines and settlements in
connection with litigation. Under the Delaware GCL, other than an action brought
by or in the right of BancGroup, such indemnification is available if it is
determined that the proposed indemnitee acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interests of
BancGroup and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. In actions brought by or
in the right of BancGroup, such indemnification is limited to expenses
(including attorneys' fees) actually and reasonably incurred in the defense or
settlement of such action if the indemnitee acted in good faith and in a manner
he or she reasonably believed to be in or not
 
                                       37
<PAGE>   45
 
opposed to the best interests of BancGroup and except that no indemnification
shall be made in respect of any claim, issue or matter as to which such person
has been adjudged to be liable to BancGroup unless and only to the extent that
the Delaware Court of Chancery or the court in which the action was brought
determines upon application that in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses as
the court deems proper.
 
     To the extent that the proposed indemnitee has been successful on the
merits or otherwise in defense of any action, suit or proceeding (or any claim,
issue or matter therein), he or she must be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.
 
     BancGroup maintains an officers' and directors' insurance policy and a
separate indemnification agreement pursuant to which officers and directors of
BancGroup would be entitled to indemnification against certain liabilities,
including reimbursement of certain expenses that extends beyond the minimum
indemnification provided by Section 145 of the Delaware GCL.
 
SPECIAL MEETINGS OF STOCKHOLDERS; ACTION WITHOUT A MEETING
 
     First Commerce.  First Commerce's bylaws authorize a special shareholder
meeting to be called by the board of directors, the chairman of the board, First
Commerce's president, or by the holders of not less than twenty-five percent of
the total voting power of all outstanding shares of voting stock.
 
     Pursuant to section 607.0704 of the FBCA, the First Commerce Restated
Articles of Incorporation provide that any action required or permitted by the
FBCA to be taken by shareholders of First Commerce may be taken only at an
annual or special meeting of shareholders, and may not be taken by written
consent.
 
     BancGroup.  Under the BancGroup Certificate, a special meeting of
BancGroup's stockholders may only be called by a majority of the BancGroup Board
of Directors or by the chairman of the Board of Directors of BancGroup. Holders
of BancGroup Common Stock may not call special meetings or act by written
consent.
 
MERGERS, SHARE EXCHANGES AND SALES OF ASSETS
 
     First Commerce.  The FBCA provides that mergers and sales of substantially
all of the property of a Florida corporation must be approved by a majority of
the outstanding shares of the corporation entitled to vote thereon. The FBCA
also provides, however, that the shareholders of a corporation surviving a
merger need not approve the transaction if: (a) the articles of incorporation of
the surviving corporation will not differ from its articles before the merger,
and (b) each shareholder of the surviving corporation whose shares were
outstanding immediately prior to the effective date of the merger will hold the
same number of shares with identical designations, preferences, limitations and
relative rights, immediately after the merger.
 
     BancGroup.  The Delaware GCL provides that mergers and sales of
substantially all of the assets of Delaware corporations must be approved by a
majority of the outstanding stock of the corporation entitled to vote thereon.
The Delaware GCL also provides, however, that the stockholders of the
corporation surviving a merger need not approve the transaction if: (i) the
agreement of merger does not amend in any respect the certificate of
incorporation of such corporation; (ii) each share of stock of such corporation
outstanding immediately prior to the effective date of the merger is to be an
identical outstanding or treasury share of the surviving corporation after the
effective date of the merger; and (iii) either no shares of common stock of the
surviving corporation and no shares, securities or obligations convertible into
such stock are to be issued or delivered under the plan of merger, or the
authorized unissued shares or the treasury shares of common stock of the
surviving corporation to be issued or delivered under the plan of merger plus
those initially issuable upon conversion of any other shares, securities or
obligations to be issued or delivered under such plan do not exceed 20% of the
shares of common stock of such corporation outstanding immediately prior to the
effective date of the merger. See also "BANCGROUP CAPITAL STOCK AND
DEBENTURES -- Changes in Control" for a description of the statutory provisions
and the provisions of the BancGroup Certificate relating to changes of control
of BancGroup. See "Antitakeover Statutes" for a description of additional
restrictions on business combination transactions.

<PAGE>   46
 
AMENDMENT OF CERTIFICATE OF INCORPORATION AND BYLAWS
 
     First Commerce.  Section 607.1002 of the FBCA permits the Board of
Directors to amend the Restated Articles of Incorporation in certain minor
respects without stockholder action, but Section 607.1003 requires most
amendments to be adopted by the stockholders upon recommendation of the Board of
Directors. Unless the FBCA requires a greater vote, amendments may be adopted by
a majority of the votes cast, a quorum being present.
 
     Section 607.1020 of the FBCA permits the Board of Directors to amend or
repeal the bylaws unless the FBCA or the stockholders provide otherwise. The
stockholders entitled to vote have concurrent power to amend or repeal the
bylaws.
 
     BancGroup.  Under the Delaware GCL, a Delaware corporation's certificate of
incorporation may be amended by the affirmative vote of the holders of a
majority of the outstanding shares entitled to vote thereon, and a majority of
the outstanding stock of each class entitled to vote as a class, unless the
certificate requires the vote of a larger portion of the stock. The BancGroup
Certificate requires "supermajority" stockholder approval to amend or repeal any
provision of, or adopt any provision inconsistent with, certain provisions in
the BancGroup Certificate governing (i) the election or removal of directors,
(ii) business combinations between BancGroup and a Related Person, and (iii)
board of directors evaluation of business combination procedures. See "BANCGROUP
CAPITAL STOCK AND DEBENTURES -- Changes in Control."
 
     As is permitted by the Delaware GCL, the Certificate gives the Board of
Directors the power to adopt, amend or repeal the bylaws. The stockholders
entitled to vote have concurrent power to adopt, amend or repeal the BancGroup
bylaws.
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
     First Commerce.  Holders of First Commerce Common Stock as of the Record
Date are entitled to dissenters' rights of appraisal under Florida law. For a
description of such appraisal rights, see "THE MERGER -- Rights of Dissenting
Stockholders."
 
     BancGroup.  Under the Delaware GCL, a stockholder has the right, in certain
circumstances, to dissent from certain corporate transactions and receive the
fair value of his or her shares in cash in lieu of the consideration he or she
otherwise would have received in the transaction. For this purpose, "fair value"
may be determined by all generally accepted techniques of valuation used in the
financial community, excluding any element of value arising from the
accomplishment or expectation of the transaction, but including elements of
future value that are known or susceptible of proof. Such fair value is
determined by the Delaware Court of Chancery if a petition for appraisal is
timely filed. Appraisal rights are not available, however, to stockholders of a
corporation (i) if the shares are listed on a national securities exchange (as
is BancGroup Common Stock) or quoted on the NASDAQ National Market System, or
held of record by more than 2,000 stockholders (as is BancGroup Common Stock),
and (ii) stockholders are permitted by the terms of the merger or consolidation
to accept in exchange for their shares (a) shares of stock of the surviving or
resulting corporation, (b) shares of stock of another corporation listed on a
national securities exchange or held of record by more than 2,000 stockholders,
(c) cash in lieu of fractional shares of such stock, or (d) any combination
thereof. Stockholders are not permitted appraisal rights in a merger if such
corporation is the surviving corporation and no vote of its stockholders is
required.
 
PREFERRED STOCK
 
     First Commerce.  First Commerce's Restated Articles of Incorporation
authorize the issuance of 3,000,000 shares of Preferred Stock from time to time
by resolution of the First Commerce Board of Directors. Currently, no shares of
Preferred Stock are issued and outstanding.
 
     BancGroup.  The BancGroup Certificate authorizes the issuance of 1,000,000
shares of Preference Stock from time to time by resolution of the BancGroup
Board of Directors. Currently, no shares of Preference Stock are issued and
outstanding. See "BANCGROUP CAPITAL STOCK AND DEBENTURES -- Preference Stock."
 
                                       39
<PAGE>   47
 
EFFECT OF THE MERGER ON FIRST COMMERCE SHAREHOLDERS
 
     As of             , 1997, First Commerce had           shareholders of
record and           outstanding shares of First Commerce Common Stock. As of
March 1, 1997, BancGroup had 38,955,210 shares of BancGroup Common Stock
outstanding with 7,129 stockholders of record.
 
     Assuming that no dissenters' rights of appraisal are exercised in the
Merger, no First Commerce Options are exercised prior to the Merger, and a
Market Value of BancGroup Common Stock not less than $19.35 and no more than
$25.16, an aggregate amount of           shares of BancGroup Common Stock would
be issued to the shareholders of First Commerce pursuant to the Merger. These
shares would represent approximately      % of the total shares of BancGroup
Common Stock outstanding after the Merger, not counting any shares of BancGroup
Common Stock to be issued in other pending acquisitions. BancGroup anticipates
that the shares of BancGroup Common Stock to be issued in the Merger will come
from shares repurchased by BancGroup in the open market.
 
     The issuance of the BancGroup Common Stock pursuant to the Merger will not
reduce the percentage interest of the BancGroup Common Stock currently held by
each principal stockholder and each director and officer of BancGroup if
BancGroup repurchases in the open market all shares to be issued in the Merger.
Based upon the foregoing assumption, a group, the directors and officers of
BancGroup would own approximately 10.98% of BancGroup's outstanding shares after
the Merger. See "BUSINESS OF BANCGROUP -- Voting Securities and Principal
Stockholders."
 
     BancGroup has entered into agreements pursuant to which additional shares
of BancGroup Common Stock will be issued. See "BUSINESS OF BANCGROUP -- Proposed
Affiliate Banks."

                  SELECTED FINANCIAL AND OPERATING INFORMATION
 
     The following tables present certain financial information for BancGroup on
a historical basis (as restated) for the years ended December 31, 1996, 1995,

years ended December 31, 1996, 1995, 1994, 1993 and 1992 and as of December 31,
1996.
 
     The pro forma information includes consolidated BancGroup and subsidiaries
(as restated) and consolidated Great Southern, Tomoka, Fort Brooke, First
Commerce, Shamrock and First Family. The pro forma balance sheet data gives
effect to the combinations as if they had occurred on December 31, 1996 and the
pro forma operating data gives effect to the combinations as if they had
occurred at the beginning of the earliest period presented. Note that for the
purchase method combinations, Article 11 of Regulation S-X requires pro forma
statements be presented for only the most recent fiscal year. Accordingly, only

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
FSB/OSCEOLA SALE AND FSB/CBC MERGER
 
  Sale of FSB/Osceola
 
     On May 1, 1995, First Commerce sold the 240,000 shares of common stock of
First Sterling Bank of Osceola County ("FSB/Osceola") (which constituted 80% of
the outstanding shares of FSB/Osceola stock) owned by First Commerce to certain
unaffiliated individuals for $1.8 million in cash. See "--Sale of FSB/Osceola."
Accordingly, FSB/Osceola's results of operations for the four months ended April
30, 1995 are included in First Commerce's 1995 consolidated financial statements
and operating results for 1995 in "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
  FSB/CBC Merger
 
     On August 31, 1995, Commerce Bank Corporation ("CBC") merged with and into
First Sterling Bancshares, Inc. ("FSB") (the "FSB/CBC Merger") and FSB changed
its name to First Commerce Banks of Florida, Inc. In the FSB/CBC Merger, the
outstanding shares of CBC common stock were converted into an aggregate of
746,704 shares of FSB common stock, par value $.01 per share, and $1,000 of cash
in lieu of fractional shares. Upon consummation of the FSB/CBC Merger, Commerce
Bank of Central Florida (a subsidiary of CBC) merged with and into First
Sterling Bank (a subsidiary of FSB), which changed its name to First Commerce
Bank of Polk County ("the Bank"). First Commerce's principal asset is its
ownership of 99.7% of the voting shares of the Bank. The First Commerce/CBC
Merger has been accounted for as a pooling of interests and, accordingly,
amounts presented in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" have been combined to include financial
information for both FSB and CBC.
 
GENERAL
 
     First Commerce's results of operations are primarily dependent upon the
results of operations of the Bank. The Bank conducts commercial banking business
consisting of attracting deposits from the general public and applying those
funds to the origination of commercial, consumer and real estate loans
(including commercial loans collateralized by real estate). The Bank's
profitability depends primarily on net interest income, which is the excess of
interest income generated from interest-earning assets (i.e., loans, investments
and federal funds sold) over interest expense incurred on interest-bearing
liabilities (i.e., customer deposits and borrowed funds). Net interest income is
affected by the relative amounts of interest-earning assets and interest-bearing
liabilities, and the interest rate earned and paid on these balances. Net
interest income is dependent upon The Bank's interest-rate spread which is the
excess of average yield earned on its interest-earning assets over the average
rate paid on its interest-bearing liabilities. When interest-earning assets
approximate or exceed interest-bearing liabilities, any positive interest rate
spread will generate net interest income. The interest-rate spread is impacted
by interest rates and the amounts of deposits and loans. Additionally, the
Bank's profitability is affected by such factors as the level of non-interest
income and expenses, the provision for credit losses, and the effective tax
rate. Non-interest income consists primarily of service fees on deposit accounts
and income from the sale of loans and investment securities. Non-interest
expense consists primarily of compensation and employee benefits, occupancy and
equipment expenses, professional fees, data processing costs, deposit insurance
premiums paid to the FDIC, and other operating expenses.
 
     Management's discussion and analysis of earnings and related financial data
are presented herein to assist investors in understanding the financial
condition of First Commerce at, and the results of operations of First Commerce
for the years ended, December 31, 1996 and 1995. This discussion should be read
in conjunction with the consolidated financial statements and related footnotes
of First Commerce presented elsewhere herein.

LIQUIDITY
 
  First Commerce
 
     First Commerce is a legal business entity separate and distinct from the
Bank. First Commerce's principal source of cash flow during 1996 was interest
income on its portfolio of loans purchased from FSB/Osceola and cash on deposit
($887,000 as of December 31, 1996) with the Bank, which totaled $108,000 during
the year ended December 31, 1996. Possible future sources of cash flow for First
Commerce include dividends or management fees from the Bank. However, there are
various statutory limitations on the ability of the Bank to pay dividends,
extend credit, or otherwise supply funds to First Commerce. The FDIC and the
Florida Department also have the general authority to limit the dividends paid
by insured banks and bank holding companies. First Commerce has not paid any
cash dividends to its shareholders.
 
     During the year ended December 31, 1996, First Commerce's cash and cash
equivalents increased $3.1 million, to $13.5 million as of December 31, 1996
from $10.4 million as of December 31, 1995. During 1996, investing activities
provided $8.9 million of cash, and financing activities used $7.2 million of
cash. First Commerce's total assets decreased $7.1 million to $106 million at
December 31, 1996 from $113.1 million at December 31, 1995.
 
  The Bank
 
     Liquidity management involves the ability to meet the cash flow
requirements of customers who may be depositors wanting to withdraw their funds
or borrowers needing assurance that sufficient funds will be available to meet
their credit needs. In the ordinary course of business, the Bank's cash flows
are generated from interest and fee income, as well as from loan repayments and
the maturity of investment securities held-to-maturity. In addition to cash and
due from banks, the Bank considers all securities available-for-sale and federal
funds sold as primary sources of asset liquidity. Many factors affect the
ability to accomplish these liquidity objectives successfully, including the
economic environment, and the asset/liability mix within the balance sheet, as
well as the Bank's reputation in the community. At December 31, 1996, the Bank
had commitments to originate loans totaling $2.8 million. In addition, scheduled
maturities of certificates of deposit during 1997 totaled $31.3 million.
Management believes that the Bank has adequate resources to fund all of its
commitments, that substantially all of its existing commitments will be funded
within 12 months and, if so desired, that the Bank can adjust the rates and
terms on certificates of deposit and other deposit accounts to retain deposits
in a changing interest rate environment.
 
     A state-chartered commercial bank is required to maintain a liquidity
reserve of at least 15% of its transaction deposit accounts and 8% of its
non-transaction deposit accounts. The liquidity reserve may consist of cash on
hand, cash on demand deposit with other correspondent banks, and other
investments and short-term marketable securities as determined by the rules of
the Florida Department, such as federal funds sold and United States securities
or securities guaranteed by the United States. As of December 31, 1996, the Bank
had a liquidity ratio of 36.01%.
 
CAPITAL RESOURCES
 
     First Commerce's total stockholders' equity was $10.6 million and $10.5
million as of December 31, 1996 and 1995, respectively, which represents an
increase of $100,000. This increase was the result of 1996's net income of
$138,000 offset by the $46,000 change in the unrealized securities losses at
December 31, 1996 from December 31, 1995. First Commerce's total stockholders'
equity was 10.0% and 9.30% of total assets as of December 31, 1996 and 1995,
respectively. The Bank's total stockholders' equity was $9.4 million and $8.5
million as of December 31, 1996 and 1995, respectively, or an increase of
$900,000. This increase was the result of the purchase of $750,000 of the Bank's
common stock by First Commerce plus the Bank's 1996 net income of $239,000 less
the $46,000 change in the unrealized securities losses at December 31, 1996 from
December 31, 1995.
 
     The federal banking regulatory authorities have adopted certain "prompt
corrective action" rules with respect to depository institutions. The rules
establish five capital tiers: "well capitalized," "adequately
 
                                       56
<PAGE>   64
 
capitalized," "undercapitalized," "significantly undercapitalized," and
"critically undercapitalized." The various federal banking regulatory agencies
have adopted regulations to implement the capital rules by, among other things,
defining the relevant capital measures for the five capital categories. An
institution is deemed to be "well capitalized" if it has a total risk-based
capital ratio of 10% or greater, a Tier 1 risk-based capital ratio of 6% or
greater, and a Tier 1 leverage ratio of 5% or greater and is not subject to a
regulatory order, agreement, or directive to meet and maintain a specific
capital level. At December 31, 1996, the Bank met the capital ratios of a "well
capitalized" financial institution with a total risk-based capital ratio of
13.43%, a Tier 1 risk-based capital ratio of 11.66%, and a Tier 1 leverage ratio
of 9.37%. Depository institutions which fall below the "adequately capitalized"
category generally are prohibited from making any capital distribution, are
subject to growth limitations, and are required to submit a capital restoration
plan. There are a number of requirements and restrictions that may be imposed on
institutions treated as "significantly undercapitalized" and, if the institution
is "critically undercapitalized," the banking regulatory agencies have the right
to appoint a receiver or conservator.
 
     In accordance with risk capital guidelines issued by the FDIC, the Bank is
required to maintain a minimum standard of total capital to risk-weighted assets
of 8%. Additionally, the FDIC requires banks to maintain a minimum
leverage-capital ratio of Tier 1 capital (as defined) to total assets. The
leverage-capital ratio ranges from 3% to 5% based on the bank's rating under the
regulatory rating system. The required leverage-capital ratio for the Bank at
December 31, 1996 was 4%. The following table summarizes the regulatory capital
levels and ratios for the Bank:

  Net interest income
 
     Net interest income, which constitutes the principal source of income for
First Commerce, represents the excess of interest income on interest-earning
assets over interest expense on interest-bearing liabilities. The principal
interest-earning assets are federal funds sold, investment securities and loans
receivable. Interest-bearing liabilities primarily consist of time deposits,
interest-bearing checking accounts ("NOW accounts"), savings deposits and money
market accounts. Funds attracted by these interest-bearing liabilities are
invested in interest-earning assets. Accordingly, net interest income depends
upon the volume of average interest-earning assets and average interest-bearing
liabilities and the interest rates earned or paid on them.

(1) Yields on tax-free investments are computed on a tax equivalent basis using
    a 37.3% effective income tax rate.
 
     First Commerce's net interest income was $5.4 million for the year ended
December 31, 1996 compared with $5.6 million for the year ended December 31,
1995, or a decrease of $200,000 or 3.6%. This decrease in net interest income
resulted from a shrinkage in earning assets of $8.4 million. Throughout 1996,
management allowed high priced deposit accounts to leave the Bank and this
shrinkage in deposits was funded with cash flow from loan payoffs and repayments
of mortgage backed securities. For a discussion of the purchase of loans from
FSB/Osceola, see "-- Sale of FSB/Osceola." The 15% volume decrease in 1996 from
1995 in interest expense was primarily attributable to the 11% decrease in
average interest-bearing liabilities. The yield on total investments and Federal
Funds sold decreased 122 basis points reflecting a general decrease in the rate
paid on Federal Funds sold and the above normal repayment amounts on mortgage
backed securities in the months of February, April, May and June of 1996. The
interest rate paid on interest bearing liabilities decreased 12 basis points
primarily due to a reduced amount of deposits as a result of management's policy
to reprice the Bank's deposits at lower rates. The overall result was an
increase in the net interest margin to 5.32% during 1996 from 5.16% during 1995.
 
  Provision for Credit Losses
 
     The provision for credit losses is charged to earnings to bring the

conducted by First Commerce, the amounts of non-performing loans, general
economic conditions, particularly as they relate to First Commerce's market
area, and other factors related to the collectibility of First Commerce's loan
portfolio. During the year ended December 31, 1996, the provision for credit
losses was $974,000, as compared to $1.2 million during the year ended December
31, 1995, or a decrease of $226,000. While the provision for credit losses
decreased, the allowance for credit losses increased to $1.5 million at December
31, 1996 from $1.2 million at December 31, 1995, or an increase of $300,000. The
increased allowance for credit losses was primarily in recognition of an
increase in non-performing loans to $2.6 million as of December 31, 1996 from
$1.6 million as of December 31, 1995. See "-- General," "-- Financial
Condition -- Classification of Assets," and "-- Financial Condition -- Allowance
for Credit Losses." As of December 31, 1996 and 1995, the allowance for credit
losses was 2.14% and 1.67%, respectively, of total loans receivable, and was
55.88% and 74.69%, respectively, of non-performing loans.
 
