Dear Stockholder:

         You are invited to attend a special meeting of stockholders (the
"Special Meeting") of First National Bank Shares, LTD. ("First National") to be
held at Suite 2800, 1201 Walnut Street, Kansas City, Missouri, on Friday,
January 30, 1998 at 10:00 a.m., local time. Notice of the Special Meeting, a
Prospectus/Proxy Statement and a Proxy Card are enclosed.

         The Special Meeting has been called in connection with the proposed
acquisition of First National and its wholly owned savings institution
subsidiary, First United National Bank and Trust Company ("First United"), by
Commercial Federal Corporation ("Commercial") and its principal subsidiary,
Commercial Federal Bank, a Federal Savings Bank (the "Bank"), respectively, in
accordance with the Reorganization and Merger Agreement dated as of September
11, 1997 by and among Commercial, the Bank, First National and First United (the
"Merger Agreement"). Pursuant to the Merger Agreement (1) First National will
merge into Commercial and each outstanding share of First National's common
stock will be converted into the right to receive shares of Commercial common
stock and cash in lieu of fractional shares, based upon an exchange ratio as
more fully described in the accompanying Prospectus/Proxy Statement and (2)
First United will merge with and into the Bank (collectively, the "Merger").

         Following the Merger, Commercial will be the resulting holding company,
and the Bank will be the resulting subsidiary institution. Consummation of the
Merger is conditioned upon, among other things, receipt of all required
regulatory approvals and approval by First National's stockholders.

         At the Special Meeting, stockholders of First National will consider
and vote upon approval of the Acquisition Merger and the Merger Agreement. Your
Board of Directors has approved the Merger Agreement, including the Acquisition
Merger, and believes that the Acquisition Merger and the Merger Agreement are in
the best interests of First National and its stockholders. Accordingly, your
Board of Directors unanimously recommends that you vote FOR approval of the
Acquisition Merger and the Merger Agreement.

         You are urged to read the accompanying Prospectus/Proxy Statement,
which provides detailed information concerning the Merger and related matters.

         Your vote is important, regardless of the number of shares you own. ON
BEHALF OF THE BOARD OF DIRECTORS, I URGE YOU TO SIGN, DATE AND RETURN THE
ENCLOSED PROXY CARD AS SOON AS POSSIBLE EVEN IF YOU CURRENTLY PLAN TO ATTEND THE
SPECIAL MEETING. This will not prevent you from voting in person but will assure
that your vote is counted if you are unable to attend the Special Meeting.

                                            Sincerely,



                                            J. Thomas Burcham

                         COMMERCIAL FEDERAL CORPORATION
                                   Prospectus
                         992,857 Shares of Common Stock
                            par value $.01 per share

                        FIRST NATIONAL BANK SHARES, LTD.
                                 Proxy Statement
                       For Special Meeting of Stockholders
                         To Be Held on January 30, 1998
                       -----------------------------------

         This Prospectus/Proxy Statement is being furnished to the holders of
the common stock, par value $1.00 per share ("First National Common Stock") of
First National Bank Shares, LTD. ("First National") in connection with the
solicitation of proxies by the Company's Board of Directors for use at its
special meeting of stockholders (the "Special Meeting") to be held at Suite
2800, 1201 Walnut Street, Kansas City, Missouri, on Friday, January 30, 1998 at
10:00 a.m., local time.

         The purposes of the Special Meeting and the matters to be acted upon
are to consider and vote upon the proposed merger of First National into
Commercial Federal Corporation ("Commercial"), with Commercial as the surviving
corporation (the "Acquisition Merger"), in accordance with a Reorganization and
Merger Agreement by and among Commercial; Commercial Federal Bank, a Federal
Savings Bank (the "Bank"), the wholly-owned savings institution subsidiary of
Commercial; First National; and First United National Bank and Trust Company
("First United"), the wholly-owned savings institution subsidiary of First
National, dated September 11, 1997 (the "Merger Agreement"), which sets forth
the terms and conditions of the Acquisition Merger and also provides for the
subsequent merger of First United into the Bank (the "Bank Merger" and,
together, with the Acquisition Merger, the "Merger"); and (ii) to consider and
vote upon such other business as may properly come before the Special Meeting or
any adjournments thereof.

         Pursuant to the Merger Agreement, each share of First National Common
Stock outstanding at the effective time of the Acquisition Merger (the
"Acquisition Merger Effective Time") (other than shares owned or held by First
National or Commercial or any of their subsidiaries (other than in any 401(k)
plan or in a fiduciary capacity) or shares the holders which have perfected
dissenters' rights of appraisal "Dissenting Shares")) will be converted into the
right to receive a number of shares of Commercial common stock, par value $.01
per share (the "Commercial Common Stock") (such number of shares referred to as
the "Exchange Ratio") based upon the "Average NYSE Closing Price" of Commercial
Common Stock (i.e., the arithmetic mean of the per share closing price of the
Commercial Common Stock as reported on the New York Stock Exchange ("NYSE") for
the twenty-fifth through sixth trading day, inclusive, immediately preceding the
business day prior to the later of (A) the date on which all requisite
regulatory approvals have been obtained, including the expiration of any related
waiting periods, or (B) the date First National obtains stockholder approval of
the Merger Agreement (the "Determination Period")) as follows: (i) if the
Average NYSE Closing Price is equal to or greater than $24.00, but equal to or
less than $28.00, the Exchange Ratio shall be that number of shares of
Commercial Common Stock equal to the quotient that results by dividing the "Per
Share Purchase Price" (as defined below) by the Average NYSE Closing Price; (ii)
if the Average NYSE Closing Price is greater than $28.00, the Exchange Ratio
shall be the quotient that results from dividing the "Per Share Purchase Price"
by $28.00; and (iii) if the Average NYSE Closing Price is less than $24.00, the
Exchange Ratio shall be the quotient that results from dividing the "Per Share
Purchase Price" by $24.00.
<PAGE>
 
         The term "Per Share Purchase Price" shall be equal to the quotient that
results by dividing (i) the "Aggregate Purchase Price" the number of shares
outstanding at Closing. The term "Aggregate Purchase Price" is defined in the
Merger Agreement to equal to $27,800,000, plus (A) the amount of cash held
                                          ----
directly by First National as of the Acquisition Merger Effective Time as
reflected on its books and records and (B) any amounts recorded as a receivable
by First National on its books and records from First United and Missouri Bank &
Trust Company (the "Missouri Bank") and their subsidiaries pursuant to First
National's income tax sharing agreements with these banks, less (C) the amount
                                                           ----
of federal and state income tax liability (to the extent not paid prior to the
Closing) and net of receivables from the Internal Revenue Service attributable
to the taxable gain, if any, realized on the spin-off of shares of the Missouri
Bank and the sale of certain other assets, (D) the amount of any dividends
declared or paid by First United since June 30, 1997, (E) the amount of any fee
paid or payable by First United or payable by First National to any broker or
advisor or similar party whether to Friedman, Billings Ramsey & Co., Inc. or
otherwise and (F) all other liabilities (including federal and state income tax
liability of First National and its subsidiaries (to the extent not consolidated
with First National)), together with any accrued but unpaid interest, of First
National as reflected or required to be reflected under generally accepted
accounting principles on its books and records as of the Closing.

         Pursuant to the terms of the Merger Agreement, First National has
agreed to satisfy all of First National's liabilities (with the exception of tax
liabilities) prior to Closing. First National has further agreed that the amount
of cash it has as of the Acquisition Merger Effective Time plus any amounts
receivable from the Internal Revenue Service to be not less than the amount of
any unpaid federal and state income tax liabilities of First National whether
due or not yet due. On November 19, 1997, all of First National's stockholders
entered into an Agreement among Stockholders which provides for, among other
things, the sale and issuance of additional shares of First National Common
Stock, the proceeds of which will be used to satisfy First National's
liabilities as of the Acquisition Merger Effective Time. As such, First National
does not anticipate that there will be any adjustments (upward or downward) of
the Aggregate Purchase Price. It is currently anticipated that a maximum of
18,044 shares of First National Common Stock will be outstanding at the
Acquisition Merger Effective Time. Based on an Aggregate Purchase Price of $27.8
million, a total of 18,044 shares of First National Common Stock outstanding at
the Acquisition Merger Effective Time and the closing price per share of
Commercial Common Stock on the NYSE on January 5, 1998, of $35.125, each share
of First National Common Stock would be exchanged for 55.0242 shares of
Commercial Common Stock. The actual number of shares to be received for each
share of First National Common Stock at the Acquisition Merger Effective Time
will vary from this amount should any of these assumptions change. In all cases,
cash will be paid in lieu of fractional shares.

         The number of shares of Commercial Common Stock to be received by First
National stockholders, the Average NYSE Closing Price, as well as all per share
data included herein with respect to Commercial have been adjusted to reflect a
three-for-two stock split effected in the form of a 50% stock dividend declared
by Commercial on November 17, 1997 and distributed on December 15, 1997 to
stockholders of record as of November 28, 1997. Fractional shares resulting from
the stock split were paid in cash.

         Commercial has filed a registration statement on Form S-4 with the
Securities and Exchange Commission (the "Commission") pursuant to the Securities
Act of 1933, as amended (the "Securities Act"), with respect to the shares of
the Commercial Common Stock to be issued upon consummation of the Acquisition
Merger. See "Available Information." This Prospectus/Proxy Statement constitutes
a prospectus of Commercial with respect to the issuance of shares of Commercial
Common Stock to the stockholders of First National upon consummation of the
Acquisition Merger.

         THE BOARD OF DIRECTORS OF FIRST NATIONAL BELIEVES THAT THE ACQUISITION
MERGER IS IN THE BEST INTERESTS OF FIRST NATIONAL'S STOCKHOLDERS AND UNANIMOUSLY
RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE ACQUISITION MERGER,
INCLUDING THE MERGER AGREEMENT.

         THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
SECURITIES AND EXCHANGE COMMISSION, THE OFFICE OF THRIFT SUPERVISION, THE
FEDERAL RESERVE, THE OFFICE OF THE COMPTROLLER OF THE CURRENCY, THE FEDERAL
DEPOSIT INSURANCE 
<PAGE>
 
CORPORATION OR ANY STATE AGENCY, NOR HAS SUCH COMMISSION, OFFICE, CORPORATION OR
AGENCY PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS/PROXY STATEMENT.
ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

         THE SHARES OFFERED HEREBY ARE NOT SAVINGS ACCOUNTS OR DEPOSITS AND ARE
NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION.

         This Prospectus/Proxy Statement and the accompanying proxy card are
first being sent to the stockholders of First National on or about January 9,
1998.

         This Prospectus/Proxy Statement does not cover any resales of the
Commercial Common Stock offered hereby to be received by the stockholders deemed
to be affiliates of Commercial or First National upon consummation of the
Merger. No person is authorized to make use of this Prospectus/Proxy Statement
in connection with such resales, although such securities may be traded without
the use of this Proxy Statement/Prospectus by those stockholders of Commercial
not deemed to be affiliates of Commercial or First National.

         The date of this Prospectus/Proxy Statement is January 9, 1998

         For additional information, see "Information Concerning the Special
Meeting" herein.

