THE MERGER
 
  The Company, Sub and Tri-County have entered into the Agreement, a copy of
which is attached hereto as Annex A and incorporated herein by reference,
pursuant to which Tri-County will be merged with and into Sub, which will be
the surviving corporation. As more fully set forth below, the Agreement
provides, generally, that each of the shares of Tri-County Common Stock
outstanding immediately prior to the Effective Time (as defined in the
Agreement) of the Merger will be exchanged for seventeen (17) shares of the
Company common stock, par value $1.00 per share (the "Company Common Stock"),
and $140.00 in cash. See "The Merger--General;--Conversion of Tri-County Common
Stock."
 
  Fractional shares of the Company Common Stock will not be issued in
connection with the Merger. Holders of Tri-County Common Stock otherwise
entitled to a fractional share will be paid the value of the fractional share
in cash. See "The Merger--Fractional Shares."
 
STOCK CERTIFICATES; DIVIDEND WITHHOLDING
 
  Stockholders of Tri-County other than those Tri-County stockholders who
perfect their dissenters' rights of appraisal must surrender to the Company the
certificates for their shares of Tri-County Common Stock, and inform the
Company of their federal taxpayer identification number, before receiving any
cash or a certificate for the number of shares of the Company Common Stock to
which such stockholders are entitled. Until a Tri-County stockholder surrenders
the certificates for his Tri-County Common Stock and informs the Company of his
or her federal taxpayer identification number, the Company may withhold the
$140.00 per share cash portion of the consideration and the payment of any or
all dividends otherwise payable to such stockholder as a stockholder of the
Company. See "The Merger--Exchange of Stock Certificates."
 
CONDITIONS TO THE MERGER
 
  The Merger is subject to certain conditions, including approval of the
Agreement by the stockholders of Tri-County and by appropriate state and
federal banking authorities. Applications have been filed with appropriate
state and federal banking authorities seeking their approval of the Merger. See
"The Merger--Conditions to the Merger."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
  The Board of Directors of Tri-County believes that the Merger is in the best
interests of Tri-County and its stockholders and unanimously recommends that
stockholders vote FOR the approval of the Agreement. See "The Merger--Reasons
for the Merger."
 
DISSENTERS' RIGHTS OF APPRAISAL
 
  Holders of Tri-County Common Stock who are opposed to the Merger have the
right to dissent from the Merger in accordance with Section 17-6712 of the
Kansas General Corporation Code ("KGCC"), which provides that a stockholder
shall be entitled to receive the fair value of his shares as of the day prior
to the day on which the Merger is approved by the other Tri-County stockholders
if such stockholder: (1) delivers a written demand for appraisal of such shares
to Tri-County prior to the vote on the Agreement at the Tri-County Special
Meeting; (2) does not vote in favor of the Merger; and (3) makes written demand
for payment of the fair value of his shares within twenty (20) days after
receiving notice that the Merger became effective. See "The Merger--Rights of
Dissenting Stockholders."
 
ACCOUNTING TREATMENT
 
  The Merger will be treated by the Company as a purchase for accounting
purposes.
 
                                       5
<PAGE>
 
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The Merger is intended to qualify as a reorganization under Section 368(a)(1)
of the Internal Revenue Code of 1986, as amended (the "Code"). Payne & Jones,
Chartered will deliver as a condition of closing of the Merger an opinion,
based upon certain customary assumptions and representations, to the effect
that, for federal income tax purposes, no gain or loss will be recognized by
the Tri-County stockholders as a result of the Merger to the extent they
receive the Company Common Stock solely in exchange for their Tri-County Common
Stock. With respect to cash paid in accordance with the terms of the Agreement
and cash paid to the holders of Tri-County Common Stock as the result of the
exercise of dissenters' rights, normal recognition and gain and loss treatment
will apply. For a more complete description of the federal income tax
consequences, see "Federal Income Tax Consequences."
 
RISK FACTORS
 
  In determining whether to exchange Tri-County Common Stock for Company Common
Stock, the Tri-County stockholders should consider carefully the information
set forth under the caption "Risk Factors" and all information contained in
this Prospectus before making any decision to acquire Company Common Stock. See
"Risk Factors."
 
COMPARATIVE STOCK PRICES
 
  Shares of the Company Common Stock are listed on the NASDAQ National Market
("NASDAQ"). The last sale price of the Company Common Stock as reported on
NASDAQ on April 28, 1998 (the last trading day preceding the execution of the
Agreement, which was also the date preceding the announcement of the execution
of the Agreement), was $28.25 (or $14.12 adjusted for the 2 for 1 stock split
completed on May 18, 1998). The last sale price for the Company Common Stock as
reported by NASDAQ on           , 1998 (the most recent date for which it was
practicable to obtain market price data prior to the printing of this
Prospectus), was $         .
 
  As of           , 1998, there were forty-one holders of record of Tri-County
Common Stock. There is no established trading market for the shares of Tri-
County Common Stock and, other than approximately fourteen (14) sales made
pursuant to stockholders' agreements, management is aware of no other arm's
length sales of Tri-County Common Stock since formation of Tri-County in
          .
 
  Because the exchange ratio is fixed, a change in the market price of the
Company Common Stock before the Effective Time will affect the market value of
the Company Common Stock to be received in the Merger in exchange for the Tri-
County Common Stock. THERE CAN BE NO ASSURANCE AS TO THE MARKET PRICE OF THE
COMPANY COMMON STOCK AT ANY TIME BEFORE, AT OR AFTER THE EFFECTIVE TIME. TRI-
COUNTY STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR COMPANY
COMMON STOCK. THE COMPANY COMMON STOCK ISSUED IN CONNECTION WITH THE MERGER IS
EXPECTED TO BE LISTED ON NASDAQ.

                                 RISK FACTORS
 
KEY PERSONNEL
 
  Continued profitability of the Company after the Merger will be dependent on
the retention of a limited number of key persons, including Michael W.
Gullion, the Chairman, President and Chief Executive Officer of the Company,
and Keith E. Bouchey, the Executive Vice President, Secretary and Chief
Financial Officer of the Company. There will likely be a difficult transition
period if the Company lost the services of either or both men. In recognition
of this risk, the Company owns and is the beneficiary of an insurance policy
on the life of Mr. Gullion providing death benefits of $1.5 million and has
entered into employment agreements with Mr. Gullion and Mr. Bouchey. The
Company also places great value on the experience of presidents of the Company
Subsidiaries and the branches of the Company Subsidiaries and on their
relationships with the communities served by the Company Subsidiaries. The
loss of these key persons could negatively impact the affected banking
locations. There is no assurance the Company will be able to retain its
current key personnel or attract additional qualified key persons as needed.
 
CONTROL OF THE COMPANY BY MR. GULLION
 
  Following completion of the Merger, and assuming the issuance of 210,409
shares in the Merger, Michael Gullion will directly own 6.10% of the
outstanding stock of the Company, and through certain agreements will have the
right to vote an additional 10.65% of the Company Common Stock, for a total
voting power of 16.75% of the Company Common Stock. As a result, Mr. Gullion
will be in a position to control the management policy and conduct of the
business of the Company following the Merger.
 
ANTI-TAKEOVER MEASURES
 
  The Company has adopted certain provisions in its Amended and Restated
Articles of Incorporation and Restated Bylaws that may be considered as having
the effect of discouraging attempts to take over control of the Company. In
addition, the employment agreements of Mr. Gullion and Mr. Bouchey may require
the Company to make certain cash payments to them following a change in
control of the Company. Such provisions may benefit the Company's stockholders
if a takeover were attempted with a view to impose a merger, a sale of all or
substantially any part of the assets of the Company, or a similar transaction
that may not be in the best interests of all of the stockholders. On the other
hand, the anti-takeover provisions could adversely affect stockholders of the
Company by discouraging takeovers that are structured in a way that would be
favorable to the interests of the stockholders.
 
LIMITED TRADING HISTORY
 
  The Company's Common Stock has been listed on NASDAQ since November 1996.
Prior to that time there was no public market for the Company Common Stock.
There is no assurance that the Company Common Stock will experience in the
future the trading performance experienced since November 1996. Public markets
such as that on which the Company Common Stock is traded from time to time
experience price and volume volatility. These fluctuations may be unrelated to
the operating performance of particular companies whose shares are traded on
such markets. The market price could be subject to significant fluctuations in
response to the Company's operating results, the results of its competitors,
government regulations, litigation, and other factors.
 
YEAR 2000 RISKS
 
  Certain of the Company's older computer programs identify years with two
digits instead of four. This is likely to cause problems because the programs
may recognize the year 2000 as the year 1900. As with other financial
institutions, the Company engages in a significant amount of business and
reporting activity that depends on accurate date information, such as interest
and other calculations pertaining to loans, deposits, assets and investments.
As a result, Year 2000 problems could result in a system failure or
miscalculations that disrupt
 
                                       9
<PAGE>
 
operations. The Company is taking steps to implement permanent solutions
during 1998, rather than waiting until potential problems develop. A task
force began work on identifying and assessing potential issues in 1997, and
the Company is currently evaluating hardware and software solutions.
Appropriate resources are being allocated for hardware systems and software as
needed at each of the Company's Subsidiaries. The Company expects to be fully
Year 2000 compliant by late 1998, prior to any anticipated impact on operating
systems. Although the Company does not expect Year 2000 issues to have a
material adverse affect on its internal operations, it is possible that Year
2000 issues could have a material adverse affect on (i) the Company's
suppliers and their ability to service the Company, to accurately invoice for
services rendered and to accurately process payments received; and (ii) the
Company's customers in their ability to continue to utilize the Company's
services. The cumulative effect of such problems, if they occur, could have a
material adverse affect on the Company and the value of the Company Common
Stock and its other securities.
 
INTEGRATION OF ACQUIRED BANKS AND BUSINESSES; BUSINESS COMBINATIONS
 
  As part of its general strategy, the Company may, from time to time, acquire
community banks and other businesses that it believes provide a strategic fit
with its business. In fact, the Company currently has commitments or
agreements with respect to acquisitions other than Tri-County, and it has
reviewed potential acquisition candidates and has held preliminary discussions
with a number of these candidates. The acquisition of Tri-County and any other
banks or businesses will be accompanied by the risks commonly associated with
acquisitions. These risks include potential exposure to unknown liabilities of
acquired banks and businesses, the difficulty and expense of integrating the
operations and personnel of the banks or businesses, the potential disruption
to the business of the Company, the potential diversion of management time and
attention, the impairments of relationships with and the possible loss of key
employees and customers of the acquired banks or businesses, the incurrence of
amortization expenses if an acquisition is accounted for as a purchase and
dilution to the stockholders of the Company if the acquisition is made for
stock. The risks associated with the acquisition of Tri-County (as well as
other acquisitions) could have a material adverse affect on the Company and
the value of the Company Common Stock and its other securities. See "The
Companies--Pending Acquisitions."

