                         FIRST UNITED BANCSHARES, INC.
 
To the Stockholders of
First United Bancshares, Inc.
 
     Enclosed is a Notice of Special Meeting of Stockholders of First United
Bancshares, Inc. ("First United") which will be held at the main office of First
National Bank of El Dorado at Main and Washington Streets, El Dorado, Arkansas
on June 13, 1994 at 2:00 P.M.
 
     At a Special Meeting, Stockholders of First United will consider and vote
upon the merger of First United and InvestArk Bankshares, Inc. ("InvestArk")
whereby InvestArk will be merged with and into First United. The Agreement
between First United and InvestArk provides that the stockholders of InvestArk
will receive total consideration of $26,125,000 consisting of fully paid and
nonassessable shares of Common Stock, $1.00 par value of First United, if the
average price of First United Common Stock is between $26.50 and $29.50. If the
average price is in this range the number of shares of First United common stock
to be exchanged for all of the issued and outstanding shares of InvestArk Common
Stock will be determined by dividing $26,125,000 by the average price 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. Notwithstanding the foregoing, the number of shares of First United Common
Stock to be exchanged shall not be less than 885,593 and shall not be greater
than 985,849 which equate to an average price of First United Common Stock of
$29.50 and $26.50, respectively.
 
     If the average price of First United common stock is less than $26.50, the
amount of shares issued shall equal the ceiling of 985,849 shares. Also, if the
average price of First United common stock is more than $29.50, the amount of
shares issued shall equal the floor of 885,593 shares. The total consideration
exchanged will vary from $26,125,00 if the average price is either higher than
$29.50 or lower than $26.50. For example, if the average price is $35.00, the
InvestArk stockholders shall receive 885,593 shares of First United common
stock, each share having a value of $35.00 representing total consideration of
$30,995,755. If the average price is $22.00, the InvestArk stockholders shall
receive 985,849 shares of First United common stock, each having a value of
$22.00 representing a total of $21,688,678.
 
     InvestArk is a bank holding company which is primarily engaged in the
business of banking through its two wholly-owned bank subsidiaries, with branch
offices in Izard and Arkansas counties which provide a full range of banking
services to its customers.
 
     The Board of Directors believes that the proposed merger upon the terms and
conditions set forth in the accompanying Proxy Statement is in the best
interests of our Stockholders and therefore recommends that you vote in favor of
the merger. Additional information regarding the proposed merger, InvestArk and
the rights of dissenting Stockholders is set forth in the enclosed Proxy
Statement and I urge you to read this material carefully.
 
     You are cordially invited to attend the meeting in person. Whether or not
you plan to attend the Special Meeting, please sign, date and return as soon as

                                    SUMMARY
 
     The following is a summary of certain information contained elsewhere in
this Proxy Statement. Reference is made to, and this summary is qualified in its
entirety by, the more detailed information contained elsewhere in this Proxy
Statement, in the attached Annexes and in the documents incorporated by
reference. Stockholders are urged to read carefully this Proxy Statement and the
attached Annexes in their entirety.
 
THE COMPANY
 
     The Company is a multi-bank holding company located in El Dorado, Arkansas
with five wholly-owned subsidiary banks operating in over 28 locations in seven
communities throughout the State of Arkansas. The Company's subsidiary banks
consist of First National Bank of El Dorado, El Dorado, Arkansas; First National
Bank of Magnolia, Magnolia, Arkansas; City National Bank of Fort Smith, Fort
Smith, Arkansas; Merchants and Planters Bank, N.A., Camden, Arkansas; and
Commercial Bank at Alma, Alma, Arkansas (collectively called the "Subsidiary
Banks"). The Company had consolidated assets of $938,694,000, and stockholders'
equity of $91,257,000 as of December 31, 1993.
 
     The Company's Common Stock is traded on the National Association of
Securities Dealers Automated Quotation National Market System Over-the-Counter
Market (NASDAQ-NMS) under the symbol "UNTD". The Company's principal executive
offices are located at Main and Washington Streets, El Dorado, Arkansas, 71730,
and its telephone number is (501) 863-3181.
 
INVESTARK
 
     InvestArk is a privately-owned Arkansas bank holding company which owns
99.7% of Bank of North Arkansas, Melbourne, Arkansas ("North Arkansas") and 100%
of First Stuttgart Bank and Trust Company, Stuttgart, Arkansas ("First Bank").
InvestArk had consolidated assets of $184,904,000 and stockholders' equity of
$16,865,000 as of December 31, 1993.
 
     There is no public market for shares of InvestArk's outstanding capital
stock. InvestArk's principal executive offices are located at 412 South Main
Street, Stuttgart, Arkansas, 72021; its telephone number is (501) 673-3545.
 
FEDERAL RESERVE BOARD INVESTIGATIONS
 
     On March 4, 1993, the Board of Governors of the Federal Reserve System
commenced a formal investigation of the ownership and control of Worthen Banking
Corporation ("Worthen"). The investigation appears to be focused on whether
members of the families of Jackson T. Stephens and Wilton R. Stephens (deceased)
have exerted control over Worthen in violation of the Bank Holding Company Act
and the Change in Bank Control Act. The events and transactions which are the
subject of the investigation do not involve InvestArk or First United. The
investigation is still ongoing. See "InvestArk Bankshares, Inc. -- Federal
Reserve Board Investigations."
 
     In addition, in February 1993, InvestArk management was advised that the
Federal Reserve Bank of St. Louis (the "St. Louis FED") had initiated a review
of the purchase and sale of municipal and other securities by and between
Stephens Inc., a registered broker-dealer owned by the Stephens family, and
InvestArk's bank subsidiaries to determine whether the transactions violated the
prohibitions of Section 23A and 23B of the Federal Reserve Act. First United's
obligation to consummate the Merger is conditioned upon the St. Louis FED not
having notified either of the parties of actual or proposed regulatory action
having an adverse effect on First United, InvestArk or the InvestArk bank
subsidiaries. See "InvestArk Bankshares, Inc. -- Federal Reserve Board
Investigations."
 
THE MERGER
 
     On December 17, 1993, the Company and InvestArk entered into a definitive
agreement pursuant to which the Company proposes to acquire all of the issued
and outstanding stock of InvestArk by merger of InvestArk with and into First
United. The acquisition of InvestArk will be consummated through the issuance
 
                                        6
<PAGE>   11
 
to InvestArk's stockholders of up to 985,849 shares of First United Common
Stock. The reason for the Merger is to expand the markets of the Company and
thereby increase the earning potential of the Company. The Agreement requires
that the merger be accounted for as a pooling of interests. See "The
Merger -- The Agreement."
 
     On October 21, 1993, the date immediately prior to the announcement of the
agreement in principle, shares of First United Common Stock traded on the
NASDAQ-NMS at a closing sales price of $29.50. There is no established market
value for the stock of InvestArk.
 
     Stephens Inc., a registered broker-dealer, served as a financial adviser to
InvestArk with respect to the Merger. For its role, Stephens Inc. is to receive
a $100,000 cash payment plus reasonable expenses from InvestArk. Stephens Inc.
is controlled by certain members of the families of Jackson T. Stephens and
Wilton R. Stephens (deceased) who are also affiliates of InvestArk. There are no
other benefits, other than the benefit of share ownership and/or continued
employment, to be received by insiders, officers, directors, affiliates or
principal stockholders of either InvestArk or First United as a result of the
Merger.
 
     THE BOARD OF DIRECTORS OF FIRST UNITED AND INVESTARK UNANIMOUSLY RECOMMEND
THAT FIRST UNITED AND INVESTARK STOCKHOLDERS, RESPECTIVELY, VOTE IN FAVOR OF THE
ADOPTION OF THE AGREEMENT.
 
COMBINED COMPANY
 
     As a result of the Merger, the combined operations and its constituent
parts of First United and InvestArk as of December 31, 1993 and for the year
then ended will reflect assets, shareholders' equity, net interest income and
income from continuing operations as follows (in thousands):

     If the maximum of 985,849 shares of common stock of First United are issued
to InvestArk stockholders, First United will have a total of 5,258,125 shares of
common stock issued and outstanding. Present First United stockholders will
control 81.25% of such shares and InvestArk stockholders will control 18.75% of
such shares. Approximately two-thirds of all shares issued to InvestArk
stockholders will be issued to members of the Stephens family. Pursuant to an
agreement with the Board of Governors of the Federal Reserve System, these
shares will be placed in trust and the voting power over such shares shall be
exercised by the trustee, who shall vote such shares equal to the percentages of
affirmative and negative votes of all other shares on any matter presented to
stockholders. The W. R. Stephens Trust and the W. R. Stephens, Jr. Trust
presently own approximately 3.95% of all issued and outstanding shares of First
United common stock and these shares will continue to be voted by their
respective trustees. See "InvestArk Bankshares, Inc. -- Resulting Ownership in
First United."
 
NO FAIRNESS OPINION
 
     No fairness opinion will be rendered in connection with this transaction.
 
ELECTION BY INVESTARK STOCKHOLDERS UNDER THE 1987 ACT
 
     The Election by the stockholders of InvestArk to be governed by the
Arkansas Business Corporation Act of 1987 codified at Ark. Code Ann. sec.
4-27-101 et. seq. (the "1987 Act") is incidental to and a condition of the
Merger proposal and approval of such election will have no force or effect
unless the Merger is likewise approved.
 
                                        7
<PAGE>   12
 
     InvestArk is a corporation organized under the Arkansas Business
Corporation Act of 1965, codified at 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 stockholders of First United elected to be governed by the 1987
Act by amending its Articles of Incorporation.
 
     The 1965 Act and 1987 Act have statutory merger procedures that must be
complied with in order to legally consummate a merger. Although both Acts
contain similar provisions, InvestArk 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 June 13, 1994 at 2:00 p.m. Central Daylight 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. Directors,
executive officers and their affiliates hold a total of approximately 26.50% of
the outstanding Common Stock of First United. Stockholders of First United are
entitled to dissenters' rights. See "The Merger -- Right of Dissent under the
1987 Act."
 
THE INVESTARK SPECIAL MEETING
 
     Approval of the Merger by the stockholders of InvestArk will be considered
at a Special Meeting to be held at 412 South Main Street, Stuttgart, Arkansas on
June 13, 1994, at 10:00 a.m. Central Daylight Time.
 
     The affirmative vote of the holders of a two-thirds of the outstanding
shares of InvestArk common stock is required for the approval of the Merger and
the Election to be governed by the 1987 Act. Directors, executive officers and
their affiliates hold a total of 6.30% of the outstanding stock of InvestArk. In
addition, stockholders who in the aggregate own 66.14% of the issued and
outstanding shares of InvestArk common stock have contractually committed to
vote their shares in favor of the Merger. Stockholders of InvestArk 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 InvestArk as a result of the Merger and InvestArk's stockholders will not
recognize gain or loss upon the receipt of First United Common Stock in exchange
for InvestArk common stock. InvestArk expects to receive an opinion of counsel,
dated as of the effective date of the Merger, opining that no gain or loss will
be recognized by the InvestArk stockholders upon the receipt of First United
Common Stock in exchange for InvestArk 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 both First United Common Stock and InvestArk common stock are
entitled to dissenter's 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 InvestArk 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."

<PAGE>   13
 
REGULATORY APPROVALS
 
     At this time, First United has received the approval of the Board of
Governors of the Federal Reserve to merge InvestArk into First United. First
United has also received the approval of the Arkansas Bank Commissioner to
consummate the Merger. See "The Merger -- Regulatory Approvals."
 
ACCOUNTING TREATMENT
 
     First United intends to treat the Merger as a pooling of interests for
accounting purposes. Consummation of the Merger is conditioned upon the receipt
of the opinion of Arthur Andersen & Co. that the Merger will qualify for the
pooling of interests accounting treatment. See "The Merger -- Accounting
Treatment."

(2)  The InvestArk pro forma equivalents represent the respective First
     United/InvestArk pro forma combined earnings, dividends and book value per
     common share multiplied by the applicable exchange ratio of 4.56 ($26.50
     First United stock value), 4.17 ($29.00 First United stock value) or 4.10
     ($29.50 First United stock value) shares of First United Common Stock for
     each share of InvestArk Common Stock so that the First United/InvestArk pro
     forma equivalent amounts are equated to the respective values for one share
     of InvestArk Common Stock. The exchange ratio is determined by dividing
     First United common stock to be received by the InvestArk stockholders by
     the 215,960 shares of InvestArk Common Stock currently outstanding.
 