The Parties to the Merger

         Commercial Federal Corporation and Commercial Federal Bank, a Federal
Savings Bank. Commercial is a unitary non-diversified savings and loan holding
company whose primary asset is the Bank, which is one of the largest depository
institutions in the Midwest. At September 30, 1997, Commercial had total assets
of $7.2 billion and total stockholders' equity of $444.3 million. Based upon
total assets at that date, Commercial was the 13th largest publicly held thrift
holding company in the United States. Commercial is a consumer-oriented
financial institution that emphasizes single-family residential and construction
real estate lending, consumer lending, commercial real estate lending, retail
deposit activities, including demand deposit accounts, and mortgage banking. At
November 30, 1997, Commercial operated 34 branch offices in Nebraska, 21 branch
offices in greater metropolitan Denver, Colorado, 19 branch offices in Oklahoma,
27 branch offices in Kansas and seven branch offices in Iowa. Throughout its 110
year history, Commercial has emphasized customer service. To serve its
customers, Commercial conducts loan origination activities through its 108
branch office network, loan offices of its wholly-owned mortgage banking
subsidiary and a nationwide correspondent network consisting of mortgage loan
originators. Commercial also provides insurance and securities brokerage and
other retail financial services.

         Commercial's strategy for growth emphasizes both internal and external
growth. Operations focus on increasing deposits, including demand accounts,
making loans (primarily single-family mortgage and consumer loans), community
banking, and providing customers with a full array of financial products and a
high level of customer service. As part of its long-term strategic plan,
Commercial intends to expand its operations within its market areas either
through direct marketing efforts aimed at increasing market share, branch
expansions, or opening additional branches. Commercial's retail strategy will
continue to be centered on attracting new customers and selling both new and
existing customers multiple products and services. Additionally, Commercial will
continue to build and leverage an infrastructure designed to increase fee and
other income.

         Complementing its strategy of internal growth, Commercial continues to
grow its present five-state franchise through an ongoing program of selective
acquisitions of other financial institutions. Future acquisition candidates will
be selected based on the extent to which the candidates can enhance Commercial's
retail presence in new or underserved markets and complement Commercial's
existing retail network.

         Commercial's principal executive offices are located at 2120 South 72nd
Street, Omaha, Nebraska 68124, and its telephone number is (402) 554-9200.

         First National Bank Shares, Ltd. and First United Bank and Trust

stock of First United National Bank and Trust Company, a national bank ("First
United") headquartered in Great Bend, Kansas. First National, through First

with funds generated from operations, in agricultural loans, commercial loans,
consumer loans and various types of real estate loans including loans secured by
one to four-family residential properties and commercial properties.

         Prior to November 20, 1997, First National also owned all of the
capital stock of Missouri Bank & Trust Company (the "Missouri Bank). On November
20, 1997, all of the capital stock of the Missouri Bank was distributed to the
stockholders of First National (the "Spin Off"). All financial statements and
financial data included herein reflect only the assets of First National and
First United on a combined basis. At September 30, 1997, First National and
First United, on a combined basis, had total assets of $150.7 million and total
stockholders' equity of $8.4 million.

First National and First United included elsewhere herein.

The Merger

         General. The Merger Agreement provides for the acquisition of First
National by Commercial, and the subsequent merger of First United into the Bank,
as follows: (i) First National will merge into Commercial, with Commercial as
the surviving corporation, pursuant to which the outstanding shares of First
National Common Stock (other than shares owned or held by First National (other
than in any 401(k) Plan or in a fiduciary capacity), shares held by Commercial
or Dissenting Shares will be converted into shares of Commercial Common Stock as
set forth below under " -- Conversion of First National Common Stock" (the
"Acquisition Merger"); and (ii) First United will, following the Acquisition
Merger, merge into the Bank, with the Bank as the surviving savings institution
(the "Bank Merger"). At the Acquisition Merger Effective Time, First National
will have merged into Commercial. Upon the consummation of the Bank Merger (the
"Bank Merger Effective Time"), First United will have merged into the Bank,
Commercial will be the resulting savings institution holding company, and the
Bank will be the resulting subsidiary institution. It is anticipated that the
Bank Merger Effective Time will occur immediately following the Acquisition
Merger Effective Time.

         The Board of Directors of First National considered the Merger and the
terms of the Merger Agreement, including the Exchange Ratio, in light of
economic, financial, legal, market and other factors and concluded that the
Merger is in the best interests of First National and its stockholders. The
Board of Directors of First National recommends that First National's
stockholders vote FOR approval of the Merger Agreement and the Acquisition
Merger.

         For additional information, see "The Merger -- General," "-- Background
of the Merger" and "-- Reasons for the Merger and Recommendations of the First
National Board of Directors" herein and the Merger Agreement attached as Annex A
hereto.

         Conversion of First National Common Stock. Pursuant to the Merger
Agreement, each share of First National Common Stock issued and outstanding at
the Acquisition Merger Effective Time (other than shares owned by First 


                                     (iv)
<PAGE>
 
National or Commercial or their subsidiaries (other than in a 401(k) plan or in
a fiduciary capacity) or Dissenting Shares)) will be converted into and
represent solely the right to receive a number of shares of Commercial Common
Stock (such number of shares referred to as the "Exchange Ratio") based upon the
Average NYSE Closing Price of Commercial Common Stock as follows: (i) if the
Average NYSE Closing Price is equal to or greater than $24.00 but equal to or
less than $28.00, then the Exchange Ratio shall be such number of shares of
Commercial Common Stock equal to the quotient (carried to four digits and
rounded down) that results by dividing the Per Share Purchase Price by the
Average NYSE Closing Price of Commercial Common Stock; (ii) if the Average NYSE
Closing Price is greater than $28.00, the Exchange Ratio shall be the quotient
that results from dividing the Per Share Purchase Price by $28.00; (iii) if the
Average NYSE Closing Price is less than $24.00, then the Exchange Ratio shall be
the quotient that results from dividing the Per Share Purchase Price by $24.00.

         Pursuant to the terms of the Merger Agreement, the Aggregate Purchase
Price is $27.8 million, subject to adjustment, both upward and downward, in
certain circumstances. On November 19, 1997, all of First National's
stockholders entered into an Agreement among Stockholders which provides for,
among other things, the sale and issuance of additional shares of First National
Common Stock, the proceeds of which will be used to satisfy First National's
liabilities as of the Acquisition Merger Effective Time. As such, First National
does not anticipate that there will be any adjustments (upward or downward) of
the Aggregate Purchase Price. It is currently anticipated that a maximum of
18,044 shares of First National Common Stock will be outstanding at the
Acquisition Merger Effective Time. Based on an Aggregate Purchase Price of $27.8
million, a total of 18,044 shares of First National Common Stock outstanding at
the Acquisition Merger Effective Time and the closing price per share of
Commercial Common Stock on the NYSE on January 5, 1998, of $35.125, each share
of First National Common Stock would be exchanged for 55.0242 shares of
Commercial Common Stock. The actual number of shares to be received for each
share of First National Common Stock at the Acquisition Merger Effective Time
will vary from this amount should any of these assumptions change. In all cases,
cash will be paid in lieu of fractional shares.

         The number of shares of Commercial Common Stock to be received by First
National stockholders, the Average NYSE Closing Price, as well as all per share
data included herein with respect to Commercial have been adjusted to reflect a
three-for-two stock split effected in the form of a 50% stock dividend declared
by Commercial on November 17, 1997 and distributed on December 15, 1997 to
stockholders of record as of November 28, 1997. Fractional shares resulting from
the stock split were paid in cash.

         Exchange of Stock Certificates. Prior to the Acquisition Merger
Effective Time, Commercial will appoint an exchange agent (the "Exchange Agent")
to effect the exchange of stock certificates in connection with the Acquisition
Merger. As soon as practicable after the Acquisition Merger Effective Time, the
Exchange Agent will send a notice and letter of transmittal to each First
National stockholder of record at such date advising such stockholder of the
effectiveness of the Acquisition Merger and the procedure for surrendering to
the Exchange Agent outstanding certificates formerly evidencing First National
Common Stock in exchange for new certificates of Commercial Common Stock and
cash in lieu of fractional shares. Promptly following receipt of such notice and
transmittal form, holders of First National Common Stock certificates should
surrender their certificates in accordance with the specified procedures. Upon
surrender, each First National Common Stock certificate will be canceled. See
"The Merger -- Conversion of First National Common Stock -- Exchange of First
National Stock Certificates."

         Dissenters' Appraisal Rights. Under Kansas law, stockholders of First
National who object to the Acquisition Merger have the statutory right to demand
payment of the "fair value" of their First National Common Stock in cash. To
perfect this right, a First National stockholder must (i) not vote his or her
shares in favor of the Merger Agreement and the Acquisition Merger at the
Special Meeting and (ii) must take such action as is required by the provisions
of Section 17-6712 of the Kansas General Corporation Code ("KGCC"), including
delivering written notice of objection to First National prior to the vote on
the Merger Agreement and the Acquisition Merger at the Special Meeting.
Commercial has conditioned its obligation to consummate the Acquisition Merger
on, among other items, no First National stockholders having elected their
dissenter and appraisal rights. See "The Merger -- Dissenters' Rights of
Appraisal" and Annex B hereto. See "The Merger -- Dissenters' Rights of
Appraisal."



                                      (v)
<PAGE>
 
         Voting Agreement. Concurrent with the execution of the Merger
Agreement, J. Thomas Burcham, Chairman of the Board of First National entered
into an agreement with Commercial (the "Voting Agreement") to vote his shares of
First National Common Stock in favor of the Merger Agreement and the Acquisition
Merger. The Voting Agreement covers the shares of First National Common Stock
beneficially owned by Mr. Burcham as of September 11, 1997, as well as any
shares subsequently acquired. A total of 11,168.412 shares of First National
Common Stock (a total of 72.91% of the shares outstanding as of the Record Date)
are covered by the Voting Agreement. See "The Merger -- Voting Agreement."

         Conditions to the Merger. The obligations of Commercial and First
National to effect the Acquisition Merger are jointly subject to a number of
conditions including, among other things, the receipt of First National
stockholder and regulatory approval of the Acquisition Merger and the Bank
Mergers and receipt of an opinion with respect to the tax effects of the Merger.
For additional information, see "The Merger -- Conditions to Consummation of the
Merger" herein.

         Required Regulatory Approvals. The Merger is subject to the approval of
the Office of Thrift Supervision ("OTS") and the Office of the Comptroller of
the Currency ("OCC"). Further the parties are required to notify the Board of
Governors of the Federal Reserve System ("FRB") of the Merger. Following such
approvals of the Merger, the U.S. Department of Justice may review the Merger
and raise objections on antitrust grounds, though objections on such grounds are
not expected. For additional information, see "The Merger -- Required Regulatory
Approvals" herein.