LEGAL PROCEEDINGS
 
  Exchange Bank, along with approximately 24 other persons and entities
including a number of depository institutions, is a named defendant in a case
filed in the United States District Count for the District of Kansas on
September 11, 1997 on behalf of a putative class of over 2,400 persons who
allegedly invested at least $14,900 each in entities known as Parade of Toys
and Bandero Cigar Company. The complaint alleges violations of the Racketeer
Influenced Corrupt Organizations ("RICO") statute (18 U.S.C. 1962(c)),
conspiracy to violate RICO, negligent misrepresentation, fraud, civil
conspiracy and negligence on the part of the defendants. The plaintiffs
contend that the defendants, including Exchange Bank, were listed in trade
reference sheets provided to plaintiffs by Parade of Toys and Bandero Cigar
Company and that the defendants made false and misleading representations on
which they relied to their detriment. In each count, the plaintiffs have
sought actual damages in an amount in excess of $75,000 each, treble damages
under RICO, and punitive damages. Exchange Bank denies liability and is in the
process of vigorously defending this claim. A hearing was conducted on March
25, 1998, on the issue of class certification. On June 17, 1998, the
Magistrate issued a report and recommendation that the Court overrule the
plaintiff's motion for class certification. The parties now have ten days from
the date of such recommendation to file objections and the recommendation will
then be submitted to the trial judge for a determination of the motion.

                                  THE MERGER
 
GENERAL
 
  The Agreement and certain related matters are summarized below. This summary
does not purport to be a complete statement of the terms and conditions of the
Merger and is qualified in its entirety by, and made subject to, the more
complete information set forth in the Agreement attached as Annex A to this
Prospectus and incorporated herein by reference.
 
  At the Effective Time, Tri-County will merge with and into Sub, the separate
corporate existence of Tri-County will cease and Sub will survive and continue
to exist as a wholly-owned subsidiary of the Company. The Agreement has been
structured so that the aggregate value of the Company Common Stock to be
issued to Tri-County stockholders in the Merger will be uncertain.
Stockholders of Tri-County will receive seventeen (17) shares of Company
Common Stock and $140.00 cash for each share of Tri-County Common Stock. As a
result, Sub will pay to the stockholders of Tri-County a total of $1,732,780
in cash (excluding any amounts paid in cash to dissenting Tri-County
stockholders).
 
CONVERSION OF TRI-COUNTY COMMON STOCK
 
  At the Effective Time, automatically by virtue of the Merger and without any
action on the part of any party or stockholder, each share of Tri-County
Common Stock (excluding (i) shares held by Tri-County or by the Company or any
of the Company Subsidiaries, in each case other than in a fiduciary capacity
and (ii) any shares with respect to which dissenters' rights are being
exercised) issued and outstanding immediately prior to the Effective Time will
be converted into seventeen (17) shares of the Company Common Stock.
 
EXCHANGE OF STOCK CERTIFICATES
 
  At the Effective Time, certificates evidencing shares of Tri-County Common
Stock to be exchanged for shares of the Company Common Stock will be deemed
for all corporate purposes, other than the payment of
 
                                      13
<PAGE>
 
dividends and other distributions on such stock, to evidence ownership of such
shares of the Company Common Stock. As soon as practicable after the Effective
Time, the Company or its agent, as the exchange agent, will send a notice and
transmittal form to each record holder of certificates for Tri-County Common
Stock advising such holder of the procedures for surrendering Tri-County
certificates to the Company or its agent in exchange for a certificate for the
number of whole shares of the Company Common Stock and a check for the cash
amount to which such holder is entitled. The shares of the Company Common
Stock will be deemed to have been issued at the Effective Time. Promptly
following the surrender of the Tri-County certificates, the Company or its
agent will deliver to the surrendering Tri-County stockholders certificates
evidencing whole shares of the Company Common Stock and a check for the total
of $140.00 per share plus the cash amount of any fractional interest, (See "--
Fractional Shares") all in accordance with the notice and transmittal form.
Holders of Tri-County Common Stock will be entitled to dividends, without
interest, that may be declared and payable to holders of record of the Company
Common Stock after the Effective Time; provided, however, that any such
dividends will be remitted to each Tri-County stockholder entitled thereto,
without interest, at the time that such certificates representing shares of
Tri-County Common Stock are surrendered for exchange, subject to any
applicable abandoned property, escheat or similar law.
 
FRACTIONAL SHARES
 
  Neither certificates nor scrip representing fractional shares of the Company
Common Stock will be issued, but in lieu thereof, each holder of shares of
Tri-County Common Stock who would otherwise have been entitled to a fraction
of a share of the Company Common Stock will be paid the cash value of such
fraction determined by multiplying such fraction by the Average Company Price.
The Average Company Price means the average of the closing sale prices of the
Company Common Stock as reported by NASDAQ on each of the ten (10) consecutive
trading days preceding the third trading day prior to the Effective Time. The
Company will make available to the exchange agent, as required from time to
time, any cash necessary for this purpose.
 
BACKGROUND OF NEGOTIATIONS
 
  During the second half of 1997, Mr. Keith E. Bouchey, Executive Vice
President and Chief Financial Officer of the Company, initially contacted Mr.
James R. Pachta, Treasurer and Secretary of Tri-County, about a possible
business combination. On September 5, 1997, Mr. Bouchey made an oral
presentation to the Tri-County Board of Directors (the "Tri-County Board").
His presentation outlined the history of the Company and its present
strategies, including its strategy to grow through acquisitions and internal
expansion. In addition, he described the Company's goal of maintaining banks
with a local identity and board of directors and with management involved in
social and charitable activities of the communities served by the banks. The
Tri-County Board, after conferring with Terry White of GRA, Thompson, White &
Co. in Kansas City ("GRA") about value and timing issues, determined that no
action would be taken at that time.
 
  In January 1998, the Tri-County Board decided to explore possible sale
options and instructed management to begin discussions with potential
acquirers. Management, with the assistance of GRA, compiled a list of
potential acquirers, focusing on organizations that seemed compatible with the
communities where the Bank operates. Accordingly, management then entered into
discussions with three bank holding companies that operate in Kansas,
including the Company. As a result, the Company and two other bank holding
companies signed confidentiality agreements and began preliminary due
diligence in February 1998.
 
  The Company submitted its formal bid on March 10, 1998, and then revised its
offer, however, to include a combination of Company Common Stock and cash on
April 2, 1998. After completing its due diligence, the Company lowered the
terms of its offer to reflect concerns over asset quality as a result of a
recently completed regulatory examination. The Tri-County Board received one
other bid that it determined provided less value to Tri-County stockholders
than the Company's bid. The third bank holding company failed to submit a bid.
 
  On April 20, 1998 the parties reached an agreement in principle and
immediately began drafting the Agreement. The Tri-County Board negotiated to
ensure that Tri-County stockholders would receive freely-
 
                                      14
<PAGE>
 
transferable registered Company Common Stock in a tax-free transaction. After
satisfying themselves that the business plan of the Company was consistent
with all of their objectives for Tri-County and its stockholders, the Tri-
County Board authorized the execution of the Agreement.
 
REASONS FOR THE MERGER
 
  Tri-County. The Tri-County Board believes that the terms of the Agreement
are fair to, and in the best interests of, Tri-County and its stockholders. In
considering the terms and conditions of the Agreement, the Tri-County Board
considered a number of factors. They did not assign any relative or specific
weights to the factors considered. The material factors considered were:
 
    The Financial Terms and Structure of the Merger. The Tri-County Board is
  of the view that, based on historical and anticipated trading ranges for
  the Company Common Stock, the value of the consideration to be received by
  Tri-County stockholders represents a fair multiple of Tri-County's per
  share book value and earnings. Additionally, the Board recognized that the
  shares of the Company Common Stock are listed for trading on NASDAQ and
  provide a liquid investment as compared to shares of Tri-County Common
  Stock. The Tri-County Board also considered that, except for the cash to be
  received by Tri-County stockholders, the Merger would qualify as a tax-free
  reorganization under the Internal Revenue Code of 1986, as amended (the
  "Code"). See "Federal Income Tax Consequences."
 
    The Non-Financial Terms of the Merger. The Tri-County Board considered
  the social and economic effect on the employees, depositors and customers
  of, and others dealing with, the Bank and on the community in which the
  Bank operates. They concluded that because of its large menu of banking and
  banking related products, strong management, transaction experience and
  history of operating acquired banking locations as community banks, the
  Company would be an excellent successor to the existing Bank owners.
 
  The Company. In approving the Agreement, management of the Company
considered the price, financial condition of the Bank, projected synergies the
Company anticipates will result from the Merger and the compatibility of the
businesses of the two banking organizations. The management of the Company
concluded that the Merger is consistent with its strategy to acquire community
banks with strong existing management located in county seat towns.
 
  THE TRI-COUNTY BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT TRI-COUNTY
STOCKHOLDERS VOTE "FOR" APPROVAL OF THE AGREEMENT.
 
OPERATIONS AND MANAGEMENT AFTER THE MERGER
 
  At the Effective Time, the separate corporate existence of Tri-County will
terminate and all of the assets and liabilities of Tri-County will become
assets and liabilities of Sub. The Articles of Incorporation and Bylaws of Sub
as in effect immediately prior to the Effective Time shall be and remain the
Articles of Incorporation and Bylaws of the surviving corporation from and
after the Effective Time until amended as provided by law. The officers and
directors of Sub will become the officers and directors of the surviving
corporation from and after the Effective Time. The Bank will receive
assistance in bringing new methods and systems to the Bank. The Company also
expects to enhance the net interest margin and non-interest income of the Bank
by expanding the products and services offered.
 
  The Company will analyze the Bank's operations for potential efficiencies.
The Company anticipates achieving operating cost savings through the proposed
consolidation and the elimination of redundant costs. While there can be no
assurances that operating cost savings will be realized or in what fiscal
period the savings will actually be recorded, plans are currently being
developed to realize operating cost savings. It is expected that the
annualized level of operating cost savings achieved will be realized unevenly
throughout the period of consolidation, with the majority of any savings
realized in the latter part of the period. The extent to which
 
                                      15
<PAGE>
 
operating cost savings will be achieved depends, among other things, on the
regulatory environment and economic conditions, and may be affected by
unanticipated changes in business activities, inflation and operating costs.
 
CONDITIONS TO THE MERGER
 
  Consummation of the Merger is subject to the fulfillment of certain
conditions set forth in the Agreement, including the following:
 
    (a) Approval of the Agreement by the holders of a majority of all the
  outstanding shares of Tri-County Common Stock;
 
    (b) The accuracy of representations of the Company and Tri-County made in
  the Agreement and the performance of their respective obligations
  thereunder;
 
    (c) The absence of a material adverse event since April 29, 1998,
  effecting the financial condition, properties, assets, liabilities, rights,
  business or prospects of the Company, Tri-County or the Bank;
 
    (d) The absence on the closing date, except as previously disclosed, of
  (1) any actions, suits, claims, demands or other proceedings or
  investigations threatened against or affecting the properties, assets,
  rights or business of Tri-County or the Bank or the right to carry on their
  respective businesses; (2) any debt, liability or obligation of Tri-County
  or the Bank not reflected in their financial statements or not occurred in
  the ordinary course of business; and (3) any material breach or default of
  Tri-County or the Bank under any agreement or commitment.
 
    (e) The receipt by the Company, Tri-County and the Bank of an opinion

    (g) The receipt of necessary regulatory approvals;

  Bank; and
 
    (i) The absence of any pending or threatened litigation that could
  reasonably result in restraining, enjoining or prohibiting consummation of
  the Merger.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
  Pursuant to the Agreement, Tri-County has agreed to carry on its business in
the usual, regular and ordinary course in substantially the same manner as
conducted prior to the execution of the Agreement.
 
