addition, such material can be inspected and copied at the public reference
facilities referred to above and at Regional Offices of the SEC as follows:

York 10048 and the Chicago Regional Office, Citicorp Center, 500 West Madison
Street, Suite 1400, Chicago, Illinois 60661. The SEC also maintains a Web site
that contains reports, proxy statements and other information regarding
registrants that file electronically with the SEC. The address of such site is
http://www.sec.gov. NCBC Common Stock is traded over-the-counter on the Nasdaq
National Market tier and is quoted under the trade symbol "NCBC," and such
reports, proxy statements and other information concerning NCBC can be
inspected and copied at the offices of Nasdaq Operations, 1735 K Street, N.W.,

contain all the information set forth in the Registration Statement on Form S-
4 and exhibits thereto (the "Registration Statement") that NCBC has filed with
the SEC under the Securities Act of 1933 (the "Securities Act"), to which
reference is hereby made.
 
                          FORWARD-LOOKING STATEMENTS
 
  This Proxy Statement/Prospectus may contain or incorporate by reference
certain forward-looking statements within the meaning of Section 27A of the
Securities Act and Section 21E of the Exchange Act with respect to the
financial condition, results of operations and business of NCBC and FCB.
Statements in this document that are not historical facts are hereby
identified as "forward-looking statements" for the purpose of the safe harbor
provided by Section 12E of the Exchange Act and Section 27A of the Securities
Act. NCBC and FCB caution readers that such "forward-looking statements,"
including without limitation, those relating to NCBC's and FCB's future
business prospects, revenues, working capital, liquidity, capital needs,
interest costs and income, wherever they occur in this document or in other
statements attributable to NCBC or FCB, are necessarily estimates reflecting
the best judgment of NCBC and FCB senior management and involve a number of
risks and uncertainties that could cause actual results to differ materially
from those suggested by the "forward-looking statements." Such "forward-
looking statements" should, therefore, be considered in light of various
important factors, including those set forth in this Proxy
Statement/Prospectus. Important factors currently known to management that
could cause actual results to differ materially from those in forward-looking
statements include significant fluctuations in interest rates, inflation,
economic recession, significant changes in the federal and state legal and
regulatory environment, significant underperformance in NCBC's and FCB's
portfolio of outstanding loans, and competition in NCBC's and FCB's markets.
Other factors set forth from time to time in NCBC's reports and registration
statements filed with the SEC should also be considered. NCBC undertakes no
obligation to update or revise forward-looking statements to reflect changed
assumptions, the occurrence of unanticipated events or changes to future
operating results over time.

company and owns National Bank of Commerce; Nashville Bank of Commerce; NBC
Bank, F.S.B. (Knoxville); NBC Bank, F.S.B. (Roanoke) and 49 percent of First
Market Bank, F.S.B. (Richmond). At present, NCBC provides its financial
institutions with financial advice and counsel and performs the record-keeping
functions necessary to comply with accounting and regulatory requirements. In
addition, NCBC owns National Commerce Bank Services, Inc., which provides in-
store bank consulting services; Commerce General Corporation and NBC Capital
Markets Group, Inc., which provide data processing and broker-dealer services,
respectively; NBC Insurance Services, Inc., a consumer insurance subsidiary;

  NCBC, a Tennessee corporation, was formed in February 1966 as a Tennessee
financial corporation. The corporate name was changed in 1970, and the present
name was adopted in May 1978. NCBC common stock, par value $2.00 per share (the
"Common Stock"), is traded on The Nasdaq Stock Market's National Market System
under the symbol "NCBC." Unless the context otherwise requires, references to
NCBC include National Commerce Bancorporation and its subsidiaries. NCBC's
principal executive offices are located at One Commerce Square, Memphis,
Tennessee 38150, and its telephone number is (901) 523-3242.
 
  FCB. First Community Bancorp, Inc. ("FCB"), a Georgia corporation, was
organized on May 31, 1989, for the purpose of acquiring all of the issued and
outstanding common stock of First Community Bank & Trust (the "Bank"). Pursuant
to a Plan of Reorganization, effective December 1, 1989, FCB acquired all of
the issued and outstanding shares of common stock of the Bank. As a result of
this transaction, the former shareholders of the Bank became the shareholders
of FCB, and the Bank became a wholly owned subsidiary of FCB. FCB's principal
executive offices are located at 827 Joe Frank Harris Parkway, S.E.,
Cartersville, Georgia 30120, and its telephone number is (706) 382-1495.
 
  The Bank is a financial institution which was organized under the laws of the
State of Georgia on July 11, 1988 and, on October 23, 1989, began operation of
a full-service commercial banking business based in Bartow County, Georgia. The
Bank provides such customary banking services as checking and savings accounts,
various types of time deposits, safe deposit facilities and individual
retirement accounts. It also makes secured and unsecured loans and provides
other financial services to its customers. While the Bank has trust powers,
such powers are currently exercised only to permit the Bank to serve as
custodian of its individual retirement accounts. The Bank engages in a general
commercial banking business in its community, emphasizing the banking needs of
individuals and small- to medium-sized businesses and professional concerns.
 
THE MEETING
 
  The Special Meeting of FCB Shareholders (the "Meeting") will be held at the
main office of the Bank at 827 Joe Frank Harris Parkway, S.E., Cartersville,
Georgia 30120, on      , 1998 at    p.m., local
 
                                       1

time. The purpose of the Meeting is to consider and vote upon the approval and
adoption of the Merger Agreement. Only holders of shares of FCB Common Stock of
record at the close of business on      , 1998 (the "Record Date"), will be
entitled to vote at the Meeting. As of the Record Date, there were 430,204
shares of FCB Common Stock outstanding and entitled to vote, with each share
entitled to one vote. As of the Record Date, approximately [33.45]% of the
outstanding shares of FCB Common Stock were beneficially owned by officers and
directors of FCB and their affiliates. The presence in person or by proxy of
the holders of a majority of the shares of FCB Common Stock outstanding as of
the Record Date is necessary to constitute a quorum at the Meeting. The
affirmative vote of the holders of a majority of the shares of FCB Common Stock
entitled to vote is necessary to approve and adopt the Merger Agreement. See
"Information Concerning the Meeting--Vote Required."
 
  A form of proxy for the FCB Common Stock is enclosed with this Proxy
Statement/Prospectus. Holders of FCB Common Stock are requested to sign and
return the proxy. All shares of FCB Common Stock represented by properly
executed proxies, unless such proxies have been previously revoked, will be
voted in accordance with the instructions indicated on such proxies. If no
instructions are indicated, such shares will be voted for approval of the
Merger Agreement and, in the discretion of the proxy holder, as to any other
matter which may properly come before the Meeting. See "The Information
Concerning the Meeting--Revocability of Proxies" and "--Solicitation of
Proxies."
 
THE MERGER
 
  General. The Merger Agreement, a copy of which is attached as Appendix I and
incorporated by reference in this Proxy Statement/Prospectus, provides for the
Merger of FCB with and into NCBC in accordance with the applicable provisions
of the Georgia Business Corporation Code (the "GBCC") and the Tennessee Code
Annotated (the "Tennessee Code"). NCBC will be the surviving corporation of the
Merger. The separate existence of FCB will cease following the Merger and the
Bank will become a wholly owned bank subsidiary of NCBC. Subject to the terms,
conditions and procedures set forth in the Merger Agreement, upon consummation
of the Merger at the time and date specified in the articles of merger to be
filed to effect the Merger (the "Effective Time"), each of the issued and
outstanding shares of FCB Common Stock (excluding treasury shares and shares
held by FCB Shareholders who perfect their dissenters' rights) will be
converted, without any further action on the part of FCB Shareholders, into the
right to receive 3.2684 shares of NCBC Common Stock (the "Exchange Ratio"). FCB
believes it will satisfy this requirement. FCB Shareholders who properly
exercise and perfect their dissenters' rights under the GBCC will be paid the
statutory fair value of their shares in cash. In addition, cash will be paid to
FCB Shareholders in lieu of fractional shares otherwise issuable in the Merger
based on a price of $21.519 per share of NCBC Common Stock.
 
  Background of the Merger. The managements of NCBC and FCB began considering a
potential combination in March 1998. A letter of intent was finalized and
executed on April 9, 1998. The Merger Agreement was approved by the FCB Board
of Directors on August 3, and by the NCBC Board of Directors on April 22. The
Merger Agreement was executed on August 5, 1998. See "The Merger--Background of
the Merger."
 
  Board of Directors' Recommendation. The Board of Directors of FCB voted to
approve the Merger Agreement as being in the best interests of FCB and FCB
Shareholders and recommends that FCB Shareholders vote for the approval of the
Merger and the approval and adoption of the Merger Agreement. See "The Merger--
Reasons for the Merger; Board of Directors' Recommendation."
 
  Covenants; Conditions; Representations and Warranties; Amendment and
Termination. The respective obligations of the parties to consummate the Merger
are subject to, among other things, the requisite vote of FCB Shareholders
approving the Merger and compliance with certain regulatory requirements.
Additional conditions to the obligations of NCBC and FCB to consummate the
Merger are discussed in "The Merger--Covenants; Conditions; Representations and
Warranties; Amendment and Termination."
 
                                       2
<PAGE>
 
 
  The Merger Agreement may be amended by agreement between FCB and NCBC, but no
amendment reducing the consideration to be received by FCB Shareholders is
valid unless approved by the FCB Shareholders. The Merger Agreement may be
terminated by either NCBC or Merger Subsidiary, on the one hand, or FCB, on the
other hand, if by November 30, 1998, specified conditions in the Merger
Agreement have not been satisfied or waived.
 
  In addition to the conditions described in the preceding sentence, the
obligation of NCBC to consummate the Merger is subject the following
conditions: (i) exclusive of gains or losses on transactions in securities,
total consolidated shareholders equity of FCB at the time of the closing shall
not be less than $8,330,000; (ii) FCB shall own, free and clear of any liens,
not less than 100% of the outstanding capital stock of the Bank; (iii) from and
after December 31, 1997, neither FCB nor the Bank shall have consummated any
extraordinary sale of assets nor any material investment portfolio
restructuring; and (v) certain FCB officers shall have entered into non-compete
agreements with NCBC and the Bank.
 
  Regulatory or Other Legal Considerations. The Merger is subject to approval
by the Board of Governors of the Federal Reserve System (the "FRB") under the
Bank Holding Company Act of 1956, as amended (the "BHC Act"), and the
expiration of the 30-day Department of Justice waiting period. NCBC filed an
application for such approval on or about     , 1998. The approval was granted
on      , 1998. The Merger is also subject to approval by the State of Georgia
Department of Banking and Finance. NCBC filed an application for such approval
on or about    , 1998. The approval was granted on    , 1998. See "The Merger--
Regulatory and Other Legal Considerations."
 
  Federal Income Tax Considerations. NCBC and FCB will receive an opinion of
NCBC's counsel that the Merger will constitute a "reorganization," within the
meaning of Section 368(a) of the Internal Revenue Code of 1986 (the "Code"),
and that no gain or loss will be recognized by the FCB Shareholders for federal
income tax purposes upon the conversion of FCB Common Stock into NCBC Common
Stock pursuant to the Merger (except with respect to cash received in lieu of
fractional shares of NCBC Common Stock) or by holders of FCB Options (as
defined, see "The Merger--General") upon the conversion of such options into
rights with respect to NCBC Common Stock. See "The Merger--Federal Income Tax
Considerations."
 
  Comparison of Rights of FCB and NCBC Shareholders. FCB is incorporated under
the laws of the State of Georgia. NCBC is incorporated under the laws of the
State of Tennessee. FCB Shareholders, whose rights as shareholders are
currently governed by Georgia law and the FCB Articles of Incorporation and
Bylaws, upon consummation of the Merger will become shareholders of NCBC and
their rights as NCBC shareholders will be governed by Tennessee law and the
NCBC Restated Charter (the "NCBC Charter") and Bylaws. The NCBC Charter and
Bylaws contain certain provisions intended to deter certain takeover attempts.
The FCB Articles of Incorporation and Bylaws contain similar, but not
identical, provisions. See "Comparison of Rights of FCB and NCBC Shareholders."
 
  Dissenters' Rights. FCB Shareholders who do not vote in favor of the Merger
and who comply with the applicable provisions of the GBCC, which provisions
require, among other things, the filing of a written notice of the
shareholder's intention to demand payment for his shares before the vote with
respect to the Merger Agreement is taken prior to or at the Meeting, will be
entitled, if the Merger is consummated, to have a Georgia court determine the
statutory fair value of his shares of FCB Common Stock and to receive payment
of that amount in cash in lieu of receiving shares of NCBC Common Stock in the
Merger. See "The Merger--Dissenters' Rights" and Appendix III.

(1) Pro forma data reflecting the Merger and certain other acquisitions are not
    presented because such acquisitions individually and combined do not have a
    significant effect on the data as presented. On January 29, 1998, NCBC
    acquired First Citizens Bancshares Company, a one bank holding company
    located in Marion, Arkansas. In connection therewith, NCBC issued 557,582
    shares of NCBC Common Stock (after giving effect to a two-for-one stock
    split effective July 1, 1998). On March 31, 1998, NCBC acquired Bancshares
    of West Memphis, a one bank holding company located in West Memphis,
    Arkansas. In connection therewith, NCBC issued 1,699,920 shares of NCBC
    Common Stock (after giving effect to a two-for-one stock split effective
    July 1, 1998). On August 1, 1998, NCBC acquired CBC Bancshares, Inc., a one
    bank holding company located in Collierville, Tennessee. In connection
    therewith, NCBC issued 534,531 shares of NCBC Common Stock. Acquisitions
    accounted for under the pooling of interests accounting method are included
    for all periods presented, while acquisitions accounted for under the
    purchase accounting method are included from the date of acquisition.
(2) Represents NCBC data equivalent to one share of FCB Common Stock computed
    by multiplying NCBC historical data by the Exchange Ratio.
(3) Net income per common share (basic) is based on the average number of
    common shares outstanding during the periods presented. Diluted net income
    per common share incudes an adjustment for the assumed conversion of all
    potentially dilutive securities.
(4) NCBC declared quarterly dividends per common share of $.06 beginning the
    fourth quarter of 1996. In the fourth quarter of 1997, the dividend was
    increased to $.07 per common share. On July 9, 1998 the NCBC Board of
    Directors declared a quarterly dividend of $.08 per common share.
(5) FCB's management has for the past two years declared dividends. In 1997, a
    2% stock dividend was declared, which resulted in the issuance of 8,258
    shares. In 1996, a cash dividend of $139,531 in the aggregate ($.30 per
    share of FCB Common Stock) was declared. The Merger Agreement restricts the
    right of FCB to declare dividends. Thereunder, FCB is prohibited from
    declaring or paying dividends or making any other distribution in respect
    of FCB Common Stock, with the exception of a cash dividend, which the
    parties have agreed will be $.49 per share of FCB Common Stock outstanding,
    the declaration date of which shall be before 30 days prior to the
    consummation of the Merger. The right of FCB to declare and pay such
    dividend is subject to certain restrictions. See "The Merger--Covenants;
    Conditions; Representations and Warranties; Amendment and Termination."

                                 RISK FACTORS
 
TRANSFER OF CONTROL TO NCBC
 
  FCB Shareholders currently control FCB through their ability to elect the
Board of Directors of FCB and to vote on various matters affecting FCB. The
Merger will transfer control of FCB from the FCB Shareholders to NCBC. As of
the Effective Time, the FCB Shareholders will become shareholders of NCBC, a
multi-bank holding company. As a result of the Merger, the former FCB
Shareholders will no longer have the ability to control or influence the
management policies of FCB's operations, and as shareholders of NCBC their
ability to influence the management policies of NCBC will be limited due to
the fact that they will hold a relatively small percentage of the voting stock
of NCBC.
 
COMPETITION
 
  NCBC's banking subsidiaries compete with other banking institutions on the
basis of service, convenience and, to some extent, price. Due in part to both
regulatory changes and consumer demands, banks have experienced increased
competition from other financial entities offering similar products.
Competition from both bank and non-bank organizations is expected to continue.
 
RISK FROM GENERAL ECONOMIC CONDITIONS
 
  In addition, general economic conditions impact the banking industry. The
credit quality of NCBC's loan portfolio necessarily reflects, among other
matters, the general economic conditions in the areas in which it conducts its
business. The continued financial success of NCBC and its subsidiaries depends
somewhat on factors which are beyond NCBC's control, including national and
local economic conditions, the supply and demand for investable funds,
interest rates and federal, state and local laws affecting these matters. Any
substantial deterioration in any of the foregoing conditions could have a
material adverse effect on NCBC's financial condition and results of
operations, which, in all likelihood, would adversely affect the market price
of NCBC Common Stock. See "Summary--Market Prices of NCBC and FCB Common
Stock."
 
LESS ATTRACTIVE ACQUISITION TARGET
 
  The NCBC Charter and Bylaws contain several provisions which may make NCBC a
less attractive target for acquisition by any entity that who does not have
the support of NCBC's Board of Directors. Such provisions include, among other
things, the requirement of a supermajority vote of shareholders or directors
to approve certain business combinations and other corporate actions, a
minimum price provision, several special procedural rules, a staggered Board
of Directors, and the limitation that shareholder actions without a meeting
may only be taken by unanimous written shareholder consent. FCB's Articles of
Incorporation and Bylaws contain similar restrictions, although under Georgia
law FCB's shareholders may take action without a meeting only by unanimous
written consent unless otherwise provided in the bylaws. See "Comparison of
Rights of FCB and NCBC Shareholders--Charter and Bylaw Provisions Affecting
NCBC Common Stock."

                      INFORMATION CONCERNING THE MEETING
 
THE MEETING
 
  The Meeting will be held at the main office of the Bank at 827 Joe Frank
Harris Parkway, S.E., Cartersville, Georgia 30120, on      , 1998 at    p.m.,
local time. The purpose of the Meeting is to consider and vote upon the
approval and adoption of the Merger Agreement. Only holders of FCB Common
Stock of record at the close of business on the Record Date will be entitled
to receive notice of and to vote at the Meeting. As of the Record Date, there
were [430,204] shares of FCB Common Stock outstanding and entitled to vote,
with each such share entitled to one vote.
 
VOTE REQUIRED
 
  Under the GBCC, the affirmative vote of the holders of a majority of the
outstanding shares of FCB Common Stock entitled to vote is required to approve
and adopt the Merger Agreement. On the Record Date, there were approximately
816 holders of record of FCB Common Stock. On such date, the directors and
officers of FCB and their affiliates beneficially owned, and expressed their
intent to vote in favor of the Merger, a total of approximately [33.45%] of
the outstanding shares of FCB Common Stock. At the date of this Proxy
Statement/Prospectus, neither NCBC nor any of its affiliates owned any of the
outstanding shares of FCB Common Stock.
 
VOTING OF PROXIES
 
  Shares of FCB Common Stock represented by properly executed proxies received
at or prior to the Meeting will be voted at the Meeting in the manner
specified by the holders of such shares. Properly executed proxies which do
not contain voting instructions will be voted FOR approval and adoption of the
Merger Agreement. Any stockholder present in person or by proxy (including
broker non-votes) at the Meeting who abstains from voting will be counted for
purposes of determining whether a quorum exists. With respect to all matters
considered at the Meeting, an abstention (or broker non-vote) has the same
effect as a vote AGAINST the proposal.
 
  If any other matters are properly presented at the Meeting, the person or
persons named in the form of proxy enclosed with this Proxy
Statement/Prospectus and acting thereunder will have discretion to vote on
such matters in accordance with their best judgment, unless the proxy
indicates otherwise. FCB has no knowledge of any matters to be presented at
the Meeting, other than the matters described in this Proxy
Statement/Prospectus.
 
REVOCABILITY OF PROXIES
 
  The grant of a proxy on the enclosed form of proxy does not preclude an FCB
Shareholder from voting in person or otherwise revoking a proxy. Attendance at
the meeting will not in and of itself constitute revocation of a proxy. An FCB
Shareholder may revoke a proxy at any time prior to its exercise by delivering
to Danny F. Dukes, Secretary of FCB, a duly executed revocation or proxy
bearing a later date or by voting in person at the Meeting.
 
SOLICITATION OF PROXIES
 
  FCB will bear the cost of the solicitation of proxies in connection with the
Meeting, except that NCBC will bear a portion of the filing fees payable in
connection with the Registration Statement of which this Proxy
Statement/Prospectus is a part and this Proxy Statement/Prospectus and
printing costs incurred in connection with the printing of such Registration
Statement and this Proxy Statement/Prospectus based on the relative asset
sizes of the parties at December 31, 1997. In addition to solicitation by
mail, the directors, officers and employees of FCB may solicit proxies by
telephone or telegram or in person. Such persons will not be additionally
compensated, but will be reimbursed for reasonable out-of-pocket expenses
incurred in connection with such solicitation. Arrangements may also be made
with brokerage firms, nominees, fiduciaries and other custodians, for the
forwarding of solicitation materials to the beneficial owners of shares held
of record by such persons, and FCB will reimburse such persons for their
reasonable out-of-pocket expenses in connection therewith.
 
OTHER MATTERS TO BE CONSIDERED
 
  It is not anticipated that any matter other than matters described above
will be brought before the Meeting.

                                  THE MERGER
 
  The descriptions of the terms and conditions of the Merger, the Merger
Agreement, and any related documents in this Proxy Statement/Prospectus are
qualified in their entirety by reference to the copy of the Merger Agreement
attached as Appendix I to this Proxy Statement/Prospectus, to the Georgia
statute governing dissenters' rights, a copy of which is attached as Appendix
III to this Proxy Statement/Prospectus, to the Registration Statement of which
this Proxy Statement/Prospectus is a part and to the exhibits to the
Registration Statement.
 
GENERAL
 
  Subject to the terms of the Merger Agreement, FCB will be merged with and
into NCBC in accordance with Georgia law. NCBC will be the surviving
corporation of the Merger and the separate existence of FCB will cease
following the Merger. The Bank will become a wholly owned subsidiary of NCBC
as a result of the Merger. If all conditions to consummation of the Merger are
satisfied or waived, unless the Merger Agreement is terminated in accordance
with its terms, Articles of Merger reflecting the Merger will be filed with
the Secretary of State of the State of Georgia, and the Merger will then
become effective at the Effective Time. It is presently contemplated that the
Effective Time will occur as soon as practicable after the Meeting and the
receipt of the approval of the FRB and the Georgia Department of Banking and
Finance and the expiration of the statutory Department of Justice 30-day
waiting period following FRB approval, subject to the conditions described
under "The Merger--Covenants; Conditions; Representations and Warranties;
Amendment and Termination."
 
  At the Effective Time, each of the issued and outstanding shares of FCB
Common Stock (other than treasury shares and shares held by FCB Shareholders
who perfect their dissenters' rights) will be converted, without any action on
the part of the holders of those shares, into the right to receive 3.2684
shares of NCBC Common Stock. FCB Shareholders who properly exercise and
perfect their dissenters' rights under the GBCC will be paid the statutory
fair value of their shares in cash. In the event NCBC changes the number of
shares of NCBC Common Stock issued and outstanding prior to the Effective Time
as a result of a stock split, stock dividend or similar recapitalization, and
the record date therefor is prior to the Effective Time, the ratio under which
shares of FCB Common Stock will be converted into shares of NCBC Common Stock
will be proportionally adjusted. Furthermore, at the Effective Time, all
rights with respect to FCB Common Stock pursuant to stock options ("FCB
Options") granted by FCB under its qualified stock options plans, its
employment agreement with J. Steven Walraven, the President of the Bank, and
incentive stock option plan (collectively, the "FCB Option Plans"), which are
outstanding at the Effective Time, whether or not exercisable, shall be
converted into and become rights with respect to NCBC Common Stock.
 