         Termination of the Merger. The Merger Agreement may be terminated at
any time before the Acquisition Merger Effective Time, whether before or after
approval by First National stockholders, in a number of circumstances,
including: (a) by mutual consent of the parties; (b) at the election of either
party, if the closing of the Merger shall not have occurred on or before June
30, 1998; (c) by either party upon the occurrence of an event which renders
satisfaction of one or more of the conditions to the obligations of the other
party impossible; or (d) by First National in certain circumstances at any time
during the two business days commencing on the business day immediately
following the end of the Determination Period, if the Average NYSE Closing Price
of Commercial Common Stock is below certain prescribed levels as described
herein. In the event the Merger Agreement is terminated by First National and,
prior to such termination, a "Termination Event" (as such term is defined
herein) has occurred, First National will be obligated to pay a termination fee
in the amount of $1.0 million and an additional amount equal to reasonable
expenses incurred by Commercial relating to the Merger Agreement and the
transactions contemplated thereby. For additional information, see "The Merger
- -- Amendment or Termination of the Merger Agreement" and "-- Termination Fee"
herein.

         No Solicitation. The Merger Agreement provides that First National will
not authorize or permit any representative of First National or any subsidiary
to initiate contact with any person or entity in an effort to solicit, initiate
or encourage any "takeover proposal" (generally, any bona fide proposal other
than as contemplated by the Merger Agreement, for a merger or other business
combination involving First National, for the acquisition of a 10.0% or greater
equity interest in First National or for the acquisition of a substantial
portion of the assets of First National). In addition, First National may not
(or authorize any representative to): (i) cooperate with, or furnish, or cause
to be furnished, any non-public information concerning First National's
business, properties or assets to any person or entity in connection with any
takeover proposal; (ii) negotiate any takeover proposal with any person or
entity; or (iii) enter into any agreement, letter of intent or agreement in
principle as to any takeover proposal.

         Interests of Certain Persons in the Merger. Certain members of First
National's management and Board of Directors have interests in the Acquisition
Merger in addition to their interests as stockholders of First National
generally. Those interests relate to, among other things, officer's severance,
change-in-control provisions and provisions in the Merger Agreement regarding
indemnification and director and officer insurance information.

         For additional information, see "The Merger -- Management after the
Merger," "-- Employee Benefit Plans after the Merger" and "-- Interests of
Certain Persons in the Merger" herein.

                                     (iv)
<PAGE>
 
         Federal Income Tax Consequences. Commercial and First National will
rely upon an opinion of Deloitte & Touche LLP, tax advisor to Commercial, to the
effect that, among other things, (i) the Acquisition Merger should be treated
for federal income tax purposes as a tax-free reorganization under Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code"); and (ii)
the gain, if any, to be realized by a First National stockholder who receives
Commercial Common Stock in exchange for First National Common Stock should be
recognized, but not in excess of the amount of cash received. For additional
information, see "The Merger -- Federal Income Tax Consequences" herein.

         Accounting Treatment. The Merger will be accounted for under the
purchase method of accounting in accordance with generally accepted accounting
principles, resulting in adjustments to the carrying value of First National's
assets and liabilities to reflect their fair values at the date of the
Acquisition Merger.

Comparison of Stockholder Rights

         Upon consummation of the Merger, holders of First National Common
Stock, whose rights are presently governed by Kansas law and First National's
articles of incorporation and bylaws, and indirectly, First United's charter and
bylaws, will become stockholders of Commercial, a Nebraska corporation.
Accordingly, their rights will be governed by Nebraska law and the articles of
incorporation and bylaws of Commercial and indirectly by the Bank's charter and
bylaws. Certain differences arise from the differences between Kansas and
Nebraska law, between the articles of incorporation and bylaws of First National
and the articles of incorporation and bylaws of Commercial and between the
charter and bylaws of First United and the Bank, including, among other things,
the number of authorized shares of capital stock, the calling of special
meetings of stockholders, the number and term of directors, advance notice
requirements for nominations of directors and presentation of new business at
annual or special meetings of stockholders, preemptive rights, removal of
directors, action of stockholders without a meeting, approval requirements for
business combinations and amendment of corporate governing documents. In
addition, Commercial has in effect a shareholder rights plan. For additional
information, see "Comparison of Stockholder Rights" herein.

                 SUMMARY CONSOLIDATED FINANCIAL INFORMATION OF
                        COMMERCIAL FEDERAL CORPORATION

         The following summary consolidated financial data of Commercial is as
of and for the years ended June 30, 1997, 1996, 1995, 1994 and 1993. This
information has been derived from and should be read in conjunction with
Commercial's Consolidated Financial Statements and the Notes thereto, as well as
the information under the caption "Selected Consolidated Financial Data"
contained in Commercial's Annual Report on Form 10-K for the fiscal year ended
June 30, 1997, which is incorporated herein by reference. The following summary
consolidated interim financial data for the three months ended September 30,
1997 and 1996 has been derived from unaudited consolidated interim financial
statements which, in the opinion of management, include all adjustments
(consisting of normal recurring adjustments), considered necessary for a fair
presentation. The summary consolidated financial data for the three months ended
September 30, 1997 and 1996 should be read in conjunction with Commercial's
unaudited Consolidated Financial Statements and the Notes thereto for the three
months ended September 30, 1997 and 1996 included in Commercial's Quarterly
Report on Form 10-Q for the quarter ended September 30, 1997, which is
incorporated herein by reference. The consolidated financial data for the three
months ended September 30, 1997 is not necessarily indicative of the operating
results to be expected for the entire fiscal year. On November 17, 1997, the
Board of Directors of Commercial authorized a three-for-two stock split to be
effected in the form of a 50 percent stock dividend to stockholders of record on
November 28, 1997. Par value remained at $.01 per share. The stock dividend was
distributed on December 15, 1997. Fractional shares resulting from the stock
split were paid in cash. All per share data and stock prices for all periods
presented in this Prospectus/Proxy Statement have been adjusted on a retroactive
basis to reflect the effect of this three-for-two stock split.

                  UNAUDITED PRO FORMA COMBINED PER SHARE DATA

         The following table presents selected per share data for Commercial and
First National on a historical and pro forma combined basis as if the
Acquisition Merger had been effective as of the dates or the beginning of the
periods indicated.

         The Acquisition Merger is expected to be accounted for as a purchase,
and pro forma data is derived in accordance with such method. Such pro forma
equivalent per share amounts as to net income or loss from continuing
operations, dividends and book value are computed by multiplying the pro forma
combined amounts by an Exchange Ratio of 55.0242. Such Exchange Ratio is based
on an Aggregate Purchase Price of $27.8 million and assumes that a total of
18,044 shares of First National Common Stock are outstanding at the Acquisition
Merger Effective Time and the closing price per share of Commercial Common Stock
on January 5, 1998 of $35.125.

         Historical information for Commercial and First National is derived
from the respective consolidated financial statements incorporated by reference
herein or included elsewhere herein. The pro forma results might not be
indicative of the results that would have occurred if the Acquisition Merger had
occurred at the beginning of the periods indicated or which may be obtained in
the future. The information below should be read in conjunction with such
historical consolidated financial statements of Commercial and the combined
financial statements of First National.

         On November 17, 1997, the Board of Directors of Commercial authorized a
three-for-two stock split to be effected in the form of a 50 percent stock
dividend to stockholders of record on November 28, 1997. Par value remained at
$.01 per share. The stock dividend was distributed on December 15, 1997.
Fractional shares resulting from the stock split were paid in cash. All per
share data and stock prices for all periods presented in this Prospectus/Proxy
Statement have been adjusted on a retroactive basis to reflect the effect of
this three-for-two stock split.

                  INFORMATION CONCERNING THE SPECIAL MEETING


General

         This Prospectus/Proxy Statement is being furnished to the stockholders
of First National as part of the solicitation of proxies by its Board of
Directors from holders of the outstanding shares of First National Common Stock
for use at the Special Meeting to be held on January 30, 1998, and any
adjournments thereof. This Prospectus/Proxy Statement, and the accompanying
proxy card, are first being mailed to stockholders of First National on or about
January 9, 1998.

         The principal purpose of the Special Meeting is to consider and vote
upon the approval of the Acquisition Merger pursuant to which First National
will merge into Commercial, and the Merger Agreement among Commercial, the Bank,
First National and First United, which sets forth the terms and conditions of
the Acquisition Merger and also provides for the Bank Merger. See "The Merger --
Conversion of First National Common Stock." The Merger is subject to certain
conditions, including regulatory approval of the OTS.

In this Prospectus/Proxy Statement, the terms "Commercial" and "First National"
refer to the parent corporation only or to both the parent corporation and its
subsidiaries, depending on the context.

Solicitation, Voting and Revocability of Proxies

         The Board of Directors of First National has fixed the close of
business on January 8, 1998 as the record date (the "Record Date") for the
determination of the First National stockholders entitled to notice of and to
vote at the Special Meeting. Accordingly, only holders of record of shares of
First National Common Stock at the close of business on such date will be
entitled to vote at the Special Meeting, with each such share entitling its
owner to one vote on all matters properly presented at the Special Meeting. On
the Record Date, there were approximately 24 holders of record of the 15,317.65
shares of First National Common Stock then outstanding. The presence, in person
or by proxy, of a majority of the total number of outstanding shares of First
National Common Stock entitled to vote at the Special Meeting is necessary to
constitute a quorum at the Special Meeting. Abstentions and broker non-votes
will be treated as shares present at the Special Meeting for purposes of
determining the presence of a quorum. The affirmative vote of at least a
majority of the issued and outstanding shares of First National Common Stock is
required to approve the Acquisition Merger and the Merger Agreement. Mr. J.
Thomas Burcham, Chairman of the Board of First National has entered into a
Voting Agreement with Commercial in which Mr. Burcham agreed to vote all of the
11,168.412 shares of outstanding First National Common Stock beneficially owned
by him as of the Record Date FOR approval of the Acquisition Merger and the
Merger Agreement. See also "The Merger -- Voting Agreement."

         If the accompanying proxy card is properly executed and returned to
First National in time to be voted at the Special Meeting, the shares
represented thereby will be voted in accordance with the instructions marked
thereon. Executed but unmarked proxies will be voted for approval of the
Acquisition Merger and the Merger Agreement. Except for procedural matters
incident to the conduct of the Special Meeting, the Board of Directors of First
National does not know of any matters other than those described in the Notice
of Special Meeting that are to come before the Special Meeting. If any other
matters are properly brought before the Special Meeting, the persons named in
the First National proxy will vote the shares represented by such proxy on such
matters as determined by a majority of First National's Board of Directors.
Abstentions and broker non-votes will not be voted and therefore, with respect
to the proposal to approve the Acquisition Merger and the Merger Agreement,
abstentions and broker non-votes will have the same effect as votes against
approval of those proposals.

                                       1
<PAGE>
 
         The presence of a stockholder at the Special Meeting will not
automatically revoke such stockholder's proxy. A stockholder may, however,
revoke a proxy at any time prior to its exercise by filing a written notice of
revocation with, or by delivering a duly executed proxy bearing a later date to,
the Corporate Secretary of First National at its headquarters address or by
attending the Special Meeting and voting in person.

         The cost of soliciting proxies for the Special Meeting will be borne by
First National. In addition to use of the postal system, proxies may be
solicited personally or by telephone or telegraph by directors, officers and
employees of First National, who will not be specially compensated for such
activities.


                                  THE MERGER

         The following information with respect to the Merger, insofar as it
relates to matters contained in the Merger Agreement, including the exhibits
thereto, is qualified in its entirety by reference to the full text of such
agreement, which is attached as Annex A to this Prospectus/Proxy Statement and
is incorporated by reference herein.

