                                 PROXY STATEMENT

                            LIBERTY BANCSHARES, INC.
                                   PROSPECTUS

    Sac River Valley Bank, a Missouri banking corporation ("Sac River") is
providing this Proxy Statement-Prospectus to its shareholders in connection with
the solicitation of proxies by the Sac River Board of Directors for use at a
special meeting of the shareholders of Sac River (the "Special Meeting"). The
Special Meeting will convene on November 10, 1998, at 9:00 a.m., local time, in
the main office of Sac River located at 14 Public Square, Stockton, Missouri,
including any adjournment or postponement thereof, for the purpose of
considering and voting upon the matters set forth in the preceding Notice of
Special Meeting of the Shareholders of Sac River, as more fully described in
this Proxy Statement-Prospectus.

    Liberty Bancshares, Inc. ("Bancshares"), has filed a Registration Statement
on Form S-4 (together with all amendments and exhibits, the "Registration
Statement") with the Securities and Exchange Commission (the "Commission")
pursuant to the Securities Act of 1933, as amended (the "Securities Act"),
covering up to 355,160 shares of common stock of Bancshares, par value $1 per
share ("Bancshares Common Stock"), to be issued under the Agreement and Plan of
Merger, dated as of June 18, 1998, between Bancshares, Liberty Bank, a Missouri
banking corporation ("Liberty"), and Sac River (the "Merger Agreement"). The
Merger Agreement provides that, subject to the approval of the holders of shares
of common stock of Sac River at the Special Meeting and the satisfaction (or
waiver, to the extent that such waiver is permitted by law) of other conditions
to closing contained in the Merger Agreement, Sac River will merge with and into
Liberty, and Liberty will be the surviving corporation (the "Merger"). In the
Merger each issued and outstanding share of common stock of Sac River ("Sac
River Common Stock") (other than shares held by persons who do not vote in favor
of the Merger and who properly exercise their dissenter's rights by following
the procedures required under Missouri Revised Statutes Section 362.730, as
amended) shall be converted into the right to receive cash in the amount of
$485.70 per share plus, at the election of the shareholder, cash in the amount
of $1,050 per share, or 35.516 shares of the common stock of Bancshares, or a
combination of the two, as provided in the Merger Agreement. Accompanying this
Prospectus/Proxy Statement is the Election Notice on which Sac River
shareholders may elect to receive the Optional Per Share Cash Amount, Bancshares
Common Stock, or a combination of each. Sac River shareholders may submit the
Election Notice to Sac River at any time before the vote on the Merger commences
at the Special Meeting. Sac River shareholders may change their election at any
time before the commencement of the vote or during any adjournment of the
Special Meeting. See "Summary - The Merger" and "THE MERGER - Terms of the
Merger." The aggregate value of the cash and stock consideration in the Merger
is $15,357,000. After the Merger, the Sac River shareholders will own between
260,450 and 355,160 shares of Bancshares Common Stock (or between 33.8% and
41.0% of the issued and outstanding shares of Bancshares Common Stock),
depending upon the number of Sac River shareholders who elect to receive cash
rather than shares of Bancshares Common Stock in exchange for their Sac River
Common Stock and taking into account the limitation on the aggregate amount of
Optional Per Share Cash Amount. Under the Merger Agreement, the total cash
payable by Bancshares with respect to the Optional Per Share Cash Amount cannot
exceed $2,800,000, less cash paid in lieu of fractional shares. If the total
cash payable by Bancshares with respect to the Optional Per Share Cash Amount
exceeds $2,800,000, and Sac River cannot persuade enough shareholders to change
their election to reduce the total cash payable with respect to the Optional Per
Share Cash Amount to $2,800,000, the parties will not be obligated to conclude
the Merger. See "RISK FACTORS - Risks Associated with Limit on Optional  Per
Share Cash Amount," and "The Merger - Terms of the Merger" and "The Merger
Conditions to the Merger." This Proxy Statement-Prospectus also constitutes the
prospectus of Bancshares filed as part of the Registration Statement. See
"AVAILABLE INFORMATION." Sac River will begin mailing this Proxy
Statement-Prospectus and accompanying form of proxy to shareholders of Sac River
on or about October 10, 1998. IN ADDITION TO THE OTHER INFORMATION CONTAINED
HEREIN, SAC RIVER SHAREHOLDERS SHOULD CAREFULLY REVIEW THE "RISK FACTORS"
SECTION OF THIS PROXY STATEMENT-PROSPECTUS ON PAGES 8 TO 12.

THE SPECIAL MEETING

         Sac River will hold the Special Meeting at its main office located at
14 Public Square, Stockton, Missouri on November 10, 1998, at 9:00 a.m., local
time, for the purpose of considering and voting upon the Merger Agreement. Only
holders of record of Sac River Common Stock at the close of business on
September 25, 1998 (the "Record Date") will receive notice of, and may vote at,
the Special Meeting. As of the Record Date, 10,000 shares of Sac River Common
Stock were issued and outstanding. See "THE SPECIAL MEETING - Introduction;
Purpose; Record Date; Votes Required." 

THE MERGER

         The Merger Agreement provides for the merger of Sac River with Liberty.
Liberty will be the surviving corporation. The separate existence of Sac River
will cease after the Merger.

         Except as described under "THE MERGER - Terms of the Merger," upon
consummation of the Merger, each outstanding share of Sac River Common Stock
will be converted into the right to receive from Bancshares cash in the amount
of Four Hundred Eighty-Five Dollars and 70/100 ($485.70) per share (the
"Mandatory Per Share Cash Amount") plus, at the election of the shareholder,
cash in the amount of $1,050 per share or Bancshares Common Stock at a
conversion ratio of 35.516 shares of Bancshares Common Stock for each share of
Sac River Common Stock. Sac River shareholders can also elect to receive cash
for some of their shares of Sac River Common Stock and Bancshares Common Stock
for the balance. If a shareholder fails to make an election, all of the Sac
River Common Stock held by the shareholder will be exchanged for Bancshares
Common Stock. Bancshares' payment of the Mandatory Per Share cash amount
requires approval by the FRS Board. See "THE MERGER-Terms of the Merger," and
"THE MERGER - Certain Federal Income Tax Consequences of the Merger."

         Sac River shareholders may make their election by completing and
returning to Sac River the "Election Notice" that accompanies this
Prospectus/Proxy Statement, which they may return by mail or delivery to Sac
River at any time before the commencement of the vote on the Merger at the
Special Meeting. Sac River shareholders may change their Election Notice at any
time before the commencement of the Merger vote at the Special Meeting or during
any adjournment of the Special Meeting by delivering a new Election Notice to
Sac River. For additional information about the Election Notice, see "THE
MERGER" - Terms of the Merger."

RISK FACTORS

         There are certain risks associated with the proposed Merger as more
fully described in the section of this Proxy Statement-Prospectus entitled "RISK
FACTORS." These risks include the lack of any established trading market for
Bancshares Common Stock and the risks associated with Sac River's and Liberty's
commercial lending activities. There is also no established public trading
market for the shares of Sac River Common Stock. To the knowledge of the
management of Bancshares, the most recent trade involving shares of the
Bancshares Common Stock occurred in February 1997. To the knowledge of the
management of Sac River, the most recent trade involving shares of the Sac River
Common Stock occurred in February 1998. Due to the lack of an active trading
market for the shares of Bancshares, the shareholders of Sac River may be unable
to resell the shares of Bancshares Common Stock to be issued in the Merger.
Affiliates of Sac River and Bancshares will be subject to additional limitations
on resales

                                        2

<PAGE>   15






         (v)      if there is a material breach of the representations and
                  warranties of Sac River or Bancshares.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF SAC RIVER

         The Board of Directors of Sac River has unanimously approved the Merger
Agreement and the Merger. The Board of Directors of Sac River believes that the
Merger is fair and in the best interests of the shareholders of Sac River and
recommends a vote FOR the approval of the Merger. For a discussion of the
factors considered by the Board of Directors of Sac River in reaching its
conclusions, see "THE MERGER - Reasons of the Board of Directors of Sac River
for Approving the Merger; Recommendation of the Board of Directors of Sac
River."

FEDERAL INCOME TAX CONSEQUENCES

         The consummation of the Merger is conditioned upon, among other things,
the opinion of Husch & Eppenberger, LLC, counsel to Bancshares and Liberty, that
the Merger will qualify as a reorganization within the meaning of Section 368 of
the Internal Revenue Code of 1986, as amended, for federal income tax purposes.
Based on that opinion, the principal federal income tax results of the Merger
will be as follows: (1) neither Sac River, Liberty, nor Bancshares will
recognize gain or loss as a result of the Merger; and (2) no Sac River
shareholder will recognize any gain or loss (other than gain with respect to
cash received in the Merger) upon the exchange of their Sac River Common Stock
for Bancshares Common Stock. However, the federal income tax considerations
related to the Merger may be different for particular types of Sac River
shareholders or in light of each Sac River shareholder's particular
circumstances. Consequently, Sac River shareholders are urged to consult their
own tax advisers concerning the federal income tax considerations that may be
relevant to them in connection with the Merger, and in particular the character
of the income recognized upon the receipt of cash in the Merger, as well as the
application to them of any state, local, foreign, or other tax laws. See "THE
MERGER - Certain Federal Income Tax Considerations."

REGULATORY MATTERS

         The FRS Board, the Division of Finance and the FDIC must approve the
Merger. Sac River and Bancshares do not have to conclude the Merger if the terms
and conditions of these regulatory approvals are not reasonably satisfactory to
them. See "THE MERGER - Regulatory Approvals."

MANAGEMENT OF SAC RIVER AND LIBERTY FOLLOWING CONSUMMATION OF MERGER

         After the consummation of the Merger, all of the existing directors of
Sac River and Bancshares will be directors of Bancshares. The existing officers
of Liberty will continue in their present positions and the officers of Sac
River will become officers of Liberty. In addition, Garry L. Robinson will serve
as the Executive Vice-President of Liberty and the Executive Vice-President of
Bancshares.

CERTAIN RELATIONSHIPS AND RELATED STOCK OWNERSHIP

         No directors, officers, or principal shareholders of Sac River own
shares of Bancshares Common Stock. Richard A. Pendleton, a director of Liberty
and Bancshares, is co-trustee of the Anise C. Brasher Revocable Trust U/T/A
dated August 1, 1995, which owns shares of Sac River Common Stock. No other

                                        5

<PAGE>   16
directors, officers or principal shareholders of Bancshares own shares of Sac
River Common Stock. Sac River has made loans to certain directors of Bancshares
in the ordinary course of Sac River's business. Sac River has also purchased
participations in loans originated by Liberty. See "CERTAIN RELATIONSHIPS AND
RELATED TRANSACTIONS-Directors of Bancshares, Loan Participation."

INTERESTS OF SAC RIVER OFFICES AND DIRECTORS IN THE
MERGER THAT DIFFER FROM THE INTERESTS OF SHAREHOLDERS

         Sac River directors and officers who are also Sac River shareholders
have certain interests in the Merger that differ from or are in addition to
those of Sac River shareholders. These include:

         --   Sac River directors will become members of Bancshares Board of
              Directors and as such will receive $200 per Board and Board Loan
              Committee Meeting they attend.

         --   Sac River officers will become officers of Liberty and will
              receive compensation as such. Garry Robinson, currently president
              of Sac River, will continue to receive salary and bonus under his
              existing employment agreement. See "BUSINESS OF SAC RIVER --
              Compensation of Sac River's Management."

         --   Former Sac River officers who become key employees of Liberty will
              be entitled to participate in Bancshares' Incentive Stock Option
              Plan. See "THE MERGER -- Effect on Employee Benefit Plans."

         --   Former Sac River officers will be able to participate in Liberty's
              401(k) plan. See "THE MERGER -- Effect on Employee Benefit
              Plans."

COMPARISON OF SHAREHOLDERS' RIGHTS

         Bancshares is a corporation organized under the laws of the State of
Missouri, and Chapter 351 of the Missouri Revised Statutes, the Articles of
Incorporation of Bancshares, and the by-laws of Bancshares govern the rights of
Bancshares shareholders. Sac River is a state chartered banking corporation
organized under Missouri Revised Statutes Chapter 362, and that statutory
section, the Articles of Association of Sac River, and the by-laws of Sac River
govern the rights of Sac River shareholders. There are relatively few
differences in shareholder rights for shareholders of Bancshares and Sac River
under the governing Missouri statutes. See "COMPARISON OF SHAREHOLDER RIGHTS."

ACCOUNTING TREATMENT OF THE MERGER

         Under generally accepted accounting principles, the Merger will be
treated as a purchase by Bancshares. See "THE MERGER - Accounting Treatment."

SELECTED CONSOLIDATED FINANCIAL DATA OF BANCSHARES

         The following table sets forth, on an historical basis, certain
selected consolidated financial data for Bancshares. Shareholders should read

HISTORICAL AND PRO FORMA COMPARATIVE PER SHARE DATA

         The following table sets forth per share data of Bancshares and Sac
River on both a historical basis and on a pro forma basis. Sac River
shareholders should read this table in conjunction with the historical
consolidated financial statements and notes thereto for Bancshares and Sac River
contained in this Proxy Statement-Prospectus. Pro forma combined and equivalent
pro forma per share data reflect the combined results of Bancshares and Sac
River presented as though they were one company for all periods shown.
Equivalent pro forma per share amounts are calculated by multiplying the pro
forma income per share and the pro forma book value per share of Bancshares by
the exchange ratio so that such per share amounts are equated to the respective
values for one share of Sac River. The pro forma amounts do not include
adjustments for estimated operating efficiencies or revenue enhancements, if
any, resulting from the Merger. The following pro forma and equivalent pro forma
information is based on the Exchange Ratio of 35.516 shares of Bancshares Common
Stock for each share of Sac River Common Stock. The equivalent pro forma data
does not include cash of $485.70 per share that will be received for each share
of Sac River Common Stock outstanding.

                                                  RISK FACTORS

LACK OF TRADING MARKET

         There is no established public trading market for the shares of
Bancshares Common Stock or Sac River Common Stock. Before the Effective Time of
the Merger, the sale or exchange of Bancshares Common Stock has been and until
the Merger is effective will be substantially restricted by the terms of a Stock
Purchase Agreement entered into by Bancshares' shareholders on May 1, 1995. To
the knowledge of Bancshares's management, the most recent trade involving shares
of Bancshares Common Stock occurred in February 1997 at a price of $10.78 per
share. To the knowledge of Sac River's management, the most recent trade
involving shares of Sac River Common Stock occurred in February 1998 at a price
of $1,400 per share (in a transaction between a Sac River director and a
Bancshares director with knowledge of the possible Merger). Earlier transactions
in Sac River Common Stock have been at prices under $1,000 per share. Since
there is no active trading market for the shares of Bancshares, the shareholders
of Sac River may be unable to resell the shares of Bancshares Common Stock to be
issued in the Merger. Additional restrictions on resale will apply to affiliates
of Sac River and Bancshares. See "THE MERGER-Resales of Bancshares Common Stock
Issued in the Merger."


RISKS ASSOCIATED WITH LIMIT ON OPTIONAL PER SHARE AMOUNT


         There is a possibility that Sac River shareholders will not receive all
of the cash that he or she actually elects or that the Merger will not be
consummated. Under the Merger Agreement, each shareholder of Sac River will
receive $485.70 per share of Sac River Common Stock, plus at the election of the
shareholder, cash in the amount of $1,050 per share (the "Optional Per Share
Cash Amount"), the right to receive 35.516 shares of Bancshares Common Stock, or
a combination of cash and shares. The total cash payable by Bancshares as the
Optional Per Share Amount to all shareholders of Sac River cannot exceed
$2,800,000 less cash distributed in lieu of fractional shares. This limitation
is necessary to permit the tax free treatment of the exchange of shares of Sac
River Common Stock for shares of Bancshares Common Stock. See "The
Merger-Federal Income Tax Consequences of the Merger." If enough Sac River
shareholders elect to receive the Optional Per Share Cash Amount so that the
total cash payable by Bancshares with respect to the Optional Per Share Cash
Amount exceeds $2,800,000, Sac River will attempt to have shareholders change
their election. If enough shareholders do not change their election to reduce
the total cash payable by Bancshares as to the Optional Per Share Cash Amount to
$2,800,000 (less cash paid in lieu of

                                       10


<PAGE>   21
fractional shares), the parties do not have an obligation to consummate the
Merger. See "The Merger - Terms of the Merger" and "The Merger - Conditions to
the Merger."

RISKS ASSOCIATED WITH COMMERCIAL REAL ESTATE, BUSINESS AND CONSTRUCTION LOANS

         The operations of Sac River and Liberty include funding commercial real
estate, business, and construction loans. Commercial real estate and commercial
lending involve significant additional risks compared with one-to-four family
residential mortgage lending, and therefore, for many banks account for a
disproportionate share of delinquent loans and real estate owned through
foreclosure. These kinds of loans generally involve a larger loan balance to
single borrowers or groups of related borrowers than does residential lending,
and repayment of the loan depends in part on the underlying business and
financial condition of the borrower and is more susceptible to adverse future
developments. If the cash flow from an income-producing property is reduced (for
example, because leases are not obtained or renewed), the borrower's ability to
repay the loan may be materially impaired. These risks can be significantly
affected by considerations of supply and demand in the market for office,
manufacturing, and retail space and by general economic conditions. As a result,
commercial real estate and business loans are likely to be subject, to a greater
extent than residential property loans, to adverse conditions in the economy
generally.

         Construction loans are, in general, subject to the same risks as
commercial real estate loans, but involve additional risks due to uncertainties
inherent in estimating construction costs, delays arising from labor problems,
shortages of material, uncertain marketability of a completed project and other
unpredictable contingencies that make it relatively difficult to determine
accurately the total loan funds required to complete a project or the value of
the completed project. Banks advance construction loan funds on the security of
the project under construction, which is of uncertain value prior to the
completion of construction. When a construction project encounters cost
overruns, marketing or other problems, it may become necessary, in order to
sustain the project and to preserve collateral values, for the lender to advance
additional funds and to extend the maturity of its loan. In a declining market,
there is no assurance that this strategy will successfully enable the lender to
recover outstanding loan amounts and interest due. Moreover, foreclosing on such
properties results in administrative expense and substantial delays in recovery
of outstanding loan amounts and provides no assurance that the lender will
recover all monies due to it, either by developing the property (subject to
regulatory limitations and to the attendant risks of development) or by selling
the property to another developer.

         As of June 30, 1998, Sac River's gross loan portfolio totaled $64.9
million, or 71.4% of assets, of which $16.1 million, or 24.8%, consisted of
one-to-four family residential mortgages, $34.8 million, or 53.6%, consisted of
commercial real estate loans, $6.6 million, or 10.2%, consisted of
non-agricultural business loans, $3.3 million, or 5.0%, consisted of
agricultural loans, and $4.1 million, or 6.4%, consisted of consumer loans. As
of June 30, 1998, Liberty's gross loan portfolio totaled $79.9 million, or 71.7
of assets, of which $13.8 million, or 17.3%, consisted of residential real
estate loans, $16.2 million, or 20.2%, consisted of non-agricultural business
loans, $38.6 million, or 48.3%, consisted of commercial real estate loans, $10.8
million, or 13.5%, consisted of consumer loans and $0.5 million, or 0.6%
consisted of agricultural loans. See "Management's Discussion and Analysis of

of Liberty Bancshares - Loan Portfolio" and "Management's Discussion and
Analysis of Consolidated Financial Conditions and Results of Operations of Sac
River - Loan Portfolio."

RISKS RELATED TO GEOGRAPHIC CONCENTRATION OF LENDING OPERATIONS

         Liberty's and Sac River's lending operations are concentrated primarily
in southwestern Missouri. As a result, the post-merger financial condition and
results of Liberty's operations will reflect the effects of changes in the
business cycle and downturns in the economy of the region, as well as the state
and the nation. In an economic downturn, banks tend to experience a run-off in
deposits. If economic conditions worsen after the Merger, Liberty may not be
able to originate the same volume of high quality loans. See "Business of Sac
River - Competition" and "Business of Liberty - Competition."

EFFECT OF CHANGES IN INTEREST RATES

         Bancshares' operating results after the Merger will depend to a large
extent on Liberty's net interest income, which is the difference between its
interest income on interest-earning assets and its interest expense on
interest-bearing liabilities. Rapid changes in interest rates may adversely
affect Liberty's net interest income. Interest rates are highly sensitive to
many factors, including governmental monetary policies and domestic and
international economic and political conditions. Conditions such as inflation,
recession, unemployment, money supply, international economic difficulties, and
other factors beyond Bancshares' control may also affect interest rates.

         Interest rate risk arises from mismatches (i.e. the interest
sensitivity gap) between repricing or maturity characteristics of assets and
liabilities and may be measured in terms of the ratio of the cumulative interest
sensitivity gap to total assets. More assets repricing or maturing than
liabilities over a given time frame is considered asset-sensitive and is
reflected as a positive gap, and more liabilities repricing or maturing than
assets over a given time frame than is considered liability-sensitive and is
reflected as a negative gap. An asset-sensitive position (i.e., a positive gap)
will generally enhance earnings in a rising interest rate environment and
negatively impact earnings in a falling interest rate environment, while a
liability-sensitive position (i.e., a negative gap) will generally enhance
earnings in a falling interest rate environment and negatively impact earnings
in a rising interest rate environment. Fluctuations in interest rates are not
predictable or controllable. At December 31, 1997, on a pro forma basis giving
effect to the Merger, Bancshares' pro forma interest-earning assets which were
estimated to mature or reprice within one year were less than Bancshares'
interest-bearing liabilities which were estimated to mature or reprice within
one year by $6.7 million for a negative one year gap position of 4.0%.

         Bancshares intends to structure its asset and liability management
strategies to mitigate the impact of changes in interest rates and, in
particular, intends to manage its interest rate risk through not holding
long-term fixed rate paper, and matching length of deposits (CD's) to length of
loans. Initially, it is expected that Liberty will continue its asset liability
management strategies. There can be no assurances, however, of Bancshares'
ability to continue to achieve positive net interest income. See "Management's
Discussion and Analysis of Financial Conditions and Results of Operations of
Liberty Bancshares."

ASSET QUALITY

                                       12
<PAGE>   23
         Industry experience indicates that a portion of a bank's loans will
become delinquent and that a portion of the delinquent loans will require
partial or entire charge-off. Regardless of the underwriting criteria that a
lender uses, it may experience losses as a result of various factors beyond its
control, including, among others, changes in market conditions affecting the
value of security and problems affecting the credit of the borrower. Sac River's
and Liberty's determination of the adequacy of their respective allowances for
possible loan losses is based on various considerations, including an analysis
of the risk characteristics of various classifications of loans, previous loan
loss experience, specific loans which would have loan loss potential,
delinquency trends, estimated fair value of the underlying collateral, current
economic conditions, the view of outside regulators, and geographic and industry
loan concentration. If, however, delinquency levels were to increase as a result
of adverse general economic conditions, particularly in southwestern Missouri
where Sac River's and Liberty's loan operations are concentrated, the loan loss
reserve determined by the two banks may not be adequate. There can be no
assurance that Liberty's allowance after the Merger will be adequate to cover
loan losses or that either bank will not experience losses in its loan
portfolios that may require significant increases to its allowance for possible
loan losses in the future. See "Management's Discussion and Analysis of
Financial Conditions and Results of Operations of Liberty Bancshares - Provision
for Loan Losses" and "Management's Discussion and Analysis of Financial
Conditions and Results of Operations of Sac River - Provision for Loan Losses."

RISKS ASSOCIATED WITH CERTIFICATES OF DEPOSIT

         As of December 31, 1997, Bancshares' interest-bearing liabilities in
excess of $100,000 which were estimated to mature or reprice within one year
were $26.9 million. If those interest-bearing liabilities (primarily
certificates of deposit) are not replaced as they mature, Bancshares' operations
and liquidity could be negatively affected. Bancshares currently has a high rate
of renewal of its certificates of deposit and expects that rate to continue. If
Bancshares were to suffer a decrease in the renewal of interest-bearing
liabilities, Bancshares would seek to manage its liquidity and operational
problems by raising Liberty's interest rates to attract new certificates of
deposit, having Liberty sell Small Business Administration loans, or having
Liberty borrow money from the Federal Home Loan Bank, of which it is a member.
There is, however, no assurance that these strategies would enable Bancshares to
restore satisfactory liquidity. 

YEAR 2000

         The computer systems of Sac River and Liberty, both internal and       
outsourced processing, could be affected by the "Year 2000" issue. The Year
2000 problem is the result of computer programs being written using two digits
rather than four to define the applicable year. Similar problems may arise with 
microprocessors and other embedded technology, such as lighting and cooling
system controls. Computers are a fundamental part of commercial banking in
terms of information storage and retrieval, check clearings, deposit postings,
loan payment processing, interest receivable and payable calculations, customer
notice generation, documentation preparation, and other areas. Embedded
technology is also widely used in mechanical systems and controls on bank
premises. Any embedded technology or programs used by Sac River or Liberty or
any of their vendors that have time-sensitive software may recognize the date
using "00" as the year 1900 rather than the year 2000, resulting in major
system failures or miscalculations. Similar problems could arise from failure
of software used by other banks and governmental financial institutions with
whom Liberty and Sac  




                                      13


<PAGE>   24
River maintain electronic ties, including electronic fund transfers. In
addition, if significant customers of either Sac River or Liberty are not Year
2000 compliant, they could suffer significant losses that might adversely affect
their ability to repay loans, borrow additional funds, or otherwise purchase Sac
River or Liberty services. Failures of Sac River, Liberty or third party
computer systems or embedded technology could, therefore, have a material effect
on the ability of Sac River and Liberty to conduct business, and could adversely
affect the results of their operations. Both Liberty and Sac River have
developed and are implementing plans to access their Year 2000 compliance and
the compliance of their vendors and major customers. Both institutions are also
developing contingency plans to deal with Year 2000 issues that may arise if
they or third parties are not fully compliant. The federal and state agencies
that regulate the two banks closely monitor Year 2000 compliance and could
impose penalties and sanctions if the institutions do not meet the compliance
standards established by the regulators. For a more detailed discussion of
Liberty's and Sac River's plans and Year 2000 readiness, see "Management's
Discussion and Analysis of Consolidated Financial Condition and Results of
Operations of Liberty Bancshares - Year 2000" and "Management's Discussion and
Analysis of Consolidated Financial Condition and Results of Operations of Sac
River - Year 2000." 

RISK ASSOCIATED WITH MERGER

         Certain forward-looking statements contained in this Proxy
Statement-Prospectus include the expected benefits from the proposed
transactions (see "Recommendation of the Sac River Board;" "Sac River's Reasons
for the Merger" and "Recommendation of the Liberty Board"; "Liberty's Reasons
for the Merger"), pro forma financial data, and similar information. Such
forward-looking statements use Sac River's and Liberty's internal estimates of
growth and results of operations and generally make no provisions for any
possible negative effects of the Merger. To the extent that events differ from
the assumptions, Bancshares' actual results of operations may vary materially
from the forward-looking statements. These forward-looking statements assume
that the deposit base of both Sac River and Liberty will remain substantially
intact pending the Merger and will grow at historical rates following the
Merger. To the extent that the Merger or other factors result in either a
temporary or long-term loss of deposits for Liberty, Bancshares' actual results
of operations may vary materially from the results anticipated by the
forward-looking statements.


COMPETITION

         Sac River and Liberty both face significant competition in their
respective markets. Increasing consolidation within the banking and financial
services industry, as well as increased competition from larger regional and
national out-of-state banking organizations and nonbank providers of various
financial services, may adversely affect the combined Bancshares' and Liberty's
ability to achieve the financial goals. Many of these large competitors have
significantly more financial resources, larger market share, and greater name
recognition in the market area to be served by the combined company.

LAWS AND REGULATIONS

         The businesses of Bancshares, Sac River and Liberty are subject to
extensive federal and state supervision and regulation. Changes in (i) laws and
regulations, including federal and state banking laws and regulations, with
which Bancshares and its subsidiaries must comply, and the associated costs of
compliance with such laws and regulations, (ii) accounting policies and
practices, as may be adopted by the relevant regulatory agencies as well as by
the Financial Accounting Standards Board, or (iii) Bancshares' and Liberty's
organization, compensation, and benefit plans, could cause actual results to
vary from the forward-looking statements in this Proxy Statement-Prospectus. See
"Business of Bancshares - Regulation and Supervision" and "Business of Sac River
- - Regulation and Supervision."

DEPENDENCE UPON KEY PERSONNEL

         Bancshares' and Liberty's future success will depend upon the continued
services of its senior management as well as its ability to attract additional
members to its management team with experience in the financial services
industry. The unexpected loss of the services of any of Bancshares' or Liberty's
key management personnel, or its inability to attract new management personnel
when necessary, could have a material adverse effect upon Bancshares and
Liberty. Bancshares maintains a $3 million key person insurance policy on Gary
Metzger. No other key management personnel are covered by similar insurance
policies. Other than Mr. Garry L. Robinson, Sac River's President, no officer or
director of Sac River, Liberty, or Bancshares is employed under an employment
agreement. Liberty will assume Sac River's obligations under Mr. Robinson's
employment agreement when the Merger is effective. See "Business of Bancshares
Regulation and Supervision" and "Business of Sac River - Regulation and
Supervision."

Stockton, Missouri on November 10, 1998, at 9:00 a.m., local time. Sac River

         Sac River has called the Special Meeting for the purpose of considering
and voting upon the Merger Agreement and the transaction of any and all other
business that may properly come before the Special Meeting or any adjournments
or postponements thereof.

         THE BOARD OF DIRECTORS OF SAC RIVER HAS APPROVED THE MERGER AND THE
MERGER AGREEMENT AND RECOMMENDS A VOTE FOR THE ADOPTION OF THE MERGER
AGREEMENT.

RECORD DATE

         Only holders of record of Sac River Common Stock at the close of
business on September 25, 1998 (the "Record Date"), are entitled to notice of,
and to vote at, the Special Meeting, or any adjournments or postponements of the
Special Meeting. 

VOTES REQUIRED

         As of the Record Date, there were 10,000 issued and outstanding shares
of Sac River Common Stock entitled to vote at the Special Meeting, held by
approximately 100 shareholders. Each holder of record of shares of Sac River
Common Stock at the close of business on the Record Date is entitled to cast,
for each share registered in his or her name, one vote on the Merger Agreement
and on each other matter presented to a vote of the shareholders at the Special
Meeting.

         The affirmative vote of the holders of two-thirds of the issued and
outstanding Sac River Common Stock, whether or not present or represented at the
Special Meeting, is required to approve the Merger Agreement. As of the Record
Date, directors and executive officers of Sac River owned 12.75% of the
outstanding shares of Sac River Common Stock. Members of the families of the
directors and executive officers of Sac River owned an additional 12.02% of the
outstanding shares of Sac River Common Stock. Sac River expects that all of its
officers and directors and their families will vote their shares in favor of
this Merger Agreement.

         Abstentions and "broker non-votes" will not be counted as votes for
approval of the Merger Agreement and, therefore, will have the effect of votes
against approval. A "broker non-vote" is a proxy from a broker or other nominee
of a Sac River shareholders indicating that such person has not received
instructions from the beneficial owner or other person entitled to vote the
shares that are represented by the proxy on a matter for which the broker or
other nominee does not have discretionary voting power.

         Bancshares, as the sole shareholder of Liberty, has voted in favor of
the Merger. Approval of the Merger Agreement by the stockholders of Bancshares
is not required under Missouri or other applicable law.

VOTING AND REVOCATION OF PROXIES

         The appointed proxy for Sac River will vote all shares of Sac River
Common Stock represented by a proxy properly signed and received at or prior to
the Special Meeting, unless subsequently revoked, in accordance with the
instructions on the proxy. If a proxy is signed and returned without any voting
instructions, shares of Sac River Common Stock represented by the proxy will be
voted FOR the proposal to approve the Merger. A shareholder may revoke any proxy
given pursuant to this solicitation by delivering to the Secretary of Sac River,
before or at the Special Meeting, a written notice revoking the proxy or a duly
executed proxy relating to the same shares bearing a later date or by voting in
person at the Special Meeting. Address all written notices involving a proxy to:
Sac River Valley Bank, P. O. Box B, Stockton, Missouri 65785, Attention: Garry
L. Robinson. Attendance at the Special Meeting will not, in and of itself,
revoke a proxy.

         The Board of Directors of Sac River is not aware of any business to be
acted upon at the Special Meeting other than as described herein. If, however,
other matters are properly brought before the

                                       16

<PAGE>   27
Special Meeting, or any adjournments or postponements thereof, the persons
appointed as proxies will have discretion to vote or act on such matters
according to their best judgment.

         Sac River's management may determine at the time of the Special Meeting
that it is in the best interest of Sac River and its shareholders to adjourn the
Special Meeting for up to 90 days if, among other reasons, at the time of the
special meeting, the holders of a sufficient number of shares of Sac River
Common Stock have indicated on their Election Notice that they intend to elect
under the Merger Agreement to receive cash rather the right to receive shares of
Bancshares Common Stock and, as a result, the total cash payable by Bancshares
to all shareholders of Sac River would exceed $7,657,000 (including a maximum of
$2,800,000 for the aggregate Optional Per Share Cash Amount and cash paid in
lieu of fractional shares). It is a condition to the closing of the Merger that
no more than $7,657,000 of the Merger consideration is cash. During the
adjournment representatives of Sac River would determine whether a sufficient
number of Sac River shareholders would reduce their cash election so that the
$7,657,000 condition could be satisfied. See "THE MERGER - Terms of the Merger"
for additional information about the Election Notice. 

         Sac River's Management may also determine that it is in the best
interest of Sac River and its shareholders to adjourn the Special Meeting for
other reasons. The person or persons appointed as proxies will have discretion
to act or vote on such proposed adjournment according to their best judgment.

SOLICITATION OF PROXIES

         Sac River will bear all expenses of solicitation of Sac River
shareholders in connection with the Special Meeting. In addition to solicitation
by use of the mails, directors, officers and employees of Sac River may solicit
proxies in person or by telephone, telecopy or by other means of communication.
Sac River will not pay these directors, officers and employees any compensation
for the solicitation, other than the compensation which they otherwise receive
in their capacity as directors, officers and employees, but Sac River may
reimburse them for out-of-pocket expenses in connection with the solicitation.


                                   THE MERGER

         This section describes all material provisions of the Merger Agreement,
as well as certain other aspects of the Merger. It is qualified by reference to
the Merger Agreement, included as Appendix A to this Proxy Statement-Prospectus,
which is incorporated herein by reference. Sac River shareholders should read
the Merger Agreement in its entirety.


BACKGROUND Of THE MERGER

         Beginning in late 1996, Gary E. Metzger, President of Bancshares, and
Garry L. Robinson, President of Sac River, began occasional discussions of a
possible merger of Sac River and Liberty. Sac River and Liberty have had
depository, loan participation and other relationships since Liberty opened in
1995, and Mr. Robinson and Mr. Metzger had worked together at other banks in the
1980's. During the period of the discussions between Mr. Robinson and Mr.
Metzger, the directors of both Sac River and Bancshares were considering a
variety of alternatives to expand their market bases, including internal
expansion and merger possibilities.


                                       17

<PAGE>   28
         Sac River's Board of Directors believed that opportunities for
significant growth in the Stockton market areas were limited and therefore
evaluated other markets. The directors believed that the Springfield area
offered the greatest possibilities for growth, whether through new branches,
acquisitions, or a merger.