SELECTED FINANCIAL DATA
 
     The table on the following page presents selected historical financial data
of First United and InvestArk 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 $175,000. The
First United historical data for each of the years in the five-year period ended
December 31, 1993 are based on the historical financial statements of First
United as audited by Arthur Andersen & Co., independent public accountants. The
InvestArk historical data for each of the years in the five-year period ended
December 31, 1993 are based on the historical financial statements of InvestArk
as audited by Martin and Company, independent auditors. 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 InvestArk give effect to the
exchange of each share of InvestArk common stock for 4.17 shares of First United
Common Stock.

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
     From time to time, the board of directors and management of InvestArk have
considered various strategies for InvestArk, including merging with a larger
company. Representatives of Stephens Inc. of Little Rock, Arkansas, InvestArk's
financial advisors, were authorized to solicit potential merger partners.
Stephens Inc. initially compiled a broad list of prospects who might have an
interest. This list was then narrowed to a list of potential merger partners,
including First United, based on an evaluation of compatibility with InvestArk's
business, ability to provide satisfactory terms, and business and financial
prospects. The board viewed each of these criteria as being important to the
maximization of the InvestArk stockholders' value and the long-term best
interest of stockholders. Of primary importance was the ability of the potential
merger partner to continue and increase the market value of the investment by
InvestArk stockholders through continued and enhanced business operations. The
board also considered whether a potential merger partner would be able to
provide InvestArk stockholders with readily marketable shares if a merger
transaction ensued and was effected through a tax-advantaged share exchange.
 
     Twelve companies from the list, including First United, were contacted on a
confidential basis concerning the possible merger. Eight of those companies were
sufficiently interested to sign confidentiality agreements and receive a package
of basic information about InvestArk. Although several parties indicated
additional general interest after reviewing the basic information, only First
United expressed a level of interest serious enough to merit further discussion.
After indicating specific interest and after the confidentiality agreement was
executed, First United was given the opportunity to examine the books and
records of InvestArk on a confidential basis. After First United completed its
review, the chairman of the board of InvestArk, with the assistance of
InvestArk's financial advisors, negotiated the specific financial terms of the
transaction with First United's Chief Financial Officer. These terms were placed
in a letter of intent which was executed on October 21, 1993. This letter of
intent provided the framework for the definitive, binding agreement between
InvestArk and First United. The definitive agreement was prepared and finalized
between October 21, 1993, and December 17, 1993. The definitive agreement was
formally presented to InvestArk's board for consideration on that date.
 
     In order to fully and finally evaluate the economic terms of the
transaction, the InvestArk board of directors, with the assistance of its
financial advisors, reviewed and evaluated the proposed transaction based on a
variety of criteria. The price was evaluated as a multiple of InvestArk's 1992
income, as a multiple of InvestArk's estimated 1993 net income, and as a
multiple of InvestArk's estimated September 30, 1993, book value. Assuming that
each First United share is valued in the range of $26.50 to $29.50, the First
United offer is equal to 11.70 times InvestArk's 1992 net income, and
approximately 1.5 times InvestArk's September 30, 1993 book value as estimated
at the time. These multiples were determined by the board of InvestArk to be
within the range of reasonableness when compared to other similar transactions.
 
     The proposed transaction was also evaluated in regard to the earnings
effect on First United and on the basis of the amount of dividends which, based
on past payment history, would result to InvestArk stockholders. These
comparisons also indicated that the proposed transaction would be beneficial.

     The InvestArk board, with the assistance of its financial advisors, also
compared the proposed transaction with other transactions which were apparently
similar. The table below is a summary of selected comparable merger transactions
that the board considered which reflects the names, dates, total value and
multiples of income and equity of the targets.

     The InvestArk board evaluated the price/earnings multiples of the stock of
selected publicly traded bank holding companies located in Arkansas, Missouri,
and Tennessee. This evaluation reflected that the trading range price of First
United shares was reasonable in comparison to the shares of other selected
publicly traded bank holding companies, and therefore the shares to be received
by InvestArk stockholders appeared to be reasonably valued by the market. The
board of InvestArk also reviewed a summary of selected comparable merger
transactions and determined that the total consideration was reasonable and
within the range of other similar transactions. The board of InvestArk also
reviewed the First United 1992 annual report on Form 10-K, as well as the Form
10-Q filed by First United for the period ended September 30, 1993. The board of
InvestArk, through its financial advisors, also requested certain additional
information regarding material litigation, environmental concerns and
nonperforming assets of First United. The historical and current market price
and trading trends for First United stock were also charted and reviewed. These
were viewed favorably by the board of InvestArk.
 
                                       15

     After all of these matters were reviewed and considered by the board, the
board determined that the First United offer was acceptable, and the Agreement
was approved on December 17, 1993, for presentation to the InvestArk
stockholders.
 
     For its role as financial advisor to InvestArk, Stephens Inc. is to receive
a cash payment of $100,000 from InvestArk, plus reimbursement for reasonable
expenses which are expected to be minimal. Payment is to be made at the closing
of the merger. Stephens Inc. is controlled by certain members of the families of
Wilton R. Stephens (deceased) and Jackson T. Stephens, who are also affiliates
of InvestArk. Various Stephens family members and trusts own in the aggregate
66.14% of the outstanding shares of InvestArk common stock and have entered into
an agreement with First United to vote such shares in favor of the Merger.
 
     Stephens Inc. has acted as a market maker for First United common stock,
which is traded on the National Association of Securities Dealers automated
quotation system national market system, for many years. However, Stephens Inc.
has temporarily suspended its role as a market maker in First United common
stock pending closing of the merger.
 
REASON FOR THE MERGER
 
     The acquisition of InvestArk will expand First United's current markets.
The banking subsidiaries of InvestArk are located in Melbourne, Arkansas and
Stuttgart, Arkansas. Currently, there are no banking offices in the First United
system located in Melbourne or Stuttgart. Thus, the acquisition of InvestArk
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 Melbourne and Stuttgart areas while increasing the earning power
of First United.
 
FAIRNESS OF THE TRANSACTION
 
     THE BOARD OF DIRECTORS OF FIRST UNITED AND INVESTARK BELIEVE THAT THE
PROPOSED ACQUISITION TERMS ARE FAIR TO THE STOCKHOLDERS OF BOTH FIRST UNITED AND
INVESTARK AND RECOMMEND A VOTE IN FAVOR OF THE ADOPTION OF THE AGREEMENT.
 
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.
 
     Under the terms of the Agreement, InvestArk will be merged with and into
First United in exchange for the issuance by the Company of a maximum of 985,849
newly issued shares of First United Common Stock to the holders of the common
stock of InvestArk.
 
     The Agreement provides that the stockholders of InvestArk will receive
total consideration of $26,125,000 consisting of fully paid and nonassessable
shares of Common Stock, $1.00 par value of First United, if the average price of
First United Common Stock is between $26.50 and $29.50. If the average price is
in this range the number of shares of First United common stock to be exchanged
for all of the issued and outstanding shares of InvestArk Common Stock will be
determined by dividing $26,125,000 by the average price 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.
Notwithstanding the foregoing, the number of shares of First United Common Stock
to be exchanged shall not be less than 885,593 and shall not be greater than
985,849 which equate to an average price of First United Common Stock of $29.50
and $26.50, respectively.
 
     If the average price of First United common stock is less than $26.50, the
amount of shares issued shall equal the ceiling of 985,849 shares. Also, if the
average price of First United common stock is more than
 
                                       16
<PAGE>   21
 
$29.50, the amount of shares issued shall equal the floor of 885,593 shares. The
total consideration exchanged will vary from $26,125,000 if the average price is
either higher than $29.50 or lower than $26.50. For example, if the average
price is $35.00, the InvestArk stockholders shall receive 885,593 shares of
First United common stock, each share having a value of $35.00 representing
total consideration of $30,995,755. If the average price is $22.00, the
InvestArk stockholders shall receive 985,849 shares of First United common
stock, each share having a value of $22.00 representing total consideration of
$21,688,678. See "The Merger -- Exchange Ratio for the Merger".
 
     Fractional shares of First United Common Stock shall not be issued and any
InvestArk stockholder entitled to receive a fractional share shall receive a
cash payment equal to the value of the fractional share based on the average
price of First United Common Stock.
 
     The Agreement can be terminated by InvestArk if the First United Common
Stock average price is less than $22.00 and the scheduled closing date is more
than 120 days after the date of the Agreement. First United may terminate the
Agreement if the First United Common Stock average price is $35.00 or more and
the scheduled closing date is more than 120 days after the date of the
Agreement. However, First United may not terminate the Agreement based upon the
aforementioned ground if: (i) First United has agreed or announced its intention
to be acquired by a third party or merge into a third party that is the
surviving corporation, or (ii) First United has received an unsolicited offer of
proposal to engage in such a transaction. In addition, either party may
terminate the Agreement, if the Merger is not closed on or before May 31, 1994
provided that the failure to close is not caused by a breach of the Agreement by
the party seeking to terminate it.
 
     First United and InvestArk have agreed, for the period prior to the
consummation of the merger, to operate their respective businesses only in the
usual, regular and ordinary course. In addition, First United and InvestArk will
use reasonable efforts to maintain and keep their respective 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. First United and InvestArk have further agreed that,
prior to consummation of the Merger, they 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 InvestArk to obtain any necessary approvals, adversely
affect the ability of First United or InvestArk to perform their covenants and
agreements under the Agreement, or result in any of the conditions to the Merger
not being satisfied. InvestArk 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 InvestArk
stockholders by two-thirds of all outstanding shares; (b) approval by First
United stockholders by two-thirds of all outstanding shares; (c) approval by the
appropriate bank regulatory authorities; (d) receipt by the Company of an
opinion from Arthur Andersen & Co. 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 benefited 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 ("Board") for First United to
acquire InvestArk. 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 Bank Department ("Department")
for approval of the Merger. The application made to the Board was approved on
March 15, 1994. The application made to the department was approved on February
24, 1994.
 
ANTITRUST MATTERS
 
     The Department of Justice has thirty (30) calendar days after approval by
the Board in which to challenge the proposed Merger on anti-trust
considerations. The approval letter from the Board provided that the Merger may
not be consummated until thirty (30) calendar days after the effective date of
such letter. The thirty calendar days has expired from the effective date of the
Board's approval. The letter also provided that the transaction must be
consummated no later than three (3) months from that effective date unless the
period is extended for good cause by the Board upon request by First United.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     General. For federal income tax purposes the law provides that participants
(a "Party" or "Parties") in a transaction, including the transaction
contemplated by the Merger, which meets certain specific statutory and case law
requirements (a "reorganization") are entitled to special tax treatment which
effectively defers the instance of taxation on any gain inherent in a
reorganization. This result is achieved by treating the Parties as if they had
continued substantially unaffected by the reorganization. Under Section 361, no
gain or loss is recognized by a Party as a result of a reorganization (Section
references under this caption are to the Internal Revenue Code of 1986, as
amended (the "Code"). Section 362(b) provides that the tax basis of property
received by a Party in a reorganization is the same as it would be in the hands
of the transferor, increased by any gain recognized by the transferor on such
transfer. The tax basis of the underlying assets of the Parties is not changed.
 
     For the stockholders of corporations which are Parties to a reorganization,
Section 354 provides that no gain or loss shall be recognized to such
stockholders on the exchange of their stock of one Party for the stock of
another Party. Section 358 provides that the basis of the stock received by such
a stockholder shall be the same as the basis of the stock surrendered in the
exchange. Under Section 1223, the holding period of the stock received by a
stockholder of one of the Parties will include the period for which the stock
exchanged by such stockholder was held.
 
     As a result of case law interpreting the special tax treatment available
for reorganizations, there is also (i) a continuity-of-interest concept which
requires that, in the aggregate, stockholders of each of the corporate parties
to a reorganization maintain a minimum level of equity ownership in the
surviving corporate party, (ii) a continuity of business enterprise requirement;
and (iii) a valid business purpose requirement.
 
