To the Holders of First Southern Common Stock:

     You are cordially invited to attend a Special Meeting of Shareholders (the
"Meeting") of First Southern Bancshares, Inc. ("FSB"), to be held at Big Miller
Grove Baptist Church, 3800 Big Miller Grove Way, Lithonia, Georgia on
_______________ 1997, at 4:00 p.m. local time, notice of which is enclosed.

     At the Meeting, you will be asked to consider and vote on a proposal to
approve an Agreement and Plan of Merger (the "Agreement") entered into with
Citizens Bancshares Corporation ("CBC") pursuant to which FSB will merge (the
"Merger") with CBC. As a result of the Merger, each share of FSB common stock
("FSB Common Stock") issued and outstanding will be converted into and exchanged
for the right to receive 1.508 shares of CBC common stock ("CBC Common Stock").

     The accompanying Proxy Statement/Prospectus includes a description of the
proposed Merger and also provides other specific information concerning the
Meeting and CBC Common Stock.

     The Merger has been approved unanimously by your Board of Directors and is
recommended by the Board to you for approval.  Each member of the Board of
Directors has agreed to vote all FSB shares beneficially owned by such member in
favor of the Merger.  Consummation of the Merger is subject to certain
conditions, including shareholder approval of FSB and regulatory approvals.

     APPROVAL OF THE AGREEMENT REQUIRES THE AFFIRMATIVE VOTE OF A MAJORITY OF
THE SHARES OF FSB COMMON STOCK ENTITLED TO VOTE AT THE MEETING.  CONSEQUENTLY, A
FAILURE TO VOTE WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE AGREEMENT.

     Accordingly, whether or not you plan to attend the Meeting, you are urged
to complete, sign, and return promptly the enclosed proxy card. If you attend
the Meeting, you may vote in person if you wish, even if you previously have
returned your proxy card. The proposed Merger is a significant transaction for
FSB, and your vote on this matter is of great importance.  ON BEHALF OF THE
BOARD OF DIRECTORS, I URGE YOU TO VOTE FOR APPROVAL OF THE MERGER BY MARKING THE
ENCLOSED PROXY CARD "FOR" THE MERGER.

                                    Sincerely,


                                    James E. Young

     2. Other Business.  To transact such other business as may properly come
before the Meeting, including adjourning or postponing the Meeting to permit, if

                         842,374 SHARES OF COMMON STOCK

                         _____________________________

     This Proxy Statement/Prospectus (this "Proxy Statement/Prospectus") is
being furnished to holders of common stock, par value $5.00 per share ("FSB
Common Stock"), of First Southern Bancshares, Inc., a Georgia corporation
("FSB"), in connection with the solicitation of proxies by the Board of
Directors of FSB for use at a special meeting of such holders to be held on
________, _________, 1997, commencing at 4:00 p.m., local time, and at any
adjournment or postponement thereof (the "FSB Meeting"). At the FSB Meeting,
holders of FSB Common Stock will be asked to consider and vote upon a proposal
to approve the Agreement and Plan of Merger, dated as of October 1, 1997, by and
between Citizens Bancshares Corporation, a Georgia corporation ("CBC") and FSB
(the "Agreement"), and the transactions contemplated thereby, pursuant to which,
among other things, FSB will merge with CBC (the "Merger"). A copy of the
Agreement is attached hereto as Appendix A and is incorporated herein by
reference.

     Pursuant to the Agreement, upon consummation of the Merger, except as
described herein, each issued and outstanding share of FSB Common Stock will be
converted into 1.508 shares (the "Exchange Ratio") of common stock, par value
$1.00 per share, of CBC ("CBC Common Stock"). See "The Merger."  Any options to
purchase FSB Common Stock pursuant to stock options (the "FSB Options")
remaining unexercised upon consummation of the Merger will become options to
purchase an adjusted number of shares of CBC Common Stock at an adjusted
exercise price, both of which are computed in accordance with the Exchange
Ratio. See "The Merger -- Conversion of FSB Options."  Each holder of FSB Common
Stock or FSB Options who would otherwise be entitled to receive a fraction of a
share of CBC Common Stock (after taking into account all of a shareholder's
certificates) will receive, in lieu thereof, the equivalent cash value of such
fraction of a share, without interest. See "The Merger -- Description of the
Merger."  In addition, the Merger Agreement permits FSB to declare and pay its
regular annual cash dividend to its shareholders in an amount up to $.05 per
share.
<PAGE>
 
     Consummation of the Merger is subject to several conditions, including,
among others, the affirmative vote to approve the Agreement by the holders of a
majority of the outstanding shares of FSB Common Stock entitled to vote at the
FSB Meeting and the approval of appropriate regulatory authorities. See "The
Merger -- Conditions Precedent to the Merger."

     T. Stephen Johnson & Associates, Inc. has rendered an opinion to FSB that
the consideration as provided in the Agreement is fair, from a financial point
of view, to the holders of FSB Common Stock.  See "The Merger -- Fairness
Opinion."

     THE FSB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF
FSB VOTE TO APPROVE THE AGREEMENT.  FAILURE TO VOTE IS EQUIVALENT TO VOTING
AGAINST THE MERGER AGREEMENT.

    FSB shareholders should note that employees, certain members of management
and directors of FSB have certain interests in, and may derive certain benefits
as a result of, the Merger that are in addition to their interests, if any, as
shareholders of FSB generally.  See "The Merger -- Interests of Certain Persons
in the Merger."

     This Proxy Statement/Prospectus also constitutes a prospectus of CBC with
respect to the shares of CBC Common Stock issuable to shareholders of FSB upon
consummation of the Merger. CBC has supplied all information contained in this
Proxy Statement/Prospectus relating to CBC and its subsidiary, and FSB has
supplied all information contained in this Proxy Statement/Prospectus relating
to FSB and its subsidiaries.

     This Proxy Statement/Prospectus is included as part of a Registration
Statement on Form S-4 (the "Registration Statement") filed with the Securities
and Exchange Commission (the "SEC") by CBC relating to the registration under
the Securities Act of 1933, as amended (the "Securities Act"), of up to 842,374
shares of CBC Common Stock to be issued in connection with the Merger.

     This Proxy Statement/Prospectus, Notice of Special Meeting, and the
accompanying proxy card for the FSB Meeting are first being sent to the
shareholders of FSB on or about __________, 1997.

   THE SECURITIES OFFERED HEREBY ARE NOT DEPOSITS, SAVINGS ACCOUNTS OR OTHER
       OBLIGATIONS OF A DEPOSITORY INSTITUTION AND ARE NOT INSURED BY THE
               FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER

  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
       EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
         COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
            ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT/PROSPECTUS.
                       ANY REPRESENTATION TO THE CONTRARY
                             IS A CRIMINAL OFFENSE.

     The date of this Proxy Statement/Prospectus is _______________, 1997.

                                    SUMMARY

    The following is a summary of certain information relating to the FSB
Meeting, the proposed Merger, and the shares of CBC Common Stock to be issued
upon consummation of the Merger.  This summary does not purport to be complete
and is qualified in its entirety by the more detailed information appearing
elsewhere or incorporated by reference in this Proxy Statement/Prospectus.
Shareholders are urged to read carefully the entire Proxy Statement/Prospectus,
including the Appendices.  As used in this Proxy Statement/Prospectus, the terms
"CBC" and "FSB" refer to those entities, respectively, and, where the context
requires, to those entities and their respective subsidiaries.

     Certain statements contained or incorporated by reference in this Proxy
Statement/Prospectus are "forward looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995, such as statements relating to
financial results, plans for future business development activities, capital
spending or financing sources, capital structure and the effects of regulation
and competition and are thus prospective.  Such forward looking statements are
subject to risks, uncertainties and other factors which could cause actual
results to differ materially from future results expressed or implied by such
forward looking statements.  Potential risks and uncertainties include, but are
not limited to, economic conditions, competition and other uncertainties
detailed from time to time in CBC's and FSB's filings with the SEC.

THE PARTIES

    CBC.  CBC is a bank holding company registered under the Federal Bank
Holding Company Act of 1956, as amended (the "BHC Act") and is headquartered in

approximately $116.3 million and total shareholders' equity of approximately $10
million.

    CBC was incorporated in 1972 under the laws of Georgia and is regulated by
the Board of Governors of the Federal Reserve Board (the "Federal Reserve") and
the Georgia Department of Banking and Finance (the "Georgia Department").  CBC's
principal executive offices are located at 175 John Wesley Dobbs Avenue, N.E.
and its telephone number at such address is (404) 659-5959.

    FSB.  FSB is a bank holding company registered under the BHC Act and is
headquartered in Lithonia, Georgia.  FSB has one banking subsidiary, First
Southern Bank, and one nonbank subsidiary, FSB Mortgage Services, Inc.  FSB
engages in retail and commercial banking and related services with three offices
in the Atlanta Metropolitan Area.  As of June 30, 1997, FSB had total

SPECIAL MEETING OF FSB SHAREHOLDERS

    The FSB Meeting will be held at 4:00 p.m., local time, on ____________,
1997, at Big Miller Grove Baptist Church, 3800 Big Miller Grove Way, Lithonia,
Georgia, for the purpose of considering and voting on approval of the Agreement
and transacting such other business as may properly come before the meeting or
any adjournment thereof.  See "The FSB Meeting."

    Only holders of record of FSB Common Stock at the close of business on
____________, 1997 (the "Record Date"), will be entitled to vote at the FSB
Meeting.  Approval of the Agreement requires the affirmative vote of a majority
of the shares of FSB Common Stock entitled to vote at the FSB Meeting.  As of
the Record Date, there were 553,603 shares of FSB Common Stock outstanding and
entitled to vote.

    As of the Record Date, the directors and executive officers of FSB
beneficially owned 111,757 shares (or approximately 21.12% of the outstanding
shares) of FSB Common Stock.  Each member of the Board of Directors of FSB has
agreed to vote those shares of FSB Common Stock beneficially owned by such
member in favor of the Merger.

    As of the Record Date, the directors and executive officers of CBC
beneficially owned [NO] shares of FSB Common Stock.

THE MERGER; EXCHANGE RATIO

    The Agreement provides for FSB to merge with CBC, with CBC being the
surviving corporation of the Merger.  At the Effective Time, each share of FSB
Common Stock then issued and outstanding will be converted into 1.508 shares of
CBC Common Stock (the "Exchange Ratio"), with cash to be paid in lieu of any
resulting fractional shares of CBC Common Stock.  Each share of CBC Common Stock
outstanding prior to the Merger will continue to be outstanding after the
Effective Time.  See "The Merger - General."

REASONS FOR THE MERGER

    FSB's Board of Directors has unanimously approved the Merger and the
Agreement and has determined that the Merger is fair to, and in the best
interests of, FSB and its shareholders.  Accordingly, FSB's Board of Directors
unanimously recommends that FSB's shareholders vote FOR approval of the
Agreement.  Each member of the FSB Board of Directors has agreed to vote such
member's shares of FSB Common Stock in favor of the Agreement.  The FSB Board of
Directors believes that the Merger will enable holders of FSB Common Stock to
realize increased value over time as part of the combination with CBC.  The FSB
Board further believes the combined company will have greater earnings and
expansion potential than either FSB or CBC would have individually.  The Merger
may also enable FSB shareholders to participate in opportunities for
appreciation of CBC Common Stock as a result of being part of a larger banking
franchise.  See "The Merger - Background of and Reasons for the Merger."


                                       5

FAIRNESS OPINION

    T. Stephen Johnson & Associates, Inc. has rendered an opinion to FSB that,
based on and subject to the procedures, matters and limitations described in its
opinion and such other matters as it considered relevant, as of the date of its
opinion, the terms of the Merger are fair, from a financial point of view, to
the shareholders of FSB. Such opinion is attached as Appendix B to this Proxy
Statement/Prospectus.  Shareholders are urged to read the opinion in its
entirety for a description of the procedures followed, matters considered, and
limitations on the reviews undertaken in connection with such opinion.  See "The
Merger - Fairness Opinion."

EFFECTIVE TIME

    Subject to the conditions to the obligations of the parties to effect the
Merger, the Merger will become effective upon the filing of the Certificate of
Merger with the Georgia Secretary of State. Unless otherwise agreed upon by CBC
and FSB, and subject to the conditions to the obligations of the parties to
effect the Merger, the parties will use their reasonable efforts to cause the
Effective Time to occur on the fifth business day following the last to occur:
(i) the effective date (including the expiration of any applicable waiting
period) of the last federal or state regulatory approval required for the
Merger; or (ii) the date on which the Agreement is approved by the requisite
vote of FSB shareholders. See "The Merger - Effective Time of the Merger", 
"-Conditions to Consummation of the Merger, " and "- Waiver, Amendment, and
Termination of the Agreement."

EXCHANGE OF STOCK CERTIFICATES

    Promptly after the Effective Time, CBC will cause SunTrust Bank, Atlanta,
acting in its capacity as exchange agent for CBC (the "Exchange Agent"), to mail
to the former shareholders of FSB a letter of transmittal, together with
instructions for the exchange of such shareholders' certificates representing
shares of FSB Common Stock for certificates representing shares of CBC Common
Stock.  Former shareholders of FSB will not be entitled to receive dividends on
their shares of CBC Common Stock until CBC has received their FSB stock
certificates.  FSB SHAREHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES
UNTIL THEY RECEIVE THE FORM LETTER OF TRANSMITTAL AND INSTRUCTIONS.  See "The
Merger - Distribution of Stock Certificates After the Merger."

REGULATORY APPROVALS AND OTHER CONDITIONS

    The Merger is subject to approval by the Federal Reserve and the Georgia
Department. Applications for the requisite approvals have been filed with these
agencies, each of which has yet to issue its approval of the Merger. While the
parties do not foresee any difficulty in securing such approvals, there can be
no assurance that the approvals of these agencies will be given or as to the
timing or conditions of such approvals.

    Consummation of the Merger is subject to various other conditions, including
receipt of the required approval of the Agreement by the FSB shareholders,
receipt of an opinion of counsel to CBC as to the tax-free nature of certain
aspects of the Merger, receipt of a letter regarding accounting treatment of the
Merger from the independent public accountants of CBC, and certain other
customary conditions.  See "The Merger -  Conditions to Consummation of the
Merger."


                                       6
<PAGE>
 
WAIVER, AMENDMENT, AND TERMINATION OF THE AGREEMENT

     The Agreement provides that it may be amended by a subsequent writing
signed by each party upon the approval of each of their respective Board of
Directors. However, no amendment that reduces or modifies in any material
respect the consideration to be received by the holders of FSB Common Stock in
connection with the Merger may be made after the FSB Meeting without the further
approval of such shareholders. The Agreement provides that each party may waive
any of the conditions precedent to its obligations to consummate the Merger, to
the extent legally permitted.

    The Agreement may be terminated by mutual agreement of the CBC Board of
Directors and the FSB Board of Directors. The Agreement may also be terminated
by either the CBC Board of Directors or the FSB Board of Directors (a) in the
event of breach of the Agreement by the other party that cannot or has not been
cured within 30 days of notice of such breach, (b) if the required approval of
the FSB shareholders or any applicable regulatory authority is not obtained, (c)
if the Merger is not consummated by March 31, 1998, or (d) if any of the
conditions precedent to the obligations of such party to consummate the Merger
cannot be satisfied or fulfilled by March 31, 1998. In addition, the Agreement
may be terminated, and the Merger abandoned, at any time prior to the Effective
Time by mutual action of the Boards of Directors of both CBC and FSB, or by
action of the Board of Directors of either company under certain circumstances,
including if the Merger is not consummated by March 31, 1998 unless the failure
to consummate by such time is due to a breach of the Agreement by the party
seeking to terminate.  If for any reason the Merger is not consummated, FSB will
continue to operate as a bank holding company under its present management.

    See "The Merger -  Waiver, Amendment, and Termination of the Agreement."

MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER

     After the merger, the CBC Board of Directors will consist of three current
CBC directors (Herman J. Russell, Johnnie L. Clark and Thomas E. Boland) and
three current FSB directors (Gregory T. Baranco, James E. Young and Bernard H.
Bronner). Mr. Russell will serve as the chairman of the CBC Board of Directors
and Mr. Baranco will serve as vice chairman of the board. The current president
and chief executive officer of FSB, James E. Young, will become president and
chief executive officer of CBC after the merger and shall have the authority to
select his management team. CBC will continue to serve all of the communities
currently served by both FSB and CBC.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     FSB employees, certain members of management and directors of FSB have
certain interests in, and may derive certain benefits as a result of, the Merger
that are in addition to their interests, if any, as shareholders of FSB
generally.