         In the fall of 1997, Bancshares' Board of Directors adopted a strategic
plan to expand Bancshares through the addition of new locations. At that time,
Bancshares began looking for potential merger candidates, and its Board
authorized Mr. Metzger to begin discussions with potential candidates.

         Bancshares was interested in merging with a bank that had a similar
business philosophy, diverse ownership, was small to medium sized, had available
capital and was in a market complimentary to, but not significantly overlapping
with, Bancshares existing market. Mr. Metzger identified a number of potential
candidates, but determined that Sac River was the best candidate for merger
based on these factors and on the existing relationship between Sac River and
Liberty. Following the adoption of Bancshares' strategic plan, Mr. Metzger again
approached Mr. Robinson about a potential merger.

         On December 11, 1997, the Sac River Board unanimously agreed to explore
the possibility of a merger with Bancshares. In deciding to pursue a merger, the
Sac River Board of Directors considered a number of factors, including the
opportunities for expansion presented by a merger, particularly given Liberty's
existing locations, the need for Sac River to obtain updated technology, which
Liberty had, the creation of a greater market for the shareholders of Sac River
should they wish to sell their Sac River shares, provision for succession of
management, the ability for most Sac River shareholders to realize capital gains
treatment upon the disposition of their Sac River shares, and the retention of
Sac River management and board members by the surviving entity.

         On January 11, 1998, Gary Metzger met with the members of the Sac River
Board of Directors and management, including Garry Robinson, Stephen Wrenn,
Neale Johnson and Mike Neale to further discuss the Merger. Based upon those
discussions, Bancshares presented an oral merger proposal to the Sac River Board
on March 5, 1998. The proposal outlined the reasons for merger as previously
considered by the Sac River Board and outlined the basic pricing structure of
the merger, with the stock of Sac River being valued at 1.5 times book value and
Bancshares Common Stock being valued at 2 times book value of Liberty less
Bancshares' debt. Bancshares made its valuation based on the valuation of
similar transactions in the area and its knowledge of the financial position and
growth potential of both Sac River and Liberty, including Liberty's rapid growth
in the Springfield market and the absence of further significant growth
opportunities in Sac River's market area.

         The Sac River Board reviewed the merger proposal on March 5, 1998, and
agreed to pursue the merger, with modifications to the price structure initially
proposed by Bancshares. Sac River recommended that Sac River stock be valued at
1.5 times book value and Bancshares stock be valued at 1.8 times book value of
Liberty less Bancshares' debt.

         On March 17, 1998, the Bancshares and Liberty Boards of Directors
approved the terms of the Merger with a valuation of Bancshares stock at 1.85
times book value of Liberty less Bancshares' debt. On April 9, 1998, the Board
of Sac River approved the execution of a letter of intent, outlining the terms
of the Merger Agreement and the Boards of Bancshares and Liberty approved
execution of the letter of intent on April 21, 1998. On June 11, 1998, the Sac
River Board voted unanimously to approve the

                                       18

<PAGE>   29
Merger Agreement and to recommend that the shareholders of Sac River approve the
Merger. On June 16, 1998, the Boards of Bancshares and Liberty approved the
Merger Agreement.

REASONS OF THE BOARD OF DIRECTORS OF SAC RIVER FOR APPROVING THE MERGER

         In its deliberations concerning the Merger, the Board of Directors of
Sac River considered among other factors:

         -        similarities of the companies' management and operational
                  styles and philosophies,

         -        the reputations of the banks in their communities,

         -        the proposed members of the boards of directors, which would 
                  include all Sac River directors,

         -        the identity and experience of post-Merger management,

         -        possible uses of the combined banks' capital,

         -        the technology needs and resources of both banks,

         -        the relative size and competitive position of each bank, and 
                  the location of Liberty's branches,

         -        the price to be received by the Sac River shareholders and the
                  relative valuations of the Sac River Common Stock and 
                  Bancshares' Common Stock,

         -        the $986 per share appraised value for a minority holding by 
                  the ESOP, at December 31, 1997,

         -        the outlook for each bank in its current market environment,

         -        consolidation trends in the banking industry,

         -        the competitive position of the combined banks and the 
                  possibilities for internal growth and growth through 
                  acquisitions,
         -        the social and economic effects of the Merger on the banks' 
                  customers, employees and communities,

         -        the amount and source of earnings of each bank,

         -        the expected pro-forma earnings of the combined banks,

         -        the financial condition and risk profile of each bank,

         -        each bank's relative contribution to the combined entity's 
                  assets, liabilities and income,

                                       19
<PAGE>   30
         -        the tax free nature of the exchange of Sac River Common Stock 
                  for Bancshares Common Stock,

         -        the capital gains treatment of the cash consideration in the 
                  Merger for most Sac River shareholders,

         -        cost savings and economics of scale that the Board of
                  Directors believes may be realized by the Merger, although
                  such savings have not been quantified,

         -        the capitalization of the resulting entity and compliance with
                  regulatory capital requirements,

         -        terms of comparable transactions,

         -        the likelihood that the Merger will be approved by the 
                  regulatory authorities without undue conditions or delay,

         -        the terms and conditions of the Merger Agreement,

         -        the financial statements and quarterly call reports of both 
                  banks, and

         -        the potential impact of legislative and regulatory changes on 
                  banks.


RECOMMENDATION OF THE BOARD OF DIRECTORS OF SAC RIVER

         The Board of Directors of Sac River has determined that the Merger is
in the best interests of Sac River and its shareholders. THE BOARD OF DIRECTORS
UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF SAC RIVER VOTE IN FAVOR OF THE
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.

REASONS OF THE BOARDS OF DIRECTORS OF BANCSHARES AND LIBERTY FOR APPROVING THE 
MERGER

         The directors of Liberty and Bancshares unanimously approved the Merger
and the Merger Agreement at a joint meeting held on June 16, 1998.

         In approving the Merger and the Merger Agreement, the Boards of
Directors of Bancshares and Liberty took into account substantially the same
factors addressed by the Sac River Board of Directors. Of particular importance
to the Bancshares' directors were the capitalization of Sac River, the prior
relationships between the two banks, the purchase price, the economies of scale
that could be realized by nearly doubling Liberty's size, Bancshares' strategic
plan and Sac River's fit with that plan, Sac River's location, and consolidation
trends in the banking industry. Following consideration of these and other
factors, Bancshares' Board of Directors determined that the Merger would be in
the best interest of Liberty, Bancshares, and its shareholders.

                                       20

<PAGE>   31

         by delivering a new Election Notice to Sac River. Sac River will supply
         its shareholders additional copies of Election Notices upon receipt of
         their written request for them. Sac River shareholders who vote in
         favor of the Merger at the Special Meeting but do not submit an
         Election Notice will receive only Bancshares Stock if the Merger is
         approved. Shareholders who vote against the Merger or do not vote and,
         in either case do not submit an Election Notice, will receive only cash
         if the Merger is approved.
         The aggregate Mandatory Per Share Cash Amount will not exceed
$4,857,000, and the total cash payable by Bancshares as to the Optional Per

         The issued and outstanding shares of Sac River Common Stock held by a
shareholder who has validly exercised dissenters' rights under the Missouri
Revised Statutes ss. 362.730 (a copy of which is attached as Appendix C) will
not be converted into the right to receive cash or Bancshares Common Stock, as
described above, but instead a shareholder who validly exercises dissenter
rights will receive payment for his or her shares of Sac River Common Stock as
set forth in ss. 362.730. See "Dissenters' Rights of Sac River Shareholders."

EFFECTIVE TIME OF THE MERGER

         The Merger will become effective on a date (the "Effective Time") as
soon as the Merger Agreement is filed with the Division of Finance, which will
occur as soon as possible after the closing of the Merger. The closing of the
Merger will take place after the satisfaction of all of the conditions to the
Merger set forth in the Merger Agreement. There can be no assurance about
whether or when the Merger will occur. See "Condition to the Merger,"

         and (except to the extent such representations speak as of an earlier
         date) as of the closing date of the Merger Agreement as though made on

         have performed in all material respects each of the obligations it is
         required to perform under the Merger Agreement at or before the closing
         date under the Merger Agreement. Bancshares' chief executive officer
         must give Sac River a certificate to that effect.

                  (c) Consents Under Agreements. Each person whose consent or
         approval is required in connection with the transactions contemplated
         by the Merger Agreement under any loan or credit agreement, note,
         mortgage, indenture, lease or other agreement or instrument must have
         given Bancshares their consent or approval, except those consents and
         approvals that if not obtained would not, individually or in the
         aggregate, have a material adverse effect on Bancshares.

                  (d) No Material Adverse Change. Since the date of the Merger
         Agreement, no material adverse change in the business, operations,
         prospects or financial condition of Bancshares or Liberty may occur
         other than any such change attributable to or resulting from any change
         in law, regulation or generally accepted accounting principles that
         impairs both Sac River and Liberty in a substantially similar manner.
         At closing, Bancshares' chief executive officer must give Sac River a
         certificate to that effect.

                  (e) No Proceeding or Litigation. No material action, suit or
         proceeding before any court or any governmental or regulatory authority
         can be pending against Bancshares, Liberty, Sac River or any affiliate,
         associate, officer or director of any of them seeking to restrain,
         enjoin, 


                                       23

         prevent, change or rescind the transactions under the Merger
         Agreement or questioning their validity or legality.


                  (f) Allowance for Losses on Loans. If Sac River believes that
         Liberty's allowance for loan losses is inadequate, not later than ten
         (10) days before the closing of the Merger Sac River must recommend to
         the Board of Directors of Liberty an adjustment in the amount of the
         allowance. If the Liberty Board of Directors determines that the
         adjustment is reasonable and consistent with prudent banking practices,
         it must adopt the adjustment. If Liberty's Board of Director's does not
         adopt the adjustment, Sac River has the option to not consummate the
         Merger.

                  (g) Optional Cash Payment Limitation. The aggregate Optional
         Per Share Cash Amounts elected by the Sac River shareholders as of the
         closing date cannot exceed $2,800,000, less any amount paid for
         fractional shares.

                  (h) Tax Treatment. Sac River must reasonably believe, as of
         the Closing Date, that the Merger will qualify as one or more
         reorganizations under Code Section 368(a)(1).


         The obligation of Bancshares to consummate the Merger is also subject
         to:


                  (a) Representations and Warranties. Each of the
         representations and warranties of Sac River set forth in the Merger
         Agreement, without giving effect to any update, must be true and
         correct in all material respects as of the date of the Merger
         Agreement, and (except to the extent such representations and
         warranties speak as of an earlier date) as of the closing date of the
         Merger Agreement as though made on and as of the closing date. Sac
         River's chief executive officer must give Bancshares a certificate to
         that effect.

                  (b) Performance of Obligations of Sac River. Sac River shall
         have performed in all material respects each of the obligations it is
         required to perform under the Merger Agreement at or before the closing
         date under the Merger Agreement. Sac River's chief executive officer
         must give Bancshares a certificate to that effect.

                  (c) Consents Under Agreements. Each person whose consent or
         approval shall be required in order to permit the succession by Liberty
         pursuant to the Merger Agreement to any obligation, right or interest
         of Sac River under any loan or credit agreement, note, mortgage,
         indenture, lease or other agreement or instrument must have given Sac
         River their consent or approval, except those for consents and
         approvals that if not obtained would not, individually or in the
         aggregate, have a material adverse effect on Sac River or Liberty.

                  (d) No Material Adverse Change. Since the date of the Merger
         Agreement, there must have been no material adverse change in the
         business, operations, prospects or financial condition of Sac River
         other than any such change attributable to or resulting from any change
         in law, regulation or generally accepted accounting principles that
         impairs both Sac River and Liberty in a substantially similar manner.
         Sac River's chief executive officer must give Bancshares a certificate
         to that effect.


                                       24

<PAGE>   35


                  (e) No Proceeding or Litigation. No material action, suit or
         proceeding before any court or any governmental or regulatory authority
         can be pending against Bancshares, Liberty, Sac River or any affiliate,
         associate, officer or director of any of them seeking to restrain,
         enjoin, prevent, change or rescind the transactions under the Merger
         Agreement questioning their validity or legality.

                  (f) Allowance for Losses on Loans. If Bancshares believes that
         Sac River's allowance for loan losses is inadequate, not later than ten
         (10) days before the closing of the Merger, Bancshares will recommend
         to the Board of Directors of Sac River an adjustment in the amount of
         the allowance. If the Sac River Board of Directors determines that the
         adjustment is reasonable and consistent with prudent banking practices,
         it must adopt the adjustment. If Sac River's Board of Directors does
         not adopt the adjustment, Bancshares has the option to not consummate
         the Merger.

                  (g) Outstanding Common Stock. As of the Closing Date, no more
         than ten thousand (10,000) shares of Sac River Common Stock can be
         outstanding, and the Optional Per Share Cash Amount cannot exceed
         $2,800,000, less any amount paid for fractional shares.


         Sac River and Bancshares cannot provide assurances about when or
whether all of the conditions precedent to the Merger can or will be satisfied,
or waived by the party permitted to waive them.

CONDUCT OF BUSINESS PENDING THE MERGER

         Under the Merger Agreement, Sac River must conduct its business in the
usual and ordinary course consistent with its past practice until the Merger is
concluded. Sac River has agreed to use its best efforts to preserve its business
organization and assets and maintain its rights and to use its reasonable best
efforts to retain the services of its officers and key employees.

WAIVER AND AMENDMENT

         The parties to the Merger Agreement may amend it by action taken or
authorized by their respective Boards of Directors at any time before approval
of the Merger by the shareholders of Sac River and Liberty. After those
approvals the parties cannot adopt an amendment that changes the consideration
the shareholders will receive in the Merger in a way that is adverse to the
shareholders interests. Any amendment must be in writing and signed by each of
the parties.

         If authorized by their respective Boards of Directors, and to the
extent legally allowed, before the Effective Time, Sac River or Bancshares may:
(i) extend the time for the performance of any of the obligations or other acts
of the other party under the Merger Agreement, (ii) waive any inaccuracies in
the representations and warranties of the other contained in the Merger
Agreement or in any document delivered by the other pursuant to the Merger
Agreement, and (iii) waive compliance by the other with any of the agreements or
conditions contained in the Merger Agreement. Any agreement on the part of a
party to any extension or waiver is valid only if set forth in a written
instrument signed on behalf of that party.

         Sac River represents in the Merger Agreement, among other things, that
it is duly organized and in good standing, that it has the authority to enter
into the Merger Agreement, that its capital stock is 


                                       25

<PAGE>   36

accurately described in the Merger Agreement, that it has provided Bancshares
with accurate financial statements, that it has all necessary authorizations to
conduct its business, that it has paid all of its taxes and that it is not
involved in any litigation. Bancshares and Liberty make similar representations.
These representations and warranties do not survive following the Effective Time
of the Merger. If any of the representations and warranties are not true, the
other party is not entitled to indemnification from the party making the
representation and warranty for any loss suffered as a result.

TERMINATION

         The Merger Agreement and the Merger may be terminated at any time
before the Effective Time, both before or after the Sac River shareholders have
approved the Merger Agreement:

                  (a) by mutual consent of the Boards of Directors of Bancshares
         and of Sac River;

                  (b) by Bancshares or Sac River (i) if there has been a
         material breach of any representation, warranty, covenant or agreement
         contained in the Merger Agreement by Sac River, on the one hand, or
         Bancshares, on the other hand, or (ii) if the representations and
         warranties of Sac River, on the one hand, or Bancshares, on the other
         hand, are or have become materially untrue in the aggregate, and in
         either case the breach or other condition has not been cured within
         thirty (30) business days following receipt of the non-terminating
         party of notice of the breach or other condition;

                  (c) by Bancshares, on the one hand, or Sac River, on the other
         hand, if any permanent injunction preventing the consummation of the
         Merger has become final and nonappealable;

                  (d) subject to the Merger Agreement, by the Board of Directors
         of Bancshares or the Board of Directors of Sac River if the Merger
         shall not have been consummated before March 31, 1999, for a reason
         other than the failure of the terminating party to comply with its
         obligations under the Merger Agreement;

                  (e) by the Board of Directors of Bancshares or the Board of
         Directors of Sac River if (i) the Federal Reserve Board, the Division
         of Finance, the FDIC or other applicable bank regulatory authority has
         denied approval of the Merger and neither Bancshares nor Sac River has,
         within thirty days after the entry of the order denying approval, filed
         a petition seeking review of such order as provided by applicable law
         or (ii) if the parties petition for review, relief is denied; and

                  (f) by Sac River or Bancshares, if the shareholders of Sac
         River and Liberty do not approve the Merger Agreement and the Merger
         after a vote at a meeting of Sac River's or Liberty's shareholders (or
         any adjournment thereof) called and held for the purpose of acting on
         the Merger Agreement.

EXPENSES

         Except for printing and regulatory filing fees, Bancshares and Sac
River are responsible for the payment of their respective expenses in connection
with the Merger. Bancshares will pay the total printing 


                                       26
<PAGE>   37

and regulatory filing fees required for the Merger. If Sac River has not paid
certain expenses by the time of the Merger, Liberty will pay them following the
Merger.

EFFECT ON EMPLOYEE BENEFIT PLANS


         Bancshares Incentive Stock Option Plan. In 1995, Bancshares established
an incentive stock option plan for key employees of Bancshares and Liberty (the
"ISO Plan"). Under the ISO Plan only employees of Liberty and Bancshares
selected by the Incentive Stock Option Committee of Bancshares are eligible to
receive options. Each option granted by the Incentive Stock Option Committee is
evidenced by a written agreement. The purchase price of the stock under each
option is the fair market value of the stock at the time of the grant of the
option. All outstanding option agreements provide that the option recipients
must exercise their options within ten (10) or fewer years after the options
were granted.


         Options granted under the ISO Plan are intended to be treated as
incentive stock options under I.R.C. Section 422. At the time of option grant or
exercise, the option holder incurs no income tax liability. Generally, when the
option holder sells the shares obtained upon exercise of the option, he or she
will be taxed at capital gains rates on the difference between the sale price
and the option exercise price. However, if the employee disposes of ISO stock
before the statutory holding period expires, it is considered a disqualifying
disposition. The effect of a disqualifying disposition on the employee is that
the employee must recognize as compensation income the gain on the disposition.
For this purpose, the gain is equal to the difference between the option
exercise price and the stock's fair market value at the time of option exercise.
The statutory holding period is the later of two years from the date of the
granting of the ISO to the employee or one year from the date that the shares
were transferred to the employee upon exercise.

         Bancshares, as the grantor of the option, does not recognize any
compensation expense upon the grant or exercise of incentive stock options or
upon the sale of any shares issued upon the exercise of the options. However,
upon a disqualifying disposition of ISO stock, the employer may deduct from
income in the year of the disqualifying disposition an amount equal to the
amount that the employee recognizes as compensation income due to the
disqualifying disposition.

         As of June 1, 1998, Bancshares has issued options to purchase 16,000
shares of Bancshares common stock under the ISO plan to five (5) employees. The
options have an average exercise price of $12.88 per share. As of June 1, 1998,
none of these options had been exercised.

         Bancshares intends to continue the ISO Plan after the Merger is
concluded and may, from time to time, issue additional options to employees of
Bancshares and Liberty, including former employees of Sac River who become
employees of Liberty or Bancshares.


         Sac River's Employee Stock Ownership Plan. Effective January 1, 1989,
Sac River established an employee stock ownership plan (the "ESOP"). The ESOP is
a qualified retirement plan within the meaning of I.R.C. Section 401. As of
December 31, 1997, the ESOP held 433 1/3 shares of Sac River Common Stock and
had 22 participants who were employees (or former employees) of Sac River.



                                       27
  

<PAGE>   38

        Sac River established the ESOP to provide retirement benefits to
eligible employees. The ESOP is designed to invest primarily in Sac River common
stock (commonly referred to as "employer securities"). The plan year for the
ESOP is the calendar year.

         The sole trustee of the ESOP is Garry Robinson, President and a
director of Sac River. As trustee, Mr. Robinson has certain fiduciary duties to
the participants of the ESOP, including a duty to discharge his duties solely in
the interests of the participants and their beneficiaries and for the exclusive
purpose of providing benefits to participants and their beneficiaries, with the
care, skill, prudence and diligence under the circumstances then prevailing that
a prudent person acting in a like capacity and familiar with such matters would
use.

         Sac River Common Stock held by the ESOP is allocated to the accounts of
the participants (commonly referred to as "employer securities accounts"). In
addition to employer securities accounts, participants also have general
investments accounts, to which are allocated all assets of the ESOP other than
Sac River Common Stock. A participant has the right to direct the trustee
regarding the voting of the Sac River Common Stock allocated to his or her
account with respect to the approval or disapproval of the Merger. The trustee
does not have the right to vote any Sac River Common Stock for which he receives
no direction.

         Although the ESOP does not provide that the ESOP participants may
direct the trustee as to the investment of their accounts, the trustee has
determined to allow ESOP participants to elect to receive cash or Bancshares
Common Stock for the shares of Sac River Common Stock allocated to their
accounts. Any cash received by the trustee for shares of Sac River Common Stock
allocated to the accounts of participants will be allocated to the general
investments accounts of those participants, and will be invested by the trustee
in a manner similar to the current investment of the general investment accounts
of the participants. As to any participants who fail to make an election, the
trustee has determined to elect to receive cash for the shares of Sac River
common stock allocated to their accounts. The trustee believes such investment
to be prudent and reasonable and to be in the best interests of the
participants.

         Following the Merger, Liberty will be considered the employer with
respect to the ESOP, and any shares of Bancshares Common Stock allocated to the
accounts of the participants will be considered "employer securities" under the
ESOP. Under the ESOP, the employer issues a "put option" to each participant
receiving a distribution of employer securities from the ESOP. The put option
permits the participant to sell the employer securities to the employer, at any
time during two (2) option periods, at the current fair market value of the
employer securities. The first put option period runs for a period of at least
sixty days commencing on the date of distribution of employer securities to the
participant. The second put option period runs for a period of at least sixty
days commencing after a new determination of the fair market value of the
employer securities and notice to the participants of the new fair market value.
If a participant exercises his or her put option, the employer must purchase the
employer securities at fair market value upon the terms as set forth in the
ESOP. If a participant of the ESOP elects to exercise his or her put option,
Bancshares will purchase the employer securities held by the participant at fair
market value as provided in the ESOP. "Fair market value", for purposes of the
ESOP, means the value of the employer securities determined as of the last day
of the preceding plan year (except for certain individuals, such as officers,
directors, or highly compensated employees of the employer, in which case, fair
market value shall be determined as of the date of the exercise of the put
option).


                                       28


<PAGE>   39

         Following the merger, the trustee must value the assets of the ESOP as
of the last day of each plan year to determine the fair market value of each
participant's accrued benefit in the ESOP. An independent appraiser must perform
all valuations of employer securities which are not readily tradeable on an
established securities market.

         Liberty's and Sac River's 401(k) Plans. Each of Liberty and Sac River
maintains a defined contribution plan that is qualified under IRC Section
401(k). Section  401(k) plans allow participants who have met certain
eligibility requirements to defer a percentage of their compensation each year
(up to a maximum dollar amount allowed by law--$10,000 for 1998) instead of
receiving such amount in cash. The amount elected to be deferred, and any
earnings on that amount, will not be subject to income tax until it is actually
distributed to the participant.

         Sac River's Section 401(k) Plan. Sac River's Section 401(k) Plan was
originally adopted as of January 1, 1988, and was subsequently amended as of
January 1, 1996. The plan specifications are as follows:

                  1. Plan Contributions. Plan contributions to a participant's
         account may consist of one or more of the following: (a) Employee
         salary deferrals (maximum of $10,000 in 1998); (b) Employer
         discretionary matching contributions equal to an employee's salary
         deferrals up to a maximum of six percent (6%) of compensation (employee
         need not be employed on last day of plan year to receive this
         contribution); (c) Employer qualified non-elective contributions on
         behalf of non-highly compensated employees (employee must be employed
         on last day to receive contribution); and (d) Employer discretionary
         non-elective contributions (employee must be employed on last day of
         plan year to receive contribution.)

                  Any employer contributions will be allocated based on the
         participant's pro rata share of compensation in relation to all
         participants' total compensation.

                  2. Eligibility Requirements. An employee is eligible to
         participate in the Section 401(k) plan upon completion of six (6)
         months of service and has attained the age of 20 1/2. If the employee
         is in the employ of the employer six (6) months after his/her
         employment commencement date, then the employee will have completed six
         (6) months of service.

                  3. Effective Date of Participation. An employee will become a
         participant of the Section 401(k) plan on the first day of the plan
         year following the date the employee satisfies the eligibility
         requirements.

                  4. Vesting Schedule. An employee's "vested percentage" in his
         Section 401(k) account shall be determined on a seven (7) year graded
         vesting schedule (20% after second year of service and 100% after seven
         years of service); provided, however, the employee shall always be 100%
         vested in any salary reduction amounts, direct roll overs from another
         qualified plan and any special qualified non-elective contributions by
         the employer. A six (6) year graded vested schedule (20% after first
         year of service and 100% after six years of service) shall be used for
         "top-heavy" plans.

                  For vesting purposes, an employee will have completed a year
         of service if credited with 1,000 hours of service during the plan
         year.

                                       29


<PAGE>   40

                  5. Participant Loans. An employee is eligible to receive a
         loan from his or her Section 401(k) plan subject to the lesser of (i)
         $50,000 or (ii) one-half of his or her account balance (but in no event
         shall a loan be made for less than $1,000); provided, such loan is
         adequately secured, bears a reasonable interest rate and is paid over a
         reasonable period of time, not to exceed five (5) years.

                  6. Retirement Benefits. Upon reaching the age of 65, an
         employee shall be 100% vested in his or her Section 401(k) account;
         provided, however, an employee shall be eligible for an early
         retirement at age 55 if such employee has completed 10 years of
         service.

         Liberty's Section 401(k) Plan. Liberty's Section 401(k) plan was
adopted on January 1, 1998, and the plan specifications are as follows:

                  1. Plan Contributions. Plan contributions to a participant's
         account may consist of one or more of the following: (a) Employee
         salary reductions subject to a maximum of 15% of compensation but not
         to exceed the amount allowed by law (maximum of $10,000 in 1998); (b)
         Employer discretionary matching contributions based upon the employee's
         salary deferrals; (c) Employer discretionary qualified non-elective
         contributions on behalf of non-highly compensated employees; and (d)
         Employer discretionary non-elective contributions.

                  Employer discretionary contributions shall be based on an
         employee's pro rata share of compensation as it relates to the total
         compensation paid to all employees.

                  2. Plan Year. The plan year begins on January 1 and ends on
         December 31 of each year.

                  3. Eligibility Requirements. An employee shall be eligible to
         participate in the Section 401(k) plan upon completion of one year of
         service and has attained the age of eighteen (18). An employee shall be
         credited with one year of service upon completion of 1,000 hours of
         service.

                  4. Effective Date of Participation. The plan provides for
         semi-annual entry dates (January 1 or July 1) whereby the employee
         shall commence participation in the plan on the earlier of such date
         after the employee satisfies the eligibility requirements.

                  5. Vesting Schedule. An employee's "vested percentage" in his
         or her Section 401(k) account shall be 100% after six years of service
         for any non-qualified employer contributions; provided, however, the
         employee shall have a 100% nonforfeitable interest at all times in any
         salary deferral contributions, any employer qualified non-elective
         contributions, and any qualified matching contributions. For
         "top-heavy" plans, a six (6) year graded vesting schedule shall apply
         (20% after the first year of service and 100% after five years of
         service).

                  6. Participant Loans. Employee loans are not allowed.

                  7. Retirement Benefits. Upon attaining the age of 65, an
         employee shall be 100% vested in his or her Section 401(k) account.


                                       30

         As soon as administratively practicable following the merger, Sac
River's Section 401(k) plan shall be terminated or merged with Liberty's 401(k)
plan at the discretion of Liberty's Board of Directors.

BANK REGULATORY MATTERS

         Under the Merger Agreement, it is a condition to each party's
obligation to effect the Merger that all regulatory approvals, authorizations,
and consents required to consummate the Merger (collectively the "Requisite
Regulatory Approvals") have been obtained and are in full force and effect and
all waiting periods associated with them have expired. Bancshares and Sac River
have agreed to use all reasonable efforts to obtain the approvals discussed
below. There can be no assurance that any or all regulatory approvals will be
obtained, and, if obtained, there can be no assurance about the date of any of
them. It is also possible that some or all of the Requisite Regulatory Approvals
will impose a condition or restriction that would materially adversely affect
the benefits of the Merger to Bancshares or Sac River or their shareholders and
render the consummation of the Merger inadvisable. It is also possible that a
third party could challenge the approvals through litigation.

         Bancshares must submit an application (the "FDIC Application") to the
FDIC pursuant to Section 18(c) of the Federal Deposit Insurance Act (the "FDIA")
seeking the prior approval of the FDIC to the Merger of Sac River with and into
Liberty. Under applicable law, the FDIC may not approve any transaction under
Section 18(c) of the FDIA: (i) that would result in a monopoly or which would be
in furtherance of any combination or conspiracy to monopolize or to attempt to
monopolize the business of banking in any part of the United States; or (ii) the
effect of which in any section of the United States may be substantially to
lessen competition, or to tend to create a monopoly, or result in a restraint of
trade, unless the FDIC finds that the anti-competitive effects of the
transaction are clearly outweighed in the public interest of the probable effect
of the transaction in meeting the convenience and needs of the communities to be
served.

         In addition, the FDIC must also take into consideration the financial
and managerial resources and future prospects of Sac River and Liberty, and the
convenience and needs of the communities to be served. A merger subject to
Section 18(c) of the FDIA may not be consummated before thirty days following
approval by the FDIC or any shorter period that the FDIC permits, during the
waiting period the Attorney General of the United States may object to the
merger on antitrust grounds.

         Bancshares and Sac River must also submit applications (the "Division
of Finance Applications") to the Division of Finance. The Division of Finance
has full power to approve or disapprove the Merger. The Division of Finance
looks at substantially the same considerations as the FDIC in determining
whether to approve the Merger.

         Bancshares must also submit an application (the "FRB Application") to
the Federal Reserve Board pursuant to Sections 3(a)(3) of the Bank Holding
Company Act of 1956, as amended (the "BHCA") seeking the prior approval of the
Federal Reserve Board to consummate the Merger. Assuming the Federal Reserve
Board approves the FRB Application, the Merger may not be consummated for up to
30 days after such approval, during which time the United States Department of
Justice may challenge the Merger on antitrust grounds.
     
         The FRS Board is prohibited from approving any acquisition or merger
pursuant to Section 3 of the BHCA: (i) that would result in a monopoly or that
would be in furtherance of any combination or 


                                       31

<PAGE>   42

conspiracy to monopolize or to attempt to monopolize the business of banking in
any part of the United States; or (ii) the effect of which in any section of the
United States may be substantially to lessen competition, or to tend to create a
monopoly, or result in a restraint of trade, unless the Federal Reserve Board
finds that the anti-competitive effects of the transaction are clearly
outweighed in the public interest by the probable effect of the transaction in
meeting the convenience and needs of the communities to be served.

         In reviewing the FRB Application, the FRS Board also considers the
financial condition and future prospects of Bancshares, Liberty and Sac River,
the convenience and needs of the community to be served, and the competency,
experience and integrity of their respective officers and directors. In
addition, the FRS Board will disapprove an application if the applicant has
failed to provide the FRS Board with adequate assurances it will make available
information about its operations and activities as the Board determined to be
appropriate.

SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         The following discussion is a summary that contains a description of
the material United States Federal Income Tax considerations for Bancshares,
Liberty, Sac River, and Sac River shareholders with respect to the Merger, based
upon the opinion of Husch & Eppenberger, LLC, counsel for Bancshares and Liberty
about the material federal income tax matters with respect to the Merger. That
opinion is based on certain representations, warranties, and assumptions made by
the management of Bancshares, Liberty and Sac River, on which the management of
Bancshares, Liberty and Sac River expressly authorized Husch & Eppenberger, LLC
to rely in preparing its tax opinion. The opinion is also based on the Internal
Revenue Code of 1986, as amended (the "Code"), regulations, rulings and
decisions in effect on the date of this Proxy Statement-Prospectus, all of which
are subject to change. This summary does not discuss any aspect of state, local,
or foreign taxation and does not discuss all the tax considerations that may be
relevant to Sac River shareholders in light of their particular circumstances,
or to certain types of shareholders that may be subject to special tax rules,
such as financial institutions, tax exempt organizations, insurance companies,
dealers in stock or securities, foreign corporations, and individuals who are
not citizens or residents of the United States. The discussion with respect to
Sac River shareholders is limited to those shareholders who have held Sac River
Common Stock and who will hold the Bancshares Common Stock received in the
Merger as "capital assets" within the meaning of Section 1221 of the Code.

         SAC RIVER SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS IN
DETERMINING THE TAX CONSIDERATIONS THAT MAY BE RELEVANT IN CONNECTION WITH THE
PROPOSED MERGER, INCLUDING THE APPLICATION TO THEIR PARTICULAR SITUATION OF THE
TAX CONSIDERATIONS DISCUSSED BELOW, AS WELL AS THE APPLICATION OF STATE, LOCAL,
FOREIGN, OR OTHER TAX LAWS.

         Accordingly, in the opinion of Husch & Eppenberger, LLC the material
federal income tax 


                                       32

<PAGE>   43


consequences of the Merger will be:

         1. The Merger will constitute a "reorganization" within the meaning of
         Code Section 368(a)(1)(A) and Code Section 368(a)(2)(D), and each of
         Bancshares, Liberty and Sac River will be a party to a reorganization
         within the meaning of Code Section 368(b).

         2. No gain or loss will be recognized by Bancshares, Liberty, or Sac
         River as a result of the Merger.

         3. Sac River shareholders will not recognize any gain or loss upon the
         receipt of Bancshares Common Stock (as opposed to cash) in exchange for
         their Sac River Common Stock.

         4. The tax basis of the Bancshares Common Stock received by a Sac River
         shareholder will be the same as the basis of the Sac River Common Stock
         surrendered in exchange therefor reduced by the portion of the basis
         allocable to the fractional share of Bancshares stock received in the
         Merger.

         5. The holding period for Bancshares stock received by a Sac River
         shareholder in the Merger will include the period during which the Sac
         River Common Stock surrendered in exchange therefor was held.

