Board of Directors of Bankshares for use at a special meeting of the
shareholders of Bankshares (the "Special Meeting") to be held on , , 1996, at

the New York Stock Exchange ("NYSE") on each of the ten trading days ending on
the trading day immediately preceding the date of consummation of the Merger,
provided that the Market Value shall not be less than $29.75 or more than
$37.75. The shares of BancGroup Common Stock are listed on the NYSE. The closing
price per share of the BancGroup Common Stock on the NYSE on October 31, 1996

     Consummation of the Merger requires, among other things, the affirmative
vote of the holders of at least a majority of the outstanding shares of
Bankshares Common Stock.
 
     BancGroup has filed a Registration Statement pursuant to the Securities Act
of 1933, as amended (the "Securities Act"), to register the shares of the
BancGroup Common Stock to be issued in connection with the Merger as well as

with respect to the BancGroup Common Stock to be issued in the Merger and upon
the exercise of employee stock options assumed in the Merger. This Prospectus

TERMS OF THE MERGER
 
     The Agreement provides for the Merger of Bankshares with and into
BancGroup, with BancGroup to be the surviving corporation. Upon the date of
consummation of the Merger (the "Effective Date"), each outstanding share of
Bankshares Common Stock shall be converted by operation of law and without any
action by any holder thereof into shares of BancGroup Common Stock (the "Merger
Consideration"). Specifically, each outstanding share of Bankshares Common Stock
shall be converted into a number of shares of
 
                                        1
<PAGE>   13
 
BancGroup Common Stock which is equal to $27.39 divided by the Market Value. For
this purpose, "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 BancGroup Common Stock as
reported by the NYSE on each of the ten trading days ending on the trading day
immediately preceding the Effective Date; provided, however, that regardless of
the actual Market Value as calculated above, Market Value shall not be less than
$29.75, nor more than $37.75. Accordingly, the maximum number of shares of
BancGroup Common Stock to be issued in the Merger shall be 645,240 (based upon a
minimum Market Value of $29.75) and the minimum number of shares of BancGroup
Common Stock to be issued in the Merger shall be 508,500 (based upon a maximum
Market Value of $37.75), assuming 700,836 shares of Bankshares Common Stock
outstanding.
 
     To the extent that the number of shares of Bankshares Common Stock may
increase based upon the exercise of options respecting Bankshares Common Stock
or the conversion of Bankshares Series A 7% Convertible Subordinated Debentures,
the aggregate number of shares of BancGroup Common Stock to be issued in the
Merger shall be increased with each share of Bankshares Common Stock outstanding
at the Effective Date being exchanged for a number of shares of BancGroup Common
Stock which is equal to one share of Bankshares Common Stock multiplied by the
Exchange Ratio, i.e., $27.39 divided by the Market Value. No fractional shares
of BancGroup Common Stock will be issued in connection with the Merger. To the
extent cash is paid in lieu of fractional shares, the cash will be paid based
upon the Market Value.
 
     As of the date of this Prospectus, Bankshares had granted options (the
"Bankshares Options") which entitled the holders thereof to acquire up to 46,750
shares of Bankshares Common Stock. On the Effective Date, BancGroup will assume
all Bankshares Options outstanding, and each such option shall represent the
right to acquire BancGroup Common Stock on substantially the same terms
applicable to the Bankshares Options. The number of shares of BancGroup Common
Stock to be issued pursuant to such options shall equal the number of shares of
Bankshares Common Stock subject to the Bankshares Options multiplied by the
Exchange Ratio, as defined below, provided that no fractions of shares of
BancGroup Common Stock shall be issued. If a fractional share exists, the number
of shares of BancGroup Common Stock to be issued upon the exercise of Bankshares
Options, shall equal the number of whole shares obtained by rounding to the
nearest whole number, taking into account such fraction. The exercise price for
the acquisition of BancGroup Common Stock shall be the exercise price for each
share of Bankshares Common Stock subject to such options divided by the Exchange
Ratio, adjusted appropriately for any rounding to whole shares that may be done.
The "Exchange Ratio" shall mean the result obtained by dividing $27.39 by the
Market Value.
 
     On the Effective Date, BancGroup will assume Bankshares' Series A 7%
Convertible Subordinated Debentures (the "Series A Debentures") respecting the
issuance of 64,773 shares of Bankshares Common Stock. The Series A Debentures
shall be convertible into shares of BancGroup Common Stock, with each share of
Bankshares Common Stock that would have been issued upon conversion of such
debentures being convertible into a number of shares of BancGroup Common Stock
which is equal to one share of Bankshares Common Stock multiplied by the
Exchange Ratio. No fractions of shares of BancGroup Common Stock will be issued
upon conversion of such debentures, and any fractions to be issued shall be paid
in cash based upon the market value of any fraction at the time of conversion,
as set forth in such debentures.
 
     Bankshares shareholders will be given notice of the Merger promptly after
the Effective Date of the Merger. Certificates for the BancGroup Common Stock
will not be distributed or dividends paid until shareholders surrender their
certificates representing their shares of Bankshares Common Stock.
 
     See "THE MERGER -- Conversion of Bankshares Common Stock," "Surrender of
Bankshares Common Stock Certificates," "Treatment of Bankshares Options," and
"Treatment of Series A Debentures."

By Management."
 
RECOMMENDATION OF BANKSHARES' BOARD OF DIRECTORS
 
     The Board of Directors of Bankshares has unanimously approved the
Agreement. THE BOARD OF DIRECTORS OF BANKSHARES BELIEVES THAT THE MERGER IS FAIR
TO, AND IN THE BEST INTERESTS OF, THE SHAREHOLDERS OF BANKSHARES, AND RECOMMENDS
THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF THE AGREEMENT. For a discussion of
the factors considered by the Board of Directors in reaching its conclusions,
see "THE MERGER -- Background of the Merger" and "Bankshares' Board of
Directors' Reasons for Approving the Merger."
 
OPINION OF FINANCIAL ADVISOR
 
     Bankshares has received an opinion from T. Stephen Johnson & Associates,
Inc. ("Stephen Johnson") that the Merger is fair to the shareholders of
Bankshares from a financial point of view. See "THE MERGER -- Opinion of
Financial Advisor."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain of the directors and executive officers of Bankshares hold
Bankshares Options which entitle them to purchase, in the aggregate, up to
46,750 shares of Bankshares Common Stock. Under the terms of the Agreement, any
Bankshares Options which are not exercised prior to the Effective Date will be
assumed by BancGroup. See "THE MERGER -- Conversion of Bankshares Common Stock,"
and "Treatment of Bankshares Options."
 
     Certain of the directors and executive officers of Bankshares own Series A
Debentures which are convertible into, in the aggregate, up to 15,906 shares of
Bankshares Common Stock. Under the terms of the Agreement, any Series A
Debentures which are not converted prior to the Effective Date will be assumed
by BancGroup. See "The Merger -- Conversion of Bankshares Common Stock" and
"Treatment of Series A Debentures."
 
     The Agreement stipulates that it is a condition to BancGroup's obligation
to close the Merger that Charles Y. Allgood, president of Bankshares and the
Bank, enter into a severance agreement with BancGroup that will provide a
lump-sum payment to Mr. Allgood if BancGroup terminates Mr. Allgood's employment
within one year after the Effective Date, under certain circumstances.
 
     On the Effective Date, all employees of Bankshares (including its executive
officers) shall, at BancGroup's option, either become employees of BancGroup or
its subsidiaries or be entitled to severance benefits in accordance with
BancGroup's severance policy as of the date of the Agreement. All employees of
Bankshares who become employees of BancGroup or its subsidiaries on the
Effective Date shall be entitled, to the extent permitted by applicable law, to
participate in all benefit plans of BancGroup to the same extent as BancGroup's
employees. BancGroup has indicated that it currently intends to retain each of
the executive officers of Bankshares following the consummation of the Merger
(although it has no obligation to do so), on substantially the same terms and
conditions (including salary) as currently earned by such executive officers.
 
     Under the Agreement, BancGroup has agreed to indemnify the directors and
executive officers of Bankshares against certain claims and liabilities arising
out of or pertaining to matters existing or occurring at or prior to the
Effective Date, to the fullest extent that Bankshares would have been permitted
under Georgia law, or under its Articles of Incorporation or Bylaws, to
indemnify such persons (and also to advance expenses as incurred to the fullest
extent permitted under applicable law).
 
     Except as described above, none of the directors or executive officers of
Bankshares, and no associate of any such person, has any substantial direct or
indirect interest in the Merger, other than an interest arising from the
ownership of Bankshares Common Stock.
 
     See "THE MERGER -- Interests of Certain Persons in the Merger."

VOTE REQUIRED
 
     Under Georgia law, the Agreement must be approved by the affirmative vote
of the holders of at least a majority of the outstanding shares of Bankshares
Common Stock. Each share of Bankshares Common Stock is entitled to one vote on
the Agreement. Approval of the Agreement and the Merger by BancGroup
stockholders is not required under Delaware, Georgia or other applicable law, or
the rules of the NYSE on which the BancGroup Common Stock is listed. See "THE
SPECIAL MEETING."
 
     Only holders of record of Bankshares Common Stock at the close of business
on        , 1996 are entitled to notice of and to vote at the Special Meeting.
As of such date, [700,836] shares of Bankshares Common Stock were issued and
outstanding. As of the Record Date, Bankshares's directors, executive officers
and their affiliates held approximately 39% of the outstanding shares of
Bankshares Common Stock. As of the same date, the directors, executive officers
and affiliates of BancGroup held no shares of Bankshares Common Stock. See "THE
SPECIAL MEETING."
 
     BancGroup and the directors of Bankshares have entered into letter
agreements under which the directors have agreed, among other things, to vote or
cause the record owner to vote any shares of Bankshares Common Stock held by
such directors in favor of the Merger and the Agreement and in favor of the
other transactions contemplated between Bankshares and BancGroup pursuant to the
terms of the Agreement and against any business combination or other
reorganization of any kind involving Bankshares or its subsidiaries with any
entity other than BancGroup. As of the Record Date, the directors owned, either
beneficially or of record, 255,127 shares of Bankshares Common Stock or
approximately 36% of the outstanding shares of Bankshares Common Stock held on
such date. The parties anticipate that all of the shares of Bankshares Common
Stock held by the directors will be voted in favor of the Agreement and the
Merger. Directors and executive officers of BancGroup beneficially own in the
aggregate 2,187,008 shares of BancGroup Common Stock representing approximately
13% of the outstanding shares, but no vote of BancGroup stockholders is required
to approve the Merger. See "THE SPECIAL MEETING."
 
     Proxies should be returned to Bankshares in the envelope enclosed herewith.
Shareholders of Bankshares submitting proxies may revoke their proxies by (i)
giving notice of such revocation in writing to the Secretary of Bankshares at or
prior to the Special Meeting, (ii) by executing and delivering a proxy bearing a
later date to the Secretary of Bankshares at or prior to the Special Meeting, or
(iii) by attending the Special Meeting and voting in person. Because approval of
the Merger requires the approval of at least a majority of the outstanding
shares of Bankshares Common Stock, failure to submit a proxy or failure to vote
in person at the Special Meeting will have the same effect as a negative vote.
See "THE SPECIAL MEETING -- Solicitation, Voting and Revocation of Proxies."
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
     Any shareholder of Bankshares may dissent from the Merger and obtain the
fair value of such holder's Bankshares Common Stock in cash rather than receive
shares of BancGroup Common Stock if such shareholder (i) has delivered notice in
writing to Bankshares before the vote is taken at the Special Meeting that he or
she intends to demand payment of his shares if the Merger is consummated and
(ii) votes against the Merger or refrains from voting on the Merger. If a
shareholder votes against the Merger or refrains from voting on the Merger but
does not deliver the notice in writing to Bankshares before the shareholder vote
on the Merger occurs, such shareholder will lose his or her appraisal rights. If
the Merger is authorized at the Special Meeting, BancGroup will deliver a
written dissenters' notice within ten (10) days of the Effective Date to all
holders of Bankshares Common Stock who have provided notice that they intend to
seek payment. Shareholders wishing to exercise dissenters' rights must follow
properly all requirements for the exercise of such rights as set forth in
Article 13 of the Georgia Business Corporation Code, a copy of which is attached
as Appendix B hereto.
 
     Any shareholder who properly exercises appraisal rights and receives fair
market value for his or her 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."

CONDITIONS TO THE MERGER
 
     The parties' obligation to consummate the Merger is subject to the
satisfaction (or waiver, to the extent permitted by law) of various conditions
set forth in the Agreement.
 
     The mutual obligations of the parties to consummate the Merger are subject
to the following conditions, among others: (i) the approval of the Agreement by
the holders of at least a majority of the outstanding shares of Bankshares
Common Stock; (ii) any required approvals of the Merger by the Board of
Governors of the Federal Reserve System (the "Federal Reserve") and the Georgia
Department of Banking and Finance (the "Georgia Department"), and the approval
of the merger of the Bank with Colonial Bank by the Federal Deposit Insurance
Corporation ("FDIC") and the Georgia Department, (iii) the absence of any
pending or threatened litigation which seeks to restrain or prohibit the Merger;
and (iv) the consummation of the Merger on or before May 31, 1997.
 
     The obligation of Bankshares to consummate the Merger is further subject to
several conditions, including: (i) the absence of any material adverse changes
in the financial condition or affairs of BancGroup; and (ii) the shares of
BancGroup Common Stock to be issued under the Agreement having been approved for
listing on the NYSE.
 
     The obligation of BancGroup to consummate the Merger is subject to various
conditions, including: (i) the absence of any material adverse change in the
financial condition or affairs of Bankshares; and (ii) the Merger qualifying for
pooling of interests accounting treatment.
 
     Applications for approval of the Merger by the Federal Reserve, the FDIC
and the Georgia Department were filed with such agencies on or about November 6,
1996. The regulatory approval process is expected to take approximately three
months from that date.
 
  See "THE MERGER -- Conditions to Consummation of the Merger" and "Regulatory
                                  Approvals."
 
AMENDMENT OR TERMINATION OF AGREEMENT
 
     The Boards of Directors of BancGroup and Bankshares may agree to amend or
terminate the Agreement at any time prior to the Effective Date. However, the
Board of Directors of Bankshares shall not agree to any amendments to the
Agreement which would alter the Merger Consideration or which, in the opinion of
the Board of Directors of Bankshares, would adversely affect the rights of the
shareholders of Bankshares, unless such amendments are approved by the holders
of a majority of the outstanding Bankshares Common Stock. Such amendments may
require the filing of an amendment of the Registration Statement, of which this
Prospectus forms a part, with the Commission. See "THE MERGER -- Amendment or
Termination."
 
COMPARISON OF SHAREHOLDER RIGHTS
 
     The rights of the holders of the Bankshares Common Stock may be different
from the rights of the holders of the BancGroup Common Stock. A discussion of
these rights and a comparison thereof is set forth in the section of this
Prospectus at "COMPARATIVE RIGHTS OF STOCKHOLDERS."
 
FEDERAL INCOME TAX CONSEQUENCES
 
     No ruling with respect to the federal income tax consequences of the Merger
to Bankshares' shareholders will be requested from the Internal Revenue Service
(the "IRS"). BancGroup and Bankshares have received an opinion from counsel to
BancGroup, Miller, Hamilton, Snider & Odom, L.L.C., Mobile, Alabama, that, among
other things, a shareholder of Bankshares who exchanges shares of Bankshares
Common Stock for BancGroup Common Stock shall not recognize gain, except that
shareholders of Bankshares will recognize gain to the extent such shareholders
receive cash in lieu of fractional shares of BancGroup Common Stock or cash as a
result of the exercise of dissenters' appraisal rights. See "APPROVAL OF THE
MERGER -- Certain Federal Income Tax Consequences."

transaction by BancGroup for accounting purposes. See "THE MERGER -- Accounting
Treatment."

CERTAIN LEGAL RESTRICTIONS ON ACQUISITIONS OF CONTROL
 
     Certain restrictions under Delaware law prevent a person who beneficially
owns 15% or more of the BancGroup Common Stock from engaging in a "business
combination" with BancGroup unless certain conditions are satisfied. Also, the
Change in Bank Control Act of 1978 prohibits a person from acquiring "control"
of BancGroup unless certain notice provisions with the Federal Reserve Board
have been satisfied.

     30, 1996 which assumes the transaction was consummated on the latest
     balance sheet date in accordance with Rule 11.02(b) of Regulation S-X.
(a) Net Income per share for the year ended December 31, 1993 represents income
     before extraordinary items and cumulative effect of change in accounting
     principle.
(b) Pro forma equivalent per share amounts are calculated by multiplying the pro
     forma combined total income per share and the pro forma combined total book
     value per share of BancGroup by the conversion ratio so that the per share
     amounts are equated to the respective values for one share of

     Bankshares. For the purposes of these pro forma equivalent per share
     amounts, a .7815 BancGroup common stock share conversion ratio is utilized.
     The ratio is based on the 10-day average of the closing market price of
     Colonial BancGroup, Inc. common stock of $35.05 at September 19, 1996
     ($27.39/35.05 = .7815).
(c) Pro forma equivalent dividends per share are shown at BancGroup's Common
     Stock dividend per share rate multiplied by the .7815 conversion ratio per
     share of Bankshares common stock (see note (b)). 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.
(d) Pro forma net income excludes two non-recurring charges for employee
     severance and bonuses expected to result from the proposed pooling of
     interests business combination with Jefferson in the amount of $4.4
     million, net of tax.

                              THE SPECIAL MEETING
 
GENERAL
 
     This Prospectus is being furnished to the shareholders of Bankshares in
connection with the solicitation of proxies by the Board of Directors of
Bankshares for use at the Special Meeting. The purpose of the Special Meeting is
to consider and vote upon the proposed Merger of Bankshares with and into
BancGroup. BancGroup will be the surviving corporation in the Merger.
 
     This Prospectus is also furnished by BancGroup in connection with the offer
of shares of BancGroup Common Stock to be issued in the Merger. No vote of
BancGroup stockholders is required to approve the Merger.
 
     The Board of Directors of Bankshares believes that the Merger is in the
best interests of Bankshares and its shareholders and unanimously recommends
that shareholders vote "FOR" the Merger (item 1 on the proxy card).
 
RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED FOR THE MERGER
 
     The Board of Directors of Bankshares has fixed the close of business on
          , 1996, as the Record Date for determination of shareholders entitled
to vote at the Special Meeting. There were [471] record holders of Bankshares
Common Stock as of such date. On that date, there were [700,836] shares of
Bankshares Common Stock outstanding, each entitled to one vote per share.
Bankshares is obligated to issue an additional 46,750 shares of Bankshares
Common Stock upon the exercise of outstanding Bankshares Options. Bankshares is
also obligated to issue an additional 64,773 shares of Bankshares Common Stock
upon the conversion of the outstanding Series A Debentures.
 
     The affirmative vote of the holders of at least a majority of the
outstanding shares of Bankshares Common Stock, whether or not present or
represented at the Special Meeting, is required to approve the Agreement. Broker
non-votes and abstentions will not be counted as votes cast for or against the
proposal to approve the Agreement and, as a result, will have the same effect as
votes cast against the Agreement. Each holder of record of shares of Bankshares
Common Stock is entitled to cast, for each share registered in his or her name,
one vote on the Agreement and on each other matter presented to a vote of
shareholders at the Special Meeting.
 
     As of the Record Date, directors and executive officers of Bankshares and
their affiliates were the owners of 277,247 shares of Bankshares Common Stock,
representing approximately 39% of the outstanding shares of Bankshares Common
Stock. All of such persons will vote their Bankshares Common Stock in favor of
the Merger.
 
     If the Merger is approved at the Special Meeting, Bankshares is expected to
merge with and into BancGroup promptly after the other conditions to the
Agreement are satisfied. See "THE MERGER -- Conditions of Consummation of the
Merger."
 
     THE BOARD OF DIRECTORS OF BANKSHARES URGES THE SHAREHOLDERS OF BANKSHARES
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 Bankshares, without receiving special compensation therefor, may
solicit proxies from Bankshares's shareholders 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 Bankshares Common Stock.
 
                                       10

     Bankshares will bear the cost of assembling and mailing this Prospectus and
other materials furnished to shareholders of Bankshares. It will also pay all
other expenses of solicitation, including the expenses of brokers, custodians,
nominees, and other fiduciaries who, at the request of Bankshares, mail material
to or otherwise communicate with beneficial owners of the shares held by them.
BancGroup will pay all expenses incident to the registration of the BancGroup
Common Stock to be issued in connection with the Merger.
 
     Shares of Bankshares Common Stock represented by a proxy properly signed
and received at or prior to the Special Meeting, unless properly revoked, will
be voted in accordance with the instructions on the proxy. IF A PROXY IS SIGNED
AND RETURNED WITHOUT ANY VOTING INSTRUCTIONS, SHARES OF BANKSHARES COMMON STOCK
REPRESENTED BY THE PROXY WILL BE VOTED FOR THE PROPOSAL TO APPROVE THE
AGREEMENT, AND, AT THE DISCRETION OF THE HOLDER OF THE PROXY, FOR ANY NECESSARY
ADJOURNMENT OF THE SPECIAL MEETING. A shareholder may revoke any proxy given
pursuant to this solicitation by: (i) delivering to the Secretary of Bankshares,
prior to or at the Special Meeting, a written notice revoking the proxy; (ii)
delivering to the Secretary of Bankshares, at or prior to the Special Meeting, a
duly executed proxy relating to the same shares bearing a later date; or (iii)
by voting in person at the Special Meeting. All written notices of revocation
and other communications with respect to the revocation of Bankshares' proxies
should be addressed to:

     Attendance at the Special Meeting will not, in and of itself, constitute a
revocation of a proxy.
 
     Votes will be tabulated by one or more inspectors of election appointed by
Bankshares. 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 whether
a quorum is present at the Special Meeting.
 
     The Board of Directors of Bankshares is not aware of any business to be
acted upon at the Special Meeting other than consideration of the Merger
described herein. If, however, other matters are properly brought before the
Special Meeting, or any adjournments or postponements thereof, the persons
appointed as proxies will have the discretion to vote or act on such matters
according to their best judgment. Proxies voted in favor of the Merger, or
proxies as to which no voting instructions are given, will be voted to adjourn
the Special Meeting, if necessary, in order to solicit additional proxies in
favor of the Merger. Proxies voted against the Merger or abstentions will not be
voted for an adjournment. See "ADJOURNMENT OF THE SPECIAL MEETING."
 
EFFECT OF MERGER ON OUTSTANDING BANCGROUP COMMON STOCK
 
     On the Effective Date, and assuming a Market Value, calculated as of
September 19, 1996, of $35.05, BancGroup will issue 547,672 shares of BancGroup
Common Stock to the shareholders of Bankshares pursuant to the Merger, not
counting any BancGroup Common Stock to be issued pursuant to Bankshares Options
or Bankshares Series A Debentures. These 547,672 shares of BancGroup Common
Stock would represent approximately 3.2% of the total number of shares of
BancGroup Common Stock outstanding following the Merger, not counting any
additional shares BancGroup may issue, including shares to be issued pursuant to
other pending acquisitions.
 
                                   THE MERGER
 
     THE FOLLOWING SETS FORTH A SUMMARY OF ALL MATERIAL PROVISIONS OF THE
AGREEMENT AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE AGREEMENT
ATTACHED HERETO AS APPENDIX A. ALL BANKSHARES SHAREHOLDERS ARE URGED TO READ THE
AGREEMENT AND THE APPENDICES IN THEIR ENTIRETY.
 
                                       11
<PAGE>   23
GENERAL
 
     The Agreement provides that, subject to shareholder ratification and
confirmation, receipt of necessary regulatory approval and certain other
conditions described below at "Conditions to Consummation of the Merger,"
Bankshares will merge with and into BancGroup. Upon completion of the Merger,
the corporate existence of Bankshares will cease, and BancGroup will succeed to
the business formerly conducted by Bankshares. Simultaneously with the Merger,
Bankshares' subsidiary bank, Dalton/Whitfield Bank & Trust, will be merged with
BancGroup's wholly owned subsidiary bank in Georgia, Colonial Bank.
 
BACKGROUND OF THE MERGER
 
     Between April 1995 and March 1996, Bankshares received four offers for
acquisition which were reviewed by the Board of Directors and declined as
inadequate. Three additional inquiries expressing interest in an acquisition
were also received but no actual offers were made.
 
     On June 19, 1996, Bankshares engaged the services of T. Stephen Johnson &
Associates. The firm was requested to develop a bid package and submit a list of
potential merger partners for the Board's review. The firm was also asked to
evaluate Bankshares' projected future value as an independent institution.
 
     On July 25, 1996, T. Stephen Johnson and Associates presented four bids to
the Board of Directors of Bankshares and reviewed the bids, along with
projections relating to Bankshares' future value as an independent institution.
Counsel to Bankshares reviewed with the Board its fiduciary obligations in
considering offers to acquire Bankshares. The meeting was then recessed to give
each director an opportunity to consider the information presented and was
reconvened on July 29, 1996. At the July 29 meeting, the Board unanimously
approved the offer submitted by BancGroup as being superior to the other offers
and to Bankshares' future value as an independent institution. The Board also
authorized bank management to execute a letter of intent with BancGroup.
 
     During the month of August 1996, both Bankshares and BancGroup conducted
due diligence investigations which were completed with satisfactory results. At
a special called meeting of the Board of Bankshares, counsel to Bankshares led a
detailed discussion of the content of a proposed definitive agreement. After a
lengthy discussion of the specific terms of the agreement, the Board unanimously
approved the acquisition of Bankshares on terms and conditions as substantially
set forth in the proposed agreement. They further authorized President and CEO
Charles Y. Allgood and Secretary Rita B. Gray to execute and deliver the
proposed agreement on behalf of Bankshares.
 
BANKSHARES' REASONS FOR APPROVING THE MERGER
 
     Bankshares' Board of Directors, after consideration of relevant business,
financial, legal, and market factors, approved the Agreement. Bankshares' Board
did not assign any relative or specific weight to the factors considered. The
factors considered included:
 
          (a) The alternatives to the Merger, including remaining an independent
              institution in light of the current economic conditions of the
              market and the competitive disadvantages as compared to the larger
              financial institutions operating in the market;
 
          (b) The value of the consideration to be received by Bankshares
              shareholders relative to the book value and earnings per share of
              Bankshares Common Stock;
 
          (c) Certain information concerning the financial condition, results of
              operations and business prospects of BancGroup;
 
          (d) The financial terms of recent business combinations in the
              financial services industry and a comparison of the multiples of
              selected combinations with the terms of the proposed transaction
              with BancGroup;
 
          (e) The marketability of Bankshares Common Stock;
 
          (f) The competitive and regulatory environment for financial
              institutions generally;
 
                                       12
<PAGE>   24
          (g) The fact that the Merger will enable Bankshares shareholders to
              exchange their shares of Bankshares Common Stock, in a tax-free
              transaction, for shares of common stock of a regional company, the
              stock of which is widely held and actively traded; and
 
          (h) BancGroup's ability to provide comprehensive financial services to
              its markets.
 
     THE BOARD OF DIRECTORS OF BANKSHARES RECOMMENDS THAT YOU VOTE "FOR"
APPROVAL OF THE AGREEMENT AND CONSUMMATION OF THE MERGER.
 
OPINION OF FINANCIAL ADVISOR
 
     T. Stephen Johnson & Associates, Inc. (the "Advisor") is an investment
banking and financial services firm located in Atlanta, Georgia. As part of its
investment banking business, Advisor engages in the review of the fairness of
bank acquisition transactions from a financial perspective and in the valuation
of banks and other businesses and their securities in connection with mergers,
acquisitions and other transactions. Neither Advisor nor any of its affiliates
has a material financial interest in Bankshares or BancGroup. Advisor was
selected to advise Bankshares' Board of Directors based upon its familiarity
with Bankshares, the regional community banking industry and its knowledge of
the banking industry as a whole. No instructions were given or limitations
imposed by the Bankshares Board of Directors upon Advisor regarding the scope of
its investigation or the procedures it followed in rendering its opinion.
 
     Advisor has rendered its opinion (the "Fairness Opinion") to the Board of
Directors of Bankshares that the consideration to be paid to the holders of
Bankshares common stock under the Agreement is fair to such shareholders from a
financial point of view. A copy of the Fairness Opinion, which sets forth
certain assumptions made, matters considered and limitations on the review
undertaken, is attached as Appendix C to this Prospectus and should be read in
its entirety. The summary of the Fairness Opinion set forth herein is qualified
in its entirety by reference to the text of the Fairness Opinion.
 
     In addition to rendering the Fairness Opinion, Advisor was engaged to
develop a bid package and to preside over the bidding process on behalf of
Bankshares.
 
     In arriving at its Fairness Opinion, Advisor performed merger analyses
described below. Advisor also reviewed certain publicly available business and
financial information relating to Bankshares and BancGroup. Advisor also
considered certain financial and stock market data of Bankshares and BancGroup,
compared that data with similar data for certain other publicly held banks and
bank holding companies in the Southeastern United States and considered the
financial terms of certain other recent comparable community bank acquisition
transactions in three southeastern states, as further discussed below. Advisor
also considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria that it deemed
relevant. In connection with its review, Advisor did not independently verify
the foregoing information and relied on such information as being complete and
accurate in all material respects. Financial forecasts prepared by Bankshares
management and submitted to Advisor were based on assumptions believed by
Advisor to be reasonable and to reflect currently available information, but
Advisor did not independently verify such information. Advisor did not make an
independent evaluation or appraisal of the assets of Bankshares or BancGroup.
 
     In connection with rendering the Fairness Opinion, Advisor performed a
variety of financial analyses, including those summarized below. The summary set
forth below does not purport to be a complete description of the analyses
performed by Advisor in this regard. The preparation of a fairness opinion
involves various determinations as to the most appropriate and relevant methods
of financial analysis and the application of these methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Accordingly, notwithstanding the separate factors
summarized below, Advisor believes that its analyses must be considered as a
whole and that selecting portions of its analyses and the factors considered by
it, without considering all analyses and factors, could create an incomplete
view of the evaluation process underlying its opinion. In performing its
analyses, Advisor made numerous assumptions with respect to industry
performance, business and economic conditions and other matters, many of which
are beyond Bankshares' or BancGroup's control. The analyses performed by Advisor
are not necessarily indicative

of actual values or future results, which may be significantly more or less
favorable than suggested by such analyses. No company or transaction considered
as a comparison in the analyses is identical to Bankshares, BancGroup or the
Merger. Accordingly, an analysis of the results of such comparisons is not
mathematical; rather, it involves complex considerations and judgments
concerning differences in financial and operating characteristics of companies
and other factors that could affect the public trading value of the companies
involved in such comparisons. In addition, the analyses do not purport to be
appraisals or reflect the process by which or the prices at which businesses
actually may be sold or the prices at which any securities may trade at the
present time or at any time in the future.
 
     Merger Analysis.  The merger consideration to be received by Bankshares
shareholders is set at $27.39. Advisor reviewed the terms of the Agreement and
determined that the Market Value of BancGroup Common Stock to be used for
setting the exchange ratio continues to be appropriate ranging from $29.75 per
share to $37.75 per share. BancGroup's Common Stock trades on the New York Stock
Exchange and closed at $35.00 per share on October 17, 1996. Average daily
volume for 1996 year-to-date is estimated at 8,500 shares. The current dividend
yield is 3.09%.
 
     Comparable Transactions Analysis.  Advisor reviewed the Merger as of
October 11, 1996, for the purpose of determining purchase premiums which could
be used in comparing the Merger with other announced transactions. Advisor
reviewed the purchase premiums paid in 74 transactions that were announced
between July 1, 1995 and October 11, 1996 involving selling institutions
headquartered in the state of Alabama, Florida, Georgia and Tennessee. Of these
transactions, nine involved selling institutions that have been determined to be
comparable transactions. They include institutions representing commercial banks
with total assets between $100 million and $200 million. The purchase premiums
in the Merger rank within the range of purchase premiums paid in the comparable
transactions. On average, the nine comparable transactions reported an announced
deal price to book value of 1.646 times and an announced deal price to earnings
of 14.36 times. A listing of the comparable transactions is included in the
following table.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF BANKSHARES
 
     The Board of Directors of Bankshares has determined that the Merger is in
the best interests of Bankshares and its shareholders. THE BOARD OF DIRECTORS
UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF BANKSHARES VOTE IN FAVOR OF THE
APPROVAL AND ADOPTION OF THE MERGER AND THE AGREEMENT.
 
BANCGROUP'S REASONS FOR THE MERGER
 
     The Board of Directors of BancGroup has unanimously approved the Merger and
the Agreement. BancGroup has been seeking to expand its banking service in the
Georgia market and currently operates a commercial bank and a federal savings
bank in the Atlanta area. The Board of Directors of BancGroup believes that the
acquisition of Bankshares and the Bank is consistent with that strategy.
 
     In approving the Merger and the Agreement, the Board of Directors of
BancGroup took into account: (i) the financial performance and condition of
Bankshares, including its strong capital and good asset quality; (ii)
similarities in the philosophies of BancGroup and Bankshares, including
Bankshares' commitment to delivering high quality personalized financial
services to its customers; and (iii) Bankshares' management's knowledge of and
experience in the Northwest Georgia area.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain directors and executive officers of Bankshares hold Bankshares
Options which entitle them to purchase, in the aggregate, up to 46,750 shares of
Bankshares Common Stock. Under the terms of the Agreement, any Bankshares
Options which are not exercised prior to the Effective Date will be assumed by
BancGroup giving the holders of such options the right to acquire shares of
BancGroup Common Stock. See "Conversion of Bankshares Common Stock."
 
     Certain of the directors and executive officers of Bankshares own Series A
Debentures which are convertible into, in the aggregate, up to 15,906 shares of
Bankshares Common Stock. Under the terms of the Agreement, any Series A
Debentures which are not converted prior to the Effective Date will be assumed
by BancGroup. See "The Merger -- Conversion of Bankshares Common Stock" and
"Treatment of Series A Debentures."
 
     The Agreement provides that it is a condition to BancGroup's obligation to
close the Merger that Charles Y. Allgood, president of Bankshares and the Bank,
execute a severance agreement with BancGroup. Mr. Allgood and BancGroup have
agreed upon the terms of the severance agreement which will provide that (i) for
a period of one year following the Effective Date, BancGroup may terminate Mr.
Allgood's employment at any time by paying Mr. Allgood a lump-sum payment equal
to Mr. Allgood's annual cash
 
                                       15
<PAGE>   27
 
salary at the time the notice of termination is given plus $12,300; (ii)
BancGroup's obligation to make the payments referenced in the foregoing clause
(i) shall not apply if BancGroup terminates Mr. Allgood for "cause", as defined
in the severance agreement, or if Mr. Allgood voluntarily terminates his
employment; and (iii) Mr. Allgood will agree not to compete with the Bank in
Whitfield County for a period of 12 months following his termination provided he
has received the lump-sum payment referenced in clause (i) above or one-half of
such payment if Mr. Allgood is terminated for cause or voluntarily terminates
his employment.
 
     On the Effective Date, all employees of Bankshares (including its executive
officers) shall, at BancGroup's option, either become employees of BancGroup or
its subsidiaries or be entitled to severance benefits in accordance with
BancGroup's severance policy as of the date of the Agreement. All employees of
Bankshares who become employees of BancGroup or its subsidiaries on the
Effective Date shall be entitled, to the extent permitted by applicable law, to
participate in all benefit plans of BancGroup to the same extent as BancGroup's
employees. BancGroup has indicated that it currently intends to retain each of
the executive officers of Bankshares following the consummation of the Merger
(although it has no obligation to do so), on substantially the same terms and
conditions (including salary) as currently earned by such executive officers.
 
     Under the Agreement, BancGroup has agreed to indemnify the directors and
executive officers of Bankshares against certain claims and liabilities arising
out of or pertaining to matters existing or occurring at or prior to the
Effective Date, to the fullest extent that Bankshares would have been permitted
under Georgia law, or under its Articles of Incorporation or Bylaws, to
indemnify such persons (and also to advance expenses as incurred to the fullest
extent permitted under applicable law).
 
     Except as described above, none of the directors or executive officers of
Bankshares, and no associate of any such person, has any substantial direct or
indirect interest in the Merger, other than an interest arising from the
ownership of Bankshares Common Stock.
 
CONVERSION OF BANKSHARES COMMON STOCK
 
     On the Effective Date, each share of Bankshares Common Stock outstanding
and held by Bankshares' shareholders shall be converted by operation of law and
without any action by any holder thereof into shares of BancGroup Common Stock
(the "Merger Consideration"). Specifically, each outstanding share of Bankshares
Common Stock shall be converted into a number of shares of BancGroup Common
Stock which is equal to $27.39 divided 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 trading days ending on the trading day immediately preceding the Effective
Date, provided, however, that regardless of the actual Market Value as
calculated above, Market Value shall not be less than $29.75, nor more than
$37.75. Accordingly, the maximum number of shares of BancGroup Common Stock to
be issued in the Merger shall be 645,240 (based upon a minimum Market Value of
$29.75) and the minimum number of shares of BancGroup Common Stock to be issued
in the Merger shall be 508,500 (based upon a maximum Market Value of $37.75)
assuming 700,836 shares of Bankshares Common Stock outstanding.
 
