                                    SUMMARY
 
     The following provides a summary of information included in this
Prospectus. The summary is qualified in its entirety by the more detailed
information appearing elsewhere herein, the Appendices hereto and the documents
incorporated herein by reference. Stockholders of the Bank are urged to read
this document in full.
 
GENERAL
 
     This Prospectus relates to the issuance of shares of BancGroup Common Stock
and the offer of cash pursuant to the Merger of the Bank with and into Colonial
Bank. Colonial Bank will be the surviving corporation in the Merger. See
"APPROVAL OF THE MERGER."
 
     The Merger will be presented for approval at the Special Meeting of the
stockholders of the Bank to be held on               ,               , 1996, at
5:30 p.m., local time, at the Bank's main office. See "INTRODUCTION."
 
TERMS OF THE MERGER
 
     Upon the date of consummation of the Merger (the "Effective Date") and
subject to certain conditions, holders of the Bank's Common Stock will be
entitled to receive shares of BancGroup Common Stock and cash. On the Effective
Date, each share of Bank Common Stock issued and outstanding shall be converted
by operation of law into the right to receive the number of shares, or such
fractions of a share, of BancGroup Common Stock which shall be equal to
$2,600,000 divided by the total number of shares of Bank Common Stock
outstanding, divided in turn by the Market Value. 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
10 consecutive trading days ending on the trading day immediately preceding the
Effective Date. In addition, BancGroup will pay an aggregate of $2,600,000 in
cash for the outstanding shares of Bank Common Stock, with the amount of cash to
be paid for each share of Bank Common Stock equal to $2,600,000 divided by the
number of shares of Bank Common Stock outstanding. (The BancGroup Common Stock
to be issued and cash to be exchanged for Bank Common Stock as stated above is
sometimes referred to as the "Merger Consideration.") As of the date of this
Prospectus, there were 399,688 shares of Bank Common Stock outstanding.
 
     Stockholders of the Bank may elect, subject to the restrictions summarized
below, to receive their Merger Consideration in all cash or all shares of
BancGroup Common Stock, or some proportion that is other than 50% for each.
Stockholders must file an election form (a copy of which is enclosed with this
Prospectus) prior to the Special Meeting if they wish to have their Merger
Consideration paid in a proportion of BancGroup Common Stock and cash that is
other than 50-50. Regardless of such elections, however, the total amount of
BancGroup Common Stock to be issued in the Merger shall equal 50% of the total
Merger Consideration and the total amount of cash (including cash paid for
appraisal rights) shall equal 50%. Accordingly, stockholders of the Bank may be
paid Merger Consideration in a proportion that is other than 50-50 of BancGroup
Common Stock and cash, even if such stockholders have filed an election form
requesting Merger Consideration in some other proportion.
 
     No fractions of shares of Common Stock will be issued. Pursuant to the
Agreement, each holder of shares of Bank Common Stock who would otherwise be
entitled to receive a fraction of a share of BancGroup Common Stock shall
receive, in lieu of such fractional share, cash (without interest) in an amount
equal to such fractional share multiplied by the Market Value.
 
     As an example, a stockholder of the Bank who owns 500 shares of Bank Common
Stock would be entitled to receive for such shares BancGroup Common Stock and
cash. Assuming such stockholder receives BancGroup Common Stock and cash in the
proportion of 50-50 for each, assuming no exercise of appraisal
 
                                        6
<PAGE>   12
 
rights, and assuming a Market Value of BancGroup Common Stock at the Merger of
$32, then such stockholder would receive Merger Consideration as follows:

</TABLE>
 
- ---------------
 
(1) Each share of Bank Common Stock receives an amount of BancGroup Common Stock
     determined by the following formula: $2,600,000 / 399,688 / 32 = .203284.
     Thus, 500 shares multiplied by .203284 yields 101.64 BancGroup shares. The
     fraction of .64 of a share would be paid in cash.
(2) Determined by the following formula: $2,600,000 / 399,688 = $6.51 cash for
     each share of Bank Common Stock.
(3) The total Merger Consideration represents the $3252.55 of cash to be
     received plus the value of the 101.64 shares of BancGroup Common Stock to
     be received at a Market Value of $32 per share.
 
     See "APPROVAL OF THE MERGER -- Conversion of Bank Shares."
 
     The closing price of BancGroup Common Stock as reported on the NYSE as of
February 9, 1996 was $32 1/8 per share. See "COMPARATIVE MARKET PRICES AND
DIVIDENDS."
 
     Except as stated above, no adjustments will be made to the number of shares
of BancGroup Common Stock to be issued in the Merger based upon the operating
results, financial condition or other factors relating to either the Bank or
BancGroup. The actual number of shares to be issued will depend upon the Market
Value of the BancGroup Common Stock at the time of the Effective Date of the
Merger. The aggregate number of shares of BancGroup Common Stock issued in the
Merger will increase as the Market Value of such shares at the Effective Date of
the Merger decreases and will decrease as the Market Value increases. The amount
of cash to be paid will not vary based upon the earnings of the Bank or other
performance factors. See "APPROVAL OF THE MERGER -- Conversion of Bank Shares"
and "-- Certain Federal Income Tax Consequences."
 
     Bank stockholders will be given notice of consummation of the Merger
promptly after the Effective Date of the Merger. Certificates for the BancGroup
Common Stock issued and cash to be paid will not be distributed until
stockholders surrender their certificates representing Bank Common Stock. See
"APPROVAL OF THE MERGER -- Conversion of Bank Shares."
 
INTEREST OF CERTAIN PERSONS IN THE MERGER
 
     The Bank has entered into agreements with Charles Williams, president and
chief executive officer of the Bank, and Charles E. Myers, executive vice
president and controller of the Bank, pursuant to which each person could
receive cash payments following the Merger, should such persons terminate
employment with the Bank (or Colonial Bank following the Merger). The purpose of
these agreements is to provide incentives to each person to remain as officers
and employees of the Bank during the period of time that the Merger is pending.
 
REASONS FOR THE MERGER
 
     The Board of Directors of the Bank believes the Merger is in the best
interests of Bank stockholders. In recommending the Merger, the Board considered
a number of factors, including the market price of BancGroup Common Stock, the
dividend history of the BancGroup Common Stock, the lack of liquidity for the
Bank Common Stock, and the apparent and continued trend toward consolidation in
the banking field which may make it more difficult for the Bank to compete and
maintain profitability in the future. See "APPROVAL OF THE MERGER -- Reasons for
and Background of Merger."
 
                                        7
<PAGE>   13
 
VOTE REQUIRED
 
     Pursuant to OTS regulations, the Merger (item 1 on the proxy card) requires
the approval of at least two-thirds of the outstanding shares of Common Stock of
the Bank. Each share of Bank Common Stock is entitled to one vote per share. A
total of 399,688 shares are outstanding. Only those stockholders of the Bank who
were stockholders of record at the close of business on               , 1996,
are entitled to notice of and to vote at the Special Meeting. The Bank's
directors and executive officers own in the aggregate 210,549 shares
representing 52.68% of the outstanding shares of Common Stock of the Bank and
have agreed to vote for the Merger. Directors and executive officers of
BancGroup beneficially own in the aggregate 2,103,478 shares representing 15.35%
of the outstanding shares of Common Stock of BancGroup, but no vote of
BancGroup's stockholders is required for the Merger. See "INTRODUCTION" and
"BUSINESS OF THE BANK -- Principal Stockholders," and "Security Ownership of
Management."
 
     Proxies should be submitted in the envelope enclosed herewith. Stockholders
of the Bank submitting proxies may revoke their proxies by giving notice of such
revocation in writing to the person named in the Notice of Special Meeting of
Stockholders, by executing and delivering a proxy bearing a later date, or by
attending the Special Meeting and voting in person. Because approval of the
Merger requires the approval of at least two-thirds of the outstanding shares of
Common Stock of the Bank, 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
"INTRODUCTION -- Solicitation, Voting and Revocation of Proxies."
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
     Pursuant to regulations of the OTS, any stockholder of record of the Bank
may dissent from the Merger and obtain the fair value of his Common Stock in
cash if such stockholder (i) gives notice in writing to the Bank before voting
on the Merger that he intends to demand appraisal rights, (ii) does not vote in
favor of the Merger, and (iii) follows certain other procedures explained
further herein. Exercise of appraisal rights by stockholders will reduce the
$2,600,000 figure for determining the amount of cash to be issued in the Merger
by an amount equal to the number of shares exercising appraisal rights
multiplied by $13.01. See "APPROVAL OF THE MERGER -- Rights of Dissenting
Stockholders" and Appendix B hereto.
 
     Any stockholder who properly exercises appraisal rights and receives the
fair market value for his shares will encounter income tax treatment different
than the treatment for stockholders who do not exercise appraisal rights. See
"APPROVAL OF THE MERGER -- Certain Federal Income Tax Consequences."
 
     For certain information concerning dissenting stockholders' rights, voting
at the Special Meeting, and management of BancGroup and the Bank, see "APPROVAL
OF THE MERGER -- Rights of Dissenting Stockholders," "-- Conversion of Bank
Shares"; "INTRODUCTION -- Solicitation, Voting and Revocation of Proxies,"
"-- Record Date; Shares Entitled to Vote; Vote Required"; "BUSINESS OF
BANCGROUP -- Voting Securities and Principal Stockholders," "-- Security
Ownership of Management," and "BUSINESS OF THE BANK -- Principal Holders of
Common Stock," and "-- Security Ownership of Management."
 
CONDITIONS OF CONSUMMATION
 
     The Merger is subject to approval by the requisite vote of at least
two-thirds of the outstanding shares of Common Stock of the Bank, and certain
other conditions. The Merger must be approved by the Alabama State Banking
Department (the "Alabama Department"), the Office of Thrift Supervision ("OTS")
and the Federal Deposit Insurance Corporation ("FDIC"). Applications are
expected to be filed with these agencies within the next two weeks, and the
regulatory approval process is expected to take approximately five months. It is
anticipated that the foregoing conditions, as well as certain other conditions
contained in the Agreement, will be satisfied, but the Agreement states that the
Bank and BancGroup may waive all conditions to their obligations to consummate
the Merger, except that the conditions of the requisite approvals of regulatory
authorities and stockholder approval of the Merger may not be waived. Either
BancGroup or the Bank may terminate the Merger if the Merger is not consummated
by December 31, 1996. See "APPROVAL OF THE MERGER -- Conditions of Consummation
of the Merger."
 
                                        8
<PAGE>   14
 
     In addition, the Boards of Directors of BancGroup and the Bank may amend or
terminate the Agreement before or after approval by the stockholders of the
Bank. No amendments will be made to the Agreement which would alter the Merger
Consideration or which, in the opinion of the Board of Directors of the Bank,
would adversely affect the rights of the stockholders of the Bank. Any
amendments to the Agreement which in the opinion of the Board of Directors of
the Bank would have a material adverse effect upon the stockholders of the Bank
would be submitted to the Bank's stockholders for approval. Such amendments
could require the filing of an amendment of the Registration Statement, of which
this Prospectus forms a part, with the Commission.
 
     See "APPROVAL OF THE MERGER -- Conditions of Consummation of the Merger."
 
BUSINESS OF THE BANK
 
     The Bank is a federally chartered stock savings bank which began operations
in 1988. The Bank's primary business is to accept savings deposits from the
general public and to make real estate loans secured by residential and
commercial property and, to a lesser extent, to make commercial and consumer
loans. Its income is derived from interest and fees in connections with such
loans. The Bank's principal expenses are interest paid on deposits and operating
expenses. The Bank conducts business through one office in Dothan, Alabama. See
"BUSINESS OF THE BANK."
 
BUSINESS OF BANCGROUP
 
     BancGroup conducts a commercial banking business in the states of Alabama,
Tennessee and Georgia through 98, four and four banking offices, respectively.
Colonial Mortgage Company, a subsidiary of BancGroup's Alabama bank subsidiary,
Colonial Bank, is a mortgage company that has $9 billion of residential loan
servicing and 13 offices in 12 states. As of September 30, 1995, BancGroup had
consolidated assets of $3.4 billion and consolidated shareholders' equity of
$223 million. BancGroup has entered into agreements to acquire an additional
bank in Alabama and to acquire a bank in Orlando, Florida. See "BUSINESS OF
BANCGROUP" and "PRO FORMA INFORMATION."
 
COMMON STOCK OF THE BANK
 
     The holders of Common Stock of the Bank are entitled to dividends as and
when declared by the Board of Directors out of funds legally available therefor,
to one vote for each share held on matters submitted to a vote of stockholders,
and, in the event of liquidation, to the net assets remaining after satisfaction
of all liabilities. As of               , 1996, the Bank had 399,688 shares of
its Common Stock outstanding and 196 stockholders of record. See "COMPARATIVE
RIGHTS OF STOCKHOLDERS."
 
COMMON STOCK OF BANCGROUP
 
     BancGroup is authorized to issue 44,000,000 shares of its Common Stock, of
which on January 31, 1996, 13,491,691 shares were issued and outstanding.
Further, up to 345,321 shares of Common Stock are issuable upon conversion of
certain debentures of BancGroup and 214,957 shares are subject to issue upon
exercise of outstanding options under BancGroup's stock option plans. BancGroup
has authorized 1,000,000 shares of Preference Stock, none of which has been
issued. Certain provisions of BancGroup's Restated Certificate of Incorporation
and bylaws may have the effect of preventing, delaying or deferring a change in
control of BancGroup. Among other things, these provisions include the election
of the BancGroup Board of Directors on a classified basis, supermajority votes
of stockholders to approve certain business combinations, and the inability of
stockholders to call special meetings or to act by written consent.
 
     See "BANCGROUP CAPITAL STOCK AND DEBENTURES," and "COMPARATIVE RIGHTS OF
STOCKHOLDERS."

<PAGE>   15
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     No ruling with respect to the federal income tax consequences of the Merger
to the Bank's stockholders will be requested from the Internal Revenue Service
(the "IRS"). BancGroup and the Bank have received an opinion from counsel to
BancGroup, Miller, Hamilton, Snider & Odom, L.L.C., Mobile, Alabama, that, among
other things, a stockholder of the Bank who exchanges shares of Bank Common
Stock for BancGroup Common Stock and cash shall recognize gain, if any, but only
in an amount not in excess of the sum of such cash received. Also, stockholders
of the Bank will also recognize gain to the extent such stockholders receive
cash in lieu of fractional shares of BancGroup Common Stock or who receive cash
pursuant to the exercise of their dissenting stockholders' rights. See "APPROVAL
OF THE MERGER -- Certain Federal Income Tax Consequences."
 
ACCOUNTING TREATMENT
 
     The acquisition of the Bank 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, approximating $1,574,000,
will be amortized by charges or credits to future earnings over a period
approximating 20 years. See "APPROVAL OF THE MERGER -- Accounting Treatment."
 
RECENT PER SHARE MARKET PRICE
 
     The Bank.  There is no established public trading market for the Common
Stock of the Bank. To the knowledge of the Bank, 10,518 shares of the Bank
Common Stock have been transferred since January 1, 1994. The Bank has no
knowledge of the sales prices, if any, in such transfers. See "COMPARATIVE
MARKET PRICES AND DIVIDENDS -- The Bank."
 
     BancGroup.  BancGroup Common Stock is listed for trading on the NYSE under
the System symbol "CNB."
 
     The following table indicates the high and low closing prices of the
BancGroup Class A Common Stock and the BancGroup Common Stock as reported on the
Nasdaq National Market and the NYSE for the last two full fiscal years. Prior to
February 21, 1995, BancGroup had two classes of Common Stock outstanding, Class
A and Class B. Class B was not publicly traded. Class A was traded as a Nasdaq
National Market security under the symbol "CLBGA" until February 24, 1995. On
February 21, 1995, the Class A and Class B Common Stock were reclassified into
Common Stock.

(3) If the Merger had closed on, November 21, 1995, .2230 (6.5051/29.175) shares
     of BancGroup Common Stock would have been exchanged for each one share of
     the Bank Common Stock, and $6.50 in cash would also have been paid for such
     share, assuming 399,688 shares of Bank Common Stock outstanding, no
     exercise of dissenters' rights of appraisal, and a 50-50 distribution of
     stock and cash for each one share of Bank Common Stock.

CERTAIN LEGAL RESTRICTIONS ON ACQUISITIONS OF CONTROL
 
     Certain restrictions under Delaware law prevent a person who beneficially
owns 15% or more of BancGroup's 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 vote 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.

     Federal Savings Bank. For the purposes of these pro forma equivalent per             
     share amounts, a .2045 BancGroup common stock share conversion ratio is              
     utilized. The ratio is based on the 10-day average market price of Colonial          
     BancGroup, Inc. common stock of $31.8125 at January 9, 1996.                         
                                                                                          
 (c) Pro forma equivalent dividends per share are shown at BancGroup's Class A      
     Common Stock dividend per share rate multiplied by the .2045 conversion        
     ratio per share of Dothan Federal Savings Bank 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.

                                  INTRODUCTION
 
GENERAL
 
     This Prospectus is being furnished to the stockholders of the Bank in
connection with the solicitation of proxies by the Board of Directors of the
Bank for use at a Special Meeting of stockholders to be held on             ,
1996, at 5:30 p.m., local time, and at any adjournments thereof (the "Special
Meeting"), as stated in the accompanying Notice of Special Meeting of
Stockholders and described herein. The purpose of the Special Meeting is to
consider and vote upon the proposed Merger of the Bank with and into Colonial
Bank, BancGroup's Alabama bank subsidiary. Colonial Bank 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 the Bank believes that the Merger is in the best
interests of the Bank and its stockholders and unanimously recommends that
stockholders vote "FOR" the Merger (item 1 on the proxy card). Each member of
the Board of Directors of the Bank has separately agreed with BancGroup to vote
his or her shares in favor of the Merger.
 
RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED FOR THE MERGER
 
     Shares of Common Stock, par value $.01 per share, are the only securities
of the Bank issued and outstanding. The close of business on             , 1996,
has been fixed by the Board of Directors of the Bank as the record date for
determination of stockholders entitled to vote at the Special Meeting. There
were 196 record holders of Bank Common Stock as of such date. On that date,
there were outstanding 399,688 shares of Common Stock of the Bank. Approval of
the Merger requires the affirmative vote of at least two-thirds of the
outstanding shares of Common Stock of the Bank. Each share is entitled to one
vote.
 
     Under federal regulations, stockholders of the Bank have dissenters' rights
of appraisal with respect to the Merger. See "APPROVAL OF THE MERGER -- Rights
of Dissenting Stockholders."
 
     If the Merger is approved at the Special Meeting, the Bank is expected to
merge with and into Colonial Bank promptly after the other conditions to the
Agreement are satisfied. See "APPROVAL OF THE MERGER -- Conditions of
Consummation of the Merger." If the Merger is not approved at the Special
Meeting and it becomes reasonably and objectively certain that stockholder
approval cannot be obtained or the other conditions to the Agreement are not
satisfied, the Merger will be terminated.
 
     THE BOARD OF DIRECTORS OF THE BANK URGES THE STOCKHOLDERS OF THE BANK 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
MERGER.
 
SOLICITATION, VOTING AND REVOCATION OF PROXIES
 
     In addition to soliciting proxies by mail, directors, officers, and other
employees of the Bank, without receiving special compensation therefor, may
solicit proxies from the Bank's stockholders by 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 Common Stock of the Bank held of record by
such persons.
 
     The cost of mailing this Prospectus and other materials furnished to
stockholders of the Bank and all other expenses of solicitation, including the
expenses of brokers, custodians, nominees, and other fiduciaries who, at the
request of the Bank, mail material to or otherwise communicate with beneficial
owners of the shares held by them, will be paid by the Bank. Expenses incident
to the registration of the securities to be issued in connection with the Merger
will be paid by BancGroup.
 
                                       14
<PAGE>   20
 
     Each proxy which is solicited on behalf of the Bank, as stated on such
proxy, permits each record holder of Common Stock of the Bank to vote on the
Merger. Where a stockholder specifies his or her choice on the proxy with
respect to the Merger, the shares represented by the proxy will be voted in
accordance with such specification. IF NO SUCH SPECIFICATION IS MADE, THE SHARES
WILL BE VOTED IN FAVOR OF THE MERGER. Properly executed proxies will be voted in
accordance with the determination of a majority of the Board of Directors of the
Bank as to any other matter which may properly come before the Special Meeting.
The enclosed proxy card should be returned in the accompanying envelope.
 
     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 be counted for purposes of determining a quorum at
the Special Meeting. Stockholders who execute proxies retain the right to revoke
them at any time. However, abstentions and broker non-votes will have the same
effect as a "no" vote respecting stockholder approval of the Merger.
 
     A proxy may be revoked at any time before it is voted by: (i) filing with
the Secretary of the Bank a written notice of revocation, (ii) delivering to the
Bank a duly executed proxy bearing a later date; or (iii) attending the Special
Meeting and voting in person. Attendance at the Special Meeting will not in and
of itself constitute revocation of the proxy.
 
     The Board of Directors of the Bank is not aware of any business to be acted
upon at the Special Meeting other than consideration of the Merger described
herein.
 
VOTING EFFECT OF MERGER
 
     Assuming that (i) no dissenters' rights of appraisal are exercised in
connection with the Merger and (ii) a Market Value of BancGroup's Common Stock
of $32 per share, upon consummation of the Merger (a) 81,250 shares of BancGroup
Common Stock will be issued and $2,600,000 in cash will in the aggregate be paid
in connection with the Merger and (b) former holders of Bank Common Stock will
hold 81,250 shares, or .60%, of the BancGroup Common Stock then outstanding.
 
                             APPROVAL OF THE MERGER
 
     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, A COPY OF WHICH IS ATTACHED HERETO AS APPENDIX A, AND CERTAIN
REGULATIONS OF THE OTS RELATING TO THE RIGHTS OF DISSENTING STOCKHOLDERS, A COPY
OF WHICH IS ATTACHED HERETO AS APPENDIX B. ALL BANK STOCKHOLDERS ARE URGED TO
READ ALL APPENDICES IN THEIR ENTIRETY.
 
GENERAL
 
     Pursuant to the Agreement, subject to stockholder approval, receipt of
necessary regulatory approval and certain other conditions set forth in the
Agreement, the Bank will merge with and into Colonial Bank, a wholly-owned
Alabama bank subsidiary of BancGroup. Upon completion of the Merger, the
corporate existence of the Bank will cease, and Colonial Bank will succeed to
the business formerly conducted by the Bank.
 
     In the event there is an insufficient number of shares of Bank Common Stock
present in person or by proxy at the Special Meeting to approve the Merger, the
Board of Directors of the Bank intends to adjourn the Special Meeting. Any such
adjournment will require the affirmative vote of a majority of shares present at
the Special Meeting. While such an adjournment would not invalidate any proxies
previously filed, including those filed by stockholders voting against the
Merger, it would give the Bank the opportunity to solicit additional proxies in
favor of the Merger.

     In March, 1995, BancGroup contacted representatives of the Bank about a
possible acquisition of the Bank. At that time, the Bank did not enter into
negotiations regarding such an acquisition. In August, 1995, the Bank retained
the services of T. Stephen Johnson & Associates, a financial brokerage firm, to
seek possible buyers of the Bank. In September 1995, such broker contacted
BancGroup to determine whether BancGroup would have an interest in the Bank.
Approximately 24 potential purchasers of the Bank were contacted, and ten
expressed interest to the Bank in an acquisition. BancGroup was the only
institution making an offer of acquisition. The Bank's Board of Directors
decided that the BancGroup proposal represented the best transaction for the
Bank's stockholders. Following negotiations, the Bank and BancGroup entered into
a letter of intent on November 17, 1995, stating the intent of the parties to
merge the Bank with Colonial Bank. Following further discussions and a review of
the Bank's finances and operations by BancGroup, the Agreement was executed in
late January, 1996.
 
     In negotiating the letter of intent and the Agreement, Bank management
wanted an opportunity for the stockholders of the Bank to be paid cash for their
Bank Common Stock. Although the Common Stock of BancGroup represents a liquid
security that may be readily sold on the NYSE, Bank management believed that the
opportunity for Bank stockholders to receive cash in the Merger was important.
At the same time, Bank stockholders have an opportunity in the Merger to receive
BancGroup Common Stock that, unlike the Bank Common Stock for which there is no
active trading market, may be traded on the NYSE.
 
     The Bank also considered the market value of the BancGroup Common Stock and
the dividend history of BancGroup.
 
     In approving the Agreement, the Board of Directors of the Bank also
considered the general trend in the banking industry toward consolidations and
mergers between community and regional banks. The Board believes that new
interstate banking legislation may result in increased consolidation in the
banking industry and may make it more difficult for smaller community banks,
such as the Bank, to compete in a given market area with larger, better
capitalized banks. With such increased competition, the upgrading of customer
services and products that would probably be necessary for the Bank would
necessitate additional personnel and overhead costs, both of which could
significantly reduce the Bank's profitability.
 
     Finally, the Board considered the management philosophy of
BancGroup -- i.e., an emphasis upon local input and judgment in the operations
of its branch banks -- to be important in serving the Bank's customers.
 
     In reaching its decision to approve the Merger, the Board of Directors did
not place a relative weight on any of the foregoing factors, but concluded that
in light of all of the foregoing, the merger is in the best interests of the
Bank's stockholders.
 
     The Merger will also enable BancGroup to expand its banking operations in
southeast Alabama in locations where BancGroup has not previously had branch
banking offices.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Charles Williams, president and chief executive officer of the Bank, and
Charles E. Myers, vice president and controller, each entered into agreements
with the Bank, dated October 22, 1995, and expiring October 1, 1996, which
provide that in the event of a change in control of the Bank, each person will
be entitled for a period of 180 days from the date of closing the change in
control transaction to terminate such agreements and receive a lump sum cash
payment, in the case of Mr. Williams, of $32,000, and in the case of Mr. Myers
of $22,000. Mr. Williams is also entitled to receive his Bank-furnished
automobile. Among other things, a "change in control" is defined as a merger of
the Bank in which any person acquires control of 50% or more of the Bank's
Common Stock. The agreements were entered into by the Bank to provide incentives
to Mr. Williams and Mr. Myers to remain as officers and employees of the Bank
during the time that the Bank was actively considering a sale. The Merger
constitutes a change in control of the Bank.

CONVERSION OF BANK SHARES
 
     Merger Consideration.  On the effective date of the Merger (the "Effective
Date"), and except as stated below, each share of the Bank's Common Stock
outstanding and held of record by Bank stockholders shall be converted by
operation of law into the right to receive shares of BancGroup Common Stock and
cash upon surrender of the certificates representing shares of Bank Common
Stock. Each outstanding share of Bank Common Stock shall be converted into the
number of shares, or such fractions of a share, of BancGroup Common Stock which
shall be equal to $2,600,000 divided by the total number of shares of Bank
Common Stock outstanding, divided in turn by the Market Value. 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 10 consecutive trading days ending on the trading day immediately
preceding the Effective Date. In addition, BancGroup will pay an aggregate of
$2,600,000 in cash for the outstanding shares of Bank Common Stock, with the
amount of cash to be paid for each share of Bank Common Stock equal to
$2,600,000 divided by the number of shares of Bank Common Stock outstanding.
(The BancGroup Common Stock to be issued and the cash to be paid in exchange for
Bank Common Stock as stated above is sometimes referred to as the "Merger
Consideration.") The closing price of the BancGroup Common Stock on the NYSE on
February 9, 1996, was $32 1/8 per share. As of the date of this Prospectus,
there were 399,688 shares of Bank Common Stock outstanding.
 
     No fractions of shares of BancGroup Common Stock will be issued in the
Merger. Pursuant to the Agreement, each holder of shares of Bank Common Stock
who would otherwise be entitled to receive a fraction of a share of BancGroup
Common Stock shall receive, in lieu of such fractional share, cash (without
interest) in an amount equal to such fraction of a share multiplied by the
Market Value.
 
     As an example, a stockholder of the Bank who owns 500 shares of Bank Common
Stock would be entitled to receive for such shares BancGroup Common Stock and
cash. Assuming such stockholder receives BancGroup Common Stock and cash in the
proportion of 50-50 for each, assuming no exercise of appraisal rights, and
assuming a Market Value of BancGroup Common Stock at the Merger of $32, then
such stockholder would receive Merger Consideration as follows:

- ---------------
 
(1) Each share of Bank Common Stock receives an amount of BancGroup Common Stock
     determined by the following formula: $2,600,000 / 399,688 / 32 = .203284.
     Thus, 500 shares multiplied by .203284 yields 101.64 BancGroup shares. The
     fraction of .64 of a share would be paid in cash.
(2) Determined by the following formula: $2,600,000 / 399,688 = $6.51 cash for
     each share of Bank Common Stock.
(3) The total Merger Consideration represents the $3252.55 of cash to be
     received plus the value of the 101.64 shares of BancGroup Common Stock to
     be received at a Market Value of $32 per share.
 
     If any stockholder of the Bank exercises dissenters' rights of appraisal
and receives cash for Bank Common Stock held, the $2,600,000 figure stated above
which is to be used for calculating the cash to be distributed shall be reduced
by an amount that equals the number of shares of Bank Common Stock properly
exercising dissenting rights of appraisal multiplied by $13.01. See "Rights of
Dissenting Stockholders."
 
     Election Forms.  A holder of Bank Common Stock may, prior to the Special
Meeting, file a written election form (an "Election Form") with the Bank
specifying whether such holder prefers to have the Merger Consideration paid to
such holder in shares of BancGroup Common Stock only, cash only, or a proportion
of cash and BancGroup Common Stock that is other than 50% for each, provided
that, notwithstanding any elections made pursuant to such Election Forms, the
aggregate number of shares of BancGroup Common
 
                                       17
<PAGE>   23
 
Stock to be distributed in the Merger shall equal 50% of the total Merger
Consideration and the aggregate amount of cash to be paid in the Merger shall
equal 50% of the total Merger Consideration. An Election Form shall apply to all
shares of record of Bank Common Stock held by the holder of record submitting
the Election Form. An Election Form is enclosed with this Prospectus.
 
     If the aggregate amount of cash to be paid in the Merger is less than 50%
of the Merger Consideration based upon the Election Forms which have been
properly filed, then a sufficient amount of additional cash shall be distributed
pro rata to all stockholders of the Bank who have not elected to receive 100% of
the Merger Consideration in cash, regardless of whether such stockholders have
filed an Election Form, so that the aggregate amount of Merger Consideration to
be paid in cash in the Merger will equal 50%, and the number of shares of
BancGroup Common Stock otherwise required to be distributed shall be reduced pro
rata as to all stockholders who have not elected to receive 100% of the Merger
Consideration in cash.
 
     If the aggregate amount of cash to be paid in the Merger is greater than
50% of the Merger Consideration based upon the Election Forms which have been
properly filed, then the aggregate amount of cash will be reduced and a
sufficient amount of cash shall be distributed pro rata to all stockholders of
the Bank who have not elected to receive 100% of the Merger Consideration in
BancGroup Common Stock, regardless of whether such stockholders have filed an
Election Form, so that the aggregate amount of Merger Consideration to be paid
in cash in the Merger will equal 50%, and the number of shares of BancGroup
Common Stock otherwise required to be distributed shall be increased pro rata as
to all stockholders who have not elected to receive 100% of the Merger
Consideration in BancGroup Common Stock. Cash to be paid to holders exercising
dissenter's rights of appraisal shall be included as part of the Merger
Consideration for determining the amount of cash to be paid in the Merger.
Interest will not be paid on any cash to be paid as part of the Merger
Consideration.
 