     Tax Consequences. It is expected that at or prior to the closing date of
the Merger, InvestArk will receive closing tax opinion of tax counsel to
InvestArk that for federal income tax purposes, under current law, assuming that
the Merger and related transactions will take place as described in the Merger
Agreement and that the case law requirements described above, relating to
continuity of stockholder interest, continuity of business enterprise and valid
business purpose, are satisfied, the Merger will constitute a reorganization
within the meaning of Section 368(a)(1)(A) of the Code, and First United and
InvestArk each will be a Party to the reorganization within the meaning of
Section 368(b) of the Code.
 
     If the Merger constitutes such a reorganization, the following will be all
of the material federal income tax consequences of the Merger to InvestArk and
its stockholders in the opinion of Shults, Ray & Kurrus: (i) no gain or loss
will be recognized by the InvestArk stockholders upon the receipt of First
United Common Stock in exchange for InvestArk common stock in connection with
the Merger; (ii) the tax basis of the First
 
                                       18
<PAGE>   23
 
United Common Stock to be received by the InvestArk stockholders in connection
with the Merger will be the same as the basis in the InvestArk Common Stock
surrendered in exchange therefor; (iii) the holding period of the First United
Common Stock to be received by the InvestArk stockholders in connection with the
Merger will include the holding period of the InvestArk common stock surrendered
in exchange therefor, provided that InvestArk common stock is held as a capital
asset at the effective time of the Merger; and (iv) the payment of cash to
stockholders of InvestArk in lieu of the issuing fractional shares of First
United Common Stock will be treated as if the fractional shares were distributed
as part of the exchange and then redeemed by First United for cash and the
payments received will be treated as distributions in redemption of the
fractional shares, subject to the provisions of Section 302 of the Code.
 
     Cash Received by Holders of InvestArk or First United Common Stock Who
Dissent. A stockholder of InvestArk or First United who perfects his dissenter's
rights under the laws of Arkansas and who receives payment of the fair value of
his shares of InvestArk common stock will be treated as having received such
payment in redemption of such stock. Such redemption will be subject to the
conditions and limitations of Section 302 of the Code, including the attribution
rules of Section 318. In general, if the dissenting shares of common stock are
held by the holder as a capital asset at the effective time of the Merger, such
holder will recognize capital gain or loss measured by the difference between
the amount of cash received by such holder and the basis for such shares. Each
holder of common stock who contemplates exercising his dissenter's rights should
consult his own tax adviser as to the possibility that any payment to him will
be treated as dividend income.
 
     THE DISCUSSION SET FORTH ABOVE DOES NOT ADDRESS THE STATE, LOCAL OR FOREIGN
TAX ASPECTS OF THE MERGER. THE DISCUSSION IS BASED ON CURRENTLY EXISTING
PROVISIONS OF THE CODE, EXISTING AND PROPOSED TREASURY REGULATIONS THEREUNDER
AND CURRENT ADMINISTRATIVE RULINGS AND COURT DECISIONS. ALL OF THE FOREGOING ARE
SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING VALIDITY OF
THIS DISCUSSION. EACH INVESTARK AND FIRST UNITED STOCKHOLDER SHOULD CONSULT HIS
OR HER OWN TAX ADVISOR WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE
MERGER TO HIM OR HER, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND
FOREIGN TAX LAWS.
 
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
consolidated financial statements to include the assets, liabilities,
stockholders' equity and results of operations of InvestArk 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 INVESTARK 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 INVESTARK, 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 InvestArk 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 InvestArk 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
 
                                       19
<PAGE>   24
 
with Section 4-26-1007 and is qualified by reference to those statutory sections
which are attached, hereto by Annex.
 
     A holder of InvestArk 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 InvestArk
Bankshares, Inc., 412 South Main Street, Stuttgart, Arkansas 72021, Attention:
Harry C. Erwin, Chief Executive Officer. 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 INVESTARK 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 INVESTARK 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 by Annex.
 
     A holder of either InvestArk or 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.
 
                                       20
<PAGE>   25
 
     Any written notice of objection to the Agreement pursuant to clause (a) of
the immediately preceding paragraph should be mailed or delivered to InvestArk
Bankshares, Inc., 412 South Main Street, Stuttgart, Arkansas 72021, Attention:
Mr. Harry C. Erwin, Chief Executive Officer (if you are a stockholder of First
United, to First United Bancshares, Inc., Main and Washington Streets, El
Dorado, Arkansas 71730, Attention: John E. Burns, Vice President and Chief
Financial Officer). Because the written objection must be delivered prior to or
at the stockholder vote 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 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 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 within
not fewer than thirty (30) nor more than sixty (60) days 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 stockholders 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
 
     If the average sales price is between $26.50 and $29.50 the number of
shares of First United Common Stock to be issued pursuant to the Merger is
calculated by dividing $26,125,000 by the average sales price of First United
Common Stock for all trades occurring during the period of ten (10) days on
which one or more trades actually takes place and which ends immediately prior
to the second trading day preceding the closing date. If the average sales price
is less than $26.50 the total number of shares exchanged will be the ceiling of
985,849. If the average sales price is more than $29.50 the total number of
shares exchanged will be the floor of 885,593. The exchange ratio for the Merger
is calculated by taking the number of shares of First United Common Stock to be
issued and dividing this number by the total number of issued and outstanding
shares of InvestArk common stock, which is 215,960. The following table
illustrates a range of average sales prices for First United Common Stock and
based upon these average sales prices, calculates the number of shares of First
United Common Stock to be issued and the resulting exchange ratio. Furthermore,
the table illustrates the total consideration to be exchanged which shall vary
depending upon the average sales price of First United Common Stock. This table
is for illustration purposes only and should not be relied upon as the actual

NOTES TO PRO FORMA COMBINING FINANCIAL STATEMENTS
 
     (1) The adjustments to the Pro Forma Combining Financial Statements do not
         include direct expenses related to the Merger, which will be recorded
         at the time of the Merger. The pro forma data are not necessarily
         indicative of the operating results or financial position that would
         have occurred had the Merger been consummated at the dates indicated,
         nor necessarily indicative of future operating results of financial
         position.
        
     (2) These adjustments reflect the issuance of approximately 900,862 shares
         of First United Common Stock in exchange for all InvestArk common
         stock and the retirement of InvestArk common stock held in treasury.
         The actual number of shares of First United Common Stock to be issued
         pursuant to the Merger will fluctuate based upon the average price of
         First United Common Stock assumed to be at 29.00 for these Pro Forma
         Combining Financial Statements.
        
     (3) Pro forma per share data are based on the number of shares of First
         United Common Stock that would have been outstanding had the Merger
         occurred at the beginning of the earliest period presented. The
         following table illustrates pro forma earnings per share based upon
         the allowable minimum and maximum average price of First United Common
         Stock of $26.50 and $29.50, respectively, pursuant to the Agreement.

             ELECTION BY INVESTARK STOCKHOLDERS UNDER THE 1987 ACT
 
ELECTION INCIDENTAL TO THE MERGER
 
     THE ELECTION BY THE STOCKHOLDERS OF INVESTARK 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
 
     InvestArk 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
stockholders of First United elected to be governed by the 1987 Act by amending
its Articles of Incorporation.
 
     The 1965 Act and 1987 Act have statutory merger procedures that must be
complied with in order to legally consummate a merger. Although both acts
contain similar provisions, it is advisable for InvestArk 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 InvestArk
common stock will authorize InvestArk 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 InvestArk
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,
 
                                       27
<PAGE>   32
 
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
that 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.
 
     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 in
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
 
                                       28
<PAGE>   33
 
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.
 
     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 extend 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 having assets of $286 million, deposits of $244
million, and stockholders' equity of $31 million, as of September 30, 1993.
Between 1981 and 1988, First United acquired three other banks in different
cities within Arkansas. The banks acquired were the First National Bank of
Magnolia, Magnolia, Arkansas, having assets of $201 million, deposits of $176
million, and stockholders' equity of $21 million, as of September 30, 1993;
Merchants and Planters Bank, N.A. of Camden, Camden, Arkansas, having assets of
$90 million, deposits of $81 million, and stockholders' equity of $9 million as
of September 30, 1993; and City National Bank of Fort Smith, Fort Smith,
Arkansas, having assets of $310 million deposits of $271 million and
stockholders' equity of $27 million as of September 30, 1993. Each of the banks
are wholly-owned by First United, and, furthermore, are banks organized under
the laws of the United States and are regulated by the Office of the Comptroller
of the Currency.
 
     On November 30, 1993 First United acquired Commerce Financial Corporation
which wholly-owned Commercial Bank at Alma, Alma, Arkansas. Commerce Financial
Corporation was merged into First United which succeeded to the ownership of
Commercial Bank at Alma which had assets of $45 million, deposits of $40
million, and stockholders' equity of $5.5 million as of the date of closing.
Commercial Bank at Alma is a state-chartered institution and is regulated under
the supervision of the Arkansas Bank Department.
 
     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.
 
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 application 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
 
                                       30
<PAGE>   35
 
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 also 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 penalties ranging from $5,000 per day to $l,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-based capital
standards through the end of 1992, at which time the standards became fully
effective. The Company's year end 1993 Tier 1 ratio of 18.83% and Total capital
ratio of 19.53% exceeds the current minimum regulatory requirements of 4.00% and
8.00% respectively.
 
     The table below illustrates all of the capital requirements applicable to
First United and its subsidiaries.

                           INVESTARK BANKSHARES, INC.
DESCRIPTION OF BUSINESS
 
     InvestArk is a multi-bank holding company which owns 99.7% and 100% of the
common stock of The Bank of North Arkansas, Melbourne, Arkansas ("North
Arkansas") and First Stuttgart Bank and Trust Company, Stuttgart, Arkansas,
("First Bank") respectively. InvestArk may engage, directly or through
subsidiaries, in those activities closely related to banking which are
specifically permitted under the Bank Holding Company Act of 1956, as amended.
 
     InvestArk was organized as an Arkansas bank holding company on July 20,
1984. The sole asset of InvestArk is the stock it holds in its two bank
subsidiaries. The subsidiaries grant commercial, installment and real estate
loans to customers principally in Arkansas County and Izard County, Arkansas. As
of September 30, 1993, these subsidiaries had a total of $83,133,078 of loans
outstanding and a loan loss reserve of $896,091. InvestArk adjusted its
allowance for possible loan losses and reserve against other real estate owned
to add $690,000 in the fourth quarter of 1993. This amount resulted in a
reduction of the same amount in InvestArk's capital account. However, this
reduction in capital was substantially recouped by InvestArk's retention of
fourth quarter earnings. For a more complete discussion regarding the
aforementioned mentioned adjustment, see "InvestArk Bankshares,
Inc. -- Management Discussion and Analysis".
 
MANAGEMENT'S DISCUSSION AND ANALYSIS
 
     The following discussion and analysis highlights the significant factors
affecting InvestArk's consolidated financial statements. For a more complete
understanding of the following discussion, reference should be made to
InvestArk's consolidated financial statements and related notes thereto
presented elsewhere in this Proxy Statement.
 
                             BALANCE SHEET ANALYSIS
 
     Financial Condition. At December 31, 1993 total assets were $184,904,000
reflecting a modest decrease over the December 31, 1992 level of $190,940,000.
InvestArk 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.
 
     InvestArk's loan portfolio represents the largest component of the earning
asset base and has the largest impact upon income from earning assets. However,
the loan portfolio continues to experience modest declines as a result of
weakened loan demand. Inherent in InvestArk's loan portfolio is credit risk.
InvestArk maintains an allowance against which loan losses are charged.
Management evaluates the allowance adequacy quarterly. Management's methodology
to determine the adequacy of the allowance considers specific credit reviews,
past loan loss experience, current economic conditions and trends and the volume
and composition of the loan portfolio. See tables 5 through 9 and "Earnings
Analysis -- Provision for Possible Loan Losses" for additional information.
 
     Investment securities continues to grow. At December 31, 1993, investment
securities had a balance of $87,864,000 as compared to December 31, 1992 level
of $82,462,000. The increase from 1992 to 1993 primarily reflects a shift out of
cash and due from bank accounts to investment securities in an effort to
maximize earning asset levels. See tables 3 and 4.
 
