                                    SUMMARY

     The following is a summary of certain information contained elsewhere in
this Proxy Statement/Prospectus.  This summary is not intended to be a complete
description of the matters covered in this Proxy Statement/Prospectus and is
subject to and qualified in its entirety by reference to the more detailed
information contained elsewhere in this Proxy Statement/Prospectus, including
the Appendices hereto, and in the documents incorporated by reference in this
Proxy Statement/Prospectus.  A copy of the Merger Agreement is set forth in
Appendix A to this Proxy Statement/Prospectus and reference is made thereto for
a complete description of the terms of the Merger.  Shareholders are urged to
read carefully the entire Proxy Statement/Prospectus, including the Appendices.
As used in this Proxy Statement/Prospectus, the terms "CSBI" and "BCG" refer to
such corporations, respectively, and where the context requires, CSBI and its
subsidiaries or BCG and its subsidiaries.


PARTIES TO THE MERGER

     CSBI.  CSBI is a Georgia corporation and a bank holding company registered
under the Bank Holding Company Act of 1956, as amended (the "BHC Act").  Through
its banking subsidiaries, CSBI provides a wide range of commercial and retail
banking services  in Georgia and Tennessee.  CSBI currently owns ten national
and state chartered bank subsidiaries which operate 22 full service banking
offices, 2 limited service facilities and 19 automated teller machines ("ATMs")
in nine counties in Georgia and one county in Tennessee.

     For the year ended December 31, 1996, CSBI reported net income of $9.370
million.  For the three months ended March 31, 1997, CSBI reported net income of
$1.922 million.  As of March 31, 1997, CSBI had total consolidated assets of
$768.305 million and consolidated shareholders' equity of $76.300 million.

     CSBI is continually evaluating acquisition opportunities and frequently
conducts due diligence activities in connection with possible acquisitions.  As
a result, acquisition discussions and, in some cases, negotiations frequently
take place and future acquisitions involving cash, debt or equity securities can
be expected.  Acquisitions typically involve the payment of a premium over book
and market value, and therefore some dilution of CSBI's book value and/or net
income per common share may occur in connection with any such future
acquisitions.  See "PRO FORMA COMBINED FINANCIAL DATA."

     CSBI's principal executive offices are located at 60 Main Street West,
Dahlonega, Georgia, and its telephone number is 706/864-1111.  For additional
information regarding CSBI and its business,  see "AVAILABLE INFORMATION,"
"INCORPORATION OF CERTAIN INFORMATION BY REFERENCE."

     BCG.  BCG is a Georgia corporation and a bank holding company registered
under the BHC Act. Through its banking subsidiaries BCG provides a wide range of
commercial and retail banking services. BCG owns  two national bank
subsidiaries which operate 10 full service banking offices and 3 ATMs in 7
counties in Georgia.  Pursuant to the Merger Agreement, BCG will merge with and
into CSBI, with CSBI resulting as the surviving entity.  BCG's two banking
subsidiaries will become wholly-owned subsidiaries of CSBI.

     For the year ended December 31, 1996, BCG reported net income of $3.313
million.  For the three months ended March 31, 1997, BCG reported net income of
$944 thousand.  As of March 31, 1997, BCG had total assets of $302.506 million
and shareholders' equity of $27.440 million.

     BCG's principal executive offices are located at 4951 Forsyth Road, Macon,
Georgia, and its telephone number is 912/757-2000.  For additional information
regarding BCG and its business, see "AVAILABLE INFORMATION," "INCORPORATION OF
CERTAIN INFORMATION BY REFERENCE," "DESCRIPTION OF BCG," "SUMMARY - Selected
Financial Data," and "CERTAIN REGULATORY CONSIDERATIONS."

SPECIAL MEETING; RECORD DATE

     The Special Meeting will be held at 1:00 p. m., Macon time on August __,
1997, at the main office of BCG, located at 4951 Forsyth Road, Macon, Georgia.
At the Special Meeting, BCG's shareholders will consider and vote upon  approval
of the Merger Agreement and the consummation of the transactions contemplated
therein.  BCG's Board of Directors has fixed the close of business on August __,
1997 as the record date for determining the BCG shareholders entitled to receive
notice of and to vote at the Special Meeting (the "Record Date").  As of the

                                       6
<PAGE>
 
Record Date, there were 2,274,357 shares of BCG Common Stock issued and
outstanding and entitled to be voted at the Special Meeting.  For additional
information with respect to the Special Meeting, including the Record Date and
votes required for approval, see "GENERAL INFORMATION."

THE MERGER

     General.  The Merger Agreement provides that BCG shall merge with and into
CSBI, which shall be the surviving corporation of the Merger.  Thereafter, BCG
shall cease to exist and BCG's subsidiaries will become wholly-owned
subsidiaries of CSBI.  At the time the Merger becomes effective, each
outstanding share of BCG Common Stock (excluding treasury shares) shall cease to
be outstanding and shall be converted into and exchanged for the right to
receive shares of CSBI Common Stock.  If the Merger Agreement is approved at the
Special Meeting, all required governmental and other consents and approvals are
obtained, and all of the other  conditions to the obligations of the parties to
consummate the Merger are either satisfied or waived (as permitted), the Merger
will be consummated.  A copy of the Merger Agreement is set forth in Appendix A
to this Proxy  Statement/Prospectus.  See "THE MERGER."

     Merger Consideration.  The Merger Agreement provides that, at the effective
time of the Merger, each outstanding share of BCG Common Stock (excluding shares
held by BCG or any of its subsidiaries or by CSBI or any of its subsidiaries, in
each case other than a fiduciary capacity or as a result of debts previously
contracted) shall cease to be outstanding and shall be converted into and
exchanged for the right to receive 1.35 shares of CSBI Common Stock.  See "THE
MERGER -Merger Consideration."

     Votes Required . Approval of the Merger Agreement and consummation of the
transactions contemplated therein requires the affirmative vote of the holders
of a majority of the outstanding shares of BCG Common Stock entitled to vote at
the Special Meeting.  As of the Record Date, BCG's directors and executive
officers, and their affiliates, held approximately 57.25% of the outstanding
shares of BCG Common Stock entitled to vote at the Special Meeting.  As of the
Record Date, CSBI, its  directors and executive officers, and their affiliates,
owned 1,700 shares of the outstanding shares of BCG Common Stock.   The vote of
the shareholders of CSBI is not required as a condition to consummation of the
transaction. See "GENERAL INFORMATION - Votes Required."

     Recommendation of the BCG Board of Directors.  The Board of Directors of
BCG believes that the Merger is in the best interests of BCG and its
shareholders and has unanimously approved the Merger Agreement and the
consummation of the transactions contemplated therein.  BCG's Board of Directors
unanimously recommends that the shareholders vote FOR approval of the Merger
Agreement and the consummation of the transactions contemplated therein.  In
deciding to approve the Merger Agreement and the consummation of the
transactions contemplated therein, BCG's Board of Directors considered a number
of factors, including the compatibility of the operations of BCG and CSBI, and
the financial condition, results of operations, and future prospects of BCG and
CSBI.  See "THE MERGER - Reasons for the Merger."

     Effective Time.  If the Merger is approved by the requisite vote of BCG's
shareholders, all required governmental and other consents and approvals are
obtained, and the other conditions to the obligations of the parties to
consummate the Merger are either satisfied or waived (as permitted), the Merger
will be consummated and will become effective on the date and at the time that a
Certificate of Merger, is filed with the Secretary of State of the State of
Georgia (the "Effective Time").  Assuming satisfaction of all conditions to
consummation, the Merger is expected to be made effective during the fourth
quarter of 1997.  CSBI and BCG each has the right, acting unilaterally, to
terminate the Merger Agreement should the Merger not be consummated by December
31, 1997.  See "THE MERGER - Effective Time" and "Amendment, Waiver, and
Termination."

     Delivery of BCG Certificates.  Promptly after the Effective Time, each
record holder of shares of BCG Common Stock outstanding at the Effective Time
will be mailed a transmittal letter (with instructions) to use in effecting the
surrender and cancellation of those certificates in exchange for CSBI Common
Stock.  CSBI shall not be obligated to deliver the consideration to which any
former holder of BCG Common Stock is entitled until such holder surrenders such
holder's certificate or certificates representing such holder's shares for
exchange.  The certificate or certificates so surrendered shall be duly endorsed
as CSBI may require.  See "THE MERGER - Distribution of  CSBI Certificates."

     Certain Federal Income Tax Consequences. The Merger is intended to be a
tax-free reorganization within the meaning of section 368(a) of the Code.
Generally, no gain or loss should be recognized for federal income tax 

                                       7
<PAGE>
 
purposes by BCG shareholders as a result of the Merger, except that gain or loss
will be recognized with respect to cash received in lieu of fractional shares. A
condition to consummation of the Merger is the receipt by each of CSBI and BCG
of an opinion of Troutman Sanders LLP, counsel to CSBI, as to the qualification
of the Merger as a tax-free reorganization and certain other federal income tax
consequences of the Merger. The opinion will be delivered by Troutman Sanders
LLP upon closing of the Merger in the form which has been included as an exhibit
to the Registration Statement regarding this Proxy Statement/Prospectus. See
"THE MERGER - Certain Federal Income Tax Consequences."

     BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE
PARTICULAR CIRCUMSTANCES OF EACH SHAREHOLDER AND OTHER FACTORS, EACH HOLDER OF
BCG COMMON STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISER TO DETERMINE
THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE
APPLICATION AND EFFECT OF STATE AND LOCAL INCOME AND OTHER TAX LAWS).

     Interests of Certain Persons in the Merger.  Certain members of BCG's
management and the Board of Directors of BCG have interests in the Merger in
addition to their interests as shareholders of BCG generally.  As of July 24,
1997, the directors and officers of BCG owned 1,015 shares of CSBI Common Stock
and the directors and executive officers of CSBI owned 1,700 shares of BCG
Common Stock.  See "THE MERGER - Management and Operations After the Merger" and
"Interests of Certain Persons in the Merger."

     For information regarding the number of shares and percentage ownership of
CSBI Common Stock that will be acquired by each of the directors and executive
officers of BCG, see "THE MERGER - Interests of Certain Persons in the Merger."

     Conditions to Consummation.  Consummation of the Merger is subject to
various conditions, including among other matters the following material
conditions:   (i) approval of the Merger Agreement by BCG shareholders; (ii)
receipt of all governmental and other consents and approvals necessary to permit
consummation of the Merger, including those of the Board of Governors of the
Federal Reserve System (the "Federal Reserve") and the Department of  Banking
and Finance of the State of Georgia (the "DBF"); and (iii) satisfaction of
certain other usual conditions, including the receipt of the tax opinion
discussed above.  See "THE MERGER - Conditions to Consummation" and "Amendment,
Waiver, and Termination."

     Regulatory Approvals. The Merger is subject to the prior approval of the
Federal Reserve and the DBF.  On July 15, 1997, the DBF approved CSBI's
application to acquire BCG subject to BCG shareholder approval and the
maintenance of the BCG Banks' capital adequacy by CSBI after consummation of the
Merger. On July 11, 1997 the Federal Reserve approved CSBI's application to
acquire BCG by Merger.   See "THE MERGER - Regulatory Approvals."

     Conduct of Business Pending the Merger. CSBI and BCG have each agreed in
the Merger Agreement to, among other things, operate their respective businesses
and the business of their respective subsidiaries only in the ordinary course
and to take no action that would adversely affect their respective abilities to
perform their respective covenants and agreements under the Merger Agreement. In
addition, each party has agreed not to take certain actions relating to their
respective operations and their respective subsidiaries pending consummation of
the Merger without the prior written consent of the other party, except as
otherwise permitted by the Merger Agreement, including, among other things: (i)
becoming responsible for any obligation for borrowed money in excess of an
aggregate of $100,000, except in accordance with past practices; (ii) paying any
dividends, or otherwise acquiring or exchanging any shares of its capital stock
other than in accordance with past practice, or, subject to certain exceptions,
issuing any additional shares of its capital stock or giving any person the
right to acquire any such shares, or issuing any long-term debt; (iii) acquiring
control over any other entity; (iv) subject to certain exceptions, granting any
increase in compensation or benefits, or paying any bonus, to any of its
directors, officers or employees; (v) modifying or adopting any employee benefit
plans, including any employment contract; or (vi) taking any other action not in
the ordinary course of business.  See "THE MERGER - Conduct of Business Pending
the Merger."

     Termination.  The Merger Agreement may be terminated, and the Merger
abandoned, at any time prior to the Effective Time by mutual consent of the
Boards of Directors of BCG and CSBI.  In addition, the Merger Agreement may be
terminated, and the Merger abandoned, prior to the Effective Time by either CSBI
or BCG if (i) 

                                       8
<PAGE>
 
the other party breaches and does not timely cure any representation, warranty,
covenant or other agreement contained in the Merger Agreement and such breach,
individually or in the aggregate, has a Material Adverse Effect, as defined in
the Merger Agreement, on the non-breaching party (ii) any consent or approval of
certain regulatory authorities is denied by final nonappealable action of such
authority, or, (iii) the Merger has not been consummated by December 31, 1997,
or by either party in the event that the Board of Directors of the other party
shall have failed to reaffirm, following a written request by such party for
such reaffirmation after the other party shall have received any inquiry or
proposal with respect to an "Acquisition Proposal" (as defined in the Merger
Agreement), its approval of the Merger and the transactions contemplated by the
Merger Agreement (to the exclusion of any other "Acquisition Proposal"), or
shall have resolved not to reaffirm the Merger. See "THE MERGER -Amendment,
Waiver, and Termination."

     Accounting Treatment.  It is anticipated that the Merger will qualify as a
"pooling of interests" for financial reporting purposes.  See "THE MERGER -
Accounting Treatment."

     Resale of CSBI Common Stock.  The CSBI Common Stock issued in connection
with the Merger will be freely transferable by the holders of such shares,
except for those holders who may be deemed to be "affiliates" (generally
including directors, certain executive officers, and 10% or more shareholders)
of BCG or CSBI under applicable federal securities laws.  See "THE MERGER -
Resale of CSBI Common Stock."

     Dissenters' Rights.  Under Georgia corporate law, dissenters' rights of
appraisal do not exist because shares of BCG Common Stock are publicly traded.

RECENT DEVELOPMENTS

     On July 16, 1997, CSBI announced a second quarter net loss of $741,735. The
loss resulted from special charges of $2,725,000 net of related taxes.  The
second quarter 1997 net loss per share was $0.10.  CSBI's year-to-date net
earnings for 1997 were $1,180,000 or $0.15 per share as compared to $4,811,000
or $0.62 per share for 1996.  Of the net $2,725,000 special charges,
approximately $2,350,000 relates to provision for loan losses to reflect the
results of an in depth study of the loan portfolio at two subsidiary banks where
recent management changes have occurred and a revision of the estimation process
used by CSBI in the second quarter of 1997.  The remainder of the special
charges were primarily due to write offs of certain equipment that has been
determined to be obsolete and the buy out of various vendor contracts and
leases.  Before these special charges, second quarter 1997 net income was
$1,983,000 or $0.25 per share.  CSBI's net income per share in the second
quarter 1996 was $0.34, which included a one time gain of approximately $350,000
after tax, resulting primarily from the recovery of the principal of previously
charged-off municipal securities.

                              GENERAL INFORMATION
                                        

SPECIAL MEETING

     This Proxy Statement/Prospectus is being furnished by BCG to its
shareholders in connection with the solicitation of proxies by the Board of
Directors of BCG from holders of the outstanding shares of BCG Common Stock for
use at the Special Meeting of shareholders of BCG to be held at the main office
of BCG, located at 4951 Forsyth Road, Macon, Georgia, at 1:00 p.m., Macon time,
on August __, 1997 and at any adjournments and postponements thereof, to
consider and vote upon a proposal to approve the Merger Agreement and
consummation of the transactions contemplated therein, and to transact such
other business as may properly come before the Special Meeting.

     This document is also being furnished by CSBI to BCG shareholders as a
prospectus in connection with the issuance by CSBI of shares of CSBI Common
Stock upon consummation of the Merger.

     The Merger Agreement provides that BCG will merge with and into CSBI. CSBI
will be the surviving corporation of the Merger and will continue to be governed
by the laws of the State of Georgia. BCG's national banking subsidiaries, First
South Bank, National Association and Ameribank, National Association
("collectively, BCG Banks") will remain in existence under their respective
Articles of Association and Bylaws as wholly-owned subsidiaries of CSBI. At the
Effective Time, each share of issued and outstanding BCG Common Stock (excluding
treasury shares) shall cease to be outstanding and shall be converted into and
exchanged for the right to receive shares of CSBI Common Stock.  All shares of
BCG Common Stock outstanding immediately before the Effective Time shall as a
result of the Merger no longer be outstanding and shall automatically be
canceled, retired and cease to exist, and each holder of a BCG stock certificate
shall cease to have any rights with respect thereto, except the right to receive
the shares of CSBI to be issued in consideration therefor upon the surrender of
such certificate, cash in lieu of fractional shares and without interest.  See
"THE MERGER - Merger Consideration."

     If the Merger Agreement is approved at the Special Meeting, all required
governmental and other consents and approvals are obtained, and all of the other
conditions to the obligations of the parties to consummate the Merger are either
satisfied or waived (as permitted), the Merger will be consummated.  See "THE
MERGER - Effective Time."

RECORD DATE, SOLICITATION, AND REVOCABILITY OF PROXIES

     The BCG Board of Directors has fixed the close of business on August __,
1997 as the Record Date for determining the BCG shareholders entitled to receive
notice of and to vote at the Special Meeting.  Only holders of record of BCG
Common Stock as of the Record Date are entitled to notice of and to vote at the
Special Meeting.  As of the Record Date, there were 2,274,357 shares of BCG
Common Stock issued and outstanding and held by approximately 883 record
holders.  Holders of BCG Common Stock are entitled to one vote on each matter
considered and voted on at the Special Meeting for each share of BCG Common
Stock held of record at the close of business on the Record Date.  The presence,
in person or by properly executed proxy, of the holders of a majority of the
outstanding shares of BCG Common Stock entitled to vote at the Special Meeting
is necessary to constitute a quorum at the Special Meeting.  Abstentions will be
counted, but "broker non-votes" will not be counted, as shares present for
purposes of determining the presence of a quorum.  Neither abstentions nor
"broker non-votes" will be counted as votes cast for purposes of determining
whether a proposal has received sufficient votes for approval.

     Proxies in the form enclosed are solicited by BCG's Board of Directors.
Shares of BCG Common Stock represented by properly executed proxies, if such
proxies are received in time and are not revoked, will be voted in accordance
with the instructions indicated on the proxies.  IF NO INSTRUCTIONS ARE
INDICATED, SUCH PROXIES WILL BE VOTED FOR APPROVAL OF THE MERGER AGREEMENT AND
CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED THEREIN, AND AS DETERMINED  BY A
MAJORITY OF THE MEMBERS OF THE BCG BOARD OF DIRECTORS AS TO ANY OTHER MATTER
THAT MAY COME BEFORE THE SPECIAL MEETING.  ANY HOLDER OF BCG COMMON STOCK 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 

                                       14
<PAGE>
 
HAVE VOTED IN FAVOR OF APPROVAL OF THE MERGER AGREEMENT AND CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED THEREIN.

     A BCG shareholder who has given a proxy may revoke it at any time prior to
its exercise at the Special Meeting, by (i) giving written notice of revocation
to the Secretary of BCG, or (ii) properly submitting to BCG a duly executed
proxy bearing a later date.  All written notices of revocation and other
communications with respect to revocation of proxies should be addressed to BCG
as  follows: Bank Corporation of Georgia, 4951 Forsyth Road, Macon, Georgia
31203-4099, Attention:  Corporate Secretary.

     The expense of soliciting proxies for the Special Meeting will be paid for
by BCG.  In addition to the solicitation of shareholders of record by mail,
telephone or personal contact, BCG will be contacting brokers, dealers, banks or
voting trustees or their nominees who can be identified as record holders of BCG
Common Stock; such holders, after inquiry by BCG, will provide information
concerning the quantity of proxy and other materials needed to supply such
materials to beneficial owners, and BCG will reimburse them for the expense of
mailing the proxy materials to such persons.

VOTE REQUIRED

     Approval of the Merger Agreement and consummation of the transactions
contemplated therein requires the affirmative vote of a majority of the
outstanding shares of BCG Common Stock.  The Merger Agreement and the
consummation of the transactions contemplated therein do not require the
approval of the holders of CSBI Common Stock.

     As of the Record Date, BCG's directors and executive officers, and their
affiliates, held approximately  57.25% of the outstanding shares of BCG Common
Stock entitled to vote at the Special Meeting. As of the Record Date, CSBI, its
directors and executive officers, and their affiliates, held less than 1% of the
outstanding  shares of BCG Common Stock.

RECOMMENDATION OF BCG'S BOARD OF DIRECTORS

     For the reasons described below, the Board of Directors of BCG unanimously
adopted the Merger Agreement, believes the Merger is in the best interests of
BCG and its shareholders, and unanimously recommends that shareholders of BCG
vote FOR approval of the Merger Agreement and the consummation of the
transactions contemplated therein.  See "THE MERGER - Reasons for the Merger."

                                   THE MERGER

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

GENERAL

     The Merger Agreement provides that BCG shall merge with and into CSBI. CSBI
will be the surviving corporation of the Merger and will continue to be governed
by the laws of the State of Georgia.  At the time the Merger becomes effective,
each share of issued and outstanding BCG Common Stock shall cease to be
outstanding and (excluding treasury shares) shall be converted into and
exchanged for the right to receive shares of CSBI Common Stock.  If the Merger
Agreement is approved at the Special Meeting, all required governmental and
other consents and approvals are obtained, and all other conditions to the
obligations of the parties to consummate the Merger are either satisfied or
waived (as permitted), the Merger will be consummated.  A copy of the Merger
Agreement is set forth in Appendix A of this Proxy Statement/Prospectus.  See
"Merger Consideration."

BACKGROUND OF THE MERGER

     In January of 1997, James A. Faulkner, the Chief Executive Officer of CSBI,
and Joseph W. Evans, the Chief Executive Officer of BCG, met to discuss the
possibility of a combination between CSBI and BCG.  Due to their long term
relationship and because of Mr. Faulkner's three years of service as a director
of BCG (which ended May 22, 1996), they were familiar with each other's
companies and readily saw many of the benefits of a merger.  Preliminary pro-
formas reflecting their collective estimates of internal growth rates, potential
savings, and revenue enhancements were run and seemed to validate their
perceptions of the earnings potential that could be created.

     The two Chief Executive Officers next met with a management consultant who
had worked with both companies to discuss issues of organizational integration
and cultural compatibility.  They tentatively agreed on their respective roles
should the Merger take place as well as an organizational chart.

     In February of 1997, the discussion group was expanded to include the
Chairmen of CSBI and BCG and it was decided that the Chief Executive Officers
would negotiate an exchange ratio for presentation to the respective boards.  On
February 26, 1997, Joseph W. Evans and William H. Anderson, II, the Chairman of
BCG, discussed the proposed transaction with the Board of BCG.  The Board of
Directors discussed the business of CSBI and the opportunity presented by the
proposed merger.

     The Board of Directors of BCG approved the merger with an exchange ratio of
1.4 shares of CSBI for each share of BCG on March 13, 1997.  That ratio was
subsequently adjusted to 1.33 to 1 after discovering a computational error in
determining BCG's "fully diluted" shares and the exchange ratio was approved by
the Board of Directors of BCG on March 31, 1997.

     On March 31, 1997, the parties executed the Agreement and issued a joint
press release on April 1, 1997 announcing the execution of the Agreement.  On
July 11, 1997, the parties amended the Agreement primarily based on a decision
to conform the loan loss reserve practices followed by the parties.  As a
result, the exchange ratio was adjusted to 1.35 to 1 and the parties' due
diligence period was extended to July 31, 1997.  See "Recent Developments. "

REASONS FOR THE MERGER

     The BCG Board of Directors, after consideration of relevant business,
financial, legal and market factors, approved the Merger Agreement.  BCG's Board
of Directors did not assign any relative or specific weight to the factors
considered.  The factors considered included:

     (i) Comparing BCG's continuing as an independent entity to combining with
CSBI, particularly as to shareholder value.  The Board considered the benefits
that could reasonably be expected to accrue to BCG  shareholders from the
Merger, including the premium offered over BCG's then-current stock price or
stock price unaffected by acquisition speculation and the likelihood of a higher
stock price for BCG Common Stock than would be achieved by BCG operating on an
independent basis unaffected by acquisition speculation. The Board was of the
view that the Merger Consideration represented a fair multiple of BCG's per
share book value and earnings.

     (ii) Certain financial and other information concerning CSBI.  Such
information included, among other things, information with respect to the
business, operations, condition and future prospects of CSBI, particularly its
capital position and asset quality, including its ability to pay dividends and
its access to growing market areas in northern Georgia and southeastern
Tennessee not served by BCG whose markets are located in central and southeast
Georgia.

     (iii)  The anticipated synergies, efficiencies and economies of scale that
could be achieved by incorporating BCG's management expertise into a larger
organization.