     Deadline for Election Forms.  The Election Form may be submitted to the
Bank along with the proxy in the envelope which has been provided with this
Prospectus. ELECTION FORMS MUST BE RECEIVED BY THE BANK NO LATER THAN 5:30 P.M.
ON             , 1996, THE START OF THE SPECIAL MEETING.
 
     Surrender of Certificates and Dividends.  Upon the Effective Date and
subject to the conditions described at "Conditions of Consummation of the
Merger," the Bank's stockholders will automatically, and without further action
by such stockholders or by BancGroup, have the right to receive shares of
BancGroup Common Stock and cash upon surrender of the certificates representing
their shares of Bank Common Stock as described herein. Outstanding certificates
representing shares of Bank Common Stock shall represent the right to receive
shares of Common Stock of BancGroup and cash. Thereafter, upon surrender of the
certificates formerly representing shares of Bank Common Stock, the holder will
receive certificates for the Common Stock of BancGroup and the cash payment to
which such person is entitled. Dividends on the shares of BancGroup Common Stock
will accumulate without interest and will not be distributed to any former
stockholder of the Bank unless and until such stockholder surrenders for
cancellation his certificates for Bank Common Stock. No interest will be paid on
the cash to be distributed in the Merger. Trust Company Bank, Atlanta, Georgia,
transfer agent for BancGroup Common Stock, will act as the Exchange Agent with
respect to the shares of Bank Common Stock surrendered and cash paid in
connection with the Merger.
 
     A detailed explanation of these arrangements will be mailed to Bank
stockholders promptly following the Effective Date. STOCK CERTIFICATES FOR BANK
COMMON STOCK SHOULD NOT BE SENT TO THE EXCHANGE AGENT UNTIL SUCH NOTICE IS
RECEIVED.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion is a summary of certain anticipated material
federal income tax consequences of the Merger to the Bank and the Bank
stockholders who are citizens of the United States. It does not discuss all the
tax consequences that may be relevant to the Bank stockholders entitled to
special treatment under the Internal Revenue Code of 1986, as amended (the
"Code") (such as insurance companies, dealers in securities, tax-exempt
organizations or foreign persons) or to Bank stockholders who acquired their
Bank Common Stock pursuant to the exercise of employee stock options or
otherwise as compensation. The summary set forth below does not purport to be a
complete analysis of all potential tax effects of the
 
                                       18
<PAGE>   24
 
transactions contemplated by the Agreement or the Merger itself. EACH BANK
STOCKHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX AND FINANCIAL ADVISOR AS TO
THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER ON HIS OR HER OWN PARTICULAR
FACTS AND CIRCUMSTANCES, AND ALSO AS TO ANY STATE, LOCAL, FOREIGN OR OTHER TAX
CONSEQUENCES ARISING OUT OF THE MERGER.
 
     No ruling has been or will be requested from the Internal Revenue Service
("IRS") as to any of the federal income tax effects to the Bank stockholders of
the Merger or the federal income tax effects to the Bank. Instead, the Bank is
relying upon an opinion of BancGroup's special counsel, Miller, Hamilton, Snider
& Odom, L.L.C., as to the federal income tax consequences of the Merger to the
Bank stockholders and to the Bank.
 
     Based upon the opinion of Miller, Hamilton, Snider & Odom, L.L.C., which
relies upon various representations and is subject to various assumptions and
qualifications, including that the Merger is consummated in the manner and
according to the terms provided in the Agreement, the following federal income
tax consequences to the Bank stockholders and to the Bank will result from the
Merger. The tax opinion is based upon certain assumptions, including the
assumption that the Bank has no knowledge of any plan or intention on the part
of the Bank stockholders 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 Bank Common
Stock outstanding immediately upon the Merger. The following presents a summary
of that opinion:
 
          1. The Merger will qualify as a reorganization within the meaning of
     Section 368(a)(1) pursuant to Section 368(a)(2)(D) of the Code.
 
          2. A Bank stockholder who exchanges shares of Bank Common Stock solely
     for BancGroup Common Stock pursuant to the election provided in the
     Agreement, will not recognize any gain or loss.
 
          3. No gain or loss will be recognized by the Bank as a result of the
     Merger.
 
          4. A Bank stockholder who exchanges shares of Bank Common Stock for a
     combination of BancGroup Common Stock and cash, as described in the
     Agreement, shall recognize gain. The amount of the gain realized by a
     stockholder will be the excess of (a) the sum of (i) the amount of cash
     received, and (ii) the fair market value of shares of BancGroup Common
     Stock received, over (b) the tax basis of the shares of Bank Common Stock
     exchanged therefor. Of such gain realized, a stockholder will recognize
     gain, but limited to the amount of cash received. No loss shall be
     recognized. Any gain recognized by such stockholders of the Bank will be
     characterized as capital gain if the Bank Common Stock is a capital asset
     in the hands of such stockholders and their receipt of the cash does not
     have "the effect of the distribution of a dividend" within the meaning of
     Section 356(a)(2) of the Code, as interpreted by the United States Supreme
     Court in Commission v. Clark, 489 U. S. 726 (1989). Otherwise, the receipt
     of the cash will be treated as a dividend. Pursuant to Clark, such Bank
     stockholders will be treated as if the stockholder received only BancGroup
     Common Stock and then BancGroup redeemed a portion of such Common Stock for
     the amount of cash that actually was issued (a post-reorganization
     hypothetical redemption). If that hypothetical redemption satisfies any of
     the tests of Section 302(b) of the Code, it will be treated as an exchange.
     Bank stockholders should be able to satisfy one or more of the tests for
     exchange treatment under of Section 302(b) of the Code. Consequently, any
     gain recognized by a Bank stockholder should be treated as capital gain or
     loss. However, the application of Section 302(b) is dependent on each
     stockholder's particular facts and circumstances and is affected by the
     attribution rules of Section 318 of the Code. Consequently, Bank
     stockholders should seek independent tax advice as to the tax effect of the
     Merger including the receipt of the cash, to them.
 
          5. A Bank stockholder who exchanges Bank Common Stock solely for cash
     pursuant to an election provided in the Agreement shall recognize gain or
     loss. The amount of the gain realized by such stockholder will be the
     excess of the amount of cash received over the tax basis of the shares of
     Bank Common Stock exchanged therefor. Any gain recognized by such
     stockholders of the Bank will be
 
                                       19
<PAGE>   25
 
     characterized as capital gain if the Bank Common Stock is a capital asset
     in the hands of such stockholders and receipt of the cash does not have the
     "effect of the distribution of a dividend" within the meaning of Section
     356(a)(2) of the Code. It is unclear whether the post-reorganization
     hypothetical redemption of the Clark case discussed above will be
     applicable to such stockholders. Nonetheless, such stockholders should be
     entitled to capital gain treatment if the redemption satisfies any of the
     tests of Section 302(b) of the Code. Such Bank stockholders should be able
     to satisfy one or more of the tests for exchange treatment under Section
     302(b) of the Code. However, the application of Section 302(b) is dependent
     upon each stockholder's particular facts and circumstances and is affected
     by the attribution rules of Section 318 of the Code. Consequently, such
     Bank stockholders should seek independent tax advice as to the tax effects
     of the Merger, including the receipt of the cash, to them.
 
          6. The payment of cash to a Bank stockholder in lieu of a fractional
     share of BancGroup Common Stock as part of the Merger will be treated as if
     the fractional share was delivered to the stockholder and then redeemed by
     BancGroup, with the tax effect of such deemed redemption being determined
     under Section 302(b) of the Code.
 
          7. A Bank stockholder who dissents and receives only cash pursuant to
     dissenter's rights of appraisal 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 Bank Common Stock converted, if the shares of Bank Common Stock
     were held as capital assets. However, a Bank stockholder who receives only
     cash may need to consider the effects of Sections 302 and 318 of the Code
     in determining the federal income tax consequences of the transaction.
 
          8. The basis of the BancGroup Common Stock (including any fractional
     share) received by a Bank stockholder in the Merger will be the same as the
     basis of the Bank Common Stock surrendered in exchange therefor, decreased
     by the amount of cash received, and increased by the amount treated as a
     dividend and the amount of gain recognized on the exchange.
 
          9. The holding period of the BancGroup Common Stock received by a Bank
     stockholder in the Merger will include the holding period of the Bank
     Common Stock surrendered in exchange therefor, provided such shares of Bank
     Common Stock were capital assets or property described under Section 1231
     of the Code in the hands of the Bank stockholder on the day of the Merger,
     and otherwise will begin on the date following the date of the Merger.
 
     If the assumption stated above, that there is no plan or intention by the
Bank stockholders to sell or dispose of BancGroup Common Stock that would reduce
their holdings to the number of shares with an aggregate fair market value of at
least 50 percent of the total fair market value of Bank Common Stock outstanding
immediately before the Merger, were to be incorrect, then counsel would not be
able to opine that the Merger is a reorganization under Section 368 of the Code.
Accordingly, the Merger must satisfy the "continuity of interest" requirement
contained in Treasury Regulations and in judicial authority. The IRS has stated
that, for ruling purposes, for mergers to qualify as reorganizations, the
stockholders of the acquired corporation must receive and retain stock of the
acquiror equal to 50 percent of the aggregate fair market value of the acquired
corporation immediately before the Merger. Thus, of the total consideration
received by the stockholders of the Bank, at least 50% must consist of BancGroup
Common Stock. Moreover, Bank stockholders must retain at least that amount of
BancGroup stock after the Merger.
 
     The "continuity of interest" test may be affected by actions of the Bank's
stockholders subsequent to the Merger. If shares of BancGroup Common Stock
received in the Merger are sold after the Merger, for example, within a twelve
month period, the IRS may challenge the status of the Merger as a reorganization
under Section 368 of the Code. For example, if ten percent of such shares were
sold within such twelve month period pursuant to a pre-arranged plan or
commitment by any one or more Bank stockholders, the IRS might assert that there
was insufficient continuity by the Bank stockholders. If the IRS were successful
in that assertion, the Merger would be taxable to both the Bank and its
stockholders. As a result, Bank stockholders would be subject to gain or loss on
the entire transaction, including the receipt of BancGroup stock.
 
                                       20
<PAGE>   26
 
     As noted above, for advance ruling purposes the IRS requires fifty percent
continuity. However, that is not a rule of substantive law. Rather, it is the
minimum required by the IRS for issuance of Private Rulings to taxpayers that
request such rulings prior to consummating a transaction. Courts, however, have
upheld the status of mergers as reorganizations where continuity was less than
fifty percent.
 
     The opinion of Miller, Hamilton, Snider & Odom, L.L.C., is based entirely
upon the Code, regulations now in effect thereunder, current administrative
rulings and practice, and judicial authority, all of which are subject to
change. Unlike a ruling from the IRS, an opinion of counsel is not binding on
the IRS and there can be no assurance, and none is hereby given, that the IRS
will not take a position contrary to one or more positions reflected herein or
that the opinion will be upheld by the courts if challenged by the IRS.
 
OTHER POSSIBLE CONSEQUENCES
 
     If the Merger becomes effective, the stockholders of the Bank, a federal
savings bank, will exchange their shares of Common Stock for securities in a
Delaware business corporation.
 
     The state tax consequences, where applicable, of owning stock of a Delaware
business corporation may be different from those of owning shares of a federal
savings bank.
 
     For a discussion of the differences, if any, in the rights, preferences,
and privileges attaching to Bank Common Stock as compared with BancGroup Common
Stock, see "COMPARATIVE RIGHTS OF STOCKHOLDERS."
 
CONDITIONS OF CONSUMMATION OF THE MERGER
 
     Consummation of the Merger is subject to a number of conditions. First, the
Agreement must be approved by the affirmative vote of at least two-thirds of the
outstanding shares of Common Stock of the Bank.
 
     The Merger must also be approved by the Alabama State Banking Department
(the "Alabama Department"), the Office of Thrift Supervision ("OTS") and the
Federal Deposit Insurance Corporation ("FDIC"). Applications for approval are
expected to be filed with these agencies within the next two weeks, and the
regulatory approval process is expected to take approximately five months. Any
of these agencies might refuse or revoke approval or condition approval on one
or more of the parties agreeing to take some action such as making some change
in operations. The Bank Merger Act imposes a waiting period which prohibits
consummation of the Merger, in ordinary circumstances, for a period ranging from
15-30 days following the FDIC'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.
 
     The obligations of the Bank and BancGroup to consummate the Merger are
conditioned upon, among other things, (i) 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, (ii) the absence of any investigation by any
governmental agency which might result in any such proceeding, (iii)
consummation of the Merger no later than December 31, 1996, and (iv) receipt of
a favorable opinion of counsel to BancGroup regarding certain federal income tax
consequences of the Merger.
 
     The mutual obligations of the Bank and BancGroup to consummate the Merger
are further conditioned upon, among other things, (i) the accuracy in all
material respects of the representations and warranties of the Bank and
BancGroup contained in the Agreement, and the performance by the Bank and
BancGroup of all covenants and agreements of the Bank and BancGroup; (ii) the
absence of any material adverse changes in the results of operations and
financial condition of the Bank and BancGroup, except as may be disclosed in the
Agreement; and (iii) in the case of BancGroup's obligations, receipt by
BancGroup of certain undertakings from holders of the Bank Common Stock who may
be deemed to be "affiliates" of the Bank pursuant to the rules of the Securities
and Exchange Commission (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,
 
                                       21
<PAGE>   27
 
will be satisfied, but the Agreement states that the Bank and BancGroup may
waive all conditions to their obligations to consummate the Merger, except that
the conditions of the requisite approvals of regulatory authorities and Bank
stockholder approval of the Merger may not be waived. In making any decisions
regarding a waiver of one or more conditions to consummation of the Merger or an
amendment of the Agreement, the Board of Directors of the Bank would be subject
to fiduciary duty standards imposed upon such board by relevant law that would
require such Board to act in the best interests of the Bank's stockholders.
 
AMENDMENT AND TERMINATION
 
     The Boards of Directors of BancGroup and the Bank may amend or terminate
the Agreement before or after approval by the stockholders of the Bank. No
amendments will be made to the Agreement which would alter the Merger
Consideration or which, in the opinion of the Board of Directors of the Bank
would adversely affect the rights of the stockholders of the Bank. Any
amendments to the Agreement which in the opinion of the Board of Directors of
the Bank would have a material adverse effect upon the stockholders of the Bank
would be submitted to the Bank's stockholders for approval. Such amendments
could require the filing of an amendment of the Registration Statement, of which
this Prospectus forms a part, with the Commission.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
     The Agreement contains certain restrictions on the conduct of the business
of the Bank pending consummation of the Merger. In particular, prior to the
Effective Date, the Agreement prohibits the Bank from taking any of the
following actions, 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);
 
          (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

     Until the termination of the Agreement, neither the Bank nor any of its
directors or officers (or any person representing any of the foregoing) shall
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, the Bank or any business
combination involving the Bank other than as contemplated by the Agreement. The
Bank will notify BancGroup immediately if any such inquiries or proposals are
received by the Bank, if any such information is requested from the Bank, or if
any such negotiations or discussions are sought to be initiated with the Bank.
The Bank shall instruct its officers, directors, agents or affiliates or their
subsidiaries to refrain from doing any of the above; provided, however, that
nothing contained in the Agreement shall be deemed to prohibit any officer or
director of such party from fulfilling his fiduciary duty or from taking any
action that is required by law, and provided further that nothing in the
foregoing clause shall be deemed a waiver by BancGroup that any action taken by
the Bank pursuant to such proviso constitutes a breach of the Agreement.
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
     Stockholders of record of the Bank have certain appraisal rights under
Federal law relating to the Merger. OTS regulation 12 C.F.R. sec. 552.14
provides for rights of appraisal for the value of the shares of such stockholder
who (1) has given notice in writing to the Bank prior to voting upon the Merger
that he or she intends to exercise appraisal rights and demand appraisal for his
or her Bank Common Stock and (2) does not vote in favor of the Merger. Failure
of a stockholder to give such written notice or to follow properly any provision
of this regulation will result in a waiver of his or her rights of appraisal.
Such notice must identify the stockholder and state that the stockholder intends
to demand appraisal of and payment for his or her shares. Such written notice
must be in addition to and separate from any proxy or vote against the Merger by
the stockholder.
 
     Within 10 days of the consummation of the Merger, Colonial Bank will give
written notice of the Effective Date to the stockholders who dissented from the
Merger and will make a written offer to such stockholders to pay for their
shares at a specified price deemed by Colonial Bank to be the fair value thereof
and outlining other applicable procedures.
 
     If within 60 days after the Effective Date the fair value of such shares is
agreed upon between Colonial Bank and a dissenting Bank stockholder, payment
therefor shall be made within 90 days after the Effective Date upon the
surrender of the certificate representing such stockholder's shares of Bank
Common Stock.
 
     If within such period of 60 days a dissenting stockholder and Colonial Bank
do not agree, then such stockholder may file a petition with the OTS, 1700 G.
Street, N.W., Washington, D.C. 20552, attention: Director, with a copy filed by
certified or registered mail, with Colonial Bank, demanding a determination of
the fair market value of the shares. A stockholder who fails to file such
petition within 60 days of the Effective Date will be deemed to have accepted
the terms offered under the Merger. (At any time within such 60 days, any
stockholder will have the right to withdraw his demand for appraisal and accept
the terms of the Merger.) Within such 60 day period, such stockholder must also
submit to Trust Company Bank, BancGroup's transfer agent, his or her
certificates representing Bank Common Stock with a notation thereon that
appraisal rights have been requested. ANY STOCKHOLDER WHO FAILS TO SUBMIT HIS OR
HER STOCK CERTIFICATES FOR SUCH NOTATION WILL NO LONGER BE ENTITLED TO APPRAISAL
RIGHTS AND WILL BE DEEMED TO HAVE ACCEPTED THE TERMS OF THE MERGER. The OTS
shall determine the fair market value of such shares as of the date of the
Merger, exclusive of any
 
                                       23
<PAGE>   29
 
element of value arising from the accomplishment or expectation of the Merger.
Colonial Bank shall pay to such stockholders the fair market value as determined
by the OTS.
 
     The costs and expenses of any proceeding under this regulation may be
apportioned and assessed by the OTS as it deems equitable against all or some of
the parties. In making this determination the OTS shall consider whether any
party has acted arbitrarily, vexatiously, or not in good faith in respect to the
rights provided by this section.
 
     Cash, if any, received by a Bank stockholder who dissents to the Merger
will be taxable as having been received as a distribution in redemption of the
stockholder's shares of Bank Common Stock, subject to the provisions and
limitations of the Code. See "Certain Federal Income Tax Consequences."
 
     STOCKHOLDERS OF THE BANK WHO EXERCISE APPRAISAL RIGHTS MAY RECEIVE MORE OR
LESS CONSIDERATION THAN THOSE WHO DO NOT, IF THEIR SHARES ARE APPRAISED FOR MORE
OR LESS THAN THE AGGREGATE CONSIDERATION THEY WOULD HAVE RECEIVED PURSUANT TO
THE MERGER. THE FAILURE OF A HOLDER OF BANK COMMON STOCK TO VOTE AGAINST THE
MERGER WILL NOT ITSELF CONSTITUTE A WAIVER OF THE RIGHT TO RECEIVE PAYMENT FOR
HIS SHARES, NOR WILL A VOTE AGAINST THE MERGER SATISFY THE NOTICE REQUIREMENTS
REFERRED TO ABOVE. A STOCKHOLDER WHO HAS DEMANDED APPRAISAL RIGHTS SHALL
THEREAFTER NEITHER BE ENTITLED TO VOTE SUCH STOCK NOR BE ENTITLED TO THE PAYMENT
OF DIVIDENDS.
 
     If a stockholder does not hold shares directly or of record but instead
holds shares of Bank Common Stock through a bank, broker or other nominee, such
stockholder must act promptly to cause the bank, broker or other nominee, as the
record holder, to follow the steps outlined above properly and in a timely
manner to perfect such stockholder's dissenters' rights. Stockholders who hold
shares of Bank Common Stock through banks, brokers or other nominees are urged
to consult with such banks, brokers or nominees regarding these procedures.
 
     Stockholders who wish to exercise dissenters' rights should consult a legal
advisor before attempting to exercise such rights.
 
     References herein to applicable regulations are summaries of portions
thereof, do not purport to be complete, and are qualified in their entirety by
reference to applicable law. OTS regulation 12 C.F.R. sec. 552.14, is attached
hereto as Appendix B.
 
RESALE OF BANCGROUP COMMON STOCK
 
     The issuance of the shares of BancGroup Common Stock pursuant to the Merger
has been registered under the Securities Act of 1933 (the "Securities Act") and
the shares so issued may be traded without restriction, except that such
registration does not cover resales by persons ("Affiliates") receiving such
Common Stock who may be deemed to control or be controlled by, or be under
common control with the Bank at the time of the Special Meeting. Rule 145
promulgated by the Commission under the Securities Act restricts the resale of
Common Stock received in the Merger by Affiliates.
 
     The Bank will provide BancGroup with such information as may be reasonably
necessary to determine the identity of those persons (primarily officers,
directors and principal stockholders) who may be deemed to be Affiliates. The
Bank 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 Common Stock by such
person except pursuant to Rule 145 of the Commission or pursuant to an effective
registration 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 certificates 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 stop transfer orders will be given to BancGroup's stock transfer
agent.
 
ACCOUNTING TREATMENT
 
     The acquisition of the Bank 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
 
                                       24
<PAGE>   30
 
Effective Date of the Merger. Intangibles, in the approximate amount of
$1,574,000, will be amortized by charges or credits to future earnings over a
period of approximately twenty years.
 
                    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. The Class A
Common Stock had more limited voting rights than the 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
the Nasdaq National Market on February 24, 1995.
 
     The following table shows the dividends paid per share and indicates the
high and low closing prices for the Class A Common Stock as reported by on the
Nasdaq National Market up to February 24, 1995, and the same information

     On November 20, 1995, 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 $29 per share.
 
     At December 31, 1995, BancGroup's banking subsidiaries accounted for
approximately 98% of BancGroup's consolidated assets. BancGroup derives
substantially all of its income from dividends received from its subsidiary
banks. Various statutory provisions 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.
 
THE BANK
 
     There is no organized public market for the Bank's Common Stock. To the
knowledge of the Bank, 10,518 shares of Bank Common Stock have been transferred
since January 1, 1994. The Bank has no knowledge of the sales price, if any, in
such transfers.
 
     The Bank has paid one cash dividend. That dividend was paid in 1994 at the
rate of 15c per share. The Agreement contains certain restrictions on the Bank's
right to pay dividends prior to consummation of the Merger. See "APPROVAL OF THE
MERGER -- Conduct of Business Pending the Merger."

                     BANCGROUP CAPITAL STOCK AND DEBENTURES
 
     BancGroup's authorized capital stock consists of 44,000,000 shares of its
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 January 31, 1996, there were issued and
outstanding a total of 13,491,691 shares of 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 $9,416,000 are currently
outstanding and are convertible at any time into 345,321 shares of Common Stock,
subject to adjustment. There are 214,957 shares of Common Stock subject to
exercise under BancGroup's stock option plans. In addition to BancGroup Common
Stock issued in the Merger, BancGroup will issue additional shares of its Common
Stock in two pending acquisitions. See "BUSINESS OF BANCGROUP -- Proposed
Affiliate Banks."
 
     The following statements with respect to Common Stock and Preference Stock
are brief summaries of material provisions of Delaware law and 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.
 
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 Common Stock are entitled to share ratably in such dividends.
 
     Voting Rights.  Each holder of Common Stock has one vote for each share
held on matters presented for consideration by the stockholders.
 
     Preemptive Rights.  The holders of Common Stock have no preemptive rights
to acquire any additional shares of BancGroup.
 
     Issuance of Stock.  The BancGroup Certificate authorizes the BancGroup
Board to issue authorized shares of 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 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 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 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.

<PAGE>   32
 
1986 DEBENTURES
 
     BancGroup issued in 1986 its 7 1/2% Convertible Subordinated Debentures due
2011 in the total principal amount of $28,750,000 of which $9,416,000 are
outstanding at January 31, 1996. The 1986 Debentures were issued under a trust
indenture (the "1986 Indenture") between BancGroup and Trust Company 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 $28 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 345,321 shares of such 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 September 30, 1995, BancGroup's Senior Indebtedness as defined in the
1986 Indenture aggregated approximately $543.8 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 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.
 
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 BancGroup Board's power 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
"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 18 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
 
                                       27
<PAGE>   33
 
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 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 chairman and president of BancGroup, or 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. The current Board of Directors of
BancGroup owns approximately 15% of the outstanding shares of Common Stock of
BancGroup.
 
     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 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 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
 
                                       28
<PAGE>   34
 
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 Board has been
given 60 days' prior written notice of such proposed acquisition and within that
time period the Federal Reserve Board 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 Board issues written
notice of its intent not to disapprove the action. Under a rebuttable
presumption established by the Federal Reserve Board, 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, all stockholders of the Bank, other than
those properly exercising dissenters' rights of appraisal or receiving all cash
pursuant to an Election Form, will become holders of BancGroup Common Stock. The
rights of the holders of the Common Stock of the Bank who become holders of the
Common Stock of BancGroup 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 holders of Bank Common Stock
with the rights of the holders of the Common Stock of BancGroup. 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 the Bank's Stock Charter and bylaws, the Delaware
General Corporation Law (the "Delaware GCL") and the regulations of the OTS.
 
DIRECTOR ELECTIONS
 
     The Bank.  The Bank's directors are elected to terms of three years with
approximately one-third of the board to be elected annually. Stockholders of the
Bank have cumulative voting rights in the election of directors, which means a
stockholder is entitled to the number of votes as shall equal the number of
directors to be elected multiplied by the number of shares held by such
stockholder. The stockholder may give one candidate all of such votes or may
distribute votes among the directors to be elected as such stockholder
determines.
 
     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
 
     The Bank.  At a meeting of stockholders called expressly for such purpose,
stockholders of the Bank may remove a director with cause upon the affirmative
vote of the holders of at least a majority of the Common Stock entitled to vote.
 
     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.
 
                                       29
<PAGE>   35
 
VOTING
 
     The Bank.  Each share of Common Stock of the Bank is entitled to one vote
per share on all matters requiring a stockholder vote, except in the election of
directors, in which case stockholders have cumulative voting rights. See
"Director Elections."
 
     BancGroup.  Each stockholder is entitled to one vote for each share of
Common Stock held, and such holders are not entitled to cumulative voting rights
in the election of directors.
 
PREEMPTIVE RIGHTS
 
     The Bank.  Holders of the Bank's capital stock do not have preemptive
rights to acquire additional shares of capital stock which the Bank may issue.
 
     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
 
     The Bank.  Neither the Bank's Stock Charter nor bylaws contain any
provisions respecting the personal liability of directors.
 
     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
 
     The Bank.  Neither the Bank's Stock Charter nor bylaws contain any
provisions respecting indemnification of the Bank's directors.
 
     Pursuant to OTS regulations, the Bank shall indemnify any person against
whom an action is brought or threatened because that person is or was a
director, officer or employee of the Bank for any amount for which that person
becomes liable under a judgment and reasonable attorney's fees, actually paid or
incurred by that person in defending or settling such action, or in enforcing
his or her rights under such regulations if he or she obtains a favorable
judgment in such enforcement action. Indemnification shall be made to such
person only if:
 
          (1) Final judgment on the merits is in his or her favor; or
 
          (2) In case of:
 
           (i) Settlement,
 
             (ii) Final judgment against him or her, or
 
             (iii) Final judgment in his or her favor, other than on the merits,
        if a majority of the disinterested directors of the Bank determine that
        he or she was acting in good faith within the scope of his or her
        employment or authority as he or she could reasonably have perceived it
        under the circumstances and for a purpose he or she could reasonably
        have believed under the circumstances was in the best interests of the
        Bank or its members. However, no indemnification shall be made unless
        the Bank gives the OTS at least 60 days' notice of its intention to make
        such indemnification.
 
                                       30
<PAGE>   36
 
     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 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), such person must be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by such person in
connection therewith.
 
     In addition, BancGroup maintains an officers' and directors' insurance
policy and a separate indemnification agreement pursuant to which certain
officers and all directors of BancGroup would be entitled to indemnification
against certain liabilities, including reimbursement of certain expenses.
 
SPECIAL MEETINGS OF STOCKHOLDERS; ACTION WITHOUT A MEETING
 
     The Bank.  Special meetings of stockholders of the Bank may be called at
any time by the Chairman of the Board of the Bank, the President, or a majority
of the Board of Directors, and shall be called by the Chairman, the President or
Secretary upon the written request of the holders of at least 10 percent of the
outstanding shares of capital stock. Any action required to be taken at any
meeting of stockholders may be taken without a meeting if a consent, in writing,
setting forth the action to be taken, is given by all stockholders entitled to
vote on such matter.
 
     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
 
     The Bank.  Regulations of the OTS provide that mergers, consolidations and
sales of all or substantially all of the assets of the Bank must be approved by
the affirmative vote of at least two-thirds of the outstanding share of Bank
Common Stock. Stockholders of the Bank need not authorize a merger or other such
transaction if the Bank is the resulting corporation and if:
 
          (i) The Bank's Stock Charter is not changed;
 
          (ii) Each share of stock outstanding immediately prior to the
     effective date of the transaction is to be an identical outstanding share
     or a treasury share of the resulting Federal stock association after such
     effective date; and
 
        (iii) Either:
 
             (A) No shares of voting stock of the resulting Federal stock
        association and no securities convertible into such stock are to be
        issued, or delivered under the plan of combination, or
 
             (B) The authorized unissued shares of the treasury shares of voting
        stock of the resulting Federal stock association to be issued or
        delivered under the plan of combination, plus those initially issuable
        upon conversion of any securities to be issued or delivered under such
        plan, do not exceed 15% of the total shares of voting stock of such
        association outstanding immediately prior to the effective date of the
        combination.
 
                                       31
<PAGE>   37
 
     BancGroup.  The Delaware GCL provides that mergers and sales of
substantially all of the assets of a corporation must be approved by a majority
of the outstanding stock of the corporation entitled to vote thereon. The
Delaware GCL law 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.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION AND BYLAWS
 
     The Bank.  Amendments to the Bank's Stock Charter must be approved by the
affirmative vote of the holders of at least a majority of the outstanding shares
of Bank Common Stock, after recommendation by the Board of Directors. The Bank's
bylaws may be amended by a vote of at least two-thirds of the Board of Directors
or by at least a majority of the shares of Common Stock voted at a meeting of
stockholders.
 
     BancGroup.  Under the Delaware GCL, a 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 Director 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
 
     The Bank.  Stockholders of the Bank have the right to exercise dissenters'
rights of appraisal respecting mergers, consolidations and sales of all or
substantially all of the assets of the Bank. For a description of such rights,
see "APPROVAL OF THE MERGER -- Rights of Dissenting Stockholders." Stockholders
of a federal savings bank do not have such appraisal rights if the consideration
to be paid for the shares of the bank in the transaction constitutes only
"qualified consideration" and if the shares of the bank are listed on a national
securities exchange or quoted on the Nasdaq National Market. "Qualified
consideration" means cash, or shares listed on a national securities exchange or
quoted on the Nasdaq National Market, or a combination of both.
 