NO SOLICITATION
 
  The Agreement provides that, unless and until the Merger has been
terminated, neither Tri-County nor the Bank will solicit or encourage or,
subject to the fiduciary duties of their directors as advised by counsel, hold
discussions or negotiations with, or provide information to, any person in
connection with any proposal from any person relating to the transaction of
all or a substantial portion of the business, assets or stock of Tri-County or
the Bank. Tri-County is required to promptly advise the Company of the receipt
of, and the substance of, any such proposal or inquiry.
 
WAIVER AND AMENDMENT
 
  Prior to or at the Effective Time, any provision of the Agreement,
including, without limitation, the conditions to consummation of the Merger,
may be (i) waived, to the extent permitted under law, in writing by the party
which is entitled to the benefits thereof; or (ii) amended at any time by
written agreement of the parties, whether before or after approval of the
Agreement by the stockholders of Tri-County; provided, however, that
 
                                      16
<PAGE>
 
after any such approval, no such amendment or modification shall alter the
amount or change the form of the consideration or alter or change any of the
terms of the Agreement if such alteration or change would adversely affect the
holders of Tri-County Common Stock. It is anticipated that a condition to
consummate the Merger would be waived only in those circumstances where the
Board of Directors of the Company, Sub, or Tri-County, as the case may be,
deems such waiver to be in the best interests of such company and its
stockholders.
 
TERMINATION OF THE MERGER
 
  The Agreements and the Merger may be terminated at any time prior to the
closing date by:
 
    (i) The mutual consents of the Boards of Directors of the Company, Sub
  and Tri-County;
 
    (ii) The Company, if any regulatory approval shall be denied or if any
  such regulatory approval shall be conditioned or restricted in any manner
  which would materially adversely affect the operations of or would be
  unduly burdensome to the Company;
 
    (iii) Tri-County or the Company if the other party has materially
  breached the Agreement and has not cured such breach;
 
    (iv) Tri-County or the Company upon written notice to the other of any
  other condition imposed for the benefit of such party that shall not have
  been satisfied or waived prior to the closing date; or
 
    (v) Tri-County or the Company if the Merger has not been consummated by
  December 31, 1998.
 
EFFECTIVE TIME
 
  It is presently anticipated that the Effective Time of the Merger will occur
sometime in the third quarter of 1998, but no assurance can be given to that
effect.
 
FEDERAL SECURITIES LAWS CONSEQUENCES
 
  The shares of the Company to be issued pursuant to the Merger have been
registered under the Securities Act of 1933, as amended (the "Securities
Act"). The provisions of Rule 145 under the Securities Act allow such shares
to be sold without restriction by stockholders of Tri-County who are not
deemed to be "affiliates" (as that term is defined in the rules under the
Securities Act) of Tri-County and who do not become affiliates of the Company.
The shares of the Company to be issued to affiliates of Tri-County may be
resold only pursuant to an effective registration statement, pursuant to Rule
145 under the Securities Act, or in transactions otherwise exempt from
registration under the Securities Act. The Company will not be obligated and
does not intend to register its shares under the Securities Act for resale by
stockholders who are affiliates.
 
FEES AND EXPENSES OF THE MERGER
 
  Except as set forth as follows, each party is responsible for its own
expenses in connection with the Merger. However, if the Merger does not close
for any reason, Tri-County will pay $30,000.00 of the total cost associated
with (i) the certified audit of the financial statements of Tri-County and
(ii) the preparation and filing of the Registration Statement and Prospectus.
If the Merger closes, then such $30,000.00 payment will be made by the
stockholders of Tri-County (on a pro rata basis).
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
  In order to have dissenters' rights, a holder of Tri-County Common Stock
must not vote his or her shares in favor of the Agreement or deliver an
unmarked, but signed proxy. If the Merger is approved, holders of shares of
Tri-County Common Stock will possess the right to seek appraisal of their
shares pursuant to Section 17-6712 of the KGCC ("Section 17-6712").
 
                                      17
<PAGE>
 
  THE FOLLOWING IS A SUMMARY OF THE PROVISIONS OF SECTION 17-6712 AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH SECTION, A
COPY OF WHICH IS ATTACHED TO THIS PROSPECTUS AS ANNEX B. THE FAILURE TO COMPLY
WITH THE PROVISIONS OF SECTION 17-6712 MAY RESULT IN A TERMINATION OR LOSS OF
APPRAISAL RIGHTS THEREUNDER.
 
  A holder of record of shares of Tri-County Common Stock who elects to
exercise appraisal rights under Section 17-6712 must deliver a written
objection to the Agreement to Tri-County prior to the vote on the Agreement by
the holders of Tri-County Common Stock at the Tri-County Special Meeting to be
held on            , 1998. Any such objection should be sent to Tri-County at
the Linn City Building, 104 5th Street, Linn, Kansas 66953, Attention: Don R.
Moser.
 
  Within 10 days after the Effective Date, Sub, as the surviving corporation
in the Merger, will give written notice to each former holder of shares of
Tri-County Common Stock who has complied with the written notice requirement
that the Merger has become effective and that dissenters' rights are available
for any or all of such holder's shares in connection therewith. Within 20 days
after the date of the mailing of the notice, such holder must demand in
writing to Sub the payment of the fair value of such holder's shares of Tri-
County Common Stock. Any such demand should be sent to Sub at 11301 Nall
Avenue, Leawood, Kansas 66211, Attention: Keith E. Bouchey. Within 30 days
after the expiration of the 20 day period, Sub shall pay to such holder the
value of such holder's shares, exclusive of any element of value arising from
the expectation or accomplishment of the Merger.
 
  If Sub and a dissenting stockholder fail to agree upon the fair value of the
Tri-County Common Stock, within four months after the Effective Time of the
Merger, but not thereafter, either Sub or any stockholder entitled to
dissenters' rights under Section 17-6712 may file a petition in the District
Court of Kansas demanding a determination of the value of the stock of all
stockholders entitled to appraisal. Inasmuch as Sub has no obligation to file
such a petition, the failure of a stockholder to do so within the period
specified could nullify such stockholder's previous written demand for
appraisal.
 
  If a petition for appraisal described above is timely filed by a
stockholder, Sub is obligated to provide the stockholder with a verified list
of all stockholders who have demanded appraisal. After notice to such
stockholders, the court is empowered to conduct a hearing upon the petition,
to determine those stockholders entitled to appraisal and to determine the
"fair value" of the shares held by them as of the date on which the Merger is
consummated, which under the KGCC would be determined exclusive of any element
of value arising from accomplishment or expectation of the Merger.
 
  When the "fair value" is so determined, the court will direct the payment by
Sub of such value, with interest thereon if the court so determines, to the
stockholders entitled to receive the same, upon surrender to Sub by such
stockholders of the certificates representing their shares of Tri-County
Common Stock to Sub at the address specified above. Upon application of Sub or
any stockholder entitled to participate in the appraisal proceeding, the court
may in its discretion permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of those
other stockholders entitled to an appraisal who have complied with the above
conditions.
 
TRANSACTIONS BETWEEN THE COMPANY AND TRI-COUNTY
 
  No shares of Tri-County Common Stock are presently owned by the Company or
by any of its subsidiaries or principals, or by trustees for the benefit of
the Company or any of its subsidiaries, stockholders or employees as a class
or by an escrow arrangement instituted by the Company.
 
ACCOUNTING TREATMENT
 
  It is intended that the Merger will qualify as a purchase for financial
reporting purposes.

                        FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion is based upon the provisions of the Code, the
applicable regulations thereunder, judicial authority, current administrative
rulings and practice as of the date hereof and the opinion to be provided by
Payne & Jones, Chartered. The opinion of Payne & Jones, Chartered will be
based upon certain assumptions and representations by the management of each
of Tri-County and the Company and by certain holders of the outstanding Tri-
County Common Stock. A ruling from the Internal Revenue Service concerning the
tax consequences of the Merger will not be requested. The following discussion
does not address the federal income tax consequences to special classes of
taxpayers including, without limitation, foreign corporations, tax exempt
entities and persons who acquired their Tri-County Common Stock pursuant to
the exercise of an employee option or otherwise as compensation.
 
  In the opinion of Payne & Jones, Chartered, the Merger will constitute a
reorganization within the meaning of Section 368(a)(1)(A) (as amplified by
Section 368(a)(2)(D)) of the Code. Consequently:
 
    1. Stockholders of Tri-County will not recognize gain or loss upon the
  receipt of the Company Common Stock in exchange for their shares of Tri-
  County Common Stock.
 
    2. The basis of the Company Common Stock received by stockholders of Tri-
  County in the Merger will equal the basis of their stock exchanged.
 
    3. The tax holding period of the Company Common Stock received by
  stockholders of Tri-County in the Merger will include the holding period of
  their stock exchanged.
 
    4. Cash paid under the terms of the Agreement, to holders of shares of
  Tri-County who dissent from the Merger and to holders of shares of Tri-
  County in lieu of fractional shares will be treated as proceeds of sales on
  which gain or loss will be recognized.
 
  THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY. EACH TRI-COUNTY STOCKHOLDER SHOULD CONSULT HIS OR HER OWN
TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO HIM OR HER,
INCLUDING THE APPLICATION AND EFFECT OF FEDERAL, STATE AND LOCAL AND OTHER TAX
LAWS.

                      COMPARATIVE RIGHTS OF STOCKHOLDERS
 
GENERAL
 
  Tri-County is incorporated in the State of Kansas. Tri-County stockholders,
whose rights are currently governed by Kansas law (including the KGCC), the
Tri-County Articles of Incorporation (the "Tri-County Articles") and the Tri-
County bylaws (the "Tri-County Bylaws"), will, upon consummation of the
Merger, become stockholders of the Company. After such time, their rights will
continue to be governed by Kansas law; however, they will be subject to the
provisions of the Company Amended and Restated Articles of Incorporation (the
"Company Articles") and the Company Amended and Restated Bylaws (the "Company
Bylaws").
 
  Material differences that may affect the rights and interests of
stockholders of Tri-County are set forth below. This summary is not intended
to be an exhaustive description of the provisions discussed. It is qualified
in its entirety by reference to the Tri-County Articles, the Tri-County
Bylaws, the Company Articles and the Company Bylaws.
 
NUMBER OF DIRECTORS AND TERM
 
  Under the Tri-County Bylaws, the Tri-County Board consists of eleven
directors, each of whom serve a term of one year. Under the Company Articles
and the Company Bylaws, the Company Board consists of at least three, but not
more than fifteen directors. Currently, the Company Board consists of five
directors. The Company Bylaws provide that directors are elected to a three
year term. The Company Articles and the Company Bylaws provide for a staggered
Board of Directors comprised of three classes as nearly equal in size as
practicable. Each class holds office until the third annual meeting for
election of directors following the election of such class.
 
ELECTION OF DIRECTORS
 
  The Tri-County Bylaws provide for the use of cumulative voting by Tri-County
stockholders in any election of directors. Under the Company Articles,
stockholders of the Company are not entitled to use cumulative voting on any
matter.
 