         6. Each Sac River shareholder will recognize gain equal to the lesser
         of (i) the amount of cash received in the Merger or (ii) the amount, if
         any, by which the sum of the cash plus the fair market value of the
         Bancshares stock received in the Merger exceeds the stockholder's basis
         in the Sac River shares surrendered. For purposes of determining the
         character of such gain, the cash received in the Merger will be treated
         as if shares of Bancshares Common Stock equal in value to the cash had
         been distributed to the Sac River shareholder as part of the Merger and
         then immediately after the Merger such shares were redeemed by
         Bancshares. Depending upon the particular circumstances of each
         shareholder, such cash payments will be characterized as either having
         been received as a distribution in full payment in exchange for the
         Bancshares stock deemed to have been redeemed or as having been
         received as a dividend, as provided in Section 302 of the Code. A cash
         payment will be treated as a distribution in full payment in exchange
         for the Bancshares stock if the deemed redemption is "substantially
         disproportionate" within the meaning of Section 302(b)(2) of the Code,
         is in complete termination of the shareholder's interest in the
         corporation within the meaning of Section 302(b)(3) of the Code or is
         "not essentially equivalent to a dividend" within the meaning of
         Section 302(b)(1) of the Code. A redemption is treated as
         "substantially disproportionate" if: (1) the shareholder owns less than
         50% of the total combined voting power of all classes of stock
         immediately after the redemption; (2) the ratio of the shareholder's
         holdings of voting stock immediately after the redemption to all the
         voting stock in the corporation at that time is less than 80% of the
         ratio which the voting stock the shareholder 


                                       33
<PAGE>   44

         owned immediately before the redemption bore to the entire voting stock
         in the corporation at that time (the "80% Test"); and (3) the
         shareholder's ownership of common stock (whether voting or nonvoting)
         after and before the redemption also meets the 80% test. A redemption
         is treated as "not essentially equivalent to a dividend" if it results
         in a meaningful reduction of the shareholder's proportionate interest
         in the corporation. When making a determination as to whether a
         redemption is substantially disproportionate or not essentially
         equivalent to a dividend, or, subject to certain exceptions, whether
         the redemption terminates the shareholder's entire interest in the
         corporation, the constructive ownership rules of Section 318 of the
         Code apply. If the cash payment is treated as having been received by a
         Sac River shareholder as a distribution in full payment in exchange for
         redeemed shares, such shareholder's gain recognized on the Merger will
         be short-term, mid-term or long-term capital gain, depending upon the
         Sac River shareholder's holding period for the Sac River stock. If the
         cash payment is treated as having been received by a Sac River
         shareholder as a dividend, the shareholder's gain on the Merger will be
         recognized as ordinary income. Sac River shareholders should consult
         their tax advisors on the tax treatment of the cash payments that they
         receive.

RESALES OF BANCSHARES COMMON STOCK ISSUED IN THE MERGER

         The shares of Bancshares Common Stock issued pursuant to the Merger
will be freely transferable under the Securities Act immediately following the
Merger, except for shares issued to any Sac River shareholder who may be deemed
to be an "affiliate" of Sac River or Bancshares for purposes of Rule 145 under
the Securities Act. This Proxy Statement/Prospectus does not cover resales of
shares of Bancshares Common Stock received in the Merger by any person who may
be deemed to be an affiliate of Sac River or Bancshares. At the time of the Sac
River Special Meeting (in the case of Sac River affiliates) or at the Effective
Time (in the case of Bancshares affiliates), persons who may be deemed to be
affiliates of Sac River or Bancshares generally include individuals who, or
entities which, control, are controlled by or are under common control with Sac
River or Bancshares and will include directors and certain executive officers of
Sac River and Bancshares and may include principal shareholders of Sac River or
Bancshares.

         Securities Act Rules 144 and 145 restrict the sale of Bancshares Common
Stock received in the Merger by Sac River affiliates and certain of their family
members and related interests.

         Generally, during the one year period following the Effective Time,
affiliates of Sac River who are not affiliates of Bancshares may publicly resell
Bancshares Common Stock received by them in the Merger, subject to certain
limitations on the number of shares they can sell in any three month period and
subject to the requirement that they sell the shares in broker transactions.
Bancshares is under no obligation to insure that any registered broker-dealer
will be available to conduct sales in accordance with Rule 144.

         Following the initial one year period, affiliates of Sac River who are
not affiliates of Bancshares and all other Sac River shareholders who received
Bancshares Common Stock in the Merger may resell their shares without these
restrictions so long as there is adequate current public information available
about Bancshares. Bancshares, however, is under no obligation to make such
information available and does not presently plan to do so. Accordingly, resales
under Rule 144 may not be possible, and the former Sac River shareholders should
consult their counsel about the availability of other exemptions under the
Securities Act before they attempt to sell their Bancshares stock.


                                       34
<PAGE>   45

         Sac River shareholders who become affiliates as a result of the Merger
will be subject to the same restrictions on resale that apply to Sac River
affiliates during the year following the Merger that are described above, but in
the case of these Bancshares' affiliates, the restrictions will continue until
they have ceased to be affiliates. These shareholders should also consult their
counsel about the availability of exemptions under the Securities Act before
they attempt to resell any of their Bancshares stock.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

RELATED STOCK OWNERSHIP

         Richard A. Pendleton, a director of Liberty and Bancshares, is
co-trustee of the Anise C. Brasher Revocable Trust U/T/A dated August 1, 1995,
which owns shares of Sac River Common Stock. No other directors, executive
officers or principal shareholders of Bancshares own shares of Sac River Common
Stock. No directors, executive officers or principal shareholders of Sac River
own shares of Bancshares Common Stock.

LOAN PARTiCIPATION

         Sac River has purchased participations in loans originated by Liberty.
The outstanding balance of these participations as of June 30, 1998 was
$8,199,700. Liberty has purchased participations in loans originated by Sac
River. The outstanding balance of these participations as of June 30, 1998 was
$1,650,600. These loan participations were made in the ordinary course of
business of Liberty and Sac River and were made on an "arm's length" basis. None
were past due or nonperforming, and neither Sac River or Liberty has had to
write off all or any portion of a loan participation it has purchased from the
other.

LEGAL COUNSEL

         The law firm of Husch & Eppenberger, LLC, has represented Bancshares
throughout the negotiation of the proposed acquisition. Members of Husch &
Eppenberger, LLC, have also represented Sac River in connection with the
establishment and administration of Sac River's ESOP. Sac River engaged the law
firm of Yates, Mauck, Bohrer, Ellif, Croessmann, Wieland, P.C. ("Yates, Mauck")
to assist Sac River in negotiating the terms of the Merger Agreement and to
provide legal advice with respect to the Merger. Yates, Mauck represented
Bancshares in the formation of Bancshares in 1995. Yates, Mauck ceased
representing Bancshares in 1996. Sac River and Bancshares have waived all actual
and potential conflicts of interest on the part of both firms.

         Sac River has made loans to the following directors or officers of
Bancshares, either personally or to businesses that are owned in whole or in

Hamilton, Howard Jackson Hoke, Dixie F. Letsch, Richard A. Pendleton, Wayne A.
Scheer and Charles Talbert Wooten, Jr. These loans were made in the ordinary
course of business of Sac River and were made on an "arm's length" basis on
terms equivalent to those extended to similar borrowers. The outstanding balance
of those loans at June 30, 1998, was $10,466,400. None of these loans are past
due or nonperforming. Liberty has not made any loans to officers or directors of
Sac River.

                         DISSENTERS' RIGHTS OF HOLDERS
                            OF SAC RIVER COMMON STOCK

         If Sac River Shareholders approve the Merger and the Merger occurs, any
shareholder of Sac River who properly dissents from the Merger at the Special
Meeting may be entitled to receive in cash the reasonable value of his or her
shares of Sac River Common Stock determined immediately prior to the Merger,
excluding any appreciation or depreciation in anticipation of the Merger.
FAILURE TO COMPLY STRICTLY WITH THE PROCEDURES PRESCRIBED BY APPLICABLE LAW WILL
RESULT IN THE LOSS OF DISSENTERS' RIGHTS.

         Pursuant to Missouri Revised Statutes Section 362.730, any shareholder
of Sac River who does not vote in favor of the agreement to merge at the
shareholders' meeting called for that purpose is entitled to receive from
Bancshares the reasonable value of such shareholder's shares of Sac River Common
Stock at the time of the Merger. The value of Sac River Common Stock will be
determined as follows:

                  (1) Within sixty (60) days after the Effective Time of the
         Merger, the dissenting shareholder may apply to the Circuit Court of
         Greene County, Missouri, by petition for the appointment of appraisers
         to value the dissenter's stock.

                  (2) At any time during the sixty (60) day period any other
         dissenting shareholder of Sac River may file his or her petition in the
         Circuit Court of Greene County for the determination of his or her
         shares of stock.

                  (3) Any shareholder who does not become a party to a
         proceeding in Greene County, within sixty (60) days from the Effective
         Time of the Merger shall be conclusively presumed to have assented to
         the Merger.

         After expiration of the sixty (60) days from the Effective Time of the
Merger, the Circuit Court of Greene County will appoint three appraisers to
determine the value of the dissenting shareholders' share of Sac River Common
Stock. A copy of Section 362.730 is attached as Appendix C.

                     DESCRIPTION OF BANCSHARES COMMON STOCK

         Bancshares is authorized to issue 5,000,000 shares of common stock, par
value $1 per share, of which 511,090 shares were issued and outstanding as of
June 30, 1998. Bancshares held no shares in its treasury on that date.
Bancshares has no other class of authorized or issued capital stock.

         Each share of Bancshares Common Stock has the same rights, privileges
and preferences as every other share of Bancshares Common Stock. Each
shareholder is entitled to one vote per share in any matter requiring a vote at
any meeting, including the election of directors, and is entitled to participate
in the liquidation, dissolution or winding up on the basis of such shareholder's
pro rata holdings of the Bancshares Common Stock. Shareholders do not have
cumulative voting rights in the election of directors, and, as of the Effective
Time of the Merger, Bancshares' shareholders will not have preemptive rights
when Bancshares issues shares of the Common Stock to other persons.

         Each Bancshares shareholder participates equally in dividends, which
are payable when and as declared by the board of directors of Bancshares out of
funds that are legally available for that purpose. Bancshares has never declared
or paid any cash dividends and has no present intention to do so after the
Merger.


                        COMPARISON OF SHAREHOLDER RIGHTS

         Bancshares is a corporation incorporated under Chapter 351 of the
Revised Missouri Statutes and, as a result, the rights of stockholders of
Bancshares are governed by Missouri law, the Articles of Incorporation of
Bancshares (the "Bancshares Articles") and the by-laws of Bancshares
(the"Bancshares By-laws"). Sac River is a state chartered banking corporation
formed under Chapter 362 of the Revised Missouri Statutes and, as a result, the
rights of shareholders of Sac River are governed by Missouri law, the Articles
of Agreement of Sac River (the "Sac River Articles"), and the by-laws of Sac
River (the"Sac River By-laws"). If the Merger is consummated, each shareholder
of Sac River will become a shareholder of Bancshares, unless the shareholder
elects to receive cash in exchange for his shares of Sac River Common Stock, as
provided in the Merger Agreement, or exercises dissenters' rights. The following
is a summary of the material differences between the rights of holders of Sac
River Common Stock and the rights of holders of Bancshares Common Stock. These
differences arise from differences between the treatment of corporations and
banks under Missouri law, as well as from differences between the corporate
governing instruments of Bancshares and Sac River.

CAPITAL STOCK

         BANCSHARES. The Bancshares Articles authorize the issuance of 5,000,000
shares of Bancshares Common Stock, of which 511,090 shares were outstanding as
of the date of this Proxy Statement-Prospectus. Bancshares does not have any
authorized shares of preferred stock.

         SAC RIVER. Sac River is authorized to issue 10,000 shares of Sac River
Common Stock, of which 10,000 shares were outstanding as of the date of this
Proxy Statement-Prospectus. Sac River does not have any authorized shares of
preferred stock.

                                       37
<PAGE>   48

PREEMPTIVE RIGHTS

         BANCSHARES. As of the Effective Time, the Bancshares Articles will
provide that when Bancshares issues shares for any reason no Bancshares
shareholder will have any preemptive right to subscribe for or acquire
additional shares of Bancshares capital stock of the same or any other class.
Prior to the Effective Time, Bancshares shareholders have preemptive rights.

         SAC RIVER. The Sac River Articles provide that when Sac River issues
shares for any reason no Sac River shareholder will have any preemptive right to
subscribe for or acquire additional shares of Sac River capital stock of the
same or any other class.

VOTING RIGHTS Of CAPITAL STOCK

         BANCSHARES. Under the Missouri law, unless a corporation's articles of
incorporation provide otherwise, each share of capital stock of the corporation
is entitled to one vote on each matter submitted to a vote of the shareholders.
The Bancshares Articles do not provide otherwise.

         SAC RIVER. Under the Missouri law, unless a corporation's articles of
incorporation provide otherwise, each share of capital stock of the corporation
is entitled to one vote on each matter submitted to a vote of the shareholders.
The Sac River Articles do not provide otherwise.

BOARD OF DIRECTORS

         BANCSHARES. Under the Bancshares Articles, the Bancshares Board of
Directors is to consist of eleven directors. Shareholders elect directors at
each annual meeting and the directors serve until the next annual meeting or
until their successors are duly elected and qualified. As of the Effective Time,
the Bancshares Board of Directors will consist of eighteen directors.

         SAC RIVER. Under the Sac River Articles and By-laws, the Sac River
Board of Directors is to consist of not less than 5 directors nor more than 35
directors. The Sac River Board of Directors currently consists of seven
directors. Shareholders elect directors at each annual meeting of shareholders
and the directors serve until the next annual meeting of shareholders or until
their successors are duly elected and qualified.

CUMULATIVE VOTING

         BANCSHARES. The Bancshares Articles do not provide for cumulative
voting for directors. Thus, under Missouri law, each shareholder who is entitled
to vote at an election of directors has the right to vote the number of shares
owned by him or her for as many persons as there are directors to be elected,
but a shareholder may not cumulate his or her votes for directors.

         SAC RIVER. The Sac River By-laws provide for cumulative voting for
directors. In the election of directors, each shareholder has the right to cast
as many votes in the aggregate as equals the number of voting shares held by the
shareholder, multiplied by the number of directors to be elected at such
election. The shareholder may cast that aggregate number of votes for one
candidate or allocate the votes among more than one candidate.

                                       38
<PAGE>   49

REMOVAL OF DIRECTORS

         BANCSHARES. Bancshares' By-laws provide that any director may be
removed at any time, with or without cause, by the vote of a majority of the
votes cast by the shareholders entitled to vote for the election of directors.

         SAC RIVER. Sac River's Articles and By-laws do not provide for the
removal of directors. Under Missouri law, however, a director may be removed
upon the vote of the holders of a majority of shares entitled to vote at an
election of a director.

FILLING OF VACANCIES ON THE BOARD OF DIrECTORS AND NEWLY CREATED DIRECTORSHIPS

         BANCSHARES. The Bancshares By-laws provide that any vacancy on the
Board of Directors or newly created directorship may be filled by the
affirmative vote of a majority of the remaining directors even though less than
a quorum of the Board, or by a sole remaining director.

         SAC RIVER. The Sac River By-laws provide that vacancies on the Sac
River Board of Directors not exceeding one-third of the whole number of the
Board may be filled by the affirmative vote of a majority of the remaining
directors. Any director so elected will serve until the next election of
directors by the stockholders.

CALL OF SPECIAL MEETiNGS OF SHAREHOLDERS

         BANCSHARES. The Bancshares By-laws provide that special meetings of the
shareholders may be called by the Board, the Chairman of the Board or the
President, and shall be called by the President or the Secretary at the written
demand of a least twenty-five percent (25%) of all outstanding shares entitled
to vote on the action proposed to be taken at such meeting, which demand must
state the purpose or purposes of the proposed meeting.

         SAC RIVER. The Sac River By-laws provide that special meetings of the
stockholders may be called at any time by the Board of Directors or by written
request of the holders of a majority of outstanding capital stock of Sac River.

AMENDMENTS TO ARTICLES OF AGREEMeNT OR ARTICLES OF INCORPORATION

         BANCSHARES. The Articles of Incorporation of Bancshares may be amended
upon the vote of the persons holding the majority of the shares of Bancshares
Common Stock.

         SAC RIVER. Pursuant to Missouri Revised Statutes ss. 362.325, the
Articles of Agreement of Sac River may be amended upon the vote of the persons
holding the majority of the shares of Sac River Common Stock.

AMENDMENTS TO BY-LAWS

         BANCSHARES. The Bancshares By-laws provide that they may be changed or
amended by the vote of a majority of the Board at any regular or special meeting

       INDEMNIFICATION OF BANCSHARES' AND LIBERTY'S DIRECTORS AND OFFICERS

         Bancshares and Liberty have adopted resolutions authorizing
indemnification for the acts or omissions of Bancshares' or Liberty's directors
or officers to the fullest extent allowed under Missouri Revised Statutes
Section 351.355. Section 351.355 allows a corporation to indemnify its officers
and directors against all expenses incurred as a result of any action brought
against such officer or director brought because he was a director or officer of
the corporation, as long as he acted in good faith, in a manner he reasonably
believed to be in the best interests of the corporation, and, with respect to
any criminal proceeding, had no reason to believe his conduct was unlawful.
Bancshares and Liberty provide insurance covering Bancshares' and Liberty's
directors and officers for any losses suffered by them as a result of holding
such position.


                             BUSINESS OF BANCSHARES

GENERAL

         Bancshares is a Missouri corporation formed in 1995 for the sole
purpose of becoming a single bank holding company. Liberty is the only
subsidiary of Bancshares. Although it does not have any present acquisition
plans other than the Merger, Bancshares may acquire additional subsidiaries in
the future, including other banks.

         Liberty is a commercial bank that opened for business in October 1995.
It offers a diversified range of commercial banking services for customers
located principally in Christian, Green, Lawrence and Dade Counties, Missouri.
Liberty's primary market area has a diversified economy, which includes service,
recreation, health care, construction, educational, light industrial, and other
business categories. The market area has enjoyed rapid economic growth in the
last decade. Liberty's services include customary depository products, safe
deposit facilities, commercial, agricultural and personal banking services, and
commercial, construction, consumer, residential real estate, and industrial
lending. Liberty does not intend to change the banking services it offers,
except as market or regulatory conditions may dictate.

         Liberty's principal sources of income are interest on loans,
investments and service fees. Its principal expenses are interest paid on
deposits and general operating expenses.

EMPLOYEES

         At June 1, 1998, Liberty employed 37 full-time and 5 part-time
employees. None of those employees is covered by a collective bargaining
agreement, and management believes that its employee relations are good.

DESCRIPTION OF LIBERTY'S PROPERTY

         The executive offices of Bancshares are located at 1414 East Primrose,
Springfield, Missouri 65804, which is also the main branch of Liberty. The size
of the facility is 4,830 sq. ft., and Liberty owns the facility.

         Liberty operates three (3) branches at the following locations in
Missouri: 2809 East Sunshine, Springfield, Missouri (2,930 sq. ft.); Greenfield,
Missouri (2,940 sq. ft.); and Mount Vernon, Missouri (3,925 sq. ft.). Liberty
owns the building occupied by each branch.

COMPETITION

         Liberty's principal market areas are Christian, Greene, Lawrence and
Dade Counties, Missouri. The competition among depository institutions in this
area is strong. Liberty competes for deposits and loans with local, regional,
and national commercial banks and savings and loan associations that have
facilities in Liberty's market area and with a variety of other financial
intermediaries such as credit unions, mutual funds and brokerage firms. As of
December 31, 1997, Liberty ranked 14th among Springfield area banks in total
assets.

REGULATION AND SUPERvISION OF BANCSHARES

         As a bank holding company, Bancshares is subject to regulation and
supervision by federal and state regulatory authorities, including the Division
of Finance and the FRS Board. Bancshares is required to file semiannual and
annual reports of its operations with the Federal Reserve Board. Under FRS Board
regulations, Bancshares can only conduct banking or bank management activities
or activities closely tied to banking, but cannot conduct activities such as
land development, real estate brokerage, insurance premium funding or any other
activities the FRS Board does not consider closely tied to banking.

REGULATION AND SUPERVISION OF LIBERTY

         As a state bank whose deposits are insured by the FDIC, Liberty is
subject to regulation and supervision by federal and state regulatory
authorities, including the Division of Finance and the FDIC. Virtually every
aspect of Liberty's day-to-day operations are subject to numerous requirements
and restrictions. Applicable laws and regulations, among other things, prescribe
the nature and amount of certain investments, regulate the closure of branch
offices, and limit the amount of, and establish required approval procedures,
reporting requirements and credit standards for, loans and other extension of
credit.  Liberty is also subject to the FDIC's regulatory capital requirements.

         Liberty is required to submit quarterly "Call Reports" to the Division
of Finance and the FDIC, including a balance sheet, an income statement, a
statement of changes in equity capital and report of assets and liabilities. The
Division of Finance also requires Liberty to obtain prior approval of the
Division of Finance to open or operate a branch, to change par value of stock or
to acquire additional subsidiaries. The Division of Finance examines Liberty at
least once per eighteen months to ensure compliance with Division of Finance
regulations.

DIVIDENDS

         Bancshares has not paid any dividends to its shareholders since its
formation. Bancshares does not anticipate declaring cash dividends following the
Merger. Under applicable bank regulations, until October 25, 1998, the third
anniversary of the commencement of its operations, Liberty cannot pay dividends
that would reduce the sum of its Tier I capital plus its loan loss reserve to
less than 8% of its adjusted total assets. After October 25, 1998, Liberty will
not be able to pay dividends that would reduce its Tier I capital to less than
3% of its adjusted total assets, or its Tier II capital to less than 4% of
adjusted total assets, or its risk weighted assets to less than 8% of adjusted
total capital.

LENDING POLICIES

         Liberty makes commercial, consumer and real estate loans to individuals
and businesses. Loans are at both fixed and variable rates of interest. Variable
interest rate loans generally entail less risk because the interest rate adjusts
with the market interest rate, thereby lessening the risk that the interest
earned on a loan will be significantly lower than prevailing market rates over
the life of the loan. The majority of Liberty's commercial and real estate loans
are variable rate loans. The majority of Liberty's consumer loans are fixed-rate
loans. Most of Liberty's consumer loans reprice within one year, substantially
reducing any risks associated with fluctuating interest rates.

         As of December 31, 1997, all of Liberty's construction real estate
loans were variable-rate; 94% of Liberty's mortgage real estate loans were
variable-rate and 79.5% of Liberty's commercial loans were variable-rate loans.
As of December 31, 1997, 99% of Liberty's consumer loans were fixed rate.

         The operations of Liberty include funding commercial real estate,
business and construction loans. These loans involve significant risks compared
with other types of lending. See "Risk Factors-Risks Associated with Commercial
Real Estate, Business and Construction Loans."

         Liberty requires collateral to secure most loans. Real estate loans,
both construction loans and mortgage loans, are secured by the real estate.
Liberty generally requires a loan-to-collateral value of not more than 80% of
the loan value. In the case of one-to-four family residential properties,
Liberty may increase the loan-to-collateral value to 85%. (In certain instances
in which Liberty sells such residential mortgages in secondary market programs,
the loan-to-collateral value may be higher). Commercial loans are generally
secured by inventories and receivables, equipment, machinery, marketable
securities or other liquid financial instruments. Liberty generally requires a
loan-to-collateral value of not more than 85% on commercial loans. Consumer
loans are both secured and unsecured. When secured, the security for these loans
consists of consumer goods, marketable securities, certificates of deposit and
similar items. In most cases, Liberty receives a first lien on collateral
securing loans. In the case of home equity loans, Liberty will take a second
lien on the collateral.

                          BANCSHARES' LEGAL PROCEEDINGS

         As of the date of this proxy statement/prospectus, there are no pending
actions, lawsuits or other legal proceedings involving Bancshares.


                      BANCSHARES' MARKET FOR COMMON EQUITY
                         AND RELATED STOCKHOLDER MATTERS

         There is no established public trading market for the shares of
Bancshares Common Stock. Until the Effective Time of the Merger, a Stock
Purchase Agreement entered into by and among the shareholders of Bancshares in
1995 will restrict the sales of Bancshares Common Stock. That agreement will be
terminated at the Effective Time. To the knowledge of Bancshares' management, in
1997 there was one sale involving 1,000 shares of Bancshares Common Stock at a
price of $10.78 per share. The shares of Bancshares Common Stock involved in the
sale were subject to the Stock Purchase Agreement and the purchase price was
determined in accordance with the terms of the Stock Purchase Agreement. As of
June 30, 1998, outstanding options entitled the holders thereof to acquire
16,000 shares of Bancshares Common Stock.

         Upon the completion of the Merger, Bancshares will have up to 5,000,000
outstanding shares of Bancshares Common Stock. The shares of Bancshares issued
in this Merger will be freely transferable without restriction under the
Securities Act, except for certain restrictions placed on sales by "affiliates"
of Bancshares and Sac River. See "THE MERGER - Resales of Bancshares Common
Stock Issued in the Merger." As of the date of this Proxy Statement-Prospectus,
approximately 235,850 outstanding shares of Bancshares Common Stock were held by
affiliates of Bancshares and approximately 275,240 shares were held by
nonaffiliates of Bancshares.

         As of June 30, 1998, the outstanding shares of Bancshares Common Stock
were held of record by 36 persons.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  CONSOLIDATED FINANCIAL CONDITION AND RESULTS
                       OF OPERATIONS OF LIBERTY BANCSHARES

         The following discussion of financial condition and results of
operations should be read in conjunction with the consolidated financial
statements of Liberty Bancshares and the related notes. As used in the following
discussion, the term "Company" refers to Liberty Bancshares and its subsidiary
on a consolidated basis; the term "Bank" refers to Liberty Bank; and the term
"Liberty Bancshares" refers to Liberty Bancshares, Inc., on a parent company
only basis.

                                                        
RESULTS OF OPERATIONS

GENERAL

         Bancshares has enjoyed rapid growth since its commencement of
operations in late October 1995. Total assets increased from $12,223,000 at
December 31, 1995, to $111,462,000 at June 30, 1998, or 811.9%. This growth is
reflected in all aspects of changes in the Company's financial condition from
1996 to 1997 and in the period ended June 30, 1998, and in the results of the
Company's operations in those periods. (The following discussion does not
address results of operations in the 65 days ended December 31, 1995, and the
year ended December 31, 1996, because the periods are not susceptible to
meaningful comparison). This growth is the result of a number of factors,
including the opening of new branches, hiring of experienced lending officers
seeking new positions after mergers of large banks that serve the Springfield
area, the addition of depositors as a result of those bank mergers, the economic
vitality of the Springfield area, and the Bank's marketing program.

         The Bank's rapid growth has required the injection of additional
capital from time to time to ensure that the Bank remains well capitalized. (See
"Selected Information of Bancshares" for historical information about the Bank's
capital position for regulatory purposes.) Bancshares has provided additional
capital for the Bank by borrowing under its line of credit and by issuing
additional shares of capital stock to Bancshares' existing shareholders. In May
1998, Bancshares borrowed $875,000 under its line of credit and issued $375,000
of additional shares of Bancshares Common Stock. Bancshares contributed the
resulting $1,250,000 to the Bank's capital. At June 30, 1998, Bancshares'
$4,500,000 line of credit had $4,125,000 of outstanding borrowings.

FINANCIAL CONDITION

TOTAL ASSETS

         The Company's total assets increased from $31,590,000 at December 31,
1996, to $80,025,000 at December 31, 1997, or 153.3%. This increase was driven
by the growth of total deposits during the period.
         At June 30, 1998, total assets were $111,462,000, a $60,601,000, or
119.2%, increase over the same date a year earlier, and 

<PAGE>   63



$31,437,000, or 39.3%, greater than total assets at December 31, 1997. Again,
increases in deposits underlay the increase in total assets.


NET LOANS

         Loans net of loan allowances were the principal component of
Bancshares' asset growth. Net loans increased from $19,285,000 at December 31,
1996, to $51,129,000 at December 31, 1997, or 165.1%. At June 30, 1998, net
loans were $79,499,000, an increase of $43,760,000, or 122.4%, over net loans at
June 30, 1997, and a $28,370,000, or 55.5%, increase over net loans at December
31, 1997.

INVESTMENT SECURITIES

         The growth in investment securities was a result of the rapid increase
in the Bank's deposits, which were not fully absorbed by loan production. The
increase from December 31, 1996, to December 31, 1997, was $10,817,000, or
747.0%. The increase from June 30, 1997, to June 30, 1998, was $12,529,000, or
343.9%, and from December 31, 1997, to June 30, 1998, was $3,907,000, or 31.9%.

DEPOSITS

         Deposits grew as a result of the Bank's opening new branches and its
marketing efforts as well as the addition of customer deposits of new borrowers
and individuals and businesses moving their accounts in the aftermath of bank
mergers that affected the Springfield market. Total deposits at December 31,
1998, were $64,585,000, a $37,276,000, or 136.5%, increase over $27,309,000 at
December 31, 1996. At June 30, 1998, total deposits were $90,495,000, an
increase of $47,188,000, or 108.9% from June 30, 1997. Total deposits at June
30, 1998, also were $25,910,000, or 40.1%, greater than those at December 31,
1997.

SHORT-TERM BORROWINGS

         Short-term borrowings, which were primarily repurchase agreements and a
bank note payable, also paralleled the Bank's growth, rising from $600,000 at
December 31, 1996, to $9,700,000 at December 31, 1997, a $1,516.7 increase.
Similarly, short term borrowings rose from $2,184,000 at June 30, 1997, to
$14,095,000 at June 30, 1998, a 545.4% increase.

         The primary purpose of the bank note payable, which was $4,125,000 at
June 30, 1998 and $2,500,000 at December 31, 1997, was to increase capital at
the subsidiary bank.

STOCKHOLDERS EQUITY

         As a result of both growth of retained earnings and sales of Bancshares
Common Stock to existing stockholders, Bancshares' stockholders' equity
increased by $1,729,000, or 48.6%, from $3,559,000 at December 31, 1996, to
$5,288,000 at December 31, 1997. At June 30, 1998, stockholders' equity was
$6,322,000, a $2,738,000, or 76.4% increase over the 

                                       53
<PAGE>   64

amount at June 30, 1997, and a $1,034,000, or 19.6%, increase over stockholders'
equity at December 31, 1997.

RESULTS OF OPERATIONS

NET INCOME

         Since Bancshares' sole subsidiary is a newly formed bank, the Company's
income and returns on average assets and stockholders' equity have lagged those
of longer established comparably sized institutions. For the year ended December
31, 1997, net income was $166,000, an increase of $72,000, or 76.6%, over
$94,000 in the prior year. As a result of the costs of opening two new branches
in 1997 plus the addition of retail and secondary market home loan servicing
departments in the same year, average return on assets declined from .47% for
1996, to .31% for 1997, and return on average shareholders' equity increased
only slightly from 2.69% to 3.63%.

         Net income for the six months ended June 30, 1998, was $293,000,
compared to $138,000 for the same period a year earlier, a 112.3% increase. As a
result of the increase in the Bank's assets, return on average assets increased
to .76% for the six months ended June 30, 1998, over .69% in the same period a
year earlier, and return on shareholders' equity grew to 12.19% from 7.85%.

         The Company's net income growth has been restrained by the need to
build the Bank's provision for loan losses to an amount equal to 1% of the
Bank's total loans (less the SBA guaranteed portion of loans and less loans 
secured by borrowers' deposits at the Bank). Under applicable bank
regulations, the Bank had three years from inception to reach the 1% level. At
June 30, 1998, the Bank's allowance for loan losses equaled that level.

INTEREST INCOME

         The Company's interest income has increased with the Bank's asset
growth. Interest income in the year ended December 31, 1997, was $3,948,000, a
$2,564,000, or 185.3%, increase over the prior year. For the six months ended
June 30, 1998, the increase was $2,088,000, or 143.4%, over the same period a
year earlier.

INTEREST EXPENSE

         Interest expense primarily reflected the growth in the Bank's interest
bearing deposits. Interest expense in the year ended December 31, 1997, was
$2,131,000, an increase of $1,456,000, or 215.7%, over the prior year. For the
six months ended June 30, 1998, interest expense was $1,953,000, an increase of
$1,196,000, or 158.0% over the same period a year earlier.

NONINTEREST INCOME AND EXPENSE

         Noninterest income has been provided primarily by overdraft charges,
account servicing charges, safe deposit box fees, and other sources. While not
material in comparison to interest income, noninterest income grew by 327.7% in
the year ended December 31, 1997, over the prior year, and by 

                                       54
<PAGE>   65

144.3% in the six months ended June 30, 1998, over the same period in the prior
year.

         Noninterest expense includes the cost of operations, including overhead
and expenses associated with the opening of new branches and departments in the
Bank, including the costs of additional personnel. For the year ended December
31, 1997, when the Bank opened two branches and added two departments,
noninterest expense was $1,288,000, an increase of $736,000, or 133.3%, over the
prior year. In the six months ended June 30, 1998, noninterest expense was
$1,097,000, an increase of $621,000, or 130.5%, over the same period a year
earlier.

NET INTEREST INCOME

         Net interest income, the primary source of earnings for the Company, is
the difference between interest income earned on loans and other earning assets,
and interest paid on deposits and other interest bearing liabilities. Earning
assets include loans, investment securities and federal funds sold. Interest
bearing liabilities include interest-bearing deposits (NOW accounts, MMDA,
savings and others), time deposits, federal funds purchased and securities sold
under agreements to repurchase.

         The following table sets forth the Company's average balance of assets,
liabilities and stockholders' equity as well as the amount of interest income or
interest expense and the average rate for each category of interest earning
assets and interest bearing liabilities. Included in the average balances are
non-accruing loans. Loan fees are included in interest income. Average balances
are computed on a daily basis.

(1)  Includes non-interest bearing balances, cash and cash items. 
(2)  Loans, net of loan losses.
(3)  Net interest yield is net interest earnings divided by total
     interest-earning assets, with net interest earnings equal to the difference
     between total interest earned and total interest paid.



         During 1997, average deposit growth, particularly time deposits,
exceeded the growth of loans. Total average interest bearing liabilities grew by
194.6% in 1997 over 1996, and total average interest earning assets grew at a
less rapid 169.8% in the same period. The difference reflected, in part, the
opening of new branches and the addition of new depository accounts as a result
of large bank mergers

that affected the Springfield market area. The net interest spread over that
time period was virtually unchanged and the net interest yield declined by 5.1%
to 3.56%.

         The effect of changes in average balance and rate from the 
corresponding prior period on interest income, interest expense and net interest
income for the year ended December 31, 1997 is set forth below. The effect of a
change in average balance has been determined by applying the average rate for
the earlier period to the change in the average balance for the later period, as
compared with the earlier period. The effect of a change in the average rate has
been determined by applying the average balance for the earlier period to the
change in the average rate for the later period, as compared with the earlier
period. The variances attributable to simultaneous balance and rate changes have
been allocated in proportion to the relationship of the dollar amount of change
in each category.

</TABLE>


         The 166.8% increase in total loans generally reflects the rapid
increase in the Bank's deposit base, the demand for loans in the Bank's market
area, and the Bank's marketing efforts, which were enhanced by the addition of
experienced lending officers hired from other area banks.

         Real estate construction loans consist primarily of residential and
commercial construction loans for properties located in Greene County, Missouri.
Real estate mortgage loans, including 1-4 family and multi-family loans, are
collateralized by residential properties that are principally located in Greene
County, Missouri. Real estate-non-farm, non-residential loans are secured by
commercial properties principally located in Greene County, Missouri.

         Commercial and industrial loans are comprised primarily of loans to
customers in the southwest Missouri trade area and are diversified from an
industry and customer standpoint, which helps to minimize risk. Consistent with
management's emphasis on relationship banking, most borrowing customers also
maintain deposit accounts and utilize other banking service.

         The consumer loan portfolio consists of both secured and unsecured
loans to individuals for various personal reasons such as automobile financing,
home improvements, education and recreational purposes.

         The Company's loan portfolio is varied, with no undue concentration in
any single industry, although most of the loans in the Company's portfolio have
been made to borrowers in the Greene County area.