     BancGroup.  Under the Delaware GCL, a stockholder has the right, in certain
circumstances, to dissent from certain corporate transactions (such as a Merger
but not a sale of assets) and receive the fair value (excluding any appreciation
or depreciation as a consequence or in expectation of the transaction) of his
shares in cash in lieu of the consideration he otherwise would have received in
the transaction. 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, or held of record by more than 2,000 stockholders (as is
BancGroup Common Stock), and (ii) stockholders are permitted by the
 
                                       32
<PAGE>   38
 
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.
 
ANTITAKEOVER STATUTES
 
     The Bank.  Neither the OTS regulations nor Alabama law has a business
combination statute that may have antitakeover effects.
 
     BancGroup.  As a Delaware corporation, BancGroup is subject to the business
combination statute described under the heading "BANCGROUP CAPITAL STOCK AND
DEBENTURES -- Changes in Control -- Control Acquisitions."
 
PREFERRED STOCK
 
     The Bank.  The Bank's Stock Charter permits the Bank to issue up to
1,000,000 shares of preferred stock, par value $1.00 per share. The shares may
be issued from time to time on such terms as the Bank's Board of Directors may
determine. Among other things, the Board may decide the voting rights (including
the right of the preferred stock to vote as a class), dividend rights,
redemption, and liquidation preferences of the preferred stock to be issued.
 
     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."
 
OTHER PROVISIONS
 
     The Bank's Stock Charter provides that no shares of capital stock shall be
issued to officers, directors or controlling persons of the Bank other than as a
part of a general public offering unless the issue is approved by at least a
majority of the Bank's shares of Common Stock outstanding. BancGroup's
Certificate has no similar provisions.
 
EFFECT OF THE MERGER ON BANK STOCKHOLDERS
 
     As of January 31, 1996, the number of stockholders of record of the Bank
was 196 and the number of shares of Common Stock outstanding was 399,688. As of
that date, BancGroup had 13,491,691 shares of Common Stock outstanding with
5,388 stockholders of record.
 
     Assuming at the Effective Date a 10-day average market price per share of
the BancGroup Common Stock of $32, an aggregate amount of 81,250 shares of
BancGroup Common Stock would be distributed to the stockholders of the Bank
pursuant to the Merger. These shares would represent .60% of the total shares of
Common Stock outstanding after the Merger, not counting shares of BancGroup
Common Stock to be issued in other pending acquisitions.
 
     The issuance of the Common Stock pursuant to the Merger will reduce the
percentage interest of the Common Stock currently held by each principal
stockholder and each director and officer of BancGroup. Such reduction will not
be material. See "BUSINESS OF BANCGROUP -- Voting Securities and Principal
Stockholders."
 
     BancGroup has entered into agreements pursuant to which approximately
2,898,412 additional shares of BancGroup Common Stock will be issued. See
"BUSINESS OF BANCGROUP -- Proposed Affiliate Banks."

DOTHAN FEDERAL SAVINGS BANK UNAUDITED RESULTS OF OPERATIONS AND FINANCIAL
HIGHLIGHTS FOR THE SIX MONTHS ENDED DECEMBER 31, 1995
 
     Dothan Federal Savings Bank ("Dothan Federal") unaudited results for the
six months ended December 31, 1995 reported net income of $71,000 or $.18 per
share, versus $137,000 or $.34 per share for the prior year.
 
     For the second quarter of 1995, Dothan Federal showed net income of $40,000
or $.10 per share, as compared to net income of $70,000 or $.18 per share, for
the same period in 1994. The decrease in net income in the second quarter of
1995 as compared to the same period in 1994 is due to an increase in interest
expense as a result of increased deposit balances of approximately $7,691,000
over the same period in 1994.
 
     Net interest income for the six months ended December 31, 1995 decreased
over 1994, again as a result of increased interest expense from higher deposit
balances. Other income and other expense remained consistent from six months
ended 1994 to 1995.
 
     Set forth below are selected financial highlights for Dothan Federal for
the periods indicated:

COMMERCIAL BANCORP OF GEORGIA, INC. UNAUDITED RESULTS OF OPERATIONS AND
FINANCIAL HIGHLIGHTS FOR YEAR ENDED DECEMBER 31, 1995
 
     Commercial Bancorp of Georgia, Inc. ("CBG") unaudited results for the year
ended December 31, 1995 reported net income of $857,000 or $.47 per share,
versus $698,000 or $.38 per share for the prior year.
 
     For the fourth quarter of 1995, CBG experienced a loss of $852,000 or
($.47) per share, as compared to net income of $121,000 or $.07 per share, for
the same period in 1994. The fourth quarter loss reflected additional provision
for loan losses of $892,000 as a result of $380,000 in normal monthly provision
and a one-time increase of $512,000 due to estimated change in economic
uncertainty as compared to approximately $290,000 for the fourth quarter of
1994. There was also approximately $1,219,000 of proposed acquisition related
expenses incurred in the fourth quarter of 1995.
 
     Net interest income for the year ended December 31, 1995 increased over the
1994 as a result of increased interest income from slightly higher interest
rates and increased construction loan volume. Other income remained consistent
from year end 1994 to 1995.
 
     BancGroup has previously considered the impact of the aforementioned fourth
quarter additional expenses and earnings trends in evaluating the exchange ratio
in the Merger, therefore, BancGroup does not expect the decrease in earnings or
additional expenses to have a material impact on BancGroup's future earnings or
financial condition.
 
     BancGroup has advised CBG that CBG's unaudited 1995 financial results will
not affect the proposed Merger.
 
     Set forth below are selected financial highlights for CBG for the periods
indicated:

SOUTHERN BANKING CORPORATION UNAUDITED RESULTS OF OPERATIONS AND FINANCIAL
HIGHLIGHTS FOR YEAR ENDED DECEMBER 31, 1995
 
     Southern Banking Corporation ("SBC") unaudited results for the year ended
December 31, 1995 reported net income of $2,091,000 or $.57 per share, versus
$1,734,000 or $.63 per share for the prior year.
 
     For the fourth quarter of 1995, SBC recorded net income $122,000 or $.03
per share, as compared to net income of $726,000 or $.27 per share, for the same
period in 1994. The decrease in fourth quarter earnings in 1995 as compared to
the same period in 1994 was the result of approximately $893,000 in acquisition
related expenses incurred in the fourth quarter of 1995; as well as
approximately $250,000 in additional loan loss provision as a result of decline
in asset quality in the fourth quarter.
 
     Net interest income for the year ended December 31, 1995 increased over the
1994 as a result of increased interest income from slightly higher interest
rates and increased loan volume. Other income remained consistent from year end
1994 to 1995. Other expense increased from year end 1994 to 1995 as a result of
approximately $893,000 in acquisition related expenses incurred in 1995.
 
     BancGroup has previously considered the impact of the aforementioned fourth
quarter additional expenses and earnings trends in evaluating the exchange ratio
in the Merger, therefore, BancGroup does not expect the decrease in earnings or
additional expenses to have a material impact on BancGroup's future earnings or
financial condition.
 
     BancGroup has advised SBC that SBC's unaudited 1995 financial results will
not affect the proposed Merger.
 
     Set forth below are selected financial highlights for SBC for the periods
indicated:

                          DOTHAN FEDERAL SAVINGS BANK
 
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATION
 
  Comparison of the Three Months Ended September 30, 1995 and 1994
 
FINANCIAL CONDITION
 
     ASSETS.  Total assets increased $1,442,987 from $40,182,106 as of June 30,
1994 to $41,625,093 at September 30, 1994. The net increase was primarily due to
an increase in loans and investments of $842,213 and an increase in cash of
$370,444. Total assets increased $3,426,465 from $44,657,061 at June 30, 1995 to
$48,083,526 at September 30, 1995. The increase was due to an increase in loans
and investments of $1,649,329 and a decrease in cash federal funds of
$1,729,797.
 
     LIABILITIES.  Total liabilities were $38,002,015 at September 30, 1994, an
increase of $1,473,229 from June 30, 1994, and were $44,129,704 at September 30,
1995, a $3,370,553 increase from June 30, 1995. Both the 1994 and 1995 increases
were due to increases of deposits and borrowed money of $1,507,010 and
$3,248,635, respectively.
 
     CAPITAL.  Capital as of September 30, 1994 totaled $3,623,078, a $30,242
decrease from capital of $3,653,320 at June 30, 1994. The net decrease consists
of net income of $66,683 less cash dividends declared of $59,953, and a $36,972
adjustment in unrealized losses on securities. Capital as of September 30, 1995
totaled $3,953,822, a $55,912 increase from capital of $3,897,910 at June 30,
1995. The net increase consists of net income of $30,449 and a $25,463
adjustment in unrealized gains on securities.
 
RESULTS OF OPERATIONS
 
     SUMMARY.  The Bank's net income decreased $36,234 from $66,683 or $.17 per
share to $30,449 or $.08 per share for the three months ended September 30, 1994
and 1995, respectively. The decrease can be attributed to a $69,247 decrease in
net interest income.
 
     NET INTEREST INCOME.  Net interest income decreased from $363,154 for the
three months ended September 30, 1994, to $293,907 for the same period of 1995.
Interest earning assets increased $905,994 to $39,542,116 in the three months
ended September 30, 1994 and increased $2,964,580 to $45,599,405 during the same
period in 1995. Interest bearing liabilities increased $1,507,010 to $37,531,827
in the three months ended September 30, 1994 and increased $3,248,635 to
$43,542,314 during the same period in 1995.
 
     PROVISION FOR LOAN LOSSES.  During the first three months ended September
30, 1994 and 1995, the Bank added $15,000 to the allowance for loan losses. Even
though the Bank's asset quality continues to be strong, the Bank's management
and Board of Directors feels that a monthly increase of $5,000 would help to
strengthen the Bank's allowance due to higher risk commercial loans being
portfolioed in 1995.
 
     NON-INTEREST INCOME.  For the three months ended September 30, 1995, the
Bank's non-interest income increased $12,693 to $29,820 compared to the same
period in 1994. The increase is primarily due to a $10,000 payment received to
resolve a legal matter.
 
     NON-INTEREST EXPENSE.  Non-interest expense decreased $995 to $254,340 for
the first three months of 1995 from $255,335 for the same period in 1994. The
decrease is primarily due to a $9,602 decrease in compensation expense offset by
a $10,128 increase in consulting fees.
 
     PROVISION FOR INCOME TAXES.  The provision for income taxes for the three
months ended September 30, 1995 and 1994 was $23,938 and $43,263, respectively.
The income tax expense expressed as percent of income before income taxes was
44.01% for 1995 and 39.35% for 1994.

                          DOTHAN FEDERAL SAVINGS BANK
 
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
     The following discussion and financial information is presented to aid the
understanding of the current financial position and results of operations of
Dothan Federal Savings Bank, Dothan, Alabama (the "Bank") and should be read in
conjunction with the Financial Statements and Notes. With respect to the figures
for the years ended June 30, 1995 and 1994 and for the three month periods ended
September 30, 1995 and 1994, which are unaudited, in the opinion of management
all adjustments (none of which were other than normal recurring adjustments)
necessary for a fair statement of such results for such periods have been
included. The Bank has one banking facility located in Houston County, Alabama.
 
  As of and For the Years Ended June 30, 1995 and 1994
 
FINANCIAL CONDITION
 
     ASSETS.  The total assets of the Bank were $44,657,061 at June 30, 1995, a
$4,474,955 increase from the 1994 year end assets of $40,182,106. At June 30,
1995, earning assets totaled $42,606,060 or 95.41% of total assets, compared to
$38,554,768, or 95.95% at June 30, 1994.
 
     The Bank's investment securities portfolio decreased from $8,221,091 at
June 30, 1994 to $6,778,919 at year end 1995. The primary reason for the
decrease was normal principal repayments and maturities.
 
     During 1995, the average yield on interest bearing deposits in other banks
increased from an average rate of 3.47% in 1994 to an average of 5.91%. The
balance of interest bearing deposits in other banks decreased from $417,151 at
June 30, 1994 to $369,732 at June 30, 1995. The decrease was due mainly to the
purchase of adjustable rate mortgage loans to help improve the Bank's interest
rate risk.
 
     Total loans, net of unearned income, increased by $5,584,292 during 1995,
or 18.53% from the June 30, 1994 total of $30,128,839. Mortgage loans increased
$4,118,242 or 15.31%. Commercial non-real estate loans decreased by $716,620 or
26.97%. Consumer loans increased $944,252 or 34.05%. The increase in loan demand
was caused by an increase in rates during the first quarter, which caused
consumers to enter the market early in the year and take advantage of lower
rates while they could.
 
     An allowance is established for uncollectible interest on loans that are 60
days past due based on management's periodic evaluations. The allowance is
established by a charge to interest income equal to all interest previously
accrued, and income is subsequently recognized to the extent that cash payments
are received until, in management's judgment, the borrower's ability to make
periodic interest and principal payments has been demonstrated, in which case
the loan is returned to accrual status. Loans that had been placed on nonaccrual
status at June 30, 1995 and 1994 totaled $145,531 and $10,452, respectively.
 
     The Allowance for loan losses is maintained through provisions charged to
expense at levels which management considers adequate to absorb losses inherent
in the loan portfolio. The allowance is decreased by charge-offs, net of
recoveries. Management's evaluation of the allowance includes a review of all
loans for which full collectibility is not reasonably assured and considers,
among other factors, prior years' loss experience, economic conditions,
distribution of loans by risk class, and the estimated value of underlying
collateral. Though management believes the allowance for loan losses to be
adequate, the ultimate losses may vary from these evaluations; however, the
allowance is reviewed periodically and, as adjustments become necessary, they
are reported in earnings in the periods in which they become known.
 
     The Bank's allowance for loan losses at June 30, 1995 and 1994, was
$255,722 and $212,313, respectively, with the corresponding ratios of allowance
to total loans being .72% and .71%. Net charge-offs totaled $16,591 and $25,023
in 1995 and 1994, respectively, representing .05% and .08% of net loans.

     DEPOSITS.  The Bank relies on deposits to fund loans and other investments.
Total deposits at June 30, 1995 were $37,627,012, an increase of $5,435,528 or
16.88% from June 30, 1994. Demand and time deposit accounts at June 30, 1995
were $2,837,515 and $28,852,755, respectively, representing a decrease of
$68,154 and an increase of $6,503,415, respectively. Savings and money market
accounts totaled $5,936,742 at June 30, 1995, representing a decrease of
$999,733. The decrease in savings and money market accounts and increase in time
deposits was due to customers withdrawing their funds from the low yielding
savings accounts and depositing them in higher yielding time deposits.
 
     LIQUIDITY.  Liquidity refers to the ability of the Bank to meet borrowing
needs and withdrawal demands of its customers, while also providing funds for
operating expenses and its own cash flow requirements. The Bank achieves its
desired liquidity from management of both assets and liabilities. 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 or sales of
other earning assets. In addition, liquidity is continuously provided through
the acquisition of new deposits or the rollover of matured deposits.
 
     The Bank normally meets it short-term liquidity requirements with interest
bearing deposits in other banks and short term government securities; however,
occasionally it may become necessary to borrow from the Federal Home Loan Bank
to meet short-term cash flow needs. At June 30, 1995, the Bank's average
regulatory liquidity ratio was 8.65% which is 3.65% above the OTS's Requirement
of 5.00%.
 
     The Bank's liquid assets as of June 30, 1995 totaled $2,526,392, down from
$3,415,856 on June 30, 1994. Management considers the Bank's liquidity sources
to be adequate to meet its current and projected needs.
 
     The Bank's total outstanding advances from the FHLB of Atlanta were
$2,666,667 as of June 30, 1995 compared to $3,833,333 on June 30, 1994. This
decrease of $1,166,666 was due to the repayment of maturing advances with funds
received from increased deposits.
 
     CAPITAL.  Capital is a measure of the Bank's financial soundness and
viability. The Bank is committed to maintaining a strong capital position to
protect shareholders and depositors, provide for reasonable growth, and fully
comply with all regulatory requirements while paying dividends to its
shareholders.
 
     The Bank's capital at June 30, 1995 totaled $3,897,910 compared to
$3,653,320 in 1994. This growth in the Bank's capital has been through the
retention of internally generated earnings. Total capital as expressed as a
percent of total assets as of June 30, 1995 and 1994 was 8.73% and 9.09%,
respectively.
 
     As a federally chartered savings bank, the Bank is required by its primary
regulator, the Office of Thrift Supervision ("OTS"), to maintain capital
sufficient to meet three requirements, as defined: (1) a tangible capital
requirement equal to 1.5% of adjusted total assets; (2) a leverage or core
capital requirement of 3% of adjusted total assets, though it is anticipated
that most institutions will be required by the regulators to maintain capital of
an additional 100 to 200 basis points; and (3) a risk-based capital requirement
equal to 8% of risk-weighted assets, which were approximately $21,895,200 at
June 30, 1995. Assets and off-balance sheet commitments are assigned a
credit-risk weighting based upon their relative risk ranging from 0% for assets
backed by the full faith and credit of the United States Government or that pose
no credit risk to the Bank, to the 100% for assets such as commercial loans,
delinquent, or repossessed assets.

(a) The required minimum based on 5% would be $2,233,155 leaving an excess of
    $1,670,791.
 
     Capital requirements continue to be under study by the OTS. Management
continues to monitor these requirements and contemplated changes and believes
that the Bank will continue to exceed its regulatory minimum requirements.
 
     The Bank has not been required by the OTS to incorporate an interest rate
risk component to the risk-based capital requirement. This regulation requires a
deduction from risk-based capital based on an institution's exposure to interest
rate risk. Management believes the Bank would continue to exceed its regulatory
minimum requirements if the interest rate risk component is ever required.
 
RESULTS OF OPERATIONS
 
     For the year ended June 30, 1995 the Bank recorded net income of $217,207
which represents a 54.47% decrease from 1994 net income of $477,048 and a 65.83%
decrease from 1993 net income at $635,747. Earnings per share were $0.54, $1.19
and $1.59, respectively, for the years ended June 30, 1995, 1994 and 1993.
 
     NET INTEREST INCOME.  By the nature of its business, the largest portion of
the Bank's income is derived primarily from net interest income. Net interest
income is the difference between interest income, earned primarily on loans and
investment securities, and interest expense, which is paid on deposits and other
interest-bearing liabilities. Many factors influence net interest income,
including fluctuations in interest rates and changes in the volume and mix of
earning assets and interest-bearing liabilities.
 
     The table included in this section details the distribution of average
assets, liabilities and shareholders' equity, with the interest rate
differentials for the Bank for the two years ended June 30, 1995 and 1993.
 
     Interest income for 1995 of $3,293,441 represents a 4.23% increase over
1994 interest income of $3,159,905. The increase in income occurred as a result
of an increase in the volume of earning assets of $4,051,292 from 1994 to 1995.
 
     Interest income on loans represents the largest source of revenue for the
Bank. Interest income on loans increased from $2,797,004 in 1994 to $2,873,845
in 1995. This $76,841 or 2.75% increase was due to an increase in net loans of
$5,540,883 even though the average yield on loans decreased from 9.05% to 8.37%
during the year.
 
     Even though investment securities decreased by $1,442,172 in 1995 interest
income on investment securities increased by $52,068 in 1995 over 1994. This
increase occurred due to the maturing of lower yielding securities and the
repricing of adjustable mortgage backed securities to a higher rate.
 
                                       57
<PAGE>   63
 
     Interest income on interest bearing deposits in other banks in 1995
increased from $32,248 in 1994 to $36,875. This increase was due to the increase
in the yield on these deposits in 1995 to 5.91% compared to 3.47% during 1994.
 
     Interest expense is the Bank's largest single expense category. In 1995,
interest expense totaled $1,874,878, a 28.45% increase from the 1994 interest
expense of $1,459,562. This increase was due to the increased volume of deposits
and FHLB borrowings, and slightly higher rates.
 
     The resulting net interest income for 1995 was $1,418,563, a 16.57%
decrease from the 1994 net interest income of $1,700,343. This decrease was due
to interest bearing liabilities repricing at a faster rate than interest earning
assets. This timing difference would lead to lower earnings in a time of
increasing interest rates.
 
     PROVISION FOR LOAN LOSSES.  The provision for loan losses in 1995 and 1994
was $60,000. The purpose of the provision for loan losses is to replace
reductions in the allowance for loan losses caused by actual charge-offs and to
establish adequate reserves for the growth of the loan portfolio. The allowance
for loan losses represents the estimated uncollectible amount of loans included
in the Bank's loan portfolio, and is available to absorb potential losses from
any category of loans.
 
     NON-INTEREST INCOME.  Non-interest income is generated by various financial
services and activities. As pressures on net interest income continue, expansion
of these services and the related fee income is of great importance to the
future profitability of the Bank. Among these fees are deposit service charge,
safe deposit box rent, and net gains on the sale of assets.
 
     Total non-interest income decreased $13,039 in 1995 to $58,214. This was
primarily due to decreased gains on the sale of mortgage loans during the year.
 
     NON-INTEREST EXPENSE.  Total non-interest expense for 1995 totaled
$1,056,644 compared to $956,423 for the previous year, an increase of $100,221
or 10.48%. The majority of the increase was due to the implementation of a
profit sharing plan for the Bank's employees. Payments under the plan amounted
to $18,954 during 1995.
 
     INCOME TAX EXPENSE.  Income before taxes for 1995 was $360,133, a 52.31%
decrease from the 1994 income before taxes of $755,173. The income tax expense
expressed as a percent of income before taxes was 39.69% and 36.83% for 1995 and
1994, respectively. The income tax expense for 1995 totaled $142,926 compared to
$278,125 for 1994. The Bank did not begin recording a provision for income taxes
until July, 1993 due to the utilization of net operating loss carry forwards.
The provision for income taxes includes deferred taxes on temporary differences
between income tax and financial accounting.
 
NEW ACCOUNTING STANDARDS
 
     On June 30, 1994, the Bank adopted Financial Accounting Standards Board
("FASB") Statement of Financial Accounting Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities." The Bank has
elected to classify all its mortgage-backed securities and mortgage related
securities as available-for-sale and all its U.S. Government securities as
held-to-maturity. The effect of this election decreased stockholder's equity by
$40,525 and $127,861 as of June 30, 1995 and 1994, respectively.
 
IMPACT OF INFLATION AND INTEREST RATE SENSITIVITY
 
     The financial statements and related data presented herein have been
prepared in accordance with generally accepted accounting principles which
require the measurement of financial position and operating results without
considering changes in the relative purchasing power of money over time due to
inflation.
 
     The majority of assets and liabilities of a financial institution are
monetary in nature and therefore differ greatly from most commercial and
industrial companies that have an important impact on the growth of total assets
and creates the need to generate more equity capital in order to maintain an
appropriate equity to assets ratio. Another significant effect of inflation is
on non-interest expenses, which tend to rise during periods of inflation.

     A portion of the Bank's interest earning assets are long-term fixed rate
mortgage loans and mortgage-backed securities, while its principal source of
funds are saving deposits with maturities of three years or less. Because of the
short-term nature of the savings deposits, their costs generally reflect returns
currently available in the market. Accordingly, the savings deposits have a high
degree of interest rate sensitivity while the mortgage loan portfolio, to the
extent of fixed rate loans, is relatively fixed and has much less sensitivity to
changes in current market rates. Although these conditions are somewhat
mitigated by the Bank's risk management strategies of selling long-term fixed
rate loans and reinvesting in adjustable-rate mortgage-backed securities and
loans, changes in market interest rates tend to directly affect the level of net
interest income.

Atlanta area. This bank located in Georgia is sometimes referred to as Colonial
Bank -- Georgia. Colonial Mortgage Company, a subsidiary of Colonial Bank, is a
mortgage banking company with approximately $9 billion in residential loan
serving and 13 offices in 12 states. BancGroup's commercial banking loan
portfolio is comprised primarily of commercial real estate loans (26%) 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. The
lending activities of Colonial Bank in Alabama are dependent upon the demands
within the local markets of its branches. Based on this demand, loans
collateralized by commercial and residential real estate have been the fastest
growing component of Colonial Bank's loan portfolio.
 
LENDING ACTIVITIES
 
     BancGroup, through the branches and offices of its subsidiary banks, makes
loans for a range of business and personal uses in response to local demands for
credit. Loans are concentrated in Alabama, Georgia and Tennessee and are
dependent upon economic conditions in those states. Alabama has historically
been a slow growth state. The following broad categories of loans have varying
risks and underwriting standards.
 
     - Real Estate -- Commercial.  Loans classified as commercial real estate
      loans are loans which are collateralized by real estate and substantially
      dependent upon cash flow from income-producing improvements attached to
      the real estate. For BancGroup, these primarily consist of apartments,
      hotels, office buildings, shopping centers, amusement/recreational
      facilities, one to four family residential housing developments, and
      health service facilities.
 
      Loans within this category are underwritten based on projected cash flows
      and loan-to-appraised-value ratios of 80% or less. The risks associated
      with commercial real estate loans are primarily dependent upon real estate
      values in local market areas, the equity investments of borrowers, and the
      borrowers' experience and expertise. BancGroup has diversified its
      portfolio of commercial real estate loans with less than 10% of its total
      loan portfolio concentrated in any of the above-mentioned industries.
 
     - Real Estate Construction.  Construction loans include loans to finance
      single family and multifamily residential as well as nonresidential real
      estate. Loan values for these loans are from 80% to 85% of completed
      appraised values. The principal risks associated with these loans are
      related to the borrowers' ability to complete the project and local market
      demand, the sales market, presales or preleasing, and permanent loan
      commitments. BancGroup evaluates presale requirements, preleasing rates,
      permanent loan take-out commitments, as well as other factors in
      underwriting construction loans.
 
     - Real Estate-Residential.  These loans consist of loans made to finance
      one to four family residences and home equity loans on residences.
      BancGroup may loan up to 95% of appraised value on these loans without
      other collateral or security. The principal risks associated with one to
      four family residential loans are the borrowers' debt coverage ratios and
      real estate values.
 
     - Commercial, Financial, and Agricultural.  Loans classified as commercial,
      financial, and agricultural consist of secured and unsecured credit lines
      and equipment loans for various industrial, agricultural, commercial,
      retail, or service businesses.
 
                                       61
<PAGE>   67
 
      The risk associated with loans in this category are generally related to
      the earnings capacity and cash flows generated from the individual
      business activities of the borrowers. Collateral consists primarily of
      business equipment, inventory, and accounts receivables with loan-to-value
      ratios of less than 80%. Credit may be extended on an unsecured basis or
      in excess of 80% of collateral value in circumstances as described in the
      paragraph below.
 
     - Installment and Consumer.  Installment and consumer loans are loans to
      individuals for various purposes. Automobile loans and unsecured loans
      make up the majority of these loans. The principal source of repayment is
      the earnings capacity of the individual borrowers as well as the value of
      the collateral. Installment and consumer loans are sometimes made on an
      unsecured basis or with loan-to-value ratios in excess of 80%.
 
     Collateral values referenced above are monitored by loan officers through
property inspections, reference to broad measures of market values, as well as
current experience with similar properties or collateral. Loans with
loan-to-value ratios in excess of 80% have potentially higher risks which are
offset by other factors including the borrower's or guarantors' credit
worthiness, the borrower's other banking relationships, the bank's lending
experience with the borrower, and any other potential sources of repayment.
 
     BancGroup's subsidiary banks fund loans primarily with customer deposits
approximately 10% of which are considered more rate sensitive or volatile than
other deposits. In addition the subsidiary banks borrow funds from the Federal
Home Loan Bank to fund residential real estate loans.

MANAGEMENT INFORMATION
 
     Certain information regarding the biographies of the directors and
executive officers of BancGroup, executive compensation and related party
transactions is included in BancGroup's Annual Report on Form 10-K for the
fiscal year ending December 31, 1994, at items 10, 11, and 13 and is
incorporated herein by reference.
 
CERTAIN REGULATORY CONSIDERATIONS
 
     BancGroup is a registered bank holding company subject to supervision and
regulation by the Federal Reserve. As such, it is subject to the Bank Holding
Company Act of 1956 as amended (the "BHC Act") and many of the Federal Reserve's
regulations promulgated thereunder. It is also subject to regulation by the
Georgia Department of Banking and Finance and by the OTS as a savings and loan
holding company.
 
     BancGroup's subsidiary banks, Colonial Bank, Colonial Bank of Tennessee and
Colonial Bank -- Georgia, (the "Subsidiary Banks"), are subject to supervision
and examination by applicable federal and state banking agencies. Colonial Bank,
as a state chartered bank and not a member of the Federal Reserve system, is
regulated and examined both by the State of Alabama Banking Department and by
the FDIC. Colonial Bank of Tennessee is also state chartered and not a member of
the Federal Reserve system and is regulated by both the State of Tennessee
Department of Financial Institutions and by the FDIC. Colonial Bank -- Georgia,
is a federal savings bank and is regulated by the OTS. The deposits of the
Subsidiary Banks are insured by the FDIC to the extent provided by law. The FDIC
assesses deposit insurance premiums the amount of which may, in the future,
depend in part on the condition of the Subsidiary Banks. Moreover, the FDIC may
terminate deposit insurance of the Subsidiary Banks under certain circumstances.
Both the FDIC and the respective state regulatory authorities have jurisdiction
over a number of the same matters, including lending decisions, branching and
mergers.
 
     One limitation under the BHC Act and the Federal Reserve's regulations
requires that BancGroup obtain prior approval of the Federal Reserve before
BancGroup acquires, directly or indirectly, more than five percent of any class
of voting securities of another bank. Prior approval also must be obtained
before BancGroup acquires all or substantially all of the assets of another
bank, or before it merges or consolidates with another bank holding company.
BancGroup may not engage in "non-banking" activities unless it demonstrates to
the Federal Reserve's satisfaction that the activity in question is closely
related to banking and a proper incident thereto. Because BancGroup is a
registered bank holding company, persons seeking to acquire 25 percent or more
of any class of its voting securities must receive the approval of the Federal
Reserve. Similarly, under certain circumstances, persons seeking to acquire
between 10 percent and 25 percent also may be required to obtain prior Federal
Reserve approval.
 
     In 1989 Congress expressly authorized the acquisition of savings
associations by bank holding companies. BancGroup must obtain the prior approval
of the Federal Reserve and the OTS (among other agencies) before making such an
acquisition, and must demonstrate that the likely benefits to the public of the
proposed transaction (such as greater convenience, increased competition, or
gains in efficiency) outweigh potential burdens (such as an undue concentration
of resources, decreased or unfair competition, conflicts of interest, or unsound
banking practices).
 
     Following enactment in 1991 of the FDIC Improvement Act, banks now are
subject to increased reporting requirements and more frequent examinations by
the bank regulators. The agencies also now have the authority to dictate certain
key decisions that formerly were left to management, including compensation
standards, loan underwriting standards, asset growth, and payment of dividends.
Failure to comply with these new standards, or failure to maintain capital above
specified levels set by the regulators, could lead to the imposition of
penalties or the forced resignation of management. If a bank becomes critically
undercapitalized, the bank agencies have the authority to place an institution
into receivership or require that the bank be sold to, or merged with, another
financial institution.
 
     In September 1994 Congress enacted the Riegle-Neal Interstate Banking and
Branching Efficiency Act of 1994. This legislation, among other things, amended
the BHC Act to permit bank holding companies,
 
                                       65
<PAGE>   71
 
subject to certain limitations, to acquire either control or substantial assets
of a bank located in states other than that bank holding company's home state
regardless of state law prohibitions. This legislation became effective on
September 29, 1995. In addition, this legislation also amended the Federal
Deposit Insurance Act to permit, beginning on June 1, 1997 (or earlier where
state legislatures provide express authorization), the merger of insured banks
with banks in other states.
 