                                       33
<PAGE>   38
 
     As the primary source to fund earning assets, deposits have decreased to a
level of $163,300,000 at December 31, 1993 as compared to December 31, 1992
level of $170,102,000. Time deposits decreased by $8,110,000 or 10% for the year
ended December 31, 1993 due to declining interest rates and the resulting shift
from interest bearing deposits due to depositors shortening their time horizons.
See table 10 for further analysis of time deposits in excess of $100,000.
 
     Liquidity and Interest Rate Sensitivity Management. Liquidity is the
ability of the bank to fund the needs of its borrowers, depositors and
creditors. Based on maturity structure and anticipated loan and deposit funding
requirements, InvestArk anticipates that its liquidity requirements will be met
in the foreseeable future. InvestArk's management is of the opinion that
traditional sources of maturing loans and investment securities, federal funds
and the base of core deposits will be adequate to provide liquidity needs. See
tables 4, 6 and 10 for additional information on certain investment, loan and
time deposit maturities.
 
     The matching of assets and liabilities may be analyzed by examining the
extent to which such assets and liabilities are "interest rate sensitive" and by
monitoring an institution's interest rate sensitivity "gap." An asset or
liability is said to be interest rate sensitive within a specific time period if
it will mature or reprice within that time period. The interest rate sensitivity
gap is defined as the difference between the amount of interest-earning assets
expected to mature or reprice within a specific time period and the amount of
interest-bearing liabilities expected to mature or reprice within that time
period. A gap is considered positive when the amount of interest rate sensitive
assets maturing within a specific time frame exceeds the amount of interest rate
sensitive liabilities maturing within that same time frame. During a period of
falling interest rates, a positive gap tends to result in a decrease in net
interest income. Whereas in a rising interest rate environment, an institution
with a positive gap could experience the opposite results. The table below
represents InvestArk's gap position as of December 31, 1993 (in thousands):

</TABLE>
 
     At December 31, 1993, InvestArk's interest-bearing assets maturing or
repricing within one year exceeded the interest-bearing liabilities maturing or
repricing within the same time period. Based upon its evaluation of the interest
rate market, management feels InvestArk's gap position is in compliance with its
asset/liability management policies.
 
     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 December 31, 1993, InvestArk's Tier 1 capital and total capital as a
percentage of total risk-adjusted assets were each 13.5% which exceeded the
required minimum levels. The required minimum levels for Tier 1 capital and
total capital are 4.0% and 8.0%, respectively.
 
                               EARNINGS ANALYSIS
 
     For the years ended December 31, 1993, 1992, and 1991, net income was
approximately $1,278,000, $2,233,000, and $907,000, respectively. For the years
ended December 31, 1993, 1992 and 1991, the return on average assets was 0.7%,
1.3%, and 0.5%, respectively, while the return on average equity was 7.6%,
14.3%, and 6.3%, respectively.
 
     The primary components of total income and expense which affect net income
are net interest income, provision for possible loan losses, non-interest
income, non-interest expense and the provision for income taxes. Significant
factors affecting these categories are presented below.
 
                                       34
<PAGE>   39
 
     Net Interest Income. For the years ended December 31, 1993, 1992, and 1991,
net interest income was $7,510,000, $7,819,000 and $6,777,000, respectively. The
decrease in 1993 over 1992 levels results from levels of yields on investment
securities and yields decreasing relatively more as compared to rate decreases
on interest-bearing deposits. These increases in 1992 over 1991 levels result
from increases in earnings assets and a decrease in interest expense which was
the result of falling interest rates. See Tables 1 and 2.
 
     Provision for Possible Loan Losses. For the year ended December 31, 1993,
InvestArk made additions to its allowance for possible loan losses of
approximately $600,000 compared to $64,000 in 1992 and $1,463,000 in 1991.
Almost 60% or $311,000 of the increase in 1993 as compared to 1992 levels
results primarily from concern with respect to decrease in agricultural yields
in the fall of 1993. The drop in yields was attributable to extremely dry
weather conditions throughout the crop cycle which conditions were only
partially offset by improved commodity prices. Based on such data, management
determined that a reserve of approximately 1.25% was necessary for its
agribusiness-related loans. As discussed in Note 3 to the consolidated financial
statements the markets in which InvestArk operates are dependent upon the
agribusiness economic sector. Additionally, the credit worthiness of a large
loan was downgraded and a portion specifically reserved which accounted for 15%
of the increase in the provision during 1993. As a result of the plant
modernization measures undertaken by this borrower in 1993, cash flows from
operations were diverted from the scheduled debt repayments to capital
expenditures. Pending resumption of principal and interest payments, the loan
was placed on nonaccrual and specifically reserved based on underlying
collateral values.
 
     Net charge-offs on loans were $179,000 in 1993, $175,000 in 1992 and
$929,000 in 1991, respectively. The allowance for loans and lease losses were
$1,494,000 or 1.8% of loans at December 31, 1993, compared to $1,073,000 or 1.2%
at December 31, 1992.
 
     Non-Interest Income. Total non-interest income for the year ended December
31, 1993 was $1,509,000 as compared to $1,504,000 for 1992 and $1,615,000 in
1991. The large increase in 1992 over 1991 was primarily in the category of
other operating income. Other operating income increased primarily because of
lease rental income derived from leveraged lease transactions entered into
during 1991. Management believes the level of non-interest income prior to 1992
is more representative of the levels to be expected in the future as the
leverage leases terminate in April 1994.
 
     Non-Interest Expense. Total non-interest expense for the year ended
December 31, 1993 was $6,988,000 as compared to $6,517,000 for 1992 and
$5,890,000 in 1991. The increase for 1993 is primarily in the category of
employee benefits. The increase for 1992 is primarily in the category of other
expense. Other expense increased primarily because of increased annual FDIC
insurance assessments, legal fees and costs attributable to the foreclosure and
subsequent writedowns of other real estate.
 
     Provision for Income Taxes. Income tax expense for the years ended December
31, 1993, 1992 and 1991 was $148,000, $501,000, and $128,000, respectively.
Effective tax rates were 10%, 18%, and 12% for 1993, 1992, 1991, respectively.
Note 7 to the consolidated financial statements provides further details of the
applicable income tax expense.
 
                               REGULATORY ISSUES
 
     Pursuant to the Interest Rate Control Amendment to the Constitution of the
State of Arkansas, "consumer loans and credit sales" have a maximum limitation
of 17% per annum and all "general loans" have a maximum limitation of 5% over
the Federal Reserve Discount Rate in effect at the time the loans are made. The
Arkansas Supreme Court has determined that "consumer loans and credit sales" are
"general loans" and are subject to the limitation of 5% over the Federal Reserve
Discount Rate as well as a maximum limitation of 17% per annum. As a general
rule, InvestArk is required to comply with the Arkansas usury laws on loans made
within the State of Arkansas.

<PAGE>   40
 
                              ACCOUNTING STANDARDS
 
     During 1993 the Financial Accounting Standards Board (FASB) issued SFAS No.
114 (Accounting by Creditors for Impairment of a Loan) which becomes effective
beginning in 1995. This statement defines the measurement requirements for loans
that are impaired or deemed to be troubled debt restructurings. Management has
not determined the effect that this statement will have upon adoption.
 
     Also during 1993 the FASB issued SFAS No. 115 "Accounting for Certain
Investments in Debt and Equity Securities," which InvestArk will adopt on
January 1, 1994. This statement addresses the accounting and reporting for
investments in debt and certain equity securities. Debt securities not
classified as trading account securities or investment securities expected to be
held to maturity and all equity securities will be classified as
available-for-sale securities and reported at fair value, with net unrealized
gains and losses reported, net of tax, as a separate component of stockholders'
equity. InvestArk believes the impact of adopting this statement will not be
material to its financial position or results of operations as it expects to
hold its investment securities to maturity.

     The change in interest due to both volume and yield/rate has been allocated
to change due to volume and change due to yield/rate in proportion to the
absolute value of the change of each. Tax exempt income has been adjusted to a
tax equivalent basis using a tax rate of 34% for the years 1993, 1992 and 1991.
The balances of non-accrual loans and related income recognized have been
included for purposes of these computations.

     Included in the above maturity schedule are mortgage related securities
totaling $10,075,000 which have contractual maturities as follows: Within One
Year -- $3,369,000; After One But Within Five Years -- $2,863,000; After Five
But Within Ten Years -- $1,772,000; After Ten Years -- $2,071,000. Due to the
nature of mortgage related securities, the actual maturities of these
investments can be substantially shorter than their contractual maturity.
Management believes the actual weighted average maturity of the entire mortgage
related portfolio to be approximately 7.35 years.
 
     At December 31, 1993 there were no securities in the portfolio of any one
issuer with a carrying value exceeding ten percent of total stockholders'
equity.

     If interest on non-accrual loans had been accrued, such income would have
approximated $39,000 in 1993. The interest which was included in earnings for
1993 for non-accrual loans is immaterial.
 
     At December 31, 1993, InvestArk had no loan concentrations greater than ten
percent of total loans except as shown in Table 5.
 
     InvestArk 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, 1993, InvestArk has no loans about which Management has serious
doubts as to their collectibility other than those disclosed above.

     During 1993, the Board of Directors of InvestArk held 16 meetings and all
the incumbent directors then in office were in attendance at more than
seventy-five percent of the meetings. The Board of Directors does not have a
nominating, compensation or audit committee.
 
TRANSACTIONS WITH MANAGEMENT
 
     Directors and executive officers of InvestArk and its subsidiaries, their
associates and members of their immediate families were customers of and had
transactions including loans and commitments to lend with subsidiaries of
InvestArk in the ordinary course of business during 1993. All such loans and
commitments were made by the 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 December 31, 1993, the aggregate of these related party loans was
approximately $2,212,000 or approximately 2.6% of total loans outstanding of the
subsidiaries and 2.0% of pro forma combined capital accounts.
 
PRINCIPAL STOCKHOLDERS OF INVESTARK
 
     The following table sets forth, as of December 31, 1993, the only persons

FEDERAL RESERVE BOARD INVESTIGATIONS
 
     On March 4, 1993, the Board of Governors of the Federal Reserve System (the
"Board") ordered its staff to commence a formal investigation to review the
ownership and control of Worthen Banking Corporation of Little Rock, Arkansas
("Worthen") for compliance with the control provisions of the Bank Holding
Company Act and the Change in Bank Control Act. This investigation appears to be
focused primarily on whether members of the families of Jackson T. Stephens and
Wilton R. Stephens (deceased) and affiliated entities (collectively, the
Stephens Family), who currently own 26% of Worthen's outstanding common stock,
have exerted control over Worthen in violation of the above-referenced statutes.
First United has been advised by the Stephens Family that the investigation is
continuing, but the Board has not announced any finding or determination that
any violation of law has or has not occurred. The events and transactions which
are the subject of the Worthen investigation do not in any way relate to or
involve InvestArk or First United.
 
     In addition, in February 1993, InvestArk management was advised by the
Federal Reserve Bank of St. Louis (the "St. Louis FED") that the agency had
initiated a review of certain transactions between InvestArk's bank subsidiaries
and Stephens Inc., a registered broker-dealer owned by the Stephens Family.
These transactions involved the purchase and sale of municipal and other
securities; and the purpose of the review, which is still ongoing, is to
determine whether the transactions violated the prohibitions of Sections 23A and
23B of the Federal Reserve Act. Section 23A places several restrictions on what
it refers to as "covered transactions" between a bank and its affiliates. Except
as exempted by the Federal Reserve Board, covered transactions include bank
loans or extensions of credit to an affiliate, purchases of securities issued by
an affiliate, purchases of assets from an affiliate, the bank's acceptance of
securities issued by an affiliate as collateral for a loan or extension of
credit, and the bank's issuance of a guaranty, acceptance, or letter of credit
on behalf of an affiliate. Covered transactions are subject to two general
limitations. First, with respect to quantitative restrictions, covered
transactions between a bank (including its subsidiaries) and an affiliate are
limited to 10% of the bank's capital and surplus. Aggregate covered transactions
between a bank (including its subsidiaries) and all affiliates are limited to
20% of the bank's capital and surplus. Secondly, any covered transaction between
a bank and an affiliate must be on terms and conditions that are consistent with
safe and sound banking practices. Certain covered transactions are subject to
collateral requirements. The amount of collateral required depends on the type
of collateral used, as set forth in the statute. Depending upon the type of
collateral used the market value of such collateral must equal between 100% of
the covered transaction and 130% of the covered transaction. Section 23A also
contains an absolute prohibition on the bank's (or bank subsidiaries) purchase
of low-quality assets from an affiliate. Section 23B generally requires that a
bank and its subsidiaries engage in transactions with affiliates only on terms
and under circumstances, including credit standards, that are substantially the
same, or at least as favorable to the bank or its subsidiary, as those
prevailing at the time for comparable transactions with or involving
non-affiliated companies. Alternatively, in the absence of comparable
transactions, any such transactions must be on terms and under circumstances,
including credit standards, that in good faith would be offered to or applied to
non-affiliated companies.
 
