                         FIRST UNITED BANCSHARES, INC.
                                   PROSPECTUS

                                Par Value $1.00
 
     This Joint Proxy Statement and Prospectus ("Proxy Statement") is being

Citizens and First United for use at a special meeting of stockholders of
Citizens to be held on             , 1998, including any adjournments or
postponements of the meeting, and for use at a special meeting of shareholders
of First United to be held on             , 1998, including any adjournments or

stockholders of Citizens.
 
     Stockholders of Citizens will also consider and vote upon the election by
Citizens to be governed by the Arkansas Business Corporation Act of 1987. This
vote will be incidental to the vote on the Merger in that the election will only
be made in order to facilitate compliance with statutory law in consummating the
Merger and no election will be made unless the Merger is approved.

mailed to stockholders of Citizens and stockholders of First United on or about

     Citizens is a corporation organized under the Arkansas Business Corporation
Act of 1965, codified as Ark. Code Ann. sec. 4-26-101 et. seq. (the "1965 Act").
The 1987 Act is applicable to those corporations that were incorporated on or
after January 1, 1988 or those "1965 Act" corporations that elect to be governed
by the 1987 Act by amending their Articles of Incorporation to so state.
 
     The 1965 Act and 1987 Act have statutory merger procedures that must be
complied with in order legally to consummate a merger. Although both Acts
contain similar provisions, Citizens must elect to be governed by the 1987 Act
in order to facilitate compliance with the applicable statutory procedures.
 
THE FIRST UNITED SPECIAL MEETING
 
     Approval of the Merger by the stockholders of First United will be
considered at a Special Meeting to be held at the First National Bank Building,
El Dorado, Arkansas, on             , 1998 at 2:00 p.m. Central Time.
 
     The affirmative vote of the holders of two-thirds of the outstanding shares
of First United Common Stock is required for approval of the Merger.
Stockholders of First United are entitled to dissenters' rights. See "The
Merger -- Right of Dissent Under the 1987 Act."
 
THE CITIZENS SPECIAL MEETING
 
     Approval of the Merger by the stockholders of Citizens will be considered
at a Special Meeting to be held at 200 South Elm Street, Hope, Arkansas 71801 on
            , 1998, at       .m. Central Time.

executive officers and their affiliates hold a total of      % of the
outstanding stock of Citizens as of             , 1997. Stockholders of Citizens
are entitled to dissenters' rights. See "The Merger -- Right of Dissent under
the 1965 Act; Right of Dissent under the 1987 Act."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     It is intended that for federal income tax purposes the Merger will be
treated as a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code"), and, accordingly, for federal
income tax purposes, no gain or loss will be recognized by either First United
or Citizens as a result of the Merger and Citizens' stockholders will not
recognize gain or loss upon the receipt of First United Common Stock in exchange
for Citizens common stock. Citizens expects to receive an opinion of counsel,
dated as of the effective date of the Merger, to the effect that no gain or loss
will be recognized by the Citizens stockholders upon the receipt of First United
Common Stock in exchange for Citizens common stock in connection with the
Merger. The parties to this transaction will not request a ruling from the
Internal Revenue Service concerning the taxability of this transaction. See "The
Merger -- Certain Federal Income Tax Consequences."
 
DISSENTERS' RIGHTS
 
     Holders of First United Common Stock and Citizens common stock are entitled
to dissenters' rights with respect to the Merger. Holders of First United Common
Stock may exercise their right of dissent under the 1987 Act, while holders of
Citizens common stock may exercise their right of dissent under either the 1965
Act or the 1987 Act. See "The Merger -- Right of Dissent under the 1965 Act;
Right of Dissent under the 1987 Act."
 
REGULATORY APPROVALS
 
     The Merger is subject to prior approval by the appropriate banking
regulatory authorities. An application has been filed for approval of the Merger
with the Board of Governors of the Federal Reserve System ("Board") for First
United to acquire Citizens. In conjunction with the Board application, the
Merger is also subject to review by the Department of Justice as to its
competitive effects. An application has also been filed

Merger -- Regulatory Approvals."

accounting purposes. Consummation of the Merger is conditioned upon the receipt

(1) On May 20, 1996, the Board of Directors of First United declared a 3-for-2
    stock split effected in the form of a 50% stock dividend. The dividend was
    distributed on June 28, 1996 to holders of record as of June 7, 1996. All
    per share data have been restated to reflect this stock split.
 
(2) On September 2, 1997, First United acquired by merger, which was made
    effective on September 3, 1997, Fredonia Bancshares, Inc. of Nacogdoches,
    Texas.
 
(3) The Citizens pro forma equivalents represent the respective First
    United/Citizens pro forma combined earnings, dividends and book value per
    common share multiplied by the applicable exchange ratio of 3.1535 shares of
    First United Common Stock for each share of Citizens common stock so that
    the First United/Citizens pro forma equivalent amounts are equated to the
    respective values for one share of Citizens common stock. The exchange ratio
    is determined by dividing First United Common Stock to be received by the
    Citizens stockholders by the 497,860 shares of Citizens common stock
    currently outstanding without reflecting outstanding options to purchase
    Citizens Common Stock.
 
SELECTED FINANCIAL DATA
 
     The table on the following page presents selected historical financial data
of First United and Citizens and selected unaudited pro forma financial data
after giving effect to the Merger as a pooling of interests for accounting
purposes, assuming the Merger had occurred at the beginning of the earliest
period presented, but without giving effect to costs associated with the
consummation of the Merger, which currently are estimated to total $200,000. The
First United historical data for each of the years in the five-year period ended
December 31, 1996 are based on the historical financial statements of First
United as audited by Arthur Andersen LLP, independent public accountants. The
Citizens historical data for each of the years in the five-year period ended
December 31, 1996 is derived from the historical financial statements of
Citizens as audited by Moore Stephens Frost, P.A., independent auditors. The
selected financial data for First United for the nine month periods ended
September 30, 1996 and 1997, and for Citizens for the nine month periods ended
September 30, 1996 and 1997 have been obtained from unaudited financial
statements and, in the opinion of the respective management of First United and
Citizens, include all adjustments necessary to present fairly the data for such
periods. The pro forma data is not necessarily indicative of the results of
operations or the financial condition that would have been reported had the
Merger been in effect during those periods, or as of those dates, or that may be
reported in the future. Pro forma combined per share data of First United and
Citizens give effect to the exchange of each share of Citizens common stock for
3.1535 shares of First United Common Stock.

                                   THE MERGER
 
REASONS FOR THE MERGER
 
     The acquisition of Citizens will expand First United's current markets. The
banking subsidiaries of Citizens are located in Hope, Lewisville, and Texarkana,
Arkansas. Currently, there are no banking offices in the First United system
located in Hope, Lewisville, or Texarkana, Arkansas. Thus, the acquisition of
Citizens expands First United's market into new areas.
 
     Management of First United believes that by expanding its markets, it will
increase the range and competitiveness of its banking services to persons
residing in the Hope, Lewisville, and Texarkana, Arkansas areas while increasing
the earning power of First United.
 
     In reaching its decision to approve the Merger and Merger Agreement,
Citizens' Board consulted with its counsel, as well as with Citizens'
management, and considered a number of factors, including, without limitation,
the following:
 
          a. Citizens' Board's familiarity with and review of Citizens'
     business, operations, earnings and financial condition and future capital
     requirements;
 
          b. Citizens' Board's belief that the terms of the Merger Agreement are
     attractive in that the Merger Agreement allows Citizens stockholders to
     become stockholders in First United, an institution whose
 
                                       13
<PAGE>   21
 
     stock is traded over the NASDAQ Stock Market, and the recent earnings and
     stock performance of First United;
 
          c. First United's wide range of banking products and services and its
     dividend payment history;
 
          d. Citizens' Board's belief, based upon analysis of the anticipated
     financial effects of the Merger, that upon consummation of the Merger,
     First United and its banking subsidiaries would be well capitalized
     institutions, the financial positions of which will be well in excess of
     all applicable regulatory capital requirements;
 
          e. The current and prospective economic and regulatory environment and
     competitive constraints facing the banking industry and financial
     institutions in Citizens' market area;
 
          f. Citizens' Board's belief that, in light of the reasons discussed
     above, First United was the most attractive choice as a long term
     affiliation partner of Citizens; and
 
          g. The expectation that the Merger will generally be a tax-free
     transaction to Citizens and its stockholders.
 
     Citizens' Board did not assign any specific or relative weight to any of
the factors discussed above in their considerations.
 
OPINION OF FINANCIAL ADVISOR
 
     Citizens' Board of Directors retained Hoefer & Arnett to render to the
Board of Directors a written opinion (the "Fairness Opinion") as investment
bankers as to the fairness, from a financial point of view, to the Board of
Directors of Citizens of the terms of the proposed Merger of Citizens with and
into First United, as defined in the Agreement. No limitations were imposed by
Citizens' Board of Directors upon Hoefer & Arnett with respect to the
investigations made or procedures followed in rendering the Fairness Opinion.
 
     A copy of the Fairness Opinion of Hoefer & Arnett, dated as of September
22, 1997, which sets forth certain assumptions made, matters considered and
limits on the review undertaken by Hoefer & Arnett, is attached as Annex IV to
this Proxy Statement. Citizens' shareholders are urged to read the Fairness
Opinion in its entirety. The following summary of the procedures and analysis
performed, and assumptions used by Hoefer & Arnett is qualified in its entirety
by reference to the text of such Fairness Opinion. The Fairness Opinion is
directed to Citizens' Board of Directors only and is directed only to the
financial terms of the transaction and does not constitute a recommendation to
any Citizens shareholder as to how such shareholder should vote at the Special
Meeting.
 
     In arriving at its opinion, Hoefer & Arnett reviewed and analyzed, among
other things, the following: (i) the Agreement; (ii) Annual Reports to
shareholders of Citizens and First United for the years ended December 31, 1995
and December 31, 1996; (iii) quarterly FDIC Call reports for the quarters ended
June 30, 1996, September 30, 1996, December 31, 1996, March 31, 1997 and June
30, 1997; (iv) certain other publicly available financial and other information
concerning Citizens and First United; (v) the historical market prices and
trading activity for the common stock of First United; and (vi) publicly
available information concerning other banks and holding companies, the trading
markets for their securities and the nature and terms of certain other merger
transactions Hoefer & Arnett believes relevant to its inquiry. Hoefer & Arnett
held discussions with senior management of Citizens and First United concerning
their past and current operations, financial condition and prospects, as well as
the results of regulatory examinations.
 
     Hoefer & Arnett reviewed with senior management of First United earnings
projections for 1997 through 2002 for First United as a stand-alone entity,
assuming the Merger does not occur. Hoefer & Arnett reviewed with senior
management of Citizens earnings projections for 1997 through 2002 for Citizens
as a stand-alone entity, assuming the Merger does not occur, prepared by
Citizens. Certain pro forma financial projections for the years 1997 through
2002 for the combined entity were derived by Hoefer & Arnett based partially
upon the information discussed above, as well as Hoefer &Arnett's assessment of
general economic, market and financial conditions.
 
                                       14
<PAGE>   22
 
     In conducting its review and in arriving at its opinion, Hoefer & Arnett
relied upon and assumed the accuracy and completeness of the financial and other
information provided to it or publicly available, and did not attempt to
independently verify the same. Hoefer & Arnett relied upon the management of
Citizens as to the reasonableness of the financial and operating forecasts,
projections (and the assumptions and bases therefor) provided to it, and Hoefer
& Arnett assumed that such forecasts and projections reflect the best currently
available estimates and judgment of the management of Citizens. Hoefer & Arnett
also assumed, without independent verification, that the aggregate allowance for
loan losses for Citizens and First United are adequate to cover such losses.
Hoefer & Arnett did not make or obtain any evaluations or appraisals of the
properties of Citizens or First United, nor did it examine any individual loan
credit files. For purposes of its opinion. Hoefer & Arnett assumed that the
Merger will have the tax, accounting and legal effects described in the
Agreement and relied, as to legal matters, exclusively on counsel to Citizens as
to the accuracy of the disclosures set forth in the Agreement. Hoefer & Arnett's
opinion is limited to the fairness, from a financial point of view, to the
holders of the common stock of Citizens of the terms of the proposed Merger with
First United and does not address Citizens' underlying business decision to
proceed with the Merger.
 
     As more fully discussed below, Hoefer & Arnett considered such financial
and other factors as Hoefer & Arnett deemed appropriate under the circumstances,
including among others the following: (i) the historical and current financial
position and results of operations of Citizens and First United, including
interest income, interest expense, net interest income, net interest margin,
provision for loan losses, non-interest income, non-interest expense, earnings,
dividends, internal capital generation, book value, intangible assets, return on
assets, return on shareholders' equity, capitalization, the amount and type of
non-performing assets, loan losses and the reserve for loan losses, all as set
forth in the financial statements for Citizens and First United; (ii) the assets
and liabilities of Citizens and First United, including the loan, investment and
mortgage portfolios, deposits, other liabilities, historical and current
liability sources and costs and liquidity; and (iii) the nature and terms of
certain other merger transactions involving banks and bank holding companies.
Hoefer & Arnett also took into account its assessment of general economic,
market and financial conditions and its experience in other transactions, as
well as its experience in securities valuation and its knowledge of the banking
industry generally. Hoefer & Arnett's opinion is necessarily based upon
conditions as they existed and can be evaluated on the date of its opinion and
the information made available to it through that date.
 
     In connection with rendering its Fairness Opinion to Citizens' Board of
Directors, Hoefer & Arnett performed certain financial analyses, which are
summarized below. Hoefer & Arnett believes that its analysis must be considered
as a whole and that selecting portions of such analysis and the factors
considered therein, without considering all factors and analysis, could create
an incomplete view of the analysis and the processes underlying Hoefer &
Arnett's Fairness Opinion. The preparation of a fairness opinion is a complex
process involving subjective judgments and it is not necessarily susceptible to
partial analysis or summary description. In its analyses Hoefer & Arnett made
numerous assumptions with respect to industry performance, business and economic
conditions, and other matters, many of which are beyond the control of Citizens.
Any estimates contained in Hoefer & Arnett's analyses are not necessarily
indicative of future results or values, which may be significantly more or less
favorable than such estimates. Estimates of values of companies do not purport
to be appraisals or necessarily reflect the prices at which companies or their
securities may actually be sold. Except as described below, none of the
financial analyses performed by Hoefer & Arnett was assigned a greater
significance by Hoefer & Arnett than any other.
 
     The financial forecasts and projections of Citizens and First United
prepared by Hoefer & Arnett were based on projections provided by the respective
companies as well as Hoefer & Arnett's own assessment of general economic,
market and financial conditions. All such information was reviewed with the
respective managements of Citizens and First United. Citizens and First United
do not publicly disclose internal management financial forecasts and projections
of the type provided to Hoefer & Arnett in connection with its review of the
proposed Merger. Such forecasts and projections were not prepared with a view
towards public disclosure. The forecasts and projections prepared by Hoefer &
Arnett were based on numerous variables and assumptions which are inherently
uncertain, including without limitation, factors related to general economic and
market conditions. Accordingly, actual results could vary significantly from
those set forth in such forecasts and projections.
 
                                       15
<PAGE>   23
 
     In order to determine the fairness of the proposed offer by First United,
Hoefer & Arnett utilized net asset value, market value and investment value
approaches, as explained below.
 
     Net Asset value is the value of the net equity of a bank, including every
kind of property and value. This approach normally assumes liquidation on the
date of appraisal with recognition of securities gains or losses, real estate
appreciation or depreciation and any adjustments to the loan loss reserve,
discounts to the loan portfolio or changes in the net value of other assets. As
such, it is not the best approach to use when valuing a going concern, because
it is based on historical costs and varying accounting methods. Even if the
assets and liabilities are adjusted to reflect prevailing prices and yields
(which is often of limited accuracy because readily available data is often
lacking), it still results in a liquidation value for the concern. Furthermore,
since this method does not take into account the values attributable to the
going concern such as the interrelationship among the company's assets,
liabilities, customer relations, market presence, image and reputation, and
staff expertise and depth, little weight is given to the net asset value method
of valuation.
 
     Market value is defined as the price, established on an "arm's-length"
basis, at which knowledgeable, unrelated buyers and sellers would agree. The
market value is frequently used to determine the price of a minority block of
stock when both the quantity and the quality of the "comparable" data are deemed
sufficient. However, the relative thinness of the specific market for the stock
of the banking company being appraised may result in the need to review
alternative markets of comparative pricing purposes. The "hypothetical" market
value for a small bank with a thin market for its stock is normally determined
by comparison to the average price to earnings, price the equity and dividend
yield of local or regional publicly-traded bank issues, adjusted for lack of
marketability or liquidity.
 