     The officers and directors of BancGroup and the Subsidiary Banks are
subject to numerous insider transactions restrictions, including limits on the
amount and terms of transactions involving the Subsidiary Banks, on the one
hand, and their principal stockholders, officers, directors, and affiliates on
the other. There are a number of other laws that govern the relationship between
the Subsidiary Banks and their customers. For instance, the Community
Reinvestment Act is designed to encourage lending by banks to persons in low and
moderate income areas. The Home Mortgage Disclosure Act and the Equal Credit
Opportunity Act attempt to minimize lending decisions based on impermissible
criteria, such as race or gender. The Truth-in-Lending Act and the
Truth-in-Savings Act require banks to provide full disclosure of relevant terms
related to loans and savings accounts, respectively. Anti-tying restrictions
(which prohibit, for instance, conditioning the availability or terms of credit
on the purchase of another banking product) further restrict the Subsidiary
Banks' relationships with their customers.
 
     The Budget Reconciliation Act of 1995 ("Budget Act") was passed by Congress
but subsequently vetoed by President Clinton. Congressional leadership and
President Clinton began discussions in 1995 to determine whether the Congress
and the Administration could reach a compromise on budget reconciliation. It is
unknown whether these negotiations will be successful. The Budget Act originally
passed by Congress and subsequently vetoed by the President contained a
provision which directed the FDIC to set a one-time special assessment on
SAIF-insured deposits which would be in an amount sufficient to recapitalize the
Savings Association Insurance Fund ("SAIF"). It is anticipated that a special
assessment in the range of $0.80 to $0.90 per $100 of SAIF-insured deposits
would be necessary in order to recapitalize the SAIF, if the assessment were to
be made in the next six months. In the event a budget reconciliation agreement
is reached between the Congress and the Administration, it is expected that the
agreement would include the special assessment provision contained in the
original Budget Act. If no agreement is reached by the Congress and the
Administration, it is still possible that Congress could attach such a provision
to another piece of legislation or pass such a provision as a free-standing
bill. The Administration, in testimony before Congress and in the press, has
indicated its support of the recapitalization of SAIF in the manner provided in
the Budget Act.
 
     BancGroup's subsidiary banks maintain deposits which are insured by both
the SAIF and the BIF (Bank Insurance Fund). The SAIF insured deposits in all of
BancGroup's subsidiary bank's total $797 million. Under the Budget Act certain
of these deposits would be excluded from the special assessment. The total
special assessment that would be due under the Budget Act is estimated to be
approximately $5.4 million.
 
     It should be noted that supervision, regulation, and examination of
BancGroup and the Subsidiary Banks are intended primarily for the protection of
depositors, not stockholders.

                              BUSINESS OF THE BANK
 
GENERAL
 
     The Bank was organized in July, 1988. On July 22, 1988, the Bank commenced
its business operations as a federally chartered stock savings bank. The Bank is
a member of the Federal Home Loan Bank System and its deposits are insured by
the SAIF.
 
     The Bank's primary business is to accept savings deposits from the general
public and to make real estate loans secured by residential and commercial
property, and to a lesser extent, to make commercial and consumer loans. Its
income is derived from interest and fees in connection with such loans. The
Bank's principal expenses are interest paid on deposits and operating expenses.
 
     The Bank conducts its operations through one office located at 1962 West
Main Street, Dothan, Alabama. The Bank's primary market area is the City of
Dothan and Houston County in the southeastern portion of the State of Alabama.

                         ADJOURNMENT OF SPECIAL MEETING
 
     Approval of the Merger by the Bank's stockholders requires the affirmative
vote of at least two-thirds of the total votes eligible to be cast at the
Special Meeting. In the event there are an insufficient number of shares of Bank
Common Stock represented in person or by proxy at the Special Meeting to approve
the Merger, the Bank's Board of Directors in its discretion may adjourn the
Special Meeting to a later date. The place and date to which the Special Meeting
would be adjourned would be announced at the Special Meeting, but would not be
more than 30 days after the date of the Special Meeting. Proxies voted against
the Merger will not be voted to adjourn the Special Meeting.
 
     The effect of any such adjournment would be to permit the Bank to solicit
additional proxies for approval of the Merger. While such an adjournment would
not invalidate any proxies previously filed, including those filed by
stockholders voting against the Merger, it would afford the Bank the opportunity
to solicit additional proxies in favor of the Merger.

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 the Bank.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
Dothan Federal Savings Bank:
 
     We have audited the accompanying statements of financial condition of
DOTHAN FEDERAL SAVINGS BANK (a federally chartered savings bank) as of June 30,
1995 and 1994 and the related statements of income, stockholders' equity, and
cash flows for each of the three years in the period ended June 30, 1995. These
financial statements are the responsibility of the Bank's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Dothan Federal Savings Bank
as of June 30, 1995 and 1994 and the results of its operations and its cash
flows for each of the three years in the period ended June 30, 1995 in
conformity with generally accepted accounting principles.
 
     As discussed in Note 1 to the financial statements, effective June 30,
1994, the Bank changed its method of accounting for investment securities and
mortgage-backed securities.

                         NOTES TO FINANCIAL STATEMENTS
                             JUNE 30, 1995 AND 1994
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
SECURITIES
 
     Securities designated as available for sale are reported at fair value. The
unrealized difference between amortized cost and fair value on securities
available for sale is excluded from earnings and is reported net of deferred
taxes as a component of stockholders' equity. This caption includes securities
that management intends to use as part of its asset/liability management
strategy or that may be sold in response to changes in interest rates, changes
in prepayment risk, liquidity needs, or for other purposes.
 
     Securities designated as held to maturity are reported at amortized cost,
as the Bank has both the ability and positive intent to hold these securities to
maturity. There are no securities classified as trading as of June 30, 1995 or
1994.
 
     Amortization of premium and accretion of discount are computed under the
interest method. The adjusted cost of the specific security sold is used to
compute realized gain or loss on the sale of securities.
 
     On June 30, 1994, Dothan Federal Savings Bank (the "Bank") adopted
Financial Accounting Standards Board ("FASB") Statement of Financial Accounting
Standards ("SFAS") No. 115, "Accounting for Certain Investments in Debt and
Equity Securities."
 
     Initial adoption of SFAS No. 115 was accomplished by transferring certain
securities previously shown as investment securities or mortgage-backed
securities to the available for sale portfolio and had the effect of decreasing
stockholders' equity by $127,861 at June 30, 1994; it had no effect on 1994
income.
 
     Prior to the adoption of SFAS No. 115, securities determined to be held on
a long-term basis or until maturity were accounted for in a manner similar to
securities held to maturity.
 
LOANS RECEIVABLE
 
     Loans receivable are stated at unpaid principal balances, less the
allowance for loan losses and net of deferred loan origination fees and
premiums.
 
     An allowance is established for uncollectible interest on loans that are 60
days past due based on management's periodic evaluations. The allowance is
established by a charge to interest income equal to all interest previously
accrued, and income is subsequently recognized only to the extent that cash
payments are received until, in management's judgment, the borrower's ability to
make periodic interest and principal payments has been demonstrated, in which
case the loan is returned to accrual status.
 
ALLOWANCE FOR LOAN LOSSES
 
     The allowance for loan losses is maintained through provisions charged to
expense at levels which management considers adequate to absorb losses inherent
in the loan portfolio. The allowance is decreased by charge-offs, net of
recoveries. Management's evaluation of the allowance includes a review of all
loans for which full collectibility is not reasonably assured and considers,
among other factors, prior years' loss experience, economic conditions,
distribution of loans by risk class, and the estimated value of underlying
collateral. Though management believes the allowance for loan losses to be
adequate, ultimate losses may vary from these evaluations; however, the
allowance is reviewed periodically and, as adjustments become necessary, they
are reported in earnings in the periods in which they become known.
 
     During 1993, the FASB issued SFAS No. 114, "Accounting by Creditors for
Impairment of a Loan," which is effective for fiscal years beginning after
December 15, 1994. SFAS No. 114 requires that impaired loans be valued based on
the present value of those loans' estimated cash flows at each loan's effective
interest rate or the loan's observable market price or the fair value of the
underlying collateral. In October 1994, the

FASB issued SFAS No. 118, "Accounting by Creditors for Impairment of a
Loan -- Income Recognition and Disclosures", an amendment to SFAS No. 114. SFAS
No. 118 amends SFAS No. 114 to allow a creditor to use existing methods for
recognizing interest on an impaired loan. Management adopted SFAS Nos. 114 and
118 as of July 1, 1995; however, given the Bank's current loan portfolio
composition, the impact of adoption was not material.
 
LOAN ORIGINATION FEES, PREMIUMS, AND DISCOUNTS
 
     Loan origination fees, net of direct costs associated with originating or
acquiring loans, are treated as an adjustment to the yield of the related loans
using the interest method over the contractual term of the loans. Such
adjustments are reflected in "Interest and fees on loans" in the accompanying
statements of income. Loan commitment fees are recognized into income upon
expiration of the commitment period, unless the commitment results in the loan
being funded and maintained in the loan portfolio.
 
     Premiums paid and discounts received in connection with loans receivable
are amortized to interest income over the lives of the loans using the interest
method.
 
LAND, BUILDINGS, AND EQUIPMENT
 
     Land, buildings, and equipment are carried at cost, net of accumulated
depreciation. Depreciation is computed on the straight-line method over the
estimated useful lives of the assets (40 years for buildings and 3 to 25 years
for equipment).
 
INTANGIBLE ASSETS
 
     Intangible assets, included in "Other Assets" in the accompanying
statements of financial condition, consist of premiums paid to acquire the
deposits of other financial institutions. These costs ($33,498 and $50,562 at
June 30, 1995 and 1994, respectively) are being amortized using an accelerated
method over an eight year period which approximates the expected deposit
relationship lives. Amortization expense totaled $17,064, $20,565, and $24,065
in fiscal 1995, 1994, and 1993, respectively.
 
INCOME TAXES
 
     The financial statements have been prepared on an accrual basis. Because
some income and expense items are recognized in different periods for financial
reporting purposes and for purposes of computing currently payable income taxes,
a provision or credit for deferred income taxes is made for such temporary
differences.
 
     Effective July 1, 1991, the Bank adopted the asset and liability approach
for financial accounting and reporting of income taxes pursuant to SFAS No. 109,
"Accounting for Income Taxes."
 
     No provision for income taxes was reflected in the statement of income for
the year ended June 30, 1993 due to the utilization of net operating loss
("NOL") carryforwards. The Bank utilized all of its federal and state NOL
carryforwards during fiscal 1994.
 
CHANGE IN PAR VALUE
 
     On October 22, 1992, the Bank changed the par value of all authorized
preferred and common stock from $1.00 per share to $.01 per share.

FINANCIAL STATEMENT RECLASSIFICATION
 
     The financial statements for the prior years have been reclassified in
certain instances in order to conform with the 1995 financial statement
presentation. The reclassification did not change total assets or net income in
the prior years.
 
PENDING ACCOUNTING STANDARDS
 
  Financial Instruments
 
     In December 1991, the FASB issued SFAS No. 107, "Disclosures about Fair
Values of Financial Instruments", adoption of which is required for fiscal years
ending after December 15, 1995. In October 1994, the FASB issued SFAS No. 119,
"Disclosure about Derivative Financial Instruments and Fair Value of Financial
Instruments," adoption of which is required for fiscal years ending after
December 15, 1995. The Bank has elected not to adopt the provisions of these
statements before the required date.
 
DISCLOSURE OF CERTAIN RISKS
 
     In December 1994, the Accounting Standards Division of the AICPA approved
SOP 94-6, "Disclosure of Certain Significant Risks and Uncertainties." SOP 94-6
requires disclosures in the financial statements beyond those now being required
or generally made in the financial statements about the risks and uncertainties
existing as of the date of those financial statements in the following areas:
nature of operations, use of estimates in the preparation of financial
statements, certain significant estimates, and current vulnerability due to
certain concentrations. SOP 94-6 is effective for financial statements issued
for fiscal years ending after December 15, 1995. The Bank has elected not to
adopt the provisions of SOP 94-6 before the required date.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
ACCOUNTING FOR IMPAIRMENT OF LONG-LIVED ASSETS
 
     In March 1995, the FASB issued SFAS No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." SFAS No. 121
establishes accounting standards for evaluating the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used and for long-lived assets and certain identifiable
intangibles to be disposed of. The Bank has elected not to adopt the provisions
of SFAS No. 121 until the required date, though management does not believe that
the adoption of SFAS No. 121 will have a significant impact on the Bank's
financial position or on the results of its operations.
 
MORTGAGE SERVICING RIGHTS
 
In May 1995, the FASB issued SFAS No. 122, "Accounting for Mortgage Servicing
Rights," an amendment to SFAS No. 65. SFAS No. 122 amends certain provisions of
SFAS No. 65 to eliminate the accounting distinction between rights to service
mortgage loans for others that are acquired through loan origination activities
and those acquired through purchase transactions. Management does not intend to
adopt the provisions of SFAS No. 122 before the required date. Based on the
Bank's current operating activities, management does not believe that the
adoption of this Statement will have a material impact on the Bank's financial
condition or results of operations.

     As a savings bank, the Bank has a credit concentration in residential
mortgage loans. The majority of the Bank's customers are located in Dothan,
Alabama, and the surrounding area. The ability of these borrowers to repay is
highly dependent on local economic conditions.
 
     Loans receivable at June 30, 1995 and 1994 included $145,531 and $10,452,
respectively, in loans that had been placed on nonaccrual status. Interest
income recognized on the nonaccrual loans outstanding at June 30, 1995 and 1994
was $2,217 and $1,119, respectively, as compared to $11,184 and $1,340 of
interest income in 1995 and 1994, respectively, that would have been recorded
under the original terms of the loans.
 
     At June 30, 1995 and 1994, loans to key officers, directors and principal

5. REAL ESTATE OWNED
 
     Real estate owned consists either of properties acquired through
foreclosure and held pending sale or properties sold under mortgage loans to
facilitate sale and accounted for under the deposit method. Real estate owned is
carried at the lower of loan balance or fair value, less estimated costs of
disposition. Subsequent to foreclosure, real estate owned is evaluated on an
individual basis for changes in fair value. Future declines in fair value of the
asset less costs of disposition below its carrying amount result in an increase
in the valuation allowance account. Future increases in fair value of the asset
less costs of disposition above its carrying amount reduce the valuation
allowance account, but not below zero. Minor costs relating to holding and
maintaining the property are expensed and amounts incurred to improve the
property are capitalized. The amounts expensed in fiscal 1995, 1994, and 1993
were $2,142, $4,280, and $10,699, respectively. The amount capitalized in fiscal
1995 was $1,020. No amounts were capitalized in fiscal 1994 or 1993. Valuations
are periodically performed by management and a provision for estimated losses on
real estate is charged to earnings when such losses are anticipated. No property
was held pending sale at June 30, 1995. Property held pending sale at June 30,
1994 consisted of residential property with a basis of $27,000 and no valuation
allowance.
 
     There were no valuation allowances for real estate owned for the years
ended June 30, 1995 and 1994 and there was no related activity in the valuation
allowances.

10. COMMITMENTS AND CONTINGENCIES
 
FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
 
     The Bank is party to financial instruments with off-balance sheet risk in
the normal course of business, primarily to meet the financing needs of its
customers. These financial instruments consisted of commitments to extend credit
and amounted to $182,000 at June 30, 1995. The Bank's policies as to collateral
and assumption of credit risk for off-balance sheet items are essentially the
same as those for extension of credit to its customers.
 
LITIGATION
 
     The Bank is a 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 financial statements.
 
FDIC ASSESSMENTS
 
     The FDIC-SAIF assessments became effective January 1, 1990. The FDIC
assessment rate was 20.8 basis points of insured deposits through December 31,
1990, and has been 23 basis points since January 1, 1991. However, significant
debate has ensued in Congress and within the industry as to the disparity
between bank and thrift deposit insurance premiums which arose during 1995 when
bank premiums were reduced when the target capitalization of the Bank Insurance
Fund ("BIF") was achieved. To eliminate and reduce the disparity and provide for
the recapitalization of the Savings Association Insurance Fund ("SAIF"), a
special recapitalization premium for SAIF deposits has been discussed
approximating 85 basis points. No decision has been finalized as to the
resolution of BIF/SAIF premium disparity or the fund recapitalization issue. In
the event of an 85 basis point assessment, the Bank would incur approximately
$320,000 in expense.
 
11. COMPENSATION AND BENEFITS
 
     During fiscal 1994, the Bank adopted a profit sharing plan and distributes
funds earned to employees on a semiannual basis. Total distributions during 1995
related to this plan were $18,954, which are included in "Salaries and employee
benefits" in the accompanying statements of income. The Bank also adopted a
defined-contribution 401(k) plan, but does not contribute or match the
employees' contributions.
 
     In December 1990 and November 1992, the FASB issued SFAS No. 106,
"Accounting for Postretirement Benefits Other Than Pensions" and SFAS No. 112,
"Employers' Accounting for Postemployment Benefits", respectively. The Bank does
not offer these benefits, as defined, to its employees and, accordingly,

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
SFAS No. 106 had no effect on the Bank's 1995 financial statements and SFAS No.
112 at the date of adoption will have no effect on the Bank's financial
condition based on current activity.
 
12. REGULATION
 
     As a federally chartered savings bank, the Bank is required by its primary
regulator, the Office of Thrift Supervision ("OTS"), to maintain capital
sufficient to meet three requirements, as defined: (1) a tangible capital
requirement equal to 1.5% of adjusted total assets; (2) a leverage or core
capital requirement of 3% of adjusted total assets, though it is anticipated
that most institutions will be required by the regulators to maintain capital of
an additional 100 to 200 basis points; and (3) a risk-based capital requirement
equal to 8% of risk-weighted assets, which were approximately $21,895,200 at
June 30, 1995. Assets and off-balance sheet commitments are assigned a
credit-risk weighting based upon their relative risk ranging from 0% for assets
backed by the full faith and credit of the United States Government or that pose
no credit risk to the Bank, to 100% for assets such as commercial loans,
delinquent, or repossessed assets.
 
     The following is a reconciliation of the Bank's total stockholders' equity
to the Bank's tangible, core, and risk-based capital available to meet its
regulatory requirements:

                          DOTHAN FEDERAL SAVINGS BANK
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Bank has not been required by the OTS to incorporate an interest rate
risk component to the risk-based capital requirement. This regulation requires a
deduction from risk-based capital based on an institution's exposure to interest
rate risk. Management believes the Bank would continue to exceed its regulatory
minimum requirements if the interest rate risk component is ever required.
 
     Effective December 19, 1992, the Bank became subject to additional capital
standards established by the Federal Deposit Insurance Corporation Improvement
Act of 1991 ("FDICIA"). These regulations established capital standards in five
categories ranging from "critically undercapitalized" to "well capitalized," and
defined "well capitalized" as at least 5% for core (leverage) capital and at
least 10% for risk-based capital. Institutions with a core capital less than 4%
or risk-based capital less than 8% are considered "undercapitalized," and
subject to increasingly stringent prompt corrective action measures. The Bank's
capital ratios above place it in the "well capitalized" category.
 
13. INTEREST RATE SENSITIVITY
 
     A portion of the Bank's interest earning assets are long-term fixed rate
mortgage loans and mortgage-backed securities (approximately 79%), while its
principal source of funds are savings deposits with maturities of three years or
less (approximately 99%). Because of the short-term nature of the savings
deposits, their cost generally reflects returns currently available in the
market. Accordingly, the savings deposits have a high degree of interest rate
sensitivity while the mortgage loan portfolio, to the extent of fixed rate
loans, is relatively fixed and has much less sensitivity to changes in current
market rates. Although these conditions are somewhat mitigated by the Bank's
risk management strategies of selling long-term fixed rate loans and reinvesting
in adjustable-rate mortgage-backed securities, changes in market interest rates
tend to directly affect the level of net interest income.
 
14. SUBSEQUENT EVENT
 
     On January 22, 1996, the Bank entered into a definitive agreement for the
acquisition of the Bank by The Colonial BancGroup, Inc. ("BancGroup"), in which
BancGroup will acquire all of the outstanding stock of the Bank, consideration
consisting of both shares of BancGroup's common stock and cash for an aggregate
purchase price of approximately $5,200,000. This transaction is subject to,
among other things, approval by the stockholders of the Bank and BancGroup and
approval by the appropriate regulatory authorities. In connection with the
pending acquisition, the Bank has entered into agreements with its president and
chief executive officer and its vice president and controller pursuant to which
each could receive cash payments following the merger, should they terminate
employment with the Bank or BancGroup following the merger. Total payments
possible under the agreements, if exercised, would approximate $54,000.

                          DOTHAN FEDERAL SAVINGS BANK
 
                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                          SEPTEMBER 30, 1995 AND 1994
 
1. BASIS OF PRESENTATION
 
     The condensed financial statements were prepared by Dothan Federal Savings
Bank (the "Bank") without audit, but in the opinion of management, reflect all
adjustments necessary for the fair presentation of the Bank's financial position
and results of operations for the three month periods ended September 30, 1995
and 1994. Results of operations for the interim 1995 period are not necessarily
indicative of results expected for the full year. While certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted, the Bank believes that the disclosures herein are adequate to make the
information presented not misleading. These condensed financial statements
should be read in conjunction with the financial statements and the notes
thereto included in the Bank's statements of financial condition for the year
ended June 30, 1995. The accounting policies employed are the same as those
shown in Note 1 to the statements of financial condition.
 
2. IMPLEMENTATION OF STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NOS. 114 AND
   118
 
     During 1993, the FASB issued SFAS No. 114, "Accounting by Creditors for
Impairment of a Loan," which is effective for fiscal years beginning after
December 15, 1994. SFAS No. 114 requires that impaired loans be valued based on
the present value of those loans' estimated cash flows at each loan's effective
interest rate or the loan's observable market price or the fair value of the
underlying collateral. In October 1994, the FASB issued SFAS No. 118,
"Accounting by Creditors for Impairment of a Loan-Income Recognition and
Disclosures", an amendment to SFAS No. 114. SFAS No. 118 amends SFAS No. 114 to
allow a creditor to use existing methods for recognizing interest on an impaired
loan. Management adopted SFAS Nos. 114 and 118 as of July 1, 1995; however,
given the Bank's current loan portfolio composition, the impact of adoption was
not material.
 
3. FDIC ASSESSMENTS
 
     The FDIC-SAIF assessments became effective January 1, 1990. The FDIC
assessment rate was 20.8 basis points of insured deposits through December 31,
1990, and has been 23 basis points since January 1, 1991. However, significant
debate has ensued in Congress and within the industry as to the disparity
between bank and thrift deposit insurance premiums which arose during 1995 when
bank premiums were reduced when the target capitalization of the Bank Insurance
Fund ("BIF") was achieved. To eliminate or reduce the disparity and provide for
the recapitalization of the Savings Association Insurance Fund ("SAIF"), a
special recapitalization premium for SAIF deposits has been discussed
approximating 85 basis points. No decision has been finalized as to the
resolution of BIF/SAIF premium disparity or the fund recapitalization issue. In
the event of an 85 basis point assessment, the Bank would incur approximately
$320,000 in expense.
 
4. SUBSEQUENT EVENT
 
     On January 22, 1996, the Bank entered into a definitive agreement for the
acquisition of the Bank by the Colonial BancGroup, Inc. ("BancGroup"), in which
BancGroup will acquire all of the outstanding stock of the Bank, consideration
consisting of both shares of BancGroup's common stock and cash for an aggregate
purchase price approximating $5,200,000. This transaction is subject to, among
other things, approval by the stockholders of the Bank and BancGroup and
approval by the appropriate regulatory authorities. In connection with the
pending acquisition, the Bank has entered into agreements with its president and
chief executive officer and its vice president and controller, pursuant to which
each could receive cash payments following the merger should they terminate
employment with the Bank or BancGroup following the merger. Total payments
possible under the agreements, if exercised, would approximate $54,000.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Commercial Bancorp of Georgia, Inc.
  and Subsidiaries
Lawrenceville, Georgia
 
     We have audited the accompanying consolidated balance sheet of Commercial
Bancorp of Georgia, Inc. (formerly known as Commercial Bancorp of Gwinnett,
Inc.) and Subsidiaries as of December 31, 1994, and the related consolidated
statements of income, changes in stockholders' equity, and cash flows for the
year then ended. These consolidated financial statements are the responsibility
of Commercial Bancorp of Georgia, Inc.'s management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audit. We audited the consolidated financial statements of Commercial Bancorp of
Georgia, Inc. (formerly known as Commercial Bancorp of Gwinnett, Inc.) and
Subsidiary as of December 31, 1994 and 1993, and for the three years then ended,
and our reports dated January 19, 1995, except for the information presented in
Note L for which the date is March 2, 1995, and January 25, 1994, expressed an
unqualified opinion on those statements. We audited the consolidated financial
statements of the former Commercial Bancorp of Georgia, Inc. and Subsidiary as
of December 31, 1994, and for the year then ended, and our report dated March
10, 1995, expressed an unqualified opinion on those statements. The consolidated
financial statements of the former Commercial Bancorp of Georgia, Inc. and
Subsidiary as of December 31, 1993, and for the two years then ended, were
audited by other auditors whose report, dated March 2, 1994, expressed an
unqualified opinion on those statements.
 
     The consolidated financial statements of Commercial Bancorp of Georgia,
Inc. (formerly known as Commercial Bancorp of Gwinnett, Inc.) as of December 31,
1994 and 1993, and for the three years then ended have been restated to reflect
the 1995 pooling of interests with the former Commercial Bancorp of Georgia,
Inc., as described in Note B of the consolidated financial statements.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the restated 1994 consolidated financial statements
referred to above present fairly, in all material respects, the consolidated
financial position of Commercial Bancorp of Georgia, Inc. (formerly known as
Commercial Bancorp of Gwinnett, Inc.) and Subsidiaries as of December 31, 1994,
and the results of their operations and their cash flows for the year then ended
in conformity with generally accepted accounting principles. We previously
audited and reported on the consolidated balance sheet of Commercial Bancorp of
Georgia, Inc. (formerly known as Commercial Bancorp of Gwinnett, Inc.) as of
December 31, 1993, and the related consolidated statements of income and cash
flows for the two years then ended, prior to their restatement for the 1995
pooling of interests. Its contribution to total assets, revenues, and net income
represented 33%, 30% and 59% of the respective restated totals. Separate
consolidated financial statements of the former Commercial Bancorp of Georgia,
Inc. included in the 1993 restated consolidated balance sheet and consolidated
statements of income and cash flows for the two years then ended were audited
and reported on separately by other auditors. We also audited the combination of
the accompanying consolidated balance sheets and consolidated statements of
income and cash flows as of and for the two years ended December 31, 1993, after
restatement for the 1995 pooling of interests. In our opinion, such consolidated
statements have been properly combined on the basis described in Note A of the
notes to the consolidated financial statements.
 
     As discussed in Note A to the consolidated financial statements, the
Company changed its method of accounting for investment securities in 1994 to
adopt the provisions of Statement of Financial Accounting Standards No. 115.

              COMMERCIAL BANCORP OF GEORGIA, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 1994, 1993 AND 1992
 
NOTE A.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies of Commercial Bancorp of Georgia,
Inc. and subsidiaries conform to generally accepted accounting principles and to
general practices within the banking industry. The following is a summary of the
more significant of these policies.
 
     The financial statements have been prepared in conformity with generally
accepted accounting principles. In preparing the financial statements,
management is required to make estimates and assumptions that affect the
reported amounts of assets and liabilities as of the date of the balance sheet
and revenues and expenses for the period. Actual results could differ
significantly from those estimates. Material estimates that are particularly
susceptible to significant change in the near term relate, for example, to the
determination of the allowance for loan losses, the market valuation reserve on
investment securities available for sale, and the valuation of other real estate
acquired in connection with foreclosures or in satisfaction of loans. Management
believes that the allowance for loan losses is adequate, the decline in market
value of investment securities available for sale is temporary, and the
valuation of other real estate is appropriate. While management uses available
information to recognize losses on loans, future additions to the allowance may
be necessary based on changes in economic conditions. In addition, various
regulatory agencies, as an integral part of their examination process,
periodically review the allowance for loan losses and valuation of other real
estate. Such agencies may require the recognition of additions to the allowance
or valuation adjustments to other real estate based on their judgments about
information available to them at the time of their examination.
 
BASIS OF PRESENTATION
 
     The consolidated financial statements of Commercial Bancorp of Georgia,
Inc. (formerly Commercial Bancorp of Gwinnett, Inc.) (Parent Company) and its
wholly-owned subsidiary, Commercial Bank of Gwinnett, collectively known as the
Company as of December 31, 1994 and 1993, and for the three years then ended
have been restated to reflect the 1995 pooling of interests with the former
Commercial Bancorp of Georgia, Inc. and Subsidiary as described in Note B. These
consolidated financial statements include the accounts of both entities and
their wholly-owned subsidiaries, Commercial Bank of Gwinnett and Commercial Bank
of Georgia, collectively know as the Company. The stock of the Parent Company
held by the former Commercial Bancorp of Georgia, Inc. has been treated as
treasury stock. All other significant intercompany accounts and transactions
have been eliminated in consolidation.
 
INVESTMENT SECURITIES
 
     In 1992, Georgia segregated its investment securities portfolio into
securities held to maturity and those available for sale. Investments in debt
securities, for which management has both the ability and intent to hold to
maturity, are carried at amortized cost. Investments in debt securities which
management believes may be sold prior to maturity, in connection with changes in
interest rates, prepayment risk, changes in the Company's liquidity or other
similar factors, are classified in 1993 and 1992 as available for sale and are
carried at the lower of aggregate cost or market. All Gwinnett investment
securities in 1993 and 1992 are classified as held to maturity.
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 115 (SFAS 115) on the accounting and reporting for
investments in all debt securities and equity securities that have readily
determinable fair values. SFAS 115 requires that investments are to be
classified as held to maturity, available for sale or trading securities. Held
to maturity securities are to be reported at amortized cost, while available for
sale and trading securities are to be reported at fair value. The Company has
adopted SFAS 115 in 1994 as required.

              COMMERCIAL BANCORP OF GEORGIA, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In 1994, investment securities held to maturity are reported at amortized
cost. Investment securities available for sale are reported at fair value, with
unrealized gains and losses reported as a separate component of stockholders'
equity, net of the related tax effect. Other investments are reported at cost.
Earnings are reported when interest is accrued or when dividends are received.
 
     Premium and discount on all investment securities are amortized (deducted)
and accreted (added), respectively, to interest income on the effective yield
method over the period to the maturity of the related securities. Premium and
discount on mortgage-backed securities are amortized (deducted) and accreted
(added), respectively, to interest income using a method which approximates a
level yield over the period to maturity of the related securities taking into
consideration assumed prepayment patterns.
 
     Gains or losses on disposition are computed by the specific identification
method for all securities.
 
LOANS
 
     Loans are reported at the gross amount outstanding less net deferred loan
fees and a valuation allowance for loan losses. Interest income on all loans is
recognized over the terms of the loans based on the unpaid daily principal
amount outstanding. If the collectibility of interest appears doubtful, the
accrual thereof is discontinued. Loan origination fees, net of direct loan
origination costs, are deferred and recognized as income over the life of the
related loan on a level-yield basis.
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 114 (SFAS 114) on accounting by creditors for
impairment of a loan. SFAS 114, as amended by SFAS 118, requires that impaired
loans be measured based on the present value of expected future cash flows
discounted at the loan's effective interest rate, or at the loan's fair value if
the loan is collateral dependent. The provisions of SFAS 114 are effective for
the Company beginning in 1995. The adoption is not expected to have a
significant adverse effect on the Company.
 