     To the extent that the number of shares of Bankshares Common Stock may
increase based upon the exercise of Bankshares Options or the conversion of the
Series A Debentures, the aggregate number of shares of BancGroup Common Stock to
be issued in the Merger shall be increased with each share of Bankshares Common
Stock outstanding at the Effective Date being exchanged for a number of shares
of BancGroup Common Stock which is equal to one share of Bankshares Common Stock
multiplied by the Exchange Ratio, i.e., $27.39 divided by the Market Value.
 
     No fractional shares of BancGroup Common Stock will be issued in connection
with the Merger. Each shareholder of Bankshares having a fractional interest
arising upon the conversion of Bankshares Common Stock into BancGroup Common
Stock will, at the time of surrender of the certificates representing Bankshares
Common Stock, be paid by BancGroup an amount of cash equal to the value of such
fractional interest based on the fair market value of such fractional share.
Fair market value for this purpose shall be the Market Value.

     As an example, a shareholder of Bankshares who owns 100 shares of
Bankshares Common Stock would be entitled to receive for such shares BancGroup
Common Stock. Assuming a Market Value of BancGroup Common Stock at the Merger of
$35.05 (calculated as of September 19, 1996), then such shareholder would
receive Merger Consideration as follows:

    <S>                                                          <C>

</TABLE>
 
- ---------------
 
(1) Each share of Bankshares Common Stock receives an amount of BancGroup Common
     Stock determined by the following formula: $27.39  / $35.05 = 0.7815. Thus,
     100 shares multiplied by 0.7815 yields 78 shares of BancGroup Common Stock.
     The fraction of .15 of a share would be paid in cash.
 
     As the Market Value of the BancGroup Common Stock rises, the number of
shares of BancGroup Common Stock to be issued in the Merger will decrease, and
as the Market Value falls, the number of such shares will increase, subject to
the minimum and maximum shares to be issued as described above.
 
     The Agreement provides that if, prior to the Effective Date, BancGroup
Common Stock shall be changed into a different number of shares or a different
class of shares by reason of any recapitalization or reclassification, stock
dividend, combination, stock split, or reverse stock split of the BancGroup
Common Stock, an appropriate and proportionate adjustment shall be made in the
number of shares of BancGroup Common Stock into which the Bankshares Common
Stock shall be converted in the Merger.
 
     On the Effective Date, BancGroup will assume Bankshares' Series A
Debentures respecting the issuance of 64,773 shares of Bankshares Common Stock.
Such debentures shall be convertible into shares of BancGroup Common Stock, with
each share of Bankshares Common Stock that would have been issued upon
conversion of such debenture being convertible into a number of shares of
BancGroup Common Stock which is equal to one share of Bankshares Common Stock
multiplied by the Exchange Ratio -- i.e., $27.39 divided by the Market Value. No
fractions of shares of BancGroup Common Stock will be issued upon conversion of
such debentures, and any fractions to be issued shall be paid in cash, as set
forth in such debentures.
 
     BancGroup will also assume the Bankshares Options outstanding on the
Effective Date. For a description of the assumption of such options, see
"Treatment of Bankshares Options."
 
SURRENDER OF BANKSHARES COMMON STOCK CERTIFICATES
 
     Upon the Effective Date and subject to the conditions described at
"Conditions to Consummation of the Merger," Bankshares' shareholders will
automatically, and without further action by such shareholders or by BancGroup,
become owners of BancGroup Common Stock as described herein. Outstanding
certificates representing shares of the Bankshares Common Stock shall represent
shares of BancGroup Common Stock. Thereafter, upon surrender of the certificates
formerly representing shares of Bankshares Common Stock, the holders will be
entitled to receive certificates for the BancGroup Common Stock. Dividends on
the shares of BancGroup Common Stock will accumulate without interest and will
not be distributed to any former shareholder of Bankshares unless and until such
shareholder surrenders for cancellation his or her certificate for Bankshares
Common Stock. SunTrust Bank, Atlanta, Georgia, transfer agent for BancGroup
Common Stock, will act as the Exchange Agent with respect to the shares of
Bankshares Common Stock surrendered in connection with the Merger.
 
     A detailed explanation of these arrangements will be mailed to Bankshares
shareholders promptly following the Effective Date. STOCK CERTIFICATES SHOULD
NOT BE SENT TO THE EXCHANGE AGENT UNTIL SUCH NOTICE IS RECEIVED.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The Merger is intended to qualify as a "reorganization" for federal income
tax purposes under Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as
amended (the "Code"). The obligation of Bankshares and BancGroup to consummate
the Merger is conditioned on the receipt by Bankshares and
 
                                       17
<PAGE>   29
 
BancGroup of an opinion from Miller, Hamilton, Snider & Odom, L.L.C., counsel to
BancGroup, to the effect that the Merger will constitute such a reorganization.
The opinion has been delivered to Bankshares and BancGroup. In delivering its
opinion, Miller, Hamilton, Snider & Odom, L.L.C., have received and relied upon
certain representations of BancGroup and Bankshares and certain other
information, data, documentation and other materials as it deems necessary. The
tax opinion is based upon certain assumptions, including the assumption that
Bankshares has no knowledge of any plan or intention on the part of the
Bankshares shareholders to sell or dispose of BancGroup Common Stock that would
reduce their holdings to a number of shares having in the aggregate a fair
market value of less than 50% of the total fair market value of the Bankshares
Common Stock outstanding immediately upon the Merger.
 
     Neither Bankshares nor BancGroup intends to seek a ruling from the Internal
Revenue Service as to the federal income tax consequences of the Merger.
Bankshares' shareholders should be aware that the opinion of counsel will not be
binding on the Internal Revenue Service or the courts.
 
     Among other things, the following discussion is based on Bankshares'
shareholders maintaining sufficient equity ownership interest in BancGroup after
the Merger. The Internal Revenue Service takes the position for purposes of
issuing an advance ruling on reorganizations that the shareholders of an
acquired corporation (i.e., Bankshares) must maintain, in the aggregate, a
continuing equity ownership interest in the acquiring corporation (i.e.,
BancGroup) equal, in terms of value, to at least 50% of their interest in such
acquired corporation. Shares of Bankshares Common Stock and BancGroup Common
Stock held by Bankshares shareholders and otherwise sold, redeemed or disposed
of prior or subsequent to the Merger may be taken into account in determining
whether the requirement with respect to continuing equity ownership of BancGroup
Common Stock is met by Bankshares' shareholders.
 
     If the assumption stated above, that there is no plan or intention by the
Bankshares shareholders to sell or dispose of BancGroup Common Stock that would
reduce their holdings to a number of shares with an aggregate fair market value
of at least 50 percent of the total fair market value of Bankshares Common Stock
outstanding immediately before the Merger, were to be incorrect, then counsel
could not opine that the Merger is a reorganization under Section 368 of the
Code.
 
     The tax opinion states that, provided the assumptions stated therein are
satisfied, the following federal income tax consequences will result to
Bankshares' shareholders who exchange their shares of Bankshares Common Stock
for shares of BancGroup Common Stock:
 
          1. The Merger will qualify as a reorganization within the meaning of
     Section 368(a)(1) pursuant to Section 368(a)(1)(A) of the Code.
 
          2. No gain or loss will be recognized by Bankshares upon the transfer
     of its assets and liabilities to BancGroup. No gain or loss will be
     recognized by BancGroup upon the receipt of the assets and liabilities of
     Bankshares.
 
          3. The basis of the assets of Bankshares acquired by BancGroup will be
     the same as the basis of the assets in the hands of Bankshares immediately
     prior to the Merger.
 
          4. The holding period of the assets of Bankshares in the hands of
     BancGroup will include the period during which such assets were held by
     Bankshares.
 
          5. No gain or loss will be recognized by a Bankshares shareholder upon
     the receipt of BancGroup Common Stock solely in exchange for such
     shareholder's Bankshares' Common Stock; except that gain or loss resulting
     from the receipt of cash by Bankshares' shareholders who dissent will be
     recognized in accordance with the provisions of Section 302 of the Code as
     a distribution in redemption of such shareholder's Bankshares Common Stock.
     In addition, no gain or loss will be recognized by a Bankshares debenture
     holder upon the assumption of such debentures by BancGroup.
 
          6. The payment of cash to a Bankshares shareholder 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 shareholder and
     then redeemed by BancGroup, with the tax effect of such deemed redemption
     being determined under Section 302(b) of the Code.
 
                                       18
<PAGE>   30
 
          7. The basis of the BancGroup Common Stock (including any fractional
     share) received by a Bankshares shareholder in the Merger will be the same
     as the basis of the Bankshares 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.
 
          8. The holding period of the BancGroup Common Stock received by a
     Bankshares shareholder in the Merger will include the holding period of the
     Bankshares Common Stock surrendered in exchange therefor, provided such
     shares of Bankshares Common Stock were capital assets or property described
     under Section 1231 of the Code in the hands of a Bankshares shareholder on
     the day of the Merger, and otherwise will begin on the date following the
     date of the Merger.
 
     THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF ALL MATERIAL
FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO THE SHAREHOLDERS OF BANKSHARES,
TO BANKSHARES AND TO BANCGROUP AND DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
LISTING OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A DECISION WHETHER TO VOTE IN
FAVOR OF APPROVAL OF THE MERGER. THE DISCUSSION DOES NOT ADDRESS THE TAX
CONSEQUENCES THAT MAY BE RELEVANT TO A PARTICULAR SHAREHOLDER SUBJECT TO SPECIAL
TREATMENT UNDER CERTAIN FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES,
BANKS, INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS, NON-UNITED STATES PERSONS,
SHAREHOLDERS WHO DO NOT HOLD THEIR SHARES OF BANKSHARES COMMON STOCK AS "CAPITAL
ASSETS" WITHIN THE MEANING OF SECTION 1221 OF THE CODE, AND SHAREHOLDERS WHO
ACQUIRED THEIR SHARES OF BANKSHARES COMMON STOCK PURSUANT TO THE EXERCISE OF
OPTIONS OR OTHERWISE AS COMPENSATION, NOR ANY CONSEQUENCES ARISING UNDER THE

and privileges attaching to Bankshares Common Stock as compared with BancGroup
Common Stock, see "COMPARATIVE RIGHTS OF STOCKHOLDERS."
 
CONDITIONS TO CONSUMMATION OF THE MERGER
 
     The parties' obligation to consummate the Merger is subject to the
satisfaction (or waiver, to the extent permitted by law) of various conditions
set forth in the Agreement.
 
     The obligations of Bankshares and BancGroup to consummate the Merger are
conditioned upon, among other things, (i) the approval of the Agreement by the
holders of at least a majority of the outstanding shares of Bankshares Common
Stock; (ii) any required approvals of the Merger by the Federal Reserve and the
Georgia Department, and the approval of the merger of the Bank with Colonial
Bank by the FDIC and the Georgia Department; (iii) the absence of pending or
threatened litigation with a view to restraining or prohibiting consummation of
the Merger or in which it is sought to obtain divestiture, rescission or damages
in
 
                                       19
<PAGE>   31
 
connection with the Merger, (iv) the absence of any investigation by any
governmental agency which might result in any such proceeding, (v) consummation
of the Merger no later than May 31, 1997, and (vi) receipt of opinions of
counsel regarding certain matters.
 
     The obligation of Bankshares to consummate the Merger is further subject to
several other conditions, including: (i) the absence of any material adverse
change in the financial condition or affairs of BancGroup; (ii) the shares of
BancGroup Common Stock to be issued under the Agreement having been approved for
listing on the NYSE; (iii) the accuracy in all material respects of the
representations and warranties of BancGroup contained in the Agreement and the
performance by BancGroup of all of its covenants and agreements under the
Agreement; and (iv) receipt of the opinion of the Advisor that the Merger
Consideration is fair from a financial point of view to the shareholders of
Bankshares.
 
     The obligation of BancGroup to consummate the Merger is subject to several
other conditions, including: (i) the absence of any material adverse change in
the financial condition or affairs of Bankshares; (ii) the accuracy in all
material respects of the representations and warranties of Bankshares contained
in the Agreement, and the performance by Bankshares of all of its covenants and
agreements under the Agreement; (iii) the receipt by BancGroup of certain
undertakings from holders of Bankshares Common Stock who may be deemed to be
"affiliates" of Bankshares pursuant to the rules of the Commission; and (iv) the
receipt of an opinion from Coopers & Lybrand L.L.P. that the Merger qualifies
for pooling of interests accounting treatment.
 
     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, will be satisfied.
The Agreement provides that Bankshares and BancGroup may waive all conditions to
their obligations to consummate the Merger, other than the receipt of the
requisite approvals of regulatory authorities and Bankshares shareholder
approval of the Merger. In making any decision regarding a waiver of one or more
conditions to consummation of the Merger or an amendment of the Agreement, the
Boards of Directors of Bankshares and BancGroup would be subject to fiduciary
duty standards imposed upon such boards by relevant law that would require such
boards to act in the best interests of their respective shareholders.
 
AMENDMENT OR TERMINATION
 
     The Boards of Directors of BancGroup and Bankshares may agree to amend or
terminate the Agreement before or after approval by the shareholders of
Bankshares. However, the Board of Directors of Bankshares shall not agree to any
amendments to the Agreement which would alter the Merger Consideration or which
in the opinion of the Board of Directors of Bankshares would adversely affect
the rights of the shareholders of Bankshares, unless such amendments are
approved by the holders of a majority of the outstanding Bankshares Common
Stock. Such amendments may require the filing of an amendment of the
Registration Statement, of which this Prospectus forms a part, with the
Commission. See "Conditions to Consummation of the Merger."
 
REGULATORY APPROVALS
 
     Prior to the Merger, a 30-day prior notification to the Federal Reserve
will be provided pursuant to Section 3 of the BHCA and the regulations
promulgated pursuant thereto. Approval of the Georgia Department under the
Financial Institutions Code of Georgia must also be obtained. It is contemplated
that the Merger will occur simultaneously with the merger of the Bank with and
into BancGroup's wholly-owned subsidiary Colonial Bank, Lawrenceville, Georgia
(the "Bank Merger"). The approval of the FDIC and the Georgia Department must be
obtained prior to the Bank Merger. It is anticipated that BancGroup will file
the notification with the Federal Reserve and the applications with the FDIC and
the Georgia Department on or about        , 1996, and the regulatory approval
process is expected to take approximately three months from that date.
 
     Federal Reserve Notification.  Under limited circumstances, approval of the
Merger by the Federal Reserve under Section 3 of the BHCA is not required. More
specifically, the Merger would not require Federal Reserve approval if: (1) the
Bank is merged into a BancGroup bank subsidiary simultaneously with
 
                                       20
<PAGE>   32
 
the Merger; (2) the Bank's merger into a BancGroup bank subsidiary requires the
prior approval of a federal supervisory agency under the Bank Merger Act; (3)
the transaction does not involve an acquisition subject to Section 4 of the
BHCA; (4) both before and after the transaction, BancGroup meets the Federal
Reserve's capital adequacy guidelines; and (5) BancGroup provides written notice
of the transaction to the Federal Reserve at least thirty days prior to the
transaction, and during that period, the Federal Reserve does not require an
application under Section 3 of the Bank Holding Company Act. It is anticipated
that BancGroup will satisfy the foregoing requirements, and, absent Federal
Reserve action pursuant to item 5 above, an application with the Federal Reserve
will not be required.
 
     In the event the Federal Reserve requires an application pursuant to
Section 3 of the BHCA, approval of the Federal Reserve would be required prior
to the Merger. Pursuant to Section 3 of the BHCA, and the regulations
promulgated pursuant thereto, the Federal Reserve must withhold approval of the
Merger if it finds that the transaction will result in a monopoly or be in
furtherance of any combination or conspiracy to monopolize or attempt to
monopolize the business of banking in any part of the United States. In
addition, the Federal Reserve may not approve the Merger if it finds that the
effect thereof may be substantially to lessen competition in any section of the
country, or tend to create a monopoly, or would in any other manner be in
restraint of trade, unless it finds that the anti-competitive effects of the
Merger are clearly outweighed by the probable effect of the Merger in meeting
the convenience and needs of the communities to be served. The Federal Reserve
will also take into consideration the financial condition and managerial
resources of BancGroup, its subsidiaries, any banks related to BancGroup through
common ownership or management, and the Bank. Finally, the Federal Reserve will
consider the compliance records of BancGroup's subsidiaries under the Community
Reinvestment Act.
 
     The BHCA provides for the publication of notice and public comment on the
application and authorizes the Federal Reserve to permit interested parties to
intervene in the proceedings. If an interested party is permitted to intervene,
such intervention could delay the regulatory approvals required for consummation
of the Merger. Section 11 of the BHCA imposes a waiting period which prohibits
the consummation of the Merger, in ordinary circumstances, for a period ranging
from 15-30 days following the Federal Reserve's approval of the Merger. During
such period, the U.S. Department of Justice, should it object to the Merger for
antitrust reasons, may challenge the consummation of the Merger.
 
     Georgia Department.  The Georgia Department must also approve the Merger
and the Bank Merger pursuant to applicable provisions of the Financial
Institutions Code of Georgia. The Commissioner of the Georgia Department is
prohibited from approving the Merger if it would result in a monopoly or be in
furtherance of any combination or conspiracy to monopolize or attempt to
monopolize the business of banking in any part of the state of Georgia. In
addition, the Commissioner is prohibited from approving the Merger if it
determines that the effect of the Merger, in any section of the state, would be
substantially to lessen competition, or tend to create a monopoly, or which in
any other manner would be in restraint of trade, unless it finds that the
anti-competitive effects of the proposed transaction are clearly outweighed in
the public interests by the probable effect of the transaction in meeting the
convenience and needs of the community to be served. As part of the Georgia
Department's review of the Merger, the Commissioner is required to take into
consideration the financial and managerial resources and future prospects of the
company or companies and the banks concerned and the convenience and needs of
the community to be served. Prior to granting approval, the Commissioner is
required to provide reasonable notice of the Merger in the area affected and
afford the public an opportunity to submit information, objections, and opinions
of the Merger for the Commissioner's consideration.
 