     The market value in connection with the evaluation of control of a bank is
determined by the previous sales of banks in the state or region. In valuing a
business enterprise, when sufficient comparable trade data is available, the
market value deserves greater weighting than the net asset value and equal or
possibly greater weighting than the investment value. In analyzing the fair
market value of Citizens, Hoefer & Arnett has considered the market approach and
has evaluated price to equity and price to earnings multiples of banking
organizations that were sold in Arkansas between January 1, 1996 and September
19, 1997. This data was obtained from SNL Securities, L.P.
 
     Hoefer & Arnett calculated an "Adjusted Book Value" based on June 30, 1997
equity and the price to book value multiples paid for Arkansas banks in 1996 and
1997 at $115.20. Hoefer & Arnett calculated an "Adjusted Earnings Value" based
on Citizens' estimated 1997 earnings and the price to earnings multiples paid
for Arkansas banks in 1996 and 1997 at $121.56. These "Adjusted Book Value" and
"Adjusted Earnings Value" approaches are utilized in supporting the fairness of
the price ($124.56) to be offered for shares of Citizens' Common Stock as
provided for in the Agreement.
 
     Hoefer & Arnett analyzed the value of the aggregate consideration to be
received in the transactions that were announced in 1996 and 1997 in
relationship to the stated book value and earnings as compared to the value of
the aggregate consideration to be received by holders of Citizens' common stock.
 
     Investment value is sometimes referred to as the income value or the
earnings value. The investment value is frequently defined as an estimate of the
present value of future benefits. Another popular investment value method is to
determine the level of the current annual benefits and then capitalize one or
more of the benefit types using an appropriate capitalization rate such as an
earnings or dividend yield. Using a net present value discount rate of 12%, an
acceptable discount rate considering the risk-return relationship most investors
would demand for an investment of this type as of the valuation date, the net
present value of future earnings equaled $72.27.
 
     In order to analyze the reasonableness of the transaction value, the return
on investment is calculated to determine the return that would accrue to a
potential buyer at the transaction value. The return on investment, assuming
sale in year 2000 at the average multiple of book value paid for Arkansas banks,
equaled 8.81% which is lower than what we normally see when evaluating a
controlling interest in a financial institution and, therefore, supports the
fairness of the proposed transaction.
 
                                       16
<PAGE>   24
 
     The transaction value to assets was calculated and compared to the average
purchase price to assets for banking organizations sold in Arkansas in 1996 and
1997. Based on the proposed offer of $124.56 per share (based on the current
market value of First United's stock of $39.50), the price to assets equaled
22.94%, which is above the Arkansas average of 17.05%. Hoefer & Arnett also
calculated the net present value to transaction value, as it has been recognized
that there is a relationship between the net present value of a community
banking organization and the fair market value of a majority block of the
banking organization's stock. The net present value to transaction value ratio
equaled 58.02% which is lower than what we would normally expect and, therefore,
also supports the fairness of the proposed transaction.
 
     Based upon input from senior management of First United and Citizens, as
well as Hoefer & Arnett's own assessment of general economic, market and
financial conditions, and all financial and other factors it deemed appropriate
under the circumstances, Hoefer & Arnett prepared financial projections for
First United and Citizens on a stand alone basis. The projections were based on
numerous variables and assumptions which are inherently uncertain, and
accordingly, actual results could vary from those set forth in such projections.
 
     First United is projected to generate a return on average assets of 1.29%
gradually increasing to 1.50% in the years 1997 through 2002. First United's
assets are projected to increase by 3.53% in 1997 and 5.00% in 1998 through
2002. (The projections for First United include the acquisitions of Fredonia
Bancshares, Inc., Nacogdoches, Texas, and City Bank & Trust, Shreveport,
Louisiana.) Citizens is projected to generate a return on average assets of
1.30% in 1997, 1.40% in 1998 through 2002. Citizens' assets are projected to
increase by 5.08% in 1997 and 4.00% in 1998 through 2002.
 
     Proforma financial projections for the combined entity were derived by
Hoefer & Arnett based upon the projections discussed above. Hoefer & Arnett
analyzed the book value and earnings per share impact of the proposed
transaction on Citizens' shareholders over the next five years. At an exchange
ratio of 3.1535 shares of First United's Common Stock for each share of
Citizens' common stock, Citizens shareholders are projected to experience equity
per share appreciation ranging from 3.53% to 5.75% in the years 1998 through
2002. On an earnings per share basis, Citizens shareholders are projected to
experience appreciation ranging from 3.44% to 18.79% in the years 1998 through
2002.
 
     For services rendered in connection with the Merger, Citizens has paid
Hoefer & Arnett a fee of $17,000 and agreed to reimburse Hoefer & Arnett for all
reasonable expenses incurred in connection with its services. Citizens has also
agreed to indemnify Hoefer & Arnett against certain liabilities relating to or
arising out of its engagement, including liabilities under securities laws.
 
THE AGREEMENT
 
     The following description of certain features of the Agreement is qualified
in its entirety by the full text of the Agreement, which is incorporated herein
by reference and attached hereto by Annex I.
 
     Under the terms of the Agreement, Citizens will be merged with and into
First United. As part of the Merger, the Agreement provides that the
stockholders of Citizens will receive total consideration consisting of one
million five hundred seventy thousand (1,570,000) shares of fully paid and
nonassessable shares of Common Stock, $1.00 par value of First United ("Purchase
Price"). All of the issued and outstanding shares of Citizens common stock,
other than shares of Citizens common stock held by dissenting stockholders,
shall be converted into the right to receive the Purchase Price based upon each
Citizens stockholder's pro rata ownership of the total number of issued and
outstanding shares of Citizens common stock at the effective time of the Merger.
Fractional shares of First United Common Stock shall not be issued. Any Citizens
shareholder entitled to receive a fractional share shall receive a cash payment
in lieu thereof equal to the value of the fractional share based on the average
price of First United Common Stock common stock. The average price of First
United Common Stock is defined as the average sales price per share for all
trades occurring during the period of ten (10) trading days on which one or more
trades actually takes place and which ends immediately prior to the second
trading day preceding the closing date.
 
                                       17
<PAGE>   25
 
     In addition, either party may terminate the Agreement, if the Merger is not
closed on or before March 31, 1998 provided that the failure to close is not
caused by a breach of the Agreement by the party seeking to terminate it.
 
     Citizens has agreed, for the period prior to the consummation of the
Merger, to operate its businesses only in the usual, regular and ordinary
course. In addition, Citizens will use reasonable efforts to maintain and keep
its properties in as good repair and condition as at present, except for
ordinary wear and tear and to perform all obligations required under all
material contracts, leases, and documents relating to or affecting their
respective assets prior to the consummation of the Merger. Citizens has further
agreed that, prior to consummation of the Merger, it will not incur any material
liabilities or obligations, except in the ordinary course of business, or take
any action which would or is reasonably likely to adversely affect the ability
of either First United or Citizens to obtain any necessary approvals, adversely
affect the ability of First United or Citizens to perform their covenants and
agreements under the Agreement, or result in any of the conditions to the Merger
not being satisfied. Citizens has further agreed that, unless otherwise required
by applicable law, it shall not initiate, solicit or encourage any inquiry or
proposal which constitutes a competing transaction.
 
     The Agreement requires that certain conditions occur or be waived prior to
the closing date ("conditions precedent"), including (a) approval by Citizens
and First United stockholders by two-thirds of all outstanding shares,
respectively; (b) approval by the appropriate bank regulatory authorities; (c)
receipt by Citizens of letter from Hoefer & Arnett dated on or before the
Closing Date stating that in such financial advisor's opinion to the Board of
Directors of Citizens that the consideration to be paid in the merger is fair to
the Citizens shareholders from a financial point of view; (d) receipt by First
United of an opinion from Arthur Andersen LLP that the Merger will qualify for
pooling of interests treatment under the applicable accounting principles; and
(e) satisfaction of other normal conditions to closing a merger transaction. It
is also a condition to the Merger that First United have an effective
registration statement on file with the Securities and Exchange Commission
covering the issuance of shares to be exchanged pursuant to the Merger. Prior to
the effective date of the Merger, any condition of the Agreement, except those
required by law, may be waived by the party benefitted by the condition.
 
     The effective date of the Merger will be the date the Articles of Merger
are filed with the Arkansas Secretary of State, or the date so stated in the
Articles of Merger. The Agreement provides that a closing date will be set by
mutual agreement to occur within a reasonable time following the date on which
the last of all regulatory and other approvals necessary to consummate the
Merger have been received and all necessary time periods imposed by regulatory
authorities have elapsed. The parties may, however, amend the Agreement to
provide a later closing date.
 
REGULATORY APPROVALS
 
     The Merger is subject to prior approval by the appropriate banking
regulatory authorities. An application has been filed for approval of the Merger
with the Board of Governors of the Federal Reserve System ("Board") for First
United to acquire Citizens. In conjunction with the Board application, the
Merger is also subject to review by the Department of Justice as to its
competitive effects. An application has also been filed with the Arkansas State
Bank Department for approval of the Merger.
 
ANTITRUST MATTERS
 
     The Department of Justice has fifteen (15) calendar days after approval by
the Board in which to challenge the proposed Merger on anti-trust
considerations. The approval letter or Order from the Board, therefore will
provide that the Merger may not be consummated until fifteen (15) calendar days
after the effective date of such letter or Order. The letter or Order will also
provide that the transaction must be consummated no later than ninety (90)

FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a discussion of certain material federal income tax
considerations in connection with the Merger and of the tax opinion of Friday,
Eldredge & Clark, special tax counsel to Citizens. This discussion does not
address all aspects of federal income taxation that may be relevant to
particular stockholders of Citizens and may not be applicable to stockholders
who are not citizens or residents of the United States, or who may acquire First
United Common Stock pursuant to the exercise or termination of employee stock
options or otherwise as compensation, nor does the discussion address the effect
of any applicable foreign, state, local or other tax laws. This discussion
assumes that the Citizens stockholders hold their Citizens common stock as
capital assets within the meaning of Section 1221 of the Internal Revenue Code
of 1986, as amended (the "Code"). EACH CITIZENS STOCKHOLDER SHOULD CONSULT HIS
OR HER OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO HIM OR HER OF
THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL AND
OTHER TAX LAWS.
 
     The Merger will qualify as a tax-free corporate reorganization for federal
income tax purposes under Section 368(a)(1)(A) of the Code, if it satisfies the
specific requirements of the Code, the regulations promulgated thereunder, and
pertinent judicial decisions. The most important of these requirements are (i)
the transaction must qualify as a merger under applicable state or federal law
and (ii) the stockholders of Citizens must maintain a "continuity of interest"
in the surviving corporation after the Merger. The Internal Revenue Service
takes the position that this "continuity of interest" test will be satisfied if
the former Citizens stockholders receive, in the Merger, a number of shares of
common stock of First United having a value, as of the Effective Date (as
defined herein), equal to at least fifty percent (50%) of the value of all the
outstanding stock of Citizens as of such date, and acquire such stock without a
present intent to sell, transfer or otherwise dispose of such stock in a manner
that would cause the fifty percent (50%) continuity of interest threshold to be
violated. In general, this requires the stockholders of Citizens to collectively
surrender at least 50% of their Citizens common stock in exchange for First
United Common Stock in the Merger, without a present intent to sell, transfer or
otherwise dispose of such stock in violation of the fifty percent (50%)
continuity of interest requirement.
 
     The Merger has been structured in a manner to qualify as a statutory merger
under the law of the State of Arkansas. In addition, it is expected that the
stockholders of Citizens will collectively exchange a sufficient number of
shares of Citizens common stock for First United Common Stock so that the 50%
"continuity of interest" test initially should be satisfied in connection with
the Merger.
 
     Accordingly, assuming these tests are satisfied, and provided other
specific requirements contained in the Code, the regulations promulgated
thereunder, and pertinent judicial decisions are met, the transaction should
qualify as a tax-free corporate reorganization for federal income tax purposes
pursuant to the provisions of Section 368(a)(1)(A) of the Code.
 
     If the Merger qualifies as a tax-free corporate reorganization, the
material federal income tax consequences of the Merger will be as follows: (i)
no material gain or loss will be recognized by Citizens or First United as a
result of the Merger; (ii) no gain or loss will be recognized by the
stockholders of Citizens upon the receipt of First United Common Stock received
solely in exchange for their shares of Citizens common stock in connection with
the Merger; (iii) the tax basis of the shares of First United Common Stock
received by the stockholders of Citizens in the Merger will, in each instance,
be the same as the basis of the shares of Citizens common stock surrendered in
exchange therefor; (iv) the holding period of the shares of First United Common
Stock received by the stockholders of Citizens in the Merger will, in each
instance, include the holding period of the shares of Citizens common stock
exchanged therefor, provided that the shares of Citizens common stock were held
as capital assets on the date of the Merger; and (v) the payment of cash to
stockholders of Citizens in lieu of fractional shares of First United Common
Stock will be a taxable transaction and will be treated as if the fractional
shares were distributed as part of the exchange and then redeemed by First
United for cash, and any such cash payments will be treated as having been
received by the stockholder as a distribution in redemption of the fractional
share interest, subject to the provisions of Section 302 of the Code.
 
                                       19
<PAGE>   27
 
     Stockholders of Citizens who exercise dissenters' rights and receive cash
for their shares of Citizens common stock will have engaged in a taxable
transaction and will be treated as having received such cash as a distribution
in redemption of such stockholders' Citizens common stock, subject to the
conditions and limitations of Section 302 of the Code.
 
     If the Merger does not qualify as a tax-free corporate reorganization for
federal income tax purposes, it will constitute a taxable transaction to the
stockholders of Citizens. In such circumstances, gain or loss will be recognized
by the stockholders of Citizens to the extent of the difference between the fair
market value, on the Effective Date, of the shares of First United Common Stock
received in connection with the Merger, and the adjusted basis of the shares of
Citizens common stock surrendered in the transaction. The fair market value of
the First United Common Stock on the Effective Date may be determined on the
basis of the average high and low selling prices of such stock on the day of the
transaction. If the transaction is taxable, the holding period for the shares of
First United Common Stock to be received by the stockholders of Citizens will
commence on the day following the date of the transaction.
 
     Because the tax consequences to any particular stockholder may be affected
by matters not pertaining to the Merger, it is recommended that each stockholder
of Citizens consult his or her own personal tax advisor concerning the specific
income tax consequences of the Merger, including the applicability and effect of
foreign, state, local and other tax laws.
 
ACCOUNTING TREATMENT
 
     First United intends to treat the merger as a pooling-of-interests for
accounting purposes. Consequently, in accordance with generally accepted
accounting principles, First United anticipates that it will restate its 1997
and prior consolidated financial statements to include the assets, liabilities,
stockholders' equity and results of operations of Citizens as reflected in its
consolidated financial statements, subject to appropriate adjustments, if any,
to conform accounting principles of the two companies.
 
RIGHT OF DISSENT UNDER THE 1965 ACT
 
     HOLDERS OF CITIZENS COMMON STOCK WILL BE ENTITLED TO EXERCISE DISSENTER'S
RIGHTS EITHER UNDER THE 1965 ACT OR THE 1987 ACT. IF APPROVED, THE ELECTION TO
BE GOVERNED BY THE 1987 ACT BY THE STOCKHOLDERS OF CITIZENS, AS DISCUSSED BELOW,
WILL BE MADE PRIOR TO CONSUMMATION OF THE MERGER BUT SUBSEQUENT TO A VOTE ON
SUCH MERGER. THEREFORE, FIRST UNITED WILL RECOGNIZE COMPLIANCE WITH EITHER THE
1965 ACT OR THE 1987 ACT AS A VALID EXERCISE OF DISSENTER'S RIGHTS WITH RESPECT
TO SUCH MERGER. FOR A DISCUSSION OF THE PROCEDURE TO BE FOLLOWED UNDER THE 1987
ACT, SEE "THE MERGER -- RIGHT OF DISSENT UNDER THE 1987 ACT."
 
     Under Arkansas law, holders of Citizens common stock are entitled to
dissenters' rights pursuant to Ark. Code Ann. sec.4-26-1007 of the 1965 Act.
However, if a holder of shares of Citizens common stock chooses to follow the
procedure under the 1965 Act, he shall only be entitled to such rights if he
complies with that statute. The following summary does not purport to be a
complete statement of the method of compliance with Section 4-26-1007 and is
qualified by reference to those statutory sections which are attached hereto by
Annex.
 