  Other Income
 
     Other income is primarily composed of deposit service charges and fees and
gains on sales of certain assets. During the year ended December 31, 1996, other
income decreased to $923,000 from $1.6 million during the year ended December
31, 1995, or a decrease of $677,000 or 43%. This decrease was primarily due to
First Commerce recognizing two, non-recurring events in 1995. On May 1, 1995,
First Commerce sold its stock ownership in FSB/Osceola, recognizing a gain on
the sale of $564,000 and First Commerce recognized a previously deferred gain of
$171,000 which had resulted from the sale of bank property by FSB to FSB/Osceola
prior to 1995.
 
     During the year ended December 31, 1996, deposit service charges and fees
decreased to $855,000 from $917,000 during the year ended December 31, 1995, or
a decrease of $62,000 or 6.8%. This decrease was primarily attributable to the
decrease in service chargeable accounts resulting from the sale of the
subsidiary bank, First Commerce/Osceola in May of 1995 and the reduction of
higher priced deposit accounts in 1996.
 
  Other Expenses
 
     During the year ended December 31, 1996, other expenses increased to $5.2
million from $5.0 million during the year ended December 31, 1995, or an
increase of $200,000 or 3.85%. The following narrative sets forth additional
information on certain other expense categories which had significant changes.
 
     During the year ended December 31, 1996, compensation and benefits
increased to $2.47 million from $2.15 million during the year ended December 31,
1995, or an increase of $320,000 or 14.9%. This increase was primarily due to an
increase in the number of employees at the Bank and annual compensation and
benefit increases for existing employees.
 
     Professional fees increased to $446,000 during 1996, from $428,000 during
1995, or an increase of $18,000 or 4.2%. This increase resulted primarily from
the increased professional fees associated with the planned mergers with two
unaffiliated banks during 1996 (which mergers were terminated in August 1996)
and fees in 1996 associated with collection costs of non-performing loans.
 
     Other real estate owned expenses decreased to $77,000 during 1996, from
$175,000 during 1995, or a decrease of $98,000 or 56%. This decrease primarily
resulted from a decrease in the amount of acquired real estate held for sale,
going to $79,000 in 1996 from $301,000 in 1995. Certain OREO properties, carried
forward into 1996, have been written down to carrying values in 1996.
 
     Advertising and promotion expense decreased to $90,000 during 1996, from
$163,000 during 1995, a decrease of $73,000 or 44.8%. This decrease resulted
primarily from one-time expenses in 1995 related to the FSB/CBC merger.
 
     FDIC insurance expense decreased to $123,000 during 1996, from $140,000
during 1995, a decrease of $17,000 or 12%. This decrease resulted primarily from
two factors: (i) the FDIC's reduction in insurance premiums; and (ii) a refund
of the 4th Quarter Assessment of $10,000 due to the recapitalization of the SAIF
Insurance fund.
 
                                       61

     Stationery expense increased to $163,000 during 1996, from $121,000 during
1995, or an increase of $42,000 or 34.7%. This increase resulted primarily from
printing expenses associated with the FSB/CBC merger.
 
     Other expenses decreased to $617,000 during 1996, from $673,000 during
1995, or a decrease of $56,000 or 8.3%. This decrease resulted primarily from
decreased business development expenses, HONOR expense, telephone expense,
consultant fees, courier service, property and casualty insurance and check
printing charges.
 
  Taxes on Income
 
     During the years ended December 31, 1996 and 1995, First Commerce recorded
taxes on income of $15,000 and $497,000, respectively, reflecting effective
income tax rates of 9.74% in 1996 and 47.33% in 1995. The decrease in the
effective income tax rate during 1996 was primarily due to income tax refunds
received in 1996 for the 1995 tax year which were more than the amount recorded
at December 31, 1995.
 
SALE OF FSB/OSCEOLA
 
     On May 1, 1995, First Commerce sold its 80% ownership interest in
FSB/Osceola to certain unaffiliated individuals for $1.8 million in cash. See
"Business of First Commerce -- FSB/Osceola Sale." At April 30, 1995, FSB/Osceola
had total assets of $16.4 million, total liabilities of $14.8 million, and
stockholders' equity of $1.6 million as summarized below:

ASSET/LIABILITY MANAGEMENT
 
     A principal objective of First Commerce's asset/liability management
strategy is to minimize its exposure to changes in interest rates by matching
the maturity and repricing horizons of interest-earning assets and
interest-bearing liabilities. This strategy is overseen in part through the
direction of the Bank's Asset and Liability Committee (the "ALCO Committee")
which establishes policies and monitors results to control interest rate
sensitivity.
 
     Management evaluates interest rate risk and then formulates guidelines
regarding asset generation and repricing, funding sources and pricing, and
off-balance sheet commitments in order to maintain interest rate risk within
target levels for the appropriate level of risk which are determined by the ALCO
Committee. The ALCO Committee uses computer models prepared by a third party to
measure the Bank's interest-rate sensitivity. From these reports, the ALCO
Committee can estimate the net interest income effect of various interest-rate
scenarios.
 
     As a part of First Commerce's interest-rate risk management policy, the
ALCO Committee examines the extent to which its assets and liabilities are
"interest-rate sensitive" and monitors the Bank's interest-rate sensitivity
"gap." An asset or liability is considered to be interest-rate sensitive if it
will reprice or mature within the time period analyzed, usually one year or
less. The interest-rate sensitivity gap is the difference between
interest-earning assets and interest-bearing liabilities scheduled to mature or
reprice within such time period. A gap is considered positive when the amount of
interest-rate sensitive assets exceeds the amount of interest-rate sensitive
liabilities. A gap is considered negative when the amount of interest-rate
sensitive liabilities exceeds interest-rate sensitive assets. During a period 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 a period of falling interest rates, a negative gap would
tend to result in an increase in net interest income, while a positive gap would
tend to adversely affect net interest income. In addition, any premiums on
mortgage-backed securities are amortized to interest income based on the
estimated remaining life of the related securities. Management periodically
reviews the remaining estimated life of mortgage-backed securities, and adjusts
the amortization of the premiums accordingly, in light of changes in market
interest rates and other factors affecting prepayment rates on the underlying
mortgages. Acceleration of the amortization of premiums on mortgage-backed
securities reduces the effective yield on these investments and, accordingly,
adversely affects net interest income. As of December 31, 1996, the remaining
unamortized premiums on mortgage-backed securities totaled $286,000. See
"-- Financial Condition -- Investment Securities."
 
     The ALCO Committee's policy is to maintain a cumulative one-year gap which
falls in the range of (20%) to 20% of total assets. As of December 31, 1996,
First Commerce's cumulative one-year gap was a positive 17% of total assets.
Management attempts to conform to this policy by managing the maturity
distribution of its investment portfolio, emphasizing originations and purchases
of adjustable-interest rate loans, and by managing the product mix and maturity
of its deposit accounts.
 
                                       63
<PAGE>   71
 
     A simple interest rate "gap" analysis by itself may not be an accurate
indicator of how net interest income will be affected by changes in interest
rates. Accordingly, the ALCO Committee also evaluates how the repayment of
particular assets and liabilities is impacted by changes in interest rates.
Income associated with interest-earning assets and costs associated with
interest-bearing liabilities may not be affected uniformly by changes in
interest rates. In addition, the magnitude and duration of changes in interest
rates may have a significant impact on net interest income. For example,
although certain assets and liabilities may have similar maturities or period of
repricing, they may react in different degrees to changes in market interest
rates. Interest rates on certain types of assets and liabilities fluctuate in
advance of changes in general market interest rates, while interest rates on
other types may lag behind changes in general market rates. In addition, certain
assets, such as adjustable-interest rate mortgage loans, have features
(generally referred to as "interest rate caps") which limit changes in interest
rates on a short-term basis and over the life of the asset. In the event of a
change in interest rates, prepayments (on loans and mortgage-backed securities)
and early withdrawal (of deposit accounts) levels also could deviate
significantly from those assumed in calculating the interest rate gap. The
ability of many borrowers to service their debts also may decrease in the event
of an interest rate increase.
 
     Management's strategy is to maintain a relatively balanced interest-rate
risk position to protect its net interest margin from market fluctuations. To
this end, the ALCO Committee reviews, on a quarterly basis, the maturity and
repricing of assets and liabilities.
 
     Management believes that the type and amount of First Commerce's interest
rate sensitive liabilities may reduce the potential impact that a rise in
interest rates might have on First Commerce's net interest income. First
Commerce seeks to maintain a core deposit base by providing quality services to
its customers without significantly increasing its cost of funds or operating
expenses. First Commerce's non-interest bearing demand deposits, NOW accounts,
money market, and savings accounts were 48.19% and 43.69% of total deposits at
December 31, 1996 and 1995, respectively. These accounts bore a weighted average
interest rate of 1.48% and 1.56% during the years ended December 31, 1996 and
1995, respectively. Management anticipates that these accounts will continue to
comprise a significant portion of First Commerce's total deposit base. First
Commerce also maintains a relatively large portfolio of liquid assets in order
to reduce its overall exposure to changes in market interest rates. At December
31, 1996 and December 31, 1995, the Bank's liquidity ratios were 36.01% and
31.35%, respectively. First Commerce also maintains a "floor," or minimum rate,
on certain of its floating or prime based loans. These floors allow First
Commerce to continue to earn a higher rate when the floating rate falls below
the established floor rate.

FINANCIAL CONDITION
 
  Lending Activities
 
     A significant source of First Commerce's income is the interest earned on
its loan portfolio. At December 31, 1996, First Commerce's total assets were
$106.0 million and its loans receivable, net were $66.4 million or 62.65% of
total assets. At December 31, 1995, First Commerce's total assets were $113.1
million and its loans receivable, net were $70.3 million or 62.14% of total
assets. The decrease in total loans receivable

     The increase in loan repayments during 1996 from 1995 was primarily due to
the emphasis placed by the Bank's management during 1996 on managing the
increase in non-performing assets rather than soliciting new loans and getting
non-performing and marginal loans repaid.
 
     The Bank's primary market area consists of Polk County, Florida. This area
is located approximately 25 miles southwest of Walt Disney World and its related
parks and resorts, 45 miles southwest of Orlando, and 55 miles east of Tampa.
The principal economic activities of the area include citrus, services,
miscellaneous manufacturing (including wholesale and retail trade),
distribution, mining, finance, insurance, real estate, utilities, tourism and
trucking. There is no assurance that this area will continue to experience
economic growth. Adverse conditions in any one or more of the industries
operating in such markets or a slow-down in general economic conditions could
have an adverse effect on the Bank.
 
     Lending activities are conducted pursuant to a written policy which has
been adopted by the Bank. Each loan officer has defined lending authority beyond
which loans, depending upon their type and size, must be reviewed and approved
by a loan committee comprised of certain officers and directors of the Bank.
 
     As of December 31, 1996 and 1995, the composition of First Commerce's loan

  Asset Quality
 
     Management seeks to maintain quality assets through sound underwriting and
sound lending practices. The largest category of loans in First Commerce's loan
portfolio are collateralized by commercial real estate mortgages. As of December
31, 1996 and 1995, 44.74%, and 34.36%, respectively, of the total loan portfolio
were collateralized by this type of property. The level of delinquent loans and
other real estate owned also is relevant to the credit quality of a loan
portfolio. As of December 31, 1996, total non-performing assets were $2.8
million or 2.60% of total assets, compared to $2.1 million or 1.86% of total
assets as of December 31, 1995.
 
     The commercial real estate mortgage loans in First Commerce's portfolio
consist of fixed- and adjustable-interest rate loans which were originated at
prevailing market interest rates. The Bank's policy has been to originate
commercial real estate mortgage loans predominantly in its primary market area,
except for those loans purchased from FSB/Osceola. Commercial real estate
mortgage loans are generally made in amounts up to 75% of the appraised value of
the property securing the loan and entail significant additional risks compared
to residential mortgage loans. In making commercial real estate loans, the Bank
primarily considers the net operating income generated by the real estate to
support the debt service, the financial resources and income level and
managerial expertise of the borrower, the marketability of the collateral and
the Bank's lending experience with the borrower.
 
     Unlike residential mortgage loans, which, generally, are made on the basis
of the borrower's ability to make repayment from his employment and other
income, and which are collateralized by real property whose value tends to be
more readily ascertainable, commercial loans typically are underwritten on the
basis of the borrower's ability to make repayment from the cash flow of his
business and, generally, are collateralized by business assets, such as accounts
receivable, equipment and inventory. As a result, the availability of funds for
the repayment of commercial loans may be substantially dependent on the success
of the business itself, which is subject to adverse conditions in the economy.
Commercial loans also entail certain additional risks since they usually involve
large loan balances to single borrowers or a related group of borrowers,
resulting in a more concentrated loan portfolio. Further, the collateral
underlying the loans may depreciate over time, cannot be appraised with as much
precision as residential real estate, and may fluctuate in value based on the
success of the business.
 
     From time to time, the Bank will originate loans on an unsecured basis. As
of December 31, 1996 and 1995, unsecured loans totaled $4.6 million and $5.3
million, respectively.
 
     Loan concentrations are defined as amounts loaned to a number of borrowers
engaged in similar activities which would cause them to be similarly impacted by
economic or other conditions. First Commerce, on a
 
                                       67
<PAGE>   75
 
routine basis, monitors these concentrations in order to consider adjustments in
its lending practices to reflect economic conditions, loan to deposit ratios,
and industry trends. As of December 31, 1996 and 1995, no concentration of loans
within any portfolio category to any group of borrowers engaged in similar
activities or in a similar business exceeded 10% of total loans, except that as
of such dates, loans collateralized with mortgages on real estate represented
68.62% and 60.80%, respectively, of the loan portfolio and were to borrowers in
varying activities and businesses.
 
     The Loan Committee of the Board of Directors of the Bank concentrates its
efforts and resources, and that of its senior management and lending officers,
on loan review and underwriting procedures. Internal controls include ongoing
reviews of loans made to monitor documentation and the existence and valuations
of collateral. In addition, management of the Bank has established a review
process with the objective of identifying, evaluating, and initiating necessary
corrective action for marginal loans. The goal of the loan review process is to
address classified and non-performing loans as early as possible.
 
  Classification of Assets
 
     Generally, interest on loans accrues and is credited to income based upon
the principal balance outstanding. It is management's policy to discontinue the
accrual of interest income and classify a loan on non-accrual status when in the
opinion of management, principal or interest is not likely to be paid in
accordance with the terms of the obligation or when principal or interest is
past due 90 days or more unless, in the determination of management, the
principal and interest on the loan are well collateralized and in the process of
collection. Consumer installment loans are generally charged-off after 90 days
of delinquency unless adequately collateralized and in the process of
collection. Loans are not returned to accrual status until principal and
interest payments are brought current and future payments appear reasonably
certain. Interest accrued and unpaid at the time a loan is placed on non-accrual
status is charged against interest income.
 
     Real estate acquired by First Commerce as a result of foreclosure or by
deed in lieu of foreclosure is classified as other real estate owned ("OREO").
OREO properties are recorded at the lower of cost or fair value less estimated
selling costs, and the estimated loss, if any, is charged to the allowance for
credit losses at the time it is transferred to OREO. Further write-downs in OREO
are recorded at the time management believes additional deterioration in value
has occurred and are charged to non-interest expense.
 
     Interest income that would have been recorded under the original terms of
loans on non-accrual status and interest income actually recognized was $309,000
and $126,000, respectively, for the year ended December 31, 1996, and $144,000
and $28,000, respectively, for the year ended December 31, 1995.
 
     On January 1, 1995, First Commerce adopted Statements of Financial
Accounting Standards No. 114 and 118. These Statements address the accounting by
creditors for impairment of certain loans and generally require First Commerce
to identify loans, for which full repayment of principal and interest will
probably not be received, as impaired loans. The Statements require that
impaired loans be valued at the present value of expected future cash flows,
discounted at the loan's effective interest rate, or at the observable market
price of the loan, or the fair value of the underlying collateral if the loan is
collateral dependent. First Commerce has implemented the Statements by modifying
its quarterly review of the adequacy of the allowance for credit losses to also
identify and value impaired loans in accordance with guidance in the Statements.
As a result of First Commerce's review, impaired loans totaled $1.9 million and
$1.2 million and the allowance for credit losses related to these loans totaled
$548,000 and $156,000 as of December 31, 1996 and 1995, respectively. The
average balance of impaired loans amounted to approximately $1.5 million and
$795,000 during the years ended December 31, 1996 and 1995, respectively. The
adoption of the Statements did not have a material effect on the results of
operations for the year ended December 31, 1995.

     As of December 31, 1996, loans on non-accrual status totaled $2.6 million
and consisted primarily of five customer relationships totaling $2.2 million or
85% of total non-accruing loans.
 
     The first customer relationship consisted of a commercial real estate
mortgage that had a balance of $729,000 as of December 31, 1996. After 1996, the
obligors on this loan agreed to increase the balance of the loan by $159,000 so
that the proceeds could be used to repay First Commerce for a previously
charged-off loan by one of the principals and for attorneys' fees incurred by
First Commerce. The mortgage loan has a balance of $888,000 and is
collateralized with a first mortgage on a 35 acre recreational vehicle park and
fish camp. During 1996, the customer made interest payments which brought the
loan to a current status. During the first quarter of 1997, the customer paid
interest in advance to September 1, 1997. This loan remains on non-accrual
status.
 
     The second customer relationship consisted of three commercial loans
totaling $291,000 at December 31, 1996. During the first quarter of 1997,
management charged off $168,000 of the loans, bringing the outstanding balance
to market value. The credit is collateralized by accounts receivable, high dump
trailers and assignment of leases on high dump trailers. The Bank is receiving
the lease payments pursuant to the assignments of the leases. These loans remain
on a non-accrual status.

     The third relationship consisted of two loans totaling $195,000. The credit
is secured by commercial real estate and a residential property. During the
first quarter of 1997, the customer reaffirmed the debt and it was restructured
under a new repayment schedule. Also during the first quarter of 1997, a
contract for sale of the residential property securing the loan was signed
which, if closed, would result in First Commerce receiving $13,000 to be applied
to the loan balance. These loans remains on a non-accrual status.
 
     The fourth relationship consisted of three loans totaling $232,000 secured
by commercial real estate. Subsequent to December 31, 1996, two of the three
properties were sold paying off two of the three loans. The remaining balance is
$114,000. The remaining loan is being restructured to include additional
collateral consisting of an assignment of a lease agreement with a third party
on the related commercial real estate. This loan remains on a non-accrual
status.
 
     The fifth relationship consisted of four loans of equal size totaling
$771,000 at December 31, 1996. These loans are to four family members and are
secured by stock issued on a closely held family corporation, which has filed
for Chapter 11 reorganization under the Bankruptcy Code. These loans remain on a
non-accrual status.
 
     After December 31, 1996, two additional loans aggregating $508,000 were
placed on non-accrual status. One of these loans is related to the fifth
relationship, and consisted of a funded letter of credit secured by commercial
real estate and an assignment of a life insurance policy having a cash surrender
value of approximately $150,000. The other credit consisted of a $208,000 loan
secured by residential real estate. Payments received on this credit are being
applied to principal only. The loan remains on non-accrual status.
 
     As of December 31, 1996, there were no accruing loans over 90 days
delinquent.
 
     As of December 31, 1996, loans 30 to 89 days delinquent totaled $1,020,000
and consisted primarily of 27 customer relationships totaling $731,000 or 72% of
total loans 30 to 89 days delinquent. The remaining $289,000 of loans 30 to 89
days delinquent consisted of a $181,000 loan secured by residential real estate
and a $108,000 loan secured by commercial real estate.
 
     Following the FSB/CBC Merger, First Commerce experienced a significant
increase in its classified loans. As a result of the increase in First
Commerce's classified loans, management during the fourth quarter of 1995
completed a special review of First Commerce's loan portfolio and instituted a
number of steps intended to improve the identification, evaluation, and
resolution of First Commerce's problem assets. As a result of these actions, the
senior management and loan staff of the Bank meet weekly to review all past due
and non-performing loans and to discuss collection activities. The Board of
Directors of the Bank also reviews problem assets on a monthly basis. In
addition, an independent firm has been retained to conduct periodic loan reviews
and make recommendations for improvement. Management has also instituted steps
to improve underwriting practices. These actions include establishing a bank
credit department separate from the loan origination function, changing loan
origination authorities, hiring a senior vice president in charge of commercial
lending and an assistant vice president in charge of handling nonaccruing loans
and other real estate. Although management believes that the foregoing steps
should contribute to an improvement in First Commerce's asset quality over the
longer term, no estimate can be made at present as to future levels of problem
assets or as to the impact of those assets and related expenses on the financial
condition and results of operations of First Commerce.
 
  Allowance for Credit Losses
 
     In originating loans, First Commerce recognizes that credit losses will be
experienced and that the risk of loss will vary with, among other things, the
type of loan being made, the credit worthiness of the borrower over the term of
the loan and, in the case of a collateralized loan, the quality of the
collateral for the loan, as well as general economic conditions. As a matter of
policy, First Commerce maintains an allowance for credit losses. The amount
provided for credit losses during any period is based on an evaluation by
management of the amount needed to maintain the allowance at a level sufficient
to cover anticipated losses and the inherent risk of losses in the loan
portfolio. In determining the amount of the allowance, management considers the
dollar amount of loans outstanding, its assessment of known or potential problem
loans, current economic conditions,
 
                                       70
<PAGE>   78
 
the risk characteristics of the various classifications of loans, credit record
of its borrowers, the fair market value of underlying collateral and other
factors. Specific allowances are provided for individual loans when ultimate
collection is considered questionable by management after reviewing the current
status of loans which are contractually past due and considering the fair value
of the underlying collateral for each loan. See "-- Results of
Operations -- Provision for Credit Losses."
 
     Management continues to actively monitor First Commerce's asset quality and
to charge-off loans against the allowance for credit losses when appropriate or
to provide specific loss allowances when necessary. Although management believes
that it uses the best information available at the time to make determinations
with respect to allowance for credit losses, subsequent adjustments to the
allowance for credit losses may be necessary if future economic conditions or
other facts differ from the assumptions used in making the initial
determinations or if regulatory policies change.
 