  On the date of this Proxy Statement/Prospectus, the closing sale price of a
share of NCBC Common Stock on the Nasdaq National Market tier was $[22.000].
Based on such price, the equivalent value of a share of FCB Common Stock would
be $[71.900] based on the Exchange Ratio. The market price of NCBC Common
Stock is subject to fluctuations and could be more or less than its market
price on the date of this Proxy Statement/Prospectus. Any such change will
cause a corresponding change in the equivalent value of a share of FCB Common
Stock. FCB SHAREHOLDERS ARE URGED TO OBTAIN UPDATED MARKET INFORMATION
CONCERNING NCBC COMMON STOCK.
 
  No fractional shares of NCBC Common Stock will be issued as a result of the
Merger. In lieu of the issuance of fractional shares, each FCB Shareholder who
otherwise would be entitled to a fractional share of NCBC Common Stock will
receive a cash payment (without interest) equal to the product of the Current
Market Price Per Share ($21.52) multiplied by the fractional share of NCBC
Common Stock otherwise issuable.
 
BACKGROUND OF THE MERGER
 
  The managements of NCBC and FCB began considering a potential combination in
March 1998. A letter of intent was finalized and executed as of April 9, 1998.
The Merger Agreement was approved by the FCB Board of Directors on August 3,
1998, and by the NCBC Board of Directors on April 22, 1998. The Merger
Agreement was executed on August 5, 1998.

REASONS FOR THE MERGER; BOARD OF DIRECTORS' RECOMMENDATION
 
  Reasons for the Merger. The Board of Directors of FCB believes that the
Merger is in the best interests of FCB and the FCB Shareholders. The market
value of the NCBC Common Stock to be issued in the Merger represents a
substantial premium over the book value of FCB Common Stock. The dividends
currently paid on the 3.2684 shares of NCBC Common Stock into which each share
of FCB Common Stock would be converted are greater than those currently paid
on FCB Common Stock. Furthermore, for the first time, FCB Shareholders will
have substantial liquidity in their investment because, unlike FCB Common
Stock, NCBC Common Stock is listed and actively traded. The Merger also will
allow the FCB Shareholders to own shares in NCBC, which has significantly
greater financial resources and many more banking locations in more
diversified markets than FCB has at the present time and can expect to have in
the future. Additionally, after the Merger, the resources of NCBC should
enable the Bank to enhance its services to its customers and the northern
Georgia community in which it operates.
 
  The Board of Directors of NCBC also believes that the Merger is in the best
interests of NCBC and the NCBC shareholders. The Merger will allow NCBC to
establish a "hub" for NCBC's network of in-store supermarket branches in
Georgia, and should enable NCBC to facilitate expansion in the fast-growing
market of northern Georgia. In addition, FCB has a strong commercial loan base
which should enable NCBC to augment its small business and commercial lending
services in the region.
 
  FCB entered into the Merger Agreement after consideration of various factors
affecting the determination of the value for FCB Common Stock in the context
of a merger transaction, including among other factors the histories,
financial conditions, results of operations, and dividend records of FCB and
NCBC, and the business prospects of FCB, both separately and as a combined
entity with NCBC. In addition, the Board of Directors of FCB considered the
effect of the Merger on the employees, customers and suppliers of FCB and the
Bank and on the community where the Bank currently operates. The terms of the
Merger Agreement are the result of arms-length negotiations between FCB and
NCBC.
 
  Board of Directors' Recommendation. The Board of Directors of FCB believes
that the proposed Merger is in the best interests of FCB and the FCB
Shareholders and recommends that FCB Shareholders vote for approval and
adoption of the Merger Agreement. The Board of Directors of FCB approved the
Merger Agreement at its meeting on August 3, 1998, which was attended by eight
of ten FCB directors.
 
OPINION OF FINANCIAL ADVISOR TO FCB
 
  FCB retained Morgan Keegan & Company, Inc. ("Morgan Keegan") as its
financial advisor to render an opinion to the FCB Board of Directors
concerning the fairness, from a financial point of view, to FCB Shareholders
of the Exchange Ratio pursuant to the Agreement. Morgan Keegan was retained by
FCB on the basis of, among other things, its experience and expertise in the
bank and thrift industries. As part of its investment banking business, Morgan
Keegan is regularly engaged in the valuation of businesses and securities in
connection with mergers and acquisitions, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for various purposes.
 
  On August 7, 1998 Morgan Keegan delivered its written opinion to the Board
of Directors of FCB to the effect that, as of August 7, 1998 and based upon
and subject to certain matters stated in such opinion, the Exchange Ratio is
fair, from a financial point of view, to FCB Shareholders.
 
  The full text of the written opinion of Morgan Keegan, which sets forth the
assumptions made, matters considered and limitations on the review undertaken,
is attached hereto as Appendix II and is incorporated herein by reference. FCB
Shareholders are urged to read this opinion carefully in its entirety. Morgan
Keegan's opinion is directed only to the fairness to the FCB Shareholders,
from a financial point of view, of the Exchange Ratio and does not address any
other aspect of the Merger or related transactions and does not constitute a
recommendation to any stockholder as to how such stockholder should vote at
the Meeting. The summary of the opinion of Morgan Keegan set forth in this
Proxy Statement/Prospectus is qualified in its entirety by reference to the
full text of such opinion.
 
                                      12
<PAGE>
 
  In arriving at its opinion, Morgan Keegan reviewed the Merger Agreement and
held discussions with certain senior officers, directors and other
representatives and advisors of FCB and certain senior officers and other
representatives and advisors of NCBC concerning the businesses, operations and
prospects of FCB and NCBC. Morgan Keegan examined certain publicly available
business and financial information relating to FCB and NCBC as well as certain
financial forecasts and other data for FCB and NCBC which were provided to
Morgan Keegan by or otherwise discussed with the respective management teams
of FCB and NCBC, including information relating to certain strategic
implications and operational benefits anticipated from the Merger. Morgan
Keegan reviewed the financial terms of the Merger as set forth in the Merger
Agreement in relation to, among other things: current and historical market
prices and trading volumes of FCB and NCBC Common Stock; the historical and
projected earnings and operating data of FCB and NCBC; and the capitalization
and financial condition of FCB and NCBC. Morgan Keegan considered, to the
extent publicly available, the financial terms of certain other similar
transactions recently effected which Morgan Keegan considered relevant in
evaluating the Merger and analyzed certain financial, stock market and other
publicly available information relating to the businesses of other companies
whose businesses Morgan Keegan considered relevant in evaluating those of FCB
and NCBC. Morgan Keegan also considered the relative contributions of FCB and
NCBC to the combined company. In addition to the foregoing, Morgan Keegan
conducted such other analyses and examinations and considered such other
financial, economic and market criteria as Morgan Keegan deemed appropriate to
arrive at its opinion. Morgan Keegan noted that its opinion was necessarily
based upon information available, and financial, stock market and other
conditions and circumstances existing and disclosed, to Morgan Keegan as of
the date of its opinion.
 
  In conducting its review and rendering its opinion, Morgan Keegan assumed
and relied, without independent verification, upon the accuracy and
completeness of all financial and other information publicly available or
furnished to or otherwise reviewed by or discussed with Morgan Keegan. With
respect to financial forecasts and other information provided to or otherwise
reviewed by or discussed with Morgan Keegan, the management teams of FCB and
NCBC advised Morgan Keegan that such forecasts and other information were
reasonably prepared on a basis reflecting the best currently available
estimates and judgements of the respective management teams of FCB and NCBC as
to the future financial performance of FCB and NCBC and the strategic
implications and operational benefits anticipated from the Merger. Morgan
Keegan assumed, with the consent of the Board of Directors of FCB, that the
Merger will be accounted for as a pooling of interests in accordance with
generally accepted accounting principles and as a tax-free reorganization for
federal income tax purposes. Morgan Keegan did not express any opinion as to
what the value of NCBC Common Stock actually will be when issued pursuant to
the Merger or the price at which NCBC Common Stock will trade subsequent to
the Merger. In addition, Morgan Keegan did not make or obtain an independent
evaluation or appraisal of the assets or liabilities (contingent or otherwise)
of FCB or NCBC nor did Morgan Keegan make any physical inspection of the
properties or assets of FCB or NCBC. Morgan Keegan was not asked to consider,
and its opinion does not address, the relative merits of the Merger as
compared to any alternative business strategies that might exist for FCB or
the effect of any other transaction in which FCB might engage. Although Morgan
Keegan evaluated the Exchange Ratio from a financial point of view, Morgan
Keegan was not asked to and did not recommend the specific consideration
payable in the Merger, which was determined by FCB and NCBC through arms-
length negotiations. No other limitations were imposed by FCB on Morgan Keegan
with respect to the investigations made or procedures followed by Morgan
Keegan in rendering its opinion.
 
  The following is a summary of the principal analyses performed by Morgan
Keegan in connection with its opinion.
 
  Summary Transaction Analysis. Morgan Keegan reviewed the terms of the
proposed transaction, including the Exchange Ratio and the aggregate
transaction value. Morgan Keegan reviewed the implied value of the
consideration offered based upon a market price per share of $43.038 which is
the average of the closing price per share of NCBC Common Stock on the Nasdaq
National Market (as reported by The Wall Street Journal) during the five (5)
trading day period from April 3, 1998, through April 9, 1998. Such market
price of $43.038 was then further adjusted to reflect the NCBC two-for-one (2
for 1) common stock split effective on July 1, 1998 to render a split-adjusted
market price per share of $21.519. This indicates an implied value of $70.3327
per
 
                                      13
<PAGE>
 
share of FCB Common Stock (assuming 492,183 fully diluted outstanding shares
based on an exchange ratio of 3.2684 NCBC Common Stock shares for one share of
FCB Common Stock which includes any Common Stock Equivalents). The implied
aggregate transaction value is $34.62 million. Morgan Keegan calculated that
as of April 9, 1998, the aggregate transaction value represented 35.43% of the
total assets of FCB at March 31, 1998, 4.15x FCB's stated book value at March
31, 1998, and 22.94x FCB's earnings for the trailing twelve months ending
March 31, 1998.
 
  Contribution Analysis. Morgan Keegan reviewed certain historical financial
and operating information for FCB, NCBC and the pro forma combined entity
resulting from the Merger based on financial data reported by FCB and NCBC.
Morgan Keegan analyzed the relative balance sheet contribution of FCB and NCBC
for certain data to the combined company on a pro forma basis as of March 31,
1998. This analysis indicated that FCB would have contributed 1.9% to combined
total assets, 2.4% to combined loans (net of allowances for losses), 2.3% to
deposits and 2.2% to tangible equity. Morgan Keegan also analyzed the relative
income statement contribution of FCB and NCBC for certain data to the combined
company on a pro forma basis. This analysis indicated that FCB would have
contributed 2.9% to combined net interest income for the latest twelve months
("LTM") ended March 31, 1998, 2.0% to combined pretax income and 2.0% to
combined net income. At the Exchange Ratio of one share of FCB Common Stock
for 3.2684 shares of NCBC Common Stock, the holders of outstanding FCB Common
Stock would own approximately 1.5% of NCBC on a fully diluted basis.
 
  Comparable Company Analysis for FCB. Morgan Keegan reviewed and compared
certain financial information relating to FCB to corresponding financial
information, public market multiples and ratios for eight publicly traded
Georgia companies that it deemed to be comparable to FCB. The companies which
Morgan Keegan used for the purposes of this analysis were First Sterling Banks
Inc., Golden Isle Financial Holdings, Inc., Habersham Bancorp, Merit Holding
Corporation, PAB Bankshares, Inc., Savannah Bancorp, Inc., Southwest Georgia
Financial Corporation, and Summit Bank Corporation (collectively, the
"Comparable Companies"). Morgan Keegan calculated a range of market multiples
for the Comparable Companies by dividing market value as of August 4, 1998 by
each such company's LTM earnings per share ended March 31, 1998 and tangible
book value reported March 31, 1998. This analysis indicated that the price per
share/earnings multiples ("P/E") for LTM EPS ranged from 12.70x to 27.95x,
with a mean of 20.42x and a median of 19.83x. Using balance sheet data as of
March 31,1998, Morgan Keegan's analysis of the Comparable Companies indicated
market value multiples of tangible book value that ranged from 1.43x to 4.20x,
with a mean of 2.50x and a median of 2.50x. Given that FCB Common Stock is
thinly traded, Morgan Keegan did not calculate market value multiples for FCB.
For the LTM results ending March 31, 1998, Morgan Keegan also compared certain
ratios (including, among other things, return on latest assets; return on
latest equity; loan loss reserve to total loans; total equity capital to total
assets; and total loans to total deposits) of the Comparable Companies to FCB.
For the Comparable Companies, the analysis indicated a return on latest assets
range of 0.57% to 1.64%, with a mean of 1.24% and a median of 1.31%, compared
with a 1.54% for FCB; a return on latest equity range of 7.34% to 15.02%, with
a mean of 12.30% and a median of 12.77% for the Comparable Companies, compared
to 18.10% for FCB; and a loan loss reserve to total loans range of 1.13% to
1.69%, with a mean of 1.47% and a median of 1.54% for the Comparable
Companies, compared to a 1.82% for FCB. Additionally, the analysis indicated a
total equity capital to total assets range of 7.73% to 12.30%, with a mean of
9.97% and a median of 9.47% for the Comparable Companies, compared to 8.53%
for FCB; and a total loans to total deposits range of 64.79% to 95.63%, with a
mean of 75.79% and a median of 73.24% for the Comparable Companies, compared
to a 78.89% for FCB.
 
  Comparable Company Analysis for NCBC. Morgan Keegan reviewed and compared
certain financial information relating to NCBC to corresponding financial
information, public market multiples and ratios for eight publicly traded
Southeastern banking companies that it deemed to be comparable to NCBC. The
companies which Morgan Keegan used for purposes of this analysis were
BancorpSouth, Inc., CCB Financial Corporation, Centura Banks, Inc.,
Cullen/Frost Bankers, Inc., International Bancshares Corporation, One Valley
Bancorp, Inc. Trustmark Corporation, and Whitney Holding Corporation
(collectively, the "NCBC Comparable Companies"). Morgan Keegan calculated a
range of market multiples for the NCBC Comparable Companies by dividing
 
                                      14
<PAGE>
 
market value as of August 4, 1998 by each such company's EPS for the latest
twelve months ending March 31, 1998 and tangible book value as of March 31,
1998. This analysis indicated that the price per share/earnings multiples
("P/E") for LTM EPS ranged from 16.40x to 22.16x, with a mean of 18.77x and a
median of 17.95x, compared to a 30.16x for NCBC. Using balance sheet data
reported March 31, 1998, Morgan Keegan's analysis of the NCBC Comparable
Companies indicated market value multiples of tangible book value that ranged
from 2.07x to 3.74x, with a mean of 2.82x and a median of 2.45x, compared to
6.09x for NCBC. For the LTM results ending March 31, 1998, Morgan Keegan also
compared certain ratios (including, among other things, return on latest
assets; return on latest equity; loan loss reserve to total loans; total
equity capital to total assets; and total loans to total deposits) of the NCBC
Comparable Companies to NCBC. For the NCBC Comparable Companies, the analysis
indicated a return on latest assets range of 1.07% to 1.36%, with a mean of
1.19% and a median of 1.16%, compared to 1.50% for NCBC; a return on latest
equity range of 11.85% to 21.20% with a mean of 14.75% and a median of 13.47%
for the NCBC Comparable Companies, compared to 20.18% for NCBC; and a loan
loss reserve to total loans range of 1.34% to 2.08%, with a mean of 1.56% and
a median of 1.48% for the NCBC Comparable Companies, compared to a 1.64% for
NCBC. Additionally, the analysis indicated a total equity capital to total
assets range of 5.44% to 10.89%, with a mean of 8.39% and a median of 8.61%
for the NCBC Comparable Companies, compared to 7.41% for NCBC; and a total
loans to total deposits range of 43.72% to 86.72%, with a mean of 73.03% and a
median of 77.09% for the NCBC Comparable Companies, compared to 77.49% for
NCBC.
 
  Stock Trading Analysis. Morgan Keegan reviewed and analyzed the price
performance and the historical trading volume for NCBC's Common Stock.
 
  Morgan Keegan's analysis indicated that for the five-year period ending
December 31, 1997, the compounded annual growth rate for NCBC was 29.98%
compared to 31.34% for the Nasdaq Banking Stocks, 18.33% for the Nasdaq
Composite, 17.37% for the S&P 500, and 22.76% for the S&P Bank Composite.
 
  Additionally, Morgan Keegan compared recent trading volume in NCBC's Common
Stock to that of its NCBC Comparable Companies. During the four quarters
ending March 31, 1998, the quarterly trading volume as a percentage of average
outstanding diluted shares for the NCBC Comparable Companies ranged from 0.87%
to 20.73%, with a mean of 6.74% and a median of 6.12%. During the same period,
the quarterly trading volume as a percentage of average outstanding diluted
shares for NCBC ranged from 16.07% to 24.93%, with a mean of 20.83% and a
median of 21.16%. Morgan Keegan considers NCBC to be liquid and marketable.
 
  Morgan Keegan also examined recent transactions involving FCB's stock, which
is privately and relatively thinly traded. Morgan Keegan placed little weight
on the market price of FCB's stock in its analysis.
 
  Analysis of Selected Comparable Mergers and Acquisitions. In order to assess
market pricing for comparable mergers, Morgan Keegan reviewed overall merger
transactions in the banking industry. Morgan Keegan selected 32 transactions
occurring between July 1, 1997, and July 22, 1998, involving selling banks
located within the state of Georgia with total assets between $32 million and
$540 million. No transaction was considered identical to the Merger;
therefore, the medians of the overall transaction multiples were considered
more relevant than the multiples for any specific transaction. Morgan Keegan
calculated market value multiples of LTM net income ranging from 12.59x to
34.35x, with a mean of 21.24x and a median of 21.35x, latest reported book
value ranging from 1.14x to 5.59x, with a mean of 2.88x and a median of 2.72x
and latest reported total assets ranging from 11.6% to 60.6%, with a mean of
27.5% and a median of 25.4%. FCB's transaction multiples are 22.94x latest
twelve months earnings for the period ending March 31, 1998, 4.15x stated book
value as of March 31, 1998, and 35.4% of total assets as of March 31, 1998.
 
  No company or transaction used in the comparable companies and comparable
transactions analyses for comparative purposes is identical to FCB or the
Merger. Accordingly, an analysis of the results of the foregoing necessarily
involves complex considerations concerning differences in financial and
operating characteristics of the companies and other factors. Mathematical
analysis (such as determining the average or median) is not, in itself, a
meaningful method of using comparable company or transaction data.
 
                                      15
<PAGE>
 
  Discounted Cash Flow Analysis. Morgan Keegan performed a discounted cash
flow analysis of the projected cash flow available for dividends of FCB for
fiscal years 1998 through 2002, based on projections provided by FCB
management. Using this information, Morgan Keegan calculated a range of equity
values for FCB based on the sum of (a.) the present value of the cash flow
available for dividends to FCB and (b.) the present value of the estimated
terminal value for FCB assuming that it was sold at the end of fiscal year
2002. In performing its discounted cash flow analysis, Morgan Keegan assumed,
among other things, discount rates of 11.0% to 13.0% and terminal multiples of
net income of 14.0x to 16.0x. Those discount rates and terminal multiples
reflect Morgan Keegan's qualitative judgements concerning the specific risk
associated with such an investment and the historical and projected operating
performance of FCB. This analysis resulted in a range of equity values for FCB
of $26.95 million to $27.74 million, or $54.75 to $56.36 per share.
 
  The summary of the Morgan Keegan opinion set forth above does not purport to
be a complete description of the analyses performed by Morgan Keegan. The
preparation of a fairness opinion is not necessarily susceptible to partial
analysis or summary description. Morgan Keegan believes that its analyses and
the summary set forth above must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, or of the above
summary, without considering all factors and analyses, would create an
incomplete view of the process underlying the analyses set forth in the
opinion. In addition, Morgan Keegan may have deemed various assumptions more
or less probable than other assumptions, so that the ranges of valuations
resulting from any particular analysis described above should not be taken to
represent the actual value of FCB or the combined company.
 
  In performing its analyses, Morgan Keegan made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of FCB or NCBC. The
analyses performed by Morgan Keegan are not necessarily indicative of actual
values or actual future results, which may be significantly more or less
favorable than suggested by such analyses. Such analyses were prepared solely
as part of Morgan Keegan's analysis of the fairness, from a financial point of
view, of the consideration to be paid by NCBC. The analyses do not purport to
be appraisals or to reflect the prices at which a company might actually be
sold or the prices at which any securities may trade at the present time or at
any time in the future.
 
  FCB has agreed to pay Morgan Keegan a retainer fee of $20,000 and,
contingent upon the closing of the Merger, a success fee of 0.5% of the
aggregate Merger consideration pursuant to an engagement letter. FCB has also
agreed to reimburse Morgan Keegan for its reasonable out-of-pocket expenses
and to indemnify Morgan Keegan against certain liabilities, including
liabilities under the federal securities laws.
 
EXCHANGE OF CERTIFICATES REPRESENTING FCB COMMON STOCK
 
  Promptly after the Effective Time, NCBC shall cause Bank of New York, the
exchange agent for NCBC Common Stock (the "Exchange Agent"), to mail to each
holder of record of any of the issued and outstanding shares of FCB Common
Stock immediately prior to the Effective Time materials that will contain
instructions with respect to the surrender of certificates representing shares
of FCB Common Stock and the distribution of certificates representing shares
of NCBC Common Stock. Shares of FCB Common Stock will be surrendered to the
Exchange Agent.
 
  Upon surrender to the Exchange Agent of one or more certificates for shares
of FCB Common Stock for cancellation, together with properly completed
transmittal materials, the Exchange Agent will distribute to each FCB
Shareholder a certificate representing the shares of NCBC Common Stock into
which the holder's shares of FCB Common Stock have been converted, together
with all undelivered dividends or distributions in respect of such shares
(without interest thereon). Cash will be paid in lieu of the issuance of
fractional shares of NCBC Common Stock. FCB Shareholders will not be entitled
to receive interest on any such cash to be received in the Merger. See "--
General."
 
  Until they have surrendered their FCB Common Stock certificates for
exchange, FCB Shareholders will not be entitled to receive any dividends or
other distributions that may be declared and payable to holders of record of
NCBC Common Stock. Upon the surrender of FCB Common Stock certificates,
however, NCBC Common
 
                                      16
<PAGE>
 
Stock certificates (together with all such withheld dividends or other
distributions with respect to the certificates, without interest) and any
withheld cash payment for a fractional share interest will be delivered and
paid (without interest). Neither NCBC nor the Exchange Agent will be liable to
a FCB Shareholder for any NCBC Common Stock or dividends thereon delivered in
good faith to a public official in accordance with any state's abandoned
property, escheat, or other similar law. After the Effective Time,
certificates representing shares of FCB Common Stock converted in the Merger
into NCBC Common Stock will be deemed for all other corporate purposes to
evidence ownership of the shares of NCBC Common Stock into which they were
converted.
 