    The Agreement provides that  CBC will indemnify the present and former
directors, officers, employees and agents of FSB and the subsidiaries of FSB
against all liabilities arising out of actions or omissions at or prior to the
Effective Time to the full extent permitted under Georgia law and by FSB's
Articles of Incorporation or Bylaws, as currently in effect, including
provisions relating to advancement of expenses incurred in the defense of any
litigation.  In any case in which approval by CBC is required to effect any
indemnification, at the election of the indemnified party, the determination of
any such approval will be made by independent counsel mutually agreed upon
between CBC and the indemnified party.

    The Agreement also provides that CBC will honor all employment, severance,
consulting and other compensation contracts previously disclosed to CBC between
FSB or its subsidiaries and any current or former director, officer or employee,
and all provisions for vested amounts earned or accrued through the Effective
Time under FSB's benefit plans.

    The Agreement further provides that all rights with respect to FSB Common
Stock pursuant to stock options granted by FSB under its stock option plans or
agreements that are outstanding at the 


                                       7
<PAGE>
 
Effective Time, whether or not then exercisable, will be converted into and will
become rights with respect to CBC Common Stock, and CBC will assume each of such
options in accordance with its terms. All such options will become exercisable
upon consummation of the proposed Merger. FSB's President and Chief Executive
Officer holds options to purchase an aggregate of 4,000 shares of FSB Common
Stock and, pursuant to his employment agreement, an additional option to
purchase 1,000 shares of FSB Common Stock will be granted and will become
exercisable upon consummation of the proposed Merger. The number of shares of
CBC stock subject to such FSB Option will equal the number of shares of FSB
Common Stock subject to the FSB Option immediately prior to the Effective Time
(i.e., 5,000 shares) multiplied by the Exchange Ratio. The per share exercise
price under each such FSB Option shall be adjusted by dividing the per share
exercise price (i.e., $10.00) under each FSB Option by the Exchange Ratio and
rounding down to the nearest cent, resulting in a new exercise price of $6.63.
Assuming all such options were exercised as of the Effective Time, and assuming
that the market price of the CBC Common Stock that would be issued upon exercise
of such options as a result of the Merger were $9.88 per share (the per share
value ascribed to CBC Common Stock in determining the Exchange Ratio) (see "--
Fairness Opinion"), the profit realized by the President and Chief Executive
Officer would be $3.25 per share ($9.88 less $6.63) or a total of approximately
$24,505.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The Merger is intended to qualify as a reorganization under Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code"). Smith, Gambrell &
Russell, LLP, as counsel to CBC, has delivered an opinion, based upon certain
customary assumptions and representations, to the effect that,  for federal
income tax purposes, no gain or loss will be recognized by FSB shareholders as a
result of the Merger to the extent that they receive CBC Common Stock solely in
exchange for their FSB Common Stock. For a more complete description of the
federal income tax consequences of the Merger, see "The Merger -- Certain
Federal Income Tax Consequences of the Merger."

    DUE TO THE INDIVIDUAL NATURE OF THE INCOME TAX CONSEQUENCES OF THE MERGER,
SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE
SPECIFIC EFFECT OF THE MERGER ON THEM UNDER FEDERAL, STATE, LOCAL, AND FOREIGN
TAX LAWS.

ACCOUNTING TREATMENT

    It is a condition of the Agreement that the Merger will be accounted for as
a pooling-of-interests.  Under the pooling-of-interests method of accounting,
the recorded amounts of the assets and liabilities of FSB will be carried
forward and recorded on the financial statements of CBC at their previously
recorded amounts.


                                       8
<PAGE>
 
    The Agreement provides that FSB and CBC will receive a letter from Porter
Keadle Moore, LLP, dated as of the Effective Time, stating that the Merger will
qualify for pooling-of-interests accounting treatment under Accounting
Principles Board Opinion No. 16.  If the Merger does not qualify for pooling-of-
interests accounting treatment, it is expected to be abandoned. Neither CBC's
management nor FSB's management currently has any reason to believe that the
Merger will not qualify for pooling-of-interests accounting treatment.

CERTAIN DIFFERENCES IN SHAREHOLDERS' RIGHTS

    At the Effective Time, FSB shareholders, whose rights are governed by FSB's
Articles of Incorporation and Bylaws, will automatically become CBC
shareholders, and their rights as CBC shareholders will be governed by CBC's
Articles of Incorporation and Bylaws. Upon consummation of the Merger, the
rights of CBC shareholders will differ slightly from the rights of FSB
shareholders in certain respects.  See "Effect of the Merger on the Rights of
Shareholders."

RESALES BY AFFILIATES

     FSB has agreed to use its reasonable efforts to obtain from each of those
individuals identified by it as an affiliate an appropriate agreement that such
individual will not transfer any shares of CBC Common Stock received by it as a
result of the Merger, except in compliance with the applicable provisions of the
Securities Act and as required by pooling-of-interests accounting treatment. See
"The Merger -- Restrictions on Resales by Affiliates."

DISSENTERS' RIGHTS

    Holders of FSB Common Stock who dissent from the Merger are entitled to the
rights and remedies of dissenting shareholders set forth in Section 14-2-1301 et
seq. of the Georgia Business Corporation Code (the "Dissenters' Provisions"),
subject to compliance with the procedures set forth therein.  Among other
things, a dissenting shareholder is entitled to receive cash in an amount equal
to the "fair value" of such holder's shares.  A copy of the Dissenters'
Provisions of the Georgia Code is set forth in Appendix C to this Proxy
Statement/Prospectus and a summary thereof is included under "The Merger -
Dissenters' Rights."  TO PERFECT DISSENTERS' RIGHTS, A SHAREHOLDER MUST GIVE
WRITTEN NOTICE OF SUCH HOLDER'S INTENT TO DISSENT FROM APPROVAL OF THE AGREEMENT
PRIOR TO THE VOTE OF THE SHAREHOLDERS AT THE FSB SHAREHOLDERS MEETING AND SUCH
SHAREHOLDER MUST NOT VOTE HIS OR HER SHARES IN FAVOR OF THE AGREEMENT.  ANY
SHAREHOLDER WHO RETURNS A SIGNED PROXY BUT FAILS TO PROVIDE INSTRUCTIONS AS TO
THE MANNER IN WHICH SUCH HOLDER'S SHARES ARE TO BE VOTED WILL BE DEEMED TO HAVE
VOTED IN FAVOR OF THE AGREEMENT AND THUS WILL NOT BE ENTITLED TO ASSERT
DISSENTERS' RIGHTS.


COMPARATIVE MARKET PRICES OF COMMON STOCK

    There is no established public trading market for CBC Common Stock or FSB
Common Stock, nor are there uniformly quoted prices for such shares.  There are,
however, occasional transactions in CBC Common Stock and FSB Common Stock as a
result of private negotiations.


                                       9
<PAGE>
 
    Neither the management of CBC nor the management of FSB maintains a record
of the sales prices of the trades of their respective Common Stock. The last
known sale of CBC Common Stock was on July 29, 1997, one day preceding the
announcement of the Merger, at a price of $5.00 per share. The last known sale
of FSB Common Stock was on ___________, 1997, at a price of $_______ per share.

    There can be no assurance as to the market price of CBC Common Stock or
whether a public market will develop for CBC Common Stock if and when the Merger
is consummated. While CBC intends to explore listing CBC Common Stock on a
national securities exchange or qualifying CBC Common Stock for quotation on the
Nasdaq Stock Market, no assurances can be given that CBC Common Stock will ever
be listed on the Nasdaq Stock Market or any securities exchange, or that any
organized public market for CBC Common Stock will develop or that there will be
any private demand for CBC Common Stock.

COMPARATIVE PER SHARE DATA

    The following table sets forth certain comparative per share data relating
to net income, cash dividends, and book value on (a) an historical basis for CBC
and FSB, (b) a pro forma combined basis per share of CBC Common Stock, giving
effect to the Merger, and (c) an equivalent pro forma basis per share of FSB
Common Stock, giving effect to the Merger.  The CBC and FSB pro forma combined
information gives effect to the Merger on a pooling-of-interests accounting
basis and assumes an Exchange Ratio of 1.508 shares of CBC Common Stock for each
share of FSB Common Stock.  See "The Merger -  Accounting Treatment."  The
unaudited pro forma data is presented for informational purposes only and is not
necessarily indicative of the results of operations or combined financial
position that would have resulted had the Merger been consummated at the dates
or during the periods indicated, nor is it necessarily indicative of future
results of operations or combined financial position.

    The information shown below should be read in conjunction with, and is
qualified in its entirety by, the historical financial statements of CBC and
FSB, including the respective notes thereto, and the pro forma financial
information included herein and incorporated herein by reference.  See
"Documents Incorporated by Reference" and "Pro Forma Condensed Combined
Financial Information."

                                THE FSB MEETING

GENERAL

    This Proxy Statement/Prospectus is being furnished to the holders of FSB
Common Stock in connection with the solicitation by the FSB Board of Directors
of proxies for use at the FSB Meeting, at which such FSB shareholders will be
asked to vote upon a proposal to approve the Agreement.  The FSB Meeting will be
held at 4:00 p.m., local time, on ___________, 1997, at Big Miller Grove Baptist
Church, 3800 Big Miller Grove Way, Lithonia, Georgia.

    FSB shareholders are requested promptly to sign, date, and return the
accompanying proxy card to FSB in the enclosed postage-paid, addressed envelope.

    Any FSB shareholder who has delivered a proxy may revoke it at any time
before it is voted by giving notice of revocation in writing or by submitting to
FSB a signed proxy card bearing a later date, provided that such notice or proxy
card is actually received by FSB before the vote of shareholders or in open
meeting prior to the taking of the shareholder vote at the FSB Meeting.  Any
notice of revocation should be sent to First Southern Bancshares, Inc., 2727
Panola Road, Lithonia, Georgia 30358, Attention:  Willard C. Lewis, Secretary. A
proxy will not be revoked by death or supervening incapacity of the stockholder
executing the proxy unless, before the vote, notice of such death or incapacity
is filed with the Secretary.

    The shares represented by properly executed proxies received at or prior to
the FSB Meeting and not subsequently revoked will be voted as directed in such
proxies.  IF INSTRUCTIONS ARE NOT GIVEN, SHARES REPRESENTED BY PROXIES RECEIVED
WILL BE VOTED FOR APPROVAL OF THE AGREEMENT AND IN THE DISCRETION OF THE PROXY
HOLDER AS TO ANY OTHER MATTERS THAT PROPERLY MAY COME BEFORE THE FSB MEETING.
IF NECESSARY, AND UNLESS CONTRARY INSTRUCTIONS ARE GIVEN, THE PROXY HOLDER ALSO
MAY VOTE IN FAVOR OF A PROPOSAL TO ADJOURN THE SPECIAL MEETING TO PERMIT FURTHER
SOLICITATION OF PROXIES IN ORDER TO OBTAIN SUFFICIENT VOTES TO APPROVE THE
AGREEMENT.  PROXIES MARKED TO BE VOTED AGAINST THE MERGER WILL NOT BE VOTED IN
FAVOR OF SUCH A PROPOSAL TO ADJOURN.  As of the date of this Proxy
Statement/Prospectus, FSB is unaware of any other matter to be presented at the
FSB Meeting.

    The cost of soliciting proxies will be borne by FSB.  Solicitation of
proxies will be made by mail but also may be made by telephone or telegram or in
person by the directors, officers, and employees of FSB, who will receive no
additional compensation for such solicitation but may be reimbursed for out-of-
pocket expenses.  Brokerage houses, nominees, fiduciaries, and other custodians
will be requested to forward solicitation materials to beneficial owners and
will be reimbursed for their reasonable out-of-pocket expenses.

    FSB SHAREHOLDERS SHOULD NOT FORWARD ANY FSB COMMON STOCK CERTIFICATES WITH
THEIR PROXY CARDS.  IF THE MERGER IS CONSUMMATED, STOCK CERTIFICATES SHOULD BE
DELIVERED IN ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A LETTER OF TRANSMITTAL
WHICH WILL BE SENT TO FSB SHAREHOLDERS BY CBC PROMPTLY AFTER CONSUMMATION OF THE
MERGER.

RECORD DATE; VOTE REQUIRED

     FSB's Board of Directors has established the close of business on
_____________, 1997, as the record date (the "Record Date") for determining the
shareholders entitled to notice of and to vote at the FSB Meeting.  Only record
holders of FSB Common Stock as of the Record Date will be entitled to vote at
the FSB Meeting.  Approval of the Agreement requires the affirmative vote of a
majority of the shares of FSB Common Stock entitled to vote at the FSB Meeting.
Approval of any other matter presented requires the affirmative vote of a
majority of the shares present in person or by proxy and entitled to vote.  An
abstention or failure to return a properly executed proxy card will have the
same effect as a vote against the Agreement, but will not affect the outcome of
any other matter presented.  Abstentions and broker non-votes will be included
in the calculation of the number of shares represented at the FSB Meeting for
purposes of determining whether a quorum has been achieved. A broker non-vote
generally occurs when a broker who holds shares in street name for a customer
does not have the authority to vote on certain non-routine matters because the
customer has not provided any voting instructions with respect to the matter.

     BECAUSE APPROVAL OF THE AGREEMENT REQUIRES THE AFFIRMATIVE VOTE OF A
MAJORITY OF ALL THE VOTES ENTITLED TO BE CAST AT THE FSB MEETING, ABSTENTIONS
AND BROKER NON-VOTES WILL HAVE THE SAME EFFECT AS VOTES AGAINST THE AGREEMENT.
ACCORDINGLY, THE BOARD OF DIRECTORS OF FSB URGES ITS SHAREHOLDERS TO COMPLETE,
DATE, AND SIGN THE ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY IN THE
ENCLOSED, POSTAGE-PAID ENVELOPE.

    The presence, in person or by proxy, of a majority of the outstanding shares
of FSB Common Stock is necessary to constitute a quorum of the shareholders in
order to take action at the FSB Meeting.  For these purposes, shares of FSB
Common Stock that are present, or represented by proxy, at the FSB Meeting will
be counted for quorum purposes regardless of whether the holder of the shares or
proxy fails to vote on the Agreement.

    As of the Record Date, there were approximately __________ holders of
553,603 shares of FSB Common Stock outstanding and entitled to vote at the FSB
Meeting, with each share entitled to one vote.  As of such date, the directors
and executive officers of FSB and their affiliates beneficially owned 111,757
shares (or approximately 21.12% of the outstanding shares) of FSB Common Stock.
Each member of the Board of Directors of FSB has agreed to vote those shares of
FSB Common Stock beneficially owned by such member in favor of the Merger.


                                   THE MERGER

    The following material describes certain terms and aspects of the Agreement
and the Merger.  This description does not purport to be complete and is
qualified in its entirety by reference to the Appendices hereto, including the
Agreement, which is attached as Appendix A to this Proxy Statement/Prospectus
and incorporated herein by reference.  All shareholders are urged to read the
Appendices in their entirety.


                                      13
<PAGE>
 
GENERAL

    The Agreement provides for the Merger of FSB and CBC.  At the effective time
(the "Effective Time"), each share of FSB Common Stock issued and outstanding
will be converted into 1.508 shares of CBC Common Stock (the "Exchange Ratio"),
subject to adjustment in the event of a stock dividend, stock split or similar
stock reclassification.  Each share of CBC Common Stock outstanding immediately
prior to the Effective Time will remain outstanding and unchanged as a result of
the Merger.

    No fractional shares of CBC Common Stock will be issued.  Rather, cash
(without interest) will be paid in lieu of any fractional share interest to
which any FSB shareholder would be entitled upon consummation of the Merger, in
an amount equal to such fractional share of CBC Common Stock multiplied by the
"Market Value" of one share of CBC Common Stock at the Effective Time.  The
"Market Value" of one share of CBC Common Stock at the Effective Time shall be
established by the Board of Directors of CBC at the Effective Time of the
Merger.

EFFECT OF MERGER ON STOCK RIGHTS

    The Agreement provides that, at the Effective Time, all rights with respect
to FSB Common Stock pursuant to stock options ("FSB Options") granted by FSB
under the existing stock option agreements (the "FSB Stock Plans") which are
outstanding at the Effective Time, whether or not exercisable, shall be
converted into and become rights with respect to CBC Common Stock.  CBC will
assume each FSB Option, in accordance with the terms of the FSB Stock Plan by
which it is evidenced.  From and after the Effective Time, (a) each FSB Option
assumed by CBC may be exercised solely for shares of CBC Common Stock, (b) the
number of shares of CBC Common Stock subject to such FSB Option will be equal to
the number of shares of FSB Common Stock subject to such FSB Option immediately
prior to the Effective Time multiplied by the Exchange Ratio, and (c) the per
share exercise price under each such FSB Option shall be adjusted by dividing
the per share exercise price under each FSB Option by the Exchange Ratio and
rounding down to the nearest cent.  CBC will not issue any fraction of a share
of CBC Common Stock upon exercise of a FSB Option, and any fraction of a share
of CBC Common Stock that would otherwise be subject to a converted FSB Option
will represent the right to receive a cash payment equal to the product of such
fraction and the difference between the "Market Value" of one share of CBC
Common Stock and the per share exercise price of such Option.  The "Market
Value" of one share of CBC Common Stock shall be the last sales price of such
common stock on the Nasdaq Stock Market, or such other exchange or market system
on which CBC Common Stock is then traded (as reported by The Wall Street
Journal, or if not reported thereby, any other authoritative source selected by
CBC) on the last trading day preceding the date of exercise or, if the CBC
Common Stock is not then traded on Nasdaq or an exchange, the "Market Value" of
one share of CBC Common Stock shall be established by the Board of Directors of
CBC.