     The St. Louis FED has not announced any results of its review. However,
First United's obligation to consummate the Merger is conditioned upon the St.
Louis FED not having notified either of the parties of actual or proposed
regulatory action with respect to the investigation that could reasonably be
expected to have an adverse effect on First United, InvestArk or InvestArk's
bank subsidiaries. InvestArk management has reviewed the transactions under
review by the St. Louis FED and determined that InvestArk's bank subsidiaries
have benefitted from significant appreciation of the securities purchased taken
as a whole. In order to assure compliance with Section 23A and 23B of the
Federal Reserve Act, InvestArk and its subsidiary banks underwent a two step
process (1) an internal review was conducted to identify all "covered"
transactions with Stephens Inc., if any, and (2) new policies and procedures
were established and reviewed by the St. Louis FED, to ensure compliance with
the Section 23A and 23B of the Federal Reserve Act with respect to any future
affiliate transactions. InvestArk management has no reason to believe that the
St. Louis FED will take any action with respect to the transactions under review
which would have a material adverse effect on First United, InvestArk or
InvestArk's bank subsidiaries.

RESULTING OWNERSHIP IN FIRST UNITED
 
     The W. R. Stephens Trust beneficially owns 207,884 shares of First United
Common Stock which equals 4.86% of the issued and outstanding shares of First
United. The W.R. Stephens Jr. Trust beneficially owns 2,100 shares of First
United Common Stock which equals .04% of the issued and outstanding shares of
First United. The additional shares of First United Common Stock to be received
by these and other Stephens Family members in the Merger will increase the total
number of shares beneficially owned by the Stephens Family to a maximum of
862,140, or 16.40% of the outstanding shares of First United Common Stock.
Accordingly, the Stephens Family would be required to file a Notice of Change in
Bank Control and receive approval of the Board in order to own and vote these
shares directly. Because of the existence of the Worthen investigation, and in
lieu of making such a filing at this time, the Stephens family has agreed to
place all of the shares of First United Common Stock its members and affiliates
will receive in the Merger in trust with an independent trustee. The
beneficiaries of the Stephens Trust and the number of shares deposited therein
by each of them are set forth in the following table. The agreement governing
the Stephens Trust provides that the Trustee shall have sole authority to vote
the shares deposited by the beneficiaries, and shall vote them in proportion to
the percentage of shares of First United Common Stock voted for or against any
proposal brought before the stockholders of First United. However, any
abstention of First United Common Stock will not be counted in computing the
above described percentage. (The 209,984 shares of Common Stock of First United
beneficially owned by the W.R. Stephens Trust and the W.R. Stephens Jr. Trust
will continue to be owned and voted directly by their respective trustees). The
beneficiaries of the Stephens Trust will retain dispositive power over the
shares of First United Common stock deposited therein; provided that they have
agreed not to sell 5% or more of the outstanding shares of First United Common
Stock to a purchaser or group of purchasers without the prior written approval
of the Board unless the sale is transacted in connection with an acquisition of
First United approved by its Board of Directors. The Stephens Trust will
terminate when, and if, the Stephens Family ceases to own 10% or more of the
shares of First United's outstanding Common Stock or the Board grants the
Stephens Family permission to own and vote the shares held therein directly.
Based upon the maximum of 985,849 shares to be issued to the stockholders of
InvestArk, the Stephens Trust will own of record 12.41% of the outstanding
shares of First United Common Stock as reflected by the table below.

REGISTRATION RIGHTS
 
     Pursuant to the Shareholders Agreement dated December 17, 1993 by and
between W. R. Stephens, The W. R. Stephens, Jr. Trust, The W. R. Stephens Trust,
Jackson T. Stephens, Warren A. Stephens and The Elizabeth Ann Stephens Trust
(the "Shareholders") and First United, the Shareholders, on or after the
effective date of the Merger, shall have three different types of registration
rights.
 
     Demand Rights on Form Other Than S-3. The Shareholders have the right to
make two requests of First United to register under the Securities Act, in each
case, at least Five Million ($5,000,000) in market value of First United Common
Stock beneficially owned by the Shareholders. First United has agreed to use its
best reasonable efforts to register the shares as soon as practicable if a
request is made. However, First United will be entitled to postpone for a
reasonable period of time the registering of the Common Stock, if, in good
faith, the board of directors of First United determines it is advisable because
registering the Common Stock at such time would be materially detrimental to
First United. If the filing is delayed by 90 days First United shall obtain the
written opinion of a nationally recognized banking firm supporting the
determination to postpone the filing. If the Shareholders exercise their right
of demand, they shall pay all out-of-pocket expenses incurred in connection with
the registration of the securities, except for registration on Form S-3 as
discussed below.
 
     Demand Rights on Form S-3. If a demand for registration is made in
accordance with the immediately preceding paragraph and such registration is
filed on Form S-3, the Shareholders shall pay all underwriting discounts and
commissions applicable to the First United Common Stock held by said
Shareholders, the fees and disbursements of their own counsel and accountants
and all other expenses associated with the offering of the Shareholder's stock.
If First United chooses to issue additional shares of common stock concurrently
with the registration of Shareholder's stock, it shall pay all underwriting
discounts and commissions applicable to the additional stock, the fees and
disbursements of its own counsel and accountants and its pro rata share of all
other expenses of the offering.
 
     Piggy-Back Rights. If at any time First United proposes to register any of
its securities under the Securities Act of 1933, other than securities to be
issued pursuant to a stock option or other employee benefit plan, First United
has agreed to give written notice to the Shareholders of such a registration.
If, within five days after receipt of such notice, the Shareholders submit a
written request to First United, First United shall include the First United
Common Stock held by the Shareholders and specified in the Shareholder's request
in such a registration. Notwithstanding the foregoing, if the offering of the
Shareholder's securities is to be made by or through underwriters, First United
shall not be required to include the shares of First United Common Stock of the
Shareholders if the managing or co-managing underwriters reasonably believe in
good faith that such inclusion would materially and adversely affect such
offering. Under the right of "piggy-back" registration, First United shall pay
all expenses incurred in connection with registration of the securities.

state banks, savings and loan associations, securities dealers, mortgage

COMPARISON OF RIGHTS OF HOLDERS OF INVESTARK COMMON STOCK AND FIRST UNITED
COMMON STOCK
 
     InvestArk 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. Holders of
InvestArk 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 InvestArk, and
the rights of security holders of First United, see "Election by InvestArk
Stockholders under the 1987 Act -- Result of Election".
 
     The holders of InvestArk common stock and First United Common Stock are
both entitled to cumulative voting for directors. Pursuant to First United's
By-Laws, the number of directors of the corporation may not be less than three
nor more than twenty-five. The InvestArk By-Laws require that the number of
directors may not be less than three nor more than ten. Furthermore, holders of
InvestArk common stock and First United common stock do not have preemptive
rights with respect to issuance of additional securities.
 
     Both InvestArk 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 liabilities
incurred by them in their conduct and good faith 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 InvestArk Articles of Incorporation do not
contain a like provision. However, under the 1965 Act, InvestArk must have a
two-thirds ( 2/3) majority vote of all votes entitled to be cast to adopt a
merger.

                          INDEPENDENT AUDITOR'S REPORT
 
The Board of Directors
Investark Bankshares, Inc.
Stuttgart, Arkansas
 
     We have audited the consolidated balance sheets of Investark Bankshares,
Inc. and subsidiaries at December 31, 1993 and 1992, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the years in the three year period ended December 31, 1993. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Investark
Bankshares, Inc. and subsidiaries, at December 31, 1993 and 1992, and the
consolidated results of their operations and their cash flows for each of the
years in the three year period ended December 31, 1993, in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting principles and reporting policies followed by Investark
Bankshares, Inc. and its subsidiaries (the "Company") conform with generally
accepted accounting principles and with general practices within the financial
services industry. The following is a description of the more significant of
these policies:
 
  Principles of consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries, First Stuttgart Bank and Trust Company (formerly First
National Bank in Stuttgart), Stuttgart, Arkansas (100% owned) and of The Bank of
North Arkansas, Melbourne, Arkansas (99.7% owned). All significant intercompany
balances and transactions have been eliminated.
 
  Cash flows
 
     For purposes of reporting cash flows, cash and cash equivalents include
cash and due from banks, and federal funds sold.
 
  Investment securities
 
     Investment securities, except for investments in mutual funds, are stated
at cost adjusted for amortization of premiums and accretion of discounts.
Investments in mutual funds are carried at the lower of cost or market. Gains
and losses on the sale of investment securities are computed using the specific
identification method.
 
  Allowance for loan losses
 
     The allowance for loan losses is established through charges to expense and
is maintained at a level which, in management's judgement, is necessary to
provide for future losses from the current portfolios. This judgement is based
on analysis of the current and expected economic conditions, risk
characteristics of the loan portfolios and prior loan loss experience in
relation to loans outstanding.
 
  Interest on loans
 
     Interest on installment loans is recognized as income over the lives of the
loans by the sum-of-the-months-digits and simple interest methods. The results
of using the sum-of-the-months-digits method do not differ materially from those
obtained by using the interest method. Interest on other loans is recognized
based on the principal amounts outstanding. The accrual of interest on loans is
discontinued when, in the opinion of management, there is doubt as to the
ability of the borrower to pay interest or principal. The balances of non-
accrual loans were $474,067 and $446,379 at December 31, 1993 and 1992. Interest
previously accrued but uncollected on these loans was $148,031 and $51,142 at
December 31, 1993 and 1992.
 
  Premises and equipment
 
     Premises and equipment are stated at cost, less accumulated depreciation.
Depreciation is computed principally by the straight-line method.
 
  Real estate owned other than premises
 
     Real estate owned other than premises consists primarily of property
acquired in settlement of loans These properties are initially recorded at the
lower of cost or fair value as determined by appraisal at the date acquired.
Losses arising from such acquisitions are charged to the allowance for loan
losses. Carrying values are subsequently reduced through a charge to operations
when current appraisals indicate a decline in value.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Fair value is based on the estimated net amount realizable on disposition of the
property. Amounts included in other assets at December 31, 1993 and 1992, were
$142,874 and $1,241,534, respectively.
 
  Income taxes
 
     Provisions for income taxes are based on amounts reported in the statements
of income (after exclusion of non-taxable income such as interest on state and
municipal securities) and include deferred taxes on temporary differences in the
recognition of income and expense for tax and financial statement purposes.
Deferred taxes are computed using the liability method as prescribed in SFAS No.
109, "Accounting for Income Taxes."
 
  Off-balance-sheet financial instruments
 
     In the ordinary course of business the Company has entered into
off-balance-sheet financial instruments consisting of commitments to extend
credit, commitments under credit card arrangements, commercial letters of credit
and standby letters of credit. Such financial instruments are recorded in the
financial statements when they become payable.
 
  Trust Department assets
 
     In accordance with the usual practice of banks, property other than cash
deposits held by the Company's subsidiary bank's Trust Department in a fiduciary
or agency capacity for customers, is not included in the consolidated financial
statements.
 
  Reclassification
 
     Certain 1992 amounts have been reclassified to conform with the 1993
presentation.