COVENANTS; CONDITIONS; REPRESENTATIONS AND WARRANTIES; AMENDMENT AND
TERMINATION
 
  FCB Covenants. Pursuant to the Merger Agreement, during the period from the
date of the Merger Agreement and continuing until the Effective Time, FCB has
agreed to operate its business only in the usual, regular and ordinary course
and has agreed not to take certain actions (unless expressly contemplated in
the Merger Agreement) without the prior written consent of NCBC, including,
among other things: (i) amending its Articles of Incorporation, Bylaws or
other governing instruments; (ii) incurring any additional debt obligation or
other obligation for borrowed money in excess of an aggregate of $100,000,
except in the ordinary course of business consistent with past practices, or
imposing, or suffering the imposition, on any asset of any lien or permitting
any such lien to exist on any of its assets; (iii) directly or indirectly
redeeming, repurchasing, or otherwise acquiring any of its capital stock; (iv)
declaring or paying any dividend, or making any other distribution in respect
of FCB's capital stock, with the exception of a cash dividend, which the
parties have agreed will be $.49 per share of FCB Common Stock, the
declaration date of which shall be on or before 30 days prior to the Effective
Time; provided, however, that the declaration and payment of such dividend
shall not (x) prevent the Merger from qualifying for pooling of interests
accounting treatment or (y) result in a total consolidated stockholder's
equity of FCB of less than $8,330,000; (v) issuing, selling, pledging,
encumbering, authorizing the issuance of, entering into any contract to issue,
sell, pledge, encumber or authorize the issuance of or otherwise permitting to
become outstanding any additional shares of FCB Common Stock or any other
capital stock of FCB except pursuant to its employee or non-employee director
stock option plans; (vi) adjusting, splitting, combining or reclassifying any
capital stock or issuing or authorizing the issuance of any other securities
in respect of or in substitution for shares of FCB Common Stock or selling,
leasing, mortgaging or otherwise disposing of or otherwise encumbering any
shares of capital stock of any subsidiary or any asset having a book value in
excess of $25,000, other than in the ordinary course of business for
reasonable and adequate consideration; (vii) except for purchases of certain
marketable securities, purchasing any securities or making any material
investment in any person other than a wholly owned subsidiary or otherwise
acquiring direct or indirect control over any other persons, except in the
ordinary course of business; (viii) making any significant change in any tax
or accounting methods or systems of internal accounting controls, except as
may be appropriate to conform to changes in tax laws or regulatory accounting
requirements or generally accepted accounting principles; or (ix) entering
into, modifying, amending or terminating any material contract or waiving,
releasing, compromising or assigning any material rights or claims, except in
accordance with past practice. FCB also has agreed not to take certain
enumerated actions relating to the conduct of its business or pertaining to
its employees and employee benefit arrangements.
 
  In the Merger Agreement, FCB has agreed to cooperate in the preparation and
filing of the Registration Statement and the distribution of this Proxy
Statement/Prospectus. The Board of Directors of FCB is required to recommend
(subject to compliance with their fiduciary duties as advised by counsel) to
the FCB Shareholders approval of the matters submitted for approval in
connection with the Merger. The Board of Directors and the officers are
obligated (subject to compliance with their fiduciary duties as advised by
counsel) to use their reasonable efforts to obtain the approval of the FCB
Shareholders of the Merger Agreement, and to take all appropriate actions to
cause the Merger to be consummated.
 
  Conditions to Consummation of the Merger. The obligations of FCB and NCBC to
consummate the Merger are conditioned upon the following: (i) approval of the
Merger Agreement by FCB Shareholders owning a majority of the outstanding
shares of FCB Common Stock under applicable law; (ii) approval of the Merger
by the FRB, and the absence of any objection by the United States Justice
Department and approval of the Merger
 
                                      17
<PAGE>
 
by the Georgia Department of Banking and Finance; (iii) each party shall have
obtained all consents required for the consummation of the Merger or for
preventing any default under any contract or permit, which if such consent is
not obtained or made would be reasonably likely to have a material adverse
effect; (iv) no court or governmental or regulatory authority shall have
enacted, issued, promulgated, enforced or entered any law or order that
prohibits, restricts or makes illegal consummation of the Merger; (v) no stop
orders suspending the effectiveness of the Registration Statement of which
this Proxy Statement/Prospectus is a part shall have been issued, no action,
suit, proceeding or investigations by the SEC to suspend the effectiveness
thereof shall have been initiated and be continuing, and all necessary
approvals under state securities laws or the Securities Act or the Exchange
Act relating to the issuance of trading of the shares of NCBC Common Stock
pursuant to the Merger shall have been received; and (vi) the shares of NCBC
Common Stock to be issued pursuant to the Merger shall have been approved for
listing on the Nasdaq National Market tier, subject to official notice of
issuance. Consummation of the Merger by the parties is subject to the further
conditions, including among others, that: (i) the representations and
warranties of FCB and NCBC contained in the Merger Agreement must be true and
correct in all material respects as of the Closing Date, and the various
covenants of FCB and NCBC must have been duly performed and complied with
pursuant to the Merger Agreement and (ii) NCBC and FCB must have received
certain legal opinions dated the Closing Date. In addition to the conditions
described in the preceding sentence, the obligation of NCBC to consummate the
Merger is subject the following conditions: (i) exclusive of gains or losses
on transactions in securities, total consolidated stockholders equity of FCB
at the Closing Date shall not be less than $8,330,000; (ii) FCB shall own,
free and clear of any liens, not less than 100.0% of the outstanding capital
stock of the Bank; (iii) from and after December 31, 1997, neither FCB nor the
Bank shall have consummated any extraordinary sale of assets nor any material
investment portfolio restructuring; and (iv) certain FCB officers shall have
entered into non-compete agreements with NCBC and the Bank.
 
  It is anticipated that the foregoing conditions will be complied with but
FCB and NCBC may waive any condition to their obligations to consummate the
transaction, except requisite approvals of shareholders and regulatory
authorities. The Merger Agreement may be terminated by any of the parties if
all of the conditions to closing have not been satisfied or waived on or
before November 30, 1998.
 
  Representations and Warranties. The Merger Agreement contains a number of
representations and warranties by NCBC and FCB. The material accuracy of all
those representations and warranties as of the Closing Date is a condition to
the obligation of each company to consummate the Merger. The representations
and warranties relate to matters such as the organization of each company, the
authority of each company to transact its business, to enter into the Merger
Agreement and to consummate the transactions contemplated by the Merger
Agreement, the capitalization of each company, the filing of certain reports
by each company with regulatory authorities and the presentation of
information contained in those reports, the absence of certain changes in
FCB's financial condition or business since December 31, 1997, the payment of
taxes and filing of tax returns, FCB's allowance for possible loan losses, the
absence of material litigation, the compliance with laws by each company, the
information provided by each company for use in the Registration Statement,
FCB's employee benefit plans and the employment contracts of FCB.
 
  Amendment and Termination. The Merger Agreement may be amended by agreement
between FCB and NCBC, except that no amendment reducing the consideration
received by FCB Shareholders may be made unless approved by the FCB
Shareholders. The Merger Agreement may be terminated by either FCB or NCBC
upon the failure of conditions to be met on or before November 30, 1998. In
such event, the Merger Agreement will be of no further force or effect, and
neither party will have any further liability to the other.
 
RESALE OF NCBC COMMON STOCK BY AFFILIATES
 
  NCBC Common Stock to be issued to FCB Shareholders in connection with the
Merger has been registered under the Securities Act and, upon consummation of
the Merger, will be freely transferable under the Securities Act, except for
shares issued to any person who may be deemed an "Affiliate" (as defined
below) of FCB within the meaning of Rule 145 under the Securities Act.
"Affiliates" are generally defined as persons who control, are controlled by,
or are under common control with FCB at the time of the Meeting (generally,
directors and certain
 
                                      18
<PAGE>
 
executive officers of FCB and major shareholders of FCB). Generally, all
shares of NCBC Common Stock received by such Affiliates may not be sold by
them until NCBC publishes at least one full calendar month of the combined
results of operations of NCBC and FCB.
 
  In addition, Affiliates of FCB may not sell their shares of NCBC Common
Stock acquired in connection with the Merger except pursuant to an effective
registration statement under the Securities Act covering such shares or in
compliance with Rule 145 or another applicable exemption from the registration
requirements of the Securities Act. In general, under Rule 145, for one year
following the Effective Time (the "Restricted Period"), an Affiliate (together
with certain related persons) is entitled to sell shares of NCBC Common Stock
acquired in connection with the Merger only through unsolicited "broker
transactions" or in transactions directly with a "market maker," as such terms
are defined in Rule 144 under the Securities Act. Additionally, the number of
shares that may be sold by an Affiliate (together with certain related persons
and certain persons acting in concert) within any three-month period during
the Restricted Period for purposes of Rule 145 may not exceed the greater of
(i) one percent of the outstanding shares of NCBC Common Stock or (ii) the
average weekly trading volume of such stock during the four calendar weeks
preceding such sale. Rule 145 is available to Affiliates only if NCBC remains
current with its information filings with the SEC under the Exchange Act.
Following the Restricted Period, an Affiliate may sell such NCBC Common Stock
free of such manner of sale or volume limitations, provided that NCBC was
current with its Exchange Act information filings and such Affiliate was not
then an Affiliate of NCBC. Two years after the Effective Time, an Affiliate
may sell shares of NCBC Common Stock without any restrictions so long as such
Affiliate was not and had not been for at least three months prior thereto, an
Affiliate of NCBC.
 
REGULATORY AND OTHER LEGAL CONSIDERATIONS
 
  The Merger is subject to approval by the FRB under the Bank Holding Company
Act of 1956, as amended (the "BHC Act"). The BHC Act provides that the FRB
will not approve a transaction (a) which would result in a monopoly, or which
would be in furtherance of any combination or conspiracy to monopolize or to
attempt to monopolize the business of banking in any part of the United States
or (b) the effect of which in any section of the country may be substantially
to lessen competition, or to tend to create a monopoly, or which in any other
manner would be in restraint of trade, unless the FRB finds that the
anticompetitive effects of the proposed transaction are clearly outweighed in
the public interest by the probable effect of the transaction in meeting the
convenience and needs of the community to be served. In conducting its review
of any application for approval, the FRB is required to consider the financial
and managerial resources and future prospects of the company or companies and
the banks concerned, and the convenience and needs of the community to be
served. The BHC Act also requires the FRB to notify the Attorney General of
the United States of the approval of any transaction. Any action brought under
the antitrust laws by the Attorney General (acting through the Department of
Justice) arising out of any transaction must be commenced by the Department of
Justice prior to the earliest date the transaction could be consummated,
which, with certain limited exceptions, is 30 days after the FRB approval. The
BHC Act further requires that consummation of approved acquisitions or mergers
be delayed for a period of not less than 30 days following the date of FRB
approval during which time complaining parties may obtain a review of the
FRB's order by filing a petition requesting that the order be set aside in the
United States Court of Appeals for the District of Columbia Circuit, or in the
United States Court of Appeals for the circuit in which the complaining party
has its principal place of business. If no action based on the antitrust laws
is commenced before the termination of the 30-day period, the acquisition or
merger may not be attacked thereafter in any judicial proceeding on the ground
that it alone and of itself constituted a violation of any antitrust laws
other than Section 2 of the Sherman Antitrust Act.
 
  The Merger is also subject to approval by the State of Georgia Department of
Banking and Finance (the "Department"). The procedure in Georgia is the same
to obtain permission to merge with a bank holding company and to acquire
control of a banking subsidiary. The Department will respond within 60 days
after receipt of a completed application. A completed application consists of
the following five items: (1) a copy of any form or documents regarding the
Merger filed with the FRB; (2) a letter from legal counsel to the applicant as
to whether any securities to be issued in the Merger are subject to
registration under either state or federal securities laws and that the
applicant is taking the necessary action to comply with any such applicable
laws;
 
                                      19
<PAGE>
 
(3) a draft copy of any proposed proxy statements or offering circulars or
letters prepared in connection with the Merger; (4) a copy of the most recent
independent audit, if any and if not already on file with the Department, of
the applicant's books and records, performed by independent public
accountants; and (5) proof of publication of a notice containing a brief
description of the Merger and notice of a 30 day opportunity for comment,
required by the Department not more than 30 days prior to filing the
application. The Department, in approving an application, will consider
factors deemed relevant by the FRB, including, but not limited to,
capitalization, competence of management, the convenience and needs of the
applicable community, resulting market share of the surviving entity and
competitive factors.
 
  The BHC Act discussed above provides for the publication of notices and the
administrative hearings relating to the federal or state filings noted above
and permits interested parties to intervene in the proceedings. If interested
parties intervene, administrative and judicial proceedings relating to both
federal and state filings could substantially delay the regulatory approvals
required for consummation of the Merger.
 
  The management of NCBC does not believe that the consummation of the Merger
will violate any antitrust or applicable state laws, but there can be no
assurance that the FRB, the Department of Justice or other regulatory
authorities will concur in this assessment.
 
ACCOUNTING TREATMENT
 
  NCBC will account for the Merger as a pooling of interests. Under the
pooling of interests method of accounting, the historical basis of the assets
and liabilities of NCBC and FCB will be combined at the Effective Time and
carried forward at their previously recorded amounts, the stockholders' equity
accounts of NCBC and FCB will be combined on the consolidated balance sheet of
NCBC and no goodwill or other intangible assets will be created. Consolidated
financial statements of NCBC issued after the Merger will be restated
retroactively to reflect the consolidated operations of NCBC and FCB as if the
Merger had taken place prior to the periods covered by such consolidated
financial statements.
 
FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a summary of certain federal income tax consequences of the
Merger and the exchange by the holders of FCB Common Stock of such shares for
shares of NCBC Common Stock. This discussion does not address all aspects of
taxation that may be relevant to particular FCB Shareholders in light of their
personal investment or tax circumstances, or to certain types of FCB
Shareholders (including insurance companies, financial institutions, broker-
dealers, foreign corporations, persons who receive stock through the exercise
of stock options or otherwise as compensation for services rendered and
persons who are not citizens or residents of the United States) subject to
special treatment under the federal income tax laws, nor does it discuss any
state, local or foreign tax considerations. Accordingly, each FCB Shareholder
is urged to consult his or her own tax advisor as to the specific tax
consequences of the Merger, including the applicable federal, state, local and
foreign tax consequences of the Merger.
 
  Neither NCBC nor FCB has requested or will receive an advance ruling from
the Internal Revenue Service (the "Service") as to the federal income tax
consequences of the Merger. Instead, King & Spalding, counsel to NCBC, will
deliver an opinion to FCB and NCBC relating to certain federal income tax
consequences of the Merger. Such opinion will be based upon certain
representations of fact provided by NCBC and FCB. Such representations of fact
will not be independently verified by King & Spalding. Such opinion will be
also based upon the Code, regulations thereunder, administrative rulings and
practice by the Service, and judicial authority, in each case existing at the
time such opinion is delivered. Any change in applicable law or pertinent
facts could affect the continuing validity of such opinion and this
discussion. In addition, a tax opinion is not binding upon the Service, and
there can be no complete assurance, and none is hereby given, that the Service
will not take a position which is contrary to one or more positions reflected
in the tax opinion, or that such opinion will be upheld by the courts if
challenged by the Service. However, NCBC and FCB have agreed in the Merger
Agreement not to take any action which would disqualify the Merger as a
reorganization which is tax-free to the FCB Shareholders pursuant to Section
368(a) of the Code. Based on the foregoing, it is anticipated that the tax
 
                                      20
<PAGE>
 
opinion will state, among other matters, that: (i) the Merger will constitute
a reorganization within the meaning of Section 368(a) of the Code, and NCBC
and FCB will each be a party to the reorganization within the meaning of
Section 368(b) of the Code; (ii) no gain or loss will be recognized by NCBC or
FCB as a result of the Merger; (iii) no gain or loss will be recognized by the
FCB Shareholders upon the exchange of FCB Common Stock for NCBC Common Stock
pursuant to the Merger (except with respect to cash received in lieu of
fractional shares of NCBC Common Stock), or by the holders of FCB Options upon
the conversion of such options into rights with respect to NCBC Common Stock;
(iv) the receipt of cash in lieu of fractional shares of NCBC Common Stock
will be treated as if fractional shares were distributed as part of the
exchange and then were redeemed by NCBC; (v) a FCB Shareholder who perfects
his appraisal rights under Georgia law and who receives payment in cash for
the "fair value" of his shares of FCB Common Stock will be treated as having
exchanged such shares for cash in a redemption subject to Section 302 of the
Code, and the FCB Shareholder generally will recognize capital gain or loss in
such exchange equal to the difference between the cash received and the tax
basis of such shares; (vi) the aggregate tax basis of the shares of NCBC
Common Stock received by a FCB Shareholder pursuant to the Merger will be the
same as the aggregate tax basis of the shares of FCB Common Stock surrendered
in exchange therefor, excluding any basis allocable to a fractional share of
NCBC Common Stock for which cash is received; and (vii) the holding period of
the shares of NCBC Common Stock received by a FCB Shareholder will include the
holding period or periods of the shares of FCB Common Stock exchanged
therefor, provided that the shares of FCB Common Stock are held as a capital
asset within the meaning of Section 1221 of the Code at the Effective Time.
 
  EACH HOLDER OF SHARES OF FCB COMMON STOCK IS URGED TO CONSULT SUCH HOLDER'S
PERSONAL TAX AND FINANCIAL ADVISORS AS TO THE SPECIFIC FEDERAL INCOME TAX
CONSEQUENCES TO SUCH HOLDER, BASED ON SUCH HOLDER'S OWN PARTICULAR STATUS AND
CIRCUMSTANCES, AND ALSO AS TO ANY STATE, LOCAL, FOREIGN OR OTHER TAX
CONSEQUENCES ARISING OUT OF THE MERGER.
 
  THE DISCUSSION SET FORTH ABOVE DOES NOT ADDRESS THE STATE, LOCAL OR FOREIGN
TAX ASPECTS OF THE MERGER. THE DISCUSSION IS BASED ON CURRENTLY EXISTING
PROVISIONS OF THE CODE, EXISTING AND PROPOSED TREASURY REGULATIONS THEREUNDER
AND CURRENT ADMINISTRATIVE RULINGS AND COURT DECISIONS. ALL OF THE FOREGOING
ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING VALIDITY
OF THIS DISCUSSION. EACH FCB SHAREHOLDER SHOULD CONSULT HIS OR HER OWN TAX
ADVISOR WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO HIM OR
HER, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN TAX
LAWS.
 
EXPENSES
 
  All expenses incurred by or on behalf of the parties in connection with the
Merger Agreement and the transactions contemplated by the Merger Agreement are
to be borne by the party incurring the expense, except that NCBC and FCB shall
bear and pay the filing fees payable in connection with the Registration
Statement of which this Proxy Statement/Prospectus is a part and this Proxy
Statement/Prospectus and the printing costs incurred in connection with the
printing of such Registration Statement and this Proxy Statement/Prospectus
based on the relative asset sizes of the parties at December 31, 1997.
 
STOCK EXCHANGE LISTING
 
  NCBC Common Stock is listed on the Nasdaq National Market tier. NCBC will
use its best efforts to cause the shares of NCBC Common Stock to be issued
under the Merger Agreement to be approved for listing on the Nasdaq National
Market tier, subject to official notice of issuance, prior to the Effective
Time.
 
NO SOLICITATION OF TRANSACTIONS; BREAK-UP FEE
 
  Pursuant to the Merger Agreement, neither FCB nor any affiliate of FCB nor
any representatives thereof may directly or indirectly solicit or knowingly
encourage any exchange offer or any proposal for a merger,
 
                                      21
<PAGE>
 
consolidation, acquisition of all or substantially all, but in no event less
than 90%, of the outstanding FCB Common Stock and, concurrently, not less than
100% of the outstanding common stock of the Bank by any person. Furthermore,
except to the extent necessary to comply with the fiduciary duties of FCB's
Board of Directors, neither FCB nor any affiliate or representative of FCB
may, pursuant to the Merger Agreement, furnish any non-public information that
it is not legally obligated to furnish, negotiate with respect to, or enter
into, or agree to enter into any contract with respect to any Acquisition
Proposal, but FCB may communicate information about such an Acquisition
Proposal to its shareholders if and to the extent that it is required to do so
in order to comply with its legal obligations as advised by counsel. FCB has
agreed pursuant to the Merger Agreement to promptly notify NCBC in the event
that it receives any inquiry or proposal relating to any such transaction.
Pursuant to the Merger Agreement, FCB has further agreed to pay or cause to be
paid to NCBC the sum of $500,000 prior to entering into a letter of intent,
agreement in principle, or definitive agreement (whether or not considered
binding, nonbinding, conditional or unconditional) with any third party with
respect to an Acquisition Proposal, or supporting or indicating an intent to
support an Acquisition Proposal.
 
DISSENTERS' RIGHTS
 
  If the Merger and the transactions contemplated thereby are consummated, any
FCB Shareholder who properly perfects his statutory dissenters' rights of
appraisal in accordance with Article 13 of the GBCC ("Article 13") has the
right to receive in cash the fair value of such FCB Shareholder's shares of
FCB Common Stock determined immediately prior to the Merger, excluding any
appreciation or depreciation in value in anticipation of the Merger. The
following is a summary of Article 13 and the procedures for FCB Shareholders
dissenting from the Merger and perfecting such dissenters' rights of
appraisal. This summary is qualified in its entirety by reference to Article
13, which is reprinted in full as Appendix III to this Proxy
Statement/Prospectus. Appendix III should be reviewed carefully by any FCB
Shareholder who wishes to perfect such statutory dissenters' rights. FAILURE
TO STRICTLY COMPLY WITH THE PROCEDURES SET FORTH IN ARTICLE 13 WILL RESULT IN
THE LOSS OF DISSENTERS' RIGHTS.
 
  To exercise appraisal rights under Article 13, a holder of FCB Common Stock
must (i) deliver to NCBC before the taking of the vote of FCB Shareholders on
the Merger Agreement written notice of his intent to demand payment for his
shares if the Merger is effected, and (ii) not vote his shares in favor of the
Merger Agreement. A FCB Shareholder who does not satisfy these two
requirements is not entitled to payment for his shares under Article 13. In
addition, any FCB Shareholder who returns a signed proxy but fails to provide
instructions as to the manner in which such shares are to be voted will be
deemed to have voted in favor of the Merger Agreement and will not be entitled
to assert dissenters' rights of appraisal.
 
  A FCB Shareholder may assert dissenters' rights as to fewer than all the
shares registered in his name only if he dissents with respect to all shares
beneficially owned by any one beneficial FCB Shareholder and he notifies NCBC
in writing of the name and address of each person on whose behalf he asserts
dissenters' rights. The rights of such a partial dissenter are determined as
if the shares as to which he dissents and his other shares are registered in
the names of different FCB Shareholders.
 
  If the Merger Agreement is approved at the Meeting, NCBC must deliver a
written dissenters' notice (the "Dissenters' Notice) to all Shareholders who
satisfied the notice requirements of Article 13. The Dissenters' Notice must
be sent within 10 days after the Effective Time and must (i) state where the
demand for payment must be sent and where and when certificates for shares
must be deposited, (ii) inform holders of uncertificated shares to what extent
transfer of those shares will be restricted after the demand for payment is
received, (iii) set a date by which NCBC must receive the demand for payment
(which date may not be fewer than 30 nor more than 60 days after the
Dissenters' Notice is delivered), and (iv) be accompanied by a copy of Article
13.
 
  A record FCB Shareholder who receives the Dissenters' Notice must demand
payment and deposit his certificates in accordance with the Dissenters'
Notice. Such FCB Shareholder will retain all other rights of a FCB Shareholder
until those rights are canceled or modified by the consummation of the Merger.
A record FCB
 
                                      22
<PAGE>
 
Shareholder who does not demand payment or deposit his share certificates
where required, each by the date set in the Dissenters' Notice, is not
entitled to payment for his shares under Article 13.
 