BACKGROUND OF AND REASONS FOR THE MERGER

    BACKGROUND OF THE MERGER.  In July, 1997, representatives of CBC contacted
FSB regarding a possible merger transaction.  The principals of the parties were
relatively familiar with each other, and the informal discussions which occurred
following that contact developed fairly rapidly.  Over the next several weeks,
the parties (a) performed detailed due diligence investigations of each other
and (b) established a joint merger committee, consisting of four directors from
each institution, to 


                                      14
<PAGE>
 
negotiate the terms of the Merger and to make recommendations to the parties'
respective Boards of Directors regarding the Merger. Thereafter, at a meeting
held on September 29, 1997, the FSB Board of Directors unanimously approved the
Agreement and the Merger provided for therein. See "-- Fairness Opinion."

    RECOMMENDATION OF THE FSB BOARD OF DIRECTORS AND REASONS FOR THE MERGER.
The FSB Board of Directors has approved the Agreement and has determined that
the Merger is fair to, and in the best interests of, FSB and its shareholders.
THE FSB BOARD OF DIRECTORS RECOMMENDS THAT HOLDERS OF FSB COMMON STOCK VOTE TO
APPROVE AND ADOPT THE AGREEMENT AND THE MERGER PROVIDED FOR THEREIN.  The FSB
Board of Directors believes that the Merger will enable holders of FSB Common
Stock to realize increased value over time as part of the combination with CBC.
The  FSB Board of Directors believes the combined company will have a greater
earnings and expansion potential than either CBC or FSB would have individually.
In that regard, the FSB Board of Directors believes that the Merger may enable
FSB shareholders to participate in opportunities for appreciation of CBC Common
Stock as a result of being part of a larger banking franchise. In reaching its
decision to approve the Agreement, the FSB Board of Directors consulted with its
outside counsel regarding the legal terms of the Merger and its fiduciary
obligations in considering of the proposed Merger, as well as with management of
FSB and, without assigning any relative or specific weight, considered the
following, which are all of the material factors considered, both from a short-
term and long-term perspective:

   (a)    The proposed composition of the CBC Board of Directors following
          consummation of the Merger which will include three former FSB
          directors and the designation of James E. Young as President and Chief
          Executive Officer of CBC following consummation of the Merger with Mr.
          Young having the authority to select his management team;

   (b)    The value of the consideration to be received by FSB shareholders
          relative to the book value and earnings per share of FSB Common Stock;

   (c)    The advice rendered by T. Stephens Johnson & Associates, Inc. as to
          the fairness, from a financial point of view, of the Exchange Ratio to
          the holders of FSB Common Stock;

   (d)    Certain information concerning the financial condition, results of
          operations and business prospects of CBC on an historical, prospective
          and pro forma basis;

   (e)    The results of FSB's due diligence review of CBC and a variety of
          factors affecting and relating to the overall strategic focus of FSB,
          including FSB's desire to expand into markets which complement its
          core markets;

   (f)    The likelihood of the Merger being approved by applicable regulatory
          authorities without undue conditions or delay;

   (g)    The compatibility of the community bank orientation of CBC to that of
          FSB;

   (h)    The enhanced marketability and liquidity of FSB Common Stock following
          the Merger;


                                      15
<PAGE>
 
   (i)    The competitive and regulatory environment for financial institutions
          generally; and

   (j)    The fact that the Merger will enable FSB shareholders to exchange
          their shares of FSB Common Stock, in a tax-free transaction, for
          shares of CBC Common Stock, the stock of which will become more widely
          held and, as a result, possibly more actively traded.

    On the basis of these considerations, the Agreement was unanimously
approved, and the FSB Board of Directors unanimously recommends that the
shareholders vote for the approval of the Agreement and the Merger provided for
therein.

    Each member of the FSB Board of Directors has agreed to vote such member's
shares of FSB Common Stock in favor of the Agreement.

    FSB'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT FSB SHAREHOLDERS VOTE
FOR APPROVAL OF THE AGREEMENT.

FAIRNESS OPINION

     T. Stephen Johnson & Associates, Inc. ("TSJ&A") is an investment banking
and financial services firm located in Atlanta, Georgia.  As part of its
investment banking business, TSJ&A engages in the review of the fairness of bank
merger 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 TSJ&A nor any of its affiliates
has a material financial interest in FSB or CBC.  TSJ&A was selected to advise
FSB's Board of Directors based upon its familiarity with FSB, the regional
community banking industry and its knowledge of the banking industry as a whole.

     TSJ&A was engaged to assist a joint merger committee of the two
institutions in arriving at an exchange ratio based on a merger of equals.
TSJ&A presented its analysis and preliminary exchange ratio to the committee on
July 27, 1997 and the committee adopted that exchange ratio as the Exchange
Ratio for the merger.  Due diligence examinations performed on behalf of the
banks concluded that no material changes were required.  TSJ&A based its opinion
on the Exchange Ratio and the analyses performed by TSJ&A in arriving at the
Exchange Ratio.

     TSJ&A has rendered its opinion (the "Fairness Opinion") to the FSB Board of
Directors that the consideration to be paid the holders of FSB Common Stock
under the Agreement is fair to such shareholders from a financial point of view.
A copy of the Fairness Opinion is attached as Appendix B to this Proxy
Statement/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 arriving at its Fairness Opinion, TSJ&A  reviewed analyses performed in
arriving at the Exchange Ratio as well the due diligence reports and publicly
available business and financial information relating to FSB and CBC.  TSJ&A
also considered certain financial and stock market data of FSB and CBC, and
compared that data with similar data for certain other publicly held 


                                      16
<PAGE>
 
banks and bank holding companies in the Southeastern United States. TSJ&A 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, TSJ&A 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 FSB and CBC
management and submitted to TSJ&A were based on assumptions believed by TSJ&A to
be reasonable and to reflect currently available information, but TSJ&A did not
independently verify such information. TSJ&A did not make an independent
evaluation or appraisal of the assets of FSB or CBC.

     In connection with rendering the Fairness Opinion and Exchange Ratio, TSJ&A
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 TSJ&A in this regard. The preparation of a fairness
opinion/exchange ratio 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, TSJ&A 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, TSJ&A made numerous assumptions with respect to
industry performance, business and economic conditions and other matters, many
of which are beyond FSB's or CBC's control.  The analyses performed by TSJ&A are
not necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses. 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.

     TSJ&A performed three separate analyses, weighted the results, and arrived
at an analysis valuation summary which was used to determine the Exchange Ratio.
The goal of the merger committee was to create a merger of equals.  Therefore,
TSJ&A placed more weight on the analyses that considered the companies as a
going concern, with less weight given to the acquisition value of the companies,
which considers consolidation savings and recent peer group acquisitions.  The
following is a description of the three analyses used in arriving at the
Exchange Ratio and the basis for rendering the Fairness Opinion.

     ADJUSTED BOOK VALUE.  This analysis attempts to adjust the equity of each
institution taking into account the market value of assets, deduction for
intangibles and exercise of outstanding options. The Adjusted Book Value was
weighted 45 percent.

     The adjusted book values per share for FSB and CBC at June 30, 1997 were
$10.94 and $7.45 respectively.  Due diligence examinations did not warrant any
change to these figures.

     INVESTMENT VALUE. This analysis attempts to calculate the purchase price
one would pay for a non-control position given a required rate of return and an
investment period of five years.  Performance projections for the five-year
period are based on current market growth rates and historical performance of
the two institutions.  The Investment Value was weighted 45 percent.


                                      17
<PAGE>
 
     TSJ&A assumed a range of required rates of return from 8 percent to 12
percent, with an average per share Investment Value for FSB and CBC of $13.50
and $6.47, respectively.  Again, due diligence examinations did not warrant any
change to these figures.

     ACQUISITION VALUE.  This analysis attempts to determine what a larger bank
holding company would pay for a control position based on 1997 projected
earnings and given no dilution to the holding company shareholders.  Calculated
efficiencies and consolidation savings are included in the analysis.  This
analysis does not project an actual acquisition based on future earnings growth.
The Acquisition Value was weighted 10 percent.

     Both FSB and CBC are located in the Atlanta metropolitan area.  It was
assumed that should either institution be acquired by a large bank holding
company, substantial consolidation savings could be realized.  The acquisition
value for FSB and CBC considered acquisitions by Colonial BancGroup, Montgomery,
Alabama (CNB); First Union Corporation, Charlotte, North Carolina (FTU);
NationsBank, Charlotte, North Carolina (NB); Regions Financial Corporation,
Montgomery, Alabama (RGBK); SouthTrust Corporation, Birmingham, Alabama (SOTR);
SunTrust Bank, Inc., Atlanta, Georgia (STI); Wachovia Corporation, Winston-
Salem, North Carolina (WB); AmSouth Bancorporation, Birmingham, Alabama (ASO);
each assuming 40 percent consolidation savings.  The Acquisition Values
calculated for FSB and CBC were $39.05 per share and $36.19 per share,
respectively.

     The valuation summary of the weighted analyses for FSB and CBC resulted in
a value of $14.90 and $9.88 per share, respectively. It was determined that CBC
will be the resulting institution and that FSB will merge into CBC.  The
Exchange Ratio was determined by dividing the per share value of FSB by the per
share value of CBC.

     Based upon its original Exchange Ratio calculation and assuming the
accuracy and completeness of all the information, reports and data provided,
TSJ&A has been able to conclude that the consideration to be paid to the holders
of FSB common stock under the Merger Agreement is fair to such shareholders from
a financial point of view.

     TSJ&A's services as an independent financial analyst, working with both
institutions to develop the Exchange Ratio as part of a merger of equals and
providing a Fairness Opinion to the FSB Board of Directors, have been performed
for a fee of $20,000 plus reimbursement of out-of-pocket expenses.  This fee is
not contingent upon consummation of the transaction.

EFFECTIVE TIME OF THE MERGER

     Subject to the conditions to the obligations of the parties to effect the
Merger, the Merger will become effective upon the filing of Articles of Merger
filed by CBC with the Georgia Secretary of State. Unless otherwise agreed upon
by CBC and FSB, and subject to the conditions to the obligations of the parties
to effect the Merger, the parties will use their reasonable efforts to cause the
Effective Time to occur by the fifth business day after the last of the
following events occurs:  (a) the effective date (including the expiration of
any applicable waiting period) of the last federal or state regulatory approval
required for the Merger; or (b)  the date on which the Agreement is approved by
the requisite vote of FSB shareholders.


                                      18
<PAGE>
 
     No assurance can be provided that the necessary shareholder and regulatory
approvals can be obtained or that other conditions precedent to the Merger can
or will be satisfied.  CBC and FSB anticipate that all conditions to
consummation of the Merger will be satisfied so that the Merger can be
consummated during the last quarter of 1997 or the first quarter of 1998.
However, delays in the consummation of the Merger could occur.

     The Board of Directors of either CBC or FSB generally may terminate the
Agreement if the Merger is not consummated by March 31, 1998, unless the failure
to consummate by that date is the result of a breach of the Agreement by the
party seeking termination.  See "--  Conditions to Consummation of the Merger"
and "-- Waiver, Amendment, and Termination of the Agreement."

DISTRIBUTION OF STOCK CERTIFICATES AFTER THE MERGER

     Promptly after the Effective Time, CBC will cause Sun Trust Bank, Atlanta
(the "Exchange Agent") to mail to the former shareholders of FSB a letter of
transmittal, together with instructions for the exchange of such shareholders'
certificates representing shares of FSB Common Stock for certificates
representing shares of CBC Common Stock.

     FSB SHAREHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL THEY
RECEIVE THE FORM LETTER OF TRANSMITTAL AND INSTRUCTIONS.  Upon surrender to the
Exchange Agent of certificates for FSB Common Stock together with a properly
completed letter of transmittal, there will be issued and mailed to each holder
of FSB Common Stock surrendering such items a certificate or certificates
representing the number of shares of CBC Common Stock to which such holder is
entitled as a result of the Merger.  After the Effective Time, to the extent
permitted by law, holders of record of FSB Common Stock as of the Effective Time
will be entitled to vote at any meeting of CBC shareholders the number of shares
of CBC Common Stock into which their FSB Common Stock has been converted,
regardless of whether such shareholders have surrendered their FSB stock
certificates.  NO DIVIDEND OR OTHER DISTRIBUTION PAYABLE AFTER THE EFFECTIVE
TIME WITH RESPECT TO CBC COMMON STOCK, HOWEVER, WILL BE PAID TO THE HOLDER OF
ANY UNSURRENDERED FSB STOCK CERTIFICATE UNTIL THE HOLDER DULY SURRENDERS SUCH
CERTIFICATE.  Upon such surrender, all undelivered dividends and other
distributions will be delivered to such shareholder, in each case without
interest.

     After the Effective Time, there will be no transfers of shares of FSB
Common Stock on FSB's stock transfer books.  If certificates representing shares
of FSB Common Stock are presented for transfer after the Effective Time, they
will be canceled and exchanged for the shares of CBC Common Stock deliverable in
respect thereof.

CONDITIONS TO CONSUMMATION OF THE MERGER

     Consummation of the Merger is subject to a number of conditions, including,
but not limited to:

     (a) approval from the Federal Reserve and the Georgia Department without
any conditions or restrictions that would, in the reasonable judgment of either
party, so materially adversely impact the economic benefits of the transactions
contemplated by the Agreement as to render inadvisable the consummation of the
Merger, and the expiration of applicable waiting periods under the BHC Act;


                                      19
<PAGE>
 
     (b) Approval by the holders of a majority of the shares of FSB Common Stock
entitled to vote on the Agreement;

     (c) The absence of any action by any court or governmental authority
restraining or prohibiting the Merger;

     (d) The receipt of an opinion of counsel to the effect that, among other
things:  (i) the Merger will constitute a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code");
(ii) the exchange in the Merger of FSB Common Stock for CBC Common Stock will
not give rise to gain or loss to FSB shareholders, except to the extent of any
cash received; and (iii) neither CBC nor FSB will recognize gain or loss as a
consequence of the Merger, except for deferred gain or loss recognized pursuant
to Treasury Regulations issued under Section 1502 of the Code;

     (e) Receipt of a letter from Porter Keadle Moore, LLP, dated as of the
Effective Time, confirming that the Merger will qualify for pooling-of-interests
accounting treatment.

     Consummation of the Merger also is subject to the satisfaction or waiver of
various other conditions specified in the Agreement, including, among others:
(a) the delivery by CBC and FSB of certificates executed by their respective
Chief Executive Officers and Chief Financial Officers as to compliance with the
Agreement; and (b) as of the Effective Time, the accuracy of certain
representations and warranties and the compliance in all material respects with
the agreements and covenants of each party.

     No assurance can be provided as to when or if all of the conditions
precedent to the Merger can or will be satisfied or waived by the party
permitted to do so.  In the event the Merger is not effected on or before March
31, 1998, the Agreement may be terminated and the Merger abandoned by a vote of
a majority of the Board of Directors of either CBC or FSB.  See " - Waiver,
Amendment, and Termination of the Agreement."

REGULATORY APPROVALS

     The Merger may not proceed in the absence of receipt of the requisite
regulatory approvals.  There can be no assurance that such regulatory approvals
will be obtained or as to the timing of such approvals.  There also can be no
assurance that such approvals will not be accompanied by a conditional
requirement which causes such approvals to fail to satisfy the conditions set
forth in the Agreement.  Applications for the approvals described below have
been submitted to the appropriate regulatory agencies.

     CBC and FSB are not aware of any material governmental approvals or actions
that are required for consummation of the Merger, except as described below.
Should any other approval or action be required, it presently is contemplated
that such approval or action would be sought.