     (iv) The Board's review, based upon its due diligence investigation of
CSBI, of the business, operations, earnings and financial condition of CSBI on
an historical and prospective basis, and the enhanced 

                                       16
<PAGE>
 
opportunities for growth and expanded operations which will be made possible
through coordinated efforts with other CSBI subsidiaries, such as increasing the
aggregate lending limits of the collective institutions.

     (v) The Board's consideration of the alternative to the Merger of remaining
independent and growing internally or having discussions with other potential
merger partners.  The Board determined that a combination with CSBI would result
in greater long term value to the shareholders of BCG than either remaining
independent or being acquired by another institution.  Factors considered in
reaching this conclusion included the increased liquidity provided to
shareholders of BCG through acquiring stock in CSBI, a publicly traded company
with greater liquidity than BCG, CSBI's overall performance historically and on
a prospective basis.

     (vi) The Board additionally considered, discussed and determined that the
benefits of merging with CSBI would far outweigh the dilution in voting power
which BCG shareholders will experience upon consummation of the Merger as a
result of owning a smaller portion of the total CSBI Common Stock.

     (vii)  The non-financial terms and structure of the Merger, in particular,
the fact that the Merger is anticipated to be tax-free to BCG shareholders.

     (viii)  The likelihood of the Merger being approved by the appropriate
regulatory authorities.

     (ix) The impact generally of the Merger on the various constituencies
     served by BCG.

     THE BOARD OF DIRECTORS OF BCG UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR
APPROVAL OF THE MERGER AGREEMENT AND CONSUMMATION OF THE TRANSACTIONS
CONTEMPLATED THEREIN.

MERGER CONSIDERATION

     The Merger Agreement provides that, at the Effective Time, each issued and
outstanding share of BCG Common Stock (excluding shares held by BCG or by CSBI
or any of its subsidiaries, in each case other than in a fiduciary capacity or
as a result of debts previously contracted)  shall cease to be outstanding and
shall be converted into and exchanged for the right to receive 1.35 shares of
CSBI Common Stock (the "Merger Consideration" ).

     In the event BCG or CSBI changes the number of shares of BCG Common Stock
or CSBI Common Stock, or other common stock equivalents, on a fully diluted
basis, 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 shall be prior to the Effective Time, the Merger
Consideration shall be proportionately adjusted.

FRACTIONAL SHARES

     Pursuant to the terms of the Merger Agreement, each holder of shares of BCG
Common Stock exchanged pursuant to the Merger,  who would otherwise have been
entitled to receive a fraction of a share of CSBI Common Stock shall receive, in
lieu thereof, cash (without interest) in an amount equal to such fractional part
of a share of CSBI Common Stock multiplied by the market value per share of CSBI
Common Stock  at the Effective Time, which shall be the last sale price of such
common stock on the Nasdaq National Market (as reported by The Wall Street
Journal or, if not reported thereby, any other authoritative source) on the last
business day preceding the Effective Time.  No such holder will be entitled to
dividends, voting rights, or any other rights as a shareholder in respect of any
fractional shares.

EFFECTIVE TIME

     If the Merger Agreement is approved by the requisite vote of BCG
shareholders, and all other required governmental and other consents and
approvals are received, and if the other conditions to the obligations of the
parties to consummate the Merger are satisfied or waived (as permitted), the
Merger will be consummated and effected on the date and at the time a
Certificate of Merger, reflecting the Merger, is filed with the Secretary of
State of the State of Georgia (the "Effective Time").  Unless otherwise mutually
agreed upon in writing by the chief 

                                       17
<PAGE>
 
executive officers of each of CSBI and BCG, CSBI and BCG have agreed to use
their reasonable efforts to cause the Effective Time to occur on the last
business day of the month in which occurs the last to occur of (i) the effective
date (including expiration of any applicable waiting period) of the last
required consent of any regulatory authority having authority over and approving
or exempting the Merger, and (ii) the date on which the shareholders of BCG
approve the Merger Agreement or such later date as may be mutually agreed upon
in writing by the chief executive officers of CSBI and BCG. Assuming
satisfaction of all conditions to consummation of the Merger, the Merger is
expected to be made effective during the fourth quarter of 1997. Either CSBI or
BCG may terminate the Merger Agreement if the Merger has not been consummated by
December 31, 1997. See "Conditions to Consummation" and "Amendment, Waiver, and
Termination."

DISTRIBUTION OF CSBI CERTIFICATES

     Promptly after the Effective Time, CSBI shall mail appropriate transmittal
materials to each record holder of BCG Common Stock for use in effecting the
surrender and cancellation of those certificates in exchange for CSBI Common
Stock (which shall contain an affidavit for lost or stolen stock certificates
and which shall specify that delivery shall be effected, and risk of loss and
title to the certificates theretofore representing shares of BCG Common Stock
shall pass, only upon proper delivery of such certificates to CSBI by the former
shareholders of BCG).  BCG SHAREHOLDERS SHOULD NOT SURRENDER THEIR CERTIFICATES
FOR EXCHANGE UNTIL THEY RECEIVE SUCH LETTER OF TRANSMITTAL AND INSTRUCTIONS.
After the Effective Time, each holder of shares of BCG Common Stock issued and
outstanding at the Effective Time shall surrender the certificate or
certificates representing such shares to CSBI, and the certificates thus
surrendered will be canceled.  Unless otherwise designated by a BCG shareholder
on the transmittal letter, certificates representing shares of CSBI Common Stock
issued to BCG shareholders in connection with the Merger will be issued and
delivered to the tendering BCG shareholder at the address on record with the BCG
Common Stock transfer agent.  CSBI shall not be obligated to deliver the
consideration to which any former holder of BCG Common Stock is entitled until
such holder surrenders such holder's certificate or certificates representing
such holder's shares for exchange.  The certificate or certificates so
surrendered shall be duly endorsed as CSBI may require.  No party shall be
liable to a holder of BCG Common Stock for any property delivered in good faith
to a public official pursuant to any applicable abandoned property law.

     After the Effective Time, holders of certificates will have no rights with
respect to the shares of BCG Common Stock represented thereby other than the
right to surrender such certificates and receive in exchange therefor the shares
of CSBI Common Stock, if any, to which such holders are entitled, as described
above.  In addition, no dividend or other distribution payable to holders of
record of CSBI Common Stock will be paid to the holder of any BCG certificates
until such holder surrenders such certificates for exchange as instructed.
Subject to applicable law, upon surrender of the certificates, such holder will
receive the certificates representing the shares of CSBI Common Stock issuable
upon the exchange or conversion of such shares of BCG Common Stock, all withheld
dividends or other distributions (without interest), and any withheld cash
payments (without interest) to which such shareholder is entitled.

     If any certificate for CSBI Common Stock is to be issued in a name other
than that in which BCG certificate surrendered for exchange is issued, the BCG
certificate so surrendered shall be properly endorsed and otherwise in proper
form for transfer, and the person requesting such exchange shall affix any
requisite stock transfer tax stamps to the certificates surrendered, shall
provide funds for their purchase, or shall establish to the exchange agent's
satisfaction that such taxes are not payable.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a discussion of the material federal income tax
consequences of the Merger.  This discussion is based on the provisions of the
Code, the United States Department of the Treasury Regulations thereunder and
rulings and court decisions as of the date hereof, all of which are subject to
change, possibly retroactively.  The discussion applies only to BCG
shareholders, if any, who hold their stock as a capital asset.  CSBI and BCG
have not requested a ruling from the Internal Revenue Service (the "Service").
A condition to consummation of the Merger is the receipt by each of CSBI and BCG
of an opinion of Troutman Sanders LLP, counsel to CSBI, as to the qualification
of the Merger as a tax-free reorganization and certain other federal income tax
consequences of the Merger. The opinion will be delivered by Troutman Sanders
LLP upon closing of the 

                                       18
<PAGE>
 
Merger in the form which has been included as an Exhibit to the Registration
Statement regarding this Proxy Statement/Prospectus.

     The Merger is intended to be a tax-free reorganization within the meaning
of section 368 (a) of the Code.  Among other things, the following discussion is
based on BCG shareholders maintaining sufficient equity ownership interest in
CSBI after the Merger.  The Service takes the position for purposes of issuing
an advance ruling on reorganizations, that the shareholders of an acquired
corporation (i.e., BCG) must maintain a continuing equity ownership interest in
the acquiring corporation (i.e., CSBI) equal, in terms of value, to at least 50%
of their interest in such acquired corporation.  For this purpose, shares of BCG
Common Stock exchanged for cash in lieu of any fractional shares of CSBI Common
Stock will be treated as outstanding shares of BCG Common Stock at the Effective
Time.  Moreover, shares of BCG Common Stock and CSBI Common Stock held by BCG
shareholders and otherwise sold, redeemed or disposed of prior or subsequent to
such time are taken into account.  Management of CSBI has no plan or intention
to cause CSBI to redeem or otherwise reacquire the shares of CSBI Common Stock
issued in the Merger.  In addition to the foregoing requirements certain
additional matters must be true with respect to the Merger.  CSBI believes that
these additional factual matters will be satisfied.

     Assuming the Merger is treated as a reorganization as defined in section
368(a) of the Code, the following should be certain federal income tax
consequences to BCG shareholders:

     (i) No gain or loss will be recognized for federal income tax purposes by
BCG shareholders upon the exchange of their shares of BCG Common Stock for CSBI
Common Stock;

     (ii) The basis of the shares of CSBI Common Stock to be received by BCG
shareholders will be the same as the basis of BCG Common Stock surrendered in
exchange therefor;

     (iii)  The holding period of CSBI Common Stock to be received by BCG
shareholders will include the period during which the shares of BCG Common Stock
surrendered in exchange therefor had been held, provided such shares were held
by such shareholders as a capital asset at the Effective Time; and

     (iv) The payment of cash in lieu of fractional shares of CSBI Common Stock
will be treated as if the fractional shares were issued as part of the exchange
and then redeemed by CSBI.  These cash payments will be treated as having been
received as distributions in full payment in exchange for the fractional shares
of CSBI Common Stock redeemed as provided in section 302(a) of the Code.
Generally, any gain or loss recognized upon such exchange will be capital gain
or loss, provided the fractional share would constitute a capital asset in the
hands of the exchanging shareholder.

     BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE
PARTICULAR CIRCUMSTANCES OF EACH SHAREHOLDER AND OTHER FACTORS, EACH HOLDER OF
BCG COMMON STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISER TO DETERMINE
THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE
APPLICATION AND EFFECT OF STATE AND LOCAL INCOME AND OTHER TAX LAWS).

MANAGEMENT AND OPERATIONS AFTER THE MERGER

     CSBI Directors. At the Effective Time, BCG will be merged into CSBI and the
BCG Banks will become wholly-owned subsidiaries of CSBI.  CSBI and the BCG Banks
will continue to be governed by the laws of the State of Georgia and the United
States and operate in accordance with their respective Articles of
Incorporation, Articles of Association, and Bylaws as in effect on the date of
the Merger Agreement until otherwise amended or repealed after the Effective
Time.  CSBI intends to operate the  BCG Banks as  wholly-owned subsidiaries of
CSBI following the Effective Time.  Following the consummation of the Merger,
CSBI shall have 11 directors determined as follows:

          (a) Immediately before the Effective Time all but five directors of
CSBI will resign as directors of CSBI;

                                       19
<PAGE>
 
          (b) Three of the resulting vacancies on the Board of Directors of CSBI
will be filled by those  three nominees designated by the president of BCG; and

          (c) The remaining three vacancies on the Board of Directors of CSBI
shall be selected by majority vote of the eight directors then serving on the
CSBI Board of Directors.

     CSBI Officers. The officers of CSBI in office immediately prior to the
Effective Time shall serve as the officers of CSBI from and after the Effective
Time in accordance with the Bylaws of CSBI except the officers who shall serve
in the offices and capacities as follows:

          (a) William H. Anderson, II, Chairman;

          (b) J. Russell Ivie, Vice-Chairman;

          (c) James A. Faulkner, Vice-Chairman and Chief Executive Officer; and

          (d) Joseph W. Evans, President, Chief Operating Officer and Chief
Financial Officer.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     As of August __, 1997, the directors and executive officers of BCG  owned
1,015 shares of CSBI Common Stock.  Other than as described herein, no director
or executive officer of CSBI or BCG, and no associate of any such person, has
any substantial interest, direct or indirect, in the Merger, other than an
interest arising from the ownership of BCG Common Stock, in which case the
director or officer receives no extra or special benefit not shared on a pro
rata basis by all other holders of BCG Common Stock.

     Certain members of BCG's management and Board of Directors may be deemed to
have interests in the Merger in addition to their interests as shareholders of
BCG generally.  In each case, the Board of Directors of BCG either was aware of
these factors or, with respect to interests that arose subsequent to the Merger
Agreement, was aware of their potential, and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby.

     The Merger Agreement provides that, after the Effective Time, CSBI will
provide generally to officers and employees of BCG, employee benefits under
employee benefit plans, on terms and conditions that, when taken as a whole, are
substantially similar to those currently provided by CSBI and its subsidiaries
to their similarly situated officers and employees.  For purposes of
participation and vesting (but not benefit accrual) under such employee benefit
plans, service with BCG prior to the Effective Time will be treated as service
with CSBI or its subsidiaries.  The Merger Agreement also provides that CSBI
will honor all employment, severance, consulting and other compensation
contracts previously disclosed to CSBI between BCG and any current or former
director, officer or employee, and all provisions for vested amounts earned or
accrued through the Effective Time under BCG's benefit plans. Each Party will
exercise its best efforts to amend any agreement it has with its respective
officers and employees to except the Merger from qualifying under any change of
control provision under such officers or employee's employment or similar
agreement. In the event the Parties are unsuccessful in modifying such
agreements containing change of control provisions, the parties estimate that
the maximum aggregate payments to those employees would be approximately $ -0-
                                                                          ----
for BCG and $1,525,813 for CSBI.
 
     At the Effective Time, all rights with respect to BCG Common Stock pursuant
to stock options granted by BCG under the BCG Key Employee Stock Option Plan
("BCG Option Plan"), which are outstanding at the Effective Time, whether or not
then exercisable, will be converted into and become rights with respect to CSBI
Common Stock, and CSBI will assume each BCG stock option, in accordance with the
terms of the BCG Option Plan under which it was issued and the stock option
agreement by which it is evidenced. From and after the Effective Time; (i) each
BCG stock option assumed by CSBI may be exercised solely for shares of CSBI
Common Stock; (ii) the number of shares of CSBI Common Stock subject to such BCG
stock option will be equal to the number of shares of BCG Common Stock subject
to such BCG option immediately prior to the Effective Time multiplied by 1.35;

                                       20
<PAGE>
 
(iii) the per share exercise price under each such BCG stock option will be
adjusted by dividing the per share exercise price under each such BCG stock
option by 1.35. In addition, each BCG stock option will, in accordance with its
terms, be subject to further adjustment as appropriate to reflect any stock
split, stock dividend, recapitalization or other similar transaction subsequent
to the Effective Time.

CONDITIONS TO CONSUMMATION

     The obligations of BCG and CSBI to consummate the Merger are subject to the
satisfaction or waiver (to the extent permitted) of the following conditions:
(i) the Merger, the Merger Agreement and all other documents and instruments to
be delivered in connection therewith shall have been approved by the Boards of
Directors of BCG and CSBI and by the shareholders of BCG; (ii) the required
regulatory approvals described under "Regulatory Approvals" shall have been
received, generally without any conditions or requirements which would, in the
reasonable judgment of the Board of Directors of either CSBI or BCG, materially
adversely affect the economic or business benefits of the transactions
contemplated by the Merger Agreement so as to render inadvisable the
consummation of the Merger, (iii) each party shall have received any required
consents of third parties; (iv) the Registration Statement of which this Proxy
Statement/Prospectus is a part shall have been declared effective by the
Commission and shall not be subject to a stop order or any threatened stop

under the securities laws of the various states in which such qualification,
registration or approval is required; (v) CSBI and BCG shall have received an
opinion of Troutman Sanders LLP as to certain tax matters;  (vi) the other
party's representations and warranties shall remain accurate, and the other
party shall have performed all of the agreements, covenants, acts and
undertakings to be performed by it pursuant to the Merger Agreement, and shall
have delivered certificates confirming satisfaction of the foregoing
requirements; (vii) each party shall have received an opinion of the other
party's counsel, dated the closing date, as to certain matters; (viii) CSBI and
BCG shall have received a letter from KPMG Peat Marwick LLP to the effect that
the Merger will qualify for pooling-of-interests accounting treatment; (ix) CSBI
shall have received a letter from each affiliate of BCG to the extent necessary

(xi) each party shall have completed a due diligence investigation in regard to
the other party to its sole satisfaction. The tax opinion will be delivered by
Troutman Sanders LLP, upon closing of the Merger in the form which has been
included as an Exhibit to the Registration Statement regarding this Proxy
Statement/Prospectus.

     No assurances 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 appropriate
party.  As of the date of this Proxy Statement/Prospectus, the parties know of
no reason to believe that any of the conditions set forth above will not be
satisfied.

     The conditions to consummation of the Merger may be waived, in whole or in
part, to the extent permissible under applicable law, by the party for whose
benefit the condition has been imposed, without the approval of the BCG
shareholders.  See "Amendment, Waiver, and Termination."

REGULATORY APPROVALS

     The Merger is subject to the prior approval of the Federal Reserve under
the BHC Act, and the DBF under the Financial Institutions Code of Georgia (the
"FICG").  On July 15, 1997, the DBF approved CSBI's application to acquire BCG
subject to BCG shareholder approval and the maintenance of BCG Banks' capital
adequacy by CSBI after the consummation of the Merger. On July 11, 1997, the
Federal Reserve approved CSBI's application to acquire BCG.  The Merger may not
be consummated before the fifteenth day following the approval of the Merger by
the Federal Reserve, during which time the United States Department of Justice
and other interested parties have the opportunity to file suit seeking to enjoin
consummation of the Merger on antitrust grounds.

AMENDMENT, WAIVER, AND TERMINATION

     To the extent permitted by law, BCG and CSBI, with the approval of their
respective Boards of Directors, may amend the Merger Agreement by written
agreement at any time without the approval of the shareholders of 

                                       21
<PAGE>
 
BCG, provided that after the approval of the Merger by BCG's shareholders, no
amendment may decrease the consideration to be received by BCG shareholders
without the requisite approval of BCG shareholders.

     Prior to or at the Effective Time, either CSBI or BCG, acting through its
respective Board of Directors, chief executive officer or other authorized
officer, may waive any default in the performance of any term of the Merger
Agreement by the other party, may waive or extend the time for the fulfillment
by the other party of any of its obligations under the Merger Agreement, and may
waive any of the conditions precedent to the obligations of such party under the
Merger Agreement, except any condition that, if not satisfied, would result in
the violation of an applicable law or governmental regulation.

     The Merger Agreement may be terminated, and the Merger abandoned, at any
time prior to the Effective Time by mutual consent of the Boards of Directors of
CSBI and BCG.  In addition, the Merger Agreement may be terminated, and the
Merger abandoned, prior to the Effective Time by either CSBI or BCG if (i) the
other party breaches and does not timely cure any representation, warranty,
covenant or other agreement contained in the Merger Agreement and such breach,
individually or in the aggregate, has a "Material Adverse Effect" (as defined in
the Merger Agreement) on the non-breaching party, (ii) any consent or approval
of certain regulatory authorities is denied by final nonappealable action of
such authority, (iii) the Merger has not been consummated by December 31, 1997,
or by either party in the event that the Board of Directors of the other party
shall have failed to reaffirm, following a written request by such party for
such reaffirmation after either party shall have received any inquiry or
proposal with respect to an "Acquisition Proposal" (as defined in the Merger
Agreement), its approval of the Merger and the transactions contemplated by this
Agreement (to the exclusion of any other Acquisition Proposal), or shall have
resolved not to reaffirm the Merger.  See "Expenses and Fees."

CONDUCT OF BUSINESS PENDING THE MERGER

     Each party generally has agreed in the Merger Agreement, unless the prior
consent of the other party is obtained, and except as otherwise contemplated by
the Merger Agreement, to operate their respective businesses only in the
ordinary course, to preserve their respective businesses and assets and to
maintain their respective rights and franchises and to take no action that would
adversely affect either the ability of either party to perform such party's
covenants and agreements under the Merger Agreement or the ability of either
party to obtain any consents or approvals pursuant to any contract, law, order
or permit that are required for the transactions contemplated by the Merger
Agreement.  In addition, the Merger Agreement contains certain other
restrictions applicable to the conduct of the business of each party prior to
consummation of the Merger, as described below.

     Each party has agreed in the Merger Agreement not to take certain actions
relating to the operation of their respective businesses pending consummation of
the Merger without the prior approval of the other party.  Those actions
generally include, without limitation: (i) amending its Articles or Bylaws; (ii)
becoming responsible for any obligation for borrowed money in excess of an
aggregate of $100,000, except in the ordinary course of their respective
businesses consistent with past practices; (iii) acquiring or exchanging any

     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, to provide
information to any party making such a proposal or to enter into any agreement
with regard to any such proposal except in compliance with its legal obligations
or the fiduciary obligations of its Board of Directors. The parties have also
agreed to use reasonable efforts to cause their respective advisors and other
representatives not to engage in any of the foregoing activities.

EXPENSES AND FEES

     The Merger Agreement provides that each party shall be responsible for its
own costs and expenses incurred in connection with the negotiation and
consummation of the transactions contemplated by the Merger Agreement.  In
addition, if within 12 months following the termination of the Merger Agreement
or the failure to consummate the Merger by reason of any failure of either party
to satisfy certain conditions, any third party acquires, merges with, combines
with, or purchases a significant amount of the assets of, or purchases 20% or
more of any equity security of, such party ("Business Combination"), then such
third party will be required to pay all of the other party's direct costs and
expenses relating to the Merger and an additional sum equal to $500,000.

ACCOUNTING TREATMENT

     The Merger is anticipated to be accounted for on a pooling-of-interests
accounting basis.  Under this method of accounting, as of the Effective Time,
the assets and liabilities of BCG would be added to those of CSBI at their
recorded book values and the shareholders' equity accounts of CSBI and BCG would
be combined on CSBI's consolidated balance sheet.  The unaudited pro forma
financial information contained in this Proxy Statement/Prospectus has been
prepared using the pooling-of-interests accounting method to account for the
Merger.  See "SUMMARY" and "PRO FORMA COMBINED FINANCIAL DATA."

RESALES OF CSBI COMMON STOCK

     The shares of CSBI Common Stock issued in connection with the Merger will
be freely transferable under the Securities Act, except for shares issued to any
shareholder who may be deemed to be an "affiliate" (generally including, without
limitation, directors, certain executive officers, and beneficial owners of 10%
or more of any class of capital stock) of BCG for purposes of Rule 145 under the
Securities Act as of the date of the Special Meeting or for purposes of
applicable interpretations regarding pooling-of-interests accounting treatment.
Such affiliates may not sell their shares of CSBI Common Stock acquired in
connection with the Merger except pursuant to an effective registration
statement under the Securities Act or an applicable exemption from the
registration requirements of the Securities Act and until such time as financial
results covering at least 30 days of combined operations of CSBI and BCG after
the consummation of the Merger have been published.  CSBI will place restrictive
legends on certificates representing CSBI Common Stock issued to all persons who
are deemed to be "affiliates" of BCG under Rule 145.  In addition, BCG has
agreed to use its reasonable efforts to cause each person or entity that is an
"affiliate" to enter into a written agreement in substantially the form attached
to the Merger Agreement relating to such restrictions on sale or other transfer.
This Proxy Statement/Prospectus does not cover resales of CSBI Common Stock
received by any person who may be deemed to be an affiliate of BCG.

                               DESCRIPTION OF BCG

GENERAL

     BCG is a bank holding company operating two community banks in Georgia.
BCG was incorporated under the laws of Georgia in 1980 and commenced operations
that year by acquiring 100% of the outstanding shares of Bank of Fort Valley.
All of BCG's activities are currently conducted by its wholly-owned community
banking subsidiaries, First South  Bank, National Association, Macon, Georgia
("FSB"), and Ameribank, National Association, Savannah, Georgia ("Ameribank")
(FSB and Ameribank are sometimes referred to herein collectively as the "BCG
Banks" and each individually as a "BCG Bank").  During 1996, First South Bank of
Middle Georgia, National Association, Macon, Georgia and First South Bank of
Coweta County, National Association, Newnan Georgia were merged with FSB, and
FSB changed the address of its principal office to 4961 Forsyth Road, Macon,
Georgia  31210.

Employees

     As of March 19, 1997, the BCG Banks had an aggregate of 155 full-time
equivalent employees and BCG had a total of 10 full-time equivalent employees.
Neither BCG, nor any of the BCG Banks is a party to any collective bargaining
agreement, and BCG and the BCG Banks believe that their employee relations are
good.