     Prior to approving the Bank Merger, the Georgia Department must determine
that the applicable requirements of the Financial Institutions Code of Georgia
have been satisfied, that the plan of merger and any modification thereof
adequately protect the interests of depositors, other creditors, and
shareholders, that the requirements for the Bank Merger under all applicable
laws have been satisfied and the resulting bank would satisfy the requirements
of the Financial Institutions Code of Georgia applicable to it, and the Bank
Merger would be consistent with adequate and sound banking or fiduciary practice
and in the public interest on the basis of the financial history and condition
of the parties to the plan of merger, their prospects, the
 
                                       21
<PAGE>   33
 
character of their management, and the convenience and needs of the area
primarily to be served by the resulting institution.
 
     Federal Deposit Insurance Corporation.  Pursuant to the requirements of the
Federal Deposit Insurance Act, the FDIC must approve the Bank Merger. The FDIC
is prohibited from approving the Bank Merger if it would result in a monopoly or
would be in furtherance of any combination or conspiracy to monopolize or to
attempt to monopolize the business of banking in any part of the United States.
In addition, the FDIC is prohibited from approving the Bank Merger if its
effect, in any section of the country, would be substantially to lessen
competition, or to tend to create a monopoly, or which in any other manner would
be in restraint of trade, unless it finds that the anti-competitive effects of
the Bank Merger are clearly outweighed in the public interest by the probable
effect of the Bank Merger in meeting the convenience and needs of the community
to be served. The FDIC is required to take into consideration the financial and
managerial resources and future prospects of the existing and proposed
institutions, and the convenience and needs of the community to be served.
 
     The Bank Merger Act imposes a waiting period which prohibits consummation
of the Bank Merger, in ordinary circumstances, for a period ranging from 15-30
days following the FDIC's approval of the Bank Merger. During such period, the
United States Department of Justice, should it object to the Bank Merger for
antitrust reasons, may challenge the consummation of the Bank Merger.
 
     The Agreement provides that the obligation of each of BancGroup and
Bankshares to consummate the Merger is conditioned upon the receipt of all
necessary regulatory approvals. There can be no assurance that any regulatory
agency will approve BancGroup's applications to acquire Bankshares, and, if such
approvals are received, that such approvals will not be conditioned upon terms
and conditions that would cause the parties to abandon the Merger.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
     The Agreement contains certain restrictions on the conduct of the business
of Bankshares pending consummation of the Merger. The Agreement prohibits
Bankshares from taking any of the following actions, prior to the Effective
Date, subject to certain limited exceptions previously agreed to by the parties,
without the prior written approval of BancGroup:
 
          (i) Issuing, delivering or agreeing to issue or deliver any stock,
     bonds or other corporate securities (whether authorized and unissued or
     held in the treasury), except shares of Bankshares Common Stock issued upon
     the exercise of Bankshares Options or the conversion of the Series A
     Debentures;
 
          (ii) Borrowing or agreeing to borrow any funds or incurring or
     becoming subject to, any liability (absolute or contingent) except
     borrowings, obligations and liabilities incurred in the ordinary course of
     business and consistent with past practice;
 
          (iii) Paying any material obligation or liability (absolute or
     contingent) other than current liabilities reflected in or shown on the
     most recent balance sheet and current liabilities incurred since that date
     in the ordinary course of business and consistent with past practice;
 
          (iv) Declaring or making or agreeing to declare or make, any payment
     of dividends or distributions of any assets of any kind whatsoever to
     shareholders, or purchasing or redeeming or agreeing to purchase or redeem,
     any of its outstanding securities;
 
          (v) Except in the ordinary course of business, selling or transferring
     or agreeing to sell or transfer, any of its assets, or canceling, or
     agreeing to cancel, any debts or claims;
 
          (vi) Except in the ordinary course of business, entering or agreeing
     to enter into any agreement or arrangement granting any preferential rights
     to purchase any of its assets, or requiring the consent of any party to the
     transfer and assignment of any of its assets;
 
          (vii) Suffering any losses or waiving any rights of value which in the
     aggregate are material;
 
                                       22
<PAGE>   34
 
          (viii) Except in the ordinary course of business, making or permitting
     any amendment or termination of any contract, agreement or license to which
     it is a party if such amendment or termination is material considering its
     business as a whole;
 
          (ix) Except in accordance with normal and usual practice, making any
     accrual or arrangement for or payment of bonuses or special compensation of
     any kind or any severance or termination pay to any present or former
     officer or employee;
 
          (x) Except in accordance with normal and usual practice, increasing
     the rate of compensation payable to or to become payable to any of its
     officers or employees or making any material increase in any
     profit-sharing, bonus, deferred compensation, savings, insurance, pension,
     retirement or other employee benefit plan, payment or arrangement made to,
     for or with any of its officers or employees;
 
          (xi) Failing to operate its business in the ordinary course so as to
     preserve its business intact and to preserve the goodwill of its customers
     and others with whom it has business relations; and
 
          (xii) Entering into any other material transaction other than in the
     ordinary course of business.
 
     The Agreement provides that prior to the Effective Date, no director or
officer (vice president and above) of Bankshares or any of its subsidiaries
shall, directly or indirectly own, manage, operate, join, control, be employed
by or participate in the ownership, proposed ownership, management, operation or
control of or be connected in any manner with, any business, corporation or
partnership which is competitive to the business of Bankshares or its
subsidiaries.
 
     The Agreement also provides that, at the request of BancGroup, (i)
Bankshares will inform BancGroup concerning loan requests over $250,000 that are
not single-family residential loans and other loan requests outside the ordinary
course of business and (ii) Bankshares will consult with BancGroup to coordinate
various other business issues on a basis mutually satisfactory to Bankshares and
BancGroup. Bankshares and the Bank shall not be required to undertake any of
such activities, however, except as such activities may be in compliance with
existing law.
 
COMMITMENTS WITH RESPECT TO OTHER OFFERS
 
     Until the termination of the Agreement, neither Bankshares 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, Bankshares or any
business combination involving Bankshares other than as contemplated by the
Agreement. Bankshares will notify BancGroup immediately if any such inquiries or
proposals are received by Bankshares, if any such information is requested from
Bankshares, or if any such negotiations or discussions are sought to be
initiated with Bankshares. Bankshares shall instruct its officers, directors,
agents or affiliates or their subsidiaries to refrain from doing any of the
above; provided, however, that Bankshares may communicate information about any
such acquisition proposal to its shareholders if and to the extent that legal
counsel provides a written opinion to Bankshares that it is required to do so in
order to comply with its legal obligations.
 
INDEMNIFICATION
 
     BancGroup has agreed to indemnify present and former directors and officers
of Bankshares and the Bank against liabilities arising out of actions or
omissions occurring at or prior to the Effective Date to the extent provided
under Georgia law and Bankshares' Articles of Incorporation and Bylaws.
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
     Article 13 of the Georgia Business Corporation Code provides for rights of
appraisal for the value of the shares of a shareholder who (i) has delivered
notice in writing to Bankshares before the vote is taken that the stockholder
intends to demand payment for his or her shares if the Merger is consummated and
(ii) either votes against the Merger or refrains from voting on the Merger. The
notice must be delivered to D/W Bankshares, Inc., attention Corporate Secretary,
401 South Thornton Avenue, Dalton, Georgia 30720. If a shareholder votes against
the Merger or refrains from voting on the Merger, but does not also deliver the
 
                                       23
<PAGE>   35
 
notice in writing to Bankshares before the shareholder vote on the Merger
occurs, such shareholder will lose his or her appraisal rights.
 
     Within ten (10) days after the Effective Date of the Merger, BancGroup, as
the corporation surviving the Merger, will send to each Bankshares shareholder
who has given such notice a written dissenter's notice (the "Dissenter's
Notice") stating, among other things, a date not less than thirty (30) days nor
more than sixty (60) days after the date of the Dissenter's Notice by which the
shareholder must submit a written payment demand. The Dissenter's Notice will
also include where and when stock certificates for shares of Bankshares Common
Stock must be deposited. A Bankshares shareholder who does not demand payment or
deposit stock certificates where required by the date set in the Dissenter's
Notice shall lose his or her right to dissent and will not be entitled to
payment for his or her shares.
 
     Within ten (10) days of the later of the Effective Date or receipt of a
payment demand by the dissenting shareholders, BancGroup will offer to pay each
dissenting shareholder who has complied with the requirements of the Georgia
Business Corporation Code the amount which BancGroup estimates to be the fair
value of the shares, plus accrued interest. A shareholder may agree to accept
such offer.
 
     If a dissenting shareholder is dissatisfied with BancGroup's offer of
payment, the shareholder may notify BancGroup in writing within thirty (30) days
of the offer of his or her own estimate of the fair value plus interest and
demand that such payment be made. A dissenting shareholder waives his or her
right to demand payment of a different amount than that offered by BancGroup and
is deemed to have accepted BancGroup's offer unless such written notification is
provided to BancGroup within such period.
 
     In the event a dissenting shareholder's second payment demand remains
unsettled within sixty (60) days after BancGroup receives such demand, BancGroup
will commence a nonjury equitable valuation proceeding in the Whitfield County
Superior Court to determine the fair value of the shares and accrued interest.
BancGroup will make all dissenting shareholders whose second payment demand
remains unsettled parties to the court proceeding. In the proceeding, the court
will fix a value of the shares and may appoint one or more appraisers to receive
evidence and recommend a decision on the question of fair value. If BancGroup
does not commence the proceeding within sixty (60) days after receiving the
dissenting shareholder's second payment demand, BancGroup shall pay each
dissenting shareholder whose second payment demand remains unsettled the amount
demanded by each such dissenting shareholder in his or her second payment
demand.
 
     The determination of a "fair value" necessarily involves matters of
judgment upon which reasonable persons may disagree. No allowance is permitted
for any increase or decrease in the value of the Bankshares Common Stock which
may be attributed to the proposed Merger.
 
     A record shareholder may assert dissenters' rights as to fewer than all
shares registered in such holder's name, but only if the record holder dissents
with respect to all shares beneficially owned by any one beneficial shareholder
and provides written notice to Bankshares of the name and address of each person
on whose behalf the dissenting rights are asserted. A "beneficial shareholder"
is defined in the Georgia Business Corporation Code as a "person who is a
beneficial owner of shares held in a voting trust or by a nominee as the record
shareholder." The rights of a partial dissenter are determined as if the shares
as to which such holder dissents and other shares held by the holder are
registered in different names of shareholders. Thus, if a beneficial shareholder
holds shares of Bankshares Common Stock through a bank, broker, or other
nominee, such beneficial holder may assert dissenters' rights, but only if the
nominee dissents with respect to all shares beneficially owned by such
shareholder through the bank, broker or nominee and provides Bankshares with the
name and address of each such person wishing to assert dissenters' rights. A
person holding Bankshares Common Stock through a bank, broker or other nominee
should act promptly to cause such bank, broker or nominee to follow the proper
procedures to perfect any dissenters' rights on behalf of such person.
 
     A dissenting shareholder may not challenge the Merger unless Bankshares
fails to comply with appropriate procedures under Georgia law or Bankshares'
Articles of Incorporation and Bylaws or unless the shareholder vote to approve
the Merger was obtained by fraudulent and deceptive means.
 
     FAILURE OF A SHAREHOLDER TO COMPLY WITH ANY REQUIREMENTS OF THE PROVISIONS
RELATING TO DISSENTER'S RIGHTS OF APPRAISAL WILL RESULT IN A FORFEITURE BY SUCH
SHAREHOLDER OF APPRAISAL RIGHTS. ANY HOLDER OF BANKSHARES

COMMON STOCK WHO DESIRES TO EXERCISE DISSENTERS' RIGHTS IS URGED TO CONSULT A
LEGAL ADVISOR BEFORE ATTEMPTING TO EXERCISE SUCH RIGHTS.
 
     References herein to applicable statutes are summaries of portions thereof
and do not purport to be complete and are qualified in their entirety by
reference to applicable law. Article 13 of the Georgia Business Corporation Code
is attached hereto as Appendix B. SHAREHOLDERS SHOULD READ APPENDIX B CAREFULLY.
 
RESALE OF BANCGROUP COMMON STOCK ISSUED IN THE MERGER
 
     The issuance of the shares of BancGroup Common Stock pursuant to the Merger
(including any shares to be issued pursuant to Bankshares Options) has been
registered under the Securities Act of 1933 (the "Securities Act"). As a result,
shareholders of Bankshares who are not "affiliates" of Bankshares (as such term
is defined under the Securities Act) may resell, without restriction, all shares
of BancGroup Common Stock which they receive in connection with the Merger.
Under the Securities Act, affiliates of Bankshares are subject to restrictions
on the resale of the BancGroup Common Stock which they receive in the Merger.
 
     The BancGroup Common Stock received by affiliates of Bankshares who do not
also become affiliates of BancGroup after the consummation of the Merger may not
be sold except pursuant to an effective Registration Statement under the
Securities Act covering such shares or in compliance with Rule 145 promulgated
under the Securities Act or another applicable exemption from the registration
requirements of the Securities Act. Generally, Rule 145 permits BancGroup Common
Stock held by such shareholders to be sold in accordance with certain provisions
of Rule 144 under the Securities Act. In general, these provisions of Rule 144
permit a person to sell on the open market in brokers transactions within any
three month-period a number of shares that does not exceed the greater of 1% of
the then outstanding shares of BancGroup Common Stock or the average weekly
trading volume in BancGroup Common Stock reported on NYSE during the four
calendar weeks preceding such sale. Sales under Rule 144 are also subject to the
availability of current public information about BancGroup which BancGroup has
agreed to make available. The restrictions on sales will cease to apply under
most circumstances once the former Bankshares affiliate has held the BancGroup
Common Stock for at least two years. BancGroup Common Stock held by affiliates
of Bankshares who become affiliates of BancGroup will be subject to additional
restrictions on the ability of such persons to resell such shares.
 
     Bankshares will provide BancGroup with such information as may be
reasonably necessary to determine the identity of those persons (primarily
officers, directors and principal shareholders) who may be deemed to be
affiliates of Bankshares. Bankshares will also obtain from each such person a
written undertaking to the effect that no sale or transfer will be made of any
shares of BancGroup Common Stock by such person except pursuant to Rule 145 or
pursuant to an effective registration statement or an exemption from
registration under the Securities Act. Receipt of such an undertaking is a
condition to BancGroup's obligation to close the Merger. If such undertakings
are not received and BancGroup waives receipt of such condition, the
certificates for the shares of BancGroup Common Stock to be issued to such
person will contain an appropriate restrictive legend and appropriate stock
transfer orders will be given to BancGroup's stock transfer agent.
 
     The undertaking from each Bankshares affiliate will also provide that,
notwithstanding the permissible sale of stock described above, each affiliate of
Bankshares may not sell or in any other way reduce his or her risk relative to
any shares of Bankshares Common Stock or of BancGroup Common Stock during the
period commencing thirty days prior to the Effective Date and ending on the date
on which financial results covering at least thirty days of post-Merger combined
operations of BancGroup and Bankshares have been published.
 
ACCOUNTING TREATMENT
 
     BancGroup will account for the Merger as a pooling-of-interests transaction
in accordance with generally accepted accounting principles, which, among other
things, requires that the number of shares of Bankshares Common Stock acquired
for cash pursuant to the exercise of dissenters' rights or in lieu of fractional
shares not exceed 10% of the outstanding shares of Bankshares Common Stock.
Under this accounting treatment, assets and liabilities of Bankshares would be
added to those of BancGroup at their recorded book values, and
 
                                       25
<PAGE>   37
 
the shareholders' equity of the two companies would be combined in BancGroup's
consolidated balance sheet. Financial statements of BancGroup issued after the
Effective Date of the Merger will be restated to reflect the consolidated
operations of BancGroup and Bankshares as if the Merger had taken place prior to
the periods covered by the financial statements.
 
NYSE REPORTING OF BANCGROUP COMMON STOCK ISSUED IN THE MERGER
 
     Sales of BancGroup Common Stock to be issued in the Merger in exchange for
Bankshares Common Stock will be reported on the NYSE.
 
TREATMENT OF BANKSHARES OPTIONS
 
     Assumption of Options.  As of the date of this Prospectus, Bankshares had
granted Bankshares Options to its directors and certain executive officers which
entitled the holders thereof to acquire up to 46,750 shares of Bankshares Common
Stock. On the Effective Date, BancGroup shall assume all Bankshares Options
outstanding, and each such option shall represent the right to acquire BancGroup
Common Stock on substantially the same terms as are applicable to the Bankshares
Options except as specified below. The registration statement registering the
shares of BancGroup Common Stock issued pursuant to the Merger also registers
the shares of BancGroup Common Stock to be issued pursuant to the exercise of
Bankshares Options assumed by BancGroup. The number of shares of BancGroup
Common Stock to be issued pursuant to such options shall equal the number of
shares of Bankshares Common Stock subject to such Bankshares Options multiplied
by the Exchange Ratio, provided that no fractional shares of BancGroup Common
Stock shall be issued and the number of shares of BancGroup Common Stock to be
issued upon the exercise of Bankshares Options, if a fractional share exists,
shall equal the number of whole shares obtained by rounding to the nearest whole
number, taking into account such fraction. The exercise price for the
acquisition of BancGroup Common Stock shall be the exercise price for each share
of Bankshares Common Stock subject to such options divided by the Exchange
Ratio, adjusted appropriately for any rounding to whole shares that may be done.
For these purposes, the "Exchange Ratio" shall mean the result obtained by
dividing $27.39 by the Market Value.
 
     The Bankshares Options were issued pursuant to a plan adopted by the Board
of Directors of Bankshares (the "Option Plan"). The Option Plan is not qualified
under Section 401(a) of the Internal Revenue Code of 1986, as amended, nor is it
subject to the Employee Retirement Income Security Act of 1974. Bankshares
Options are not transferrable except under the laws of descent and distribution.
 
     Purpose of the Option Plan.  The purpose of the Option Plan is to assist
the Bank in retaining the employment of valued employees by offering them a
greater stake in the Bank's success and a closer identity with it, and to aid in
obtaining the services of individuals whose employment would be helpful to the
Bank and would contribute to its success. BancGroup believes that its assumption
of the Bankshares Options will be consistent with this purpose. No further
options will be granted under the Option Plan after the Merger.
 