     The Merger requires the prior approval of the Federal Reserve.  In granting
its approval, the Federal Reserve must take into consideration, among other
factors, the financial and managerial resources and future prospects of the
institutions and whether the Merger can reasonably be expected to produce
benefits to the public, such as greater convenience, increased competition, or
gains in efficiency, that outweigh possible adverse effects, such as undue
concentration of resources, 


                                      20
<PAGE>
 
decreased or unfair competition, conflicts of interest, or unsound banking
practices. Under the BHC Act, the Merger may not be consummated until the 30th
day following the date of Federal Reserve approval, which may be shortened by
the Federal Reserve to the 15th day, during which time the United States
Department of Justice may challenge the transaction on antitrust grounds. The
commencement of any antitrust action would stay the effectiveness of the Federal
Reserve's approval, unless a court specifically orders otherwise.

     The Merger also is subject to the approval of the Georgia Department.  In
its evaluation, the Georgia Department will take into account considerations
similar to those applied by the Federal Reserve.

WAIVER, AMENDMENT, AND TERMINATION OF THE AGREEMENT

     Prior to the Effective Time, and to the extent permitted by law, any
provision of the Agreement generally may be (a) waived by the party benefited by
the provision or (b) amended by a written agreement between CBC and FSB approved
by their respective Boards of Directors; provided, however, that after approval
by the FSB shareholders, no amendment that would require further approval by
such shareholders under the Georgia Business Corporation Code ("Georgia Code")
may be made without the approval of such shareholders.

     The Agreement may be terminated, and the Merger abandoned, at any time
prior to the Effective Time, either before or after approval by the FSB
shareholders, under certain circumstances, including:

     (a) By mutual agreement of the Boards of Directors of CBC and FSB;

     (b) By the Board of Directors of either party, in the event of the other
party's breach or failure to comply with any provision of the Agreement which
meets certain standards specified in the Agreement;

     (c) By the Board of Directors of either party, upon final nonappealable
denial of any required regulatory approval;

     (d) By the Board of Directors of either party, if the shareholders of FSB
have not approved the Agreement in accordance with the provisions of the Georgia
Code;

     (e) By the Board of Directors of either party, if the Merger shall not have
been consummated by March 31, 1998, but only if the failure to consummate the
Merger by such date has not been caused by the terminating party's breach of the
Agreement; or

     (f) By the Board of Directors of either party, in connection with entering
into a competing definitive agreement in accordance with the terms of the
Agreement.

     If the Agreement is terminated as described above, the Agreement will
become void and have no effect, except that certain provisions of the Agreement,
including those related to the obligations to share expenses, maintain
confidentiality of certain information and return all documents obtained from
the other party under the Agreement will survive.  See "--Expenses and Fees" for
additional information concerning the payment of expenses.

CONDUCT OF BUSINESS PENDING THE MERGER

     Each of CBC and FSB generally has agreed, unless the prior consent of the
other party is obtained, and except as otherwise contemplated by the Agreement,
to operate its business only in the ordinary course, preserve intact its
business organization and assets, maintain its rights and franchises, and take
no action that would affect, adversely and materially, the ability of either
party to perform its covenants and agreements under the Agreement or that would
adversely affect either party's ability to obtain any consent or approval
required for the consummation of the transactions contemplated by the Agreement.
In addition, the Agreement contains certain other restrictions applicable to the
conduct of the business of both CBC and FSB prior to consummation of the Merger,
as described below.

     Each party has agreed not to take certain actions relating to the operation
of its business pending consummation of the Merger without the prior approval of
the other party.  Those actions generally include, without limitation:  (a)
amending its Articles of Incorporation or Bylaws; (b) becoming responsible for
any obligation for borrowed money in excess of certain limits; (c) acquiring or
exchanging any shares of its capital stock or paying any dividend or other
distribution in respect of its capital stock, except that FSB is permitted to
declare and pay its regular annual cash dividend of up to $.05 per share on the
FSB Common Stock and CBC is permitted to declare and pay its regular annual cash
dividend of up to $.10 per share on the CBC Common Stock; (d) issuing or selling
any additional shares of its capital stock, any rights to acquire any such
stock, or any security convertible into such stock (except as set forth in the
Agreement, as previously disclosed to the other party, or pursuant to the
exercise of outstanding stock options); (e) adjusting or reclassifying any of
its capital stock, disposing of or encumbering any shares of capital stock of
any subsidiary (excluding inter-company transfers) or disposing of or
encumbering any asset with a book value in excess of certain limits other than
in the ordinary course of business; (f) purchase any securities or make any
material investment in any person, other than a wholly-owned subsidiary, other
than in connection with foreclosures in the ordinary course of business or
acquisition of control by a depository institution subsidiary in its fiduciary
capacity; (g) granting any increase in compensation or benefits to employees or
officers (except in accordance with past practice or prior obligation, in each
case as previously disclosed to the other party or as required by law), paying
any bonus (except as previously disclosed or in accordance with any existing
program or plan), entering into or amending any severance agreements with
officers, or granting any increase in compensation or other benefits to
directors of CBC or FSB or any of their subsidiaries; (h) entering into or
amending any employment contract that it does not have the unconditional right
to terminate without liability other than for services already rendered; (i)
adopting any new employee benefit plan or program, or materially changing any
existing plan or program except for any change required by law or advisable to
maintain the tax qualified status of any such plan; (j) making any significant
change in any tax or accounting methods or systems of internal accounting
controls (except in conformity to changes in tax laws, regulatory accounting
requirements or generally accepted accounting principles); (k) settling any
litigation involving liability of CBC or FSB or any of their subsidiaries for
damages in excess of certain limits or material restrictions upon its
operations; or (l) modifying or terminating any material contract except in the
ordinary course of business.

     In addition, each party has agreed not to solicit, directly or indirectly,
any acquisition proposal from any other person or entity.  Each party also has
agreed not to negotiate with respect to any such proposal, provide nonpublic
information to any party making such a proposal, or enter into 


                                      22
<PAGE>
 
any agreement with respect to any such proposal, except in compliance with the
fiduciary obligations of its Board of Directors. In addition, each party has
agreed to use its reasonable efforts to prevent its advisors and other
representatives from engaging in any of the foregoing activities.

MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER

     After the Merger, the CBC Board of Directors will consist of three current
CBC directors (Herman J. Russell, Johnnie L. Clark and Thomas E. Boland) and
three current FSB directors (Gregory T. Baranco, James E. Young and Bernard H.
Bronner).  Mr. Russell will serve as CBC's Chairman of the Board and Mr. Baranco
will serve as CBC's Vice Chairman of the Board.  The current President and Chief
Executive Officer of FSB, James E. Young, will become President and Chief
Executive Officer of CBC after the Merger and shall have the authority to select
his management team. CBC will continue to serve all of the communities currently
served by both FSB and CBC.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

    The Agreement provides that  CBC will indemnify the present and former
directors, officers, employees and agents of FSB and the subsidiaries of FSB
against all liabilities arising out of actions or omissions at or prior to the
Effective Time to the full extent permitted under Georgia law and by FSB's
Articles of Incorporation or Bylaws, as currently in effect, including
provisions relating to advancement of expenses incurred in the defense of any
litigation.  In any case in which approval by CBC is required to effect any
indemnification, at the election of the indemnified party, the determination of
any such approval will be made by independent counsel mutually agreed upon
between CBC and the indemnified party.

    The Agreement also provides that CBC will honor all employment, severance,
consulting and other compensation contracts previously disclosed to CBC between
FSB or its subsidiaries and any current or former director, officer or employee,
and all provisions for vested amounts earned or accrued through the Effective
Time under FSB's benefit plans.

     The Agreement further provides that all rights with respect to FSB Common
Stock pursuant to stock options granted by FSB under its stock option plans or
agreements that are outstanding at the Effective Time, whether or not then
exercisable, will be converted into and will become rights with respect to CBC
Common Stock, and CBC will assume each of such options in accordance with its
terms.  All such options will become exercisable upon consummation of the
proposed Merger. FSB's President and Chief Executive Officer holds options to
purchase an aggregate of 4,000 shares of FSB Common Stock and, pursuant to his
employment agreement, an additional option to purchase 1,000 shares of FSB
Common Stock will be granted and will become exercisable upon consummation of
the proposed Merger. The number of shares of CBC stock subject to such FSB
Option will equal the number of shares of FSB Common Stock subject to the FSB
Option immediately prior to the Effective Time (i.e., 5,000 shares) multiplied
by the Exchange Ratio. The per share exercise price under each such FSB Option
shall be adjusted by dividing the per share exercise price (i.e., $10.00) under
each FSB Option by the Exchange Ratio and rounding down to the nearest cent,
resulting in a new exercise price of $6.63. Assuming all such options were
exercised as of the Effective Time, and assuming that the market price of the
CBC Common Stock that would be issued upon exercise of such options as a result
of the Merger were $9.88 per share (the per share value ascribed to CBC Common
Stock in determining the Exchange Ratio) (see "- Fairness

                                      23
<PAGE>
 
Opinion"), the profit realized by the President and Chief Executive Officer
would be $3.25 per share ($9.88 less $6.63) or a total of approximately $24,505.

DISSENTERS' RIGHTS

     Pursuant to Section 14-2-1301, et seq. of the Georgia Code (the
"Dissenters' Provisions"), any holder of record of FSB Common Stock who objects
to the Merger, and who fully complies with all of the Dissenters' Provisions
(but not otherwise) shall be entitled to demand and receive payment for all (but
not less than all) of his or her shares of FSB Common Stock if the proposed
Merger is consummated.

     A shareholder of  FSB who objects to the Merger and desires to receive
payment of the "fair value" of his or her stock:

     (a)  Must file a written objection to the Merger with FSB either prior to
the meeting or at the meeting but before the vote is taken, and the written
objection must contain a statement that the shareholder intends to demand
payment for his or her shares if the Merger is approved; AND

     (b) Must either abstain from voting or vote against approval of the Merger;
AND

     (c) Must demand payment and deposit his or her certificate(s) in accordance
with the terms of the dissenters' notice sent to the dissenting shareholder
following approval of the Merger.

     A vote against the Merger alone will not constitute the separate written
notice and demand for payment referred to in (a) and (c) above; dissenting
shareholders must separately comply with all three conditions. Any notice
required to be given to FSB must be forwarded to First Southern Bancshares,
Inc., 2727 Panola Road, Lithonia, Georgia 30058, Attention: Willard C. Lewis.

     If the Merger is approved, FSB will mail no later than 10 days after the
approval by certified mail to each shareholder who has complied with conditions
(a) and (b) above, written notice of such approval, addressed to the shareholder
at such address as the shareholder has furnished to FSB in writing, or if none,
at the shareholder's address as it appears on the records of FSB. FSB will set a
date by which it must receive the payment demand, which date may not be fewer
than 30 nor more than 60 days after the date the dissenters' notice is
delivered. The shareholder must make the written election to dissent and demand
for payment described in condition (c) above by the payment demand date as set
by FSB.

     If all three of the above conditions are satisfied in full, CBC is required
to make a written offer within 10 days of receiving the payment demand, or
within 10 days after the consummation of the Merger, whichever is later, to each
dissenting shareholder to purchase all of such shareholder's shares of FSB
Common Stock at a specific price.  If CBC and any dissenting shareholder are
unable to agree on the fair value of the shares within 60 days, CBC will
commence a proceeding in the Superior Court of Fulton County to determine the
rights of the dissenting shareholder and the fair value of his or her shares.
The court may appoint appraisers to receive evidence and to recommend a decision
on fair value. If CBC does not commence the proceeding within the 60-day period,
it shall pay each dissenter whose demand remains unsettled the amount demanded.



                                      24
<PAGE>
 
     Upon compliance with the statutory procedures, dissenting shareholders will
not have any rights as shareholders of either FSB or CBC, including, among other
things, the right to receive dividends and the right to vote on matters
submitted for shareholder consideration.

     The foregoing does not purport to be a complete statement of the
Dissenters' Provisions and it is qualified in its entirety by reference to said
provisions, which are reproduced in full as Appendix C to this Proxy
Statement/Prospectus.  However, the foregoing does describe all of the material
provisions of Georgia law with which dissenting shareholders must comply in
order to preserve their dissenters' rights.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     THE FOLLOWING IS A SUMMARY OF CERTAIN ANTICIPATED FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER.  THIS SUMMARY IS BASED ON THE FEDERAL INCOME TAX
LAWS NOW IN EFFECT AND AS CURRENTLY INTERPRETED; IT DOES NOT TAKE INTO ACCOUNT
POSSIBLE CHANGES IN SUCH LAWS OR INTERPRETATIONS, INCLUDING AMENDMENTS TO
APPLICABLE STATUTES OR REGULATIONS OR CHANGES IN JUDICIAL OR ADMINISTRATIVE
RULINGS, SOME OF WHICH MAY HAVE RETROACTIVE EFFECT.  THIS SUMMARY DOES NOT
PURPORT TO ADDRESS ALL ASPECTS OF THE POSSIBLE FEDERAL INCOME TAX CONSEQUENCES
OF THE MERGER AND IS NOT INTENDED AS TAX ADVICE TO ANY PERSON.  IN PARTICULAR,
AND WITHOUT LIMITING THE FOREGOING, THIS SUMMARY DOES NOT ADDRESS THE FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER TO SHAREHOLDERS IN LIGHT OF THEIR
PARTICULAR CIRCUMSTANCES OR STATUS (FOR EXAMPLE, AS FOREIGN PERSONS, TAX-EXEMPT
ENTITIES, DEALERS IN SECURITIES, INSURANCE COMPANIES, OR CORPORATIONS, AMONG
OTHERS OR WITH RESPECT TO SHAREHOLDERS WHO ACQUIRED THEIR SHARES OF FSB COMMON
STOCK PURSUANT TO THE EXERCISE OF FSB OPTIONS OR OTHERWISE AS COMPENSATION).
NOR DOES THIS SUMMARY ADDRESS ANY CONSEQUENCES OF THE MERGER UNDER ANY STATE,
LOCAL, ESTATE, OR FOREIGN TAX LAWS.  SHAREHOLDERS, THEREFORE, ARE URGED TO
CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF
THE MERGER, INCLUDING TAX RETURN REPORTING REQUIREMENTS, THE APPLICATION AND
EFFECT OF FEDERAL, FOREIGN, STATE, LOCAL, AND OTHER TAX LAWS, AND THE
IMPLICATIONS OF ANY PROPOSED CHANGES IN THE TAX LAWS.

     A federal income tax ruling with respect to this transaction was not
requested from the Internal Revenue Service.  Instead, based on certain
customary assumptions and representations, Smith, Gambrell & Russell, LLP,
counsel to CBC, has rendered an opinion to CBC and FSB concerning certain
federal income tax consequences of the proposed Merger under federal income tax
law.  It is such firm's opinion that:

     (a) Provided the Merger qualifies as a statutory merger under the Georgia
Code, the Merger will be a reorganization within the meaning of Section 368(a)
of the Code.

     (b) The shareholders of FSB will recognize no gain or loss upon the
exchange of their FSB Common Stock solely for shares of CBC Common Stock.  Each
FSB shareholder's basis in the CBC Common Stock received in the exchange will be
equal to such shareholder's basis in the FSB Common Stock surrendered in
exchange for CBC Common Stock in the Merger (reduced by the basis allocable to
any fractional interest in any share of CBC Common Stock for which cash is
received). Each FSB shareholder's holding period for the CBC Common Stock will
include the period that such shareholder held his or her FSB Common Stock
surrendered in exchange for CBC Common Stock in the Merger, provided that the
FSB Common Stock was a capital asset in the hands of such shareholder.



                                      25
<PAGE>
 
     (c) The receipt of cash in lieu of fractional shares of CBC Common Stock
will be treated as if the fractional shares were distributed as part of the
exchange and then redeemed by CBC.  These cash payments will be treated as
having been received as distributions in full payment in exchange for the
fractional shares of CBC Common Stock redeemed as provided under Section 302(a)
of the Code. Any gain or loss recognized will be capital gain or loss, provided
the fractional share constitutes a capital asset in the hands of the exchanging
shareholder and the requirements of Section 302(b)(1) are met.  FSB shareholders
receiving cash in lieu of fractional shares should consult their own tax
advisors as to the tax treatment in their particular circumstances (i.e.,
exchange treatment or dividend).

     (d) Neither FSB nor CBC will recognize gain or loss for federal income tax
purposes as a consequence of the Merger.

ACCOUNTING TREATMENT

     It is the intention of the parties that the Merger be treated for financial
reporting purposes as a pooling-of-interests.  Under the pooling-of-interests
method of accounting, the recorded amounts of the assets and liabilities of FSB
will be carried forward and recorded on the financial statements of CBC at their
previously recorded amounts.

     The Agreement provides that CBC and FSB will receive a letter from Porter
Keadle Moore, LLP, dated as of the Effective Time, stating that the Merger will
qualify for pooling-of-interests for financial reporting purposes.  If the
Merger does not qualify for pooling-of-interests accounting treatment, it will
be abandoned.  Neither CBC's management nor FSB's management currently has any
reason to believe that the Merger will not qualify for pooling-of-interests
accounting treatment.