     As of December 31, 1996 and 1995, the allocation of the allowance for
credit losses was as follows:

     During the year ended December 31, 1996, the provision for credit losses
was $974,000, compared to $1.2 million during the year ended December 31, 1995,
or a decrease of $217,000.
 
     The Bank continued to provide for loan losses throughout 1996, especially
in the fourth quarter. During the fourth quarter, $406,000 was added to the
allowance for credit losses, which was in recognition of an increase in charged
off loans in the month of December 1996 of $595,000. Total charged off loans,
net of recoveries, were $741,000 for 1996 and $742,000 for 1995.
 
     During 1996, $923,000 of loans were charged off, of which $306,000
consisted of unsecured loans. The three largest charged off loans totaled
$617,000, representing 67% of the total loans charged off. The first charged off
loan was a $121,000 commercial real estate loan. The second charged off loan was
the aggregate balance of three separate commercial real estate loans of $121,000
to one borrower. The third charged off loan was a $375,000 commercial loan,
secured by an assignment of proceeds of fruit sales. The Bank was unsuccessful
in its efforts or decided it was too costly to protect or seize the related
collateral on these three loans.

     First Commerce has adopted Statement of Financial Accounting Standards No.
115 ("FAS 115"), which requires companies to classify investments securities,
including mortgage-backed securities as either held-to-maturity,
available-for-sale, or trading securities. Securities classified as
held-to-maturity are carried at amortized cost. Securities classified as
available-for-sale are reported at fair value, with unrealized gains and losses,
net of tax effect, reported as a separate component of stockholders' equity.
Securities classified as trading securities are recorded at fair value, with
unrealized gains and losses included in earnings. At December 31, 1996, all
mortgage-backed securities were classified as available-for-sale. As a result of
the adoption of FAS 115, under which First Commerce expects to continue to
classify certain of its mortgage-backed securities as available-for-sale,
changes in the underlying market values of such securities could have a material
adverse effect on First Commerce's capital position. Typically, an increase in
interest rates results in a decrease in underlying market value and an increase
in the level of principal repayments on mortgage-backed securities. As a result
of a general decrease in interest rates during the past year, decreases in the
market value of available-for-sale mortgage-backed securities resulted in a
decrease in stockholders' equity of $33,000 at December 31, 1996. Such decrease
represents the impact of changes in interest rates on the value and maturity of
these investments.
 
     As allowed by "A Guide to Implementation of Statement 115 on Accounting for
Certain Investments in Debt and Equity Securities" issued by the Financial
Accounting Standards Board, First Commerce reevaluated the classification of its
investment securities and on December 12, 1995, reclassified securities with an
amortized cost of $2.1 million and a fair value of $2.1 million from securities
held-to-maturity to securities available-for-sale.

     First Commerce invests in mortgage-backed securities that are guaranteed as
to principal and interest by the Government National Mortgage Association
("GNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC"), or the Federal
National Mortgage Association ("FNMA"). Although mortgage-backed securities
generally have a lower yield than loans, mortgage-backed securities increase the
quality of First Commerce's assets by virtue of the guarantees that back them,
are more liquid than individual mortgage loans and may be used to collateralize
borrowings or other obligations of First Commerce. Due to repayment and
prepayments of the underlying loans, the actual maturities of mortgage-backed
securities are substantially less than the scheduled maturities. First
Commerce's portfolio of mortgage-backed securities was purchased with an
anticipated average life of approximately three years. Changes in interest and
prepayment rates may also affect the average life, yield to maturity, and
related market value of First Commerce's mortgage-backed securities. Changes in
the market values of First Commerce's mortgage-backed securities may result in

  Deposit Activities
 
     Deposits are the major source of First Commerce's funds for lending and
other investment purposes. Deposits are attracted principally from within First
Commerce's primary market area through the offering of a broad variety of
deposit instruments including checking accounts, money market accounts, regular
savings accounts, term certificate accounts (including "jumbo" certificates in
denominations of $100,000 or more) and retirement savings plans. As of December
31, 1996 and 1995, the distribution by type of First Commerce's deposit accounts
was as follows:

     Time deposits included individual retirement accounts ("IRAs") totalling
$6.0 million at December 31, 1996 and 1995, all of which are in the form of
certificates of deposit.
 
     First Commerce's deposits decreased to $94.7 million as of December 31,
1996, from 101.9 million as of December 31, 1995, or a decrease of $7.2 million
or 7.06%. This decrease was primarily attributable to the $7.8 million, or
13.6%, decrease in deposits of the Bank. During 1996, the Bank repriced deposits
at a lower rate resulting in a decrease in deposits.
 
     Maturity terms, service fees and withdrawal penalties are established by
the Bank on a periodic basis. The determination of rates and terms is predicated
on funds acquisition and liquidity requirements, rates paid by competitors,
growth goals and federal regulations.
 
     FDIC regulations limit the ability of certain insured depository
institutions to accept, renew, or rollover deposits by offering rates of
interest which are significantly higher than the prevailing rates of interest on
deposits offered by other insured depository institutions having the same type
of charter in such depository institutions' normal market area. Under these
regulations, "well capitalized" depository institutions may accept, renew, or
roll over deposits at such rates without restriction, "adequately capitalized"
depository institutions may accept, renew or roll over deposits at such rates
with a waiver from the FDIC (subject to certain restrictions on payments of
rates), and "undercapitalized" depository institutions may not accept, renew or
roll over deposits at such rates. As of December 31, 1996, the Bank met the
definition of a "well capitalized" depository institution.
 
     First Commerce does not have a concentration of deposits from any one
source, the loss of which would have a material adverse effect on First
Commerce. Management believes that substantially all of First Commerce's
depositors are residents in its primary market area. First Commerce currently
does not accept brokered deposits.
 
     Time deposits of $100,000 and over, public fund deposits and other large
deposit accounts tend to be short-term in nature and more sensitive to changes
in interest rates than other types of deposits and, therefore, may be a less
stable source of funds. In the event that existing short-term deposits are not
renewed, the resulting loss of the deposited funds could adversely affect First
Commerce's liquidity. In a rising interest rate market, such short-term deposits
may prove to be a costly source of funds because their short-term nature
 
                                       75
<PAGE>   83
 
facilitates renewal at increasingly higher interest rates, which may adversely
affect First Commerce's earnings. However, the converse is true in a falling
interest-rate market where such short-term deposits are more favorable to First
Commerce.

IMPACT OF INFLATION AND CHANGING PRICES
 
     The financial statements and related data concerning First Commerce have
been prepared in accordance with generally accepted accounting principles which
require 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 principal element of First Commerce's
earnings is interest income which may be significantly affected by the level of
inflation and by government monetary and fiscal policies adopted in response to
inflationary or deflationary pressures.
 
     Inflation affects the reported financial condition and results of
operations of all companies. However, the majority of assets and liabilities of
financial institutions are monetary in nature and therefore differ greatly from
most commercial and industrial companies that have significant investments in
fixed assets or inventories. Inflation does have an important impact on the
growth of total assets and the resulting need to increase equity capital at
higher than normal rates in order to maintain an appropriate equity to assets
ratio Inflation also is a factor which may influence interest rates, yet the
frequency and magnitude of interest rate fluctuations do not necessarily
coincide with changes in the general inflation rate. In an effort to cope with
the effects of inflation, First Commerce attempts to monitor its interest-rate
sensitivity gap position, as discussed above. In addition, a periodic review of
banking services and products is conducted to adjust pricing in view of current
costs.
 
FUTURE ACCOUNTING REQUIREMENTS
 
     Statement of Financial Accounting Standards No. 125 ("FAS 125"),
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities" provides accounting and reporting standards for transfers and
servicing of financial assets and extinguishments of liabilities based on
consistent application of a financial components approach that focuses on
control. FAS 125 provides standards for distinguishing transfers of financial
assets from transfers that are secured borrowings. The accounting and disclosure
requirements of FAS 125 will become effective for First Commerce beginning
January 1, 1997. Management is in the process of evaluating FAS 125, but does
not anticipate that FAS 125 will have a material impact on First Commerce's
financial statements.

                             BUSINESS OF BANCGROUP
 
GENERAL
 
     BancGroup is a bank holding company registered under the BHCA. It was
organized in 1974 under the laws of Delaware and has operated under its current
name and management since 1981. BancGroup operates wholly owned commercial
banking subsidiaries in the states of Alabama, Florida, Georgia and Tennessee,
each under the name "Colonial Bank." Colonial Bank conducts a full service
commercial banking business in the state of Alabama through 110 branches. In
Tennessee, Colonial Bank conducts a general commercial banking business through
three branches. In Georgia, Colonial Bank operates eleven branches in the
Atlanta area and three branches in the Dalton area. In Florida, Colonial Bank
operates eleven branches in the Orlando and Ormond Beach areas, nine branches in
Dade, Broward and Palm Beach counties, and six branches in Eustis and Lake
County. Colonial Mortgage Company, a subsidiary of Colonial Bank in Alabama, is
a mortgage banking company which services approximately $10.6 billion in
residential loans and which originates mortgages in 37 states through 6 regional
offices. BancGroup's commercial banking loan portfolio is comprised primarily of
commercial real estate loans (24%) and residential real estate loans (43%), a
significant portion of which is located within the State of Alabama. BancGroup's
growth in loans over the past several years has been concentrated in commercial
and residential real estate loans.
 
     BancGroup plans to merge all of its existing subsidiary banks in Florida,
Georgia and Tennessee into its Alabama bank subsidiary, Colonial Bank, no later
than July 1, 1997. Thereafter, Colonial Bank will conduct business as a single
bank subsidiary of BancGroup in the states of Alabama, Florida, Georgia and
Tennessee.
 
PROPOSED AFFILIATE BANKS
 
     Since December 31, 1996, BancGroup has acquired five banking institutions,
First Family, Tomoka, and Jefferson, located in Florida, Bankshares, located in
Georgia, and Shamrock, located in Alabama, with aggregate assets and
stockholders' equity acquired of $896.9 and $66.6 million, respectively. These
acquisitions are included in the pro forma statements contained herein.
 
     See "THE COLONIAL BANCGROUP, INC. AND SUBSIDIARIES -- Condensed Pro Forma
Statements of Condition (Unaudited)."
 
     BancGroup has entered into a definitive agreement dated as of March 6,
1997, to acquire Great Southern Bancorp ("Great Southern"). Great Southern is a
Florida corporation and is a holding company for Great Southern Bank located in
West Palm Beach, Florida. Great Southern will merge with BancGroup and following
such merger Great Southern Bank will merge with BancGroup's existing Alabama
bank subsidiary, Colonial Bank. Based on the market price of BancGroup Common
Stock as of March 24, 1997, a total of 899,698 shares of BancGroup Common Stock
would be issued to the stockholders of Great Southern. The actual number of
shares of BancGroup Common Stock to be issued in this transaction will depend
upon the market value of such Common Stock at the time of the merger, subject to
maximum and minimum amounts to be issued. This transaction is subject to, among
other things, approval by the stockholders of Great Southern and approval by
appropriate regulatory authorities. At December 31, 1996, Great Southern has
assets of $119.2 million, deposits of $107.8 million and stockholders' equity of
$10.1 million.

                           BUSINESS OF FIRST COMMERCE
 
GENERAL
 
     First Commerce was incorporated under the laws of the State of Florida on
March 28, 1984 under the name First Sterling Bancshares, Inc. ("FSB"). On August
31, 1995, FSB closed the merger of Commerce Bank Corporation ("CBC") with and
into FSB (the "FSB/CBC Merger"). Upon effectiveness of the FSB/CBC Merger, the
corporate name of FSB was changed to First Commerce Banks of Florida, Inc. First
Commerce is a registered bank holding company under the Bank Holding Company Act
of 1956, as amended (the "BHC Act"), and owns 99.7% of the voting shares of
First Commerce Bank of Polk County (the "Bank").
 
     The Bank commenced operations in 1982 under the name First Sterling Bank.
Upon the effectiveness of the FSB/CBC Merger, Commerce Bank of Central Florida
(a subsidiary of CBC) was merged with and into First Sterling Bank and the name
of First Sterling Bank was changed to First Commerce Bank of Polk County. The
Bank is a state banking corporation subject to regulation by the Federal Deposit
Insurance Corporation ("FDIC") and the Florida Department of Banking and Finance
(the "Florida Department"). The Bank's operations are conducted from its main
office located in Winter Haven, Florida, a branch office located in Auburndale,
Florida, two branch offices located in Lakeland, Florida, and a branch office
located in Polk City, Florida.
 
     The Bank provides a range of consumer and commercial banking services to
individuals, businesses and industries. The basic services offered by the Bank
include: demand interest bearing and noninterest bearing accounts, money market
deposit accounts, NOW accounts, time deposits, safe deposit services, credit
cards, cash management, direct deposits, notary services, money orders, night
depository, travelers' checks, cashier's checks, domestic collections, savings
bonds, bank drafts, drive-in tellers, and banking by mail. In addition, the Bank
makes secured and unsecured commercial and real estate loans and issues stand-by
letters of credit. The Bank provides automated teller machine ("ATM") cards, as
a part of the HONOR ATM network, thereby permitting customers to utilize the
convenience of larger ATM networks. The Bank does not have trust powers and,
accordingly, no trust services are provided.
 
     The revenues of the Bank are primarily derived from interest on, and fees
received in connection with, real estate and other loans, and from interest and
dividends from investment and mortgage-backed securities, and short-term
investments. The principal sources of funds for the Bank's lending activities
are its deposits, repayment of loans, and the sale and maturity of investment
securities. The principal expenses of the Bank are the interest paid on
deposits, and operating and general administrative expenses.
 
     As is the case with banking institutions generally, the Bank's operations
are materially and significantly influenced by general economic conditions and
by related monetary and fiscal policies of financial institution regulatory
agencies, including the Federal Reserve, the FDIC, and the Florida Department.
Deposit flows and costs of funds are influenced by interest rates on competing
investments and general market rates of interest. Lending activities are
affected by the demand for financing of real estate and other types of loans,
which in turn is affected by the interest rates at which such financing may be
offered and other factors affecting local demand and availability of funds. The
Bank faces strong competition in the attraction of deposits (its primary source
of lendable funds) and in the origination of loans.
 
DEPOSIT ACTIVITIES
 
     Deposits are the major source of the Bank's funds for lending and other
investment activities. The Bank considers the majority of its regular savings,
demand, NOW and money market deposit accounts to be core deposits. These
accounts comprised 48.6% of the Bank's total deposits at December 31, 1996. At
December 31, 1996, 51.4% of the Bank's deposits were certificates of deposit.
Generally, the Bank attempts to maintain the rates paid on its deposits at a
competitive level. Time deposits of $100,000 and over made up 6.3% of the Bank's
total deposits at December 31, 1996. The majority of the deposits of the Bank
are generated from Polk County. The Bank does not accept brokered deposits. For

Bank's deposit activities, see "First Commerce Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Financial
Condition -- Deposit Activities".
 
LENDING ACTIVITIES
 
     The Bank offers a range of lending services, including real estate,
consumer and commercial loans, to individuals and small businesses and other
organizations that are located in or conduct a substantial portion of their
business in the Bank's market area. The Bank's loans receivable, net at December
31, 1996 were $66.4 million, or 62.6% of total assets. The interest rates
charged on loans vary with the degree of risk, maturity, and amount of the loan,
and are further subject to competitive pressures, money market rates,
availability of funds, and government regulations. The Bank has no foreign loans
or loans for highly leveraged transactions.
 
     The Bank's loans are concentrated in three major areas: real estate loans,
commercial loans, and consumer loans. As of December 31, 1996, 69.6% of the
Bank's loan portfolio consisted of loans secured by mortgages on real estate and
20.1% of the loan portfolio consisted of commercial loans. At the same date,
6.8% of the Bank's loan portfolio consisted of unsecured loans.
 
     The Bank's real estate loans are secured by mortgages and consist primarily
of loans to individuals and businesses for the purchase, improvement of or
investment in real estate and for the construction of single-family residential
units or the development of single-family residential building lots. These real
estate loans may be made at fixed- or variable-interest rates. The Bank
generally does not make fixed-interest rate commercial real estate loans for
terms exceeding five years. Loans in excess of three years generally have
adjustable-interest rates. The Bank's residential real estate loans generally
are repayable in monthly installments based on up to a 30-year amortization
schedule with variable-interest rates.
 
     The Bank's commercial loans include loans to individuals and
small-to-medium sized businesses located primarily in Polk County for working
capital, equipment purchases, and various other business purposes. A majority of
the Bank's commercial loans are secured by equipment or similar assets, but
these loans may also be made on an unsecured basis. Commercial loans may be made
at variable- or fixed-interest rates. Commercial lines of credit are typically
granted on a one-year basis, with loan covenants and monetary thresholds. Other
commercial loans with terms or amortization schedules of longer than one year
will normally carry interest rates which vary with the prime lending rate and
will become payable in full and are generally refinanced in three to five years.
 
     The Bank's consumer 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. The majority of these loans are
for terms of less than five years and are secured by liens on various personal
assets of the borrowers, but consumer loans may also be made on an unsecured
basis. Consumer loans are made at fixed-and variable-interest rates, and are
often based on up to a five-year amortization schedule.
 
     Loan originations are derived from a number of sources, including direct
solicitation by the Bank's loan officers, existing customers and borrowers,
advertising, walk-in customers and, in some instances, referrals from brokers.
 
     For additional information on the Bank's lending activities, see "First
Commerce Management's Discussion and Analysis of Financial Condition and Results
of Operations -- Financial Condition -- Lending Activities," and "-- Asset
Quality."
 
INVESTMENTS
 
     The Bank invests a portion of its assets in U.S. Treasury and U.S.
Government agency obligations, FHLMC and FNMA mortgage-backed securities, state,
county and municipal obligations, certificates of deposit, collateralized
mortgage obligations ("CMO's"), and federal funds sold. The Bank's investments
are managed in relation to loan demand and deposit growth, and are generally
used to provide for the investment of excess funds at reduced yields and risks
relative to yields and risks of the loan portfolio, while providing liquidity to
fund increases in loan demand or to offset fluctuations in deposits. For
additional information relating to First Commerce's investments, see "First
Commerce Management's Discussion and Analysis of

Consolidated Financial Statements.
 
FSB/OSCEOLA SALE
 
     On May 1, 1995, First Commerce sold all of the 240,000 shares of common
stock of First Sterling Bank of Osceola County ("FSB/Osceola") (which
constituted 80% of the outstanding shares of FSB/Osceola stock) owned by First
Commerce to certain unaffiliated individuals. The purchasers of FSB/Osceola paid
First Commerce a cash purchase price of $1.8 million, or $7.69 per share, which
was approximately equal to 1.45 times the adjusted shareholders' equity per
share of FSB/Osceola. The terms of the transaction were the result of
arms-length negotiations between First Commerce and the purchasers. The purchase
price allowed First Commerce to achieve a profit on the sale, due to the premium
over the book value being paid by the purchasers. At the closing of the sale,
FSB/Osceola also issued to First Commerce warrants to purchase 24,000 shares of
FSB/Osceola common stock exercisable over a five-year period at an exercise
price of $5.30 per share. No value for the warrants issued by FSB/Osceola to
First Commerce is carried on First Commerce's balance sheet.
 
     The terms of the agreement for the sale by First Commerce of the
FSB/Osceola shares to the purchasers provided that First Commerce would
repurchase FSB/Osceola's other real estate owned and classified loans (which the
purchasers did not want FSB/Osceola to retain as a result of the sale) and that
the Bank would purchase substantially all of the FSB/Osceola loans in several
installments over a one-year period. During 1995, $4.6 million of FSB/Osceola
loans were purchased ($4.4 million by the Bank and $269,000 by First Commerce),
and during 1996, $1.9 million of FSB/Osceola loans were purchased ($1.4 million
by the Bank and $450,000 by First Commerce). See "First Commerce Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Sale
of FSB/Osceola."
 
EMPLOYEES
 
     As of December 31, 1996, First Commerce employed 61 full-time employees and
one part-time employee. The employees are not represented by a collective
bargaining unit. First Commerce and the Bank consider relations with employees
to be good.
 
PROPERTIES
 
     The main office of First Commerce and the Bank is located at 141 Central
Avenue East, Winter Haven, Florida 33880, in a four story building of
approximately 28,065 square feet, approximately 17,372 of which is used by the
Bank and leased by the Bank from TBG Properties, Inc., a corporation in which
eight of the Bank directors (two of whom also serve as First Commerce directors)
are shareholders. The lease agreement, with renewal options, expires in 2004.
Under the lease agreement, the Bank has the option to purchase the building
during the term of the lease for a purchase price equal to the fair market value
as determined by a mutually agreed upon M.A.I. appraiser and, if the parties
cannot mutually agree upon an appraiser, then by two M.A.I. appraisers (one
selected by TBG Properties, Inc. and one selected by the Bank, with one-half of
the costs of the appraisals to be paid by the Bank). The purchase price will
equal the average of the two appraisals if they do not vary by more than 10%
and, if they do, the two appraisers will select a third M.A.I. appraiser, and
the purchase price will equal the average of the three appraisals. Either party
has the right not to proceed with the purchase and sale if it so notifies the
other within 10 days after the amount of the purchase price has been determined
pursuant to the appraisal process.
 
     The Bank also has branch offices located at 3660 Havendale Boulevard,
Auburndale, Florida 33823, in a two-story building of approximately 7,500 square
feet which is owned by the Bank; at 2215 South Combee Road, Lakeland, Florida
33801 in a one story building of approximately 2,500 square feet which is owned
by the Bank; at 3900 South Florida Avenue, Lakeland, Florida 33813 in a one
story building of approximately 1,100 square feet which is leased by the Bank
(under a month to month lease); and at 212 North Commonwealth Avenue, Polk City,
Florida 33868 in a one story building of approximately 1,300 square feet which
is owned by the Bank.