General

         The Merger Agreement provides for the acquisition of First National by
Commercial, and the subsequent merger of First United into the Bank, as follows:
(i) First National will merge into Commercial, with Commercial as the surviving
corporation, pursuant to which the outstanding shares of First National's Common
Stock would be converted into shares of Commercial Common Stock as set forth
below (the Acquisition Merger); and (ii) First United will then merge into the
Bank, with the Bank as the surviving savings institution (the Bank Merger)
(collectively, the Merger). Upon the consummation of the Acquisition Merger (the
Acquisition Merger Effective Time), First National will have merged into
Commercial. Upon the consummation of the Bank Merger (the Bank Merger Effective
Time), First United will have merged into the Bank, Commercial will be the
resulting savings institution holding company, and the Bank will be the
resulting subsidiary savings institution. It is anticipated that the Bank Merger
Effective Time will occur immediately following the Acquisition Merger Effective
Time. For additional information regarding the Merger, see the Merger Agreement,
which is attached as Annex A hereto.

Background of the Merger

         Merger negotiations between the Management of First National and
Commercial commenced in June of 1997 when Mr. J. Thomas Burcham, Chairman of
First National was approached by Mr. James Laphen, President of Commercial to
determine whether First National had an interest in causing First United to be
merged with Commercial's principal subsidiary, the Bank. Because such a
transaction would have resulted in First National, rather than its stockholders,
receiving the merger consideration, Mr. Burcham advised Commercial that the
transaction as proposed would not be acceptable. A merger between First National
and Commercial Federal was not acceptable to either party because Commercial
Federal was not interested in acquiring and First National was not interested in
selling the Missouri Bank which, at that time, and until November 20, 1997, was
a subsidiary of First National.

         The financial terms and other aspects of the proposed acquisition of
First United by Commercial were of interest to First National and its principal
stockholders, so efforts commenced by the parties to structure the transaction
in such a way that First National, rather than First United would be acquired.
This would require removal of the stock of Missouri Bank & Trust Company from
First National prior to a transaction with Commercial Federal. For a period of
approximately ten weeks, the parties negotiated price and structure in
consultation with their legal and accounting advisors. After considering a
number of alternatives, the present structure was agreed upon and the Merger
Agreement was signed on September 11, 1997.


         Pursuant to the Merger Agreement, First National agreed that the stock
of the Missouri Bank would be spun off to the stockholders in a tax-free
transaction. Although such spin-off was expected to be non-taxable to the

                                       2
<PAGE>
 
stockholders, it would result in an estimated income tax liability in the amount
of $900,000 to First National as First National recognized a gain to the extent
of the excess of the fair market value of its investment in the Missouri Bank
over its cost basis.

         One of the conditions of Commercial's willingness to acquire First
National was that the stockholders of First National inject sufficient funds
prior to the Merger to satisfy its income tax obligations as well as other
indebtedness of First National. The total required injection would amount to
approximately $4.2 million. To address this concern, an Agreement Among
Stockholders was entered into among the First National stockholders. That
Agreement provides that prior to the effectiveness of the merger, First National
will sell sufficient shares of common stock to its stockholders to retire all of
its liabilities. Pursuant to that commitment, First National has obtained
subscriptions from its stockholders to purchase additional shares of First
National's Common Stock for an aggregate consideration of $3.0 million. Such
subscriptions will be paid immediately prior to the Acquisition Merger.
Therefore, the Acquisition Merger consideration per share takes into account the
issuance of such additional shares immediately prior to the Acquisition Merger.

Reasons for the Merger and Recommendations of the First National Board of
Directors

         The Board of Directors of First National believes that the terms of the
Merger Agreement are fair to, and in the best interests of, First National and
its shareholders. In addition, the Board of Directors of First National, by
unanimous vote of those present, approved the Merger Agreement and the
transaction contemplated thereby and recommends that the shareholders of First
National vote for approval and adoption of the Merger Agreement and the
transaction contemplated thereby.

         In considering the terms and conditions of the Merger Agreement, the
Board of Directors of First National considered a number of factors. It 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 Board of
                  -----------------------------------------------
         Directors of First National is of the view that, based on historical
         and anticipated trading ranges for Commercial Common Stock, the value
         of the consideration to be received by the shareholders of First
         National represents a fair multiple of First National per share book
         value and earnings. The Board of Directors of First National believes
         that the Merger provides holders of the First National Common Stock
         with the opportunity to receive a premium over the prices per share of
         First National Common Stock at which individual purchases have occurred
         in the past and will enable them to participate as Commercial
         stockholders, on a tax-deferred basis, in the expanded opportunities
         for growth and profitability made possible by the Merger. Additionally,
         the Board of Directors recognizes that the shares of Commercial Common
         Stock were listed for trading on the NYSE and provide a liquid
         investment as compared to shares of First National Common Stock. The
         Board of Directors of First National also considered that the Merger
         would qualify as a tax-free organization under the Internal Revenue
         Code of 1986, as amended (the "Code"). See " -- Federal Income Tax
         Consequences."

                  The Non-Financial Terms of the Merger. The Board of Directors
                  -------------------------------------
         of First National considered the social and economic effect on the
         employees, depositors and customers of, and other dealing with, First
         United and on the communities in which First United is located or
         operates. The Board of Directors of First National believes that the
         Merger and the anticipated merger of First United with the Bank will
         result in a combined entity that is (i) committed to serving the
         banking and other financial needs of First United's depositors,
         employees, customers and communities, (ii) capable of competing more
         effectively with larger financial institutions that have exerted
         increasing competitive pressure on First United, (iii)
         well-capitalized, and (iv) capable of enjoying significant market
         penetration in Great Bend and the central Kansas banking market. First
         National's Board of Directors then concluded that Commercial would be
         an excellent successor to First National's existing owners.

         THE FIRST NATIONAL BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE
MERGER AGREEMENT AND THE ACQUISITION MERGER BE ADOPTED AND APPROVED BY ALL
STOCKHOLDERS.

Conversion of First National Common Stock

         Exchange Ratio. Each share of First National Common Stock issued and
outstanding at the Acquisition Merger Effective Time (other than shares owned by
First National or Commercial or their subsidiaries (other than in a 401(k) plan
or in a fiduciary capacity) or Dissenting Shares)) will be converted into and
represent solely the right to receive a number of shares of Commercial Common
Stock (such number of shares referred to as the "Exchange Ratio") based upon the
Average NYSE Closing Price of Commercial Common Stock as follows: (i) if the
Average NYSE Closing Price is equal to or greater than $24.00 but equal to or
less than $28.00, then the Exchange Ratio shall be such number of shares of
Commercial Common Stock equal to the quotient (carried to four digits and
rounded down) that results by dividing the Per Share Purchase Price by the
Average NYSE Closing Price of Commercial Common Stock; (ii) if the Average NYSE
Closing Price is greater than $28.00, the Exchange Ratio shall be the quotient
that results from dividing the Per Share Purchase Price by $28.00; (iii) if the
Average NYSE Closing Price is less than $24.00, then the Exchange Ratio shall be
the quotient that results from dividing the Per Share Purchase Price by $24.00.

         Pursuant to the terms of the Merger Agreement, the Aggregate Purchase
Price is $27.8 million, subject to adjustment, both upward and downward, in
certain circumstances. On November 19, 1997, all of First National's
stockholders entered into an Agreement among Stockholders which provides for,
among other things, the sale and issuance of additional shares of First National
Common Stock, the proceeds of which will be used to satisfy First National's
liabilities as of the Acquisition Merger Effective Time. As such, First National
does not anticipate that there will be any adjustments (upward or downward) of
the Aggregate Purchase Price. It is currently anticipated that a maximum of
18,044 shares of First National Common Stock will be outstanding at the
Acquisition Merger Effective Time. Based on an Aggregate Purchase Price of $27.8
million, a total of 18,044 shares of First National Common Stock outstanding at
the Acquisition Merger Effective Time and the closing price per share of
Commercial Common Stock on the NYSE on January 5, 1998, of $35.125, each share
of First National Common Stock would be exchanged for 55.0242 shares of
Commercial Common Stock. The actual number of shares to be received for each
share of First National Common Stock at the Acquisition Merger Effective Time
will vary from this amount should any of these assumptions change. In all cases,
cash will be paid in lieu of fractional shares.

         The Merger Agreement provides that First National may elect to
terminate the Merger Agreement during the two business day period commencing
immediately after the end of the Determination Period if both of the following
conditions are met: (i) the Average NYSE Closing Price is less than $22.10; and
(ii) the quotient obtained by dividing the Average NYSE Closing Price by the
"Starting Price" (as defined below) is less than the "Index Trigger" (as defined
below). If First National elects to exercise its right to terminate the Merger
Agreement, it must give written notice of its intention no later than the end of
the aforementioned two day period. During the two business day period
immediately after Commercial's receipt of such notice, Commercial shall have the
right to adust the Exchange Ratio to equal the lesser of (i) the quotient
obtained by dividing (A) the product of $22.10 and the Exchange Ratio (as then
in effect) by (B) the Average NYSE Closing Price and (ii) the quotient obtained
by dividing the product of the Index Trigger and the Exchange Ratio (as then in
effect) and the Starting Price by (B) the Average NYSE Closing Price. If
Commercial so elects, it must give notice to First National and no termination
of the Merger Agreement will be deemed to have occurred.

         For purposes of this provision, the term "Index Trigger" is defined as
the quotient obtained by dividing the Index Price (as defined below) on the last
day of the Determination Period by the Index Price on September 11, 1997 (the
date immediately preceding the date of public announcement of the Merger
Agreement) and subtracting .10 from the quotient. "Starting Price" is defined as
$26.00. "Index Price" is defined as the weighted average of the closing prices
on the specified date of the common stocks of certain financial institutions
specified in the Merger Agreement (the "Index Group").

                                       4
<PAGE>
 
         No Fractional Shares. No fractional shares of Commercial Common Stock
will be issued in the Merger. Instead, cash will be paid in lieu of any
fractional share interests of Commercial Common Stock resulting from the Merger.
No dividend or distribution with respect to Commercial Common Stock will be
payable on or with respect to any fractional share interests, and no fractional
share interest will entitle the owner thereof to vote or to any other rights of
a stockholder of Commercial. The applicable cash value of each fractional share
interest will be equal to the product of such fraction multiplied by the Average
NYSE Closing Price for shares of Commercial Common Stock.

         Exchange of First National Stock Certificates. Prior to the Acquisition
Merger Effective Time, Commercial will appoint an exchange agent (the "Exchange
Agent") to effect the exchange of stock certificates in connection with the
Merger. As soon as practicable after the Acquisition Merger Effective Time but
not later than 10 business days thereafter, the Exchange Agent will send a
notice and transmittal form to each First National stockholder of record at the
Acquisition Merger Effective Time whose First National Common Stock has been
converted into Commercial Common Stock, advising such stockholder of the
effectiveness of the Acquisition Merger and the procedure for surrendering to
the Exchange Agent outstanding certificates formerly evidencing First National
Common Stock in exchange for new certificates of Commercial Common Stock and for
cash in lieu of any fractional interest. Promptly following receipt of such
notice and transmittal form, holders of First National Common Stock certificates
should surrender their certificates in accordance with the specified procedures.
Upon surrender, each First National Common Stock certificate will be canceled.