     Loans held for sale represent loans originated for sale by the Company in
the secondary market and are reported at the lower of cost or market.
 
     Gains and losses on sales of loans and participating interests in loans are
recognized at the time of sale, as determined by the difference between the net
sales proceeds and the fair value of the loans sold. Discounts recorded to
adjust the value of the portions of the loans retained to fair value are
amortized to income over the life of the loan.
 
ALLOWANCE FOR LOAN LOSSES
 
     The allowance for loan losses is established through a provision for loan
losses charged to expense. The allowance represents an amount which, in
management's judgment, will be adequate to absorb probable losses on existing
loans that may become uncollectible. Management's judgment in determining the
adequacy of the allowance is based on evaluations of the collectibility of loans
and takes into consideration such factors as changes in the nature and volume of
the loan portfolio, current economic conditions that may affect the borrower's
ability to pay, overall portfolio quality and review of specific problem loans.
Periodic revisions are made to the allowance when circumstances which
necessitate such revisions become known. Recognized losses are charged to the
allowance for loan losses, while subsequent recoveries are added to the
allowance.
 
PREMISES AND EQUIPMENT
 
     Premises and equipment are reported at cost less accumulated depreciation
and amortization. For financial reporting purposes, depreciation and
amortization are computed using primarily straight-line methods over the
estimated useful lives of the assets. Capital lease assets are amortized over
the shorter of the estimated useful lives of the assets or term of the related
leases. Expenditures for maintenance and repairs are
 
                                      F-29

              COMMERCIAL BANCORP OF GEORGIA, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
charged to operations as incurred, while major renewals and betterments are
capitalized. When property is disposed of, the related cost and accumulated
depreciation are removed from the accounts and any gain or loss is reflected in
income. For Federal tax reporting purposes, depreciation and amortization are
computed using primarily accelerated methods.
 
OTHER REAL ESTATE
 
     Other real estate represents property acquired through foreclosure or in
settlement of loans and is recorded at the lower of cost or fair value less
estimated selling expenses and a valuation allowance for losses. The allowance
represents an amount which, in management's judgement, will be adequate to
absorb probable losses. Losses incurred in the acquisition of foreclosed
properties are charged against the allowance for loan losses at the time of
foreclosure. Provisions for subsequent devaluation of other real estate are
charged against the current period's operations. Losses on disposal of other
real estate are charged to the valuation allowance for losses. Costs associated
with improving the property are capitalized to the extent fair value less
estimated selling expenses is not exceeded. Holding costs for other real estate
are expensed as incurred.
 
ORGANIZATIONAL COSTS
 
     The expenses associated with the formation of the Company were capitalized
as organizational costs and are being amortized on the straight-line method over
five years.
 
INTANGIBLE ASSETS
 
     Intangible assets, primarily arising from premiums paid in acquiring
deposits of other financial institutions, are amortized on a straight-line basis
over a period of 120 months. Certain legal and other costs incurred in
connection with the acquisition of branch facilities and related deposits from
other financial institutions have been capitalized and are amortized using the
straight-line method over 60 months.
 
INCOME TAXES
 
     The tax effect of transactions is recorded at current tax rates in the
periods the transactions are reported for financial statement purposes. Deferred
income taxes are established for the temporary differences between the financial
reporting basis and the tax basis of the Company's assets and liabilities at
enacted tax rates expected to be in effect when such amounts are realized or
settled. The Company files its income tax returns on a consolidated basis.
 
PENDING ACCOUNTING PRONOUNCEMENTS
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 107 (SFAS 107) which requires disclosure of current
market value information related to certain assets and liabilities, both on- and
off-balance sheet, and Statement of Financial Accounting Standards No. 119 (SFAS
119) which requires disclosures about derivative financial instruments. These
pronouncements are not effective for the Company until 1995. The adoption of
SFAS 107 and SFAS 119 is not expected to have a significant adverse effect on
the Company.
 
EARNINGS PER SHARE
 
     Earnings per share is based on the weighted average number of shares
outstanding during the period (1,826,711 in 1994, 1993 and 1992). Stock options
and warrants, as described in Note K, are considered to be common stock
equivalents for purposes of calculating earnings per share. The effect of
including these common stock equivalents in the earnings per share calculation
for 1994, 1993 and 1992 is anti-dilutive.

CASH AND CASH EQUIVALENTS
 
     For purposes of reporting cash flows, cash and cash equivalents include
cash on hand, amounts due from banks and federal funds sold. Generally, federal
funds are purchased and sold for one-day periods.
 
RECLASSIFICATIONS
 
     Certain reclassifications have been made in the 1993 and 1992 financial
statements to conform with the 1994 presentation.
 
NOTE B.  BUSINESS COMBINATION AND RESTATEMENT OF FINANCIAL STATEMENTS
 
     On March 2, 1995, the former Commercial Bancorp of Georgia, Inc. merged
with Commercial Bancorp of Gwinnett, Inc., and Commercial Bancorp of Gwinnett,
Inc., the surviving entity, changed its name to Commercial Bancorp of Georgia,
Inc. On September 30, 1995, Commercial Bank of Georgia merged with Commercial
Bank of Gwinnett, and Commercial Bank of Gwinnett, the surviving entity, changed
its name to Commercial Bank of Georgia. A total of 1,236,711 shares of
Commercial Bancorp of Gwinnett, Inc. stock was issued for all of the issued and
outstanding shares of the former Commercial Bancorp of Georgia, Inc. No cash,
except for nominal dissenting shareholders and fractional shares, was paid in
the transaction.
 
     The transaction was accounted for as a pooling of interests. The financial
statements for all periods presented have been restated to include the financial
position and results of operations of the former Commercial Bancorp of Georgia,
Inc.
 
     The Company's consolidated financial data have been restated as follows:

investment securities totaling $2,553,851 to available for sale. The unrealized
loss on available for sale securities, net of the related deferred taxes of
$78,315, is $152,026 at December 31, 1994, and is included as a separate
component of stockholders' equity.
 
     The Government agency securities classified as held to maturity at December
31, 1994, with a market value of approximately $7,191,000, consist of Federal
Home Loan Bank and Federal National Mortgage Association securities.
Approximately $3,196,000 of these securities are derivative securities. These
securities have maturities which range from 1996 through 1999 and have a current
weighted-average net yield of 5.84%. The market value of these securities is
generally affected positively by declining interest rates and negatively by
increasing interest rates. In addition, the market value increases or decreases
based on supply and/or demand for a particular type of security and various
other factors. Presently, the market value of these securities is volatile due
to the above interest and market factors.
 
     The carrying value and estimated market value of investment securities held
to maturity and the amortized cost and estimated market value of investment
securities available for sale at December 31, 1994, by contractual maturity, are
shown below. Expected maturities will differ from contractual maturities because
borrowers may have the right to call or prepay obligations without call or
prepayment penalties. Mortgage-backed securities have been allocated based on
stated maturity dates after considering assumed prepayment patterns.

prevailing at the time for comparable transactions with other borrowers.
 
     As of December 31, 1994, the Company had a $50,000 short-term unsecured
note payable to a related party. The note is scheduled to mature in May 1995 and

(10.5% at December 31, 1994). There were no such borrowings in 1993.

     In connection with the Company's formation and initial stock offering,
255,000 non-transferable warrants were issued to organizing stockholders and
certain officers. The warrants allow such individuals to purchase one additional
share of common stock for each share purchased in connection with the initial
offering and are exercisable for ten years from the date that Gwinnett commenced
operations (July 27, 1990) at the greater of the Company's book value per common
share as of the most recent quarter-end or $10 per share. At December 31, 1994
and 1993, all issued warrants were outstanding.
 
     The Company's current employment contract with the President and CEO of the
Company provides for the right to receive cash payments based upon the
appreciation in the value of the Company's common stock over time (Stock
Appreciation Rights). This executive has been granted the right to receive a
total of 13,565 units of Stock Appreciation Rights over three years beginning in
1990. The value of the units depends on the Bank's performance, as defined in
the employment agreement, and the units are exercisable for a period of seven
years after the date of grant. At December 31, 1994, all 13,565 units have been
granted and none have been exercised.
 
     Georgia banking laws limit the amount of dividends which the Banks may pay
to the Parent Company without obtaining prior approval from the Georgia
Department of Banking and Finance. Such approval would be required if either (a)
the Bank's ratio of equity capital to adjusted total assets is less than 6%; (b)
the aggregate amount of dividends declared by the Bank exceeds 50% of net
profits, after taxes but before dividends, for the previous calendar year; or
(c) the percentage of the Bank's assets classified as doubtful as to repayment
exceeds 80% of the Bank's equity capital. At December 31, 1994, total
stockholder's equity of Georgia was $10,605,463 of which approximately $324,000
was available for dividends without prior approval or violation of regulatory
capital requirements. Gwinnett can pay no dividends until its accumulated
deficit is eliminated. The Banks paid no dividends in 1994 or 1993.
 
     The Banks are required to maintain certain capital ratios as defined by the
regulatory authorities. At December 31, 1994, the Banks are required to have a
minimum total risk-based capital ratio of 8% and a minimum leverage ratio of 4%.
Georgia's total risk-based capital ratio at that date was 11.5%, and its
leverage ratio was 7.7%. Gwinnett's risk-based capital ratio at that date was
12.7%, and its leverage ratio was 8.5%.

NOTE M.  COMMITMENTS AND CONTINGENT LIABILITIES
 
     The Banks are party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers.
These financial instruments include commitments to extend credit and standby
letters of credit. These instruments involve, to varying degrees, elements of
credit and interest rate risk in excess of the amount recognized in the
consolidated balance sheets. The contract amounts of these instruments reflect
the extent of involvement the Banks have in particular classes of financial
instruments.
 
     The Banks' exposure to credit loss in the event of nonperformance by the
customer on the financial instrument for commitments to extend credit and
standby letters of credit is represented by the contractual amounts of those
instruments. The Banks use the same credit policies in making commitments and
conditional obligations as they do for on-balance-sheet instruments.
 
     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since many of the commitments are expected to
expire without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. At December 31, 1994 and 1993, unfunded
commitments to extend credit were approximately $38,317,000 and $35,054,000,
respectively.
 
     Standby letters of credit are conditional commitments issued by the Banks
to guarantee the performance of a customer to a third party. Those guarantees
are primarily issued to support public and private borrowing arrangements. The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loans to customers. The Banks had approximately
$1,184,000 and $1,607,000 in irrevocable standby letters of credit outstanding
at December 31, 1994 and 1993, respectively.
 
     The Banks evaluate each customer's creditworthiness on a case-by-case
basis. The amount of collateral obtained, if deemed necessary by the Banks upon
extension of credit, is based on management's credit evaluation of the
counterparty. Collateral varies but may include accounts receivable, inventory,
property, plant and equipment, and income-producing commercial properties for
those commitments on which collateral is deemed necessary.
 
     The Company is a defendant in certain legal actions arising from its normal
business activities. Management believes that those actions are without merit or
that the ultimate liability, if any, resulting from them will not materially
affect the Company's financial position.

NOTE E.  ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 121 (SFAS 121), "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The Company is
required to implement SFAS No. 121 by December 31, 1996. The provisions of SFAS
121 will require the Company to review long-lived assets for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. If it is determined that an impairment loss has occurred
based on expected future cash flows, the loss should be recognized in the income
statement and certain disclosures regarding the impairment should be made in the

statements. The Company has not yet had sufficient time to evaluate the impact,
if any, of the provisions of SFAS No. 121.
 
NOTE F.  ACCOUNTING FOR MORTGAGE SERVICING RIGHTS
 
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 122 (SFAS 122), "Mortgage Servicing Rights," as an
amendment to SFAS 65. The Company is required to implement SFAS 122 by December
31, 1996. The provisions of SFAS 122 eliminate the accounting distinction
between rights to service mortgage loans that are acquired through loan
origination and those acquired through purchase. The cost of mortgage loans sold
should be allocated to the mortgage servicing rights and the loans based on
relative fair values. The adoption of SFAS No. 122 is not expected to have a
significant impact on the Company.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Directors
Southern Banking Corporation and Subsidiary
Altamonte Springs, Florida
 
     We have audited the accompanying consolidated balance sheets of Southern
Banking Corporation and Subsidiary as of December 31, 1994 and 1993, and the
related consolidated statements of income, stockholders' equity, and cash flows
for each of the three years in the period ended December 31, 1994. These
consolidated financial statements are the responsibility of the 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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Southern
Banking Corporation and Subsidiary as of December 31, 1994 and 1993, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1994, in conformity with generally accepted
accounting principles.
 
     As discussed in Note 2, effective January 1, 1994, the Company adopted
Statement of Financial Accounting Standards No. 115, Accounting for Certain
Investments in Debt and Equity Securities and as discussed in Note 6, the
Company changed its method of accounting for income taxes in the period ended
December 31, 1993.

1. ORGANIZATION
 
     Southern Bank Corporation (the Company) is a bank holding company with a
wholly-owned subsidiary, Southern Bank of Central Florida (the Bank), a
state-chartered bank headquartered in Altamonte Springs, Florida. The Company
commenced operations on August 29, 1988. As of December 31, 1994,the bank
operates eight branches: four in Seminole County, two in Osceola County and two
in Orange County. The Company's deposits are insured by the Federal Deposit
Insurance Corporation.
 
     On September 30, 1994, the Bank acquired substantially all of the
outstanding common stock of Osceola National Bank (ONB). The acquisition has
been accounted for under the purchase method, whereby the purchase price of
$6,069,000 has been allocated to the underlying assets and liabilities based on
their respective fair values at the date of acquisition. A summary of the
purchase price allocation as reflected in the accompanying Consolidated Balance
Sheets is as follows:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies of the Company are in accordance with
generally accepted accounting principles, and conform to general practices
within the banking industry.
 
     Method of Consolidation.  In consolidation, all significant intercompany
accounts and transactions are eliminated.
 
     Cash and Cash Equivalents.  Cash and cash equivalents include cash on hand,
amounts due from banks, and federal funds sold.
 
     Investment Securities.  Investment securities are carried at cost adjusted
for amortization of premium and accretion of discount. Gains and losses on the
sale of securities are computed by specific identification.
 
     Effective January 1, 1994, the Company adopted the provisions of Statement
of Financial Accounting Standards No. 115 (SFAS No. 115), Accounting for Certain
Investments in Debt and Equity Securities, that addresses the accounting and
reporting for investments in marketable equity securities and for all
investments in debt securities. SFAS No. 115 requires investments in debt and
marketable equity securities to be classified in three categories and accounted
for as follows: held to maturity (recorded at amortized cost), available for
sale (recorded at fair value with unrealized gains and losses reported as a
separate component of stockholder's equity), and trading securities (recorded at
fair value with unrealized gains and losses included in earnings).
 
     In accordance with the Statement, prior period financial statements have
not been restated to reflect the change in accounting principle. The cumulative
effect of adopting SFAS No. 115 as of January 1, 1994 was a decrease in the
opening balance of stockholders' equity of $7,636 (net of $4,607 in deferred
income taxes) to reflect the unrealized losses on securities classified as
available-for-sale that were previously classified as investment securities and
carried at amortized cost.
 
     Loans and Allowance for Loan Losses.  Interest on loans is accrued by the
simple interest method. Loan origination fees and incremental costs are deferred
and amortized over the life of the loans as a yield
 
                                      F-55

                  SOUTHERN BANKING CORPORATION AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
adjustment. The interest recognition methods produce relatively constant yields
over the terms of the loans. Accrual of interest is discontinued on a loan when
management believes, after considering economic and business conditions and
collection efforts, that the borrower's financial condition is such that
collection of interest is doubtful.
 
     The allowance for loan losses is maintained at a level determined to be
adequate for potential loan losses and considers delinquencies, recent loss
experience and the general condition of the loan portfolio, as well as
prevailing and anticipated economic conditions.
 
     In May 1993, the FASB issued SFAS No. 114, Accounting by Creditors for
Impairment of a Loan, which establishes new guidance for all creditors in
determining allowances for credit losses related to certain loans. The standard
requires impaired loans to be recorded using one of the following basis: the
present value of expected future cash flows, the loan's observable market price,
or the fair value of the collateral. This statement is effective for fiscal
years beginning after December 31, 1994. The Company has elected not to
implement SFAS No. 114 for 1994. The effect of this standard is not expected to
be adverse or material.
 
     Premises and Equipment.  Depreciable assets are stated at cost, less
accumulated depreciation and amortization. Depreciation and amortization is
provided on the straight-line basis over the estimated useful lives of the
assets. Maintenance and repairs are charged to expense as incurred and major
renewals and betterments are capitalized. Gains or losses are credited or
charged to income upon disposition.
 
     Goodwill.  The Bank recorded goodwill for the excess of the purchase price
of Osceola National Bank over the estimated fair value of the net assets
acquired. The goodwill is being amortized on a straight-line basis over 20
years. Amortization expense for 1994 was $30,541.
 
     Income Taxes.  Income taxes are provided for the tax effects of
transactions reported in the financial statements and consist of taxes currently
due plus deferred taxes resulting from temporary differences. Such temporary
differences result from differences in the carrying value of assets and
liabilities for tax and financial reporting purposes. The deferred tax assets
and liabilities represent the future tax consequences of those differences,
which will either be taxable or deductible when the assets and liabilities are
recovered or settled. Valuation allowances are established when necessary to
reduce deferred tax assets to the amount expected to be realized. Income tax
expense is the tax payable for the period and the change during the period in
deferred tax assets and liabilities.
 
     Net Income per Common Share.  Net Income per common share has been computed
using the weighted average number of shares outstanding during the year.

     During 1994, the Company adopted an employee stock appreciation plan in
which hypothetical investments in shares of the Company's common stock are
awarded to key employees. The benefits vest over 5 years and are paid at the
close of the vesting period based upon the appreciation of the shares between
the date of grant and the exercise date. Under the plan, 79,000 shares were
granted, none of which were exercised or cancelled as of December 31, 1994.
Compensation expense pursuant to the plan was immaterial in 1994.
 
8. EMPLOYEE BENEFIT PLAN
 
     Effective January 1, 1993, the Company adopted a deferred savings plan
under Internal Revenue Code Section 401(k), which covers substantially all of
the Company's employees who meet minimum length of service requirements. Under
the provisions of the plan, employees may contribute up to 15% of their
compensation on a pre-tax basis. The Company matches the employee contribution
25% up to a maximum of 4%. The Company's contribution to the plan was $26,431
and $13,955 for the years ended December 31, 1994 and 1993, respectively.

     Rent expense was approximately $385,000, $342,000 and $417,000 for 1994,

     In November 1994, the Bank entered into an option for assignment of lease
and purchase of fixed assets related to the leased property formerly known as
the Orlando branch. As of December 31, 1994, this option has not been exercised
by the sublessee.
 
     Financial Instruments with Off-Balance Sheet Risks.  The Bank is a party to
financial instruments with off-balance sheet risk in the normal course of its
business to meet the financing needs of its customers and to

reduce its own exposure to fluctuations in interest rates. These financial
instruments include loan commitments and stand-by letters of credit. These
instruments involve, to varying degrees, elements of credit and interest rate
risk in excess of the amount recognized in the financial statements.
 
     The Bank's exposure to credit loss in the event of nonperformance by the
other party to its financial instrument for loan commitments and stand-by
letters of credit is represented by the contracted amount of those instruments.
The Bank uses the same credit policies in making commitments and conditional
obligations as it does for on-balance sheet instruments.
 
     At December 31, 1994 and 1993, the Bank has commitments to customers of
approximately $1,877,000 and $928,000 for standby letters of credit and
$33,162,000 and $17,948,000 for unfunded firm loan commitments, respectively.
Since many of the loan commitments may expire without being drawn upon, the
total commitment amount does not necessarily represent future cash requirements.
 
     Financial Instruments with Off-Balance Sheet Risks.  The Bank has no
significant concentration of credit risk with any individual counterparty to
originate loans. Bank loan customers are principally closely-held businesses and
residents concentrated in the central Florida area and as such, the debtors'
ability to honor their contract is substantially dependent upon the general
economic conditions of the region.
 
     The Bank evaluates each customer's credit worthiness on a case-by-case
basis. It is the Bank's policy to obtain adequate collateral in accordance with
internal lending guidelines on all loans. Unsecured loans are made based upon
the judgment of Company management in accordance with authorized lending limits,
Bank lending policies and credit criteria. Collateral on the Bank's loans depend
on the nature of the loan, and are principally commercial and residential real
property and other commercial tangible assets (inventory and equipment). It is
the Bank's policy to perfect its interest in the collateral through the filing
of mortgage deeds and uniform commercial code (UCC) filings, or taking physical
possession of the collateral, if appropriate. Bank management believes it has
access to collateral in the event of loan default to minimize its credit risk.
 
     Stand-by letters of credit are conditional commitments issued by the Bank
to guarantee the performance of a customer to a third party. The credit risk
involved in issuing letters of credit is essentially the same as that involved
in extending loan facilities to customers. The collateral varies for those
commitments, but may include a certificate of deposit held by the Bank if
collateral is deemed necessary.
 
     During 1994 and 1993, the Bank has approximately $35,594,000 and
$17,514,000, respectively, in fixed rate loans with interest rates ranging from
5.5% to 18%, and $19,215,000 and $191,000, respectively, in variable rate loans
with interest rate ceilings ranging from 9% to 18%.
 
     The Bank is required to maintain a minimum leverage capital ratio of Tier I
capital, as defined, to total assets based upon the Company's ratings under the
regulatory CAMEL rating system. Banks with CAMEL ratings of one are required to
maintain a minimum leverage capital ratio of 3 percent. An additional 100 to 200
basis points are required for banks with CAMEL ratings other than one.
 
     The Bank must also maintain a ratio of total capital to risk-weighted
assets of 8 percent, and a ratio Tier I capital to risk-weighted assets of 4
percent.
 
10. RETAINED EARNINGS
 
     The Company's retained earnings account at December 31, 1994 and 1993
includes $1,060,000 of initial paid-in capital.
 
     The payment of dividends by the Bank is subject to certain regulatory
restrictions.

Stock which shall be equal to $2,600,000 divided by the total number of shares
of Bank Stock outstanding, divided in turn by the Market Value. 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 (10) trading days ending on the trading day immediately preceding the
Effective Date. In addition, BancGroup will pay an aggregate of $2,600,000 in
cash for the outstanding shares of Bank Stock, with the amount of cash to be
paid for each one share of Bank Stock equal to $2,600,000 divided by the number
of shares of Bank Stock outstanding.
 
     (ii) A holder of Bank Stock may, prior to the Stockholders Meeting, file a
written election form (an "Election Form") with the Bank specifying whether such
holder prefers to have the Merger Consideration paid to such holder in shares of
BancGroup Common Stock only, cash only, or a proportion of cash and BancGroup
Common Stock that is other than 50% for each, provided that, notwithstanding any
elections made pursuant to such Election Forms, the aggregate number of shares
of BancGroup Common Stock to be distributed in the Merger shall equal 50% of the
total Merger Consideration and the aggregate amount of cash to be paid in the
Merger shall equal 50% of the total Merger Consideration. Elections made shall
apply to all shares of record of Bank Stock held by a record holder making the
election. If the aggregate amount of cash to be paid in the Merger is less than
50% of the Merger Consideration based upon the Election Forms which have been
properly filed, then a sufficient amount of additional cash shall be distributed
pro rata to all
 
                                       A-6
<PAGE>   150
 
stockholders of the Bank who have not elected to receive 100% of the Merger
Consideration in cash, regardless of whether such stockholders have filed an
Election Form, so that the aggregate amount of Merger Consideration to be paid
in cash in the Merger will equal 50%, and the number of shares of BancGroup
Common Stock otherwise required to be distributed shall be reduced pro rata as
to all stockholders who have not elected to receive 100% of the Merger
Consideration in cash. If the aggregate amount of cash to be paid in the Merger
is greater than 50% of the Merger Consideration based upon the Election Forms
which have been properly filed, then a sufficient amount of cash shall be
distributed pro rata to all stockholders of the Bank who have not elected to
receive 100% of the Merger Consideration in BancGroup Common Stock, regardless
of whether such stockholders have filed an Election Form, so that the aggregate
amount of Merger Consideration to be paid in cash in the Merger will equal 50%,
and the number of shares of BancGroup Common Stock otherwise required to be
distributed shall be increased pro rata as to all stockholders who have not
elected to receive 100% of the Merger Consideration in BancGroup Common Stock.
For purposes of this section 3.1(a), and in accordance with section 3.6, cash to
be paid to holders exercising dissenter's rights of appraisal under section 3.6
hereof shall be included as part of the Merger Consideration for determining the
amount of cash to be paid under section 3.1(a). Interest will not be paid on any
cash to be paid as part of the Merger Consideration.
 
     3.2 Surrender of Bank Stock.  After the Effective Date, each holder of an
outstanding certificate or certificates which prior thereto represented shares
of Bank Stock who is entitled to receive BancGroup Common Stock shall be
entitled, upon surrender to BancGroup of their certificate or certificates
representing shares of Bank Stock, 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 Bank 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 Bank 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 Bank
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 Bank 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 Bank 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 Common Stock,
an appropriate and proportionate adjustment shall be made in the number of
shares of BancGroup Common Stock into which the Bank Stock shall be converted.
 
     3.5 Colonial Bank Stock.  The shares of common stock of Colonial Bank
issued and outstanding immediately before the Effective Date shall continue to
be issued and outstanding shares of the Resulting Corporation.
 
     3.6 Dissenting Rights.  Any shareholder of the Bank who shall not have
voted in favor of this Agreement and has complied with the applicable procedures
set forth in the regulations of the Office of Thrift Supervision, relating to
rights of dissenting shareholders, shall be entitled to receive payment for the
fair value of his Bank Stock. If after the Effective Date a dissenting
shareholder of the Bank fails to perfect, or effectively withdraws or loses, his
right to appraisal and payment for his shares of Bank Stock, BancGroup shall
issue and deliver the consideration to which such holder of shares of Bank Stock
is entitled under Section 3(a) (without interest) upon surrender of such holder
of the certificate or certificates representing shares of Bank Stock held by
him. The $2,600,000 figure stated in section 3.1(a) used for calculating the
cash to be distributed to holders of Bank Stock shall be reduced by an amount
that equals the number of shares of Bank Stock properly exercising dissenting
rights of appraisal under this section multiplied by $13.01.

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 on the
condition (financial or other), earnings, business, affairs, Assets, properties,
prospects or results of operations of BancGroup or of BancGroup and its
Subsidiaries taken as a whole.
 
     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

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

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

is a party or by which they or any material portion of their Assets may be
bound; will not conflict with any provision of the restated certificate of

encumbrances except (i) mortgages and other encumbrances referred to in the

to transact business and is in good standing under the Laws of each other

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
against or affecting BancGroup or any of its Subsidiaries (nor is BancGroup
aware of any facts which could give rise to any such Litigation) which is
required to be disclosed in the Registration Statement (other than as disclosed

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

commitment which is material to the business, operations, property, prospects or
Assets or to the condition, financial or otherwise, of the Bank. Complete and
accurate copies of all Contracts, plans and other items so listed have been made
or will be made available to BancGroup for inspection. Prior to the Effective
Date, the Bank will not enter into or amend any Contract, agreement or other
instrument of any of the types listed in this section without giving five days
prior written notice to BancGroup, provided that such notice shall not impair

     5.8 Charter and Bylaws.  Schedule 5.8 contains true and correct copies of
the Bank's federal stock charter and bylaws, including all amendments thereto,
as currently in effect. There will be no changes in such charter or bylaws prior

behalf of the Bank) pending or, to the Knowledge of the Bank, threatened against
or affecting (nor is the Bank aware of any facts which could give rise to any
such Litigation) at law or in equity, or before or by any governmental
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 the
business operations, properties or Assets or in the condition, financial or
otherwise, of the Bank, and the Bank is not 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 the
business operations, properties or Assets or in the condition, financial or
otherwise, of such party. To the Knowledge of the Bank, the Bank has complied in
all material respects with all material applicable Laws including those imposing
Taxes, or 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 in the business operations, properties or Assets
or in the condition, financial or otherwise, of the Bank.
 
     5.10 Material Contract Defaults.  The Bank is not in Default in any
material respect under the terms of any 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 the Bank and, to the
Knowledge of the Bank, there is no event which, with notice or lapse of time, or
both, may be or become an event of Default under any such 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 or
constitute a Default (without regard to the giving of notice or the passage of
time, or both) under any term or provision of any Contract, indenture, mortgage,
deed of trust or other material agreement or instrument to which the Bank is a
party or its Assets may be bound and will not conflict with any provision of the
stock charter or bylaws of the Bank.
 
     5.12 Governmental Authorization.  The Bank has all licenses, franchises,
permits and other governmental authorizations that, to the Knowledge of the
Bank, are or will be legally required to enable the Bank to conduct its business
in all material respects as now conducted by the Bank.
 
     5.13 Absence of Regulatory Communications.  The Bank is not subject to, nor
has the Bank received during the past three years, any written communication
directed specifically to it from any Agency to which it is subject or pursuant
to which such Agency has imposed or has indicated it may impose any 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 the Bank.
 
     5.14 Absence of Material Adverse Change.  Since the date of the most recent
balance sheet provided under section 5.4(a)(i), there have been no events,
changes or occurrences which have had, or are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on the Bank.
 
     5.15 Insurance.  The Bank has in effect insurance coverage and bonds with
reputable insurers which, in respect to amounts, types and risks insured,
management of the Bank reasonably believes to be adequate for
 
                                      A-14
<PAGE>   158
 
the type of business conducted by such company. The Bank is not liable for any
material retroactive premium adjustment. All insurance policies and bonds are
valid, enforceable and in full force and effect, and the Bank has not received
any notice of a premium increase or cancellation with respect to any of its
insurance policies or bonds. Within the last three years, the Bank has not 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 the Bank at all times from the date hereof to the
Effective Date.
 
     5.16 Pension and Employee Benefit Plans.  (a) To the Knowledge of the Bank,
all employee benefit plans of the Bank have been established in compliance with,
and such plans have been operated in material compliance with, all applicable
Laws. Except as set forth on Schedule 5.16, the Bank has no pension or other
retirement plan or any other plan or agreement subject to ERISA or Section 401
of the Code, and no unfunded Liabilities exist with respect to any employee
benefit plan, past or present. To the Knowledge of the Bank, 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 the Bank.
 
     (b) The Bank has no reason to believe that any amount payable to any
employee of the Bank 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.  The Bank is not aware of any agreement 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 the Bank, any similar agreement or any voting
agreement or voting trust in respect of any such shares.
 
     5.18 Brokers.  All negotiations relative to this Agreement and the
transactions contemplated by this Agreement have been carried on by the Bank
directly with BancGroup and without the intervention of any other person, either
as a result of any act of the Bank, or otherwise, in such manner as to give rise
to any valid claim against the Bank for a finder's fee, brokerage commission or
other like payment, except for the services of Steven Johnson & Associates.
 
     5.19 Approval of Agreements.  The board of directors of the Bank has
approved this Agreement and the transactions contemplated by this Agreement and
has authorized the execution and delivery by the Bank of this Agreement. Subject
to the matters referred to in section 8.2, the Bank has full power, authority
and legal right to enter into this Agreement, and, upon appropriate vote of the
shareholders of the Bank in accordance with this Agreement, the Bank shall have
full power, authority and legal right to consummate the transactions
contemplated by this Agreement. Subject to the conditions set forth herein, this
Agreement represents a legal, valid, and binding obligation of the Bank,
enforceable against the Bank in accordance with its terms (except in all cases
as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar Laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceeding may be brought).
 