  Within 10 days of the later of the Effective Time or receipt of a payment
demand, NCBC must offer to pay each dissenting FCB Shareholder who complied
with Article 13 the amount NCBC estimates to be the fair value of his shares,
plus accrued interest from the Effective Time. Such offer of payment must be
accompanied by (i) certain recent NCBC financial statements, (ii) NCBC's
estimate of the fair value of the shares and interest due, (iii) an
explanation of how the interest was calculated, (iv) a statement of the
dissenter's right to demand payment under Article 13, and (v) a copy of
Article 13. If the FCB Shareholder accepts NCBC's offer by written notice to
NCBC within 30 days after NCBC's offer, NCBC must make payment within 60 days
after the later of the making of the offer or the Effective Time.
 
  If the Merger is not consummated within 60 days after the date set for
demanding payment and depositing share certificates, NCBC must return the
deposited certificates. If, after such return, the Merger is consummated, NCBC
must send a new Dissenters' Notice and repeat the payment procedure described
above.
 
  A dissenting FCB Shareholder may notify NCBC in writing of his own estimate
of the fair value of his shares and the interest due, and may demand payment
of his estimate, if (i) he believes that the amount offered by NCBC is less
than the fair value of his shares or that the interest due has been calculated
incorrectly or (ii) NCBC, having failed to consummate the Merger, does not
return the deposited certificates within 60 days after the date set for
demanding payment. A dissenting FCB Shareholder waives his right to demand
payment unless he notifies NCBC of his demand in writing within 30 days after
NCBC makes or offers payment for his shares. If NCBC does not offer payment
within 10 days of the later of the Effective Time or receipt of a payment
demand, then (i) the FCB Shareholder may demand the financial statements and
other information of NCBC, and NCBC must provide such information within 10
days after receipt of the written demand, and (ii) the FCB Shareholder may
notify NCBC of his own estimate of the fair value of his shares and the amount
of interest due, and may demand payment of that estimate.
 
  If a demand for payment by a FCB Shareholder remains unsettled, NCBC must
commence a nonjury equity valuation proceeding in the appropriate court, as
specified in Article 13, within 60 days after receiving the payment demand and
must petition the court to determine the fair value of the shares and accrued
interest. If NCBC does not commence the proceeding within 60 days, NCBC is
required to pay each dissenting FCB Shareholder whose demand remains
unsettled, the amount demanded. NCBC is required to make all dissenting FCB
Shareholders whose demands remain unsettled parties to the proceeding and to
serve a copy of the petition upon each dissenting FCB Shareholder. The court
may appoint appraisers to receive evidence and to recommend a decision on fair
value. Each dissenting FCB Shareholder made a party to the proceeding is
entitled to judgment for the fair value of his shares plus interest to the
date of judgment.
 
  In an appraisal proceeding commenced under Article 13, the court must
determine the costs of the proceeding, excluding fees and expenses of
attorneys and experts for the respective parties, and must assess those costs
against NCBC, except that the court may assess the costs against all or some
of the dissenting FCB Shareholders to the extent the court finds they acted
arbitrarily, vexatiously, or not in good faith in demanding payment under
Article 13. The court also may assess the fees and expenses of attorneys and
experts for the respective parties against NCBC if the court finds NCBC did
not substantially comply with the requirements of Article 13, or against
either NCBC or a dissenting FCB Shareholder if the court finds that such party
acted arbitrarily, vexatiously, or not in good faith with respect to the
rights provided by Article 13.
 
  If the court finds that the services of the attorneys for any dissenting FCB
Shareholder were of substantial benefit to other dissenting FCB Shareholders
similarly situated, and that the fees for those services should not be
assessed against NCBC, the court may award those attorneys reasonable fees out
of the amounts awarded the dissenting FCB Shareholders who were benefited. No
action by any dissenting FCB Shareholder to enforce dissenters' rights may be
brought more than three years after the Effective Time, regardless of whether
notice of the Merger and of the right to dissent was given by NCBC in
compliance with the provisions of Article 13.

               COMPARISON OF RIGHTS OF FCB AND NCBC SHAREHOLDERS
 
  FCB is incorporated under the laws of the State of Georgia, and NCBC is
incorporated under the laws of the State of Tennessee. FCB Shareholders, whose
rights as shareholders are currently governed by Georgia law and the FCB
Articles of Incorporation and Bylaws, will become, upon consummation of the
Merger, shareholders of NCBC. Their rights as shareholders of NCBC will be
governed by Tennessee law and the NCBC Charter and Bylaws. Certain differences
between the rights of FCB Shareholders and NCBC Shareholders are summarized
below. The summary does not purport to be a complete statement of the rights
of FCB Shareholders as compared with the rights of NCBC Shareholders. The
identification of specific differences is not meant to indicate that other
equally or more significant differences do not exist. The summary is qualified
in its entirety by reference to the Tennessee General Corporation Act, the
Tennessee Business Corporation Act (effective October 1, 1987), the Georgia
Business Corporation Code (the "GBCC"), and the respective Articles of
Incorporation or Charter and Bylaws of the two corporations.
 
  Changes in Control. Certain provisions of the NCBC Charter and Bylaws may
have the effect of preventing, discouraging or delaying any change of control
of NCBC. These provisions include the authority to issue preferred stock with
such rights and privileges as the Board of Directors may deem appropriate from
time to time, provisions for the classification of the NCBC Board of
Directors, and provisions relating to certain business combinations. The
authority of the Board of Directors to issue preferred stock with such rights
and privileges, including voting rights, dividend, redemption and conversion
rights, may enable the Board of Directors to prevent a change in control
despite a shift in ownership of NCBC Common Stock. The classification of the
NCBC Board of Directors, pursuant to which one-third of the directors of NCBC
are elected each year for a three-year term, and the special Board of
Directors voting provisions in connection with transactions with Interested
Shareholders (as described below), may delay the ability of dissatisfied NCBC
Shareholders or anyone who obtains a controlling interest in NCBC Common Stock
to elect a new Board of Directors and to exercise control of NCBC. The
provision of the NCBC Charter relating to certain business combinations (the
"Fair Price Provisions") may have the effect of deterring or making more
difficult a change in control or acquisition of NCBC.
 
  The Fair Price Provisions contained in the NCBC Charter are summarized
below. The Fair Price Provisions require that certain business combinations
involving an Interested Shareholder (as defined in the NCBC Charter to include
a person who beneficially owns (as defined in the NCBC Charter) 5% or more of
NCBC Common Stock) be approved by the holders of at least two-thirds of the
outstanding shares of NCBC Common Stock, unless two-thirds of the entire NCBC
Board of Directors approves the transaction and certain minimum price criteria
and procedural safeguards are satisfied. These transactions include any merger
or consolidation of NCBC into an Interested Shareholder or any affiliates
thereof, any sale of more than $5 million in assets of NCBC to an Interested
Shareholder or any affiliates thereof, any recapitalization or
reclassification of NCBC securities or similar transaction increasing the
percentage ownership by an Interested Shareholder or any proposal for the
liquidation of NCBC.
 
  The Fair Price Provisions require that a business combination involving any
Interested Shareholder which does not receive the required shareholder vote
must meet certain fair price criteria. Those criteria require, among other
things, that the aggregate amount of the cash and fair market value of the
consideration other than cash to be received for each share of NCBC be at
least equal to the highest of the following computations:
 
    (i) the highest per share price (including brokerage commissions,
  transfer taxes and soliciting dealers' fees) paid or agreed to be paid by
  the Interested Shareholder for any shares of NCBC Common Stock acquired by
  it (1) within the four-year period immediately prior to the first public
  announcement of the proposed business combination (the "Announcement Date")
  or (2) in the transaction in which it became an Interested Shareholder,
  whichever is higher, or
 
    (ii) the fair market value per share of NCBC Common Stock on the
  Announcement Date or on the date on which the Interested Shareholder became
  an Interested Shareholder.
 
 
                                      24
<PAGE>
 
  In addition, the consideration paid for NCBC Common Stock in a business
combination must be either cash or the same form of consideration paid by the
Interested Shareholder to acquire the largest number of shares of NCBC Common
Stock previously acquired by it.
 
  The Fair Price Provisions are designed to discourage attempts to take over
NCBC by utilizing two-tier pricing tactics or by acquiring less than all of
NCBC's outstanding shares. In recent years there have been increasing numbers
of non-negotiated attempts to take over publicly owned corporations. These
attempts typically involve the accumulation of a substantial block of the
target corporation, followed by a merger or other reorganization of the
acquired company on terms determined entirely by the purchaser. The terms of
these attempts may include two-tier pricing, which is the practice of paying
cash to acquire a controlling interest in a company and acquiring the
remaining equity interest by paying the remaining shareholders a price that is
lower than the price paid to acquire the controlling interest or by utilizing
a different form of consideration for payment to the remaining shareholders
than was used to purchase the controlling interest.
 
  While the terms of such a non-negotiated takeover could be fair to NCBC
Shareholders, negotiated transactions may result in more favorable terms to
NCBC Shareholders because of factors such as the timing of the transaction,
the tax effects on the shareholders and the fact that the nature and amount of
the consideration paid to all shareholders will be negotiated by the parties
at arms-length rather than dictated by the purchaser.
 
  Although the federal securities laws and regulations applicable to certain
of the business combinations covered by the Fair Price Provisions require that
disclosure be made to shareholders of the terms of such a transaction, these
laws do not assure shareholders that the financial terms of the business
combination will be fair to them or that they can effectively prevent its
consummation. The Fair Price Provisions are intended to address some of the
effects of these gaps in federal and state laws and prevent some of the
potential inequities of certain acquisitions that involve two or more steps.
The Fair Price Provisions require that, in order to complete a business
combination that is not approved by a two-thirds vote of the holders of at
least 75% of the outstanding NCBC Common Stock, an Interested Shareholder must
obtain the affirmative vote of two-thirds of NCBC Board of Directors, or meet
the minimum price and procedural requirements of the Fair Price Provisions.
 
  Due to the difficulties of complying with the requirements of the Fair Price
Provisions, the Fair Price Provisions generally may discourage attempts to
acquire control of NCBC. As a result, holders of NCBC Common Stock may be
deprived of an opportunity to sell their shares at a premium above the market
price. In addition, the Fair Price Provisions would give veto power to the
holders of a minority of NCBC Common Stock with respect to certain business
combinations that are opposed by more than one-third of the NCBC Board of
Directors and which do not meet the Fair Price Provisions, but which a
majority of shareholders may believe to be desirable and beneficial. Moreover,
in any such business combination not receiving the requisite approval of NCBC
Shareholders or of directors, the minimum price provisions of the Fair Price
Provisions, while providing objective pricing criteria, could be arbitrary and
not indicative of value.
 
  The FCB Articles of Incorporation and Bylaws also contain certain provisions
which may have the effect of preventing, discouraging or delaying a change in
control of FCB. Like NCBC, the Board of Directors of FCB is staggered. The
Board is divided into three classes, with each class as nearly equal in number
as possible. One-third of the directors of FCB are elected each year for a
three-year term.
 
  The FCB Articles of Incorporation also contain a provision requiring the
affirmative vote of the holders of at least two-thirds of the outstanding
shares of the corporation entitled to vote thereon to approve any merger or
consolidation of the corporation with or into any other corporation and any
sale, lease, exchange or disposition of all or substantially all of the assets
of the corporation to any other corporation, person, or entity if such other
corporation, person, or entity which is a party to such transaction is the
beneficial owner, directly or indirectly, of 5% or more of the issued and
outstanding shares of the corporation entitled to vote in an election of
directors.
 
  The FCB Board of Directors, when evaluating an offer of another party (a) to
make a tender offer or exchange offer for any equity security of the
corporation, (b) to merge or consolidate any other corporation with
 
                                      25
<PAGE>
 
the corporation, or (c) to purchase or otherwise acquire all or substantially
all of the assets of the corporation, shall, in determining what is in the
best interest of the corporation and its shareholders, consider all relevant
factors, including (i) the short-term and long-term social and economic
effects on the employees, customers, shareholders and other constituents of
the corporation and its subsidiaries, and on the communities within which the
corporation and its subsidiaries operate; and (ii) the consideration being
offered by the other party in relation to the then-current value of the
corporation in a freely negotiated transaction and in relation to the Board of
Directors' then-estimate of the future value of the corporation as an
independent entity.
 
  Amendment of Charter or Articles of Incorporation. Tennessee law requires a
majority vote of the outstanding shares of the corporation entitled to vote to
amend its charter. The NCBC Charter, however, requires an affirmative vote by
at least two-thirds of the shares entitled to vote (other than shares held by
an Interested Shareholder) to alter or amend any provisions of the Charter
unless the Board of Directors, by a two-thirds majority, submits the proposed
amendment to a vote of shareholders in which circumstance a majority vote of
shareholders is needed.
 
  The GBCC also requires a majority vote of the outstanding shares of the
corporation entitled to vote to amend its articles of incorporation. The FCB
Articles of Incorporation state that a different voting requirement is
necessary to amend or rescind some of the articles. The FCB Articles of
Incorporation provide that unless two-thirds of the directors in office shall
approve the proposed change, the affirmative vote of the holders of at least
two-thirds of the outstanding stock of the corporation that are entitled to
vote in an election of directors is required to amend or rescind the articles
which authorize (i) a staggered board of directors, (ii) limitation of the
liability of directors, (iii) approval of a merger or consolidation with
certain shareholders, and (iv) the factors the board must use when evaluating
an offer by another party to make a tender offer or exchange offer, or to
merge or consolidate another corporation with FCB. Additionally, a vote of 80%
of the outstanding shares is required to amend the article authorizing removal
of a director.
 
  Certain Voting Rights. Tennessee law requires approval of any merger,
consolidation or sale of substantially all the assets of a corporation (except
for a surviving corporation in certain exempted mergers) by a vote of a
majority of the outstanding shares of the corporation entitled to vote, unless
the corporation's charter requires approval by a greater percentage. Georgia
law requires shareholders eligible to vote to approve the merger or share
exchange by a majority of the votes entitled to be cast.
 
  As described more fully above, the NCBC Charter and the FCB Articles of
Incorporation require a special shareholder vote to approve certain business
combinations, including mergers, consolidations and sales of assets, involving
certain shareholders.
 
  Dividends. A Tennessee corporation may pay dividends, if authorized by the
Board of Directors, unless, after giving effect to the dividend, (i) the
corporation would not be able to pay its debts as they become due in the usual
course of business or (ii) the corporation's total assets would be less than
the sum of its total liabilities plus (unless the charter permits otherwise)
the amount necessary to satisfy, upon dissolution, the rights of shareholders
whose preferential rights are superior to those receiving the distribution if
the corporation were dissolved at the time of the distribution. The NCBC
Charter authorizes distributions in accordance with Section 48-16-401 of the
Tennessee Business Corporation Act.
 
  The GBCC is similar in all material respects to Tennessee law. The FCB
Articles of Incorporation authorize the FCB Board of Directors to declare
dividends out of capital surplus.
 
  Boards of Directors. As permitted by Tennessee law, the NCBC Bylaws divide
the NCBC Board of Directors into three classes serving staggered three-year
terms, with the terms of one class of directors to expire each year. The
classification of the NCBC Board of Directors means that approximately one-
third of the NCBC Board of Directors is elected each year, with the result
that it would take two annual meetings of NCBC Shareholders to change the
majority of the members constituting the NCBC Board of Directors. The
classification of directors has the effect of making it more difficult to
change the composition of the board of
 
                                      26
<PAGE>
 
directors. A classified board of directors can help promote the continuity and
stability of management and policies because a majority of the directors at
any given time will have prior experience as directors.
 
  In addition, the NCBC Bylaws provide that any or all of the NCBC directors
may be removed from office at any time with or without cause, but only by the
affirmative vote of at least two-thirds of the shares entitled to vote.
 
  Under the GBCC, the articles of incorporation may allow for staggering the
terms of directors by dividing the total number of directors into two or three
groups, with each group containing one-half or one-third of the total. In
addition, the GBCC provides that, except in certain circumstances, any or all
of the board of directors of a Georgia corporation may be removed with or
without cause by the holders of a majority of the shares then entitled to vote
at an election of directors at a meeting called expressly for that purpose.
The FCB Articles of Incorporation and Bylaws provide for a staggered Board of
Directors. The Board is divided into three classes, with each class as nearly
equal in number as possible. One-third of the directors of FCB are elected
each year for a three-year term. The FCB Articles of Incorporation and Bylaws
provide that any director may be removed from office, at a meeting with
respect to which notice of such purpose is given, (a) without cause, only upon
the affirmative vote of 80% of the issued and outstanding shares of the
corporation, and (b) with cause, only upon the affirmative vote of the holders
of a majority of the issued and outstanding shares of the corporation.
 
  Special Meetings of Shareholders. Tennessee law provides that the Board of
Directors, any person authorized by the charter or bylaws, or unless the
charter provides otherwise, the holder of at least 10% of the votes entitled
to be cast may call a special meeting of shareholders. NCBC Bylaws provide
that a special meeting of NCBC Shareholders may be called by the Chairman of
the Board, the Board of Directors, or upon the written request of the holders
of not less than 10% of the votes entitled to be cast of NCBC Common Stock.
 
  The GBCC permits the board of directors, persons authorized by the articles
of incorporation or bylaws and holders of 25%, or such greater or lesser
percentages as may be provided in the articles of incorporation or bylaws, of
a all votes entitled to be cast on the proposed corporate action to call a
special meeting. The FCB Bylaws provide that a special meeting may be called
by any one or more shareholders holding an aggregate of 25% of the outstanding
capital stock of FCB.
 
  Dissenters' Rights. Under Tennessee law, the shareholders of a corporation
that is being merged into or is selling all or substantially all its assets to
another corporation have the right to dissent from the action and have a
Tennessee court determine the statutory fair value of their shares. Under the
GBCC, the shareholders of a corporation that is party to a merger have the
right to dissent from the action and have a Georgia court determine the fair
value of their shares. See "The Merger--Dissenters' Rights."
 
  Preemptive Rights. Unless the charter of a Tennessee corporation provides
otherwise, Tennessee law states that shareholders of a Tennessee corporation
do not have preemptive rights to acquire proportional amounts of the
corporation's unissued shares upon decision of the board of directors to issue
them. The NCBC Charter provides that no holder of any class of NCBC common
stock will have preemptive rights.
 
  The GBCC is substantially similar to Tennessee law. The FCB Articles of
Incorporation provide that no holder of shares of FCB common stock shall have
preemptive rights.
 
  Indemnification/Limitation on Liability. Under both Tennessee and Georgia
law, a corporation may indemnify an individual who is a party to a proceeding
because he or she is or was a director or officer against liability incurred
in the proceeding if such individual conducted himself or herself in good
faith and such individual reasonably believed (i) in the case of conduct in
his or her official capacity, that such conduct was in the best interests of
the corporation, (ii) in all other cases, that such conduct was at least not
opposed to the best interests of the corporation and (iii) in the case of any
criminal proceeding, that the individual had no reasonable cause to believe
such conduct was unlawful. A corporation may not indemnify a director or
officer (i) in connection with a proceeding by or in the right of the
corporation, except for reasonable expenses incurred in
 
                                      27
<PAGE>
 
connection with the proceeding if it is determined that the director or
officer has met the relevant standard of conduct under Tennessee and Georgia
law or (ii) in connection with any proceeding with respect to conduct for
which he or she was adjudged liable on the basis that personal benefit was
improperly received by him or her, whether or not involving action in his or
her official capacity. A corporation must indemnify a director or officer who
was wholly successful, on the merits or otherwise, in the defense of any
proceeding to which he or she was a party because he or she was a director or
officer of the corporation against reasonable expenses incurred by the
director or officer in connection with the proceeding.
 
  The NCBC Bylaws provide for indemnification in accordance with Tennessee law
for officers and directors of NCBC and their testators and intestators. The
FCB Bylaws provide for indemnification in accordance with Georgia Law for
directors, officers, employees or agents of FCB and their testators and
intestators.
 
  The NCBC Charter, pursuant to Tennessee law, provides that the directors of
NCBC will not be liable to the corporation or its shareholders for monetary
damages for breach of fiduciary duty as director except for (i) any breach of
the director's duty of loyalty to the corporation or its shareholders, (ii)
acts or omissions not in good faith which involve intentional misconduct or a
knowing violation of the law, or (iii) liability with regard to unlawful
distributions.
 
  The FCB Articles of Incorporation provide that a director of FCB will not be
liable to the corporation or its shareholders for monetary damages, for breach
of any duty as a director, except liability for (i) any wrongful appropriation
of any business opportunity of the corporation, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) the types of liability set forth in the GBCC dealing with illegal
or unauthorized (a) distributions of corporate assets, (b) repurchases of
stock or (c) commencement of business or (iv) any transaction from which the
director derived an improper material tangible personal benefit.

                       DESCRIPTION OF NCBC CAPITAL STOCK
 
  NCBC is authorized by its Charter to issue up to 175,000,000 shares of NCBC
Common Stock, par value $2.00 per share, of which 99,672,702 shares were
issued and outstanding at July 28, 1998, and up to 5,000,000 shares of
Preferred Stock, no par value, of which no shares are issued and outstanding.
 
  The holders of NCBC Common Stock are entitled to one vote per share on all
matters submitted for action by the shareholders. Any corporate action
requiring shareholder approval other than the election of directors may be
authorized by the affirmative vote of a majority of the shares represented at
a meeting at which a quorum is present or represented. Directors are elected
by a plurality of the votes cast in an election. There is no provision for
cumulative voting with respect to the election of directors. The Board of
Directors is divided into three classes with staggered three-year terms. The
affirmative vote of at least two-thirds of the outstanding shares of each
class of capital voting stock is required to amend, alter, change or repeal
Article Seven of the Charter providing for classification of the Board of
Directors, to approve certain business combinations, including mergers and
consolidations involving NCBC, sale of substantially all of the assets of
NCBC, liquidation of NCBC, reclassification of NCBC's securities and
recapitalizations of NCBC involving amendments to the Charter, unless certain
price and procedural requirements are met. Special meetings of shareholders
may be called by the Chairman, President or Vice President, or by a majority
of the members of the Board of Directors, or by holders of not less than one-
tenth of all shares entitled to vote at such meeting upon request delivered to
the Chairman, President or Secretary of NCBC by such shareholders at least 90
days before the proposed date of the meeting.
 
  All shares of NCBC Common Stock are entitled to share equally in such
dividends as the Board of Directors may declare from sources legally available
therefor. Upon liquidation or dissolution of NCBC, whether voluntary or
involuntary, all shares of NCBC Common Stock are entitled to share equally in
the assets available for distribution to shareholders after payment of all
prior obligations of NCBC. The holders of NCBC Common Stock have no preemptive
rights.
 
  The transfer agent for NCBC Common Stock is The Bank of New York.
 
  NCBC is a legal entity separate and distinct from its subsidiaries,
including its subsidiary banks. There are various legal and regulatory
limitations under federal and state law on the extent to which its
subsidiaries, including its bank and bank holding company subsidiaries, can
finance or otherwise supply funds to NCBC.
 