NOTE 8: EMPLOYEE BENEFIT PLANS
 
     First Stuttgart Bank has a defined benefit pension plan which covers
substantially all its employees. The benefits are based on years of service and
the employee's compensation during the last five years of employment. The
funding policy is to contribute annually an amount that does not exceed the
maximum amount deductible for federal income tax purposes. Contributions are
intended to provide not only for benefits attributed to service to date but also
for those expected to be earned in the future.

     The weighted-average discount rate and the rate of increase in future
compensation levels used in determining the actuarial present value of the

long-term rate of return on assets was 7.0%.
 
     In connection with the merger with First United Bancshares, First Stuttgart
Bank is to terminate its defined benefit plan during 1994. Under generally
accepted accounting principles, if the net effect of the termination is a loss,
it should be recognized when the termination is probable and the effects are
reasonably estimable. Accordingly, a loss of $215,000 on the termination of this
plan is included in the accompanying 1993 statement of income.
 
     The Bank of North Arkansas has a defined contribution employee benefit
plan, qualified under IRC Section 401(k) that covers all employees, with the
exception of employees who are highly compensated. Contributions to the plan are
based on the total amount of salary reduction the employee elects to defer, a
discretionary matching contribution equal to a percentage of the amount the
employee elects to defer, which percentage will be determined each year by the
employer, and a discretionary amount determined each year by the employer. To
share in the matching and discretionary contribution, the employee must complete
a year of service and be actively employed on the last day of the Plan Year. The
amount of pension expense was $13,345 and $15,606 for 1993 and 1992,
respectively.

NOTE 9: DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:
 
Cash and due from banks and short-term investments:
     For these short-term items, the carrying amount is a reasonable estimate of
     fair value.
 
Investment securities:
     Fair values are based on quoted market prices, if available. If a quoted
     market price is not available, fair value is estimated using quoted market
     prices for similar securities.
 
Loans:
     The fair value of loans is estimated by discounting the expected future
     cash flows using current rates at which similar loans would be made to
     borrowers with similar credit ratings and for similar remaining maturities.
 
Deposit liabilities:
     The fair value of demand deposits, savings accounts and certain money
     market deposits is the amount payable on demand at the reporting date. The
     fair value of fixed-maturity certificates of deposit is estimated using the
     rates currently offered for deposits with similar remaining maturities.
 
Borrowed funds:
     For borrowings with fixed interest rates, fair value is estimated using the
     rates currently available to the Company's subsidiary banks for debt with
     similar terms and remaining maturities. For floating rate debt the fair
     value approximates the recorded liability.
 
Commitments to extend credit and letters of credit:
     The fair value of commitments is estimated using the fees currently charged
     to enter into similar arrangements, taking into account the remaining terms
     of the agreements and the present creditworthiness of the counterparties.
     For fixed rate loan commitments, fair value also considers the difference
     between current levels of interest rates and committed rates. The fair
     value of letters of credit is based on the fees currently charged for
     similar agreements or on the estimated cost to terminate them or otherwise
     settle the obligations with the counterparties at the reporting date.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 11: COMMITMENTS AND CONTINGENCIES
 
     The consolidated financial statements do not reflect various commitments
and contingent liabilities which arise in the normal course of the Company's
business and which involve elements of credit risk, interest rate risk and
liquidity risk. These commitments and contingent liabilities consist of
commitments to extend credit and letters of credit. A summary of the commitments
and contingent liabilities at December 31, 1993 and 1992 are summarized below:

                                                                $22,284,395    $18,846,737
                                                                -----------    -----------
                                                                -----------    -----------
</TABLE>
 
     Commitments to extend credit, credit card arrangements and letters of
credit all include some exposure to credit loss in the event of nonperformance
of the customer. The Company's credit policies and procedures for credit
commitments and financial guarantees are the same as those for extensions of
credit that are recorded in the consolidated financial statements. Because these
instruments have fixed maturity dates, and because many of them expire without
being drawn upon, they do not generally present any significant liquidity risk
to the Company.
 
     In the ordinary course of business, there are various legal proceedings
involving the Company and its subsidiaries, most of which are considered
litigation incidental to the conduct of business. These proceedings include,
among other matters, defense of routine corporate, employment, banking and
lender liability related litigation. Management, after consulting with legal
counsel and based on the facts available and proceedings to date, some of which
are preliminary, is of the opinion that the ultimate resolution of these
proceedings will not have a material adverse effect on the consolidated
financial position of the Company.
 
NOTE 12: CONCENTRATIONS OF CREDIT
 
     Substantially all of the Company's loans, commitments to loan and letters
of credit have been granted to customers in their trade area who are also
depositors of the Company. The concentrations of credit by type of loan are set
forth in Note 3. The distribution of commitments to extend credit approximates
the distribution of loans outstanding.
 
NOTE 13: DIVIDEND RESTRICTIONS
 
     As State Banks, First Stuttgart Bank and The Bank of North Arkansas are
each restricted in the amount of dividends they may pay in any year without
prior permission from the Arkansas Bank Commissioner to fifty percent of its net
income for the year. The Banks' ability to pay dividends is also restricted by
the minimum capital requirement of their regulatory agencies which require them
to maintain at least an 8.25% risk-based capital ratio.
 
NOTE 14: RELATED PARTY TRANSACTIONS
 
     Some of the directors and executive officers and the companies in which
they had a significant interest were customers of and had transactions with the
Company's subsidiary banks. Such transactions were made in the ordinary course
of the Banks' business on substantially the same terms and conditions, including
interest rates and collateral, as those prevailing at the same time for
comparable transactions with other customers and did not, in the opinion of
management, involve more than a normal credit risk or present other unfavorable
features. The aggregate amount of loans to such related parties amounted to
$2,212,481 and $3,345,252 at

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
December 31, 1993 and 1992, respectively. Transactions during 1993 included new
loans amounting to $2,459,497 and repayments amounting to $3,592,268.
 
NOTE 15: SUPPLEMENTAL CASH FLOW INFORMATION
 
     The Company paid $5,166,679 and $7,031,918 in interest on deposits and
other borrowings during 1993 and 1992, respectively, and income taxes of
$289,000 and $470,000 for 1993 and 1992.
 
NOTE 16: PENDING MERGER
 
     On December 17, 1993 the Company entered into an agreement to merge with
First United Bancshares, Inc. of El Dorado, Arkansas. Under the terms of this
agreement First United would acquire all of the outstanding stock of Investark
Bankshares, Inc. through issuance of First United common stock valued at
approximately $26,125,000. This transaction is expected to be consummated in the
first half of 1994.
 
NOTE 17: EFFECTS OF RECENTLY ADOPTED ACCOUNTING STANDARDS
 
     During 1993, the Financial Accounting Standards Board (FASB) issued SFAS
No. 114 (Accounting by Creditors for Impairment of a Loan) which becomes
effective beginning in 1995. This statement requires that impaired loans that
are within the scope of the Statement essentially be measured based on the
present value of expected future cash flows discounted at the loan's effective
rate, or as a practical expedient, at the loan's observable market price or the
fair value of the collateral if the loan is collateral dependent. Management has
not determined the effect this statement will have when adopted.
 
     In 1993, the Financial Accounting Standards Board (FASB) issued SFAS No.
115, (Accounting for Certain Investments in Debt and Equity Securities), that
becomes effective for fiscal years beginning after 1993. This Statement
addresses the accounting and reporting for investments in debt and certain
equity securities. Debt securities not classified as trading account securities
or investment securities expected to be held to maturity and all equity
securities will be classified as available for sale and are reported at fair
value, with net unrealized gains and losses reported, net of tax, as a separate
component of stockholders' equity. InvestArk will apply the new rules starting
in the first quarter of 1994 and believes the impact of adopting this statement
will not be material to its financial position or results of operations.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     This Agreement and Plan of Reorganization ("Agreement") is made as of
December 17, 1993 by and between First United Bancshares, Inc. ("United") and
InvestArk Bankshares, Inc. ("InvestArk").
 
     WHEREAS, InvestArk owns ninety nine and seven tenths percent (99.7%) of the
issued and outstanding shares of capital stock of The Bank of North Arkansas,
Melbourne, Arkansas ("North Arkansas") and one hundred percent (100%) of the
issued and outstanding shares of capital stock of First Stuttgart Bank & Trust
Company, Stuttgart, Arkansas ("First Bank"); and
 
     WHEREAS, United desires to acquire one hundred percent (100%) of the
capital stock of InvestArk (the "InvestArk Common Stock") upon the terms and
conditions hereinafter set forth through the merger of InvestArk with and into
United (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 United and InvestArk believe
that such proposed Merger and the exchange of shares of United Stock (as defined
in Section 2.01(a) hereof) for the InvestArk 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 short-term and long-term interests of their
respective corporations and shareholders; and
 
     WHEREAS, United and InvestArk 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,
United and InvestArk agree to effect the Merger of InvestArk with and into
United in accordance with the Arkansas Business Corporation Act (the "ABCA").
 
     1.02. Effective Time of the Merger. Subject to the provisions of the Merger
Agreements, articles of merger (the "Articles of Merger") shall be duly prepared
and executed by United and InvestArk and thereafter delivered to the Secretary
of State of Arkansas for filing, as provided in the ABCA, as soon as practicable
on or after the Closing Date (as defined in Section 1.03). The Merger shall
become effective upon the filing of the Articles of Merger with the Secretary of
State of Arkansas or at such time within two business days thereafter as is
provided in the Articles of Merger (the "Effective Time").
 
     1.03. Closing. The closing of the Merger (the "Closing") will take place at
the offices of United at a time and on a date (the "Closing Date") to be
specified in writing by the parties as soon as reasonably practicable after the
later to occur of all regulatory and other approvals and the expiration of all
waiting periods.
 
                                   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
InvestArk Common Stock, but subject to the rights of dissenting shareholders of
InvestArk:
 
          (a) Conversion of InvestArk Common Stock. One hundred percent of the
     issued and outstanding shares of InvestArk Common Stock shall be converted
     into the right to receive an aggregate amount of
 
                                      A-I-1
<PAGE>   72
 
     fully paid and nonassessable shares of voting common stock, $1.00 par
     value, of United determined by dividing $26,125,000.00 by the United
     Average Price as defined below. Notwithstanding the foregoing, the number
     of shares of United common stock to be issued shall not be less than
     885,593 and shall not be greater than 985,849. The number of shares of
     common stock of United so determined shall be referred to as the United
     Stock. The United Average Price shall be the average sales price per share
     of United 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. Each owner of InvestArk Common Stock shall be entitled to receive a
     pro rata portion of the United Stock based upon each owner's pro rata
     ownership of the total of outstanding shares of InvestArk Common Stock at
     the Effective Time. Fractional shares of United Stock shall not be issued.
     Any InvestArk 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 United Average Price.
 
          (b) Cancellation of Shares. All shares of InvestArk 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 United 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 United shall declare
     a stock dividend or subdivide, split up, reclassify or combine its shares
     of United common stock or make a distribution on United common stock of any
     security, appropriate adjustment or adjustments will be made in the
     conversion rate set forth in subsection (a).
 
          (d) Registration. The United 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 and Pension Plan. United shall have no
     liability to employees or directors of InvestArk, North Arkansas or First
     Bank for benefits of such employees or directors of InvestArk, North
     Arkansas or First Bank under the North Arkansas 401(k) plan or the First
     Bank pension plan. On or before the Closing Date, InvestArk shall and shall
     cause North Arkansas and First Bank to take all action necessary and
     appropriate to provide for termination of said plans and distribution of
     accrued benefits as of June 30, 1994. Such action shall specifically
     include, without limitation, entering into written agreements, in a form
     and for amounts satisfactory to United, with all participants in and
     beneficiaries of said plans in which each plan participant and beneficiary
     agrees (1) to accept such distribution in full satisfaction of all benefits
     due and rights under said plans; (2) that the participant's or
     beneficiary's distribution is equal to the present value of said
     participant's or beneficiary's benefits due or rights under the plans, and
     (4) to release InvestArk, North Arkansas and First Bank from any further
     liability or obligation under said 401(k) or pension plan.
 