     A holder of Citizens stock who wishes to perfect his dissenter's rights in
the event that the Merger is adopted must:
 
          (a) File with the corporation, prior to or at the meeting of
     stockholders at which the vote on the Agreement is to be made, written
     objection to the Agreement; and
 
          (b) Not have voted in favor of the Agreement.
 
     Any written notice of objection to the Agreement pursuant to clause (a) of
the immediately proceeding paragraph should be mailed or delivered to Citizens
National Bancshares of Hope, Inc., 200 South Elm
 
                                       20
<PAGE>   28
 
Street, Hope, Arkansas 71801, Attention: Dennis Ramsey, Secretary. Because the
written objection must be delivered prior to or at the stockholder vote on the
Agreement, it is recommended, although not required, that a stockholder using
the mail should use certified or registered mail, return receipt requested, to
confirm that he has made timely delivery.
 
     Within ten (10) days after the consummation of the Merger, any stockholder
objecting to the Merger must make a written demand on First United for payment
of the fair value of his shares as of the day before the vote on the Agreement
was taken. This second notice should be mailed to First United Bancshares, Inc.,
Main and Washington Streets, El Dorado, Arkansas, 71730, Attention: John E.
Burns, Vice President and Chief Financial Officer. The demand must state the
number and class of shares owned. If a demand is not made within the 10-day
period, the stockholder is bound by the Agreement.
 
     Within ten (10) days after the Merger is effected, First United shall give
notice to each dissenting stockholder who made demand as provided above for the
payment of the value of his shares. If the dissenting stockholder and First
United agree upon the value of the shares within thirty (30) days after the date
of the Merger, then payment shall be made within ninety (90) days of the Merger.
Simultaneously with the payment, the dissenting stockholder shall surrender the
certificates representing his shares.
 
     If within the thirty-day period no agreement is reached as to the value of
the dissenting stockholder's shares, the dissenting stockholder must file a
petition in Pulaski County Circuit Court within 60 days after the expiration of
the 30-day period asking for a determination of the fair value of his shares.
The judgment will be final and is payable only upon and simultaneously with the
surrender of the certificates representing the shares to First United. If a
dissenting stockholder fails to file a petition within the 60-day period, he and
all persons claiming under him shall be bound by the terms of the Agreement.
 
RIGHT OF DISSENT UNDER THE 1987 ACT
 
     HOLDERS OF FIRST UNITED COMMON STOCK OR CITIZENS COMMON STOCK SHALL BE
ENTITLED TO DISSENTER'S RIGHTS PURSUANT TO ARK. CODE ANN. SEC.4-27-1301 ET. SEQ.
OF THE 1987 ACT WITH RESPECT TO THE MERGER. HOWEVER, A HOLDER OF FIRST UNITED
COMMON STOCK SHALL ONLY BE ENTITLED TO EXERCISE DISSENTER'S RIGHTS UNDER THE
1987 ACT, WHEREAS A HOLDER OF CITIZENS COMMON STOCK MAY ALSO EXERCISE SUCH
RIGHTS UNDER THE 1965 ACT. SEE "THE MERGER -- RIGHT OF DISSENT UNDER THE 1965
ACT."
 
     The following summary does not purport to be a complete statement of the
method of compliance with the 1987 Act and is qualified by reference to those
statutory sections which are attached hereto as Annex II.
 
     A holder of First United Common Stock who wishes to perfect his dissenter's
rights in the event that the Merger is adopted must:
 
          (a) File with the corporation, prior to or at the meeting of
     stockholders at which the vote on the Agreement is to be made, written
     objection to the Agreement; and
 
          (b) Not have voted in favor of the Agreement.
 
     Any written notice of objection to the Agreement pursuant to clause (a) of
the immediately preceding paragraph should be mailed or delivered by a Citizens
stockholder to Citizens National Bancshares of Hope, Inc., 200 South Elm Street,
Hope, Arkansas, 71801, Attention: Dennis Ramsey, Secretary, or by a stockholder
of First United, to First United Bancshares, Inc., Main and Washington Streets,
El Dorado, Arkansas, 71730, Attention: John Burns, Vice President and Chief
Financial Officer. Because the written objection must be delivered prior to or
at the time of the stockholder votes on the Merger, it is recommended, although
not required, that a stockholder using the mail should use certified or
registered mail, return receipt requested, to confirm that he has made timely
delivery.
 
     If the Merger is adopted at the special stockholders meeting, the
corporation must send to the dissenting stockholder, no later than ten (10) days
after the corporate action was taken, a dissenter's notice which will
 
                                       21
<PAGE>   29
 
inform the stockholder where a demand for payment must be sent, where the
stockholder's share certificates must be deposited and provide a form for
demanding payment. The dissenter's notice will also notify the stockholder of a
time period of not fewer than thirty (30) nor more than sixty (60) days within
which the stockholder must deliver the payment demand form and stock
certificates to the corporation.
 
     As soon as the Merger is consummated, or upon receipt of a payment demand
by the dissenting stockholder, First United must pay the dissenting stockholder
the amount First United estimates to be the fair value of the shares, plus
accrued interest and deliver to the dissenting stockholder the corporation's
balance sheet as of the most recent fiscal year, an income statement for that
year, a statement of changes in stockholder equity for that year, and the latest
available interim financial statement. At this time, First United shall also
deliver to the dissenting stockholder a statement of the corporation's estimate
of fair value of the shares, an explanation of how interest was calculated, a
statement of the dissenter's right to demand a higher value for his shares and a
copy of the appropriate statutory provisions governing the dissenters rights
procedure.
 
     Within thirty (30) days after the dissenting stockholder has received
payment in the amount the corporation estimates to be the fair value of the
shares, the dissenting stockholder must notify the corporation, in writing, of
his own estimate of fair value. If the dissenting stockholder does not notify
the corporation within this thirty (30) day period, he waives his right to
demand a higher payment.
 
     If the demand for payment, as referenced in the immediately preceding
paragraph remains unsettled for sixty (60) days from the date the corporation
receives the dissenting stockholder's demand for payment, the corporation must
commence a proceeding and file a petition in Pulaski County Circuit Court to
determine the fair value of the shares and the amount of accrued interest to be
paid.
 
EXCHANGE RATIO FOR THE MERGER
 
     The Agreement between First United and Citizens provides that the
stockholders of Citizens will receive total consideration consisting of one
million five hundred seventy thousand (1,570,000) shares of fully paid and
nonassessable shares of Common Stock, $1.00 par value of First United ("Purchase
Price"). All of the issued and outstanding shares of Citizens common stock and
all outstanding options to acquire Citizens common stock, other than shares of
Citizens common stock held by dissenting stockholders, shall be converted into
the right to receive a pro rata portion of the Purchase Price based upon each
Citizens stockholder's pro rata ownership of the total number of issued and
outstanding shares of Citizens common stock at the effective time of the Merger.
Fractional shares of First United Common Stock shall not be issued. Any Citizens
shareholder entitled to receive a fractional share shall receive a cash payment
in lieu thereof equal to the value of the fractional share based on the average
sales price per share of First United Common Stock. The average price of First
United Common Stock is defined as the average sales price per share for all
trades occurring during the period of ten (10) trading days on which one or more
trades actually takes place and which ends immediately prior to the second
trading day preceding the closing date ("Average Price"). The following table
illustrates a range of average sales prices for First United Common Stock and
based upon these average prices, calculates the purchase price, and the value
received by Citizens shareholders. The actual Average Price at the effective
time of the Merger may be higher or lower than the per share examples used
below. THIS TABLE IS FOR ILLUSTRATION PURPOSES ONLY AND SHOULD NOT BE RELIED
UPON AS THE ACTUAL AVERAGE PRICE, ACTUAL EXCHANGE RATIOS, OR THE ACTUAL AMOUNT
OF CONSIDERATION TO BE EXCHANGED.

              ELECTION BY CITIZENS STOCKHOLDERS UNDER THE 1987 ACT
 
ELECTION INCIDENTAL TO THE MERGER
 
     THE ELECTION BY THE STOCKHOLDERS OF CITIZENS TO BE GOVERNED BY THE ARKANSAS
BUSINESS CORPORATION ACT OF 1987 IS INCIDENTAL TO THE MERGER PROPOSAL AND
APPROVAL OF SUCH ELECTION WILL HAVE NO FORCE OR EFFECT UNLESS THE MERGER IS
LIKEWISE APPROVED.
 
REASON FOR THE ELECTION
 
     Citizens is a corporation that was organized under the Arkansas Business
Corporation Act of 1965, codified at Ark. Code Ann. sec.4-26-101 et. seq. The
1987 Act is applicable to those corporations that were incorporated on or after
January 1, 1988 or those "1965 Act" corporations that elect to be governed by
the 1987 Act by amending their Articles of Incorporation to so state.
 
     The 1965 Act and 1987 Act have statutory merger procedures that must be
complied with in order legally to consummate a merger. Although both acts
contain similar provisions, it is advisable for Citizens to elect to be governed
by the 1987 Act in order to facilitate compliance with the applicable statutory
requirements.
 
RESULT OF THE ELECTION
 
     The affirmative vote of two-thirds of all outstanding shares of Citizens
common stock will authorize Citizens to amend its Articles of Incorporation and
thereby elect to be governed by the 1987 Act. First United is governed by the
1987 Act and shares of First United Common Stock received by Citizens
stockholders upon consummation of the Merger will entitle such stockholders
rights under the 1987 Act. The following discussion is an analysis of the
material differences between the 1965 and 1987 Act with respect to Stockholders'
rights.
 
     Powers of Directors in Setting Preferences, Rights and Limitation of
Classes and Series of Stocks. The 1965 Act states that the preferences, rights
and limitations of classes of stock must be specified in the Articles, and that
the power to establish certain limited rights and preferences for series may be
delegated to the Board. The 1987 Act, however, allows inclusion of a provision
in the Articles which gives the Board the power to set the preferences, rights
and limitations of any class or series of stock before any shares of the class
or series are issued. This power is exercised by filing with the Secretary of
State Articles of Amendment, adopted without stockholder action.
 
     Preemptive Rights. The 1987 Act denies stockholders preemptive rights
(i.e., the right of existing stockholders to acquire newly-issued shares of
stock on a pro rata basis of current ownership interest) unless the Articles
specifically authorize preemptive rights. In contrast, the 1965 Act grants
certain preemptive rights unless denied by the Articles.
 
     Restrictions On Distributions. The 1987 Act allows a corporation to elect
in its Articles to restrict its ability to make distributions. The 1965 Act has
no such provision.
 
     Quorum. The 1987 Act, like the 1965 Act, provides that a quorum, for
purposes of a stockholders meeting, will be a majority of the shares entitled to
vote unless the Articles provide otherwise. The 1987 Act does not provide a
minimum size for the quorum. The 1965 Act provides that a quorum may not be less
than one-third of the shares entitled to vote.
 
     Cumulative Voting. Cumulative voting is a method of voting for directors
where each share entitled to vote is given as many votes as there are board
positions being voted on; the votes may be "cumulated," or cast for a single
position, rather than spread among the available positions. The 1987 Act does
not allow stockholders to cumulate their votes for election of directors unless
the Articles of Incorporation so provide. This is contrary to the 1965 Act,
which grants stockholders absolute cumulative voting rights.
 
                                       31
<PAGE>   39
 
     Removal of Directors. The 1987 Act allows the Articles to provide that
directors may be removed only for cause. The 1965 Act does not allow such a
limitation and provides that directors may be removed with or without cause by a
majority of the shares entitled to vote.
 
     Vacancy on Board of Directors. The 1987 Act provides that unless the
Articles provide otherwise, any vacancy on the board may be filled by either the
stockholders or the remaining directors. This is a change from the 1965 Act,
under which the remaining directors fill vacancies unless the Articles provide
otherwise.
 
     Amendment of By-Laws. The 1987 Act provides that the Articles may reserve
to the stockholders the power to amend a corporation's by-laws. If the power is
not so reserved, the board may amend the by-laws, but stockholders may not be
excluded from the power to amend the by-laws. The 1965 Act provides that the
board of directors alone have the power to amend the by-laws, unless the
Articles reserve that power solely to the stockholders.
 
     By-Law Increasing Quorum or Voting Requirements for Stockholders. The 1987
Act allows the stockholders to adopt a by-law that fixes a greater stockholder
quorum or voting requirement than the statutory requirement if such by-law is
authorized by the Articles of Incorporation. The 1965 Act has no such provision.
 
     Voting to Adopt Merger. The 1987 Act allows the Articles to set a voting
requirement for mergers which is greater than the statutory requirement of a
majority of votes to be cast. The 1965 Act includes a statutory requirement of
two-thirds of the votes entitled to be cast to approve a merger.
 
     Sales of Assets in Regular Course of Business and Mortgage of
Assets. Unless otherwise provided in the Articles, the 1987 Act allows the board
to act without stockholder approval in the sale or other disposition of all, or
substantially all, of the property of the corporation in the usual course of
business and to mortgage all or any of the corporation's property, whether or
not in the usual course of business. However, the 1965 Act contains the same
provision.
 
     Notice of Stockholder Meetings. The 1987 Act requires notice of the date,
time, and place of each annual or special meeting of the stockholders. If the
meeting is to consider a proposal to increase the authorized capital stock or
bonded indebtedness of the corporation, the notice must be given no fewer than
75 days before the meeting period. The 1965 Act has the same provision. Under
the 1987 Act, in all other cases the notice must be given no fewer than 10 and
no more than 60 days before the meeting date. Under the 1965 Act notice cannot
be given fewer than 10 and more than 50 days prior to the meeting.
 
     Proxies. Like the 1965 Act, the 1987 Act allows a stockholder to vote by
proxy. The procedural provisions for the exercise of proxies under the 1987 Act
are the same as under the 1965 Act.
 
     Voting. The 1987 Act, unlike the 1965 Act, does not count abstaining votes
in determining whether there are sufficient affirmative votes to approve a
measure. The 1965 Act states that (unless a greater number is required by
statute or by the Articles) approval by stockholders takes the affirmative vote
of a majority of the shares represented at the meeting and entitled to vote on
the subject matter. The 1987 Act, however, provides that the action is approved
if the votes cast within the voting group favoring the action exceed the votes
cast opposing the action.
 
     Dissenting Stockholders. Those transactions giving rise to dissenters'
rights under the 1965 Act are as follows:
 
          1. Consummation of a sale of all or substantially all of the assets of
     a corporation otherwise than in the usual or ordinary course of its
     business.
 
          2. Consummation of a merger or consolidation to which the corporation
     is a party unless on the date the Articles of Merger are filed the
     surviving corporation wholly owns the other corporations that are parties
     to the Merger.
 
                                       32
<PAGE>   40
 
     Under the 1987 Act, a stockholder is entitled to dissent from the following
corporate actions:
 
          1. Consummation of a plan of merger to which the corporation is a
     party if stockholder approval is required or if the corporation is a
     subsidiary that is merged with its parent;
 
          2. Consummation of a plan of share exchange to which the corporation
     is a party and which requires stockholder approval;
 
          3. Consummation of a sale or exchange of all, or substantially all, of
     the property of the corporation other than in the usual and regular course
     of business if stockholder approval is required;
 
          4. An amendment of the Articles of Incorporation that materially and
     adversely affects the rights of dissenters' shares; or
 
          5. Any other corporate action taken pursuant to a stockholder vote to
     the extent the Articles of Incorporation, the By-Laws, or a resolution of
     the board of directors provides that stockholders are entitled to dissent.
 
     For a summary of the procedure that would be followed in order to exercise
dissenters' rights under the 1965 Act, See "The Merger -- Right of Dissent under
the 1965 Act." For a summary of the procedure that would be followed in order to
exercise dissenters' rights under the 1987 Act, See "The Merger -- Right of
Dissent under the 1987 Act."
 
                         FIRST UNITED BANCSHARES, INC.
 