  The principal source of NCBC's cash revenues is dividends from its
subsidiaries. There are certain limitations under federal and Tennessee law on
the payment of dividends by such subsidiaries. The prior approval of the
appropriate federal regulatory body is required if the total of all dividends
declared by any state member bank of the Federal Reserve System or any
national banking association in any calendar year exceeds the bank's net
profits (as defined) for that year combined with its retained net profits for
the preceding two calendar years, less any required transfers to surplus or a
fund for the retirement of any preferred stock. Such regulatory bodies also
have authority to prohibit a state member bank or bank holding company, such
as NCBC, or a national banking association from engaging in what, in the
opinion of such regulatory body, constitutes an unsafe or unsound practice in
conducting its business. The payment of dividends could, depending upon the
financial condition of the subsidiary, be deemed to constitute such an unsafe
or unsound practice.
 
  Retained earnings of NCBC's banking subsidiaries available for payment of
cash dividends under all applicable regulations would have been approximately
$32.293 million as of December 31, 1997. See Note N to the Financial
Statements of NCBC, incorporated by reference in this Proxy
Statement/Prospectus, with respect to certain contractual limits on dividend
payments by NCBC.
 
  NCBC's subsidiaries, subsidiary banks and their respective subsidiaries are
subject to limitations under Section 23A of the Federal Reserve Act with
respect to extensions of credit to, investments in, and certain other
transactions with, NCBC and its other subsidiaries. Furthermore, loans and
extensions of credit are also subject to various collateral requirements.

  Certain provisions of the Charter and Bylaws of NCBC may restrict changes of
control of NCBC. These provisions include the authority to issue preferred
stock with such rights and privileges as the Board of Directors may deem
appropriate from time to time, provisions for the classification of the NCBC
Board of Directors and provisions relating to certain business combinations
with certain shareholders. See "Comparison of Rights of FCB and NCBC
Shareholders--Changes in Control" and "--Boards of Directors."

                                   ARTICLE 2
            MANNER OF CONVERTING SHARES AND OPTIONS; EXCHANGE RATIO
 
  2.1 Conversion; Cancellation and Exchange of Shares; Exchange Ratio. At the
Effective Time, by virtue of the Merger becoming effective and without any
action on the part of NCBC, FCB, or the shareholders of either of the
foregoing, the shares of the constituent corporations shall be converted as
follows:
 
    (a) NCBC Capital Stock. Each share of NCBC Capital Stock issued and
  outstanding immediately prior to the Effective Time shall remain issued and
  outstanding from and after the Effective Time.
 
    (b) FCB Common Stock. Each share of FCB Common Stock issued and
  outstanding at the Effective Time shall cease to represent any interest
  (equity, shareholder or otherwise) in FCB and shall, except for those
  shares (the "Dissenting Shares") held by any FCB Record Holders who shall
  have properly perfected such Holders' dissenters' rights and shall have
  maintained the perfected status of such dissenters' rights through the
  Effective Time ("FCB Dissenting Shareholders"), whose rights shall be
  governed by the provisions of Sections 14-2-1301 through 14-2-1332 of the
  Georgia Code, automatically be converted exclusively into, and constitute
  only the right of each FCB Record Holder to receive in exchange for such
  Holder's shares of FCB Common Stock, the Consideration to which the FCB
  Record Holder is entitled as provided in this Section 2.1(b).
 
                                      I-6
<PAGE>
 
      (i) The Exchange Ratio Calculation. Subject to any adjustments which
    may be required by an event described in Subsection 2.1(b)(iii) below,
    at and as of the Effective Time:
 
        (A) Each one (1) share of FCB Common Stock (other than Dissenting
      Shares) outstanding at and as of the Effective Time shall be
      converted into the right to receive that number of shares of NCBC
      Common Stock equal to the quotient of:
 
                (I) The quotient of (x) the sum of the Net Purchase Price
              (defined below) and the Cost of Unexercised FCB Options (defined
              below), (y) divided by the NCBC "Market Price Per Share"
              (defined below),
 
                                  divided by
 
                (II) The sum of number of shares of FCB Common Stock
              outstanding at and as of the Effective Time and the number of
              options to purchase FCB Common Stock outstanding at and as of
              the Effective Time.
 
        (B) Each share of FCB Common Stock held of record by a FCB
      Dissenting Shareholder shall be converted into the right to receive
      payment from the Surviving Corporation with respect thereto in
      accordance with the provision of the Georgia Code.
 
        (C) "Net Purchase Price" shall be equal to $33,034,041. "Cost of
      Unexercised FCB Options" shall be equal to $1,583,344.
 
        In the event total consolidated stockholders' equity of FCB,
      exclusive of any securities gains or losses in accordance with FAS
      115, is less than $8,330,000 as of the day immediately preceding the
      Effective Time, NCBC reserves the unilateral right to either
      renegotiate the Net Purchase Price or terminate this Agreement.
 
        No share of FCB Common Stock shall be deemed to be outstanding or
      have any rights other than those set forth in this Section 2.1(b)
      after the Effective Time. No fractional shares of NCBC Common Stock
      shall be issued in the Merger and, if after aggregating all of the
      whole and fractional shares of NCBC Common Stock to which a FCB
      Record Holder shall be entitled based upon this Exchange Ratio
      Calculation, there should be a fractional share of NCBC Common Stock
      remaining, such fractional share shall be settled by a cash payment
      therefor pursuant to Article 3 of this Agreement, which cash
      settlement shall be based upon the Current Market Price Per Share
      (as defined below) of one (1) full share of NCBC Common Stock.
 
      (ii) Definition of "Market Price Per Share". The "Market Price Per
    Share" is $21.519, which is the average of the closing price per share
    of NCBC Common Stock on the NASDAQ (as reported by The Wall Street
    Journal) on the five (5) trading day period from April 3, 1998, through
    April 9, 1998 ($43.038), as adjusted for the two-for-one stock split
    with respect to the NCBC Common Stock that occurred on July 1, 1998:

      Therefore, assuming FCB owns 100% of the authorized and outstanding
    common stock of FCB Bank Subsidiary and has consolidated stockholders'
    equity not less than $8,330,000, then:

      (iii) Effect of Stock Splits, Reverse Stock Splits, Stock Dividends
    and Similar Changes in the Capital of FCB. Should FCB effect any stock
    splits, reverse stock splits, stock dividends or similar changes in its
    respective capital accounts subsequent to the date of this Agreement
    but prior to the Effective Time, the Exchange Ratio may, in NCBC's sole
    discretion if such change in the capital accounts constitutes a breach
    of any of FCB's representations, warranties or covenants, be adjusted
    in such a manner as the Board of Directors of NCBC shall deem in good
    faith to be fair and reasonable in order to give effect to such
    changes. Notwithstanding the foregoing, nothing in this subparagraph
    (iii) shall be deemed to be a waiver of the inaccuracy of any
    representation or warranty or breach of any covenant by FCB set forth
    herein.
 
    (c) Shares Held by FCB or NCBC. Each of the shares of FCB Common Stock
  held by any FCB Company or by any NCBC Company, in each case other than (x)
  in a fiduciary capacity, (y) under the FCB Employee Stock Ownership Plan
  with 401(k) features, or (z) as a result of debts previously contracted,
  shall be canceled and retired at the Effective Time and no Consideration
  shall be issued in exchange therefor.
 
    (d) Dissenters' Rights of FCB Shareholders. Any FCB Dissenting
  Shareholder who shall comply strictly with the provisions of Sections 14-2-
  1301, et seq. of the Georgia Code shall be entitled to dissent from the
  Merger and to seek those appraisal remedies afforded by the Georgia Code.
 
  2.2 Conversion of Stock Options.
 
    (a) At the Effective Time, all rights with respect to FCB Common Stock
  pursuant to stock options ("FCB Options") granted by FCB under the FCB
  Stock Plans, which are outstanding at the Effective Time, whether or not
  exercisable, shall be converted into and become rights with respect to NCBC
  Common Stock, and NCBC shall assume each FCB Option, in accordance with the
  terms of the FCB Stock Plan and stock option agreement by which it is
  evidenced. From and after the Effective Time, (i) each FCB Option assumed
  by NCBC may be exercised solely for shares of NCBC Common Stock, (ii) the
  number of shares of NCBC Common Stock subject to such FCB Option shall be
  equal to the number of shares of FCB Common Stock subject to such FCB
  Option immediately prior to the Effective Time multiplied by the Exchange
  Ratio, (iii) the per share exercise price under each such FCB Option shall
  be adjusted by dividing the per share exercise price under each such FCB
  Option by the Exchange Ratio and rounding down to the nearest cent, (iv) in
  order to conform the treatment of the holders of such options in the case
  of termination of employment to the treatment that is accorded holders of
  options granted under the NCBC Option Plan, FCB Options that are assumed by
  NCBC and that are exercisable at the effective date of termination of such
  option holder's employment with an NCBC Company (other than for cause or by
  reason of death, disability or retirement of option holder) shall be
  exercisable by such holder within the period beginning on
 
                                      I-8
<PAGE>
 
  the effective date of termination of employment and ending 90 days
  thereafter, and (v) each FCB Option held by a FCB director assumed by NCBC
  which provides for an exercise date within 90 days after termination of
  such holder's status as a FCB director shall be modified to remove such
  provision and substitute in lieu thereof that such exercise must occur
  within ninety (90) days after termination of such holder's status as a
  director of FCB or First Community Bank & Trust, whichever is later. FCB
  shall take all necessary steps to effectuate the foregoing provisions of
  this Section 2.2.
 
    (b) All restrictions or limitations on transfer with respect to FCB
  Common Stock awarded under the FCB Stock Plans or any other plan, program,
  or arrangement of either FCB Company, to the extent that such restrictions
  or limitations shall not have already lapsed, and except as otherwise
  expressly provided in such plan, program or arrangement, shall remain in
  full force and effect with respect to shares of NCBC Common Stock into
  which such restricted stock is converted pursuant to this Agreement.
 
  2.3 Anti-Dilution Provisions. In the event NCBC changes the number of shares
of NCBC Common Stock issued and outstanding prior to the Effective Time as a
result of a stock split, stock dividend, or recapitalization with respect to
such stock and the record date therefor (in the case of a stock dividend) or
the effective date thereof (in the case of a stock split or similar
recapitalization for which a record date is not established) shall be prior to
the Effective Time, the Exchange Ratio shall be proportionately adjusted.
 
                                   ARTICLE 3
                              EXCHANGE OF SHARES
 
  3.1 Exchange Procedures. Promptly after the Effective Time, NCBC and FCB
shall cause the Exchange Agent to mail to the FCB Record Holders appropriate
transmittal materials (which shall specify that delivery shall be effected,
and risk of loss and title to the certificates theretofore representing shares
of FCB Common Stock shall pass, only upon proper delivery of such certificates
to the Exchange Agent). The Exchange Agent may establish reasonable and
customary rules and procedures in connection with its duties. After the
Effective Time, each FCB Record Holder of FCB Common Stock (other than shares
to be canceled pursuant to Section 2.1(c) 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 2.1(b) of this Agreement, together with all undelivered dividends
or distributions in respect of such shares (without interest thereon) pursuant
to Section 3.2 of this Agreement. To the extent required by Section 2.1(b) of
this Agreement, each FCB Record Holder also shall receive, upon surrender of
the certificate or certificates representing his or her shares of FCB Common
Stock outstanding immediately prior to the Effective Time, cash in lieu of any
fractional share of NCBC Common Stock to which such holder may be otherwise
entitled (without interest). NCBC shall not be obligated to deliver the
Consideration to which any FCB Record Holder is entitled as a result of the
Merger until such FCB Record Holder surrenders such holder's certificate or
certificates representing the shares of FCB Common Stock for exchange as
provided in this Section 3.1. The certificate or certificates of FCB Common
Stock so surrendered shall be duly endorsed as the Exchange Agent may
reasonably require. Any other provision of this Agreement notwithstanding,
neither NCBC nor the Exchange Agent shall be liable to a FCB Record Holder for
any amounts paid or properly delivered in good faith to a public official
pursuant to any applicable abandoned property Law. Adoption of this Agreement
by the shareholders of FCB shall constitute ratification of the appointment of
the Exchange Agent.
 
  3.2 Rights of Former FCB Record Holders. At the Effective Time, the stock
transfer books of FCB shall be closed as to holders of FCB Common Stock
outstanding immediately prior to the Effective Time, and no transfer of FCB
Common Stock by any FCB Record Holder shall thereafter be made or recognized.
Until surrendered for exchange in accordance with the provisions of Section
3.1 of this Agreement, each certificate theretofore representing shares of FCB
Common Stock (other than shares to be cancelled pursuant to Section 2.1(c) of
this Agreement) shall from and after the Effective Time represent for all
purposes only the right to receive the Consideration provided in Section
2.1(b) of this Agreement in exchange therefor, subject, however,
 
                                      I-9

                     REPRESENTATIONS AND WARRANTIES OF FCB
 
  Except as disclosed in the FCB Disclosure Memorandum, FCB hereby represents
and warrants to NCBC as follows:
 
  4.1 Organization, Standing and Power. FCB is a corporation duly organized,
validly existing, and in good standing under the laws of the State of Georgia
and has the corporate power and authority to carry on its business as now
conducted and to own, lease and operate its Assets. FCB 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 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 FCB.
 
  4.2 Authority; No Breach of Agreement.
 
    (a) FCB has the corporate power and authority necessary to execute,
  deliver and perform its obligations under this Agreement and the Plan of
  Merger and to consummate the transactions contemplated hereby and thereby.
  The execution, delivery and performance of this Agreement and the Plan of
  Merger, as appropriate, and the consummation of the transactions
  contemplated herein and therein, including the Merger, have been duly and
  validly authorized by all necessary corporate action in respect thereof on
  the part of FCB, subject to the approval of this Agreement and the Plan of
  Merger by the holders of a majority (or such greater percentage as may be
  required by the Articles of Incorporation of FCB or other applicable law)
  of the outstanding shares of FCB Common Stock, which is the only
  shareholder vote required for approval of this Agreement and the Plan of
  Merger and consummation of the Merger by FCB. Subject to the receipt of
  such requisite shareholder approval, this Agreement and the Plan of Merger
  represent legal, valid and binding obligations of FCB, enforceable against
  FCB in accordance with their respective terms (except in all cases as such
  enforceability may be limited by applicable bankruptcy, insolvency,
  reorganization, receivership, conservatorship, 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 or the Plan of
  Merger, as appropriate, by FCB, nor the consummation by FCB of the
  transactions contemplated hereby or thereby, nor compliance by FCB with any
  of the provisions hereof or thereof will (i) conflict with or result in a
  breach of any provision of FCB's Articles of Incorporation or Bylaws, or
  (ii) except as disclosed in Section 4.2(b) of the FCB Disclosure
  Memorandum, constitute or result in a Default under, or require any Consent
  (other than shareholder approval) pursuant to, or result in the creation of
  any Lien on any material Asset of any FCB Company under, any Contract or
  Permit of any FCB Company, or (iii) subject to receipt of the requisite
 
                                     I-10

  Order applicable to either FCB Company or any of their respective Material
  Assets.

  Securities Laws, applicable state corporate Laws, and other than Consents
  required from Regulatory Authorities, and other than notices to or filings
  with the Internal Revenue Service or the Pension Benefit Guaranty
  Corporation with respect to any FCB Employee Plans or under the HSR Act,
  and other than 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 FCB, no notice to, filing with, or Consent of,
  any public body or authority is necessary for the consummation by FCB of
  the Merger and the other transactions contemplated in this Agreement and
  the Plan of Merger.
 
    (d) Neither FCB Company is a party to, or subject to, or bound by, any
  agreement or judgment, order, letter of understanding, writ, prohibition,
  injunction or decree of any court or other governmental body of competent
  jurisdiction, or any law which would prevent the execution and delivery of
  this Agreement and the Plan of Merger by FCB, or the consummation of the
  transactions contemplated hereby and thereby, and no action or proceeding
  is pending against either FCB Company in which the validity of this
  Agreement, the transactions contemplated hereby or any action which has
  been taken by any of such Parties in connection herewith or in connection
  with the transaction contemplated hereby is at issue.

sheets of FCB included in the FCB Regulatory Financial Statements as of dates
subsequent to the execution of this Agreement and as of the Closing Date will

guidelines) to provide for all known and reasonably anticipated losses
relating to or inherent in the loan and lease portfolios (including accrued
interest receivables and ORE reserves) of the FCB Companies and other
extensions of credit (including letters of credit and commitments to make
loans or extend credit) by the FCB Companies as of the dates thereof. Except
as described in Section 4.9 of the FCB Disclosure Memorandum (by loan type,
loan number, classification and outstanding balance), neither FCB Company has
any Loan or other extension of credit which has been (or should have been in
management's reasonable opinion) classified as "Other Assets Especially

<PAGE>
 
Disclosure Memorandum also lists all Loans or extensions of credit which are

all of their respective Assets. All tangible Assets used in the businesses of
the FCB Companies are in good condition, reasonable wear and tear excepted,
and are usable in the ordinary course of business consistent with FCB's past
practices. All Assets which are material to FCB's business on a consolidated
basis, held under leases or subleases by either of the FCB Companies, 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. To the best of management's
Knowledge, the FCB Companies currently maintain insurance similar in amounts,
scope, and coverage to that maintained by other peer banking organizations.
Neither of the FCB Companies has received notice from any insurance carrier
that (i) such insurance would be canceled or that coverage thereunder will be
reduced or eliminated, or (ii) premium costs with respect to such policies of
insurance will be substantially increased. Except as set forth in Section 4.10
of the FCB Disclosure Memorandum, there are presently no claims pending under
any such policies of insurance and no notices have been given by either FCB
Company under such policies.
 
  4.11 Intellectual Property. All of the Intellectual Property rights of the
FCB Companies are in full force and effect and constitute legal, valid and
binding obligations of the respective parties thereto, and there have not
been, and, to the Knowledge of FCB, there currently are not, any defaults
thereunder by either FCB Company. An FCB Company owns or is the valid licensee
of all such Intellectual Property rights free and clear of all liens or claims
of infringement. Neither of the FCB Companies or, to the Knowledge of FCB,
their respective predecessors, has misused the Intellectual Property rights of
others and none of the Intellectual Property rights as used in the business
conducted by either such FCB Company infringes upon or otherwise violates the
rights of any Person, nor has any Person asserted a claim of such
infringement. Except as disclosed in Section 4.11 of the FCB Disclosure
Memorandum, neither FCB Company is obligated to pay any royalties to any
Person with respect to any such Intellectual Property. Each FCB Company owns
or has the valid right to use all of the Intellectual Property rights which it
is presently using, or in connection with performance of any material Contract
to which it is a party. No officer, director, or employee of either FCB
Company is party to any Contract which requires such officer, director or
employee to assign any interest in any Intellectual Property or keep
confidential any trade secrets, proprietary data, customer information, or
other business information except as disclosed in Section 4.11 of the FCB
Disclosure Memorandum, which restricts or prohibits such officer, director or
employee from engaging in activities competitive with any person, including
either FCB Company.
 
  4.12 Environmental Matters. Except as set forth in Section 4.12 of the FCB
Disclosure Memorandum:
 
    (a) To the Knowledge of FCB, each FCB Company, its Participation
  Facilities, and its Operating Properties are, and have been, in 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 FCB.
 
    (b) There is no litigation pending or, to the Knowledge of FCB,
  threatened before any court, governmental agency or authority or other
  forum in which either FCB Company or any of its Operating Properties or
  Participation Facilities (or FCB in respect of such Operating Property or
  Participation Facility) has 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, whether or not occurring
  at, on, under, adjacent to, or
 
                                     I-15
<PAGE>
 
  affecting (or potentially affecting) a site owned, leased, or operated by
  either FCB Company or any of its Operating Properties or 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 FCB, nor, to the knowledge of FCB, is there any
  reasonable basis for any litigation of a type described in this sentence.
 
    (c) To the Knowledge of FCB, during the period of (i) either FCB
  Company's ownership or operation of any of their respective current
  properties, (ii) either FCB Company's participation in the management of
  any Participation Facility, or (iii) either FCB Company's holding of a
  security interest in an Operating Property, there have been no releases of
  hazardous material in, on, under, adjacent to, or affecting (or potentially
  affecting) such properties, except such as are not reasonably likely to
  have, individually or in the aggregate, a Material Adverse Effect on FCB.
  To the Knowledge of FCB, prior to the period of (i) either FCB Company's
  ownership or operation of any of their respective current properties, (ii)
  either FCB Company's participation in the management of any Participation
  Facility, or (iii) either FCB Company's holding of a security interest in
  an Operating Property, to the Knowledge of FCB, there were no releases of
  Hazardous Material in, on, under, or affecting such property, Participation
  Facility or Operating Property, except such as are not reasonably likely to
  have, individually or in the aggregate, a Material Adverse Effect on FCB.
 
  4.13 Compliance with Laws. FCB is duly registered as a bank holding company
under the BHC Act. Each FCB Company has in effect all (i) Permits required by
any applicable state or federal bank regulatory authority ("Regulatory
Permits") and (ii) all other Permits necessary for it to own, lease or operate
its material Assets and to carry on its 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 FCB, and there
has occurred (i) no default under any such Regulatory Permit and (ii) no
Default under any such other Permit other than Defaults which are not
reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on FCB. Except as set forth in Section 4.13 of the FCB
Disclosure Memorandum, neither of the FCB Companies:
 
    (a) Is in violation of any (i) Laws, Orders or Permits applicable to
  banks or bank holding companies; or (ii) any other Laws, Orders or Permits

  Permits, or (iii) requiring either FCB Company to enter into or consent to
  the issuance of a cease and desist order, formal agreement, directive, 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.
 
  4.14 Labor Relations. Neither FCB Company is the subject of any Litigation
asserting that it or the other FCB Company has committed an unfair labor
practice (within the meaning of the National Labor Relations Act or comparable
state Law) or seeking to compel it or any other FCB Company to bargain with
any labor organization as to wages or conditions of employment, nor is there
any strike or other labor dispute involving either FCB Company, pending or
threatened, or to the Knowledge of FCB, is there any activity involving FCB

  4.15 Employee Benefit Plans.
 
    (a) FCB has disclosed in Section 4.15(a) of the FCB Disclosure
  Memorandum, and has delivered or made available to NCBC prior to the date
  of this Agreement copies in each case of, all pension, retirement, profit
  sharing, deferred compensation, stock option, employee stock ownership,
  severance pay, vacation,
 
                                     I-16
<PAGE>
 
  bonus or other incentive plan, all other written employee programs,
  arrangement 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 "employee benefit plans" as that term is
  defined in Section 3(3) of ERISA, currently adopted, maintained by,
  sponsored in whole or in part by, or contributed to by any FCB Company or
  ERISA Affiliate thereof for the benefit of employees, retirees, dependents,
  spouses, directors, independent contractors, or other beneficiaries and
  under which employees, retirees, dependents, spouses, directors,
  independent contractors, or other beneficiaries are eligible to participate
  (collectively the "FCB Benefit Plans"). Any of the FCB 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 "FCB ERISA Plan." Each FCB ERISA
  Plan which is also a "defined benefit plan" (as defined in IRC Section
  414(j) is referred to herein as a "FCB Pension Plan." No FCB Pension Plan
  is or has been a multi-employer plan within the meaning of Section 3(37) of
  ERISA.
 
    (b) All FCB Benefit Plans are in compliance with the applicable terms of
  ERISA, the IRC 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 FCB. Each FCB ERISA Plan which is intended to be
  qualified under IRC Section 401(a) has received a favorable determination
  letter from the Internal Revenue Service, and FCB is not aware of any
  circumstances likely to result in revocation of any such favorable
  determination letter. No FCB Company has engaged in a transaction with
  respect to any FCB Benefit Plan that, assuming the taxable period of such
  plan expired as of the date hereof, would subject any FCB Company to a tax
  imposed by either IRC Section 4975 or Section 502(i) of ERISA.
 