     For information concerning certain conditions to be imposed on the exchange
of FSB Common Stock for CBC Common Stock in the Merger by affiliates of FSB and
certain restrictions to be imposed on the transferability of the CBC Common
Stock received by those affiliates in the Merger in order, among other things,
to ensure the availability of pooling-of-interests accounting treatment, see 
"--Resales of CBC Common Stock by Affiliates."

EXPENSES AND FEES

     The Agreement provides, in general, that each of the parties will bear and
pay its own expenses in connection with the transactions contemplated by the
Agreement, including fees and expenses of its own consultants, investment
bankers, accountants, and counsel, except that FSB and CBC will each bear and
pay one-half of the filing fees and printing or copying costs associated with
the Registration Statement and this Proxy Statement/Prospectus and one-half of
the filing fees associated with any regulatory application.

     The Agreement also provides that if it is terminated by CBC because (a) FSB
has breached its representations, warranties or covenants, (b) FSB has failed to
satisfy the conditions to CBC's obligation to consummate the Merger, (c) FSB
shareholders fail to approve the Agreement, but only if FSB has received a
competing proposal, or (d) FSB has entered into a definitive agreement with a
competing party, then FSB will pay CBC $250,000 plus CBC's out-of-pocket
expenses up to but not exceeding $250,000.  Similarly, if the Agreement is
terminated by FSB as a result of the foregoing 


                                      26
<PAGE>
 
reasons, excluding failure to receive shareholder approval which is not
applicable, then CBC will pay FSB $250,000 plus FSB's out-of-pocket expenses up
to but not exceeding $250,000

RESALES OF CBC COMMON STOCK BY AFFILIATES

     The shares of CBC Common Stock to be issued to FSB shareholders in the
Merger have been registered under the Securities Act, but that registration does
not cover resales of those shares by persons who control, are controlled by, or
are under common control with, FSB (such persons are referred to hereinafter as
"affiliates" and generally include executive officers, directors and other
controlling shareholders) at the time of the FSB Meeting.  Affiliates may not
sell shares of CBC Common Stock acquired in connection with the Merger, except
pursuant to an effective registration statement under the Securities Act or in
compliance with SEC Rule 145 or another applicable exemption from the Securities
Act registration requirements and until such time as financial results covering
at least 30 days of combined operations of CBC and FSB after the consummation of
the Merger have been published.  Similarly, affiliates of CBC generally may not
sell their shares of CBC Common Stock until such time as financial results
covering at least 30 days of combined operations of CBC and FSB after
consummation of the Merger have been published.

     Each person who FSB reasonably believes to be an affiliate of FSB has
delivered to CBC a written agreement providing that such person generally will
not sell, pledge, transfer, or otherwise dispose of any CBC Common Stock to be
received by such person upon consummation of the Merger, except in compliance
with the Securities Act, the rules and regulations of the SEC promulgated
thereunder and applicable restrictions regarding pooling-of-interests accounting
treatment.  Additionally, each person who CBC reasonably believes to be an
affiliate of CBC has delivered to FSB a written agreement providing that such
person generally will not sell, pledge, transfer or otherwise dispose of any CBC
Common Stock except in compliance with the applicable restrictions regarding
pooling-of-interests accounting treatment.

    Neither the management of CBC nor the management of FSB maintains a record
of the sales prices of the trades of their respective Common Stock. The last
known sale of CBC Common Stock was on July 29, 1997, one day preceding the
announcement of the Merger, at a price of $5.00 per share. The last known sale
of FSB Common Stock was on ___________, 1997, at a price of $_______ per share.

    The holders of CBC Common Stock are entitled to receive dividends when
declared by the Board of Directors out of funds legally available therefor. CBC
has paid cash dividends since 1985. Although CBC currently intends to continue
to pay cash dividends on the CBC Common Stock, there can be no assurance that
CBC's dividend policy will remain unchanged after completion of the Merger. The
declaration and payment of dividends thereafter will depend upon business
conditions, operating results, capital and reserve requirements, and the Board
of Directors' consideration of other relevant factors. For information with
respect to provisions limiting dividends payable by CBC and FSB while the Merger
is pending see "Description of Merger - Conduct of the Business Pending the
Merger."

    CBC and FSB are legal entities separate and distinct from their respective
subsidiaries and their respective revenues depend in significant part on the
payment of dividends from their respective subsidiary depository institutions.
Such subsidiary depository institutions are subject to certain legal
restrictions on the amount of dividends they are permitted to pay

SHAREHOLDERS OF RECORD

    As of September 30, 1997, there were 894 holders of record of CBC Common
Stock and [956] holders of record of FSB Common Stock.

PRO FORMA CONDENSED COMBINED STATEMENTS OF INCOME

    The following unaudited pro forma condensed combined statements of income
have been prepared for the six-month periods ended June 30, 1997 and 1996, and
for each of the three years in the period ended December 31, 1996, and give
effect to the Merger, assuming the Merger is accounted for as a pooling-of-
interests. The unaudited pro forma condensed combined statements of income
should be read in conjunction with the historical consolidated financial
statements of CBC and FSB, including the respective notes thereto, which are
incorporated by reference in this Proxy Statement/Prospectus and the unaudited
consolidated historical and other pro forma financial information, including the
notes thereto, appearing elsewhere in this Proxy Statement/Prospectus. The pro
forma condensed combined statements of income are not necessarily indicative of
the results that actually would have occurred if the Merger had been consummated
on the dates indicated or which may be obtained in the future.

     CBC is a registered bank holding company under the BHC Act and owns 100% of
the outstanding capital stock of Citizens Trust Bank ("Citzens Trust"). CBC was
incorporated under the laws of the State of Georgia in 1972 to enhance Citizens
Trust's ability to serve its customers' requirements for financial services. The
holding company structure provides flexibility for expansion of CBC's banking
business through acquisition of other financial institutions and the provision
of additional banking-related services which the traditional commercial bank may
not provide under present laws.

     Citizens Trust was organized under the laws of the State of Georgia in 1921
and is a member of the Federal Reserve System.  Citizens Trust's main office is
located in 30,000 square feet of leased office space on the ground floor of a
12-story building located at 175 John Wesley Dobbs Avenue in downtown Atlanta,
Georgia.  Citizens Trust has eight full service branches, two of which are
located in supermarkets, located in Fulton and DeKalb Counties, Georgia.
Citizens Trust owns the land and buildings of three free-standing branches, one
near the Atlanta University Center, one in the Adamsville section of the City of
Atlanta, and one in the City of East Point.  Citizens Trust leases space for its
supermarket branches under license agreements, and leases a free-standing
facility in the Midtown section of the City of Atlanta.

     Citizens Trust operates a full service banking business providing customary
banking services such as consumer and commercial checking accounts, negotiable
order of withdrawal ("NOW") accounts, savings accounts, various types of time
deposits, safe deposit facilities, money transfers, commercial loans, real
estate loans, home equity loans and consumer/installment loans.  Citizens Trust
conducts limited trust activities, which primarily include serving as trustee
for bond issues for three colleges and for local governments.

                             INFORMATION ABOUT FSB
                                        
     FSB was incorporated as a Georgia business corporation on February 16, 1995
and became a bank holding company by acquiring all of the common stock of First
Southern Bank ("First Southern") on July 3, 1995.  FSB presently has two
operating subsidiaries, First Southern and FSB Mortgage Services, Inc.
("Mortgage Services"), a mortgage company.  FSB was organized to facilitate
First Southern's ability to serve its customers' requirements for financial
services.
 
     First Southern was incorporated on March 16, 1987, and opened for business
on April 26, 1989.  Its home office is located at 2727 Panola Road, Lithonia,
Georgia  30058.  In 1994, First Southern opened a branch office in the South
DeKalb Mall, Decatur, Georgia and in 1996 opened an additional branch in the
Rockbridge Place Shopping Center, Stone Mountain, Georgia in order to provide
more convenient services for the residents of its service area.  First Southern
conducts a general commercial banking business that serves South DeKalb County.
 
     First Southern's primary service area is South DeKalb County, along with
certain portions of Rockdale County. The primary focuses of First Southern are
the small business and commercial/service firms in the area plus individuals and
households who reside in or commute to the area.
 
     FSB acquired the assets of and employed the personnel of American Financial
Mortgage Corp. on September 9, 1996.  The resulting company, Mortgage Services,
is a mortgage company licensed by the State of Georgia and has received lender
approval from the Department of Housing and Urban Development, Farmers Home
Administration, Federal National Mortgage Association and the Veterans
Administration.

                        DESCRIPTION OF CBC COMMON STOCK

     CBC is currently authorized to issue 5,000,000 shares of CBC Common Stock,
of which 1,329,684 shares were issued and outstanding at September 30, 1997.
Holders of CBC Common Stock are entitled to receive such dividends as may be
declared by the Board of Directors out of funds legally available therefor.  The
ability of CBC to pay dividends is affected by the ability of the subsidiaries
of CBC to pay dividends, which for the bank subsidiary is limited by applicable
regulatory requirements and capital guidelines. At September 30, 1997, under
such requirements and guidelines, the subsidiary had $320,000 of undivided
profits legally available for the payment of dividends without regulatory
approval.

     For a further description of CBC Common Stock, see "Effect of the Merger on
Rights of Stockholders."


                 EFFECT OF THE MERGER ON RIGHTS OF SHAREHOLDERS

     At the Effective Time, FSB shareholders will become shareholders of CBC,
and their rights as shareholders will be determined by CBC's Articles of
Incorporation and Bylaws.  Because CBC and FSB are Georgia corporations governed
by the Georgia Code, there are no material differences between the rights of CBC
shareholders and the rights of FSB shareholders under the Georgia Code.
Accordingly, the following is a summary of the material differences in the
rights of shareholders of CBC and FSB based on a comparison of CBC's Articles of
Incorporation and Bylaws with FSB's Articles of Incorporation and Bylaws.  This
summary does not purport to be a complete discussion of, and is qualified in its
entirety by reference to, the Georgia Code and Articles of Incorporation and
Bylaws of each corporation.

AUTHORIZED CAPITAL STOCK

     CBC.  CBC is currently authorized to issue 5,000,000 shares of common
stock, $1.00 par value, of which 1,329,684 shares were outstanding as of
September 30, 1997.

     FSB.  FSB is authorized to issue 10,000,000 shares of FSB Common Stock,
$5.00 par value, of which 553,603 shares were issued and outstanding as of
September 30, 1997.

ACTIONS BY SHAREHOLDERS WITHOUT A MEETING

     CBC.   CBC's Bylaws state that any action required or permitted to be taken
by CBC shareholders may be taken without a meeting by consent of all CBC
shareholders, if the action is set forth in writing and such writing is
delivered to CBC for inclusion in CBC's minute book or filing with CBC's
corporate records.

     FSB.  FSB's Bylaws provide that any action required or permitted to be
taken by FSB shareholders may be taken without a meeting by consent in writing
setting forth the action to be taken and signed by those persons who would be
entitled to vote at a meeting those shares having voting power to cast not less
than the minimum number of votes that would be necessary to 


                                      39
<PAGE>
 
authorize or take such action at a meeting at which all shares entitled to vote
were present and voted.

SPECIAL MEETING OF SHAREHOLDERS

     CBC. CBC's Bylaws provide that special meetings of shareholders may be
called at any time by the Chairman of the CBC Board of Directors, by the CBC
Board of Directors, by the President of CBC, or by CBC upon the written request
of shareholders owning an aggregate of at least 50% of the issued and
outstanding capital stock entitled to vote.

     FSB.  FSB's Bylaws state that special meetings of shareholders may be
called at any time by the FSB Board of Directors, by the President of FSB, or by
FSB, upon the written request of shareholders owning an aggregate of not less
than 25% of the outstanding shares of capital stock entitled to vote.

NUMBER OF DIRECTORS

     CBC.   CBC's Bylaws state that the CBC Board of Directors shall consist of
eight directors, provided, that the number of directors may be increased or
decreased from time to time by the CBC Board of Directors or the CBC
shareholders.

     FSB.  FSB's Articles of Incorporation state that the Board of Directors
shall consist of not less than five nor more than twenty-five directors.  The
FSB Bylaws provide that the number of directors within this range may be fixed
from time to time by the FSB Board of Directors or by the FSB shareholders. The
FSB Board of Directors presently consists of eleven members.

                                    OPINIONS

     The legality of the shares of the CBC Common Stock to be issued in the
Merger will be passed upon by Smith, Gambrell & Russell, LLP, Atlanta, Georgia.
Certain income tax consequences of the Merger will also be passed upon by Smith,
Gambrell & Russell, LLP, Atlanta, Georgia.  Certain matters relating to the
Merger will be passed upon by Powell, Goldstein, Frazer & Murphy LLP, Atlanta,
Georgia and Smith, Gambrell & Russell, LLP for FSB and CBC, respectively.


                         ADJOURNMENT OF SPECIAL MEETING

     The holders of FSB Common Stock will be asked to approve, if necessary, the
adjournment of the FSB Meeting to solicit further votes in favor of the
Agreement.  The proxies of shareholders voting against the Agreement may not be
used by management to vote in favor of an adjournment pursuant to its
discretionary authority.

                             SHAREHOLDER PROPOSALS

     If the Agreement is approved and adopted and the Merger is consummated,
there will be an Annual Meeting of CBC's shareholders, but not of FSB's
shareholders, in 1998.  If the Merger is not consummated, however, FSB
anticipates that its 1998 Annual Meeting will be held in April 1998.  Any
proposal intended to be presented by FSB shareholders for inclusion in FSB's
proxy statement for its 1998 Annual Meeting must be received by FSB at its
principal executive offices no later than December 31, 1997.

                                 OTHER MATTERS

     It is not expected that any matters other than those described in this
Proxy Statement/ Prospectus will be brought before the FSB Meeting.  If any
other matters are presented, however, it is the intention of the persons named
in the proxy to vote such proxy in accordance with the determination of a
majority of the Board of Directors of FSB, including, without limitation, a
motion to adjourn or postpone the FSB Meetings to another time and/or place for
the purpose of soliciting additional proxies in order to approve the Agreement.

  3.1  CONVERSION OF SHARES.  Subject to the provisions of this Article 3, at
       --------------------                                                    
the Effective Time, by virtue of the Merger and without any action on the part
of the holders thereof the shares of the constituent corporations shall be
converted as follows:

      (a)  Each share of CBC Common Stock issued and outstanding immediately
           prior to the Effective Time shall remain issued and outstanding from
           and after the Effective Time.
           
      (b)  Each share of FSB Common Stock (other than Dissenting Shares (defined
           at Section 3.6 below) or shares canceled pursuant to Section 3.3
           below) shall be converted into 1.508 shares (subject to Section 3.5
           hereof) of CBC Common Stock (the "Exchange Ratio"), subject to
           adjustment as hereinafter provided.
           

                                      A-8
<PAGE>
 
  3.2  ANTI-DILUTION PROVISIONS.  In the event FSB or CBC changes the number
       ------------------------                                               
of shares of FSB Common Stock or CBC Common Stock, respectively, issued and
outstanding prior to the Effective Time as a result of a stock split, stock
dividend or similar recapitalization with respect to such stock and the record
date therefor (in the case of a stock dividend) or the effective date therefor
(in the case of a stock split or similar recapitalization) shall be prior to the
Effective Time, the Exchange Ratio shall be proportionately adjusted.

  3.3  SHARES HELD BY FSB OR CBC.  Each of the shares of FSB Common Stock held
       -------------------------                                                
by any FSB Company or by any CBC Company, in each case other than in a fiduciary
capacity or as a result of debts previously contracted, shall be canceled and
retired at the Effective Time and no consideration shall be issued in exchange
therefor.