LEGAL PROCEEDINGS
 
     First Commerce and the Bank are periodically parties to or otherwise
involved in legal proceedings arising in the normal course of business, such as
claims to enforce liens, claims involving the making and servicing of real
property loans, and other issues incident to their respective businesses.
Management does not believe that there is any pending or threatened proceeding
against First Commerce or the Bank which, if determined adversely, would have a
material adverse effect on First Commerce's consolidated financial position.

                         ADJOURNMENT OF SPECIAL MEETING
 
     Approval of the Agreement by First Commerce's shareholders requires the
affirmative vote of at least a majority of the total votes eligible to be cast
at the Special Meeting. In the event there are an insufficient number of shares
of First Commerce Common Stock present in person or by proxy at the Special
Meeting to approve the Agreement, First Commerce's Board of Directors intends to
adjourn the Special Meeting to a later date provided a majority of the shares
present and voting on the motion have voted in favor of such adjournment. The
place and date to which the Special Meeting would be adjourned would be
announced at the Special Meeting. Proxies voted against the Agreement and
abstentions will not be voted to adjourn the Special Meeting. Abstentions and
broker non-votes will not be voted on this matter but will not count as "no
votes." If it is necessary to adjourn the Special Meeting and the adjournment is
for a period of not more than 30 days from the original date of the Special
Meeting, no notice of the time and place of the adjourned meeting need be given
the shareholders, other than an announcement made at the Special Meeting.
 
     The effect of any such adjournment would be to permit First Commerce to
solicit additional proxies for approval of the Agreement. While such an
adjournment would not invalidate any proxies previously filed as long as the
record date for the adjourned meeting remained the same, including proxies filed
by shareholders voting against the Agreement, an adjournment would afford First
Commerce the opportunity to solicit additional proxies in favor of the
Agreement.
 
                                 OTHER MATTERS
 
     The Board of Directors of First Commerce is not aware of any business to
come before the Special Meeting other than those matters described above in this
Prospectus. If, however, any other matters not now known should properly come
before the Special Meeting, the proxy holders named in the accompanying proxy
will vote such proxy on such matters as determined by a majority of the Board of
Directors of First Commerce.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
First Commerce Banks of Florida, Inc.
 
     We have audited the accompanying consolidated statements of condition of
First Commerce Banks of Florida, Inc. and subsidiary as of December 31, 1996 and
1995, and the related consolidated statements of income, stockholders' equity,
and cash flows for the years then ended. These consolidated financial statements
are the responsibility of the Holding Company's management. Our responsibility
is to express an opinion on these consolidated 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated 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, based on our audits, the consolidated financial statements
referred to above present fairly, in all material respects, the financial
position of First Commerce Banks of Florida, Inc. and subsidiary as of December
31, 1996 and 1995, and the results of their operations and their cash flows for
the years then ended in conformity with generally accepted accounting
principles.

              FIRST COMMERCE BANKS OF FLORIDA, INC. AND SUBSIDIARY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Business Activities.  First Commerce Banks of Florida, Inc. (Holding
Company) is a bank holding company for its majority owned subsidiary, First
Commerce Bank of Polk County (Bank). The Bank provides financial services to
individuals and corporate customers.
 
     Consolidation.  The consolidated financial statements include the accounts
of the Holding Company and its majority owned subsidiary, Bank. The operations
of First Sterling Bank of Osceola County (FSBO) are included in the consolidated
financial statements for the period prior to May 1, 1995. The minority interest
represents a .30 percent ownership interest in the common stock of the Bank held
by third parties. All material intercompany accounts and transactions are
eliminated.
 
     Cash and Cash Equivalents.  For purposes of the statements of cash flows,
the Holding Company defines cash and cash equivalents as cash and due from
banks, which includes currency on hand, demand deposits with other financial
institutions and federal funds sold.
 
     Use of Estimates.  The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for credit losses. While management
uses available information to recognize losses on loans, future additions to the
allowances may be necessary based on changes in local economic conditions. In
addition, regulatory agencies, as an integral part of their examination process,
periodically review the Bank's allowances for credit losses. Such agencies may
require the Bank to recognize changes to the allowances based on their judgments
about information available to them at the time of their examination. Because of
these factors, it is possible that the allowances for credit losses and
foreclosed real estate may materially change in the future.
 
     Investment Securities.  The Bank follows Statement of Financial Accounting
Standards No. 115 which requires investment securities that the Bank has the
positive intent and ability to hold to maturity to be classified as held to
maturity securities and reported at amortized cost. Investment securities that
are held principally to sell in the near term are classified as trading
securities and reported at fair value, with unrealized gains and losses included
in income. Investment securities not classified as either held to maturity
securities or trading securities are classified as available for sale securities
and reported at fair value, with unrealized gains and losses excluded from
earnings and reported in a separate component of stockholders' equity.
 
     Gains and losses on the sale of investment securities are computed on the
basis of specific identification.
 
     Loans Receivable and Allowance for Credit Losses.  Loans are stated at the
amount of unpaid principal, less an allowance for credit losses and net of
deferred loan fees and unearned discounts. Interest on loans is recognized over
the term of the loan and is calculated using the simple interest method on
principal amounts outstanding. Unearned discounts on installment loans are
recognized as income over the terms of the loans using the interest method. Loan
origination and commitment fees and certain direct origination costs are
deferred and amortized as a yield adjustment over the lives of the related loans
using a method that approximates the interest method.
 
     The allowance for credit losses is established through a provision for
credit losses charged to expense. The allowance is an amount which management
believes may become uncollectible based on an evaluation of the loans in the
portfolio and prior loss experience. This evaluation of the potential loss in
the loan portfolio includes a review of all loans for which full collection may
not be reasonably assured and considers the estimated value of the underlying
collateral, loan portfolio composition, historical experience, general

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
economic conditions and other appropriate matters. Loans are charged against the
allowance for credit losses when management believes that collection of the
principal is unlikely.
 
     Loan Impairment and Losses.  On January 1, 1995, the Holding Company and
Bank adopted Statements of Financial Accounting Standards No. 114 and 118. These
Statements address the accounting by creditors for impairment of certain loans.
The Statements generally require the Holding Company and Bank to identify loans,
for which the Holding Company and Bank probably will not receive full repayment
of principal and interest, as impaired loans. The Statements require that
impaired loans be valued at the present value of expected future cash flows,
discounted at the loan's effective interest rate, or at the observable market
price of the loan, or the fair value of the underlying collateral if the loan is
collateral dependent. The Holding Company and Bank have implemented the
Statements by modifying their quarterly review of the adequacy of the allowance
for credit losses to also identify and value impaired loans in accordance with
guidance in the Statements. As a result of the Holding Company and Banks'
review, impaired loans totaled $1,911,000 and $1,182,000 and the allowance for
credit losses related to these loans totaled $548,000 and $156,000 as of
December 31, 1996 and 1995, respectively. The average balance of impaired loans
amounted to approximately $1,547,000 during 1996 and $794,000 during 1995. Cash
receipts recorded as interest income on impaired loans was $51,000 in 1996.
There were no cash receipts on impaired loans in 1995. The adoption of the
Statements did not have a material effect on the results of operations for the
year ended December 31, 1995.
 
     Impairments in accordance with the Statement are recognized by establishing
an allowance for credit losses and a corresponding charge to expenses.
Subsequent changes in impairment are recognized in the same manner in the period
of change.
 
     The Holding Company and Banks' policy is to discontinue accruing interest
on a loan after it has become 90 days delinquent as to payment of principal or
interest unless, in the determination of management, the loan is well secured
and in process of collection. If the ultimate collectibility of principal,
either in whole or in part, is in doubt, any payment received on a loan for
which the accrual of interest has been discontinued is applied to reduce
principal to the extent necessary to eliminate such doubt. If the ultimate
collectibility of principal is not in doubt, interest is credited to income in
the period of recovery. Nonaccrual loans are considered impaired loans, except
for those nonaccrual loans the Holding Company and Bank have sufficient
collateral to collect all principal and interest as specified in the original
loan agreement.
 
     Other Real Estate Owned.  Other real estate acquired in settlement of loans
is carried at the lower of the fair value of the property less the estimated
costs to sell or the Bank's basis in the loan. At the date of acquisition,
losses are charged to the allowance for credit losses. Costs incurred to bring
the property up to the condition for which it is intended are capitalized up to
the property's fair value, while holding costs, legal fees and other direct
costs are expensed. Real property, held by the Bank and not used for banking
purposes, is recorded with other real estate at cost.
 
     Property, Equipment and Depreciation.  Property and equipment are stated at
cost, less accumulated depreciation. Depreciation is computed using the
straight-line method over the estimated useful lives of the assets.
 
     Net Income per Share of Common Stock.  Net income per share of the Holding
Company's common stock is computed by dividing net income for the year by the
weighted average number of shares of common stock outstanding, including common
stock equivalents using the treasury stock method. Warrants and stock options
issued to officers and directors are common stock equivalents. Fully-diluted and
primary earnings per

     Stock Option and Warrant Plans.  Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation", encourages the
Holding Company and Bank to account for employee stock option plans entered into
after December 15, 1995 under a fair value based method of accounting, which
requires compensation costs to be measured at the grant date of options and
recorded over the grantee's service period. Also, the standard provides for
these plans to be accounted for under an intrinsic value method, which
compensation costs are the excess, if any, of the quoted market price of stock
at grant date or other measurement date over the amount the employee must pay to
acquire the stock. The standard also requires the Holding Company and Bank to
disclose the difference in compensation costs between the two methods if the
intrinsic value method is used. The Holding Company and Bank have accounted for
previous plans under the intrinsic value method and will continue to do so on
future plans; however, no new plans were entered into in 1996. There were no
options granted in 1996 and options granted in 1995 approximated fair value;
therefore, there were no significant differences in compensation costs between
the two methods to disclose.
 
     Taxes on Income.  Accounting policies with respect to taxes on income are
described in Note 11.
 
(2) BUSINESS COMBINATIONS
 
     On August 31, 1995, First Sterling Bancshares, Inc. (FSB) merged (the
Merger) with Commerce Bank Corporation (Commerce). In the Merger, all the
outstanding shares of Commerce were exchanged for 746,704 shares of FSB common
stock and $1,000 of cash in lieu of fractional shares. In addition, the name of
FSB was changed to First Commerce Banks of Florida, Inc. At the same time, their
subsidiaries, First Sterling Bank and Commerce Bank of Central Florida, merged
together to become First Commerce Bank of Polk County.

     The Merger with Commerce has been accounted for as a pooling of interests
and all amounts prior to the Merger have been restated to include the results of
operations, financial position and cash flows of FSB and Commerce. Interest and
other income and net earnings for the individual entities during the periods

(3) SALE OF SUBSIDIARY
 
     On May 1, 1995, the Holding Company sold its stock in FSBO to an
unaffiliated third party for approximately $1,845,000. The agreement provided
that the Holding Company purchase any other real estate owned at book value from
FSBO at the date of the sale and the Bank purchase the existing loan portfolio
(including any allowance for credit losses) from FSBO over the one-year period
following the sale at book value. At December 31, 1996, the Bank has no
remaining commitment to purchase loans from FSBO.
 
(4) CASH AND DUE FROM BANKS
 
     The Bank is required to maintain certain average reserve balances pursuant
to regulations of the Federal Reserve Board. These balances must be maintained
in the form of vault cash or non-interest-bearing deposits at a Federal Reserve
Bank. The Bank exceeded this requirement, which was $678,000 and $552,000, at
December 31, 1996 and 1995, respectively.
 
     The Holding Company's cash and due from banks includes $4,699,000 and
$3,696,000 maintained at other banks as of December 31, 1996 and 1995,
respectively. Funds at each bank are federally insured up to $100,000. The
balance of cash not remaining at other banks consists of cash on hand and on
deposit with the Federal Reserve.

     Subsequent to the sale of FSBO by the Holding Company in 1995, the Bank
purchased $4,520,000 and $1,383,000 in loans from FSBO in 1995 and 1996,
respectively. The loans were purchased for the unpaid principal balance reduced
by the related allowance for credit losses and discounts attributed to these
loans, which were transferred to the Bank. Additionally, the Holding Company
purchased $189,000 and $493,000 in loans from FSBO in 1995 and 1996,
respectively. Due to regulatory rules, the Bank could not acquire any nonaccrual
loans so the Holding Company purchased them.

(10) PROFIT SHARING PLAN
 
     Prior to the FSB/Commerce Merger, FSB and Commerce maintained separate
employee benefit plans. Under the 401(k) component of the FSB plan, participants
were able to contribute up to 15 percent, but not less than 1 percent, of their
annual compensation. FSB was required to match the participant's contribution up
to the lower of 50% of the participant's contributions or 6% of participant's
compensation. Commerce had a noncontributory profit sharing plan which covered
all eligible employees. Employer contributions to the Commerce plan were
voluntary and at the discretion of the Board of Directors. The Holding Company
merged the Commerce Plan into the FSB Plan of Florida, Inc., Employee 401(k)
Plan and Trust. Employer contributions under all plans charged to operations
were $30,394 in 1996 and $39,685 in 1995.

(14) COMMITMENTS AND CONTINGENCIES
 
     The Bank leases premises in Winter Haven, Florida from an entity controlled
by certain directors of the Holding Company under a noncancelable lease that
expires December 1999. The agreement contains an option renewal for one
additional five-year period. The agreement requires monthly rental payments as
well as a pro-rata share of the maintenance, property taxes, and insurance on
the premises. The following is a schedule by years of future minimum rental
payments required by the lease:

</TABLE>
 
     The lease agreement contains a purchase option for the Bank to purchase the
premises. The purchase price for the premises will be the fair value on the date
of the exercise of the option as determined by an MAI appraisal.
 
     Rental expense under all operating leases charged to operations was
$259,000 and $230,000 for the years ending December 31, 1996 and 1995,
respectively.
 
     The consolidated financial statements do not reflect various commitments
and contingent liabilities which arise in the normal course of business and
which involve elements of credit risk, interest rate risk and liquidity risk.
These commitments and contingent liabilities are commitments to extend credit
and standby letters of credit and total $10,365,000 at December 31, 1996.
 
     Commitments to extend credit and standby letters of credit include exposure
to some credit loss in the event of nonperformance by the customer. The Bank's
credit policies and procedures for credit commitments and financial guarantees
are the same as those for extension of credit that are recognized on the
consolidated statements of condition. Because these instruments have fixed
maturity dates, and because many of them expire without being drawn upon, they
do not generally present any significant liquidity risk to the Bank. The Bank
has not been required to perform on any financial guarantees during the past two
years and did not incur any losses on its commitments in either 1996 or 1995.
 
     The Bank is party to litigation and claims arising in the normal course of
business. Management, after consultation with legal counsel, believes that the
liabilities, if any, arising from such litigation and claims will not be
material to the Holding Company's financial position.
 
     The Bank has salary continuation agreements with two officers which provide
for payments to the officers or their beneficiaries of $27,900 and $97,600
annually for fifteen years. The Bank is accruing the estimated amount of future
payments to be made under these agreements over the period of the officers'
active employment. The payments begin at the earlier of an officer's retirement
or death.
 
     The Bank has entered into an agreement dated September 1, 1996 with a
former officer. The agreement provides for the Bank to pay the former officer
$108,000, at his discretion, in either a lump sum on September 1, 1997 or in
seven equal annual installments. As of December 31, 1996, the Bank has accrued
an amount equal to the future payments.
 
     The Bank has entered into an employment agreement with an officer which
expires August 1997. The agreement provides for annual salaries, benefits and
covenants not to compete. The agreement is renewable for a one-year term after
the original term of two years.

(16) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used to estimate the fair value
of financial instruments:
 
     Cash and due from banks.  The carrying amount is a reasonable estimate of
fair value.
 
     Federal funds and investment securities.  For federal funds sold and other
short-term investments, the carrying amount is a reasonable estimate of fair
value. U.S. government and agency obligations, state, county and municipal
securities and other investments are valued using quoted market prices.
 
     Loans receivable.  For demand loans, the carrying value is a reasonable
estimate of fair value. Fair value of other loans is estimated by discounting
estimated future cash flows using the current rates at which similar loans are
being offered by the Bank.
 
     Deposit accounts.  The fair value of demand deposits is the amount payable
on demand at the reporting date. The fair value of certificates of deposit is
estimated by discounting future cash flows using the rates currently offered for
deposits with similar remaining maturities.
 
     The fair value estimates were made at a discrete point in time based on
relevant market information and information about the financial instruments.
Because no market exists for a significant portion of the financial instruments,
fair value estimates were based on judgments regarding future expected loss
experience, current economic conditions, risk characteristics of various
financial instruments, and other factors. These estimates were subjective in
nature and involved uncertainties and matters of significant judgment and
therefore cannot be determined with precision. Changes in assumptions could
significantly affect the estimates.
 
     The fair value estimates were based on existing on-balance sheet and
off-balance sheet financial instruments without attempting to estimate the value
of anticipated future business and the value of assets and liabilities that were
not considered financial instruments. Other significant assets that were not
considered financial instruments included deferred tax assets, other assets, and
property and equipment. The tax effects related to the realization of the
unrealized gains and losses on investment securities can have a significant
impact on fair value estimates and were not considered in the estimates.

(17) REGULATORY CAPITAL REQUIREMENTS
 
     The Bank is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory, and possibly additional discretionary, actions
by regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance-sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings, and other factors.
 
     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to average
assets (as defined). Management believes, as of December 31, 1996, that the Bank
meets all capital adequacy requirements to which it is subject.
 
     As of March 31, 1996, the most recent notification from the Federal Deposit
Insurance Corporation categorized the Bank as well capitalized under the
regulatory framework for prompt corrective action. To be categorized as well
capitalized, the Bank must maintain minimum total risk-based, Tier I risk-based,
Tier I leverage ratios as set forth in the table. There are no conditions or
events since that notification that management believes have changed the
institution's category.
 
     The Bank's actual capital amounts and ratios are also presented in the
table. No amounts were deducted from capital for interest-rate risk.

Alabama, Florida, Georgia and Tennessee; and

rights of property, franchises and interests, including appointments,
designations and nominations and all other rights and interests as trustee,
executor, administrator, transfer agent and registrar of stocks and bonds,

Corporation and BancGroup, respectively, on the Effective Date.
 
                                       A-1
<PAGE>   120
 
     2.3 Articles of Incorporation and Bylaws.  On the Effective Date, the
certificate of incorporation and bylaws of the Resulting Corporation shall be
the restated certificate of incorporation and bylaws of BancGroup as they exist
immediately before the Effective Date.
 
     2.4 Resulting Corporation's Officers and Board.  The board of directors and
the officers of the Resulting Corporation on the Effective Date shall consist of
those persons serving in such capacities of BancGroup as of the Effective Date.
 
     2.5 Stockholder Approval.  This Agreement shall be submitted to the
shareholders of Acquired Corporation at the Stockholders Meeting to be held as
promptly as practicable consistent with the satisfaction of the conditions set
forth in this Agreement. Upon approval by the requisite vote of the shareholders
of Acquired Corporation as required by applicable Law, the Merger shall become
effective as soon as practicable thereafter in the manner provided in section
2.7 hereof.
 
     2.6 Further Acts.  If, at any time after the Effective Date, the Resulting
Corporation shall consider or be advised that any further assignments or
assurances in law or any other acts are necessary or desirable (i) to vest,
perfect, confirm or record, in the Resulting Corporation, title to and
possession of any property or right of Acquired Corporation or BancGroup,
acquired as a result of the Merger, or (ii) otherwise to carry out the purposes
of this Agreement, BancGroup and its officers and directors shall execute and
deliver all such proper deeds, assignments and assurances in law and do all acts
necessary or proper to vest, perfect or confirm title to, and possession of,
such property or rights in the Resulting Corporation and otherwise to carry out
the purposes of this Agreement; and the proper officers and directors of the
Resulting Corporation are fully authorized in the name of Acquired Corporation
or BancGroup, or otherwise, to take any and all such action.

of Law and the conditions specified in this Agreement, the Merger shall become
effective on the date specified in the Certificate of Merger to be issued by the
Secretary of State of the State of Delaware (such time being herein called the

will be satisfied as of the Closing, the Closing shall take place at the offices
of BancGroup, in Montgomery, Alabama, at 11:00 a.m. on a date specified by
BancGroup that shall be as soon as reasonably practicable after the later to
occur of the Stockholder Meeting or all required regulatory approvals under
Section 8.2, or at such other place and time that the Parties may mutually
agree.
 
     2.8 Subsidiary Bank Merger.  BancGroup and Acquired Corporation anticipate
that immediately after the Effective Date the Bank will merge with and into
Colonial Bank, BancGroup's Florida Subsidiary bank. The exact timing and
structure of such merger are not known at this time, and BancGroup in its
discretion will finalize such timing and structure at a later date. Acquired
Corporation will cooperate with BancGroup, including the call of any special
meetings of the board of directors of the Bank and the filing of any regulatory
applications, in the execution of appropriate documentation relating to such
merger, including the taking of any action required by section 3.1(e) hereof.
 