REMOVAL OF DIRECTORS
 
  Under the Tri-County Bylaws, directors may be removed by the stockholders
for good cause; provided, however, no director may be removed if the votes
cast against removal would be sufficient to elect the director if then
cumulatively voted at a regular election of the entire Tri-County Board. The
Company Articles provide that any director or the entire board of directors
may only be removed for "cause," as defined in the Company Articles.
 
SPECIAL MEETINGS
 
  The Tri-County Bylaws provide that the President, the Tri-County Board, or
one or more stockholders holding not less than one-fifth of the voting power
may call a special meeting of the Tri-County stockholders. The Company Bylaws
provide that special meetings of the Company stockholders may only be called
by the chief executive officer, the Company Board, or the written request of
the holders of fifty-five percent of the outstanding shares.
 
AMENDMENT OF ARTICLES OF INCORPORATION
 
  Under the KGCC, the Tri-County Articles may be amended upon a resolution of
the Tri-County Board proposing the amendment and its submission to the Tri-
County stockholders for their approval by the majority of the shares of Tri-
County Common Stock entitled to vote.
 
                                      22
<PAGE>
 
  The Company Articles provide that certain provisions of the Company Articles
may not be repealed or amended without the affirmative vote of holders of at
least two-thirds of the outstanding shares of voting stock. Company
stockholders holding a majority of the Company Common Stock may otherwise
amend, alter, change or repeal any provision of the Company Articles.
 
ACTION BY STOCKHOLDERS
 
  The Tri-County Bylaws permit any action that may be taken at a meeting of
the stockholders, except for certain fundamental matters outlined in the Tri-
County Bylaws, to be taken without a meeting if authorized in writing by all
stockholders entitled to vote upon such action at the meeting.
 
  The Company Articles provide that any action required or permitted to be
taken by the stockholders of the Company must be effected at a duly called
annual or special meeting and may not be effected by any consent in writing by
such stockholders.
 
AMENDMENT OF BYLAWS
 
  The Tri-County Bylaws provide that the stockholders may make, alter, amend
or repeal their bylaws by a majority vote. The Company Articles authorize the
Company Board to make, alter and repeal bylaws, subject to the rights of
stockholders at any regular or special meeting to alter or repeal bylaws made
by the Company Board. Stockholders of the Company may make, alter, amend or
repeal the Company Bylaws by a majority vote, except that the amendment of
certain provisions requires a two-thirds vote.
 
NOTICE OF STOCKHOLDER PROPOSALS; NOMINATIONS OF DIRECTORS
 
  The Tri-County Bylaws do not contain special requirements for providing
advance notice of the introduction by stockholders of business to be
transacted at stockholder meetings.
 
  The Company Bylaws provide that any stockholder who intends to bring a
matter before the annual meeting of stockholders must deliver written notice
of such stockholder's intent to the Secretary of the Company. Such notice must
be received by the Secretary not later than 120 days prior to the day
corresponding to the date on which the Company released its proxy statement in
connection with the previous years annual meeting. Such written notice must
set forth (i) a brief description of the proposal and the reasons for it, (ii)
the name and address of the stockholder, (iii) the class and number of shares
of capital stock of the Company beneficially owned by the stockholder, (iv)
any arrangement between such stockholder and any other person in connection
with the proposal and any material interest of the stockholder in the proposed
business described in the notice, (v) a representation that such stockholder
will appear in person or proxy at the annual meeting and (vi) if such business
is a nomination for director, each nomination sought to be made, together with
a description of the qualifications and business or professional experience of
each proposed nominee and disclosing the information about him or her that is
required by the Securities Exchange Act of 1934 and the rules and regulations
promulgated thereunder, to be disclosed in the proxy materials for the meeting
involved as if he or she were a nominee of the corporation for election as one
of its directors.
 
             PRO FORMA UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
 
  The following unaudited pro forma financial information combines the
historical consolidated balance sheets and statements of income of the Company
and Tri-County, including their respective subsidiaries, after giving effect
to the Merger. The unaudited pro forma consolidated balance sheet at March 31,
1998 gives effect to the Merger as if it had occurred at March 31, 1998. The
unaudited pro forma consolidated statements of income for the year ended
December 31, 1997 and the three-month period ended March 31, 1998, give effect
to the Merger as if it had occurred at January 1, 1997. These statements are
prepared on the basis of accounting for the Merger as a purchase transaction
and are based on assumptions set forth in the notes thereto.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF TRI-COUNTY
 
  The following discussion of financial condition and results of operations
should be read in conjunction with the consolidated financial statements of
Tri-County and the Bank (together, "Tri-County") and the notes thereto, which
are included elsewhere in this prospectus.
 
COMPARISON OF OPERATING RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 1998 AND
1997
 
 General
 
  Tri-County's consolidated net earnings totaled $74,000 for the three months
ended March 31, 1998 compared to a $58,000 net loss for the same period in
1997. Earnings before income taxes were $131,000 for the first three months of
1998 compared to losses totaling $99,000 for the same period in 1997. The
primary reason for higher earnings before tax and net earnings is a decrease
in provision for loan losses of $233,000.
 
 Net Interest Margin
 
  Total interest income was $844,000 for each of the three month periods ended
March 31, 1998 and 1997. Interest income on loans decreased $20,000, or 3.1%,
primarily due to a $1.1 million decrease in the average balance of loans
outstanding during the period ended March 31, 1998 compared to the same period
ended March 31, 1997. Interest earned on federal funds sold and interest-
bearing deposits in other financial institutions increased $18,000, or 69.9%,
for the first three months of 1998 compared to the same period in 1997. This
increase is attributable to higher average balances outstanding in the first
three months of 1998 compared to the same period in the previous year.
 
  Total interest expense increased $7,000, or 1.4%, for the three months ended
March 31, 1998 compared to the same period in 1997. An increase in interest
expense of $3,000 on savings deposits and interest-bearing checking accounts
from the first three months of 1997 to the same period in 1998 was a result of
an increase of $373,000, or 2.9%, in the average balance of these accounts
between the two periods. The average balance of time deposits and long-term
borrowings also increased slightly from the first three months of 1997
compared to the same period in 1998 contributing to the remaining increase in
interest expense.
 
  As a result of the changes described above, the net interest margin
decreased $7,000, or 1.7%, for the three months ended March 31, 1998 compared
to the three months ended March 31, 1997.
 
 Provision for Loan Losses
 
  The provision for loan losses was $16,000 for the first three months of 1998
compared to $249,000 for the same period in 1997. Tri-County experienced
significant commercial and non-residential real estate loan charge-offs in the
first three months of 1997, and as a result, additional provisions for loan
losses were recorded during the period. Tri-County has not experienced the
same level of charge-offs in the first three months of 1998 and
correspondingly has recorded lower provisions during that period.
 
 Other Income
 
  Other income decreased by $16,000, or 17.5%, for the three months ended
March 31, 1998 compared to the same period in 1997. The decrease in other
income was primarily a result of a decrease in service charges earned on
deposit accounts.
 
 Other Expense
 
  Other expense decreased by $20,000, or 6.0%, for the first three months of
1998 compared to the same period in 1997. The decrease in other expense was
primarily due to a decrease in salaries and benefits of $26,000.
 
                                      27

 Income Tax Expense
 
  Tri-County recognized income tax expense of $57,000 in the first three
months of 1998 compared to an income tax benefit of $41,000 for the same
period in 1997. The effective tax rates were 43.5% and 41.0% for the three
month periods ended March 31, 1998 and 1997, respectively.
 
COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996
 
 General
 
  Tri-County's consolidated net loss for the year ended December 31, 1997
totaled $22,000 compared to net earnings for the year ended December 31, 1996
of $256,000 representing a decrease of $278,000. The decrease in net earnings
is attributable to an increase of $476,000 in the provision for loan losses
partially offset by a $50,000 decrease in other expenses and a $177,000
decrease in income tax expense.
 
 Net Interest Margin
 
  Total interest income increased by $87,000, or 2.6%, in 1997 compared to
1996. Interest income on loans increased $74,000, or 2.9%, due primarily to an
increase of $2.3 million in the average balance of loans outstanding in 1998
compared to 1997. This increase was partially offset by an overall decrease in
the yield earned on loans.
 
  Total interest expense increased by $118,000, or 6.9%, in 1997 compared to
1996. An increase of $110,000, or 8.1%, in interest expense on time deposits
contributed significantly to the overall increase. The increase in the average
balance of time deposits in 1997 was $1.7 million, or 7.3%, compared to 1996.
 
  The net interest margin decreased $31,000, or 1.8%, compared to 1996 as a
result of the changes described above.

 Provision for Loan Losses
 
  During 1997, Tri-County recorded provisions for loan losses of $759,000
compared to $283,000 in 1996. The increase in provision for loan losses was
directly attributable to higher charge-offs of commercial and real estate
mortgage loans. Net charge-offs were $617,000 in 1997 compared to $111,000 in
1996. The increase in charged-off loans in 1997 compared to 1996 is related to
an identified group of loans, which were originated by
 
                                      30
<PAGE>
 
a previously employed member of management. Such loans did not meet Tri-
County's established underwriting guidelines. Management has identified these
loans and either appropriately charged-off or reserved for any potential
losses related to these loans. The allowance for loan losses totaled $642,000,
or 2.3%, of gross loans at December 31, 1997.
 
 Other Income
 
  Other income remained stable, increasing slightly from $337,000 in 1996 to
$339,000 in 1997. Tri-County's service charges on deposit accounts increased
$14,000, or 5.6%, in 1997 compared to 1996. This increase was offset by a
decrease in other miscellaneous income in 1997 compared to 1996.
 
 Other Expense
 
  Other expense decreased $50,000, or 3.8%, in 1997 compared to 1996. The
decrease in other expense is primarily attributable to a decrease of $19,000,
or 10.8%, in furniture and equipment expense related to lower software
maintenance and depreciation expense in 1997 compared to 1996. Also
contributing to the decrease in other expense was an $18,000 decrease in other
operating expenses related primarily to lower printing and stationery supplies
in 1997 compared to 1996.
 
 Income Tax Expense
 
  Tri-County recognized an income tax benefit of $47,000 in 1997 versus income
tax expense of $130,000 in 1996. The income tax benefit recognized in 1997 was
due to significant recording of provision for loan losses which created a net
loss before taxes.

  Net loans decreased from $28.6 million a December 31, 1996 to $27.4 million
at December 31, 1997. This decrease in loan balances is a result of Tri-County
implementing more stringent underwriting guidelines in 1997. Total deposits
remained relatively stable increasing from $39.8 million at December 31, 1996
to $40.0 million at December 31, 1997. The resulting loan to deposit ratios of
71.9% and 68.5% as of December 31, 1996 and December 31, 1997 decreased as a
result of the implementation of the more stringent underwriting guidelines.
 
 Liquidity and Capital Resources
 
  Liquidity risk is managed by Tri-County through the composition of its
assets and liabilities in an effort to efficiently meet 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 Tri-County's liquidity are cash and cash
equivalents and investment securities with short-term maturities. Tri-County
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.
 
  As of December 31, 1997, Tri-County had cash and cash equivalents of
approximately $1.6 million, interest bearing deposits of $2.1 million and
investment securities maturing in less than one year of $4.3 million. These
amounts represent approximately 25.7% of Tri-County's total assets at December
31, 1997 and provide Tri-County with sufficient resources to handle unforeseen
deposit outflows and loan requirements.
 