PROPERTIES

     FSB's main office is located at 4961 Forsyth Road, Macon, Georgia adjacent
to BCG's headquarters and operations center located at 4951 Forsyth Road, Macon,
Georgia.  Ameribank's main office is located at 7394 Hodgson Memorial Drive,
Savannah, Georgia.  Each BCG Bank owns its main office.  FSB leases its loan
operations office space from William H. Anderson, II, Chairman of the BCG Board
of Directors.  In addition, FSB leases from Mr. Anderson the space in which the
BCG Corporate office and the FSB operations center are located.  See "CERTAIN
RELATIONSHIPS AND RELATED TRANSACTIONS."  During 1996, Ameribank entered into a
sublease agreement for the Ameribank downtown Savannah location.  This agreement
was entered into in conjunction with Ameribank's acquisition of a Bank South
(now NationsBank) facility.  FSB operates one branch in each of Peach, Macon,
Johnson, Bibb and Coweta counties.  Ameribank operates three branches, one,
acquired from Bank South (now NationsBank) in 1996, in Savannah, Georgia, one in
downtown Savannah, opened in 1996 and one in Rincon, Georgia, acquired through
BCG's acquisition of Effingham Bank & Trust in 1996.  Effective December 1,
1996, Ameribank closed its Garden City, Georgia branch.

COMPETITION

     The banking business is highly competitive.  FSB competes with two other
banks in Peach County, two other banks in Macon County, one other bank in
Johnson County, eight other banks in Bibb County, and five other banks in Coweta
County.  Ameribank competes with ten other banks in Chatham County and two other
banks in Effingham County.  The BCG Banks also compete with other financial
service organizations, including thrifts, finance companies, credit unions and
certain governmental agencies. To the extent that the BCG Banks must maintain
non-interest-earning reserves against deposits, they may be at a competitive
disadvantage when compared with other financial service organizations that are
not required to maintain reserves against substantially equivalent sources of
funds.

Dividends

     During 1996, BCG paid one cash dividend of $.10 per share to its
shareholders of record as of September 5, 1996.  In March 1995, BCG paid one 75%
BCG Common Stock dividend to its shareholders.  Also in 1995, BCG paid one cash
dividend of $.10 per share of BCG Common Stock to its shareholders of record as
of September 15, 1995.  Although BCG intends to continue paying cash dividends,
the amount and frequency of cash dividends will be determined by BCG's Board of
Directors after consideration of earnings, capital requirements and 

                                       31
<PAGE>
 
the financial condition of BCG. No assurances can be given that cash dividends
will be declared in the future. Additionally, BCG's ability to pay cash
dividends will be dependent on cash dividends paid to it by the BCG Banks. The
ability of the BCG Banks to pay dividends to BCG is restricted by applicable
regulatory requirements.

ACQUISITIONS

     On March 26, 1996,  AmeriCorp, Inc. ("AmeriCorp"), a Georgia corporation
and which held 100% of the common stock of Ameribank, was merged with and into
BCG.  The holders of common stock of AmeriCorp (other than BCG)  received
 .084615 shares of BCG Common Stock for each of their shares of AmeriCorp common
stock.  Prior to the AmeriCorp Merger, BCG owned 66 2/3% of the AmeriCorp common
stock and 100% of the AmeriCorp preferred stock.

     On February 9, 1996, Ameribank purchased certain assets, including
approximately $3.3 million in loans, and assumed certain liabilities, including
approximately $16.7 million in deposit liabilities, related to the banking
office of Bank South (now NationsBank) located at 1976 East Victory Drive in
Savannah, Georgia pursuant to a Branch Purchase and Assumption Agreement dated
October 18, 1995.   Bank South (now NationsBank) also assigned the lease of the
former Bank South Center located at 7 East Congress Street, Savannah, Georgia to
Ameribank.  Ameribank did not assume any of the deposits or other liabilities
related to the East Congress Street facility.

     On June 6, 1996, BCG acquired Effingham Bank & Trust ("Effingham"), a full
service Georgia state chartered bank with one office in Rincon, Effingham
County, Georgia with approximately $25,000,000 in assets.  The holders of
Effingham Common stock received .59 shares of BCG $1 par value common stock for
each share of common stock held by them for an aggregate of 204,928 shares of
BCG Common Stock.  On October 1, 1996, Effingham was merged into Ameribank.

     In March 1994, FSB sold substantially all of the assets and liabilities of
its Ashburn, Georgia branch to Ashburn Bank.  In connection with the sale, FSB
transferred deposit liabilities totaling approximately $7,369,000 and assets,
consisting primarily of loans, of $4,787,000 and cash of approximately
$2,404,000.  FSB recognized a gain of approximately $178,000 from the sale
before income tax expense.  In September of 1994, BCG sold substantially all of
the assets and liabilities of First South Bank of Ben Hill County, Fitzgerald,
Georgia to Bankers First, FSB.  BCG transferred approximately $14,540,000 in
deposit liabilities and $3,791,000 in assets, primarily loans, and approximately
$10,114,000 in cash to Bankers First, FSB.  The gain on the sale of the First
South Bank of Ben Hill County assets and liabilities amounted to approximately
$636,000 before related income tax expense.

SERVICES

     The BCG Banks are community-oriented, with an emphasis on lending to small
businesses and professionals and providing other customary banking services,
such as consumer and commercial checking accounts, NOW accounts, savings
accounts, certificates of deposit, lines of credit, Mastercard and VISA accounts
and money transfers.  The BCG Banks finance commercial and consumer
transactions, make secured and unsecured loans, including residential mortgage
loans, and provide a variety of other banking services.

MARKETS

     The primary markets for FSB are Bibb, Coweta, Johnson, Macon and Peach
Counties, Georgia.  The primary markets for Ameribank are Effingham and Chatham
Counties, Georgia.

DEPOSITS

     The BCG Banks offer a full range of depository accounts and services to
both consumers and businesses.  At December 31, 1996, the BCG Banks' deposit
base, totaling approximately $258.7 million, consisted of approximately $44.7
million in non-interest-bearing demand deposits (17.3% of total deposits),
approximately $79.4 million in interest-bearing demand deposits (including money
market accounts) (30.7% of total deposits), approximately $9.4 million in
savings deposits (3.6% of total deposits), approximately $96.1 million in time

                                       32
<PAGE>
 
deposits in amounts less than $100,000 (37.1% of total deposits), and
approximately $29.1 million in time deposits of $100,000 or more (11.3% of total
deposits).

LOANS

     The BCG Banks make both secured and unsecured loans to individuals, firms
and corporations, and both consumer and commercial lending operations include
various types of credit for their customers.  Secured loans include first and
second real estate mortgage loans.  The BCG Banks also make direct installment
loans to consumers on both a secured and unsecured basis.  At December 31, 1996,
consumer, real estate (including mortgage and construction loans) and commercial
loans represented approximately 6.0%, 70.6%, and 23.4%, respectively, of the BCG
Banks' total loan portfolio.  The BCG Banks make a variety of real estate loans,
including loans for residential real estate construction, acquisition and
development loans, as well as loans for other purposes that are secured by real
estate.

     Specific risk elements associated with each of the BCG Banks' lending
categories are as follows:

Commercial, financial
 and agricultural                  Industry concentrations, inability to monitor
                                   the condition of collateral (inventory,
                                   accounts receivable and vehicles), lack of
                                   borrower management expertise, increased
                                   competition, and specialized or obsolete
                                   equipment as collateral

Real estate - construction         Inadequate collateral and long-term financing
                                   agreements

Real estate - mortgage             Changes in local economy and caps on
                                   variable rate loans

Installment loans to individuals   Loss of borrower's employment, changes in 
                                   local economy, the inability to monitor 
                                   collateral (vehicle, boats and mobile homes)

LENDING POLICY

     The current lending strategy of each of the BCG Banks is to offer consumer,
real estate and commercial credit services to individuals and entities that meet
the particular BCG Bank's credit standards.  Each BCG Bank provides its lending
officers with written guidelines for lending activities.  Lending authority is
delegated by the Board of Directors of the particular BCG Bank to loan officers,
each of whom is limited in the amount of secured and unsecured loans which he or
she can make to a single borrower or related group of borrowers.

LOAN REVIEW AND NON-PERFORMING ASSETS

     BCG reviews each of the BCG Bank's portfolio to determine deficiencies and
corrective action to be taken.  Periodic reviews are conducted of borrowers with
total direct and indirect indebtedness of $100,000 or more and of all past-due
loans.  Past-due loans are reviewed at least monthly by lending officers and a
summary report is reviewed monthly by senior management and quarterly by the
particular BCG Bank's Board of Directors.  The loan review function periodically
reviews all relationships over $100,000, whether current or past due. The loan
review function reviews significant findings with the Board quarterly.  In
addition, each BCG Bank maintains internal classifications of problem and
potential problem loans.

ASSET/LIABILITY MANAGEMENT

     Each BCG Bank's Board of Directors is charged with establishing policies to
manage the assets and liabilities of the particular BCG Bank.  Each Board's task
is to manage asset growth, net interest margin, liquidity and capital.  The
Board directs the BCG Bank's overall acquisition and allocation of funds.  On a
quarterly basis, the Board of each BCG Bank receives a report with regard to the
monthly asset and liability funds budget and income 

                                       33
<PAGE>
 
and expense budget in relation to the actual composition and flow of funds, the
ratio of the amount of rate-sensitive assets to the amount of rate-sensitive
liabilities, the ratio of loan loss reserves to outstanding loans, and other
variables, such as expected loan demand, investment opportunities, core deposit
growth within specified categories, regulatory changes, monetary policy
adjustments and the overall condition of the local, state and national economy.

INVESTMENT POLICY

     Each BCG Bank's investment portfolio policy is to maximize income
consistent with liquidity, asset quality and regulatory constraints.  The policy
is reviewed from time to time by the particular BCG Bank's Board of Directors.
Individual transactions, portfolio composition and performance are reviewed and
approved by the particular BCG Bank's Board of Directors or a committee thereof.
The Treasurer of each BCG Bank implements the policy and reports to the BCG
Bank's full Board of Directors on a quarterly basis information concerning
sales, purchases, resultant gains or losses, average maturity, federal taxable
equivalent yields, and appreciation or depreciation by investment categories.

     In general, the BCG Banks' investment policy is to place all securities in
the Available for Sale portfolio upon purchase.  As of December 31, 1996,
substantially all of the BCG Banks' securities were in the Available for Sale
security portfolio.

     At December 31, 1996, a substantial portion of the BCG Banks' securities
consisted of single maturity, fixed-rate U.S. Treasury and Agency securities
with a weighted average maturity of the portfolio of less than five years.  Also
included in the available for sale portfolio are certain mortgage-backed
securities which were purchased by FSB in 1996 and  acquired when BCG acquired
Effingham. The primary risks in the BCG Banks' securities portfolio consist of:

       Credit risk, or the risk of default of the issuer. Substantially all of
       the securities are in Treasury and Agency securities; therefore, the
       credit risk is primarily limited to the risk of default of the U.S.
       Government and its agencies.

       Interest rate risk, or the risk of adverse movements in interest rates on
       the value of the portfolio.  In general, a rise in interest rates will
       cause the value of the BCG Banks' securities to decline.  The longer the
       maturity of an individual security, the greater the effect of a change in
       interest rates on its value.


CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     The BCG Banks have had, and expect to have in the future, banking
transactions in the ordinary course of business with directors and officers of
BCG and the BCG Banks and their associates, including corporations in which such
officers or directors are shareholders, directors and/or officers, on the same
terms (including interest rates and collateral) as those prevailing at the time
for comparable transactions with other persons.  Such transactions have not
involved more than the normal risk of collectibility or presented other
unfavorable features.  At December 31, 1996, loans to directors and officers and
their associates totaled $6,878,000, or 25.74% of total shareholders' equity.

     On November 16, 1988, FSB entered into a lease agreement, as amended on
March 12, 1992 (the "Lease"), with William H. Anderson, II, Chairman of the
Board of Directors of BCG, pursuant to which Mr. Anderson rents to FSB the
office at which the FSB operations center, FSB loan servicing office and BCG's
executive offices are located.  The initial term of the Lease expired on January
31, 1996, and at that time the term of the Lease was extended to January 31,
2004.  Currently, Mr. Anderson receives monthly rental payments of $6,710.84.
During the 1996 fiscal year, rental payments by FSB totaled approximately
$82,000 under the Lease.

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

                  Years ended December 31, 1996, 1995 and 1994



     This analysis has been prepared to provide insight into the consolidated
financial condition of BCG and addresses the factors which have affected BCG's
results of operations.  Unless otherwise noted, the financial and other
information presented with respect to BCG in this discussion and elsewhere in
this Proxy Statement/Prospectus generally includes the accounts of the BCG
Banks.  BCG's consolidated financial statements and accompanying notes which
follow are an integral part of this review and should be read in conjunction
with it.

     GENERAL OVERVIEW OF BCG.  Net income for 1996 was $3,312,690 as compared to
$2,863,658 for 1995. Pretax earnings increased $342,000 over 1995 primarily due
to an increase in net interest income of $1,305,000, a decrease in the provision
for loan losses of $56,000, an increase in other income of $701,000, offset by
increases in salaries and employee benefits of $460,000 and increases in other
operating expenses of $1,007,000.

     The following table sets out certain ratios of BCG for the years indicated:

  Average stockholders' equity       13.52%      13.75%       13.33%

Average equity to average assets      8.62%       8.51%        7.63%
</TABLE>

     ASSET QUALITY.  The allowance for loan losses represents an amount which,
in management's judgement, will be adequate to absorb losses on existing loans
that may become uncollectible.  The adequacy of the allowance for loan losses is
evaluated monthly based on a regular review of the BCG Banks' loan portfolios,
with particular emphasis on non-accruing loans, past due loans, and other loans
that management believes require attention.

     There was a favorable trend in the amount of loans past due by 90 days or
more over the last year. The percentage of these past dues to the total loan
portfolio was .39% at December 31, 1996, as compared to .63% at December 31,
1995. The BCG Banks' levels of non-performing assets have decreased from
$1,468,000 at December 31, 1995 to $1,040,000 at December 31, 1996, primarily
due to reduction of non-accrual loans.  Non-performing assets are composed of
non-accrual loans (loans on which interest income is no longer being accrued),
and foreclosed assets (assets acquired in full or partial satisfaction of debt).

     As a result of management's ongoing review of the loan portfolio, loans are
classified as non-accruing when it is not reasonable to expect collection of
interest under the original terms. These loans may be classified as non-accruing
even though the presence of collateral or the borrower's financial strength may
be sufficient to provide for ultimate repayment of principal.

</TABLE>


     Loans past due on interest and/or principal payments have decreased in
dollar terms by $1,168,000 (39.8%) between year end 1995 and 1996. Commercial
and commercial real estate loans 90 days or more past due as to principal or
interest are transferred to non-accruing status unless fully secured by
collateral. In addition, loans past due less than 90 days, which in the opinion
of management present significant uncertainty as to collectability of interest,
are also placed on non-accrual status. Installment loans and credit lines are
charged off when losses become apparent, and in no event later than 120 days
after the date on which the balance became past due.

     The allowance represents an amount which, in management's judgement, will
be adequate to absorb losses on existing loans that may become uncollectible.
Management determines the allowance level and its allocation based upon its
judgment concerning factors affecting loan quality and its assumptions regarding
the economy. Based upon its extensive ongoing review of the loan portfolio,
management considers the 1996 year-end allowance for loan losses to be adequate
to cover potential losses in the BCG Banks' loan portfolio.

     The current levels of loans on non-accrual status and the portfolio of
other real estate owned impacts earnings as interest is not earned and
additional costs are incurred in the disposition of these assets.  In order to
manage the non-performing assets, management of the BCG Banks has established
specific goals for the resolution of all loans on non-accrual status and all
other real estate owned.

     EARNING ASSETS.  In 1996, earning assets averaged $252.7 million, a 12.7%
increase from $224.2 million in 1995.  The increase of $28.5 million is
comprised mainly of a $22.0 million increase in average loans, and an $8.3
million increase in average federal funds sold offset by a $3.2 million decrease
in interest bearing deposits in banks.

     LOANS.  Loans are the single-largest component of earning assets, as well
as the highest yielding component.  Because of their importance, most other
assets and liabilities are managed to accommodate the needs of the loan
portfolio.  At December 31, 1996 and 1995, loans represented 73.4% and 76.6% of
interest- earning assets and 64.3% and 68.5%, respectively, of total assets.
Net loans increased $8,694,095, or 4.89% in 1996, compared to an increase of
13.32% in 1995.

     BCG's primary emphasis in terms of lending is on commercial business loans,
as it attempts to define its market niche and decrease its credit risk exposure.
From a marketing perspective, the BCG Banks believe that the credit needs of
small business owners are often not handled effectively by smaller banks and are
not attractive to larger banks which typically pursue larger credits. This
provides an opportunity to the BCG Banks within their markets. From a
perspective of credit risk reduction, the BCG Banks' credit standards require
that prospective commercial borrower's provide a high probability of adequate
cash flow for debt service, as well as commercial real estate collateral and
personal guarantees providing secondary loss protection for the BCG Banks.  In
connection with this increased emphasis on commercial, business, and real estate
lending, the BCG Banks increased their commercial, financial and agricultural
loan and real estate loan portfolios by $5,482,602 and $20,924,617 during 1996
and 1995, representing increases of 3.7% and 16.2%, respectively.

                                       39
<PAGE>
 
     INVESTMENTS.  BCG's investment portfolio constitutes the second-largest
component of total earning assets.  The portfolio serves several functions such
as providing a vehicle for the investment of available funds at relatively
attractive rates, furnishing liquidity to meet increased loan demand and
supplying securities to pledge as collateral for public funds.

     During 1996, holdings in investment securities increased $3,488,564 or
8.6%.  At December 31, 1996, investment securities represented 17.3% of
interest-earning assets as compared to 17.4% at December 31, 1995.  Securities
with a carrying value of approximately $18,433,000 were pledged as collateral
for public funds or other purposes as of December 31, 1996.

     Unrealized gains and losses, net of tax, are reported as a separate
component of shareholders' equity, in accordance with SFAS No.115. Unrealized
gains, net of tax, amounted to approximately $289,000 at December 31, 1996,
compared to unrealized gains, net of tax, of approximately $779,000 at December
31, 1995.

     DEPOSITS.  Total deposits increased by approximately $34,474,826 or 15.4%,
in 1996, compared to increases of $12,531,498 in 1995.

     Non-interest-bearing deposits constituted 17.3% of total deposits at
December 31, 1996 versus 16.8% at December 31, 1995.  The increase of $6,994,000
from 1995 to 1996 is the result of management's continued marketing efforts to
attract non-interest-bearing, fee-generating transaction accounts.

     INTEREST RATE SENSITIVITY.  Interest rate sensitivity management seeks to
maximize net interest income as a result of changing interest rates, but to do
so without subjecting the interest margin to an imprudent degree of risk.  BCG
attempts to do this by structuring the balance sheet so that repricing
opportunities exist for both assets and liabilities in roughly equivalent
amounts at approximately the same time intervals.  Imbalances in these repricing
opportunities at any point in time constitute a bank's interest rate
sensitivity.

     An indicator of the interest rate sensitivity structure of a financial
institution's balance sheet is the difference between its interest rate
sensitive assets and interest rate sensitive liabilities, which is referred to
as the "gap." BCG attempts to match the behavior of rate sensitive assets and
rate sensitive liabilities.  While "gap" analysis is a traditional indicator of
interest rate risk, management has observed that the historical behavior of
certain categories of assets and liabilities vary significantly from those
indicated by the "gap". Consequently, it relies more heavily on simulation
models as its primary interest rate management tool. Based upon its simulation
model, management believes that BCG is not subject to any material risk due to
interest rate fluctuations.

     The rate sensitivity table is a form of "gap" analysis.  A ratio of
interest earning assets to interest bearing liabilities (more interest earning
assets repricing in a given period than interest bearing liabilities) greater
than 100% suggests that an increase in interest rates have a positive effect and
a decrease in interest rates have a negative effect on net interest income. A
ratio less than 100% would have the opposite effect.

     Banking regulations currently prohibit the payment of interest on certain
types of demand deposits that are classified under the "gap" analysis as "rate
sensitive". To the extent that this regulation remains in effect, classifying
these deposits as "immediately rate sensitive" understates the benefit to the
net interest margin of rising rates and understates the detriment of falling
rates to the net interest margin.

     At December 31, 1996, BCG's interest rate sensitive liabilities maturing
within one year exceeded interest rate sensitive assets maturing within one year
by approximately $54.7 million with non-interest bearing demand deposits
classified as "immediately rate sensitive". This equates to a negative gap of
22% of earning assets which is identical to its position at December 31, 1995.
If non-interest bearing demand deposits were excluded from the "immediately rate
sensitive" category, the negative gap would be reduced to $10.0 million or 4% of
earning assets, compared to $11.1 million or 7% at December 31, 1995.

     Since interest rates and yields do not adjust at the same velocity, the
interest sensitivity gap is only an indicator of the potential effects of
interest rate changes on net interest income.

     LIQUIDITY.  Liquidity management involves the ability to meet cash flow
requirements of customers who may be depositors making withdrawals or borrowers
who require credit funding. BCG's cash flows are generated from interest and fee
income, as well as from loan repayments, deposit acquisition, and maturities or
sales of investments. BCG's liquidity needs are provided for primarily through
short-term securities, and the maturing of loans.  Federal funds sold, which
averaged approximately $13,943,000 in 1996, represent BCG's primary source of
immediate liquidity and are maintained at a level adequate to meet immediate
needs.  In addition, FSB has an agreement with the Federal Home Loan Bank
("FHLB") which provides additional liquidity. While BCG had no outstanding
advances from the FHLB at December 31, 1996, this agreement allows BCG to borrow
up to $22,000,000 secured by 1-4 single family residential mortgage loans.
Maturities in BCG's loan and investment portfolios are monitored regularly to
avoid matching short-term deposits with long-term loans and investments. Other
assets and liabilities are also monitored in an effort to provide the proper
balance between liquidity, safety and profitability.  This monitoring process
must be continuous due to the constant flow of cash which is inherent in a
financial institution.

     BCG manages its liquidity through changing deposit levels and patterns in
loan demand, its current liquidity position, its ability to control funding
needs and potential sources of funds. As part of managing liquidity, BCG
monitors its loan to deposit ratio on a daily basis.  The target ratio is 85%.
At December 31, 1996 and 1995 the ratio was 72.1% and 79.3%, respectively.

     BCG experienced an increase of $13,948,592 in cash and cash equivalents
during 1996. Operating activities provided $3,059,324, primarily through income
from operations of $3,312,690.

     Investing activities provides $715,938 in cash and cash equivalents.
Proceeds from calls, maturities, and sales within the securities portfolio
provided $16,771,760. These proceeds were offset by purchases of investment
securities of $21,021,208, and a net increase in loans of $5,952,803.  Also, BCG
received $12,687,620 in conjunction with the acquisition of certain assets and
liabilities of a banking unit.

     Financing activities provided $10,173,330 of cash and cash equivalents
during 1996 due mainly to the net increase in deposits of $17,783,870, offset by
the repayment of FHLB advances of $6,100,000.

     CAPITAL RESOURCES AND DIVIDENDS.  At December 31, 1996, BCG had capital in
excess of regulatory minimums, as measured by its ending equity to assets ratio
of 9.21%, compared to 8.56% at December 31, 1995.  The increase was primarily
the result of an increase in net earnings.

RESULTS OF OPERATIONS-1996 VERSUS 1995

     BCG's net income after minority interest in earnings of AmeriCorp for 1996
was $3,312,690 versus $2,863,658 for 1995, an increase of $449,032.  1996 income
was $1.41 per common share versus $1.35 per common share for 1995.

     Net interest income increased $1,305,052 or 9.8% from $13,251,895 in 1995
to $14,556,947 in 1996. The effect of volume changes was to increase net
interest income by $1,908,536, and the effect of rate changes was to decrease
net interest income by $603,484. Yields on interest earning assets decreased
from 10.08% in 1995 to 9.67% in 1996. The cost of interest bearing liabilities
decreased from 4.89% to 4.64% over the same period. The effect of these changes
was to decrease the net interest spread from 5.19% in 1995 to 5.03% in 1996.

     BCG is a party to interest rate swap agreements for the purpose of hedging
against short term decreases in interest rates.  The notional amount on
agreements outstanding at December 31, 1996 was $25,000,000.  The agreements
call for BCG to receive fixed rates of interest, averaging 6.32%, while paying
variable rates, based on the three month LIBOR.  Weighted average rates paid by
BCG during 1996 were approximately 5.53%. Reductions in interest expense of
$243,000 resulting from the difference in rates have been netted with interest
expense on time deposits.

     In addition BCG has purchased interest rate floor contracts with aggregate
notional amounts of $30,000,000, maturing in March 1997. Under the terms of the
agreement, BCG will be reimbursed on a quarterly basis for decreases in the
federal funds rate for any period during the agreement in which the federal
funds rate falls below 5.5%.  At December 31, 1996, the federal funds rate was
5.25%. Increases in interest income at $58,000 resulting from a drop in the
federal funds rate below 5.5% have been netted with interest and fees on loans.