                                   ARTICLE 3
 
                    CONVERSION OF ACQUIRED CORPORATION STOCK
 
     3.1 Conversion of Acquired Corporation Stock.  (a) On the Effective Date,
each share of common stock of Acquired Corporation outstanding and held by
Acquired Corporation's shareholders (the "Acquired Corporation Stock"), shall be
converted by operation of law and without any action by any holder thereof into
shares of BancGroup Common Stock (the "Merger Consideration") at the rate of
 .4326 of a share of BancGroup Common Stock for each share of Acquired
Corporation Stock, provided that the Market Value for BancGroup is not less than
$19.35 and not greater than $25.16. If the Market Value is less than $19.35,
then each share of Acquired Corporation Stock outstanding at the Effective Date
shall be converted into the number of shares of BancGroup Common Stock that
shall equal $8.37 divided by the Market Value. If the Market Value is greater
than $25.16, then each share of Acquired Corporation Stock shall be converted
into such number of shares of BancGroup Common Stock that shall equal $10.88
divided by the Market Value, subject to section 3.1(d) below. The appropriate
ratio that is used to calculate the Merger Consideration based
 
                                       A-2
<PAGE>   121
 
upon the Market Value as set forth above is referred to as the "Exchange Ratio."
For these purposes, the "Market Value" shall represent the per share market
value of the BancGroup Common Stock at the Effective Date and shall be
determined by calculating the average of the closing prices of the Common Stock
of BancGroup as reported by the NYSE on each of the ten consecutive trading days
ending on the trading day five calendar days preceding the Effective Date. As of
the date hereof, there are 1,585,737 shares of Acquired Corporation Stock
outstanding. To the extent that the number of shares of Acquired Corporation
Stock may increase based upon the exercise of Acquired Corporation Options or
the exercise of Acquired Corporation warrants, the number of shares of BancGroup
Common Stock to be issued in the Merger shall be increased with each share of
Acquired Corporation Stock outstanding at the Effective Date exchanged for
shares of BancGroup Common Stock at the Exchange Ratio.
 
     (b)(i) On the Effective Date, BancGroup shall assume all Acquired
Corporation Options outstanding, and each such option shall cease to represent a
right to acquire Acquired Corporation common stock and shall, instead, represent
the right to acquire BancGroup Common Stock on substantially the same terms
applicable to the Acquired Corporation Options except as specified below in this
section. The number of shares of BancGroup Common Stock to be issued pursuant to
such options shall equal the number of shares of Acquired Corporation common
stock subject to such Acquired Corporation Options multiplied by the Exchange
Ratio, provided that no fractions of shares of BancGroup Common Stock shall be
issued and the number of shares of BancGroup Common Stock to be issued upon the
exercise of Acquired Corporation Options, if a fractional share exists, shall
equal the number of whole shares obtained by rounding to the nearest whole
number, giving account to such fraction, or by paying for such fraction in cash,
based upon the Market Value. The exercise price for the acquisition of BancGroup
Common Stock shall be the exercise price for each share of Acquired Corporation
common stock subject to such options divided by the Exchange Ratio, adjusted
appropriately for any rounding to whole shares that may be done. It is intended
that the assumption by BancGroup of the Acquired Corporation Options shall be
undertaken in a manner that will not constitute a "modification" as defined in
Section 424 of the Code as to any stock option which is an "incentive stock
option." Schedule 3.1 hereto sets forth the names of all persons holding
Acquired Corporation Options, the number of shares of Acquired Corporation
common stock subject to such options, the exercise price and the expiration date
of such options.
 
     (ii) In lieu of the foregoing section 3.1(b)(i), and at the election of
holders of Acquired Corporation Options, BancGroup shall pay at the Closing a
sum in cash equal to the difference between the exercise price of Acquired
Corporation Options and the value of such options using the Market Value to
calculate the value of such options based upon the Exchange Ratio. Any Holder of
such options may notify BancGroup in writing at any time prior to the Closing of
his or her election to receive such cash.
 
     (iii) BancGroup shall file at its expense a registration statement with the
SEC on Form S-8 (including the Form S-4 to be filed in connection with the
Merger) with respect to the shares of BancGroup Common Stock to be issued
pursuant to Acquired Corporation Options and pursuant to the Acquired
Corporation warrants assumed under section 3.1(c), and shall use its reasonable
best efforts to maintain the effectiveness of such registration statement for so
long as such options or warrants remain outstanding. Such shares shall also be
registered or qualified for sale under the securities laws of any state in which
registration or qualification is necessary.
 
     (c) (i) On the Effective Date, BancGroup will assume Acquired Corporation's
warrants respecting the issuance of 140,716 shares of Acquired Corporation
Stock. Such warrants shall be exercisable for shares of BancGroup Common Stock,
with each share of Acquired Corporation Stock that would have been issued upon
exercise of such warrant being convertible into such number of shares of
BancGroup Common Stock equal to one share of Acquired Corporation common stock
multiplied by the Exchange Ratio and with the exercise price for such warrants
divided by the Exchange Ratio. No fractions of shares of BancGroup Common Stock
will be issued upon conversion and exercise of such warrants, and if a fraction
exists, such fraction shall be rounded to the nearest whole number or shall be
paid in cash based upon the Market Value.
 
     (ii) In lieu of the foregoing Section 3.1(c)(i), and at the election of
holders of such warrants, BancGroup shall pay at the Closing a sum in cash equal
to the difference between the exercise price of such
 
                                       A-3
<PAGE>   122
 
warrants and the value of such warrants using the Market Value to calculate the
value of such warrants based upon the Exchange Ratio. Any Holder of such
warrants may notify BancGroup in writing at any time prior to the Closing of his
or her election to receive such cash.
 
     (d) If BancGroup publicly announces prior to the Effective Date that is has
entered into an agreement pursuant to which BancGroup will be acquired through a
merger, sale of assets of BancGroup or tender offer or exchange offer for
BancGroup common stock (or otherwise), then the Exchange Ratio shall be
determined for all purposes of this Agreement by disregarding whether the Market
Value is greater than $25.16. Any merger in which BancGroup is the surviving
corporation that does not involve a change of control of BancGroup shall be
excluded from the preceding sentence. For this purpose a "change of control"
means the acquisition of beneficial ownership of the common stock of BancGroup
by any person or group (as that term is defined under section 13(d) of the 1934
Act) of more than 50 percent of the outstanding shares of such stock.
 
     (e) There are currently 600 shares of outstanding common stock of the Bank
that are held by shareholders other than Acquired Corporation. Prior to the
Effective Date, Acquired Corporation and Colonial Bank, BancGroup's bank
subsidiary in Florida, will enter into a merger agreement providing for a merger
of the Bank with Colonial Bank following consummation of the Merger pursuant to
the provisions of the Florida Banking Code and the Alabama Banking Code, as
applicable. It is the intention of the Parties that on the Effective Date, and
following the Closing, the Bank will be merged with Colonial Bank and that cash
will be paid to such shareholders in an amount per share equal to the per share
Merger Consideration received by shareholders of Acquired Corporation.
 
     3.2 Surrender of Acquired Corporation Stock.  After the Effective Date,
each holder of an outstanding certificate or certificates which prior thereto
represented shares of Acquired Corporation Stock who is entitled to receive
BancGroup Common Stock shall be entitled, upon surrender to BancGroup of their
certificate or certificates representing shares of Acquired Corporation Stock
(or an affidavit or affirmation by such holder of the loss, theft, or
destruction of such certificate or certificates in such form as BancGroup may
reasonably require and, if BancGroup reasonably requires, a bond of indemnity in
form and amount, and issued by such sureties, as BancGroup may reasonably
require), to receive in exchange therefor a certificate or certificates
representing the number of whole shares of BancGroup Common Stock into and for
which the shares of Acquired Corporation Stock so surrendered shall have been
converted, such certificates to be of such denominations and registered in such
names as such holder may reasonably request. Until so surrendered and exchanged,
each such outstanding certificate which, prior to the Effective Date,
represented shares of Acquired Corporation Stock and which is to be converted
into BancGroup Common Stock shall for all purposes evidence ownership of the
BancGroup Common Stock into and for which such shares shall have been so
converted, except that no dividends or other distributions with respect to such
BancGroup Common Stock shall be made until the certificates previously
representing shares of Acquired Corporation Stock shall have been properly
tendered.
 
     3.3 Fractional Shares.  No fractional shares of BancGroup Common Stock
shall be issued, and each holder of shares of Acquired Corporation Stock having
a fractional interest arising upon the conversion of such shares into shares of
BancGroup Common Stock shall, at the time of surrender of the certificates
previously representing Acquired Corporation Stock, be paid by BancGroup an
amount in cash equal to the Market Value of such fractional share.
 
     3.4 Adjustments.  In the event that prior to the Effective Date BancGroup
Common Stock shall be changed into a different number of shares or a different
class of shares by reason of any recapitalization or reclassification, stock
dividend, combination, stock split, or reverse stock split of the BancGroup
Common Stock, an appropriate and proportionate adjustment shall be made in the
number of shares of BancGroup Common Stock into which the Acquired Corporation
Stock shall be converted.
 
     3.5 BancGroup Stock.  The shares of Common Stock of BancGroup issued and
outstanding immediately before the Effective Date shall continue to be issued
and outstanding shares of the Resulting Corporation.

not have voted in favor of this Agreement and who has complied with the
applicable procedures set forth in the FBCA, relating to rights of dissenting
shareholders, shall be entitled to receive payment for the fair value of his
Acquired Corporation Stock. If after the Effective Date a dissenting shareholder
of Acquired Corporation fails to perfect, or effectively withdraws or loses, his
right to appraisal and payment for his shares of Acquired Corporation Stock,
BancGroup shall issue and deliver the consideration to which such holder of
shares of Acquired Corporation Stock is entitled under Section 3.1 (without
interest) upon surrender of such holder of the certificate or certificates
representing shares of Acquired Corporation Stock held by him.

     BancGroup represents, warrants and covenants to and with Acquired
Corporation as follows:
 
     4.1 Organization.  BancGroup is a corporation duly organized, validly
existing and in good standing under the Laws of the State of Delaware. BancGroup
has the necessary corporate powers to carry on its business as presently
conducted and is qualified to do business in every jurisdiction in which the
character and location of the Assets owned by it or the nature of the business
transacted by it requires qualification or in which the failure to qualify
could, individually or in the aggregate, have a Material Adverse Effect.
 
     4.2 Capital Stock.  (a) The authorized capital stock of BancGroup consists
of (A) 44,000,000 shares of Common Stock, $2.50 par value per share, of which as
of February 14, 1997, 38,880,014 shares were validly issued and outstanding,
fully paid and nonassessable and are not subject to preemptive rights (not
counting additional shares subject to issue pursuant to stock option and other
plans and convertible debentures), and (B) 1,000,000 shares of Preference Stock,
$2.50 par value per share, none of which are issued and outstanding. The shares
of BancGroup Common Stock to be issued in the Merger are duly authorized and,
when so issued, will be validly issued and outstanding, fully paid and
nonassessable, will have been registered under the 1933 Act, and will have been
registered or qualified under the securities laws of all jurisdictions in which
such registration or qualification is required, based upon information provided
by Acquired Corporation.
 
     (b) The authorized capital stock of each Subsidiary of BancGroup is validly
issued and outstanding, fully paid and nonassessable, and each Subsidiary is
wholly owned, directly or indirectly, by BancGroup.
 
     4.3 Financial Statements; Taxes.  (a) BancGroup has delivered to Acquired
Corporation copies of the following financial statements (as restated) of
BancGroup:
 
          (i) Consolidated balance sheets as of December 31, 1994, and December
     31, 1995, and for the nine months ended September 30, 1996;
 
          (ii) Consolidated statements of operations for each of the three years
     ended December 31, 1993, 1994 and 1995, and for the nine months ended
     September 30, 1996;
 
          (iii) Consolidated statements of cash flows for each of the three
     years ended December 31, 1993, 1994 and 1995, and for the nine months ended
     September 30, 1996; and
 
          (iv) Consolidated statements of changes in shareholders' equity for
     the three years ended December 31, 1993, 1994 and 1995, and for the nine
     months ended September 30, 1996.
 
     All such financial statements are in all material respects in accordance
with the books and records of BancGroup and have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
throughout the periods indicated, all as more particularly set forth in the
notes to such statements. Each of the consolidated balance sheets presents
fairly as of its date the consolidated financial condition of BancGroup and its
Subsidiaries. Except as and to the extent reflected or reserved against in such
balance sheets (including the notes thereto), BancGroup did not have, as of the
dates of such balance sheets, any material Liabilities or obligations (absolute
or contingent) of a nature customarily reflected in a balance sheet or the notes
thereto. The statements of consolidated income, shareholders' equity and changes
in consolidated financial position present fairly the results of operations and
changes in financial position of
 
                                       A-5
<PAGE>   124

accurate in all material respects. All Taxes shown on these returns to be due
and all additional assessments received have been paid. The amounts recorded for
Taxes on the balance sheets provided under section 4.3(a) are, to the Knowledge

all Tax withholding provisions of applicable federal, state, foreign and local
Laws (including without limitation, income, social security and employment Tax
withholding for all types of compensation).
 
     4.4 No Conflict with Other Instrument.  The consummation of the
transactions contemplated by this Agreement will not result in a breach of or
constitute a Default (without regard to the giving of notice or the passage of
time) under any material Contract, indenture, mortgage, deed of trust or other
material agreement or instrument to which BancGroup or any of its Subsidiaries
is a party or by which they or their Assets may be bound; will not conflict with
any provision of the restated certificate of incorporation or bylaws of

the matters referred to in section 8.2, BancGroup has full power, authority and
legal right to enter into this Agreement and to consummate the transactions

material delays.

dispose of any of the Assets of Acquired Corporation, subsequent to the Merger,
and BancGroup intends to continue the historic business of Acquired Corporation.
 
     4.8 Title and Related Matters.  BancGroup has good and marketable title to
all the properties, interests in properties and Assets, real and personal,
reflected in the most recent balance sheet referred to in section 4.3(a), or
acquired after the date of such balance sheet (except properties, interests and

business), free and clear of all mortgages, Liens, pledges, charges or
encumbrances except (i) mortgages and other encumbrances referred to in the

and is validly existing as a corporation in good standing under the Laws of the
jurisdiction of its incorporation and each Subsidiary has been duly qualified as
a foreign corporation to transact business and is in good standing under the
Laws of each other jurisdiction in which it owns or leases properties, or

Subsidiaries of BancGroup has its deposits fully insured by the Federal Deposit
Insurance Corporation to the extent provided by the Federal Deposit Insurance
Act; and the businesses of the non-bank Subsidiaries of BancGroup are permitted

Default in any material respect under the terms of any material Contract,
agreement, lease or other commitment which is or may be material to the
business, operations, properties or Assets, or the condition, financial or
otherwise, of such company and, to the Knowledge of BancGroup, there is no event
which, with notice or lapse of time, or both, may be or become an event of
Default under any such material Contract, agreement, lease or other commitment
in respect of which adequate steps have not been taken to prevent such a Default
from occurring.
 
     4.11 Litigation.  Except as disclosed in or reserved for in BancGroup's
financial statements, there is no Litigation before or by any court or Agency,
domestic or foreign, now pending, or, to the Knowledge of BancGroup, threatened

therein), or which may have any Material Adverse Effect or prospective Material
Adverse Effect, or which is likely to materially and adversely affect the

legal or governmental proceedings to which BancGroup or any Subsidiary is a
party or of which any of their properties is the subject which are not described
in the Registration Statement, including ordinary routine litigation incidental
to the business, are, considered in the aggregate, not material; and neither
BancGroup nor any of its Subsidiaries have any contingent obligations which

its Subsidiaries has complied in all material respects with all material
applicable Laws and Regulations including those imposing Taxes, of any

material federal, state or local Laws applicable to their or the conduct of
their businesses.

     (a) Title.  Acquired Corporation has good and marketable title to all the

material respects with the requirements of all applicable Laws.

department, commission, board, bureau, agency or instrumentality, domestic or
foreign, or before any arbitrator of any kind, which involves the possibility of
any judgment or Liability not fully covered by insurance in excess of a
reasonable deductible amount or which may have a Material Adverse Effect on
Acquired Corporation, and no Acquired Corporation Company is in Default with
respect to any judgment, order, writ, injunction, decree, award, rule or
regulation of any court, arbitrator or governmental department, commission,
board, bureau, agency or instrumentality, which Default would have a Material
Adverse Effect on Acquired Corporation. To the Knowledge of Acquired
Corporation, each Acquired Corporation Company has complied in all material
respects with all material applicable Laws and Regulations including those
imposing Taxes, of any applicable jurisdiction and of all states,
municipalities, other political subdivisions and Agencies, in respect of the
ownership of its properties and the conduct of its business, which, if not
complied with, would have a Material Adverse Effect on Acquired Corporation.
 
     5.10 Material Contract Defaults.  Except as disclosed on Schedule 5.10, no
Acquired Corporation Company is in Default in any material respect under the
terms of any material Contract, agreement, lease or other commitment which is or
may be material to the business, operations, properties or Assets, or the
condition, financial or otherwise, of such company and, to the Knowledge of
Acquired Corporation, there is no event which, with notice or lapse of time, or
both, may be or become an event of Default under any such material Contract,
agreement, lease or other commitment in respect of which adequate steps have not
been taken to prevent such a Default from occurring.
 
     5.11 No Conflict with Other Instrument.  The consummation of the
transactions contemplated by this Agreement will not result in the breach of any
term or provision of or constitute a Default under any material Contract,
indenture, mortgage, deed of trust or other material agreement or instrument to
which any Acquired Corporation Company is a party and will not conflict with any
provision of the charter or bylaws of any Acquired Corporation Company.
 
     5.12 Governmental Authorization.  Each Acquired Corporation Company has all
Permits that, to the Knowledge of Acquired Corporation, are or will be legally
required to enable any Acquired Corporation Company to conduct its business in
all material respects as now conducted by each Acquired Corporation Company.
 
     5.13 Absence of Regulatory Communications.  Except as provided in Schedule
5.13, no Acquired Corporation Company is subject to, nor has any Acquired
Corporation Company received during the past three years, any written
communication directed specifically to it from any Agency to which it is subject

material restrictions on the operations of it or the business conducted by it or
in which such Agency has raised any material question concerning the condition,
financial or otherwise, of such company.
 
     5.14 Absence of Material Adverse Change.  To the Knowledge of Acquired
Corporation, since the date of the most recent balance sheet provided under

coverage and bonds with reputable insurers which, in respect to amounts, types
and risks insured, management of Acquired Corporation reasonably believes to be
adequate for the type of business conducted by such company. No Acquired
Corporation Company is liable for any material retroactive premium adjustment.
All insurance policies and
 
                                      A-12
<PAGE>   131
 
bonds are valid, enforceable and in full force and effect, and no Acquired
Corporation Company has received any notice of any material premium increase or
cancellation with respect to any of its insurance policies or bonds. Within the
last three years, no Acquired Corporation Company has been refused any insurance
coverage which it has sought or applied for, and it has no reason to believe
that existing insurance coverage cannot be renewed as and when the same shall
expire, upon terms and conditions as favorable as those presently in effect,
other than possible increases in premiums that do not result from any
extraordinary loss experience. All policies of insurance presently held or
policies containing substantially equivalent coverage will be outstanding and in
full force with respect to each Acquired Corporation Company at all times from
the date hereof to the Effective Date.
 
     5.16 Pension and Employee Benefit Plans.  (a) To the Knowledge of Acquired
Corporation, all employee benefit plans of each Acquired Corporation Company
have been established in compliance with, and such plans have been operated in
material compliance with, all applicable Laws. Except as set forth in Schedule
5.16, no Acquired Corporation Company sponsors or otherwise maintains a "pension
plan" within the meaning of section 3(2) of ERISA or any other retirement plan
other than the 401(k) plan of Acquired Corporation that is intended to qualify
under section 401 of the Code, nor do any unfunded Liabilities exist with
respect to any employee benefit plan, past or present. To the Knowledge of
Acquired Corporation, no employee benefit plan, any trust created thereunder or
any trustee or administrator thereof has engaged in a "prohibited transaction,"
as defined in section 4975 of the Code, which may have a Material Adverse Effect
on the condition, financial or otherwise, of any Acquired Corporation Company.
 
     (b) To the Knowledge of Acquired Corporation, no amounts payable to any
employee of any Acquired Corporation Company will fail to be deductible for
federal income tax purposes by virtue of Section 280G of the Code and
regulations thereunder.
 
     5.17 Buy-Sell Agreement.  To the Knowledge of Acquired Corporation, there
are no agreements among any of its shareholders granting to any person or
persons a right of first refusal in respect of the sale, transfer, or other
disposition of shares of outstanding securities by any shareholder of Acquired
Corporation, any similar agreement or any voting agreement or voting trust in
respect of any such shares.
 
     5.18 Brokers.  Except for services provided by T. Stephen & Johnson and
Associates, Inc., and Austin Associates, Inc., all negotiations relative to this
Agreement and the transactions contemplated by this Agreement have been carried
on by Acquired Corporation directly with BancGroup and without the intervention
of any other person, either as a result of any act of Acquired Corporation, or
otherwise, in such manner as to give rise to any valid claim against Acquired
Corporation for a finder's fee, brokerage commission or other like payment.
 
     5.19 Approval of Agreements.  The board of directors of Acquired
Corporation has approved this Agreement and the transactions contemplated by
this Agreement and has authorized the execution and delivery by Acquired
Corporation of this Agreement. Subject to the matters referred to in section
8.2, Acquired Corporation has full power, authority and legal right to enter

certificate furnished or to be furnished to BancGroup by Acquired Corporation,
contains or will contain any untrue statement of a material fact, or omits or
will omit to state a material fact necessary to make the statements contained in
this Agreement or in any such statement or certificate not misleading.
 
     5.21 Registration Statement.  At the time the Registration Statement
becomes effective and at the time of the Stockholders Meeting, the Registration
Statement, including the Proxy Statement which shall constitute part thereof,
will not contain an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading; provided, however,
that the representations and warranties in this section shall only apply to
statements in or omissions from the Proxy Statement relating to descriptions of
the business of

representatives expressly for inclusion in the Proxy Statement.
 