                                      31
<PAGE>
 
  Tri-County's cash and cash equivalents increased approximately $84,000 for
the year ended December 31, 1997. Net cash provided by operating activities
aggregated $491,000. Net cash used in investing activities for the year was
$754,000, primarily as the result of $2.2 million of interest bearing deposits
in other financial institutions, net of maturities of approximately $1.1
million partially offset by an increase in net loans of $427,000. Net cash
provided by financing activities approximated $347,000 for the year as a
result of a net increase in federal funds purchased of $200,000 and an
increase in net deposit balances of $168,000, partially offset by $95,000 in
purchases of treasury stock.
 
  Stockholders' equity represented 6.7% of total assets at December 31, 1997.
Risk-based capital and leverage ratios of the subsidiary bank at December 31,
1997 exceeded levels considered necessary to be classified as an "adequately
capitalized" institution by regulatory banking authorities.
 
 Effects of Economic Conditions
 
  Tri-County's consolidated 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 primary impact of inflation on the operations of Tri-County is reflected
in increased operating costs. Unlike most industrial companies, virtually all
of the assets and liabilities of a financial institution are monetary in
nature. As a result, changes in interest rates have a more significant impact
on the performance of a financial institution than do changes in prices.
Interest rate changes do not necessarily move in the same direction or have
the same magnitude as changes in the prices of goods and services.
 
  The local economies of Washington and Cloud counties are heavily dependent
on agriculture and related business.

 Agricultural and Commercial
 
  Agricultural and commercial loans are comprised mainly of loans to customers
in the Washington and Cloud County trade areas and are dependent, to a large
extent, on the agricultural sector. Consistent with management's emphasis on
relationship banking, most borrowing customers also maintain deposit accounts
and utilize other banking services.
 
 Real Estate--Mortgage
 
  This category of the loan portfolio consists of residential and farmland
loans for properties located in Washington County, Kansas and Cloud County,
Kansas. These loans aggregated approximately $8.9 million and $9.9 million at
December 31, 1997 and 1996, respectively.
 
                                      32
<PAGE>
 
 Consumer
 
  The consumer loan portfolio consists of both secured and unsecured loans to
individuals for various personal reasons such as automobile financing, home
improvements, educational and recreational purposes.
 
ALLOWANCE FOR LOAN LOSSES
 
  Provisions for losses on loans receivable are based upon management's
estimate of the amount required to maintain an adequate allowance for losses,
relative to the risk in the loan portfolio. This estimate is based on reviews
of the loan portfolio, including assessment of the estimated net realizable
value of the related underlying collateral, and upon consideration of past
loss experience, current economic conditions and such other factors that, in
the opinion of management, deserve current recognition. Amounts are charged
off as soon as probability of loss is established, taking into consideration
such factors as the borrower's financial condition, underlying collateral and
guarantees. Loans are also subject to periodic examination by regulatory
agencies. Such agencies may require charge-offs or additions to the allowance
based upon their judgments about information available at the time of their
examination. The following table presents the allowance for loan losses at the
dates indicated (dollars in thousands):

</TABLE>
 
  If non-accrual loans had been current in accordance with their original
terms and had been outstanding throughout 1997, Tri-County would have
recognized an additional $113,000 of interest income on these loans. No
interest income was included in net income from these loans in 1997.
 
  Management reviews Tri-County's loan portfolio on a continuous 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 under close supervision, with
consideration given to placing the loan on a non-accrual status. Management
then determines the need for additions to the allowance for loan loss, or, if
appropriate, partial or full charge-off of the loan. Depending upon the
circumstances, certain of these loans are from time to time renegotiated.
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 placed on nonaccrual status. After a loan is placed
on nonaccrual status, any interest previously accrued but not yet collected is
reversed against current income. Interest is included in income subsequent to
the date the loan is placed on nonaccrual status on a cash basis so long as
management is satisfied there is no 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.

  As of December 31, 1997, loans repricing after one year include
approximately $4.1 million in fixed rate loans and $15.2 million in floating
or adjustable rate loans.
 
 Interest Rate Risk
 
  Asset and liability management encompasses both interest rate risk and
liquidity management. Tri-County'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. Tri-County monitors its assets and
liability mix in an effort to maintain a consistent earnings performance
through control of interest rate risk.

  Below is a "static gap" schedule for Tri-County as of December 31, 1997 (in
thousands). 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 schedule. 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 schedule indicates Tri-County is liability sensitive in the 0-3 month
period and is asset sensitive for all other periods. This means, that during
the 0-3 month period, interest bearing liabilities would be 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 Tri-County's sensitivity position.

ACCOUNTING AND FINANCIAL REPORTING
 
  The Financial and Accounting Standards Board (FASB) issued SFAS No. 130,
Reporting Comprehensive Income in June 1997. SFAS No. 130 requires classifying
items of other comprehensive income by their nature in the financial
statements and displaying the accumulated balance of other comprehensive
income separately from retained earnings and additional paid-in capital in the
equity section of the statement of stockholders' equity. SFAS No. 130 is
effective for fiscal years beginning after December 31, 1997. The adoption of
the standard is not expected to have a significant impact on the financial
statements of Tri-County.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Tri-County Bancshares and Subsidiary:
 
  We have audited the accompanying consolidated balance sheet of Tri-County
Bancshares and subsidiary as of December 31, 1997 and the related consolidated
statement of earnings, stockholders' equity and cash flows for the year then
ended. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall consolidated financial statement presentation.
We believe that our audit provides 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 Tri-County
Bancshares and subsidiary as of December 31, 1997 and the results of their
operations and their cash flows for the year then ended, in conformity with
generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1997 AND 1996
   (INFORMATION AS OF AND FOR THE YEAR ENDED DECEMBER 31, 1996 IS UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 (a) Principles of Consolidation
 
  The consolidated financial statements include the accounts of Tri-County
Bancshares, Inc. and its subsidiary, Tri-County Bank (the Bank), collectively
referred to as the Company. All significant intercompany transactions have
been eliminated.
 
 (b) Investment Securities
 
  The Company classifies investment securities as either available-for-sale or
held-to-maturity. Held-to-maturity securities are those which the Company has
the positive intent and ability to hold to maturity. All other securities are
classified as available-for-sale.
 
  Held-to-maturity securities are recorded at amortized cost. Available-for-
sale securities are recorded at fair value. Unrealized holding gains and
losses, net of related tax effect, on available-for-sale securities are
excluded from earnings and reported as a separate component of stockholders'
equity until realized.
 
  A decline in the fair value of any security below cost that is deemed other
than temporary is charged to income resulting in the establishment of a new
cost basis for the security.
 
  Premiums and discounts are amortized or accreted over the life of the
related security as an adjustment to interest income. Interest income is
recognized when earned. Realized gains and losses are included in income using
the specific identification method for determining the basis of the securities
sold.
 
 (c) Land, Buildings and Equipment
 
  Land, buildings and equipment are stated at cost less accumulated
depreciation. Depreciation is computed over the estimated useful life of the
respective assets, ranging from three to thirty-nine years, utilizing
primarily the straight-line method.
 
  Costs of maintenance and repairs are charged to expense as incurred. Major
betterments are considered individually and are expensed or capitalized as the
facts dictate.
 
 (d) Recognition of Income on Loans
 
  Interest income on loans is accrued based on the principal amount
outstanding. The accrual of interest on impaired loans is discontinued when,
in management's opinion, the interest will not be collectible in the ordinary
course of business. When interest accrual is discontinued, all unpaid accrued
interest is reversed.
 
 (e) Provision for Loan Losses
 
  Provisions for losses on loans receivable are based upon management's
estimate of the amount required to maintain an adequate allowance for losses,
relative to the risk in the loan portfolio. This estimate is based on reviews
of the loan portfolio, including assessment of the estimated net realizable
value of the related underlying collateral, and upon consideration of past
loss experience, current economic conditions and such other factors which, in
the opinion of management, deserve current recognition. Amounts are charged
off as soon as probability of loss is established, taking into consideration
such factors as the borrower's financial condition, underlying collateral and
guarantees. Loans are also subject to periodic examination by regulatory
agencies. Such agencies may require charge-offs or additions to the allowance
based upon their judgments about information available at the time of their
examination.

   (INFORMATION AS OF AND FOR THE YEAR ENDED DECEMBER 31, 1996 IS UNAUDITED)
 
 
 (f) Income Taxes
 
  The Company and its subsidiary file a consolidated federal income tax
return. The Company records deferred tax assets and liabilities for the future
tax consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective
income tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates applied to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date.
 
 (g) Use of Estimates
 
  Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these consolidated financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.
 
 (h) Consolidated Statements of Cash Flows
 
  For purposes of the consolidated statements of cash flows, cash and cash
equivalents include cash-on-hand and due from banks.
 
  Supplemental information for the consolidated statements of cash flows for
1997 and 1996 was as follows (in thousands):

 (i) Earnings Per Common Share
 
  Earnings per share is computed in accordance with SFAS No. 128, Earnings Per
Share. Basic earnings per share is based upon the weighted average number of
common shares outstanding during the periods presented. Weighted average
common shares outstanding were 12,751 and 12,772 for 1997 and 1996,
respectively. During 1997 and 1996, there were no dilutive securities
outstanding.
 
 (j) Future Accounting Pronouncements
 
  The Financial Accounting Standards Board (FASB) issued SFAS No. 130,
Reporting Comprehensive Income, and SFAS No. 131, Disclosures About Segments
of an Enterprise and Related Information, in June 1997. SFAS No. 130 will
require the Company to classify items of other comprehensive income by their
nature in the financial statements and display the accumulated balance of
other comprehensive income separately from retained earnings and additional
paid-in capital in the equity section of the statement of stockholders'
equity. SFAS No. 131 requires that public enterprises report financial and
descriptive information about their reportable operating segments. Operating
segments are components of an enterprise about which separate financial
information is available that is evaluated regularly by management. Both SFAS
No. 130 and SFAS No. 131 are effective for fiscal years beginning after
December 15, 1997. The adoption of the standards is not expected to have a
significant impact on the financial statements of the Company.

(10) COMMITMENTS
 
  The Company has outstanding commitments to provide loans to customers and
has also issued letters of credit. Loan commitments generally have fixed
expiration dates or other termination clauses and may require payment of a
fee. Since many of the commitments are expected to expire without being drawn
upon, the total commitment amounts do not necessarily represent future cash
requirements. Letters of credit are conditional commitments issued by the
Company to guarantee the performance of a customer to a third party. The
credit risk involved in issuing letters of credit is essentially the same as
is involved in extending loan facilities to customers. The Company has
unfunded loan commitments and outstanding letters of credit amounting to
$3,589,000 and $4,752,000 at December 31, 1997 and 1996, respectively.

personal properties and assets held under lease by Company and Bank are held
by them under valid, subsisting and enforceable leases with such exceptions as
do not interfere with the use made of such properties and assets by Company
and Bank. No consent is necessary under the terms of any such lease in
connection with the consummation of the transactions contemplated hereby.
 
  4.11 Undisclosed Liabilities. As of the date hereof, neither Company nor
Bank have any debt, liability or obligation (whether accrued, contingent,
absolute or otherwise) known to any of such corporations of the nature which
would customarily be included in a corporate balance sheet or the notes
thereto prepared in accordance with generally accepted accounting principles
that is not reflected or reserved against in the Company Financial Statements
or was not incurred in the ordinary course of their business.
 