    (c) No FCB Pension Plan (other than the EPP (as defined in Section
  7.13(c)) has any "unfunded current liability," as that term is defined in
  Section 302(d)(8)(A) of ERISA, 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
  evaluation, there has been (i) no material change in the financial position
  of any FCB Pension Plan, (ii) no change in the actuarial assumptions with
  respect to any FCB Pension Plan, and (iii) no increase in benefits under
  any FCB 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 FCB or materially adversely affect
  the funding status of any such plan. Neither any FCB Pension Plan nor any
  "single-employer plan," within the meaning of Section 4001(a)(15) of ERISA,
  currently or formerly maintained by any FCB Company, or the single-employer
  plan of any entity which is considered one employer with FCB under Section
  4001 of ERISA or IRC Section 414 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. Neither FCB Company has provided, or is required to provide,
  security to a FCB Pension Plan or to any single-employer plan of an ERISA
  Affiliate pursuant to IRC Section 401(a)(29).
 
    (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 any FCB Company with respect to any ongoing, frozen or
  terminated single-employer plan or the single-employer plan of any ERISA
  Affiliate. Neither FCB Company has incurred any withdrawal liability with
  respect to a multi-employer plan under Subtitle B of Title IV of ERISA
  (regardless of whether based on contributions of an ERISA Affiliate). 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 FCB Pension Plan or by any ERISA Affiliate
  within the 12-month period ending on the date hereof.
 
    (e) Except as disclosed in Section 4.15(e) of the FCB Disclosure
  Memorandum, neither FCB Company has any liability for retiree health and
  life benefits under any of the FCB Benefit Plans to former employees and
  there are no restrictions on the rights of such FCB Company to amend or
  terminate any such retiree health or benefit plan without incurring
  liability thereunder.

<PAGE>
 
    (f) Except as disclosed in Section 4.15(f) of the FCB Disclosure
  Memorandum, neither the execution and delivery of this Agreement nor the
  consummation of the transactions contemplated hereby will (i) result in any
  payment (including severance, unemployment compensation, golden parachute,
  or otherwise) becoming due to any director or any employee of any FCB
  Company from either FCB Company under any FCB Benefit Plan or otherwise,
  (ii) increase any benefits otherwise payable under any FCB 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 entitlements under any executive compensation,
  supplemental retirement or employment agreement) of employees and former
  employees of either FCB Company and their respective beneficiaries, other
  than entitlements accrued pursuant to funded retirement plans subject to
  the provisions of IRC Section 412 or Section 302 of ERISA, have been fully
  reflected on the FCB Financial Statements to the extent required by and in
  accordance with GAAP.
 
    (h) Prior to consummation of the Merger, FCB's KSOP with 401(k) feature
  will be terminated.
 
  4.16 Material Contracts. Except as disclosed in Section 4.16 of the FCB
Disclosure Memorandum and in Section 10.3 of this Agreement, neither of the
FCB Companies, nor any of their respective assets, businesses or operations,
is a party to or, or is bound or affected by, or receives benefits under (i)
any employment, severance, termination, consulting or retirement contract or
contracts providing for aggregate payments (x) to any person in any calendar
year in excess of $10,000, or (y) to any one or more Persons in the aggregate
in excess of $50,000, (ii) any contract relating to the borrowing of money by
either FCB Company or the guarantee by either FCB Company of any such
obligation (other than contracts evidencing deposit liabilities, purchases of
federal funds, fully secured repurchase agreements and Federal Home Loan Bank
advances of depository institution subsidiaries, trade payables, and contracts
relating to borrowings or guarantees made in the ordinary course of business),
(iii) any contracts which prohibit or restrict either FCB Company from
engaging in any business activities in any geographic area, line of business
or otherwise in competition with any other person, (iv) any contracts between
FCB Companies, (v) any exchange-traded or over-the-counter swap, forward,
future, option, cap, floor or collar financial contract, or any other interest
rate or foreign currency protection contract (not disclosed in the FCB
Financial Statements delivered prior to the date of this Agreement) which is a
financial derivative contract (including various combinations thereof), and
(vi) any other material contract or amendment thereto that would be required
to be filed as an exhibit to a FCB SEC Report (whether or not FCB is subject
to the filing requirements of the SEC) filed (or which would have been filed
if FCB were subject to the SEC reporting requirements) by FCB with the SEC
prior to the date of this Agreement (together with all contracts referred to
in Sections 4.10 and 4.15(a) of this Agreement (the "FCB Contracts")). With
respect to each FCB Contract: (i) to the Knowledge of FCB, the Contract is in
full force and effect; (ii) neither FCB Company is in Default thereunder,
(iii) neither FCB Company has repudiated or waived any material provision of
any such contract; and (iv) no other party to any such contract is, to the
Knowledge of FCB, in Default in any respect or has repudiated or waived any
material provision thereunder. Except as set forth in Section 4.16 of the FCB
Disclosure Memorandum, all of the indebtedness of either FCB Company for money
borrowed is prepayable at any time by such FCB Company without penalty or
premium.
 
  4.17 Legal Proceedings. There is no Litigation pending or, to the Knowledge
of FCB, threatened (or unasserted but considered probable of assertion and
which if asserted would have at least a reasonable probability of an
unfavorable outcome) against either FCB Company, or against any Asset,
interest, or right of any of them that is reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on FCB, nor are
there any orders of any Regulatory Authorities, other governmental
authorities, or arbitrators outstanding against either FCB Company. Section
4.17 of the FCB Disclosure Memorandum includes a report of all material
litigation as of the date of this Agreement to which either FCB Company is a
party and which names a FCB Company as a defendant or cross-defendant.
 
  4.18 Reports. Since January 1, 1995, each FCB Company has timely filed all

SEC, if applicable, including Forms 10-K, Forms 10-Q, Forms 8-K and proxy
statements, (ii) all other Regulatory Authorities, and (iii) any applicable
state securities or banking authorities (except failures to file which are not
reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on FCB). 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 its
respective date, 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.
 
  4.19 Statements True and Correct. No statement, certificate, instrument or

therein, in light of the circumstances under which they were made, not
misleading. None of the information supplied or to be supplied by either FCB
Company or any Affiliate thereof for inclusion in the Registration Statement

of FCB, 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 any material fact, or

material respects with the provisions of applicable Law.
 
  4.20 Accounting, Tax and Regulatory Matters. Neither FCB Company or any
Affiliate thereof has taken any action or has any Knowledge of any fact or
circumstance relating to FCB that is reasonably likely to (i) prevent the
transactions contemplated hereby, including the Merger, from qualifying for

meaning of Section 368(a) of the IRC, or (ii) materially impede or delay
receipt of any Consents of Regulatory Authorities referred to in Section

"Takeover Laws"), including Sections 14-2-1110, et seq. of the Georgia Code.
 
  4.22 Articles of Incorporation Provisions. Each FCB Company has taken all
action so that the entering into of this Agreement and the Plan of Merger and
the consummation of the Merger and the other transactions contemplated by this
Agreement and the Plan of Merger do 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 either FCB Company (other than voting, dissenters'
appraisal or other similar rights) or restrict or impair the ability of NCBC
or any of its Subsidiaries to vote, or otherwise to exercise the rights of a

  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

  contemplated hereby or any action which has been taken by any of such
  Parties in connection herewith or in connection with the transaction
  contemplated hereby is at issue.

transactions contemplated hereby, including the Merger, from qualifying for
pooling-of-interests accounting treatment or as a reorganization within the
meaning of Section 368(a) of the IRC or (b) adversely affect in any material
respect the ability of any Party to perform its covenants and agreements under
this Agreement.

  6.3 Covenants of NCBC. From the date of this Agreement until the earlier of
the Effective Time or the termination of this Agreement, NCBC covenants and
agrees that it shall (i) continue to conduct its business and the business of
its Subsidiaries in a manner designed in its reasonable judgment to enhance
the long-term value of the NCBC Common Stock and the business prospects of the
NCBC Companies, and (ii) take no action which would (a) materially adversely
affect the ability of any Party to obtain any Consents required for the
transactions contemplated hereby without imposition of a condition or
restriction of the type referred to in the last sentence of Section 8.1(b) of
this Agreement or prevent the transactions contemplated hereby, including the
Merger, from qualifying for pooling-of-interests accounting treatment or as a
reorganization within the meaning of IRC Section 368(a), or (b) materially
adversely affect the ability of any Party to perform its covenants and
agreements under this agreement, provided, that the foregoing shall not
prevent any NCBC Company from acquiring any other assets or businesses or from
discontinuing or disposing of any of its assets or business if such action is,
in the judgment of NCBC, desirable in the conduct of the business of NCBC and
its Subsidiaries and would not, in the judgment of NCBC, likely delay the
Effective time to a date subsequent to the date set forth in Section 9.1(e) of
this Agreement.
 
  6.4 Adverse Changes in Condition. Each Party agrees to give written notice
promptly to the other Party upon becoming aware of the occurrence or impending
occurrence of any event or circumstance relating to it or any of its
Subsidiaries which (i) is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on it or (ii) would cause or constitute a
material breach of any of its representations, warranties or covenants
contained herein, and to use its reasonable efforts to prevent or promptly to
remedy the same.
 
  6.5 Reports. Each Party and its Subsidiaries shall file all reports required
to be filed by it with Regulatory Authorities between the date of this
Agreement and the Effective Time and shall deliver to the other Party copies
of all such reports promptly after the same are filed. If financial statements
are contained in any such reports filed with any Regulatory Authority pursuant
to the Securities Laws, such financial statements will fairly present the
consolidated financial position of the entity filing such statements as of the
dates indicated and the consolidated results of operations, changes in
shareholders' equity, and cash flows for the periods then ended in accordance
with GAAP or regulatory accounting (subject in the case of interim financial
statements to normal recurring year-end adjustments that are not material). As
of their respective dates, such reports filed with any Regulatory Authorities
pursuant to the Securities Laws will comply in all material respects with the
Securities Laws and will not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under
which they were made, not misleading. Any financial statements contained in
any other reports to another Regulatory Authority shall be prepared in
accordance with laws applicable to such reports.

                             ADDITIONAL AGREEMENTS
 
  7.1 Registration Statement; Proxy Statement; Shareholder Approvals. NCBC
shall file the Registration Statement with the SEC, and shall use its
reasonable effort to cause the Registration Statement to become effective
under the 1933 Act and take any action required to be taken under the
applicable state Blue Sky or Securities Laws in connection with the issuance
of the shares of NCBC Common Stock upon consummation of the Merger. FCB shall
furnish all information concerning it and the holders of its capital stock as
NCBC may reasonably request in connection with such action. FCB 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 the Plan of Merger and such other
related matters as its deems appropriate. In connection with the shareholders'
meeting, (i) NCBC and FCB shall prepare a Proxy Statement (which shall be
included in the Registration Statement with the SEC) and mail such Proxy
Statement to the shareholders of FCB, (ii) the Parties shall furnish to each
other all information concerning them that they may reasonably request in
connection with such Proxy Statement, (iii) the Board of Directors of FCB
shall recommend (subject to compliance with their fiduciary duties as advised
by counsel) to their shareholders the approval of the matters submitted for
approval, and (iv) the Board of Directors and officers of FCB shall (subject
to compliance with their fiduciary duties as advised by counsel) use their
reasonable efforts to obtain such shareholders' approvals.
 
  7.2 Exchange Listing. NCBC shall use its reasonable efforts to list, prior
to the Effective Time, on the NASDAQ, subject to official notice of issuance,
the shares of NCBC Common Stock to be issued to the holders of FCB Common
Stock or FCB Stock Options pursuant to the Merger, and NCBC shall give all
notices and make all filings with the NASDAQ required in connection with the
transactions contemplated herein.
 
  7.3 Applications. NCBC shall prepare and file, and FCB shall cooperate in
the preparation and, where applicable, filing of applications with all
Regulatory Authorities having jurisdiction over the transactions contemplated
by this Agreement seeking the requisite Consents necessary to consummate the
transactions contemplated by this Agreement. At least two business days prior
to filing, NCBC shall provide FCB and its counsel with copies of such
applications to review and approve with respect to information relating to
FCB. The Parties shall deliver to each other copies of all filings,
correspondence and orders to and from, all Regulatory Authorities in
connection with the transactions contemplated hereby as soon as practicable
upon their becoming available.
 
  7.4 NCBC Filings with State Offices. Upon the terms and subject to the
conditions of this Agreement, NCBC and FCB shall execute and file the Articles
of Merger with the Secretary of State of the states of Georgia and Tennessee
in connection with the Closing.
 
  7.5 Agreement as to Efforts to Consummate. Subject to the terms and
conditions of this Agreement, each Party agrees to use, and to cause its
Subsidiaries to use, its reasonable efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws to consummate and make effective, as soon as
practicable after the date of this Agreement, the transactions contemplated by
this Agreement, including 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 8 of this Agreement; provided, however, that nothing herein shall
preclude either Party from exercising its rights under this Agreement. Each
Party shall use, and shall cause each of its Subsidiaries to use, its
reasonable efforts to obtain all Consents necessary or desirable for the
consummation of the transactions contemplated by this Agreement; provided,
however, that nothing in this Section 7.5 shall be construed to obligate NCBC
to take any action to meet any condition required for it to obtain any Consent
if NCBC shall, in its sole discretion, deem such condition to be unreasonable
or to constitute a significant impediment upon NCBC's ability to carry on its
business or acquisition programs or to require NCBC to increase its capital
ratios to amounts in excess of the Federal Reserve's minimum capital ratio
guidelines which may from time to time be in effect.

  7.6 Investigation and Confidentiality.
 
    (a) Prior to the Effective Time, each Party shall keep the other Party
  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 be made such investigation of the business and properties of it
  and its Subsidiaries and of their respective financial and legal conditions
  as the other Party reasonably requests, provided that such investigation
  shall be reasonably related to the transactions 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.
 
    (b) Each Party shall, and shall cause its advisers and agents to,
  maintain the confidentiality of all confidential information furnished to
  it by the other Party concerning its and its Subsidiaries' businesses,
  operations and financial positions and shall not use such information for
  any purpose except in furtherance of the transactions contemplated by this
  Agreement. If this Agreement is terminated prior to the Effective Time,
  each Party shall promptly return or certify the destruction of all
  documents and copies thereof, and all work papers containing confidential
  information received from the other Party.
 
    (c) FCB shall use its reasonable efforts to exercise its rights under
  confidentiality agreements entered into with persons which are considering
  an Acquisition Proposal with FCB to preserve the confidentiality of the
  information relating to FCB provided to such persons and their Affiliates
  and representatives.
 
    (d) Each Party shall 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 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.
 
  7.7 Press Release. Prior to the Effective Time, FCB and NCBC 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, that nothing in this Section 7.7
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.
 
  7.8 Certain Actions.
 
    (a) Except with respect to this Agreement and the Plan of Merger and the
  transactions contemplated hereby and thereby, after the date of this
  Agreement, neither FCB Company nor any Affiliate thereof nor any
  representatives thereof retained by either FCB Company shall directly or
  indirectly solicit or knowingly encourage any Acquisition Proposal by any
  Person. Except to the extent necessary to comply with the fiduciary duties
  of FCB Board of Directors as advised by counsel, neither FCB Company and no
  Affiliate or representative of FCB or either FCB Company shall furnish any
  non-public information that it is not legally obligated to furnish,
  negotiate with respect to, or enter into, or agree to enter into any
  contract with respect to any Acquisition Proposal, but FCB may communicate
  information about such an Acquisition Proposal to its shareholders if and
  to the extent that it is required to do so in order to comply with its
  legal obligations as advised by counsel. FCB shall promptly notify NCBC
  orally and in writing in the event that it receives any inquiry or proposal
  relating to any such transaction. FCB 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.
 
    (b) As a condition of and as an inducement to NCBC's entering this
  Agreement, FCB covenants, acknowledges and agrees that it shall be a
  specific, absolute and unconditionally binding condition precedent to FCB's
  entering into a letter of intent, agreement in principle, or definitive
  agreement (whether or not considered binding, nonbinding, conditional or
  unconditional) with any third party with respect to an Acquisition
  Proposal, or supporting or indicating an intent to support an Acquisition
  Proposal, other than
 
                                     I-27
<PAGE>
 
  this Agreement and the transactions contemplated in this Agreement
  regardless of whether FCB has otherwise complied with the provisions of
  Section 7.8(a) hereof, that FCB or such third party which is a party of the
  Acquisition Proposal shall have paid NCBC the sum of Five Hundred Thousand
  Dollars ($500,000.00), which sum represents the (i) direct costs and
  expenses (including, but not limited to, fees and expenses incurred by
  NCBC's financial or other consultants, printing costs, investment bankers,
  accountants, and counsel) incurred by or on behalf of NCBC in negotiating
  and undertaking to carry out the transactions contemplated by this
  Agreement; and (ii) indirect costs and expenses of NCBC in connection with
  the transactions contemplated by this Agreement, including NCBC's
  management time devoted to negotiation and preparation for the transactions
  contemplated by this Agreement; and (iii) NCBC's loss as a result of the
  transactions contemplated by this Agreement not being consummated.
  Accordingly, FCB hereby stipulates and covenants that prior to FCB entering
  into a letter of intent, agreement in principle, or definitive agreement
  (whether binding, nonbinding, conditional or unconditional) with any third
  party with respect to an Acquisition Proposal or supporting or indicating
  an intent to support an Acquisition Proposal, either FCB or such third
  party shall have paid to NCBC the amount set forth above in immediately
  available funds to satisfy the specific absolute, and unconditionally
  binding condition precedent imposed by this Section 7.8. Notwithstanding
  anything to the contrary in this Section 7.8(b) in the event such
  Acquisition Proposal should be the result of a hostile takeover of FCB, any
  sums due NCBC hereunder shall be paid only at the closing of the
  transactions set forth in such Acquisition Proposal. NCBC acknowledges that
  under no circumstances shall any officer or director of FCB (unless such
  officer or director shall have an interest in a potential acquiring party
  in any Acquisition Proposal) be held personally liable to NCBC for any
  amount of the foregoing payment. On the payment of such amount to NCBC,
  NCBC shall have no cause of action or claim (either in law or in equity)
  whatsoever against FCB, or any officer or director of FCB, with respect to
  or in connection with such Acquisition Proposal, this Agreement or the Plan
  of Merger, and upon payment of such amount this Agreement shall terminate.
 
    (c) The requirements, conditions and obligations imposed by this Section
  7.8 shall continue in full force and effect from the date of this Agreement
  until December 31, 1998, unless and until the earlier of any of the events
  specified in the second paragraph of this paragraph (c) shall occur, in
  which event FCB shall not be obligated to pay the amount required by this
  Section 7.8 as a condition precedent to such transaction.
 
    This Agreement shall have been terminated (i) mutually by the Parties
  pursuant to Section 9.1(a) of this Agreement; (ii) by FCB pursuant to
  Section 9.1(b) of this Agreement; (iii) Reserved; (iv) by either Party
  pursuant to Section 9.1(d)(i) of this Agreement; (v) by FCB pursuant to
  Section 9.1(f) of this Agreement, other than due to the failure to satisfy
  Section 8.1(a); or (vi) by FCB pursuant to Section 9.1(c) of this
  Agreement, but in such event only on the basis of (a) material inaccuracy
  (without waiver thereof) of representations and warranties of NCBC as
  contemplated by the provisions of Section 8.3(a) of this Agreement; (b)
  noncompliance by NCBC with its obligations as required by the provisions of
  Section 8.3(b) of this Agreement; or (c) the failure of NCBC to deliver all
  certificates as required by the provisions of Section 8.3(c) of this
  Agreement, or (d) the failure of NCBC to satisfy the conditions set forth
  in Section 8.3(d) of this Agreement.
 
  7.9 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 IRC
Section 368(a) for federal income tax purposes.
 
  7.10 State Takeover Laws. Each FCB Company shall take all reasonable steps
to exempt the transactions contemplated by this Agreement from, or if
necessary challenge the validity or applicability, of any applicable Takeover
Law.
 
  7.11 Articles of Incorporation Provisions. Each FCB Company shall take all
necessary action to ensure that the entering into of this Agreement and the
Plan of Merger and the consummation of the Merger and the
 
                                     I-28
<PAGE>
 
other transactions contemplated hereby and thereby do 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 either FCB Company (other than
voting, dissenters' appraisal and other similar rights) or restrict or impair
the ability of NCBC or any of its Subsidiaries to vote, or to exercise the
rights of a shareholder with respect to, shares of any FCB Company that may be
directly or indirectly acquired or controlled by it.
 
  7.12 Agreement of Affiliates. FCB has disclosed in Section 7.12 of the FCB
Disclosure Memorandum all persons whom it reasonably believes is an
"affiliate" of FCB for purposes of Rule 145 under the 1933 Act. FCB shall use
its reasonable efforts to cause each such Person to deliver to NCBC not later
than thirty (30) days prior to the Effective Time, a written agreement,
substantially in the form of Exhibit 3, providing that such Person will not
sell, pledge, transfer, or otherwise dispose of the shares of FCB 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 NCBC Common Stock to be received by such Person upon consummation of
the Merger except in compliance with applicable provisions of the 1933 Act and
the rules and regulations thereunder and until such time as financial results
covering at least thirty (30) days of combined operations of NCBC and FCB 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 NCBC Common Stock issued to such
affiliates of FCB in exchange for shares of FCB Common Stock shall not be
transferable until such time as financial results covering at least thirty
(30) days of combined operations of NCBC and FCB have been published within
the meaning of Section 201.01 of the SEC's Codification of Financial Reporting
Policies, regardless of whether each such affiliate has provided the written
agreement referred to in this Section 7.12 (and NCBC shall be entitled to
place restrictive legends upon certificates for shares of NCBC Common Stock
issued to affiliates of FCB pursuant to this Agreement and to enforce the
provisions of this Section 7.12). NCBC shall not be required to maintain the
effectiveness of the Registration Statement under the 1933 Act for the
purposes of resale of NCBC Common Stock by such affiliates.
 
  7.13 Employee Benefits and Contracts.
 
    (a) Following the Effective Time, NCBC shall provide to officers and
  employees of the FCB Companies employee benefits under employee benefit and
  welfare plans, on terms and conditions which when taken as a whole are
  substantially similar to those currently provided by the NCBC Companies to
  their similarly situated officers and employees. To the extent permitted by
  FCB's KSOP with 401(k) feature and applicable law, as soon as reasonably
  practical after consummation of the Merger, distributions will be made
  under, and in accordance with, FCB's KSOP with 401(k) feature previously
  terminated pursuant to Section 4.15(h) of this Agreement will be terminated
  and distributions made in accordance therewith. For purposes of
  participation, vesting and other benefit accrual, under any such NCBC
  employee benefit plans, the service of the employees of the FCB Companies
  prior to the Effective Time shall be treated as service with an NCBC
  Company participating in such employee benefit plan. Nothing herein shall
  be deemed to have reduced, contracted, enlarged, undertaken, authorized,
  approved or otherwise to have affected whatever contractual rights the
  officers and employees of FCB may have under existing documentation other
  than as expressly stated herein, and nothing herein shall be deemed to be
  an employment contract, agreement or understanding, or offer of employment
  by NCBC or any of its direct or indirect Subsidiaries after the Effective
  Time. With respect to calendar year 1998, NCBC hereby agrees to (i) honor
  FCB's existing policy of paying hourly non-exempt personnel for accrued but
  unused sick days, and (ii) pay a one-time annual year-end bonus to
  employees and officers between Thanksgiving and Christmas, 1998, consistent
  with FCB's practice in prior years. FCB hereby represents and covenants
  that it has accrued and will continue to accrue pursuant to GAAP amounts
  sufficient to enable it to make the foregoing payments. Following Closing,
  NCBC agrees to allow the current directors of FCB to participate in its
  health insurance plans generally available to employees of NCBC, subject to
  eligibility and any other requirements of such plans.
 