     5.20 Disclosure.  No representation or warranty, nor any statement or
certificate furnished or to be furnished to BancGroup by the Bank, 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
 
                                      A-15
<PAGE>   159
 
apply to statements in or omissions from the Proxy Statement relating to
descriptions of the business of the Bank, its Assets, properties, operations,
and capital stock or to information furnished by the Bank or its 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 the Bank are
adequate in all material respects, and the Bank 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 the Bank 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.
Except as disclosed on Schedule 5.22, the Bank does not have in its portfolio
any loan exceeding its legal lending limit, and the Bank has no known
significant delinquent, substandard, loss, or nonperforming loans.
 
     5.23 Environmental Matters.  To the Knowledge of the Bank, the Bank is in
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 the Bank has no
Knowledge that the Bank has not complied with all regulations and requirements
promulgated by the Occupational Safety and Health Administration that are
applicable to the Bank. To the Knowledge of the Bank, there is no Litigation
proceeding, suit or investigation pending or threatened with respect to any
violation or alleged violation of the Environmental Laws. To the Knowledge of
the Bank, with respect to properties or Assets of or owned by the Bank,
including any Loan Property, (i) there has been no spillage, leakage,
contamination or release of any substances for which the appropriate remedial
action has not be 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 the Bank. The Bank
has no Knowledge of any facts which might suggest that the Bank has engaged in
any management practice with respect to any of its past or existing borrowers
which could reasonably be expected to subject the Bank 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 the Bank, the Bank has not 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, licenses, and other authorizations which are required
under any Environmental Law.
 
     5.24 Transfer of Shares.  The Bank has no Knowledge of any plan or
intention on the part of the Bank'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 Bank common stock outstanding immediately before the
Merger.
 
     5.25 Collective Bargaining.  There are no labor contracts, collective
bargaining agreements, letters of understanding or other arrangements, formal or
informal, between the Bank and any union or labor organization covering any of
the Bank's employees and none of said employees are represented by any union or
labor organization.
 
     5.26 Labor Disputes.  The Bank is in material compliance with all federal
and state laws respecting employment and employment practices, terms and
conditions of employment, wages and hours. The Bank is not and has not been
engaged in any unfair labor practice, and, to the Knowledge of the Bank, no
unfair labor practice complaint against the Bank is pending before the National
Labor Relations Board. Relations between management and the employees are
amicable and there have not been, nor to the Knowledge of the Bank are there
presently, any attempts to organize employees, nor to the Knowledge of the Bank
are there plans for any such attempts.
 
     5.27 Derivative Contracts.  The Bank is not a party to and has not agreed
to enter into a swap, forward, future, option, cap, floor or collar financial
contract, or any other interest rate or foreign currency protection
 
                                      A-16

contract or derivative security not included in the Bank's financial statements
delivered under section 4.3 hereof which is a financial derivative contract
(including various combinations thereof).

     8.5 Tax Opinion.  An opinion of Miller, Hamilton, Snider & Odom, counsel to
BancGroup, shall have been received in form and substance reasonably
satisfactory to the Bank and BancGroup to the effect that (i) the Merger will
constitute a "reorganization" within the meaning of section 368 of the code;
(ii) no gain or loss will be recognized by the Bank; (iii) no gain or loss will
be recognized to the shareholders of the Bank who receive shares of BancGroup
Common Stock except to the extent of any taxable "boot" received by such persons
from BancGroup, and except to the extent of any dividends received from the Bank
prior to the Effective Date; (iv) the basis of the BancGroup Common Stock
received in the Merger will be equal to the sum of the basis of the shares of
Bank common stock exchanged in the Merger and the amount of gain, if any, which
was recognized by the exchanging Bank shareholder, including any portion treated
as a dividend, less the value of taxable boot, if any, received by such
shareholder in the Merger; (v) the holding period of the BancGroup Common Stock
will include the holding period of the shares of Bank common stock exchanged
therefor if such shares of bank common stock were capital assets in the hands of
the exchanging Bank shareholder; and (vi) cash received by a Bank stockholder in
lieu of a fractional share interest of BancGroup stock will be treated as having
been received as a distribution in full payment in exchange for the fractional
share interest of BancGroup Common Stock which he would otherwise be entitled to
receive and will qualify as capital gain or loss (assuming the Bank common stock
was a capital asset in his hands as of the Effective Date).

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining terms and provisions thereof or affecting the
validity or enforceability of such provision in any other jurisdiction, and if
any term or provision of this Agreement is held by any court of competent
jurisdiction to be void, voidable, invalid or unenforceable in any given
circumstance or situation, then all other terms and provisions, being severable,
shall remain in full force and effect in such circumstance or situation and the

remedies at law that may be available to the non-breaching Party, the
non-breaching Party shall be entitled to obtain equitable relief, including the
remedies of specific performance and injunction, in the event of a breach of
this Agreement by the other Party, and no attempt on the part of the

power or remedy, or an acquiescence in any similar breach or Default; nor shall
any waiver of any single breach or Default be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit,
consent or approval of any kind or character on the part of any Party of any
provisions of this Agreement must be in writing and be executed by the Parties
to this Agreement and shall be effective only to the extent specifically set
forth in such writing.

or otherwise, shall be cumulative and not alternative.

Agreement and supersede all other understandings with respect to the subject
matter of this Agreement.

required for a combination made pursuant to sec. 552.13(h)(2) of this part.
"Qualified consideration" means cash, shares of stock of any association or
corporation which at the effective date of the combination will be listed on a
national securities exchange or quoted on NASDAQ, or any combination of such
shares of stock and cash.
 
     (c) Procedure-(1) Notice.  Each constituent Federal stock association shall
notify all stockholders entitled to rights under this section, not less than
twenty days prior to the meeting at which the combination agreement is to be
submitted for stockholder approval, of the right to demand payment of appraised
value of shares, and shall include in such notice a copy of this section. Such
written notice shall be mailed to stockholders of record and may be part of
management's proxy solicitation for such meeting.
 
     (2) Demand for appraisal and payment.  Each stockholder electing to make a
demand under this section shall deliver to the Federal stock association, before
voting on the combination, a writing identifying himself or herself and stating
his or her intention thereby to demand appraisal of and payment for his or her
shares. Such demand must be in addition to and separate from any proxy or vote
against the combination by the stockholder.
 
     (3) Notification of effective date and written offer.  Within ten days
after the effective date of the combination, the resulting association shall:
 
          (i) Give written notice by mail to stockholders of constituent Federal
     stock associations who have complied with the provisions of paragraph
     (c)(2) of this section and have not voted in favor of the combination, of
     the effective date of the combination;
 
          (ii) Make a written offer to each stockholder to pay for dissenting
     shares at a specified price deemed by the resulting association to be the
     fair value thereof; and
 
          (iii) Inform them that, within sixty days of such date, the respective
     requirements of paragraphs (c)(5) and (c)(6) of this section (set out in
     the notice) must be satisfied.
 
     The notice and offer shall be accompanied by a balance sheet and statement
of income of the association the shares of which the dissenting stockholder
holds, for a fiscal year ending not more than sixteen months before the date of
notice and offer, together with the latest available interim financial
statements.
 
     (4) Acceptance of offer.  If within sixty days of the effective date of the
combination the fair value is agreed upon between the resulting association and
any stockholder who has complied with the provisions of paragraph (c)(2) of this
section, payment therefor shall be made within ninety days of the effective date
of the combination.
 
     (5) Petition to be filed if offer not accepted.  If within sixty days of
the effective date of the combination the resulting association and any
stockholder who has complied with the provisions of paragraph (c)(2) of this
section do not agree as to the fair value, then any such stockholder may file a
petition with the Office, with a copy by registered or certified mail to the
resulting association, demanding a determination of the fair market
 
                                       B-1
<PAGE>   174
 
value of the stock of all such stockholders. A stockholder entitled to file a
petition under this section who fails to file such petition within sixty days of
the effective date of the combination shall be deemed to have accepted the terms
offered under the combination.
 
     (6) Stock certificates to be noted.  Within sixty days of the effective
date of the combination, each stockholder demanding appraisal and payment under
this section shall submit to the transfer agent his certificates of stock for
notation thereon that an appraisal and payment have been demanded with respect
to such stock and that appraisal proceedings are pending. Any stockholder who
fails to submit his or her stock certificates for such notation shall no longer
be entitled to appraisal rights under this section and shall be deemed to have
accepted the terms offered under the combination.
 
     (7) Withdrawal of demand.  Notwithstanding the foregoing, at any time
within sixty days after the effective date of the combination, any stockholder
shall have the right to withdraw his or her demand for appraisal and to accept
the terms offered upon the combination.
 
     (8) Valuation and payment.  The Director shall, as he or she may elect,
either appoint one or more independent persons or direct appropriate staff of
the Office to appraise the shares to determine their fair market value, as of
the effective date of the combination, exclusive of any element of value arising
from the accomplishment or expectation of the combination. Appropriate staff of
the Office shall review and provide an opinion on appraisals prepared by
independent persons as to the suitability of the appraisal methodology and the
adequacy of the analysis and supportive data. The Director after consideration
of the appraisal report and the advice of the appropriate staff shall, if he or
she concurs in the valuation of the shares, direct payment by the resulting
association of the appraised fair market value of the shares, upon surrender of
the certificates representing such stock. Payment shall be made, together with
interest from the effective date of the combination, at a rate deemed equitable
by the Director.
 
     (9) Costs and expenses.  The costs and expenses of any proceeding under
this section may be apportioned and assessed by the Director as he or she may
deem equitable against all or some of the parties. In making this determination
the Director shall consider whether any party has acted arbitrarily,
vexatiously, or not in good faith in respect to the rights provided by this
section.
 
     (10) Voting and distribution.  Any stockholder who has demanded appraisal
rights as provided in paragraph (c)(2) of this section shall thereafter neither
be entitled to vote such stock for any purpose nor be entitled to the payment of
dividends or other distributions on the stock (except dividends or other
distribution payable to, or a vote to be taken by stockholders of record at a
date which is on or prior to, the effective date of the combination): Provided,
That if any stockholder becomes unentitled to appraisal and payment of appraised
value with respect to such stock and accepts or is deemed to have accepted the
terms offered upon the combination, such stockholder shall thereupon be entitled
to vote and receive the distributions described above.
 
     (11) Status.  Shares of the resulting association into which shares of the
stockholders demanding appraisal rights would have been converted or exchanged,
had they assented to the combination, shall have the status of authorized and
unissued shares of the resulting association.

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 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
<PAGE>   179

                          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
                          final adjudication of such issue.

         (b)     The undersigned Registrant hereby undertakes to respond to
                 requests for information that is incorporated by reference
                 into the prospectus pursuant to Items 4, 10(b), 11, or 13 of
                 Form S-4, within one business day of receipt of such request,
                 and to send the incorporated documents by first class mail or
                 other equally prompt means.  This includes information
                 contained in documents filed subsequent to the effective date
                 of the Registration Statement through the date of responding
                 to the request.

         (c)     The undersigned Registrant hereby undertakes to supply by
                 means of a post-effective amendment all information concerning
                 a transaction, and the company being acquired involved
                 therein, that was not the subject of and included in the
                 Registration Statement when it became effective.

         (d)     The undersigned Registrant hereby undertakes:

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

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

                          (ii)    To reflect in the prospectus any facts or
                                  events arising after the effective date of
                                  the Registration Statement (or the most
                                  recent post-effective amendment thereof)
                                  which, individually or in the aggregate,
                                  represent a fundamental change in the
                                  information set forth in the Registration
                                  Statement;
<PAGE>   180

                          (iii)   To include any material information with
                                  respect to the plan of distribution not
                                  previously disclosed in the Registration
                                  Statement or any material change to such

         Re:     Registration Statement on Form S-4 relating to the issuance of
                 shares of Common Stock of The Colonial BancGroup, Inc., in
                 connection with the acquisition by merger of Dothan Federal
                 Savings Bank ("Merger")

Gentlemen:

         We are familiar with the proceedings taken and proposed to be taken by
The Colonial BancGroup, Inc., a Delaware corporation (the "Company"), in
connection with the proposed issuance by the Company of shares of its Common
Stock, par value of $2.50 per share, in connection with the Merger and in
accordance with an Agreement and Plan of Merger, dated as of January 22, 1996
(the "Agreement"), by and between the Company, Colonial Bank and Dothan Federal
Savings Bank.  We have also acted as counsel for the Company in connection with
the preparation and filing with the Securities and Exchange Commission under
the Securities Act of 1933, of the Registration Statement on Form S-4 referred
to in 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
opinions expressed herein.

         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 shares of Common Stock of the Company;

         (iii)   Under the laws of the State of Delaware, no personal liability
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
above-referenced registration statement.  In consenting to the inclusion of our
opinion in the Registration Statement, we do not thereby admit that we are a

Dothan Federal Savings Bank
1962 West Main Street
Dothan, Alabama 36302

         Re:  Tax Opinion

Gentlemen:

         We have acted as counsel to The Colonial BancGroup, Inc., a Delaware
corporation ("BancGroup"), in connection with the merger (the "Merger") of
Dothan Federal Savings Bank (the "Bank") with and into BancGroup's wholly-owned
subsidiary, Colonial Bank ("Colonial Bank"), pursuant to the Agreement and Plan
of Merger, dated as of January 22, 1996 (the "Agreement") by and between
BancGroup, Colonial Bank and the Bank.  This opinion is being rendered to you
pursuant to paragraph 8.5 of the Agreement.

         In rendering this opinion, we have relied upon the facts, which are
not restated herein, but rather, as they have been presented to us in the
Agreement, and in a preliminary joint proxy statement-prospectus of the Bank,
Colonial Bank and BancGroup to be filed with the Securities and Exchange
Commission.  We have assumed, with your consent, that the facts presented to us
provide an accurate and complete description of the facts and circumstances
concerning the proposed transaction.  Any changes to the facts,
representations, or documents referred to in this opinion may affect the
conclusions stated herein.

         In connection with this opinion, we have assumed, with your consent,
the following:

         (1)     BancGroup does not plan to sell or otherwise dispose of any of
the stock of
<PAGE>   2
February 8, 1996
Page 2

Colonial Bank or to liquidate Colonial Bank after the Merger.

         (2)     Colonial Bank will continue the historic business of the Bank
or will use a significant portion of the historic business assets of the Bank
in a business.

         (3)     The Bank has no knowledge of any plan or intention on the part
of its shareholders to sell or otherwise dispose of the BancGroup common stock
to be received by them that would reduce their holdings to a number of shares
having, in the aggregate, a fair market value of less than fifty percent of the
total fair market value of the Bank common stock outstanding immediately before
the Merger.

         (4)     As a result of the Merger, each share of the issued and
outstanding Bank common stock will be converted into the right to receive
BancGroup common stock.

         (5)     No fractional shares will be issued in the Merger.  In the
event fractional shares result in the exchange, the Bank shareholders entitled
to fractional shares will be paid cash by BancGroup for their fractional
shares.

         (6)     The fair market value of the BancGroup common stock to be
received by the Bank shareholders will be approximately equal to the fair
market value of the Bank stock exchanged therefor.

         (7)     The proposed Merger will be effected for substantial non-tax
business purposes.

         (8)     Colonial Bank will acquire at least 90% of the fair market
value of the net assets and at least 70% of the fair market value of the gross
assets held by the Bank immediately prior to the Merger.  For purposes of this
representation, Bank assets used to pay its reorganization expenses, and all
redemptions and distributions (except for regular, normal dividends) made by
the Bank immediately preceding the Merger and all payments to dissenters, if
any, will be included as assets of the Bank held immediately prior to the
Merger.

         (9)     The Bank is not under the jurisdiction of a court in a Title
11 or similar case within the meaning of Section  368(a)(3)(A) of the Internal
Revenue Code of 1986, as amended (the "Code").

         On the basis of the foregoing and our consideration of such other
matters as we have considered necessary, we advise you that, in our opinion,
for federal income tax purposes:

         (1)     The merger of the Bank with and into Colonial Bank in
accordance with the terms of the Agreement will constitute a reorganization
within the meaning of Sections 368(a)(1)(A) and 368 (a)(2)(D) of the Code.  The
Bank, Colonial Bank and BancGroup will
<PAGE>   3
February 8, 1996
Page 3

each be a "party to a reorganization" under Section 368(b) of the Code.

         (2)     No gain or loss will be recognized by the Bank upon the
transfer of its assets and liabilities to Colonial Bank.  Sections 357(a) and
361(a) of the Code.

         (3)     A Bank shareholder who exchanges shares of Bank stock for a
combination of BancGroup common stock and cash as described in the Agreement
shall recognize gain, if any, but in an amount not in excess of the sum of such
cash received.  The amount of the gain realized will be the excess of (a) the
sum of (i) the amount of cash received and (ii) the fair market value of the
shares of BancGroup common stock received, over (b) the tax basis of the shares
of Bank stock exchanged therefore.  No loss shall be recognized.  Sections
356(a)(1), (c).

         (4)     Any gain recognized by a shareholder of the Bank will be
characterized as a capital gain if the Bank stock is a capital asset in the
hands of such shareholder and the receipt of the cash does not have "the effect
of the distribution of a dividend" within the meaning of Section 356 (a)(2) of
the Code as interpreted by the United States Supreme Court in Commissioner v.
Clark, 489 U.S. 726 (1989).  Pursuant to Clark, it will be assumed that
BancGroup issued all stock to each of the Bank shareholders and then BancGroup
redeemed a portion of such stock for the amount of cash that was actually
issued.  If that hypothetical redemption satisfies any of the tests of Section
302(b) of the Code, the hypothetical redemption will be treated as an exchange.
Otherwise, the receipt of the cash will be treated as a dividend under Section
356(a)(2) of the Code.  In the present case, the Bank shareholders should be
able to satisfy one or more of the tests of Section 302(b) of the Code.
However, the application of such provisions is dependent upon each
shareholders' facts and circumstances and is affected by the attribution rules
of Section 318 of the Code.  Consequently, shareholders should seek independent
tax advice as to the tax effect of the Merger, including the receipt of the
cash, to them.

         (5)     A dissenting Bank shareholder, who is not deemed to own any
shares of BancGroup under the constructive ownership rules of Section 318 of
the Code (see the discussion below of Section 318 of the Code), and who
receives only cash in exchange for his shares of Bank stock, will recognize
gain or loss equal to the difference between the amount of cash received and
the shareholder's basis in the shares of Bank stock surrendered.  Section 1001
of the Code.  Such gain or loss will be capital gain or loss if the shares are
capital assets in the hands of the shareholder.

         (6)     The constructive ownership rules of Section 318 of the Code
apply in determining whether the receipt of cash has "the effect of the
distribution of a dividend" and whether a dissenting Bank shareholder who
actually has received all cash is deemed to have received a combination of cash
and BancGroup common stock.  Under these rules, shares subject to options and
shares owned (or, in some cases, constructively owned) by members of the
shareholder's family, and by related entities (such as corporations,
partnerships,
<PAGE>   4
February 8, 1996
Page 4

trusts, and estates) in which the shareholder, a member of his family, or a
related entity has an interest may be counted as owned by the shareholder.
Similarly, an entity may be treated as owning shares owned by related persons
or entities (such as shareholders, partners, or beneficiaries).

         (7)     The tax basis of the BancGroup common stock received by a Bank
shareholder will be the same as the adjusted tax basis of the shares of Bank
stock exchanged, decreased by the amount of cash received and increased by the
amount treated as a dividend and the amount of gain recognized on the exchange.
Section 358(a)(1) of the Code.

         (8)     The holding period of the BancGroup common stock received by a
Bank shareholder will include the holding period of the shares of Bank stock
exchanged therefor if such shares were capital assets in the hands of the
exchanging shareholder.  Section 1223(1) of the Code.

         (9)     Cash received in lieu of a fractional share interest in
BancGroup common stock will be treated as received in payment for such
interest.  Rev. Rul. 66-365, 1966 - 2 C.B. 116.  The shareholder will recognize
gain or loss equal to the difference between the cash received and the basis of
such fractional share interest.

         (10)    Payment of cash for fractional shares should not effect the
classification of the Merger as a reorganization under Section 368(a) of the
Code, even though the total amount of cash paid in the Merger may exceed 50% of
the total consideration paid.  Though the IRS specifies for advance ruling
purposes that no more than 50% of the total consideration may consist of cash
or property other than the acquiring corporation's stock, that position is not
a rule of substantive law and courts have held that Merger transactions
qualified as reorganizations with cash and non-stock payments of greater than
50%.  In the present case, the total cash consideration should be only slightly
greater than 50% of the total consideration and the merger should not fail to
qualify as a reorganization under Section 368(a) of the Code as a result of
cash payments to holders of fractional shares.

                                    Very truly yours,



                                    /s/ MILLER, HAMILTON, SNIDER & ODOM, L.L.C.

<PAGE>   9

                 (b)      The Interest Rate set forth in a) (i) and (iii)
above, shall be selected by the Company for thirty (30) day Interest Periods

                 (d)      The Company shall give the Bank notice (in writing or
by telephone confirmed in writing) of the selection of the applicable Interest
Rate at least five (5) Banking Days prior to the end of the next preceding
Interest Period.  If the Company does not so provide notice to the Bank of the
selection of any Interest Rate, then the Company's selection for the
immediately preceding Interest Period shall carry over until changed by the
Company in accordance with the procedure contained in this Article 2.2.

                 (e)      Each Interest Period shall commence on the Day on
which the next preceding Interest Period expires unless any Interest Period
would otherwise expire on a Day which is not a Banking Day, in which event it
shall be extended to expire on the next succeeding Banking Day; provided, that
if any Interest Period would otherwise expire on a Day which is not a Banking
Day, but is a day of the month after which no further Banking Day occurs in
that month, that Interest Period shall expire on the next preceding Banking
Day.  Any Interest Period which begins on the last Banking Day of a calendar
month (or on a day for which there is no numerically corresponding day on the
calendar month at the end of such Interest Period) shall end on the last
Banking Day of a calendar month.

                 (f)      As soon as practicable after 11:00 a.m. (Orlando,
Florida time) on each Interest Rate Determination Date, the Bank shall
determine (which determination shall, absent manifest error, be final,
conclusive and binding upon all parties) the Interest Rate which shall apply
for the next succeeding Interest Period and shall promptly give notice thereof
(in writing or by telephone confirmed in writing) to the Company.

         From and after the Due Date, interest shall accrue on the unpaid
principal balance of the Loan and on all accrued but unpaid interest thereon,
or on such defaulted payment, from the Due Date at the Default Rate.  Such
interest shall continue to accrue until the date of payment in full of all
principal and accrued but unpaid interest of such defaulted payment, if
applicable.

         SECTION 2.3      Prepayment of the Loan.  The Company may prepay all
or any part of the principal amount of the Loan outstanding; provided, however,
that each permitted partial prepayment shall be applied to the reduction of the
Loan, in such manner as the Bank may, in its sole discretion, elect and,
further provided, that on the date of the prepayment, there shall exist no
Default and all





                                       9
<PAGE>   10

accrued but unpaid interest on the amount of the prepayment through the
prepayment date, whether or not due and payable, shall be paid in full prior to
any prepayment.  Each prepayment other than full payment shall be made prior to
2:00 p.m.  (Orlando time) on the date of the prepayment, and shall be made on a
Banking Day in immediately available funds.  Any prepayment made by the Company
shall be applied to amounts due under the Loan in such manner as the Bank may
designate in its absolute discretion.

         SECTION 2.4      Calculation of Interest.  Any interest due on the
Loan or any other Obligations shall be calculated on the basis of a year
containing 365 Days.  The interest due on any date for payment of interest
hereunder shall be that interest to the extent accrued as of midnight on the
last Day immediately prior to that interest payment date.  Notwithstanding
anything herein or in any Loan Document to the contrary, the sum of all
interest and all other amounts deemed interest under Florida or other
applicable law which may be collected by the Bank hereunder shall not exceed
the maximum lawful interest rate permitted by such law from time to time.  The
Bank and the Company intend and agree that under no circumstance shall the
Company be required to pay interest on the Loan or on any other Obligations at
a rate in excess of the maximum interest rate permitted by applicable law from
time to time, and in the event any such interest is received or charged by the
Bank in excess of that rate, the Company shall be entitled to an immediate
refund of any such excess interest by a credit to and payment toward the unpaid
balance of the Loan (such credit to be considered to have been made at the time
of the payment of the excess interest) with any excess interest not so credited
to be immediately paid to the Company by the Bank.

         SECTION 2.5      Place of Payment.  All payments by the Company under
the Loan Documents shall be made to the Bank at its banking house at Orlando,
Florida, in lawful money of the United States of America and in immediately
available funds.

         SECTION 2.6      Set-Off.  The Company hereby grants to the Bank a
lien on, and a security interest in, the deposit balances, accounts, items,
certificates of deposit and monies of the Company in the possession of or on
deposit with the Bank to secure and as collateral for the payment and
performance of the Obligations.  Upon default, the Bank may at any time and
from time to time, without demand or notice, appropriate and set-off against
and apply the same to the Obligations when and as due and payable.

         SECTION 2.7      Payment of Note.  The Company shall pay the Note 
together with interest at the rate determined in accordance with Section 2.2 
as follows:

                 (a)      Interest on the unpaid principal amount of the Note
shall be payable quarterly on the last Day of each quarter during the term of
this Agreement, commencing September 30, 1995 and





                                       10
<PAGE>   11

continuing on the same Day of each and every succeeding quarter during the term
hereof until the Maturity Date.

                 (b)      The outstanding principal balance of the Loan,
together with all accrued but unpaid interest, shall be payable in full on the
Maturity Date.

         SECTION 2.8      Application of Payments.  All payments made on the
Note shall be applied first to interest accrued to the date of payment and next
to the unpaid principal balance; provided, however, in the event an Event of
Default occurs, payments shall be applied first to any costs or expenses,
including attorneys fees, that the Bank may incur in exercising its rights
under the Loan Documents, as the Bank may determine.

properties and assets and to carry on its business as now conducted and

Pledge Agreement and the other Loan Documents.

                 (b)      Each Subsidiary (i) is a duly organized, validly

provisions contained in this Agreement, the Note or the other Loan Documents
shall for any reason be held to be invalid, illegal or unenforceable in any
respect, the same shall not affect any other provision of this Agreement, the

Loan Documents shall be construed as if such invalid or illegal or
unenforceable provision had never been contained therein; provided, however, in
the event said matter would in the reasonable opinion of the Bank adversely
effect the rights of the Bank under any or all of the Loan Documents, the same
shall be an Event of Default.

         SECTION 8.12     Cross Defaults.  A default under any Loan Document,
including a default under this Agreement, shall be and constitute a default
under each and every Loan Document, including this Agreement.  A default under

execution, delivery and performance of this Agreement or the execution,

in this Agreement contained by or on behalf of either of the parties hereto
shall bind and inure to the benefit of the respective successors and assigns of

                                       24
<PAGE>   25
other assignment which may be prohibited by the terms and conditions of this
Agreement.

                          AGREEMENT AND PLAN OF MERGER


         THIS AGREEMENT AND PLAN OF MERGER is made and entered into and is
effective as of the 21st  day of December, 1995 (the "Agreement"), by and among
The Colonial BancGroup, Inc., a Delaware corporation ("Acquiror"), and
Commercial Bancorp of Georgia, Inc., a Georgia corporation ("CBG").  Certain
capitalized terms used herein shall have the meanings ascribed to such terms in
Appendix A hereto.


                              W I T N E S S E T H:

         WHEREAS, Acquiror owns all of the issued and outstanding shares of
capital stock of Colonial Bank; and


         WHEREAS, CBG is a one-bank holding company that owns all of the issued
and outstanding capital stock of Commercial Bank; and

         WHEREAS, the Boards of Directors of Acquiror, and CBG have approved
the merger of CBG  with and into Acquiror (the "Merger") upon the terms and
subject to the conditions set forth herein;

         NOW, THEREFORE, in consideration of the mutual representations,
warranties, covenants and agreements, and upon and subject to the terms and the
conditions hereinafter set forth, the parties do hereby agree as follows:


                                   ARTICLE I

                                   THE MERGER

         1.01    The Merger.  Upon the terms and subject to the conditions of
this Agreement and in accordance with applicable law, at the Effective Time (as
defined in Section 1.02 below) CBG shall be merged with and into Acquiror and
the separate existence of CBG shall thereupon cease.  Acquiror shall be the
surviving corporation in the Merger (hereinafter sometimes referred to as the
"Surviving Corporation") and the name of the Surviving Corporation shall be
"The Colonial BancGroup, Inc."  As a result of the Merger, Commercial Bank will
become a wholly-owned subsidiary of Acquiror.

         1.02    Effective Time of the Merger.  The Merger shall become
effective at the time (the "Effective Time") specified in the  Certificate of
Merger to be issued by the Secretary of State of the State of Delaware.  The
filing of the Certificate of Merger shall be made simultaneously with or as
soon as possible following the closing of the transactions contemplated by this
Agreement in accordance with Article XII hereof.  It is the intent of the
parties hereto that the Effective Time shall be within five business days from
the date of the last required approval and the expiration of any applicable
waiting periods or as soon
<PAGE>   2

as practicable thereafter.

         1.03    Further Acts.  If, at any time after the Effective Time, the
Surviving 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 Surviving Corporation, title to and
possession of any property or right of CBG or Acquiror, acquired as a result of
the Merger, or (ii) otherwise to carry out the purposes of this Agreement, CBG
or Acquiror and its officers and directors shall execute and deliver all such
proper deeds, assignments and assurances in law and do all reasonable acts
necessary or proper to vest, perfect or confirm title to, and possession of,
such property or rights in the Surviving Corporation  and otherwise to carry
out the purposes of this Agreement; and the proper officers and directors of
the Surviving Corporation are fully authorized in the name of CBG or Acquiror,
or otherwise, to take any and all such action.


                                   ARTICLE II

                           THE SURVIVING CORPORATION

         2.01    Articles of Incorporation.  The Certificate of Incorporation
of Acquiror in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation after the Effective
Time until otherwise amended or repealed.

         2.02    Bylaws.  The Bylaws of Acquiror in effect immediately prior to
the Effective Time, shall be the Bylaws of the Surviving Corporation after the
Effective Time until otherwise amended or repealed.

         2.03    Directors and Officers of the Surviving Corporation.  The
directors of Acquiror in office immediately prior to the Effective Time shall
serve as the directors of the Surviving Corporation following the Effective
Time.  The officers of Acquiror in office immediately prior to the Effective
Time shall serve as the officers of the Surviving Corporation following the
Effective Time.


                                  ARTICLE III

                              CONVERSION OF SHARES

         3.01    Conversion of Shares.  Subject to the provisions of this
Article III, at the Effective Time, by virtue of the Merger and without any
action on the part of Acquiror, Colonial Bank, CBG, Commercial Bank, or the
stockholders of any of the foregoing, the shares of the constituent
corporations shall be converted as follows:

                 (a)      Each share of capital stock of Acquiror (the
"Acquiror Capital Stock"), including the Common Stock, $2.50 par value per
share of Acquiror ("Acquiror Common Stock"), and any associated rights to
acquire Acquiror Capital Stock, issued and outstanding immediately prior to the
Effective Time shall remain issued and outstanding from and after the Effective
Time.
<PAGE>   3

                 (b)      Each share of Common Stock of Colonial Bank issued
and outstanding immediately prior to the Effective Time shall remain issued and
outstanding from and after the Effective Time.