  4.12 Taxes. The Company and Bank have timely filed all tax returns required

returns and have timely paid all other taxes as are due, except such as are
being contested in good faith by appropriate proceedings and with respect to
which the Company is maintaining reserves adequate for their payment. To the
best knowledge of the Company, the liability for taxes set forth on each such
tax return
 
                                      A-8
<PAGE>
 
adequately reflects the taxes required to be reflected on such tax return.
Neither the IRS nor any other governmental entity or taxing authority or
agency is now asserting, either through audits, administrative proceedings,
court proceedings or otherwise, or, to the best of Company's knowledge,
threatening to assert against Company or Bank any deficiency or claim for
additional taxes. Neither the Company nor Bank has granted any waiver of any
statute of limitations with respect to, or any extension of a period for the
assessment of, any tax. There are no tax liens on any assets of the Company or
Bank. Neither the Company nor Bank has received a ruling or entered into an
agreement with the Internal Revenue Service or any other governmental entity
or taxing authority or agency that would have a Material Adverse Effect (as
defined below) on the Company or Bank, taken as a whole, after the Effective
Time. The Company agrees to provide assistance in the preparation of income
tax returns for the Company and Bank from the commencement of the current
fiscal year through the Effective Time with such returns to be completed
within ninety (90) days of the Effective Time.

all material reports, registrations and statements, together with any
amendments required to be made with respect thereto, with all governmental or
regulatory authorities, agencies, courts, commissions or other entity

in connection therewith. Except for normal examinations conducted by a
Governmental Entity in the regular course of the business of Company and Bank,
no Governmental Entity has initiated any proceeding or, to the best knowledge
of Company, investigation into the business or operations of Company or Bank.
There is no unresolved material violation, criticism, or exception by any
Governmental Entity with respect to any report or statement relating to any
examinations of Company or Bank. Company has provided or made available to
Gold all reports of examinations conducted by any Governmental Entity with
respect to Company and/or Bank, and all correspondence between Company and/or

  or others with whom they have business relationships.
 
    (b) The business affairs of Company and Bank have been conducted and
  carried on only in their ordinary and regular course of business, and
  Company and Bank have not incurred or become subject to
 
                                      A-9
<PAGE>
 
  any liabilities or obligations other than those incurred in their ordinary
  course of business, those incurred pursuant to existing contracts disclosed
  pursuant to Section 4.13 and those incurred pursuant to commitments

  employees or directors, increased the rate of compensation, if any, or
  instituted or made any material increase in any officer's, employee's or
  director's welfare, retirement or similar plan or arrangement, other than
  merit increases made in accordance with past practices and procedures which
  have not exceeded the greater of $3,000 or 5% on an annual basis for any
  one individual.
 
  4.16 Compliance with ERISA. Neither Company nor Bank has established,
maintained or contributed at any time during the five-year period ending as of
the Effective Time to any employee benefit plan (as defined in Sections 3(3)
or 3(37) of the Employment Retirement Income Security Act of 1974 ("ERISA"))
or any other plan with respect to which any governmental filings are required,
except for the plans listed on Schedule 4.16 (collectively, the "Plans"). A
true and accurate copy of each of the Plans, any related trust agreements and
each of the amendments thereto has been provided to Gold together with (i) all
determination letters received in respect of any qualified plans, and (ii) all
required reports and supporting schedules filed with any government agency in
respect of the Plans for the three most recent years ending on or before the
Effective Time. To Company's knowledge as sponsor of the Plans, the Plans and
each fiduciary (as defined in Section 3(21) of ERISA) of the Plans are in
compliance in all material respects with all applicable requirements
(including nondiscrimination requirements in effect as of the Effective Time)
of the Internal Revenue Code of 1986 ("Code"), including, but not limited to,
Sections 79, 105, 106, 125, 401, 501, and 4975 of the Code. For purposes of
this Section 4.16, noncompliance with the Code or ERISA is material if such
noncompliance could have a Material Adverse Effect on the condition of one or
more of the Plans or of Company or Bank, either as of the Effective Time or
upon discovery of the noncompliance. To Company's knowledge as sponsor of the
Plans, all required contributions to the Plans through the Effective Time have
been made. To Company's knowledge as sponsor of the Plans, Company and Bank
(each with respect to the Plans), as well as the Plans, have no material
current or threatened liability of any kind to any person, including but not
limited to any government agency, now or as of the Effective Time, other than
for the payment of benefits in the ordinary course.
 
  4.17 Defaults. Neither Company nor Bank is in material breach or material
default known to either under any agreement or commitment to which the Company
or Bank is a party, or under any loan agreement, note, security agreement,
guarantee or other document pursuant to or in connection with the Company's or
Bank's extension of credit; and to their knowledge there has not occurred any
event which, after the giving of notice, the lapse time or otherwise, would
constitute any such default under, or result in any such breach of, any such
agreement, commitment or extension of credit.
 
  4.18 Insurance. Complete and correct copies of all material policies of
fire, product or other liability, workers' compensation and other similar
forms of insurance owned or held by Company and Bank have been delivered or
made available to Gold. Subject to expirations and renewals of insurance
policies in the ordinary course of business, all such policies are in full
force and effect, all premiums with respect thereto covering all periods up to
and including the date as of which this representation is being made have been
paid (other than retrospective premiums which may be payable with respect to
worker's compensation insurance policies), and no notice of cancellation or
termination has been received with respect to any such policy. Such policies
are and shall remain valid, outstanding and enforceable policies, and will not
be terminated prior to the Effective Time. To the best knowledge of Company,
the insurance policies to which Company or Bank are parties are sufficient for
compliance with all material requirements of law and all material agreements
to which Company or Bank are parties and will be maintained by Company and
Bank until the Effective Time. Neither Company nor Bank has been refused any
insurance with respect to any material assets or operations, nor has coverage
been limited in any respect material to their operations by any insurance
carrier to which they have applied for any such insurance or with which they
have carried insurance during the last five (5) years.

  4.19 Absence of Adverse Agreements. Neither the Company nor Bank is a party
to any agreement or instrument or any judgment, order or decree or any rule or
regulation of any court or other governmental agency or authority which
materially and adversely affects or in the future may have a Material Adverse
Effect on the financial condition, results or operations, assets, business or
prospects of the Company or Bank, taken as a whole.
 
  4.20 Internal Controls and Records. The Company and Bank maintain books of
account which accurately and validly reflect, in all material respects, all
loans, mortgages, collateral and other business transactions and maintain
accounting controls sufficient to ensure that all such transactions are (a) in
all material respects, executed in accordance with its management's general or
specific authorization, and pursuant to Company's and Bank's documented
policies and procedures, and (b) recorded in conformity with generally
accepted accounting principles. Company has furnished to Gold all of Company's
and Bank's written internal policies and procedures which are identified on
the Company's Disclosure Schedule.
 
  4.21 Loans. (a) Bank is not a party to any written or oral loan agreement,
note or borrowing arrangement which has been classified as "substandard",
"doubtful," "loss," "other loans especially mentioned" or any comparable
classifications by Company or Bank or banking regulators, except as reflected
on a list previously provided to Gold and Sub during the due diligence period,
which list Company and Bank agree to update between the date hereof and the
Closing Date; (b) neither Company nor Bank is a party to any written or oral
loan agreement, note, or borrowing arrangement, including any loan guaranty,

corporation or enterprise controlling, controlled by or under common control

Company nor Bank is a party to any written or oral loan agreement, note or
borrowing arrangement in violation of any law, regulation or rule of any

applicable past and present federal, state and local environmental statutes
and regulations and neither the condition of any property owned by Company or
Bank nor the operation of the business of any of such entities violates any
applicable federal, state or local environmental statute or regulation. None
of the operations of Company or Bank is subject to any judicial or
administrative proceeding alleging the violation of any federal, state or
local environmental health or safety statute or regulation nor is it the
subject of any claim alleging damages to health or property pursuant to which
the Company or Bank may be liable. None of the operations of nor any of the
properties owned by Company or Bank is the subject of any federal, state or
local investigation in evaluating whether any remedial action is needed to
respond to a release or threatened release of any hazardous waste or substance
from whatever source. No condition or event has occurred which, with notice or
the passage of time or both, would constitute a violation of any federal,
state or local environmental law and at no time has the Company or Bank stored
or used any pollutants, contaminants or hazardous or toxic waste, substances
or materials on or at any location owned by Company or Bank. There are no
underground storage tanks now or heretofore located on any real property owned
by Company or Bank. Neither Company nor Bank has ever been notified by either
a federal, state or local governmental authority, or any private party, that
Company or Bank is a potentially responsible party for remedial costs spent
addressing the release, or threat of a release, of a hazardous substance and
to the environment pursuant to the Comprehensive Environmental Response,
Compensation or Liability Act, 42 U.S.C. (S)(S) 9601, et seq. or any
corresponding state law.
 
  Gold may obtain at its option and expense on or prior to 120 days following
the date hereof an environmental audit of all properties and assets of Company
and Bank whether directly owned or classified as other real estate owned. Such
environmental audit shall constitute a part of the due diligence process,
should Gold choose to pursue it, and if Gold determines in its sole discretion
that such environmental audit has not been completed to its reasonable
satisfaction or reflects the potential of an environmental problem with
respect to any of the properties or assets of Company or Bank, then Gold may
deem the due diligence unsatisfactory and terminate this Agreement under the
terms of Section 9.1 hereinafter.
 
  4.23 Broker's Fees. Neither Company nor Bank nor any of their respective
officers or directors has employed any broker or finder or incurred any
liability for any broker's fees, commissions or finder's fees in connection
with any of the transactions contemplated by this Agreement.

which it was made, in order to make the statements herein or therein not
misleading.

  9.1 Basis for Termination. This Agreement and the transactions contemplated
hereby may be terminated at any time prior to the Closing Date: (a) by mutual
consent in writing of the parties hereto; (b) by Gold upon written notice to
Company if any regulatory approval of the transactions contemplated under the
terms of this Agreement shall be denied or if any such regulatory approval
shall be conditioned or restricted in any manner which in the reasonable
judgment of Gold would materially adversely affect the operations of or would
be unduly burdensome to Gold; (c) by Gold or Company if the other party has
materially breached this Agreement and has not cured such breach within the
earlier of (i) 30 days after the nonbreaching party shall have given notice to
the breaching party of the existence of such breach or (ii) the Closing Date;
(d) by Gold or Company upon written notice to the other of any other condition
imposed for the benefit of such party that shall not have been satisfied or
waived prior to the Closing Date; or (e) by either Gold or Company if the
Closing Date shall not have occurred by December 31, 1998; provided that the
terminating party is not then in material breach of this Agreement and
provided further that such delay has not been caused by regulatory action or
inaction, whether by banking authorities, the Securities and Exchange
Commission, or otherwise, beyond the control of either party. As used in this
Section 9.1, actions contemplated as being taken by Gold or the Company must
be taken by their respective Board of Directors or the Executive Committee of

hereto shall have any liability to the other of any nature whatsoever,

  In the event Gold and Sub have performed all of their obligations hereunder
and all conditions precedent to the obligation of Gold and Sub to close have
been met or waived in writing by Gold and Sub, but Company fails or otherwise
refuses to close, then Gold shall be entitled to enforce the terms hereof by
an action seeking specific performance. Such right is not exclusive and shall
not preclude Gold from also pursuing an action to recover any and all damages
resulting from the Company's default hereunder. All remedies available to Gold
hereunder or by law are cumulative.

action taken or authorized by their respective Boards of Directors, at any
time before or after approval of the matters presented in connection with the

hereto.
 