     5.22 Loans; Adequacy of Allowance for Loan Losses.  All reserves for loan
losses shown on the most recent financial statements furnished by Acquired
Corporation have been calculated in accordance with prudent and customary
banking practices and are adequate in all material respects to reflect the risk
inherent in the loans of Acquired Corporation. Acquired Corporation has no
Knowledge of any fact which is likely to require a future material increase in
the provision for loan losses or a material decrease in the loan loss reserve
reflected in such financial statements. Each loan reflected as an Asset on the
financial statements of Acquired Corporation is the legal, valid and binding
obligation of the obligor of each loan, enforceable in accordance with its terms
subject to the effect of bankruptcy, insolvency, reorganization, moratorium, or
other similar laws relating to creditors' rights generally and to general
equitable principles. Acquired Corporation does not have in its portfolio any

Knowledge of Acquired Corporation, each Acquired Corporation Company is in
material compliance with all Laws and other governmental requirements relating
to the generation, management, handling, transportation, treatment, disposal,
storage, delivery, discharge, release or emission of any waste, pollution, or
toxic, hazardous or other substance (the "Environmental Laws"), and Acquired
Corporation has no Knowledge that any Acquired Corporation Company has not
complied with all regulations and requirements promulgated by the Occupational
Safety and Health Administration that are applicable to any Acquired Corporation
Company. To the Knowledge of Acquired Corporation, there is no Litigation

any substances for which the appropriate remedial action has not been completed;
(ii) no owned or leased property is contaminated with or contains any hazardous
substance or waste; and (iii) there are no underground storage tanks on any
premises owned or leased by any Acquired Corporation Company. Acquired
Corporation has no Knowledge of any facts which might suggest that any Acquired
Corporation Company has engaged in any management practice with respect to any
of its past or existing borrowers which could reasonably be expected to subject
any Acquired Corporation Company to any Liability, either directly or
indirectly, under the principles of law as set forth in United States v. Fleet
Factors Corp., 901 F.2d 1550 (11th Cir. 1990) or any similar principles.
Moreover, to the Knowledge of Acquired Corporation, no Acquired Corporation
Company has extended credit, either on a secured or unsecured basis, to any
person or other entity engaged in any activities which would require or requires
such person or entity to obtain any Permits which are required under any
Environmental Law which has not been obtained.
 
     5.24 Transfer of Shares.  Acquired Corporation has no Knowledge of any plan
or intention on the part of Acquired Corporation's shareholders to sell or
otherwise dispose of any of the BancGroup Common Stock to be received by them in
the Merger that would reduce such shareholders' ownership to a number of shares
having, in the aggregate, a fair market value of less than fifty (50%) percent
of the total fair market value of Acquired Corporation common stock outstanding
immediately before the Merger.

bargaining agreements, letters of undertakings or other arrangements, formal or
informal, between any Acquired Corporation Company and any union or labor
organization covering any of Acquired Corporation Company's employees and none

of employment, wages and hours. No Acquired Corporation Company is or has been
engaged in any unfair labor practice, and, to the Knowledge of Acquired
Corporation, no unfair labor practice complaint against any Acquired Corporation
Company is pending before the National Labor Relations Board. Relations between
management of each Acquired Corporation Company and the employees
 
                                      A-14
<PAGE>   133
 
are amicable and there have not been, nor to the Knowledge of Acquired
Corporation, are there presently, any attempts to organize employees, nor to the
Knowledge of Acquired Corporation, are there plans for any such attempts.

or has agreed to enter into a swap, forward, future, option, cap, floor or
collar financial contract, or any other interest rate or foreign currency
protection contract or derivative security not included in Acquired
Corporation's financial statements delivered under section 5.4 hereof which is a

        days after the end of each quarterly period (other than the last

          (e) Listing.  Prior to the Effective Date, BancGroup shall use its
     reasonable efforts to list the shares of BancGroup Common Stock to be
     issued in the Merger on the NYSE or other quotations system on which such
     shares are primarily traded.
 
          (f) Employee Benefit Matters.  On the Effective Date, all employees of
     any Acquired Corporation Company shall, at BancGroup's option, either
     become employees of the Resulting Corporation or its Subsidiaries or be
     entitled to severance benefits in accordance with Colonial Bank's severance
     policy as of the date of this Agreement. All employees of any Acquired
     Corporation Company who become employees of the Resulting Corporation or
     its Subsidiaries on the Effective Date shall be entitled, to the extent
     permitted by applicable Law, to participate in all benefit plans of
     Colonial Bank to the same extent as Colonial Bank employees, except as
     stated otherwise in this section. Employees of any Acquired Corporation
     Company who become employees of the Resulting Corporation or its
     Subsidiaries on the Effective Date shall be allowed to participate as of
     the Effective Date in the medical and dental benefits plan of Colonial Bank
     as new employees of Colonial Bank, and the time of employment of such
     employees who are employed at least 30 hours per week with any Acquired
     Corporation Company as of the Effective Date shall be counted as employment
     under such dental and medical plans of Colonial Bank for purposes of
     calculating any 30 day waiting period and pre-existing condition
     limitations. To the extent permitted by applicable Law, the period of
     service with the appropriate Acquired Corporation Company of all employees
     who become employees of the Resulting Corporation or its Subsidiaries on
     the Effective Date shall be recognized only for vesting and eligibility
     purposes under Colonial Bank's benefit plans. In addition, if the Effective
     Date falls within an annual period of coverage under any group health plan
     or group dental plan of the Resulting Corporation and its Subsidiaries,
     each such Acquired Corporation Company employee shall be given credit for
     covered expenses paid by that employee under comparable employee benefit
     plans of the Acquired Corporation Company during the applicable coverage
     period through the Effective Date towards satisfaction of any annual
     deductible limitation and out-of-pocket maximum that may apply under that
     group health plan or group dental plan of the Resulting Corporation and its
     Subsidiaries.
 
          (g) Indemnification.  (i) Subject to the conditions set forth in the
     succeeding paragraph, for a period of six years after the Effective Date
     BancGroup shall, and shall cause Colonial Bank to, indemnify, defend and
     hold harmless each person entitled to indemnification from the Acquired
     Corporation (each being an "Indemnified Party") against all liabilities
     arising out of actions or omissions occurring upon or prior to the
     Effective Date (including without limitation the transactions contemplated
     by this Agreement) to the extent authorized under the articles of
     incorporation and bylaws of Acquired Corporation and Florida law.
 
             (ii) Any Indemnified Party wishing to claim indemnification under
        this subsection (g), upon learning of any such liability or Litigation,
        shall promptly notify BancGroup thereof. In the event of any such
        Litigation (whether arising before or after the Effective Date) (i)
        BancGroup or Colonial Bank shall have the right to assume the defense
        thereof with counsel reasonably acceptable to such Indemnified Party
        and, upon assumption of such defense, BancGroup shall not be liable to
        such Indemnified Parties for any legal expenses of other counsel or any
        other expenses subsequently incurred by such Indemnified Parties in
        connection with the defense thereof, except that if BancGroup or
        Colonial Bank elects not to assume such defense or counsel for the
        Indemnified Parties advises that there are substantive issues which
        raise conflicts of interest between BancGroup and the Indemnified
        Parties, the Indemnified Parties may retain counsel satisfactory to
        them, and BancGroup or Colonial Bank shall pay all reasonable fees and
        expenses of such counsel for the Indemnified Parties promptly as
        statements therefor are received; provided, that BancGroup shall be
        obligated pursuant to this subsection to pay for only one firm of
        counsel for all Indemnified Parties in any jurisdiction, (ii) the
        Indemnified Parties will cooperate in the defense of any such
        Litigation; and (iii) BancGroup shall not be liable for any settlement
        effected without its prior consent; and provided further that BancGroup
        and Colonial Bank shall not have any obligation hereunder to any
        Indemnified Party when and if a court of competent jurisdiction shall
        determine, and such
 
                                      A-16
<PAGE>   135
 
        determination shall have become final, that the indemnification of such
        Indemnified Party in the manner contemplated hereby is prohibited by
        applicable Law.
 
             (iii) In consideration of and as a condition precedent to the
        effectiveness of the indemnification obligations provided by BancGroup
        in this section to a director or officer of the Acquired Corporation,
        such director or officer of the Acquired Corporation shall have
        delivered to BancGroup on or prior to the Effective Date a letter in
        form reasonably satisfactory to BancGroup concerning claims such
        directors or officers may have against Acquired Corporation. In the
        letter, the directors or officers shall: (i) acknowledge the assumption
        by BancGroup as of the Effective Date of all Liability (to the extent
        Acquired Corporation is so liable) for claims for indemnification
        arising under section 6.1(g) hereof; (ii) affirm that they do not have
        nor are they aware of any claims they might have (other than those
        referred to in the following clause (iii)) against Acquired Corporation;
        (iii) identify any claims or any facts or circumstances of which they
        are aware that could give rise to a claim for indemnification under
        section 6.1(g)(i) hereof; and (iv) release as of the Effective Date any
        and all claims that they may have against any Acquired Corporation
        Company other than (A) those referred to in the foregoing clause (iii)
        and disclosed in the letter of the director or officer, (B) claims by
        third parties which have not yet been asserted against such director or
        officer (other than claims arising from facts and circumstances of which
        such director or officer is aware but which are not disclosed in such
        director or executive officer's letter), (C) claims by third parties
        arising from any transaction contemplated by this Agreement or disclosed

     Corporation, or if any such negotiations or discussions are sought to be
     initiated with Acquired Corporation, and Acquired Corporation shall

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without

April   , 1997
 
Board of Directors
First Commerce Banks of Florida, Inc.
141 Central Avenue East
Winter Haven, FL 33880
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to First Commerce Banks of Florida, Inc. ("First Commerce") and its
shareholders of the terms of the Agreement and Plan of Merger dated March 24,
1997 ("Agreement") by and among First Commerce and The Colonial BancGroup, Inc.
("BancGroup"). The terms of the Agreement provide for the merger of First
Commerce with and into BancGroup.
 
     The terms of the Agreement provide for an Exchange Ratio of 0.4326 shares
of BancGroup Common Stock for each outstanding share of First Commerce, provided
that the Market Value (as defined in the Agreement) of BancGroup is not less
than $19.35 and nor more than $25.16 per share. This corresponds to per share
consideration for each First Commerce share of between $8.37 and $10.88. If the
Market Value of BancGroup is less than $19.35, the Exchange Ratio shall be
increased to provide for a minimum per share consideration of $8.37 for each
First Commerce share. If the Market Value of BancGroup is greater than $25.16,
the Exchange Ratio shall be decreased to provide for a maximum per share
consideration of $10.88 for each First Commerce share. If BancGroup publicly
announces prior to the Effective Date that it has entered into an agreement
pursuant to which it will be acquired, the Exchange Ratio shall be determined by
disregarding whether the Market Value is greater than $25.16 per share.
BancGroup will pay cash for fractional shares. The Agreement further provides
that BancGroup shall assume all First Commerce options and warrants adjusted for
the Exchange Ratio.
 
     In carrying out our engagement, we have reviewed and analyzed material
bearing upon the financial and operating condition of First Commerce and
BancGroup, including but not limited to the following: (i) the Proxy Statement
and Prospectus; (ii) the financial statements of First Commerce and BancGroup
for the period 1992 through 1996; (iii) certain other publicly available
information regarding First Commerce and BancGroup; (iv) publicly available
information regarding the performance of certain other companies whose business
activities were believed by Austin Associates to be generally comparable to
those of First Commerce and BancGroup; (v) the financial terms, to the extent
publicly available, of certain comparable transactions; and (vi) such other
analysis and information as we deemed relevant.
 
     In our review and analysis, we relied upon and assumed the accuracy and
completeness of the financial and other information provided to us or publicly
available, and have not attempted to verify the same. We have made no
independent verification as to the status of individual loans made by First
Commerce or BancGroup, and have instead relied upon representations and
information concerning loans of First Commerce and BancGroup in the aggregate.
In rendering our opinion, we have assumed that the transaction will be a
tax-free reorganization with no material adverse tax consequences to First
Commerce or BancGroup, or to First Commerce shareholders receiving BancGroup
stock. In addition, we have assumed in the course of obtaining the necessary
regulatory approvals for the transaction, no condition will be imposed that will
have a material adverse effect on the contemplated benefits of the transaction
to First Commerce and its shareholders.
 
     Based upon our analysis and subject to the qualifications described herein,
we believe that as of the date of this letter, the terms of the Agreement are
fair, from a financial point of view, to First Commerce and its shareholders.
 
     For our services in rendering this opinion, First Commerce will pay us a
fee and indemnify us against certain liabilities.

     plan by which all or substantially all of the net proceeds of the sale will
     be distributed to the shareholders within 1 year after the date of sale;

        series of shares;
 
             3. Effecting an exchange, cancellation, or reclassification of any
        of his shares, when such exchange, cancellation, or reclassification

        accrued dividends or other arrearages in respect to such shares;
 
             4. Reducing the stated redemption price of any of his redeemable

adversely affected by the amendment.
 
     (3) A Shareholder may dissent as to less than all the shares registered in
his name. In that event, his rights shall be determined as if the shares as to
which he has dissented and his other shares were registered in the names of
different shareholders.
 
     (4) Unless the articles of incorporation otherwise provide, this section
does not apply with respect to a plan of merger or share exchange or a proposed
sale or exchange of property, to the holders of shares of any class or series
which, on the record date fixed to determine the shareholders entitled to vote
at the meeting of shareholders at which such action is to be acted upon or to
consent to any such action without a meeting, were either registered on a
national securities exchange or designated as a national market system security
on a interdealer quotation system by the National Association of Securities
Dealers, Inc., or held of record by not fewer than 2,000 shareholders.
 
     (5) A shareholder entitled to dissent and obtain payment for his shares
under this section may not challenge the corporate action creating his
entitlement unless the action is unlawful or fraudulent with respect to the
shareholder or the corporation.
 
     607.1320 PROCEDURE FOR EXERCISE OF DISSENTERS' RIGHTS. -- (1)(a) If a
proposed corporate section creating dissenters' rights under sec. 607.1320 is

     of his intent to demand payment for his shares if the proposed action is
     effectuated, and
 
          2. Not vote his shares in favor of the proposed action. A proxy or
     vote against the proposed action does not constitute such a notice of
     intent to demand payment.
 
     (b) If proposed corporate action creating dissenters' rights under
sec. 607.1302 is effectuated by written consent without a meeting, the
corporation shall deliver a copy of sec.sec. 607.1301, 607,1302, and 607.1320 to
each shareholder simultaneously with any request for his written consent or, if
such a request is not made, within 10 days after the date the corporation
received written consents without a meeting from the requisite number of
shareholders necessary to authorize the action.
 
     (2) Within 10 days after the shareholders' authorization date, the
corporation shall give written notice of such authorization or consent or
adoption of the plan of merger, as the case may be, to each shareholder who
filed a notice of intent to demand payment for his shares pursuant to paragraph
(1)(a) or, in the case of action authorized by written consent, to each
shareholder, excepting any who voted for, or consented in writing to, the
proposed action.
 
     (3) Within 20 days after the giving of notice to him, any shareholder who
elects to dissent shall file with the corporation a notice of such election,
stating his name and address, the number, classes, and series of shares. Any
shareholder failing to file such election to dissent within the period set forth
shall be bound by the terms of the proposed corporate action. Any shareholder
filing an election to dissent shall deposit his certificates for certificated
shares with the corporation simultaneously with the filing of the election to
dissent. The corporation may restrict the transfer of uncertificated shares from
the date the shareholder's election to dissent is filed with the corporation.
 
                                       C-2
<PAGE>   153
 
     (4) Upon filing a notice of election to dissent, the shareholder shall
thereafter be entitled only to payment as provided in this section and shall not
be entitled to vote or to exercise any other rights of a shareholder. A notice
of election may be withdrawn in writing by the shareholder at any time before an
offer is made by the corporation, as provided in subsection (5), to pay for his
shares. After such offer, no such notice of election may be withdrawn unless the
corporation consents thereto. However, the right of such shareholder to be paid
the fair value of his shares shall cease, and he shall be reinstated to have all
right of such shareholder to be paid the fair value of his shares shall cease,
and he shall be reinstated to have all his rights as a shareholder as of the
filing of his notice of election, including any intervening preemptive rights
and the right to payment of any intervening dividend or other distribution or,
if any such rights have expired or any such dividend or distribution other than
in cash has been completed, in lieu thereof, at the election of the corporation,
the fair value thereof in cash as determined by the board as of the time of such
expiration or completion, but without prejudice otherwise to any corporate
proceeding that may have been taken in the interim, if:
 
          (a) Such demand is withdrawn as provided in this section;
 
          (b) The proposed corporate action is abandoned or rescinded or the
     shareholders revoke the authority to effect such action;
 
          (c) No demand or petition for the determination of fair value by a
     court has been made or filed within the time provided in this section; or
 
          (d) A court of competent jurisdiction determines that such shareholder
     is not entitled to the relief provided by this section.
 
     (5) Within 10 days after the expiration of the period in which shareholders
may file their notices of election to dissent, or within 10 days after such
corporate action is effected, whichever is later (but in no case later than 90
days from the shareholders' authorization date), the corporation shall make a
written offer to each dissenting shareholder who has made demand as provided in
this section to pay an amount the corporation estimates to be the fair value for
such shares. If the corporate action has not been consummated before the
expiration of the 90-day period after the shareholders' authorization date, the
offer may be made conditional upon the consummation of such action. Such notice
and offer shall be accompanied by:
 
          (a) A balance sheet of the corporation, the shares of which the
     dissenting shareholder holds, as of the latest available date and not more
     than 12 months prior to the making of such offer; and
 
          (b) A profit and loss statement of such corporation for the 12-month
     period ended on the date of such balance sheet or, if the corporation was
     not in existence throughout such 12-month period, for the portion thereof
     during which it was in existence.
 
     (6) If within 30 days after the making of such offer any shareholder
accepts the same, payment for his shares shall be made within 90 days after the
making of such offer or the consummation of the proposed action, whichever is
later. Upon payment of the agreed value, the dissenting shareholder shall cease
to have any interest in such shares.
 
     (7) If the corporation fails to make such offer within the period specific
therefor in subsection (5) or if it makes the offer and any dissenting
shareholder or shareholders fail to accept the same within the period of 30 days
thereafter, then the corporation, within 30 days after receipt of written demand
from any dissenting shareholder given within 60 days after the date on which
such corporate action was effected, shall, or at its election at any time within
such period of 60 days may, file an action in any court of competent
jurisdiction in the county in this state where the registered office of the
corporation is located requesting that the fair value of such shares be
determined. The court shall also determine whether each dissenting shareholder,
as to whom the corporation requests the court to make such determination, is
entitled to receive payment for his shares. If the corporation fails to
institute the proceeding as herein provided, any dissenting shareholders
(whether or not residents of this state), other than shareholders who have
agreed with the corporation as to the value of their shares, shall be made
parties to the proceeding as an action against their shares. The corporation
shall serve a copy of the initial pleading in such proceeding upon each
dissenting shareholder who is a resident of
 
                                       C-3
<PAGE>   154
 
this state in the manner provided by law for the service of a summons and
complaint and upon each nonresident dissenting shareholder either by registered
or certified mail and publication or in such other manner as is permitted by
law. The jurisdiction of the court is plenary and exclusive. All shareholders
who are proper parties to the proceeding are entitled to judgment against the
corporation for the amount of the fair value of their shares. The court may, if
it so elects, appoint one or more persons as appraisers to receive evidence and
recommend a decision on the question of fair value. The appraisers shall have
such power and authority as is specified in the order of their appointment or an
amendment thereof. The corporation shall pay each dissenting shareholder the
amount found to be due him within 10 days after final determination of the
proceedings. Upon payment of the judgment, the dissenting shareholder shall
cease to have any interest in such shares.
 
     (8) The judgment may, at the discretion of the court, include a fair rate
of interest, to be determined by the court.
 
     (9) The costs and expenses of any such proceeding shall be determined by
the court and shall be assessed against the corporation, but all or any part of
such costs and expenses may be apportioned and assessed as the court deems
equitable against any or all of the dissenting shareholders who are parties to
the proceeding, to whom the corporation has made an offer to pay for the shares,
if the court finds that action of such shareholders in failing to accept such
offer was arbitrary, vexatious, or not in good faith. Such expenses shall
include reasonable compensation for, and reasonable expenses of, the appraisers,
but shall exclude the fees and expenses of counsel for, and experts employed by,
any party. If the fair value of the shares, as determined, materially exceeds
the amount which the corporation offered to pay therefor or if no offer was
made, the court in its discretion may award to any shareholder who is a party to
the proceeding such sum as the court determines to be reasonable compensation to
any attorney or expert employed by the shareholder in the proceeding.
 
     (10) Shares acquired by a corporation pursuant to payment of the agreed
value thereof or pursuant to payment of the judgment entered therefor, as
provided in this action, may be held and disposed of by such corporation as
authorized but unissued shares of the corporation, except that, in the case of a
merger, they may be held and disposed of as the plan of merger otherwise
provides. The shares of the surviving corporation into which the shares of such
dissenting shareholders would have been converted had they assented to the
merger shall have the status of authorized but unissued shares of the surviving
corporation.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Pursuant to section 145 of the Delaware General Corporation Law, as
amended, and the Restated Certificate of Incorporation of the Registrant,
officers, directors, employees, and agents of the Registrant are entitled to
indemnification against liabilities incurred while acting in such capacities on
behalf of the Registrant, including reimbursement of certain expenses. In
addition, the Registrant maintains an officers and directors insurance policy
pursuant to which certain officers and all directors of the Registrant are
entitled to indemnification against certain liabilities, including reimbursement
of certain expenses, and the Registrant has indemnity agreements
("Indemnification Agreements") with certain officers and all of its directors
pursuant to which such persons may be indemnified by the Registrant against
certain liabilities, including expenses.

         The Indemnification Agreements are intended to provide additional
indemnification to directors and officers of BancGroup beyond the specific
provisions of the Delaware General Corporation Law. Under the Delaware General
Corporation Law, a company may indemnify its directors and officers in
circumstances other than those under which indemnification and the advance of
expenses are expressly permitted by applicable statutory provisions.