RISK ELEMENTS OF LOAN PORTFOLIO

         Management reviews the Company's loan portfolio continuously for
problem loans. During the ordinary course of business, management becomes aware
of borrowers that may not be able to meet contractual requirements of loan
agreements. Such loans are placed under close supervision, with consideration
given to placing the loan on a nonaccrual status. Management then determines the
need for additions to the allowance for loan loss or, if appropriate, partial or
full charge-off. Those loans on which management does not expect to collect
interest in the normal course of business, or which are 90 days or more past due
as to principal or interest, are generally placed on nonaccrual status. After a
loan is placed on nonaccrual status, interest income is recognized only on a
cash basis so long as management is satisfied there is not impairment of the
book value of the loan. The loan is returned to accrual status only when the
borrower has brought all past due principal and interest payments current, and
in the opinion of management, the borrower has demonstrated the ability to make
future payments of principal and interest as scheduled.

         It is the Bank's stated policy that when a loan becomes over 90 days
delinquent, it is automatically placed on nonaccrual status. In addition, other
loans showing a high apparent risk and potential for deterioration in financial
strength or collateral value may be placed on a nonaccrual status.

         As of June 30, 1998 and December 31, 1997, the gross interest income on
loans recorded for the period then ended was $2,955,737 and $3,130,609. The
amount of interest income on the above-referenced loans accounted for in
nonaccrual status that would have been recorded during such year if such loans
had been current in accordance with their terms was $0 for both periods.

         As of December 31, 1996, the gross interest income on loans recorded
for the year then ended was $995,765. The amount of interest income on the
above-referenced loans accounted for in nonaccrual status that would have been
recorded during such year if such loans had been current in accordance with
their terms was $0.

PROVISION FOR LOAN LOSSES

         The provision for loan losses represents management's determination of 
the amount necessary to be charged against the current period's earnings, in
order to maintain the allowance for loan losses at a level which is considered
adequate, in relation to the estimated risk inherent in the loan portfolio.
Since the Bank was formed in 1995, it has been building its loan loss reserves
up to 1% of total loans. The loan loss reserve (which is total loans less Small
Business Administration guaranteed loans and loans secured by deposits at
Liberty) at December 31, 1997, and June 30, 1998 equaled the 1% level.
Notwithstanding the process of building a loan loss reserve, management believes
its provision for loan losses has been sufficient since 1995. See "Financial
Condition - Allowances for Loan Losses."

         The following table presents an analysis of the Company's loss
experience for the periods indicated.

ALLOWANCE FOR LOAN LOSSES

         The allowance for loan losses is established through a provision for
loan losses based on management's evaluation of the risk inherent in its loan
portfolio and the general economy. Such evaluation, which includes a review of
all loans on which full collectibility may not be reasonably assured, considers
among other matters, the estimated fair value of the underlying collateral,
economic conditions, historical loan loss experience, and other factors that
warrant recognition in providing for an adequate loan loss allowance. In
addition, various regulatory agencies, as an integral part of their examination
process, periodically review the Bank's allowance for loan losses and valuation
of foreclosed assets held for sale. Such agencies may require the Bank to
recognize additions to the allowance based on their judgments about information
available to them at the time of their examination.

         Management has established an allowance for loan losses which reduces
the total loans outstanding by an estimate of potential loan losses, plus an
excess margin for potential future uncertainties. Loans deemed uncollectible are
charged against and reduce the allowance. Provisions for loan losses are
expensed against current income. The provision replenishes the allowance for
loan losses and maintains the allowance at acceptable levels based upon the
judgment of management. The allowance for loan losses is based upon current
economic conditions, risks in the loan portfolio, historical loan loss
experience and other factors which, in management's opinion, deserve current
recognition. See "-Results of Operations-Provision for Loan Losses."

DEPOSITS

         The Bank's deposit base is its primary source of funds. The Bank offers
a broad range of deposit products, including noninterest demand deposits, NOW
accounts, saving deposits, individual retirement accounts and certificates of
deposit.

         At December 31, 1997, 17.1% of total deposits were in noninterest
bearing accounts, 25.2 % in savings and interest bearing demand accounts and
57.7% in certificates of deposit.

SHORT-TERM BORROWINGS

         Short-term borrowings consist mainly of federal funds purchased and
securities sold under agreements to repurchase. These amounted to $7,200,361 at
December 31, 1997, and $600,000 at December 31, 1996. The average yield on
short-term borrowings was 4.96% and 5.36% during 1997 and 1996, respectively.
The majority of these investments have terms ranging from one to 30 days. The
maximum amounts of short-term borrowings outstanding at any month end during
1997 and 1996 were $10,645,000 and $950,200. Information regarding the levels of
short-term borrowings for 1997 and 1996 are as follows:

LIQUIDITY AND CAPITAL RESOURCES

         Liquidity risk is managed by the Company through the composition of its
assets and liabilities in an effort to meet efficiently the borrowing needs and
withdrawal requirements of its customers. Cash and cash equivalents include
cash, due from banks and federal funds sold. The primary sources of the

                                       66

<PAGE>   77





Company's liquidity are cash and cash equivalents, investment securities with
short-term maturities, $375,000 of remaining availability on its letter of
credit and the Bank's unsecured $1,300,000 line of credit (under which there
were no outstanding borrowings at December 31, 1997 and March 31, 1998).

         Although the Company has a relatively high volume of its loans and
certificates of deposit (CD'S) that mature in one year or less, the company
believes its CD's, which are used primarily to fund loans, are a relatively
stable source of funds. Since the Bank's inception, a large majority of the
loans and certificates of deposit originated by the Bank have been renewed at
maturity. In addition, the Bank has been and continues to be competitive on
interest rates for both loans and CD's.

         If a significant portion of CD's were not replaced, the Bank could draw
on its $1,675,000 available lines of credit or it could utilize borrowings
available to it from the Federal Home Loan Bank (the Bank recently became a
member). It could also raise CD rates to stay competitive in the marketplace.
The Bank could also sell investment securities, which are all classified as
available-for-sale, to the extent they are not pledged for public funds.

         The Company can also increase its liquidity by causing the Bank to sell
SBA guaranteed loans and participations in commercial loans. The Company
believes its process of asset/liability management allows adequate reaction time
for trends in the marketplace as they occur, minimizing the negative impact of
such trends on the net interest margin.

         If a significant amount of loans that mature over the next year were
not renewed, the Bank could participate in loans originated by other financial
institutions, it could increase its investments in securities, or it could lower
interest rates charged on loans to remain competitive in its marketplace.

         Cash flows from operating activities for the periods covered by the
Statements of Cash Flows relate primarily to net income adjusted for changes in
deferred assets, accrued interest receivable, credits and other liabilities, the
provision for loan losses, depreciation and the amortization of discounts
(premiums) on investments, all of which are non-cash or non-operating
adjustments to operating cash flows. Depreciation has increased steadily due to
the growth of the Bank since its inception. Three additional branches have been
opened since that time. Due to the growth in the loan portfolio, accrued
interest receivable has also grown significantly. Operating activities provided
cash flows of $363,000 and $446,000 for the period ending June 30, 1998 and the
year ended December 31, 1997, respectively. Operating activities used cash flows
of $429,000 for the year ended December 31, 1996, primarily due to loans
originated for resale but not funded at December 31, 1996.

         During the six months ended June 30, 1998 and the years ended December
31, 1997 and 1996, investing activities used cash of $32.9 million, $43.7
million, and $16.7 million primarily due to the increases in loan, purchases of
premises and equipment, and purchases of available-for-sale securities in each
period.

         Cash flows from financing activities increased during the six months
ended June 30, 1998, and the years ended December 31, 1997 and 1996, due to
increases in deposits after interest credited, increases in short-term
borrowings and increases in note payable. In addition, cash flows increased due
to issuance of additional shares during 1997 and 1998. Financing activities
provided cash of $31.1 million for the period ending June 30, 1998, and $47.9
million and $19.2 million for the years ending December 31, 1997 and 1996.
                                                     
YEAR 2000

         Liberty relies upon computer hardware, software, and data processing
services to operate and maintain customer accounts, loan accounts, investments,
ATM systems, and other core functions. Other non-core functions also use
software and embedded microprocessor technology. Both core and non-core
functions are susceptible to the "Year 2000" problem, which means that software
and microprocessors will report January 1, 2000, and subsequent dates as January
1, 1900, or other incorrect twentieth century dates. This incorrect dating could
make it very difficult for Liberty to conduct business electronically.

                  Third party suppliers provide Liberty with many of these
electronic services. (Many of Liberty's suppliers provide the same services to
Sac River, and as a result Liberty and Sac River have developed similar programs
for dealing with Year 2000 issues.) Liberty also owns or leases other
information technology, including equipment with embedded technology that
control various systems within the bank.

         Liberty has formed a committee of bank employees to assess and
coordinate the bank's Year 2000 compliance. On a quarterly basis the committee
reports to Liberty's Board of directors on the status of the bank's compliance
efforts. Since its formation in 1997, the committee has undertaken the following
activities, among others:

o        Identifying software and equipment that may not be Year 2000 compliant.
o        Seeking certificates of compliance from vendors.
o        Identifying borrowers who have Year 2000 problems and seeking 
         information from them about the extent of their compliance efforts.


<PAGE>   79
- -        Arranging test schedules with vendors and conducting tests of
         owned and leased equipment.
- -        Contacting local utilities to determining their ability to
         provide electricity, water, and gas service after December 31,
         1999.
- -        Installing compliant versions of core technologies provided by the 
         bank's vendors.
- -        Preparing a liquidity plan.
- -        Preparing a contingency plan.
- -        Ordering or installing equipment with compliant embedded technology.
- -        Mailing brochures to all customers advising them about some of 
         Liberty's plans for dealing with Year 2000 issues.
- -        Assessing other commercial customers' Year 2000 readiness.

         As of August 1998, Liberty's core data processing system and teller
software were Year 2000 compliant and have been extensively tested by their
vendors. Liberty also intends to conduct its own tests of these systems. In
addition, the bank's software for communication with the Federal Reserve was
compliant following upgrades. Tests of the bank's ATM software will occur before
the end of 1998. All of the bank's personal computers loan processing software
is compliant.

         Liberty intends to have all remaining software and technology compliant
and fully tested by June 30, 1999.

         Third party vendors have borne most of the cost of making Liberty Year
2000 compliant. Costs incurred by Liberty have largely been in the form of the
compensation and benefits provided existing bank employees who have conducted
the compliance activities. Liberty hired no consultants or new employees to
achieve Year 2000 compliance, and it has not allocated employee compensation and
benefit expense to the project. To date, Liberty has not incurred any
non-employee expenses in implementing its compliance program and expects that
its total non-employee costs through January 1, 2000, will be $5,000 or less.

         While Liberty believes that its systems and technology will be
compliant on January 1, 2000, and thereafter, it faces an unquantifiable risk
that third parties such as customers will encounter Year 2000 problems that
cause them to reduce their use of bank services, default on loans, or reduce
levels of future borrowings. There is also a risk that other financial
organizations with which Liberty maintains relations could experience Year 2000
issues that would adversely affect Liberty. Finally, if other service providers,
such as public utilities or telephone companies, are not Year 2000 compliant, 
the bank could experience service interruptions that would make the conduct of 
business difficult.

         Liberty has developed a contingency plan to address some of these
uncertainties. It will employ back-up generators as needed to provide electric
power beginning on January 1, 2000. It will also have in place a cellular based
modern communication system to maintain communication with its data service
providers in the event that landline communications are disrupted. Immediately
before the change of the century, electronic trial balances with extended
information will be downloaded for import into local database files. There will
also be a complete backup of all files before the century change, and critical
information will be printed in hardcopy. The bank will take other steps to
assure both liquidity and security.


                                       69
<PAGE>   80
         In summary, Liberty believes that it has completed about 90% of the
actions necessary to achieve Year 2000 compliance for its core systems and 50%
of the work necessary to achieve overall compliance. Liberty expects that it
will complete the rest of the program before the century date change. There
remains, however, the possibility that problems encountered by third parties
could adversely affect the bank.

INTEREST RATE SENSITIVITY

         Asset and liability management encompasses both interest rate risk and
liquidity management. The Company's net interest margin can be vulnerable to
wide fluctuations arising from a change in the general level of interest rates
which may affect the yield on interest earning assets differently than the cost
of the interest bearing liabilities. The Company monitors its asset and
liability mix in an effort to maintain a consistent earnings performance through
control of interest rate risk.

         Below is the "Static gap" table for the Company as of December 31,
1997. This is just one of several tools which may be used to measure and manage
interest rate sensitivity. Earning assets and interest bearing liabilities are
presented below within selected time intervals based on their repricing and
maturity characteristics. In this view, the sensitivity position is perfectly
matched when an equal amount of assets and liabilities reprice during any given
period. Excess assets or liabilities repricing in a given time period result in
the "Interest Sensitivity Gap" shown at the bottom of the table. A positive gap
indicates more assets than liabilities will reprice in that time period, while a
negative gap indicates more liabilities than assets will reprice.

         The table indicates the Company is liability sensitive in the after
three months through twelve months period and is asset sensitive in all other
periods. This means that during the after three months through twelve months
period, interest bearing liabilities are repricing faster than earning assets,
thereby improving net interest income when rates are declining and reducing net
interest income when rates are rising. While the "static gap" is a widely used
measure of interest sensitivity, it is not, in management's opinion, the only
indicator of the Company's sensitivity position.

         The following table indicates as of December 31, 1997, the time period
in which interest earning assets and interest bearing liabilities are scheduled
to mature or reprice in accordance with their contractual terms.

</TABLE>




         An interest sensitivity table is not a complete picture of the possible
effect of interest rate changes on net interest income. First, changes in the
general level of interest rates will not affect all categories of assets and
liabilities equally or simultaneously. Second, the table represents a one-day
position; variations occur daily as the Company adjusts its interest sensitivity
throughout the year. Third, the repricing distribution of interest sensitive
assets may not be indicative of the liquidity of those assets. Finally, since
this table is based on contractual maturities, it does not include required
principal payments or estimates of early principal payments on residential
mortgages, installment loans and investment securities.

CAPITAL ADEQUACY

         Stockholders' equity represented 5.67% of total assets at June 30,
1998. Risk-based capital and leverage ratios of the Bank exceeded minimum
requirements of regulatory banking authorities.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         The FASB recently adopted Statement of Financial Accounting Standards
("SFAS") 128, "Earnings Per Share." This statement replaces the presentation of
primary earnings per share with a presentation of basic earnings per share. The
statement also requires dual presentation of basic and diluted earnings per
shares by entities with complex capital structures and requires a reconciliation
of the numerators and denominators between the two calculations. SFAS 128 is
effective for financial statements issued for periods ending after December 15,
1997, including interim periods. Management has presented earnings per share in
accordance 

                                       71


<PAGE>   82

with SFAS 128 in its December 31, 1997 financial statements. The adoption of
SFAS 128 did not have a material impact on the Company's financial statements.

         The FASB recently adopted SFAS 129, "Disclosure of Information about
Capital Structure." This statement establishes standards for disclosing
information about capital structure, including pertinent rights and privileges
of various securities outstanding. SFAS 129 is effective for financial
statements issued for periods ending after December 15, 1997. The adoption of
SFAS 129 did not have a material impact on the Company's financial statements.

         The FASB recently adopted SFAS 130, "Reporting Comprehensive Income."
This statement establishes standards for reporting and display of comprehensive
income and its components, in a full set of financial statements. It does not
address issues of recognition or measurement. SFAS 130 is effective for fiscal
years beginning after December 15, 1997. The adoption of SFAS 130 did not have a
material impact on the Company's financial statements.

         The FASB recently adopted SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information." This statement establishes standards for
the way that public business enterprises report information about operating
segments in both annual financial statements and interim financial reports
issued to shareholders. The statement also establishes standards for related
disclosures about products and services, geographic areas and major customers.
SFAS 131 is effective for financial statements issued for periods beginning
after December 15, 1997. The adoption of SFAS 131 is not expected to have a
material impact on the Company's financial statements.

         The FASB recently adopted SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments and for hedging activities. SFAS
133 is effective for all fiscal quarters of fiscal years beginning after June
15, 1999. Management has not yet determined the impact, if any, of SFAS 133 on
the Company's financial statements.


EFFECT OF ECONOMIC CONDITIONS

         The Company's financial statements have been prepared in accordance
with generally accepted accounting principles, which require the measurement of
financial position and operating results in terms of historical dollars without
consideration for changes in the relative purchasing power of money over time
due to inflation. The assets and liabilities of the Company are primarily
monetary and interest rates have a greater impact on the Company's performance
than does the effect of inflation. The local economy of the southwest Missouri
area has experienced growth over the last several years. The area has a good mix
of retail, agricultural related and industrial business.

                              BUSINESS OF SAC RIVER

GENERAL

         Sac River is a state bank organized in Missouri in 1912, located in
Stockton, Missouri, which is approximately 65 miles northeast of Springfield and
has a population of approximately 1,050. Sac River's primary market area is
largely rural, containing agricultural, light industrial, recreational and
vacation oriented businesses and businesses that cater to the large retired
population. Sac River's market area has experienced moderate growth and stable
economic conditions in the last decade. Sac River offers


                                       72

<PAGE>   83

a full range of commercial banking services including customary depository
products, safe deposit facilities, and commercial, consumer, residential real
estate, agricultural and industrial lending.

EMPLOYEES

         As of June 1, 1998, Sac River employed 24 full-time employees. None of
these employees is covered by a collective bargaining agreement and management
believes that its employee relations are good.

DESCRIPTION OF SAC RIVER'S PROPERTY

         The executive offices of Sac River are located at 14 Public Square,
Stockton, Missouri, which is also the location of Sac River's only banking
facility. Sac River owns the property and the building at this location, as well
as two adjacent buildings, currently vacant, and adjacent parking lots. In
addition, Sac River owns 1.9 undeveloped acres south of Stockton.

COMPETITION

         Sac River's principal market area is within a 20 mile radius of
Stockton and includes portions of Cedar, Dade, Polk, Barton and Vernon Counties,
Missouri. In recent years, Sac River has also become a lender in the Springfield
market. The competition among depository institutions in the Stockton area is
strong. Sac River competes for deposits and loans with Tri-County State Bank and
Great Southern Bank, a savings association, both of which have branches in
Stockton. Sac River also competes in the Stockton area with a number of other
area, regional, and national commercial banks and savings and loans associations
and a variety of other financial intermediaries such as credit unions, mutual
funds and brokerage firms. In Springfield, Sac River competes for loans with a
large number of local, regional, and national banks and financial institutions.
Many of these competing institutions are much larger and have more resources
than Sac River. Sac River competes by providing personal service, pricing of
interest rates, advertising, and referrals from its customers.
    
REGULATION AND SUPERVISION OF SAC RIVER

         Sac River is subject to regulation and supervision by the Division of
Finance, the FDIC and the FRS Board. Virtually every aspect of Sac River's
day-to-day operations are subject to numerous requirements and restrictions. Sac
River is subject to laws and regulations that, among other things, prescribe the
nature and amount of certain investments, regulate the closure of branch
offices, and limit the amount of, and establish required approval procedures,
reporting requirements and credit standards for, loans and other extension of
credit. Sac River is also subject to the FDIC's and the FRS Board's regulatory
capital requirements. Sac River submits quarterly "Call Reports" to the FDIC.
See "BUSINESS OF BANCSHARES - Regulation and Supervision of Liberty. The FRS
Board examines Sac River for safety and soundness at least once every two years.

         In addition, Missouri law regulates the day to day activities of Sac
River, including deposit taking, lending and investment activities. The Division
of Finance and the FRS Board share results of their yearly examinations. The
Division of Finance examines Sac River at least every two years.

         Sac River has paid dividends to its shareholders yearly for over forty
years. In 1997, Sac River paid dividends of $80 per each share of Sac River
Common Stock.

LENDING POLICIES


         Sac River makes commercial, consumer and real estate loans to
individuals and businesses. Loans are at both fixed and variable rates of
interest. Variable interest rate loans generally entail less risk because the
interest rate adjusts with the market interest rate, thereby lessening the risk
that the interest earned on a loan will be significantly lower than prevailing
market rates over the life of the loan. The majority of Sac River's commercial
and real estate loans are variable rate loans. Slightly more than half of Sac
River's consumer loans are fixed-rate loans. Most of Sac River's consumer loans
reprice within one year, substantially reducing any risks associated with
fluctuating interest rates.

         As of December 31, 1997, 80% of Sac River's mortgage real estate loans
were variable-rate, 93% of Sac River's commercial were variable-rate and 57% of
Sac River's consumer loans were variable-rate.

         The operations of Sac River include funding commercial real estate,
business and construction loans. These loans involve significant risks compared
with other types of lending. See "Risk Factors-Risks Associated with Commercial
Real Estate, Business and Construction Loans."

         Sac River requires collateral to secure most loans. Real estate loans,
both construction loans and mortgage loans, are secured by the real estate. Sac
River generally requires a loan-to-collateral value of not more than 80% of the
loan value. Commercial loans are generally secured by inventories and
receivables, equipment, machinery, marketable securities or other liquid
financial instruments. Sac River generally requires a loan-to-collateral value
of not more than 85% on commercial loans. Consumer loans are both secured and
unsecured. When secured, the security for these loans consists of consumer
goods, marketable securities, certificates of deposit and similar items. In most

CERTAIN BUSINESS RELATIONSHIPS

         At December 31, 1997 and 1996, Sac River had loans outstanding to
officers, directors, employees and companies in which the bank's executive
officers or directors were principal owners, in the amount of $624,000 and
$562,000, respectively.

         Such loans and other extensions of credit and deposits were made in the
ordinary course of business and were made on substantially the same terms
(including interest rates and collateral) as those prevailing at the time for
comparable transactions with other persons. Further, these loans did not involve
more than normal risk of collectibility or present other unfavorable features.

with a company that was controlled by Garry Robinson. The agreement called for

Expense recognized by the Bank relating to this agreement was $161,513 and
$40,770 for 1997 and 1996, respectively. Included in the 1997 expense was a
payment of $66,000 made to terminate the contract effective December 31, 1997.
Fees under the agreement were set at a rate of 1/2% per month on the outstanding
balance of all loans serviced.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                         FINANCIAL CONDITION AND RESULTS
                           OF OPERATIONS OF SAC RIVER

         The following discussion of financial condition and results of
operations should be read in conjunction with the financial statements of Sac
River and the related notes. As used in the following discussion, the term
"Bank" refers to Sac River.

GENERAL

         Sac River's Stockton market area has not experienced the rapid
population and economic growth of the Springfield area. Nonetheless in 1997, two
other banking institutions opened branches in the Stockton market area,
increasing competitive pressures on Sac River.

FINANCIAL CONDITION

TOTAL ASSETS

         Sac River's total assets at December 31, 1997, were $103,044,000, an
increase of $10,509,000, or 11.4%, over total assets of $92,535,000 at December
31, 1996. $6,124,000 of this increase resulted from the proceeds of repurchase
agreements with Liberty Bank and another southwest Missouri bank. Under these
agreements, Sac River sold Liberty Bank and the other institution securities
subject to Sac River's obligation to repurchase the securities on a specified
date. The balance of the increase in Sac River's assets reflected growth in
local deposits.

         For the six months ended June 30, 1998, Sac River's total assets were
$90,944,000, a decrease of $1,553,000, or 1.7%, over the same period in the
prior year. This decrease reflected changes in both the repurchase agreements
with Liberty Bank and the other financial institution. Total assets at June 30,
1998, were lower by $12,100,000, or 11.7%, over total assets at December 31,
1997. This decrease also primarily reflected a reduction of the level of
repurchase agreements with Liberty Bank.


NET LOANS

         Sac River's loans net of loan allowances grew by $2,436,000, or 4.0%,
from December 31, 1996, to December 31, 1997, and by $5,001,000, or 8.5%, from
June 30, 1997, to June 30, 1998. At June 30, 1998, net loans were $649,000, or
1.0% greater than the level at December 31, 1997.

INVESTMENT SECURITIES

         Sac River's total investment securities increased $6,911,000, or 30.3%,
to $29,696,000 at December 31, 1997, from $22,785,000 at December 31, 1996. This
increase largely reflected Sac River's investment of the proceeds of repurchase
agreements with Liberty Bank and the other southwest Missouri bank. For the six
months ended June 30, 1998, investment securities totaled 



                                       83

<PAGE>   94


$17,218,000, a decrease of $8,052,000, or 31.7%, over $25,270,000 of investment
securities at June 30, 1997. At June 30, 1998, investment securities were
$12,478,000 lower than six months earlier at December 31, 1997. Both of these
decreases reflected Liberty Bank's liquidation of some of its repurchase
agreements with Sac River to make funds available for loan production.

DEPOSITS

         Sac River's deposits increased slightly from December 31, 1996, to
December 31, 1997, rising to $73,999,000 from $72,903,000, or 1.5%. From June
30, 1997, to June 30, 1998, total deposits decreased by $1,241,000, or 1.7%, to
$73,642,000 reflecting a stable deposit base during the periods.

SHORT-TERM BORROWINGS

         Sac River's short-term borrowings grew from $8,751,000, at December 31,
1996, to $14,875,000 at December 31, 1997, an increase of 70.0%. For the six
months ended June 30, 1998, short-term borrowings were $1,178,000 compared to
$6,339,000 on the same date a year earlier, a decrease of 81.4%. At June 30,
1998, short-term borrowings were 92.1% lower than at December 31, 1997. The
increase in short-term borrowings in 1997 resulted from the increase in the
amount of repurchase agreements with Liberty Bank and the other southwest
Missouri bank, while the decrease in the first six months of 1998 reflected both
of those bank's reduction of the amount of repurchase agreements with Sac River.

STOCKHOLDERS' EQUITY

         The $786,000 growth in Sac River's stockholders' equity in 1997
paralleled Sac River's net income after payment of dividends, while the $421,000
increase from June 30, 1997 to June 30, 1998, reflected the effect of the
payment of $800,000 of dividends in 1998 compared to $400,000 in 1997.


RESULTS OF OPERATIONS

NET INCOME

         Sac River's net income for the year ended December 31, 1997, decreased
slightly to $1,584,000 from $1,626,000 for the year ended December 31, 1996. The
$42,000 decrease resulted from narrowing net interest margins and an increase in
noninterest expense associated with a computer conversion project and the
addition of personnel to administer new loans and loan participations. Net
income for the year ended December 31, 1996, was $180,000 or 12.4%, greater than
that realized in the year ended December 31, 1995.

         For the six months ended June 30, 1998, net income increased by 4.6%
over net income in the period ended June 30, 1997, growing from $791,000 to
$827,000.

INTEREST INCOME

         In the two prior fiscal years, interest income has increased as total
assets have grown. Interest income of $7,358,000 for the year ended December 31,
1997, represented a 6.2%, or $430,000, increase over interest income of
$6,928,000 for the year ended December 31, 1996. Interest income for 1996
represented an $892,000, or 14.8%, increase of interest income of $6,036,000 for
the year ended December 31, 1995.


         In the six months ended June 30, 1998, interest income reached
$3,720,000, an increase of $155,000, or 4.3%, over interest income of $3,565,000
for the six months ended June 30, 1997. The rate of increase was less than in
prior periods due to the decline in total assets.

NONINTEREST INCOME AND EXPENSE

         Noninterest income has been provided primarily by overdraft charges,
service charges on depository accounts, safety deposit box fees, and other
similar charges, and while not material in comparison to interest income,
noninterest income grew by 9.4% in the year ended December 31, 1997, 11.7% in
the year ended December 31, 1996, and 36.7% in the six months ended June 30,
1998, when compared to the six months ended June 30, 1997.


         Noninterest expense includes the costs of operations, including
overhead and added personnel expenses as employees are added to administer
additional loans and loan participations. Noninterest expense in the year ended
December 31, 1997, also included the costs of a computer conversion project and
totaled $1,606,000, an increase of $310,000, or 23.9%, over noninterest expense
of $1,296,000 in the year ended December 31, 1996. Noninterest expense in 1996
grew a nominal $7,000 over noninterest expense in the year ended December 31,
1995. For the six months ended June 30, 1998, noninterest expense increased by
$27,000 or 3.7% to $750,000 over the noninterest expense in the same period a
year earlier.

NET INTEREST INCOME

          Net interest income, the primary source of earnings for the Bank, is
the difference between interest income earned on loans and other earning assets,
and interest paid on deposits and other interest bearing liabilities. Earning
assets include loans, investment securities and federal funds sold. Interest
bearing liabilities include interest-bearing deposits (NOW accounts, MMDA,
savings and others), time deposits, federal funds purchased and securities sold
under agreements to repurchase.

         The following table sets forth the Bank's average balance of assets,
liabilities and stockholders' equity as well as the amount of interest income or
interest expense and the average rate for each category of interest earning
assets and interest bearing liabilities. Included in the average balances are
non-accruing loans. Loan fees are included in interest income. Average balances
are computed on a daily basis.

(1)  Includes non-interest bearing balances, cash and cash items. 
(2)  Loans, net of loan losses.
(3)  Net interest yield is net interest earnings divided by total
     interest-earning assets, with net interest earnings equal to the difference
     between total interest earned and total interest paid.


         Total average interest bearing liabilities and average interest earning
assets grew by 9.5% and 9.1%, respectively, in 1997 over 1996. The net interest
spread and net interest yield each declined slightly, primarily reflecting the
effects of the loans made in the more price-competitive Springfield market.

         The effect of changes in average balance and rate from the
corresponding prior period on interest income, interest expense and net interest
income for the year ended December 31, 1997 is set forth below. The effect of a
change in average balance has been determined by applying the average rate for
the earlier period to the change in the average balance for the later period, as
compared with the earlier period. The effect of a change in the average rate has
been determined by applying the average balance for the earlier period to the
change in the average rate for the later period, as compared with the earlier
period. The variances attributable to simultaneous balance and rate changes have
been allocated in proportion to the relationship of the dollar amount of change
in each category.

INVESTMENT SECURITIES PORTFOLIO ANALYSIS

         The Bank invests a portion of its available funds in short-term and
longer-term instruments, including federal funds sold and investment securities.
Investment securities include obligations of the U.S. Government or its
agencies, obligations of state and political subdivisions and debt securities.

         Federal funds sold are used primarily for daily cash management
purposes. The Bank's investment securities portfolio is utilized to
collateralize certain of the Bank's line of credit and public and fiduciary
deposits. It also provides liquidity through proceeds from scheduled maturities.
The majority of the Bank's investment securities carry fixed interest rates, and
at December 31, 1997 and June 30, 1998, the Bank's investment portfolio
reflected a net unrealized gain of approximately $187,000 and $150,000,
respectively.

         The following table presents the Bank's investments in certain
securities accounted for as held to maturity ("HTM") or as available for sale
("AFS") on the dates indicated.

</TABLE>


         Real Estate construction loans consist primarily of residential and
commercial construction loans for properties located in southwest Missouri.

         Real estate mortgage loans, including 1-4 family and multi-family
loans, are collateralized by residential properties that are principally located
in southwest Missouri.

         Real estate-non-farm, non-residential loans are secured by commercial
properties principally located in Springfield, Missouri.

         Sac River's commercial and industrial loans are primarily loans to
customers in the southwest Missouri trade area and are diversified from an
industry and customer standpoint, which helps to minimize risk. Consistent with
management's emphasis on relationship banking, most borrowing customers also
maintain deposit accounts and use other banking services. Management believes
the inherent risks of commercial and industrial loans to be relatively low,
given the diversity of the portfolio and collateral margins. Sac River holds
Small Business Administration guarantees of slightly more than half of the
amount of its commercial loans.

         The consumer loan portfolio consists of both secured and unsecured
loans to individuals for various personal reasons such as automobile financing,
home improvements, education and recreational purposes. New charge-offs of
consumer loans have been relatively low for the past several years. Management
believes the inherent risks associated with these loans to be relatively low and
that net charge-offs on these loans will continue to be below industry averages,
due to sufficient collateral margins and the diversity of the portfolio.

         The Bank's loan portfolio is varied, with no undue concentration in any
single industry, although most of the loans in the Bank's portfolio have been
made to borrowers in the southwest Missouri area.

RISK ELEMENTS OF LOAN PORTFOLIO

         Management reviews the Bank's loan portfolio on a regular basis for
problem loans. During the ordinary course of business, management becomes aware
of borrowers that may not be able to meet contractual requirements of loan
agreements. Such loans are placed on the Bank's watch list, which is reviewed by
the Bank's Board of Directors on a monthly basis. Management then determines the
need for additions to the allowance for loan loss. The Bank's allowance for loan
loss is determined as 50% of loans management considers doubtful, 10% of loans
on the watch list, and 1 1/2% of the remainder of the Bank's loan portfolio.
Those loans on which management does not expect to collect interest in the
normal course of business, or which are 90 days or more past due as to principal
or interest, are generally placed on nonaccrual status and management determines
the need for a partial or full charge-off of such loans. After a loan is placed
on nonaccrual status, interest income is recognized only on a cash

                                       91

basis so long as management is satisfied there is not impairment of the book
value of the loan. The loan is returned to accrual status only when the borrower
has brought all past due principal and interest payments current, and in the
opinion of management, the borrower has demonstrated the ability to make future
payments of principal and interest as scheduled.

PROVISION FOR LOAN LOSSES

         The provision for loan losses represents management's determination of
the amount necessary to be charged against the current period's earnings, in
order to maintain the allowance for loan losses at a level which is considered
adequate, in relation to the estimated risk inherent in the loan portfolio. The
Bank determines its allowance for loan loss as 50% of loans the management
considers doubtful, 10% of loans on the watch list and 1 1/2% of all other loans
in the Bank's portfolio. See "Financial Condition-Allowances for Loan Losses."

         The following table presents an analysis of the Bank's loss experience
for the periods indicated.

ALLOWANCE FOR LOAN LOSSES

          Management establishes the allowance for loan losses through a
provision for loan losses based on its evaluation of the risk inherent in its
loan portfolio and the general economy. This evaluation, which includes a review
of all loans on which full collectibility may not be reasonably assured,
considers among other matters, the estimated fair value of the underlying
collateral, economic conditions, historical loan loss experience, and other
factors that warrant recognition in providing for an adequate loan loss
allowance. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Bank's allowance for loan
losses and valuation of foreclosed assets held for sale. These agencies may
require the Bank to recognize additions to the allowance based on their
judgments about information available to them at the time of their examination.

         Management has established an allowance for loan losses which reduces
the total loans outstanding by an estimate of potential loan losses, plus an
excess margin for potential future uncertainties. Loans deemed uncollectible are
charged against and reduce the allowance. Sac River expenses its provisions for
loan losses against current income. The provision replenishes the allowance for
loan losses and maintains the allowance at acceptable levels based upon the
judgment of management. Sac River bases the allowance for loan losses upon
current economic conditions, risks in the loan portfolio, historical loan loss
experience and other factors that, in management's opinion, deserve current
recognition. See "Results of Operations-Provision for Loan Losses."

DEPOSITS

         The Bank's deposit base is its primary source of funds. The Bank offers
a broad range of deposit products, including noninterest demand deposits, NOW
accounts, savings deposits, individual retirement accounts and certificates of
deposit.

         At December 31, 1997, 6.9% of total deposits were in noninterest
bearing accounts, 32.2% in savings and interest bearing demand accounts and
60.9% in certificates of deposit.

         The following table presents the average balances of and the average
rate paid on certain categories of deposits for the periods indicated.

effects of increases in non-interest expenses associated with a computer
conversion project and increased personnel costs, growth in the Bank's size, and
increased competition.