  9.4 Extension; Waiver. At any time prior to the Effective Time, the parties
hereto, by action taken or authorized by their respective Board of Directors,

any of the obligations or other acts of the other parties hereto, (b) waive
any inaccuracies in the representations and warranties contained herein or in

party hereto to any such extension or waiver shall be valid only if set forth
in a written instrument signed on behalf of such party.
 
  9.5 Indemnification by Company and its Shareholders. Subsequent to the
closing hereof, the Company and each of its shareholders (as evidenced by
delivery at or prior to closing of the shareholder consent as referenced
hereinabove) jointly and severally agree to indemnify and hold harmless Gold,
Sub and the officers, shareholders and directors of each such entity from and
against and in respect of any and all damages, losses, diminution of value, or
expenses suffered or incurred by any such party (whether as a result of third
party claims [whether valid or not], demands, suits, causes of action,
proceedings, investigations, judgments or liabilities or otherwise), including
costs of investigation in defense and reasonable attorneys' fees assessed,
incurred or sustained by or against any of them, with respect to or arising
out of any breach of the representations, warranties and/or covenants of the
Company set forth herein and in any other agreement or instrument executed by
the Company in connection herewith. If this merger is approved by a requisite
number of shareholders of Company, then each and every shareholder of Company
shall be deemed to have agreed to this indemnification whether or not such
shareholder dissents to the terms of the merger, subject to the limitation set
forth in Section 9.7 hereinafter.
 
  9.6 Indemnification by Gold. Gold agrees to indemnify, defend and hold
harmless Company and its shareholders from and against and in respect of any
and all damages, losses, diminution of value, or expenses suffered or incurred
by Company (whether as a result of third party claims [whether valid or not],
demands, suits, causes of action, proceedings, investigations, judgments,
liabilities or otherwise), including costs of investigation and defense and
reasonable attorneys' fees assessed or incurred or sustained by or against
Company or its shareholders, with respect to or arising out of any breach of
the representations, warranties and covenants of Gold and Sub set forth herein
and in any other agreement or instrument executed by Gold and/or Sub in
connection herewith.
 
  9.7 Limitations on Indemnification. Notwithstanding anything herein
contained to the contrary, no person shall be entitled to indemnification
under the provisions of this Agreement: (i) unless such party shall have given
written notice to the indemnifying party setting forth its claim for
indemnification in reasonable detail, and (ii) to the extent that the
aggregate amount of all indemnification liability under Section 9.5 or Section
9.6, as applicable, exceeds the sum of the total figure reflected in Clause
(i) of Section 2.2(c).
 
  9.8 Procedure for Indemnification. If a party hereto becomes aware of an
event which gives rise to a claim for indemnification hereunder, such party
shall give the other party prompt notice of any such action, claim, liability,
assessment or notice of deficiency received by such party which might result
in any liability under this provision. To the extent Gold is giving such
notice, notice to Company shall be deemed sufficient to constitute
 
                                     A-18
<PAGE>
 
notice to all shareholders. By execution hereof, Company specifically agrees
that it shall assume all responsibility for communicating receipt of any such
notice to the shareholders of Company. Further, any party who may claim a
right of indemnification hereunder agrees to refrain from paying, settling or
compromising any such claim for which indemnification may be sought without
giving notice of same to the other party. If the other party wishes to contest
or defend such third party claim, then the party against whom the claim was
made shall be obligated to cooperate fully with such party in contesting and
preserving all rights with respect to such contest; provided, however, that if
the other party does not wish to challenge or contest such third party claim,
then the party against whom the claim was being made by settle same on terms
and conditions it deems to be the most favorable it can be obtained and then
inserting the indemnification claim against the other party hereto. When
giving a notice under this provision, a party may specify a time for a
response from the other party as to whether such other party wishes to contest
or defend such third party claim. Such deadline for response may be
established consistent with the facts and circumstances surrounding the
situation. Failure of the other party to respond within such time period shall
constitute such other party's decision not to contest or defend such claim. If
a party hereunder claims indemnification for a claim other than a third party
claim, the party seeking indemnification shall notify the indemnifying party
in writing of the basis for such claim setting forth the nature and amount of
the damages resulting from such claim. To the extent a party is deemed to have
ultimately been responsible for indemnification, then interest shall be deemed
to accrue on the unpaid amount of indemnification obligation at the prime rate
of interest announced from time to time by Exchange National Bank, such
interest to be calculated based on the actual number of days elapsed from the
date each indemnification obligation becomes due and owing until paid in full
and based on 365 day year.

                                    ANNEX B
 
  K.S.A. (S) 17-6712. PAYMENT FOR STOCK OF STOCKHOLDER OBJECTING TO MERGER OR
CONSOLIDATION; DEFINITIONS; NOTICE TO OBJECTING STOCKHOLDERS; DEMAND FOR
PAYMENT; APPRAISAL AND DETERMINATION OF VALUE BY DISTRICT COURT, WHEN;
TAXATION OF COSTS; RIGHTS OF OBJECTING STOCKHOLDERS; STATUS OF STOCK; SECTION
INAPPLICABLE TO CERTAIN SHARES OF STOCK. (a) When used in this section, the
word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation.
 
  (b) The corporation surviving or resulting from any merger or consolidation,
within 10 days after the effective date of the merger or consolidation, shall
notify each stockholder of any corporation of this state so merging or
consolidating who objected thereto in writing and whose shares either were not
entitled to vote or were not voted in favor of the merger or consolidation,
and who filed such written objection with the corporation before the taking of
the vote on the merger or consolidation, that the merger or consolidation has
become effective. If any such stockholder, within 20 days after the date of
mailing of the notice, shall demand in writing, from the corporation surviving
or resulting from the merger or consolidation, payment of the value of the
stockholder's stock, the surviving or resulting corporation shall pay to the
stockholder, within 30 days after the expiration of the period of 20 days, the
value of the stockholder's stock on the effective date of the merger or
consolidation, exclusive of any element of value arising from the expectation
or accomplishment of the merger or consolidation.
 
  (c) If during a period of 30 days following the period of 20 days provided
for in subsection (b), the corporation and any such stockholder fail to agree
upon the value of such stock, any such stockholder, or the corporation
surviving or resulting from the merger or consolidation, may demand a
determination of the value of the stock of all such stockholders by an
appraiser or appraisers to be appointed by the district court, by filing a
petition with the court within four months after the expiration of the thirty-
day period.
 
  (d) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the corporation, which shall file with the clerk of
such court, within 10 days after such service, a duly verified list containing
the names and addresses of all stockholders who have demanded payment for
their shares and with whom agreements as to the value of their shares have not
been reached by the corporation. If the petition shall be filed by the
corporation, the petition shall be accompanied by such duly verified list. The
clerk of the court shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the corporation
and to the stockholders shown upon the list at the addresses therein stated
and notice shall also be given by publishing a notice at least once, at least
one week before the day of the hearing, in a newspaper of general circulation
in the county in which the court is located. The court may direct such
additional publication of notice as it deems advisable. The forms of the
notices by mail and by publication shall be approved by the court.
 
  (e) After the hearing on such petition the court shall determine the
stockholders who have complied with the provisions of this section and become
entitled to the valuation of and payment for their shares, and shall appoint
an appraiser or appraisers to determine such value. Any such appraiser may
examine any of the books and records of the corporation or corporations the
stock of which such appraiser is charged with the duty of valuing, and such
appraiser shall make a determination of the value of the shares upon such
investigation as seems proper to the appraiser. The appraiser or appraisers
shall also afford a reasonable opportunity to the parties interested to submit
to the appraiser or appraisers pertinent evidence on the value of the shares.
The appraiser or appraisers, also, shall have the powers and authority
conferred upon masters by K.S. 60-253 and amendments thereto.
 
  (f) The appraiser or appraisers shall determine the value of the stock of
the stockholders adjudged by the court to be entitled to payment therefor and
shall file a report respecting such value in the office of the clerk of
 
                                      B-1
<PAGE>
 
the court, and notice of the filing of such report shall be given by the clerk
of the court to the parties in interest. Such report shall be subject to
exceptions to be heard before the court both upon the law and facts. The court
by its decree shall determine the value of the stock of the stockholders
entitled to payment therefor and shall direct the payment of such value,
together with interest, if any, as hereinafter provided, to the stockholders
entitled thereto by the surviving or resulting corporation. Upon payment of
the judgment by the surviving or resulting corporation, the clerk of the
district court shall surrender to the corporation the certificates of shares
of stock held by the clerk pursuant to subsection (g). The decree may be
enforced as other judgments of the district court may be enforced, whether
such surviving or resulting corporation be a corporation of this state or of
any other state.
 
  (g) At the time of appointing the appraiser or appraisers, the court shall
require the stockholders who hold certificated shares and who demanded payment
for their shares to submit their certificates of stock to the clerk of the
court, to be held by the clerk pending the appraisal proceedings. If any
stockholder fails to comply with such direction, the court shall dismiss the
proceedings as to such stockholder.
 
  (h) The cost of any such appraisal, including a reasonable fee to and the
reasonable expenses of the appraiser, but exclusive of fees of counsel or of
experts retained by any party, shall be determined by the court and taxed upon
the parties to such appraisal or any of them as appears to be equitable,
except that the cost of giving the notice by publication and by registered or
certified mail hereinabove provided for shall be paid by the corporation. The
court, on application of any party in interest, shall determine the amount of
interest, if any, to be paid upon the value of the stock of the stockholders
entitled thereto.
 
  (i) Any stockholder who has demanded payment of the stockholder's stock as
herein provided shall not thereafter be entitled to vote such stock for any
purpose or be entitled to the payment of dividends or other distribution on
the stock, except dividends or other distributions payable to stockholders of
record at a date which is prior to the effective date of the merger or
consolidation, unless the appointment of an appraiser or appraisers shall not
be applied for within the time herein provided, or the proceeding be dismissed
as to such stockholder, or unless such stockholder with the written approval
of the corporation shall deliver to the corporation a written withdrawal of
the stockholder's objections to and an acceptance of the merger or
consolidation, in any of which cases the right of such stockholder to payment
for the stockholder's stock shall cease.
 
  (j) The shares of the surviving or resulting corporation into which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized
and unissued shares of the surviving or resulting corporation.
 