         Until surrendered, certificates that, prior to the Acquisition Merger
Effective Time, represented outstanding shares of First National Common Stock
will be deemed for all corporate purposes to evidence the right to receive cash
in lieu of any fractional interest and the ownership of the number of whole
shares of Commercial Common Stock into which such shares of First National
Common Stock have been converted. Until such certificates are so surrendered, no
dividend or distribution payable to holders of Commercial Common Stock as of any
record date subsequent to the Acquisition Merger Effective Time will be paid to
the holders of such certificates. However, upon surrender of such certificates,
there will be paid to the record holder of the certificates of Commercial Common
Stock issued in exchange therefor the amount of dividends or distribution that
theretofore have become payable with respect to such shares of Commercial Common
Stock along with the amount of cash, if any, payable to the holder in lieu of
fractional shares. No interest will be payable with respect to such dividends or
distribution or cash paid in lieu of fractional shares.

         If any certificate for shares of Commercial Common Stock is to be
issued in a name other than the name in which the surrendered certificate is
registered, it will be a condition of issuance that the certificate so
surrendered is properly endorsed and otherwise in proper form for transfer and
that the person requesting the transfer of such certificate either pay to the
Exchange Agent any transfer or other taxes required by reason of the issuance of
the certificate in a name other than the registered holder of the certificate
surrendered, or establish to the satisfaction of the Exchange Agent that such
tax has been paid or is not payable.

         Holders of First National Common Stock should NOT surrender their
certificates until they receive written instructions from the Exchange Agent.

         Any shares of First National Common Stock owned or held by Commercial
or any of its subsidiaries (other than in a fiduciary capacity) or by First
National or any of its subsidiaries (other than in a fiduciary capacity) at the
Acquisition Merger Effective Time will cease to exist, and the certificates for
such shares will be canceled.

Dissenters' Rights of Appraisal

         Under Section 17-6711 of the Kansas General Corporation Code ("KGCC"),
a copy of which is attached to this Prospectus/Proxy Statement as Annex B, any
holder of record or beneficial holder of First National Common Stock has the
right to dissent from the Merger and demand payment of the fair value of his or
her shares in cash. Any stockholder who wishes to assert dissenters' rights must
file a written notice of his or her intent to demand payment with First
National, Attention: J. Thomas Burcham, Chief Executive Officer, 1044 Main
Street, Kansas City, Missouri 64196, 

                                       5
<PAGE>
 
before the vote on the Merger Agreement is taken at the Special Meeting and must
refrain from voting in favor of the Merger Agreement. A PROXY OR VOTE AGAINST
THE MERGER AGREEMENT WILL NOT, BY ITSELF, BE REGARDED AS A WRITTEN NOTICE OF
INTENT TO DEMAND PAYMENT FOR PURPOSES OF ASSERTING DISSENTERS' RIGHTS.

         A beneficial owner of First National common stock may assert
dissenters' rights of appraisal upon (i) filing a written objection with the
corporation before the vote on the Merger was taken and (ii) either abstaining
or voting against the merger. A stockholder has properly perfected his or her
rights to an appraisal, provided that the appropriate notice is given and vote
at the stockholder meeting is cast.

         Upon the Merger becoming effective, the surviving corporation,
Commercial, must send written notice to each of dissenting stockholders of the
merged corporation, First National, who properly perfected their appraisal
rights. Such notice must be sent by Commercial within ten (10) days after the
Effective Date of the merger.

         If the dissenting stockholder is dissatisfied with the payment or
offer, such dissenting stockholder, within twenty (20) days after the date
notice was mailed by Commercial, must demand in writing from Commercial, the
payment of the value of the stockholder's stock. Commercial will then have
thirty (30) days after the expiration of the period of the twenty (20) day
period, in which to pay the dissenting stockholder the value of the
stockholder's stock on the effective date of the merger, exclusive of any
element of value arising from the expectation or accomplishment of the merger.

         If during the thirty (30) day period Commercial and the dissenting
stockholder fail to agree upon the value of such stock, then either the
dissenting stockholder(s) or Commercial may demand a determination of value of
the stock by an appraiser or appraisers to be appointed by the district court,
by filing a petition with the court within four (4) months after the expiration
of the thirty (30) day period.

         The petition for a determination of value by an appraiser or appraisers
may be filed by either the dissenting stockholder or Commercial. A dissenting
stockholder filing the petition with the district court is required to serve a
copy of the petition upon the surviving corporation, Commercial. Then upon
Commercial's receipt of the petition, Commercial must then submit a duly
verified list containing all the names and addresses of all dissenting
stockholders unable to reach an agreement with the surviving corporation, with
the clerk of the court within ten (10) days after receiving such service. If the
petition is filed by Commercial, then Commercial will be required, at the time
of submitting the petition, to also provide the duly verified list of dissenting
stockholders with the clerk of the court. The clerk of the court will notify all
dissenting stockholders appearing on the list by registered or certified mail,
and the clerk will also cause notice to be published one week prior to the
hearing in a newspaper of general circulation in the county where the court is
located.

         Upon filing the petition for a determination of value by the court, all
of the dissenting stockholders holding certificated shares must submit those
certificates to the clerk of the court pending the appraisal proceedings. In
addition, the shares of Commercial common stock which the dissenting First
National stockholder would have been entitled to in the conversion had they
assented to the merger will have the status of authorized and unissued shares of
Commercial.

         The district court will then hold a hearing (i) to determine the
stockholders that have properly complied with all provisions of this section and
are entitled to valuation of and payment for their shares, (ii) to appoint an
appraiser or appraisers to determine such value.

         The court-appointed appraiser is charged with the duty of valuing, and
making a determination of the value of the shares of the merged corporation. In
order to make an accurate determination of the value of the shares, the
appraiser has the authority to examine any of the books and records of the
Commercial and First National. The appraiser or appraisers will also afford a
reasonable opportunity to the parties interested to submit pertinent evidence on
the value 

                                       6
<PAGE>
 
of the shares. Upon making a determination of value, the appraiser must file a
report respecting such value in the office of the clerk of the court, and notice
of filing of such report will be given by the clerk to the parties in interest.

         The court by decree will determine, based upon legal and factual
argument of each of the parties and the appraisal report, the value of the
stock. The court will then direct the payment of such value, together with
interest, if any, to the dissenting stockholders entitled to payment by the
surviving corporation, Commercial. Commercial, upon payment of the value to the
dissenting stockholders, will receive the certificates held by the clerk of the
court.

         The decree of the court may be enforced as other judgements of the
district court may be enforced, whether Commercial is a corporation of the State
of Kansas or of any other state.

         Any First National stockholder who asserts his or her dissenters'
rights will not be entitled to vote such stock for any purpose or be entitled to
the payment of dividends or other distribution on the stock, except those
dividends or distributions payable to stockholders of a record date prior to the
Effective Date of the merger, unless an appointment of an appraiser has not been
provided, the proceeding is dismissed as to such stockholders, or such
stockholders with written approval of the corporation, will deliver to the
corporation a written withdrawal of the stockholder's objections to and
acceptance of the merger.

Voting Agreement

         As a condition to Commercial entering into the Merger Agreement, Mr. J.
Thomas Burcham, Chairman of the Board of First National has entered into a
Voting Agreement with Commercial. The Voting Agreement provides that Mr. Burcham
will vote all of his shares of First National Common Stock beneficially owned in
favor of the Merger Agreement and the Acquisition Merger, waiving all rights he
may have under Section 17-6712 of the Kansas General Corporation Code ("KGCC")
in connection with the Merger. The Voting Agreement prohibits Mr. Burcham from
voting his shares in favor of any other merger or sale of all or substantially
all of the assets of First National to any person other than Commercial and its
affiliates. The Voting Agreement prohibits the sale, assignment, or transfer of
shares subject to the Voting Agreement. The Voting Agreement provides that it
will terminate upon the earlier of (i) the Acquisition Merger Effective Time,
(ii) the termination of the Merger Agreement or (iii) the abandonment of the
Merger by mutual agreement of Commercial and First National.

The Bank Merger

         Following the Acquisition Merger, First United will merge into the
Bank, as a result of which the Bank will be the surviving savings institution.
The Bank Merger will be undertaken subject to and upon the terms and conditions
contained in the Merger Agreement and in the Plan of Merger between First United
and the Bank dated September 11, 1997. At the Bank Merger Effective Time, the
shares of First United common stock issued and outstanding immediately prior
thereto will be canceled and the shares of capital stock of the Bank outstanding
immediately prior thereto will constitute the only outstanding shares of capital
stock of the Bank following consummation of the Bank Merger, the charter and
bylaws of the Bank in effect immediately before the Bank Merger will be the
charter and bylaws of the Bank immediately after the Bank Merger, the current
home office of the Bank will continue to be the home office of the Bank, and the
former home office of First United and all branch offices of the Bank and former
branch offices of First United will be branch offices of the Bank. Following the
Bank Merger, the Bank will continue to operate under the name "Commercial
Federal Bank, a Federal Savings Bank." For additional information, see " --
Management after the Merger," " -- Employee Benefit Plans after the Merger" and
" -- Interests of Certain Persons in the Merger."

         The obligations of the parties to consummate the Bank Merger are
subject to the receipt of OTS approval of the Bank Merger.

National and Commercial, except that after approval of the Merger Agreement by
First National's stockholders, no such amendment without further approval by
First National's stockholders may change the amount or form of the consideration

Acquisition Merger Effective Time, whether before or after approval by First
National stockholders; (i) by mutual consent of the parties evidenced by their
written agreement; (ii) at the election of either party, if the closing of the
Merger shall not have occurred on or before June 30, 1998 or such later date as

perform an obligation has been the cause of, or has resulted in, the failure of
the closing to occur on or before such date; (iii) by Commercial upon delivery
of written notice of termination to First National if any event occurs which
renders impossible the satisfaction 

                                       13

right to terminate under this provision shall not be available to First National
where First National's failure to perform an obligation under the Merger
Agreement has been the cause of, or has resulted in, the failure of the closing
to occur on or before such date; and (v) by First National at any time during
the two business days commencing on the business day immediately following the
end of the Determination Period, if both of the following conditions are met (1)
the Average NYSE Closing Price of Commercial Common Stock is less than $22.10
and (2) the quotient obtained by dividing the Average NYSE Closing Price by the
Starting Price ($26.00) is less than the Index Trigger (the quotient obtained by
dividing the weighted average of closing prices of the common stocks of
companies comprising the Index Group (the "Index Group") on the last day of the
Determination Period by the Index Price on the last trading day immediately
preceding September 11, 1997 (or if no trades of Commercial Common Stock
occurred on that day, the date most immediately preceding September 11, 1997 on
which a trade occurred) and subtracting 0.10); subject to the following: (a)
written notice to Commercial no later than the end of the two business day
period; (b) Commercial shall have the option to inform First National in writing
during the two day period following the receipt of First National's written
notice to increase the consideration to be received by the holders of First
National Common Stock, by adjusting the Exchange Ratio to equal the lesser of
(I) the quotient obtained by (A) dividing the product of $22.10 and the Exchange
Ratio (as then in effect) by (B) the Average NYSE Closing Price and (II) the
quotient obtained by dividing (A) the product of the Index Trigger and the
Exchange Ratio (as then in effect) and $26.00 by (B) the Average NYSE Closing
Price, whereupon no termination shall have occurred and the Merger Agreement
remains in effect with its terms (except as the Exchange Ratio shall have been
modified).