  3.4  CONVERSION OF STOCK OPTIONS; RESTRICTED STOCK.
       ---------------------------------------------   

        (a) At the Effective Time, all rights with respect to FSB Common Stock
pursuant to stock options ("FSB Options") granted by FSB under the FSB Stock
Plans, which are outstanding at the Effective Time, whether or not exercisable,
shall be converted into and become rights with respect to Surviving Corporation
Common Stock, and the Surviving Corporation shall assume each FSB Option, in
accordance with the terms of the FSB Stock Plan and stock option agreement by
which it is evidenced. From and after the Effective Time, (i) each FSB Option
assumed by the Surviving Corporation may be exercised solely for shares of
Surviving Corporation Common Stock, (ii) the number of shares of Surviving
Corporation Common Stock subject to such FSB Option shall be equal to the number
of shares of FSB Common Stock subject to such FSB Option immediately prior to
the Effective Time multiplied by the Exchange Ratio, and (iii) the per share
exercise price under each such FSB Option shall be adjusted by dividing the per
share exercise price under each such FSB Option by the Exchange Ratio and
rounding down to the nearest cent. Notwithstanding the provisions of clause (ii)
of the preceding sentence, the Surviving Corporation shall not be obligated to
issue any fraction of a share of Surviving Corporation Common Stock upon
exercise of a FSB Option, and any fraction of a share of Surviving Corporation
Common Stock that would otherwise be subject to a converted FSB Option shall
represent the right to receive a cash payment equal to the product of such
fraction and the difference between the "Market Value" of one share of Surviving
Corporation Common Stock and the per share exercise price of such Option. The
"Market Value" of one share of Surviving Corporation Common Stock shall be the
last sales price of such common stock on Nasdaq, or such other exchange or
market system on which Surviving Corporation Common Stock is then traded, (as
reported by The Wall Street Journal or, if not reported thereby, any other
authoritative source selected by the Surviving Corporation) on the last trading
day preceding the date of exercise or, if the Surviving Corporation Common Stock
is not then traded on Nasdaq or an exchange, the "Market Value" of one share of
Surviving Corporation Common Stock shall be established by the Board of
Directors of the Surviving Corporation. It is intended that the foregoing
assumption shall be undertaken in a manner that will not constitute a
"modification" as defined in Section 424 of the Internal Revenue Code, as to any
stock option which is an "incentive stock option." FSB and CBC agree to take all
necessary steps to effect the provisions of this Section 3.4.

       (b) All restrictions or limitations on transfer with respect to FSB
Common Stock awarded under the FSB Stock Plans or any other plan, program or
arrangement of any FSB 

                                      A-9
<PAGE>
 
Company, to the extent that such restrictions or limitations shall not have
already lapsed, and except as otherwise expressly provided in such plan, program
or arrangement, shall remain in full force and effect with respect to shares of
Surviving Corporation Common Stock into which such restricted stock is converted
pursuant to Section 3.1 of this Agreement.

  3.5  FRACTIONAL SHARES.  Notwithstanding any other provision of this
       -----------------                                                
Agreement, each holder of shares of FSB Common Stock exchanged pursuant to the
Merger who would otherwise have been entitled to receive a fraction of a share
of Surviving Corporation Common Stock (after taking into account all
certificates delivered by such holder) shall receive in lieu thereof cash
(without interest) in an amount equal to such fractional part of a share of
Surviving Corporation Common Stock multiplied by $9.88.  No such holder will be
entitled to dividends, voting rights, or any other rights as a shareholder in
respect of any fractional shares.

  3.6  DISSENTING SHAREHOLDERS.  Any holder of shares of FSB Common Stock
       -----------------------                                           
("Dissenting Shares") who perfects such holder's dissenters' rights of appraisal
in accordance with and as contemplated by Article 13 of the GBCC shall be
entitled to receive the value of such shares in cash as determined pursuant to
such provisions of Law; provided, that no such payment shall be made to any
dissenting shareholder unless and until such dissenting shareholder has complied
with the applicable provisions of the GBCC and surrendered to the Surviving
Corporation the certificate or certificates representing the shares for which
payment is being made.  In the event that after the Effective Time a dissenting
shareholder of FSB fails to perfect, or effectively withdraws or loses, such
holder's right to appraisal and of payment for such holder's shares, the
Surviving Corporation shall issue and deliver the consideration to which such
holder of shares of FSB Common Stock is entitled under this Article 3 (without
interest) upon surrender by such holder of the certificate or certificates
representing shares of FSB Common Stock held by such holder.

                                   ARTICLE 4
                              EXCHANGE OF SHARES
                              ------------------

  4.1  EXCHANGE PROCEDURES.  Unless the parties otherwise agree, within three
       -------------------                                                     
business days after the Effective Time, the Surviving Corporation shall cause a
qualified exchange agent (the "Exchange Agent") to mail to the former holders of
FSB Common Stock appropriate transmittal materials which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
theretofore representing shares of FSB Common Stock shall pass, only upon proper
delivery of such certificates to the Exchange Agent.  After the Effective Time,
each holder of shares of FSB Common Stock (other than shares to be canceled
pursuant to Section 3.3 of this Agreement or as to which dissenters' rights have
been perfected as provided in Section 3.6 of this Agreement) issued and
outstanding at the Effective Time shall surrender the certificate or
certificates representing such shares to the Exchange Agent and shall promptly
upon surrender thereof receive in exchange therefor the consideration provided
in Section 3.1 of this Agreement, together with all undelivered dividends or
distributions in respect of such shares (without interest thereon) pursuant to
Section 4.2 of this Agreement.  To the extent required by Section 3.5 of this
Agreement, each holder of shares of FSB Common Stock issued and outstanding at
the Effective Time also shall receive, upon surrender of the certificate or
certificates representing such shares, cash in lieu of any fractional share of
Surviving Corporation Common Stock to which such holder may otherwise be
entitled (without interest).  The 

                                      A-10
<PAGE>
 
Exchange Agent shall not be obligated to deliver the consideration to which any
former holder of FSB Common Stock is entitled as a result of the Merger until
such holder surrenders his or her certificate or certificates representing the
shares of FSB Common Stock for exchange as provided in this Section 4.1. The
certificate or certificates of FSB Common Stock so surrendered shall be duly
endorsed as the Exchange Agent may require. Any other provision of this
Agreement notwithstanding, the Surviving Corporation shall not be liable to a
holder of FSB Common Stock for any amounts paid or property delivered in good
faith to a public official pursuant to any applicable abandoned property Law.

  4.2  RIGHTS OF FORMER FSB SHAREHOLDERS.  At the Effective Time, the stock
       ---------------------------------                                     
transfer books of FSB shall be closed as to holders of FSB Common Stock
immediately prior to the Effective Time and no transfer of FSB Common Stock by
any such holder shall thereafter be made or recognized. Until surrendered for
exchange in accordance with the provisions of Section 4.1 of this Agreement,
each certificate theretofore representing shares of FSB Common Stock (other than
shares to be canceled pursuant to Section 3.3 or as to which dissenters' rights
have been perfected as provided in Section 3.6 of this Agreement) shall from and
after the Effective Time represent for all purposes only the right to receive
the consideration provided in Sections 3.1 and 3.5 of this Agreement in exchange
therefor. To the extent permitted by Law, former holders of record of FSB Common
Stock shall be entitled to vote after the Effective Time at any meeting of
Surviving Corporation shareholders the number of whole shares of Surviving
Corporation Common Stock into which their respective shares of FSB Common Stock
are converted, regardless of whether such holders have exchanged their
certificates representing FSB Common Stock for certificates representing
Surviving Corporation Common Stock in accordance with the provisions of this
Agreement.  Whenever a dividend or other distribution is declared by the
Surviving Corporation on Surviving Corporation Common Stock, the record date for
which is at or after the Effective Time, the declaration shall include dividends
or other distributions on all shares issuable pursuant to this Agreement, but no
dividend or other distribution payable to the holders of record of Surviving
Corporation Common Stock as of any time subsequent to the Effective Time shall
be delivered to the holder of any certificate representing shares of FSB Common
Stock issued and outstanding at the Effective Time until such holder surrenders
such certificate for exchange as provided in Section 4.1 of this Agreement.
However, upon surrender of such FSB Common Stock certificate, both Surviving
Corporation Common Stock certificate (together with all such undelivered
dividends or other distributions without interest) and any undelivered dividends
and cash payments to be paid for fractional share interests (without interest)
shall be delivered and paid with respect to each share represented by such
certificate.  Any portion of the consideration (including the proceeds of any
investments thereof) which had been made payable to the Exchange Agent pursuant
to Section 4.1 of this Agreement that remain unclaimed by shareholders of FSB
for six months after the Effective Time shall be paid to the Surviving
Corporation.  Any shareholders of FSB who have not theretofore complied with
this Article 4 shall thereafter look only to the Surviving Corporation for
payment of their shares of Surviving Corporation Common Stock and unpaid
dividends and distributions on the Surviving Corporation Common Stock
deliverable in respect of each share of FSB Common Stock such shareholder holds
as determined pursuant to this Agreement, in each case, without any interest
thereon.

FSB or one of its Subsidiaries owns all of the issued and outstanding shares of
capital stock of each FSB Subsidiary.  No equity securities of any FSB
Subsidiary are or may become required to be issued (other than to another FSB
Company) by reason of any Rights, and there are no Contracts by which any FSB
Subsidiary is bound to issue (other than to another FSB Company) additional
shares of its capital stock or Rights, or by which any FSB Company is or may be
bound to transfer any shares of the capital stock of any FSB Subsidiary (other
than to another FSB Company), and there are no Contracts by which any FSB
Company is bound to issue (other than to another FSB Company) additional shares
of its capital stock.  There are no Contracts relating to the rights of any FSB
Company to vote or to dispose of any shares of the capital stock of any FSB
Subsidiary.  All of the shares of capital stock of each FSB Subsidiary held by a
FSB Company are fully paid and nonassessable under the applicable Law of the
jurisdiction in which such Subsidiary is incorporated or organized and are owned
by the FSB Company free and clear of any Lien.  Each FSB Subsidiary is either a
bank, a trust company, a savings association or a corporation and is duly
organized, validly existing, and (as to corporations) in good standing under the
Laws of the jurisdiction in which it is organized and has the corporate power
and authority necessary for it to own, lease and operate its Assets and to carry
on its business as now conducted.  Each FSB Subsidiary is duly qualified or
licensed to transact business as a foreign corporation in good standing in the
States of the United States and foreign jurisdictions where the character of its
Assets or the nature or conduct of its business requires it to be so qualified
or licensed, except for such jurisdictions in which the failure to be so
qualified or licensed is not reasonably likely to have,

individually or in the aggregate, a Material Adverse Effect on FSB. Each FSB

defined in the Federal Deposit Insurance Act and applicable regulations
thereunder, and the deposits in which are insured to applicable limits by the
Bank Insurance Fund or the Savings Association Insurance Fund, as appropriate.

individually or in the aggregate, a Material Adverse Effect on FSB, and (b) the
FSB Companies have not taken any action, or failed to take any action, prior to

Memorandum, none of the FSB Companies has executed an extension or waiver of any
- ----------
statute of limitations on the assessment or collection of any Tax due that is
currently in effect, and no unpaid tax deficiency has been asserted in writing
against or with respect to any FSB Company, which deficiency is reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect on
FSB.

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 Internal Revenue Code, except for such instances of noncompliance and
such omissions as are not reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on FSB.

  5.9  ALLOWANCE FOR POSSIBLE LOAN LOSSES.  The allowance for possible loan or
       ----------------------------------                                       
credit losses (the "Allowance") shown on the consolidated balance sheets of FSB
included in the most recent FSB Financial Statements dated prior to the date of

provide for losses relating to or inherent in the loan and lease portfolios
(including accrued interest receivables) of the FSB Companies and other
extensions of credit (including letters of credit and commitments to make loans
or extend credit) by the FSB Companies as of the dates thereof except where the
failure of such Allowance to be so adequate is not reasonably likely to have a
Material Adverse Effect on FSB.

  5.10  ASSETS.  Except as disclosed in Section 5.10 of the FSB Disclosure

                                                             ----------
Memorandum, to the Knowledge of FSB, each FSB Company, its Participation

any of the Laws or Orders which such governmental authority or Regulatory
Authority enforces, where such noncompliance is reasonably likely to have,

practice (within the meaning of the National Labor Relations Act or comparable
state law) or seeking to compel it or any other FSB Company to bargain with any
labor organization as to wages or conditions of employment, nor is there any
strike or other labor dispute involving any FSB Company, pending or, to its
Knowledge, threatened, nor, to its Knowledge, is there any activity involving
any FSB Company's employees seeking to certify a collective bargaining unit or

  5.14  EMPLOYEE BENEFIT PLANS.
        ----------------------   

       (a) FSB has disclosed in Section 5.14 of the FSB Disclosure Memorandum
                                                        ---------------------
and delivered or made available to CBC prior to the execution of this Agreement
copies in each case of all pension, retirement, profit-sharing, deferred
compensation, stock option, employee stock ownership, severance pay, vacation,
bonus, or other incentive plans, all other written employee programs,
arrangements, or agreements, all medical, vision, dental, or other health plans,
all life insurance plans, and all other employee benefit plans or fringe benefit
plans, including, without limitation, "employee benefit plans" as that term is
defined in Section 3(3) of ERISA, currently adopted, maintained by, sponsored in
whole or in part by, or contributed to by any FSB Company or ERISA Affiliate
thereof for the benefit of employees, retirees, dependents, spouses, directors,
independent contractors, or other beneficiaries and under which employees,
retirees, dependents, spouses, directors, independent contractors, or other
beneficiaries are eligible to participate (collectively, the "FSB Benefit
Plans"). Any of the FSB Benefit Plans which is an "employee pension benefit
plan," as that term is defined in Section 3(2) of ERISA, is referred to herein
as a "FSB ERISA Plan."

       (b) Except as to those plans disclosed in Section 5.14(b) of the FSB
Disclosure Memorandum as tax-qualified FSB ERISA Plans (the "FSB Qualified
- ---------------------
Plans"), no FSB Company maintains or previously maintained during the six years
preceding the date of this Agreement a FSB Plan which meets or was intended to
meet the requirements of Code Section 401(a). The Internal Revenue Service has
issued favorable determination letters to the effect that each FSB Qualified
Plan 

                                      A-17
<PAGE>
 
qualifies under Code Section 401(a) and that any related trust is exempt
from taxation under Code Section 501(a), and such determination letters remain
in effect and have not been revoked. Copies of the most recent determination
letters and any outstanding requests for a determination letter with respect to
each FSB Qualified Plan have been delivered or made available to CBC. Except as
disclosed in Section 5.14(b) of the FSB Disclosure Memorandum, no FSB Qualified
                                        ---------------------
Plan has been amended since the issuance of each respective determination
letter. The FSB Qualified Plans currently comply in form with the requirements
under Code Section 401(a), other than changes required by statutes, regulations
and rulings for which amendments are not yet required. No issue concerning
qualification of the FSB Qualified Plans is pending before or is threatened by
the Internal Revenue Service. The FSB Qualified Plans have been administered
according to their terms (except for those terms which are inconsistent with the
changes required by statutes, regulations, and rulings for which changes are not
yet required to be made, in which case the FSB Qualified Plans have been
administered in accordance with the provisions of those statutes, regulations
and rulings) and in accordance with the requirements of Code Section 401(a). No
FSB Company, any ERISA Affiliate or any fiduciary of any FSB Qualified Plan has
done anything that would adversely affect the qualified status of the FSB
Qualified Plans or the related trusts. Any FSB Qualified Plan which is required
to satisfy Code Section 401(k)(3) and 401(m)(2) has been tested for compliance
with, and has satisfied the requirements of, Code Section 401(k)(3) and
401(m)(2) for each plan year ending prior to the date of this Agreement.

       (c) All FSB Benefit Plans are in compliance in all material respects with
the applicable terms of ERISA, the Internal Revenue Code, and any other
applicable Laws the breach or violation of which are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on FSB. To the
Knowledge of FSB, no FSB Company nor any other party has engaged in a
transaction with respect to any FSB Benefit Plan that, assuming the taxable
period of such transaction expired as of the date hereof, would subject any FSB
Company to a tax or penalty imposed by either Section 4975 of the Internal
Revenue Code or Section 502(i) of ERISA in amounts which are reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on FSB.

       (d) Neither FSB nor any ERISA Affiliate of FSB maintains or has during
the six years preceding the date of this Agreement maintained an "employee
benefit pension plan," within the meaning of Section 3(2) of ERISA that is or
was subject to Title IV of ERISA.

       (e) Neither FSB nor any ERISA Affiliate of FSB has any past, present or
future obligation or liability to contribute to any multi-employer plan, as
defined in Section 3(37) of ERISA.

       (f) Except as disclosed in Section 5.14(f) of the FSB Disclosure
                                                             ----------
Memorandum, (i) no FSB Company has any obligations for retiree health and life
- ----------
benefits under any of the FSB Benefit Plans and (ii) there are no restrictions
on the rights of such FSB Company to amend or terminate any such Plan without
incurring any Liability thereunder, which Liability is reasonably likely to have
a Material Adverse Effect on FSB, other than for benefits accrued before the
date of such termination or amendment.

       (g) Except as disclosed in Section 5.14(g) of the FSB Disclosure
                                                             ----------
Memorandum, neither the execution and delivery of this Agreement nor the
- ----------
consummation of the transactions 

                                      A-18

contemplated hereby will (i) result in any payment (including, without
limitation, severance, unemployment compensation, golden parachute or otherwise)
becoming due to any director or any employee of any FSB Company from any FSB
Company under any FSB Benefit Plan or otherwise, (ii) increase any benefits
otherwise payable under any FSB Benefit Plan, or (iii) result in any
acceleration of the time of payment or vesting of any such benefit.