GENERAL
 
     First United is a multi-bank holding company incorporated in 1980 for the
purpose of holding all of the outstanding stock of The First National Bank of El
Dorado, El Dorado, Arkansas. Between 1981 and 1997, First United acquired twelve
other banks in different cities within Arkansas, Louisiana and Texas. The banks
acquired were the First National Bank of Magnolia, Magnolia, Arkansas; Merchants
and Planters Bank, N.A. of Camden, Camden, Arkansas; City National Bank of Fort
Smith, Fort Smith, Arkansas; Commercial Bank at Alma, Alma, Arkansas; The Bank
of North Arkansas, Melbourne, Arkansas; First United Bank, Stuttgart, Arkansas;
FirstBank, Texarkana, Texas; Citizens Bank & Trust, Carlisle Arkansas; Hazen
First State Bank, Hazen, Arkansas; First Bank of Arkansas, Brinkley, Arkansas;
City Bank & Trust of Shreveport, Shreveport, Louisiana; and Fredonia State Bank,
Nacogdoches, Texas. On May 16, 1997, the Carlisle, Hazen and Brinkley banks were
merged with and into First United Bank. Each of the banks are wholly-owned by
First United, and, furthermore, are banks organized under the laws of the United
States, Arkansas, Texas, or Louisiana and are regulated by the Office of the
Comptroller of the Currency, the Federal Reserve System, the Arkansas Bank
Department, the Texas Department of Banking, or the Louisiana Office of
Financial Institutions. As of September 30, 1997, First United, on a
consolidated basis, had a total of $931,545,000 of loans outstanding, an
allowance for loan losses of $13,491,000, total deposits of $1,565,185,000 and
total stockholders' equity of $184,950,000. In 1996 First United Trust Company
was chartered as a wholly-owned subsidiary of First United to handle and expand
trust business formerly done by First United's subsidiary banks.
 
     The banks offer customary services of banks of similar size and similar
markets, including interest-bearing and non-interest-bearing deposit accounts,
commercial, real estate and personal loans, trust services, correspondent
banking services and safe deposit box activities.
 
     The banking business is highly competitive. The subsidiary banks of First
United compete actively with national and state banks, savings and loan
associations, securities dealers, mortgage bankers, finance companies and
insurance companies.

     First Republic Bancshares, Inc. On December 9, 1997 First United and First
Republic Bancshares, Inc., a bank holding company headquartered in Rayville,
Louisiana ("Republic") entered into an Agreement and Plan of Reorganization that
calls for First United to acquire for shares of First United's Common Stock all
of the issued and outstanding shares of Republic and its wholly-owned bank
subsidiary, First Republic Bank, Rayville, Louisiana. At September 30, 1997
Republic had consolidated assets of approximately $148.9 million and
shareholders' equity of approximately $11.53 million. Upon consummation of the
transaction First Republic Bank would become a wholly-owned subsidiary of First
United. The total number of shares of First United Common Stock to be issued in
the transaction would be 800,000 shares, which represents approximately 6.75
percent of the total number of shares of First United outstanding as of the date
hereof. The Republic acquisition, which is subject to shareholder and regulatory
approvals, is expected to be completed in the first or second quarter of 1998.
There can be no assurance that the transaction will be consummated. Consummation
of the Merger is not conditioned upon consummation of the Republic acquisition.
 
REGULATION
 
     First United is a registered bank holding company pursuant to the Bank
Holding Company Act of 1956, as amended (the "Act"), and as such, is subject to
regulation and examination by the Federal Reserve Board and is required to file
with the Federal Reserve Board annual reports and other information regarding
the business operations of itself and its subsidiaries. The Act provides that a
bank holding company may be required to obtain Federal Reserve Board approval
for the acquisition of more than 5% of the voting securities of substantially
all of the assets of any bank or bank holding company, unless it already owns a
majority of the voting securities of such bank or bank holding company. The Act
prohibits First United from engaging in any business other than banking or
bank-related activities specifically allowed by the Federal Reserve Board. The
Act also prohibits First United and its subsidiaries from engaging in certain
tie-in arrangements in connection with the extension of credit, the lease of
sale of property or the provision of any services.
 
     As a registered bank holding company, First United is subject to the
Federal Reserve Board's position that a bank holding company should serve as a
"source of strength" for its bank subsidiaries. In an early appreciation of the
doctrine the Federal Reserve Board announced that failure to assist a troubled
bank subsidiary when its holding company was in a position to do so was an
unsafe and unsound practice and the Federal Reserve Board claimed the authority
to order a bank holding company to capitalize its subsidiary banks.
 
     In 1991, Congress modified the source of strength doctrine by creating a
system of prompt corrective actions under which the federal banking agencies are
required to take certain actions to resolve the problems of depository
institutions based on their level of capitalization. In a bank holding company
organization, an undercapitalized insured depository institution must submit a
capital restoration plan to the appropriate agency which may not accept the plan
unless the company controlling the institution has guaranteed that the
institution will comply with the plan until the institution has been adequately
capitalized on average during each of four consecutive calendar quarters. The
aggregate liability to the guaranteeing companies is the lesser of an amount
equal to 5 percent of the institution's total assets at the time the institution
became undercapitalized, or the amount which is necessary to bring the
institution into compliance with applicable capital standards.
 
     For a significantly undercapitalized institution, the appropriate agency
must prohibit a bank holding company from making any capital distribution
without prior Federal Reserve Board approval. The agency also may require a bank
holding company to divest or liquidate the institution.
 
     First United and its subsidiaries are subject to various federal banking
laws including the Financial Institutions, Reform, Recovery and Enforcement Act
of 1989 ("FIRREA") which, among other things, made substantive changes to the
deposit insurance system. As a part of the reorganization of the deposit
insurance funds, the deposit premiums for insurance of Bank Insurance Fund
members were significantly increased. FIRREA also authorized bank holding
companies to acquire savings and thrift institutions without tandem operation
restrictions. Furthermore, FIRREA expanded the authority of regulatory agencies
to assess severe
 
                                       34
<PAGE>   42
 
penalties ranging from $5,000 per day to $1,000,000 per day, on persons or
institutions that the agency finds in violation of a broad range of activities.
 
     First United and its subsidiaries are also subject to the provisions of the
Federal Deposit Insurance Corporation Improvement Act of 1991, which provided
for industry-wide standards in such areas as real estate lending, further
restrictions on brokered deposits and insider lending, establishment of a
risk-based deposit insurance system, enhanced examinations and audits of banking
institutions, the adoption of a Truth-in-Savings Act, various
merger-and-acquisitions related provisions, and the implementation of
legislation on foreign bank operations in the United States.
 
     The provisions of the Community Reinvestment Act of 1977, as amended, are
applicable to the subsidiaries of First United. Federal Regulators are required
to consider performance under the Community Reinvestment Act before approving an
application to establish a branch or acquire another financial institution. The
Federal Reserve Board has promulgated regulations governing compliance with the
Community Reinvestment Act in Regulation BB. Recent regulatory and statutory
developments show that compliance with the Community Reinvestment Act is subject
to strict scrutiny and is often grounds for denial of an application to federal
regulators. First United's subsidiary banks are all rated "satisfactory" for CRA
purposes.
 
     On January 19, 1989, the Federal Reserve Board issued final guidelines to
implement risk-based capital requirements for bank holding companies. The
guidelines establish a systematic analytical framework that makes regulatory
capital requirements more sensitive to differences in risk profiles among
banking organizations, takes off-balance sheet exposures into account in
assessing capital adequacy, and minimizes disincentives to holding liquid,
low-risk assets. The guidelines provided for phasing in risk-basked capital
standards through the end of 1992, at which time the standards became fully
effective. First United's year end 1996 Tier 1 ratio of 16.61% and Total capital
ratio of 9.75% exceeds the current minimum regulatory requirements of 4.00% and
6.00% respectively.
 
     The table below illustrates all of the capital requirements applicable to
First United and its subsidiaries.

     First United's Subsidiary Banks are subject to a variety of regulations
concerning the maintenance of reserves against deposits, limitations on the
rates that can be charged on loans or paid on deposits, branching, restrictions
on the nature and amounts of loans and investments that can be made and limits

     The Subsidiary Banks are limited in the amount of dividends they may
declare. Prior approval must be obtained from the appropriate regulatory
authorities before dividends can be paid by the Subsidiary Banks to First United
if the amount of adjusted capital, surplus and retained earnings is below
defined regulatory limits. As of December 31, 1996 First United's Subsidiary
Banks had available for payment of dividends without regulatory approval,
approximately $16,508,000 of undistributed earnings plus the net income earned
in 1997. The Subsidiary Banks are also restricted from extending credit or
making loans to or investments in First United and certain other affiliates as
defined in the Act. Furthermore, loans and extensions of credit are subject to
certain other collateral requirements.

MANAGEMENT'S DISCUSSION AND ANALYSIS
 
     The following discussion and analysis highlights the significant factors
affecting Citizens' consolidated financial statements. For a more complete
understanding of the following discussion, reference should be made to Citizens'
consolidated financial statements and related notes thereto presented elsewhere
in this Proxy Statement.
 
BALANCE SHEET ANALYSIS
 
     Financial Condition. The total assets of Citizens increased by $15,397,000
or 6.42% between December 31, 1996 and 1995. The increase was due to growth in
investment securities, federal funds sold, and loans. At September 30, 1997,
assets were $262,996,000 compared to the December 31, 1996 level of
$255,054,000. Citizens receives a major portion of its income from earning
assets which consist of interest bearing deposits with other banks, federal
funds sold, investment securities, and loans. See Tables 1 and 2 for an analysis
of the average balances of interest-earning assets and interest-bearing
liabilities for the years ended December 31, 1996 and 1995.
 
     Citizens' loan portfolio represents a large component of the earning asset
base and has a large impact on income from earning assets. The markets in which
Citizens operates are dependent upon the small to medium size businesses and
real estate loans. As the economy of this market has improved over the past
several years, there has been an increase in loan volume, deposits, and
investment securities.
 
     Inherent in Citizens' loan portfolio is credit risk. Citizens maintains an
allowance for loan losses which is evaluated for adequacy by management.
Management's methodology to determine the adequacy of the allowance considers
review of individual loans, recent loan loss experience, current economic
conditions and the risk characteristics of the various categories of loans. See
Tables 5 through 9 for detailed information concerning the loan portfolio and
the allowance for loan losses.
 
     Investment securities are another large component of the earning asset
base. The average volume of investment securities gradually increased during the
nine months ended September 30, 1997, and the years ended December 31, 1996 and
1995. See Tables 3 and 4 for details concerning the composition and maturity
ranges of the investment portfolio.
 
     Deposits, the primary source of funding earning assets, increased by
$18,901,000 or 9.40% between December 31, 1995 and December 31, 1996. The
majority of this increase was in the certificate of deposits greater than
$100,000 category reflecting the increase in market interest rates for such
deposits. See Table 10 for a maturity analysis of certificates of deposits in
excess of $100,000 as of December 31, 1996.
 
     During the period between December 31, 1995 and December 31, 1996, Citizens
increased the level of borrowings from the Federal Home Loan Bank in order to
provide funds for the increase in loan growth.
 
     Liquidity and Interest Rate Sensitivity Management. Liquidity is the
ability of an institution to fund the needs of its borrowers, depositors, and
creditors. Based on the maturity structure and anticipated loan and deposit
funding requirements, Citizens anticipates that its liquidity requirements will
be met in the foreseeable future. Citizens' management is of the opinion that
the traditional funding sources of maturing loans and investment securities,
federal funds, the base of core deposits, the borrowing lines of credit with the
Federal Home Loan Bank and the Arkansas Bankers' Bank will be adequate to
provide liquidity needs. See Tables 4, 6, and 10 for additional information on
certain investment, loan and time deposit maturities.
 
     Capital. The Federal Reserve Board requires banks to maintain capital based
on "risk-adjusted" assets so that categories of assets with potentially higher
risk will require more capital backing than assets with lower risk. In addition,
banks are required to maintain capital to support, on a risk-adjusted basis,
certain off-balance sheet activities such as loan commitments.
 
     At September 30, 1997, Citizens' Tier 1 capital and total capital as a
percentage of total risk-adjusted assets exceeded the required minimum levels.
See Table 12 for additional information concerning Citizens' capital ratios.

EARNINGS ANALYSIS
 
     Net income for the first nine months of 1997 was approximately $2,653,000 ,
an increase of $189,000 or 7.67% over the same period in 1996. The increase was
due primarily to a $244,000 or 3.81% increase in net interest income and a
$272,000, or a 37.11% increase in other operating income. For the years ended
December 31, 1996, 1995, and 1994, net income was approximately $3,334,000,
$2,824,000, and $2,624,000, respectively. The annualized return on average
assets and return on average equity for the first nine months of 1997 was 1.35%
and 12.90%, respectively, compared to 1.34% and 12.83% for the first nine months
of 1996. For the years ended December 31, 1996, 1995, and 1994, the return on
average assets was 1.34%, 1.33%, and 1.29%, respectively, while the return on
average equity was 13.03%, 12.20%, and 12.31%, respectively.
 
     The primary components of total income and expense which affect net income
are net interest income, provision for loan losses, noninterest income,
noninterest expense and the provision for income taxes. Significant factors
affecting these categories are presented below.
 
     Net Interest Income. Net interest income for the first nine months of 1997
was $6,649,000, a 3.81% increase over the same period in 1996. The reason for
the increase was due to the increase of $12,401,000 in investment securities
during the period from December 31, 1996 to September 30, 1997. Interest on
investment securities for the nine months ended September 30, 1997 increased by
$811,000 or 14.40% compared to the corresponding period of 1996. Interest
expense for the nine months ended September 30, 1997 increased by $515,000 or
6.97% compared to the corresponding period of 1996. As a percentage of total
assets at September 30, 1997, net loans totaled 42.3% while investment
securities were 50.72%.
 
     For the years ended December 31, 1996, 1995, and 1994, net interest income
was $8,538,000, $7,186,000, and $6,830,000, respectively. The increase during
1996 compared to 1995 was due primarily to the increase in the net yield on
interest earning assets. See Tables 1 and 2 for more detailed information
regarding rate and volume factors which affected net interest income during the
three-year period ended December 31, 1996.
 
     Provision for Loan Losses. For the first nine months of 1997 Citizens
provided $375,000 for loan losses compared to $105,000 for the comparable period
in 1996. The provision for loan losses was $201,000, $60,000, and -0- for the
years ended December 31, 1996, 1995, and 1994.
 
     Net charge-offs (recoveries) on loans were $190,000 in 1996, $101,000 in
1995 and (15,000) in 1994. For the nine months ended September 30, 1997, net
charge-offs totaled $354,000. The allowance for loan losses was $1,258,000 or
1.12% of loans at September 30, 1997, compared to $1,237,000 or 1.09% at
December 31, 1996, and $1,226,000 or 1.11% at December 31, 1995. See Tables 7,
8, and 9 for more information regarding loan quality and the allowance for loan
losses.
 
     Other Operating Income. Total other operating income for the nine months
ended September 30, 1997 and 1996 was $1,005,000 and $733,000, respectively.
There was an increase in 1997 of $33,000 in service charge income compared to
September 30, 1996. Total other operating income for the year ended December 31,
1996 was $977,000, as compared to $768,000 for 1995 and $845,000 in 1994.
 
     Other Operating Expense. Total other operating expense for the nine months
ended September 30, 1997 and 1996 was $3,801,000 and $3,742,000, respectively.
 
     Total other operating expense for the year ended December 31, 1996 was
$5,086,000 as compared to $4,239,000 for 1995 and $4,199,000 in 1994.
 
     Provision for Income Taxes. Income tax expense for the nine months ended
September 30, 1997 and 1996 was $825,000 and $827,000, respectively. Income tax
expense for the years ended December 31, 1996, 1995, and 1994 was $894,000,
$831,000, and $852,000, respectively. Effective tax rates were 21.13%, 22.72%,
and 24.51%, respectively. Note 9 or Notes to the Financial Statements provides
further details of the applicable income tax expense for 1996, 1995, and 1994.

     If interest on nonaccrual loans had been accrued for 1996, such income
would not have been material. The interest which was included in earnings for
1996 for nonaccrual loans is immaterial.
 
     At December 31, 1996, Citizens had no loan concentrations greater than ten
percent (10%) of total loans except as shown in Table 5.
 
     Citizens does not accrue interest on any loan for which payment of interest
or principal is not expected, on any loan which is seriously delinquent unless
the obligation is both well secured and in the process of collection, or on any
loan that is maintained on a cash basis due to deterioration in the financial
condition of the borrower. Management considers a debt to be "well secured" if
it is secured by collateral in the form of liens on or pledges of real or
personal property that have a realizable value sufficient to discharge the debt
in full or by the guaranty of a financially responsible party. A debt is
considered to be "in process of collection" if, based on a probable specific
event, it is expected that the loan will be repaid or brought current. At
December 31, 1996, Citizens has no loans which are not included in the
nonperforming or past due categories above about which management has serious
doubts as to their collectibility.

    loan loss experience, and management's reviews of individual loans.