     The provision for loan losses for 1996 was $409,000, compared to $465,005
for 1995.  Net charge-offs for 1995 were $129,000 compared to net charge-offs of
$212,000 during 1996.  The allowance for loan losses at December 31, 1996 and
1995 was $2,849,340 and $2,652,412, respectively. The allowance for loan losses
represented 1.50% and 1.46% of gross outstanding loans at December 31, 1996 and
1995, respectively.  Nonaccrual loans decreased from $978,000 at December 31,
1995 to $499,000 at December 31, 1996.

     Non-interest income increased by $700,915 or 29.6% from 1995 to 1996. This
increase was related to increases in service charge income of $208,773,
increases of $38,233 in gains on sale of loans, and increases in miscellaneous
other income of $444,639.

     Non-interest expense increased by $1,719,628 or 15.7% from 1995 to 1996.
Included in the change is increases in salaries and benefits of $459,480
increases in occupancy expense of $229,855, increases in equipment expense of
$22,901, and an increase in other operating expense of $1,007,392 resulting
primarily from the opening of several new branches during 1996.

     BCG recognized an income tax provision of $1,158,609 for 1996, compared to
a provision of $930,750 for 1995.  Reductions in the valuation allowance of
$551,956 and $439,294 were recognized in 1996 and 1995, respectively.

RESULTS OF OPERATIONS-1995 VERSUS 1994

     BCG's net income after minority interest in earnings of AmeriCorp for 1995
was $2,863,658 versus $2,309,280 for 1994, an increase of $544,378. 1995 income
was $1.35 per common share versus $1.11 per common share for 1994.

     Net interest income increased $2,629,335 or 24.8% from $10,622,560 in 1994
to $13,251,895 in 1995. The effect of volume changes was to increase net
interest income by $683,406, and the effect of rate changes was to increase net
interest income by $1,945,929. Yields on interest earning assets increased from
8.59% in 1994 to 10.08% in 1995. The cost of interest bearing liabilities
increased from 3.97% to 4.89% over the same period. The effect of these changes
was to increase the net interest margin to 5.19% in 1995 from 5.11% in 1994.

                                       43
<PAGE>
 
     During 1995, BCG entered into interest rate swap agreements for the purpose
of hedging against short term decreases in interest rates.  The notional amount
on agreements outstanding at December 31, 1995 was $15,000,000.  The agreements
call for BCG to receive fixed rates of interest, averaging 7.26%, while paying
variable rates, based on the three month LIBOR. Weighted average rates paid by
BCG during 1995 were approximately 5.5%.  Reductions in interest expense
resulting from the difference in rates of $160,000 have been netted with
interest expense on time deposits.

     The provision for loan losses for 1995 was $465,005, compared to $447,003
for 1994.  Net charge-offs for 1995 were $129,000 compared to net charge-offs of
$220,000 during 1994.  The allowance for loan losses at December 31, 1995 and
1994 was $2,652,412 and $2,316,054, respectively.  The allowance for loan losses
represented 1.46% and 1.48% of gross outstanding loans at December 31, 1995 and
1994, respectively. Nonaccrual loans increased from $529,000 at December 31,
1994 to $978,000 at December 31, 1995.

     Non-interest income declined by $513,112 or 17.8% from 1994 to 1995.
Included in 1994 non-interest income is $814,035 of non-recurring gains realized
from the sale of certain banking units. This decrease was offset  in 1995 by
increases of $42,097 in gains on sale of loans, and decreases in securities
losses of $304,809.

     Non-interest expense increased by $731,881 or 7.1% from 1994 to 1995.
Included in the change are increases in salaries and benefits of $723,642,
increases in occupancy expense of $35,962, and increases in equipment expense of
$92,715, offset by a decrease in other operating expense of $120,438.

     BCG recognized an income tax provision of $930,750 for 1995, compared to a
tax benefit of $151,321 for 1994.  The net increase in expense for 1995 compared
to 1994 was due to the recognition of deferred tax assets of AmeriCorp (through
reduction of the valuation allowance) during 1994 of approximately $1,197,000.
A reduction in the valuation allowance of approximately $439,000 was recognized
in 1995.

     INFLATION.  Although inflation affects the growth of total assets, it is
difficult to measure its impact precisely.  Net income is also affected by
inflation, but again there is no simple way to measure its effect on the various
types of income and expense.  Interest rates and operating expense, in
particular, are significantly affected by inflation, but neither the timing nor
the magnitude of interest-rate changes coincide with changes in the Consumer
Price Index.

     Due to the complexities of measuring the effects of inflation on BCG's
consolidated financial statements, management believes that it would be
misleading to attempt to quantify those effects.

     ACCOUNTING FOR IMPAIRMENT OF A LOAN.  As of January 1, 1995, BCG adopted
SFAS 114, "Accounting by Creditors for Impairment of a Loan."  SFAS 114 requires
that impaired loans be measured based on the present value of expected future
cash flows discounted at the loan's effective interest rate, which is the
contractual interest rate adjusted for any deferred loan fees or costs, premium
or discount, existing at the inception or acquisition of the loan, or at the
loan's observable market price, or at the fair value of the collateral of the
loan if the loan is collateral dependent.  As of January 1, 1995, BCG adopted
SFAS 118, "Accounting by Creditors for Impairment of a Loan-Income Recognition
and Disclosures" which amends SFAS 114 to require information about the recorded
investment in certain impaired loans and eliminates the provisions of SFAS 114
regarding how a creditor should report income on a impaired loan. SFAS 118
allows creditors to use existing methods for recognizing income on impaired
loans, including methods used by certain industry regulators. As of the date of
adoption, and as of December 31, 1995, the impact of SFAS 114 and SFAS 118 is
not considered material to BCG's consolidated financial statements.  Based on
the immaterial amount of impaired loans and management's current policies
regarding providing for losses on problem loans, there have been no policy
changes as a result of the implementation of SFAS 114 and 118.

      RISK ELEMENTS.  The allowance for loan losses at December 31, 1996 was
$2,849,340 or 7.4% higher than at December 31, 1995.  At December 31, 1996 the
allowance represented 1.50% of total loans as compared with 1.46% at December
31, 1995. At December 31, 1996 non-performing loans represented .38% of total
gross 

                                       44
<PAGE>
 
loans as compared with .55% at December 31, 1995. The allowance for loan losses
as a percentage of non-performing loans was 394% at December 31, 1996 as
compared with 263% at December 31, 1995.

     CAPITAL RESOURCES.  Shareholders' equity of $26,722,563 at December 31,
1996 reflects an increase of 20.2% over the same period in 1995, resulting in
book value per outstanding common share of $11.78 compared to $10.44 at December
31, 1995. Capital for BCG is above regulatory requirements, with GAAP equity of
9.21% of total assets at December 31, 1996.

     Set forth below are pertinent capital ratios for BCG as of December 31,
1996:

                      AND ANALYSIS OF FINANCIAL CONDITION
                        AND RESULTS OF OPERATIONS OF BCG

                   Three Months ended March 31, 1997 and 1996

EARNINGS SUMMARY

     Net income for the first three months of 1997 was $944,000, an increase of
$73,000 or 8.4% over the same period in 1996.  The net income per share for the
three months ended March 31, 1997 and 1996 was $.40 and $.40, respectively. Net
interest income for the three months ended March 31, 1997 increased $324,000 or
9.3% over the same period in 1996. The increase is primarily due to an increase
in net interest earning assets over the same period in 1996.

     The net interest margin, as a percentage of earning assets, decreased to
5.78% for the first three months of 1997 as compared to 5.89% for the same
period in 1996. Non-interest income for the three month period ended March 31,
1997 increased $133,000 or 20.8% over the same period in 1996. These increases
were primarily the result of increases in gains on sales of SBA loans and gains
on sales of other loans.

     Non-interest expense increased by $390,000 in the first three months of
1997 from the same period in 1996, an increase of 14.5%. Increases in salaries
and employee benefits of $436,000 or 28.5% and in occupancy and equipment
expense of $120,000  or 33% over similar periods in 1996 are related to the
addition of three branches added during 1996.

     For the first three months of 1997, return on equity was 13.9% on an
annualized basis versus 14.6% for the same period a year earlier. The decline in
return on equity was related to several factors, among which were the cessation
of tax benefits related to prior net operating losses from Ameribank and the
costs associated with the three new branches.

RISK ELEMENTS

     The allowance for loan losses at March 31, 1997  was $2,765,000 or 3.2 %
higher than at March 31, 1996.  At March 31, 1997,  the allowance represented
1.46 %  of total loans as compared with 1.42 % at March 31, 1996 and 1.50% at
December 31, 1996.  At March 31, 1997 non-performing loans represented .19% of
total loans as compared with .38% at December 31, 1996 and .48% at March 31,
1996.  The allowance for loan losses as a percentage of non-performing loans was
765% at March 31, 1997 as compared with 394% at December 31, 1996 and 794% at
March 31, 1996.

CAPITAL RESOURCES

     Shareholders' equity of $27,439,579 at March 31, 1997 increased 2.8% from
December 31, 1996 and 11% over the same period in 1996 resulting in book value
per outstanding common of share of $12.01 compared to $11.78 at December 31,
1996 and $10.76 at March 31, 1996. Capital for BCG is above regulatory
requirements, with GAAP equity of 9.07% of total assets at March 31, 1997
compared to 9.21% at December 31, 1996 and 9.05% at March 31, 1996.  The
increases in shareholders' equity was primarily the result of net earnings.

LIQUIDITY AND INTEREST RATE SENSITIVITY

     Liquidity management involves the ability to meet cash flow requirements of
customers who may be depositors making withdrawals or borrowers needing credit
funding.  BCG's cash flows are generated from interest and fee income, as well
as from loan repayments, deposit acquisition, and maturities or sales of
investments.  BCG's liquidity needs are provided for primarily through short-
term securities, and the maturing of loans.  Federal funds sold represent BCG's
primary source of immediate liquidity and were maintained at a level adequate to
meet immediate needs.  Federal funds averaged $23,111,000 and $11,360,000 for
the three months ended March 31, 1997 and March 31,1996, respectively.
Maturities  in BCG's loan and investment portfolios are monitored regularly to
avoid matching short-term deposits with long-term loans and investments.  Other
assets and liabilities are also monitored to provide the proper balance between
liquidity, safety, and profitability.  This monitoring process must be
continuous due to the constant flow of cash which is inherent in a financial
institution.

     BCG actively manages its interest rate sensitive assets and liabilities to
reduce the impact of interest rate fluctuations.  At March 31, 1997, BCG's rate
sensitive liabilities exceeded rate sensitive assets due within one year by
$17,600,000. BCG manages its liquidity through the volatility of its deposits
and patterns in loan demand, its current liquidity position, its ability to
control funding needs and potential sources of funds.  As part of managing
liquidity, BCG monitors its loan to deposit ratio on a daily basis.  The target
ratio is 85%.  At March 31, 1997 the ratio was 70%.

     BCG experienced a net increase in cash and cash equivalents, its primary
source of liquidity, of $10,366,537 during the first three months of 1997.
Operating activities provided $1,823,461 of funds.  Adjustments to net earnings
for non-cash expenses of depreciation, amortization, and provision for loan
losses are included in this amount as a net provision of funds.  Investing
activities used $4,011,113 of  funds, primarily due to an purchases of
securities available for sale of approximately $7,894,000 offset by calls and
maturities of securities available for sale of approximately $2,587,000, as well
as proceeds from the sale of  premises and equipment of approximately $773,000.
Financing activities provided $12,554,189 from an increase in deposits during
the three month period ended March 31, 1997.

         CERTAIN DIFFERENCES IN THE RIGHTS OF CSBI AND BCG SHAREHOLDERS
                                        
     At the Effective Time, BCG shareholders automatically will become
shareholders of CSBI, and their rights as shareholders will be determined by
CSBI's Articles and Bylaws. The following is a summary of the material
differences in the rights of shareholders of CSBI and BCG.  CSBI and BCG are
both Georgia corporations governed by the GBCC.  Except as set forth below,
there are no material differences between the rights of security holders of BCG
and CSBI under their respective Articles or Bylaws.    This summary does not
purport to be a complete discussion of, and is qualified in its entirety by
reference to the GBCC and the Articles and Bylaws of  each entity.

AUTHORIZED CAPITAL STOCK

     CSBI.  CSBI is authorized to issue 15,000,000 shares of common stock, $1.00
par value of which 7,767,459 shares were issued and outstanding as of March 31,
1997.  As of March 31, 1997, 50,000 shares of CSBI Common Stock were reserved
for issuance upon the exercise of outstanding stock options and purchases under
the CSBI Incentive Stock Option Plan, 500,000 shares were reserved pursuant to
the CSBI Dividend Reinvestment Plan, 100,000 shares were reserved pursuant to
the CSBI Employee Stock Ownership Plan, and 5,000 shares were reserved pursuant
to options granted to certain executive officers outside the CSBI Option Plan.

     BCG.   BCG is authorized to issue 3,000,000 shares of common stock, $1.00
par value  of which 2,268,097 shares were issued and outstanding as of March 31,
1997. As of March 31, 1997, 404,766 shares of BCG Common Stock were reserved for
issuance upon the exercise of outstanding stock options and purchases under  the
BCG Option Plan.

DIRECTORS

     CSBI.    The Bylaws of CSBI provide for a Board of Directors having not
less than five nor more than 15 members.  The number of directors may be
increased at any time by the  Board of Directors, or by a majority of the 

                                       48
<PAGE>
 
vote of the outstanding shares of CSBI Common Stock. Vacancies may be filled for
the unexpired term and until the shareholders have elected a successor, by the
affirmative vote of a majority of the remaining directors.

     Pursuant to CSBI's Bylaws and Georgia law, any director may be removed from
office with or without cause by the affirmative vote of the holders of a
majority of the votes entitled to be cast by the holders of voting stock of
CSBI.  Removal action may be taken at any shareholders meeting with respect to
which notice of such purpose has been given. A successor director may be elected
to serve the unexpired term at the same meeting.

     BCG.  The Bylaws of BCG provide for a board of directors of not less than
five nor more than 12 directors.  The number of directors may be increased or
decreased from time to time by the board of directors by amendment of the
Bylaws. Vacancies, but not including vacancies resulting from removal from
office by the shareholders, may be filled by a majority vote of the remaining
directors, or if no directors are in office, then by election by the
shareholders.

     BCG's Bylaws provide for the same method of removal of directors.  However,
if the vacancy created by the removal is not filled by a shareholder election
within 60 days after the removal, the remaining directors shall by majority
vote, fill the vacancy.

                       CERTAIN REGULATORY CONSIDERATIONS

HOLDING COMPANY REGULATION GENERALLY

     BCG is a registered bank holding company subject to regulation by the
Federal Reserve under the BHC Act.  BCG is required to file financial
information with the Federal Reserve periodically and is subject to periodic
examination by the Federal Reserve.

     The BHC requires every bank holding company to obtain the prior approval of
the Federal Reserve before (i) it may acquire direct or indirect ownership or
control of more than 5% of the voting shares of any bank that it does not
already control; (ii) it or any of its subsidiaries, other than a bank, may
acquire all or substantially all of the assets of a bank; and (iii) it may merge
or consolidate with any other bank holding company.  In addition, a bank holding
company is generally prohibited from engaging in, or acquiring, direct or
indirect control of the voting shares of any company engaged in non-banking
activities.  This prohibition does not apply to activities found by the Federal
Reserve, by order or regulation, to be so closely related to banking or managing
or controlling banks as to be a proper incident thereto.  Some of the activities
that the Federal Reserve has determined by regulation or order to be closely
related to banking are:  making or servicing loans and certain types of leases;
performing certain data processing services; acting as fiduciary or investment
or financial advisor; providing discount brokerage services; underwriting bank
eligible securities; underwriting debt and equity securities on a limited basis
through separately capitalized subsidiaries; and making investments in
corporations or projects designed primarily to promote community welfare.

     BCG must also register with the DBF and file periodic information with the
DBF.  As part of such registration, the DBF requires information with respect to
the financial condition, operations, management and intercompany relationships
of BCG and the BCG Banks and related matters.  The DBF may also require such
other information as is necessary to keep itself informed as to whether the
provisions of Georgia law and the regulations and orders issued thereunder by
the DBF have been complied with, and the DBF may examine BCG.

     BCG is an "affiliate" of the BCG Banks under the Federal Reserve Act, which
imposes certain restrictions on (i) loans by the Banks to BCG, (ii) investments
in the stock or securities of BCG by the Banks, (iii) the BCG Bank's taking the
stock or securities of an "affiliate" as collateral for loans by the BCG Banks
to a borrower and (iv) the purchase of assets from BCG by the BCG Banks.
Further, a bank holding company and its subsidiaries are prohibited from
engaging in certain tie-in arrangements in connection with any extension of
credit, lease or sale of property or furnishing of services.

     The BCG Banks are national banks chartered under the National Bank Act and
are subject to examination by the Office of the Comptroller of the Currency (the
"OCC").  The OCC regulates or monitors all areas of the BCG 

                                       49
<PAGE>
 
Bank's operations and activities, including reserves, loans, mergers, issuance
of securities, payments of dividends, interest rates and establishment of
branches.

PAYMENT OF DIVIDENDS

     BCG is a legal entity separate and distinct from the BCG Banks.  Most of
the revenues of BCG result from dividends paid to it by the BCG Banks.  There
are statutory and regulatory requirements applicable to the payment of dividends
by the BCG Banks, as well as by BCG to its shareholders.

     Under the regulations of the OCC, the BCG Banks may declare dividends out
of their net profits.  The approval of OCC is required if the total of all
dividends declared by a national banking association exceed the total of its net
profits for the year combined with its retained net profits for the preceding
two years.

     The payment of dividends by BCG and the BCG Banks may also be affected or
limited by other factors, such as the requirement to maintain adequate capital
above regulatory guidelines.  In addition, if, in the opinion of the applicable
regulatory authority, a bank under its jurisdiction is engaged in or is about to
engage in an unsafe or unsound practice (which, depending upon the financial
condition of the Banks, could include the payment of dividends), such authority
may require, after notice and hearing, that such bank cease and desist from such
practice. For 1996, BCG's cash dividend payout to stockholders was 6.8% of net
income.

MONETARY POLICY

     The results of operations of the BCG Banks are affected by credit policies
of monetary authorities, particularly the Federal Reserve.  The instruments of
monetary policy employed by the Federal Reserve include open market operations
in U.S. government securities, changes in the discount rate on bank borrowings
and changes in reserve requirements against bank deposits.  In view of changing
conditions in the national economy and in the money markets, as well as the
effect of actions by monetary and fiscal authorities, including the Federal
Reserve, no prediction can be made as to possible future changes in interest
rates, deposit levels, loan demand or the business and earnings of the BCG
Banks.

CAPITAL ADEQUACY

     The Federal Reserve and the OCC have implemented substantially identical
risk-based rules for assessing bank and bank holding company capital adequacy.
These regulations establish minimum capital standards in relation to assets and
off-balance sheet exposures as adjusted for credit risk.  Banks and bank holding
companies are required to have (i) a minimum level of total capital (as defined)
to risk-weighted assets of 8%; (ii) a minimum Tier One Capital (as defined) to
risk-weighted assets of 4%; and (iii) a minimum stockholders' equity to risk-
weighted assets of 4%.  In addition, the Federal Reserve and the OCC have
established a minimum 3% leverage ratio of Tier One Capital to total average
assets for the most highly-rated banks and bank holding companies.  "Tier One
Capital" generally consists of common equity not including unrecognized gains
and losses on securities, minority interests in equity accounts of consolidated
subsidiaries and certain perpetual preferred stock less certain intangibles.
The Federal Reserve and the OCC will require a bank holding company and a bank,
respectively, to maintain a leverage ratio greater than 3% if either is
experiencing or anticipating significant growth or is operating with less than
well-diversified risks in the opinion of the Federal Reserve.  The Federal
Reserve and the OCC use the leverage ratio in tandem with the risk-based ratio
to assess the capital adequacy of banks and bank holding companies.

     The  OCC and the Federal Reserve have proposed amending the capital
adequacy standards to provide for the consideration of interest rate risk in the
overall determination of a bank's capital ratio, requiring banks with greater
interest rate risk to maintain adequate capital for the risk.  The proposed
revisions are not expected to have a significant effect on BCG's or the BCG
Banks' capital requirements, if adopted in their current form.

     Effective December 19, 1992, a new Section 38 to the Federal Deposit
Insurance Act implemented the prompt corrective action provisions that Congress
enacted as a part of the Federal Deposit Insurance Corporation Improvement Act
of 1991 (the "1991 Act").  The "prompt corrective action" provisions set forth
five regulatory zones in which all banks are placed largely based on their
capital positions.  Regulators are required to take 

                                       50
<PAGE>
 
increasingly harsh action as a bank's financial condition declines. Regulators
are also empowered to place in receivership or require the sale of a bank to
another depository institution when a bank's capital leverage ratio reaches two
percent. Better capitalized institutions are generally subject to less onerous
regulation and supervision than banks with lesser amounts of capital.

     The FDIC has adopted regulations implementing the prompt corrective action
provisions of the 1991 Act, which place financial institutions in the following
five categories based upon capitalization ratios:  (i) a "well capitalized"
institution has a total risk-based capital ratio of at least 10%, a Tier One
risk-based ratio of at least 6% and a leverage ratio of at least 5%; (ii) an
"adequately capitalized" institution has a total risk-based capital ratio of at
least 8%, a Tier One risk-based ratio of at least 4% and a leverage ratio of at
least 4%; (iii) an "undercapitalized" institution has a total risk-based capital
ratio of under 8%, a Tier One risk-based ratio of under 4% or a leverage ratio
of under 4%; (iv) a "significantly undercapitalized" institution has a total
risk-based capital ratio of under 6%, a Tier One risk-based ratio of under 3% or
a leverage ratio of under 3%; and (v) a "critically undercapitalized"
institution has a leverage ratio of 2% or less.  Institutions in any of the
three undercapitalized categories would be prohibited from declaring dividends
or making capital distributions.  The FDIC regulations also establish procedures
for "downgrading" an institution to a lower capital category based on
supervisory factors other than capital.  Under the FDIC's regulations, the BCG
Banks are "well capitalized" institutions.

     Set forth below are pertinent capital ratios for each of the BCG Banks and
BCG as of December 31, 1996.

RECENT LEGISLATIVE AND REGULATORY ACTION

     On April 19, 1995, the four federal bank regulatory agencies adopted
revisions to the regulations promulgated pursuant to the Community Reinvestment
Act (the "CRA"), which are intended to set distinct assessment standards for
financial institutions.  The revised regulation contains three evaluation tests:
(i) a lending test which will compare the institution's market share of loans in
low-and moderate- income areas to its market share of loans in its entire
service area and the percentage of a bank's outstanding loans to low-and
moderate-income areas or individuals, (ii) a services test which will evaluate
the provisions of services that promote the availability of credit to low-and
moderate-income areas, and (iii) an investment test, which will evaluate an
institution's record of investments in organizations designed to foster
community development, small-and minority-owned businesses and affordable
housing lending, including state and local government housing or revenue bonds.
The regulation is designed to reduce some paperwork requirements of the current
regulations and provide regulators, institutions and community groups with a
more objective and predictable manner with which to evaluate the CRA performance
of financial institutions.  This regulation became effective on January 1, 1996
at which time evaluation under streamlined procedures began for institutions
with assets of less than $250 million that are owned by a holding company with
total assets of less than $1 billion.

have been increasingly concerned that prospective home buyers and other
borrowers are experiencing discrimination in their efforts to obtain loans.  In
recent years, the Department of Justice has filed suit against financial
institutions, which it determined had discriminated, seeking fines and
restitution for borrowers who allegedly suffered from discriminatory practices.
Most, if not all, of these suits have been settled (some for substantial sums)
without a full adjudication on the merits.

     On March 8, 1994, the Federal Agencies, in an effort to clarify what
constitutes lending discrimination and specify the factors that agencies will
consider in determining if lending discrimination exists, announced a joint
policy statement detailing specific discriminatory practices prohibited under
the Equal Credit Opportunity Act and the Fair Housing Act.  In the policy
statement, three methods of proving lending discrimination were identified:  (i)
overt evidence of discrimination, when a lender blatantly discriminates on a
prohibited basis, (ii) evidence of disparate treatment, when a lender treats
applicants differently based on a prohibited factor even where there is no
showing that the treatment was motivated by prejudice or a conscious intention
to discriminate against a person, and (iii) evidence of disparate impact, when a
lender applies a practice uniformly to all applicants, but the practice has a
discriminatory effect, even where such practices are neutral on their face and
are applied equally, unless the practice can be justified on the basis of
business necessity.

     On September 23, 1994, President Clinton signed the Reigle Community
Development and Regulatory Improvement Act of 1994 (the "Regulatory Improvement
Act").  The Regulatory Improvement Act contains funding for community
development projects through banks and community development financial
institutions and also numerous regulatory relief provisions designed to
eliminate certain duplicative regulations and paperwork requirements.

     On September 29, 1994, President Clinton signed the Reigle-Neal Interstate
Banking and Branching Efficiency Act of 1994 (the "Federal Interstate Bill")
which amended federal law to permit bank holding companies to acquire existing
banks in any state effective September 29, 1995, and any interstate bank holding
company is permitted to merge its various bank subsidiaries into a single bank
with interstate branches after May 31, 1997.  States have the authority to
authorize interstate branching prior to June 1, 1997, or alternatively, to opt
out of interstate branching prior to that date.  The Georgia legislature did not
opt out.