  (k) This section shall not apply to the shares of any class or series of a
class of stock, which, at the record date fixed to determine the stockholders
entitled to receive notice of and to vote at the meeting of stockholders at
which the agreement of merger or consolidation is to be acted on, were either
(1) registered on a national securities exchange or designated as a national
market system security on an interdealer quotation system by the national
association of securities dealers, inc., or (2) held of record by not less
than 2,000 stockholders, unless the articles of incorporation of the
corporation issuing such stock shall otherwise provide; nor shall this section
apply to any of the shares of stock of the constituent corporation surviving a
merger, if the merger did not require for its approval the vote of the
stockholders of the surviving corporation, as provided in subsection (f) of
K.S. 17-6701 and amendments thereto. This subsection shall not be applicable
to the holders of a class or series of a class of stock of a constituent
corporation if under the terms of a merger of consolidation pursuant to K.S.
17-6701 or 17-6702, and amendments thereto, such holders are required to
accept for such stock anything except (i) stock or stock and cash in lieu of
fractional shares of the corporation surviving or resulting from such merger
or consolidation, or (ii) stock or stock and cash in lieu of fractional shares
of any other corporation, which at the record date fixed to determine the
stockholders entitled to receive notice of and to vote at the meeting of
stockholders at which the agreement of merger or consolidation is to be acted
on, were either registered on a national securities exchange or held of record
by not less than 2,000 stockholders, or (iii) a combination of stock or stock
and cash in lieu of fractional shares as set forth in (i) and (ii) of this
subsection.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company Articles and the Company Bylaws require it to indemnify its
directors and officers and advisory directors against liabilities, fines,
penalties, settlements, claims and reasonable expenses incurred by them in
connection with any proceeding to which they may be made a party by reason of
their service in those capacities to the fullest extent permitted by the KGCC.
The KGCC permits a corporation to indemnify its present and former directors
and officers if ordered to do so by a court or after a determination by its
independent counsel, stockholders or a majority of its disinterested directors
that the person to be indemnified acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of
the corporation.

ITEM 22. UNDERTAKINGS
 
  The undersigned registrant hereby undertakes:
 
    (1) That, for the purposes of determining any liability under the
  Securities Act of 1933, each filing of the registrant's annual report
  pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934
  (and, where applicable, each filing of employee benefit plans annual report
  pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
  incorporated by reference in the Registration Statement shall be deemed to
  be a new Registration Statement relating to the securities offered therein,
  and the offering of such securities at the time shall be deemed to be the
  initial bona fide offering thereof.
 
    (2) That, prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this registration
  statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other Items
  of the applicable form.
 
    (3) That, every prospectus (i) that is filed pursuant to paragraph (2)
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Act and is used in connection with an offering of
  securities subject to Rule 415 (section 230.415 of this chapter), will be
  filed as part of an amendment of the registration statement and will not be
  used until such amendment is effective, and that, for purposes of
  determining any liability under the Securities Act of 1933, each such post-
  effective amendment shall be deemed to be a new registration statement
  relating to the securities offered therein, and the offering of such
  securities at that time shall be deemed to be the initial bona fide
  offering thereof.
 
    (4) To respond to requests for information that is incorporated by
  reference into the Prospectus pursuant to Items 4, 10(b), 11 or 13 of this
  Form, within one business day of receipt of such request, and to send the
  incorporated documents by first class mail or other equally prompt means.
  This includes information contained in documents filed subsequent to the
  effective date of the Registration Statement through the date of responding
  to the request.
 
    (5) To supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in the Registration Statement when
  it became effective.

  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is
therefore unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of registrant in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.

                                     __________, 1998
 
Gold Banc Corporation, Inc.
11301 Nall Avenue
Leawood, Kansas 66211
 
Ladies and Gentlemen:
 
  We have acted as counsel to Gold Banc Corporation, Inc., a Kansas
corporation ("the Company"), in connection with the transactions contemplated
by the Restated Agreement and Plan of Reorganization, dated as of April 29,
1998 (the "Agreement"), by and among the Company, Gold Banc Acquisition
Corporation II, Inc. ("Sub") and Tri-County Bancshares, Inc. ("Tri-County").
 
  This opinion is being furnished in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the
"Securities Act").
 
  Pursuant to the Agreement, Tri-County will be merged with and into Sub, with
Sub being the surviving corporation (the "Merger"). In the Merger, the
outstanding shares of common stock, $100.00 par value of Tri-County, other
than any shares owned by the Company, Sub or Tri-County (which shares will be
canceled), will be exchanged for fully paid and nonassessable shares of common
stock, $1.00 par value, of the Company (the "Company Common Stock").
 
  In connection with the transactions contemplated by the Agreement, the
Company will file with the Securities and Exchange Commission (the
"Commission") a Registration Statement on Form S-4 (the "Registration
Statement") relating to the registration under the Securities Act of the
shares of the Company Common Stock to be issued in the Merger.
 
  In connection with this opinion, we have examined and are familiar with
originals or copies, certified or otherwise identified to our satisfaction, of
(i) the Registration Statement, (ii) the Articles of Incorporation and By-laws
of the Company, as in effect on the date hereof, (iii) the Agreement and (iv)
certain resolutions of the Board of Directors of the Company relating to the
Merger. We have also examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents as we have deemed necessary
or appropriate as a basis for the opinions set forth herein.
 
  In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the completeness and authenticity
of all documents submitted to us as originals, the conformity to original
documents of all documents submitted to us as certified or photostatic copies
and the completeness and authenticity of the originals of such latter
documents. In making our examination of documents executed by parties other
than the Company, we have assumed that such parties had the power, corporate
or other, to enter into and perform all obligations thereunder and have also
assumed the due authorization by all requisite action, corporate or other, and
execution and delivery by such parties of such documents on such parties. As
to any facts material to the opinion expressed herein which were not
independently established or verified, we have relied upon oral or written
statements and representations of officers and other representations of the
Company and others.
 
  Members of our firm are admitted to the Bar in the State of Kansas, and we
do not express any opinion as to the laws of any other jurisdiction.
 
  Based upon and subject to the foregoing, we are of the opinion that the
shares of the Company Common Stock, when issued upon the consummation of the
Merger in accordance with the terms of the Agreement and as set forth in the
Registration Statement, will be validly issued, fully paid and nonassessable.
 
<PAGE>
 
  We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement and to the reference to our firm under
the heading "Legal Opinion" in the related Prospectus/Proxy Statement which
forms a part of the Registration Statement. In giving such consent we do not
thereby admit or imply that we are in the category of persons whose consent is
required under Section 7 of the Securities Act or the rules and regulations of
the Commission thereunder.
 
                                          Very truly yours,

Gold Banc Acquisition Corporation, Inc.
11301 Nall
Leawood, KS 66211
Attn.: Mr. Michael W. Gullion, President
 
 RE: Agreement with Tri-County Bancshares, Inc.
 
Ladies and Gentlemen:
 
  We have acted as counsel to Gold Banc Acquisition Corporation II, Inc.
("Gold Banc Acquisition II") and to Gold Banc Corporation, Inc. ("Gold") in
connection with the acquisition by Gold Banc Acquisition II of all of the
issued and outstanding shares of stock of Tri-County Bancshares, Inc. ("Tri-
County") under and pursuant to that certain Restated Agreement and Plan of
Reorganization dated April 28, 1998 (the "Agreement"). Pursuant to Section
7.11 of the Agreement, a condition precedent to the obligation of Gold and
Gold Banc Acquisition to close the transaction described in the Agreement is
that Gold shall have received an opinion of counsel that the transaction
described in the Agreement will be treated as a tax-free reorganization under
Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the
"Code").
 
  In connection with this transaction, we have reviewed the following
documents:
 
    i. The Agreement.
 
    ii. The Certificate of Merger dated            , 1998 (the "Certificate
  of Merger") executed by authorized representatives of Gold Banc Acquisition
  II and Tri-County.
 
    iii. Minutes of certain meetings of the Board of Directors of Gold, Gold
  Banc Acquisition II and Tri-County.
 
    iv. Minutes of certain meetings of shareholders of Gold Banc Acquisition
  II and Tri-County.
 
    v. Articles of Incorporation and Bylaws of Gold.
 
    vi. Articles of Incorporation and Bylaws of Gold Banc Acquisition II.
 
    vii. Articles of Incorporation and Bylaws of Tri-County.
 
  We have also reviewed such other records and documents as we deem pertinent
in rendering the opinion described herein.
 
  In rendering this opinion, we have made, with your consent and without
independent investigation on our part, the following assumptions:
 
    1. All documents executed by all parties to the Agreement have been duly
  and properly authorized, executed, attested, delivered and accepted.
 
    2. All documents submitted to us as copies conform to the original
  documents, and all such originals are authentic.
 
    3. There are no oral agreements or other written documents or course of
  conduct which may modify the terms of the Agreement or the Certificate of
  Merger.
 
    4. Gold Banc Acquisition II, as a result of the consummation of the
  transaction described in the Agreement, will ultimately acquire
  substantially all of the properties of Tri-County.
 
    5. There is no consideration being provided by Gold Banc Acquisition II
  pursuant to the Agreement other than stock of Gold (except for certain cash
  payments required by the Agreement and subject to rights of dissenting
  shareholders of Tri-County pursuant to K.S.A. 17-6712). No stock of Gold
  Banc Acquisition
<PAGE>
 
  II is being used as consideration for this transaction. Gold Banc
  Acquisition II is assuming no liabilities of Tri-County except as set forth
  in the Agreement.
 
    6. All representations and warranties of all parties to the Agreement as
  set forth therein are true, accurate and complete.
 
    7. The Certificate of Merger will be filed on a timely basis with the
  Kansas Secretary of State and recorded in the office of the Register of
  Deeds of each county in which the registered office of Gold, Gold Banc
  Acquisition II and Tri-County respectively is located.
 
    8. The shareholders of Tri-County have no preconceived plan or
  arrangement to dispose of a significant percentage of the stock in Gold
  being acquired pursuant to the transaction described in the Agreement.
 
    9. Gold and Gold Banc Acquisition II will continue Tri-County's historic
  business or will use a significant portion of Tri-County's historic
  business assets in continuing such business.
 
    10. The primary motivation to Gold and Gold Banc Acquisition II in
  consummating this transaction is to acquire the business operations of Tri-
  County and not to avoid income tax.
 
    11. There is no plan to immediately liquidate Gold Banc Acquisition II
  after the closing of the transaction described in the Agreement.
 
  Based upon the foregoing and subject to the assumptions, qualifications and
limitations set forth herein, it is our opinion that the transaction described
in the Agreement will be treated as a tax-free reorganization as that term is
used in Section 368(a)(1)(A) of the Code. This opinion does not address any
issue applicable to carryover of tax attributes as governed by Section 381 of
the Code. Further, this opinion does not address additional requirements
imposed upon the parties to the Agreement to file documentation with federal
income tax returns in the year in which such transaction closes, nor does this
opinion address the issue of basis of any asset acquired by any party to the
transaction.
 
  The opinion expressed herein is restricted to matters governed by the laws
of the United States of America and the laws of the State of Kansas as they
exist as of the date of this letter. To the extent there is any change in the
federal income tax laws after this date, no opinion is expressed as to the
impact of such change on the tax treatment of the transaction described in the
Agreement. Further, to the extent the laws of the State of Kansas change after
this date with respect to the steps required to consummate a merger, this
opinion does not address the impact of such changes upon the income tax
treatment of the transaction described in the Agreement. We undertake no
obligation or responsibility to update or supplement this opinion in response
to subsequent changes in the law or any subsequent changes in the relevant
factual circumstances pertaining to the transaction described in the
Agreement.
 
  The opinion expressed herein is being delivered to you for your sole use and
benefit in connection with the transaction described in the Agreement. This
opinion may not be relied upon by any other person and may not be used in
whole or in part for any other purpose or delivered to any other person except
with the prior written consent of the undersigned.
 
                                          Yours very truly,
 
                                          /s/ Thomas K. Jones