(1) This column represents the year in which the directorship commenced. If a
    person serves as director for both Citizens and one or both of its
    subsidiaries, the year disclosed reflects the date the directorship in
    Citizens commenced.
 
     During 1996, the Board of Directors of Citizens held twelve (12) regularly
scheduled meetings and all incumbent directors then in office attended more than
seventy-five percent of the meetings except one director who had four (4)
absences. Two (2) other directors were absent twice. The Board of Directors has
an Executive Committee, Investment Committee, Loan Review Committee, Audit
Committee, and CRA Committee.
 
TRANSACTIONS AND MANAGEMENT
 
     Directors and executive officers of Citizens, their associates and members
of immediate families were customers of and had transactions including loans and
commitments to borrow from Citizens' subsidiaries in the ordinary course of
business during 1996. All such loans and commitments were made by Citizens'
subsidiaries on substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable transactions with
other persons and did not involve more than normal risk of collectibility or
present other unfavorable features. Similar transactions may be expected to take
place in the ordinary course of business in the future. On September 30, 1997,
the aggregate of these related party loans was approximately $4,689,000 or
approximately 4.17% of total loans outstanding of the subsidiaries.
 
PRINCIPAL STOCKHOLDERS OF CITIZENS
 
     All persons who as of September 30, 1997, owned of record or beneficially

COMPARISON OF RIGHTS OF HOLDERS OF CITIZENS COMMON STOCK AND FIRST UNITED COMMON
STOCK
 
     Citizens is a corporation organized and existing under the laws of the
State of Arkansas including the Arkansas Business Corporation Act of 1965. First
United is a corporation organized and existing under the laws of the State of
Arkansas, including the Arkansas Business Corporation Act of 1987 ("1987 Act").
Holders of Citizens common stock have the rights, privileges and duties provided
by the 1965 Act, while the holders of First United Common Stock have the rights,
privileges and duties provided by the 1987 Act. For a detailed discussion of all
material differences between the rights of security holders of Citizens, and the
rights of security holders of First United, see "Election by Citizens
Stockholders under the 1987 Act -- Result of Election."
 
     The affirmative vote of the holders of at least two-thirds of the
outstanding shares of Citizens common stock may authorize the Merger pursuant to
the 1965 Act. First United's Articles of Incorporation requires approval by
two-thirds of all shares issued and outstanding that are entitled to vote for
all mergers requiring the approval of First United Shareholders.
 
     Both the holders of Citizens common stock and the holders of First United
Common Stock are entitled to cumulative voting in the election of directors.
Pursuant to First United's By-Laws, the number of directors of the corporation
may not be less than five nor more than twenty-five. The Citizens By-Laws
require that the number of directors may not be less than five nor more than
twenty-five. Neither holders of Citizens common stock nor holders of First
United Common Stock have preemptive rights with respect to issuance of
additional securities.
 
     Both Citizens and First United have corporate power to indemnify their
officers and directors with respect to certain liabilities. Under the 1987 Act,
the ability to indemnify officers and directors with respect to
 
                                       46
<PAGE>   54
 
liabilities incurred by them in their conduct of the business of the corporation
is broader than under the 1965 Act. Such power is limited, however, by
applicable federal laws and regulations including federal banking laws and
regulations and the applicable state law.
 
     First United's Articles of Incorporation contain a paragraph that may have
the effect of operating as an anti-takeover provision. Paragraph SEVENTH
contains a super-majority voting requirement of two-thirds ( 2/3) of all shares
issued and outstanding that are entitled to vote for approval of (1) a merger or
share exchange with another corporation unless such merger or share exchange can
be effected under the authority of state law without shareholder approval, (2) a
transaction to sell, exchange, lease or otherwise dispose of all, or
substantially all, of the corporation's assets and property except where
accomplished in the usual and regular course of business, (3) a transaction
effecting a dissolution or liquidation of the corporation, or (4) any amendment
of the Articles of Incorporation. The Citizens Articles of Incorporation do not
contain a like provision, but the 1965 Act requires the affirmative vote of the
holders of at least two-thirds of the outstanding shares to approve a merger.

                          INDEPENDENT AUDITOR'S REPORT
 
Board of Directors
Citizens National Bancshares, Inc.
Hope, Arkansas
 
     We have audited the accompanying consolidated balance sheets of Citizens
National Bancshares, Inc. as of December 31, 1996 and 1995, and the related
consolidated statements of income, stockholders' equity and cash flows for each
of the three years in the period ended December 31, 1996. These financial
statements are the responsibility of Bancshares' management. Our responsibility
is to express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Citizens
National Bancshares, Inc. as of December 31, 1996 and 1995, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1996, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
(INFORMATION AS OF AND FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1997 IS
                                   UNAUDITED)
                             (DOLLARS IN THOUSANDS)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies of Citizens National Bancshares, Inc.
("Bancshares") conform with generally accepted accounting principles and
practices within the banking industry. The financial statements for the nine
months ended September 30, 1997 and 1996 are unaudited and, in the opinion of
management, include all adjustments necessary (which consist of only normal
recurring adjustments) for a fair presentation of the financial position,
results of operations and cash flows for the interim periods. The financial
position and results of operations of the interim periods are not necessarily
indicative of the financial position and results of operations that may be
obtained for a full fiscal year.
 
     The policies that materially affect financial position and the results of
operations are summarized as follows:
 
          a. Basis of presentation -- The consolidated financial statements
     include the accounts of Bancshares and its wholly owned subsidiaries,
     Citizens National Bank of Hope and Peoples Bancshares, Inc. and its wholly
     owned subsidiary Peoples Bank and Loan of Lewisville (the "Banks"). As
     discussed in Note 11, effective December 1, 1995, Bancshares acquired all
     the outstanding stock of Peoples Bancshares, Inc., the parent holding
     company of Peoples Bank and Loan Company ("Peoples Bank") in a business
     combination which was accounted for as a purchase transaction. Accordingly,
     the operations of Peoples subsequent to the date of acquisition are
     included in the operations of Bancshares for the years ended December 31,
     1995 and 1996. All material intercompany accounts and transactions have
     been eliminated in consolidation.
 
          b. Nature of operations -- Citizens National Bank of Hope operates
     under a national bank charter and Peoples Bank and Loan of Lewisville
     operates under a state charter. The Banks are subject to the regulations of
     the Office of the Comptroller of the Currency or the State Banking
     Commission and the Federal Deposit Insurance Corporation. The Banks provide
     full banking services, including trust services, to an area located in the
     southwest region of Arkansas.
 
          c. Estimates -- The preparation of financial statements in conformity
     with generally accepted accounting principles requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the financial statements and the reported amounts of revenues and
     expenses during the reporting period. Actual results could differ from
     those estimates.
 
          d. Cash and cash equivalents -- For the purpose of presentation in the
     statement of cash flows, cash and cash equivalents are defined as those
     amounts included in the balance sheet caption "Cash and Due from Banks."
 
          e. Investments securities -- Debt and equity securities are classified
     into three categories: securities held as trading securities, securities
     which are available-for-sale and securities being held-to-maturity.
     Securities classified as trading securities are reported at fair value,
     with realized gains and losses included in earnings. Securities classified
     as available-for-sale are reported at fair value, with unrealized gains and
     losses excluded from earnings and reported as a separate component of
     stockholders' equity. Securities classified as held-to-maturity are
     reported at amortized cost.
 
          Gains and losses on sales of securities are recognized when realized
     on a specific identification basis. Premiums and discounts are amortized
     into interest income using a level yield method.
 
          f. Loans -- Interest on commercial loans and real estate mortgage
     loans is credited to income based upon the principal amount outstanding.
     Interest on installment loans is credited to income based upon the interest
     method and upon the principal amount outstanding.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
          g. Reserve for loan losses -- For financial reporting purposes, the
     reserve for loan losses is established through a provision for loan losses
     charged to expense. Loans are charged against the reserve for loan losses
     when management believes that the collectibility of the principal is
     unlikely. The reserve is an amount that management believes will be
     adequate to absorb possible losses on existing loans that may become
     uncollectible, based on evaluations of the collectibility of loans and
     prior loan loss experience. The evaluations take into consideration such
     factors as changes in the nature and volume of the loan portfolio, overall
     portfolio quality, review of specific problem loans, and current economic
     conditions that may affect the borrowers' ability to pay. Accrual of
     interest is discontinued on a loan when management believes, after
     considering economic and business conditions and collection efforts, that
     the borrowers' financial condition is such that collection of interest is
     doubtful. For income tax purposes, Bancshares utilizes the direct write-off
     method for loan losses.
 
          h. Bank premises and equipment -- Bancshares premises and equipment
     are stated at cost, less accumulated depreciation. Depreciation is charged
     to operating expenses over the estimated useful lives of the assets and is
     computed using the straight-line method for financial statement purposes
     and accelerated methods for tax purposes.
 
          i. Acquisition costs -- The costs associated with the Bancshares'
     acquisition of certain assets and liabilities of a savings and loan
     association are being amortized on a straight-line basis over ten years.
     The excess of purchase price over fair value arising from the acquisition
     of Peoples Bancshares, Inc. is being amortized on a straight-line basis
     over fifteen years.
 
          j. Real estate acquired through foreclosure -- Real estate properties
     acquired through or in lieu of loan foreclosure are to be sold and are
     initially recorded at fair value at the date of foreclosure establishing a
     new cost basis. Valuations are periodically performed by management and the
     real estate is carried at the lower of carrying amount of fair value less
     cost to sell. Gains and losses from the sale of other real estate are
     recorded in other income, and expenses used to maintain the properties are
     included as operating expenses.
 
          k. Income taxes -- The Company utilizes the liability method of
     accounting for income taxes. This method requires the recognition of
     deferred tax assets and liabilities for the expected future tax
     consequences of events that have been recognized in the financial
     statements or tax returns. Under this method, deferred tax assets or
     liabilities are determined based upon the difference between the values of
     the assets and liabilities as reflected in the financial statement and
     their related tax basis using enacted tax rates in effect for the year in
     which the differences are expected to be recovered or settled. As changes
     in tax laws or rates are enacted, deferred tax assets and liabilities are
     adjusted through the provision for income taxes.
 
          Bancshares and its subsidiaries file consolidated income tax returns.
     Its subsidiaries provide for income taxes on a separate return basis, and
     remit to Bancshares amounts determined to be currently payable.
 
          l. Trust department income -- Property, other than cash deposits, held
     by Bancshares' trust department in fiduciary or agency capacities for its
     customers, are not included in the accompanying financial statements, since
     such items are not assets of Bancshares. Trust department income has been
     recognized on the cash basis in accordance with customary banking practice,
     which does not materially affect reported net income.
 
          m. Pension plan -- Bancshares has defined benefit pension plans
     covering substantially all employees. Costs of the plans, based on
     actuarial computations of current and future benefits for employees, are
     charged to operating expenses and are funded as accrued.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
          n. Earnings per common share -- Net income per common share is
     calculated based on the weighted average number of common shares
     outstanding during the period. Reported earnings per share amounts are
     based on 498,241, 498,460 and 498,525 weighted average common shares
     outstanding at December 31, 1994, 1995 and 1996 and 498,525 and 497,960
     weighted average common shares at September 30, 1996 and 1997,
     respectively.
 
          o. Financial instruments -- In the ordinary course of business,
     Bancshares has entered into off-balance sheet financial instruments
     consisting of commitments to extend credit, commitments under credit card
     arrangements, and letters of credit. Such financial instruments are
     recorded in the financial statements when they are funded or related fees
     are incurred or received.
 
2. INVESTMENT SECURITIES

9. COMMITMENTS AND CONTINGENCIES
 
     a. Bancshares is a party to financial instruments with off-balance sheet
risk in the normal course of business to meet the financing needs of it
customers and to reduce its own exposure to fluctuation in interest rates. These
financial instruments include commitments to extend credit, standby letters of
credit and interest rate caps and floors written.
 
     Bancshares' exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit is
represented by the contractual notional amount of those instruments. Bancshares
has the same credit policies in making commitments and conditional obligations
as it does for on-balance sheet instruments. For interest rate caps and floors,
the contract or notional amounts do not represent exposure to credit loss.
 
     Financial instruments, whose contract amounts represents credit risk,
consist of loan commitments and unfunded lines of credit of approximately $5,244
and $6,936 at December 31, 1995 and 1996, respectively.
 
     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since these commitments may expire without
being drawn upon, the total commitment amount does not necessarily represent
future cash requirements. Bancshares evaluates each customer's credit worthiness
on a case-by-case basis. The amount of collateral obtained, if deemed necessary
by Bancshares upon extension of credit, is based on management's credit
evaluation of the counterpart. Collateral held varies but may include accounts
receivable, inventory, property, plant and equipment, and income-producing
commercial properties.
 
     b. Bancshares grants agribusiness, commercial and residential loans to
customers within its lending region. Bancshares maintains a limited diversified
loan portfolio with a high concentration on residential and agribusiness loans.
 
10. PENSION PLAN

     For the years ended December 31, 1995 and 1996, weighted-average assumed
discount rates of 7.00% and rates of compensation increase of 4.50% were used to
measure the actuarially projected benefit obligation. The weighted-average
expected long-term rate of return on plan assets was 7.00% for the years ended
December 31, 1995 and 1996.
 
11. ACQUISITION
 
     Effective December 1, 1995, Bancshares acquired all the outstanding stock
of Peoples Bancshares, Inc., the parent holding company of Peoples Bank and Loan
Company ("Peoples Bank") in Lewisville, Arkansas, for approximately $3,100. In
addition, in connection with this acquisition, Bancshares assumed liability for
outstanding debt and accrued interest payable totaling approximately $703. This
business combination was accounted for as a purchase transaction. Accordingly,
the assets and liabilities of Peoples Bancshares, Inc. and Peoples Bank were
recorded at their fair value and goodwill totaling approximately $653 has been
included in other assets.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used to estimate the fair values
of each class of financial instruments for which it is practicable to estimate a
value.
 
          a. Cash and short term investments -- For those short term
     instruments, the carrying amount is a reasonable estimate of fair value.
 
          b. Investment securities -- For marketable equity securities held for
     investment purposes, fair values are based on quoted market prices or
     dealer quotes. If a quoted market price is not available, fair value is
     estimated using quoted market prices for similar securities or the carrying
     amount.
 
          c. Trading account securities -- The fair values of trading account
     securities are based on quoted market prices or dealer quotes.
 
          d. Loans -- The fair value of loans is estimated by discounting the
     future cash flows using the current rate at which similar loans would be
     made to borrowers with similar credit ratings and for the same remaining
     maturities.
 
          e. Deposit liabilities -- The fair value of demand deposits, savings
     accounts and certain money market deposits is the amount payable on demand
     at the reporting date. The fair value of fixed maturity certificates is
     estimated using the rates currently offered for deposits of similar
     remaining maturities.
 
          f. Note payable -- For those short term instruments, the carrying
     amount is a reasonable estimate of fair value.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
          g. Commitments to extend credit and standby letters of credit -- The
     fair value of commitments is based upon the remaining terms of the
     agreements and the difference between current levels of interest rates and
     committed rates.
 
     The following table presents the estimated fair values of Bancshares'
financial instruments. The fair values of certain of these instruments were
calculated by discounting expected cash flows, which involves significant
judgements by management and uncertainties. Fair value is the estimated amount
at which financial assets or liabilities could be exchanged in a current
transaction between willing parties, other than in a forced or liquidation sale.
Because no market exists for certain of these financial instruments and because
management does not intend to sell these financial instruments, Bancshares does
not know whether the fair values shown below represent values at which the
respective financial instruments could be sold individually or in the aggregate.

14. NEW AUTHORITATIVE PRONOUNCEMENTS
 
     The Financial Accounting Standards Board ("FASB") has issued Statement of
Financial Accounting Standards ("SFAS") No. 125, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities". SFAS No. 125
is effective for transfers and servicing of financial assets and extinguishment
of liabilities occurring after December 31, 1996. Earlier application is
prohibited. Adoption on January 1, 1997 is not expected to have a material
impact on the Company. The FASB deferred some provisions of SFAS No. 125, which
are not expected to be relevant to the Company.
 