         In the event the Merger Agreement is terminated, the Merger Agreement
becomes void and will have no further effect with the exception that the
provisions regarding (i) brokers and finders fees; (ii) publicity regarding the
Merger Agreement; (iii) payment of expenses; and (iv) confidentiality will
survive any such termination and abandonment. In addition, in the event of a
termination due to the inability of one of the parties to satisfy one or more of
the conditions to its obligation to effect the Merger, the termination of the
Merger Agreement will not relieve the breaching party from liability for an
uncured, intentional and willful breach of a representation, warranty, covenant
or agreement giving rise to such termination. The representations, warranties
and agreements of the parties set forth in the Merger Agreement shall survive
the Acquisition Merger Effective Time, and shall not be terminated and
extinguished at the Acquisition Merger Effective Time.

Termination Fee

         The Merger Agreement further provides that in the event the Merger
Agreement is terminated by either Commercial or First National in accordance
with the Merger Agreement and, prior to such termination, a "Termination Event"
(as defined below) has occurred, then First National will pay on demand One
Million Dollars ($1,000,000) (the "Termination Fee") and an additional amount
equal to the reasonable expenses incurred by Commercial relating to the Merger
Agreement and the transactions contemplated thereby. A "Termination Event" is
defined in the Merger Agreement to mean any of the following: (i) First National
or any First National Subsidiary or any stockholder of First National shall have
entered into an agreement to engage in an "Acquisition Transaction" (as defined
below) with any person (the term "person" for purposes of the Merger Agreement
having the meaning assigned thereto in Section 3(a)(9) and 13(d)(3) of the
Exchange Act, and the rules and regulations thereunder) other than Commercial or
any affiliate of Commercial (the term "affiliate" for purposes of the Merger
Agreement having the meaning assigned thereto in Rule 405 under the Securities
Act of 1933); (ii) the stockholders of First National shall not have approved
the Acquisition Merger at the meeting held for that purpose or any adjournment
thereof (or through solicitation of consents) or such meeting shall not have
been held or shall have been canceled prior to termination of the Merger
Agreement (unless consents shall have been solicited and received in lieu of
such meeting) or no consents solicited or the Board of Directors of First
National shall have recommended that the stockholders of First National approve
or accept any Acquisition Transaction with any person other than Commercial or
any affiliate of Commercial; and (iii) after a proposal is made by any person
other than Commercial or any affiliate of Commercial to First National or any of
its stockholders to engage in an Acquisition Transaction. First National or any
First National subsidiary shall have knowingly 

                                       14
<PAGE>
 
and intentionally breached any representation, warranty, agreement, covenant or
obligation contained in the Merger Agreement, such breach would entitle
Commercial to terminate the Merger Agreement and such breach is not cured within
30 day thereafter.

         For purposes of the Merger Agreement, the term "Acquisition
Transaction" is defined to mean: (i) a merger or consolidation or any similar
transaction involving First National or any subsidiary of First National; (ii) a
purchase, lease or other acquisition of all or substantially all of the assets
of First National or any First National subsidiary; or (iii) a purchase or other
acquisition (including by way of merger, consolidation, share exchange or
otherwise) of securities representing 10% or more of the equity securities of
First National or any First National subsidiary.

Required Regulatory Approvals

         The Merger is subject to the approval of the OTS. Commercial has filed
an application with the OTS for approval of the Merger. As of the date of this
Prospectus/Proxy Statement, the approval of the OTS has not been received. There
can be no assurance as to the timing of such approval, if given, or as to the
conditions, if any, on which approval will be given. In addition, the approval,
if and when granted, may contain conditions which Commercial may find unduly
burdensome. It is a condition to Commercial and the Bank's obligations to effect
the Merger that such approval does not contain any conditions which Commercial
and the Bank reasonably and in good faith determine to be unduly burdensome upon
the conduct of the business of Commercial or the Bank and, in the sole
discretion of Commercial, substantially diminish the benefits expected to be
received by Commercial from the transactions contemplated by the Merger
Agreement. When such approval is received, material changes to the Merger
Agreement, material conditions, or other changes of a material nature may be
imposed by regulatory authorities in connection therewith which could require a
resolicitation of First National's stockholders for approval. Following OTS
approval of the Merger, the U.S. Department of Justice may review the Merger and
raise objections on antitrust grounds, though objections on such grounds are not
expected. If the required regulatory approvals are not obtained, the Merger
Agreement will be terminated, and the Merger will not occur.

Expenses

         Pursuant to the Merger Agreement, each of the parties shall bear and
pay all costs and expenses incurred by it or on its behalf in connection with
the transactions contemplated thereunder.

Closing; Merger Effective Times

         As promptly as practicable following the approval of the Merger
Agreement by First National's stockholders and the satisfaction or waiver of all
conditions of the Merger Agreement, the closing shall take place at which the
parties thereto will exchange documents required by the Merger Agreement.
Immediately following the Closing, and on the same day if practicable, the
Acquisition Merger shall become effective at the time and date the Nebraska
articles of merger are filed with the appropriate authorities in Nebraska and
the Kansas certificate of merger is filed with the appropriate authorities in
Kansas. Following the Acquisition Merger, the Bank Merger shall become effective
at the time the articles of combination for such merger are endorsed by the OTS.

Employee Benefit Plans after the Merger

         To the extent permitted by applicable law, the employees of First
National who become employees of Commercial or the Bank shall be eligible to
participate in all benefit plans sponsored by Commercial or the Bank to the same
extent as other similarly situated employees of Commercial or the Bank, with
full credit for prior service with First National or its subsidiaries for
purposes of vesting, eligibility for participation and co-payments and
deductibles. Commercial shall honor accrued vacation leave for the employees of
First National and its subsidiaries following the Acquisition Merger Effective
Time.

                                       15

Interests of Certain Persons in the Merger

         Advisory Board. Commercial has also agreed to offer compensated
advisory director status to all members of the boards of directors of First
United, except for J. Thomas Burcham and Grant Burcham.

         Consulting Agreement. In addition, Commercial has entered into a
consulting agreement with Mr. J. Thomas Burcham, Chairman of the Board of First
National, commencing at the Acquisition Merger Effective Time and continuing for
a period of three years. Under this Agreement, Mr. Burcham will be required to
provide assistance in the post-Merger transition period and to render
consulting, advisory and other services regarding business development and
general banking matters in the communities served by First United. Under the
consulting agreement, Mr. Burcham will receive approximately $125,000 per year.

         Indemnification; Director and Officer Insurance. Pursuant to the Merger
Agreement, Commercial has agreed that for a period of three years following the
Acquisition Merger Effective Time, the Merger will not affect or diminish any of
First National's duties and obligations of indemnification existing as of the
Acquisition Merger Effective Time in favor of employees, agents, directors or
officers of First National or any of its subsidiaries arising by virtue of First
National's Articles of Incorporation or Bylaws in the form in effect at the date
of the Merger Agreement or arising by operation of law. Commercial will cause
the persons serving as officers and directors of First National immediately
prior to the Acquisition Merger Effective Time to be covered for a period of 18
months from the Acquisition Merger Effective Time by the directors' and
officers' liability insurance policy maintained by First National (provided that
Commercial may substitute therefor policies of at least the same coverage and
amounts containing terms and conditions which are not materially less
advantageous than such policy) with respect to acts or omissions occurring prior
to the Acquisition Merger Effective Time which were committed by such officers
and directors in their capacity as such; however, in no event will Commercial be
required to expend more than 150% of the amount currently expended by First
National on an annual basis to maintain or procure insurance coverage for such
18 month period pursuant to the Merger Agreement.

Federal Income Tax Consequences

         Commercial and First National will rely upon an opinion of Deloitte &
Touche LLP, tax advisor to Commercial, to the following effect:

         .        the Acquisition Merger should qualify as a reorganization
                  within the meaning of Section 368(a)(1)(A) of the Code. First
                  National and Commercial should each be a "party to a
                  reorganization" within the meaning of Section 368(b) of the
                  Code.

         .        First National should recognize no gain or loss on the
                  transfer of its assets to Commercial in exchange for the
                  Commercial Common Stock, cash, if any, and the assumption of
                  its liabilities by Commercial, by reason of the application of
                  Sections 361(a), 361(b) and 357(a) of the Code.

         .        no gain or loss should be recognized by First National upon
                  the distribution of the Commercial Common Stock to the First
                  National stockholders, by reason of the application of Section
                  361(c)(1) of the Code.

         .        no gain or loss should be recognized by Commercial on the
                  receipt of First National's assets in exchange for Commercial
                  Common Stock, and the assumption by Commercial of First
                  National's liabilities, by reason of the application of
                  Section 1032(a) of the Code.

         .        the basis of the assets of First National in the hands of
                  Commercial should be the same as the basis of such assets in
                  the hands of First National immediately prior to the Merger,
                  by reason of the application of Section 362(b) of the Code.

                                       16
<PAGE>
 
         .        the holding period of the property acquired by Commercial from
                  First National should include the holding period of such
                  property in the hands of First National immediately prior to
                  the Merger, by reason of the application of Section 1223(2) of
                  the Code.

         .        no gain or loss should be recognized by the former First
                  National stockholders (including fractional share interests
                  which they might otherwise be entitled to receive), by reason
                  of the application of Section 354(a) of the Code.

         .        the basis of the Commercial Common Stock (including fractional
                  share interests a First National stockholder would otherwise
                  be entitled to receive) to be received by a First National
                  stockholder who exchanges First National Common Stock for
                  Commercial Common Stock should be the same as the basis of the
                  First National Common Stock surrendered in the exchange by
                  reason of Section 358(a)(i) of the Code.

         .        the holding period of the Commercial Common Stock (including
                  fractional share interests that they would otherwise be
                  entitled to receive) to be received by First National
                  stockholders should, in each instance, include the holding
                  period of the First National shares surrendered in the
                  exchange, provided First National stock was held as a capital
                  asset on the date of the exchange, by reason of the
                  application of Code Section 1223(1).

         .        Commercial as the survivor should succeed to and take into
                  account as of the close of the day of the distribution or
                  transfer the items of First National described in Code Section
                  381(c), subject to the conditions and limitations specified in
                  Code Sections 381(b) and 381(c), by reason of the application
                  of Code Section 381(a)(2).

         .        as provided in Code Section 381(c)(2) and Regulation Section
                  1.381(c)(2)-1, Commercial as the survivor should succeed to
                  and take into account the earnings and profits, or deficit in
                  earnings and profits, of First National as of the date or
                  dates of transfer. Any deficit in earnings and profits of
                  either Commercial or First National should be used only to
                  offset earnings and profits accumulated after the date or
                  dates of transfer.