     Tax Consequences -- Incentive Options.  BancGroup believes, after
consultation with legal counsel, that if the options issued under the Option
Plan as incentive options qualified as such at the time of grant, the option
after assumption by BancGroup will continue to qualify as "incentive stock
options," under Section 422 of the Internal Revenue Code of 1986, as amended.
Under the Internal Revenue Code no income will result to a grantee of any such
option upon the granting or exercising of an option by the grantee, and
BancGroup will not be entitled to a tax deduction by reason of such grant or
exercise.
 
     If, after exercising the option, the employee holds the stock obtained
through exercise for at least two years after the date of option grant and at
least one year after the stock was obtained, the employee's gain (if any) on
selling the stock will generally be treated as a long term capital gain.
Generally, the employee's alternative minimum taxable income for minimum tax
purposes will be increased by the difference between the option price and the
fair market value of the stock on the date of exercise.
 
     If the holding period requirements just stated are not met, then any gain
on the sale of the stock will be taxed partly or entirely at ordinary income tax
rates. If the stock is held for less than the required holding
 
                                       26
<PAGE>   38
 
period, then the difference between the option exercise price and the fair
market value of the stock on the date of exercise will be taxed at ordinary
income tax rates. The gain equal to the increase in the fair market value of the
stock after the date of exercise of the option will generally be taxed as
capital gain.
 
     It should be understood that the holding periods discussed above relate
only to federal income tax treatment and not to securities law restrictions on
the sale of shares obtained through an option.
 
     The foregoing statements concerning federal income tax treatment are
necessarily general and may not apply in a particular instance. No legal opinion
has been received by BancGroup or Bankshares respecting the effect of the Merger
on holders of Bankshares Options or of the exercise of such options. Option
holders should contact their own professional tax advisors for advice concerning
their particular tax situation and any changes in the tax law since the date of
this Prospectus.
 
     Administration.  The shares of stock to be delivered upon the exercise of
Bankshares Options under the Option Plan shall be made available after the
Merger, from the authorized but unissued shares of BancGroup's Common Stock.
 
     The Option Plan is to be administered, after the Merger, by the Personnel
and Compensation Committee (the "Committee") of the board of directors of
BancGroup. All members of the Committee are directors of BancGroup. The Chairman
of the Committee, John C. H. Miller, Jr., receives employee-related compensation
from BancGroup and holds options under BancGroup's stock option plans. Mr.
Miller is a member of a law firm that performs legal services for BancGroup. See
"LEGAL OPINIONS." Another member of the Committee, Jack H. Rainer, is Chairman
of Bankers Credit Life Insurance Company, which provides credit life insurance
on certain loans made by Colonial Bank, BancGroup's Alabama bank subsidiary. The
members of the Committee serve at the pleasure of the board of directors of
BancGroup. The Committee shall interpret the Option Plan and resolve questions
presented by holders of options under the Option Plan. Requests for information
or questions about the Option Plan should be directed to BancGroup's Corporate
Secretary, at the offices of BancGroup, Post Office Box 1108, One Commerce
Street, Montgomery, Alabama 36102, telephone: (334) 240-5000.
 
     Exercise of Options.  After a Bankshares Option becomes exercisable in
accordance with its terms, it may be exercised by the holder by giving written
notice to BancGroup on a form provided by BancGroup and, by paying to BancGroup
in cash the exercise price of the shares to be acquired under a Bankshares
Option. Payment may be made to BancGroup by cash, check, bank draft, or money
order, or, if the Committee agrees in a particular instance, by delivering
BancGroup stock already owned by the option holder. All Bankshares Options must
be exercised within 90 days after the Effective Date or such options will be
forfeited.
 
     Amendment and Other Matters.  BancGroup's board of directors may at any
time amend the Option Plan, except that no amendment may make any change in any
option already granted which would adversely affect the rights of any
participant.
 
     It is not anticipated that BancGroup will make any reports to option
holders regarding the amount or status of Bankshares Options held. Option
holders may obtain such information from BancGroup at the address given above.
 
     The shares subject to options will be obtained by BancGroup from authorized
but unissued shares. BancGroup has reserved sufficient authorized but unissued
shares for issuance pursuant to options under the Option Plan and does not
anticipate acquiring any shares in the open market for such purposes.
 
TREATMENT OF SERIES A DEBENTURES
 
     As of the date of this Prospectus, Bankshares had outstanding Series A
Debentures which are convertible into 64,773 shares of Bankshares Common Stock.
On the Effective Date, BancGroup shall assume all outstanding Series A
Debentures and such Debentures shall be convertible into shares of BancGroup
Common Stock, with each share of Bankshares Common Stock that would have been
issued upon conversion of such Debenture being convertible into such number of
shares of BancGroup Common Stock equal to one share of Bankshares Common Stock
multiplied by the Exchange Ratio. No fractional shares of BancGroup
 
                                       27
<PAGE>   39
 
Common Stock shall be issued upon conversion of the Series A Debentures,
however, and any fractions to be issued shall be paid in cash to the holder of
the Debenture.
 
                    COMPARATIVE MARKET PRICES AND DIVIDENDS
 
BANCGROUP
 
     BancGroup Common Stock is listed for trading on the NYSE. The Common Stock
was first listed on the NYSE on February 24, 1995. Prior to February 21, 1995,
BancGroup had two classes of common stock outstanding, Class A and Class B. The
Class B was not publicly traded. The Class A Common Stock was traded in the
over-the-counter market and quoted on the NASDAQ National Market System. The
BancGroup Class A Common Stock had more limited voting rights than the BancGroup
Class B Common Stock. The Class A and Class B Common Stock were reclassified
into one class of Common Stock on February 21, 1995, and the Class A Common
Stock ceased to be quoted on NASDAQ on February 24, 1995.
 
     The following table shows the dividends paid per share and indicates the
high and low closing prices for the BancGroup Class A Common Stock as reported
by the NASDAQ National Market System up to February 24, 1995, and the same
information reported by the NYSE for the BancGroup Common Stock commencing
February 24, 1995.

     On August 2, 1996, 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 $33 1/4 per share.
 
     At June 30, 1996, BancGroup's subsidiaries accounted for approximately 98%
of BancGroup's consolidated assets. BancGroup derives substantially all of its
income from dividends received from its subsidiaries. Various statutory
provisions and regulatory policies limit the amount of dividends the subsidiary
banks may pay without regulatory approval. In addition, federal statutes
restrict the ability of subsidiary banks to make loans to BancGroup, and
regulatory policies may also restrict such dividends.

     Because Bankshares and the Bank are relatively new operations, the
directors of Bankshares and the Bank have opted to retain earnings in order to
insure the success of the entities' operations and have not initiated the
payment of cash dividends.
 
     Immediately prior to the public announcement of the Merger on August 2,
1996, Bankshares Common Stock was trading at $20.00. On [February 24], 1996, the
last sales price per share reported for Bankshares Common Stock was $[20.00].
 
     The Agreement restricts Bankshares' ability to pay dividends prior to the
Effective Date. See "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
BancGroup Common Stock, par value $2.50 per share, and 1,000,000 shares of its
Preference Stock, par value $2.50 per share. As of September 19, 1996, there
were issued and outstanding a total of 16,296,558 shares of BancGroup Common
Stock. No shares of Preference Stock are issued and outstanding. BancGroup
issued in 1986 $28,750,000 in principal amount of its 7 1/2% Convertible
Subordinated Debentures due 2011 (the "1986 Debentures") of which $8,082,000 are
currently outstanding and are convertible at any time into 277,177 shares of
BancGroup Common Stock, subject to adjustment. There are 767,571 shares of
BancGroup Common Stock subject to issue upon exercise of options under
BancGroup's stock option plans. In addition to BancGroup Common Stock to be
issued in the Merger, BancGroup will issue additional shares of its Common Stock
in pending acquisitions. See "BUSINESS OF BANCGROUP -- Proposed Affiliate
Banks."
 
     The following statements with respect to BancGroup Common Stock and
Preference Stock are brief summaries of material provisions of Delaware law, the
Restated Certificate of Incorporation (the "Certificate"), as amended, and
bylaws of BancGroup, do not purport to be complete and are qualified in their
entirety by reference to the foregoing.
 
BANCGROUP COMMON STOCK
 
     Dividends.  Subject to the rights of holders of BancGroup's Preference
Stock, if any, to receive certain dividends prior to the declaration of
dividends on shares of BancGroup Common Stock, when and as dividends, payable in
cash, stock or other property, are declared by the BancGroup Board of Directors,
the holders of BancGroup Common Stock are entitled to share ratably in such
dividends.
 
     Voting Rights.  Each holder of BancGroup Common Stock has one vote for each
share held on matters presented for consideration by the stockholders.
 
     Preemptive Rights.  The holders of BancGroup Common Stock have no
preemptive rights to acquire any additional shares of BancGroup.
 
     Issuance of Stock.  The BancGroup Certificate authorizes the BancGroup
Board to issue authorized shares of BancGroup Common Stock without stockholder
approval. However, BancGroup's Common Stock is listed on the NYSE, which
requires stockholder approval of the issuance of additional shares of BancGroup
Common Stock under certain circumstances.
 
     Liquidation Rights.  In the event of liquidation, dissolution or winding-up
of BancGroup, whether voluntary or involuntary, the holders of BancGroup Common
Stock will be entitled to share ratably in any of
 
                                       29
<PAGE>   41
 
its assets or funds that are available for distribution to its stockholders
after the satisfaction of its liabilities (or after adequate provision is made
therefor) and after preferences of any outstanding Preference Stock.
 
PREFERENCE STOCK
 
     BancGroup's Preference Stock may be issued from time to time as a class
without series, or if so determined by the BancGroup Board of Directors, either
in whole or in part in one or more series. The voting rights, and such
designations, preferences and relative, participating, optional or other special
rights, if any, and the qualifications, limitations or restrictions thereof, if
any, including, but not limited to, the dividend rights, conversion rights,
redemption rights and liquidation preferences, if any, of any wholly unissued
series of BancGroup Preference Stock (or of the entire class of BancGroup
Preference Stock if none of such shares has been issued), the number of shares
constituting any such series and the terms and conditions of the issue thereof
may be fixed by resolution of the BancGroup Board of Directors. BancGroup
Preference Stock may have a preference over the BancGroup Common Stock with
respect to the payment of dividends and the distribution of assets in the event
of the liquidation or winding-up of BancGroup and such other preferences as may
be fixed by the BancGroup Board.
 
1986 DEBENTURES
 
     BancGroup issued in 1986 its 7 1/2% Convertible Subordinated Debentures due
2011 (the "1986 Debentures") in the total principal amount of $28,750,000. The
1986 Debentures were issued under a trust indenture (the "1986 Indenture")
between BancGroup and SunTrust Bank, Atlanta, Georgia, as trustee.
 
     The 1986 Debentures will mature on March 31, 2011, and are convertible at
any time into shares of BancGroup Common Stock at the option of a holder
thereof, at the conversion price of $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 277,177 shares of such BancGroup Common Stock will be
issued. The 1986 Debentures are redeemable, in whole or in part, at the option
of BancGroup at certain premiums until 1996, when the redemption price shall be
equal to 100% of the face amount of the 1986 Debentures plus accrued interest.
The payment of principal and interest on the 1986 Debentures is subordinate, to
the extent provided in the 1986 Indenture, to the prior payment when due of all
Senior Indebtedness of BancGroup. "Senior Indebtedness" is defined as any
indebtedness of BancGroup for money borrowed, or any indebtedness incurred in
connection with an acquisition or with a merger or consolidation, outstanding on
the date of execution of the 1986 Indenture as originally executed, or
thereafter created, incurred or assumed, and any renewal, extension,
modification or refunding thereof, for the payment of which BancGroup (which
term does not include BancGroup's consolidated or unconsolidated subsidiaries)
is at the time of determination responsible or liable as obligor, guarantor or
otherwise. Senior Indebtedness does not include (i) indebtedness as to which, in
the instrument creating or evidencing the same or pursuant to which the same is
outstanding, it is provided that such indebtedness is subordinate in right of
payment to any other indebtedness of BancGroup, and (ii) indebtedness which by
its terms states that such indebtedness is subordinate to or equally subordinate
with the 1986 Debentures.
 
     At June 30, 1996, BancGroup's Senior Indebtedness as defined in the 1986
Indenture aggregated approximately $716 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 power of BancGroup's Board to
issue additional shares of BancGroup Common Stock may help delay or deter a
change in control by increasing the number of shares needed to gain control. See
"BancGroup Common Stock." The following provisions also may deter any change in
control of BancGroup.
 
     Classified Board.  BancGroup's Board of Directors is classified into three
classes, as nearly equal in number as possible, with the members of each class
elected to three-year terms. Thus, one-third of BancGroup's Board of Directors
is elected by stockholders each year. With this provision, two annual elections
are required in order to change a majority of the Board of Directors. There are
currently 19 directors of BancGroup. This provision of BancGroup's Certificate
also stipulates that (i) directors can be removed only for cause upon a vote of
80% of the voting power of the outstanding shares entitled to vote in the
election of directors, voting as a class, (ii) vacancies in the Board may only
be filled by a majority vote of the directors remaining in office, (iii) the
maximum number of directors shall be fixed by resolution of the Board of
Directors, and (iv) the provisions relating to the classified Board can only be
amended by the affirmative vote of the holders of at least 80% of the voting
power of the outstanding shares entitled to vote in the election of directors,
voting as a class.
 
     Business Combinations.  Certain "Business Combinations" of BancGroup with a
"Related Person" may only be undertaken with the affirmative vote of at least
75% of the outstanding shares of "Voting Stock," plus the affirmative vote of at
least 67% of the outstanding shares of Voting Stock, not counting shares owned
by the Related Person, unless the Continuing Directors of BancGroup approve such
Business Combination. A "Related Person" is a person, or group, who owns or
acquires 10% or more of the outstanding shares of BancGroup Common Stock,
provided that no person shall be a Related Person if such person would have been
a Related Person on the date of approval of this provision by BancGroup's Board
of Directors, i.e., April 20, 1994. An effect of this provision may be to
exclude Robert E. Lowder, the current Chairman and President of BancGroup, and
certain members of his family from the definition of Related Person. A
"Continuing Director" is a director who was a member of the Board of Directors
immediately prior to the time a person became a Related Person. This provision
may not be amended without the affirmative vote of the holders of at least 75%
of the outstanding shares of Voting Stock, plus the affirmative vote of the
outstanding shares of at least 67% of the outstanding Voting Stock, excluding
shares held by a Related Person. This provision may have the effect of giving
the incumbent Board of Directors a veto over a merger or other Business
Combination that could be desired by a majority of BancGroup's stockholders. The
current Board of Directors of BancGroup owns approximately 13% of the
outstanding shares of BancGroup Common Stock.
 
     Board Evaluation of Mergers.  BancGroup's Certificate permits the Board of
Directors to consider certain factors such as the character and financial
stability of the other party, the projected social, legal, and economic effects
of a proposed transaction upon the employees, suppliers, regulatory agencies and
customers and communities of BancGroup, and other factors when considering
whether BancGroup should undertake a merger, sale of assets, or other similar
transaction with another party. This provision may not be amended except by the
affirmative vote of at least 80% of the outstanding shares of BancGroup Common
Stock. This provision may give greater latitude to the Board of Directors in
terms of the factors which the board may consider in recommending or rejecting a
merger or other Business Combination of BancGroup.
 
     Director Authority.  BancGroup's Certificate prohibits stockholders from
calling special stockholders' meetings and acting by written consent. It also
provides that only BancGroup's Board of Directors has the authority to undertake
certain actions with respect to governing BancGroup such as appointing
committees, electing officers, and establishing compensation of officers, and it
allows the Board to act by majority vote.
 
     Bylaw Provisions.  BancGroup's bylaws provide that stockholders wishing to
propose nominees for the Board of Directors or other business to be taken up at
an annual meeting of BancGroup stockholders must
 
                                       31
<PAGE>   43
 
comply with certain advance written notice provisions. These bylaw provisions
are intended to provide for the more orderly conduct of stockholder meetings but
could make it more difficult for stockholders to nominate directors or introduce
business at stockholder meetings.
 
     Delaware Business Combination Statute.  Subject to some exceptions,
Delaware law prohibits BancGroup from entering into certain "business
combinations" (as defined) involving persons beneficially owning 15% or more of
the outstanding BancGroup Common Stock (or who is an affiliate of BancGroup and
has over the past three years beneficially owned 15% or more of such stock)
(either, for the purpose of this paragraph, an "Interested Stockholder"), unless
the BancGroup Board has approved either (i) the business combination or (ii)
prior to the stock acquisition by which such person's beneficial ownership
interest reached 15% (a "Stock Acquisition"), the Stock Acquisition. The
prohibition lasts for three years from the date of the Stock Acquisition.
Notwithstanding the preceding, Delaware law allows BancGroup to enter into a
business combination with an Interested Stockholder if (i) the business
combination is approved by the BancGroup Board of Directors and authorized by an
affirmative vote of at least 66 2/3% of the outstanding voting stock of
BancGroup which is not owned by the Interested Stockholder or (ii) upon
consummation of the transaction which resulted in the stockholder becoming an
Interested Stockholder, such stockholder owned at least 85% of the outstanding
stock of BancGroup (excluding BancGroup stock held by officers and directors of
BancGroup or by certain BancGroup stock plans). These provisions of Delaware law
apply simultaneously with the provisions of BancGroup's Certificate relating to
business combinations with a related person, described above at "Business
Combinations," but they are generally less restrictive than BancGroup's
Certificate.
 
     Control Acquisitions.  As it relates to BancGroup, the Change in Bank
Control Act of 1978 prohibits a person or group of persons from acquiring
"control" of a bank holding company unless the Federal Reserve has been given 60
days' prior written notice of such proposed acquisition and within that time
period the Federal Reserve has not issued a notice disapproving the proposed
acquisition or extending for up to another 30 days the period during which such
a disapproval may be issued. An acquisition may be made prior to the expiration
of the disapproval period if the Federal Reserve issues written notice of its
intent not to disapprove the action. Under a rebuttable presumption established
by the Federal Reserve, the acquisition of more than 10% of a class of voting
stock of a bank holding company with a class of securities registered under
Section 12 of the Exchange Act, such as BancGroup, would, under the
circumstances set forth in the presumption, constitute the acquisition of
control. The receipt of revocable proxies, provided the proxies terminate within
a reasonable time after the meeting to which they relate, is not included in
determining percentages for change in control purposes.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
     If the Merger is consummated, all shareholders of Bankshares will become
holders of BancGroup Common Stock. The rights of the holders of the Bankshares
Common Stock who become holders of the BancGroup Common Stock following the
Merger will be governed by BancGroup's Certificate and bylaws, as well as the
laws of Delaware, the state in which BancGroup is incorporated.
 