     On January 26, 1996, the Georgia Legislature adopted a bill (the "Georgia
Intrastate Bill") to permit, effective July 1, 1996, any Georgia bank or group
of affiliated banks under one holding company to establish new or additional
branch banks in any three counties within the State of Georgia in which it is
not currently operating.  After July 1, 1998, all restrictions on state-wide
branching will be removed.  Prior to adoption of the Georgia Intrastate Bill,
Georgia only permitted branching via merger or consolidation with an existing
bank or in certain other limited circumstances.

     On July 3, 1997, President Clinton signed legislation to clarify that
branches of  state-chartered banks, operating in host states are covered by the
laws of their home chartering state.  The Riegle-Neal Amendment Act of 1997 is
intended to preserve the dual banking system by having state banks come under
only the rules of their chartering states.  Other legislation dealing with bank
modernization is in various stages of the legislative process and no prediction
as to the outcome or the impact of such legislation can be made at this time.

FDIC INSURANCE ASSESSMENTS FOR THE BCG BANKS

     The BCG Banks are subject to FDIC deposit insurance assessments for the
Bank Insurance Fund (the "BIF").  In the first five months of 1995, the BCG
Banks were assessed $.23 per $100 of deposits, based on a risk-based system
whereby banks were assessed on a sliding scale depending upon their placement in
nine separate supervisory categories, from $.23 per $100 of deposits for the
healthiest banks (those with the highest capital, best management and best
overall condition) to as much as $.31 per $100 of deposits for the less-healthy
institutions.

                                       52

     On August 8, 1995, the FDIC lowered the BIF premium for healthy banks 83%
from $.23 per $100 in deposits to $.04 per $100 in deposits, while retaining the
$.31 level for the riskiest banks. The new rate took effect on September 29,
1995 retroactive to June 1, 1995.  On September 15, 1995, the FDIC refunded
$119,908 to the BCG Banks for premium overpayments in the second and third
quarter of 1995.  On November 14, 1995, the FDIC again lowered the BIF premium
for healthy banks from $.04 per $100 of deposits to zero for the highest rated
institutions (92% of the industry).  As a result, the BCG Banks have paid only
the legally required annual minimum payment of $2,000 per year for insurance
beginning in January 1996.  Had the current rates been in effect for all of 1994
and 1995, the annual FDIC insurance premiums paid by the BCG Banks would have
collectively been reduced by $588,908.

     On September 29, 1996, the Economic Growth and Regulatory Paperwork
Reduction Act of 1996 was enacted (the "1996 Act").  The 1996 Act's chief
accomplishment was to provide for the recapitalization of the Savings
Association Insurance Fund ("SAIF") by levying a one-time special assessment on
SAIF deposits to bring the fund to a reserve ratio equal to $.25 per $100 of
insured deposits and to provide that beginning in 1997, BIF assessments would be
used to help pay off the $780 million in annual interest payments on the $8
billion Financing Corporation ("FICO") bonds issued in the late 1980s as part of
the government rescue of the thrift industry.  The law provides that BIF
assessments for FICO bond payments must be set at a rate equal to 20% of the
SAIF rates for such assessments for 1997, 1998 and 1999.  After 1999, all FDIC
insured institutions will pay the same assessment rates.  For the first six
months of 1997, the assessment for the FICO bond payments will be $.0132 per
$100 of deposits for BIF deposits and $.0648 per $100 of deposits for SAIF
deposits.

BCG FINANCIAL STATEMENTS.


              REPORT OF INDEPENDENT CERTIFIED  PUBLIC ACCOUNTANTS


The Board of Directors and Shareholders
Bank Corporation of Georgia
Macon, Georgia


     We have audited the accompanying consolidated balance sheets of Bank
Corporation of Georgia and subsidiaries as of December 31, 1996 and 1995, and
the related consolidated statements of earnings, changes in shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1996.  These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Bank
Corporation of Georgia and subsidiaries as of December 31, 1996 and 1995, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1996, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of the Company and its subsidiaries,
     and the methods of applying these principles, conform with generally
     accepted accounting principles and with general practice within the banking
     industry. The more significant accounting policies are described in this
     summary.

     In preparing the financial statements, management is required to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities as of the date of the balance sheet and income and expenses for
     the year. Actual results could differ significantly from those estimates.
     Material estimates common to the banking industry that are particularly
     susceptible to significant change in an operating cycle of one year
     include, but are not limited to, the determination of the allowance for
     loan losses, the valuation of any real estate acquired in connection with
     foreclosures or in satisfaction of loans, and valuation allowances
     associated with the realization of deferred tax assets which are based on
     future taxable income.

     CONSOLIDATION

     The consolidated financial statements include the accounts of Bank
     Corporation of Georgia (the "Company") and its wholly-owned bank
     subsidiaries, First South Bank, N.A. ("FSB"), First South Bank of Coweta
     County, N.A. ("Coweta"), First South Bank of Middle Georgia, N.A. ("Middle
     Georgia") and First South Bank of Ben Hill County, N.A. ("Ben Hill").
     During 1996, Coweta and Middle Georgia were merged with FSB.  During 1994,
     the Company sold Ben Hill and the Ashburn, Georgia branch of FSB.

     The financial statements also include the accounts of AmeriCorp, Inc.
     ("AmeriCorp") and its wholly-owned bank subsidiary AmeriBank, N.A.
     ("AmeriBank"). During 1996, AmeriCorp was dissolved upon the Company's
     purchase of the remaining minority interest, and AmeriBank became a wholly-
     owned subsidiary of the Company.

     In consolidation, all significant intercompany accounts and transactions
     have been eliminated.

     CASH AND CASH EQUIVALENTS

     Cash equivalents include amounts due from banks, interest-bearing
     deposits with other banks due within three months, federal funds sold and
     overnight investments with the Federal Home Loan Bank.

     Included in cash and due from banks are interest bearing deposits with the
     Federal Home Loan Bank amounting to $18,642,250 and $44,751 at December 31,
     1996 and 1995, respectively.

     INVESTMENT SECURITIES AND INVESTMENT SECURITIES AVAILABLE FOR SALE

     The Company classifies its securities in one of three categories: trading,
     available for sale, or held to maturity. Trading securities are bought and
     held principally for the purpose of selling them in the near term. Held to
     maturity securities ("Investment Securities") are those securities for
     which the Company has the ability and intent to hold until maturity. All
     other securities not included in trading or held to maturity are classified
     as available for sale ("Securities AFS").

     Securities AFS are recorded at fair value.  Investment securities are
     recorded at cost, adjusted for the amortization of premiums or accretion of
     discounts. Unrealized holding gains and losses, net of the related tax
     effect, on Securities AFS are excluded from earnings and are reported as a
     separate component of shareholders' equity until realized. Transfers of
     securities between categories are recorded at fair value at the date of
     transfer. Unrealized holding gains or losses associated with transfers from
     Investment Securities to Securities AFS are recorded as a separate
     component of shareholders' equity.  The unrealized holding gains or losses
     included in the separate component of shareholders' equity for securities
     transferred from Securities AFS to Investment Securities are maintained and
     amortized into earnings over the remaining life

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                        
     of the security as an adjustment to yield in a manner consistent with the
     amortization or accretion of premium or discount on the associated
     security.


     INVESTMENT SECURITIES AND INVESTMENT SECURITIES AVAILABLE FOR SALE,
     CONTINUED

     A decline in the market value of any Investment Securities or Securities
     AFS below cost that is deemed other than temporary is charged to earnings
     and establishes a new cost basis for the security.

     Premiums and discounts are amortized or accreted over the life of the
     related security as an adjustment to the yield. Realized gains and losses
     for securities classified as Securities AFS and Investment Securities are
     included in earnings and are derived using the specific identification
     method for determining the cost of securities sold.

     LOANS

     Loans are stated at the principal amount outstanding, net of unearned
     interest and the allowance for loan losses. Interest income on loans is
     recognized on the effective yield method.  Nonrefundable loan fees and
     certain direct loan origination costs are accounted for in accordance with
     Statement of Financial Accounting Standard (SFAS) No. 91, "Accounting for
     Nonrefundable Fees and Costs Associated with Originating or Acquiring Loans
     and Initial Direct Costs of Leases."  SFAS No. 91 requires recognition of
     loan origination fees, net of direct costs, over the life of the related
     loan as an adjustment to yield.

     Effective January 1, 1995, the Company adopted SFAS No. 114, "Accounting
     by Creditors for Impairment of a Loan" amended by SFAS No. 118, "Accounting
     by Creditors for Impairment of a Loan - Income Recognition and Disclosure"
     in regards to accounting for impaired loans. A loan is impaired when, based
     on current information and events, it is probable that all amounts due
     according to the contractual terms of the loan agreement will not be
     collected.  Impaired loans are measured based on the present value of
     expected future cash flows discounted at the loan's effective interest
     rate, or at the loan's observable market price, or at the fair value of the
     collateral of the loan if the loan is collateral dependent. The adoption of
     these standards had no material effect on earnings.

     The Banks are parties to agreements with the Federal Home Loan Bank of
     Atlanta, ("FHLB"). The agreements allow for advances by the FHLB at varying
     rates, secured by the Bank's stock in the FHLB, and certain 1-4 family,
     first mortgage loans, up to 75% of the outstanding balances of these
     residential loans. No advances were outstanding at December 31, 1996. At
     December 31, 1995, the Banks had total advances of $6,100,000.

     UNEARNED DISCOUNT

     The unearned discount on loans purchased is recognized over the remaining
     lives of the loans using the effective yield method.

     ALLOWANCE FOR LOAN LOSSES

     The allowance for loan losses is established through a provision for
     loan losses charged to expense. The allowance represents an amount which,
     in management's judgement, will be adequate to absorb losses on existing
     loans that may become uncollectible.  Management's judgement in determining
     the adequacy of the allowance is based on evaluations of the collectibility
     of loans. These evaluations take into consideration such factors as changes
     in the nature and volume of the loan portfolio, current economic conditions
     that may affect the borrower's ability to pay, overall portfolio quality,
     and review of specific problem loans.

     Management's judgement in determining the adequacy of the allowance is
     based on evaluations of the collectibility of loans. These evaluations take
     into consideration such factors as changes in the nature and volume of the
     loan portfolio, current economic conditions that may affect the borrower's
     ability to pay, overall portfolio quality, and review of specific problem
     loans.

     Management believes that the allowance for loan losses is adequate.
     While management uses available information to recognize losses on loans,
     future additions to the allowance may be necessary based on changes in
     economic conditions. In addition, various regulatory agencies, as an
     integral part of their examination process, periodically review the
     Company's allowance for loan losses.  Such agencies may require the Company
     to recognize additions to the allowance based on judgments different than
     those of management.


     PREMISES AND EQUIPMENT

     Premises and equipment are stated at cost, less accumulated
     depreciation.  Major additions and improvements are charged to the property
     accounts while replacements, maintenance and repairs, which do not improve
     or extend the life of respective assets, are expensed currently.  When
     property is retired or otherwise disposed of, the cost and related
     accumulated depreciation are removed from the accounts and the resulting
     gain or loss, if any, is recognized.  Depreciation expense is computed
     principally on the straight-line method over the following estimated useful
     lives:

          Buildings and improvements           15 - 40 years
          Furniture, fixtures and equipment     5 - 10 years
          Computer equipment                    3 - 5 years

     INTANGIBLE ASSETS

     The unamortized cost in excess of fair value of net assets acquired in
     bank acquisitions ("goodwill") amounted to approximately $1,323,000 and
     $394,000 at December 31, 1996 and 1995, respectively.  Goodwill is being
     amortized on a straight-line basis with periods ranging from 15 to 25
     years.

     401(K) PLAN

     The Company has a retirement plan qualified pursuant to Internal Revenue
     Code Section 401(k) ("401(k) Plan"). The 401(k) Plan covers substantially
     all employees subject to certain minimum age and service requirements.
     Contributions to the plan by employees is voluntary; however, the Company
     will match a minimum of 25% of the employee's contributions. Contributions
     to the plan charged to expense for the years ended December 31, 1996, 1995
     and 1994 amounted to approximately $81,000, $153,000 and $151,000,
     respectively.

     EMPLOYEE STOCK OWNERSHIP PLAN

     The Company sponsors a leveraged employee stock ownership plan ("ESOP")
     that covers substantially all employees subject to certain minimum age and
     service requirements. The Company makes contributions to the ESOP which the
     plan trustee is required to use to make loan principal and interest
     payments. All dividends received by the ESOP are used to pay debt service.
     The ESOP shares initially were pledged as collateral for its debt. As the
     debt is repaid, shares are released from collateral and allocated to active
     employees, based on the proportion of debt service paid in the year. The
     Company accounts for its ESOP in accordance with Statement of Position 93-6
     (SOP 93- 6). Accordingly, the debt of the ESOP is recorded as debt and the
     shares pledged as collateral are reported as unearned ESOP shares in the
     statement of

     considered "old ESOP" shares as defined by SOP 93-6; therefore, as shares
     are released from collateral, the Company reports compensation expense
     equal to the cost of the shares, and the shares become outstanding for
     earnings per share computations.  Dividends on allocated ESOP shares are
     recorded as a reduction of retained earnings; dividends on unallocated ESOP
     shares are recorded as a reduction of debt and accrued interest.  ESOP
     compensation expense was $74,300, $69,800 and $64,600 for years ended
     December 31, 1996, 1995 and 1994, respectively.  The ESOP shares as of

     INCOME TAXES

     The Company accounts for income taxes pursuant to the asset and
     liability method which requires the recognition of deferred tax assets and
     liabilities for the future tax consequences attributable to differences
     between the financial statement carrying amounts of existing assets and
     liabilities and their respective tax bases.  Additionally, the method
     requires the recognition of future tax benefits, such as net operating loss
     carryforwards, to the extent that realization of such benefits is more
     likely than not. Deferred tax assets and liabilities are measured using
     enacted tax rates expected to apply to taxable income in the years in which
     the assets and liabilities are expected to be recovered or settled.  The
     effect on deferred tax assets and liabilities of a change in tax rates is
     recognized in income tax expense in the period that includes the enactment
     date.

     In the event the future tax consequences of differences between the
     financial reporting bases and the tax bases of the Company's assets and
     liabilities results in deferred tax assets, an evaluation of the
     probability of being able to realize the future benefits indicated by such
     asset is required.  A valuation allowance is provided for the portion of
     the deferred tax asset when it is more likely than not that some portion or
     all of the deferred tax asset will not be realized.  In assessing the
     realizability of the deferred tax assets, management considers the
     scheduled reversals of deferred tax liabilities, projected future taxable
     income, and tax planning strategies.

     INTEREST RATE RISK MANAGEMENT

     As part of the Company's overall interest rate risk management, the
     Company uses interest rate swaps and interest rate floors.  These contracts
     are designated by the Company as hedges of interest rate exposures, and
     interest income or expense derived from these contracts is recorded over
     the life of the contract as an adjustment to interest income or expense.

     NET EARNINGS PER SHARE

     Net earnings per share are based on the weighted average number of shares
     outstanding during each year including consideration of stock options,
     which represent common stock equivalents. It is assumed that all

     dilutive stock options are exercised at the beginning of the year and that
     the proceeds are used to purchase shares of the Company's common stock.
     The average market price during each year is used to compute equivalent
     shares assumed to be acquired for primary earnings per share, whereas year-
     end prices are used for fully diluted per-share amounts. Unearned ESOP
     shares are not considered outstanding for purposes of earnings per share.

(2)  ACQUISITIONS AND SALES

     In November 1990, the Company acquired a 25% interest in the common stock
     of AmeriCorp through the purchase of newly issued shares of AmeriCorp.
     During 1992, the Company increased its ownership interest to 34% and in
     December 1993 further increased its ownership to 67%. These investments in
     AmeriCorp comprised both cash invested by the Company and stock issued by
     AmeriCorp for management fees and accrued interest payable to the Company.
     In March 1996, the Company issued 149,215 of its $1 par value common stock
     in exchange for all of the remaining outstanding shares of AmeriCorp and
     additionally paid certain acquisition costs. Dissenting and fractional
     AmeriCorp shareholders were paid $67,432. The Company accounted for this
     transaction, as well as incremental stock purchases, using the purchase
     method. The reported purchase price for AmeriCorp was based on the fair
     market value of the assets acquired and liabilities assumed as of the
     closing dates, and the results of all operations have been included in the
     consolidated financial statements since the initial 1990 acquisition, net
     of respective minority interests for each year.

     The Company had also made investments in AmeriCorp through the purchase of
     preferred stock. The preferred stock, which was not convertible into common
     stock, required the payment of dividends in cash or additional preferred
     stock at a fixed rate of 8%. It was redeemable at the option of AmeriCorp
     and contained liquidation preferences at par value.

     At the time that the remaining AmeriCorp common stock was acquired in 1996,
     the Company liquidated AmeriCorp through the payment of dividends-in-kind
     of the remaining net assets of AmeriCorp including its investment in its
     wholly-owned subsidiary, AmeriBank, and cancelled AmeriCorp's common and
     preferred stock.

     In February 1996, AmeriBank acquired certain assets and assumed certain
     liabilities of the Victory Drive branch in Savannah, Georgia of Bank South,
     N.A.  As the result of the assumption of certain deposit and other
     liabilities and the purchase of certain loans and other assets, AmeriBank
     received $12,687,620 at closing. The excess purchase price over fair value
     of the net liabilities assumed (goodwill) was approximately $355,000 and is
     being amortized over 15 years using the straight line method.

     In June 1996, the Company acquired all of the outstanding common stock of
     Effingham Bank & Trust ("Effingham"), a $25 million commercial bank located
     in Rincon, Georgia in exchange for 204,928 shares of its $1 par value
     common stock and approximately $53,352 paid for dissenting and fractional
     shares. The number of shares exchanged for Effingham stock included 16,225
     shares exchanged for Effingham shares under options which were exercised
     during 1995 prior to the merger. The acquisition was accounted for as a
     pooling of interests and, accordingly, the consolidated financial
     statements for all periods presented have been restated to include the
     financial position and results of operations as if the combination had
     occurred on January 1, 1994.

     In March 1994, FSB sold substantially all the assets and liabilities of
     its Ashburn banking unit to Ashburn Bank. The sale resulted in a cash

(7)  SHAREHOLDERS' EQUITY

     During 1995, the Company's Board of Directors authorized a stock split
     to be effected in the form of a 75% stock dividend. All references in the
     financial statements to number of shares, per share amounts, and stock
     option and ESOP data have been adjusted for the stock split.

     The Company has a Stock Option Plan under which a maximum of 404,766
     shares of common stock have been reserved. The Plan also contains certain
     stock appreciation rights whereby the Company would pay in cash or stock an
     amount up to 200% of the excess of the fair market value of the Company's
     stock at the date of exercise over the fair market value at the grant date.
     Exercise of either the stock options or the stock appreciation rights
     precludes exercise of the other.

     SFAS No. 123, "Accounting for Stock-Based Compensation," became effective
     January 1, 1996. This statement encourages, but does not require, entities
     to compute the fair value of options at the date of grant and to recognize
     such costs as compensation expense immediately if there is no vesting
     period or ratably over the vesting period of the options. The Company has
     chosen not to adopt the cost recognition principles of this statement. No
     compensation cost has been recognized for the stock option plan. Had
     compensation cost for the plan been determined based upon the fair value of
     the options at the grant dates consistent with the methods as provided in
     SFAS No. 123, "Accounting for Stock-Based Compensation," the Company's net
     earnings and net earnings per share would have been reduced to the proforma
     amounts indicated below:

</TABLE>

     The fair value of each option is estimated on the date of grant using the
     Black-Scholes options-pricing model with the following weighted average
     assumptions used for grants in 1996: dividend yield of 1%, volatility of
     34%, a risk free interest rate of 6%, and an expected life of 8 years.

     A summary status of the Company's Stock Option Plan as of December 31, 1996
     and 1995, and changes during the years ending on those dates is presented

(7)  SHAREHOLDERS' EQUITY, CONTINUED

     Options outstanding at December 31, 1996 had exercise prices ranging from
     $5.57 to $13.00, with a weighted average exercise price of $7.16, and an
     average remaining life of approximately 5 years.

     Included in salaries and employee benefits expense for 1995 was
     approximately $20,000 related to the exercise of 3,500 stock appreciation
     rights by officers of the Company. There were no stock appreciation rights
     exercised in 1996. Compensation expense is not being recorded on the
     unexercised stock appreciation rights since, in management's opinion, there
     is a higher probability that the stock options will be exercised.

     The loan agreement covering the Company's $1,500,000 note payable restricts
     the payment of dividends by bank subsidiaries to the amount as permitted by
     the regulators and requires that the subsidiaries remain in compliance with
     certain capital levels specified in the loan agreement. The loan agreement
     further restricts the payment of cash dividends by the Company to its
     stockholders. In any year, the Company may not, without advance approval by
     the lender, pay dividends which together with the dividends paid in the
     preceding two years, exceed 25% of consolidated net earnings for the three
     year period.

     The deferred tax asset valuation allowance reflects management's estimate
     of future tax benefits from Federal and State of Georgia net operating loss
     carryforwards and credits included in the total deferred tax asset, which
     may not be realized based on the weight of available evidence. During 1994
     and 1995, the Company reduced the beginning of the year valuation allowance
     at AmeriCorp to reflect changes in judgement as to the realizability of the
     AmeriCorp and AmeriBank net operating losses as they began to generate
     sufficient and predictable current taxable income during these two years.
     The Effingham deferred tax asset valuation allowance was reduced effective
     with its acquisition by the Company.

     Prior to 1996, AmeriCorp and AmeriBank filed separate consolidated and
     Effingham filed separate Federal and State of Georgia income tax returns.
     After the 1996 acquisitions, AmeriCorp, AmeriBank and Effingham are
     included in the consolidated Company Federal and State of Georgia income
     tax returns. Consolidated Federal and Georgia tax net operating losses,
     approximating $4,600,000 and $8,955,000 at December 31, 1996, respectively,
     are available to offset future consolidated taxable income.  The use of
     these carryforwards is limited to future consolidated taxable earnings and
     to annual limitations imposed by the Internal Revenue Code. The Company may
     use no more than $1,007,000 annually of its remaining Federal and State of
     Georgia net operating losses which begin to expire in 2002.

(10) COMMITMENTS AND CONTINGENCIES

     The Banks are parties to financial instruments with off-balance-sheet
     risk in the normal course of business to meet the financing needs of their
     customers. These financial instruments include commitments to extend credit
     and standby letters of credit. Those instruments involve, to varying
     degrees, elements of credit risk in excess of the amount recognized in the
     balance sheet. The contractual amounts of those instruments reflect the
     extent of involvement the Banks have in particular classes of financial
     instruments.

     The Banks' exposure to credit loss in the event of non-performance by
     the other party to the financial instrument for commitments to extend
     credit and standby letters of credit is represented by the contractual
     amount of those instruments.  The Banks use the same credit policies in
     making commitments and conditional obligations as they do for on-balance-
     sheet instruments.

     In most cases, the Banks require collateral or other security to support
     financial instruments with credit risk.

            Financial instruments whose contract amounts
            represent credit risk:
               Commitments to extend credit                          $13,720,000          18,554,000

</TABLE>

     Commitments to extend credit are agreements to lend to a customer as long
     as there is no violation of any condition established in the contract.
     Commitments generally have fixed expiration dates or other termination
     clauses and may require payment of a fee. Since many of the commitments may
     expire without being drawn upon, the total commitment amounts do not
     necessarily represent future cash requirements. The Banks evaluate each
     customer's creditworthiness on a case-by-case basis. The amount of
     collateral obtained, if deemed necessary, upon extension of credit is based
     on management's credit evaluation. Collateral held varies but may include
     unimproved and improved real estate, certificates of deposit, or personal
     property.

     Standby letters of credit are conditional commitments issued by the Banks
     to guarantee the performance of a customer to a third party. The credit
     risk involved in issuing letters of credit is essentially the same as that
     involved in extending loan facilities to customers. The extent of
     collateral held for those commitments at December 31, 1996 and 1995 varies.

     The Company has entered into certain agreements for the purpose of managing
     its exposure to short term interest rate fluctuations. Notional amounts are
     used to express the volume of these transactions, however, they do not
     represent cash flows and the amounts subject to credit risk are much
     smaller.

     The Company entered into several interest rate swap agreements during 1995
     and 1996 to manage its exposure to short-term interest rate fluctuations.
     At December 31, 1996, five agreements were outstanding with aggregate
     notional amounts of $25,000,000, and maturities ranging from August 1997
     through November 1999. Under the terms of the agreements, the Company will
     receive fixed rates of interest averaging approximately 6.32%, while paying
     floating rates of interest based on the three month LIBOR. Weighted average
     rates paid by the Company during 1996 were approximately 5.53%.