     2.02. Approval By Shareholders. Consummation of the Merger shall be
contingent upon its approval by the legally required votes of the shares of
InvestArk Common Stock and United common stock at shareholders meetings duly
called for the purpose of voting on the Merger. In the event the number of
shares owned by InvestArk shareholders exercising dissenters' rights would or
could, in the written opinion of United's outside accountants, reasonably be
expected to cause the cash consideration paid by United to dissenters to
jeopardize United's ability to account for the Merger as a pooling of interests
then United shall have the right to terminate this Agreement. The Boards of
Directors of InvestArk and United shall recommend approval of the Merger to
their respective shareholders, unless such recommendation is inconsistent with
their fiduciary duties to the shareholders.

                         REPRESENTATIONS AND WARRANTIES
                                  OF INVESTARK
 
     InvestArk hereby represents and warrants to United the following:
 
     3.01. Organization, Standing and Power of InvestArk. InvestArk is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Arkansas and has all requisite corporate power and authority to
own, lease and operate its properties and to carry on its business as now being
conducted, except where the failure to have such power or authority would not
have a material adverse effect on the business, operations or financial
condition of InvestArk or any InvestArk Subsidiary (as hereinafter defined).
InvestArk is not qualified to do business in any other state or foreign
jurisdiction, and its ownership or leasing of property or the conduct of its
business does not require it to be so qualified, except where such failure to be
so qualified would not have a material adverse effect on the business,
operations or financial condition of InvestArk or any InvestArk Subsidiary.
InvestArk is registered as a bank holding company with the Federal Reserve Board
under the Bank Holding Company Act of 1956, as amended (the "BHC Act").
InvestArk has delivered to United true, accurate and complete copies of its
currently effective Articles of Incorporation and Bylaws, including all
amendments thereto.
 
     3.02. Ownership, Organization, Standing and Power of InvestArk
Subsidiaries. InvestArk directly and beneficially owns all of the shares of the
outstanding capital stock of First Bank and 99.7% of the outstanding capital
stock of North Arkansas. North Arkansas and First Bank are hereinafter called
collectively the "InvestArk Subsidiaries" or individually an "InvestArk
Subsidiary". North Arkansas and First Bank are InvestArk's only subsidiaries. No
equity securities of North Arkansas or First Bank are or may become required to
be issued by reason of any option, warrant, call, right or agreement of any
character whatsoever; there are outstanding no securities or rights convertible
into or exchangeable for shares of any capital stock of North Arkansas or First
Bank; and there are no other contracts, commitments, understandings or
arrangements by which either North Arkansas or First Bank is bound to issue

agreements to purchase or acquire any additional shares of its capital stock.
All of the shares of capital stock of North Arkansas and First Bank owned by
InvestArk are fully paid and nonassessable and are owned free and clear of any
claim, lien, encumbrance or agreement with respect thereto. North Arkansas and
First Bank are banking associations duly organized, validly existing and in good
standing under the laws of Arkansas, and have the corporate power and authority
to own or lease their properties and assets and to carry on their businesses as
they are now being conducted, except where the failure to have such power or
authority would not have a material adverse effect on the business, operations
or financial condition of North Arkansas, or First Bank. The deposits of North
Arkansas and First Bank are insured by the Federal Deposit Insurance Corporation
("FDIC") to the extent provided by law. InvestArk has delivered to United true,
accurate and complete copies of the currently effective Articles of
Incorporation and Bylaws of North Arkansas and First Bank, including all
amendments thereto. Except for $406,000.00 in capital stock of the Federal Home
Loan Bank of Dallas owned by First Bank and except for securities held in their
capacities as fiduciaries, North Arkansas and First Bank do not own
beneficially, directly or indirectly, any class of equity securities,
partnership interests or similar interests of any corporation, bank,
partnership, limited partnership, business trust, association or similar
organization. The authorized capital stock of North Arkansas consists of 100,000
shares of common stock, $25.00 par value, of which 80,000 shares are

outstanding and are owned by InvestArk. North Arkansas and First Bank or their
predecessor banks have been chartered as banking institutions for more than 10
years.
 
     3.03. Capital Structure of InvestArk. The authorized capital stock of
InvestArk consists of 5,000,000 shares of common stock, $10.00 par value, of
which 219,626 shares are outstanding, including 3,162 shares held by InvestArk
in its treasury. Neither InvestArk, North Arkansas nor First Bank has issued and
has outstanding bonds, debentures, notes or other indebtedness having the right
to vote (or convertible into securities having the right to vote) on any matters
on which shareholders may vote ("Voting Debt"). All
 
                                      A-I-3
<PAGE>   74
 
outstanding shares of InvestArk Common Stock are validly issued, fully paid,
nonassessable, and not subject to preemptive rights. There are no options,
warrants, calls, rights, or agreements of any character whatsoever to which
InvestArk, North Arkansas or First Bank is a party or by which InvestArk, North
Arkansas or First Bank is obligated to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock or any voting debt
securities or by which InvestArk, North Arkansas or First Bank is obligated to
grant, extend or enter into any such option, warrant, call, right or agreement.
Immediately before and after the Effective Time there will be no option,
warrant, call, right or agreement obligating InvestArk, North Arkansas or First
Bank to issue, deliver or sell, or cause to be issued, delivered or sold, any
shares of capital stock or obligating InvestArk, North Arkansas or First Bank to
grant, extend or enter into any such option, warrant, call, right or agreement.
 
     3.04. Authority. InvestArk has all requisite corporate power and authority
to enter into this Agreement and the Plan of Merger and, subject only to
approval of this Agreement and the Plan of Merger by the shareholders of
InvestArk and of applicable regulatory authorities, to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Plan of Merger and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of InvestArk's board of directors. This Agreement
and the Plan of Merger have been duly executed and delivered by InvestArk, and,
subject to such shareholder approval, each constitutes a valid and binding
obligation of InvestArk enforceable in accordance with its terms, except as the
enforceability of the Agreement may be subject to or limited by bankruptcy,
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
(with or without notice or lapse of time, or both) under, or give rise to a
right of termination, cancellation or acceleration of any obligation or the loss
of a material benefit under, or the creation of a lien, pledge, security
interest or other encumbrance on assets (any such conflict, violation, default,
right of termination, cancellation or acceleration loss or creation, a
"Violation"), pursuant to any provision of (a) the Articles of Incorporation or
Bylaws of InvestArk, North Arkansas or First Bank or (b) any loan or credit
agreement, note, mortgage, indenture, lease, or other agreement, obligation,
instrument, permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to InvestArk, North
Arkansas or First Bank or their respective properties or assets, except where
such violation would not have a material adverse effect on the business,
operations or financial condition of InvestArk or any InvestArk Subsidiary.
Other than in connection or in compliance with the provisions of the ABCA, the
Securities Act and the regulations thereunder, the Securities and Exchange Act
of 1934, as amended, and the rules and regulations thereunder (the "Exchange
Act"), the securities or blue sky laws of the various states, and consents,
authorizations, approvals, notices or exemptions required under the BHC Act, the
National Bank Act, Arkansas banking laws, and from other regulatory agencies, no
consent, approval, order or authorization of, or registration, declaration or
filing with, any court, administrative agency or commission or other
governmental authority or instrumentality, domestic or foreign (a "Governmental
Entity"), is required by or with respect to InvestArk, North Arkansas or First
Bank in connection with the execution and delivery of this Agreement and the
Plan of Merger by InvestArk or the consummation by InvestArk of the transactions
contemplated hereby and thereby.

     (b) Without limitation of the foregoing, InvestArk has no reserve allowance
for self-insured health and dental benefit claims and knows of no facts which
should cause it to create such a reserve.
 
     3.06. InvestArk Reports. InvestArk, North Arkansas and First Bank have

required to be made with respect thereto, that were and are required to be filed

Department (the "ASBD") and (iv) any other applicable securities, banking or
regulatory authorities (all such reports and statements are collectively

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

<PAGE>   77
 
shown on such returns, and the most recent InvestArk Financial Statements
reflect an adequate reserve for all taxes payable by InvestArk, North Arkansas
and First Bank accrued through the date of such financial statements. There has

InvestArk, North Arkansas or First Bank for over seven years. There is no

     3.11. Certain Agreements. Except as disclosed in Exhibit 3.11, neither

professional services, employment or other agreement not terminable at will
providing any term of employment, compensation, guarantee, or severance or
supplemental retirement benefit, (ii) union, guild or collective bargaining
agreement, (iii) agreement or plan, any of the benefits of which will be
increased, or the vesting of the benefits of which will be accelerated, by the
occurrence of any of the transactions contemplated by this Agreement or the
value of any of the benefits of which will be calculated on the basis of the
transactions contemplated by this Agreement, (iv) any stock option plan, stock
appreciation rights plan, restricted stock plan, stock purchase plan or similar
plan granting rights to acquire stock in InvestArk, North Arkansas or First
Bank, or (v) contract containing covenants which limit the ability of InvestArk,
North Arkansas or First Bank to compete in any line of business or with any
person or which involve any restriction of the geographical area in which, or
method by which, InvestArk, North Arkansas or First Bank may carry on its
business (other than as may be required by law or applicable regulatory
authorities). InvestArk, North Arkansas and First Bank shall terminate all
existing consulting, professional services and employment contracts, other than
at will employment contracts, and those agreements set forth in Exhibit 3.11, by

     3.12. Benefit Plans. (a) Exhibit 3.12 hereto lists (i) each employee bonus,
incentive, deferred compensation, stock purchase, stock appreciation right,
stock option and severance pay plan, (ii) each pension, profit sharing, stock
bonus, thrift, savings and employee stock ownership plan, and (iii) every other
employee benefit plan (within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") (collectively
"Benefit Plans"), which InvestArk, North Arkansas or First Bank maintains or to
which InvestArk, North Arkansas or First Bank contributes on behalf of current
or former employees. All of the plans and programs listed in Exhibit 3.12
(collectively, "InvestArk Benefit Plans") comply in all material respects with
all applicable requirements of ERISA and all other applicable federal and state
laws, including without limitation the reporting and disclosure requirements of
Part 1 of Title I of ERISA. With respect to the InvestArk Benefit Plans,
individually and in the aggregate, no event has occurred, and there exists no
condition or set of circumstances, in connection with which InvestArk, North
Arkansas or First Bank could be subject to any liability that is reasonably
likely to have a material adverse effect upon InvestArk, North Arkansas or First
Bank (except liability for benefits claims and funding obligations payable in
the ordinary course) under ERISA, the Code or any other applicable law. Each of
the InvestArk Benefit Plans that is intended to be a pension, profit sharing,
stock bonus, thrift, savings or employee stock ownership plan that is qualified
under Section 401(a) of the Internal Revenue Code of 1986, as amended (the
"Code"), has been determined by the IRS to qualify under Section 401(a) of the
Code, or an application for the
 
                                      A-I-7
<PAGE>   78
 
determination of such qualification will be made to the IRS under Section 401(b)
of the Code and the regulations thereunder, and there exist no circumstances
that would materially adversely affect the qualified status of any such
InvestArk Benefit Plan under that section. Each InvestArk Benefit Plan that is a
defined benefit pension plan has assets with an aggregate value that exceeds the
actuarially present value of its liability for accrued benefits as determined on
the basis of the actuarial assumptions used for the most recent actuarial
valuation of such Plan, no such Plan has incurred an accumulated funding
deficiency within the meaning of Section 412(a) of the Code, and no such Plan is
a "multi-employer plan" within the meaning of Section 3(37) of ERISA. There is
no pending or, to the best of InvestArk's knowledge, threatened litigation,
governmental proceeding or investigation against or relating to any InvestArk
Benefit Plan, and there is no reasonable basis for any material proceedings,
claims, actions or proceedings against any Plan. No "reportable event" (as
defined in Section 4043(b) of ERISA) (other than a "reportable event" for which
the 30-day notice requirement has been waived by the Pension Benefit Guaranty
Corporation) has occurred with respect to any InvestArk Benefit Plan, and no
InvestArk Benefit Plan has engaged in a "prohibited transaction" (as defined in
Section 406 of ERISA and Section 4975(c) of the Code) since the date on which
said sections became applicable to such Plan which could reasonably result in a
material liability.
 