     The following summary compares the rights of the shareholders of Bankshares
Common Stock with the rights of the holders of the BancGroup Common Stock. For a
more complete description of the rights of the holders of BancGroup Common
Stock, see "BANCGROUP CAPITAL STOCK AND DEBENTURES."
 
     The following information is qualified in its entirety by BancGroup's
Certificate and bylaws, and Bankshares' Articles of Incorporation and bylaws,
the Delaware General Corporation Law (the "Delaware GCL") and the Georgia
Business Corporation Code ("GBCC").

     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."
 
     Bankshares.  Like BancGroup, Bankshares' Articles of Incorporation provide
for a classified Board of Directors with three classes and provide that voting
stock does not have cumulative voting rights.
 
REMOVAL OF DIRECTORS
 
     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.
 
     Bankshares.  Bankshares' Articles of Incorporation provide that directors
of Bankshares may be removed during their terms for cause only by the
affirmative vote of the holders of a majority of the outstanding shares of
Bankshares Common Stock; or without cause only by the affirmative vote of
holders of at least two-thirds of the outstanding shares.
 
VOTING
 
     BancGroup.  Each stockholder of BancGroup is entitled to one vote for each
share of BancGroup Common Stock held, and such holders are not entitled to
cumulative voting rights in the election of directors.
 
     Bankshares.  Like BancGroup, each stockholder of Bankshares is entitled to
one vote for each share of Bankshares Common Stock held and such holders are not
entitled to cumulative voting rights in the election of directors.
 
PREEMPTIVE RIGHTS
 
     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.
 
     Bankshares.  Like BancGroup, the holders of Bankshares Common Stock have no
preemptive rights to acquire any additional shares of Bankshares Common Stock.
 
DIRECTORS' LIABILITY
 
     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
 
                                       33
<PAGE>   45
 
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.
 
     Bankshares.  Bankshares' Articles of Incorporation eliminate the potential
personal liability of a director for monetary damages to Bankshares or its
shareholders for breach of duty as a director with certain exceptions. There is
no elimination of liability for (a) a breach of duty involving appropriation of
a business opportunity of Bankshares, (b) an act or omission not in good faith
or involving intentional misconduct or knowing violation of law, (c) a
transaction from which the director derives an improper material tangible
personal benefit, or (d) as to the types of liability set forth in Section
14-2-832 of the Georgia Business Corporation Code dealing with unlawful
distribution of corporate assets to shareholders. This limitation does not
eliminate the right of Bankshares or its shareholders to seek injunctive or
other equitable relief not involving monetary damages.
 
INDEMNIFICATION
 
     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), he or she must be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.
 
     BancGroup maintains an officers' and directors' insurance policy and a
separate indemnification agreement pursuant to which officers and directors of
BancGroup would be entitled to indemnification against certain liabilities,
including reimbursement of certain expenses that extends beyond the minimum
indemnification provided by Section 145 of the Delaware GCL.
 
     Bankshares.  Bankshares' bylaws contain certain provisions which provide
indemnification to directors and officers of Bankshares that is broader than the
protection expressly mandated in Sections 14-2-850 et seq.
of the Georgia Business Corporation Code. These sections expressly allow
Bankshares to provide these broader indemnification rights to its directors and
officers, subject to shareholder approval.
 
     The indemnification provisions of its bylaws require Bankshares to
indemnify persons who are parties to any civil, criminal, administrative or
investigative action, suit or proceeding by reason of the fact that such person
was or is a director, officer, employee or agent of Bankshares. Except as noted
below, these persons would be indemnified against expenses and against any
judgments, fines, and amounts paid in settlement actually and reasonably
incurred by them. These persons may also be entitled to have Bankshares advance
any such expenses (including, but not limited to, attorneys' fees and court
costs) prior to the final disposition of the proceeding upon an undertaking to
repay Bankshares if it is ultimately determined that they are not entitled to
indemnification. Under its bylaws, Bankshares shall indemnify a director,
officer, employee or agent if the individual acted in a manner he or she
believed in good faith to be in or not opposed to the best interests
 
                                       34
<PAGE>   46
 
of Bankshares and, in the case of a criminal proceeding, if the individual had
no reasonable cause to believe his or her conduct was unlawful.
 
SPECIAL MEETINGS OF STOCKHOLDERS; ACTION WITHOUT A MEETING
 
     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.
 
     Bankshares.  A special meeting of shareholders may be called by Bankshares'
Board of Directors, its President or by the written request of any one or more
shareholders owning an aggregate of not less than 25% of Bankshares Common
Stock. Any action which may be taken at a meeting of shareholders may also be
taken without a meeting if a consent in writing, setting forth the action, is
signed by those persons who would be entitled to vote at a meeting having voting
power to cast not less than the minimum number of votes that would be necessary
to authorize such action at a meeting at which all shares entitled to vote were
present and voted.
 
MERGERS, SHARE EXCHANGES AND SALES OF ASSETS
 
     BancGroup.  The Delaware GCL provides that mergers and sales of
substantially all of the assets of Delaware corporations must be approved by a
majority of the outstanding stock of the corporation entitled to vote thereon.
The Delaware GCL 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.
 
     Bankshares.  Bankshares' Articles of Incorporation provide that, with
certain exceptions, any merger or consolidation involving Bankshares or any sale
or other disposition of all or substantially all of its assets will require the
affirmative vote of the holders of at least two-thirds of the outstanding shares
of Bankshares Common Stock. However, exceptions to this rule exist where (a)
two-thirds of the Board has approved a merger or similar transaction prior to
its consummation or (b) Bankshares is engaged in a merger or similar transaction
with a subsidiary. In cases where one of these exceptions applies, the
applicable provisions of the Georgia Business Corporation Code govern and
shareholder approval of the transaction would require a favorable vote by a
majority of all the votes entitled to be cast.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION AND BYLAWS
 
     BancGroup.  Under the Delaware GCL, a Delaware corporation's certificate of
incorporation may be amended by the affirmative vote of the holders of a
majority of the outstanding shares entitled to vote thereon, and a majority of
the outstanding stock of each class entitled to vote as a class, unless the
certificate requires the vote of a larger portion of the stock. The BancGroup
Certificate requires "supermajority" stockholder approval to amend or repeal any
provision of, or adopt any provision inconsistent with, certain provisions in
the BancGroup Certificate governing (i) the election or removal of directors,
(ii) business combinations between BancGroup and a Related Person, and (iii)
board of directors evaluation of business combination procedures. See "BANCGROUP
CAPITAL STOCK AND DEBENTURES -- Changes in Control."
 
                                       35
<PAGE>   47
 
     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.
 
     Bankshares.  The Georgia Business Corporation Code generally provides that
a Georgia corporation's articles of incorporation may be amended by the
affirmative vote of a majority of the shares entitled to vote thereon unless the
articles of incorporation provide for a higher or lower voting requirement.
Bankshares' Articles of Incorporation provide that any amendment to the articles
dealing with classifying the Board of Directors, changing the number of
directors, removing directors, limiting liability of directors and officers,
supermajority voting on certain transactions, and evaluating acquisition
proposals require the affirmative vote of holders of at least two-thirds of the
outstanding shares of Bankshares Common Stock unless two-thirds of the Board
approves the amendment, in which case the applicable provisions of the Georgia
Business Corporation Code would govern and the amendment would be approved by
the affirmative vote of a majority of the shares entitled to vote thereon.
 
     Pursuant to the Georgia Business Corporation Code and Bankshares' bylaws,
its bylaws of a Georgia corporation may be amended by the Board of Directors or
by the shareholders.
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
     BancGroup.  Under the Delaware GCL, a stockholder has the right, in certain
circumstances, to dissent from certain corporate transactions and receive the
fair value of his or her shares in cash in lieu of the consideration he or she
otherwise would have received in the transaction. For this purpose, "fair value"
may be determined by all generally accepted techniques of valuation used in the
financial community, excluding any element of value arising from the
accomplishment or expectation of the transaction, but including elements of
future value that are known or susceptible of proof. Such fair value is
determined by the Delaware Court of Chancery if a petition for appraisal is
timely filed. Appraisal rights are not available, however, to stockholders of a
corporation (i) if the shares are listed on a national securities exchange (as
is BancGroup Common Stock) or quoted on the NASDAQ National Market System, or
held of record by more than 2,000 stockholders (as is BancGroup Common Stock),
and (ii) stockholders are permitted by the terms of the merger or consolidation
to accept in exchange for their shares (a) shares of stock of the surviving or
resulting corporation, (b) shares of stock of another corporation listed on a
national securities exchange or held of record by more than 2,000 stockholders,
(c) cash in lieu of fractional shares of such stock, or (d) any combination
thereof. Stockholders are not permitted appraisal rights in a merger if such
corporation is the surviving corporation and no vote of its stockholders is
required.
 
     Bankshares.  The rights of appraisal of dissenting shareholders under
Georgia law are described above under "The Merger -- Rights of Dissenting
Shareholders."
 
ANTITAKEOVER STATUTES
 
     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."
 
     Bankshares.  Bankshares is not subject to the business combination statute
nor to the fair price statute set forth in the Georgia Business Corporation Code
at Section 14-2-1131 through Section 14-2-1133 and Section 14-2-1110 through
Section 14-2-1113, respectively.
 
PREFERRED STOCK
 
     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."
 
     Bankshares.  Bankshares' Articles of Incorporation do not authorize the
issuance of preferred stock.

EFFECT OF THE MERGER ON BANKSHARES SHAREHOLDERS
 
     As of      , 1996, Bankshares had [471] shareholders of record and
[700,836] outstanding shares of Bankshares Common Stock. As of that date,
BancGroup had 16,296,558 shares of BancGroup Common Stock outstanding with 5,914
stockholders of record.
 
     Assuming no exercises of Bankshares Options at the Effective Date and a
Market Value of BancGroup Common Stock of $35.05, calculated as of September 19,
1996, an aggregate amount of 547,672 shares of BancGroup Common Stock would be
issued to the shareholders of Bankshares pursuant to the Merger. These shares
would represent approximately 3.2% of the total shares of BancGroup Common Stock
outstanding after the Merger, not counting any shares of BancGroup Common Stock
to be issued in other pending acquisitions.
 
     The issuance of the BancGroup Common Stock pursuant to the Merger will
reduce the percentage interest of the BancGroup Common Stock currently held by
each principal stockholder and each director and officer of BancGroup. As a
group, the directors and officers of BancGroup who own 12.82% of BancGroup's
outstanding shares would own 12.42% after the Merger. See "BUSINESS OF
BANCGROUP -- Voting Securities and Principal Stockholders."

              CONDENSED PRO FORMA STATEMENTS OF INCOME (UNAUDITED)
 
     The following summaries include (i) the condensed consolidated statements
of income of BancGroup and subsidiaries on a historical basis for the six months
ended June 30, 1996 and 1995 (as restated), and the years ended December 31,
1995, 1994 and 1993 (as restated), (ii) the condensed consolidated statements of
income of Bankshares for the six months ended June 30, 1996 and 1995 and the
years ended December 31, 1995, 1994 and 1993, (iii) the condensed consolidated
statements of income of Jefferson, a probable combination with BancGroup, for
the six months ended June 30, 1996 (as amended) and 1995 and the years ended
December 31, 1995, 1994, and 1993, (iv) the combined presentation of condensed
consolidated statements of income of the other probable combinations for the six
months ended June 30, 1996 and 1995 and the years ended December 31, 1995, 1994
and 1993, (v) adjustments to give effect to the pooling of interests method
combination with Bankshares and the proposed purchase method combination with
First Family and the proposed pooling of interests method combinations with
Jefferson, and the other probable combinations, and (vi) the pro forma combined
condensed consolidated statements of income of BancGroup and subsidiaries as if
such combinations had occurred on January 1, 1993. Note that for purchase method
combinations, Article 11 of Regulation S-X requires pro forma statements of
income to be presented for only the most recent fiscal year and interim period.
Accordingly, only the condensed consolidated statements of income for the six
months ended June 30, 1996 and the year ended December 31, 1995 are included in
(iv) above for First Family.
 
     These pro forma statements should be read in conjunction with the
accompanying notes and the separate consolidated statements of income of
BancGroup and subsidiaries (as restated) and Bankshares, incorporated by
reference herein. These pro forma statements exclude the effect of two
nonrecurring charges related to Jefferson in the amount of $4.4 million net of
tax. These pro forma statements exclude the effects of one immaterial purchase
method combination which was completed by BancGroup on July 8, 1996. The pro
forma information may not necessarily be indicative of future results.

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, 1995, 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 BHCA and many
of the Federal Reserve's regulations promulgated thereunder. It is also subject
to regulation by the OTS, as a savings and loan holding company, and by the
Georgia Department of Banking and Finance. With the exception of OTS, Bankshares
is subject to the same supervision and regulation.
 
     BancGroup's subsidiary banks (the "Subsidiary Banks") as well as the Bank
are subject to supervision and examination by applicable federal and state
banking agencies. 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 BHCA 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
 
                                       57
<PAGE>   69
 
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 BHCA to permit bank holding companies, 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.
 
     On September 30, 1996, Congress passed and the President signed a
continuing resolution which directed the FDIC to set a one-time special
assessment on SAIF-insured deposits in an amount sufficient to capitalize the
Savings Association Insurance Fund ("SAIF") at the reserve level previously
mandated by statute. The FDIC Board met on October 8, 1996, and set this special
assessment at $0.657 per $100 of SAIF-insured deposits. Though the special
assessment applies to SAIF-insured deposits, the special assessment, under the
legislation enacted into law on September 30, 1996, will not be applied to 20%
of those SAIF-insured deposits held by certain so-called Oakar and Sasser
institutions. Thus, the special assessment's effective rate with respect to the
SAIF-insured deposits in such institutions will be $0.525 per $100 of their
SAIF-insured deposits. In addition, the legislation enacted by Congress provides
that the annual $800-million FICO bond service will be shared by both
BIF-insured institutions and SAIF-insured institutions. Prior to this
legislation, this bond service was the obligation of SAIF members only. This
sharing of the FICO bond service obligation, coupled with the capitalization of
SAIF to the mandatory reserve level, will cause the regular SAIF deposit
insurance premium rate to fall from $0.23 per $100 of SAIF-insured deposits to
under $0.07, assuming the SAIF does not incur any large losses which would
necessitate recapitalization of the Fund. The regular BIF deposit insurance
premium rate will be under $0.02 per $100 of BIF-insured deposits. The
differential between BIF and SAIF caused by the FICO bond service will terminate
on December 31, 1999, after which time the FICO bond service will be divided on
a strictly pro rata basis and SAIF and BIF rates will be equal unless one of the
deposit insurance funds requires recapitalization. BIF and SAIF premium rates
will be approximately $0.024 per $100 of deposits after December 31, 1999. In
the event of a merger of the thrift and bank charters, the differential could be
eliminated prior to December 31, 1999. The legislation also provides for a
merger of SAIF and BIF if charter merger occurs. Such a merger of the funds,
assuming a merger of the charters has taken place, would occur on January 1,
1999. BancGroup's subsidiary banks hold deposits which are insured by both SAIF
and BIF. The SAIF-insured deposits in all of BancGroup's subsidiary institutions
total approximately $850 million, before adjusting for certain allowances such
as the 20 percent discount referenced above, which would be subject to the
special assessment.
 
     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.

                         ADJOURNMENT OF SPECIAL MEETING
 
     Approval of the Merger by Bankshares' shareholders requires the affirmative
vote of at least a majority of the total votes eligible to be cast at the
Special Meeting. In the event there are an insufficient number of shares of
Bankshares Common Stock present in person or by proxy at the Special Meeting to
approve the Merger, Bankshares' Board of Directors in its discretion may adjourn
the Special Meeting to a later date provided a majority of the shares present at
the Special Meeting have voted in favor of adjournment. The place and date to
which the Special Meeting would be adjourned would be announced at the Special
Meeting. If it is necessary to adjourn the Special Meeting and the adjournment
is for a period of less than 120 days from the original date of the Special
Meeting, no notice of the time and place of the adjourned meeting need be given
to shareholders other than an announcement made at the Special Meeting. Proxies
voted against the Merger and abstentions will not be voted to adjourn the
Special Meeting.
 
     The effect of any such adjournment would be to permit Bankshares to solicit
additional proxies for approval of the Merger. While such an adjournment would
not invalidate any proxies previously filed, including those filed by
shareholders voting against the Merger, it would afford Bankshares the
opportunity to solicit additional proxies in favor of the Merger.
 
                                 OTHER MATTERS
 
     The Board of Directors of Bankshares is not aware of any business to come
before the Special Meeting other than those matters described above in this
Prospectus. If, however, any other matters not now known should properly come
before the Special Meeting, the proxy holders named in the accompanying proxy
will vote such proxy on such matters as determined by a majority of the Board of
Directors of Bankshares.
 
             DATE FOR SUBMISSION OF BANCGROUP STOCKHOLDER PROPOSALS
 
     In order to be eligible for inclusion in BancGroup's proxy solicitation
materials for its 1997 annual meeting of stockholders, any stockholder proposal
to take action at such meeting must be received at BancGroup's main office at
One Commerce Street, Post Office Box 1108, Montgomery, Alabama 36192, no later

<PAGE>   79
 
     2.4 Resulting Corporation's Officers and Board.  The board of directors and
the officers of the Resulting Corporation on the Effective Date shall consist of

     2.5 Stockholder Approval.  This Agreement shall be submitted to the
shareholders of Acquired Corporation at the Stockholders Meeting to be held as
promptly as practicable consistent with the satisfaction of the conditions set
forth in this Agreement. Upon approval by the requisite vote of the shareholders
of Acquired Corporation as required by applicable Law, this Agreement shall
become effective as soon as practicable thereafter in the manner provided in
section 2.7 hereof.
 