         Under the Delaware General Corporation Law, a director, officer,
employee or agent of a corporation (i) must be indemnified by the corporation
for all expenses incurred by him (including attorneys' fees) when he is
successful on the merits or otherwise in defense of any action, suit or
proceeding brought by reason of the fact that he is or was a director, officer,
employee or agent of the corporation, (ii) may be indemnified by the corporation
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement of any such proceeding (other than a proceeding by or in the right
of the corporation) even if he is not successful on the merits if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interest of the corporation (and, in the case of a criminal proceeding, had
no reasonable cause to believe his conduct was unlawful), and (iii) may be
indemnified by the corporation for expenses (including attorneys' fees) incurred
by him in the defense or settlement of a proceeding brought by or in the right
of the corporation, if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation;
provided that no indemnification may be made under the circumstances described
in clause (iii) if the director, officer, employee or agent is adjudged liable
to the corporation, unless a court determines that, despite the adjudication of
liability but in view of all of the circumstances, he is fairly and reasonably
entitled to indemnification for the expenses which the court shall deem proper.
The indemnification described in clauses (ii) and (iii) above (unless ordered by
a court) may be made only as authorized in a specific case upon determination by
(i) a majority of a quorum of disinterested directors, (ii) independent legal
counsel in a written opinion, or (iii) the stock holders, that indemnification
is proper in the circumstances because the applicable
<PAGE>   156
standard of conduct has been met. Expenses (including attorneys' fees) incurred
by an officer or director in defending a proceeding may be advanced by the
corporation prior to the final disposition of the proceeding upon receipt of an
undertaking by or on behalf of the director or officer to repay the advance if
it is ultimately determined that he is not entitled to be indemnified by the
corporation. Expenses (including attorneys' fees) incurred by other employees
and agents may be advanced by the corporation upon terms and conditions deemed
appropriate by the board of directors.

         The indemnification provided by the Delaware General Corporation Law
has at least two limitations that are addressed by the Indemnification
Agreements: (i) BancGroup is under no obligation to advance expenses to a
director or officer, and (ii) except in the case of a proceeding in which a
director or officer is successful on the merits or otherwise, indemnification of
a director or officer is discretionary rather than mandatory.

         The Indemnification Agreements, therefore, cover any and all expenses
(including attorneys' fees and all other charges paid or payable in connection
therewith) incurred in connection with investigating, defending, being a witness
or participating in (including an appeal), or preparing to defend, be a witness
in or participate in, any threatened, pending or completed action, suit or
proceeding, or any inquiry or investigation, whether civil, criminal,
administrative or otherwise, related to the fact that such director or officer
is or was a director, officer, employee or agent of BancGroup or is or was
serving at the request of BancGroup as a director, officer, employee, agent,
partner, committee member or fiduciary of another corporation, partnership,
joint venture, employee benefit plan, trust or other enterprise, or by reason of
anything done or not done by such director or officer in any such capacity.

         The Indemnification Agreements also provide for the prompt advancement
of all expenses incurred in connection with any proceeding and obligate the
director or officer to reimburse BancGroup for all amounts so advanced if it is
subsequently determined, as provided in the Indemnification Agreements, that the
director or officer is not entitled to indemnification.

         The Indemnification Agreements further provide that the director or
officer is entitled to indemnification for, and advancement of, all expenses
(including attorneys' fees) incurred in any proceeding seeking to collect from
BancGroup an indemnity claim or advancement of expenses under the
Indemnification Agreements, BancGroup's Certificate of Incorporation, or the
Delaware General Corporation Law, regardless of whether the director or officer
is successful in such proceeding.

         The Indemnification Agreements impose upon BancGroup the burden of
proving that the director or officer is not entitled to indemnification in any
particular case, and the Indemnification Agreements negate certain presumptions
which might otherwise be drawn against a director or officer in certain
circumstances. Further, the Indemnification Agreements provide that if BancGroup
pays a director or officer pursuant to an Indemnification Agreement, BancGroup
will be subrogated to such director's or officer's rights to recover from third
parties.
<PAGE>   157
         The Indemnification Agreements stipulate that a director's or officer's
rights under such contracts are not exclusive of any other indemnity rights a
director or officer may have; however, the Indemnification Agreements prevent
double payment. The Indemnification Agreements require the maintenance of
directors' and officers' liability insurance if such insurance can be maintained
on terms, including rates, satisfactory to BancGroup.

         The benefits of the Indemnification Agreements would not be available
if (i) the action with respect to which indemnification is sought was initiated
or brought voluntarily by the officer or director (other than an action to
enforce the right to indemnification under the Indemnification Agreements); (ii)
the officer or director is paid for such expense or liability under an insurance
policy; (iii) the proceeding is for an accounting of profits pursuant to Section
16(b) of the Securities Exchange Act of 1934, as amended; (iv) the conduct of
the officer or director is adjudged as constituting an unlawful personal 
benefit, or active or deliberate dishonesty or willful fraud or illegality; or
(v) a court determines that indemnification or advancement of expenses is
unlawful under the circumstances.

         The Indemnification Agreements would provide indemnification for
liabilities arising under the Securities Act of 1933, as amended. BancGroup has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in such act and is,
therefore, unenforceable.

ITEM 22.          UNDERTAKINGS.

         (a)      The undersigned hereby undertakes as follows as required by
                  Item 512 of Regulation S-K:

                  (1)      That prior to any public reoffering of the securities
                           registered hereunder through use of a prospectus
                           which is a part of this Registration Statement, by
                           any person or party who is deemed to be an
                           underwriter within the meaning of Rule 145(c), the
                           issuer undertakes that such reoffering prospectus
                           will contain the information called for by the
                           applicable registration form with respect to
                           reofferings by persons who may be deemed
                           underwriters, in addition to the information called
                           for by the other Items of the applicable form.

                  (2)      That every prospectus (i) that is filed pursuant to
                           paragraph (1) immediately above, or (ii) that
                           purports to meet the requirements of section 10(a)(3)
                           of the Act and is used in connection with an offering
                           of securities subject to Rule 415, will be filed as a
                           part of an amendment to the Registration Statement
                           and will not be used until


                                        6
<PAGE>   160
                           such amendment is effective, and that, for purposes
                           of determining any liability under the Securities Act
                           of 1933, each such post-effective amendment shall be
                           deemed to be a new Registration Statement relating to
                           such securities offered therein, and the offering of
                           such securities at that time shall be deemed to be
                           the initial bona fide offering thereof.

                  (3)      Insofar as indemnification for liabilities arising
                           under the Act may be permitted to directors,
                           officers, and controlling persons of the Registrant,
                           the Registrant has been advised that in the opinion
                           of the Securities and Exchange Commission such
                           indemnification is against public policy as expressed
                           in the Act and is, therefore, unenforceable. In the
                           event that a claim for indemnification against such
                           liabilities (other than the payment by the Registrant
                           of expenses incurred or paid by a director, officer
                           or controlling person of the Registrant in the
                           successful defense of any action, suit or proceeding)
                           is asserted by such director, officer or controlling
                           person in connection with the securities being
                           registered, the Registrant will, unless in the
                           opinion of its counsel the matter has been settled by
                           controlling precedent, submit to a court of
                           appropriate jurisdiction the question whether such
                           indemnification by it is against public policy as
                           expressed in the Act and will be governed by the

                                    which, individually or in the aggregate,

                           therein, and the offering of such securities at that

                  incorporated by reference in the Registration Statement shall
                  be deemed to be a new Registration Statement relating to the
                  securities offered therein, and the offering of such

         3.       ADMINISTRATION OF THE PLAN.

         (a)      PROCEDURAL RULES.

                  (i)      The Plan shall be administered by a Committee
                           appointed by the Board.

                  (ii)     The Board shall appoint a Committee, consisting of
                           not less than three members of the Board who are not
                           also employees, to administer the Plan on behalf of
                           the Board, subject to such terms and conditions as
                           the Board may prescribe. Once appointed, the
                           Committee shall continue to serve until otherwise
                           directed by the Board. From time to time the Board
                           may increase the size of the Committee and appoint
                           additional members thereof, remove members (with or
                           without cause) and appoint new members in
                           substitution therefor, and fill vacancies, however
                           caused. A majority of the entire Committee shall
                           constitute a quorum and the action of the majority of
                           the members present at any meeting at which a quorum
                           is present shall be deemed the action of the
                           Committee, not counting the vote of a member whose
                           option is the subject of the action. In addition, any
                           decision or determination reduced to writing and
                           signed by all of the members of the Committee shall
                           be as fully effective as if it had been made by a
                           majority vote at a meeting duly called and held. The
                           Committee may appoint a secretary to keep minutes of
                           its meetings and may make such rules and regulations
                           for the conduct of its business as it shall deem
                           advisable.

                  (iii)    The members of the Committee shall be eligible to
                           receive Options.

         (b)      POWERS OF THE COMMITTEE. Subject to the provisions of the
                  Plan, the Committee shall have the authority:

                  (i)      To recommend to the Board for approval the directors
                           to whom and the time or times at which Options shall
                           be granted and the number of Shares to be represented
                           by each Option.

                  (ii)     To interpret the Plan and option agreements entered
                           into hereunder;

                  (iii)    To prescribe, amend and rescind rules and regulations
                           relating to the Plan and any option agreements
                           entered into hereunder;

                  (iv)     To authorize any person to execute on behalf of the
                           Company any instrument required to effectuate the
                           grant of an Option previously granted by the
                           Committee; and


                                       18
<PAGE>   4
                  (v)      To make all other determinations deemed necessary or
                           advisable for the administration of the Plan.

         (c)      EFFECT OF COMMITTEE'S DECISION. The implementation,
                  interpretation and construction by the Committee of any
                  provisions of the Plan or of any Option granted hereunder
                  shall be final and conclusive, unless otherwise determined by
                  the Board. No member of the Board or the Committee shall be
                  liable for any action or determination made in good faith with
                  respect to the Plan or any Option granted under it.

         4.       ELIGIBILITY. Options may be granted under this Plan by the 
Board to directors of the Company and/or its subsidiaries. The Board shall
determine the terms and provisions of each Option granted under the Plan (which
need not be identical) and, with the consent of the holder thereof, prescribe
modifications or amendments to any Option. The vote of a director shall not be
counted in the Board's determining the granting of an option, or the terms and
conditions of the option, to such director.

         5.       TERM OF PLAN. The Plan shall become effective upon its 
adoption by the Board, subject to the condition that it be approved by the vote
of the holders of a majority of the outstanding common stock of the Company
within twelve months thereafter. The Plan shall continue in effect for a term
of 10 years from the date of its adoption by the Board unless sooner
terminated under the provisions of Section 8 of the Plan.

         6.       TERMS AND CONDITIONS OF OPTIONS. All Options granted pursuant
to this Plan must be granted within ten (10) years from the date the Plan is
adopted by the Board. Each Option shall be evidenced by a written stock option
agreement in such form as the Committee shall, from time to time, approve and
shall comply with and be subject to the following terms and conditions:

         (a)      OPTION PRICE. Each option agreement shall state the number of
                  Shares to which it pertains and the option price, which shall
                  be the book value at the close of business of the month end
                  preceding the date upon which the Option is granted. For the
                  purpose of this Plan, the term "book value" shall be the sum
                  of the capital stock, surplus and retained earnings accounts
                  of the Company.

         (b)      OPTION. Each Option shall state the date on which it is
                  granted. Each Option shall be exercisable at such time(s) and
                  under such condition(s) as shall be permissible under the
                  terms of this Plan and of the Option granted to the Optionee,
                  but in no event shall an Option be exercisable after the
                  expiration of ten (10) years from the date of grant. Except as
                  otherwise hereinafter provided in case of disability or death,
                  an Option can only be exercised during, or within ninety (90)
                  days after the termination of, an Optionee's directorship with
                  the Company, or any parent or subsidiary of the


                                       19
<PAGE>   5
                  Company which now exists or hereafter is organized or acquired
                  by or acquires the Company; provided however, that no Option,
                  or any part of an Option, shall be exercisable before the date
                  it would otherwise be exercisable.

                  If the Optionee's directorship with the Company or a parent or
                  subsidiary of the Company is terminated by reason of permanent
                  and total disability, the exercise period shall be extended
                  for a period of six (6) months following the date of
                  termination of the Optionee's directorship subject to the
                  condition that no Option shall be exercisable after the
                  expiration of ten (10) years from the date it is granted or
                  before the date it would otherwise be exercisable. Permanent
                  and total disability shall exist if the Optionee is unable to
                  engage in any substantial gainful activity by reason of any
                  medically determinable physical or mental impairment which can
                  be expected to result in death or which has lasted and can be
                  expected to last for a continuous period of not less than 12
                  months.

                  If the Optionee dies while a director of the Company or a
                  parent or subsidiary of the Company and shall not have fully
                  exercised Options granted pursuant to the Plan, such Options
                  may be exercised in whole or in part at any time within one
                  (1) year after the Optionee's death by the executor or
                  administrator of the Optionee's estate or by any person or
                  persons who shall have acquired the Options directly from the
                  Optionee by bequest or inheritance, subject to the condition
                  that no Option shall be exercisable after the expiration of
                  ten (10) years from the date it is granted or before the date
                  it would otherwise be exercisable.

         (c)      TRANSFERABILITY LIMITATIONS. Any Option granted hereunder may
                  not be sold, pledged, assigned, hypothecated, transferred, or
                  disposed of in any manner other than by Will or by the laws of
                  descent and distribution and shall be exercisable, during the
                  Optionee's lifetime, only by him or her.

         (d)      PROCEDURE FOR EXERCISE.

                  (i)      An Option shall be deemed to be exercised when
                           written notice of such exercise has been given to the
                           Company in accordance with the terms of the Option by
                           the person entitled to exercise the Option and full
                           payment for the Shares with respect to which the
                           Option is exercised has been received by the Company.
                           The Option price shall be paid in cash or by the
                           surrender, at fair market value on the date on which
                           the Option is exercised of Shares, or by any
                           combination of cash and Shares. Until the issuance or
                           transfer of the stock certificate(s) (as evidenced by
                           the appropriate entry on the books of the Company or
                           of a duly authorized transfer agent of the Company),
                           no right to vote or to receive dividends or any other
                           rights as a

<PAGE>   6
                           stockholder shall exist with respect to Optioned
                           Stock notwithstanding the exercise of the Option. No
                           adjustment will be made for a dividend or other
                           rights for which the record date is prior to the date
                           the stock certificates are issued or transferred
                           except as provided in Section 7 of the Plan.

                  (ii)     An Option may not be exercised for fractional Shares.

         (e)      ADDITIONAL PROVISIONS. The option agreements authorized under
                  the Plan shall contain such other provisions as the Committee
                  shall deem advisable, including, without limitation,
                  restrictions upon the exercise of the Option.

         (f)      CONDITIONS UPON ISSUANCE OF SHARES.

                  (i)      LEGAL RESTRICTIONS. Shares shall not be issued or
                           sold with respect to an Option granted under the Plan
                           unless the grant and exercise of such Option and the
                           issuance or sale and delivery of such Shares pursuant
                           thereto shall comply with all applicable provisions
                           of law including, without limitation, the Securities
                           Act of 1933, as amended, the Securities Exchange Act
                           of 1934, as amended, the Florida Securities Act, the
                           rules and regulations promulgated thereunder and
                           shall be further subject to the approval of counsel
                           for the Company with respect to such compliance.

                  (ii)     REPRESENTATIONS REQUIRED. As a condition to the
                           exercise of an Option, the Company may require the
                           Participant to represent and warrant at the time of
                           any such exercise that the Shares are being purchased
                           by the Optionee for the Optionee's own account for
                           investment and without an intention to sell or
                           distribute such Shares if, in the opinion of counsel
                           for the Company, such a representation is required by
                           applicable law.

         7.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. In the event that
the outstanding shares of the Common Stock of the Company shall be increased,
decreased, or otherwise changed in number, class, or character by reason of any
issuance or repurchase of Common Stock, or subdivision or combination of the
outstanding Common Stock of the Company into a greater or lesser number of
shares, split-up, change of par value, common stock dividend, reclassification
of shares, recapitalization, merger, consolidation, exchange of shares, or sale,
lease, or conveyance of substantially all the assets of the Company, or other
change in the capitalization or organization of the Company, or shall be changed
in value by reason of any so-called spin-off dividend in partial liquidation or
other special distribution, the Committee shall, in light of such change, make
such adjustments, if any, as it deems to be equitable in (1) the respective
numbers of Shares and/or the respective option price specified in the Options
theretofore granted under this Plan and then


                                       21
<PAGE>   7
outstanding, and (2) the aggregate number of Shares of Common Stock which may be
purchased upon the exercise of Options granted under this Plan, as set forth in
Section 2 thereof. Such adjustment shall not result in the issuance of
fractional Shares. In the event of the issuance of any warrants, rights to
purchase, or other securities of the Company to all holders of Common Stock,
then Optionee shall also receive such warrants, rights to purchase, or other
securities attributable to each share of Common Stock reserved for issuance or
sale to Optionee hereunder upon issuance or sale to Optionee hereunder upon
issuance or sale of shares of Common Stock to Optionee after exercise of the
Option.

         The foregoing adjustments shall be made by the Committee, subject to
the approval of the Board. The grant of an Option pursuant to the Plan shall not
affect in any way the right or power of the Company to make adjustments,
reclassifications, reorganizations, or changes in its capital or business
structure or to merge or consolidate or dissolve, liquidate, or sell, or
transfer all or any part of its business or assets.

         8.       AMENDMENT AND TERMINATION OF THE PLAN.

         (a)      AMENDMENT. The Board may amend the Plan from time to time in
                  such respects as the Board may deem advisable.

         (b)      EFFECT OF AMENDMENT OR TERMINATION. The amendment or
                  termination of this Plan shall not, without the consent of an
                  affected Optionee, alter or impair any rights or obligations
                  previously granted hereunder.

         9.       RESERVATION OF SHARES. The Company, during the term of this
Plan, will at all times reserve and keep available the number of Shares as shall
be sufficient to satisfy the requirements of the Plan.

         10.      LIABILITY OF COMPANY. The Company, its parent, or any 
subsidiary which is in existence or hereafter comes into existence, shall not be
liable to the Optionee or other person as to:

         (a)      NONISSUANCE OR SALE OR SHARES. The nonissuance or sale of
                  Shares as to which the Company has been unable to obtain from
                  any regulatory body having jurisdiction the authority deemed
                  by the Company's counsel to be necessary to the lawful
                  issuance and/or sale of any Shares hereunder; or

         (b)      TAX CONSEQUENCES. Any tax or securities consequences expected,
                  but not realized, by the Optionee or other person due to the
                  grant or exercise of any Option granted hereunder.

         (a)      OPTION PRICE. Each option agreement shall state the number of
                  Shares to which it pertains and the option price, which shall
                  be the book value at the close of business of the month end
                  preceding the date upon which the Option is granted. For the
                  purpose of this Plan the terms "book value" shall be the sum
                  of the capital stock, surplus and retained earnings accounts
                  of the Company.

         (b)      OPTION. Each Option shall state the date on which it is
                  granted. Each Option shall be exercisable at such time(s) and
                  under such condition(s) as shall be permissible under the
                  terms of this Plan and of the Option granted to the Optionee,
                  but in no event shall an Option be exercisable after the
                  expiration of ten (10) years from the date of grant. Except as
                  otherwise hereinafter provided in case of disability or death,
                  an Option can only be exercised during, or within ninety (90)
                  days after the termination of, an Optionee's employment with
                  the Company, or any parent or subsidiary of the Company which
                  now exists or hereafter is organized or acquired by or
                  acquires the Company; provided however, that no Option, or any
                  part of an Option, shall be exercisable before the date it
                  would otherwise be exercisable.

<PAGE>   5
                  If the Optionee's employment with the Company or a parent or
                  subsidiary of the Company is terminated by reason of permanent
                  and total disability, the exercise period shall be extended
                  for a period of six (6) months following the date of
                  termination of the Optionee's employment subject to the
                  condition that no Option shall be exercised after the
                  expiration of ten (10) years from the date it is granted or
                  before the date it would otherwise be exercisable. Permanent
                  and total disability shall exist if the Optionee is unable to
                  engage in any substantial gainful activity by reason of any
                  medically determinable physical or mental impairment which can
                  be expected to result in death or which has lasted and can be
                  expected to last for a continuous period of not less than 12
                  months.

                  If the Optionee dies while in the employ of the Company or a
                  parent or subsidiary of the Company and shall not have fully
                  exercised Options granted pursuant to the Plan, such Options
                  may be exercised in whole or in part at any time within one
                  (1) year after the Optionee's death by the executor or
                  administrator of the Optionee's estate or by any person or
                  persons who shall have acquired the Options directly from the
                  Optionee by bequest or inheritance, subject to the condition
                  that no Option shall be exercisable after the expiration of
                  ten (10) years from the date it is granted or before the date
                  it would otherwise be exercisable.

         (c)      TRANSFERABILITY LIMITATIONS. Any Option granted hereunder may
                  not be sold, pledged, assigned, hypothecated, transferred, or
                  disposed of in any manner other than by Will or by the laws of
                  descent and distribution and shall be exercisable, during the
                  Optionee's lifetime, only by him or her.

         (d)      PROCEDURE FOR EXERCISE.