                 (c)      Each share of Common Stock, $1.00 par value per
share, of CBG ("CGB Common Stock") issued and outstanding at the Effective Time
(other than treasury stock or shares held by Acquiror which shares shall be
canceled) shall cease to be outstanding and shall, by virtue of the Merger and
without any action on the part of the holder thereof, be converted into and
exchanged for the right to receive the number of shares of Acquiror Common
Stock equal to $21.07 divided by the Market Value (subject to appropriate
adjustment in the event of a stock split, stock dividend or recapitalization or
other similar event applicable to shares of Acquiror Common Stock prior to the
Effective Time) (the "Exchange Ratio") upon surrender of the certificate
representing such shares of CBG Common Stock.  The Market Value shall represent
the per share market value of the Acquiror Common Stock at the Effective Time
and shall be equal to the average of the Daily Average Value (as defined below)
of the Acquiror Common Stock as reported by The New York Stock Exchange
("NYSE") on the thirty (30) trading days ending on the trading day immediately
preceding the Effective Time.  The Daily Average Value on each trading day
shall be the average of the high and low sales price of the Acquiror Common
Stock for such trading day as reported by the NYSE.

                 (d)      Each share of Common Stock of Commercial Bank issued
and outstanding immediately prior to the Effective Time shall remain issued and
outstanding from and after the Effective Time and shall be wholly owned by the
Surviving Corporation.

         3.02    Anti-Dilution Provisions.  In the event Acquiror changes the
number of shares of Acquiror Common Stock issued and outstanding prior to the
Effective Time as a result of a stock split, stock dividend, or similar
recapitalization with respect to such stock and the record date therefor (in
the case of a stock dividend) or the effective date thereof (in the case of a
stock split or similar recapitalization for which a record date is not
established) shall be prior to the Effective Time, the Market Value and, as a
result, the Exchange Ratio shall be proportionately adjusted to reflect such
stock split, stock dividend or other recapitalization.

         3.03    Fractional Shares.  Notwithstanding any other provision of
this Agreement, each holder of shares of CBG Common Stock exchanged pursuant to
the Merger who would otherwise have been entitled to receive a fraction of a
share of Acquiror Common Stock (after taking into account all certificates
delivered by such holder) shall receive, in lieu thereof, cash (without
interest) in an amount equal to such fractional part of a share of Acquiror
Common Stock multiplied by the Market Value.  No such holder will be entitled
to dividends, voting rights, or any other rights as a stockholder in respect of
any fractional shares.

         3.04    Conversion of Stock Options, Warrants and Stock Appreciation
Rights.

                 (a)       At the Effective Time, all rights with respect to
CBG Common Stock pursuant to stock options, stock purchase warrants or similar
rights, including rights under  contracts with employees of Commercial Bank
(collectively, "CBG Options"), granted by
<PAGE>   4

CBG or Commercial Bank, which are outstanding at the Effective Time, whether or
not exercisable, shall be converted into and become rights with respect to
Acquiror Common Stock, and Acquiror shall assume each CBG Option, in accordance
with the terms of the agreement or plan by which it is evidenced, except that
from and after the Effective Time, (i) each CBG Option assumed by Acquiror may
be exercised solely for shares of Acquiror Common Stock, (ii) the number of
shares of Acquiror Common Stock subject to such CBG Option shall be equal to
the number of shares of CBG Common Stock subject to such CBG Option immediately
prior to the Effective Time multiplied by the Exchange Ratio, and (iii) the per
share exercise price under each such CBG Option shall be adjusted by dividing
the per share exercise price under each such CBG Option by the Exchange Ratio
and rounding up to the nearest cent.  Notwithstanding the provisions of clause
(ii) of the preceding sentence, Acquiror shall not be obligated to issue any
fraction of a share of Acquiror Common Stock upon exercise of CBG Options and
any fraction of a share of Acquiror Common Stock that otherwise would be issued
upon the exercise of a converted CBG Option shall represent the right to
receive a cash payment upon exercise of such converted CBG Option equal to the
product of such fraction and the difference between the market value of one
share of Acquiror Common Stock at the time of exercise of such Option and the
per share exercise price of such CBG Option as adjusted pursuant to clause
(iii) of the preceding sentence.  The market value of one share of Acquiror
Common Stock at the time of exercise of a CBG Option shall be the last sale
price of such common stock on the NYSE (as reported by The Wall Street Journal
or, if not reported thereby, any other authoritative source selected by
Acquiror) on the last trading day preceding the date of exercise.  As soon as
practicable after the Effective Time, Acquiror shall file a registration
statement on Form S-3 or Form S-8, as the case may be (or any successor or
other appropriate forms), with respect to the shares of Acquiror Common Stock
subject to such options and shall use its reasonable best efforts to maintain
the effectiveness of such registration statement (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
CBG Options remain outstanding.  Schedule 3.04(a) lists the names of all
persons holding CBG Options, the number of shares of CBG Common Stock issuable
upon exercise of such CBG Options and the per share exercise price of such CBG
Options.

                 As soon as practicable after the Effective Time, Acquiror
shall deliver to the holders of each CBG Option an appropriate notice setting
forth such holder's rights pursuant to such CBG Option following the Merger.
At or prior to the Effective Time, Acquiror shall take all corporate action
necessary to reserve for issuance sufficient shares of Acquiror Common Stock
for delivery upon the exercise of CBG Options assumed by it in accordance with
this Section 3.04.

                 (b)      At the Effective Time, all obligations of CBG or
Commercial Bank under stock appreciation rights or similar rights, including
rights under the Commercial Bancorp of Georgia, Inc. and Commercial Bank of
Georgia Deferred Compensation Plan for Directors, as amended, the Commercial
Bancorp of Georgia, Inc., Commercial Bank of Georgia and Commercial Bank of
Gwinnett 1995 Deferred Compensation Plan for Directors (such plans are referred
to herein collectively as the "Deferred Compensation Plans") and under
contracts with employees of CBG or Commercial Bank (such stock appreciation
rights and similar rights are referred to as "CBG Stock Appreciation Rights"),
granted by
<PAGE>   5

CBG or Commercial Bank shall be assumed by Acquiror.  Within ten (10) days
following the Effective Time, Acquiror shall pay to each holder of CBG Stock
Appreciation Rights cash equal to the value of such holder's CBG Stock
Appreciation Right(s) determined in accordance with the terms of the plan or
agreement under which such rights were granted except that, solely for purposes
of determining the amount of cash to be paid to participants in the Deferred
Compensation Plans, each Stock Unit (as defined in the respective Deferred
Compensation Plan) credited to a participant's account under the Deferred
Compensation Plans shall be deemed to have a value of $21.07 without regard to
the fair market value of the CBG Common Stock on the immediately preceding
Valuation Date (as defined in the Deferred Compensation Plans).  Schedule
3.04(b) sets forth the names of all persons holding CBG Stock Appreciation
Rights, the number of units of stock appreciation rights and the current method
of determining the value of such stock appreciation rights.

         3.05    Exchange Procedures.  Promptly after the Effective Time,
Acquiror shall cause the exchange agent selected by Acquiror (the "Exchange
Agent") to mail to the former stockholders of CBG appropriate transmittal
materials.  After the Effective Time, each holder of shares of CBG Common Stock
issued and outstanding at the Effective Time shall surrender the certificate or
certificates representing such shares to the Exchange Agent and shall promptly
upon surrender thereof receive in exchange therefor the consideration provided
in Section 3.01 of this Agreement, together with all undelivered dividends or
distributions in respect of such shares (without interest thereon) pursuant to
Section 3.06 of this Agreement.  To the extent required by Section 3.03 of this
Agreement, each holder of shares of CBG Common Stock issued and outstanding at
the Effective Time also shall receive, upon surrender of the certificate or
certificates representing such shares, cash in lieu of any fractional share of
Acquiror Common Stock to which such holder may be otherwise entitled (without
interest).  Acquiror shall not be obligated to deliver the consideration to
which any former holder of CBG Common Stock is entitled as a result of the
Merger until such holder surrenders such holder's certificate or certificates
representing the shares of CBG Common Stock for exchange as provided in this
Section 3.05.  The certificate or certificates of CBG Common Stock so
surrendered shall be duly endorsed as the Exchange Agent may require.  Any
other provision of this Agreement notwithstanding, neither Acquiror, the
Surviving Corporation nor the Exchange Agent shall be liable to a holder of CBG
Common Stock for any amounts paid or property delivered in good faith to a
public official pursuant to any applicable abandoned property law.

         3.06    Rights of Former CBG Stockholders.  At the Effective Time, the
stock transfer books of CBG shall be closed as to holders of CBG Common Stock
immediately prior to the Effective Time and no transfer of CBG Common Stock by
any such holder shall thereafter be made or recognized.  Until surrendered for
exchange in accordance with the provisions of Section 3.05 of this Agreement,
each certificate theretofore representing shares of CBG Common Stock shall from
and after the Effective Time represent for all purposes only the right to
receive the consideration provided in Sections 3.01 and 3.03 of this Agreement
in exchange therefor.  Whenever a dividend or other distribution is declared by
Acquiror on the Acquiror Common Stock, the record date for which is at or after
the Effective Time, the declaration shall include dividends or other
distributions on all shares issuable pursuant to this Agreement, but beginning
60 days after the Effective Time no
<PAGE>   6

dividend or other distribution payable to the holders of record of Acquiror
Common Stock as of any time subsequent to the Effective Time shall be delivered
to the holder of any certificate representing shares of CBG Common Stock issued
and outstanding at the Effective Time until such holder surrenders such
certificate for exchange as provided in Section 3.05 of this Agreement.
However, upon surrender of such CBG Common Stock certificate, both the Acquiror
Common Stock certificate (together with all such undelivered dividends or other
distributions without interest) and any undelivered dividends and cash payments
to be paid for fractional share interests (without interest) shall be delivered
and paid with respect to each share represented by such certificate.

         3.07    Dissenters' Rights.  Notwithstanding Section 3.01, no
outstanding share of CBG Common Stock shall be converted into or represent a
right to receive any shares of Acquiror Common Stock pursuant to Section 3.01
if the holder thereof has demanded and perfected his demand for payment of the
fair value of such share in accordance with the applicable provisions of
Article 13 of the Georgia Business Corporation Code (the "Dissenter
Provisions") and has not effectively withdrawn or lost his right to such
payment.  All such shares of CBG Common Stock shall represent only the rights
granted with respect to such shares pursuant to the Dissenter Provisions.  CBG
shall give notice to Acquiror upon receipt by CBG of any written demands for
payment of the fair value of CBG Common Stock and of withdrawals of such
demands and any other written communications provided in accordance with or
pursuant to the Dissenter Provisions (any stockholder duly making such a demand
being hereinafter called a "Dissenting Stockholder").  Acquiror shall have the
right to participate in all negotiations and proceedings with respect to any
Dissenting Stockholder.  CBG agrees that it will not, except with the prior
consent of Acquiror, make any determination of fair value or any payment with
respect to, or settle or offer to settle any matter arising out of, any
dissent.  Each Dissenting Stockholder, if any, who becomes entitled to payment
for his shares of CBG Common Stock pursuant to the Dissenter Provisions shall
receive payment therefor from Acquiror (but only after the amount thereof shall
have been agreed upon or finally determined pursuant to the Dissenter
Provisions) and such dissenting shares of CBG Common Stock shall be canceled.
If any holder of shares of CBG Common Stock who demands payment of the fair
value of his shares under the Dissenter Provisions shall effectively withdraw
or lose (through failure to perfect or otherwise) his right to such payment at
any time, the shares of CBG Common Stock of such holder shall be converted into
a right to receive the consideration set forth in Section 3.01 hereof.


                                   ARTICLE IV

                     REPRESENTATIONS AND WARRANTIES OF CBG


         CBG represents and warrants to Acquiror as follows:

         4.01    Organization.  CBG is a corporation validly existing and in
good standing under the laws of the State of Georgia.  CBG has all requisite
corporate power and authority to
<PAGE>   7

carry on and conduct its business as now being conducted and to own, lease or
operate its material properties and assets.  CBG is duly qualified as a foreign
corporation, and is in good standing, in each state and foreign jurisdiction
where the character of its assets or the nature or conduct of its business
requires it to be so qualified except for such states and jurisdictions in
which the failure to be so qualified will not have a Material Adverse Effect on
CBG.

         4.02    Power and Authority.  CBG has the corporate power and
authority necessary to execute, deliver and perform its obligations under this
Agreement and to consummate the transactions contemplated hereby.  The
execution, delivery and performance of this Agreement, and the consummation of
the transactions contemplated hereby, have been duly and validly authorized by
all necessary corporate action on the part of CBG (subject to receipt of
appropriate approval by the stockholders of CBG).  Subject to such stockholder
approval, this Agreement constitutes CBG's legal, valid and binding obligation,
enforceable against CBG in accordance with its terms.

         4.03    Capitalization.

                 (a)      The authorized capital stock of CBG consists of (i)

                            COVENANTS OF THE PARTIES

         Acquiror and CBG hereby covenant to and agree with one another as
follows:

         8.01    Approvals of Third Parties; Satisfaction of Conditions to
Closing.   Acquiror, Colonial Bank, CBG and Commercial Bank  will use their
reasonable efforts, and will cooperate with one another, to secure all
necessary consents, approvals, authorizations and exemptions from governmental
agencies and other third parties, including, without limitation, all consents
required by Sections 9.05 and 9.06 hereof.  In connection therewith, Acquiror
shall promptly prepare and file applications with all regulatory authorities
having jurisdiction over the transactions contemplated by this Agreement
seeking the requisite consents and approvals to such transactions.  Acquiror,
Colonial Bank, CBG and Commercial Bank will use their reasonable, good faith
efforts to cause or obtain the satisfaction of the conditions specified in

file the Registration Statement on or before February 9, 1995 (or such later
date as is mutually agreed by the parties hereto) and to have the Registration
Statement declared effective under the Securities Act as promptly as
practicable after such filing.  Acquiror shall also take any action (other than
qualifying to do business in any jurisdiction in which it is now not so
qualified) required to be taken under any applicable state securities laws in
connection with the issuance of the Acquiror Common Stock in the Merger.

         8.03    Confidentiality.  In connection with this Agreement, the
parties may have access to information which is nonpublic, confidential or
proprietary in nature.  All of such information, in whole or in part, together
with any analyses, compilations, studies or other documents prepared by any
party, which contain or otherwise reflect any such information is hereinafter
referred to as the "Information".  Each party hereby agrees that the
Information will be kept confidential and shall not, without the prior mutual
written consent of the parties, be disclosed, in any manner whatsoever, in
whole or in part, and shall not be used by any party following the termination
of this Agreement.  Each party agrees to transmit the Information only to its
respective employees and representatives who need to know the Information and
who shall agree to be bound by the terms and conditions of this Agreement.  In
any event, each party shall be responsible for any breach of this Agreement by
its respective employees or representatives.  If the transactions contemplated
hereunder are not consummated, the parties shall return the Information to the
other promptly upon request and no party shall retain any copies.   In the
event any party becomes legally compelled to disclose any of the Information,

party may seek a protective order or other appropriate remedy and/or waive
compliance with the provisions of this Agreement.  In the event that such
protective order or other remedy is not obtained, or compliance with the
provisions of this Agreement is waived, a party will furnish only that portion
of the Information which

exercise its best efforts to obtain a protective order or other reliable
assurance that confidential treatment will be accorded the Information.  The
term "Information" does not include information which (i)  was known to any
party about another party prior to its disclosure, provided that such
information was  lawfully obtained or developed, (ii) becomes generally
available to the public other than as a result of a disclosure by a party in
violation of this Agreement, or (iii) becomes available from a source other
than a party to this Agreement, if the source is not bound by a confidentiality
agreement and such source lawfully obtained such information.

         8.04    Press Releases.  Prior to the Effective Time, CBG and Acquiror
shall consult with each other as to the form and substance of any press release
or other public disclosure related to this Agreement or to transactions
contemplated hereby; provided that nothing in this Section 8.04 shall be deemed
to prohibit any party hereto from making any disclosure which its counsel deems
necessary or advisable in order to satisfy such party's disclosure obligations
imposed by law.

will be equal to the sum of the tax basis of their shares of CBG Common Stock

the exchanging CBG shareholder, including any portion treated as a dividend,
less the value of taxable boot, if any, received by such shareholder in the

fractional share interest of Acquiror Common Stock will be treated as having
been received as a distribution in full payment in exchange for the fractional
share interest of Acquiror Common Stock which he would otherwise be entitled to
receive and will qualify as capital gain or loss (assuming the CBG Common Stock
was a capital asset in his hands as of the Effective Time).

of assets of CBG or Commercial Bank (collectively, a "Business Combination");
except in a situation in which a majority of the full Board of Directors of CBG
has determined upon advice of counsel that such Board has a fiduciary duty to
consider and respond to a bona fide proposal by a third party, regardless of
whether such proposal was directly or indirectly received as a result of
conduct sought to be prohibited by this Section 15.10.  Upon the occurrence of
such determination by the Board of Directors of CBG, such Board shall provide
written notice of its determination and intention to consider such proposal to
Acquiror at least two business days before responding to the proposal or
providing any information with respect to CBG or Commercial Bank  in response
to the proposal, indicating the material terms of such proposal; provided,
however, that if such proposal by its terms requires a response in a shorter
period, CBG shall provide such notice, information and undertaking to Acquiror
as promptly as practicable in the circumstances.  Notwithstanding the
foregoing, nothing in this Section 15.10 relating to fiduciary duties shall
preclude an action by Acquiror against CBG for breach by CBG of any other
provision of this Agreement provided that this sentence shall not confir upon
Acquiror any additional rights other than such rights as it otherwise would
have pursuant to such other provisions of this Agreement.

         15.11   No Third-Party Beneficiaries.  With the exception of the
parties to this Agreement and the Indemnified Parties, there shall exist no
right of any person to claim a beneficial interest in this Agreement or any
rights occurring by virtue of this Agreement.

         15.12   "Including."  Words of inclusion shall not be construed as
terms of limitation herein, so that references to "included" matters shall be
regarded as non-exclusive, non-characterizing illustrations.

         15.13   Severability.  Any term or provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining terms and provisions thereof or affecting the
validity or enforceability of such provision in any other jurisdiction, and if
any term or provision of this Agreement is held by any court to be void,
voidable, invalid or unenforceable in any given circumstance or situation, then
all other terms and provisions, being severable, shall remain in full force and
effect in such circumstance or situation and the said term or provision shall
remain valid and in effect in any other circumstances or situation.

         15.14   Return of Information.  In the event of termination of this
Agreement prior to the Effective Time, each party shall return to the other,
without retaining copies thereof, all confidential or non-public documents,
work papers and other materials obtained from the other party in connection
with the transactions contemplated in this Agreement and shall keep such
information confidential, not disclose such information to any other person or
entity, and not use such information in connection with its business.

         15.15   Equitable Remedies.  The parties hereto agree that, in the
event of a breach of
<PAGE>   37

this Agreement by either party, the other party may be without an adequate
remedy at law owing to the unique nature of the contemplated transactions.  In
recognition thereof, in addition to (and not in lieu of) any remedies at law
that may be available to the non-breaching party, the non-breaching party shall
be entitled to obtain equitable relief, including the remedies of specific
performance and injunction, in the event of a breach of this Agreement by the
other party, and no attempt on the part of the non-breaching party to obtain
such equitable relief shall be deemed to constitute an election of remedies by
the non-breaching party that would preclude the non-breaching party from
obtaining any remedies at law to which it would otherwise be entitled.

         15.16   No Waiver.  No failure, delay or omission of or by any party
in exercising any right, power or remedy upon any breach or default of any
other party shall impair any such rights, powers or remedies of the party not
in breach or default, nor shall it be construed to be a waiver of any such
right, power or remedy, or an acquiescence in any similar breach or default;
nor shall any waiver of any single breach or default be deemed a waiver of any
other breach or default theretofore or thereafter occurring.  Any waiver,
permit, consent or approval of any kind or character on the part of any party
of any provisions of this Agreement must be in writing and be executed by the
parties to this Agreement and shall be effective only to the extent
specifically set forth in such writing.

         15.18   Remedies Cumulative.  All remedies provided in this Agreement,
by law or otherwise, shall be cumulative and not alternative.

         IN WITNESS WHEREOF, each of the parties hereto has caused this
Agreement to be duly executed on its behalf as of the date indicated on the
first page 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,

                          CONVERSION OF SOUTHERN STOCK

         3.1     CONVERSION OF SOUTHERN STOCK.  (a) On the Effective Date, and
subject to sections 3.3 and 3.6, each share of common stock of Southern
outstanding and held by Southern's shareholders (the "Southern Stock"), shall
be converted into .3919 of a share of BancGroup Common Stock (i.e., the
"Exchange Ratio").  Shares of Southern common stock that may be issued pursuant
to the exercise of options under Southern's stock option plans (the "Southern
Options") shall be converted as provided in section 3.1(b).

         (b)(i)    Southern shall cancel and exchange all Southern Options
outstanding at the Effective Date as to which, at least five days prior to the
Effective Date, the holders thereof have consented in writing to the
cancellation and conversion thereof.  In exchange therefor, Southern shall
distribute shares of BancGroup common stock as determined below.  BancGroup
shall issue such shares of BancGroup common stock to Southern for delivery to
the holders of Southern Options on the Effective Date.  Notwithstanding the
foregoing, Southern Options granted pursuant to the 1989 Employee Incentive
Stock Option Plan (the "ISOs") may not be exchanged for shares of BancGroup
common stock pursuant to this section but shall be converted into BancGroup
options pursuant to section 3.1(b)(ii).  The number of shares of BancGroup
Common Stock to be issued in exchange for the cancellation of the Southern
Options, excluding the ISOs, is set forth in the following table:

No fractions of shares of BancGroup Common Stock shall be issued and fractions
shall be exchanged for cash in accordance with section 3.3 hereof.  As of the
date hereof, the number of shares of common stock of Southern outstanding and
held of record is 3,362,000 and the number of shares subject to Southern
Options, including the ISOs, is 1,112,000.  Assuming no Southern Options are
exercised prior to the Effective Date, and all Southern Options other than the
ISOs are converted in accordance with this section 3.1(b)(i), the number of
shares of BancGroup Common Stock to be issued in the Merger shall be 1,605,235. 
Schedule 3.1(b) hereto sets forth the names of all persons holding Southern
Options, the number of shares of Southern common stock subject to such options
and the exercise price per share for such options.

         (b)(ii) On the Effective Date, BancGroup shall assume all Southern
Options outstanding as to which the holders thereof have not consented to the
cancellation and
<PAGE>   9

conversion thereof as provided by section 3.1(b)(i) and each such option shall
represent the right to acquire BancGroup Common Stock on substantially the same
terms applicable to the Southern 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 Southern common stock
subject to such Southern Options multiplied by .3919.  The exercise price for
the acquisition of BancGroup Common Stock shall be the exercise price for each
share of Southern common stock subject to such options divided by .3919.
Assuming that none of the holders of the Southern Options consent to the
cancellation and conversion thereof as provided by Section 3.1(b)(i), then the
Southern Options would be converted into BancGroup Options with the following

Notwithstanding the foregoing, no fractions of shares of BancGroup Common Stock
shall be issued upon exercise of such options and any fraction of a share of
BancGroup Common Stock that would otherwise be issued upon the exercise of such
options shall be converted into cash upon the exercise of such option in an
amount equal to the product of such fraction and the difference between the
market value of one share of BancGroup Common Stock at the time of exercise of
such option and the per share exercise price of such option.  The market value
of one share of BancGroup Common Stock at the time of exercise of such options
shall be the closing sales price of BancGroup Common Stock on the NYSE on the
last trading day preceding the date of exercise.  As soon as practicable after
the Effective Date, BancGroup shall file at its expense a registration
statement with the SEC on Form S-8 or other appropriate form with respect to
the shares of BancGroup Common Stock to be issued pursuant to such options and
shall use its reasonable best efforts to maintain the effectiveness of such
registration statement for so long as such options 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.
<PAGE>   10

         3.2     SURRENDER OF SOUTHERN STOCK.  After the Effective Date, each
holder of an outstanding certificate or certificates which prior thereto
represented shares of Southern Stock who is entitled to receive BancGroup
Common Stock shall be entitled, upon surrender to BancGroup of their
certificate or certificates representing shares of Southern Stock, 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
Southern 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 Southern
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 Southern 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 Southern 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 Southern Stock, be paid by  BancGroup an amount in cash
equal to the market value of such fractional share.  For this purpose, "market
value" shall mean the average of the closing prices of BancGroup Common Stock
on each of the 20 trading days ending on the trading day immediately prior to
the Effective Date as reported by the NYSE.

         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 Common Stock, an appropriate and proportionate adjustment shall be
made in the number of shares of BancGroup Common Stock into which the Southern
Stock and Southern Options shall be converted, and the market values stated in
section 8.6 hereof shall be appropriately adjusted.

         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.

         3.6     DISSENTING RIGHTS.  Any shareholder of Southern who shall 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
Southern Stock.  If after the Effective Date a dissenting shareholder of
Southern fails to perfect, or effectively withdraws or loses, his right to
appraisal and payment for his shares of Southern Stock, BancGroup shall issue
and deliver the consideration to which such holder of shares of Southern Stock
is entitled under Section 3.1 (without interest) upon surrender of such holder
of the certificate or certificates representing shares of Southern Stock held
by him.

                                  ARTICLE 4
           REPRESENTATIONS, WARRANTIES AND COVENANTS OF BANCGROUP

BancGroup represents, warrants and covenants to and with Southern 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
on the condition (financial or other), earnings, business, affairs, Assets,
properties, prospects or results of operations of BancGroup or of BancGroup and
its Subsidiaries taken as a whole.

         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 September 30, 1995, 12,267,143 shares were validly issued and outstanding,
fully paid and nonassessable and are not subject to preemptive rights, 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 Common Stock to be issued upon 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 Southern.

                 (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
Southern copies of the following financial statements of BancGroup.

                          (i)     Consolidated balance sheets as of December
31, 1993, and December 31, 1994, and for the nine months ending September 30,
1995;

                          (ii)    Consolidated statements of operations for
each of the three years ended December 31, 1992, 1993 and 1994, and for the
nine months ending September 30, 1995;

                          (iii)  Consolidated statements of cash flows for each
of the three years ended December 31, 1992, 1993 and 1994, and for the nine
months ending September 30, 1995; and
<PAGE>   12

                          (iv)    Consolidated statements of changes in
shareholders' equity for the three years ended December 31, 1992, 1993 and
1994, and for the nine months ending September 30, 1995.

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, other than Liabilities (including reserves) in the amount
set forth in such balance sheets and 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 BancGroup and its Subsidiaries for the periods indicated.  The
foregoing representations, insofar as they relate to the unaudited interim
financial statements of BancGroup for the nine months ended September 30, 1995,
are subject in all cases to normal recurring year-end adjustments and the
omission of footnote disclosure.

                 (b)      All Tax returns required to be filed by or on behalf
of BancGroup have been timely filed (or requests for extensions therefor have
been timely filed and granted and have not expired), and all returns filed are
complete and accurate in all material respects.  All Taxes shown on said
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 of BancGroup, sufficient in all material respects for the
payment of all unpaid federal, state, county, local, foreign or other Taxes
(including any interest or penalties) of BancGroup accrued for or applicable to
the period ended on the dates thereof, and all years and periods prior thereto
and for which BancGroup may at said dates have been liable in its own right or
as transferee of the Assets of, or as successor to, any other corporation or
other party.  No audit, examination or investigation is presently being
conducted or, to the Knowledge of BancGroup, threatened by any taxing authority
which is likely to result in a material Tax Liability, no material unpaid Tax
deficiencies or additional liabilities of any sort have been proposed by any
governmental representative and no agreements for extension of time for the
assessment of any material amount of Tax have been entered into by or on behalf
of BancGroup.  BancGroup has withheld from its employees (and timely paid to
the appropriate governmental entity) proper and accurate amounts for all
periods in material compliance with 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 indenture, mortgage, deed of trust or other material
agreement or instrument to which BancGroup or
<PAGE>   13

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 BancGroup or the articles of incorporation or bylaws
of any of its Subsidiaries; and will not violate any provision of any Law,
regulation, judgment or decree binding on them or any of their Assets.

         4.5     ABSENCE OF MATERIAL ADVERSE CHANGE.  Since the date of the
most recent balance sheet provided under section 4.3(a)(i) above, there have
been no events, changes or occurrences which have had or are reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on
BancGroup.

         4.6     APPROVAL OF AGREEMENTS.  The board of directors of BancGroup
has, or will have prior to the Effective Date, approved this Agreement and the
transactions contemplated by it and have, or will have prior to the Effective
Date, authorized the execution and delivery by BancGroup of this Agreement.
This Agreement constitutes the legal, valid and binding obligation of
BancGroup, enforceable against it in accordance with its terms.  Approval of
this Agreement by the stockholders of BancGroup is not required by applicable
law.  Subject to 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 contemplated by this Agreement.  BancGroup has no Knowledge of
any fact or circumstance under which the appropriate regulatory approvals
required by section 8.2 will not be granted without the imposition of material
conditions or material delays.

         4.7     TAX TREATMENT.  BancGroup has no present plan to sell or
otherwise dispose of any of the Assets of Southern, or to liquidate any
Subsidiaries, subsequent to the Merger, and BancGroup intends to continue the
historic business of Southern.

         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 Assets sold or otherwise disposed of since such date, in the
ordinary course of business), free and clear of all mortgages, Liens, pledges,
charges or encumbrances except (i) mortgages and other encumbrances referred to
in the notes of such balance sheet, (ii) liens for current Taxes not yet due
and payable and (iii) such imperfections of title and easements as do not
materially detract from or interfere with the present use of the properties
subject thereto or affected thereby, or otherwise materially impair present
business operations at such properties.  To the Knowledge of BancGroup, the
material structures and equipment of BancGroup comply in all material respects
with the requirements of all applicable Laws.

         4.9     SUBSIDIARIES.  Each Subsidiary of BancGroup has been duly
incorporated 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 conducts any business so as to require such qualification and in
which the failure to be duly qualified could have a Material Adverse Effect
upon
<PAGE>   14

BancGroup and its Subsidiaries considered as one enterprise; each of the
banking 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 to subsidiaries of registered bank holding companies.

         4.10    CONTRACTS.  Neither BancGroup nor any of its Subsidiaries is
in violation of its respective certificate of incorporation or by-laws or in
default in the performance or observance of any material obligation, agreement,
covenant or condition contained in any Contract, indenture, mortgage, loan
agreement, note, lease or other instrument to which it is a party or by which
it or its property may be bound.

         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 against or affecting BancGroup or any of its Subsidiaries (nor is
BancGroup aware of any facts which could give rise to any such Litigation)
which is required to be disclosed in the Registration Statement (other than as
disclosed therein), or which is likely to have any Material Adverse Effect or
prospective Material Adverse Effect in the condition, financial or otherwise,
or in the general affairs, management, stockholders' equity or results of
operations of BancGroup and its Subsidiaries considered as one enterprise, or
which is likely to materially and adversely affect the properties or Assets
thereof or which is likely to materially affect or delay the consummation of
the transactions contemplated by this Agreement; all pending 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 could be
considered material to BancGroup and its Subsidiaries considered as one
enterprise which are not disclosed in the Registration Statement as it may be
amended or supplemented.