         .        cash received by a stockholder of First National otherwise
                  entitled to receive a fractional share of Commercial Common
                  Stock in exchange for his First National stock should be
                  treated as if the fractional shares were distributed as part
                  of the exchange and then were redeemed by Commercial. These
                  cash payments should be treated as having been received as
                  distributions in full payment in exchange for the stock
                  redeemed as provided in Code Section 302(a). This receipt of
                  cash should result in gain or loss measured by the difference
                  between the basis of such fractional share interest and the
                  cash received. Such gain or loss should be capital gain or
                  loss to the former First National stockholder, provided the
                  First National stock was a capital asset in such former
                  stockholder's hands and as such, will be subject to the
                  provisions and limitations of Subchapter P of Chapter 1 (Rev.
                  Rul. 66-365 and Rev. Rul. 77-41).

          .       where cash is received by a dissenting stockholder of First
                  National, such cash should be treated as received by the
                  dissenting stockholder as a distribution in redemption of his
                  stock, subject to the provisions and limitations of Section
                  302 of the Code.

The opinion of Deloitte & Touche LLP has no binding effect on the IRS. The
opinion of Deloitte & Touche LLP is filed with the Commission as an exhibit to
Commercial's registration statement on Form S-4 of which this Prospectus/Proxy
Statement is a part. See " -- Additional Information."

         Cash payments made to the holders of First National Common Stock upon
the exchange thereof in connection with the Acquisition Merger (other than
certain exempt entities and persons) will be subject to a 31.0% backup
withholding tax under federal income tax law unless certain requirements are
met. Generally, Commercial will be 

                                       17
<PAGE>
 
required to deduct and withhold the tax if (i) the stockholder fails to furnish
a taxpayer identification number ("TIN") or fails to certify under penalty of
perjury that such TIN is correct, (ii) the IRS notifies Commercial that the TIN
furnished by the stockholder is incorrect, (iii) the IRS notifies Commercial
that the stockholder has failed to report interest, dividends or original issue
discount in the past, or (iv) there has been a failure by the stockholder to
certify under penalty of perjury that such stockholder is not subject to the
31.0% backup withholding tax. Any amounts withheld in collection of the 31.0%
backup withholding tax will reduce the federal income tax liability of the
stockholders from whom such tax was withheld. The TIN of an individual
stockholder is that stockholder's Social Security number.

         THE FOREGOING CONSTITUTES ONLY A GENERAL DESCRIPTION OF THE FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER, WITHOUT CONSIDERATION OF THE PARTICULAR
FACTS AND CIRCUMSTANCES OF EACH FIRST NATIONAL'S STOCKHOLDER'S SITUATION. EACH
FIRST NATIONAL STOCKHOLDER IS ENCOURAGED TO CONSULT HIS OR HER OWN TAX AND
FINANCIAL ADVISORS AS TO PARTICULAR FACTS AND CIRCUMSTANCES WHICH MAY BE UNIQUE
TO SUCH STOCKHOLDER AND NOT COMMON TO STOCKHOLDERS AS A WHOLE AND ALSO AS TO ANY
ESTATE, GIFT, STATE, LOCAL OR FOREIGN TAX CONSEQUENCES ARISING OUT OF THE MERGER
AND/OR ANY SALE THEREAFTER OF COMMERCIAL COMMON STOCK RECEIVED IN THE MERGER.

Accounting Treatment

         The Merger will be accounted for under the purchase method of
accounting in accordance with generally accepted accounting principles,
resulting in adjustments to the carrying value of First National's assets and
liabilities to reflect their respective fair values at the date of the
Acquisition Merger.

Resale of Commercial Common Stock; Restrictions on Transfer

         The shares of Commercial Common Stock to be issued in the Acquisition
Merger will be registered under the Securities Act and will be freely
transferable under the Securities Act, except for shares issued to any
stockholder who may be deemed to be an "affiliate" of First National or
Commercial for purposes of Rule 145 under the Securities Act (generally,
individuals or entities that control, are controlled by or are under common
control with First National or Commercial). Affiliates may not sell their shares
of Commercial Common Stock acquired in connection with the Acquisition Merger
except pursuant to an effective registration statement under the Securities Act
covering such shares or in compliance with Rule 145 or another applicable
exemption from the registration requirements of the Securities Act.

         First National has agreed in the Merger Agreement to use its best
efforts to cause each director, executive officer and other person who is an
affiliate (for purposes of Rule 145) of First National to deliver to Commercial
a written agreement intended to ensure compliance with the Securities Act.

New York Stock Exchange Listing

         Commercial Common Stock is traded on the NYSE under the symbol "CFB".
It is expected that Commercial Common Stock will continue to be quoted on the
NYSE under the symbol "CFB" following the Merger.

Vote Required

         The affirmative vote of at least a majority of the outstanding First
National Common Stock is required for First National's stockholders to approve
the Merger Agreement and the Acquisition Merger. Each share of First National
Common Stock outstanding at the close of business on the record date for the
Special Meeting, January 8, 1998, is entitled to one vote on each matter to be
considered at such meeting. Mr. J. Thomas Burcham, Chairman of the Board of
First National has entered into a Voting Agreement with Commercial in which Mr.
Burcham agreed to vote all of the 11,168.412 shares of outstanding First
National Common Stock beneficially owned by him as of the Record Date FOR
approval of the Acquisition Merger and the Merger Agreement.

                      COMMERCIAL FEDERAL CORPORATION AND
                COMMERCIAL FEDERAL BANK, A FEDERAL SAVINGS BANK

         Commercial is a unitary non-diversified savings and loan holding
company whose primary asset is the Bank, which is one of the largest depository
institutions in the Midwest. At September 30, 1997, Commercial had total assets
of $7.2 billion and total stockholders' equity of $444.3 million. Based upon
total assets at that date, Commercial was the 13th largest publicly held thrift
holding company in the United States. Commercial is a consumer-oriented
financial institution that emphasizes single-family residential and construction
real estate lending, consumer lending, commercial real estate lending, retail
deposit activities, including demand deposit accounts, and mortgage banking. At
November 30, 1997, Commercial operated 34 branch offices in Nebraska, 21 branch
offices in greater metropolitan Denver, Colorado, 19 branch offices in Oklahoma,
27 branch offices in Kansas and seven branch offices in Iowa. Throughout its 110
year history, Commercial has emphasized customer service. To serve its
customers, Commercial conducts loan origination activities through its 108
branch office network, loan offices of its wholly-owned mortgage banking
subsidiary and a nationwide correspondent network of mortgage loan originators.
Commercial also provides insurance and securities brokerage and other retail
financial services.

         Commercial's strategy for growth emphasizes both internal and external
growth. Operations focus on increasing deposits, including demand accounts,
making loans (primarily single-family mortgage and consumer loans), community
banking, and providing customers with a full array of financial products and a
high level of customer service. As part of its long-term strategic plan,
Commercial intends to expand its operations within its market areas either
through direct marketing efforts aimed at increasing market share, branch
expansions, or opening additional branches. Commercial's retail strategy will
continue to be centered on attracting new customers and selling both new and
existing customers multiple products and services. Additionally, Commercial will
continue to build and leverage an infrastructure designed to increase fee and
other income.

         Complementing its strategy of internal growth, Commercial continues to
grow its present five-state franchise through an ongoing program of selective
acquisitions of other financial institutions.

         Pending Acquisitions. In addition to the Merger, Commercial has entered
into definitive agreements to acquire two other financial institution holding
companies: Liberty Financial Corporation, a commercial bank and thrift holding
company; and Mid Continent Bancshares, Inc. a savings and loan holding company.
Together with First National, these three pending acquisitions will add 59
branches to Commercial's existing network and approximately $1.2 billion in
total assets, approximately $924.0 million in deposits and approximately $1.3
billion in loans serviced for others. Liberty Financial Corporation,
headquartered in West Des Moines, Iowa, operates seven bank subsidiaries and one
thrift subsidiary with 36 branch locations in Iowa and six branch locations in
the Tucson, Arizona metropolitan area. Mid Continent Bancshares, Inc.
headquartered in El Dorado, Kansas, operates ten branch offices in Kansas.
Future acquisition candidates will be selected based on the extent to which the
candidates can enhance Commercial's retail presence in new or underserved
markets and complement Commercial's existing retail network.

         On December 15, 1997, Commercial entered into a definitive agreement to
acquire Perpetual Midwest Financial, Inc. ("Perpetual"), the holding company of
Perpetual Savings Bank, FSB ("Perpetual Savings"), headquartered in Cedar
Rapids, Iowa. In this transaction the Company will acquire through a tax-free
exchange all 1,872,925 shares of Perpetual's common stock. Perpetual
shareholders will receive .8636 shares of Commercial Common Stock for each
outstanding share of Perpetual common stock. Following the merger of Perpetual
into Commercial, Perpetual Savings will be merged into the Bank. Perpetual
Savings currently operates four branch locations in Cedar Rapids, Iowa and one
branch in Iowa City, Iowa. At September 30, 1997, Perpetual had assets of
approximately $401.7 million, deposits of approximately $310.1 million and
stockholders' equity of approximately $34.2 million. The pending acquisition is
subject to regulatory approvals, approval by Perpetual's shareholders and other
conditions. It is expected to be completed late in the second quarter of 1998.

         Recent Events. On November 18, 1997, Commercial announced at its 1997
Annual Meeting that stockholders had approved proposals to amend Commercial's
Articles of Incorporation to (i) increase the number of 

                                       19
<PAGE>
 
authorized shares of Commercial Common Stock from 25,000,000 shares to
50,000,000 shares, and (ii) establish a variable range for the number of members
of the Board of Directors of from nine to 12 members.

         In addition, Commercial announced that its Board of Directors had
authorized a three-for-two stock split to be effected in the form of a 50
percent stock dividend. Par value remained at $.01 per share. Fractional shares
were paid in cash. The Board also declared a quarterly cash dividend of $.055
per share of Commercial Common Stock which represents an increase of 17.9% from
the September 30, 1997 quarter when Commercial paid a cash dividend of $.0467
per share, after adjusting for the three-for-two stock split. The stock dividend
was distributed on December 15, 1997 to stockholders of record as of November
28, 1997. The cash dividend for the quarter ended December 31, 1997, payable to
stockholders of record as of December 31, 1997, will be paid on January 14,
1998. All per share data and stock prices presented in this Prospectus/Proxy
Statement have been adjusted on a retroactive basis to reflect the effect of
this three-for-two stock split.

         Commercial's principal executive offices are located at 2120 South 72nd
Street, Omaha, Nebraska 68124, and its telephone number is (402) 554-9200.

         The gross interest income on non-accrual loans that would have been
recorded during the year ended December 31, 1996, if the loans had been current
in accordance with their original terms and had been outstanding throughout the
year or since origination if held for part of the year, amounts to $60,000.

         There are approximately $1.4 million of loans classified current (and
which are performing) about which there are doubts as to the ability of the
borrower to comply with the loan repayment terms in the future. Of this amount,
management believes that approximately $1.4 million of such loans have
sufficient collateral to cover the debt in the event of liquidation. These loans
have been considered by First United in establishing the allowance for loan
losses.

         At December 31, 1996, First United had no foreign loans outstanding and
no loan concentrations, except for those indicated in the first table under
"--Loan Composition," exceeding 10% of total loans.