SHORT-TERM BORROWINGS

         Short-term borrowings consist of securities sold under agreements to
repurchase. These amounted to $14,875,000 at December 31, 1997, and $8,751,000
at December 31, 1996. The average yield on

short-term borrowings was 5.38% and 5.68% during 1997 and 1996, respectively.
The majority of these instruments have terms ranging from one to 365 days. The
maximum amounts of short-term borrowings outstanding at any month end during
1997 and 1996 were $14,875,000 and $9,936,000. Information regarding the levels
of short-term borrowings for 1997 and 1996 are as follows:

         The average amount outstanding was computed from daily averages and the
average interest rates for the period were computed by dividing the respective
interest expense by the average balance outstanding. The increase in securities
sold under agreements to repurchase in 1997 resulted primarily from repurchase
agreements with Liberty Bank and another southwest Missouri bank.

LIQUIDITY AND CAPITAL RESOURCES

         Liquidity risk is managed by the Bank through the composition of its
assets and liabilities in an effort to meet efficiently the borrowing needs and
withdrawal requirements of its customers. Cash and cash equivalents include
cash, due from banks and federal funds sold. The primary sources of the Bank's
liquidity are cash and cash equivalents and investment securities with
short-term maturities. The Bank's primary method of asset/liability management
is the matching of the length of assets (loans) to the length of liabilities
(deposits). The Bank believes its process of asset/liability management allows
adequate reaction time for trends in the marketplace as they occur, minimizing
the negative impact of such trends on the net interest margin.

         Although the Bank has a relatively high volume of its loans and
certificates of deposit (CD's) that mature in one year or less, the Bank's CD's
have historically been a stable source of funds. Historically, a large majority
of the loans and certificates of deposit originated by the Bank have been
renewed at maturity. In addition, the Bank has been and continues to be
competitive on interest rates for both loans and CD's.

          If a significant portion of CD's were not replaced at maturity, the
Bank could utilize borrowings available to it from the Federal Home Loan Bank.
It could also raise CD rates to stay competitive in the marketplace. In
addition, the Bank could sell available-for-sale investment securities to the
extent they


                                       97



                                       
<PAGE>   108

are not pledged for public funds. At December 31, 1997, the Bank had $23.3
million of available-for-sale securities in its portfolio.

         If a significant amount of loans that mature over the next year were
not renewed, the Bank could participate in loans originated by other financial
institutions as it has done in the past, it could increase its investments in
securities, or it could lower interest rates charged on loans to remain
competitive in its marketplace.

         Cash flows from operating activities for the periods covered by the
Statements of Cash Flows relate primarily to net income, adjusted for changes in
accrued interest receivable, credits and other liabilities, the provision for
loan losses, depreciation and the amortization of discounts (premiums) on
investments, all of which are non-cash or non-operating adjustments to operating
cash flows. Operating activities provided cash flows of $941,000, $2.0 million,
and $1.3 million for the period ended June 30, 1998 and the years ended December
31, 1997 and 1996, respectively.

      During the six months ended June 30, 1998, investing activities
provided cash of $11.7 million primarily due to the maturity of $12.5 million of
available-for-sale securities. For the years ended December 31, 1997 and 1996,
investing activities used cash of $10.0 million and $12.2 million, respectively,
due to the purchase of available-for-sale and held-to-maturity securities in
each period, as well as the net originations of loans.

         Cash flows used in financing activities was $12.5 million during the
six months ended June 30, 1998, due primarily to a decrease in securities sold
under agreement to repurchase of $13.7 million. This was partially offset by
$2.0 million in loan proceeds taken as a Federal Home Loan Bank advance.
Financing activities increased during the years ended December 31, 1997 and 1996
due to increases in deposits after interest credited and an increase in
securities sold under agreement to repurchase in both years. In all periods, the
bank paid dividends of $800,000. Cash provided by financing activities was $8.9
million and $5.9 million for the years ended December 31, 1997 and 1996.

YEAR 2000

         Like all banks, Sac River is heavily reliant upon computer hardware and
software, including data processing services to operate and maintain customer
accounts, loan accounts, investments, ATM systems, and other core functions.
Other non-core functions also use software and embedded microprocessor
technology. Both core and non-core functions are susceptible to the "Year 2000"
problem, which means that software and microprocessors will report January 1,
2000, and subsequent dates as January 1, 1900, or other incorrect twentieth
century dates. This incorrect dating could make it very difficult for Sac River
to conduct business electronically.


                                       98



                                       
<PAGE>   109

         Third party suppliers provide Sac River with many of these electronic
services. (Many of Sac River's suppliers provide the same services to Liberty,
and as a result Sac River and Liberty have developed similar programs for
dealing with Year 2000 issues.) Sac River also owns or leases other information
technology, including equipment with embedded technology that control various
systems within the bank.

         In 1997, Sac River formed a committee of employees to assess the bank's
Year 2000 issues and implement remedies. The committee meets regularly and has
undertaken the following activities, among others:

         -        Identifying software and equipment that may not be Year 2000 
                  compliant.
         -        Identifying borrowers who may face Year 2000 issues and 
                  assessing the seriousness of the problem.
         -        Creating a database identifying each system, its compliance
                  status, its level of risk, estimated cost to comply, estimated
                  date to comply, and last test date.
         -        Seeking certificates of compliance from vendors.
         -        Arranging test schedules with vendors and conducting tests of 
                  owned and leased equipment.
         -        Contacting local utilities to determining their ability to
                  provide electricity, water, and gas service after December 31,
                  1999.
         -        Installing compliant versions of core technologies provided 
                  by the bank's vendors.
         -        Preparing a liquidity plan.
         -        Preparing a contingency plan.
         -        Ordering or installing equipment with compliant embedded 
                  technology.

         As of August 1998, Sac River's core data processing system and teller
software were Year 2000 compliant and had been extensively tested by their
vendors. Sac River intends, however, to conduct its own tests of these systems.
Similarly, the bank's software for communication with the Federal Reserve was
compliant following upgrades. Tests of the bank's ATM software will occur in
February 1999. All of the bank's personal computers are compliant, as is the
bank's loan processing software.

         Certain less significant systems remain to be tested, including the
payroll, processing software, certain credit services software, and the
telephone switch software. Sac River anticipates that all remaining software and
technology will be compliant and fully tested by June 30, 1999.

         Third party vendors have borne most of the cost of making Sac River
Year 2000 compliant. Costs incurred by Sac River have largely been in the form
of the compensation and benefits provided existing bank employees who have
conducted the compliance activities. Sac River hired no consultants or new
employees to achieve Year 2000 compliance, and it has not allocated employee
compensation and benefit expense to the project. Sac River has not incurred any
non-employee 


                                       99


                                      
<PAGE>   110
expenses to date in implementing its compliance program and expects that its
total non-employee costs will be $3,000 or less through January 1, 2000.

          While Sac River believes that its systems and technology will be
compliant on January 1, 2000, and thereafter, it faces an unquantifiable risk
that third parties such as customers will encounter Year 2000 problems that
cause them to reduce their use of bank services, default on loans, or reduce
levels of future borrowings. There is also a risk that other financial
organizations with which Sac River maintains relations could experience Year
2000 issues that would adversely affect Sac River. Finally, if other service
providers, such as public utilities or telephone companies, are not Year 2000
compliant, the bank could experience service interruptions that would make the
conduct of business difficult.

          Sac River has developed a contingency plan to address some of these
uncertainties. For example, the bank will have a backup generator available if
its electric utility cannot deliver power. It also plans to have in place a
cellular based modern communication system to maintain communication with its
data service providers in the event that landline communications are disrupted.
Immediately before the change of the century, electronic trial balances with
extended information will be downloaded for import into local database files.
There will also be a complete backup of all files before the century change, and
critical information will be printed in hardcopy. The bank will take other steps
to assure both liquidity and security.

          In summary, Sac River believes that it has completed about 90% of the
actions necessary to achieve Year 2000 compliance for its core systems and 50%
or more of the work necessary to achieve overall compliance. Sac River believes
that it will complete the rest of the program and achieve compliance before the
century date change. There remains, however, the possibility that problems
encountered by third parties could adversely affect the bank.


INTEREST RATE SENSITIVITY

         Asset and liability management encompasses both interest rate risk and
liquidity management. Sac River's net interest margin can be vulnerable to wide
fluctuations arising from a change in the general level of interest rates which
may affect the yield on interest earning assets differently than the cost of the
interest bearing liabilities. Sac River monitors its asset and liability mix in
an effort to maintain a consistent earnings performance through control of
interest rate risk.

         Below is the "Static gap" table for Sac River as of December 31, 1997.
This is just one of several tools which may be used to measure and manage
interest rate sensitivity. Earning assets and interest bearing liabilities are
presented below within selected time intervals based on their repricing and
maturity characteristics. In this view, the sensitivity position is perfectly
matched when an equal amount of assets and liabilities reprice during any given
period. Excess assets or liabilities repricing in a given time period result in
the "Interest Sensitivity Gap" shown at the bottom of the table. A positive gap
indicates more assets than liabilities will reprice in that time period, while a
negative gap indicates more liabilities than assets will reprice.

         The table indicates Sac River is liability sensitive in the three
months or less period and is asset sensitive in all other periods. This means
that during the three months or less period, interest bearing 



                                      100


                                       
<PAGE>   111

liabilities are repricing faster than earning assets, thereby improving net
interest income when rates are declining and reducing net interest income when
rates are rising. While the "static gap" is a widely used measure of interest
sensitivity, it is not, in management's opinion, the only indicator of Sac
River's sensitivity position.

         The following table indicates as of December 31, 1997, the time period
in which interest earning assets and interest bearing liabilities are scheduled
to mature or reprice in accordance with their contractual terms.

         An interest sensitivity table is not a complete picture of the possible
effect of interest rate changes on net interest income. First, changes in the
general level of interest rates will not affect all categories of assets and
liabilities equally or simultaneously. Second, the table represents a one-day
position; variations 



                                      101

occur daily as the Company adjusts its interest sensitivity throughout the year.
Third, the repricing distribution of interest sensitive assets may not be
indicative of the liquidity of those assets. Finally, since this table is based
on contractual maturities, it does not include required principal payments or
estimates of early principal payments on residential mortgages, installment
loans and investment securities.

CAPITAL ADEQUACY

         Stockholders' equity represented 12.3% of total assets at June 30,
1998. Risk-based capital and leverage ratios of the Bank exceeded minimum
requirements of regulatory banking authorities. See note 10 to Sac River's
financial statements for the years ended December 31, 1997 and 1996 for
additional information about Sac River's capitalization and regulatory capital
requirements.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         The FASB recently adopted Statement of Financial Accounting Standards
("SFAS") 128, "Earnings Per Share." This statement replaces the presentation of
primary earnings per share with a presentation of basic earnings per share. The
statement also requires dual presentation of basic and diluted earnings per
shares by entities with complex capital structures and requires a reconciliation
of the numerators and denominators between the two calculations. SFAS 128 is
effective for financial statements issued for periods ending after December 15,
1997, including interim periods. Management has presented earnings per share in
accordance with SFAS 128 in its December 31, 1997 financial statements. The
adoption of SFAS 128 did not have a material impact on the Bank's financial
statements.

         The FASB recently adopted SFAS 129, "Disclosure of Information about
Capital Structure." This statement establishes standards for disclosing
information about capital structure, including pertinent rights and privileges
of various securities outstanding. SFAS 129 is effective for financial
statements issued for periods ending after December 15, 1997. The adoption of
SFAS 129 did not have a material impact on the Bank's financial statements.

         The FASB recently adopted SFAS 130, "Reporting Comprehensive Income."
This statement establishes standards for reporting and display of comprehensive
income and its components, in a full set of financial statements. It does not
address issues of recognition or measurement. SFAS is effective for fiscal years
beginning after December 15, 1997. The adoption of SFAS 130 did not have a
material impact on the Bank's financial statements.

         The FASB recently adopted SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information." This statement establishes standards for
the way that public business enterprises report information about operating
segments in both annual financial statements and interim financial reports
issued to shareholders. The statement also establishes standards for related
disclosures about products and services, geographic areas and major customers.
SFAS 131 is effective for financial statements issued for periods beginning
after December 15, 1997. The adoption of SFAS 131 is not expected to have a
material impact on the Bank's financial statements.

         The FASB recently adopted SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments and for hedging activities. SFAS
133 is effective for all fiscal quarters of fiscal years beginning after June
15, 1999. Management has not yet determined the impact, if any, of SFAS 133 on
the Bank's financial statements.

EFFECT OF ECONOMIC CONDITIONS

          The Bank's financial statements have been prepared in accordance with
generally accepted accounting principles, which required the measurement of
financial position and operating results in terms of historical dollars without
consideration for changes in the relative purchasing power of money over time
due to inflation. The assets and liabilities of the Bank are primarily monetary
and interest rates have a greater impact on the Bank's performance than does the
effect of inflation. The local economy of the Southwest Missouri area has
experienced growth over the last several years. The area has a good mix of
retail, agricultural related and industrial business.


                         ADJOURNMENT OF SPECIAL MEETING

         Under certain circumstances, Sac River's management may determine at
the time of the Special Meeting that it is in the best interest of Sac River and
its shareholders to adjourn the Special Meeting to a later date. For example, in
the event that the number of shares present, in person or by proxy, at the
Special Meeting is insufficient to constitute a quorum or to approve the Merger
Agreement, Sac River might decide to adjourn the Special Meeting to permit
further solicitation of proxies. Sac River might also decide to adjourn the
Special Meeting in the event that the parties determine that events occurring
subsequent to the date of this Proxy Statement require Sac River to furnish
additional proxy soliciting information to the shareholders and to give the
shareholders an opportunity to assimilate such information. If the Special
Meeting is adjourned, no further notice of the time and place of the adjourned
meeting is required to be given to Sac River shareholders other than an
announcement of such time and place at the Special Meeting. The vote of the
holders of a majority of shares of Sac River Common Stock present at the Special
Meeting in person or by proxy, whether or not a quorum is present, is required
to approve a proposal for adjournment at the Special Meeting.

         Sac River's management also may determine at the time of the Special
Meeting that it is in the best interest of Sac River and its shareholders to
adjourn the Special Meeting for up to 90 days if, at the time of the Special
Meeting, the holders of a sufficient number of Sac River Common Stock have
indicated that they intend to elect under the Merger Agreement to receive the
Optional Per Share Cash Amount rather than the right to receive shares of
Bancshares Common Stock, and, as a result, the total cash payable by Bancshares
as the Optional Per Share Cash Amount to all shareholders of Sac River would
exceed $2,800,000. During the adjournment, representatives of Sac River would
ascertain whether a sufficient number of shareholders would change their
election so that the Option Per Share Cash Amount would not exceed $2,800,000.
         SAC RIVER SHAREHOLDERS WILL NOT HAVE A VOTE ON ANY OF THE ADJOURNMENTS
DESCRIBED IN THIS SECTION.
         The board of directors of Sac River recommends that shareholders vote
FOR the proposal to adjourn the Special Meeting so that such proxies may be
voted in favor of such adjournment under such circumstances.

                                 LEGAL OPINIONS

         The legality of the Bancshares Common Stock to be issued pursuant to
the Merger will be passed upon for Bancshares by Husch & Eppenberger, LLC. Husch
& Eppenberger has also delivered an opinion

                         Independent Accountants' Report


Board of Directors
Liberty Bancshares, Inc.
    and Subsidiary
Springfield, Missouri


    We have audited the accompanying consolidated balance sheets of LIBERTY
BANCSHARES, INC. AND SUBSIDIARY as of December 31, 1997 and 1996, and the
related consolidated statements of income, changes in stockholders' equity and
cash flows for the years ended December 31, 1997 and 1996, and for the 65-day
period ended December 31, 1995. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of LIBERTY
BANCSHARES, INC. AND SUBSIDIARY as of December 31, 1997 and 1996, and the
results of its operations and its cash flows for each of the two years ended
December 31, 1997 and 1996, and for the 65-day period ended December 31, 1995,
in conformity with generally accepted accounting principles.

NOTE 1:      NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT
             ACCOUNTING POLICIES

NATURE OF OPERATIONS

   Liberty Bancshares, Inc. (the Company) operates as a one-bank holding
company. Liberty Bank (the Bank) opened for business on October 27, 1995, and is
primarily engaged in providing a full range of banking and mortgage services to
individual and corporate customers in southwest Missouri. The Bank is subject to
competition from other financial institutions. The Bank also is subject to the
regulation of certain federal and state agencies and undergoes periodic
examinations by those regulatory authorities.

   The consolidated financial statements as of June 30, 1998, and for the
periods ended June 30, 1998 and 1997, are unaudited, but in the opinion of
management, include all adjustments, consisting only of normal, recurring items,
necessary for fair presentation.

USE OF ESTIMATES

   The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

   Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for loan losses and the valuation
of real estate acquired in connection with foreclosures or in satisfaction of
loans. In connection with the determination of the allowance for loan losses and
the valuation of foreclosed assets held for sale, management obtains independent
appraisals for significant properties.

   Management believes that the allowances for losses on loans are adequate.
While management uses available information to recognize losses on loans,
changes in economic conditions may necessitate revision of these estimates in
future years. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Bank's allowances for losses
on loans. Such agencies may require the Bank to recognize additional losses
based on their judgments of information available to them at the time of their
examination.

PRINCIPLES OF CONSOLIDATION

   The consolidated financial statements include the accounts of Liberty
Bancshares, Inc. and its 100%-owned subsidiary, Liberty Bank. Significant
intercompany accounts and transactions have been eliminated in consolidation.

CASH EQUIVALENTS

   The Bank considers all liquid investments with original maturities of three
months or less to be cash equivalents. At December 31, 1997 and 1996, cash
equivalents consisted of federal funds sold and securities purchased under
agreements to resell.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                     YEARS ENDED DECEMBER 31, 1997 AND 1996
                       AND 65 DAYS ENDED DECEMBER 31, 1995

INVESTMENTS IN DEBT AND EQUITY SECURITIES

   Available-for-sale securities, which include any security for which the Bank
has no immediate plan to sell but which may be sold in the future, are carried
at fair value. Realized gains and losses, based on specifically identified
amortized cost of the specific security, are included in other income.
Unrealized gains and losses are recorded, net of related income tax effects, in
stockholders' equity. Premiums and discounts are amortized and accreted,
respectively, to interest income using the level-yield method over the period to
maturity. The Bank has classified all of its investment securities as
available-for-sale.

   Interest and dividends on investments in debt and equity securities are
included in income when earned.

MORTGAGE LOANS HELD FOR SALE

   Mortgage loans held for sale are carried at the lower of cost or fair value,
determined using an aggregate basis. Write-downs to fair value are recognized as
a charge to earnings at the time the decline in value occurs. Forward
commitments to sell mortgage loans are acquired to reduce market risk on
mortgage loans in the process of origination and mortgage loans held for sale.
Amounts paid to investors to obtain forward commitments are deferred until such
time as the related loans are sold. The fair values of the forward commitments
are not recognized in the financial statements. Gains and losses resulting from
sales of mortgage loans are recognized when the respective loans are sold to
investors. Gains and losses are determined by the difference between the selling
price and the carrying amount of the loans sold, net of discounts collected or
paid, commitment fees paid and considering a normal servicing rate. Fees
received from borrowers to guarantee the funding of mortgage loans held for sale
and fees paid to investors to ensure the ultimate sale of such mortgage loans
are recognized as income or expense when the loans are sold or when it becomes
evident that the commitment will not be used.

LOANS

   Loans that management has the intent and ability to hold for the foreseeable
future or until maturity or pay-offs are reported at their outstanding principal
adjusted for any charge-offs, the allowance for loan losses and any deferred
fees or costs on originated loans and unamortized premiums or discounts on
purchased loans.

ALLOWANCE FOR LOAN LOSSES

   The allowance for loan losses is increased by provisions charged to expense
and reduced by loans charged off, net of recoveries. The allowance is maintained
at a level considered adequate to provide for potential loan losses, based on
management's evaluation of the loan portfolio, as well as on prevailing and
anticipated economic conditions and historical losses by loan category. General
allowances have been established, based upon the aforementioned factors, and
allocated to the individual loan categories. Allowances are accrued on specific
loans evaluated for impairment for which the basis of each loan, including
accrued interest, exceeds the discounted amount of expected future collections
of interest and principal or, alternatively, the fair value of loan collateral.

   A loan is considered impaired when it is probable that the Bank will not
receive all amounts due according to the contractual terms of the loan. This
includes loans that are delinquent 90 days or more (nonaccrual loans) and
certain other loans identified by management. Accrual of interest is
discontinued, and interest accrued and unpaid is removed, at the time such
amounts are delinquent 90 days. Interest is recognized for nonaccrual loans only
upon receipt, and only after all principal amounts are current according to the
terms of the contract.

PREMISES AND EQUIPMENT

   Depreciable assets are stated at cost less accumulated depreciation.
Depreciation is charged to expense using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are capitalized and
amortized using the straight-line method over the terms of the respective leases
or the estimated useful lives of the improvements, whichever is shorter.

FEE INCOME

   Loan origination fees, net of direct origination costs, are recognized as
income over the term of the loans.

EARNINGS PER SHARE

   Effective December 15, 1997, the Company adopted the provisions of SFAS No.
128, Earnings Per Share (EPS), which requires dual presentation of basic and
diluted EPS for all entities with complex capital structures. Basic earnings per
share is computed based on the weighted average number of shares outstanding
during each year. Diluted earnings per share is computed using the weighted
average common shares and all potential dilutive common shares outstanding
during the period.

   The computation of per share earnings is as follows:

effective in the form of a dividend on the outstanding common stock of the
Company. Historical per share disclosures have been updated where applicable to

INCOME TAXES

   Deferred tax liabilities and assets are recognized for the tax effect of
differences between the financial statement and tax bases of assets and
liabilities. A valuation allowance is established to reduce deferred tax assets
if it is more likely than not that a deferred tax asset will not be realized.

   The Bank enters into purchases of securities under agreements to resell. The
amounts advanced under these agreements represent short-term loans and are
reflected as a receivable in the balance sheet. The securities underlying the
agreements are book-entry securities. During the period, the securities were
delivered by appropriate entry into a third-party custodian's account designated
by the Bank under a written custodial agreement that explicitly recognizes the
Bank's interest in the securities. These agreements mature on demand. At
December 31, 1997 and 1996, all agreements to resell securities purchased were
with one correspondent bank. Securities purchased under agreements to resell
averaged $8,010,000 and $5,327,000 during 1997 and 1996, and the maximum amount
outstanding at any month end during 1997 and 1996 was $12,520,000 and

NOTE 10: REGULATORY MATTERS

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

   Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined) and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1997, that the Bank
meets all capital adequacy requirements to which it is subject.

   As of December 31, 1997, the most recent notification from the FDIC
categorized the Bank as well capitalized under the regulatory framework for
prompt corrective action. To be categorized as well capitalized the Bank must
maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios
as set forth in the table. There are no conditions or events since that
notification that management believes have changed the Bank's category.

   The Bank's actual capital amounts and ratios are also presented in the table.

   Additionally, the Bank is subject to certain restrictions on the amount of
dividends that it may pay without prior regulatory approval. Currently, the Bank
may not pay dividends which would reduce Tier I Capital below 10.0%.

   Subsequent to December 31, 1997, the Company's Board of Directors voted to
inject additional capital of $750,400 into the Bank during 1998.


NOTE 11:  STOCK OPTION PLAN

   Under the Company's stock option plan, 15,000 shares of common stock were
reserved for issuance upon exercise of options granted to officers and key
employees. The plan basically provides that the option price will be no less
than fair market value of the stock at the date of the grant. Options granted
are exercisable immediately after the date of grant and expire October 27, 2006.

   A summary of the status of the plan at December 31, 1997 and 1996, and
changes during the periods then ended is presented below:

    The Company applies APB Opinion 25 and related Interpretations in accounting
for the plan, and no compensation cost has been recognized. Had compensation
cost for the Company's Plan been determined based on the fair value at the grant
dates using Statement of Financial Accounting Standards No. 123, the Company's
net income would have decreased by $13,600 and $14,600 and earnings per share
would have decreased by $.03 and $.04 for 1997 and 1996, respectively. The
effects of applying this statement for either recognizing compensation cost or
providing pro forma disclosures are not likely to be representative of the
effects on reported net income for future years because options vest over
several years and additional awards generally are made each year.

NOTE 12:      TRANSACTIONS WITH RELATED PARTIES

   At December 31, 1997 and 1996, the Bank had loans outstanding to employees,
executive officers, directors and companies in which the bank's executive
officers or directors were principal owners, in the amount of $11,862,000 and
$3,042,000, respectively.

   A reconciliation of the activity in these loans for the year ended December

   In management's opinion, such loans and other extensions of credit and
deposits were made in the ordinary course of business and were made on
substantially the same terms (including interest rates and collateral) as those
prevailing at the time for comparable transactions with other persons. Further,
in management's opinion, these loans did not involve more than normal risk of
collectibility or present other unfavorable features.

NOTE 14:      SIGNIFICANT ESTIMATES AND CONCENTRATIONS

   Generally accepted accounting principles require disclosure of certain
significant estimates and current vulnerabilities due to certain concentrations.
Estimates related to the allowance for loan losses are reflected in the footnote
regarding loans. Current vulnerabilities due to certain concentrations of credit
risk are discussed in the footnote on commitments and credit risk.


NOTE 15:      COMMITMENTS AND CREDIT RISK

   Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee. Since a portion of the commitments may expire without
being drawn upon, the total commitment amounts do not necessarily represent
future cash requirements. Each customer's credit worthiness is evaluated on a
case-by-case basis. The amount of collateral obtained, if deemed necessary, is
based on management's credit evaluation of the counterparty. Collateral held
varies, but may include accounts receivable, inventory, property, plant and
equipment, commercial real estate and residential real estate.

   At December 31, 1997 and 1996, the Bank had outstanding commitments to
originate loans aggregating approximately $3,927,000 and $4,110,000,
respectively. The commitments extended over varying periods of time with the
majority being disbursed within a one-year period.

   Letters of credit are conditional commitments issued by the Bank to guarantee
the performance of a customer to a third party. Those guarantees are primarily
issued to support public and private borrowing arrangements, including
commercial paper, bond financing and similar transactions. The credit risk
involved in issuing letters of credit is essentially the same as that involved
in extending loans to customers.

   The Bank had total outstanding letters of credit amounting to $218,000 and
$846,000 at December 31, 1997 and 1996, with terms ranging from 30 days to 24
months.

   Lines of credit are agreements to lend to a customer as long as there is no
violation of any condition established in the contract. Lines of credit
generally have fixed expiration dates. Since a portion of the line may expire
without being drawn upon, the total unused lines do not necessarily represent
future cash requirements. Each customer's credit worthiness is evaluated on a
case-by-case basis. The amount of collateral obtained, if deemed necessary, is
based on management's credit evaluation of the counterparty. Collateral held
varies but may include accounts receivable, inventory, property, plant and
equipment, commercial real estate and residential real estate. Management uses
the same credit policies in granting lines of credit as it does for on-balance
sheet instruments.

   At December 31, 1997 and 1996, the Bank had granted unused lines of credit to
borrowers aggregating approximately $2,927,000 and $797,000, respectively, for
commercial lines and open-end consumer lines.


NOTE 16: 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:

CASH AND CASH EQUIVALENTS

   For these short-term instruments, the carrying amount approximates fair
value.

INVESTMENT SECURITIES

   Fair values for investment securities equal quoted market prices, if
available. If quoted market prices are not available, fair values are estimated
based on quoted market prices of similar securities.

LOANS

   The fair value of loans is estimated by discounting the future cash flows
using the current rates at which similar loans would be made to borrowers with
similar credit ratings and for the same remaining maturities. Loans with similar
characteristics were aggregated for purposes of the calculations. The carrying
amount of accrued interest receivable approximates its fair value.

DEPOSITS

   The fair value of demand deposits, savings accounts, NOW accounts and certain
money market deposits is the amount payable on demand at the reporting date
(i.e., their carrying amount). The fair value of fixed-maturity time deposits is
estimated using a discounted cash flow calculation that applies the rates
currently offered for deposits of similar remaining maturities. The carrying
amount of accrued interest payable approximates its fair value.

                       AND 65 DAYS ENDED DECEMBER 31, 1995

SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE

   For these short-term instruments, the carrying amount is a reasonable
estimate of fair value.

NOTE PAYABLE

   Rates currently available to the Bank for debt with similar terms and
remaining maturities are used to estimate fair value of the existing note
payable.

LETTERS OF CREDIT AND LINES OF CREDIT

   The fair value of letters of credit and lines of credit is based on fees
currently charged for similar agreements or on the estimated cost to terminate
or otherwise settle the obligations with the counterparties at the reporting
date.

   The following table presents estimated fair values of the Company's financial
instruments. The fair values of certain of these instruments were calculated by
discounting expected cash flows, which method involves significant judgments by
management and uncertainties. Fair value is the estimated amount at which
financial assets or liabilities could be exchanged in a current transaction
between willing parties, other than in a forced or liquidation sale. Because no
market exists for certain of these financial instruments and because management
does not intend to sell these financial instruments, the Company does not know
whether the fair values shown below represent values at which the respective
financial instruments could be sold individually or in the aggregate.

                         Independent Accountants' Report

Board of Directors
Sac River Valley Bank
Springfield, Missouri


    We have audited the accompanying balance sheets of SAC RIVER VALLEY BANK as
of December 31, 1997 and 1996, and the related statements of income, changes in
stockholders' equity and cash flows for each of the years then ended. These
financial statements are the responsibility of the Bank'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 financial position of SAC RIVER VALLEY BANK as of
December 31, 1997 and 1996, and the results of its operations and its cash flows
for each of the years then ended in conformity with generally accepted
accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

                     YEARS ENDED DECEMBER 31, 1997 AND 1996


NOTE 1:     NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT
            ACCOUNTING POLICIES

NATURE OF OPERATIONS

   Sac River Valley Bank is primarily engaged in providing a full range of
banking and mortgage services to individual and corporate customers in southwest
Missouri. The Bank is subject to competition from other financial institutions.
The Bank also is subject to the regulation of certain federal and state agencies
and undergoes periodic examinations by those regulatory authorities.

   The consolidated financial statements as of June 30, 1998, and for the
periods ended June 30, 1998 and 1997, are unaudited, but in the opinion of
management, include all adjustments, consisting only of normal, recurring items,
necessary for fair presentation.

USE OF ESTIMATES

   The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

   Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for loan losses and the valuation
of real estate acquired in connection with foreclosures or in satisfaction of
loans. In connection with the determination of the allowance for loan losses and
the valuation of foreclosed assets held for sale, management obtains independent
appraisals for significant properties.

   Management believes that the allowances for losses on loans and the valuation
of foreclosed assets held for sale are adequate. While management uses available
information to recognize losses on loans and foreclosed assets held for sale,
changes in economic conditions may necessitate revision of these estimates in
future years. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Bank's allowances for losses
on loans and valuation of foreclosed assets held for sale. Such agencies may
require the Bank to recognize additional losses based on their judgments of
information available to them at the time of their examination.

CASH EQUIVALENTS

   The Bank considers all liquid investments with original maturities of three
months or less to be cash equivalents. At December 31, 1997 and 1996, cash
equivalents consisted of federal funds sold and securities purchased under
agreements to resell.

INVESTMENTS IN DEBT SECURITIES

   Available-for-sale securities, which include any security for which the Bank
has no immediate plan to sell but which may be sold in the future, are carried
at fair value. Realized gains and losses, based on specifically identified
amortized cost of the specific security, are included in other income.
Unrealized gains and losses are recorded, net of related income tax effects, in
stockholders' equity. Premiums and discounts are amortized and accreted,
respectively, to interest income using the level-yield method over the period to
maturity.

                                      SF-8

                          NOTES TO FINANCIAL STATEMENTS

                     YEARS ENDED DECEMBER 31, 1997 AND 1996


   Held-to-maturity securities, which include any security for which the Bank
has the positive intent and ability to hold until maturity, are carried at
historical cost adjusted for amortization of premiums and accretion of
discounts. Premiums and discounts are amortized and accreted, respectively, to
interest income using the level-yield method over the period to maturity.

   Interest and dividends on investments in debt and equity securities are
included in income when earned.

LOANS HELD FOR SALE

   Loans held for sale are carried at the lower of cost or fair value,
determined using an aggregate basis. Write-downs to fair value are recognized as
a charge to earnings at the time the decline in value occurs. Gains and losses
resulting from sales of loans are recognized when the respective loans are sold
to investors. Gains and losses are determined by the difference between the
selling price and the carrying amount of the loans sold, net of discounts
collected or paid and considering a normal servicing rate. Fees received from
borrowers to guarantee the funding of loans held for sale and fees paid to
investors to ensure the ultimate sale of such loans are recognized as income or
expense when the loans are sold or when it becomes evident that the commitment
will not be used.

LOANS

   Loans that management has the intent and ability to hold for the foreseeable
future or until maturity or pay-off are reported at their outstanding principal
adjusted for any charge-offs, the allowance for loan losses, and any deferred
fees or costs on originated loans and unamortized premiums or discounts on
purchased loans.

ALLOWANCE FOR LOAN LOSSES

   The allowance for loan losses is increased by provisions charged to expense
and reduced by loans charged off, net of recoveries. The allowance is maintained
at a level considered adequate to provide for potential loan losses, based on
management's evaluation of the loan portfolio, as well as on prevailing and
anticipated economic conditions and historical losses by loan category. General
allowances have been established, based upon the aforementioned factors and
allocated to the individual loan categories. Allowances are accrued on specific
loans evaluated for impairment for which the basis of each loan, including
accrued interest, exceeds the discounted amount of expected future collections
of interest and principal or, alternatively, the fair value of loan collateral.

   A loan is considered impaired when it is probable that the Bank will not
receive all amounts due according to the contractual terms of the loan. This
includes loans that are delinquent 90 days or more (nonaccrual loans) and
certain other loans identified by management. Accrual of interest is
discontinued and interest accrued and unpaid is removed at the time such amounts
are delinquent 90 days. Interest is recognized for nonaccrual loans only upon
receipt, and only after all principal amounts are current according to the terms
of the contract.

PREMISES AND EQUIPMENT

   Depreciable assets are stated at cost less accumulated depreciation.
Depreciation is charged to expense using straight-line and accelerated methods
over the estimated useful lives of the assets.

                     YEARS ENDED DECEMBER 31, 1997 AND 1996


FORECLOSED ASSETS HELD FOR SALE

   Assets acquired by foreclosure or in settlement of debt and held for sale are
valued at estimated fair value as of the date of foreclosure, and a related
valuation allowance is provided for estimated costs to sell the assets.
Management evaluates the value of foreclosed assets held for sale periodically
and increases the valuation allowance for any subsequent declines in fair value.
Increases in the valuation allowance and gains/losses on sales of foreclosed
assets are included in noninterest expense.

INCOME TAXES

   Deferred tax liabilities and assets are the tax effect of differences between
the financial statement and tax bases of assets and liabilities. A valuation
allowance is established to reduce deferred tax assets if it is more likely than
not that a deferred tax asset will not be realized.

ADOPTION OF NEW ACCOUNTING STANDARD

   During the period ended June 30, 1998, the Bank adopted the provisions of
Statement of Financial Accounting Standard No. 130, "Reporting Comprehensive
Income" by reclassification of all prior periods presented.