    (b) FCB shall use its best efforts to obtain prior to the Closing the
  consent of each participant in the Director's Indexed Fee Continuation
  Program described in Section 4.15(a) of the FCB Disclosure Memorandum,
  including the Endorsement Split Dollar Plan (the "Benmark Plan") to the
  termination of
 
                                     I-29
<PAGE>
 
  the Benmark Plan effective as of the Effective Time. Prior to the Closing,
  FCB shall provide to NCBC a schedule setting forth the amount of
  contributions made to the Benmark Plan by the participants from their own
  funds. Promptly following the Effective Time, NCBC shall pay to each such
  participant an amount equal to the contribution made by such participant,
  together with interest thereon from the date(s) of the contribution to the
  day prior to the payment at a per annum rate equal to the internal rate of
  return earned by the Benmark Plan on the amount contributed.
 
    (c) FCB shall use its best efforts to obtain prior to the Closing the
  consent of each participant, other than J. Steven Walraven, in the
  Executive Private Pension Plan described in Section 4.8(f) of the FCB
  Disclosure Memorandum (the "EPP") to the modification of the EPP with
  respect to all participants other than Mr. Walraven effective as of the
  Effective Time, as described below. Following the Effective Time, NCBC
  shall maintain the EPP for the benefit of Mr. Walraven and shall make all
  contributions to the EPP required to provide Mr. Walraven with the benefits
  to which he is entitled pursuant to the EPP as described in that certain
  Executive Private Pension Agreement dated April 1, 1997, between Mr.
  Walraven and the FCB Bank Subsidiary and in that certain Officer's Benefit
  Statement dated as of February 17, 1998, between Mr. Walraven and the FCB
  Bank Subsidiary. As modified, the EPP shall provide that each participant
  in the EPP who consents to the modification shall be entitled to receive
  the amounts set forth below at the times set forth below:

  Except as provided in the following sentence, the amount payable at Normal
  Retirement Age (as defined in the Executive Private Pension Agreement
  between the Bank and each participant) shall be payable in accordance with
  the provisions of Articles III and IV of the Executive Private Pension
  Agreement between the Bank and each participant (including, without
  limitation, the provisions that contemplate the payment of such amount to
  the participant as a "Disability Benefit" or a "Death Benefit").
  Notwithstanding the previous sentence, if any participant leaves the employ
  of the Bank prior to his or her normal retirement date (other than because
  of death, disability or termination by the Bank for any reason other than
  for "cause" (as defined herein)), such participant shall be paid, in a lump
  sum, the amount shown in the table above as the "Amount Payable upon Early
  Termination" as soon as practicable following his or her termination and
  shall have no further rights pursuant to the EPP. If such participant
  leaves the Bank prior to Normal Retirement Age due to death or disability
  or due to dismissal by the Bank for any reason than for "cause", then the
  Amount Payable at Normal Retirement Age shall be payable in accordance with
  the provisions of Articles III and IV of the EPP; provided, however, that
  any "Early Retirement Benefit" (as defined in the EPP) shall be paid
  commencing on the Normal Retirement Date. "Cause" shall mean (i) conduct by
  a participant that amounts to fraud, material dishonesty, gross negligence
  or willful misconduct in the performance of participant's duties; (ii) the
  conviction (from which no appeal may be, or is, timely taken) of the
  participant of a felony; (iii) the initiation of suspension or removal
  proceedings against the participant by federal or state regulatory
  authorities under lawful authority pursuant to provision of federal or
  state law or regulation; or (iv) the knowing violation of federal or state
  banking laws or regulations. By consenting to the modification of the EPP
  as described above, each participant will agree that (i) neither the Bank
  nor any successor in interest to the Bank shall have any obligation to make
  contributions to the EPP following the Effective Time; (ii) the participant
  shall have only those rights with
 
                                     I-30
<PAGE>
 
  respect to the EPP described above; and (iii) the participant's rights to
  receive benefits from the EPP shall remain subject to the forfeiture
  provisions of Section 3.5 of the applicable Executive Private Pension
  Agreement. Following the Effective Time, NCBC shall maintain the EPP
  (without making further financial contributions thereto) to the extent
  required to provide the benefits to the participants as described above.
 
  7.14 D&O Coverage. At the Effective Time, NCBC will provide, errors and
omissions insurance coverage for FCB's directors and officers, at its
election, either (i) by purchasing continuation coverage under FCB's current
policy for a period not less than six (6) years after the Effective Time, or
(ii) obtain coverage under NCBC's current policy to provide coverage for FCB's
directors and officers on a prior acts basis for a period not less than six
(6) years prior to the Effective Time.
 
  7.15. Indemnification.
 
    (a) With respect to all claims brought during the period of three (3)
  years after the Effective Time, NCBC shall indemnify, defend and hold
  harmless present and former directors, officers, employees and agents of
  FCB and FCB Companies (the "FCB Entities") (each an "Indemnification
  Party") against all Liabilities arising out of actions or omissions arising
  out of the Indemnified Party's service or services as directors, officers,
  employees or agents of an Investor Entity, or at the request of an Investor
  Entity, of another corporation, partnership, joint venture, trust or other
  enterprise occurring at or prior to the Effective Time (including
  transactions contemplated by this Agreement) to the fullest extent
  permitted under Georgia Law and the Articles of Incorporation and Bylaws of
  FCB as in effect on the date hereof, including provisions relating to
  advances of expenses incurred in the defense of any Litigation and whether
  or not any FCB Company or NCBC is insured against any such matter. Without
  limiting the foregoing, in any case in which approval by the Surviving
  Corporation is required to effectuate any indemnification, the Surviving
  Corporation shall direct, at the election of the Indemnified Party, that
  the determination of any such approval shall be made by independent counsel
  mutually agreed upon between NCBC and the Indemnified Party.
 
    (b) Any Indemnified Party wishing to claim indemnification under
  paragraph (a) of this Section 7.15, upon learning of any such Liability of
  Litigation, shall promptly notify NCBC thereof. In the event of any such
  Litigation (whether arising before or after the Effective Time), (i) the
  Surviving Corporation shall have the right to assume the defense thereof
  and the Surviving Corporation shall not be liable to such Indemnified
  Parties for any legal expenses of other counsel or any other expenses
  subsequently incurred by such Indemnified Parties in connection with the
  defense thereof, except that if the Surviving Corporation elects not to
  assume such defense or counsel for the Indemnified Parties advised that
  there are substantive issues which raise conflicts of interest between the
  Surviving Corporation and the Indemnified Parties, the Indemnified Parties
  may retain counsel satisfactory to them, and the Surviving Corporation
  shall be obligated pursuant to this paragraph (b) to pay for only one firm
  of counsel for all Indemnified Parties in any jurisdiction, (ii) the
  Indemnified Parties will cooperate in the defense of any such Litigation,
  and (iii) the Surviving Corporation shall not be liable for any settlement
  effected without its prior written consent; and provided further that the
  Surviving Corporation shall not have any obligation thereunder to any
  Indemnified Party when and if a court of competent jurisdiction shall
  determine, and such determination shall have become final, that the
  indemnification of such Indemnified Party in the manner contemplated hereby
  is prohibited by applicable law.

  8.1 Conditions to Obligations of Each Party. The respective obligations of
each Party to perform this Agreement and consummate the Merger and the other
transactions contemplated hereby are subject to the satisfaction of the
following conditions, unless waived by both Parties pursuant to Section 10.6
of this Agreement:
 
 
                                     I-31
<PAGE>
 
    (a) Shareholder Approval. The shareholders of FCB shall have approved
  this Agreement and the Plan of Merger and the consummation of the
  transactions contemplated hereby and thereby, including the Merger, as and
  to the extent required by law, by the provisions of any governing
  instruments.
 
    (b) Regulatory Approvals. All Consents of, filings and registrations
  with, and notifications to, all Regulatory Authorities required for
  consummation of the Merger shall have been obtained or made and shall be in
  full force and effect and all waiting periods required by law shall have
  expired. No Consent obtained from any Regulatory Authority which is
  necessary to consummate the transactions contemplated hereby shall be
  conditioned or restricted in a manner, which in the reasonable judgment of
  the Board of Directors of either party would so materially adversely impact
  the financial or economic benefits of the transactions contemplated by this
  Agreement that, had such condition or requirement been known, either party
  would not, in its reasonable judgment, have entered into this Agreement.
 
    (c) Consents. Each Party shall have obtained any and all Consents
  required for consummation of the Merger (other than those referred to in
  Sections 8.1(b) and 8.1(c) of this Agreement) or for the preventing of any
  default under any contract or permit of such Party which, if not obtained
  or made, is reasonably likely to have, individually or in the aggregate, a
  Material Adverse Effect on such Party.
 
    (d) Legal Proceedings. No court or government or regulatory authority of
  competent jurisdiction shall have enacted, issued, promulgated, enforced or
  entered any law or order (whether temporary, preliminary or permanent) or
  taken any other action which prohibits, restricts or makes illegal
  consummation of the transactions contemplated by this Agreement and the
  Plan of Merger.
 
    (e) Registration Statement. The Registration Statement shall be effective
  under the 1933 Act, no stop orders suspending the effectiveness of the
  Registration Statement shall have been issued, no action, suit, proceeding
  or investigation by the SEC to suspend the effectiveness thereof shall have
  been initiated and be continuing, and all necessary approval under state
  securities laws or the 1933 Act, or 1934 Act relating to the issuance or
  trading of the shares of NCBC Common Stock pursuant to the Merger shall
  have been received.
 
    (f) Exchange Listing. The shares of NCBC Common Stock issuable pursuant
  to the Merger shall have been approved for listing on the NASDAQ, subject
  to official notice of issuance.
 
    (g) Tax Matters. Each of the Parties shall have received an opinion from
  King & Spalding in form and substance reasonably satisfactory to such
  Party, dated the Effective Time, substantially to the effect that, on the
  basis of facts, representations and assumptions set forth in such opinion
  which are consistent with the state of facts existing at the Effective
  Time, for federal income tax purposes:
 
      (i) The Merger will be treated as a reorganization within the meaning
    of Section 368(a) of the IRC;
 
      (ii) No gain or loss will be recognized by NCBC or FCB as a result of
    the Merger;
 
      (iii) No gain or loss will be recognized by the shareholders of FCB
    upon the exchange of FCB Common Stock for NCBC Common Stock pursuant to
    the Merger (except with respect to cash received in lieu of a
    fractional share interest in NCBC Common Stock) or by the holders of
    FCB Options upon the conversion of such options into rights with
    respect to NCBC Common Stock; and
 
      (iv) The aggregate tax basis of NCBC Common Stock received by a FCB
    shareholder pursuant to the Merger will be the same as the aggregate
    tax basis of the FCB Common Stock surrendered in exchange therefor
    (excluding any basis allocable to a fractional share of NCBC Common
    Stock for which cash is received).
 
      In rendering such opinion, King & Spalding may require and rely upon
    representations and covenants, including those contained in
    certificates of officers of NCBC, FCB, and others, reasonably
    satisfactory in form and substance to such counsel.

    (i) Employment Agreements. NCBC and each of J. Steven Walraven and Rodney
  L. Grizzle shall have entered into an Employment Agreement for a term of

  favorable than their respective compensation and job responsibilities as of

  8.2 Conditions to Obligations of NCBC. The obligations of NCBC to perform
this Agreement and consummate the Merger and the other transactions
contemplated hereby are subject to the satisfaction of the following

  Agreement shall be assessed as of the date of this Agreement and as of the
  Effective Time with the same effect as though all such representations and
  warranties had been made on and as of the Effective Time (provided that
  representations and warranties which are confined to a specified date shall
  speak only as of such date). The representations and warranties of FCB set
  forth in Section 4.3 of this Agreement shall be true and correct (except
  for inaccuracies which are de minimis in amount). The representations and
  warranties of FCB set forth in Sections 4.20, 4.21 and 4.22 of this
  Agreement shall be true and correct in all material respects. There shall
  not exist inaccuracies in the representations and warranties of FCB set
  forth in this Agreement (including the representations and warranties set
  forth in Sections 4.3, 4.20, 4.21 and 4.22), such that the aggregate effect
  of such inaccuracies has, or is reasonably likely to have, a Material
  Adverse Effect on FCB.
 
    (b) No Material Adverse Effect. There shall have been no Material Adverse
  Effect on FCB's or FCB Bank Subsidiary's financial condition since March
  31, 1998.

  8.2(b) of this Agreement have been satisfied, and (ii) certified copies of
  resolutions duly adopted by FCB's Board of Directors and shareholders
  evidencing the taking of all corporate action necessary to authorize the

  Merger, and the consummation of the transactions contemplated hereby and
  thereby, all in such reasonable detail as NCBC and its counsel shall
  reasonably request.
 
    (e) Affiliates Agreements. NCBC shall have received from each affiliate
  of FCB the affiliates letter referred to in Section 7.12 of this Agreement,
  to the extent necessary to assure in the reasonable judgment of NCBC that
  the transactions contemplated hereby will qualify for pooling-of-interests
  accounting treatment.
 
    (f) Legal Opinion. FCB shall have delivered to NCBC an opinion of
  Troutman Sanders LLP, counsel to FCB, dated as of the Closing Date,
  addressed to and in form and substance satisfactory to NCBC, to the effect
  that:
 
      (i) FCB 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.
 
      (ii) FCB Bank Subsidiary is a financial institution 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
    own and use its Assets.
 
      (iii) The execution, delivery and performance of this Agreement and
    the Plan of Merger, as appropriate, and the consummation of the
    transactions contemplated herein and therein, including the
 
                                     I-33
<PAGE>
 
    Merger, have been duly and validly authorized by all necessary
    corporate and shareholder action in respect thereof on the part of FCB.
 
      (iv) The execution and delivery by FCB of the Agreement do not, and
    if FCB were 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 FCB or, to our Knowledge but
    without any independent investigation, result in any breach of, or
    default or acceleration under any mortgage, agreement, lease,
    indenture, or other instrument, order, judgment or decree to which FCB
    is a party or by which it is bound.
 
      (v) The Agreement has been duly and validly executed and delivered by
    FCB, and assuming valid authorization, execution and delivery by NCBC
    constitutes a valid and binding agreement of FCB enforceable in
    accordance with its terms, except as enforceability may be limited by
    bankruptcy, insolvency, reorganization, moratorium or similar laws
    affecting creditors' rights generally and subject to the application of
    equitable principles and judicial discretion; provided, however, that
    we express no opinion as to the availability of the equitable remedy of
    specific performance.
 
    (g) Maintenance of Certain Covenants, Etc. At the time of Closing,
 
      (i) Exclusive of any securities gains or losses pursuant to FAS 115,
    total consolidated stockholders' equity of FCB shall not be less than
    $8,330,000;
 
      (ii) FCB shall own, free and clear of any liens, not less than 100%
    of the outstanding capital stock of FCB Bank Subsidiary; and
 
      (iii) From and after the Balance Sheet Date, there shall have been no
    extraordinary sale of assets, nor any material investment portfolio
    restructuring by either FCB Company.
 
      The financial criteria and calculations set forth above shall be
    determined in accordance with GAAP assuming that FCB and FCB Bank
    Subsidiary shall have been operated consistently in the normal course
    of their respective businesses; provided, however, that the effects of
    any balance sheet expansion through abnormal, unusual, nonrecurring or
    out-of-the-ordinary borrowings or by the realization of extraordinary
    or nonrecurring gains otherwise than in the ordinary course of business
    or other income from the disposition of assets or liabilities or
    through similar transactions shall be eliminated from the calculations.
 
    (h) Non-Compete Agreements. Each of H. Boyd Pettit, III, J. Steven
  Walraven and Rodney L. Grizzle shall have entered into, and FCB shall have
  used its best efforts to cause each other director of FCB and each chairman
  of the board and each president or chief executive officer of FCB Bank
  Subsidiary to enter into, a non-compete agreement with NCBC and FCB Bank
  Subsidiary substantially in the form of the non-compete agreement which is
  annexed hereto as Exhibit 2.
 
    (i) Consents. FCB shall have obtained and shall have furnished to NCBC
  the consent of each participant in the Benmark Plan on the Closing Date,
  other than Mr. Michael L. McPherson, to the termination of the Benmark Plan

Agreement and the Plan of Merger and consummate the Merger and the other
transactions contemplated hereby are subject to the satisfaction of the
following conditions, unless waived by FCB pursuant to Section 10.6(b) of this
Agreement.

  the accuracy of the representations and warranties of NCBC set forth in
  this Agreement shall be assessed as of the date of this Agreement and as of
  the Effective Time with the same effect as though all such representations
  and warranties had been made on and as of the Effective Time (provided that
  representations and warranties which are confined to a specified date shall
  speak only as of such date). The representations and warranties
 
                                     I-34
<PAGE>
 
  of NCBC set forth in Section 5.3 of this Agreement shall be true and
  correct (except for inaccuracies which are de minimis in amount). The

  shall reasonably request.
 
    (d) Legal Opinion. NCBC shall have delivered to FCB an opinion of
  counsel, which may be in-house counsel of NCBC, dated as of the Closing
  Date, addressed to and in form and substance satisfactory to FCB, to the
  effect that:
 
      (i) NCBC is a Tennessee corporation, duly organized, validly existing

  consideration to be received by the FCB Record Holders pursuant to the
  terms and conditions of this Agreement is fair to the shareholders of FCB
  from a financial point of view, and such fairness opinion shall not have

                                  TERMINATION
 
  9.1 Termination. Notwithstanding any other provision of this Agreement, and
notwithstanding the approval of this Agreement by the shareholders of NCBC or
FCB, this Agreement and the Plan of Merger may be terminated and the Merger
abandoned at any time prior to the Effective Time:
 
    (a) By mutual consent of the Board of Directors of NCBC and the Board of
  Directors of FCB; or
 
 
                                     I-35
<PAGE>
 
    (b) By the Board of Directors of either Party (provided that the
  terminating Party is not then in breach of any representation or warranty
  contained in this Agreement under the applicable standard set forth in
  Section 8.2(a) of this Agreement in the case of FCB and Section 8.3(a) in
  the case of NCBC or in material breach of any covenant or other agreement
  contained in this Agreement) in the event of an inaccuracy of any
  representation or warranty of the other Party contained in this Agreement
  which cannot be or has not been cured within thirty (30) days after the
  giving of written notice to breaching Party of such inaccuracy and which
  inaccuracy would provide the terminating Party the ability to terminate the
  Merger under the applicable standard set forth in Section 8.2(a) of this
  Agreement in the case of FCB and Section 8.3(a) of this Agreement in the
  case of NCBC; or
 
    (c) By the Board of Directors of either Party (provided that the
  terminating Party is not then in breach of any representation or warranty
  contained in this Agreement under the applicable standard set forth in
  Section 8.2(a) of this Agreement in the case of FCB and Section 8.3(a) in
  the case of NCBC or in material breach of any covenant or other agreement
  contained in this Agreement) in the event of a material breach by the other
  Party of any covenant or agreement contained in this Agreement which cannot
  be or has not been cured within thirty (30) days after the giving of
  written notice to the breaching Party of such breach; or
 
    (d) By the Board of Directors of either Party in the event (i) any
  consent of any Regulatory Authority required for consummation of the Merger
  shall have been denied by final nonappealable action of such Regulatory
  Authority or if any action taken by such Regulatory Authority is not
  appealed within the time limit for appeal or (ii) the shareholders of FCB
  fail to vote their approval of this Agreement and the transactions
  contemplated hereby as required by the Georgia Code and FCB's Charter and
  Bylaws; or
 
    (e) By the Board of Directors of either Party in the event that the
  Merger shall not have been consummated by November 30, 1998, if the failure
  to consummate the transactions contemplated hereby on or before such date
  is not caused by any willful breach of this Agreement by the Party electing
  to terminate pursuant to this Section 9.1(e) and further, if NCBC shall
  have filed all applications necessary to obtain the necessary Consents of
  banking Regulatory Authorities within sixty (60) days of the date hereof,
  and if the Closing shall not have occurred because of a delay caused by a
  bank Regulatory Authority in its review of the application before it, or by
  the SEC in its review of the Registration Statement to be filed by NCBC,
  then FCB shall, upon NCBC's written request, extend the November 30, 1998,
  date for a reasonable time, in no event less than thirty (30) days, in
  order for NCBC to obtain all Consents of bank Regulatory Authorities
  required and/or all Consents of the SEC and any other securities Regulatory
  Authorities, and for the expiration of any stipulated waiting periods; or
 
    (f) By the Board of Directors of either Party (provided that the
  terminating Party is not then in breach of any representation or warranty
  contained in this Agreement under the applicable standard set forth in
  Section 8.2(a) of this Agreement in the case of FCB and Section 8.3(a) in
  the case of NCBC or in material breach of any covenant or other agreement
  contained in this Agreement) in the event that any of the conditions
  precedent to the obligations of such Party to consummate the Merger cannot
  be satisfied or fulfilled by the date specified in Section 9.1(e) of this
  Agreement as the same may be extended pursuant to Section 9.1(e).
 
  9.2 Effect of Termination. In the event of the termination and abandonment
of this Agreement pursuant to Section 9.1 of this Agreement, this Agreement
and the Plan of Merger shall become void and have no effect, except that (i)
the provisions of this Section 9.2 and Article 10 and Sections 7.6(b) and 7.8

  FCB under this Agreement, except any condition which, if not satisfied,

  of any provision hereof shall in no manner affect the right of such Party
  at a later time to enforce the same or any other provision of this
  Agreement. No waiver of any condition or of the breach of any term
  contained in this Agreement in one or more instances shall be deemed to be
  or construed as a further or continuing waiver of such condition or breach

August 7, 1998
 
Board of Directors
First Community Bancorp, Inc.
827 Joe Frank Harris Parkway, S.E.
Cartersville, Georgia 30120
 
Gentlemen:
 
  You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of First Community Bancorp, Inc. (the "Company") of
the Exchange Ratio in connection with its proposed merger with National
Commerce Bancorporation ("NCBC") (the "Transaction") pursuant to and in
accordance with the terms of that certain Agreement and Plan of Merger (the
"Agreement") entered into by and between NCBC and the Company. Capitalized
terms used herein and not otherwise defined shall have the meanings ascribed
to them in the Agreement.
 
  You have advised us that, pursuant to the Agreement, NCBC and the Company
will merge (the "Merger") with and into NCBC and that the Company's banking
subsidiary will become a wholly owned bank subsidiary of NCBC. Each share of
the Company's Common Stock (excluding shares held by (i.) Company shareholders
who perfect their dissenter' rights or by (ii.) the Company or any of its
subsidiaries or by NCBC or any of its subsidiaries, in each case other than in
a fiduciary capacity or as a result of debts previously contracted) issued and
outstanding at the Effective Time shall be converted into 3.2684 shares of
NCBC Common Stock, subject to adjustment as set forth in the Agreement.
 
  Morgan Keegan & Company, Inc. ("Morgan Keegan"), as part of its investment
banking business, is regularly engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for various purposes. We have been retained by the Board of
Directors of the Company for the purpose of and will receive a fee for,
rendering this opinion. We have not advised any party in connection with the
Transaction other than the Company and we make no recommendation to the
shareholders of the Company.
 