     In addition the Company has purchased interest rate floor contracts with
     aggregate notional amounts of $30,000,000, maturing in March 1997.  Under
     the terms of the agreement, the Company will be reimbursed on a quarterly
     basis for decreases in the federal funds rate for any period during the
     agreement in which the federal funds rate falls below 5.5%.  At December
     31, 1996, the federal funds rate was 5.25%.  Amortization of premiums
     related to the purchase of these contracts amounted to approximately
     $44,000 for 1996.

     During 1996, in anticipation of the maturity of the interest rate floor
     contracts in March 1997, the Company entered into forward interest rate
     floor contracts effective beginning April, 1997 with aggregate notional
     amounts of $30,000,000 maturing through May, 1999.  Under the terms of
     these agreements, the Company will be reimbursed on a quarterly basis, for
     decreases in the federal funds rate for any period during the agreement in
     which the federal funds rate falls below 5.0%.  Amortization of premiums
     related to the purchase of these contracts amounted to approximately
     $26,000.

     The Company is exposed to credit loss in the event of non-performance by
     the other party to the interest rate floor and interest rate swap
     agreements; however, based on management's credit analysis, the Company
     does not anticipate non-performance by the counterparty.

     During 1996, AmeriBank assumed the lease of a branch facility.  The minimum
     lease payments amount to approximately $17,000 per month and are subject to
     increases based on the Consumer Price Index and other costs.  The lease
     agreement expires in December 2007.

(11) RELATED PARTY TRANSACTIONS

     In the normal course of business, executive officers and directors of the
     Company and certain business organizations and individuals associated with
     them, maintain a variety of banking relationships with the Banks.
     Transactions with executive officers and directors are made on terms
     comparable to those available to other Bank customers.  The following table
     summarizes related party loan activity during 1996:

     The Company leases its administrative office under an operating lease 
     arrangement with the Chairman of the Board of Directors. The lease term 
     extends through January, 2003 and is renewable for 8 years at that time. 
     Rental expense under this agreement will amount to approximately $84,000 
     annually.

     Outstanding deposits to related parties amounted to approximately 
     $8,238,000 and $8,156,000 at December 31, 1996 and 1995, respectively.

(12) DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

     SFAS No. 107, "Disclosures about Fair Value of Financial
     Instruments", requires that the Company disclose estimated fair values for
     its financial instruments.  Fair value estimates, methods, and assumptions
     are set forth below.

          CASH AND CASH EQUIVALENTS
          For cash, due from banks, federal funds sold and interest-bearing 
          deposits with other banks due within three months, the carrying 
          amount is a reasonable estimate of fair value.

          INVESTMENT SECURITIES AND INVESTMENT SECURITIES AVAILABLE FOR SALE
          For securities held for investment purposes, fair values are based 
          on quoted market prices.

                                      F-21

                  BANK CORPORATION OF GEORGIA AND SUBSIDIARIES
                                        
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                        
     LOANS

     The fair value of fixed rate loans is estimated by discounting the future
     cash flows using the current rates at which similar loans would be made to
     borrowers with similar credit ratings. For variable rate loans, the 
     carrying amount is a reasonable estimate of fair value.

(12) DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS, CONTINUED

     DEPOSIT LIABILITIES

     The fair value of demand deposits, savings accounts, and certain money 
     market deposits is the amount payable on demand at the reporting date. 
     The fair value of fixed maturity certificates of deposit is estimated 
     using the rates currently offered for deposits of similar remaining 
     maturities.

     NOTES PAYABLE

     Because the Company's notes payable carry a variable rate, the carrying 
     amount is a reasonable estimate of fair value.

     FHLB ADVANCES

     The fair value of FHLB Advances is estimated by discounting the future 
     cash flows using the current rates at which advances of like maturity 
     would be made.

     COMMITMENTS TO EXTEND CREDIT, STANDBY LETTERS OF CREDIT AND
     FINANCIAL GUARANTEES WRITTEN

     Because commitments to extend credit and standby letters of credit are 
     made using variable rates and are for terms less than one year, the 
     contract value is a reasonable estimate of fair value.

     INTEREST RATE SWAPS AND INTEREST RATE FLOORS

     The fair value of interest rate swaps and interest rate floors is obtained
     from dealer quotes. These values represent the estimated amount the 
     Company would receive to terminate the contracts or agreements, taking 
     into account current interest rates and when appropriate, the current 
     creditworthiness of the counterparties.

     LIMITATIONS

     Fair value estimates are made at a specific point in time, based on 
     relevant market information and information about the financial 
     instrument. These estimates do not reflect any premium or discount that 
     could result from offering for sale at onetime the Company's entire 
     holdings of a particular financial instrument. Because no market exists 
     for a significant portion of the Company's financial instruments, fair 
     value estimates are based on many judgments. These estimates are 
     subjective in nature and involve uncertainties and matters of significant
     judgement and therefore cannot be determined with precision. Changes in
     assumptions could significantly affect the estimates.

     Fair value estimates are based on existing on and off-balance sheet 
     financial instruments without attempting to estimate the value of 
     anticipated future business and the value of assets and liabilities that 
     are not considered financial instruments. Significant assets and 
     liabilities that are not considered financial instruments include 
     deferred income taxes, premises and equipment, and goodwill. In addition,
     the tax ramifications related to the realization of the unrealized gains 
     and losses can have a significant effect on fair value estimates and have
     not been considered in the estimates.

(13) REGULATORY MATTERS

     The Banks and the Company are subject to various regulatory capital
     requirements administered by the federal banking agencies.  Failure to meet
     minimum capital requirements can initiate certain mandatory and possibly
     additional discretionary actions by regulators that, if undertaken, could
     have a direct material effect on the Banks' financial statements.  Under
     certain adequacy guidelines and the regulatory framework for prompt
     corrective action, the Banks must meet specific capital guidelines that
     involve quantitative measures of the Banks' assets,  liabilities, and
     certain off-balance-sheet items as calculated under regulatory accounting
     practices.  The Banks' capital amounts and classification are also subject
     to qualitative judgments by the regulators about components, risk
     weightings, and other factors.

     Quantitative measures established by regulation to ensure capital
     adequacy require the Banks to maintain minimum amounts and ratios of total
     and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average
     assets.  Management believes, as of December 31, 1996, that the Bank meets
     all capital adequacy requirements to which it is subject.

     As of December 31, 1996, the most recent notification from the
     Comptroller of the Currency categorized the Banks as well capitalized under
     the regulatory framework for prompt corrective action.  To be categorized
     as well capitalized the Banks must maintain minimum total risk-based, Tier
     1 risk-based and Tier 1 leverage ratios as set forth in the table.  There
     are no conditions or events since that notification that management
     believes have changed the Bank's category.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The financial statements included herein have been prepared by BCG, without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission.  Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to such rules and
regulations, although BCG believes that the disclosures contained herein are
adequate to make the information presented not misleading.  In the opinion of
management, the information furnished in the condensed consolidated financial
statements reflects all adjustments which are ordinary in nature and necessary
to present fairly BCG's financial position, results of operations and changes in
financial position for such interim period.  These financial statements should
be read in conjunction with BCG's financial statements and the notes thereto as
of December 31, 1996, included in BCG's annual report on Form 10KSB for the year
ended December 31, 1996.  BCG is a bank holding company whose business is
primarily conducted by its wholly-owned banking subsidiaries First South Bank,
N. A. ("FSB") and Ameribank, N. A. ("Ameribank").  The accounting principles
followed by BCG and its subsidiaries, and the methods of applying those
principles conform with generally accepted accounting principles and with
general practices within the banking industry, where applicable.

During 1997, the Financial Accounting Standards Board has issued Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS 128).  SFAS
128 supersedes APB Opinion 15.  SFAS 128 simplifies current standards by
eliminating the presentation of primary EPS and requiring the presentation of
basic EPS, which includes no potential common shares and thus no dilution.  The
Statement also requires entities with complex capital structures to present
basic and diluted EPS on the face of the income statement and also eliminates
the modified treasury stock method of computing potential common shares.  The
Statement is effective for financial statements issued for periods ending after
December 15, 1997, including interim periods.  Early application is not
permitted.  On adoption, restatement of all prior-period EPS data presented is
required.  Presently, BCG is unable to determine the impact that adoption of
SFAS 128 will have on the consolidated financial statements, but management
anticipates that the impact will not be material.

Banking and Finance of the State of Georgia and the satisfaction of certain
other conditions described in this Agreement.  It is the intention of the

   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

any of its Subsidiaries or by BCG, in each case other than in a fiduciary
capacity or as a result of debts previously contracted, and excluding shares
held by shareholders who perfect their dissenters' rights of appraisal as
provided in Section 3.4 of this Agreement) issued and outstanding at the
Effective Time shall cease to be outstanding and shall be converted into and
exchanged for the right to receive the Merger Consideration.

   3.2  Anti-Dilution Provisions.  In the event BCG or CSBI changes the number
of shares of BCG 

                                       2
<PAGE>
 
Common Stock or CSBI 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
Merger Consideration shall be proportionately adjusted.

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

   3.4  Dissenting Shareholders.  Any holder of shares of BCG Common Stock who
perfects his dissenters' rights of appraisal in accordance with and as
contemplated by Sections 14-2-1301, et seq. of the GBCC shall be entitled to
                                    ------
receive the value of such shares in cash as determined pursuant to such
provision of Law; provided, however, 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 BCG 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
BCG fails to perfect, or effectively withdraws or loses, his right to appraisal
and of payment for his shares, BCG shall issue and deliver the consideration to
which such holder of shares of BCG Common Stock is entitled under this Article 3
(without interest) upon surrender by such holder of the certificate or
certificates representing shares of BCG Common Stock held by him.

   3.5  Fractional Shares.  Notwithstanding any other provision of this
Agreement, each holder of shares of BCG Common Stock exchanged pursuant to the
Merger, who would otherwise have been entitled to receive a fraction of a share
of CSBI 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 CSBI Common Stock multiplied
by the market value of one share of CSBI Common Stock at the Effective Time, in
the case of shares exchanged pursuant to the Merger, or the date of exercise, in
the case of options.  The market value of one share of CSBI Common Stock at the
Effective Time or the date of exercise, as the case may be, shall be the last
sale price of such common stock on NASDAQ (as reported by The Wall Street
Journal or, if not reported thereby, any other authoritative source) on the last

may be.  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  Conversion of Stock Options.

         (a) At the Effective Time, all rights with respect to BCG Common Stock
pursuant to stock options ("BCG Option") granted by BCG under the BCG Key
Employee Stock Option Plan ("BCG Option Plan"), which are outstanding at the
Effective Time, whether or not exercisable, shall be converted into and become
rights with respect to CSBI Common Stock, and CSBI shall assume each BCG Option,
in accordance with the terms of the BCG Option Plan and stock option agreement
by which it is evidenced. From and after the Effective Time, (i) each BCG Option
assumed by CSBI may be exercised solely for shares of CSBI Common stock, (ii)
the number of shares of CSBI Common Stock subject to such BCG Option shall be
equal to the number of shares of BCG Common Stock subject to such BCG Option
immediately prior to the Effective Time multiplied by 1.33, and (iii) the per
share exercise price under each such BCG Option shall be adjusted by dividing
the per share exercise price under each such BCG Option by 1.33 and rounding
down to the nearest cent.

         (b) All restrictions or limitations on transfer with respect to BCG
Common Stock awarded under the BCG Option Plan or any other plan, program, or
arrangement of BCG or BCG Banks, 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 CSBI Common Stock into which such restricted
stock is converted pursuant to Section 3.1 of this Agreement.

                                   ARTICLE 4

                              EXCHANGE OF SHARES

   4.1  Exchange Procedures.  Promptly after the Effective Time, CSBI shall
cause the  exchange agent selected by CSBI (the "Exchange Agent"), to mail to
the former shareholders of BCG appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of BCG Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent).  After
the Effective Time, each holder of shares of BCG Common Stock (other than shares
to be canceled pursuant to Section 3.3 of this Agreement or as to which
dissenters' rights of appraisal have been perfected as provided in Section 3.4
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 BCG 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 CSBI Common Stock to which such holder may be
otherwise entitled (without interest).  CSBI shall not be obligated to deliver
the consideration to which any former holder of BCG Common Stock is entitled as
a result of the Merger until such holder surrenders his certificate or
certificates representing the shares of BCG Common Stock for exchange as
provided in this Section 4.1.  The certificate or certificates of BCG Common
Stock so surrendered shall be duly endorsed as the Exchange Agent may require.
Any other provision of this Agreement notwithstanding, neither CSBI nor the
Exchange Agent shall be liable to a holder of BCG 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 Shareholders.  At the Effective Time, the stock
transfer books of BCG shall be closed as to holders of BCG Common Stock
immediately prior to the Effective Time and no transfer of BCG 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 BCG Common Stock (other than
shares to be canceled pursuant to Sections 3.3 and 3.4 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 shareholders of
record of BCG shall be entitled to vote after the Effective Time at any meeting
of CSBI shareholders the number of whole shares of BCG Common Stock into which
their respective shares of BCG Common  Stock are converted, regardless of
whether such holders have exchanged their certificates representing BCG Common
Stock for certificates representing CSBI Common Stock in accordance with the
provisions of this Agreement.  Whenever a dividend or other distribution is
declared by CSBI on the CSBI 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 CSBI Common Stock as
of any time subsequent to the Effective Time shall be delivered to the holder of
any certificate representing shares of BCG 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
BCG Common Stock certificate, both the CSBI Common Stock certificate (together
with all such undelivered dividends or other distributions without interest) and
any undelivered 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.

                                   ARTICLE 5
                     REPRESENTATIONS AND WARRANTIES OF BCG

   BCG hereby represents and warrants to CSBI as follows:

   5.1  Organization, Standing, and Power. BCG is a corporation duly organized,
validly existing, and in good standing under the Laws of the State of Georgia,
and is duly registered as a bank holding company under the BHC Act. BCG has the
corporate power and authority to carry on its business as now conducted and to
own, lease 

                                       4
<PAGE>
 
and operate its Assets. BCG 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 BCG.

   5.2  Authority, No Breach By Agreement.

         (a) BCG has the corporate power and authority necessary to execute,
deliver and perform its obligations under this Agreement and to consummate the
transaction contemplated hereby.  The execution, delivery and performance of
this Agreement and the consummation of the Merger contemplated herein, have been
duly and validly authorized by all necessary corporate action in respect thereof
on the part of BCG subject to the approval of this Agreement by the holders of a
majority of the outstanding shares of BCG Common Stock. Subject to such
requisite shareholder approval, this Agreement represents a legal, valid, and
binding obligation of BCG, enforceable against BCG in accordance with its terms
(except in all cases as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or similar Laws affecting
the enforcement of creditors' rights generally and except that the availability
of the equitable remedy of specific performance or injunctive relief is subject
to the discretion of the court before which any proceeding may be brought).

         (b) Neither the execution and delivery of this Agreement by BCG, nor
the consummation by BCG of the transaction contemplated hereby, nor compliance
by BCG with any of the provisions hereof, will (i) conflict with or result in a
breach of any provision of BCG's Articles of Incorporation or Bylaws, or (ii)
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 BCG Bank under, any
Contract or Permit of any BCG Bank, where such Default or Lien, or any failure
to obtain such Consent, is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on BCG, or, (iii) subject to receipt of the
requisite approvals referred to in Section 9.1(b) of this Agreement, violate any
Law or Order applicable to any BCG Bank or any of their respective Assets.

         (c) No notice to, filing with, or Consent of, any public body or
authority is necessary for the consummation by BCG of the Merger and the other
transactions contemplated in this Agreement other than (i) in connection or
compliance with the provisions of the Securities Laws, applicable state
corporate and securities Laws, (ii) Consents required from Regulatory
Authorities, (iii) notices to or filings with the IRS or the Pension Benefit
Guaranty Corporation with respect to any employee benefit plans, and (iv)
Consents, filings or notifications which, if not obtained or made, are not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on BCG.

   5.3   Capital Stock.

         (a) The authorized capital stock of BCG consists of 3,000,000 shares of
BCG Common Stock.  At the close of business on March 31, 1997, there were
2,268,097 shares of BCG Common Stock issued and outstanding and 212,915 shares
of BCG Common Stock were reserved for issuance upon the exercise of outstanding
stock options and purchases under the BCG Option Plan.  All of the issued and
outstanding shares of BCG Common Stock are, and all of the shares of CSBI Common
Stock to be issued in exchange for shares of BCG Common Stock upon consummation
of the Merger, when issued in accordance with the terms of this Agreement, will
be, duly and validly issued and outstanding and fully paid and nonassessable
under the GBCC.  None of the outstanding shares of BCG Common Stock has been,
and none of the shares of CSBI Common Stock to be issued in exchange for shares
of BCG Common Stock upon consummation of the Merger will be, issued in violation
of any preemptive rights of the current or past shareholders of BCG.

         (b) Except as set forth in Section 5.3(a) of this Agreement, or as
provided pursuant to the BCG Option Plan, or the Bank Corporation of Georgia

except Liabilities which are accrued or reserved against in the consolidated

BCG Financial Statements or reflected in the notes thereto.  Neither BCG nor
either of the BCG Banks has incurred or paid any Liability since March 31, 1997,

         (a) All tax returns required to be filed by or on behalf of BCG or any

timely filed, granted, and have not expired for periods ended on or before
December 31, 1996, and on or before the date of the most recent fiscal year end
immediately preceding the Effective Time, except to the extent that all such
failures to file, taken together, are not reasonably likely to have a Material
Adverse Effect on BCG, and all returns filed are complete and accurate to the
Knowledge of BCG.  All Taxes shown on filed returns have been paid.  As of the
date of this Agreement, there is no audit examination, deficiency, or refund

Liabilities due with respect to completed and settled examinations or concluded
Litigation have been paid.

         (b) Except as Previously Disclosed, neither BCG nor any of the BCG
Banks 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

<PAGE>
 
the respective BCG Financial Statements has been made and is reflected on such
BCG Financial Statements.

         (d) Deferred Taxes of BCG and the BCG Banks have been provided for in
accordance with GAAP.  Effective January 1, 1993, BCG adopted Financial

         (e) BCG and each BCG Bank has performed all due diligence procedures
required under Internal Revenue Code Section 6722 relating to taxpayer
identification numbers, have complied with all other information reporting
requirements of the IRS, and BCG and each BCG Bank has complied with the
withholding requirements under Internal Revenue Code Section 3406, except for
any nonperformance or noncompliance which, individually or in the aggregate, is
not reasonably likely to have a Material Adverse Effect on either BCG or any BCG
Bank

   5.8  Compliance with Laws.  BCG is duly registered as a bank holding company
under the BHC Act.  Each of the BCG Banks has in effect all permits necessary to
own, lease or operate their Assets and to carry on their respective business as
now conducted, except for those Permits the absence of which are not reasonably
likely to have, individually or in the aggregate, a Material Adverse Effect on
BCG or any of the BCG Banks, and there has occurred no Default under any such
Permit, other than Defaults which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on BCG.  Neither BCG
nor any of the BCG Banks:

         (a) is in violation of any Laws, Orders or Permits applicable to its
business or employees conducting its business, except for violations which are
not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on BCG; and

         (b) except as Previously Disclosed, has received any notification or
communication from any agency or department of federal, state, or local
government or any Regulatory Authority or the staff thereof (i) asserting that
either BCG or any of the BCG Banks are not in compliance with any of the Laws or
Orders which such governmental authority or Regulatory Authority enforces, where
such noncompliance is reasonably likely to have,  individually or in the
aggregate, a Material Adverse Effect on BCG or any of the BCG Banks, (ii)
threatening to revoke any Permits, the revocation of which is reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on either
BCG or any BCG Bank, or (iii) requiring either BCG or any of the BCG Banks to
enter into or consent to the issuance of a cease and desist order, formal
agreement, directive, commitment or memorandum of understanding, or to adopt any
board of directors resolution or similar undertaking, which restricts materially
the conduct of its business, or in any manner relates to its capital adequacy,
its credit or reserve policies, its management, or the payment of dividends.

   5.9  Legal Proceedings.  There is no Litigation instituted or pending, or, to
the Knowledge of BCG, threatened against either BCG or any of the BCG Banks, 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 either
BCG or any of the BCG Banks, nor are there any Orders of any Regulatory
Authorities, other governmental authorities, or arbitrators outstanding against
either BCG or any of the BCG Banks, that are reasonably likely to have,
individually or in the aggregate a Material Adverse Effect on BCG or any of the
BCG Banks.

   5.10  Reports.  Since January 1, 1991, BCG and each of the BCG Banks has
filed all reports and statements, together with any amendments required to be
made with respect thereto, that it was required to file with (i) the SEC,
including, but not limited to, Forms 10-K, Forms 10-Q, Forms 8-K, and proxy
statements, (ii) other Regulatory Authorities, and (iii) any applicable state
securities or banking authorities (except, in the case of state securities
authorities, failures to file which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on either BCG or any
of the BCG Banks).  As of their respective dates, each of such reports and
documents, including the financial statements, exhibits, and schedules thereto,
complied in all material respects with all applicable Laws.  As of their
respective dates, each such report and document did not, in all material
respects, contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
made therein, in light of the circumstances under which they were made, not
misleading.

                                       7
<PAGE>
 
   5.11  Statements True and Correct.  No statement, certificate, instrument or
other writing furnished or to be furnished by either BCG or any of the BCG Banks
or any Affiliate thereof to CSBI pursuant to this Agreement or any other
document, agreement or instrument referred to herein contains or will contain
any untrue statement of material fact or will omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.  None of the information supplied or to be
supplied by either BCG or any of the BCG Banks or any Affiliate thereof for
inclusion in the Registration Statement to be filed by CSBI with the SEC, will,
when the Registration Statement becomes effective, be false or misleading with
respect to any material fact, or omit to state any material fact necessary to
make the statements therein not misleading.  None of the information supplied or
to be supplied by either BCG or any of the BCG Banks or any Affiliate thereof
for inclusion in the Proxy Statement to be mailed to BCG shareholders in
connection with the Shareholders' Meeting, and any other documents to be filed
by either BCG or any of the BCG Banks or any Affiliate thereof with the SEC or
any other Regulatory Authority in connection with the transactions contemplated
hereby, will, at the respective time such documents are filed, and with respect
to the Proxy Statement, when first mailed to the shareholders of BCG, be false
or misleading with respect to any material fact, or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, or, in the case of the Proxy
Statement or any amendment thereof or supplement thereto, at the time of the
Shareholders' Meeting, be false or misleading with respect to any material fact,
or omit to state any material fact necessary to correct any statement in any
earlier communication with respect to the solicitation of any proxy for the
Shareholders' Meeting.  All documents that either BCG or any of the BCG Banks or
any Affiliate thereof is responsible for filing with any Regulatory Authority in
connection with the transactions contemplated hereby will comply as to form in
all material respects with the provisions of applicable Law.

   5.12  Accounting, Tax and Regulatory Matters.  Neither BCG nor any of the BCG
Banks or any Affiliate thereof has taken any action or has any Knowledge of any
fact or circumstance that is reasonably likely to (i) prevent the Merger from
qualifying for pooling-of-interests accounting treatment or as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code, or (ii)
materially impede or delay receipt of any Consents of Regulatory Authorities
referred to in Section 9.1(b) of this Agreement.  To the Knowledge of BCG, there
exists no fact, circumstance, or reason why the requisite Consents referred to
in Section 9.1(b) of this Agreement cannot be received in a timely manner
without the imposition of any condition or restriction of the type described in
the second sentence of such Section 9.1(b).

   5.13  Assets.  Except as Previously Disclosed or as disclosed or reserved
against in the BCG Financial Statements, BCG and each BCG Bank have good and
marketable title, free and clear of all Liens, to all of their respective
Assets.  All material tangible properties used in the business of BCG and each
BCG Bank are in good condition, reasonable wear and tear excepted, and are
usable in the ordinary course of business consistent with BCG's past practices.
All Assets which are material to BCG's and BCG Banks' businesses held under
leases or subleases by BCG or any of the BCG Banks, are held under valid
Contracts enforceable in accordance with their respective terms (except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or other Laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceedings may be brought), and each such
Contract is in full force and effect.  The policies of fire, theft, liability,
and other insurance maintained with respect to the Assets or businesses of BCG
and the BCG Banks provide adequate coverage under current industry practices
against loss or Liability, and the fidelity and blanket bonds in effect as to
which BCG or any of the BCG Banks is a named insured are reasonably sufficient.
The Assets of BCG and the BCG Banks include all assets required to operate the
business of BCG and the BCG Banks as presently conducted.

   5.14  Environmental Matters.

         (a) To the Knowledge of BCG, BCG and BCG Banks' Participation
Facilities, and their respective Loan Properties are, and have been, in
substantial compliance with all Environmental Laws, except for violations which
are not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on BCG or any of the BCG Banks.

                                       8
<PAGE>
 
         (b) There is no Litigation pending or, to the Knowledge of BCG,
threatened before any court, governmental agency or authority or other forum in
which either BCG, BCG Banks or any of their respective Participation Facilities
have been or, with respect to threatened Litigation, may be named as a defendant
(i) for alleged noncompliance (including by any predecessor) with any
Environmental Law or (ii) relating to the release into the environment of any
Hazardous Material (as defined below) or oil, whether or not occurring at, on,
under or involving a site owned, leased or operated by either BCG, BCG Banks or
any of their respective Participation Facilities, except for such Litigation
pending or threatened that is not reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on BCG.