         4.12    COMPLIANCE.  BancGroup and its Subsidiaries, in the conduct of
their businesses, are to the Knowledge of BancGroup, in material compliance
with all material federal, state or local Laws applicable to their or the
conduct of their businesses.

         4.13    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 a
part thereof, will comply in all material respects with the requirements of the
1933 Act and the rules and regulations thereunder, 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 subsection shall not apply to statements
in or omissions from the Proxy Statement made in reliance upon and in
conformity with information furnished in writing to BancGroup by Southern or
any of its representatives expressly for use in the Proxy
<PAGE>   15

                                  ARTICLE 5
            REPRESENTATIONS, WARRANTIES AND COVENANTS OF SOUTHERN

         Southern represents, warrants and covenants to and with BancGroup, as
follows:

         5.1     ORGANIZATION.  Southern is a Florida corporation, and the Bank
is a Florida banking corporation and not a member of the Federal Reserve
System.  Each Southern Company is duly organized, validly existing and in good
standing under the respective Laws of its jurisdiction of incorporation and has
all requisite power and authority to carry on its business as it is now being
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 on the
condition (financial or other) earnings, business, affairs, Assets, properties,
prospects or results of operations of Southern or of Southern and its
Subsidiaries taken as a whole.

         5.2     CAPITAL STOCK.  (i) As of September 30, 1995, the authorized
capital stock of Southern consists of 10,000,000 shares of common stock, $1.00
par value per share, 3,362,000 shares of which are issued and outstanding.  All
of such shares which are outstanding are validly issued, fully paid and
nonassessable and not subject to preemptive rights.  Southern has 1,112,000
shares of its common stock subject to exercise pursuant to stock options under
its stock option plans.  Except for the foregoing, Southern does not have any
other arrangements or commitments obligating it to issue shares of its capital
stock or any securities convertible into or having the right to purchase shares
of its capital stock.

         5.3     SUBSIDIARIES.  Southern has no direct Subsidiaries other than
the Bank, and there are no operating subsidiaries of the Bank.  Southern owns
all of the issued and outstanding capital stock of the Bank free and clear of
any liens, claims or encumbrances of any kind.  All of the issued and
outstanding shares of capital stock of the Subsidiaries have been validly
issued and are fully paid and non-assessable.  As of September 30, 1995, there
were 1,000,000 shares of the common stock, par value $4.00 per share,
authorized of the Bank, 527,778 of which are issued and outstanding and wholly
owned by Southern.

         5.4     FINANCIAL STATEMENTS; TAXES  (a)  Southern has delivered to
BancGroup copies of the following financial statements of Southern:
<PAGE>   17

                          (i)     Consolidated statements of financial
condition as of December 31, 1993 and 1994, and for the nine months ending
September 30, 1995;

                          (ii)    Consolidated statements of income for each of
the three years ended December 31, 1992, 1993 and 1994, and for the nine months
ending September 30, 1995;

                          (iii)   Consolidated statements of stockholders' 
equity for each of the three years ended December 31, 1992, 1993, and 1994,
and for the nine months ending September 30, 1995; and

                          (iv)    Consolidated statements of cash flows for the
three years ended December 31, 1992, 1993 and 1994, and for the nine months
ending September 30, 1995.

         All of the foregoing financial statements are in all material respects
in accordance with the books and records of Southern and have been prepared in
accordance with generally accepted accounting principles applied on a
consistent basis throughout the periods indicated, except for changes required
by GAAP, all as more particularly set forth in the notes to such statements.
Each of such balance sheets presents fairly as of its date the financial
condition of Southern.  Except as and to the extent reflected or reserved
against in such balance sheets (including the notes thereto), Southern did not
have, as of the date 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, other than Liabilities (including reserves)
in the amount set forth in such balance sheets and the notes thereto.  The
statements of income, stockholders' equity and cash flows present fairly the
results of operation, changes in shareholders equity and cash flows of Southern
for the periods indicated.  The foregoing representations, insofar as they
relate to the unaudited interim financial statements of Southern for the nine
months ended September 30, 1995, are subject in all cases to normal recurring
year-end adjustments and the omission of footnote disclosure.

                 (b)      Except as set forth on Schedule 5.4(b), all Tax
returns required to be filed by or on behalf of Southern have been timely filed
(or requests for extensions therefor have been timely filed and granted and
have not expired), and all returns filed are complete and accurate in all
material respects.  All Taxes shown on said returns to be due and all
additional assessments received have been paid.  The amounts recorded for Taxes
on the balance sheets provided under section 5.4(a) are, to the Knowledge of
Southern, sufficient in all material respects for the payment of all unpaid
federal, state, county, local, foreign and other Taxes (including any interest
or penalties) of Southern accrued for or applicable to the period ended on the
dates thereof, and all years and periods prior thereto and for which Southern
may at said dates have been liable in its own right or as a transferee of the
Assets of, or as successor to, any other corporation or other party. No audit,
examination or investigation is presently being conducted or, to the Knowledge
of Southern, threatened by any taxing authority which is likely to result in a
material Tax Liability, no material unpaid Tax deficiencies or additional
liability of any sort have been proposed by any governmental representative and
no agreements for extension of time for the assessment of any material amount
of Tax have been entered into by or on behalf of Southern.
<PAGE>   18

Southern has not executed an extension or waiver of any statute of limitations
on the assessment or collection of any Tax due that is currently in effect.

                 (c)      Each Southern Company has withheld from its employees
(and timely paid to the appropriate governmental entity) proper and accurate
amounts for all periods in material compliance with 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).  Each Southern Company is in compliance with, and
its records contain all information and documents (including properly completed
IRS Forms W-9) necessary to comply with, all applicable information reporting
and Tax withholding requirements under federal, state and local Tax Laws, and
such records identify with specificity all accounts subject to backup
withholding under section 3406 of the Code.

         5.5     ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth on
Schedule 5.5, since the date of the most recent balance sheet provided under
section 5.4(a)(i) above, no Southern Company has

                 (a)      issued, delivered or agreed to issue or deliver any

held in the treasury) except shares of common stock issued upon the exercise of
Southern Options and shares issued as director's qualifying shares;

                 (b)      borrowed or agreed to borrow any funds or incurred,
or become subject to, any Liability (absolute or contingent) except borrowings,

consistent with past practice;

                 (c)      paid any material obligation or Liability (absolute
or contingent) other than current Liabilities reflected in or shown on the most
recent balance sheet referred to in section 5.4(a)(i) and current Liabilities
incurred since that date in the ordinary course of business and consistent with
past practice;

                 (d)      declared or made, or agreed to declare or make, any
payment of dividends or distributions of any Assets of any kind whatsoever to
shareholders, or purchased or redeemed, or agreed to purchase or redeem, any of
its outstanding securities;

                 (e)      except in the ordinary course of business, sold or
transferred, or agreed to sell or transfer, any of its Assets, or canceled, or
agreed to cancel, any debts or claims;

                 (f)      except in the ordinary course of business, entered or
agreed to enter into any agreement or arrangement granting any preferential
rights to purchase any of its Assets, or requiring the consent of any party to
the transfer and assignment of any of its Assets;

                 (g)      suffered any Losses or waived any rights of value
which in either event in the aggregate are material considering its business as
a whole;
<PAGE>   19

                 (h)      except in the ordinary course of business, made or
permitted 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;

                 (i)      except in accordance with normal and usual practice,
made 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;

                 (j)      except in accordance with normal and usual practice,
increased the rate of compensation payable to or to become payable to any of
its officers or employees or made 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;

                 (k)      received notice or had Knowledge or reason to believe
that any of its substantial customers has terminated or intends to terminate
its relationship, which termination would have a Material Adverse Effect on its
financial condition, results of operations, business, Assets or properties;

                 (l)      failed 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;

than in the ordinary course of business; or

                 (n)      agreed in writing, or otherwise, to take any action
described in clauses (a) through (m) above.

         Between the date hereof and the Effective Date, no Southern Company,
without the express written approval of BancGroup, will do any of the things
listed in clauses (a) through (n) of this section 5.5 except as permitted
therein or as contemplated in this Agreement, and no Southern Company will
enter into or amend any material Contract without the express written consent
of BancGroup.  Southern may request the consent of BancGroup to any of the
foregoing actions by furnishing BancGroup with a written request which
describes the action proposed to be taken by Southern.  Such consent shall not
be unreasonably withheld.  BancGroup shall have a period of 10 days from the
date on which it receives such request within which to notify Southern of
either its consent or refusal to consent, to the proposed action.  BancGroup's
failure to respond to any such request within such 10 days period shall be
deemed to constitute a consent to the action proposed in Southern's request.

         5.6     TITLE AND RELATED MATTERS.

                 (a)      Title.  Southern has good and marketable title to all
the properties, interest in properties and Assets, real and personal, reflected
in the most recent balance
<PAGE>   20

sheet referred to in section 5.4(a)(i), or acquired after the date of such
balance sheet (except properties, interests and Assets sold or otherwise
disposed of since such date, in the ordinary course of business), free and
clear of all mortgages, Liens, pledges, charges or encumbrances except (i)
mortgages and other encumbrances referred to in the notes to such balance
sheet, (ii) Liens for current Taxes not yet due and payable and (iii) such
imperfections of title and easements as do not materially detract from or
interfere with the present use of the properties subject thereto or affected
thereby, or otherwise materially impair present business operations at such
properties.  To the Knowledge of Southern, the material structures and
equipment of each Southern Company comply in all material respects with the
requirements of all applicable Laws.

                 (b)      Leases.  Schedule 5.6(b) sets forth a list and

contains a description of all agreements relating to data processing computer

software unable to satisfactorily perform the tasks and functions to be
performed by them in the business of any Southern Company.

         5.7     COMMITMENTS.  Except as set forth in Schedule 5.7, no Southern
Company is a party to any oral or written (i) Contracts for the employment of
any officer or employee which is not terminable on 30 days' (or less) notice,

made available to BancGroup for inspection.

         5.8     CHARTER AND BYLAWS.  Schedule 5.8 contains true and correct
copies of the articles of incorporation and bylaws of each Southern Company,
including all amendments thereto, as currently in effect.  There will be no
changes in such articles of incorporation or bylaws prior to the Effective

         5.9     LITIGATION.  There is no Litigation (whether or not
purportedly on behalf of Southern) pending or, to the Knowledge of Southern,
threatened against or affecting any
<PAGE>   21

Southern Company (nor is Southern aware of any facts which are likely to give
rise to any such Litigation) at law or in equity, or before or by any
governmental 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 the business operations, properties or Assets or in the condition,
financial or otherwise, of any Southern Company, and no Southern 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 the business operations, properties or Assets or
in the condition, financial or otherwise, of such party.  To the Knowledge of
Southern, each Southern Company has complied in all material respects with all
material applicable Laws and Regulations including those imposing Taxes, or 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 in the business operations, properties or Assets or in the
condition, financial or otherwise, of any such Southern Company.

         5.10    MATERIAL CONTRACT DEFAULTS.  Except as disclosed on Schedule
5.10, no Southern 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
Southern, 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 Contract, indenture,
mortgage, deed of trust or other material agreement or instrument to which any
Southern Company is a party and will not conflict with any provision of the
charter or bylaws of any Southern Company.

         5.12    GOVERNMENTAL AUTHORIZATION.  Each Southern Company has all
Permits that, to the Knowledge of Southern, are or will be legally required to
enable any Southern Company to conduct its business in all material respects as
now conducted by each Southern Company.

         5.13    ABSENCE OF REGULATORY COMMUNICATIONS.  Except as provided in
Schedule 5.13, no Southern Company is subject to, nor has any Southern Company
received during the past three years, any written communication directed
specifically to it from any Agency to which it is subject or pursuant to which
such Agency has imposed or has indicated it may impose any 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.
<PAGE>   22


         5.14    ABSENCE OF MATERIAL ADVERSE CHANGE.  To the Knowledge of 
Southern, since the date of the most recent balance sheet provided under 
section 5.4(a)(i), there have been no events, changes or occurrences which 
have had, or are reasonably likely to have, individually or in the aggregate, 
a Material Adverse Effect on any Southern Company.

         5.15    INSURANCE.  Each Southern Company has in effect insurance
coverage and bonds with reputable insurers which, in respect to amounts, types
and risks insured, management of Southern reasonably believes to be adequate
for the type of business conducted by such company.  No Southern Company is
liable for any material retroactive premium adjustment.  All insurance policies
and bonds are valid, enforceable and in full force and effect, and no Southern
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 Southern 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 Southern Company at all times from the date
hereof to the Effective Date.

         5.16    PENSION AND EMPLOYEE BENEFIT PLANS.

                 (a)      To the Knowledge of Southern, all employee benefit
plans of each  Southern 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 Section 5.16, no Southern 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 Southern 401(k) plan 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 Southern, 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 Southern Company.

                 (b)      To the Knowledge of Southern, no amounts payable to
any employee of any Southern 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 Southern, 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 Southern, any similar
agreement or any voting agreement or voting trust in respect of any such
shares.
<PAGE>   23

         5.18    BROKERS.  Except for services provided for Southern by The
Carson Medlin Company, all negotiations relative to this Agreement and the
transactions contemplated by this Agreement have been carried on by Southern
directly with BancGroup and without the intervention of any other person,
either as a result of any act of Southern, or otherwise, in such manner as to
give rise to any valid claim against Southern for a finder's fee, brokerage
commission or other like payment.

         5.19    APPROVAL OF AGREEMENTS.  The board of directors of Southern
has approved this Agreement and the transactions contemplated by this Agreement
and has authorized the execution and delivery by Southern of this Agreement.
Subject to the matters referred to in section 8.2, Southern has full power,
authority and legal right to enter into this Agreement, and, upon appropriate
vote of the shareholders of Southern in accordance with this Agreement,
Southern shall have full power, authority and legal right to consummate the
transactions contemplated by this Agreement.

         5.20    DISCLOSURE.  No representation or warranty, nor any statement
or certificate furnished or to be furnished to BancGroup by Southern, 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 Southern, its Assets, properties,
operations, and capital stock or to information furnished in writing by
Southern or its 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
Southern have been calculated in accordance with prudent and customary banking
practices and are adequate to reflect the risk inherent in the loans of
Southern.  Southern 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 Southern 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.  Southern does not have in its
portfolio any loan exceeding its legal lending limit, and except as disclosed
on Schedule 5.22, Southern has no known significant delinquent, substandard,
doubtful, loss, nonperforming or problem loans.
<PAGE>   24

         5.23    ENVIRONMENTAL MATTERS.  Except as provided in Schedule 5.23,
to the Knowledge of Southern, each Southern 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 Southern has no Knowledge that
any  Southern Company has not complied with all regulations and requirements
promulgated by the Occupational Safety and Health Administration that are
applicable to any Southern Company.  To the Knowledge of Southern, there is no
Litigation pending or threatened with respect to any violation or alleged
violation of the Environmental Laws.  To the Knowledge of Southern, with
respect to Assets of or owned by any Southern Company, including any Loan
Property, (i) there has been no spillage, leakage, contamination or release of
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 Southern Company.  Southern has no
Knowledge of any facts which might suggest that any Southern 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 Southern 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 Southern, no
Southern 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.  Southern has no Knowledge of any plan or
intention on the part of Southern's shareholders to sell or otherwise dispose

fair market value of Southern common stock outstanding immediately before the
Merger.

         5.25    COLLECTIVE BARGAINING.  There are no labor contracts,
collective bargaining agreements, letters of undertakings or other

         5.26    LABOR DISPUTES.  To the Knowledge of Southern, each Southern
Company is in material compliance with all federal and state laws respecting
employment and employment practices, terms and conditions of employment, wages
and hours.  No Southern Company is or has been engaged in any unfair labor
practice, and, to the Knowledge of Southern, no unfair labor practice complaint
against any Southern Company is pending before the National Labor Relations
Board.  Relations between management of each Southern Company and the employees
are amicable and there have not been, nor to the
<PAGE>   25

Knowledge of Southern, are there presently, any attempts to organize employees,
nor to the Knowledge of Southern, are there plans for any such attempts.

         5.27    DERIVATIVE CONTRACTS.  No Southern Company is a party to 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

shall use reasonable good faith efforts to prepare all necessary filings with
any Agencies which may be necessary for approval to consummate the transactions

                 (b)      Blue Sky Permits.  BancGroup shall use its best
efforts to obtain, prior to the effective date of the Registration Statement,
all necessary state securities Law or "blue sky" Permits and approvals required
to carry out the transactions contemplated by this Agreement.

                 (c) Financial Statements.  BancGroup shall furnish to
Southern:

                          (i)     As soon as practicable and in any event
within forty-five (45) days after the end of each quarterly period (other than
the last quarterly period) in each fiscal year, consolidated statements of
operations of BancGroup for such period and for the period beginning at the
commencement of the fiscal year and ending at the end of such quarterly period,

audit reports submitted to BancGroup by independent auditors in connection with
each annual, interim or special audit of the books of BancGroup made by such
accountants;

                          (iii)   As soon as practicable, copies of all such
financial statements and reports as it shall send to its stockholders and of
such regular and periodic reports as BancGroup may file with the SEC or any

<PAGE>   26


                          (iv)    With reasonable promptness, such additional
financial data as Southern may reasonably request.

                 (d)      No Control of Southern by BancGroup.  Notwithstanding
any other provision hereof, until the Effective Date, the authority to
establish and implement the business policies of Southern shall continue to
reside solely in Southern's officers and board of directors.

                 (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 Southern Company shall, at BancGroup's option, either became
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 Southern 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.  Employees of any Southern Company who become
employees of the Resulting Corporation or its Subsidiaries 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 Southern
Company 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 Southern 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 Southern
Company employee shall be given credit for covered expenses paid by that
employee under comparable employee benefit plans of the Southern 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; Directors and Officers Insurance

                 (i)  From and after the Effective Date, BancGroup shall
indemnify and advance costs and expenses (including reasonable attorneys fees,
disbursements and expenses) and hold harmless each present and former director
and/or officer of Southern or its Subsidiaries determined as of the Effective
Date (the "Indemnified Parties"), against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages,
settlements or liabilities (collectively, "Costs") incurred in connection with
any claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative (each a "Claim"), arising out of or pertaining
to matters existing or occurring at or prior to the Effective Date, whether
asserted or claimed prior to, at or after the
<PAGE>   27

Effective Date to the fullest extent that Southern would have been required
under Florida law and its Articles of Incorporation or Bylaws in effect on the
date hereof, to indemnify such person (and also advance expenses as incurred to
the fullest extent permitted under applicable law).

                 (ii)  Any Indemnified Party wishing to claim indemnification
under Section 6.1 (i) shall notify BancGroup within forty-five (45) days of the
Indemnified Party's receipt of a notice of any Claim, but the failure to so
notify shall not relieve BancGroup of any liability it may have to such
Indemnified Party if such failure does not materially prejudice the
Indemnifying Party.  In the event of any claim (whether arising before or after
the Effective Date), (i) BancGroup shall have the right to assume the defense
thereof, and 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 elects not to assume such defense, or counsel for the indemnified
Parties advises that there are issues which raise conflicts of interest between
BancGroup and the Indemnified Parties, the Indemnified Parties may retain
counsel satisfactory to them, and BancGroup shall pay the reasonable fees and
expenses of such counsel for the Indemnified Parties promptly after statements
therefore are received; provided, however, that BancGroup shall be obligated
pursuant to this paragraph (ii) to pay for only one firm of counsel for all
Indemnified Parties in any jurisdiction unless the use of one counsel for such
Indemnified Parties will present such counsel with a conflict of interest, (ii)
the Indemnified Parties will cooperate in the defense of any such matter, and
(iii) and BancGroup shall not be liable for any settlement effected without its
prior written consent which shall not be unreasonably withheld.  If such
indemnity with any respect to any Indemnified Party is unenforceable against
BancGroup, then BancGroup and the Indemnified Party shall contribute to the
amount payable in such proportion as is appropriate to reflect relative faults
and benefits.

                 (iii)  For a period of four (4) years after the Effective
Date, BancGroup shall cause to be maintained in effect the current policies
with directors and officers liability insurance maintained by Southern
(provided that BancGroup may substitute therefore policies of at least the same
coverage and amounts containing terms and conditions which are no less
advantageous to such directors and officers and provided that the deductible
amount on BancGroup's policies may be higher than that for existing Southern
policies) with respect to claims arising from facts or events which occurred
before the Effective Date, provided that such policies may be maintained at a
cost that is comparable to the cost of such policies as of the date of this
Agreement.

                 (iv)  If BancGroup or any of its successors and assigns, (i)
shall consolidate with or merge into any other corporation or entity and shall
not be the continuing or surviving corporation or entity of such consolidation
or merger, or (ii) shall transfer all or substantially all of its property and
assets to any individual, corporation or other entity, then, in each such case,
proper provision shall be made so that the successors and assigns of BancGroup
and its Subsidiaries shall assume the obligations set forth in this section.

                 (v)  The provisions of this Section 6.1(g) are intended to be
for the benefit of, and shall be enforceable by each Indemnified Party, and
each Indemnified Party's heirs and representatives.

with BancGroup as follows:

                 (a)      Operations.  Southern will conduct its business
and the business of each Southern Company in a proper and prudent manner and
will use its best efforts to maintain its relationships with its depositors,
customers and employees.  No Southern Company will engage in any material
transaction outside the ordinary course of business or make any material change
in its accounting policies or methods of operation, nor will Southern permit
the occurrence of any change or event which would render any of the
representations and warranties in Article 5 hereof untrue in any material
respect at and as of the Effective Date with the same effect as though such
representations and warranties had been made at and as of such Effective Date.
Southern may request the consent of BancGroup to any of the foregoing actions
by furnishing BancGroup with a written request which describes the action
proposed to be taken by Southern.  Such consent shall not be unreasonably
withheld.  BancGroup shall have a period of 10 days from the date on which it
receives such request within which to notify Southern of either its consent or
refusal to consent, to the proposed action.  BancGroup's failure to respond to
any such request within such 10 day period shall be deemed to constitute a
consent to the action proposed in Southern's request.

                 (b)      Stockholders Meeting;  Best Efforts.  Southern will
cause the Stockholders Meeting to be held for the purpose of approving the
Merger as soon as practicable after the effective date of the Registration
Statement, and will use its best efforts to bring about the transactions
contemplated by this Agreement, including stockholder approval of this
Agreement, as soon as practicable unless this Agreement is terminated as
provided herein.

                 (c)      Prohibited Negotiations.  Until the termination of
this Agreement, neither Southern nor any of Southern's directors or officers
(or any person representing any of the foregoing) shall 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, Southern or any business combination involving
Southern or any Southern Company other than as contemplated by this Agreement.
Southern will notify BancGroup immediately if any such inquiries or proposals
are received by Southern, if any such information is requested from Southern,
or if any such negotiations or discussions are sought to be initiated with
Southern, and Southern shall instruct Southern's officers, directors, agents or
affiliates or their subsidiaries to refrain from doing any of the above;
provided, however, that nothing contained herein shall be deemed to prohibit
any officer or director of Southern from fulfilling his fiduciary duty or from
taking any action that is required by Law.

                 (d)      Director Recommendation.  The members of the Board of
Directors of Southern agree to support publicly the Merger, provided, however,
that nothing contained herein shall be deemed to prohibit any officer or
director of Southern from fulfilling his fiduciary duty or from taking any
action that is required by Law.
<PAGE>   29

                 (e)      Shareholder Voting.  Southern shall on the date of

ending at the end of such quarterly period, and a consolidated statement of
financial condition of Southern as of the end of such quarterly period, setting
forth in each case in comparative form figures for the corresponding periods
ending in the preceding fiscal year, subject to changes resulting from year-end
adjustments;

                 (ii)  Promptly upon receipt thereof, copies of all audit

                 (iii)  As soon a practicable, copies of all such financial
statements and reports as it shall send to its stockholders and of such regular

                 (iv)  With reasonable promptness, such additional financial
data as the BancGroup may reasonably request.

referenced in section 5.8 hereof were in full force and effect and have not

                 (e)      to such persons' knowledge, the Proxy Statement
delivered to Southern's stockholders, or any amendments or revisions thereto so
delivered, as of the date thereof, did not contain or incorporate by reference
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, not
misleading in light of the circumstances under which they were made (it being
understood that such persons need only express a statement as to information

                 (f)      the conditions set forth in this Article 10 insofar

         10.4    OPINION OF COUNSEL.  BancGroup shall have received an opinion
of Shutts & Bowen, counsel to Southern, dated as of the Closing, in form
reasonably satisfactory to BancGroup, as to matters set forth in Exhibit C
hereto.

         10.5    CONTROLLING SHAREHOLDERS.    Each shareholder of Southern
who may be an "affiliate" of Southern, within the meaning of Rule 145 of the
general rules and regulations under the 1933 Act shall have executed and
delivered an agreement satisfactory to BancGroup to the effect that such person
shall not make a "distribution" (within the meaning of Rule 145) of the Common
Stock which he receives upon the Effective Date and that such Common Stock will
be held subject to all applicable provisions of the 1933 Act and the rules and
regulations of the SEC thereunder.  The agreement will also provide that no
affiliate of Southern will sell or otherwise reduce such affiliate's risk
relative to any shares of BancGroup Common Stock received in the Merger until
financial results concerning at least 30 days of post-Merger combined
operations have been published.  Southern recognizes and acknowledges that
Common Stock issued to such persons may bear a legend evidencing the agreement
described above.

         10.6    OTHER MATTERS.  There shall have been furnished to counsel for
BancGroup certified copies of such corporate records of Southern and copies of
such other documents as such counsel may reasonably have requested for such
purpose.

Southern have exercised dissenters rights of appraisal under section 3.6 does

         10.8    POOLING OF INTERESTS.  BancGroup shall have received the
written opinion of Coopers & Lybrand, L.L.P., that the Merger will qualify for
the pooling of interests method of accounting under generally accepted
accounting principles.

         10.9    MATERIAL EVENTS.  There shall have been no determination by
the board of directors of BancGroup that the transactions contemplated by this
Agreement have become impractical because of any state of war or declaration of
a banking moratorium in the United States.

Agreement) in the event of a breach by the other Party of any representation or
warranty contained in this Agreement which cannot be or has not been cured
within thirty (30) days after the giving of written notice to the breaching
Party of such breach and which breach would provide the non-breaching Party the
ability to refuse to consummate the Merger under the standard set forth in
section 10.1 of this Agreement in the case of BancGroup and section 9.1 of this
Agreement in the case of Southern;

                 (c)      by the board of directors of either Party (provided

Party contained in this Agreement shall not have been satisfied in full;

Southern if all transactions contemplated by this Agreement shall not have been
consummated on or prior to September 30, 1996, if the failure to consummate the
transactions provided for in this Agreement on or before such date is not
caused by any breach of this Agreement by the Party electing to terminate
pursuant to this section 13.2(d); or

                 (e)      by the board of directors of either BancGroup or
Southern if the average of the closing prices of the BancGroup Common Stock

greater than $36.625.

warranty or representation contained in this Agreement made in good faith, and,
in that case, the expenses incurred shall be borne as set forth in section 15.1

         15.4    COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed to constitute an original.  Each such counterpart
shall become effective when one counterpart has been signed by each Party
thereto.

         15.5    HEADINGS.  The headings of the various articles and sections
of this Agreement are for convenience of reference only and shall not be deemed
a part of this Agreement or considered in construing the provisions thereof.

         15.6    SEVERABILITY.  Any term or provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining terms and provisions thereof or affecting the
validity or enforceability of such provision in any other jurisdiction, and if
any term or provision of this Agreement is held by any court of competent
jurisdiction to be void, voidable, invalid or unenforceable in any given
circumstance or situation, then all other terms and provisions, being
severable, shall remain in full force and effect in such circumstance or
situation and the said term or provision shall remain valid and in effect in
any other circumstances or situation.

         15.7    CONSTRUCTION.  Use of the masculine pronoun herein shall be
deemed to refer to the feminine and neuter genders and the use of singular
references shall be deemed to include the plural and vice versa, as

         15.9    EQUITABLE REMEDIES.  The parties hereto agree that, in the
event of a breach of this Agreement by either Party, the other Party may be
without an adequate remedy at law owing to the unique nature of the contemplated
transactions.  In recognition thereof, in addition to (and not in lieu of) any
remedies at law that may be available to the non-breaching Party, the
non-breaching Party shall be entitled to obtain equitable relief, including the
remedies of specific performance and injunction, in the event of a breach of
this Agreement by the other Party, and no attempt on the part of the
non-breaching Party to obtain such equitable relief shall be deemed to
constitute an election of remedies by the non-breaching Party that would
preclude the non-breaching Party from obtaining any remedies at law to which it
would otherwise be entitled.

         15.10   ATTORNEYS' FEES.  If any Party hereto shall bring an action at
law or in equity to enforce its rights under this Agreement (including an
action based upon a misrepresentation or the breach of any warranty, covenant,

shall be entitled to recover from the
<PAGE>   44

other Party its costs and expenses incurred in connection with such action
(including fees, disbursements and expenses of attorneys and costs of
investigation).

         15.11   NO WAIVER.  No failure, delay or omission of or by any Party
in exercising any right, power or remedy upon any breach or Default of any
other Party shall impair any such rights, powers or remedies of the Party not
in breach or Default, nor shall it be construed to be a wavier of any such
right, power or remedy, or an acquiescence in any similar breach or Default;
nor shall any waiver of any single breach or Default be deemed a waiver of any
other breach or default theretofore or thereafter occurring.  Any waiver,
permit, consent or approval of any kind or character on the part of any Party
of any provisions of this Agreement must be in writing and be executed by the
Parties to this Agreement and shall be effective only to the extent
specifically set forth in such writing.

         15.12   REMEDIES CUMULATIVE.  All remedies provided in this Agreement,
by law or otherwise, shall be cumulative and not alternative.

         15.13   ENTIRE CONTRACT.  This Agreement and the documents and
instruments referred to herein constitute the entire contract between the
parties to this Agreement and supersede all other understandings with respect
to the subject matter of this Agreement.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Commercial Bancorp of Georgia, Inc.
 
     In our opinion, the consolidated statement of condition and the related
consolidated statements of income, of changes in shareholders' equity and of
cash flows as of and for each of the two years in the period ended December 31,
1993 of the former Commercial Bancorp of Georgia, Inc. and its subsidiary (not
presented separately herein) present fairly, in all material respects, the
financial position, the results of their operations and their cash flows for
each of the two years in the period ended December 31, 1993, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

shall be reduced pro rata as to all stockholders who have not elected to
receive 100% of the Merger Consideration in cash.  If the aggregate amount of
cash to be paid in the Merger is greater than 50% of the Merger Consideration
based upon the Election Forms which have been properly filed, then the
aggregate amount of cash will be reduced and a sufficient amount of cash shall
be distributed pro rata to all stockholders of the Bank who have not elected to
receive 100% of the Merger Consideration in BancGroup Common Stock, regardless
of whether such stockholders have filed an Election Form, so that the aggregate
amount of Merger Consideration to be paid in cash in the Merger will equal 50%,
and the number of shares of BancGroup Common Stock otherwise required to be
distributed shall be increased pro rata as to all stockholders who have not
elected to received 100% of the Merger Consideration in BancGroup Common Stock.
Cash to be paid to any Bank stockholder exercising dissenters' rights of
appraisal shall be included as part of the Merger Consideration for determining
the amount of cash to be paid.  Interest will not be paid on any cash to be
paid as part of the Merger Consideration.

guardian, officer of a corporation, attorney-in-fact, or in any other