       (h)  The actuarial present values of all accrued deferred compensation
entitlements (including, without limitation, entitlements under any executive
compensation, supplemental retirement, or employment agreement) of employees and
former employees of any FSB Company and their respective beneficiaries, other
than entitlements accrued pursuant to funded retirement plans subject to the
provisions of Section 412 of the Internal Revenue Code or Section 302 of ERISA,
have been reflected on the FSB Financial Statements to the extent required by
and in accordance with GAAP.

       (i) FSB and each ERISA Affiliate of FSB has complied in all material
respects with applicable continuation of coverage requirements of Section 1001
of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, and
ERISA Sections 601 through 608.

       (j) Except as disclosed in Section 5.14(j) of the FSB Disclosure
                                                             ----------
Memorandum, neither FSB nor any ERISA Affiliate of FSB is obligated,
- ----------
contingently or otherwise, under any agreement to pay any amount which would be
treated as a "parachute payment," as defined in Section 280G(b) of the Internal
Revenue Code (determined without regard to Section 280G(b)(2)(A)(ii) of the
Internal Revenue Code).

       (k) Other than routine claims for benefits, there are no actions, audits,
investigations, suits or claims pending, or threatened against any FSB Benefit
Plan, any trust or other funding agency created thereunder, or against any
fiduciary of any FSB Benefit Plan or against the assets of any FSB Benefit Plan.

  5.15  MATERIAL CONTRACTS.  Except as disclosed in Section 5.15 of the FSB

Contract providing for aggregate payments to any Person in any calendar year in
excess of $25,000, excluding "at will" employment arrangements, (b) any Contract
relating to the borrowing of money by any FSB Company or the guarantee by any
FSB Company of any such obligation (other than Contracts evidencing deposit
liabilities, purchases of federal funds, Federal Home Loan Bank advances, fully-
secured repurchase agreements, trade payables, and Contracts relating to
borrowings or guarantees made in the ordinary course of business), (c) any
Contracts between or among FSB Companies, and (d) any other Contract (excluding
this Agreement) or amendment thereto that would be required to be filed as an

Contracts referred to in Sections 5.10 and 5.14(a) of this Agreement, the "FSB
Contracts").  None of the FSB Companies is in Default under any FSB Contract,

<PAGE>
 
in the aggregate, a Material Adverse Effect on FSB. Except as to FHLB advances,
all of the indebtedness of any FSB Company for money borrowed is prepayable at
any time by such FSB Company without penalty or premium.

Knowledge of FSB, threatened (or unasserted but considered probable of assertion
and which if asserted would have at least a reasonable probability of an
unfavorable outcome) against any FSB Company, or against any Asset, interest, or
right of any of them, that is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on FSB, nor are there any Orders of any
Regulatory Authorities, other governmental authorities, or arbitrators

constitute or result in a Default under, or require any Consent pursuant to, or
result in the creation of any Lien on any Asset of any CBC Company under, any
Contract or Permit of any CBC Company, where such Default or Lien, or any

copies in each case of all pension, retirement, profit-sharing, deferred
compensation, stock option, employee stock ownership, severance pay, vacation,
bonus, or other incentive plans, all other written employee programs,
arrangements, or agreements, all medical, vision, dental, or other health plans,
all life insurance plans, and all other employee benefit plans or fringe benefit
plans, including, without limitation, "employee benefit plans" as that term is
defined in Section 3(3) of ERISA, currently adopted, maintained by, sponsored in
whole or in part by, or contributed to by any CBC Company or ERISA Affiliate
thereof for the benefit of employees, retirees, dependents, spouses, directors,
independent contractors, or other beneficiaries and under which employees,
retirees, dependents, spouses, directors, independent contractors, or other
beneficiaries are eligible to participate (collectively, the "CBC Benefit
Plans"). Any of the CBC Benefit Plans which is an "employee pension benefit
plan," as that term is defined in Section 3(2) of ERISA, is referred to herein
as a "CBC ERISA Plan."

       (b) Except as to those plans disclosed in Section 6.14(b) of the CBC
Disclosure Memorandum as tax-qualified CBC ERISA Plans (the "CBC Qualified
- ---------------------
Plans"), no CBC Company maintains or previously maintained during the six years
preceding the date of this Agreement an CBC Plan which meets or was intended to
meet the requirements of Code Section 401(a). The Internal Revenue Service has
issued favorable determination letters to the effect that each CBC Qualified
Plan qualifies under Code Section 401(a) and that any related trust is exempt
from taxation under Code Section 501(a), and such determination letters remain
in effect and have not been revoked. Copies of the most recent determination
letters and any outstanding requests for a determination letter with

Except as disclosed in Section 6.14(b) of the CBC Disclosure Memorandum, no CBC
Qualified Plan has been amended since the issuance of each respective
determination letter. The CBC Qualified Plans currently comply in form with the
requirements under Code Section 401(a), other than changes required by statutes,
regulations and rulings for which amendments are not yet required. No issue
concerning qualification of the CBC Qualified Plans is pending before or is
threatened by the Internal Revenue Service. The CBC Qualified Plans have been
administered according to their terms (except for those terms which are
inconsistent with the changes required by statutes, regulations, and rulings for
which changes are not yet required to be made, in which case the CBC Qualified
Plans have been administered in accordance with the provisions of those
statutes, regulations and rulings) and in accordance with the requirements of
Code Section 401(a). No CBC Company, any ERISA Affiliate or any fiduciary of any
CBC Qualified Plan has done anything that would adversely affect the qualified
status of the CBC Qualified Plans or the related trusts. Any CBC Qualified Plan
which is required to satisfy Code Section 401(k)(3) and 401(m)(2) has been
tested for compliance with, and has satisfied the requirements of, Code Section
401(k)(3) and 401(m)(2) for each plan year ending prior to the date of this

the applicable terms of ERISA, the Internal Revenue Code, and any other
applicable Laws the breach or violation of which are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on CBC. To the
Knowledge of CBC, no CBC Company nor any other party has engaged in a
transaction with respect to any CBC Benefit Plan that, assuming the taxable
period of such transaction expired as of the date hereof, would subject any CBC
Company to a tax or penalty imposed by either Section 4975 of the Internal
Revenue Code or Section 502(i) of ERISA in amounts which are reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on CBC.

       (d) Neither CBC nor any ERISA Affiliate of CBC maintains or has during
the six years preceding the date of this Agreement maintained an "employee
benefit pension plan," within the meaning of Section 3(2) of ERISA that is or
was subject to Title IV of ERISA.

       (e) Neither CBC nor any ERISA Affiliate of CBC has any past, present or
future obligation or liability to contribute to any multi-employer plan, as
defined in Section 3(37) of ERISA.

       (f) Except as disclosed in Section 6.14(f) of the CBC Disclosure
Memorandum, (i) no CBC Company has any obligations for retiree health and life
benefits under any of the CBC Benefit Plans and (ii) there are no restrictions
on the rights of such CBC Company to amend or terminate any such Plan without
incurring any Liability thereunder, which Liability is reasonably likely to have
a Material Adverse Effect on CBC, other than for benefits accrued before the
date of such termination or amendment.

       (g) Except as disclosed in Section 6.14(g) of the CBC Disclosure
                                                             ----------
Memorandum, neither the execution and delivery of this Agreement nor the

any CBC Company from any CBC Company under any CBC Benefit Plan or otherwise,

                                      A-28

(ii) increase any benefits otherwise payable under any CBC Benefit Plan, or
(iii) result in any acceleration of the time of payment or vesting of any such
benefit.

       (h) The actuarial present values of all accrued deferred compensation
entitlements (including, without limitation, entitlements under any executive
compensation, supplemental retirement, or employment agreement) of employees and
former employees of any CBC Company and their respective beneficiaries, other
than entitlements accrued pursuant to funded retirement plans subject to the
provisions of Section 412 of the Internal Revenue Code or Section 302 of ERISA,
have been reflected on the CBC Financial Statements to the extent required by
and in accordance with GAAP.

       (i) CBC and each ERISA Affiliate of CBC has complied in all material
respects with applicable continuation of coverage requirements of Section 1001
of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, and
ERISA Sections 601 through 608.

       (j) Except as disclosed in Section 6.14(j) of the CBC Disclosure
                                                             ----------
Memorandum, neither CBC nor any ERISA Affiliate of CBC is obligated,
- ----------
contingently or otherwise, under any agreement to pay any amount which would be
treated as a "parachute payment," as defined in Section 280G(b) of the Internal
Revenue Code (determined without regard to Section 280G(b)(2)(A)(ii) of the
Internal Revenue Code).

       (k) Other than routine claims for benefits, there are no actions, audits,
investigations, suits or claims pending, or threatened against any CBC Benefit
Plan, any trust or other funding agency created thereunder, or against any
fiduciary of any CBC Benefit Plan or against the assets of any CBC Benefit Plan.

borrowings or guarantees made in the ordinary course of business), (c) any
Contracts between or among CBC Companies, and (d) any other Contract (excluding

consummation of the Merger and shall permit the other Party to make or cause to
be made such investigation of the business and properties of it and its
Subsidiaries and of their respective financial and legal conditions as the other

the representations and warranties of the other Party.

        (b) Each Party shall, and shall cause its advisers and agents to,
maintain the confidentiality of all confidential information furnished to it by
the other Party concerning its and its Subsidiaries' businesses, operations, and

any materials prepared by that Party or any attorney for or other representative
of that Party based upon such confidential information.

        (c) Each Party agrees to give the other Party notice as soon as
practicable after any determination by it of any fact or occurrence relating to
the other Party which it has discovered through the course of its investigation
and which represents, or is reasonably likely to represent, either a material
breach of any representation, warranty, covenant or agreement of the other Party
or which has had or is reasonably likely to have a Material Adverse Effect on
the other Party.

  8.6  PRESS RELEASES.  Prior to the Effective Time, FSB and CBC shall agree

with each other as to the form and substance of any press release or other
public disclosure materially related to this Agreement or any other transaction
contemplated hereby; provided, however, that nothing in this Section 8.6 shall
be deemed to prohibit any Party from making any disclosure which its counsel
deems necessary or advisable in order to satisfy such Party's disclosure
obligations imposed by Law.

       ---------------------   

        (a) Except with respect to this Agreement and the transactions
contemplated hereby, no FSB Company nor CBC Company nor any director, employee,
investment banker, attorney, accountant or other representative thereof
(collectively, "Representatives") retained by any FSB Company or CBC Company, as
the case may be, shall directly or indirectly solicit any Acquisition Proposal
by any Person. Except to the extent necessary to comply with the fiduciary
duties of a Party's Board of Directors as advised by counsel, no FSB Company nor
CBC Company nor Representative thereof, shall furnish any non-public information
that it is not legally obligated to furnish, negotiate with respect to, or enter
into any Contract with respect to, any Acquisition Proposal, but a Party may
communicate information about such an Acquisition Proposal to its shareholders
if and to the extent that it is required to do so in order to comply with its
legal obligations as advised by counsel. Each Party shall promptly notify the
other orally and in writing in the event that it receives any inquiry or
proposal relating to any such transaction.

        (b) Except as set forth herein, neither FSB nor CBC shall (i) withdraw
or modify, or propose to withdraw or modify, in a manner adverse to the other
Party, the approval or recommendation of its Board of Directors of this
Agreement or the Merger, (ii) approve or recommend, or propose to approve or
recommend, any Acquisition Proposal or (iii) enter into any agreement with
respect to any Acquisition Proposal. Notwithstanding the foregoing, if in the
opinion of the Board of Directors of FSB or CBC, as applicable, after
consultation with counsel, failure to do so would be inconsistent with its
fiduciary duties to its shareholders under applicable law, then the Board of
Directors of FSB or CBC, as applicable, may (subject to the terms of this
section (b)) withdraw or modify its approval or recommendation of this Agreement
or the Merger, approve or recommend an Acquisition Proposal, or enter into an
agreement with respect to an Acquisition Proposal, in each case at any time
after the second business day following the receipt of written notice (a "Notice
of Acquisition Proposal") by CBC or FSB, as applicable, advising it that the
other Party has received an Acquisition Proposal, specifying the material terms
and conditions of such proposal and identifying the Person making such proposal;
provided that neither Party shall enter into an agreement with respect to an
Acquisition Proposal unless it shall have furnished the other Party with written
notice no later than 12:00 noon Georgia time one (1) day in advance of any date
that it intends to enter into such agreement.

        (c) In addition to the obligations set forth in section (b) above, each
Party shall immediately advise the other Party orally and in writing of any
request for information or of any Acquisition Proposal, or any inquiry with
respect to or which could lead to an Acquisition Proposal, the material terms
and conditions of such request, Acquisition Proposal or inquiry, and the
identity of the Person making a request, Acquisition Proposal or inquiry. FSB or
CBC, as the case may be, shall keep the other Party fully informed of the status
and details (including amendments or proposed amendments) of any such request,
Acquisition Proposal or inquiry.

        (d) Nothing contained in this Section 8.7 shall prohibit FSB or CBC, as
the case may be, from making any disclosure to its shareholders if, in the
opinion of its Board of Directors, after consultation with counsel, failure to
so disclose would be inconsistent with federal securities laws or its fiduciary
duties to its shareholders under applicable law; provided that the applicable
Party does 

                                      A-38
<PAGE>
 
not, except as permitted by section (b) above, withdraw or modify, or propose to
withdraw or modify, its position with respect to the Merger or approve or
recommend, or propose to approve or recommend, an Acquisition Proposal.

  8.8  ACCOUNTING AND TAX TREATMENT.  Each of the Parties undertakes and
       ----------------------------                                       
agrees to use its reasonable efforts to cause the Merger, and to take no action
which would cause the Merger not, to qualify for treatment as a pooling of
interests for accounting purposes or as a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code for federal income tax purposes.

  8.9  AGREEMENT OF AFFILIATES.  FSB has disclosed in Section 8.9 of the FSB

                       ---------------------

Affiliates of CBC, providing that such Person will not sell, pledge, transfer or

this Agreement and will not sell, pledge, transfer or otherwise dispose of the
shares of Surviving Corporation Common Stock to be held upon consummation of the
Merger except in compliance with applicable provisions of the 1933 Act and the
rules and regulations thereunder.  The Surviving Corporation shall be entitled
to place restrictive legends upon certificates for shares of Surviving
Corporation Common Stock issued to Affiliates of FSB pursuant to this Agreement
to enforce the provisions of this Section 8.9.  CBC shall not be required to
maintain the effectiveness of the Registration Statement under the 1933 Act for

transactions contemplated by this Agreement) to the full extent permitted under
Georgia Law and by FSB'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. Without limiting the foregoing, in any case in
which approval by CBC is required to effect any indemnification, the Surviving
Corporation shall direct, at the election of the Indemnified Party, that the
determination of any such approval shall be made by independent counsel mutually
agreed upon between CBC and the Indemnified Party.

        (b) If the Surviving Corporation 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 transfer

obtained from any Regulatory Authority which is necessary to consummate the

the Merger is a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code, (ii) the exchange in the Merger of FSB Common Stock for
Surviving Corporation Common Stock will not give rise to gain or loss to the
shareholders of FSB with respect to such exchange (except to the extent of any
cash received), (iii) the adjusted tax basis of whole shares of Surviving
Corporation Common Stock received by shareholders of FSB who exchange shares of
FSB Common Stock in the Merger will be the same as the adjusted tax basis of the
shares of FSB Common Stock exchanged therefor (reduced by any amount allocable
to a fractional share interest for which cash is received), (iv) the holding
period of the shares of Surviving Corporation Common Stock received in the
Merger will include the period during which the shares of FSB Common Stock
exchanged therefor were held, provided such shares

<PAGE>
 
of Surviving Corporation Common Stock were held as capital assets at the
Effective Time, (v) the payment of cash to a FSB shareholder in lieu of a
fractional share interest in Surviving Corporation Common Stock will be treated

redeemed by the Surviving Corporation, and (vi) neither FSB nor CBC will
recognize gain or loss as a consequence of the Merger (except for income and
deferred gain recognized pursuant to Treasury regulations issued under Section

        (d) The Parties agree and acknowledge that they have agreed upon
Sections 11.2(b) and (c) above to liquidate the amount of damages they estimate
each Party would suffer in the event of termination of this Agreement in the
circumstances described. Each Party acknowledges that such damages cannot be
estimated exactly, that each Party intends that the foregoing provisions provide
for damages rather than a penalty inserted for the purpose of deterring a Party
from breaching the Agreement and penalizing such Party in the event of such
breach, and that the foregoing amount is agreed upon in good faith as a
reasonable estimate at this time of the damages that each Party would suffer in
the event of termination of the Agreement in the circumstances described.