     2.6 Further Acts.  If, at any time after the Effective Date, the Resulting
Corporation shall consider or be advised that any further assignments or
assurances in law or any other acts are necessary or desirable (i) to vest,
perfect, confirm or record, in the Resulting Corporation, title to and
possession of any property or right of Acquired Corporation or BancGroup,
acquired as a result of the Merger, or (ii) otherwise to carry out the purposes
of this Agreement, BancGroup and its officers and directors shall execute and

structure of such merger are not known at this time, and BancGroup in its
discretion will finalize such timing and structure at a later date. Acquired

                                   ARTICLE 3
 
                    CONVERSION OF ACQUIRED CORPORATION STOCK
 
     3.1 Conversion of Acquired Corporation Stock.
 
     (a) On the Effective Date, each share of common stock of Acquired
Corporation outstanding and held by Acquired Corporation's shareholders (the
"Acquired Corporation Stock"), shall be converted by operation of law and
without any action by any holder thereof into shares of BancGroup Common Stock
at a per share price of $27.39 (the "Merger Consideration") as specified below.
Specifically, each outstanding share of Acquired Corporation Stock shall
(subject to section 3.3 hereof), be converted into such number of shares of
BancGroup Common Stock equal to $27.39 divided by the Market Value. For purposes
of this Agreement, "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; provided, however, that
regardless of the actual Market Value as calculated above. Market Value shall
not be less than $29.75, nor more than $37.75. Accordingly, the maximum number
of shares of BancGroup Common Stock to be issued in the Merger shall be 645,240
(based upon a minimum Market Value of $29.75) and the minimum number of shares
of BancGroup Common Stock to be issued in the Merger shall be 508,500 (based
upon a maximum Market Value of $37.75) assuming 700,836 shares of Acquired
Corporation common stock outstanding. To the extent that the number of shares of
Acquired Corporation Stock may increase based upon the exercise of Acquired
Corporation Options or the conversion of Acquired Corporation debentures, the
aggregate number of shares of BancGroup Common
 
                                       A-2
<PAGE>   80
 
Stock to be issued in the Merger shall be increased with each share of Acquired
Corporation Stock outstanding at the Effective Date exchanged for shares of
BancGroup Common Stock equal to $27.39 divided by the Market Value.
 
     (b)(i) On the Effective Date, BancGroup shall assume all Acquired
Corporation Options outstanding, and each such option shall cease to represent a
right to acquire Acquired Corporation common stock and shall, instead, represent
the right to acquire BancGroup Common Stock on substantially the same terms
applicable to the Acquired Corporation Options except as specified below in this
section. The number of shares of BancGroup Common Stock to be issued pursuant to
such options shall equal the number of shares of Acquired Corporation common
stock subject to such Acquired Corporation Options multiplied by the Exchange
Ratio, provided that no fractions of shares of BancGroup Common Stock shall be
issued and the number of shares of BancGroup Common Stock to be issued upon the
exercise of Acquired Corporation Options, if a fractional share exists, shall
equal the number of whole shares obtained by rounding to the nearest whole
number, giving account to such fraction. The exercise price for the acquisition
of BancGroup Common Stock shall be the exercise price for each share of Acquired
Corporation common stock subject to such options divided by the Exchange Ratio,
adjusted appropriately for any rounding to whole shares that may be done. For
purposes of this Agreement, the "Exchange Ratio" shall mean the result obtained
by dividing $27.39 by the Market Value. It is intended that the assumption by
BancGroup of the Acquired Corporation Options shall be undertaken in a manner
that will not constitute a "modification" as defined in Section 424 of the Code
as to any stock option which is an "incentive stock option." Schedule 3.1 hereto
sets forth the names of all persons holding Acquired Corporation Options, the
number of shares of Acquired Corporation common stock subject to such options,
the exercise price and the expiration date of such options.
 
     (ii) 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 such 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.
 
     (c) On the Effective Date, BancGroup will assume Acquired Corporation's
Series A 7% Convertible Subordinated Debentures (the "Series A Debentures")
respecting the issuance of 64,773 shares of Acquired Corporation common stock.
Such debentures shall be convertible into shares of BancGroup Common Stock, with
each share of Acquired Corporation common stock that would have been issued upon
conversion of such debenture being convertible into such number of shares of
BancGroup Common Stock equal to one share of Acquired Corporation common stock
multiplied by the Exchange Ratio. No fractions of shares of BancGroup Common
Stock will be issued upon conversion of such debentures, and any fractions to be
issued shall be paid in cash as set forth in such debentures.
 
     3.2 Surrender of Acquired Corporation Stock.  After the Effective Date,
each holder of an outstanding certificate or certificates which prior thereto
represented shares of Acquired Corporation Stock who is entitled to receive
BancGroup Common Stock shall be entitled, upon surrender to BancGroup of their
certificate or certificates representing shares of Acquired Corporation Stock
(or an affidavit or affirmation by such holder of the loss, theft, or
destruction of such certificate or certificates in such form as BancGroup may
reasonably require and, if BancGroup reasonably requires, a bond of indemnity in
form and amount, issued by such sureties, as BancGroup may reasonably require),
to receive in exchange therefor a certificate or certificates representing the
number of whole shares of BancGroup Common Stock into and for which the shares
of Acquired Corporation Stock so surrendered shall have been converted, such
certificates to be of such denominations and registered in such names as such
holder may reasonably request. Until so surrendered and exchanged, each such
outstanding certificate which, prior to the Effective Date, represented shares
of Acquired Corporation Stock and which is to be converted into BancGroup Common
Stock shall for all purposes evidence ownership of the BancGroup Common Stock
into and for which such shares shall have been so converted, except that no
dividends or other distributions with respect to such BancGroup Common Stock
shall be made until the certificates previously representing shares of Acquired
Corporation Stock shall have been properly tendered.
 
                                       A-3
<PAGE>   81
 
     3.3 Fractional Shares.  No fractional shares of BancGroup Common Stock
shall be issued, and each holder of shares of Acquired Corporation Stock having
a fractional interest arising upon the conversion of such shares into shares of
BancGroup Common Stock shall, at the time of surrender of the certificates
previously representing Acquired Corporation Stock, be paid by BancGroup an
amount in cash equal to the Market Value of such fractional share.
 
     3.4 Adjustments.  In the event that prior to the Effective Date BancGroup
Common Stock shall be changed into a different number of shares or a different
class of shares by reason of any recapitalization or reclassification, stock
dividend, combination, stock split, or reverse stock split of the BancGroup
Common Stock, an appropriate and proportionate adjustment shall be made in the
number of shares of BancGroup Common Stock into which the Acquired Corporation
Stock shall be converted.
 
     3.5 BancGroup Stock.  The shares of Common Stock of BancGroup issued and
outstanding immediately before the Effective Date shall continue to be issued
and outstanding shares of the Resulting Corporation.
 
     3.6 Dissenting Rights.  Any shareholder of Acquired Corporation who shall
not have voted in favor of this Agreement and who has complied with the
applicable procedures set forth in the GBCC, relating to rights of dissenting
shareholders, shall be entitled to receive payment for the fair value of his
Acquired Corporation Stock. If after the Effective Date a dissenting shareholder
of Acquired Corporation fails to perfect, or effectively withdraws or loses, his
right to appraisal and payment for his shares of Acquired Corporation Stock,
BancGroup shall issue and deliver the consideration to which such holder of
shares of Acquired Corporation Stock is entitled under Section 3.1 (without
interest) upon surrender of such holder of the certificate or certificates
representing shares of Acquired Corporation Stock held by him.

             REPRESENTATIONS, WARRANTIES AND COVENANTS OF BANCGROUP
 
     BancGroup represents, warrants and covenants to and with Acquired
Corporation as follows:
 
     4.1 Organization.  BancGroup is a corporation duly organized, validly
existing and in good standing under the Laws of the State of Delaware. BancGroup
has the necessary corporate powers to carry on its business as presently
conducted and is qualified to do business in every jurisdiction in which the
character and location of the Assets owned by it or the nature of the business
transacted by it requires qualification or in which the failure to qualify
could, individually or in the aggregate, have a Material Adverse Effect.
 
     4.2 Capital Stock.
 
     (a) The authorized capital stock of BancGroup consists of (A) 44,000,000
shares of Common Stock, $2.50 par value per share, of which as of August 13,
1996, 16,264,524 shares were validly issued and outstanding, fully paid and
nonassessable and are not subject to preemptive rights (not counting additional
shares subject to issue pursuant to stock option and other plans and convertible
debentures), and (B) 1,000,000 shares of Preference Stock, $2.50 par value per
share, none of which are issued and outstanding. The shares of BancGroup Common
Stock to be issued in the Merger are duly authorized and, when so issued, will
be validly issued and outstanding, fully paid and nonassessable, will have been
registered under the 1933 Act, and will have been registered or qualified under
the securities laws of all jurisdictions in which such registration or
qualification is required, based upon information provided by Acquired
Corporation.
 
     (b) The authorized capital stock of each Subsidiary of BancGroup is validly
issued and outstanding, fully paid and nonassessable, and each Subsidiary is
wholly owned, directly or indirectly, by BancGroup.
 
     4.3 Financial Statements; Taxes.  (a) BancGroup has delivered to Acquired
Corporation copies of the following financial statements of BancGroup.
 
     (i) Consolidated balance sheets as of December 31, 1994, and December 31,
1995, and for the six months ended June 30, 1996;
 
                                       A-4
<PAGE>   82

1996;
 
     (iii) Consolidated statements of cash flows for each of the three years

with generally accepted accounting principles applied on a consistent basis
throughout the periods indicated, all as more particularly set forth in the
notes to such statements. Each of the consolidated balance sheets presents
fairly as of its date the consolidated financial condition of BancGroup and its
Subsidiaries. Except as and to the extent reflected or reserved against in such
balance sheets (including the notes thereto), BancGroup did not have, as of the
dates of such balance sheets, any material Liabilities or obligations (absolute
or contingent) of a nature customarily reflected in a balance sheet or the notes
thereto. The statements of consolidated income, shareholders' equity and changes
in consolidated financial position present fairly the results of operations and
changes in financial position of 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 six months ended
June 30, 1996, 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 these returns to be due
and all additional assessments received have been paid. The amounts recorded for
Taxes on the balance sheets provided under section 4.3(a) are, to the Knowledge
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 such 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 Contract, indenture, mortgage, deed of trust or other
material agreement or instrument to which BancGroup or any of its Subsidiaries
is a party or by which they or their Assets may be bound; will not conflict with
any provision of the restated certificate of incorporation or bylaws of

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 Acquired Corporation, or to liquidate any
Subsidiaries, subsequent to the Merger, and BancGroup intends to continue the
historic business of Acquired Corporation.
 
     4.8 Title and Related Matters.  BancGroup has good and marketable title to
all the properties, interests in properties and Assets, real and personal,

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

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 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.

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, 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

(including any interest or penalties) of Acquired Corporation accrued for or
applicable to the period ended on the dates thereof, and all years and periods
prior thereto and for which Acquired Corporation may at such dates have been

compensation). Each Acquired Corporation 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.

(nor is Acquired Corporation 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
Acquired Corporation, and no Acquired Corporation Company is in Default with
respect to any judgment, order, writ, injunction, decree, award, rule or
regulation of any court, arbitrator or governmental department, commission,
board, bureau, agency or instrumentality, which Default would have a Material
Adverse Effect on Acquired Corporation. To the Knowledge of Acquired
Corporation, each Acquired Corporation Company has complied in all material
respects with all material applicable Laws and Regulations including those
imposing Taxes, of any applicable jurisdiction and of all states,
municipalities, other political subdivisions and Agencies, in respect of the
ownership of its properties and the conduct of its business, which, if not
complied with, would have a Material Adverse Effect on Acquired Corporation.
 
     5.10 Material Contract Defaults.  No Acquired Corporation Company is in
Default in any material respect under the terms of any material Contract,
agreement, lease or other commitment which is or may be material to the
business, operations, properties or Assets, or the condition, financial or
otherwise, of such company and, to the Knowledge of Acquired Corporation, there
is no event which, with notice or lapse of time, or both, may be or become an
event of Default under any such material Contract, agreement, lease or other
commitment in respect of which adequate steps have not been taken to prevent
such a Default from occurring.
 
     5.11 No Conflict with Other Instrument.  The consummation of the
transactions contemplated by this Agreement will not result in the breach of any

provision of the charter or bylaws of any Acquired Corporation Company.

the business conducted by it or in which such Agency has raised any material
question concerning the condition, financial or otherwise, of such company.

     5.14 Absence of Material Adverse Change.  To the Knowledge of Acquired
Corporation, since the date of the most recent balance sheet provided under

had, or are reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on any Acquired Corporation Company.
 
     5.15 Insurance.  Each Acquired Corporation Company has in effect insurance
coverage and bonds with reputable insurers which, in respect to amounts, types
and risks insured, management of Acquired Corporation reasonably believes to be
adequate for the type of business conducted by such company. No Acquired
Corporation Company is liable for any material retroactive premium adjustment.
All insurance policies and bonds are valid, enforceable and in full force and
effect, and no Acquired Corporation Company has received any notice of any
material premium increase or cancellation with respect to any of its insurance
policies or bonds. Within the last three years, no Acquired Corporation Company
has been refused any insurance coverage which it has sought or applied for, and
it has no reason to believe that existing insurance coverage cannot be renewed
as and when the same shall expire, upon terms and conditions as favorable as
those presently in effect, other than possible increases in premiums that do not
result from any extraordinary loss experience. All policies of insurance
presently held or policies containing substantially equivalent coverage will be
outstanding and in full force with respect to each Acquired Corporation Company
at all times from the date hereof to the Effective Date.
 
     5.16 Pension and Employee Benefit Plans.

each Acquired Corporation Company have been established in compliance with, and
such plans have been operated in material compliance with, all applicable Laws.

within the meaning of section 3(2) of ERISA or any other retirement plan other
than the Dalton/Whitfield Bank & Trust 401(k) Profit Sharing 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 Acquired Corporation, no employee benefit plan, any trust
created thereunder or any trustee or administrator thereof has engaged in a
"prohibited transaction," as defined in section 4975 of the Code, which may have
a Material Adverse Effect on the condition, financial or otherwise, of any
Acquired Corporation Company.
 
     (b) To the Knowledge of Acquired Corporation, no amounts payable to any
employee of any Acquired Corporation Company will fail to be deductible for
federal income tax purposes by virtue of Section 280G of the Code and
regulations thereunder.

respect of any such shares.

and the transactions contemplated by this Agreement have been carried on by
Acquired Corporation directly with BancGroup and without the intervention of any
other person, either as a result of any act of Acquired Corporation, or
otherwise, in such manner as to give rise to any valid claim against Acquired
Corporation for a finder's fee, brokerage commission or other like payment.
 
     5.19 Approval of Agreements.  The board of directors of Acquired
Corporation has approved this Agreement and the transactions contemplated by
this Agreement and has authorized the execution and delivery by Acquired

this Agreement or in any such statement or certificate not misleading.
 
     5.21 Registration Statement.  At the time the Registration Statement

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

the business of Acquired Corporation, its Assets, properties, operations, and
capital stock or to information furnished in writing by Acquired Corporation 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 Acquired
Corporation have been calculated in accordance with prudent and customary
banking practices and are adequate in all material respects to reflect the risk
inherent in the loans of Acquired Corporation. Acquired Corporation has no
Knowledge of any fact which is likely to require a future material increase in
the provision for loan losses or a material decrease in the loan loss reserve
reflected in such financial statements. Each loan reflected as an Asset on the
financial statements of Acquired Corporation is the legal, valid and binding
obligation of the obligor of each loan, enforceable in accordance with its terms
subject to the effect of bankruptcy, insolvency, reorganization, moratorium, or
other similar laws relating to creditors' rights generally and to general

Acquired Corporation Company has not complied with all regulations and

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

of the total fair market value of Acquired Corporation common stock outstanding
immediately before the Merger.

Company is pending before the National Labor Relations Board. Relations between
management of each Acquired Corporation Company and the employees are amicable
and there have not been, nor to the Knowledge of Acquired Corporation, are there
presently, any attempts to organize employees, nor to the Knowledge of Acquired
Corporation, are there plans for any such attempts.

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

     Corporation:
 
             (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, and a consolidated statement of financial condition of
        BancGroup as of the end of such quarterly period, setting forth in each
        case in comparative form figures for the corresponding periods ending in

        regular and periodic reports as BancGroup may file with the SEC or any
        other Agency; and
 
                                      A-14
<PAGE>   92
 
             (iv) With reasonable promptness, such additional financial data as
        Acquired Corporation may reasonably request.
 
          (d) No Control of Acquired Corporation by BancGroup.  Notwithstanding
     any other provision hereof, until the Effective Date, the authority to
     establish and implement the business policies of Acquired Corporation shall
     continue to reside solely in Acquired Corporation'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 Acquired Corporation Company shall, at BancGroup's option, either
     become employees of the Resulting Corporation or its Subsidiaries or be
     entitled to severance benefits in accordance with Colonial Bank's severance
     policy as of the date of this Agreement. All employees of any Acquired
     Corporation Company who become employees of the Resulting Corporation or
     its Subsidiaries on the Effective Date shall be entitled, to the extent
     permitted by applicable Law, to participate in all benefit plans of
     Colonial Bank to the same extent as Colonial Bank employees except as
     stated otherwise in this section. Employees of any Acquired Corporation
     Company who become employees of the Resulting Corporation or its
     Subsidiaries shall be allowed to participate as of the Effective Date in
     the medical and dental benefits plan of Colonial Bank as new employees of
     Colonial Bank, and the time of employment of such employees who are
     employed at least 30 hours per week with any Acquired Corporation Company
     at Closing shall be counted as employment under such dental and medical
     plans of Colonial Bank for purposes of calculating any 30 day waiting
     period and pre-existing condition limitations. To the extent permitted by
     applicable Law, the period of service with the appropriate Acquired
     Corporation Company of all employees who become employees of the Resulting
     Corporation or its Subsidiaries on the Effective Date shall be recognized
     only for vesting and eligibility purposes under Colonial Bank's benefit
     plans. In addition, if the Effective Date falls within an annual period of
     coverage under any group health plan or group dental plan of the Resulting
     Corporation and its Subsidiaries, each such Acquired Corporation Company
     employee shall be given credit for covered expenses paid by that employee
     under comparable employee benefit plans of the Acquired Corporation Company
     during the applicable coverage period through the Effective Date towards
     satisfaction of any annual deductible limitation and out-of-pocket maximum
     that may apply under that group health plan or group dental plan of the
     Resulting Corporation and its Subsidiaries. BancGroup shall be responsible
     for the provision of any continuation coverage to which an employee of any
     Acquired Corporation Company becomes entitled under section 4980B of the
     Code by virtue of a qualifying event occurring on or before the Effective
     Date until the earliest date that the coverage would cease under section
     4980B(f)(2)(B) of the Code, with the understanding for purposes of making
     that determination that the Colonial Bank medical and dental plans are
     successor plans within the meaning of section 1.162-26, Q&A 38, Proposed
     Treasury Regulations.
 