NOTE 2:     INVESTMENTS IN DEBT SECURITIES

   The amortized cost and approximate fair value of available-for-sale
securities are as follows:

NOTE 3:     SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL

   The Bank enters into purchases of securities under agreements to resell. The
amounts advanced under these agreements represent short-term loans and are
reflected as a receivable in the balance sheet. The securities underlying the
agreements are book-entry securities. During the period, the securities were
delivered by appropriate entry into a third-party custodian's account designated
by the Bank under a written custodial agreement that explicitly recognizes the
Bank's interest in the securities. These agreements have a weighted average
remaining maturity of three months. At December 31, 1997 and 1996, these
agreements to resell securities purchased were all outstanding with one entity.
The Bank's policy requires that all securities purchased under agreements to
resell be fully collateralized.

NOTE 10: REGULATORY MATTERS

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

                     YEARS ENDED DECEMBER 31, 1997 AND 1996

   Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined) and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1997, that the Bank
meets all capital adequacy requirements to which it is subject.

   As of December 31, 1997, the most recent notification from the FDIC
categorized the Bank as well capitalized under the regulatory framework for
prompt corrective action. To be categorized as well capitalized the Bank must
maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios
as set forth in the table. There are no conditions or events since that
notification that management believes have changed the Bank's category.

   The Bank's actual capital amounts and ratios are also presented in the table.

NOTE 11:    TRANSACTIONS WITH RELATED PARTIES

   At December 31, 1997 and 1996, the Bank had loans outstanding to officers,
directors and employees and companies in which the bank's executive officers or
directors were principal owners, in the amount of $624,000 and $562,000,
respectively.

   A reconciliation of the activity in these loans for the year ended December
31, 1997, is as follows:

             Balance, beginning of year                $      562,000
             New loans                                        300,000
             Repayments                                      (238,000)

             Balance, end of year                      $      624,000
                                                       ==============

   In management's opinion, such loans and other extensions of credit and
deposits were made in the ordinary course of business and were made on
substantially the same terms (including interest rates and collateral) as those
prevailing at the time for comparable transactions with other persons. Further,
in management's opinion, these loans did not involve more than normal risk of
collectibility or present other unfavorable features.

   Effective June 1996, the Bank entered into a loan servicing agreement with a
company that was controlled by one of the executive officers of the Bank. The
agreement called for the outside company to service certain of the Bank's
existing loan portfolio for a fee. Expense recognized by the Bank relating to
this agreement was $161,513 and $40,770 for 1997 and 1996, respectively.
Included in the 1997 expense was a payment of $66,000 made to terminate the
contract effective December 31, 1997.


NOTE 12:    EMPLOYEE BENEFIT PLANS

   The Bank has a defined contribution pension plan covering substantially all
employees. Employees may contribute up to $9,500 of their compensation with the
Bank matching a discretionary amount determined annually by the Board of
Directors up to the first 6% of the employee's compensation. Employer
contributions charged to expense for 1997 and 1996 were $11,191 and $9,174,
respectively.

   The Bank has in place an Employee Stock Ownership Plan (ESOP) for full-time
employees age 21 years or older who have at least one year of credited service.
Annual contributions to the ESOP are discretionary and are determined annually
by the Bank's Board of Directors. Contributions are credited to participants'
individual accounts based proportionally on each participant's compensation for
the plan year to total compensation of all participants in that plan year.
Benefits become 100% vested after seven years of service. Forfeitures are
reallocated among remaining participating employees. Benefits are payable upon
retirement, disability or separation from service. Distributions may be paid in
shares of the Bank's stock or in cash. The Plan includes a stock repurchase
option, whereby a participant electing to receive a distribution can elect to
sell the vested shares back to the Bank at its determined fair market value. At
December 31, 1997, the repurchase option was $986 per share. All shares are
considered outstanding for Earnings Per Share computations. The ESOP holds
433.33 shares of the Bank's stock at December 31, 1997.

   Compensation expense was $41,000 and $43,000 for the years ended December 31,
1997 and 1996, respectively. Dividends declared on ESOP shares were $34,666 for
both 1997 and 1996.

NOTE 14:    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:

CASH AND CASH EQUIVALENTS

   For these short-term instruments, the carrying amount approximates fair
value.

INVESTMENT SECURITIES

   Fair values for investment securities equal quoted market prices, if
available. If quoted market prices are not available, fair values are estimated
based on quoted market prices of similar securities.

LOANS

   The fair value of loans is estimated by discounting the future cash flows
using the current rates at which similar loans would be made to borrowers with
similar credit ratings and for the same remaining maturities. Loans with similar
characteristics were aggregated for purposes of the calculations. The carrying
amount of accrued interest receivable approximates its fair value.

DEPOSITS

   The fair value of demand deposits, savings accounts, NOW accounts and certain
money market deposits is the amount payable on demand at the reporting date
(i.e., their carrying amount). The fair value of fixed-maturity time deposits is
estimated using a discounted cash flow calculation that applies the rates
currently offered for deposits of similar remaining maturities. The carrying
amount of accrued interest payable approximates its fair value.

SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE

   For these short-term instruments, the carrying amount is a reasonable
estimate of fair value.

ADVANCES FROM FEDERAL HOME LOAN BANK

   Rates currently available to the Bank for debt with similar terms and
remaining maturities are used to estimate fair value of existing advances.

                     YEARS ENDED DECEMBER 31, 1997 AND 1996


LETTERS OF CREDIT AND LINES OF CREDIT

   The fair value of letters of credit and lines of credit is based on fees
currently charged for similar agreements or on the estimated cost to terminate
or otherwise settle the obligations with the counterparties at the reporting
date.

   The following table presents estimated fair values of the Bank's financial
instruments. The fair values of certain of these instruments were calculated by
discounting expected cash flows, which method involves significant judgments by
management and uncertainties. Fair value is the estimated amount at which
financial assets or liabilities could be exchanged in a current transaction
between willing parties, other than in a forced or liquidation sale. Because no
market exists for certain of these financial instruments and because management
does not intend to sell these financial instruments, the Bank does not know
whether the fair values shown below represent values at which the respective
financial instruments could be sold individually or in the aggregate.

NOTE 15:    SIGNIFICANT ESTIMATES AND CONCENTRATIONS

   Generally accepted accounting principles require disclosure of certain
significant estimates and current vulnerabilities due to certain concentrations.
Estimates related to the allowance for loan losses are reflected in the footnote
regarding loans. Current vulnerabilities due to certain concentrations of credit
risk are discussed in the footnote on commitments and credit risk.

NOTE 16:    COMMITMENTS AND CREDIT RISK

   Letters of credit are conditional commitments issued by the Bank to guarantee
the performance of a customer to a third party. Those guarantees are primarily
issued to support public and private borrowing arrangements, including
commercial paper, bond financing and similar transactions. The credit risk
involved in issuing letters of credit is essentially the same as that involved
in extending loans to customers.

     The Bank had total outstanding letters of credit amounting to $686,000 and
$800,000 at December 31, 1997 and 1996, respectively, with terms ranging from
five months to five years.

   Lines of credit are agreements to lend to a customer as long as there is no
violation of any condition established in the contract. Lines of credit
generally have fixed expiration dates. Since a portion of the line may expire
without being drawn upon, the total unused lines do not necessarily represent
future cash requirements. Each customer's creditworthiness is evaluated on a
case-by-case basis. The amount of collateral obtained, if deemed necessary, is
based on management's credit evaluation of the counterparty. Collateral held
varies but may include accounts receivable, inventory, property, plant and
equipment, commercial real estate and residential real estate. Management uses
the same credit policies in granting lines of credit as it does for
on-balance-sheet instruments.

   At December 31, 1997 and 1996, the Bank had granted unused lines of credit to
borrowers aggregating approximately $4,375,000 and $6,735,000 for commercial
lines and open-end consumer lines, respectively.


NOTE 17:    MERGER AGREEMENT

   On April 9, 1998, the Bank entered into a letter of intent to merge with
Liberty Bancshares, Inc., a Missouri based one-bank holding company with
approximately $80 million in total assets. The agreement formulates a
transaction whereby all of the outstanding stock of Sac River Valley Bank would
be exchanged for shares of Liberty Bancshares, Inc. The merger is subject to
regulatory and shareholder approval and, if approved, is anticipated to occur in
late 1998.

NOTE 1:     PRO FORMA PRESENTATION

   The unaudited pro forma combined financial statements assume a business
transaction between Liberty Bancshares, Inc. (Bancshares) and Sac River Valley
Bank (Sac River) (in the form of a merger) accounted for as a purchase. The pro
forma condensed balance sheet combines Bancshares' and Sac River's unaudited
balance sheets at June 30, 1998, giving effect to the merger as if such
transaction had occurred as of that date. The pro forma condensed consolidated
statements of income combine Bancshares historical consolidated statements of
income for the unaudited three-month period as of June 30, 1998, and the year
ended December 31, 1997, with the corresponding Sac River historical statements
of income for such periods, giving effect to the merger as if such transaction
had happened at the beginning of the earliest period.

   The unaudited historical consolidated financial statement data of Bancshares
as of June 30, 1998, and for the six months ended June 30, 1998, and the
unaudited historical financial statements of Sac River as of June 30, 1998, and
for the six months ended June 30, 1998, have been prepared on the same basis as
the historical information derived from audited financial statements, and in the
opinion of their respective managements, reflects all adjustments, consisting
only of normal recurring accruals, necessary for a fair presentation of the
financial position and results of operations for such periods.

   The pro forma information is presented for illustrative purposes only and is
not necessarily indicative of the actual operating results or financial position
of the combined entity that would have been achieved had the merger been
consummated at the dates presented, nor is it necessarily indicative of the
combined entity's future operating results or financial position. The unaudited
pro forma condensed financial statements do not incorporate any benefits from
cost savings or synergies of operations of the combined entity that may occur.
Bancshares and Sac River anticipate incurring direct transaction costs and
integration costs related to the merger.

   The pro forma condensed financial statements are based on the historical
consolidated financial statements of Bancshares and notes thereto and the
historical financial statements of Sac River and the notes thereto, and should
be read in conjunction with the financial statements of Bancshares and Sac River
included elsewhere in this Form S-4 filing.

             To record estimated cash out of approximately 28% of Sac River
             shareholders funded by borrowings on note payable. The borrowing

             years.  The borrowing will be amortized over a 10-year period.

NOTE 3:     PRO FORMA INCOME STATEMENT ADJUSTMENTS

    The pro forma income statement adjustment shown in the pro forma condensed
consolidated financial statements and denoted by a (5) reflects goodwill
amortization as if the transaction had occurred as of the beginning of the
applicable period presented. The goodwill will be amortized on a straight-line
basis over fifteen years. The adjustment also reflects interest expense (net of
related income taxes) for debt to be issued.


NOTE 4:     CALCULATION OF GOODWILL

    As stated in Note 1, the pending merger is accounted for utilizing the
purchase method of accounting and, accordingly, the net assets of Sac River are
adjusted to fair value. The components of the transaction assumed in the pro
forma condensed consolidated balance sheet are outlined as follows:

         Cash paid                               $      4,857,000
         Debt origination                               2,800,000
         Issuance of common stock                       7,700,000
                                                 ----------------
                                                       15,357,000
         Historical book value of Sac River           (11,159,000)
         Excess of cost over fair value of net
         assets acquired                         $      4,198,000
                                                 ================

               NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL
                                   STATEMENTS



NOTE 4:     CALCULATION OF GOODWILL (CONTINUED)

    The number of shares expected to be issued for the transaction is 260,450
shares of Bancshares stock, which is the difference between the number of Sac
River's total shares outstanding (10,000 shares) and the number of shares for
which it is expected the holder will exercise the cash option (2,667 shares),
multiplied by the exchange ratio of 35.516 shares of Bancshares stock for each
share of Sac River stock. The value assigned to the shares to be issued is
$29.56 per share, which is the equivalent cash price to be paid to Sac River
shareholders exercising the cash option.

    The fair value of the identifiable assets acquired and the liabilities
assumed by Bancshares at the transaction date are expected to materially
approximate their book values. Therefore, the excess cost over fair value of net
assets acquired has been allocated entirely to goodwill.

                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER  ("Agreement"),  made and entered into the
18th  day of  June,  1998,  by and  among  Sac  River  Valley  Bank,  a  banking
corporation  organized  under the laws of the State of Missouri  ("Sac  River"),
Liberty  Bank, a banking  corporation  organized  under the laws of the State of
Missouri (hereinafter referred to as "Liberty") and Liberty Bancshares,  Inc., a
Missouri  corporation  (hereinafter  referred  to as  "Bancshares"),  a one bank
holding  company  owning  all of the  issued and  outstanding  capital  stock of
Liberty  (all of said  corporations  being  hereinafter  sometimes  referred  to
collectively as the "Constituent Corporations").


                              W I T N E S S E T H:


         WHEREAS,  as of December 31, 1997,  the equity capital of Sac River was
$11,140,000.00,  divided into 10,000 shares of common stock, each of a par value
of $30.00 each,  surplus of $500,000.00,  undivided  profits,  including capital
reserves,   of   $10,315,000.00,   and   net   unrealized   holding   gains   on
available-for-sale securities of $25,000.00; and

         WHEREAS,  as of December  31, 1997,  the equity  capital of Liberty was
$7,603,000.00,  divided into 34,000 shares of common stock,  each of a par value
of $50.00 each,  surplus of  $5,592,000.00,  and  undivided  profits,  including
capital reserves, of $311,000.00; and

         WHEREAS,  Bancshares  has,  on  the  date  hereof,  authorized  capital
consisting of 5,000,000 shares of common stock, par value of $1.00 per share (as
approved by the  shareholders  of Bancshares  on May 19, 1998),  of which on the
date hereof 511,090 shares are issued and outstanding; and

         WHEREAS,  subject  to full due  diligence  and  final  approval  by the
respective  Boards of  Directors  of Sac River and  Bancshares,  the  respective
Boards of  Directors  of Sac River and  Bancshares  are of the opinion  that the
transactions described herein are in the best interests of the parties and their
respective  shareholders.  This  Agreement  provides for the  acquisition of Sac
River by  Bancshares  pursuant to the merger of Sac River with and into Liberty.
At the effective time of such merger,  the outstanding shares of common stock of
Sac River shall be converted into the right to receive shares of common stock of
Bancshares, cash, or a combination thereof, subject to the limitations set forth
herein.  As a result,  shareholders  of Sac River shall become  shareholders  of
Bancshares,  and Liberty,  as the wholly owned  subsidiary of Bancshares,  shall
continue to conduct,  under its  charter,  its banking  business and 

<PAGE>   173

the banking business formerly conducted by Sac River. The transactions described
in this Agreement are subject to the approvals of the shareholders of Sac River
and Liberty, the Board of Governors of the Federal Reserve System, the Federal
Deposit Insurance Corporation, the Missouri Division of Finance, and other
applicable federal and state regulatory authorities, and the satisfaction of
certain other conditions described in this Agreement. It is the intention of the
parties to this Agreement that the Merger, for federal income tax purposes,
shall qualify as a "reorganization" within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"); and

         WHEREAS,   the   Constituent   Corporations   desire  to  make  certain
representations,  warranties and agreements in connection with the Merger and to
set forth the terms and conditions of the Merger;

         NOW,   THEREFORE,   in  consideration  of  the  above  and  the  mutual
warranties,  representations,  covenants,  and agreements set forth herein,  the
parties hereto agree as follows:

                                   ARTICLE III

                           of common stock of Bancshares (the "Exchange Ratio").

         3.2     Adjstments to Exchange Ratio. In the event Bancshares changes
the number of shares of Bancshares common stock issued and outstanding prior to
the Effective Time as a result of a stock split, stock dividend, or similar
recapitalization with respect to such stock and the record date therefore (in
the case of a stock dividend) or the effective date thereof (in the case of a
stock split or similar recapitalization for which a record date is not
established) shall be prior to the Effective Time, the Exchange Ratio shall be
proportionately adjusted.

         3.3     Fractional Shares. Notwithstanding any other provision of this
Agreement, each holder of shares of Sac River common stock exchanged pursuant to
the Merger who would  otherwise  have been  entitled  to receive a fraction of a
share of  Bancshares  common stock (after  taking into account all  certificates
delivered  by such  holder)  shall  receive,  in  lieu  thereof,  cash  (without
interest) in an amount equal to such  fractional  part of a shares of Bancshares
common stock multiplied by the value of one share of Bancshares  common stock at
the Effective  Time. For purposes of this  Agreement,  the value of one share of
Bancshares  common  stock at the  Effective  Time  shall be $29.56  (subject  to
adjustment as provided in Section 3.2 hereof).  No such holder shall be entitled
to 

                                       5
<PAGE>   177

dividends,  voting rights, or any other rights as a shareholder in respect of
any fractional shares.

         3.4     Election to Receive Optional Per Share Cash Amount. Elections
by shareholders of Sac River to receive Optional Per Share Cash Amounts shall be
made by mailing or delivering to the Exchange Agent (as defined below) the Form
of Election delivered to the shareholders of Sac River with the Proxy Statement
(as defined in Section 8.2 hereof). To be effective, a Form of Election must be
properly completed, signed and submitted by the shareholder no later than the
date of the special meeting of the shareholders of Sac River held to approve the
Merger (the "Election Deadline"). In the event the special shareholders meeting
is adjourned to a specified date no longer than ninety (90) days after such
adjournment, the Election Deadline shall be such specified date (the "Extended
Electing Deadline"). Sac River and Bancshares shall mail the Form of Election
with the Proxy Statement to all holders of Sac River common stock on the record
date of the Sac River special shareholders' meeting and shall make the Form of
Election available to all persons who become holders of Sac River common stock
subsequent to such day and no later than the close of business on the business
day prior to the Extended Election Deadline. All elections by shareholders to
receive Optional Per Share Cash Amounts may be revoked or amended until the
Extended Election Deadline. If no such election is filed by a Sac River
shareholder, no Optional Per Share Cash Amount shall be made to the shareholder,
and all of the Sac River shares held by the shareholder shall be exchanged for
Bancshares common stock in accordance with the Exchange Ratio (except for the
Mandatory Per Share Cash Amount) Each Sac River shareholder who does not vote in
favor of the Merger as of the Extended Election Deadline shall be deemed,
subject to the right hereinabove provided for amendment or revocation of the
election and subject to the provisions of Section 3.9 hereof, to have made an
election to receive Optional Per Share Cash Amounts with respect to his or her
shares, regardless of the actual Forms of Election submitted by said
shareholder.

         3.5     Exchange Procedures. At the Closing, Bancshares shall deposit
with Husch & Eppenberger, LLC (the "Exchange Agent"), for the benefit of the
then holders of shares of Sac River common stock, certificates dated as of the
Closing Date representing the shares of Bancshares common stock, the cash to be
paid in lieu of fractional shares, the Optional Per Share Cash Amounts (if any),
and the Mandatory Per Share Cash Amounts (such cash and certificates of
Bancshares common stock, together with any dividend or distributions with
respect thereto, being hereinafter referred to as the "Exchange Fund") to be
issued and paid pursuant to Section 3.1 hereof in exchange for the outstanding
shares of Sac River common stock. Within five (5) business days after the
Closing Date, Bancshares shall cause the Exchange Agent to mail to each holder
of record as of the Closing Date of a Sac River certificate or certificates (i)
a letter of transmittal which will 


                                       6
<PAGE>   178

specify that delivery shall be effective, and risk of loss and title to the Sac
River certificate(s) shall pass, only upon delivery of the Sac River
certificate(s) to the Exchange Agent and which shall be in such form and have
such other provisions as Bancshares and Sac River may reasonably specify, and
(ii) instructions for use in effecting the surrender of the Sac River
certificate(s) in exchange for a certificate representing shares of Bancshares
common stock, cash to be paid in lieu of any fractional share, the Optional Per
Share Cash Amount (if any) and the Mandatory Per Share Cash Amount. Upon
surrender of a shareholder's Sac River certificate or certificates for
cancellation to the Exchange Agent together with such letter of transmittal,
duly executed, the holder of such Sac River certificate(s) shall be entitled to
receive in exchange therefore, within ten (10) business days following said
surrender, (1) a certificate representing the applicable number of whole shares
of Bancshares common stock, and (2) a check representing the amount of the cash
to be paid in lieu of a fractional share, if any, the Optional Per Share Cash
Amount (if any) and the Mandatory Per Share Cash Amount, and the Sac River
certificate(s) so surrendered shall forthwith be cancelled; provided, however,
that any Sac River shareholder who does not vote in favor of the Merger shall
not be entitled to receive said cash earlier than sixty (60) days after the
Effective Time. Except for said shareholders (who, except as provided in Section
3.9 hereof, shall receive interest at the rate of 9% per annum during the period
of sixty (60) days following the Effective Time), no interest will be paid on
cash in lieu of fractional shares, the Optional Per Share Cash Amount (if any),
and the Mandatory Per Share Cash Amount. Any applicable stock transfer taxes
shall be paid by Bancshares. Adoption of this Agreement by the shareholders of
Sac River and Liberty shall constitute ratification of the appointment of the
Exchange Agent.

         3.6     Rights of Former Sac River Shareholders. At the Effective Time,
the stock transfer books of Sac River shall be closed as to holders of Sac River
common stock immediately prior to the Effective Time and no transfer of Sac
River common stock by any such holder shall thereafter be made or recognized.
Until surrendered for exchange in accordance with the provisions of Section 3.5
hereof, each certificate theretofore representing shares of Sac River common
stock shall from and after the Effective Time represent for all purposes only
the right to receive the consideration provided in Section 3.1 hereof in
exchange therefore, subject, however, to Bancshares' obligation to pay any
dividends or make any other distributions with a record date prior to the
Effective Time which have been declared or made by Sac River in respect of such
shares of Sac River common stock in accordance with the terms of this Agreement
and which remain unpaid at the Effective Time. Whenever a dividend or other
distribution is declared by Bancshares on the Bancshares common stock, the
record date for which is at or after the Effective Time, the declaration shall
include dividends or other distributions on all shares of 


                                       7
<PAGE>   179

Bancshares common stock issuable pursuant to this Agreement, but beginning
thirty (30) days after the Effective Time no dividend or other distribution
payable to the holders of record of Bancshares common stock as of any time
subsequent to the Effective Time shall be delivered to the holder of any
certificate representing shares of Sac River common stock issued and outstanding
at the Effective Time until such holder surrenders such certificate (or an
affidavit in lieu thereof pursuant to Section 3.8 hereof) for exchange as
provided in Section 3.5 of this Agreement. However, upon surrender of Sac River
common stock certificate, both the Bancshares common stock certificate (together
with all such undelivered dividends or other distributions without interest) and
any undelivered dividends and cash payments payable thereunder (without
interest) shall be delivered and paid with respect to each share represented by
such certificate.

         3.7     Termination of Exchange Fund. Any portion of the Exchange Fund
that remains unclaimed by the shareholders of Sac River for twelve (12) months
after the Closing Date shall be paid to Bancshares. Any shareholders of Sac
River who have not theretofore complied with this Article III shall thereafter
look only to Bancshares for payment of their shares of Bancshares common stock,
cash in lieu of any fractional share of Bancshares common stock, Optional Per
Share Cash Amount (if any) and Mandatory Per Share Cash Amount, without any
interest thereon. Notwithstanding the foregoing, neither the Exchange Agent nor
Bancshares shall be liable to any former holder of shares of Sac River common
stock for any amount properly delivered to a public official pursuant to any
applicable abandoned property, escheat or similar laws.

         3.8     Lost or Destroyed Shares. In the event any Sac River
certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Sac River certificate to be
lost, stolen or destroyed and, if required by the Exchange Agent, the execution
and delivery of an indemnity agreement whereby said person shall agree to
indemnify the Exchange Agent and Bancshares against any claim which may be made
against it with respect to such Sac River certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Sac River certificate the
shares of Bancshares common stock and cash in an amount as determined in
accordance with Section 3.1 hereof, deliverable in respect thereof pursuant to
this Agreement.

         3.9     Dissenters' Rights. Each issued and outstanding share of Sac
River common stock, the holder of which has validly asserted dissenters' rights
pursuant to RSMo. Section 362.730 and has not effectively withdrawn or lost such
rights, shall not be converted into or represent a right to receive the
consideration specified in Section 3.1 hereof, but the holder thereof shall be
entitled only to such rights as are granted by RSMo. Section 362.730. In the 
event the holder of Sac River common stock validly asserts dissenter's rights
pursuant to RSMo. Section 362.730, any cash held by the Exchange Agent 



                                       8
<PAGE>   180

with respect to said shareholder's shares shall be paid by the Exchange Agent to
the Surviving Bank. Each shareholder entitled, pursuant to the provisions of
RSMo. Section 362.730, to payment for his or her shares of Sac River common 
stock, shall receive payment therefore from the Surviving Bank (but only after
the amount thereof shall have been agreed upon or determined pursuant to
such provisions) and such shares of Sac River common stock shall be cancelled.
If any holder of shares of Sac River common stock who asserts dissenters'
rights under RSMo. Section 362.730 effectively withdraws or loses (through
failure to  perfect or otherwise) such rights, each such share of Sac River
common stock shall be converted into the right to receive the consideration
specified in Section 3.1 hereof.

                                   ARTICLE IV
                   REPRESENTATIONS AND WARRANTIES OF SAC RIVER

         Sac River hereby  represents  and warrants to Liberty and Bancshares as
follows:

         4.1     Organization, Standing, and Power. Sac River is a banking
corporation  duly organized,  validly  existing,  and in good standing under the
laws of the  State  of  Missouri,  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.  Copies of the  charter  and  by-laws of Sac River,  as
certified  by the  secretary of Sac River,  have  heretofore  been  delivered to

         4.2     Subsidiaries. Sac River has no subsidiaries.

         4.3     Capital Structure.

                 (a)   As of the date hereof, the authorized capital stock of 
         Sac River consists of ten thousand (10,000) shares, of common stock,
         par value $30.00 per share.

                 (b)   As of the date  hereof,  ten thousand  (10,000)  shares 
         of common stock of Sac river are issued and outstanding, and no shares
         of common stock are held in treasury.

                 (c)   Except as set forth in the Sac  River  Disclosure  Letter
         (which is a letter  delivered by Sac River to Bancshares  within thirty
         (30)  days  after  the  date  hereof,  the  receipt  of  whereof  to be
         acknowledged  by Bancshares,  and which  identifies,  as to each matter
         disclosed  therein,  the Section of this  Agreement to which the matter
         relates),  as of  the  date  hereof,  Sac  River  has  not  issued  any
         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").  



                                       9
<PAGE>   181

         All outstanding shares of Sac River capital stock are validly issued,
         fully paid and non-assessable and not subject to or issued in violation
         of any preemptive rights, and there are no options, warrants, calls,
         rights, or agreements of any character whatsoever to which Sac River is
         a party or by which it is bound obligating Sac River to issue, deliver
         or sell, or cause to be issued, delivered or sold, additional shares of
         its capital stock or Voting Debt or obligating Sac River to grant,
         extend or enter into any such option, warrant, call, right, or
         agreement. Immediately after the Effective Time, there will be no
         option, warrant, call, right or agreement obligating Sac River to
         issue, deliver or sell, or cause to be issued, delivered or sold, any
         shares of its capital stock or Voting Debt or obligating Sac River to
         grant, extend or enter into any such option, warrant, call, right or
         agreement.

                 (d)   Sac  River  has not  purchased,  redeemed,  cancelled  or
         otherwise  acquired any of its capital  stock or Voting Debt during the
         two (2) years preceding the date hereof,  and there are no obligations,
         contingent  or  otherwise,  of  Sac  River  to  repurchase,  redeem  or
         otherwise acquire any shares of its capital stock or Voting Debt.

                 (e)   As of  December  31,  1997,  Sac  River  had  capital  of
         $11,140,000.00,  divided  into ten thousand  (10,000)  shares of common
         stock, surplus of $500,000.00, and undivided profits, including capital
         reserves,  of  $10,315,000.00,  and net  unrealized  holding  gains  on
         available-for-sale securities of $25,000.00.

         4.4     Authority.

                 (a)   Sac River has all requisite  corporate power and 
         authority necessary to execute, deliver and perform its obligations
         under this Agreement and to consummate the transactions contemplated
         hereby. The execution, delivery, and performance of this Agreement, and
         the consummation of the transactions contemplated herein, including the
         Merger, have been duly and validly authorized by all necessary
         corporate action in respect thereof on the part of Sac River, subject
         to the approval of this Agreement by the Board of Directors and the
         holders of two-thirds (2/3) of the outstanding shares of Sac River
         common stock, which is the only shareholder vote required for approval
         of this Agreement and consummation of the Merger by Sac River. This
         Agreement has been duly executed and delivered by Sac River, and
         constitutes a valid and binding obligation of Sac River enforceable in
         accordance with its terms, subject to such requisite Board of Directors
         and shareholder approval and compliance with the provisions of RSMo.
         Sections 362.610 to 362.810, inclusive (the "Missouri Bank Merger 
         Laws"), the Securities Act of 1933 (the "Securities Act"), the 
         Securities Exchange Act of 1934 (the "Exchange

         Act"), and the securities or "blue sky" laws of the various states
         (collectively the "Securities Laws") and consents, authorizations or
         approvals required from regulatory authorities.

                 (b)   The execution and delivery of this Agreement does not, 
         and the consummation of the transactions contemplated herein, 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 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 the provisions of (i) the
         charter or by-laws of Sac River, or (ii) any loan or credit agreement,
         note, mortgage, indenture, lease, Sac River Benefit Plan (as
         hereinafter defined) or other agreement, obligation, instrument,
         permit, franchise, license, judgment, order, decree, statute, law,
         ordinance, rule or regulation applicable to Sac River, or its
         properties or assets, which Violation would have a material adverse
         effect on the business, operations, prospects or financial condition of
         Sac River (a "Sac River Material Adverse Effect").

         4.5     Financial Statements.

                 (a)   The  statement of  financial  condition of Sac River as 
         of December 31, 1997, and the related statements of income, cash flow
         and shareholder's equity for the period ending December 31, 1997 (the
         "Sac River Latest Statement Date"), in the form prepared for Sac
         River's internal use, copies which have been furnished by Sac River to
         Bancshares, and the statement of financial condition of Sac River, as
         of March 31, 1998, and the related statements of income, cash flow and
         shareholder's equity for the three (3) months then ended, in the form
         prepared for Sac River's internal use, copies of which have been
         furnished by Sac River to Bancshares (collectively the "Sac River
         Financial Statements") have been prepared in accordance with generally
         accepted accounting principles as utilized in the Sac River Financial
         Statements applied on a consistent basis (except as may be indicated
         therein or in the notes thereto), and present fairly the financial
         position of Sac River, at the dates and results of operations, changes
         in shareholder's equity and cash flows for the periods stated therein.
         In the case of interim fiscal periods, all adjustments, consisting only
         of normal reoccurring items, which management of Sac River believes
         necessary for a fair presentation of such financial information, have
         been made, subject to year end audit 



                                       11
<PAGE>   183

         adjustments, none of which could reasonably be expected to have a Sac
         River Material Adverse Effect.

                 (b)   Except as and to the extent set forth in the  statement 
         of financial condition of Sac River as of March 31, 1998, or in the
         notes thereto, Sac River has no liabilities or obligations of any
         nature (whether accrued, absolute, contingent or otherwise) that would
         be required to be reflected on a statement of financial condition, or
         in the notes thereto, prepared in accordance with generally accepted
         accounting principles, except (i) for liabilities or obligations
         incurred in the ordinary course of business since the Sac River Latest
         Statement Date that would not, individually or in the aggregate, have a
         Sac River Material Adverse Effect, or (ii) as otherwise reflected in
         the Sac River Reports (as defined below) filed prior to the date of
         this Agreement. Except as set forth in the Sac River Disclosure Letter,
         Sac River has no liabilities or obligations of any nature (whether
         accrued, absolute, contingent or otherwise) that are not required to be
         reflected on a balance sheet, or in the notes thereto, except for
         liabilities or obligations that do not, individually or in the
         aggregate, have a Sac River Material Adverse Effect.

                 (c)   Without limitation to the foregoing, Sac River's 
         allowance for loan losses included in the Sac River Financial
         Statements as of March 31, 1998, was $854,231.02. To the knowledge of
         sac River, the amount of such allowance for loan losses was adequate to
         absorb reasonably expected losses in the loan portfolio of Sac River.
         To the knowledge of Sac River, there are no facts which would cause it
         to increase the level of such allowance for loan losses. To the
         knowledge of Sac River, the documentation relating to loans made by Sac
         River and relating to all security interests, mortgages and other liens
         with respect to all collateral for such loans, taken as a whole is
         adequate for the enforcement of the material terms of such loans and of
         the related security interests, mortgages and other liens, except as
         enforcement may be limited by bankruptcy or similar laws or principles
         of equity. To the knowledge of Sac River, the terms of such loans and
         of the related security interests, mortgages and other liens comply in
         all material respects with all applicable laws, rules and regulations
         (including laws, rules and regulations relating to the extension of
         credit). Except as set forth in the Sac River Disclosure Letter, (i) as
         of March 31, 1998, there are no loans, leases, other extensions of
         credit or commitments to extend credit of Sac River that have been or
         should be, in accordance with generally accepted accounting principles,
         classified by Sac River as non-accrual, as restructured, as ninety days
         past due, as still accruing and doubtful of collection or any
         comparable classification, and (ii) Sac River has provided Bancshares
         true, correct and 



                                       12
<PAGE>   184

         complete in all material respects, such written information concerning
         the loan portfolio of Sac River as requested. Notwithstanding any
         provision in this Section 4.5(c) to the contrary, Sac River makes no
         representation or warranty with respect to the collectability of any
         loan.

         4.6     Reports. Sac River has filed all reports, registrations and
statements, together with any amendments required to be made with respect
thereto, that were or are required to be filed with (i) the FDIC, (ii) the
Division of Finance, and (iii) any other applicable federal or state agencies or
bank authorities (all such reports and statements are collectively referred to
herein as the "Sac River Reports"). As of their respective dates, the Sac River
Reports filed prior to the date hereof complied in all material respects with
all of the statutes, rules and regulations enforced or promulgated by any
regulatory authority which they are filed, and did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

         4.7     Authorizations; Compliance With Applicable Laws.

                 (a)   Sac River holds all authorizations, permits, licenses,
         variances, exemptions, orders and approvals of all governmental
         entities which are material to the operations of its business (the "Sac
         River Permits"). All such Sac River Permits are in full force and
         effect as of the Closing Date, and Sac River is in compliance with the
         terms of the Sac River Permits, except where the failure to so comply
         could not reasonably be expected to have a Sac River Material Adverse
         Effect. Except as disclosed in the Sac River Reports filed prior to the
         date of this Agreement or in the Sac River Disclosure Letter, the
         business of Sac River is not deemed, and has not been, conducted in
         violation of any domestic (federal, state or local) law, statute,
         ordinance or regulation of any governmental entity (collectively
         "Laws") except for possible violations which individually or in the
         aggregate do not and, insofar as reasonably can be foreseen, in the
         future will not, have a Sac River Material Adverse Effect. Except as
         set forth in the Sac River Disclosure Letter, as of the date hereof, no
         investigation or review by any governmental entity with respect to Sac
         River is pending or, to the knowledge of Sac River, threatened, nor has
         any governmental entity indicated an intention to conduct the same. The
         deposits of Sac River are insured by the FDIC to the extent provided by
         law.