     The FASB issued SFAS No. 128, "Earnings Per Share", and SFAS No. 129,
"Disclosure of Information about Capital Structure" in February 1997. SFAS No.
128 simplifies the earnings per share ("EPS") calculations required by
Accounting Principles Board ("APB") Opinion No. 15, and related interpretations,
by replacing the presentation of primary EPS with a presentation of basic EPS.
SFAS No. 128 requires dual presentation of basic and diluted EPS by entities
with complex capital structures. Basic EPS includes no dilution and is computed
by dividing income available to common stockholders by the weighted-average
number of common shares outstanding for the period. Diluted EPS reflects the
potential dilution of securities that could share in the earnings of an entity,
similar to the fully diluted EPS of APB Opinion No. 15. SFAS No. 128 is
effective for financial statements issued for periods ending after December 15,
1997, including interim periods; earlier application is not permitted. When
adopted, SFAS No. 128 will require restatement of all prior-period EPS data
presented. However, the Company's prior years EPS will not be effected by these
restatements.
 
     SFAS No. 129 does not change any previous disclosure requirements, but
rather consolidated existing disclosure requirements for ease of retrieval.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of

outstanding shares of capital stock of The Citizens National Bank of Hope, Hope,
Arkansas ("CNB") and Peoples Bank & Loan Company, Lewisville, Arkansas
("Peoples"); and CNB owns one hundred percent (100%) of the issued and
outstanding shares of capital stock of Citizens Investment Services, Inc.

     WHEREAS, Bancshares desires to acquire one hundred percent (100%) of the

conditions hereinafter set forth through the merger of Citizens with and into
Bancshares, (the "Merger") pursuant to a Plan of Merger in substantially the
form attached hereto as Exhibit A (the "Plan of Merger"); and
 
     WHEREAS, the respective Boards of Directors of Bancshares and Citizens
believe that such proposed Merger and the exchange of shares of Bancshares Stock
(as defined in Section 2.01(a) hereof) for the Citizens Common Stock, pursuant
and subject to the terms of this Agreement and the Plan of Merger (the "Merger
Agreements"), is desirable and in the best interests of their respective
corporations and shareholders; and
 
     WHEREAS, Bancshares and Citizens desire to make certain representations,
warranties and agreements in connection with the Merger and also to prescribe
various conditions to the Merger;
 
     NOW, THEREFORE, in consideration of the promises and the representations,
warranties and agreements herein contained, the parties hereto agree as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     1.01. The Merger. Subject to the terms and conditions of this Agreement,
Bancshares and Citizens agree to effect the Merger of Citizens with and into
Bancshares in accordance with the Arkansas Business Corporation Act (the
"ABCA").
 
     1.02. Effective Time of the Merger. Subject to the provisions of this
Agreement, articles of merger shall be duly prepared and executed by Bancshares
and Citizens (the "Articles of Merger") and thereafter delivered to the
Secretary of State of Arkansas for filing, as provided in the ABCA, as soon as

Merger shall become effective upon the filing of the Articles of Merger with the

     1.03. Closing. The closing of the Merger (the "Closing") will take place at
the offices of Bancshares at a time and on a date (the "Closing Date") to be

                                   ARTICLE II
 
                              EFFECT OF THE MERGER
 
     2.01. Effect on Common Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of
Citizens Common Stock ("Citizens Shareholder"), but subject to the rights of
dissenting shareholders of Citizens:
 
          (a) Conversion of Citizens Common Stock. The purchase price paid by
     Bancshares shall be equal to 1,570,000 shares of Bancshares Common Stock,
     $1.00 par value (the "Bancshares Stock"). One hundred percent of the issued
     and outstanding shares of Citizens Common Stock shall be converted into the
     right to receive an aggregate amount of fully paid and nonassessable shares
     of voting common stock, $1.00 par value, of Bancshares. Each Citizens
     Shareholder shall be entitled to receive a pro rata portion of the
     Bancshares Stock based upon each Citizens Shareholder's pro rata ownership
     of the total of issued and outstanding shares of Citizens Common Stock at
     the Effective Time. Fractional shares of Bancshares Stock shall not be
     issued. Any Seller entitled to receive a fractional share shall receive a
     cash payment in lieu thereof equal to the value of the fractional share
     based on the Bancshares Average Price. The Bancshares Average Price shall
     be the average sales price per share of Bancshares common stock for all
     trades occurring during the period of 10 trading days on which one or more
     trades actually takes place and which ends immediately prior to the second
     trading day preceding the Closing Date.
 
          (b) Cancellation of Shares. All shares of Citizens Common Stock issued
     and outstanding immediately prior to the Effective Time shall no longer be
     outstanding and shall automatically be cancelled and retired and shall
     cease to exist, and each holder of a certificate representing any such
     shares shall cease to have any rights with respect thereto, except the
     right to receive a pro rata number of shares of Bancshares Stock to be
     issued in consideration therefor upon the surrender of such certificate in
     accordance with the Plan of Merger.
 
          (c) Anti-Dilution. If prior to the Effective Time Bancshares shall
     declare a stock dividend or subdivide, split up, reclassify or combine its
     shares of Bancshares common stock or make a distribution on Bancshares
     common stock of any security, appropriate adjustment or adjustments will be
     made in the conversion rate set forth in subsection (a).
 
          (d) Registration. The Bancshares Stock shall when issued be subject to
     and covered by an effective registration statement as filed under the
     Securities Act of 1933 (the "Securities Act") and such issuance shall
     comply with any applicable state "Blue Sky" laws.
 
          (e) Termination of 401(k) Plan. As soon as practical after execution
     of this Agreement, Citizens shall cause Citizens, CNB, Peoples and CIS to
     make all filings, take all action and receive all approvals necessary and
     appropriate to allow termination of the Citizens 401(k) plan immediately
     prior to the Closing Date. Bancshares shall assist Citizens in
     accomplishing the above procedures. If, as of the Effective Time, all
     assets from the terminated plan have not yet been distributed, Bancshares
     shall complete the liquidation process for the Citizens 401(k) plan. Prior
     to and effective as of the Effective Time, Citizens shall appoint Kathy
     Struckman as the Plan Administrator of the Citizens 401(k) Plan and shall
     authorize Kathy Struckman to execute all documents necessary to complete
     the liquidation process, including the execution of the annual returns.
     Bancshares shall indemnify Kathy Struckman against any and all claims,
     expenses, liabilities, damages and losses which may result from her
     assumption of the status of Plan Administrator of Citizens 401(k) Plan as
     of and subsequent to the Effective Time. To the extent that any Citizens
     Employee becomes subject to a surrender or withdrawal fee under any group
     annuity contract, or other investment vehicle, which funds the Citizens
     401(k) plan, Bancshares shall reimburse such Citizens Employee for any such
     fee, as current compensation, within thirty (30) days of the date such fee
     is incurred. With respect to the 401(k) plan maintained by Bancshares, all
     Citizens Employees shall, as of the Effective Time, be immediately eligible
     to participate in such plan. To the extent necessary to achieve immediate
     participation, Bancshares shall amend such plan to credit service with
     Citizens for purposes of eligibility and vesting.

     2.02 Merger and Termination of Defined Benefit Plans. Citizens and Peoples
shall take all action and receive all approvals necessary and appropriate to
merge the Peoples Bank and Loan Company Employees Pension Plan ("Peoples Pension
Plan") into the Citizens National Bank of Hope Retirement Plan ("Citizens
Pension Plan") during 1997. The Citizens Pension Plan shall be the surviving
plan. Bancshares, through its counsel, shall assume responsibility for ensuring
that all necessary documents, filings and actions are timely prepared and made
to accomplish the merger. As soon as practical after execution of this
Agreement, Citizens shall take all action and receive all approvals necessary
and appropriate to terminate the Citizens Pension Plan (as merged with the
Peoples Plan), with such termination to be effective immediately prior to the
Closing Date. Bancshares, through its counsel, shall assume responsibility for
ensuring that all necessary documents, filings and actions are timely prepared
and made to accomplish the termination. Bancshares' counsel shall provide copies
of all such documentation and filings to Citizens' counsel. Benefits shall
continue to accrue under the Citizens Pension Plan up until the Closing Date.
There shall be no amendments made to the Citizens Pension Plan prior to
termination, except for amendments which are necessary either to: (a) effect the
merger of the Peoples Pension Plan into the Citizens Pension Plan; or (b)
maintain the qualified status of the Plan. At the time of distribution,
participants in the Citizens Pension Plan will be given the opportunity to
rollover their benefit directly into the 401(k) plan maintained by Bancshares.
 
     2.03. Approval By Shareholders. Consummation of the Merger shall be
contingent upon its approval by the legally required votes of the shares of
Citizens Common Stock and Bancshares Common Stock at shareholders meetings duly
called for the purpose of voting on the Merger. In the event the number of
shares owned by Citizens Shareholders exercising dissenters' rights would or
could, in the written opinion of Bancshares' outside accountants, reasonably be
expected to cause the cash consideration paid by Bancshares to dissenters to
jeopardize Bancshares' ability to account for the Merger as a pooling of
interests then Bancshares shall have the right to terminate this Agreement. The
Board of Directors of Citizens and Bancshares shall recommend approval of the
Merger to their respective shareholders.
 
                                  ARTICLE III

insolvency, reorganization, arrangement, moratorium or other similar laws
relating to or affecting the rights of creditors and by general principles of
equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law). The execution and delivery of this Agreement and the Plan
of Merger do not, and the consummation of the transactions contemplated hereby
and thereby will not, conflict with, or result in any violation of, or default

foreign (a "Governmental Entity"), is required by or with respect to Citizens,
CNB, Peoples or CIS in connection with the execution and delivery of this
Agreement and the Plan of Merger by Citizens or the consummation by Citizens of
the transactions contemplated hereby and thereby.

             (i) deposit liabilities and interest payable thereon,
 
             (ii) federal funds purchased and securities sold under repurchase
                  agreements and interest payable thereon,

<PAGE>   79
 
(all such reports and statements are collectively referred to herein as the
"Citizens Reports"), except where such failure to file would not have a material
adverse effect on the business operations or financial condition of Citizens or
any Citizens Subsidiary. The Citizens Reports complied in all material respects
with all of the statutes, rules and regulations enforced or promulgated by the
regulatory authority with which they were filed and did 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.
 
     3.07. Information Supplied. None of the information supplied or to be
supplied by Citizens for inclusion or incorporation by reference in any document
to be filed with the Securities and Exchange Commission ("SEC"), the FRB, or any
regulatory agency in connection with the transactions contemplated hereby,

state a material fact required to be stated therein in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. Citizens has made available to Bancshares all financial and
other information reasonably requested by Bancshares.
 
     3.08. Authorizations; Compliance with Applicable Laws. Citizens, CNB,
Peoples and CIS hold all authorizations, permits, licenses, variances,
exemptions, orders and approvals of all Governmental Entities which are material
to the operations of the businesses of Citizens, CNB, Peoples or CIS (the
"Citizens Permits"), including appropriate authorizations from the ASBD.
Citizens, CNB, Peoples and CIS are in compliance with the terms of the Citizens
Permits, except where the failure so to comply would not have a material adverse
effect on Citizens, CNB, Peoples or CIS. To the knowledge of Citizens, the
businesses of Citizens, CNB, Peoples and CIS are not being conducted in
violation of any federal, state or local law, statute, ordinance or regulation
of any Governmental Entity (collectively "Laws"), including, without limitation,
Regulation O of the FRB, except for possible violations which individually or in
the aggregate do not and, insofar as reasonably can be foreseen, in the future
will not, have a material adverse effect on Citizens, CNB, Peoples or CIS. No
investigation or review by any Governmental Entity with respect to Citizens,
CNB, Peoples or CIS is pending or, to the best of their knowledge, threatened,
nor has any Governmental Entity indicated an intention to conduct the same.
Without limiting the foregoing, to the knowledge of Citizens there have been no
acts or omissions occurring on or with respect to real estate currently or
previously owned, leased or otherwise used in the ordinary course of business by
Citizens, CNB, Peoples or CIS in which Citizens, CNB, Peoples or CIS has or had
an investment or security interest (by mortgage, deed of trust, or otherwise),
including, without limitation, properties under foreclosure, properties held by
Citizens, CNB, Peoples or CIS in its capacity as a trustee, or properties in
which any venture capital or similar unit of Citizens or Peoples has or had an
interest (the "Citizens Property"), which, to the knowledge of Citizens,
constitute or result, or may have constituted or resulted, in the creation of
any federal, state or common law nuisance (whether or not the nuisance condition
is, or was, foreseen or unforeseen) or which, to the knowledge of Citizens, do
not comply or have not complied with federal, state or local environmental laws
including, without limitation, the Clean Water Act, the Clean Air Act, the
Resource Conservation and Recovery Act, the Toxic Substances Control Act and the
Comprehensive Environmental, Response, Compensation and Liability Act, as
amended, and their state and local law counterparts, all rules and regulations
promulgated thereunder and all other legal requirements associated with the
ownership and use of the Citizens Property (collectively, "Environmental Laws"),
and as a result of which acts or omissions Citizens, CNB or Peoples is subject
to or reasonably likely to incur a material liability or suffer a diminution in
value of any interest exceeding $100,000.00. To their knowledge, neither
Citizens, CNB, Peoples nor CIS is subject to or reasonably likely to incur a
material liability or suffer a diminution in value of any interest exceeding
$100,000.00 as a result of its ownership, lease, operation, or use of any
Citizens Property or as a result of its investment or security interest (as
described above) in any Citizens Property (a) that is contaminated by or
contains any hazardous waste, toxic substances or related materials, including
without limitation asbestos, PCBs, pesticides, herbicides, petroleum products,
substances defined as "hazardous substances" or "toxic substances" in the
Environmental Laws, and any other substances or waste that is hazardous to human
health or the environment (collectively, "Toxic Substances"), or (b) on which

Pension Plan or a funded Welfare Plan nor any trust of such plan has been
terminated, nor has there been any "reportable event" (as that term is defined

the Bancshares Permits, except where the failure to comply would not have a
material adverse effect on Bancshares. The businesses of Bancshares and its
subsidiaries are not being conducted in violation of any Laws, including,

or its subsidiaries is pending or threatened, nor has any Governmental Entity
indicated an intention to conduct the same. Without limiting the foregoing,
there have been no acts or omissions occurring on or with respect to real estate
currently or previously owned, leased or otherwise used by Bancshares or any
Bancshares subsidiary or in which Bancshares or any Bancshares subsidiary has or
had an investment or security interest (by mortgage, deed of trust, or
otherwise), including, without limitation, properties under foreclosure,
properties held by Bancshares or a Bancshares subsidiary in its capacity as a
trustee, or properties in which any venture capital or similar unit of
Bancshares or a Bancshares subsidiary has or had an interest (the "Bancshares
Property"), which constitute or result, or may have constituted or resulted, in
the creation of any federal, state or common law nuisance (whether or not the
nuisance condition is, or was, foreseen or unforeseen) or which do not comply or
have not complied with federal, state or local Environmental Laws, and as a
result of which acts or omissions Bancshares or a Bancshares subsidiary is
subject to or reasonably likely to incur a material liability. Neither
Bancshares nor any Bancshares subsidiary is subject to or reasonably likely to
incur a material liability as a result of its ownership, lease, operation, or
use of any Bancshares Property or as a result of its investment or security
interest (as described above) in any Bancshares Property (a) that is
contaminated by or contains any hazardous waste, toxic substances or related
materials, including without limitation asbestos, PCBs, pesticides, herbicides,
petroleum products, substances defined as "hazardous substances" or "toxic
substances" in the Environmental Laws, and any other Toxic Substances, or (b) on
which any Toxic Substance has been stored, disposed of, placed, or used in the
construction thereof. No claim, action, suit or proceeding is pending against
Bancshares or any Bancshares subsidiary relating to the Bancshares Property
before any court or other governmental authority or arbitration tribunal

authority or other Governmental Entity, or any judgment, order, writ,
injunction, decree or award of any Governmental Entity or arbitrator, including,

reasonably be expected to have a material adverse effect on Bancshares and (c)
there are no uncured material violations, or violations with respect to which
material refunds or restitutions may be required, cited in any compliance report
to Bancshares or any Bancshares subsidiary as a result of the examination by any
bank regulatory authority.
 
     4.08. Regulatory Approval. To the knowledge of Bancshares, there is no
reason that approval from regulatory authorities, including but not limited to
the SEC, necessary to consummate the transactions contemplated hereby cannot or
will not be obtained in the ordinary course, except as has been disclosed in
writing to Citizens.
 
     4.09. No Untrue Statements. To Bancshares knowledge, no representation or
warranty hereunder or information contained in any financial statement or any
other document delivered to Citizens pursuant to this Agreement contains any

or to which its properties or assets are subject.