          (g) Indemnification.  (i) For a period of two years after the
     Effective Date, BancGroup shall indemnify, defend and hold harmless the
     present and former directors, officers, employees and agents of the
     Acquired Corporation Companies (each, an "Indemnified Party") against all
     Liabilities arising out of actions or omissions occurring at or prior to
     the Effective Date (including the transactions contemplated by this
     Agreement) to the full extent permitted under Georgia Law and by Acquired
     Corporation's Articles of Incorporation and Bylaws as in effect on the date
     hereof including provisions relating to advances of expenses incurred in
     the defense of any Litigation.
 
             (ii) BancGroup shall use its reasonable efforts to maintain
        Acquired Corporation's existing director's and officers' liability
        insurance policy (or a policy, including BancGroup's existing policy,
        providing at least comparable coverage) covering persons who are
        currently covered by such insurance for a period of three years after
        the Effective Date on terms no less favorable than those in effect on
        the date hereof, provided that BancGroup shall not be obligated to make
        annual premium payments in respect of such policy (or coverage replacing
        such policy) which exceed, for the portion
 
                                      A-15
<PAGE>   93
 
        related to Acquired Corporation's directors and officers, 150% of the
        annual premium payments on Acquired Corporation's current policy in
        effect as of the date of this Agreement.
 
             (iii) Any Indemnified Party wishing to claim indemnification under
        paragraph (i), upon learning of any such Liability or Litigation, shall
        promptly notify BancGroup thereof. In the event of any such Litigation
        (whether arising before or after the Effective Date), (1) BancGroup
        shall have the right to assume the defense thereof and BancGroup shall
        not be liable to such Indemnified Party 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 substantive 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
        all reasonable fees and expenses of such counsel for the Indemnified
        Parties promptly as statements therefor are received; provided, however,
        that BancGroup shall be obligated pursuant to this paragraph (iii) to
        pay for only one firm of counsel for all Indemnified Parties in any
        jurisdiction, (2) the Indemnified Parties will cooperate in the defense
        of any such Litigation, and (3) BancGroup shall not be liable for any
        settlement effected without its prior written consent; and provided
        further that BancGroup shall not have any obligation hereunder to any
        Indemnified Party when and if a court of competent jurisdiction shall
        determine, and such determination shall have become final, that the
        indemnification of such Indemnified Party in the manner contemplated
        hereby is prohibited by applicable Law.
 
             (iv) If BancGroup or any of its successors or assigns shall
        consolidate with or merge into any other Person and shall not be the
        continuing or surviving Person of such consolidation or merger or shall

following corporate actions:
 
          (1) Consummation of a plan of merger to which the corporation is a
     party:

                                       B-1
<PAGE>   108
 
             (B) Creates, alters, or abolishes a right in respect of redemption,
        including a provision respecting a sinking fund for the redemption or

        shares to acquire shares or other securities;
 
             (D) Excludes or limits the right of the shares to vote on any

        rights;
 
             (E) Reduces the number of shares owned by the shareholder to a
        fraction of a share if the fractional share so created is to be acquired

     extent that Article 9 of this chapter, the articles of incorporation,
     bylaws, or a resolution of the board of directors provides that voting or
     nonvoting shareholders are entitled to dissent and obtain payment for their
     shares.
 
     (b) A shareholder entitled to dissent and obtain payment for his shares
under this article may not challenge the corporate action creating his
entitlement unless the corporate action fails to comply with procedural
requirements of this chapter or the articles of incorporation or bylaws of the
corporation or the vote required to obtain approval of the corporate action was
obtained by fraudulent and deceptive means, regardless of whether the
shareholder has exercised dissenter's rights.
 
     (c) Notwithstanding any other provision of this article, there shall be no
right of dissent in favor of the holder of shares of any class or series which,
at the record date fixed to determine the shareholders entitled to receive
notice of and to vote at a meeting at which a plan of merger or share exchange
or a sale or exchange of property or an amendment of the articles of
incorporation is to be acted on, were either listed on a national securities
exchange or held of record by more than 2,000 shareholders, unless:
 
          (1) In the case of a plan of merger or share exchange, the holders of
     shares of the class or series are required under the plan of merger or
     share exchange to accept for their shares anything except shares of the
     surviving corporation or another publicly held corporation which at the
     effective date of the merger or share exchange are either listed on a
     national securities exchange or held of record by more than 2,000
     shareholders, except for scrip or cash payments in lieu of fractional
     shares; or
 
          (2) The articles of incorporation or a resolution of the board of
     directors approving the transaction provides otherwise.
 
SECTION 14-2-1303.  DISSENT BY NOMINEES AND BENEFICIAL OWNERS.
 
     A record shareholder may assert dissenters' rights as to fewer than all the
shares registered in his name only if he dissents with respect to all shares
beneficially owned by any one beneficial shareholder and notifies the
corporation in writing of the name and address of each person on whose behalf he
asserts dissenters' rights. The rights of a partial dissenter under this Code
section are determined as if the shares as to which he dissents and his other
shares were registered in the names of different shareholders.

     (a) A dissenter may notify the corporation in writing of his own estimate
of the fair value of his shares and amount of interest due, and demand payment

          (1) The dissenter believes that the amount offered under Code Section

     due is incorrectly calculated; or
 
          (2) The corporation, having failed to take the proposed action, does
     not return the deposited certificates or release the transfer restrictions
     imposed on uncertificated shares within 60 days after the date set for
     demanding payment.
 
     (b) A dissenter waives his or her right to demand payment under this Code

this Code section within 30 days after the corporation offered payment for his
or her shares, as provided in Code Section 14-2-1325.

PART 3.  JUDICIAL APPRAISAL OF SHARES
 
SECTION 14-2-1330.  COURT ACTION.
 
     (a) If a demand for payment under Code Section 14-2-1327 remains unsettled,
the corporation shall commence a proceeding within 60 days after receiving the
payment demand and petition the court to determine the fair value of the shares
and accrued interest. If the corporation does not commence the proceeding within
the 60 day period, it shall pay each dissenter whose demand remains unsettled
the amount demanded.
 
     (b) The corporation shall commence the proceeding, which shall be a nonjury
equitable valuation proceeding, in the superior court of the county where a
corporation's registered office is located. If the surviving corporation is a
foreign corporation without a registered office in this state, it shall commence
the proceeding in the county in this state where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
corporation was located.
 
     (c) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the proceeding, which
shall have the effect of an action quasi in rem against their shares. The
corporation shall serve a copy of the petition in the proceeding upon each
dissenting shareholder who is a resident of this state in the manner provided by
law for the service of a summons and complaint, and upon each nonresident
dissenting shareholder either by registered or certified mail or by publication,
or in any other manner permitted by law.
 
     (d) The jurisdiction of the court in which the proceeding is commenced
under subsection (b) of this Code section is plenary and exclusive. The court
may appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value. The appraisers have the powers described
in the order appointing them or in any amendment to it. Except as otherwise
provided in this chapter, Chapter 11 of Title-9, known as the "Georgia Civil
Practice Act," applies to any proceeding with respect to dissenters' rights
under this chapter.
 
     (e) Each dissenter made a party to the proceeding is entitled to judgment
for the amount which the court finds to be the fair value of his shares, plus
interest to the date of judgment.
 
SECTION 14-2-1331.  COURT COSTS AND COUNSEL FEES.
 
     (a) The court in an appraisal proceeding commenced under Code Section
14-2-1330 shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court, but not
including fees and expenses of attorneys and experts for the respective parties.
The court shall assess the costs against the corporation, except that the court
may assess the costs against all or some of the dissenters, in amounts the court
finds equitable, to the extent the court finds the dissenters acted arbitrarily,
vexatiously, or not in good faith in demanding payment under Code Section
14-2-1327.
 
     (b) The court may also assess the fees and expenses of attorneys and
experts for the respective parties, in amounts the court finds equitable:
 
          (1) Against the corporation and in favor of any or all dissenters if
     the court finds the corporation did not substantially comply with the
     requirements of Code Sections 14-2-1320 through 14-2-1327; or
 
          (2) Against either the corporation or a dissenter, in favor of any
     other party, if the court finds that the party against whom the fees and
     expenses are assessed acted arbitrarily, vexatiously, or not in good faith
     with respect to the rights provided by this article.
 
     (c) If the court finds that the services of attorneys for any dissenter
were of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to these attorneys reasonable fees to be paid out of the amounts
awarded the dissenters who were benefitted.

SECTION 14-2-1332.  LIMITATION OF ACTIONS.
 
     No action by any dissenter to enforce dissenters' rights shall be brought
more than three years after the corporate action was taken, regardless of
whether notice of the corporate action and of the right to dissent was given by
the corporation in compliance with the provisions of Code Section 14-2-1320 and
Code Section 14-2-1322.

October 18, 1996
 
Board of Directors
D/W Bankshares, Inc.
401 South Thornton Avenue
Dalton, Georgia 30720
 
Dear Directors:
 
     T. Stephen Johnson & Associates, Inc., Roswell, Georgia ("TSJ&A") has been
asked to render an opinion as to the fairness from a financial point of view of
the consideration to be received by the shareholders of D/W Bankshares, Inc.
("Bankshares") in connection with the proposed merger of Bankshares with and
into The Colonial BancGroup, Inc. ("BancGroup"), pursuant to an Agreement and
Plan of Merger (the "Merger Agreement") dated as of September 12, 1996 (the
"Merger"). The Merger Agreement calls for each outstanding share of Bankshares'
common stock to be converted into the right to receive that number of shares of
BancGroup's common stock equal to $27.39 divided by the Market Value of that
stock as defined in the Merger Agreement.
 
     TSJ&A is an investment banking and consulting firm that specializes in the
valuation of closely-held corporations and provides fairness opinions as part of
its practice. Because of its prior experience in the appraisal of Southeastern
financial institutions involved in mergers, it has developed an expertise in
fairness opinions related to the securities of Southeastern financial
institutions.
 
     In performing its analysis, TSJ&A relied upon and assumed without
independent verification, the accuracy and completeness of all information
provided to it. TSJ&A has not performed any independent appraisal or evaluation
of the assets of Bankshares or of BancGroup or any of its subsidiaries. As such,
TSJ&A does not express an opinion as to the fair market value of Bankshares. The
opinion of financial fairness expressed herein is necessarily based on market,
economic and other relevant considerations as they exist and can be evaluated as
of October 15, 1996.
 
     In arriving at its opinion, TSJ&A reviewed and analyzed audited and
unaudited financial information regarding Bankshares and BancGroup, the Merger,
the Merger Agreement, national, state and local peer group information as well
as publicly available information regarding actual comparable transactions.
 
     The merger consideration to be received by Bankshares' shareholders is set
at $27.39 per share converted into the right to receive BancGroup common stock,
subject to the Market Value of BancGroup stock, as defined in the Merger
Agreement, being not less than $29.75 per share nor more than $37.75 per share.
BancGroup's stock has consistently traded within this range during the last 52
weeks. Options outstanding at the effective date of the merger will be converted
into options to purchase BancGroup stock on substantially the same terms,
subject to the resulting exchange ratio. Bankshares' Series A 7% convertible
subordinated debentures will be converted into BancGroup stock based upon the
conversion agreement and the resulting exchange ratio.
 
     There are currently 700,836 shares of common stock outstanding with a book
value as of September 30, 1996 of $15.59 per share. There are options
outstanding for a total of 46,750 shares with an average exercise price of $9.09
per share. There are debentures outstanding convertible into 64,772 shares at a
conversion price of $22.00 per share. On a fully converted basis, there would be
812,358 shares outstanding with a book value of $15.73 per share. Earnings for
the first nine months totaled $1.21 million or $1.73 per share; $1.61 per share
fully diluted (782,134 shares outstanding). Earnings for the last twelve months
totaled $1.40 million or $2.00 per share; $1.79 per share fully diluted.
 
     The deal value per share has been established at $27.39. This deal value is
1.757 times current book value and 1.741 times fully converted book value. This
deal value is 13.694 times last twelve months earnings per share and 15.283
times fully diluted earnings per share.
 
                                       C-1
<PAGE>   114
 
     TSJ&A reviewed the Merger as of October 11, 1996, for the purpose of
determining purchase premiums which could be used in comparing the Merger with
other announced transactions. TSJ&A reviewed the purchase premiums paid in 74
transactions that were announced between July 1, 1995 and October 11, 1996
involving selling commercial banks headquartered in the states of Alabama,
Florida, Georgia and Tennessee. Of these transactions, nine involved selling
institutions that have been determined to be comparable transactions. They
include institutions representing commercial bank institutions with total assets
between $100 million and $200 million. A listing of these transactions is
attached. The purchase premiums in the Merger rank within the range of purchase
premiums paid in the comparable transactions. On average, the nine comparable
transactions reported an announced deal price to book value of 1.646 times and
an announced deal price to earnings of 14.36 times.
 
     Therefore, in consideration of the above, it is the opinion of TSJ&A that,
based on the structure of the Merger and the analyses that have been performed,
the consideration to be received by the shareholders of Bankshares is fair from
a financial point of view.
 
Sincerely,
 
T. Stephen Johnson & Associates, Inc.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.         INDEMNIFICATION OF DIRECTORS AND OFFICERS.

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

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

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

<PAGE>   117

standard of conduct has been met.  Expenses (including attorneys' fees)
incurred by an officer or director in defending a proceeding may be advanced by
the corporation prior to the final disposition of the proceeding upon receipt
of an undertaking by or on behalf of the director or officer to repay the
advance if it is ultimately determined that he is not entitled to be
indemnified by the corporation.  Expenses (including attorneys' fees) incurred
by other employees and agents may be advanced by the corporation upon terms and
conditions deemed appropriate by the board of directors.

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

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

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

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

         The Indemnification Agreements impose upon BancGroup the burden of
proving that the director or officer is not entitled to indemnification in any
particular case, and the Indemnification Agreements negate certain presumptions
which might otherwise be drawn against a director or officer in certain
circumstances.  Further, the Indemnification Agreements provide that if
BancGroup pays a director or officer pursuant to an Indemnification Agreement,
BancGroup will be subrogated to such director's or officer's rights to recover
from third parties.

<PAGE>   118


         The Indemnification Agreements stipulate that a director's or
officer's rights under such contracts are not exclusive of any other indemnity
rights a director or officer may have; however, the Indemnification Agreements
prevent double payment.  The Indemnification Agreements require the maintenance
of directors' and officers' liability insurance if such insurance can be
maintained on terms, including rates, satisfactory to BancGroup.

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

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

         (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




                                       10
<PAGE>   122

                          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 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;

                                  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;

                          (iii)   To include any material information with

                                  previously disclosed in the Registration
                                  Statement or any material change to such
                                  information in the Registration Statement;

                 (2)      That, for the purpose of determining any liability
                          under the Securities Act of 1933, each such
                          post-effective amendment shall be deemed to be a new
                          registration relating to the securities offered
                          therein, and the offering of such securities at that
                          time shall be deemed to be the initial bona fide
                          offering thereof.

                 (3)      To remove from registration by means of a
                          post-effective amendment any of the securities being
                          registered which remain unsold at the termination of

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

         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 D/W Bankshares,
                 Inc. ("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 September 12, 1996
(the "Agreement"), by and between the Company and D/W Bankshares, Inc. and the
issuance by the Company of its Common Stock pursuant to stock options being
assumed by the Company in accordance with the Agreement.  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

<PAGE>   3

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
person whose consent is required pursuant to Section 7 of the Securities Act of
1933, as amended.

                                Sincerely yours,

         Re:  Tax Opinion

Gentlemen:

         We have acted as counsel to The Colonial BancGroup, Inc., a Delaware
corporation ("BancGroup"), in connection with the merger of D/W Bankshares,
Inc., a Georgia corporation ("Bankshares"), with and into BancGroup, pursuant
to the Agreement and Plan of Merger, dated as of September 12, 1996, (the
"Agreement") by and between BancGroup and Bankshares.  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 Bankshares
and BancGroup to be filed with the Securities and Exchange Commission.  We have
assumed that the merger will be consummated on the Effective Date pursuant to
the terms and conditions set forth in the

<PAGE>   3

November 1, 1996
Page 27


Agreement and as described in the preliminary joint proxy statement-prospectus.
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 Dalton/Whitfield Bank & Trust (the "Bank"), a wholly owned
subsidiary of Bankshares, except that the Bank will be merged into Colonial
Bank on or after the merger.

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

         (3)     Bankshares 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 Bankshares common stock outstanding
immediately before the merger.

         (4)     As a result of the merger, each share of the issued and
outstanding Bankshares 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, Bankshares 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 a Bankshares shareholder will be approximately equal to the fair
market value of the Bankshares stock exchanged therefor.

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

         (8)     Bankshares and the Bank are 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 Bankshares with and into BancGroup in accordance
with the terms of the Agreement will constitute a reorganization within the
meaning of Section 368(a)(1)(A) of the Code.  Bankshares and Bancgroup will
each be a "party to a reorganization" under Section 368(b) of the Code.

         (2)     No gain or loss will be recognized by Bankshares upon the
transfer of its assets and liabilities to BancGroup.  Sections 357(a) and
361(a) of the Code.  No gain or loss will be recognized by BancGroup upon
receipt of the assets and liabilities of Bankshares.  Section 1032(a) of the
Code.

         (3)      The basis of the assets of Bankshares acquired by BancGroup
will be the same as the basis of the assets in the hands of Bankshares
immediately prior to the Merger.  Section 362(b) of the Code.

         (4)     The holding period of the assets of Bankshares in the hands of
BancGroup will include the period during which such assets were held by
Bankshares.  Section 1223(2) of the Code.

         (5)     A Bankshares shareholder who exchanges shares of Bankshares
stock solely for shares of BancGroup common stock as described in the Agreement
will not recognize gain or loss.  Section 354 of the Code.

         (6)     A Bankshares debenture holder whose debentures are assumed by
BancGroup will not recognize gain or loss.  Section 354 of the Code.

         (7)     A dissenting Bankshares 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 Bankshares 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 Bankshares stock
surrendered.  Section 1001 of the Code.  Such gain or loss will be capital gain
or loss if the Bankshares shares are capital assets in the hands of the
shareholder.

         (8)     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

<PAGE>   5

November 1, 1996
Page 29


whether a dissenting Bankshares 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, 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).

         (9)     The tax basis of the BancGroup common stock received by a
Bankshares shareholder will be the same as the adjusted tax basis of the shares
of Bankshares 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.

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

         (11)    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, 1996 - 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.

         This opinion is being rendered solely to the parties to whom it is
addressed.  This opinion may not be relied upon nor distributed to any other
person without the written consent of our Firm.  We hereby consent to the
reference to our Firm in, and to the filing of this opinion as an exhibit to,
the joint proxy statement-prospectus.

                               Very truly yours,