                  (i)      An Option shall be deemed to be exercised when
                           written notice of such exercise has been given to the
                           Company in accordance with the terms of the Option by
                           the person entitled to exercise the Option and full
                           payment for the Shares with respect to which the
                           Option is exercised has been received by the Company.
                           The Option price shall be paid in cash or by the
                           surrender, at fair market value on the date on which
                           the Option is exercised of Shares, or by any
                           combination of cash and Shares. Until the issuance or
                           transfer of the stock certificate(s) (as evidenced by
                           the appropriate entry on the books of the Company or
                           of a duly authorized transfer agent of the Company),
                           no right to vote or receive dividends or any other
                           rights as a stockholder shall exist with respect to
                           Optioned Stock notwithstanding the exercise of the
                           Option. No adjustment will be made for a dividend or
                           other rights for which the record date is prior to
                           the date of the stock certificates are issued or
                           transferred except as provided in

                           sold with respect to an Option granted under the Plan
                           unless the grant and exercise of such Option and the
                           issuance or sale and delivery of such Shares pursuant
                           thereto shall comply with all applicable provisions
                           of law including, without limitation, the Securities
                           Act of 1933, as amended, the Securities Exchange Act
                           of 1934, as amended, the Florida Securities Act, the
                           rules and regulations promulgated thereunder and
                           shall be further subject to the approval of counsel
                           for the Company with respect to such compliance.

                  (ii)     REPRESENTATIONS REQUIRED. As a condition to the
                           exercise of an Option, the Company may require the

                           investment and without an intention to sell or
                           distribute such Shares if, in the opinion of counsel
                           for the Company, such a representation is required by
                           applicable law.

         7.       ADJUSTMENT UPON CHANGES IN CAPITALIZATION. In the event that

other special distribution, the Committee shall, in light of such change, make
such adjustments, if any, as it deems to be equitable in (1) the respective
numbers of Shares and/or the respective option price specified in the Options
theretofore granted under this Plan and then outstanding, and (2) the aggregate
number of Shares of Common Stock which may be purchased upon the exercise of
Options granted under this Plan, as set forth in Section 2 thereof. Such
adjustment shall not result in the issuance of fractional Shares. In the event
of the issuance of any warrants, rights to purchase, or other securities of the
Company to all holders of Common Stock, then Optionee shall also receive such
warrants, rights to purchase, or other securities attributable to each share of
Common Stock reserved for issuance or sale to Optionee hereunder upon issuance
or sale to Optionee hereunder upon issuance or sale of Common Stock to Optionee
after exercise of the Option.

         The foregoing adjustments shall be made by the Committee, subject to
the approval of the Board. The grant of an Option pursuant to the Plan shall not
affect in any way the right or power of the Company to make adjustments,

                  termination of this Plan shall not, without the consent of an
                  affected Optionee, alter or impair any rights or obligations
                  previously granted hereunder.

"Agreement"), by and between the Company and First Commerce Banks of Florida,
Inc. and the issuance by the Company of its Common Stock pursuant to stock

the caption above. In this connection we have reviewed such documents and
matters of law as we have deemed relevant and necessary as a basis for the

         Upon the basis of the foregoing, we are of the opinion that:

         (i) The Company is a corporation duly organized and existing under the
laws of

the State of Delaware;

         (ii) The shares of Common Stock of the Company referred to above, to
the extent actually issued pursuant to the Agreement will, when so issued, be
duly and validly authorized and issued and will be fully paid and nonassessable

attaches to the ownership of the shares of Common Stock of the Company.

         We hereby consent to the filing of this opinion as an exhibit to the

opinion in the Registration Statement, we do not thereby admit that we are a

Mr. Flake Oakley
Chief Financial Officer
Colonial BancGroup, Inc.
P.O. Box 1109
Montgomery, AL 36101

Dear Mr. Oakley:

For various business reasons, First Commerce Banks of Florida, Inc. (Acquired
Corporation) and The Colonial BancGroup, Inc. (BancGroup) have entered into an
Agreement and Plan of Merger (Agreement). Pursuant to your request, our letter
addresses the income tax consequences of the proposed transaction as outlined
below. We will address whether the merger will qualify as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986
(I.R.C.). We will also address additional income tax consequences to Acquired
Corporation, BancGroup, and shareholders.

BACKGROUND

Acquired Corporation, a Florida corporation, operates as a bank holding company
for its wholly owned subsidiary, First Commerce Bank of Polk County (Bank), with
its principal office in Winter Haven, Florida. BancGroup, a Delaware
corporation, is a bank holding company with Subsidiary banks in Florida
(Colonial Bank), Alabama, Georgia and Tennessee.

CERTAIN TERMS OF THE MERGER

At the effective date of the merger, Acquired Corporation will merge with and
into BancGroup, with BancGroup as the surviving corporation. Pursuant to the
terms of the transaction, each share of common stock of Acquired Corporation
outstanding and held by Acquired Corporation's shareholders other than shares
held by shareholders who perfect their dissenter's rights, will be converted by
operation of law and without any action on the part of the parties or the
holders thereof into shares of BancGroup Common Stock at a rate of .4326 of a
share of BancGroup Common Stock for each share of Acquired Corporation Stock. On
the effective date and as a result of the merger, BancGroup will assume all the
outstanding options of Acquired Corporation, whether or not vested or
exercisable. Each such option will cease to represent a right to acquire
Acquired Corporation Common Stock and will, instead, represent a right to
acquire BancGroup common stock on substantially


                                       41
<PAGE>   3
the same terms applicable to the Acquired Corporation Options except as
specified in the Agreement.

No fractional shares of BancGroup Common Stock will be issued. Instead, each
holder of shares of Acquired Corporation Stock having a fractional interest
arising upon the conversion of such shares into shares of BancGroup Common Stock
shall, at the time of surrender of the certificates previously representing
Acquired Corporation Stock, be paid by BancGroup an amount in cash. Any
shareholder of Acquired Corporation who does not vote in favor of the Agreement
and who complies with certain procedures relating to the rights of dissenting
shareholders will be entitled to receive payment for the fair value of his or
her Acquired Corporation Stock.

Further, after consummation of the merger, BancGroup and Acquired Corporation
anticipate merging two bank subsidiaries, the Bank and Colonial Bank. Colonial
Bank will be the surviving entity.

REPRESENTATIONS OF PARTIES

         -        BancGroup and Acquired Corporation intend that the merger will
                  qualify for federal income tax purposes as a "reorganization"
                  within the meaning of I.R.C. Section 368(a) of the Code.

         -        The fair market value of the BancGroup stock received by each
                  shareholder of Acquired Corporation pursuant to the terms of
                  the Agreement will be approximately equal to the fair market
                  value of Acquired Corporation surrendered in the exchange. The
                  terms of the Agreement are the result of arm's-length
                  negotiations between unrelated parties.

         -        There is no plan or intention by the shareholders of Acquired
                  Corporation to sell, exchange, or otherwise dispose of a
                  number of shares of acquiring stock received in the
                  transaction that will reduce the Acquired Corporation
                  shareholders' ownership of BancGroup stock to a number of
                  shares having a value, as of the date of the transaction, of
                  less than fifty percent of the value of all of the formerly
                  outstanding stock of Acquired Corporation as of the same date.
                  For purposes of this representation, shares of Acquired stock
                  exchanged for cash, and surrendered by dissenters, or
                  exchanged for cash in lieu of fractional shares of BancGroup
                  stock will be treated as outstanding Acquired Corporation
                  stock on the date of the transaction. Shares of Acquired stock
                  and shares of BancGroup stock held by Acquired Corporation
                  shareholders and otherwise sold, redeemed or disposed of prior
                  or subsequent to the transaction will be considered in making
                  this representation.

         -        Following the merger, BancGroup will continue the historic
                  business of Acquired Corporation or use a significant portion
                  of Acquired Corporation's historic business assets in a
                  business.


                                       42
<PAGE>   4
         -        Acquired Corporation, BancGroup and Acquired Shareholders will
                  pay their respective expenses, if any, incurred in connection
                  with the transaction.

         -        No part of the consideration received by the Acquired
                  Corporation shareholders will be received by them in their
                  capacity as debtor, creditor, employee, or any way other than
                  as shareholder.

         -        The fair market value of the assets of Acquired Corporation
                  transferred to BancGroup will equal or exceed the sum of the
                  liabilities assumed by BancGroup plus the amount of
                  liabilities, if any, to which the assets transferred are
                  subject.

         -        The total adjusted basis of the assets of Acquired Corporation
                  transferred to BancGroup will equal or exceed the sum of the
                  liabilities assumed by BancGroup plus the amount of
                  liabilities, if any, to which the assets transferred are
                  subject.

         -        If nonqualified stock options to purchase Acquired Corporation
                  common stock are exchanged for nonqualified stock options to
                  purchase BancGroup common stock, then the difference between
                  the option price and fair market value of BancGroup common
                  stock subject to options immediately after the exchange will
                  be equal to (or greater than) the difference between the
                  option price and the fair market value of Acquired Corporation
                  common stock subject to options immediately before the
                  exchange. All other terms of the BancGroup nonqualified stock
                  options will be the same as those of Acquired Corporation's
                  nonqualified stock options.

         -        Any incentive stock options acquired from Acquired Corporation
                  as a part of the merger and reissued by BancGroup will be
                  issued at substantially the same terms, so as not to create
                  material modification as defined in I.R.C. Section 424.

TAX CONSEQUENCES TO ACQUIRED CORPORATION AND BANCGROUP

The merger of Acquired Corporation with and into BancGroup will constitute a
merger within the meaning of I.R.C. Section 368(a)(1)(A), provided that the
merger qualifies as a statutory merger pursuant to state law. Acquired
Corporation and BancGroup will each be "a party to the reorganization" within
the meaning of I.R.C. Section 368(b) of the Code. Based upon I.R.C. Sections
357(a) and 361(a), Acquired Corporation will recognize no gain or loss when it
transfers its assets to BancGroup in a constructive exchange solely for
BancGroup's stock and the assumption of Acquired Corporation's liabilities by
BancGroup. Acquired Corporation will not recognize any gain or loss upon the
receipt of cash in the exchange if it distributes such property as part of the
plan of reorganization under I.R.C. Section 361(b).

Pursuant to I.R.C. Section 1032 of the Code, no gain or loss will be recognized
by BancGroup upon the acquisition by BancGroup of the assets of Acquired
Corporation in exchange for BancGroup common stock and the assumption of
Acquired Corporation's


                                       43
<PAGE>   5
liabilities. BancGroup's basis in the assets acquired in the transaction will be
equal to the basis of the assets in the hands of Acquired Corporation
immediately before the transaction under I.R.C. Section 362(b). I.R.C. Section
1223(2) provides that BancGroup's holding period for each Acquired Corporation
asset received in the merger will include the period during which the asset was
held by Acquired Corporation immediately before the transaction.

Pursuant to I.R.C. Section 381(a), BancGroup will succeed to and take into
account the items of Acquired Corporation described in I.R.C. Section 381(c),
subject to the conditions and limitations of I.R.C. Sections 381, 382, 383, 384,
and 1502 and the regulations thereunder. BancGroup will succeed to and take into
account the earnings and profits, or deficit in earnings and profits, of
Acquired Corporation as provided by I.R.C. Section 382(c)(2) of the Code and
Section 1.381(c)(2)-1 of the Regulations.

TAX CONSEQUENCES TO BANK AND COLONIAL BANK

The merger of Bank with and into Colonial Bank will constitute a merger within
the meaning of I.R.C. Section 368(a)(1)(A), provided that the merger qualifies
as a statutory merger pursuant to state law. Bank and Colonial Bank will each be
"a party to the reorganization" within the meaning of I.R.C. Section 368(b) of
the Code. Based upon I.R.C. Sections 357(a) and 361(a), Bank will recognize no
gain or loss when it transfers its assets to Colonial Bank's in a constructive
exchange solely for Colonial Bank's stock and the assumption of Colonial Bank's
liabilities by BancGroup. Bank will also not recognize any gain or loss upon the
receipt of cash in the exchange if it distributes such property as part of the
plan of reorganization under I.R.C. Section 361(b).

Pursuant to I.R.C. Section 1032 of the Code, no gain or loss will be recognized
by Colonial Bank upon the acquisition by Colonial Bank of the assets of Bank in
exchange for Colonial Bank's common stock and the assumption of Bank's
liabilities. Colonial Bank's basis in the assets acquired in the transaction
will be equal to the basis of the assets in the hands of Bank immediately before
the transaction per I.R.C. Section 362(b). I.R.C. Section 1223(2) provides that
Colonial Bank's holding period for each Bank asset received in the merger will
include the period during which the asset was held by Bank immediately before
the transaction.

Pursuant to I.R.C. Section 381(a), Colonial Bank will succeed to and take into
account the items of Bank described in I.R.C. Section 381(c), subject to the
conditions and limitations of I.R.C. Sections 381, 382, 383, 384, and 1502 and
the regulations thereunder. Colonial Bank will succeed to and take into account
the earnings and profits, or deficit in earnings and profits, of Bank as
provided by I.R.C. Section 382(c)(2) of the Code and Section 1.381(c)(2)-1 of
the Regulations.

TAX CONSEQUENCES TO ACQUIRED CORPORATION SHAREHOLDERS


                                       44
<PAGE>   6
I.R.C. Section 354 states that a shareholder who receives solely BancGroup
common stock in exchange for Acquired Corporation common stock will recognize no
gain or loss on the exchange, except with respect to cash received in lieu of a
fractional interest in BancGroup common stock. I.R.C. Section 358 of the Code
provides that the shareholder's tax basis in the BancGroup common stock received
in the exchange will be the same as the basis of the Acquired Corporation common
stock surrendered, decreased by the amount of cash (if any) received by the
shareholder and increased by the amount of gain (if any) recognized in the
exchange. I.R.C. Section 1223 of the Code provides that such shareholder will
include the period during which Acquired Corporation stock was held in his
holding period for the BancGroup common stock received in the exchange.

The payment of cash in lieu of fractional shares of BancGroup common stock will
be treated as if the fractional shares were issued as part of the exchange and
then redeemed by BancGroup. These cash payments will be treated as having been
received as distributions in full payment in exchange for the stock redeemed as
provided in I.R.C. Section 302(a) of the Code. Generally, any gain or loss
recognized upon such exchange will be capital gain or loss, provided the
fractional share constitutes a capital asset in the hands of the exchanging
shareholder. The shareholders will recognize capital gain or loss equal to the
difference between the cash received and the basis of the fractional share
interest that would have been issued.

Holders of shares of Acquired Corporation Common Stock who receive cash upon the
exercise of any appraisal rights will be subject to a taxable transaction for
federal income tax purposes. Such a shareholder will recognize gain or loss
measured by the difference between the tax basis for his or her shares and the
amount of cash received pursuant to I.R.C. Section 1012 of the Code (unless the
receipt of cash is treated as a dividend, as described below).

In certain circumstances, the receipt of solely cash by an Acquired Corporation
shareholder could be treated as a dividend (to the extent of the shareholder's
ratable share of applicable earnings and profits) if the shareholder
constructively owns shares of Acquired Corporation Common Stock that are
exchanged for BancGroup Common Stock in the Merger. Generally, a shareholder
constructively owns stock that is owned by members of the shareholder's family,
and by certain controlled or related partnerships, estates, trusts and
corporations, pursuant to the constructive ownership rules of I.R.C. Section 318
of the Code, as well as any shares that the shareholder has an option to
acquire.

The receipt of solely cash by an Acquired Corporation shareholder in exchange
for his stock will not be treated as a dividend if such exchange or receipt
results in a meaningful reduction or a substantially disproportionate reduction
in the shareholder's ownership interest or results in a complete termination of
the shareholder's interest, taking into account, in each case, the constructive
ownership rules described above. A complete termination of a shareholder's
interest will occur if, after the receipt of cash in exchange for stock, the
shareholder owns no shares of stock in BancGroup. Thus, a shareholder who


                                       45
<PAGE>   7
receives solely cash for all of the stock actually owned by him will generally
qualify for capital gain treatment under the complete termination test if none
of the shares constructively owned by him are exchanged in the merger for
BancGroup Common Stock and the shareholder does not otherwise own, actually or
constructively, any shares of BancGroup Common Stock after the merger.

Where the complete termination of interest test is not satisfied with respect to
a particular shareholder (because, for example, Acquired Corporation shares
owned by a related party are exchanged for BancGroup Common Stock in the
merger), that shareholder will nonetheless generally be entitled to capital gain
treatment if the receipt of cash in exchange for his shares results in a
"substantially disproportionate" reduction or a "meaningful" reduction in his
ownership interest. I.R.C. Section 302 of the Code provides that a shareholder's
reduction in ownership interest should normally be "substantially
disproportionate," and capital gain treatment should normally result, if (1) the
shareholder owns less than 50% of the total combined voting power of all classes
of stock immediately after the merger, and (2) the shareholder's proportionate
stock interest in BancGroup immediately after the merger is 20% or more below
what his proportionate interest in BancGroup would have been if he had received
solely BancGroup Common Stock in the merger.

Acquired Corporation shareholders who constructively own stock in Acquired
Corporation should consult a tax advisor regarding the characterization of cash
payments received in the reorganization in exchange for Acquired Corporation
stock as either capital gain income or dividend income.


CONVERSION OF ACQUIRED CORPORATION OPTIONS INTO BANCGROUP OPTIONS

         INCENTIVE STOCK OPTIONS

The assumption and conversion of Acquired Corporation incentive stock options,
whether vested or exercisable, into rights to acquire BancGroup common stock
pursuant to the terms of the Agreement shall not be considered the granting of a
new option as long as the following requirements of I.R.C. Section 424 are met.
I.R.C. Section 424 provides that the excess of the aggregate fair market value
of the shares subject to the options immediately after the substitution or
assumption over the aggregate option price of such shares is not more than the
excess of the aggregate fair market value of all shares subject to the option
immediately before such substitution or assumption over the aggregate option
price of such shares. Section 424 also provides that the new option or the
assumption of the old option must not give the employee additional benefits
which he did not have under the old option. If the terms of the old option are
modified, extended, or renewed, such modification, extension, or renewal shall
be considered the granting of a new option which will disqualify the option as
an incentive stock option.


                                       46
<PAGE>   8
The shareholders of Acquired Corporation, in lieu of receiving BancGroup
options, can elect to receive shares of BancGroup common stock for the
difference between the exercise price of Acquired Corporation options and the
fair market value of BancGroup stock at the effective date of the Agreement.
This election, if made, is effectively a "cashless exercise" of an incentive
stock option (i.e. the option holder is treated as exercising all of the options
and remitting a portion of the Bancgroup stock to Acquired Corporation in
satisfaction of the exercise price ("foregone stock"). The cashless exercise of
Acquired Corporation incentive stock options will result in the option holder
recognizing ordinary income equal to the amount of the bargain purchase element
of the Bancgroup stock foregone. In addition, if Acquired Corporation's
incentive stock plan does not have a cashless exercise feature, the cashless
exercise of an incentive stock option by an option holder could be interpreted
as a material modification under I.R.C. Section 424. If the cashless exercise
feature constituted a material modification, all incentive stock options of
Acquired Corporation would lose their status as incentive stock options and
would be taxed as nonqualified stock options. The disqualification of an
incentive stock option would entitle Acquired Corporation to a compensation
deduction when the option is exercised.

         NONQUALIFIED STOCK OPTIONS

The assumption and conversion of Acquired Corporation nonqualified stock options
into BancGroup nonqualified stock options pursuant to the merger will not result
in current federal income tax consequences if neither the nonqualified options
to purchase shares of Acquired Corporation stock nor the substituted options to
purchase BancGroup stock have a readily ascertainable value. I.R.C. Section
83(e) provides that I.R.C. Section 83 does not apply to the transfer of an
option without a readily ascertainable fair market value. The regulations under
Section 1.83-7 state that if an option is not actively traded on an established
market, the option does not have a readily ascertainable fair market value when
granted unless a taxpayer can show that the option is transferable by the
optionees; the option is exercisable immediately in full by the optionee; the
option or property subject to the option is not subject to any restriction or
condition that has a significant effect upon the fair market value of the
option; and, the fair market value of the option privilege is readily
ascertainable under the provision for determining fair market value in the case
of options not actively traded on an established market.

The shareholders of Acquired Corporation, in lieu of receiving BancGroup
options, can elect to receive shares of BancGroup common stock for the
difference between the exercise price of Acquired Corporation options and the
fair market value of BancGroup stock at the effective date of the Agreement. The
cashless exercise of nonqualified stock options does not alter the timing or
character of income recognition. The shareholders of Acquired Corporation will
recognize ordinary income for the fair market value of the stock received in
conjunction with the exercise of the options (i.e. the difference between the
fair market value of Bancgroup stock and the exercise price). Acquired
Corporation is entitled to a corresponding compensation deduction of the same
amount.

SUMMARY

The merger of BancGroup and Acquired Corporation will qualify as a tax-free
reorganization within the meaning of I.R.C. Section 368(a)(1)(A). BancGroup's
basis in Acquired Corporation's assets will be the same as Acquired
Corporation's basis in its assets before the merger. The merger of Colonial Bank
and Bank will also qualify as a tax-free reorganization within the meaning of
I.R.C. Section 368(a)(1)(A). Colonial Bank's basis in Bank's assets will be the
same as Bank's basis in its assets before the merger. Acquired Corporation
shareholders will retain a substituted basis in the shares of BancGroup stock
received in the merger decreased by the amount of cash received and increased by
the amount of gain recognized in the deal. The only taxable consequences will be
to those shareholders who receive cash in lieu of fractional shares and those
shareholders who receive solely cash in the exchange upon perfecting their
dissenter's rights. Shareholders receiving cash must examine their actual and
constructive ownership of Acquired Corporation and BancGroup stock for purposes
of determining the tax consequences of the cash payments.

The cashless exercise of Acquired Corporation incentive stock options will
result in the option holders recognizing ordinary income equal to the amount of
the bargain purchase element of the BancGroup stock foregone. In addition, there
is a risk that a cashless exercise of incentive stock options could be treated
as a material modification under I.R.C. Section 424, subjecting all incentive
stock options issued by Acquired Corporation to taxation as nonqualified stock
options. The cashless exercise of Acquired Corporation nonqualified stock
options will result in the option holders recognizing ordinary income equal to
the fair market value of stock received, with a corresponding compensation
deduction to Acquired Corporation.