   EFFECT OF THE MERGER ON THE COMMON STOCK OF THE CONSTITUENT CORPORATIONS;
                            EXCHANGE OF CERTIFICATES
 
     2.01. Conversion of Citizens Common Stock. As of the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
shares of Citizens Common Stock, but subject to the rights of dissenting
shareholders of Citizens:
 
          (a) Conversion of Citizens Common Stock. The issued and outstanding
     shares of Citizens Common Stock shall be converted in accordance with the
     Agreement into the right to receive the consideration provided in Section
     2.01 of the Agreement.
 
          (b) Cancellation of Shares. All shares of Citizens Common Stock issued
     and outstanding immediately prior to the Effective Time shall no longer be
     outstanding and shall automatically be cancelled and retired and shall
     cease to exist, and each holder of a certificate representing any such
     shares shall cease to have any rights with respect thereto, except the
     right to receive a pro rata amount of the consideration provided therefor
     upon the surrender of such certificate in accordance with the Plan of
     Merger.
 
     2.02. Exchange of Certificates. (a) Exchange Agent. As of the Effective
Time, Bancshares shall deposit with the Trust Department of First National Bank
of El Dorado, El Dorado, Arkansas or such other bank or trust company designated
by Bancshares (the "Exchange Agent") for the benefit of the holders of shares of
Citizens Common Stock, for exchange in accordance with this Article II through
the Exchange Agent, the number of shares of Bancshares common stock and cash
(the "Exchange Fund") to be paid pursuant to Section 2.01 in exchange for shares
of Citizens Common Stock outstanding immediately prior to the Effective Time.
 
     (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of Citizens Common Stock (the "Certificates")
whose shares were converted into the right to receive shares of Bancshares
common stock and cash pursuant to Section 2.01, (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other provisions as
Bancshares may reasonably specify) and (ii) instructions for use in effecting
the surrender of the Certificates in exchange for the Bancshares common stock
and cash payment due. Upon surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as may be appointed by
Bancshares, together with such letter of transmittal, duly executed, the holder
of such Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole
 
                                     A-I-27
<PAGE>   101
 
shares of Bancshares common stock and cash which such holder has the right to
receive pursuant to Section 2.01 of the Agreement, and the Certificate so
surrendered shall forthwith be cancelled. Until surrendered as contemplated by
this Section 2.02, each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender the
consideration specified in Section 2.01 of the Agreement.
 
     (c) Distributions with Respect to Unexchanged Shares. No delivery of
Bancshares common stock or cash payment of any kind shall be made to the holder
of any unsurrendered Certificate until the holder of record of such Certificate
shall surrender such Certificate. However, Citizens Shareholders shall be
entitled to receive, subject to applicable abandoned property, escheat and
similar laws, payment of dividends declared by Bancshares subsequent to the
Effective Time, but delivery of payment of such dividends will not be required
of Bancshares until such persons have delivered their certificates representing
shares of Citizens common stock in exchange for certificates representing shares
of Bancshares common stock in accordance with the provisions of Section 2.02(b)
above.
 
     (d) No Further Ownership Rights in Citizens Common Stock. The consideration
paid upon the surrender of shares of Citizens Common Stock in accordance with
the terms hereof including any cash shall be deemed to have been paid in full
satisfaction of all rights pertaining to such shares of Citizens Common Stock,
and there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of Citizens Common Stock which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be cancelled and payment shall be made as provided in this
Plan of Merger.
 
     (e) Termination of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the shareholders of Citizens for six months after the
Effective Time shall be delivered to Bancshares, upon demand, and any
shareholders of Citizens who have not theretofore complied with this Section
2.02 shall thereafter look only to Bancshares for payment of the Bancshares
common stock and cash due for their Citizens stock.
 
     (f) No Liability. Neither Bancshares nor Citizens shall be liable to any
holder of shares of Citizens Common Stock for shares of Bancshares common stock
or cash from the Exchange Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

First United Bancshares, Inc.
Main and Washington Streets
El Dorado, Arkansas 71730
 
Gentlemen:
 
     I may presently be considered to be an "affiliate", as defined in paragraph
(a) of Rule 144 of the Rules and Regulations of the Securities and Exchange
Commission ("SEC") under the Securities Act of 1933, as amended (the "Act"), of
The Citizens National Bancshares, Inc., Hope, Arkansas, a bank holding company
("Citizens"). Pursuant to the merger (the "Merger") of Citizens with and into a
subsidiary of First United Bancshares, Inc. ("First United"), I will acquire
       shares of the common stock, par value $1 per share ("Common Stock"), of
First United . I represent and warrant that I (i) am acquiring said shares (as
the same may be increased, decreased or are changed in accordance with the
Agreement and Plan of Merger dated             , 1997, relating to the Merger,
the ("Shares")) for my own account (or in the capacity indicated hereon) and
with no present intention of dividing my participation with others or otherwise
making a distribution of the Shares and (ii) shall not make any sale, transfer
or other disposition of the Shares in violation of the Act or the General Rules
and Regulations promulgated thereunder by the SEC.
 
     I have been advised that the Shares issued to me pursuant to the Merger
have been registered under the Act in the Registration Statement on SEC Form
S-4, as amended, Registration No.        ("Registration Statement") as filed
with the SEC, and have received a copy of the proxy/prospectus filed as a part
of the Registration Statement. However, I have also been advised that any public
offering or sale by me of any of the Shares will, under current law, require
either (i) the further registration (by amendment of such Form S-4 or otherwise)
under the Act of the Shares to be sold or (ii) compliance with Rule 145
promulgated under the Act or (iii) the availability of another exemption from
such registration.
 
     I agree not to sell, transfer or dispose of the Shares unless (i) there is
in effect a registration statement under the Act covering such sale, transfer,
or other disposition, or (ii), such sale, transfer or disposition complies with
Rule 145 or is otherwise exempt from registration. Further, I will furnish to
First United such documentation incident to such sale, transfer or other
disposition as First United shall reasonably request evidencing compliance with
Rule 145 or the availability of any exemption from registration being claimed.
Such documentation shall be provided to First United prior to any such sale,
transfer or other disposition in order that First United, and its counsel may
have a reasonable opportunity to review the documentation and form an opinion as
to the validity of any such exemption.
 
     I agree that notwithstanding any provision herein or contained in the
Agreement and Plan of Reorganization that I will not sell, transfer, or
otherwise dispose of any of the Shares unless First United has made public
disclosure of financial results reflecting 30 days' of post-Merger combined
operations of Citizens and First United within the meaning of Section 201.01 of
the SEC's Codification of Financial Reporting Policies. First United has agreed
to make the required public disclosure of financial results as set out above as
soon as feasible after the Merger is consummated. In addition, I hereby
represent and warrant to First United that I have not made any sales of Citizens
or First United common stock during the 30-day period immediately preceding the
date hereof and I further agree not to engage in any such sales prior to the
Merger, nor have I pledged or will I pledge any First United or Citizens common
stock to secure any obligation during such period.
 
     I represent and warrant to First United that:
 
          1. I have carefully read this letter and discussed its requirements
     and other applicable limitations upon the sale, transfer or other
     disposition of the Shares, to the extent I felt necessary, with my counsel
     or counsel for Citizens.
 
          2. I have been informed by First United that any distribution by me of
     the Shares has not been registered under the Act and that the Shares must
     be held by me indefinitely until (i) such distribution of the Shares has
     been registered under the Act, (ii) a sale of the Shares is made in
     conformity with the
 
                                     A-I-33
<PAGE>   107
 
     volume and other limitations of Rule 145 promulgated by the SEC under the
     Act, or (iii) some other exemption from registration is available with
     respect to any such proposed sale, transfer or other disposition of the
     Shares.
 
          3. I have been informed by First United that it is required to file
     periodic reports with the SEC and the NASDAQ and that certain sales of the
     Shares by me may not be required to be registered under the Act by virtue
     of Rule 145 promulgated by the SEC under the Act, provided that such sales
     are made in accordance with all of the terms and conditions of such Rule,
     including among other things the following:
 
             (a) The amount of First United Common Stock sold by me pursuant to
        Rule 145 during any period of three months cannot exceed the quantity
        limit of (i) one percent of the total outstanding First United Common
        Stock or (ii) the average reported weekly trading volume on NASDAQ
        during the four week period immediately preceding receipt of the order
        by the broker to execute the transaction, whichever of (i) or (ii) is
        greater. In computing the quantity limit it is necessary to count sales
        not only by me but also by certain immediate family members and other
        related persons and others with whom I may act in concert.
 
             (b) Sales must be made in brokers' transactions as defined by the
        SEC Rule 144 (certain provisions of which are incorporated by reference
        into Rule 145).
 
             (c) No sales may be made under the Rule unless First United has
        filed all SEC reports required to be filed by First United.
 
             (d) The broker must be given information showing compliance with
        Rule 145.
 
          4. I understand that First United is under no obligation to register
     the sale, transfer or other disposition of the Shares by me or on my behalf
     or to take any other action necessary in order to make compliance with an
     exemption from registration available.
 
          5. I understand and agree that stop transfer instructions will be
     issued with respect to the Shares and there will be placed on the
     certificates representing such Shares, or any certificate delivered in
     substitution therefor, a legend stating in substance:
 
             "The shares represented by this Certificate were issued in a
        transaction to which Rule 145 under the Securities Act of 1933, as
        amended, applied. The shares represented by this certificate may be
        transferred only in accordance with the terms of a letter agreement
        dated             , 1997, by the registered holder in favor of First
        United Bancshares, Inc., a copy of which agreement is on file at the
        principal offices of First United Bancshares, Inc."
 
     I have been informed by First United that after the restrictions imposed by
     Rule 145 have expired First United will, upon my request, reissue share
     certificates for the shares which do not contain a restrictive legend.
 
          6. I understand and agree that unless the transfer by me of Shares is
     a sale made in compliance with the provisions of this letter, First United
     reserves the right to place the following legend on any certificates issued
     to my transferee:
 
             "The shares represented by this Certificate have not been
        registered under the Securities Act of 1933, as amended, and were
        acquired from a person who received such shares in a transaction to
        which Rule 145 under the Securities Act of 1933, as amended, applied.
        The shares have not been acquired by the holder with a view to, or for
        resale in connection with, any distribution thereof within the meaning
        of the Securities Act of 1933, as amended, and may not be sold, pledged
        otherwise transferred unless the shares have been registered under the
        Securities Act of 1933, as amended, or an exemption from registration is
        available."
 
          7. I understand and agree that the legends set forth in paragraphs 5
     and 6 above shall be removed by delivery of substitute Certificates without
     any legend if I deliver to First United a copy of a letter from the staff
     of the Commission, or an opinion of counsel in form and substance
     reasonably satisfactory to First United, to the effect that no such legend
     is required for the purpose of the Securities Act.

          8. I have been informed by First United that if I propose to sell any
     of these Shares pursuant to Rule 145, and if such sale would be permitted
     under the terms of this letter, First United will, upon my written request,
     supply me with the following:
 
             (a) A statement as to whether First United has complied with the
        provisions of Rule 145 regarding filing of SEC reports as a condition to
        sales made pursuant to that Rule;
 
             (b) A confirmation as to the number of shares of First United
        Common Stock outstanding as shown by the most recent report or statement
        published by it; and
 
             (c) First United's taxpayer identification number and SEC file
        number.
 
     I have carefully read this letter and have had an adequate opportunity to
review the Merger Agreement and understand the requirements and the limitations
imposed upon the distribution, sale, transfer or other disposition of Bank
common stock or Shares of First United.
 
                                            Very truly yours,

     requirements of sec.sec. 4-27-1320 -- 4-27-1328; 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 chapter.
 
     C. If the court finds that the services of counsel 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 counsel reasonable fees to be paid out of the amounts awarded the
dissenters who were benefited.

                               September 22, 1997
 
Members of the Board of Directors
Citizens National Bancshares, Inc.
200 S. Elm Street
Hope, Arkansas 71802
 
Members of the Board:
 
     You have requested our opinion as investment bankers as to the fairness,
from a financial point of view, to the shareholders of Citizens National
Bancshares, Inc., Hope, Arkansas ("Citizens") of the terms of the proposed
merger of Citizens with and into First United Bancshares, Inc., El Dorado,
Arkansas ("First United") as defined in the Agreement and Plan of
Reorganization, dated as of September 15, 1997 (the "Agreement"). Pursuant to
the Agreement and subject to the terms and conditions therein, the purchase
price paid by First United to the owners of Citizens Common Stock shall be One
Million Five Hundred and Seventy Thousand (1,570,000) shares of First United
Common Stock.
 
     As part of its investment banking business, Hoefer & Arnett, Incorporated
is continually engaged in the valuation of bank, bank holding company and thrift
securities in connection with mergers and acquisitions nationwide. We have not
previously provided investment banking and financial advisory services to
Citizens.
 
     In arriving at our opinion, we have reviewed and analyzed, among other
things, the following: (i) the Agreement; (ii) Annual Reports to Shareholders of
Citizens and First United for the years ended December 31, 1995 and December 31,
1996; (iii) Quarterly FDIC call reports for the quarters ended June 30, 1997,
March 31, 1997, December 31, 1996, September 30, 1996 and June 30, 1996; (iv)
certain other publicly available financial and other information concerning
Citizens and First United; (v) the historical market prices and trading activity
for the common stock of First United; and (vi) publicly available information
concerning other banks and holding companies, the trading markets for their
securities and the nature and terms of certain other merger transactions we
believe relevant to our inquiry. We have held discussions with senior management
of Citizens and First United concerning their past and current operations,
financial condition and prospects, as well as the results of regulatory
examinations.
 
     We have reviewed with senior management of First United earnings
projections for 1997 through 2001 for First United as a stand-alone entity,
assuming the merger does not occur. We reviewed with senior management of
Citizens earnings projections for 1997 through 2001 as a stand-alone entity,
assuming the merger does not occur. Certain pro forma financial projections for
the years 1997 through 2001 for the combined entity were derived by us based
partially upon the projections discussed above, as well as our own assessment of
general economic, market and financial conditions. In certain cases, such
combined pro forma financial projections included projected operating cost
savings derived by us partially based upon the projections discussed above to be
realizable in the merger.
 
     In conducting our review and in arriving at our opinion, we have relied
upon and assumed the accuracy and completeness of the financial and other
information provided to us or publicly available, and we have not assumed any
responsibility for independent verification of the same. We have relied upon the
managements of Citizens and First United as to the reasonableness of the
financial and operating forecasts, projections and projected operating cost
savings (and the assumptions and bases therefor) provided to us, and we have
assumed that such forecasts, projections and projected operating cost savings
reflect the best currently available estimates and judgments of the applicable
managements. We have also assumed, without assuming any responsibility for the
independent verification of the same, that the aggregate allowance for loan
losses for Citizens and First United are adequate to cover such losses. We have
not made or obtained any evaluations or appraisals of the property of Citizens
or First United, nor have we examined any individual loan credit files. For
purposes of this opinion, we have assumed that the merger will have the tax,
accounting and legal effects described in the Agreement and assumed the accuracy
of the disclosures set forth in the Agreement. Our opinion as expressed herein
is limited to the fairness, from a financial point of view, to the holders of
the
 
                                     A-IV-1
<PAGE>   117
 
Common Shares of Citizens of the terms of the proposed merger of Citizens with
and into First United and does not address Citizens' underlying business
decision to proceed with the merger.
 
     We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following: (i)
the historical and current financial position and results of operations of
Citizens and First United, including interest income, interest expense, net
interest income, net interest margin, provision for loan losses, non-interest
income, non-interest expense, earnings, dividends, internal capital generation,
book value, intangible assets, return on assets, return on shareholders' equity,
capitalization, the amount and type of nonperforming assets, loan losses and the
reserve for loan losses, all as set forth in the financial statements for
Citizens and First United; (ii) the assets and liabilities of Citizens and First
United, including the loan, investment and mortgage portfolios, deposits, other
liabilities, historical and current liability sources and costs and liquidity;
and (iii) the nature and terms of certain other merger transactions involving
banks and bank holding companies. We have also taken into account our assessment
of general economic, market and financial conditions and our experience in other
transactions, as well as our experience in securities valuation and our
knowledge of the banking industry generally. Our opinion is necessarily based
upon conditions as they exist and can be evaluated on the date hereof and the
information made available to us through the date hereof.
 
     Based upon and subject to the foregoing, we are of the opinion as
investment bankers that, as of the date hereof, the terms of proposed merger of
Citizens with and into First United are fair, from a financial point of view, to
the holders of the Common Shares of Citizens.
 