         (c) There is no Litigation pending or, to the Knowledge of BCG,
threatened before any court, governmental agency or board or other forum in
which any of their respective Loan Properties (or any BCG Bank in respect of
such Loan Property) has been or, with respect to threatened Litigation, may be
named as a defendant or potentially responsible party (i) for alleged
noncompliance (including by any predecessor) with any Environmental Law or (ii)
relating to the release into the environment of any Hazardous Material or oil,
whether or not occurring at, on, under or involving a Loan Property, except for
such Litigation pending or threatened that is not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on either BCG or any
of the BCG Banks.

         (d) To the Knowledge of BCG, there is no reasonable basis for any
Litigation of a type described in subsections (b) or (c), except such as is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on either BCG or any of the BCG Banks.

         (e) To the Knowledge of BCG, there have been no releases of Hazardous
Material or oil in, on, under or affecting any Participation Facility or Loan
Property, except such as are not reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on either BCG or any of the BCG Banks.

         (f) Notwithstanding the foregoing, with respect to any of the BCG
Banks' Loan Properties, BCG has not conducted any independent investigation and
is making these representations and warranties only with respect to its
Knowledge.

   5.15  Employee Benefit Plans.

         (a) BCG has Previously Disclosed, and delivered or made available to
CSBI 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
plan, 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 BCG or any Affiliate thereof for the benefit of employees,
retirees, dependents, spouses, directors, independent contractors, or other
beneficiaries and under which such persons are eligible to participate
(collectively, the  "BCG Benefit Plans").  Any of the BCG 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 "BCG ERISA Plan."  Each BCG ERISA Plan which
is also a "defined benefit plan" (as defined in Section 414(j) of the Internal
Revenue Code) is referred to herein as a "BCG Pension Plan".  No BCG Pension
Plan is or has been a multi-employer plan within the meaning of Section 3(37) of
ERISA.

         (b) All BCG 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 BCG.  Each BCG
ERISA Plan which is intended to be qualified under Section 401(a) of the
Internal Revenue Code has received a favorable determination letter from the
IRS, and BCG is not aware of any circumstances likely to result in revocation of
any such favorable determination letter.  BCG has not engaged in a transaction
with respect to any BCG Benefit Plan that, assuming the taxable period of such
transaction expired as of the date hereof, would subject any BCG Companies to a
tax or penalty imposed by either Section 4975 of the Internal Revenue Code or

                                       9
<PAGE>
 
Section 502(i) or ERISA in amounts which are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on BCG.

         (c) No BCG ERISA Plan which is a defined benefit plan has any "unfunded
current liability," as that term is defined in Section 302(d)(8)(A) of ERISA,
based on actuarial assumptions set forth for such plan's most recent actuarial
valuation, and the fair market value of the assets of any such plan exceeds the
plan's "benefit liabilities," as that term is defined in Section 4001(a)(16) of
ERISA, when determined under actuarial factors that would apply if the plan
terminated in accordance with all applicable legal requirements.  Since the date
of the most recent actuarial valuation, there has been (i) no material change in
the financial position of any BCG Pension Plan, (ii) no change in the actuarial
assumptions with respect to any BCG Pension Plan, and (iii) no increase in
benefits under any BCG Pension Plan as a result of plan amendments or changes in
applicable Law  which is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on BCG or materially affect the funding
status of any such plan.  Neither any BCG Pension Plan nor any "single-employer
plan", within the meaning of Section 4001(a)(15) of ERISA, currently or formerly
maintained by BCG, or the single-employer plan of any entity which is considered
one employer with BCG under Section 4001 of ERISA or Section 414 of the Internal
Revenue Code or Section 302 of ERISA (whether or not waived) (an "ERISA
Affiliate") has an "accumulated funding deficiency" within the meaning of
Section 412 of the Internal Revenue Code or Section 302 of ERISA, which is
reasonably likely to have a Material Adverse Effect on BCG.  BCG has not
provided, and is not required to provide, security to a BCG Pension Plan or to
any single-employer plan of an ERISA Affiliate pursuant to Section 401(a)(29) of
the Internal Revenue Code.

         (d) Within the six-year period preceding the Effective Time, no
Liability under Subtitle C or D of Title IV of ERISA has been or is expected to
be incurred by BCG with respect to any ongoing, frozen or terminated single-
employer plan or the single-employer plan of any ERISA Affiliate, which
Liability is reasonably likely to have a Material Adverse Effect on BCG. Except
as Previously Disclosed, BCG has not incurred any withdrawal Liability with
respect to a multi employer plan under Subtitle B of Title IV or ERISA
(regardless of whether based on contributions of an ERISA Affiliate), which
Liability is reasonably likely to have a Material Adverse Effect on BCG.  No
notice of a "reportable event", within the meaning of Section 4043 of ERISA for
which the 30-day reporting requirement has not been waived, has been required to
be filed for any BCG Pension Plan or by any ERISA Affiliate within the 12-month
period ending on the date hereof.

         (e) Except as Previously Disclosed, BCG has no obligations to provide
health and life benefits under any of the BCG Benefit Plans after termination of
employment, except as required by Section 601 of ERISA and Section 4980 B of the
Internal Revenue Code and BCG retains the right to amend or terminate any such
Plan.

         (f) Except as Previously Disclosed, neither the execution and delivery
of this Agreement nor the consummation of the transactions contemplated hereby
will (i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute or otherwise) becoming due to any
officer, director or any employee of BCG from BCG under any BCG Benefit Plan or
otherwise, (ii) increase any benefits otherwise payable under any BCG Benefit
Plan, or (iii) result in any acceleration of the time of payment or vesting of
any such benefit.

         (g) 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 BCG and its 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 fully reflected on the BCG Financial Statements to the extent required
by and in accordance with GAAP.

   5.16  Material Contracts.  Except as Previously Disclosed or otherwise
reflected in the BCG Financial Statements, neither BCG, any of the BCG Banks nor
any of their respective Assets, businesses or operations, is a party to, or is
bound or affected by, or receives benefits under, (i) any employment, severance,
termination, consulting or retirement Contract providing for aggregate payments
to any Person in any calendar year in excess of $100,000, and (ii) any Contract
relating to the borrowing of money by BCG, any of the BCG Banks or the guarantee
by BCG or any of the BCG Banks of any such obligation (other than Contracts
evidencing deposit liabilities, purchases of federal funds, fully-secured

                                       10
<PAGE>
 
repurchase agreements, trade payables, and Contracts relating to borrowings or
guarantees made in the ordinary course of business) (together with all Contracts
referred to in Sections 5.13 and 5.15(a) of this Agreement, the "BCG
Contracts"). Neither BCG nor any of the BCG Banks is in Default under any BCG
Contract, other than Defaults which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on either BCG or any
of the BCG Banks.  All of the indebtedness of BCG and the BCG Banks for money
borrowed is prepayable at any time by BCG without penalty or premium.

   5.17  State Takeover Laws.  BCG has not taken any necessary action which
would require the transaction contemplated by this Agreement to comply with any
applicable state takeover Law.

   5.18  Continuity of Stock Ownership.

         (a) To the Knowledge of BCG, there is no plan or intention by the
holders of BCG Shares to sell, exchange, or otherwise dispose of a number of
CSBI Shares received in the Merger that would reduce the ownership of CSBI
Shares by the holders of BCG Shares to a number of CSBI Shares having a value,
as of the date of the Merger, of less than fifty percent (50%) of the value of
all the formerly outstanding BCG Shares as of the same date.  For purposes of
this representation, CSBI Shares Exchanged for cash pursuant to Section 1.5,
surrendered by dissenters or exchanged for cash in lieu of fractional CSBI
Shares will be treated as outstanding on the date of the Merger.  Moreover, BCG
Shares and CSBI Shares held by holders of BCG Shares and otherwise sold,
redeemed, or disposed of prior or subsequent to the Merger will be considered in
making this representation;

         (b) CSBI will acquire at least ninety percent (90%) of the fair market
value of the net Assets and at least seventy percent (70%) of the fair market
value of the gross assets held by BCG immediately prior to the transaction. For
purposes of this representation, amounts paid by BCG to dissenters, BCG assets
used to pay its Merger expenses, and all redemptions and distributions (except
for regular, normal dividends) made by BCG immediately preceding the Merger,
will be included as assets of BCG held immediately prior to the Merger; and

         (c) The liabilities of BCG to be assumed by CSBI by virtue of the
Merger and the liabilities to which the Assets of BCG are subject were incurred
by BCG in the ordinary course of business.


                                   ARTICLE 6

                    REPRESENTATIONS AND WARRANTIES OF CSBI

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

qualified or licensed is not reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on CSBI.

   6.2  Authority, No Breach By Agreement.

         (a) CSBI has the corporate power and authority necessary to execute,
deliver and perform its obligations under this Agreement and to consummate the
transaction contemplated hereby.  The execution, delivery and performance of

duly and validly authorized by all necessary corporate action in respect thereof
on the part of CSBI.  This Agreement represents a legal, valid, and binding
obligation of CSBI, enforceable against CSBI in accordance with its terms
(except in all cases as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or similar Laws affecting
the enforcement of creditors' rights generally and except that the availability
of the equitable remedy of specific performance or injunctive relief is subject

                                       11
<PAGE>
 
to the discretion of the court before which any proceeding may be brought).

         (b) Neither the execution and delivery of this Agreement by CSBI, nor
the consummation by CSBI of the transaction contemplated hereby, nor compliance
by CSBI with any of the provisions hereof, will (i) conflict with or result in a
breach of any provision of CSBI's Articles of Incorporation or Bylaws, or (ii)
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 CSBI Companies under, any
Contract or Permit of any CSBI Companies, where such Default or Lien, or any
failure to obtain such Consent, is reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on CSBI, or, (iii) subject to receipt
of the requisite approvals referred to in Section 9.1(b) of this Agreement,
violate any Law or Order applicable to any CSBI Companies or any of their
respective Assets.

         (c) No notice to, filing with, or Consent of, any public body or
authority is necessary for the consummation by CSBI of the Merger and the other
transactions contemplated in this Agreement other than (i) in connection or

corporate and securities Laws, (ii) Consents required from Regulatory
Authorities, (iii) notices to or filings with the IRS or the Pension Benefit
Guaranty Corporation with respect to any employee benefit plans, and (iv)
Consents, filings or notifications which, if not obtained or made, are not

Effect on CSBI.

   6.3   Capital Stock.

         (a) The authorized capital stock of CSBI consists of 15,000,000 shares
of CSBI Common Stock.  At the close of business on March 31, 1997, there were
7,761,624 shares of CSBI Common Stock issued and outstanding.  As of March 31,
1997, 50,000 shares of CSBI Common Stock were reserved for issuance upon the

the Century South Banks, Inc. Employee Stock Ownership Plan ("CSBI ESOP"), and
5,000 shares were reserved pursuant to options granted to certain executive

of CSBI Common Stock are, and all of the shares of CSBI Common Stock to be
issued in exchange for shares of BCG Common Stock upon consummation of the
Merger, when issued in accordance with the terms of this Agreement, will be,
duly and validly issued and outstanding and fully paid and nonassessable under
the GBCC.  None of the outstanding shares of CSBI Common Stock has been, and
none of the shares of CSBI Common Stock to be issued in exchange for shares of
BCG Common Stock upon consummation of the Merger will be, issued in violation of
any preemptive rights of the current or past shareholders of CSBI.

         (b) Except as set forth in Section 6.3(a) of this Agreement, or as

timely filed, granted, and have not expired for periods ended on or before
December 31, 1996, and on or before the date of the most recent fiscal year end
immediately preceding the Effective Time, except to the extent that all such
failures to file, taken together, are not reasonably likely to have a Material
Adverse Effect on CSBI, and all returns filed are complete and accurate to the
Knowledge of CSBI.  All Taxes shown on filed returns have been paid.  As of the

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 CSBI

not reasonably likely to have a Material Adverse Effect on the CSBI Companies.

   6.8  Compliance with Laws.  CSBI is duly registered as a bank holding company
under the BHC Act.  Each of the CSBI Companies has in effect all permits
necessary to own, lease or operate their Assets and to carry on their business
as now conducted, except for those Permits the absence of which are not
reasonably likely to have, individually or in the aggregate, a Material Adverse

                                       13
<PAGE>
 
Effect on CSBI, and there has occurred no Default under any such Permit, other

aggregate, a Material Adverse Effect on CSBI.  None of the CSBI Companies:

         (a) is in violation of any Laws, Orders or Permits applicable to its
business or employees conducting its business, except for violations which are
not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on CSBI; and

government or any Regulatory Authority or the staff thereof (i) asserting that

which such governmental authority or Regulatory Authority enforces, where such
noncompliance is reasonably likely to have,  individually or in the aggregate, a
Material Adverse Effect on CSBI, (ii) threatening to revoke any Permits, the
revocation of which is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on CSBI, or (iii) requiring any CSBI
Companies to enter into or consent to the issuance of a cease and desist order,
formal agreement, directive, commitment or memorandum of understanding, or to
adopt any Board resolution or similar undertaking, which restricts materially
the conduct of its business, or in any manner relates to its capital adequacy,
its credit or reserve policies, its management, or the payment of dividends.

   6.9  Legal Proceedings.  There is no Litigation instituted or pending, or, to
the Knowledge of CSBI, threatened against any CSBI Companies, 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 CSBI, nor are
there any Orders of any Regulatory Authorities, other governmental authorities,
or arbitrators outstanding against any CSBI Companies, that are reasonably
likely to have, individually or in the aggregate a Material Adverse Effect on
CSBI.

   6.10  Reports.  Since January 1, 1991, each of the CSBI Companies has filed
all reports and statements, together with any amendments required to be made
with respect thereto, that it was required to file with (i) the SEC, including,
but not limited to, Forms 10-K, Forms 10-Q, Forms 8-K, and proxy statements,
(ii) other Regulatory Authorities, and (iii) any applicable state securities or
banking authorities (except, in the case of state securities authorities,

aggregate, a Material Adverse Effect on CSBI).  As of their respective dates,
each of such reports and documents, including the financial statements,
exhibits, and schedules thereto, complied in all material respects with all
applicable Laws.  As of their respective dates, each such report and document
did not, in all material respects, contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements made therein, in light of the circumstances under which
they were made, not misleading.

   6.11  Statements True and Correct.  No statement, certificate, instrument or
other writing furnished or to be furnished by any CSBI Companies or any
Affiliate thereof to BCG pursuant to this Agreement or any other document,
agreement or instrument referred to herein contains or will contain any untrue
statement of material fact or will omit to state a material fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.  None of the information supplied or to be supplied by any
CSBI Companies or any Affiliate thereof for inclusion in the Registration
Statement to be filed by CSBI with the SEC, will, when the Registration
Statement becomes effective, be false or misleading with respect to any material
fact, or omit to state any material fact necessary to make the statements
therein not misleading.  None of the information supplied or to be supplied by
any CSBI Companies or any Affiliate thereof for inclusion in the Proxy Statement

   6.12  Accounting, Tax and Regulatory Matters.  No CSBI Company or any
Affiliate thereof has taken any action or has any Knowledge of any fact or
circumstance that is reasonably likely to (i) prevent the Merger from qualifying
for pooling-of-interests accounting treatment or as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, or (ii) materially
impede or delay receipt of any Consents of Regulatory Authorities referred to in
Section 9.1(b) of this Agreement.  To the Knowledge of CSBI, there exists no
fact, circumstance, or reason why the requisite Consents referred to in Section
9.1(b) of this Agreement cannot be received in a timely manner without the
imposition of any condition or restriction of the type described in the second
sentence of such Section 9.1(b).

   6.13  Assets.  Except as Previously Disclosed or as disclosed or reserved
against in the CSBI Financial Statements, CSBI and each CSBI Subsidiary have
good and marketable title, free and clear of all Liens, to all of their
respective Assets.  All material tangible properties used in the business of
CSBI and each CSBI Subsidiary are in good condition, reasonable wear and tear
excepted, and are usable in the ordinary course of business consistent with
CSBI's past practices.  All Assets which are material to CSBI and CSBI
Subsidiaries= businesses held under leases or subleases by CSBI or any of the
CSBI Subsidiaries, are held under valid Contracts enforceable in accordance with
their respective terms (except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or other Laws affecting the
enforcement of creditors' rights generally and except that the availability of
the equitable remedy of specific performance or injunctive relief is subject to
the discretion of the court before which any proceedings may be brought), and
each such Contract is in full force and effect.  The policies of fire, theft,
liability, and other insurance maintained with respect to the Assets or
businesses of CSBI and the CSBI Subsidiaries provide adequate coverage under
current industry practices against loss or Liability, and the fidelity and
blanket bonds in effect as to which CSBI or any of the CSBI Subsidiaries is a
named insured are reasonably sufficient.  The Assets of CSBI and the CSBI
Subsidiaries include all assets required to operate the business of CSBI and the
CSBI Subsidiaries as presently conducted.

   6.14  Environmental Matters.

         (a) To the Knowledge of CSBI, CSBI and CSBI Subsidiaries= Participation
Facilities, and their respective Loan Properties are, and have been, in
substantial compliance with all Environmental Laws, except for violations which
are not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on CSBI or any of the CSBI Subsidiaries.

         (b) There is no Litigation pending or, to the Knowledge of CSBI,
threatened before any court, governmental agency or authority or other forum in
which either CSBI, CSBI Subsidiaries or any of their respective Participation
Facilities have been or, with respect to threatened Litigation, may be named as
a defendant (i) for alleged noncompliance (including by any predecessor) with
any Environmental Law or (ii) relating to the release into the environment of
any Hazardous Material (as defined below) or oil, whether or not occurring at,
on, under or involving a site owned, leased or operated by either CSBI, CSBI
Subsidiaries or any of their respective Participation Facilities, except for
such Litigation pending or threatened that is not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on CSBI.

         (c) There is no Litigation pending or, to the Knowledge of CSBI,
threatened before any court, governmental agency or board or other forum in
which any of their respective Loan Properties (or any CSBI Subsidiaries in
respect of such Loan Property) has been or, with respect to threatened
Litigation, may be named as a defendant or potentially responsible party (i) for
alleged noncompliance (including by any predecessor) with any Environmental Law
or (ii) relating to the release into the environment of any Hazardous Material
or oil, whether or not occurring at, on, under or involving a Loan Property,
except for such Litigation pending or threatened that is not reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on either
CSBI or any of the CSBI Subsidiaries.

         (d) To the Knowledge of CSBI, there is no reasonable basis for any
Litigation of a type described in subsections (b) or (c), except such as is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on either CSBI or any of the CSBI Subsidiaries.

                                       15
<PAGE>
 
         (e) To the Knowledge of CSBI, there have been no releases of Hazardous
Material or oil in, on, under or affecting any Participation Facility or Loan
Property, except such as are not reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on either CSBI or any of the CSBI
Subsidiaries.

         (f) Notwithstanding the foregoing, with respect to any of the CSBI
Subsidiaries= Loan Properties, CSBI has not conducted any independent
investigation and is making these representations and warranties only with
respect to its Knowledge.

   6.15  Employee Benefit Plans.

         (a) CSBI has Previously Disclosed, and delivered or made available to
BCG 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
plan, 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 CSBI or any Affiliate thereof for the benefit of employees,
retirees, dependents, spouses, directors, independent contractors, or other
beneficiaries and under which such persons are eligible to participate
(collectively, the  "CSBI Benefit Plans").  Any of the CSBI 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 "CSBI ERISA Plan."  Each CSBI ERISA Plan
which is also a "defined benefit plan" (as defined in Section 414(j) of the
Internal Revenue Code) is referred to herein as a "CSBI Pension Plan".  No CSBI
Pension Plan is or has been a multi-employer plan within the meaning of Section
3(37) of ERISA.

         (b) All CSBI 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 CSBI.  Each CSBI
ERISA Plan which is intended to be qualified under Section 401(a) of the
Internal Revenue Code has received a favorable determination letter from the
IRS, and CSBI is not aware of any circumstances likely to result in revocation
of any such favorable determination letter. CSBI has not engaged in a
transaction with respect to any CSBI Benefit Plan that, assuming the taxable
period of such transaction expired as of the date hereof, would subject any CSBI
Companies to a tax or penalty imposed by either Section 4975 of the Internal
Revenue Code or Section 502(i) or ERISA in amounts which are reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on CSBI.

         (c) No CSBI ERISA Plan which is a defined benefit plan has any
"unfunded current liability," as that term is defined in Section 302(d)(8)(A) of
ERISA, based on actuarial assumptions set forth for such plan's most recent
actuarial valuation, and the fair market value of the assets of any such plan
exceeds the plan's "benefit liabilities," as that term is defined in Section
4001(a)(16) of ERISA, when determined under actuarial factors that would apply
if the plan terminated in accordance with all applicable legal requirements.
Since the date of the most recent actuarial valuation, there has been (i) no
material change in the financial position of any CSBI Pension Plan, (ii) no
change in the actuarial assumptions with respect to any CSBI Pension Plan, and
(iii) no increase in benefits under any CSBI Pension Plan as a result of plan
amendments or changes in applicable Law  which is reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on CSBI or
materially affect the funding status of any such plan.  Neither any CSBI Pension
Plan nor any "single-employer plan", within the meaning of Section 4001(a)(15)
of ERISA, currently or formerly maintained by CSBI, or the single-employer plan
of any entity which is considered one employer with CSBI under Section 4001 of
ERISA or Section 414 of the Internal Revenue Code or Section 302 of ERISA
(whether or not waived) (an "ERISA Affiliate") has an "accumulated funding
deficiency" within the meaning of Section 412 of the Internal Revenue Code or
Section 302 of ERISA, which is reasonably likely to have a Material Adverse
Effect on CSBI.  CSBI has not provided, and is not required to provide, security
to a CSBI Pension Plan or to any single-employer plan of an ERISA Affiliate
pursuant to Section 401(a)(29) of the Internal Revenue Code.

                                       16
<PAGE>
 
         (d) Within the six-year period preceding the Effective Time, no
Liability under Subtitle C or D of Title IV of ERISA has been or is expected to
be incurred by CSBI with respect to any ongoing, frozen or terminated single-
employer plan or the single-employer plan of any ERISA Affiliate, which
Liability is reasonably likely to have a Material Adverse Effect on CSBI. Except
as Previously Disclosed, CSBI has not incurred any withdrawal Liability with
respect to a multi employer plan under Subtitle B of Title IV or ERISA
(regardless of whether based on contributions of an ERISA Affiliate), which
Liability is reasonably likely to have a Material Adverse Effect on CSBI.  No
notice of a "reportable event", within the meaning of Section 4043 of ERISA for
which the 30-day reporting requirement has not been waived, has been required to
be filed for any CSBI Pension Plan or by any ERISA Affiliate within the 12-month
period ending on the date hereof.

         (e) Except as Previously Disclosed, CSBI has no obligations to provide
health and life benefits under any of the CSBI Benefit Plans after termination
of employment, except as required by Section 601 of ERISA and Section 4980 B of
the Internal Revenue Code, CSBI retains the right to amend or terminate any such
Plan.

         (f) Except as Previously Disclosed, neither the execution and delivery
of this Agreement nor the consummation of the transactions contemplated hereby
will (i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute or otherwise) becoming due to any
officer, director or any employee of CSBI from CSBI under any CSBI Benefit Plan
or otherwise, (ii) increase any benefits otherwise payable under any CSBI
Benefit Plan, or (iii) result in any acceleration of the time of payment or
vesting of any such benefit.

         (g) 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 CSBI and its 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 fully reflected on the CSBI Financial Statements to the extent
required by and in accordance with GAAP.

   6.16  Material Contracts.  Except as Previously Disclosed or otherwise
reflected in the CSBI Financial Statements, neither CSBI, any of the CSBI
Subsidiaries nor any of their respective Assets, businesses or operations, is a
party to, or is bound or affected by, or receives benefits under, (i) any
employment, severance, termination, consulting or retirement Contract providing
for aggregate payments to any Person in any calendar year in excess of $100,000,
and (ii) any Contract relating to the borrowing of money by CSBI, any of the
CSBI Subsidiaries or the guarantee by CSBI or any of the CSBI Subsidiaries of
any such obligation (other than Contracts evidencing deposit liabilities,
purchases of federal funds, fully-secured repurchase agreements, trade payables,
and Contracts relating to borrowings or guarantees made in the ordinary course
of business) (together with all Contracts referred to in Sections 6.13 and
6.15(a) of this Agreement, the "CSBI Contracts"). Neither CSBI nor any of the
CSBI Subsidiaries is in Default under any CSBI Contract, other than Defaults
which are not reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on either CSBI or any of the CSBI Subsidiaries.  All of
the indebtedness of CSBI and the CSBI Subsidiaries for money borrowed is
prepayable at any time by CSBI without penalty or premium.