  11.3  BROKERS AND FINDERS.  Except as set forth in Section 11.3 of the CBC
        -------------------

employed any broker or finder or incurred any Liability for any financial
advisory fees, investment bankers' fees, brokerage fees, commissions, or
finders' fees in connection with this Agreement or the transactions contemplated
hereby.  In the event of a claim by any broker or finder based upon his or its

hold the other Party harmless of and from any Liability in respect of any such

later time to enforce the same or any other provision of this Agreement. No
waiver of any condition or of the breach of any term contained in this Agreement

                                       OF
                     T. STEPHEN JOHNSON & ASSOCIATES, INC.



October 6, 1997


Board of Directors
First Southern Bancshares, Inc.
2727 Panola Road
Lithonia, Georgia  30058

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 First Southern Bancshares,
Inc. ("FSB") in connection with the proposed merger of FSB with and into
Citizens Bancshares Corporation ("CBC"), pursuant to an Agreement and Plan of
Merger (the "Merger Agreement") dated as of October 1, 1997 (the "Merger").  The
Merger Agreement calls for each outstanding share of FSB's common stock to be
converted into 1.508 shares of CBC Common Stock.

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.

TSJ&A was engaged jointly with FSB and CBC in July, 1997 to develop a
preliminary exchange ratio for the two institutions to use to determine the
financial aspects of a merger, issue a final exchange ratio and deliver fairness
opinions to either institution requiring a shareholders vote.

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
FSB or of CBC or any of its subsidiaries.  As such, TSJ&A does not express an
opinion as to the fair market value of FSB. 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 6, 1997.

In arriving at its opinion, TSJ&A reviewed and analyzed audited and unaudited
financial information through June 30, 1997, regarding FSB and CBC and reviewed
its analysis regarding the preliminary exchange ratio prepared as of June 30,
1997.

Board of Directors

Page 2


TSJ&A delivered its preliminary exchange ratio to the merger committee for the
two institutions on July 27, 1997 and rendered an oral opinion at that time that
the shares exchanged based on the preliminary exchange ratio would be fair from
a financial point of view.  The exchange ratio negotiated between FSB and CBC
was the same as the preliminary exchange ratio.

TSJ&A has since reviewed the Merger Agreement and due diligence examination
reports prepared on behalf of the two institutions as well as registration and
draft proxy material to be filed with the Securities and Exchange Commission and
has determined that there has been no material change.  Based on TSJ&A's review
as well as discussions with both parties, the preliminary exchange ratio was
determined to be the final exchange ratio.  This final exchange ratio was issued
as of October 6, 1997.

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 FSB is fair from a financial
point of view.

Sincerely,

/s/ T. Stephen Johnson & Associates, Inc.

             (D)  Excludes or limits the rights of the shares to vote on any
          matter, or to cumulate votes, other than a limitation by dilution
          through issuance of shares or other securities with similar voting
          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 for cash under Code Section 14-2-604; or

             (F)  Cancels, redeems, or repurchases all or part of the shares of
          the class; or


          (5) Any corporate action taken pursuant to a shareholder vote to the
       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 or her
shares under this article may not challenge the corporate action creating his or
her 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:


                                      C-2
<PAGE>
 
         (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 2000
     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.


14-2-1303.  Dissent by nominees and beneficial owners.

     A record shareholder may assert dissenters' rights as to fewer than all the

     (b) If corporate action creating dissenters' rights under Code Section 14-
2-1302 is taken without a vote of shareholders, the corporation shall notify in

was taken and send them the dissenters' notice described in Code Section 14-2-
1322.

         (1) Must deliver to the corporation before the vote is taken written
     notice of his or her intent to demand payment for his or her shares if the
     proposed action is effectuated; and

         (2) Must not vote his or her shares in favor of the proposed action.


                                      C-3

shares under this article.

Section 14-2-1302 is authorized at a shareholders' meeting, the corporation
shall deliver a written dissenters' notice to all shareholders who satisfied the
requirements of Code Section 14-2-1321.

     (b) The dissenters' notice must be sent no later than ten days after the
corporate action was taken and must:

         (1) State where the payment demand must be sent and where and when
     certificates for certificated shares must be deposited;

         (2) Inform holders of uncertificated shares to what extent transfer of
     the shares will be restricted after the payment demand is received;

         (3) Set a date by which the corporation must receive the payment
     demand, which date may not be fewer than 30 nor more than 60 days after the
     date the notice required in subsection (a) of this Code section is
     delivered; and

         (4) Be accompanied by a copy of this article.


14-2-1323.  Duty to demand payment.

     (a) A record shareholder sent a dissenters' notice described in Code
Section 14-2-1322 must demand payment and deposit his or her certificates in
accordance with the terms of the notice.

     (b) A record shareholder who demands payment and deposits his or her shares
under subsection (a) of this Code section retains all other rights of a
shareholder until these rights are canceled or modified by the taking of the
proposed corporate action.

     (c) A record shareholder who does not demand payment or deposit his or her
share certificates where required, each by the date set in the dissenters'
notice, is not entitled to payment for his or her shares under this article.


                                      C-4
<PAGE>

action is taken or the restrictions released under Code Section 14-2-1326.

uncertificated shares retains all other rights of a shareholder until these
rights are canceled or modified by the taking of the proposed corporate action.

     (a) Except as provided in Code Section 14-2-1327, within ten days of the
later of the date the proposed corporate action is taken or receipt of a payment
demand, the corporation shall offer to pay each dissenter who complied with Code
Section 14-2-1323 the amount the corporation estimates to be the fair value of
his or her shares, plus accrued interest.

     (b) The offer of payment must be accompanied by:


         (1) The corporation's balance sheet as of the end of a fiscal year

     that year, and the latest available interim financial statements, if any;

         (2) A statement of the corporation's estimate of the fair value of the
     shares;

         (3) An explanation of how the interest was calculated;

         (4) A statement of the dissenter's right to demand payment under Code
     Section 14-2-1327; and

         (5)  A copy of this article.

     (c) If the shareholder accepts the corporation's offer by written notice to
the corporation within 30 days after the corporation's offer, payment for his or
her shares shall be made within 60 days after the making of the offer or the
taking of the proposed corporate action, whichever is later.


                                      C-5
<PAGE>
 
14-2-1326.  Failure to take action.

     (a) If the corporation does not take the proposed action within 60 days
after the date set for demanding payment and depositing share certificates, the
corporation shall return the deposited certificates and release the transfer
restrictions imposed on uncertificated shares.

     (b) If, after returning deposited certificates and releasing transfer
restrictions, the corporation takes the proposed action, it must send a new
dissenters' notice under Code Section 14-2-1422 and repeat the payment demand
procedure.


14-2-1327.  Procedure if shareholder dissatisfied with payment or offer.

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

         (1) The dissenter believes that the amount offered under Code Section
     14-2-1325 is less than the fair value of his or her shares or that the
     interest 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
section unless he notifies the corporation of his or her demand in writing under
subsection (a) of this Code section within 30 days after the corporation made or
offered payment for his or her shares.

     (c) If the corporation does not offer payment within the time set forth in
subsection (a) of Code Section 14-2-1325:

         (1) The shareholder may demand the information required under
     subsection (b) of Code Section 14-2-1325, and the corporation shall provide
     the information to the shareholder within ten days after receipt of a
     written demand for the information; and

         (2) The shareholder may at any time, subject to the limitations period
     of Code Section 14-2-1332, notify the corporation of his or her own
     estimate of the fair value of his or her shares and the amount of interest
     due and demand payment of his or her estimate of the fair value of his or
     her shares and interest due.

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 and 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 the 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 or her shares,
plus interest to the date of judgment.


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.


                                      C-7
<PAGE>
 
     (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 benefited.

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.

                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 14-2-851 of the Georgia Business Corporation Code provides that a
corporation may indemnify its directors and officers against civil and criminal
liabilities.  Directors and officers may be indemnified against expenses if they
acted in good faith and in a manner reasonably believed to be in or not opposed
to the best interest of the corporation, if they have not been adjudged liable
on the basis of the improper receipt of a personal benefit and, with respect to
any criminal action, if they had no reasonable cause to believe their conduct
was unlawful.  A director or officer may be indemnified against expenses
incurred in connection with a derivative suit if he or she acted in good faith
and in a manner reasonably believed to be in or not opposed to the best interest
of the corporation, except that no indemnification may be made without court
approval if such person was adjudged liable for negligence or misconduct in the
performance of his or her duty to the corporation.  Statutory indemnification is
not exclusive of any rights provided by any bylaw, agreement, vote of
shareholders or disinterested directors or otherwise.

     Article VII of the Registrant's Bylaws provides that the Registrant shall
indemnify a director who has been successful in the defense of any proceeding to
which he was a party or in defense of any claim, issue or matter therein because
he is or was a director of the Registrant, against reasonable expenses incurred
by him in connection with such defense.

     The Registrant's Bylaws also provide that the Registrant is required to
indemnify any director, officer, employee or agent made a party to a proceeding
because he is or was a director, employee or agent against liability incurred in
the proceeding if he acted in a manner he believed in good faith or to be in or
not opposed to the best interests of the Registrant and, in the case of any
criminal proceeding, he had no reasonable cause to believe his conduct was
unlawful.  Determination concerning whether or not the applicable standard of
conduct has been met can be made by (a) a disinterested majority of the Board of
Directors, (b) a majority of a committee of disinterested directors, (c)
independent legal counsel, or (d) an affirmative vote of a majority of shares
held by disinterested stockholders.  No indemnification may be made to or on
behalf of a director, officer, employee or agent (i) in connection with a
proceeding by or in the right of the Registrant in which such person was
adjudged liable to the Registrant or (ii) in connection with any other
proceeding in which such person was adjudged liable on the basis that personal
benefit was improperly received by him.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Registrant
pursuant to the foregoing provisions, the Registrant has been informed that in
the opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

ITEM 22.  UNDERTAKINGS.

  (a) 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:

                                    II-3  
<PAGE>
 
          (i) To include any Prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the Prospectus any facts or events arising after
the effective date of the Registration Statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, represent
a fundamental change in the information set forth in the Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of the securities offered would not exceed
that which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Securities and Exchange Commission (the "Commission") pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective Registration Statement;

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

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

  (c) The undersigned Registrant hereby undertakes (i) that prior to any public
reoffering of the securities registered hereunder through use of a prospectus
which is a part of this registration statement by any person or party who is
deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering prospectus will contain the information called
for by the applicable registration form with respect to reofferings by the
persons who may be deemed underwriters in addition to the information called for
by the other items of the applicable form; (ii) that every prospectus filed
pursuant to paragraph (c)(i) immediately preceding or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933 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 the securities
offered therein and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.

  (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions (see Item 20), or otherwise,
the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 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 of whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

  (e) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, 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.

  (f) 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.

    Re:       Citizens Bancshares Corporation
              Registration Statement on Form S-4
              842,374 Shares of Common Stock (the "Registration Statement")
              -------------------------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel for Citizens Bancshares Corporation (the
"Company") in connection with the proposed public offering of the shares of its
Common Stock covered by the above-described Registration Statement.

     In connection therewith, we have examined the following:

(1)  The Articles of Incorporation of the Company, as amended, certified by the
     Secretary of State of the State of Georgia;

(2)  The Bylaws of the Company, as amended, certified as complete and correct by
     the Secretary of the Company;

(3)  The minute book of the Company, certified as correct and complete by the
     Secretary of the Company;

(4)  Certificate of Good Standing with respect to the Company, issued by the
     Georgia Secretary of State; and

(5)  The Registration Statement (including exhibits thereto).
<PAGE>
 
     Based upon such examination and upon examination of such other instruments
and records as we have deemed necessary, we are of the opinion that:

(A)  The Company has been duly incorporated under the laws of the State of
     Georgia and is validly existing and in good standing under the laws of that
     state.

(B)  The 842,374 shares of Common Stock covered by the Registration Statement
     have been legally authorized and when issued in accordance with the terms
     described in said Registration Statement, will be validly issued, fully
     paid and nonassessable.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to this firm under the caption "Legal Matters" in
the Proxy Statement/Prospectus.  In giving this consent, we do not thereby admit
that we come within the category of persons whose consent is required under
Section 7 of the Securities Act of 1933, or the rules and regulations of the
Securities and Exchange Commission thereunder.

                                       Sincerely,

Re:  Agreement and Plan of Merger under which First Southern Bancshares, Inc.
     will merge with and into Citizens Bancshares Corporation

Gentlemen:

     We have acted as counsel to Citizens Bancshares Corporation ("CBC") in
connection with the proposed merger (the "Merger") of First Southern Bancshares,
Inc. ("FSB"), with and into CBC, pursuant to the terms of and as described in
that certain Agreement and Plan of Merger (the "Merger Agreement") dated as of
October 1, 1997 by and between CBC and FSB, described in CBC's Registration
Statement on Form S-4, to be filed with the Securities and Exchange Commission
on or about October 16, 1997 (the "Registration Statement").  At your request,
in connection with the filing by CBC of the Registration Statement and the Proxy
Statement/Prospectus of CBC and FSB as amended through the date hereof (the
"Proxy Statement/Prospectus") included as part of the Registration Statement, we
are rendering our opinion concerning certain federal income tax consequences of
the Merger.  Unless otherwise indicated, all capitalized terms used in this
opinion have the same meanings given therefor in the Proxy Statement/Prospectus.

     For purposes of rendering our opinion herein, we have conducted an
examination of the Internal Revenue Code of 1986, as amended (the "Code"), and
such other applicable laws, regulations, rulings, decisions, documents and
records as we have deemed necessary.  With respect to factual matters, we have
relied upon the Merger Agreement, including, without limitation, the
representations of CBC and FSB set forth therein, and upon certain statements
and representations made to us in certificates by officers of CBC and FSB,
respectively, in each case without independent verification thereof.  We have,
with your consent, assumed the accuracy and completeness of the statements and
representations contained in such certificates and have 
<PAGE>
 


further assumed that the statements and representations contained in such
certificates will be complete and accurate as of the Effective Time. We have
also relied on the accuracy and completeness of the statements and
representations contained in the Proxy Statement/Prospectus. In addition, for
purposes of this opinion, we have assumed that at least fifty percent (50%) of
the outstanding shares of FSB Common Stock will be exchanged for CBC Common
Stock in the Merger, and that the shares of FSB Common Stock constitute capital
assets in the hands of each holder thereof.

     Based on the foregoing, and subject to the qualifications set forth below,
we are of the opinion that under the Code:

  (1) The Merger will constitute a reorganization under Code (S)(S)368(a)(1)(A)
and CBC and FSB will each be a party to the reorganization within the meaning of
Code (S)368(b).

  (2) Holders of shares of FSB Common Stock who exchange such shares solely for
shares of CBC Common Stock will not recognize gain or loss on the exchange.

  (3) The federal income tax basis of shares of CBC Common Stock received in
exchange for shares of FSB Common Stock will be equal to the holder's basis of
the shares of FSB Common Stock surrendered in exchange therefor (reduced by the
basis allocable to any fractional interest in any share of CBC Common Stock for
which cash is received), and the holding period of such CBC Common Stock will
include the holding period of the shares of FSB Common Stock surrendered in
exchange therefor.

  (4) The receipt of cash in lieu of fractional shares will be treated as if the
fractional shares were distributed as part of the exchange and then redeemed by
CBC, and capital gain or loss will be recognized in an amount equal to the
difference between the cash received and the basis of the fractional share of
CBC Common Stock surrendered.

  (5) Neither FSB nor CBC will recognize gain or loss as a consequence of the
Merger.
 
     The opinions expressed herein are based upon our interpretation of existing
legal authorities, and no assurance can be given that such interpretations would
be followed if the exchange of shares contemplated by the Merger became the
subject of administrative or judicial proceedings.  Statements of opinion herein
are opinions only and should not be interpreted as guarantees of the current
status of the law, nor should they be accepted as a guarantee that a court of
law or administrative agency will concur in such statement.

     No opinion is expressed with respect to any of the following:

  (1) The appropriate method to determine the fair market value of any stock or
other consideration received in any sale or exchange;
<PAGE>
 


  (2) The state, local or foreign tax consequences of any aspect of the Merger;
or

  (3) The federal income tax consequences of any aspect of the Merger to holders
of FSB Common Stock who are subject to special tax treatment for federal income
tax purposes, including among others, life insurance companies, tax exempt
entities and foreign taxpayers, or to holders of FSB Options which are exchanged
for or converted into options or warrants to acquire CBC Common Stock.

     We expressly consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement, and to the
references to this opinion in the Proxy Statement/Prospectus.  In giving this
opinion, we do not hereby admit that we are in the category of persons whose
consent is required under Section 7 of the Securities Act of 1933, as amended.

                                    Very truly yours,

                                    SMITH, GAMBRELL & RUSSELL, LLP