                 (b)   The Sac River Disclosure Letter identifies each parcel of
         real estate currently owned, leased or otherwise possessed or
         controlled by Sac River on the date of this Agreement, including real
         estate owned as a result of 



                                       13

         foreclosure and properties managed or controlled by Sac River in
         connection with its lending or fiduciary obligations (collectively, the
         "Sac River Property"). Except as set forth in the Sac River Disclosure
         Letter, to the knowledge of Sac River, none of the Sac River Property
         owned or leased by Sac River for use in the operation of its business
         is in violation of any applicable zoning ordinance or other law,
         regulation or requirement relating to operation of any properties used,
         including, without limitation, applicable federal, state and local
         laws, rules and regulations relating to the environment or to human
         health and safety associated with the environment (collectively
         "Environmental Laws"), other than violations that, in the aggregate,
         would not have a Sac River Material Adverse Effect; and Sac River has
         not received any notice of any such violation, or the existence of any
         condemnation proceeding with respect to any Sac River Property. Except
         as set forth in the Sac River Disclosure Letter, to the knowledge of
         Sac River, no Toxic Substances (as defined below) have been deposited
         or disposed in, on or under any Sac River Property during the period in
         which Sac River has owned, occupied, managed, controlled or operated
         such properties, except to the extent the same would not have a
         Material Adverse Effect. Except as set forth in the Disclosure Letter,
         to Sac Rivers' knowledge, no portion of the Sac River Property has ever
         been used as a dump or gasoline service station by any person,
         including past owners, occupants and operators of such properties. To
         the knowledge of Sac River, there are no underground or aboveground
         storage tanks (whether or not currently in use) located on or under the
         Sac River Property, and no underground tank previously located on the
         Sac River Property has been removed therefrom. To the knowledge of Sac
         River, there are no conditions or circumstances in connection with the
         Sac River Property that could reasonably be anticipated to (i) cause
         any Sac River Property to be subject to any restrictions on ownership,
         occupancy, use or transferability under any applicable Environmental
         laws, or (ii) materially reduce the value of any Sac River Property. To
         the knowledge of Sac River, Sac River has not been identified as a
         potentially responsible party in a matter arising under any
         Environmental Laws. For purposes of this Agreement, (1) "Toxic
         Substances" shall mean petroleum or petroleum based substance or waste,
         solid waste, PCBs, pesticides, herbicides, lead, radioactive materials,
         asbestos or asbestos containing materials, ureaformaldehyde foam
         installation, or substances defined as "hazardous substances" or "toxic
         substances" in any Environmental Laws, and (2) materials will be
         considered to be deposited or disposed in, on or under any real
         property if such materials have been stored, treated, recycled, used or
         accidentally or intentionally spilled, released, dumped, emitted, or
         otherwise placed, deposited or disposed of, or used in any
         construction, in, on or under such property.

         4.8     Litigation and Claims. Except as disclosed in the Sac River 
Reports filed prior to the date of this Agreement or in the Sac River Disclosure
Letter:

                 (a)   Sac River is not subject to any continuing order of, or
         written agreement or memorandum or understanding with any federal or
         state banking or insurance authority or other governmental entity, or
         any judgment, order, writ, injunction, decree or award of any
         governmental entity or arbitrator, including, without limitation,
         cease-and-desist or other orders of any banking authority,

                 (b)   There is no action, suit, litigation, proceeding or     
         arbitration against or affecting Sac River, or to the knowledge of Sac
         River, any directors, officers, employees or agents of Sac River (in
         their respective capacities as directors, officers, employees or
         agents) pending or, to the knowledge of Sac River, threatened, which
         would, if adversely determined, have a Sac River Material Adverse
         Effect or, to the knowledge of Sac River, any basis therefore, and

                 (c)   There are no uncured material violations, or violations
         with respect to which material refunds or restitutions may be required,
         cited in any compliance report to Sac River as a result of the
         examination by any bank regulatory authority.

         4.9 Taxes.  Sac River has filed all tax returns required to be filed by
it and has paid or has set up an adequate  reserve for the payment of, all taxes
required  to be paid as  shown  on  such  returns,  except  to the  extent  such
nonpayment  did not  result in a Sac River  Material  Adverse  Effect.  The most
recent Sac River financial statements contained in the Sac River Reports reflect
an adequate  reserve for all taxes  payable by Sac River  accrued to the date of
such financial statements. The Sac River Disclosure Letter sets forth, as of the
date hereof, the following information with respect to Sac River:

                  (a) Whether  there is an  examination  pending by the Internal
         Revenue  Service  ("IRS") with respect to Sac River and, if so, the tax
         years involved,

                  (b) Whether  Sac River has  executed or filed with the IRS any
         agreement which is still in effect  extending the period for assessment
         and  collection of any federal tax, and if so, the tax years covered by
         such agreement and the expiration of such extension, and

                  (c) Whether  there are any  existing  material  disputes as to
         state or local taxes.


                                       15
<PAGE>   187

                 There are no liens for taxes upon the assets of Sac River,
         except for statutory liens for taxes not yet delinquent or the validity
         of which is being contested in good faith by appropriate proceedings
         and, in either case, only if adequate reserves therefor have been
         established on Sac River's books in accordance with generally accepted
         accounting principals. Except as disclosed in the Sac River Disclosure
         Letter, Sac River is not a party to any action or proceeding by any
         governmental authority for assessment and collection of taxes, and no
         claim for assessment and collection of taxes has been asserted against
         it. For purposes of this Agreement, the term "tax" shall include all
         federal, state and local income, profits, franchise, gross receipts,
         payroll, sales, employment, use, personal and real property,
         withholding, excise and other taxes, duties or assessments of any
         nature whatsoever, together with all interest, penalties and additions
         imposed with respect to such amounts. Sac River has withheld from its
         employees (and timely paid to the appropriate governmental agency)
         amounts which are proper and accurate in all material respects for all
         periods through the date hereof in material compliance with all tax
         withholding provisions of applicable federal, state and local laws
         (including, without limitation, income, social security and employment
         tax withholding for all types of compensation).

         4.10    Certain Agreements. Except as discussed in the Sac River
Reports filed prior to the date of this Agreement or as disclosed in the Sac
River Disclosure Letter, and except for this Agreement, Sac River is not a party
to any oral or written (i) consulting or employment agreement or other agreement
providing any term of employment, compensation guarantee, or severance benefit,
(ii) union or collective bargaining agreement, (iii) agreement or plan,
including any stock option plan, stock appreciation right plan, restricted stock

the benefits of which will be calculated on the basis of the transactions
contemplated by this Agreement, (iv) contract, agreement or understanding to

                                       16

agreement. Except as set forth in the Sac River Disclosure Letter, Sac River is
not in Violation of any loan or credit agreement, note, mortgage, indenture or
other agreement, obligation or instrument applicable to Sac River or its
properties or assets, except for any such Violations that would not,

         4.11    Benefit Plans.

                 (a)   The Sac River Disclosure Letter lists (i) each employee  
         bonus, incentive, deferred compensation, stock purchase, stock

         the meaning of Section 3(3) of the Employee Retirement Income Security
         Act of 1974, as amended ("ERISA")) (collectively "Sac River Benefit
         Plans"), which Sac River maintains or to which Sac River contributes on
         behalf of current or former employees. Except as disclosed in the Sac
         River Disclosure Letter, to the knowledge of Sac River, all of the Sac
         River Benefit Plans listed in the Sac River Disclosure Letter comply
         with all applicable requirements of the Internal Revenue Code, ERISA
         and all other applicable federal and state laws and regulations,
         including, without limitation, the reporting and disclosure
         requirements of ERISA. Each of the Sac River Benefit Plans that is
         intended to be a pension, profit sharing, stock bonus, thrift, savings
         or employee stock ownership plan that is qualified under Code
         Section 401(a), has been determined by the IRS to so qualify under Code
         Section 401(a), and, except as disclosed in the Sac River Disclosure 
         Letter, to the knowledge of Sac River, there exists no circumstances
         that would adversely affect the qualified status of any Sac River
         Benefit Plan under that Section. Except as set forth in the Sac River
         Disclosure Letter, there is no pending or, to the knowledge of Sac
         River, threatened litigation, governmental proceeding or investigation
         against or relating to any Sac River Benefit Plan, and to the
         knowledge of Sac River there is no reasonable basis for any material
         proceedings, claims, actions or proceedings against Sac River, any Sac
         River Benefit Plan, or any fiduciary of any Sac River Benefit Plan.
         Except as set forth in the Sac River Disclosure Letter, neither Sac
         River nor any party in interest (as defined in Section 3(14) of ERISA
         and Code Section 4975(e)) nor any Sac River Benefit Plan has engaged
         in a "prohibited transaction" (as defined in Section 406 of ERISA and
         Code Section 4975(c)) since the date on which said Sections became
         applicable to such Plan, and no Sac River Benefit Plan has engaged in
         a transaction 


                                       17
<PAGE>   189

         involving the purchase or sale of employer securities by such Plan
         from or to a "disqualified person" (within the meaning of Code Section
         4975), other than pursuant to an exemption provided therein. All Sac
         River Benefit Plans that are group health plans, within the meaning of
         Code Section 4980B or Section 601 of ERISA, have been operated in
         material compliance with the group health plan continuation coverage
         requirements of Code Section 4980B and Section 601 of ERISA to the
         extent such requirements are applicable.

                 (b)   There has been no amendment to, written interpretation
         of, or announcement (whether or not written) relating to, or any change
         in employee participation or coverage under, any Sac River Benefit Plan
         that is not reflected in the text of such Sac River Benefit Plan which
         would materially increase the expense (whether or not such expense is
         recognized under generally accepted accounting principles) to the
         employer whose employees are covered by such Sac River Benefit Plan.
         Except as expressly provided by applicable law or the terms of a Sac
         River Benefit Plan, no condition exists that would prevent the
         amendment or termination of any Sac River Benefit Plan with respect to
         any employee. All employee and employer contributions with respect to
         employees which are due and owing as of the Closing Date pursuant to
         the Sac River Benefit Plans have been made or will be accrued on the
         Closing Date Financial Statements and, except for such accrued
         liabilities, there are as of the Closing Date no other liabilities of
         Sac River with respect to the Sac River Benefit Plans.

                 (c)   Sac River has delivered to Bancshares copies of (i) each
         Sac River Benefit Plan or if no plan document exists, a written
         summary of the material terms thereof, (ii) current summary plan
         descriptions of each Sac River Benefit Plan for which they are

         and (vii) the most recent audited financial statements for each Sac
         River Benefit Plan for which audited financial statements are required
         by ERISA.

                 (d)   The Sac River Disclosure Letter describes any obligation
         that Sac River has to provide health and welfare benefits to retirees
         or other former employees or their dependents (other than rights
         arising solely under Section 601 



                                       18
<PAGE>   190

         of ERISA or Code Section 4980B) including information as to the number
         of retirees, other former employees and dependents entitled to
         such coverage and their ages.

         4.12    Insurance. Sac River is presently insured, and during each of
the past five calendar years has been insured, for reasonable amounts with
financially sound and reputable insurance companies against such risks as, to
the knowledge of Sac River, companies engaged in the similar business would, in
accordance with good business practice, customarily be insured. Sac River does
not have any liability for material unpaid premiums or premium adjustments not
properly reflected on the Sac River Financial Statements and no notice of
cancellation or termination has been received by Sac River with respect to any
material insurance policy currently in effect. Within the last five years,
except as disclosed in the Sac River Disclosure Letter, Sac River has not been

coverage been limited in any material respect as to any assets or operations, by
any insurance carrier to which it has applied for any such insurance or with

         decrease the rate of business done with Sac River (except for changes
         in the ordinary course of business) such as to, individually or in the
         aggregate, have a Sac River Material Adverse Effect.

         4.14    Properties, Leases and Other Agreements. Except as may be
reflected in the Sac River Financial Statements, for any lien for current taxes
not yet delinquent, for pledges to secure deposits and for such other liens,
security interests, claims, charges, options or other encumbrances or
imperfections of title which do not materially affect the value of personal or
real property reflected in the Sac River Financial Statements or acquired since
the date of such Financial Statements and which do not materially interfere with
or impair the present and continued use of such property, Sac River has good
title, free and clear of any liens, security interests, claims, charges, options
or other encumbrances, to all of the personal and real property reflected in the
Sac River Financial Statements, and all real and personal property acquired
since the date of such Statements, except such real and personal property as has
been disposed of in the ordinary course of business. The Sac River Disclosure
Letter lists all acquisitions or dispositions of capital assets planned as of
the date of this Agreement by Sac River, other than individual transactions with

personal property to which Sac River is a party. Sac River, as lessee, has a
valid and existing leasehold interest under each of such leases, true and
correct copies of which Sac River has delivered to Bancshares. There is not,
under any of such leases relating to real property or any other material leases,
any material existing default by Sac River, or, to the knowledge of Sac River,
any other party thereto, or any event with notice or lapse of time or both would
constitute such a material default.

         4.15    Votes Required. The affirmative vote of holders of two-thirds

holders of any class of Sac River capital stock necessary to approve this
Agreement and the transactions contemplated hereby. 



                                       21
<PAGE>   193

         4.16    Tax Matters. Sac River, to its knowledge, has not taken or 
agreed to take any action which would prevent the Merger from qualifying as one
or more reorganizations under Code Section 368(a)(1).

         4.17    Regulatory Impediments. As of the date hereof, Sac River is
unaware of the existence of any factor that would materially delay or materially
hinder the issuance of any of the  required  regulatory  approvals  necessary to
consummate the Merger or the other transactions  contemplated hereby, other than
any protest by any non-governmental parties.

         4.18    Full Disclosure. The representation and warranties of Sac River
contained in this  Agreement do not omit any material fact necessary to make the
statements  contained  therein,  in light of the circumstances  under which they
were made,  not  misleading.  There is no fact known to Sac River  which has not
been  disclosed  to  Bancshares  pursuant  to  this  Agreement,  the  Sac  River
Disclosure Letter and the Sac River Reports,  all taken as a whole,  which would
reasonably  be  expected  to have a Sac  River  Material  Adverse  Effect on the
ability of Bancshares or Sac River to consummate the  transactions  contemplated
hereby.

                 (d)   Bancshares has not purchased, redeemed, cancelled or

         5.4     Authority. Bancshares has all requisite corporate power and
authority to enter into this Agreement and the Merger and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby and
thereby have been duly authorized by all necessary corporate action on the part
of Bancshares. This Agreement has been duly executed and delivered by Bancshares
and, subject to appropriate Board of Directors and shareholder approval and
compliance with the Missouri Bank Merger Laws and Securities Laws and consents,
authorizations and approvals from regulatory authorities, constitutes a valid
and binding obligation of Bancshares enforceable in accordance with its terms.
The execution and delivery of this Agreement does not, and the consummation of
the transactions contemplated hereby will not, result in any Violation pursuant
to any provision of (a) the articles of incorporation, charter or by-laws of
Bancshares or Liberty or (b) any loan or credit agreement, note, mortgage,
indenture, lease, Benefit Plan maintained by Bancshares or other agreement,
obligation, instrument, permit, franchise, license, judgment, order, decree,
statute, law ordinance, rule or regulation applicable to Bancshares or Liberty
or their respective properties or assets, which Violation pursuant to this
clause (b) would have a material adverse effect on the business, operations,
prospects or financial condition of Bancshares and Liberty taken as a whole (a
"Bancshares Material Adverse Effect"). Other than in connection or in compliance
with the provisions of The General and Business Corporation Law of Missouri (the
"Missouri General Corporation Law"), the Missouri Bank Merger Laws, the
Securities Laws, and consents, authorizations, approvals, notices of exemptions
required from the FDIC, the Division of Finance, or under the federal Bank
Holding Company Act ("BHC Act"), no consent, approval, order or authorization
of, or registration, declaration or filing with, any governmental entity is
required on the part of Bancshares or Liberty in connection with the execution
and delivery of this Agreement or the consummation by Bancshares or Liberty of
the transactions contemplated hereby and thereby, the failure to obtain which
would have a Bancshares Material Adverse Effect.

         5.5     Bancshares Financial Statements.

                 (a)   The consolidated balance sheets of Bancshares and Liberty
         as of December 31, 1997 and the related consolidated statements of
         income, consolidated statements of cash flows and consolidated
         statements of stockholders' equity for the period ended December 31,
         1997 (the "Bancshares Latest Statement Date") accompanied by the
         unqualified opinion of Baird, Kurtz & Dobson, copies of which have been
         furnished by Bancshares to Sac River; and the unaudited consolidated
         balance sheet of Bancshares and Liberty as of March 31, 1998 and the
         related consolidated statement of income, consolidated statement of
         cash flows and consolidated statement of stockholders' equity for the
         three (3) months then ended in 



                                       24
<PAGE>   196

         the form prepared for Bancshares internal use, copies of which have
         been furnished by Bancshares to Sac River (collectively, the
         "Bancshares Financial Statements"), have been prepared in accordance
         with generally accepted accounting principles as utilized in the
         Bancshares Financial Statements applied on a consistent basis (except
         as may be indicated therein or in the notes thereto), and present
         fairly the consolidated financial condition of Bancshares and Liberty
         at the dates, and the consolidated results of operations, changes in
         stockholders' equity and cash flows for the periods, stated therein. In
         the case of interim fiscal periods, all adjustments, consisting only of
         normal recurring items, which management of Bancshares believes
         necessary for a fair presentation of such financial information, have
         been made, subject to year-end audit adjustments, none of which could
         reasonably be expected to have a Bancshares Material Adverse Effect.

                 (b)   Except as and to the extent set forth on the consolidated
         balance sheets of Bancshares and Liberty, as of March 31, 1998, or in
         the notes thereto, neither, Bancshares nor Liberty has any liabilities
         or obligations of any nature (whether accrued, absolute, contingent or
         otherwise) that would be required to be reflected on a balance sheet,
         or in the notes thereto, prepared in accordance with generally accepted
         accounting principles, except (i) for liabilities or obligations
         incurred in the ordinary course of business since the Bancshares Latest
         Statement Date that would not, individually or in the aggregate, have a
         Bancshares Material Adverse Effect; or (ii) as otherwise reflected in
         the Bancshares Reports (as defined below) filed prior to the date of
         this Agreement. Except as disclosed in the Bancshares Disclosure
         Letter, neither Bancshares nor Liberty has any liabilities or
         obligations of any nature (whether accrued, absolute, contingent or
         otherwise) that are not required to be reflected on a balance sheet, or
         in the notes thereto, except for liabilities or obligations that do
         not, individually or in the aggregate, have a Bancshares Material
         Adverse Effect.

                 (c)   Without limitation to the foregoing, Bancshares'
         consolidated allowance for the losses on loans included in the
         Bancshares Financial Statements as of March 31, 1998 was $573,800.00.
         To the knowledge of Bancshares, the amount of such allowance for losses
         on loans was adequate to absorb reasonably expectable losses in the
         loan portfolio of Liberty. To the knowledge of Bancshares, there are no
         facts which would cause it to increase the level of such allowance for
         losses on loans. To the knowledge of Bancshares, the documentation
         relating to loans made by Liberty and relating to all security
         interests, mortgages and other liens with respect to all collateral for
         such loans, taken as a whole, is adequate for the enforcement of the
         material terms of such loans and of the related security interests,
         mortgages and other liens, except 



                                       25
<PAGE>   197

         as enforcement may be limited by bankruptcy or similar laws or
         principles of equity. To the knowledge of Bancshares, the terms of such
         loans and of the related security interests, mortgages and other liens
         comply in all material respects with all applicable laws, rules and
         regulations (including laws, rules and regulations relating to the
         extension of credit). Except as set forth in the Bancshares Disclosure
         Letter, (i) as of March 31, 1998, there are no loans, leases, other
         extensions of credit or commitments to extend credit of Liberty that
         have been or should be, in accordance with generally acceptable
         accounting principles, classified by Liberty as non-accrual, as
         restructured, as ninety (90) days past due, as still accruing and
         doubtful of collection or any comparable classification; and (ii)
         Bancshares has provided to Sac River true, correct and complete in all
         material respects such written information concerning the loan
         portfolios of Liberty as Sac River has requested. Notwithstanding any
         provision in this Section 5.5(c) to the contrary, Liberty makes no
         representation or warranty with respect to the collectability of any
         loan.

         5.6     Reports. Bancshares and Liberty have filed all reports
registrations and statements, together with any amendments required to be made
with respect thereto, that were and are required to be filed with (i) the
Federal Reserve Board (i) the Division of Finance, (iii) the FDIC and (iv) any
other applicable federal or state banking authorities (all such reports and
statements are collectively referred to herein as the "Bancshares Reports"). As
of their respective dates, the Bancshares Reports filed prior to the date hereof
complied and will comply in all material respects with all of the statutes,
rules and regulations enforced or promulgated by the regulatory authority with
which they were filed, and did not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under
which they were made, not misleading.

         5.7     Authorizations; Compliance with Applicable Laws.

                 (a)   Bancshares and the Liberty hold all authorizations,
         permits, licenses, variances, exemptions, orders and approvals of all
         governmental entities which are material to the operation of the
         businesses of Bancshares and Liberty taken as a whole (the "Bancshares
         Permits"). All such Bancshares Permits are in full force and effect as
         of the Closing Date, and Bancshares and Liberty are in compliance with
         the terms of the Bancshares Permits, except where the failure so to
         comply could not reasonably be expected to have a Bancshares Material
         Adverse Effect. Except as disclosed in the Bancshares Reports filed
         prior to the date of this Agreement or the Bancshares Disclosure
         Letter, the businesses of Bancshares and Liberty are not being
         conducted in violation of any Laws, except for 



                                       26
<PAGE>   198

         possible violations which individually or in the aggregate do not, and,
         insofar as reasonably can be foreseen, in the future will not, have a
         Bancshares Material Adverse Effect. Except as set forth in the
         Bancshares Disclosure Letter, as of the date hereof, no investigation
         or review by a governmental entity with respect to Bancshares or to
         Liberty that would cause a Bancshares Material Adverse Effect is
         pending or, to the knowledge of Bancshares, threatened, nor has any
         governmental entity indicated an intention to conduct the same. The
         deposits of Liberty are insured by the FDIC to the extent provided by
         law.

                 (b)   The Bancshares Disclosure Letter identifies each parcel
         of real estate currently owned, leased or otherwise possessed or
         controlled by Bancshares or Liberty on the date of this Agreement,
         including real estate owned as a result of foreclosure and properties
         managed/or controlled by Liberty in connection with its lending or
         fiduciary obligations (collectively the "Bancshares Property"). Except
         as set forth in the Bancshares Disclosure Letter, to Bancshares'
         knowledge, none of the Bancshares Property owned or leased by them for
         use in the operation of their respective businesses is in violation of
         any applicable zoning ordinance or other law, regulation or
         requirements relating to the operation of any properties used,
         including, without limitation, applicable federal, state, and local
         laws, rules and regulations relating to the environment or to human
         health and safety associated with the environment (collectively
         "Environmental Laws"), other than violations that, in the aggregate
         with any other conditions described in this Section 5.7(b), would not
         have a Bancshares Material Adverse Effect; and neither Bancshares nor
         Liberty has receive any notice of any such violation, or the existence
         of any condemnation proceeding with respect to any Bancshares Property.
         Except as set forth in the Bancshares Disclosure Letter, to the
         knowledge of Bancshares, no Toxic Substances have been deposited or
         disposed of in, on or under any Bancshares Property during the period
         in which Bancshares or Liberty has owned, occupied, managed, controlled
         or operated such properties, except to the extent the same, in the
         aggregate with any other conditions described in this Section 5.7(b)
         would not have a Bancshares Material Adverse Effect. Except as set
         forth in the Bancshares Disclosure Letter, to Bancshares' knowledge, no
         portion of the Bancshares Property has ever been used as a dump or
         gasoline service station by any person, including past owners,
         occupants and operators of such properties. To the knowledge of
         Bancshares, there are no underground or above ground storage tanks
         (whether or not currently in use) located on or under the Bancshares
         Property, and no underground tanks previously located on the Bancshares
         Property has been removed therefrom. To the knowledge of Bancshares,
         there are no conditions or circumstances in connection with the
         Bancshares Property that 



                                       27
<PAGE>   199

         could reasonably be anticipated to (i) cause any Bancshares Property to
         be subject to any restrictions on ownership, occupancy, use or
         transferability under any applicable Environmental Laws; or (ii)
         materially reduce the value of any Bancshares Property. To the
         knowledge of Bancshares or Liberty, neither Bancshares nor Liberty has
         been identified as a potentially responsible party in a matter arising
         under any Environmental Laws.

         5.8     Litigation and Claims. Except as disclosed in the Bancshares
Reports filed prior the date of this Agreement or in the Bancshares Disclosure
Letter, (a) neither Bancshares nor Liberty nor any Bancshares Property is
subject to any continuing order of, or written agreement or memorandum of
understanding with any federal or state banking or insurance authority or other
governmental entity, or any judgment, order, writ, injunction, decree or award
of any governmental entity or arbitrator, including, without limitation,
cease-and-desist or other orders of any banking authority; (b) there is no
action, suit, litigation, proceeding or arbitration against or affecting
Bancshares or Liberty, to the knowledge of Bancshares, any directors, officers,
employees or agents of Bancshares or Liberty (in their respective capacities as
directors, officers, employees or agents) pending or, to the knowledge of
Bancshares, threatened, which would, if adversely determined, have a Bancshares
Material Adverse Effect or, to the knowledge of Bancshares, any basis therefor;
and (c) there are no uncured material violations, or violations with respect to
which material refunds or restitutions may be required, cited in any compliance
report to Bancshares or Liberty as a result of the examination of any bank
regulatory authority.

         5.9     Taxes. Bancshares and Liberty have filed all tax returns  
required to be filed by them and have paid or has set up an adequate reserve 
for the payment of all taxes required to be paid by them, except to the extent
which nonpayment did not result in a Bancshares Material Adverse Effect. The 
most recent Bancshares financial statements contained in the Bancshares Reports
reflect an adequate reserve for all taxes payable by Bancshares and Liberty
accrued to the date of such financial statements. The Bancshares Disclosure
Letter sets forth, as of the date hereof, the following information with respect
to Bancshares and Liberty: (a) whether there is an examination pending by the
IRS with respect to such corporation and, if so, the tax years involved; (b)
whether such corporation has executed or filed with the IRS any agreement which
is still in effect extending the period for assessment and collection of any
federal tax and, if so, the tax years covered by such agreement and the
expiration date of such extension; and (c) whether there are any existing
material disputes as to state or local taxes. There are no liens for taxes upon
the assets of Bancshares or Liberty, except for statutory liens for taxes not
yet delinquent or the validity of which is being contested in good faith by
appropriate proceedings and, in either case, only if 



                                       28
<PAGE>   200

adequate reserves therefor have been established on Bancshares' books in
accordance with generally accepted accounting principles. Except as disclosed in
the Bancshares Disclosure Letter, neither Bancshares nor Liberty is a party to
any action or proceeding by any governmental authority for assessment and
collection of taxes, and no claim for assessment and collection of taxes has
been asserted against any of them. Bancshares and Liberty have withheld from
their employees (and timely paid to the appropriate governmental agency) amounts
which are proper and accurate in all material respects for all periods through
the date hereof in material compliance with all tax withholding provisions of
applicable federal, state, and local laws (including without limitation income,
social security and employment tax withholding for all types of compensation).

         5.10    Certain Agreements. Except as discussed in the Bancshares
Reports filed prior to the date of this Agreement or as disclosed in the
Bancshares Disclosure Letter, and except for this Agreement and the agreements
expressly contemplated hereby, neither Bancshares nor Liberty is a party to any
oral or written (i) consulting or employment agreement or other agreement
providing any term of employment, compensation guarantee, or severance benefit,
(ii) union or collective bargaining agreement, (iii) agreement or plan,
including any stock option plan, stock appreciation right plan, restricted stock
option or stock purchase 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 contract, agreement or other instrument
or undertaking which is not terminable by Bancshares without additional payment
or penalty within sixty (60) days and obligates Bancshares or Liberty for
payments or other consideration for a value in excess of Ten Thousand Dollars
($10,000.00), other than loan agreements entered into in the ordinary course of
business, (v) contract, agreement or understanding to repurchase assets
previously sold (or to indemnify or otherwise compensate the purchaser in
respect to such assets) (other than repurchase agreements entered into in the
normal course of business); (vi) contract containing covenants which limit the
liability of Bancshares or Liberty 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, Bancshares or Liberty, as applicable, may carry on its
business (other than as may be required by law or applicable regulatory
authorities); or (vii) other executory material agreement. Except as set forth
in the Bancshares Disclosure Letter, neither Bancshares nor Liberty is in
Violation of any loan or credit agreement, note, mortgage, indenture or other
agreement, obligation or instrument applicable to Bancshares or Liberty or their
respective properties or assets, except for any such Violations that would not,
individually or in the aggregate, have a Bancshares Material Adverse Effect.

                 (a)   The Bancshares  Disclosure  Letter lists (i) each 
         employee bonus, incentive, deferred compensation, stock purchase, stock
         appreciation right, stock option, fringe benefit and severance pay
         plan, (ii) each pension, profit sharing, stock bonus, thrift, savings
         and employee stock ownership plan, (iii) each health, welfare,
         disability, vacation, leave, perquisite or executive plan, program,

         the meaning of Section three (3) of the Employee Retirement Income
         Security Act of 1974, as amended ("ERISA")) (collectively "Bancshares
         Benefit Plans") which Bancshares or Liberty maintains or to which
         Bancshares or Liberty contributes on behalf of current or former
         employees. Except as disclosed in the Bancshares Disclosure Letter, to
         the knowledge of Bancshares, all of the Bancshares Benefit Plans listed
         in the Bancshares Disclosure Letter comply with all applicable
         requirements of the Internal Revenue Code, ERISA and all other
         applicable federal and state laws and regulations, including, without
         limitation, the reporting and disclosure requirements of ERISA. Each of
         the Bancshares Benefit Plans which is intended to be a pension, profit
         sharing, stock bonus, thrift, savings or employee stock ownership plan
         that is qualified under Code Section 401(a) has been determined by the
         IRS who so qualify under Code Section 401(a), and, except as disclosed
         in the Bancshares Disclosure Letter, to the knowledge of Bancshares,
         there exists no circumstances that would adversely affect the qualified
         status of any such Bancshares Benefit Plan under that Section. Except
         as set forth in the Bancshares Disclosure Letter, there is no pending
         or, to the knowledge of Bancshares, threatened litigation, governmental
         proceeding or investigation against or relating to any Bancshares
         Benefit Plan, and to the knowledge of Bancshares there is no reasonable
         basis for any material proceedings, claims, actions or proceedings
         against Bancshares, Liberty, any Bancshares Benefit Plan, or any
         fiduciary of any Bancshares Benefit Plan. Except as set forth in the
         Bancshares Disclosure Letter, neither Bancshares, Liberty nor any party
         in interest (as defined in Section 3(14) of ERISA and Code Section
         4975(e)) nor any Bancshares Benefit Plan has engaged in a "prohibited
         transaction" (as defined in Section 406 of ERISA and Code Section
         4975(c)), and no Bancshares Benefit Plan has engaged in a transaction
         involving the purchase or sale of employer securities by such Plan from
         or to a "disqualified person" (within the meaning of Code Section
         4975), other than pursuant to an exemption provided therein. All
         Bancshares Benefit Plans that are group health plans, within the
         meaning of Code Section 4980B or Section 601 of ERISA, have been
         operated in material compliance with the group health plan continuation
         coverage requirements of Code 



                                       30
<PAGE>   202

         Section 4980B and Section 601 of ERISA to the extent such requirements
         are applicable.

                 (b)   There has been no amendment to, written interpretation
         of, or announcement (whether or not written) relating to, or any change
         in employee participation or coverage under, any Bancshares Benefit
         Plan that is not reflected in the text of the Bancshares Benefit Plan
         which would materially increase the expense (whether or not such
         expense is recognized under generally accepted accounting principles)
         to the employer whose employees are covered by such Bancshares Benefit
         Plan. Except as expressly provided by applicable law where the terms of
         a Bancshares Benefit Plan, no condition exists that would prevent the
         amendment or termination of any Bancshares Benefit Plan with respect to
         any employee. All employee and employer contributions with respect to
         employees which are due and owing as of the Closing Date pursuant to
         the Bancshares Benefit Plans have been made or will be accrued on the
         Closing Date Financial Statements and, except for such accrued
         liabilities, there are as of the Closing Date no other liabilities of
         Bancshares or Liberty with respect to the Bancshares Benefit Plans.

                 (c)   Bancshares has delivered to Sac River copies of (i) each
         Bancshares Benefit Plan or if no plan document exists, a written
         summary of the material terms thereof, (ii) current summary plan
         descriptions of each Bancshares Benefit Plan for which they are
         required, (iii) each trust agreement, insurance policy or other
         instrument relating to the funding of any Bancshares Benefit Plan, (iv)
         the most recent Annual Reports (Form 5500 Series) and accompanying
         schedules filed with the IRS or the United States Department of Labor
         with respect to each Bancshares Benefit Plan for which they are
         required, (v) the most recent determination letter issued by the IRS
         with respect to each Bancshares Benefit Plan that is intended to
         qualify under Code Section 401, (vi) the most recent available
         financial statements for each Bancshares Benefit Plan that has assets,
         and (vii) the most recent audited financial statements for each
         Bancshares Benefit Plan for which audited financial statements are
         required by ERISA.

                 (d)   The Bancshares Disclosure Letter describes any obligation
         that Bancshares or Liberty has to provide health and welfare benefits
         to retirees or other former employees or their dependents (other than
         rights arising solely under Section 601 of ERISA or Code Section 4980B)
         including information as to the number of retirees, other former
         employees and dependents entitled to such coverage and their ages.

         5.12    Insurance. Bancshares and Liberty are presently insured for
reasonable amounts with financially sound and reputable 



                                       31

insurance companies against such risks as, to the knowledge of Bancshares,
companies engaged in a similar business would, in accordance with good business
practice, customarily be insured. Neither Bancshares nor Liberty has any
liability for material unpaid premiums or premium adjustments not properly
reflected on the Bancshares Financial Statements and no notice of cancellation
or termination has been received by Bancshares or Liberty with respect to any
material insurance policy currently in effect. Except as disclosed in the
Bancshares Disclosure Letter, neither Bancshares nor Liberty has been refused
any insurance with respect to any assets or operations, nor has any coverage
been limited in any material respect as to any assets or operations, by any
insurance carrier to which it has applied for any such insurance or with which
it has carried insurance.

         5.13    Absence of Certain Changes or Events. Except as disclosed in

<PAGE>   204

destruction or loss as a result of fire, accident, casualty, labor trouble, or
taking of property by any government or any agency of any government, flood, or
other similar or dissimilar casualty or event or otherwise, and whether or not
covered by insurance (k) neither Bancshares nor Liberty has cancelled or

nor Liberty has entered, or agreed to enter, into any agreement or arrangement
granting any right of refusal or other preferential right to purchase any of its

(n) there has not been any transaction, commitment, dispute or other event or
condition of any character (whether or not in the ordinary course of business)
individually or in the aggregate having or which, insofar as reasonably can be
foreseen, in the future is reasonably likely to have, a Bancshares Material
Adverse Effect (m) there has not been any material change in the method of
accounting or accounting practices of Bancshares and Liberty, except as required
by law or generally accepted accounting principles. Except as set forth in the
Bancshares Disclosure Letter, Bancshares has no knowledge of the announced or
anticipated resignation of any executive officer or key employee of Bancshares
or Liberty. From and after the date of the latest Bancshares Financial
Statement, through the date of this Agreement, no customers of Liberty have
indicated to Liberty that they will stop or decrease the rate of business done
with Liberty (except for changes in the ordinary course of business) such as to,
individually or in the aggregate, have a Bancshares Material Adverse Effect.