Stock upon consummation of the Merger.  BCG shall furnish all information
concerning it and the holders of its capital stock as CSBI may reasonably
request in connection with such action.  BCG shall call a Shareholders' Meeting,
to be held as soon as reasonably practicable after the Registration Statement is
declared effective by the SEC, for the purpose of voting upon approval of this
Agreement and such other related matters as it deems appropriate.  In connection

BCG to review such applications prior to filing same.

   8.3  Filings with State Offices.  Upon the terms and subject to the
conditions of this Agreement, CSBI shall execute and file the Articles of Merger
with the Secretary of State of the State of Georgia in connection with the
Closing.

conditions of this Agreement, each Party agrees to use its reasonable efforts to
take all actions, and to do all things necessary, proper, or advisable under
applicable Laws, as promptly as practicable so as to permit consummation of the
Merger at the earliest possible date and to otherwise enable consummation of the
transactions contemplated hereby and shall cooperate fully with the other Party
hereto to that end (it being understood that any amendments to the Registration
Statement filed by CSBI in connection with the CSBI Common Stock to be issued in
the Merger or a resolicitation of proxies as a consequence of an acquisition
agreement by CSBI or any of its Subsidiaries shall not violate this covenant),
including, without limitation, using its reasonable efforts to lift or rescind
any Order adversely affecting its ability to consummate the transactions
contemplated herein and to cause to be satisfied the conditions referred to in
Article 9 of this Agreement.  Each Party shall use its reasonable efforts to
obtain all Consents necessary or desirable for the consummation of the
transactions contemplated by this Agreement.

   8.5  Investigation and Confidentiality.

advised of all material developments relevant to its business and to
consummation of the Merger and shall permit the other Party to make or cause to

Subsidiaries and of their respective financial and legal conditions as the other

related to the transaction contemplated hereby and shall not interfere
unnecessarily with normal operations.  No investigation by a Party shall affect
the representations and warranties of the other Party.

<PAGE>
 
         (b) Each Party shall, and shall cause its advisers and agents to,

financial condition except in furtherance of the transaction contemplated by
this Agreement.  If this Agreement is terminated prior to the Effective Time,
each Party shall promptly return all documents and copies thereof, and all work
papers containing confidential information received from the other Party.

         (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, BCG and CSBI shall consult
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.

   8.7  Certain Actions.  Except with respect to this Agreement and the
transactions contemplated hereby or with the consent of the other Party, neither
Party nor any of its respective Affiliate, nor any investment banker, attorney,
accountant or other representative (collectively "Representatives") retained by
such Party 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, neither Party nor any of its
respective Affiliates or Representatives 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
either Party may communicate information about such an Acquisition Proposal to
its stockholders if and to the extent that it is required to do so in order to
comply with its legal obligations as advised by counsel. Either Party shall
promptly notify the other verbally and in writing in the event that such Party
receives any inquiry or proposal relating to any such transaction.  Each Party
shall (i) immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any Persons conducted heretofore with respect
to any of the foregoing, and (ii) direct and use its reasonable efforts to cause
all of its Representatives not to engage in any of the foregoing.

   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 pooling-of-interests accounting
treatment and treatment as a "reorganization" within the meaning of Section
368(a) of the Internal Revenue Code for federal income tax purposes.

   8.9  State Takeover Laws.  BCG shall take all necessary steps to exempt the
transactions contemplated by this Agreement from, or if necessary challenge the
validity or applicability of, any applicable state takeover Law.

   8.10  Articles of Incorporation Provisions.  BCG shall take all necessary
action to ensure that the entering into of this Agreement and the consummation
of the Merger does not and will not result in the grant of any rights to any
Person under the Articles of Incorporation, Bylaws or other governing
instruments of BCG or restrict or impair the ability of CSBI to vote, or
otherwise to exercise the rights of a shareholder with respect to, shares of BCG
that may be acquired or controlled by it.

   8.11  Agreement of Affiliates.  BCG has Previously Disclosed all Persons whom
it reasonably believes is an "affiliate" of BCG for purposes of Rule 145 under
the 1933 Act.  BCG shall use its reasonable efforts to cause each such Person to
deliver to CSBI not later than 30 days after the date of this Agreement, a
written agreement, substantially in the form of Exhibit 1, providing that such
Person will not sell, pledge, transfer, or otherwise dispose of the shares of
BCG Common Stock held by such Person except as contemplated by such agreement or
by this Agreement and will not sell, pledge, transfer, or otherwise dispose of
the shares of CSBI Common Stock to be received by such Person upon consummation
of the Merger except in compliance with applicable provisions of the 1933 Act

                                       22
<PAGE>
 
and the rules and regulations thereunder and until such time as the financial
results covering at least 30 days of combined operations of CSBI and BCG have
been published within the meaning of Section 201.01 of the SEC's Codification of
Financial Reporting Policies.  If the Merger will qualify for pooling-of-
interests accounting treatment, shares of CSBI Common Stock issued to such
affiliates of BCG in exchange for shares of BCG Common Stock shall not be
transferable until such time as financial results referred to in this Section
8.11 have been published as set forth in this Section 8.11, regardless of
whether each such affiliate has provided the written agreement referred to in
this Section 8.11 (and CSBI shall be entitled to place restrictive legends upon
certificates for shares of CSBI Common Stock issued to affiliates of BCG
pursuant to this Agreement to enforce the provisions of this Section 8.11).
CSBI shall not be required to maintain the effectiveness of the Registration
Statement under the 1933 Act for the purposes of resale of CSBI Common Stock by
such affiliates.

   8.12  Employee Benefits and Contracts.  Following the Effective Time, CSBI
shall provide generally to officers and employees of BCG employee benefits under
employee benefit plans on terms and conditions which when taken as a whole are
substantially similar to those currently provided by the CSBI Companies to their
similarly situated officers and employees.  For purposes of  participation and
vesting under such employee benefit plans, the service of the employees of BCG
prior to the Effective Time shall be treated as service with the CSBI Companies
participating in such employee benefit plans. Except as set forth herein, CSBI
also shall honor in accordance with their terms all employment, severance,
consulting and other compensation Contracts Previously Disclosed to CSBI between
BCG and any current or former director, officer, or employee thereof, and all
provisions for vested benefits or other vested amounts earned or accrued through
the Effective Time under the BCG Benefit Plans. Each Party will exercise its
best efforts to amend any agreement it has with its respective officers and
employees to except the Merger from qualifying under any change of control
provision under such officer's or employee's  employment, option or similar
agreement

Century South Banks, Inc.
455 Jesse Jewell Parkway, Suite 301
Gainesville, Georgia 30501

Attention: James A. Faulkner, President

Gentlemen:

   The undersigned is a shareholder of Bank Corporation of Georgia  ("BCG"), a
bank holding company organized under the laws of the State of Georgia and
located in Macon, Georgia, and will become a shareholder of Century South Banks,
Inc.("CSBI") pursuant to the transaction described in the Agreement and Plan of
Merger, dated as of March 31, 1997 (the "Agreement"), by and between BCG and
CSBI.  Under the terms of the Agreement, BCG will be merged with and into CSBI
(the "Merger"), and the shares of the $1.00 par value common stock of BCG will
be converted into and exchanged for shares of the $1.00 par value common stock
of CSBI ("CSBI Common Stock").  This Affiliate Agreement represents an agreement
between the undersigned and CSBI regarding certain rights and obligations of the
undersigned in connection with the shares of CSBI to be received by the
undersigned as a result of the Merger.

   In consideration of the Merger and the mutual covenants contained herein, the
undersigned and CSBI hereby agree as follows:

   1.  Affiliate Status.  The undersigned understands and agrees that as to BCG
he is an "affiliate" under Rule 145(c) as defined in Rule 405 of the Rules and
Regulations of the Securities and Exchange Commission ("SEC") under the
Securities Act of 1933, as amended ("1933 Act"), and the undersigned anticipates
that he will be such an "affiliate" at the time of the Merger.

   2.  Initial Restriction on Disposition.  The undersigned agrees that he will
not sell, transfer, or otherwise dispose of his interest in, or reduce his risk
relative to, any of the shares of CSBI Common Stock into which his shares of BCG
Common Stock are converted upon consummation of the Merger until such time as
CSBI notifies the undersigned that the requirements of SEC Accounting Series
Release Nos. 130 and 135 ("ASR 130 and 135") have been met.  The undersigned
understands that ASR 130 and 135 relate to publication of financial results of
post-Merger combined operations of CSBI and BCG. CSBI agrees that it will
publish such results within 45 days after the end of the most recent calendar
quarter of CSBI containing the required period of post-Merger combined
operations and that it will notify the undersigned promptly following such
publication.

   3.  Covenants and Warranties of Undersigned.  The undersigned represents,
warrants and agrees that:

         (a) The CSBI Common Stock received by the undersigned as a result of
the Merger will be taken for his own account and not for others, directly, or
indirectly, in whole or in part.

         (b) CSBI has informed the undersigned that any distribution by the
undersigned of CSBI Common Stock has not been registered under the 1933 Act and
that shares of CSBI Common Stock received pursuant to the Merger can only be
sold by the undersigned (1) following registration under the 1933 Act, or (2) in
conformity with the volume and other requirements of Rule 145(d) promulgated by
the SEC as the same now exist or may hereafter be amended, or (3) to the extent
some other exemption from registration under the 1933 Act might be available.
THE UNDERSIGNED UNDERSTANDS THAT CSBI IS UNDER NO OBLIGATION TO FILE A
REGISTRATION STATEMENT WITH THE SEC COVERING THE DISPOSITION OF THE
UNDERSIGNED'S SHARES OF CSBI COMMON STOCK.

   4.  Restrictions on Transfer.  The undersigned understands and agrees that
stop transfer instructions with respect to the shares of CSBI Common Stock
received by the undersigned pursuant to the Merger will be given to CSBI's
Transfer Agent and that there will be placed on the certificates for such
shares, or shares issued in substitution thereof, a legend stating in substance:

                                       36
<PAGE>
 
         "The shares represented by this certificate were issued pursuant to a
         business combination and may not be sold nor may the owner thereof
         reduce his risks relative thereto in any way, until such time as CSBI
         has published the financial results covering at least 30 days of
         combined operations after the effective date of the Merger through
         which the business combination was effected.  In addition, the shares
         represented by this certificate may not be sold, transferred or
         otherwise disposed of except or unless (1) covered by an effective
         registration statement under the Securities Act of 1933, as amended,
         (2) in accordance with (i) rule 145(d) (in the case of shares issued to
         an individual who is not an affiliate of CSBI) or (ii) Rule 144 (in the
                              ---
         case of shares issued to an individual who is an affiliate of CSBI) of
         the Rules and Regulations of such Act, or (3) in accordance with a
         legal opinion satisfactory to counsel for CSBI that such sale or
         transfer is otherwise exempt from the registration requirements of the
         Act."

Such legend will also be placed on any certificate representing CSBI securities
issued subsequent to the original issuance of the CSBI Common Stock pursuant to
the Merger as a result of any stock dividend, stock split, or other
recapitalization as long as the CSBI Common Stock issued to the undersigned
pursuant to the Merger has not been transferred in such manner to justify the
removal of the legend therefrom.  Upon the request of the undersigned, CSBI
shall cause the certificates representing the shares of CSBI Common Stock issued
to the undersigned in connection with the Merger to be reissued free of any
legend relating to restrictions on transfer by virtue of ASR 130 and 135 as soon
as practicable after the requirements of ASR 130 and 135 have been met.  In
addition, if the provisions of Rules 144 and 145 are amended to eliminate
restrictions applicable to the CSBI Common Stock received by the undersigned
pursuant to the Merger, or at the expiration of the restrictive period set forth
in rule 145(d), CSBI, upon the request of the undersigned, will cause the
certificates representing the shares of CSBI Common Stock issued to the
undersigned in connection with the Merger to the reissued free of any legend
relating to the restrictions set forth in Rules 144 and 145(d) upon receipt by
CSBI of an opinion of its counsel to the effect that such legend may be removed.

    5.  Understanding of Restrictions on Dispositions.  The undersigned has
carefully read the Agreement and this Affiliate Agreement and discussed their
requirements and impact upon his ability to sell, transfer, or otherwise dispose
of the shares of CSBI Common Stock received by the undersigned, to the extent he
believes necessary, with his counsel or counsel for BCG.

    6.  Filing of Reports by CSBI. CSBI agrees, for a period of three years
after the effective date of the Merger, to file on a timely basis all reports
required to be filed by it pursuant to Section 13 of the Securities Exchange Act
of 1934, as amended, so that the public information provisions of Rule 145(d)
promulgated by the SEC as the same are presently in effect will be available to
the undersigned in the event the undersigned desires to transfer any shares of
CSBI Common Stock  issued to the undersigned pursuant to the Merger.

    7.  Transfer Under Rule 145(d).  If the undersigned desires to sell or
otherwise transfer the shares of CSBI Common Stock received by him in connection
with the Merger at any time during the restrictive period set forth in Rule
145(d), the undersigned will provide the necessary representation letter to the
transfer agent for CSBI Common Stock together with such additional information
as the transfer agent may reasonably request.  If CSBI's counsel concludes that
such proposed sale or transfer complies with the requirements of Rule 145(d),
CSBI shall cause such counsel to provide such opinions as may be necessary to
CSBI's Transfer Agent so that the undersigned may complete the proposed sale or
transfer.

    8.  Acknowledgments.  The undersigned recognizes and agrees that the
foregoing provisions also apply with respect to BCG Common Stock held by, and
CSBI Common Stock issued in connection with the Merger to, (i) the undersigned's
spouse, (ii) any relative of the undersigned or of the undersigned's spouse who
has the same home as the undersigned, (iii) any trust or estate in which the
undersigned, the undersigned's spouse, and any such relative collectively own at
least 10% beneficial interest or of which any of the foregoing serves as
trustee, executor, or in any similar capacity, and (iv) any corporation or other
organization in which the undersigned, the undersigned's spouse and any such
relative collectively own at least 10% of any class of equity securities or of
the equity interest.  The undersigned further recognizes that, in the event that
the undersigned is a director or executive officer of CSBI or becomes a director
or executive officer of CSBI upon consummation of the Merger, among other
things, any sale of CSBI Common Stock by the undersigned within a period of less
than six months following the  effective time of the Merger may subject the
undersigned to  liability pursuant to Section 16(b) of the Securities Exchange
Act of 1934, as amended.

                               MATTERS TO WHICH
                      KILPATRICK STOCKTON LLP WILL OPINE

    1.  BCG is a bank holding company duly organized, validly existing, and in
good standing under the laws of the State of Georgia with corporate power and
authority to conduct its business and to own and use its Assets.

    2.  The deposits of the BCG Banks are insured by the Federal Deposit
Insurance Corporation to the extent provided by law.

    3.  BCG's authorized shares consists of 3,000,000 shares of BCG Common
Stock, of which 2,268,097 shares were outstanding as of March 31, 1997 and
__________ shares were outstanding as of the Closing Date. As of March 31, 1997,
212,915 shares of BCG Common Stock were reserved for issuance upon the exercise
of outstanding stock options and purchases under the BCG Option Plan.  As of the
Closing Date _________ shares of BCG Common Stock were reserved for issuance 
upon the exercise of outstanding stock options and purchases under the BCG
Option Plan. The shares of BCG Common Stock have been duly authorized and
validly issued, were not issued in violation of any statutory preemptive rights
of shareholders, and are fully paid and nonassessable. To our Knowledge, there
are no options, subscriptions, warrants, calls, rights or commitments obligating
BCG to issue or acquire any of its equity securities except those issued
pursuant to the BCG Option Plan.

    4.  The execution and delivery by BCG of the Agreement do not, and if BCG
was now to perform its obligations under the Agreement such performance would
not, violate or contravene any provision of the Articles of Incorporation or
Bylaws of BCG or, to our Knowledge, result in any breach of, or default or
acceleration under any mortgage, agreement, lease, indenture, or other
instrument, order, judgment or decree to which BCG is a party or by which it is
bound other than pursuant to that certain Loan Agreement with First Liberty Bank
dated as of _________, 199_, a copy of which has been provided to CSBI.

    5.  The Agreement has been duly and validly executed and delivered by BCG,
and assuming valid authorization, execution and delivery by CSBI, constitutes a
valid and binding agreement of BCG enforceable in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, or similar laws affecting creditors' rights generally, provided,
however, that we express no opinion as to the availability of the equitable
remedy of specific performance.

acceleration under any mortgage, agreement, lease, indenture, or other
instrument, order, judgment, or decree to which CSBI is a party or by which CSBI
is bound.

    3.  The Agreement has been duly and validly executed and delivered by CSBI,
and assuming valid authorization, execution and delivery by BCG, constitutes a

Item 20.  Indemnification of Directors and Officers

     The provisions of the Georgia Business Corporation Code and the
Registrant's Bylaws set forth the extent to which the Registrant's directors and
officers may be indemnified against liabilities they may incur while serving in
such capacities.  Under these indemnification provisions, the Registrant is

expenses (including attorneys' fees) incurred by such director or officer in

administrative, or investigative, and whether formal or informal, to which such
director or officer was made a party, or in defense of any claim, issue or
matter therein, by reason of the fact that such director or officer is or was a
director or officer of the Registrant or who, while a director of the
Registrant, is or was serving at the Registrant's request as a director,
officer, partner, trustee, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan, or other enterprise,
to the extent that such director or officer has been successful, on the merits
or otherwise, in such defense.  The  Registrant also must indemnify any of its
directors, and may indemnify any of its officers, against any liability incurred
in connection with any threatened, pending, or completed action, suit, or
proceeding, whether civil, criminal, administrative, or investigative, and
whether formal or informal, by reason of the fact that such director or officer
is or was a director or officer of the Registrant or who, while a director or
officer of the Registrant, is or was serving at the Registrant's request as a
director, officer, partner, trustee, employee, or agent of another corporation,
partnership, joint venture, trust, employee benefit plan, or other enterprise,
if such director or officer acted in a manner such director or officer believed
in good faith to be in, or not opposed to, the best interests of the Registrant,
or, with respect to any criminal proceeding, had no reasonable cause to believe
such director's or officer's conduct was unlawful, if a determination has been
made that the director or officer has met these standards of conduct. Such
indemnification in connection with a proceeding by or in the right of the
Registrant, however, is limited to reasonable expenses, including attorneys'
fees, incurred in connection with the proceeding.  The Registrant may also
provide advancement of expenses incurred by a director or officer in defending
any such action, suit, or proceeding upon receipt of a written affirmation of
such officer or director that such director or officer has met certain standards
of conduct and an undertaking by or on behalf of such director or officer to
repay such advances unless it is ultimately determined that such director or
officer  is entitled to indemnification by the Registrant.

     The Registrant may not indemnify a director or officer in connection with a
proceeding by or in the right of the Registrant in which the director or officer
was adjudged liable to the Registrant, or in connection with a proceeding in
which he was adjudged liable on the basis that he improperly received a personal
benefit.

     The Registrant's Articles of Incorporation contain a provision which
provides that, to the fullest extent permitted by the Business Corporation Code
of Georgia, directors of the Registrant shall not be personally liable to the
Registrant or its shareholders for monetary damages for breach of his duty of
care or any other duty as a director.

     The Registrant maintains an insurance policy insuring the Registrant and
directors and officers of the Registrant against certain liabilities, including
liabilities under the Securities Act of 1933.

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:

           (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;

          (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; Provided,
                                                                   --------
however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
- -------
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed by the registrant pursuant to section 13 or section 15(d)
of the Securities Exchange Act of 1934 that are incorporated by reference 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.

                                      II-2
<PAGE>
 
    (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
the initial bona fide offering thereof.

    (c) 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 Registrant's Articles of Incorporation or Bylaws,
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the 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 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.

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

    (e) 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:  Proposed Merger Involving Bank Corporation of Georgia and Century
          South Banks, Inc.

Ladies and Gentlemen:

     We have acted as counsel to Century South Banks, Inc. ("CSBI"), in
connection with the proposed merger of Bank Corporation of Georgia ("BCG") with
and into Century South Banks, Inc. (the "Merger") First South Bank, National
Association and Ameribank, National Association (collectively, "BCG Banks") will
become wholly-owned subsidiaries of CSBI. The Merger will be effected pursuant
to the Agreement and Plan of Merger by and between CSBI and BCG dated as of
March 31, 1997 and amended July 11, 1997 (the "Agreement").

     In our capacity as counsel to CSBI, our opinion has been requested with
respect to certain of the federal income tax consequences of the proposed
Merger. All capitalized terms used herein without definition shall have the
respective meanings specified in the Agreement and, unless otherwise specified,
all section references herein are to the Internal Revenue Code of 1986, as
amended (the "Code").

     In rendering the opinions expressed herein, we have examined such documents
as we have deemed appropriate, including:

     (1)  the Agreement;

     (2) the Registration Statement and Proxy Statement/Prospectus being filed
with the Securities and Exchange Commission regarding the Merger; and

     (3) such additional documents as we have considered relevant.

     In our examination of such documents, we have assumed, with your consent,
that all documents submitted to us as photocopies faithfully reproduce the
originals thereof, that such originals are authentic, that all such documents
have been or will be duly executed to the extent required, and that all
statements set forth in such documents are accurate. With your permission, we
have also assumed certain other factual matters set forth more fully below.

     We have served as counsel to Century South Banks, Inc. ("CSBI"), a
corporation organized and existing under the laws of the State of Georgia, in
connection with the execution and delivery of the Agreement and Plan of Merger,
dated March 31, 1997, and amended on July 11, 1997 (the "Agreement"), by and
between CSBI and Bank Corporation of Georgia ("BCG").  This opinion is delivered
pursuant to Section 9.3(d) of the Agreement.

     This opinion letter is limited by, and shall be interpreted in accordance
with, the January 1, 1992 edition of Interpretive Standards Applicable to
                                     ------------------------------------
Certain Legal Opinions to Third Parties in Corporate Transactions, adopted by
- -----------------------------------------------------------------
the Legal Opinion Committee of the Corporate and Banking Law Section of the
State Bar of Georgia, which Interpretive Standards are incorporated in this
opinion letter by this reference.  As a consequence, this opinion letter is
subject to a number of qualifications, exceptions, definitions, limitations on
coverage, and other limitations, all as more particularly described in the
Interpretive Standards, and this opinion should be read in conjunction
therewith.  Capitalized terms used in this opinion letter and not otherwise
defined herein shall have meanings assigned to such terms in the Interpretive
Standards and the Agreement.

     In rendering this opinion, we have examined the corporate books and records
of CSBI and the Registration Statement on Form S-4 filed by CSBI with the
Securities and Exchange Commission on August __, 1997, and made such other
investigations as we have deemed necessary.  In such examinations we have
assumed the genuineness of all signatures on all original documents, the
conformity to the original documents of all copies submitted to us, and (except
where our opinion expressly addresses execution and delivery) the due execution
and delivery of all documents where due execution and delivery are prerequisite
to the effectiveness thereof.

     As to questions of fact material to this opinion, we have relied solely
upon the representations and warranties as to factual matters contained in
certificates and statements of officers of CSBI and certain public officials and
upon the accuracy and completeness of the representations and warranties of the
parties to the Agreement.  We have made no independent investigations with
regard thereto and, accordingly, we do not express any view or belief as to
matters that might have been disclosed by independent verification.

     Based upon and subject to the foregoing, we are of the opinion that:

     1.  CSBI has the corporate power and authority to conduct its business as
described in the Proxy Statement included in the Registration Statement  and to
own and use its Assets.
<PAGE>
 
     2.  The execution and delivery of the Agreement and compliance with its
terms do not and will not violate or contravene any provision of the Articles of
Incorporation or Bylaws of CSBI, or, to our knowledge, any order, arbitration
award, judgment, or decree to which CSBI is a party or by which CSBI is bound.

     3.  The Agreement has been duly and validly executed and delivered by CSBI
and assuming valid authorization, execution and delivery by BCG, constitutes a
valid and binding agreement of CSBI enforceable in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, or similar laws affecting creditors' rights generally, provided,
however, that we express no opinion as to the availability of the equitable
remedy of specific performance.

     4.  The shares of the $1.00 par value common stock of CSBI to be issued to
the shareholders of BCG upon consummation of the Merger have been registered
under the Securities Act of 1933, as amended, and when issued in accordance with
the Agreement, will be validly issued, fully paid and nonassessable.

     We hereby confirm to you that CSBI is a corporation validly existing under
the laws of the State of Georgia.  The foregoing statement is based solely upon
a certificate provided by the Georgia Secretary of State dated _______________ 
_____________, 1997 and is limited to the meaning ascribed to such certificate 
by the Georgia Secretary of State.

     We are admitted to practice law in the State of Georgia only and do not
hold ourselves out as being experts on the law of any other jurisdiction.

     This opinion is limited to the matters expressly opined on herein, and no
opinion may be implied or inferred beyond those expressly stated.  This opinion
is rendered as of the date hereof and we make no undertaking and expressly
disclaim any duty to supplement or update such opinion, if, after the date
hereof, facts or circumstances come to our attention or changes in the law occur
which could affect such opinion.  This opinion is being furnished to you solely
for your benefit, and is not to be used, circulated, quoted or otherwise
referred to for any other purpose without our prior express written consent and
may not be relied upon by any other person without our express written consent.


                                 Sincerely,


                                 /s/ Thomas O. Powell