     It is understood that this letter is for the information of the Board of
Directors of Citizens and does not constitute a recommendation to the Board of
Directors or to any shareholder of Citizens with respect to any approval of the
merger. We hereby consent to the reference to our firm in the proxy statement or
prospectus related to the merger transaction and to the inclusion of our opinion
as an exhibit to the proxy statement or prospectus related to the merger
transaction.
 
                                            Very truly yours,
 
                                            /s/ HOEFER & ARNETT, INCORPORATED
                                            Hoefer & Arnett, Incorporated

                                    PART II
 
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Arkansas Business Corporation Act of 1987 (the "Act") codified at Ark.
Code Ann. sec.4-27-101 et. seq.and more specifically at Ark. Code Ann.
sec.4-27-850 permits an Arkansas Corporation to indemnify directors, officers,
employees and agents under some circumstances, and mandates indemnification
under certain limited circumstances. The Act permits a corporation to indemnify
a director, officer, employee, or agent for expenses (including attorneys'
fees), judgements, fines and amounts paid in settlement actually and reasonably
incurred if such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation.
Indemnification against expenses incurred by a director, officer, employee or
agent in connection with his defense of a proceeding against such person for
actions in such capacity is mandatory to the extent that such person has been
successful on the merits. If a director, officer, employee, or agent is
determined to be liable to the corporation, indemnification for expenses is not
allowable, subject to limited exceptions where a court deems the award of
expenses appropriate. The Act grants express power to an Arkansas corporation to
purchase liability insurance for its directors, officers, employees and agents,
regardless of whether any such person is otherwise eligible for indemnification
by the corporation. Advancement of expenses is permitted, but a person receiving
such advances must repay those expenses if it is ultimately determined that he
is not entitled to indemnifications.
 
     The Amended and Restated Articles of Incorporation and the Bylaws of First
United provides that the directors, officers, employees and agents of First
United shall be indemnified as set forth below.
 
                 AMENDED AND RESTATED ARTICLES OF INCORPORATION
 
     Twelfth. The corporation may indemnify any person who was, or is, a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding to the fullest extent permitted by the Arkansas
Business Corporation Act as it now exists or may hereafter be amended.
 
                                    BY-LAWS
 
     Article VII, Section 6. Indemnification. Every person who was or is a party
or is threatened to be made a party to or is involved in any action, suit,
proceeding, whether civil, criminal, administrative, or investigative, by reason
of the fact that he is or was a director or officer of the Corporation or is or
was serving at the request of the Corporation as a director or officer of
another corporation, or as its representative in a partnership, joint venture,
trust, or other enterprise, shall be indemnified and held harmless to the
fullest extent legally permissible under and pursuant to any procedure specified
in the Arkansas Business Corporation Act of the State of Arkansas, as amended
and as the same may be amended hereafter, against all expenses, liabilities, and
losses (including attorney's fees, judgments, fines and amounts paid or to be
paid in settlement) reasonably incurred or suffered by him in connection
therewith. Such right of indemnification shall be a contract right that may be
enforced in any lawful manner by such person. Such right of indemnification
shall not be exclusive of any other right which such director or officer may
have or hereafter acquire and, without limiting the generality of such
statement, he shall be entitled to his rights of indemnification under any
agreement, vote of stockholders, provisions of law, or otherwise, as well as his
rights under this paragraph.
 
     The board of directors may cause the Corporation to purchase and maintain
insurance on behalf of any person who is or was a Director or officer of the
Corporation, or is or was serving at the request of the Corporation as a
director or officer of another corporation, or as its representative in a
partnership, joint venture, trust or other enterprise against any liability
asserted against such person and incurred in any such capacity or arising out of
such status, whether or not the Corporation would have power to indemnify such
person.

ITEM 22. UNDERTAKINGS
 
     (1) 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.
 
     (2) 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.
 
     (3) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (3) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (4) 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
 
                                      II-2
<PAGE>   120
 
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of 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.
 
     (5) 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.
 
     (6) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of 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.
 
     (7) The undersigned registrant hereby undertakes:
 
          (a) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement.
 
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
          Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
     apply if the registration statement is on Form S-3 (sec.239.13 of this
     chapter) or Form S-8 (sec.239.16b of this chapter), and the information
     required to be included in a post-effective amendment by those paragraphs
     is contained in periodic reports filed by the registrant pursuant to
     section 13 or section 15(d) of the Securities Exchange Act of 1934 that are
     incorporated by reference in this registration statement.
 
          (b) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (c) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

(the "Act") of 1,570,000 shares (the "Securities") of Common Stock, $1.00 par
value, of First United Bancshares, Inc., an Arkansas corporation (the
"Company"), we, as your special counsel, have examined such corporate records,
certificates and other documents, and such questions of law, as we have
considered necessary or appropriate for the purposes of this opinion.  Upon the
basis of such examination, we advise you that, in our opinion, when the

Securities have been duly established in conformity with the Company's articles
of incorporation, and the Securities have been duly issued and sold as
contemplated by the Registration Statement and upon consummation of the merger
of Citizens National Bancshares of Hope, Inc. with and into the Company, the
Securities will be validly issued, fully paid and nonassessable.

         The foregoing opinion is limited to the Federal laws of the United
States and the laws of the State of Arkansas, and we are expressing no opinion
as to the effect of the laws of any other jurisdiction.

         We have relied as to certain matters on information obtained from
public officials, officers of the Company and other sources believed by us to
be responsible.

         We hereby consent to the filing of this opinion as an exhibit to the

                    [LETTERHEAD OF FRIDAY, ELDREDGE & CLARK]

Mr. John Robert Graves
Citizens National Bancshares, Inc.
200 South Elm Street
Hope, AR 72801

         Re:   Merger of Citizens National Bancshares, Inc. with and into
               First United Bancshares, Inc.

Gentlemen:

         You have asked for our opinion regarding certain federal income tax
consequences in connection with the proposed merger of Citizens National
Bancshares, Inc. (Citizens"), an Arkansas corporation, with and into First
United Bancshares, Inc. ("Bancshares"), an Arkansas corporation, pursuant to an
Agreement and Plan of Reorganization dated as of September 15, 1997 (the
"Merger Agreement").  This opinion is being delivered pursuant to Section
7.03(e) of the Merger Agreement.  Capitalized terms not otherwise defined in
this opinion shall have then meaning ascribed to such term under the Merger
Agreement.

         This opinion is based upon the following factual assumptions:

         (a)     Bancshares and Citizens are engaged in the business of
operating as bank holding companies under the laws of the State of Arkansas and
the federal laws of the United States.

         (b)     Upon the effective date of the merger, the shareholders of
Citizens (other than Citizens shareholders who exercise dissenters' rights
under applicable state law), will receive their pro rata share of 1,570,000
shares of Bancshares voting common stock in exchange for their respective
outstanding shares of Citizens common stock.  Bancshares will make a cash
payment to shareholders of Citizens in lieu of issuing fractional shares of
Bancshares common stock based upon the Bancshares Average Price as
of the Effective Time of the Merger.  Citizens shares of common stock having a
value equal to at least fifty percent (50%) of the value of the outstanding
shares of Citizens common stock shall be exchanged in the merger solely for
Bancshares common stock.

         (c)     Citizens presently has, and within the last three (3) years
has had, only one class of capital stock outstanding, all of which is common
stock having a par value of $2.00 per share.

         (d)     Citizens will be merged with and into Bancshares pursuant to
laws of the State of Arkansas and the separate existence of Citizens shall
cease and Bancshares shall continue as the surviving corporation with all the
assets and liabilities of Citizens and Bancshares combined.  Bancshares will
continue to carry on the business previously conducted by it.

         (e)     The Bancshares common stock to be received by the Citizens
shareholders in connection with the merger will be voting common stock with all
of the rights normally accorded to Bancshares common stockholders.





<PAGE>   2


         (f)     The merger is being consummated for valid business reasons
germane to the business of the parties, separate and apart from tax purposes.

         (g)     The fair market value of the Bancshares common stock to be
received by each Citizens shareholder will be approximately equal to the fair
market value of the Citizens stock surrendered in the exchange.

         (h)     There is no plan or intention by the shareholders of Citizens
to sell, exchange, or otherwise dispose of a number of shares of Bancshares
common stock received in the transaction that would reduce the Citizens
shareholders' ownership of Bancshares stock to a number of shares having a
value, as of the date of the transaction, of less than 50% of the value of all
of the outstanding stock of Citizens as of the same date.  For purposes of this
assumption, shares of Citizens stock exchanged for cash or other property,
surrendered by dissenters, or exchanged for cash in lieu of fractional shares
of Bancshares stock, will be treated as outstanding Citizens stock on the date
of the transaction.  Moreover, shares of Citizens stock and shares of
Bancshares stock held by Citizens shareholders and otherwise sold, redeemed, or
disposed of prior or subsequent to the transaction will be considered in making
this assumption.  There will have been no transfers, in the aggregate, of more
than fifty percent (50%) of the value of the Citizens stock prior to the
effective date of the merger which were made in contemplation of the merger.

         (i)     Bancshares has no plan or intention to reacquire any of its
stock issued in the transaction.

         (j)     Bancshares has no plan or intention to sell or otherwise
dispose of any of the assets of Citizens acquired in the transaction, except
for dispositions made in the ordinary course of business or transfers described
in I.R.C. Section  368(a)(2)(C).

         (k)     The liabilities of Citizens assumed by Bancshares and the
liabilities to which the transferred assets of Citizens are subject were
incurred by Citizens in the ordinary course of its business.  The assumption by
Bancshares of the liabilities of Citizens pursuant to the merger will be for a
bona fide business purpose and not for the purpose of avoiding federal income
tax.  No liabilities of any  person other than Citizens shall be assumed by
Bancshares in the merger, and none of the shares of Citizens stock surrendered
in the merger in exchange for Bancshares stock will be subject to any
liabilities.

         (l)     Following the transaction, Bancshares will continue the
historic business of Citizens or use a significant portion of Citizens's
historic business assets in a business.

         (m)     Bancshares, Citizens and the shareholders of Citizens will pay
their respective expenses, if any, incurred in connection with the transaction.

         (n)     There is no intercorporate indebtedness existing between
Bancshares and Citizens that was issued, acquired, or will be settled at a
discount.

         (o)     No two parties to the transaction are investment companies as
defined in I.R.C. Section 368(a)(2)(F)(iii) and (iv).

         (p)     Citizens is not under the jurisdiction of a court pursuant to
a case under Title XI of the United States Code, or a receivership,
foreclosure, or other similar proceeding in a federal or state court.

         (q)     The fair market value of the assets of Citizens transferred to
Bancshares will exceed the sum of the liabilities assumed by Bancshares, plus
the amount of liabilities, if any, to which the transferred assets are subject.

         (r)     No fractional share interests in Bancshares common stock will
be issued in connection with the transaction.  The payment of cash in lieu of
fractional shares of Bancshares common stock is solely for the purpose of
avoiding the expense and inconvenience to Bancshares of issuing fractional
shares and does not represent separately bargained-for consideration.

         (s)     None of the compensation received by any shareholder-employee
of Citizens will be separate consideration for, or allocable to, any of his or
her shares of Citizens stock.





<PAGE>   3


         (t)     None of the shares of Bancshares stock received by any
shareholder-employee of Citizens will be separate consideration for, or
allocable to, any employment agreement, and the compensation paid to any
shareholder-employee will be for services actually rendered and will be
commensurate with the amounts paid to third parties bargaining at arm's length
for similar services.

         Based upon the foregoing factual representations and assumptions, and
subject to the comments and qualifications expressed herein, we are of the
opinion that:

                 1.       The proposed merger will constitute a reorganization
with the meaning of I.R.C. Section 368(a)(1)(A).

                 2.       Citizens and Bancshares will each be "a party to a
reorganization" within the meaning of I.R.C. Section  368(b).

                 3.       No gain or loss will be recognized by Citizens on the
transfer of its assets to Bancshares in exchange for Bancshares common stock
and the assumption by Bancshares of the liabilities, if any, of Citizens.
I.R.C.  Sections 357(a) and 361(a).

                 4.       No gain or loss will be recognized by Bancshares upon
the receipt of the assets of Citizens in exchange for Bancshares common stock.
I.R.C. Section 1032(a).

                 5.       The basis of the assets of Citizens acquired by
Bancshares will be the same in the hands of Bancshares as the basis of such
assets in the hands of Citizens immediately prior to the exchange.  I.R.C.
Section 362(b).

                 6.       The holding period of the assets of Citizens in the
hands of Bancshares will, in each instance, include the period for which such
assets were held by Citizens.  I.R.C. Section 1223(2).

                 7.       No gain or loss will be recognized by the
shareholders of Citizens upon the exchange of Citizens common stock solely for
Bancshares common stock.  I.R.C. Section 354(a)(1).

                 8.       The basis of the Bancshares common stock received by
the shareholders of Citizens will be the same as the basis of the Citizens
stock surrendered in exchange therefor.  I.R.C. Section 358(a)(1).

                 9.       The holding period of the Bancshares common stock
received by the shareholders of Citizens will include the period during which
the Citizens stock surrendered in exchange therefor was held, provided the
stock of Citizens is a capital asset in the hands of the shareholders of
Citizens on the date of the exchange.  I.R.C. Section 1223(1).

                 10.      Where a shareholder of Citizens dissents to the
proposed transaction and receives solely cash in exchange for his stock, such
cash will be treated as having been received by the shareholder as a
distribution in redemption of such shareholder's stock subject to the
provisions and limitations of I.R.C. Section 302. Rev. Rul. 74-515, 1974-2
C.B. 118.

                 11.      The payment of cash to Citizens shareholders in lieu
of fractional share interests of Bancshares common stock will be treated as if
the fractional shares were distributed as part of the exchange and then
redeemed by Bancshares.  These cash payments will be treated as having been
received as distributions in full payment in exchange for the stock redeemed
subject to the provisions and limitations of I.R.C. Section 302.  Rev. Rul.
66-365, 1966-2 C.B. 116 and Rev. Proc. 77-41, 1977-2 C.B. 574.

         The opinions expressed herein are subject to the following
qualifications:

                 (i)      We have assumed that the express written terms of the
Merger Agreement set forth the entire agreement of the parties with respect to
the proposed transaction, and that there are no oral or written statements,
representations, agreements, or understandings which modify, amend, or vary any
of the terms thereof.





<PAGE>   4


                 (ii)     This opinion is limited to the matters expressly set
forth herein, and no opinion may be implied or inferred beyond the specific
language and scope so stated.

                 (iii)    The opinions expressed above regarding tax-free
reorganization treatment of the merger assume that the Citizens shareholders
have, and will continue following the merger to maintain, a "continuity of
interest" in the business of the Citizens, directly through the ownership of
Citizens stock prior to the merger, and indirectly through the ownership of
Bancshares common stock following the merger.  For this purpose, a "continuity
of interest" shall mean the ownership of stock having a value, as of the date
of the transaction, of 50% or more of the value of all of the formerly
outstanding stock of Citizens on such date.

                 (iv)     This opinion is based upon the factual assumptions
and representations described herein.  Accordingly, we shall have no liability
in rendering this opinion to the extent it is adversely affected by reason of
any such factual assumptions or representations being false or incorrect.

                 (v)      This opinion is rendered as of the date hereof and is
based upon the current version of the Internal Revenue Code, regulations
promulgated thereunder, current rulings of the Internal Revenue Service and
applicable case law, and, accordingly, is subject to any changes in such law,
regulations, rulings, or judicial decisions occurring after the date of this
opinion.

                 (vi)     This opinion is provided solely for the benefit of
Citizens and the shareholders of Citizens and may not be relied upon by any
other person or entity, quoted in whole or in part, filed with any governmental
agency, or otherwise referred to or utilized for any other purpose, without, in
each instance, or prior written consent.  We consent to the use and filing of
this opinion in connection with filings to be made with the Federal Reserve
Board and Securities and Exchange Commission concerning this transaction and in
connection with the disclosure documents to Citizens shareholders with respect
to the proposed transaction.  In addition, we specifically consent to the use
of this opinion as an exhibit to Bancshares's Registration Statement on Form
S-4 which is being filed to register the shares of Bancshares common stock to
be issued in the proposed transaction, as it may be amended, and consent to
such references to our firm as are made therein.

             (vii)        This opinion is being furnished as of the date hereof
and we have no obligation or duty to update or supplement this opinion by
reason of events or changes in applicable law occurring after the date of this
letter.

                               Very truly yours,



                               FRIDAY, ELDREDGE & CLARK