  In connection with our opinion, we have (1) reviewed the Agreement; (2) held
discussions with various members of management and representatives of the
Company and NCBC concerning each company's historical and current operations,
financial condition and prospects; (3) reviewed historical consolidated
financial and operating data that was publicly available or furnished to us by
the Company and NCBC; (4) reviewed internal financial analyses, financial and
operating forecasts, reports and other information prepared by officers and
representatives of the Company; (5) reviewed certain publicly available
information with respect to certain other companies that we believe to be
comparable to the Company and NCBC and the trading markets for such other
companies' securities; (6) reviewed certain publicly available information
concerning the terms of certain other transactions that we deemed relevant to
our inquiry; (7) considered the relative contributions of the Company and NCBC
to the combined company; and (8) conducted such other financial studies,
analyses and investigations as we deemed appropriate for the purpose of this
opinion.
 
  In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and
other information provided us or publicly available and have assumed and
relied upon the representations and warranties of the Company and NCBC
contained in the Agreement. We have not been engaged to, and have not
independently attempted to, verify any of such information. We have also
relied upon the managements of the Company and NCBC as to the reasonableness
and achievability of the financial and operating projections and the
assumptions and bases therefor provided to us and, with your consent, we have
assumed that such projections reflect the best currently available estimates
and judgments of such
 
                                     II-1
<PAGE>
 
respective managements of the Company and NCBC and that such projections and
forecasts will be realized in the amounts and time periods currently estimated
by the managements of the Company and NCBC. We have not been engaged to assess
the achievability of such projections or the assumptions on which they were
based and express no view as to such projections or assumptions. In addition,
we have not conducted a physical inspection or appraisal of any of the assets,
properties or facilities of either the Company or NCBC nor have we been
furnished with any such evaluation or appraisal. We have also assumed that the
conditions to the Transaction would be consummated on a timely basis in the
manner contemplated in the Agreement. Our opinion is based upon analyses of
the foregoing factors in light of our assessment of general economic,
financial and market conditions as they exist and can be evaluated by us as of
the date hereof. We express no opinion as to the price or trading range at
which shares of NCBC Common Stock will trade following the date hereof, or the
price or trading range at which NCBC Common Stock will trade upon completion
of the Transaction.
 
  Morgan Keegan has previously provided investment banking and fixed income
services to the Company. In the ordinary course of our business, we serve as a
market maker for the NCBC Common Stock and trade shares for our own account
and the accounts of our customers. Accordingly, we may at any time hold long
or short positions in NCBC Common Stock.
 
  It is understood that this opinion is not to be quoted or referred to, in
whole or in part (including excerpts or summaries), in any filing, report,
document, release or other communication used in connection with the
Transaction (unless required to be quoted or referred to by applicable
regulatory requirements), nor shall this opinion be used for any other
purposes, without our prior written consent, which consent shall not be
unreasonably withheld. Furthermore, our opinion is directed to the Board of
Directors of the Company and does not constitute a recommendation to any
shareholder of the Company as to how such shareholder should vote at the
shareholders' meeting to be held in connection with the Transaction.
 
  Based upon and subject to the foregoing and based upon such other matters as
we consider relevant, it is our opinion that, as of the date hereof, the
Exchange Ratio is fair, from a financial point of view, to the Company's
shareholders.
 
                                          Yours very truly,
 
                                          /s/ Morgan Keegan & Company, Inc.

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

  (a) Except as provided in Code Section 14-2-1327, within ten days of the

  (b) The offer of payment must be accompanied by:
 
    (1) The corporation's balance sheet as of the end of a fiscal year ending

  (a) A dissenter may notify the corporation in writing of his own estimate of
the fair value of his shares and amount of interest due, and demand payment of
his estimate of the fair value of his shares and interest due, if:
 
    (1) The dissenter believes that the amount offered under Code Section 14-
  2-1325 is less than the fair value of his shares or that the interest due
  is incorrectly calculated; or
 
    (2) The corporation, having failed to take the proposed action, does not
  return the deposited certificates or release the transfer restrictions
  imposed on uncertificated shares within 60 days after the date set for
  demanding payment.
 
  (b) A dissenter waives his or her right to demand payment under this Code

                         Judicial Appraisal of Shares
 
14-2-1330. COURT ACTION.
 
  (a) If a demand for payment under Code Section 14-2-1327 remains unsettled,
the corporation shall commence a proceeding within 60 days after receiving the
payment demand and petition the court to determine the fair value of the
shares and accrued interest. If the corporation does not commence the
proceeding within the 60 day period, it shall pay each dissenter whose demand
remains unsettled the amount demanded.
 
  (b) The corporation shall commence the proceeding, which shall be a nonjury
equitable valuation proceeding, in the superior court of the county where a
corporation's registered office is located. If the surviving corporation is a
foreign corporation without a registered office in this state, it shall
commence the proceeding in the county in this state where the registered
office of the domestic corporation merged with or whose shares were acquired
by the foreign corporation was located.
 
  (c) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the proceeding, which
shall have the effect of an action quasi in rem against their shares. The
corporation shall serve a copy of the petition in the proceeding upon each
dissenting shareholder who is a resident of this state in the manner provided
by law for the service of a summons and complaint, and upon each nonresident
dissenting shareholder either by registered or certified mail or by
publication, or in any other manner permitted by law.
 
  (d) The jurisdiction of the court in which the proceeding is commenced under
subsection (b) of this Code section is plenary and exclusive. The court may
appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value. The appraisers have the powers
described in the order appointing them or in any amendment to it. Except as
otherwise provided in this chapter, Chapter 11 of Title 9, known as the
"Georgia Civil Practice Act," applies to any proceeding with respect to
dissenters' rights under this chapter.
 
  (e) Each dissenter made a party to the proceeding is entitled to judgment
for the amount which the court finds to be the fair value of his shares, plus
interest to the date of judgment.
 
14-2-1331. COURT COSTS AND COUNSEL FEES.
 
  (a) The court in an appraisal proceeding commenced under Code Section 14-2-
1330 shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court, but not
including fees and expenses of attorneys and experts for the respective
parties. The court shall assess the costs against the corporation, except that
the court may assess the costs against all or some of the dissenters, in
amounts the court finds equitable, to the extent the court finds the
dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under Code Section 14-2-1327.
 
                                     III-5
<PAGE>
 
  (b) The court may also assess the fees and expenses of attorneys and experts
for the respective parties, in amounts the court finds equitable:
 
    (1) Against the corporation and in favor of any or all dissenters if the
  court finds the corporation did not substantially comply with the
  requirements of Code Sections 14-2-1320 through 14-2-1327; or
 
    (2) Against either the corporation or a dissenter, in favor of any other
  party, if the court finds that the party against whom the fees and expenses
  are assessed acted arbitrarily, vexatiously, or not in good faith with
  respect to the rights provided by this article.
 
  (c) If the court finds that the services of attorneys for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to these attorneys reasonable fees to be paid out of the
amounts awarded the dissenters who were benefited.
 
14-2-1332. LIMITATION OF ACTIONS.
 
  No action by any dissenter to enforce dissenters' rights shall be brought
more than three years after the corporate action was taken, regardless of
whether notice of the corporate action and of the right to dissent was given
by the corporation in compliance with the provisions of Code Section 14-2-1320
and Code Section 14-2-1322.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20: INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The following summary is qualified in its entirety by reference to the
complete text of the statute, Charter, Bylaws and agreements referred to
below.
 
  The Registrant's Bylaws provide that the Registrant will indemnify any
person, who is made a party to a suit by or in the right of the Registrant by
reason of the fact that he is or was an officer or director of the Registrant,
against amounts paid in settlement and reasonable expenses incurred as a
result of such suit or proceeding or any appeal therein to the extent
permitted by, and in the manner provided by, Tennessee law. The Registrant
will indemnify any person made, or threatened to be made, a party to a suit
other than by or in the right of any corporation, by reason of the fact that
he was an officer or director of the Registrant or served such other
corporation in any capacity, against judgments, fines, amounts paid in
settlement and reasonable expenses incurred as a result of such suit or
proceeding or any appeal therein, if such director or officer acted in good
faith for a purpose he reasonably believed to be in the best interest of the
Registrant and, in criminal actions or proceedings, in addition, had no
reasonable cause to believe that his conduct was unlawful, and to the extent
permitted by, and in the manner provided by, Tennessee law.
 
  The Registrant's Charter provides that no director of the Registrant shall
be personally liable to the Registrant or its shareholders for monetary
damages for breach of fiduciary duty as a director, except (i) for any breach
of the director's duty of loyalty to the Registrant or its shareholders, (ii)
for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, or (iii) for unlawful distributions
under the laws of Tennessee. Under Part 5 of Article 18 of the Tennessee
Securities Act, a corporation may indemnify a director, officer, employee or
agent of the corporation who is made a party to a proceeding against liability
incurred in the proceeding if (1) he conducted himself in good faith and (2)
he reasonably believed (a) that his conduct was in the best interest of the
corporation in the case of conduct in his official capacity, (b) that his
conduct was at least not opposed to the corporation's best interest in all
other cases, and (c) he had no reasonable cause to believe his conduct was
unlawful, in the case of a criminal proceeding. A corporation may not
indemnify a director in connection with a proceeding by or in the right of the
corporation in which the director was adjudged liable to the corporation or in
connection with any other proceeding charging improper personal benefit to
him, in which he was adjudged liable on the basis that personal benefit was
improperly received by him.
 
  The Registrant maintains a directors and officers liability insurance
policy. Such policy has a deductible of $150,000 and an annual per occurrence
and aggregate cap on coverage of $20 million. In addition, the Registrant
maintains a general liability insurance policy with an annual per occurrence
and aggregate cap of $20 million.

  An index to Exhibits appears at pages II-5 through II-6 hereof.
 
ITEM 22: UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, 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 Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by 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
 
                                     II-1

precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  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 section 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.
 
  The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
  The Registrant undertakes that every prospectus (i) that is filed pursuant
to the immediately preceding paragraph or (ii) that purports to meet the
requirements of section 10(a)(3) of the Securities Act of 1933 and is used in
connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the registration statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
  The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Proxy
Statement/Prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form,
within one business day of receipt of such request, and to send the
incorporated documents by first class mail or other equally prompt means. This
includes information contained in documents filed subsequent to the effective
date of the registration statement through the date of responding to the
request.
 
  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:  Form S-4 Registration Statement Relating to
          1,608,688 Shares of Common Stock, Par Value 
          $2.00 per Share, of National Commerce Bancorporation
          ----------------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel for National Commerce Bancorporation, a Tennessee
corporation ("NCBC"), in connection with the preparation and filing of the
Registration Statement on Form S-4 (the "Registration Statement") filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
relating to 1,608,688 shares of NCBC common stock, par value $2.00 per share, to
be issued in connection with the Agreement and Plan of Merger, dated as of 
August 5, 1998 (the "Merger Agreement"), by and between NCBC and First Community
Bancorp, Inc.

     In our capacity as such counsel, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of such corporate records
of NCBC, such agreements and instruments, such certificates of public officials,
officers of NCBC and other persons, and such other documents as we have deemed
necessary or appropriate as a basis for the opinions hereinafter expressed.  In
such examinations, we have assumed the genuineness of all signatures, the legal
capacity of all natural persons, the authenticity and completeness of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified, conformed, photostatic or facsimile
copies, and the authenticity of the originals of such copies, and we have
assumed all certificates of public officials to have been properly given and to
be accurate.

     As to factual matters relevant to this opinion letter, we have relied upon
the representations and warranties as to factual matters contained in
certificates and statements of officers of NCBC and certain public officials.
Except to the extent expressly set forth herein, we have made no independent
investigations with regard thereto, and, accordingly, we do not express any
opinion as to matters that might have been disclosed by independent
verification.

     On the basis of the foregoing, and subject to the limitations set forth
herein, we are of the opinion that the shares of Common Stock of NCBC, par value
$2.00 per share, issuable in connection

Page 2

with the Merger Agreement have been duly authorized and, when issued in
accordance with the terms of the Merger Agreement as described in the
Registration Statement, will be validly issued, fully paid and nonassessable by
the Company.

     We consent to the filing of this opinion letter as an exhibit to the
Registration Statement and to any related registration statement subsequently
filed by NCBC pursuant to Rule 462(b) of the Act and to the use of our name
under the heading "Legal Opinions" in the Prospectus constituting a part
thereof.  In giving such consent, we do not thereby admit that we are within the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission thereunder.

     This opinion letter is being furnished by us to NCBC and the Commission
solely for the benefit of NCBC and the Commission in connection with the
Registration Statement and is not to be used, circulated, quoted or otherwise
relied upon by any other person, or by NCBC or the Commission for any other
purposes, without our express written consent.  The only opinion rendered by us
consists of those matters set forth in the fourth paragraph hereof, and no
opinion may be implied or inferred beyond those expressly stated.  This opinion
letter is rendered as of the date hereof, and we have no obligation to update
this opinion letter.

                                    Sincerely,

                                    KING & SPALDING

     Re:  Federal Income Tax Consequences of Merger of First Community Bancorp,
          Inc. with and into National Commerce Bancorporation

Ladies and Gentlemen:

     We have acted as counsel to National Commerce Bancorporation ("NCBC") in
connection with the Merger (the "Merger") of First Community Bancorp, Inc.
("FCB") with and into NCBC, pursuant to the Agreement and Plan of Merger dated
as of August 5, 1998 (the "Agreement") by and between NCBC and FCB. You have
requested our opinion, in our capacity as counsel to NCBC, regarding certain
federal income tax consequences of the Merger.

     We understand that our opinion will be referred to in the Proxy
Statement/Prospectus that forms part of the Registration Statement on Form S-4
filed with the Securities and Exchange Commission in connection with the Merger.
We hereby consent to such use of our opinion.

     All capitalized terms used herein without definition have the respective
meanings specified in the Agreement. All references herein to the Code are to
the United States Internal Revenue Code of 1986, as amended.

                             INFORMATION RELIED ON
                             ---------------------

     In rendering the opinion expressed herein, we have examined such documents
as we have deemed appropriate, including the Agreement. In our examination of
such documents, we have assumed, with your consent, that all documents submitted
to us as photocopies or telecopies 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. We also have obtained such additional information and
representations as we have deemed relevant and necessary. However, we have not
yet obtained written certificates from NCBC and FCB to verify certain facts that
we have assumed in rendering this opinion. 
<PAGE>
 
National Commerce Bancorporation
First Community Bancorp, Inc.
August 7, 1998
Page 2
 
Before rendering our opinion in connection with the closing, we intend to obtain
appropriate written certificates to confirm certain material facts that we have
assumed herein.

     In view of the foregoing, we have assumed that the following statements are
true on the date hereof and will be true at the time of the Merger:

     (1) The Merger will be consummated in compliance with the material terms of
the Agreement and none of the material terms and conditions therein have been
waived or modified and neither NCBC nor FCB has a plan or intention to waive or
modify any such material term or condition.

     (2)  The fair market value of the NCBC Common Stock and other consideration
received by each FCB shareholder will be approximately equal to the fair market
value of the FCB Common Stock surrendered by such shareholder in the Merger.

     (3) Neither FCB nor any person related to FCB has acquired or will acquire,
in connection with the Merger, any FCB Common Stock from the FCB shareholders
prior to the Effective Time. For purposes of this assumption, a person is
related to FCB if it is (i) a corporation as to which FCB owns, actually or
constructively, fifty percent or more of the total voting power or total value
of the shares of all classes of stock outstanding, or (ii) a corporation which
owns, actually or constructively, fifty percent or more of the total voting
power or total value of all shares of all classes of stock of FCB. A person will
be deemed related to FCB for this purpose if such relationship exists either
immediately before or immediately after such acquisition, and a person that is a
partner in a partnership will be deemed to own or have acquired any stock that
such partnership acquired in accordance with the partner's interest in the
partnership.

     (4) Neither NCBC nor any person related to NCBC has acquired or will
acquire, in connection with the Merger, any FCB Common Stock from the FCB
shareholders prior to the Effective Time. For purposes of this assumption, a
person is related to NCBC if it is (i) a member of its affiliated group within
the meaning of Section 1504 of the Code, (ii) a corporation as to which NCBC
owns, actually or constructively, fifty percent or more of the total voting
power or total value of the shares of all classes of stock outstanding, or (iii)
a corporation which owns, actually or constructively, fifty percent or more of
the total voting power or total value of all shares of all classes of stock of
NCBC. A person will be deemed related to NCBC for this purpose if such
relationship exists either immediately before or immediately after such
acquisition or arises in connection with the Merger, and a person that is a
partner in a partnership will be deemed to own or have acquired any stock that
such partnership acquired in accordance with the partner's interest in the
partnership.

     (5) Neither NCBC nor any person related to NCBC has any plan or intention
to reacquire any of the shares of NCBC Common Stock issued in the Merger. For
purposes of this assumption, a person is related to NCBC if it is (i) a member
of its affiliated group within the meaning of Section 1504 of the Code, (ii) a
corporation as to which NCBC owns, actually or constructively, fifty percent or
more of the total voting power or total value of the shares of all classes of
stock outstanding, or (iii) a corporation which owns, actually or
constructively, fifty percent or more of the total voting power or total value
of all shares of all classes of stock of 
<PAGE>
 
National Commerce Bancorporation

Page 3
 
NCBC. A person will be deemed related to NCBC for this purpose if such
relationship exists either immediately before or immediately after such
acquisition or arises in connection with the Merger, and a person that is a
partner in a partnership will be deemed to own or have acquired any stock that
such partnership acquired in accordance with the partner's interest in the
partnership.

     (6) The liabilities of FCB to be assumed by NCBC and the liabilities to
which the transferred assets of FCB are subject were incurred by FCB in the
ordinary course of its business.

     (7) NCBC, FCB and the shareholders of FCB will pay their respective
expenses, if any, incurred in connection with the Merger.

     (8) There is no intercorporate indebtedness existing between FCB and NCBC
that was or will be issued, acquired, or settled at a discount.

     (9) Neither FCB nor NCBC is a regulated investment company, a real estate
investment trust, or a corporation 50 percent or more of the value of whose
total assets (excluding cash, cash items, receivables and U.S. government
securities) are stock or securities and 80 percent or more of the value of whose
total assets are assets held for investment. For purposes of the 50 percent and
80 percent determinations under the preceding sentence, stock and securities in
any subsidiary shall be disregarded, and the parent corporation shall be deemed
to own its ratable share of the subsidiary's assets. A corporation shall be
considered a subsidiary for purposes of this paragraph if the parent owns 50
percent or more of the combined voting power of all classes of such
corporation's stock entitled to vote, or 50 percent or more of the total value
of shares of all classes of such corporation's stock outstanding.

     (10) FCB is not under the jurisdiction of a court in a case under Title 11
of the United States Code or a receivership, foreclosure, or similar proceeding
in a federal or state court.

     (11) The fair market value of the assets of FCB transferred to NCBC will
equal or exceed the sum of the liabilities assumed by NCBC plus the amount of
liabilities, if any, to which the transferred assets are subject.

     (12) NCBC has no plan or intention to sell or otherwise dispose of  any of
the assets acquired from FCB, except for dispositions made in the ordinary
course of business.

     (13) Following the Merger, NCBC will continue the historic business of FCB
or use a significant portion of FCB's historic business assets in a business.

     (14) None of the compensation received by any shareholder-employees of FCB
in contemplation of or as a result of the Merger will be separate consideration
for, or allocable to, any of their shares of FCB Common Stock; none of the
shares of NCBC Common Stock received by any shareholder-employees of FCB in
exchange for FCB Common Stock in the Merger will be separate consideration for,
or allocable to, any employment agreement; and the compensation paid to any
shareholder-employees pursuant to the Merger will be for services actually
rendered and 
<PAGE>
 
National Commerce Bancorporation
First Community Bancorp, Inc.
August 7, 1998
Page 4
 
will be commensurate with amounts paid to third parties bargaining at arm's
length for similar services.

     (15) The outstanding FCB Options have been granted by FCB as compensation
in connection with the provision of services to FCB and First Community Bank &
Trust by the FCB Option holders.

     (16) The payment of cash in lieu of fractional shares of NCBC Common Stock
is solely for the purpose of avoiding the expense and inconvenience to NCBC of
issuing fractional shares and does not represent separately bargained-for
consideration. The total cash consideration that will be paid in the Merger to
the FCB shareholders instead of issuing fractional shares of NCBC Common Stock
will not exceed one percent of the total consideration that will be issued in
the Merger to the FCB shareholders in exchange for their shares of FCB Common
Stock. The fractional share interest of each FCB shareholder will be aggregated
and no FCB shareholder will receive cash in an amount equal to or greater than
the value of one full share of NCBC Common Stock.

     (17) At the Effective Time, the aggregate fair market value of the NCBC
Common Stock issued to the FCB shareholders in the Merger will represent at
least fifty percent (50%) of the total value of the aggregate consideration
payable in the Merger to the FCB shareholders (including cash paid to FCB
shareholders who perfect their dissenters rights and cash paid in lieu of
fractional shares of NCBC Common Stock).

     (18) FCB will not, prior to the Effective Time, make any distributions with
respect to its stock which are of an extraordinary nature.


                                 OPINION
                                 -------

     Based upon the foregoing, it is our opinion that:

     (1) The Merger will be treated as a "reorganization" within the meaning of
Section 368(a)(1)(A) of the Code;

     (2) No gain or loss will be recognized by NCBC or FCB as a result of the
Merger;

     (3) No gain or loss will be recognized by the shareholders of FCB upon the
exchange of FCB Common Stock for NCBC Common Stock pursuant to the Merger
(except with respect to cash received in lieu of fractional share interests in
NCBC Common Stock) or by the holders of FCB Options upon the conversion of such
options into rights with respect to NCBC Common Stock;

     (4) The aggregate tax basis of the NCBC Common Stock received by a FCB
shareholder pursuant to the Merger will be the same as the aggregate tax basis
of the FCB 
<PAGE>
 
National Commerce Bancorporation
First Community Bancorp, Inc.
August 7, 1998
Page 5
 
Common Stock surrendered in exchange therefor (excluding any basis allocable to
a fractional share of NCBC Common Stock for which cash is received);

     (5) The holding period of the shares of  NCBC Common Stock received by a
FCB Shareholder will include the holding period or periods of the shares of FCB
Common Stock exchanged therefor, provided that the shares of FCB Common Stock
are held as a capital asset within the meaning of Section 1221 of the Code at
the Effective Time;

     (6) The receipt of cash in lieu of fractional shares of NCBC Common Stock
will be treated as if fractional shares were distributed as part of the exchange
and then were redeemed by NCBC; and

     (7) A FCB Shareholder who perfects his appraisal rights under Georgia law
and who receives payment in cash for the "fair value" of his shares of FCB
Common Stock will be treated as having exchanged such shares for cash in a
redemption subject to Section 302 of the Code, and the FCB Shareholder generally
will recognize capital gain or loss in such exchange equal to the difference
between the cash received and the tax basis of such shares.

     The opinion expressed herein is based upon existing statutory, regulatory,
and judicial authority, any of which may be changed at any time with retroactive
effect. In addition, our opinion is based solely on the documents that we have
examined, the additional information that we have obtained, and the statements
set out herein that we have assumed to be true on the day hereof and at the time
of the Merger. Our opinion cannot be relied upon if any of the material facts
contained in such documents or any such additional information is, or later
becomes, inaccurate or if any of the material statements set out herein is, or
later becomes, inaccurate. Finally, our opinion is limited to the tax matters
specifically covered thereby, and we have not been asked to address herein, nor
have we addressed herein, any other tax consequences of the Merger.


                                    Very truly yours,

                                    /s/ King & Spalding