     (b) InvestArk has delivered to United copies of (i) each InvestArk Benefit
Plan, (ii) the most recent summary plan descriptions of each InvestArk Benefit
Plan, (iii) each trust agreement, insurance policy or other instrument relating
to the funding of any InvestArk Benefit Plan, (iv) the most recent Annual
Reports (Form 5500 series) and accompanying schedules filed with the IRS or
United States Department of Labor with respect to each InvestArk Benefit Plan,
(v) the most recent determination letter issued by the IRS with respect to each
InvestArk Benefit Plan that is intended to qualify under Section 401 of the
Code, (vi) the most recent available financial statements for each InvestArk
Benefit Plan that has assets, (vii) the most recent actuarial report for any
InvestArk Benefit Plan that is a defined benefit pension plan, and if any such
Plan was amended subsequent to the date of such report, information about the
financial effects of such amendment and (viii) the most recent audited financial
statements for each InvestArk Benefit Plan for which audited financial
statements are required by ERISA.
 
     3.13. Insurance. InvestArk has delivered to United correct and complete
copies of all material policies of insurance of InvestArk, North Arkansas and
First Bank currently in effect, including, but not limited to, directors and
officers liability policies and blanket bond policies. Neither InvestArk, North
Arkansas nor First Bank has any liability for unpaid premiums or premium
adjustments not properly reflected on the InvestArk Financial Statements.

including, without limitation, properties under foreclosure, properties held by
United or a United subsidiary in its capacity as a trustee, or properties in

agreements set forth in this Agreement.

                                 PLAN OF MERGER
 
     This Plan of Merger, dated as of December 17, 1993 ("Plan of Merger"), by
and between First United Bancshares, Inc., an Arkansas corporation ("United"),
and InvestArk Bankshares, Inc., an Arkansas corporation ("InvestArk").
 
     WHEREAS, InvestArk is a corporation with authorized capital stock
consisting of 5,000,000 shares of common stock, $10.00 par value of which
219,122 shares of common stock, including 3,766 treasury shares, ("InvestArk
Common Stock") are validly issued and outstanding on the date hereof;
 
     WHEREAS, United is a corporation with authorized capital stock of
12,000,000 shares of common stock, $1.00 par value, of which 4,272,276 shares
are validly issued and outstanding on the date hereof;
 
     WHEREAS, United is a corporation duly organized and existing under the laws
of Arkansas;
 
     WHEREAS, concurrently with the execution and delivery of this Plan of
Merger, United and InvestArk have entered into an Agreement and Plan of
Reorganization (the "Agreement" and, together with this Plan of Merger, the
"Merger Agreements") that contemplates the merger of InvestArk with and into
United (the "Merger") upon the terms and conditions provided in this Plan of
Merger and the Agreement and pursuant to the Arkansas Business corporation Act
(the "ABCA");
 
     WHEREAS, the Boards of Directors of United and InvestArk deem it fair and
equitable to, and in the best short-term and long-term interests of, their
respective corporations and shareholders that InvestArk be merged with and into
United with United being the surviving corporation, and each such Board of
Directors has approved this Plan of Merger, has authorized its execution and
delivery, and has directed that this Plan of Merger and the Merger be submitted
to InvestArk and United shareholders for approval.
 
     NOW, THEREFORE, in consideration of the promises and the agreements herein
contained, the parties hereto adopt and agree to the following agreements, terms
and conditions relating to the Merger and the mode of carrying the same into
effect:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     1.01. The Merger. Subject to the terms and conditions of the Merger
Agreements, InvestArk will be merged with and into United, which will continue
as the surviving corporation, in accordance with and with the effect provided in
the ABCA.
 
     1.02. Effective Time of the Merger. Subject to the provisions of the Merger
Agreements, articles of merger (the "Articles of Merger") shall be duly prepared
and executed by United and InvestArk and thereafter delivered to the Secretary
of State of the State of Arkansas for filing, as provided in the ABCA, as soon
as practicable on or after the Closing Date (as defined in the Agreement). The
Merger shall become effective upon the filing of the Articles of Merger with the
Secretary of the State of Arkansas or at such time within two business days
thereafter as is provided in the Articles of Merger (the "Effective Time").
 
     1.03. Effects of the Merger. (a) At the Effective Time, (i) the separate
existence of InvestArk shall cease and InvestArk shall be merged with and into
United (United and InvestArk are sometimes referred to herein as the
"Constituent Corporations" and United is sometimes referred to herein as the
"Surviving Corporation"), (ii) the Articles of Incorporation of United in effect
as of the Effective Time (the "Articles") shall be the Articles of Incorporation
of the Surviving Corporation, and (iii) the Bylaws of United in effect as of the
Effective Time (the "Bylaws") shall be the Bylaws of the Surviving Corporation.
 
     (b) At and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises of a public as well as
of a private nature, and be subject to all the restrictions, disabilities and
duties of each of the Constituent Corporations; and all and singular rights,
privileges, powers and
<PAGE>   95
 
franchises of each of the Constituent Corporations, and all property, real,
personal and mixed and all debts due to either of the Constituent Corporations
on whatever account, as well as for stock subscriptions and all other things in
action or belonging to each of the Constituent Corporations, shall be vested in
the Surviving Corporation; and all property, rights, privileges, powers and
franchises, and all and every other interest shall be thereafter as effectually
the property of the Surviving Corporation as they were of the Constituent
Corporations, and the title to any real estate vested by deed or otherwise, in
either of the Constituent Corporations, shall not revert or be in any way
impaired; but all rights of creditors and all liens upon any property of either
of the Constituent Corporations shall be preserved unimpaired, and all debts,
liabilities and duties of the Constituent Corporations shall thenceforth attach
to the Surviving Corporation, and may be enforced against it to the same extent
as if said debts and liabilities had been incurred by it. Any action or
proceeding, whether civil, criminal or administrative, pending by or against
either Constituent Corporation shall be prosecuted as if the Merger had not
taken place, and the Surviving Corporation may be substituted as a party in such
action or proceeding in place of any Constituent Corporation.
 
                                   ARTICLE II
 
                    EFFECT OF THE MERGER ON THE COMMON STOCK
                        OF THE CONSTITUENT CORPORATIONS;
                            EXCHANGE OF CERTIFICATES
 
     2.01. Conversion of InvestArk 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 InvestArk Common Stock, but subject to the rights of dissenting
shareholders of InvestArk:
 
     (a) Conversion of InvestArk Common Stock. The issued and outstanding shares
of InvestArk 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 InvestArk 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, United 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
United (the "Exchange Agent") for the benefit of the holders of shares of
InvestArk Common Stock, for exchange in accordance with this Article II through
the Exchange Agent, the number of shares of United common stock and cash (the
"Exchange Fund") to be paid pursuant to Section 2.01 in exchange for shares of
InvestArk 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 InvestArk Common Stock (the "Certificates")
whose shares were converted into the right to receive shares of United 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 United may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the United 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 United, 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 shares of United 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
<PAGE>   96
 
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 United
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.
 
     (d) No Further Ownership Rights in InvestArk Common Stock. The
consideration paid upon the surrender of shares of InvestArk 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 InvestArk
Common Stock, and there shall be no further registration of transfers on the
stock transfer books of the Surviving Corporation of the shares of InvestArk
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 InvestArk for six months after the
Effective Time shall be delivered to United, upon demand, and any shareholders
of InvestArk who have not theretofore complied with this Section 2.02 shall
thereafter look only to United for payment of the United common stock and cash
due for their InvestArk stock.
 
     (f) No Liability. Neither United nor InvestArk shall be liable to any
holder of shares of InvestArk Common Stock for shares of United common stock or
cash from the Exchange Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.
 
                                  ARTICLE III
 
                       CONDITIONS; TERMINATION; AMENDMENT
 
     3.01. Conditions to the Merger. Consummation of the Merger is conditional
upon the fulfillment or waiver of the conditions precedent set forth in Article
VII of the Agreement.
 
     3.02. Termination. This Plan of Merger may be terminated and the Merger
abandoned by mutual consent of the respective Boards of Directors of InvestArk
and United at any time prior to the Effective Time. If the Agreement is
terminated in accordance with Article IX thereof, then this Plan of Merger will
terminate simultaneously and the Merger will be abandoned without further action
by InvestArk or United.
 
     3.03. Amendment. Subject to the next following sentence, this Plan of
Merger may be amended by the parties hereto by action taken or authorized by
their respective Boards of Directors at any time before the Closing Date. This
Plan of Merger may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto.
 
     3.04. Extension; Waiver. At any time prior to the Closing Date, United and
InvestArk, by action taken or authorized by their respective Board of Directors,
may, to the extent legally allowed, (i) extend the time for the performance of
any of the obligations or other acts of the other party hereto and (ii) waive
compliance by the other with any of the agreements or conditions contained
herein. Any agreement on the part of a party hereto to any such extension or
waiver shall be valid only if set forth in a written instrument on behalf of
such party.
 
                                   ARTICLE IV

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
InvestArk Bankshares, Inc. an Arkansas Corporation ("InvestArk"). Pursuant to
the merger (the "Merger") of InvestArk with and into 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 December
17, 1993, 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 issuance of the Shares to me pursuant to the
Merger has been registered under the Act in the Registration Statement on SEC
Form 5-4, as amended, Registration No.           ("Registration Statement") as
filed with the SEC, receipt of a copy of which Registration Statement is hereby
acknowledged. 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 [  ]nless (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 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, or 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 the Shares, unless United has made public disclosure of
financial results reflecting 30 days' of post-Merger combined operations of
InvestArk and First United within the meaning of Section 201.01 of the SEC's
Codification of Financial Reporting Policies. In addition, I hereby represent
and warrant to First United that I have not made any sales of InvestArk or
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 United or InvestArk 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
InvestArk.
 
     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 volume
and other
<PAGE>   105
 
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 [ ]egister
(except to the extent as expressed in that Certain Shareholders Agreement, dated
December 17, 1993) 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 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 taxpayer identification number and SEC file number.
 
     The information and documents described or referred to above were furnished
to me before my right to acquire the Shares became fixed.
 
                                            Very truly yours,

     sixty (60) days after the date set for demanding payment; or

                          JUDICIAL APPRAISAL OF SHARES
 
4-27-1330. COURT ACTION.
 
     A. If a demand for payment under sec. 4-27-1328 remains unsettled, the
corporation shall commence a proceeding within sixty (60) days after receiving
the payment demand and petition the court to determine the fair value of the
shares and accrued interest. If the corporation does not commence the proceeding
within the sixty-day period, it shall pay each dissenter whose demand remains
unsettled the amount demanded.
 
     B. The corporation shall commence the proceeding in the circuit court of
the county where the corporation's principal office (or, if none in this state,
its registered office) is located. If the corporation is a foreign corporation
without a registered office in this state, it shall commence the proceeding in
the county in this state where the registered office of the domestic corporation
merged with or whose shares were acquired by the foreign corporation was
located.
 
     C. The corporation shall make all dissenters (whether or nor residents of
this state) whose demands remain unsettled parties to the proceeding as in an
action against their shares and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.
 
     D. The jurisdiction of the court in which the proceeding is commenced under
subsection B. of this section is plenary and exclusive. The court may appoint
one (1) or more persons as appraisers to receive evidence and recommend decision
on the question of fair value. The appraisers have the powers described in
 
                                     A-III-5
<PAGE>   112
 
the order appointing them, or in any amendment to it. The dissenters are
entitled to the same discovery rights as parties in other civil proceedings.
 
     E. Each dissenter made a party to the proceeding is entitled to judgment:
 
          (1) For the amount, if any, by which the court finds the fair value of
     his shares, plus interest, exceeds the amount paid by the corporation; or
 
          (2) For the fair value, plus accrued interest, of his after-acquired
     shares for which the corporation elected to withhold payment under
     sec. 4-27-1327.
 
HISTORY.  Acts 1987, No. 958, sec. 64-1313.
 
4-27-1331. COURT COSTS AND COUNSEL FEES.
 
     A. The court in an appraisal proceeding commenced under sec. 4-27-1330
shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court. The court shall
assess the costs against the corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily, vexatiously, or not
in good faith in demanding payment under sec. 4-27-1328.
 
     B. The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:
 
          1. Against the corporation and in favor of any or all dissenters if
     the court finds the corporation did not substantially comply with the
     requirements of 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.