         5.14    Properties, Leases and Other Agreements. Except as may be
reflected in the Bancshares Financial Statements, for any lien for current taxes
not yet delinquent, for pledges to secure deposits and for such other liens,
security interests, claims, charges, options or other encumbrances and
imperfections of title which do not materially affect the value of personal or
real property reflected in the Bancshares Financial Statements or acquired since
the date of such Financial Statements and which do not materially interfere with
or impair the present and continued use of such property, Bancshares and Liberty
have good title, free and clear of any liens, security interests, claims, 
charges, options or other encumbrances, to all of the personal and real property
reflected in the Bancshares Financial Statements, and all personal and real
property acquired since the date of such Statements, except such personal and
real property as has been disposed of in the ordinary  course of business.  The
Bancshares Disclosure Letter lists all acquisitions or dispositions of capital
assets planned as of the date of this Agreement by Bancshares or Liberty, other
than individual transactions with a value not in excess of $50,000.00 each.
Substantially all Bancshares' and 



                                       33
<PAGE>   205

Liberty's buildings and equipment in regular use (including such buildings and
equipment as are leased) have been well maintained and are in good and
serviceable condition, reasonable wear and tear excepted. The Bancshares
Disclosure Letter contains a brief description, including terms, of each lease
for real or personal property to which Bancshares or Liberty is a party.
Bancshares or Liberty, as lessee, has a valid and existing leasehold interest
under each of such leases, true and correct copies of which Bancshares has
delivered to Sac River. There is not, under any of such leases relating to real
property or any other material leases, any material existing default by
Bancshares, Liberty or, to the knowledge of Bancshares, any other party thereto,
or any event with notice or lapse of time or both would constitute such a
material default.

         5.15    Vote Required. The affirmative vote of holders of two-thirds
(2/3) fof the  outstanding  shares  of  Liberty  common  stock is the only 
vote of the holders of Liberty  common  stock  necessary  to approve the 
Agreement  and the transactions contemplated hereby.

         5.16    Tax Matters. To the knowledge of Bancshares, neither Bancshares
nor any of its  affiliates  has through the date hereof  taken or agreed to take
any  action  that  would  prevent  the  Merger  from  qualifying  as one or more
reorganizations under Code Section 368(a)(1).

         5.17    Regulatory Impediments. As of the date hereof, Bancshares is
unaware of the existence of any factor that would materially delay or materially
hinder the issuance of any of the  required  regulatory  approvals  necessary to
consummate the Merger or the other transactions  contemplated hereby, other than
any protests by an nongovernmental parties.

         5.18    Full Disclosure. The representations and warranties of
Bancshares contained in this Agreement do not omit any material fact necessary
to make the statements contained therein, in light of the circumstances under
which they were made, not misleading. There is no fact known to Bancshares which
has not been disclosed to Sac River pursuant to this Agreement, the Bancshares
Disclosure Letter and the Bancshares Reports, all taken together as a whole,
which would reasonably be expected to have a Bancshares Material Adverse Effect
or a material adverse effect on the ability of Bancshares or Sac River to
consummate the transactions contemplated hereby.

                                   ARTICLE VI

         rights and franchises, and use its reasonable best efforts to retain

         future will not, have a Sac River Material Adverse Effect.

         6.2     Negative Covenants. Except as specifically contemplated by this
Agreement, from the date hereof unto the Effective Time, Sac River shall not do,
without the prior written consent of Bancshares (which shall not be unreasonably

<PAGE>   209

         either in default or classified, whether such classification is a
         result of a federal or state bank regulatory examination or internal
         classification of substandard or lower by Sac River's officers or
         directors, unless Sac River is under a legal obligation to do so. With
         respect to any Bancshares consent required by this Section 6.2(l),
         Bancshares shall provide advice of its consent within three business
         days after Bancshares has received the request for consent and

in which Bancshares may have a reasonable interest, including without
limitation, its interest in planning for integration and transition with
respect to the business of Sac River. During such period, Sac River will cause
one or more of its representatives to confer on a regular and frequent basis
with representatives of Liberty, to report on the general status of its ongoing
operations and to consult as to the making of any decisions or the taking of
any actions in matters other than in the ordinary course of business. During

after such documents are available, (ii) the monthly financial statements of

reasonable notice by Bancshares to such individuals, and to cooperate fully with
Bancshares in planning for the integration of the business of Sac River with the
business of Bancshares and Liberty.

                 (a)   From and after the date hereof until the Effective Time,
         Sac River shall promptly, but not less frequently than monthly, update
         the Sac River Disclosure Letter by notice to Bancshares to reflect any
         matters which have occurred from and after the date hereof which, if
         existing on the date hereof, would have been required to be described
         therein; provided, however, that no such update shall affect the
         conditions to the obligation of Bancshares to consummate the
         transactions contemplated hereby, except as provided herein, and any
         and all changes reflected in any such update shall be considered in
         determining whether such conditions have been satisfied.

                 (b)   Sac River shall, in the event it becomes aware of the

         would cause or constitute a material breach (or would have caused or
         constituted a breach had such even occurred or been known prior to the
         date hereof) of any of its representations or agreements contained or
         referred to herein of which would cause any of the conditions to the
         obligations of any party set forth in Article IX hereof not to be

         best efforts to prevent or promptly remedy the same.

         (2) would result in the aggregate indebtedness of said borrower to be

                                       43
<PAGE>   215

         substandard or lower by Liberty's officers or directors, unless Liberty
         is under a legal obligation to do so. With respect to any Sac River
         consent required by this Section 7.2(l), Sac River shall provide advice
         of its consent within three business days after Sac River has received
         the request for consent and accompanying information necessary for Sac
         River to consider the request (the provisions of part A of this section
         shall not apply to renewals of existing loans, advances under existing
         loans or increases to existing loans for an amount below the applicable
         limits set forth in part A);

                 (m)   purchase any equity securities not in the ordinary course
         of business; or

                 (n)   agree in writing or otherwise to do any of the foregoing.

         7.3     Access and Information. Except where prohibited by law, upon
reasonable prior notice Bancshares shall ( and shall cause Liberty to) afford to
Sac River's officers, employees, accountants, counsel and other representatives,
access, from time to time during normal business hours during the period prior
to the Effective Time, to all books, papers and records relating to the assets,
stock, properties, operations, obligations and liabilities of Bancshares and
Liberty, including without limitation all books of account tax records, minute
books of directors' and stockholders' meetings, contracts and agreements,
filings with any regulatory authority, accountants' work papers, litigation
files (other than attorney work product or materials protected by any
attorney-client privilege), documents relating to assets and title thereto,
plans affecting employees, securities transfer records and stockholder lists,
and any books, papers and records relating to other assets, business activities
or prospects in which Sac River may have a reasonable interest. During such
period, Bancshares will cause one or more of its representatives to confer on a
regular and frequent basis with representatives of Sac River, to report on the
general status of its ongoing operations and to consult as to the making of any
decision or the taking of any actions in matters other than in the ordinary
course of business. During such period, Bancshares shall (and shall cause
Liberty to), except where prohibited by law, furnish promptly to Sac River (i) a
copy of each Bancshares 



                                       44
<PAGE>   216

Report filed or received by it during such period pursuant to the requirements
of the BHC Act and any other federal or state banking laws promptly after such
documents are available; (ii) the monthly financial statements of Bancshares and
Liberty (as prepared by Bancshares in accordance with its normal accounting
procedures) promptly after such financial statements are available; (iii) a
summary of any action taken by the Board of Directors, or any committee thereof,
of Bancshares; (iv) minutes of the Bancshares Board of Directors meetings and
the reports of management of Bancshares and Liberty customarily provided to
their respective Boards of Directors; and (v) all other information concerning
its business, properties and personnel as Sac River may reasonably request.
During such period, Bancshares shall, and shall cause Liberty to, instruct its
officers, employees, counsel and accountants to be available for, and respond to
any questions of, Sac River's officers, employees, accountants, counsel and
other representatives at reasonable hours and with reasonable notice by Sac
River to such individuals, and to cooperate fully with Sac River in planning for
the integration of the business of Sac River with the business of Bancshares and
Liberty.

         7.4     Update Disclosure; Breaches.

                 (a)   From and after the date hereof until the Effective Time,
         Bancshares shall promptly, but not less frequently than monthly, update
         the Bancshares Disclosure Letter by notice to Sac River to reflect any
         matters which have occurred from and after the date hereof which, if
         existing on the date hereof, would have been required to be described
         therein; provided, however, that no such update shall affect the
         conditions to the obligation of Sac River to consummate the
         transactions contemplated hereby, except as provided herein, and any
         and all changes reflected in any such update shall be considered in
         determining whether such conditions have been satisfied.

                 (b)   Bancshares shall, in the event it becomes aware of the
         impending or threatened occurrence of any event or condition which
         would cause or constitute a material breach (or would have caused or
         constituted a breach had such event occurred or been known prior to the
         date hereof) of any of its representations or agreements contained or
         referred to herein or which would cause any of the conditions to the
         obligations of any party set forth in Article IX to be satisfied, give
         prompt written notice thereof to Sac River and use its best efforts to
         prevent or promptly remedy the same.

         7.5     Liberty Benefit Plans. Liberty shall provide to retained
employees of Sac River all corporate-wide employee retirement, health, dental,
life and long-term disability benefits that Liberty provides to its similarly
situated employees, subject to the age and eligibility requirements for such
benefits. Each such employee's last continuous period of service prior to the
Effective 



                                       45
<PAGE>   217

Time with Sac River shall count for purposes of determining eligibility and
vesting for all such benefits. If such coverage under the Liberty benefits is
not provided immediately after the Effective Time, Liberty shall continue the
Sac River plans until coverage is effective under Liberty's plans so that no
lapse in benefits occurs. Without limiting the generality of the foregoing, no
preexisting condition limits shall be applied to participants in Benefit Plans
upon their eligibility for such Liberty benefits (except for continuation of any
such limits that were in effect under the applicable Benefit Plans). For the
purpose of determining each employees's benefit for the year in which the Merger
occurs under the Liberty vacation program, vacation taken by an employee in the
year in which the Merger occurs will be deducted from the total Liberty benefit.

         7.6     Tax Treatment. Bancshares will use its best efforts to cause
the Merger to qualify as one or more reorganizations under Code ss.368(a)(1).
Following the Merger, Bancshares and Liberty will not take any action the effect
of which will prevent the Merger from qualifying as one or more reorganizations
under Code Section 368(a)(1).

                                  ARTICLE VIII
                              ADDITIONAL AGREEMENTS

         8.1     Filings and Approvals.

                 (a)   Each party will use all reasonable efforts and will
         cooperate with the other in the preparation and filing, as soon as
         practicable, of all applications or other documents required to obtain
         the requisite approvals of and consents to the Merger and other
         transactions contemplated by this Agreement, from the Federal Reserve
         Board, the Division of Finance and the FDIC as applicable, and from any
         other applicable bank regulatory authorities and provide copies of
         nonconfidential portions of such applications, filings and related
         correspondence to the other parties. Prior to filing each application,
         notice or other documents with the applicable regulatory authority,
         each party will provide the other party with an opportunity to review
         and comment on the nonconfidential portions of each such application,
         notice or other document. Each party shall ensure that none of the
         information supplied or to be supplied by it for inclusion or
         incorporation by reference in any documents to be filed with the
         Federal Reserve Board, the Division of Finance, the FDIC or any other
         regulatory agency in connection with the transactions contemplated
         hereby will, at the time of filing, contain any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein. Subject to the terms and conditions herein provided, each
         party will use all reasonable efforts to take, or cause to be taken,
         all actions and to do, or cause to be done, all things necessary,

                                       46
<PAGE>   218

         proper or advisable to cause the conditions herein provided, each party
         will use all reasonable efforts to take, or cause to be taken, all
         actions and to do, or cause to be done, all things necessary, proper or
         advisable to cause the conditions set forth in Article IX to be
         satisfied, including participating in any required hearings or
         proceedings, and to consummate and make effective as promptly as
         practicable the transactions contemplated by this Agreement. Each party
         shall keep the other advised of all material regulatory developments in
         a timely manner.

                 (b)   In the event of a restraining order or injunction which
         prevents the Closing by reason of the operation of Section 9.1(a), Sac
         River and Bancshares shall use their respective best efforts to cause
         such order or injunction to be lifted and the Closing to be consummated
         as soon as reasonably practicable.

         8.2     Registration Statement.

                 (a)   For the purposes of (i) holding a meeting of the
         stockholders of Sac River to approve this Agreement and the Merger (the
         "Meeting") and (ii) registering the Bancshares common stock to be
         issued to holders of Sac River common stock in connection with the
         Merger with the Securities and Exchange Commission (the "SEC") and with
         applicable state securities authorities, the parties hereto shall
         cooperate in the preparation of an appropriate registration statement
         (such registration statement, together with all and any amendments and
         supplements thereto, being herein referred to as the "S-4"), which
         shall include a joint prospectus of Bancshares and proxy statement of
         Sac River (the "Proxy Statement") that shall satisfy all applicable
         requirements of the Securities Act, the Exchange Act, applicable state
         securities laws and the rules and regulations thereunder.

                 (b)   Bancshares shall furnish such information concerning
         Bancshares as is necessary in order to cause the Proxy Statement,
         insofar as it relates to Bancshares to be prepared in accordance with
         Section 8.2(a) hereof. Bancshares agrees promptly to advise Sac River
         if any time prior to the Meeting any information provided by Bancshares
         in the Proxy Statement becomes incorrect or incomplete in any material
         respect, and to provide the information needed to correct such
         inaccuracy or omission. At the time the S-4 becomes effective and at
         the time the Proxy Statement is mailed to the shareholders of Sac River
         and at all times subsequent to such mailing up to and including the
         time of the Meeting, the S-4 and such Proxy Statement (including any
         amendments or supplements thereto), with respect to all information set
         forth therein relating to Bancshares (including Liberty) and the
         Bancshares common stock, this Agreement, the Merger and all other
         transactions 

                                       47
<PAGE>   219

         contemplated hereby, will (a) comply in all material respects with
         applicable provisions of the Securities Act and the Exchange Act, and
         (b) not contain any untrue statement of material fact or omit to state
         a material fact required to be stated therein or necessary to make the
         statements contained therein, in light of the circumstances under which
         they are made, not misleading.

                  (b) Each issued and outstanding share of Sac River common
         stock issued and outstanding after the Effective Date shall cease to be
         outstanding, and shall be automatically cancelled and retired and shall
         cease to exist, and shall be converted into and exchanged for the right

                  River, with respect to each share of Sac River common stock:

                                    (A) Cash in the amount of One Thousand Fifty
                           Dollars ($1,050.00) per share (the "Optional Per
                           Share Cash Amount"); provided, however, that the
                           total cash payable by Bancshares with respect to the
                           Optional Per Share Cash Amount to all shareholders of

common stock issued and outstanding prior to the Effective Date as a result of a
stock split, stock dividend, or similar recapitalization with respect to such
stock and the record date therefore (in the case of a stock dividend) or the
effective date thereof (in the case of a stock split or similar recapitalization
for which a record date is not established) shall be prior to the Effective
Date, the Exchange Ratio shall be proportionately adjusted.

         2.3 Notwithstanding any other provision of this Agreement, each holder
of shares of Sac River common stock exchanged pursuant to the Merger who would
otherwise have been entitled to receive a fraction of a share of Bancshares
common stock (after taking into account all certificates delivered by such
holder) shall receive, in lieu thereof, cash (without interest) in an amount
equal to such fractional part of a shares of Bancshares common stock multiplied
by the value of one share of Bancshares common stock at the Effective Date. For
purposes of this Agreement, the value of one share of Bancshares common stock at
the Effective Date shall be $29.56 (subject to adjustment as provided in Section
2.2 hereof). No such holder shall be entitled to dividends, voting rights, or
any other rights as a shareholder in respect of any fractional shares.

         2.4 Elections by shareholders of Sac River to receive Optional Per
Share Cash Amounts shall be made by mailing or delivering to the Exchange Agent
(as defined below) the Form of Election delivered to the shareholders of Sac
River with the Proxy Statement (as defined in the Reorganization Agreement). To

of Election with the Proxy Statement to all holders of Sac River common stock on
the record date of the Sac River special shareholders' meeting and shall make
the Form of Election available to all persons who become holders of Sac River
common stock subsequent to such day and no later than the close of business on
the business day prior to the Extended Election Deadline. All elections by
shareholders to receive Optional Per Share Cash Amounts may be revoked or
amended until the Extended Election Deadline. If no such election is filed by a
Sac River shareholder, no Optional Per Share Cash Amount shall be made to the
shareholder, and all of the Sac River shares held by the shareholder shall be
exchanged for Bancshares common stock in accordance with the Exchange Ratio
(except for the Mandatory Per Share Cash Amount). Each Sac River shareholder who
does not vote in favor of the Merger as of the Extended Election Deadline shall
be deemed, subject to the right hereinabove provided for amendment or revocation
of the election and subject to the provisions of Section 2.9 hereof, to have
made an election to receive Optional Per Share Cash Amounts with respect to his
or her shares, regardless of the actual Form of Election submitted by said
shareholder

         2.5 At the closing of the Merger (the "Closing" or "Closing Date"),
Bancshares shall deposit with Husch & Eppenberger, LLC (the "Exchange Agent"),
for the benefit of the then holders of shares of Sac River common stock,
certificates dated as of the Closing Date representing the shares of Bancshares
common stock, the cash to be paid in lieu of fractional shares, the Optional Per
Share Cash Amounts (if any), and the Mandatory Per Share Cash Amounts (such cash
and certificates of Bancshares common stock, together with any dividend or
distributions with respect thereto, being hereinafter referred to as the
"Exchange Fund") to be issued and paid pursuant to Section 2.1 hereof in
exchange for the outstanding shares of Sac River common stock. Within five (5)
business days after the Closing Date, Bancshares shall cause the Exchange Agent
to mail to each holder of record as of the Closing Date of a Sac River
certificate or certificates (i) a letter of transmittal which will specify that
delivery shall be effective, and risk of loss and title to the Sac River
certificate(s) shall pass, only upon delivery of the Sac River certificate(s) to
the Exchange Agent and which shall be in such form and have such other
provisions as Bancshares and Sac River may reasonably specify, and (ii)
instructions for use in effecting the surrender of the Sac River certificate(s)
in exchange for a certificate representing shares of Bancshares common stock,
cash to be paid in lieu of any fractional share, the Optional Per Share Cash
Amount (if any) and the Mandatory Per Share Cash Amount. Upon surrender of a
shareholder's Sac River certificate or certificates for cancellation to the
Exchange Agent together with such letter of transmittal, duly


                                        5

executed, the holder of such Sac River certificate(s) shall be entitled to
receive in exchange therefore, within ten (10) business days following said
surrender, (1) a certificate representing the applicable number of whole shares
of Bancshares common stock, and (2) a check representing the amount of the cash
to be paid in lieu of a fractional share, if any, the Optional Per Share Cash
Amount (if any) and the Mandatory Per Share Cash Amount, and the Sac River
certificate(s) so surrendered shall forthwith be cancelled; provided, however,
that any Sac River shareholder who does not vote in favor of the Merger shall
not be entitled to receive said cash earlier than sixty (60) days after the
Effective Date. Except for said shareholders (who, except as provided in Section
2.9 hereof, shall receive interest at the rate of 9% per annum during the period
of sixty (60) days following the Effective Date), no interest will be paid on
the cash in lieu of fractional shares, if any, the Optional Per Share Cash
Amount (if any), and the Mandatory Per Share Cash Amount. Any applicable stock
transfer taxes shall be paid by Bancshares. Adoption of this Agreement by the
shareholders of Sac River and Liberty shall constitute ratification of the
appointment of the Exchange Agent.

         2.6 At the Effective Date, the stock transfer books of Sac River shall
be closed as to holders of Sac River common stock immediately prior to the
Effective Time and no transfer of Sac River common stock by any such holder
shall thereafter be made or recognized. Until surrendered for exchange in
accordance with the provisions of Section 2.5 hereof, each certificate
theretofore representing shares of Sac River common stock shall from and after
the Effective Time represent for all purposes only the right to receive the
consideration provided in Section 2.1 hereof in exchange therefore, subject,
however, to Bancshares' obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Date which have been
declared or made by Sac River in respect of such shares of Sac River common
stock in accordance with the terms of this Agreement and which remain unpaid at
the Effective Date. Whenever a dividend or other distribution is declared by
Bancshares on the Bancshares common stock, the record date for which is at or
after the Effective Date, the declaration shall include dividends or other
distributions on all shares of Bancshares common stock issuable pursuant to this
Agreement, but beginning thirty (30) days after the Effective Date no dividend
or other distribution payable to the holders of record of Bancshares common
stock as of any time subsequent to the Effective Date shall be delivered to the
holder of any certificate representing shares of Sac River common stock issued
and outstanding at the Effective Date until such holder surrenders such
certificate (or an affidavit in lieu thereof pursuant to Section 2.8 hereof) for
exchange as provided in Section 2.5 of this Agreement. However, upon surrender
of Sac River common stock certificate, both the Bancshares common stock
certificate (together with all such undelivered dividends or other distributions
without interest) and any undelivered dividends and cash payments payable


                                        6

<PAGE>   238



thereunder (without interest) shall be delivered and paid with respect to each
share represented by such certificate.

         2.7 Any portion of the Exchange Fund that remains unclaimed by the
shareholders of Sac River for twelve (12) months after the Closing Date shall be
paid to Bancshares. Any shareholders of Sac River who have not theretofore
complied with this Article II shall thereafter look only to Bancshares for
payment of their shares of Bancshares common stock, cash in lieu of any
fractional share of Bancshares common stock, Optional Per Share Cash Amount (if
any) and Mandatory Per Share Cash Amount, without any interest thereon.
Notwithstanding the foregoing, neither the Exchange Agent nor Bancshares shall
be liable to any former holder of shares of Sac River common stock for any
amount properly delivered to a public official pursuant to any applicable
abandoned property, escheat or similar laws.

         2.8 In the event any Sac River certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Sac River certificate to be lost, stolen or destroyed and, if
required by the Exchange Agent, the execution and delivery of an indemnity
agreement whereby said person shall agree to indemnify the Exchange Agent and
Bancshares against any claim which may be made against it with respect to such
Sac River certificate, the Exchange Agent will issue in exchange for such lost,
stolen or destroyed Sac River certificate the shares of Bancshares common stock
and cash in an amount as determined in accordance with Section 2.1 hereof,
deliverable in respect thereof pursuant to this Agreement.

         2.9 Each issued and outstanding share of Sac River common stock, the
holder of which has validly asserted dissenters' rights pursuant to RSMo.
Section 362.730 and has not effectively withdrawn or lost such rights, shall 
not be converted into or represent a right to receive the consideration 
specified in Section 2.1 hereof, but the holder thereof shall be entitled only
to such rights as are granted by RSMo. Section 362.730. In the event the holder
of Sac River common stock validly asserts dissenters' pursuant to RSMo.
Section 362.730, any cash held by the Exchange Agent with respect to said
shareholder's shares shall be paid by the Exchange Agent to the Surviving
Association. Each shareholder entitled, pursuant to the provisions of RSMo.
Section 362.730, to payment for his or her shares of Sac River common stock, 
shall receive payment therefore from the Surviving Association (but only after 
the amount thereof shall have been agreed upon or determined pursuant to such
provisions) and such shares of Sac River common stock shall be cancelled. If
any holder of shares of Sac River common stock who asserts dissenters' rights
under RSMo. Section 362.730 effectively withdraws or loses (through failure to
perfect or otherwise) such rights, each such share of Sac River common stock
shall be converted into the right to receive the consideration specified in
Section 2.1 hereof.

       RE:      Agreement and Plan of Merger, Dated as of June 18, 1998, among 
                Sac River Valley Bank, Liberty Bancshares, Inc. and Liberty Bank

Ladies and Gentlemen:

         We have acted as counsel for Liberty Bank ("Liberty") and Liberty
Bancshares, Inc. ("Bancshares") in connection with the proposed merger (the
"Merger") of Sac River Valley Bank ("Sac River") with and into Liberty, pursuant
to the terms of the above-referenced agreement (the "Agreement"). Liberty is the
wholly owned subsidiary of Bancshares. Unless otherwise defined herein, all
capitalized terms shall have the respective meetings set forth in the Agreement.

         We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion, including, but not limited to,
the current provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury Regulations promulgated thereunder, and applicable
judicial and administrative interpretations thereof, existing as of the date
hereof, any of which is subject to change at any time. We have also made the
following factual assumptions:

                  1.     The Merger will be consummated in accordance with the 
         terms of the Agreement.

                  2.     The representations and warranties of the parties under
         the Agreement will be true and correct in all material respects as of 
         the effective date of the Merger, except to the extent waived by the
         parties.

                  3.     As of the effective date of the Merger, there will be 
         no plan or intention on the part of Bancshares or any entity related to
         Bancshares to reacquire any of the shares of Bancshares common stock to
         be issued in the Merger.

                  4.     Bancshares will not terminate the Sac River Valley Bank
         Employee Stock Ownership Plan at any time sooner than one year
         following the effective date of the Merger.

                  5.     Bancshares will not have any call rights with respect 
         to the Bancshares stock to be received by the Sac River stockholders in
         the Merger.

                  6.     Except as may be provided in Article XI of the Sac 
         River Valley Bank Employee Stock Ownership Plan and Trust Agreement, no
         Sac River shareholder will have put rights with respect to any 
         Bancshares stock to be received in the Merger.

                  7.     Total cash consideration to Sac River shareholders in
         exchange for their Sac River common stock, including the reasonable
         cash value of shares of Sac River shareholders who exercise dissenters'
         rights granted under RSMo. Section 362.730 with respect to their Sac 
         River common stock (by applying in the appropriate court either before 
         or after the Merger by petition for the appointment of appraisers to 
         value said shares), as finally determined by a court of competent
         jurisdiction, shall not exceed, in the aggregate, $8,657,000.00.

                  8.     Liberty will acquire at least 90% of the fair market 
         value of the net assets and at least 70% of the fair market value of 
         the gross assets held by Sac River immediately prior the Merger.

                  9.     Prior to the Merger, Bancshares will own all of the 
         issued and outstanding shares of stock of Liberty.

                  10.    Following the Merger, Liberty will not issue additional
         shares of its stock that would result in Bancshares losing control of
         Liberty within the meaning of Code Section 368(c).

                  11.    As of the effective date of the Merger, Bancshares will
         have no plan or intention to liquidate Liberty; to merge Liberty with
         and into another corporation; to sell or otherwise dispose of the stock
         of Liberty; or to cause Liberty to sell or otherwise dispose of any of
         the operating assets of Sac River acquired in the Merger, except for
         dispositions made in the ordinary course of business or transfers
         described in Code Section 368(a)(2)(C).

                  12.    The liabilities of Sac River assumed by Liberty and the
         liabilities to which the transferred assets of Sac River are subject
         were incurred by Sac River in the ordinary course of its business.

                  13.    Following the Merger, Liberty will continue the 
         historic business of Sac River or use a significant portion of Sac 
         River's business assets in a business.

                  14.    Bancshares, Liberty, Sac River, and the shareholders of
         Sac River will pay their respective expenses, if any, incurred in
         connection with the Merger.

                  15.    There is no inter-corporate indebtedness existing 
         between Bancshares and Liberty or between Liberty and Sac River that 
         was issued, acquired or will be settled at a discount.

                  16.    The fair market value of the assets of Sac River
         transferred to Liberty will equal or exceed the sum of the liabilities
         assumed by Liberty, plus the amount of liabilities, if any, to which
         the transferred assets are subject.

                  17.    No stock of Liberty will be used in the Merger.

         Based upon the foregoing assumptions, and in reliance upon the matters
set forth above, and subject to the exceptions and qualifications contained
herein, we are of the opinion that, for federal income tax purposes:

                  1.     The Merger will constitute a "reorganization" within 
         the meaning of Code Section 368(a)(1)(A) and Code Section 368(a)(2)(D),
         and each of Bancshares, Liberty and Sac River will be a party to a
         reorganization within the meaning of Code Section 368(b).

                  2.     No gain or loss will be recognized by Bancshares, 
         Liberty, or Sac River as a result of the Merger.

                  3.     Sac River stockholders will not recognize any gain or 
         loss upon the receipt of Bancshares common stock (as opposed to cash) 
         in exchange for their Sac River common stock.

                  4.     The tax basis of the Bancshares common stock received 
         by a Sac River stockholder will be the same as the basis of the Sac 
         River common stock surrendered in exchange therefor reduced by the 
         portion of the basis allocable to the fractional shares of Bancshares 
         stock received in the Merger.

                  5.     The holding period for Bancshares stock received by Sac
         River stockholder in the Merger will include the period during which
         the Sac River common stock surrendered in exchange therefor was held.

                  6.     Each Sac River stockholder will recognize gain equal to
          the lesser of (i) the amount of cash received in the Merger or (ii) 
         the amount, if any, by which the sum of the cash plus the fair market 
         value of the Bancshares stock received in the Merger exceeds the
         stockholder's basis in the Sac River shares surrendered. For purposes
         of determining the character of such gain, the cash received in the
         Merger will be treated as if shares of Bancshares common stock equal in
         value to the cash had been distributed to the Sac River shareholders as
         part of the Merger and then immediately after the Merger such shares
         were redeemed by Bancshares. Depending upon the particular
         circumstances of each shareholder, such cash payments will be
         characterized as either having been received as a distribution in full
         payment in exchange for the Bancshares stock deemed to have been
         redeemed or as having been received as a dividend, as provided in Code
         Section 302. A cash payment will be treated as distribution in full 
         payment in exchange for the Bancshares stock if the deemed redemption 
         is "substantially disproportionate" within the meaning of Code Section
         302(b)(2), is in complete termination of the shareholder's interest in
         the corporation within the meaning of Code Section 302(b)(3), or is
         "not essentially equivalent to a dividend" within the meaning of Code
         Section 302(b)(1). A redemption is treated as "substantially
         disproportionate" if (1) the shareholder owns less than 50% of the
         total combined voting power of all classes of stock immediately after
         the redemption; (2) the ratio of the shareholders' holdings of voting
         stock immediately after the redemption to all the voting stock in the
         corporation at that time is less than 80% of the ratio which the voting
         stock the shareholder owned immediately before the redemption bore to
         the entire voting stock in the corporation at that time (the "80%
         test");

         and (3) the shareholders' ownership of common stock (whether voting or
         nonvoting) after and before the redemption also meets the 80% test. A
         redemption is treated as "not essentially equivalent to a dividend" if
         it results in a meaningful reduction of the shareholder's
         proportionate interest in the corporation. When making a determination
         as to whether a redemption is substantially disproportionate or not,
         essentially equivalent to a dividend, or, subject to certain
         exceptions, whether the redemption terminates the shareholder's entire
         interest in the corporation, the constructive ownership rules of Code
         Section 318 apply. If the cash payment is treated as having been
         received by a Sac River stockholder as a distribution in full payment
         in exchange for redeemed shares, such stockholder's gain recognized in
         the Merger will be short-term, mid-term or long-term capital gain,
         depending upon the Sac River stockholder's holding period for the Sac
         River stock. If the cash payment is treated as having been received by
         a Sac River stockholder as a dividend, the stockholder's gain on the
         Merger will be recognized as ordinary income.

         This opinion is subject to the following additional assumptions and
         qualifications:

                  (a)    This opinion is specifically limited to applicable 
         federal income tax laws in effect as of the date hereof.

                  (b)    We undertake no responsibility to advise you of any
         changes in the federal income tax law or as to any events that may
         occur or as to any amendment of any of the documents referred to
         herein, after the Closing of the Merger, that may alter the scope or
         substance of this opinion.

                  (c)    This opinion is based upon the assumption by management
         of Liberty and Bancshares (without independent verification by us) 
         that, to the best of management's knowledge and belief:

                           (i)     As of the effective date of the Merger, the 
                  fair market value of the Bancshares stock and other 
                  consideration to be received by each Sac River shareholder 
                  will be approximately equal to the fair market value of the 
                  Sac River stock surrendered in the Merger; and

                           (ii)    As of the effective date of the Merger, the 
                  fair market value of Bancshares common stock shall not be less
                  than $29.50 per share.

         This opinion may be specifically relied upon by the shareholders of Sac
         River.

362.730.  DISSENTING STOCKHOLDER MAY RECEIVE REASONABLE VALUE OF HIS STOCK-
            LIMITATION, PETITION, HEARING, APPOINTMENT OF APPRAISERS

1. If any merger or consolidation takes effect under the provisions of sections
362.610 to 362,810, then the holder of any stock, with or without voting rights,
of any corporation which is a party to the agreement not voting in favor of the
agreement to merge or consolidate at the stockholders' meeting aforesaid shall
be entitled to receive from the receiving corporation, in case of a merger or
from the consolidated corporation in case of a consolidation, the reasonable
value of his stock at the time of the merger or consolidation, which value shall
be determined in the following manner:

         (1) Within sixty days after the taking effect of the merger or
         consolidation, the dissenting stockholder may apply to the circuit
         court of the county wherein the principal place of business of the
         receiving corporation, in case of a merger, or the consolidated
         corporation, in case of a consolidation, is located, by petition for
         the appointment of appraisers to value his stock;

         (2) At any time during the above named sixty days any other dissenting
         stockholder or stockholders, in any corporation which is a party to the
         agreement, may file his or their petition in the court wherein the
         proceeding is pending for the determination of the value of their
         respective shares of stock affected by the merger or consolidation;

         (3) Any stockholder who does not become a party to such proceeding
         within the time herein prescribed shall be conclusively presumed to
         have assented to the merger or consolidation and shall be bound thereby
         as fully and as firmly as if he had voted therefor.

2. Within five days after the expiration of the period of sixty days, the court
wherein the proceeding is pending shall issue an order in which it shall fix the
time and place of the hearing under the petition or petitions then pending,
which shall not be more than twenty days after the issuance of the order. The
court shall cause to be served upon each party, or his attorney of record, at
last ten days before the hearing, a copy of the order fixing the time and place
of hearing. The hearing shall be before the court, and at the hearing the court
shall cause all petitions filed in the cause to be consolidated, and if the
court finds that each of the parties to the proceedings has been notified of the
time and place of hearing at least ten days before the hearing, then the court
shall appoint three disinterested householders of the county in which the
proceeding is pending, not related to either of the parties to the proceeding,
as appraisers to ascertain and determine the value of the shares of stock of the
dissenting stockholders, and upon the appointment, the court shall fix the time
and place of the first meeting of the appraisers; each of the appraisers shall
qualify by taking and subscribing an oath that he will faithfully and
impartially discharge the duties imposed upon him and will render a true
appraisement of the value of the stock of the dissenting stockholders in the
proceeding. Should any appraiser fail to qualify or serve, the court shall, by
an order duly entered, fill such vacancy.