</TABLE> 

         The amount charged to operations and the related balance in the
allowance for loan losses is based upon periodic evaluations of the loan
portfolio by management. These evaluations consider several factors including,
but not limited to, general economic conditions, loan portfolio composition,
prior loan loss experience, classification of loans, and management's estimation
of future potential losses.

         The allowance for loan losses should not be interpreted as an
indication that charge-offs will occur in these amounts or proportions, or that
the allocation indicates future charge-off trends. Furthermore, the portion
allocated to each category is not the total amount available for future losses
that might occur within such categories.

         The following table illustrates the allocation of the allowance for
loan losses for each category of loan. The allocation of the allowance to each
category is not necessarily indicative of future loss in any particular category
and does not restrict the use of the allowance to absorb losses in other
categories.

Comparison of Results of Operations for the Nine Months Ended September 30, 1997
and 1996

    Net income for the nine months ended September 30, 1997 was $1.4 million,
representing a 30% increase over net income of $1.1 million for the first nine
months of 1996. Net income per share was $91.72 in the 1997 period compared to
$70.61 per share in the comparable period in 1996. For 1997 and 1996, the return
on average assets was 1.27% and 1.07%, respectively. Return on average equity
was 24.8% in 1997 compared to 23.8% in 1996.

    The increase in net income for the first three quarters of 1997 was due to
an increase in net interest income. Net interest income on a tax equivalent
basis increased $190,000 or 5.3%, primarily as a result of an increase in
average earning assets associated with an increase in loan and securities
volume.

                                       29

       Net Interest Income. Net interest income, First National's primary source
of revenue, is the difference between the amount of interest and fees generated
by earning assets, primarily loans and securities, that exceeds the interest
cost of deposits and purchased funds.

       Net interest income on a tax equivalent basis for the first nine months
of 1997 totaled $8.6 million, a $735,000 (9.3%) increase over the same period in
1996. The increase resulted from an increase in average earning assets, while
net interest margin declined slightly.

       Net interest income is influenced by changes in both interest rate(s) and
changes in interest-earning assets and interest-bearing liabilities (volume).
First National's average interest-earning assets during the 1997 period
increased $12.2 million over the 1996 period while First National's average
interest-bearing liabilities increased $7.1 million. The difference between the
interest earned and the interest paid on this increased volume resulted in
approximately $735,000 in additional net interest income during 1997.

       The yield on interest-earning assets decreased 4 basis points during the
first nine months of 1997 to 8.42% as compared to 8.46% last year. Loan yields
decreased due to prime rate fluctuations and competitive pressures. Security
yields increased due to the rollover of lower yielding securities to higher
yielding securities. First National's cost of funds increased 28 basis points
during 1997 to 4.57% as compared to 4.29% last year. The increase reflects the
repricing of lower rate deposits to higher rates. Because the increase in the
cost of funds and the decrease in the yield on interest-earning assets, First
National's net interest margin decreased from 4.28% to 4.15% from 1996 to 1997.

       Interest rates decreased during the first half of calendar year 1996,
were steady during the second half of calendar year 1996 and through September
30, 1997. The changes in interest rates have not impacted First National's net
interest margin significantly. However, because First National is
asset-sensitive to interest rates, a change in the direction of rates may have
an impact on First National's net interest margin. Generally when interest rates
increase, First National's net interest margin may increase and if interest
rates decrease, First National's net interest margin may decrease. The impact on
First National's net interest margin is also dependent on the magnitude and
direction of future interest rates, deposit customer alternatives, and First
National's need for liquidity.

       At September 30, 1997, First National has approximately $63 million in
interest-earning assets repricing or maturing within the next year. As a
repricing offset, First National has approximately $66 million in certificates
of deposit maturing in one year and $44 million in savings and checking accounts
whose interest rates may increase or decrease along with other market rates.
Historically, the interest rates paid on savings and checking accounts lag and
do not increase as far as the rates earned on loans and investments. During
1997, strong loan demand has resulted in competitive pressures among banks to
keep deposit rates relatively high and these high rates may have a negative
impact on First National's net interest margin.

       In order to help protect First National against significant rising
interest rates, First National has all of its securities classified as
available-for-sale. If they are sold prior to maturity, First National may
experience losses which may be offset by high interest income when reinvested at
higher yields.

       Provision and Allowance for Loan Losses First National provided
approximately $45,000 for loan losses during the first nine months of 1997
compared to $95,000 of provisions during the same period in 1996. First National
had net loan charge offs of $17,000 in 1997 and $13,000 during 1996. The
provisions should be characterized as general provisions not related to any
specific or impaired loans.

       The allowance for loan losses totaled $970,000 (1.20% of loans) at
September 30, 1997, compared to $912,000 (1.20% of loans) at September 30, 1996.
Based upon management's continuing evaluation of inherent risks in the current
loan portfolio, current levels of classified assets, and economic factors,
management believes the allowance to be adequate to absorb potential losses in
the current portfolio.

     Other Income. Other income, excluding security gains and losses, increased
$213,000 (24%) during 1997 compared to 1996 primarily due to increases in retail
service charges and fees.

       Other Expenses. Other expenses increased $54,000 during the first nine
months of 1997 compared to the same period in 1996. Other expenses as a percent
of average assets was 2.8% in 1997 compared to 2.8% in 1996. First National's
efficiency ratio (operating expenses as a percent of operating income) improved
to 64.4% in 1997 compared to 65.3% last year.

Comparison of Results of Operations for the Years Ended December 31, 1996 and
1995

       Net income for 1996 was $1.5 million, representing a 34.9% increase over
1995 net income of $1.1 million. Net income per share was $95.49 in 1996
compared to $70.80 per share in 1995. For 1996 and 1995, the return on average
assets was 1.07% and 0.94%, respectively. Return on average equity was 23.6% in
1996 compared to 19.3% in 1995. The increase in net income in 1996 was due
primarily to an increase in net interest income and a reduction in expenses. Net
interest income on a tax-equivalent basis increased $563,000 or 11.7% in 1996,
primarily as a result of an increase in average earning assets associated with
purchase and acquisition of the assets and liabilities of Burdett State Bank in
late 1995. Other expenses decreased $7,000 in 1996. First National's efficiency
ratio improved to 61% in 1996 as compared to 68% last year.

       Net Interest Income. Net interest income, First National's primary source
of revenue, is the difference between the amount of interest and fees generated
by earning assets, primarily loans and securities, that exceeds the interest
cost of deposits and purchased funds. Net interest income on a tax equivalent
basis adjusts tax exempt income to an amount which would have been earned had
the income been fully subject to income tax. This discussion is based upon tax
equivalency.

       The following table summarizes the adjustments made to interest income as
reported in the Combined Statements of Operations to arrive at net interest
income. All rates used in the analysis following this table are on a
tax-equivalent basis using a 34% tax rate.

</TABLE> 

         Net interest income during 1996 totaled $5.4 million, a $563,000
(11.7%) increase over 1995. The increase resulted from an increase in average
earning assets, while net interest margin declined slightly. Net interest income
is influenced by changes in both interest rate(s) and changes in
interest-bearing assets and liabilities (volume). First National's average
earning assets in 1996 increased $19.2 million over 1995 while First National's
average interest-bearing liabilities increased $18.2 million. The difference
between the interest earned and the interest paid on this increased volume
resulted in approximately $563,000 in additional net interest income during
1996.

         The yield on earning assets decreased 30 basis points during 1996 to
8.40% as compared to 8.70% last year. Loan yields decreased due to prime rate
fluctuations and competitive pressures. Security yields increased due to the
rollover of lower yielding securities to higher yielding securities. First
National's cost of funds decreased 12 basis points during 1996 to 4.60% as
compared to 4.72% last year. The decrease reflects the repricing of higher rate
deposits to lower rates. Because the decrease in the cost of funds was slightly
lower than the decrease in the yield on earning assets, First National's net
interest margin decreased from 4.50% to 4.26% from 1995 to 1996.

         Interest rates were steady during 1995, decreased during the first half
of 1996, and were steady during the second half of 1996. The changes in interest
rates have not impacted First National's net interest margin significantly.
However, because First National is asset-sensitive to interest rates, a change
in the direction of rates may have an impact on First National's net interest
margin. Generally when interest rates increase, First National's net interest
margin may increase and if interest rates decrease, First National's net
interest margin may decrease. The impact on First National's net interest margin
is also dependent on the magnitude and direction of future interest rates,
deposit customer alternatives, and First National's need for liquidity.

         First National has approximately $65.8 million in earning assets
repricing or maturing within the next year. As a repricing offset, First
National has approximately $52.3 million in certificates of deposit maturing in
one year and $56 million in savings and checking accounts whose interest rates
may increase or decrease along with other market rates. Historically, the
interest rates paid on savings and checking accounts lag and do not increase as
far as the rates earned on loans and investments. During 1996, strong loan
demand has resulted in competitive pressures among banks to keep deposit rates
relatively high and these high rates may have a negative impact on First
National's net interest margin.

         In order to help protect First National against significant rising
interest rates, First National has all of its securities classified as
available-for-sale. If they are sold prior to maturity, First National may
experience losses which may be offset by high interest income when reinvested at
higher yields.

         Provision And Allowance For Loan Losses. First National provided
approximately $110,000 for loan losses during 1996 compared to provisions
totaling $40,000 during 1995. First National had net loan charge offs of $6,000
in 1996 and $176,000 during 1995. The provisions should be characterized as
general provisions not related to any specific or impaired loans.

         The allowance for loan losses totaled $908,000 (1.15% of loans) at
December 31, 1996, compared to $804,000 (1.10% of loans) at December 31, 1995.
Based upon management's continuing evaluation of inherent risks in the current
loan portfolio, current levels of classified assets, and economic factors,
management believes the allowance to be adequate to absorb potential losses in
the current portfolio.

         Noninterest income, excluding security gains and losses, increased
$44,000 (5%) during 1996 compared to 1995. An increase in fiduciary fees was

         Noninterest expenses decreased $7,000 during 1996 compared to 1995. The
decrease in noninterest expenses is primarily attributed to a decrease in the
FDIC insurance assessment of $113,000. This was offset by an increase in
salaries and employee benefits.

         Noninterest expenses as a percent of average assets was 2.9% in 1996
compared to 3.4% in 1995. First National's efficiency ratio (operating expenses
as a percent of operating income) improved to 61% in 1996 compared to 68% last
year.

         Average loans, the largest use of funds, increased $6.6 million or
9.8%. The increase was primarily in commercial, agricultural, and real estate
loans. The loan increase was funded from an increase in deposits.

         Total average deposits increased $17.4 million. Depositors increased
their investment in time certificate of deposits as the interest rate
differential between savings and demand deposit alternatives increased.

         Total stockholders' equity increased $.6 million or 10.1% in 1996 as a
result of the retention of 1996 earnings, partially offset by the payment of
cash dividends and a redemption of preferred stock.

         The total of accruing loans past due 90 days or more and nonaccrual
loans increased $703,000 to $1.4 million at December 31, 1996. The increase in
accruing loans past due 90 days or more was related to one agricultural loan and
one commercial loan. First National does not presently anticipate any
significant losses with respect to these loans or any other assets not reported
above.

Liquidity and Interest Rate Sensitivity

         The primary functions of asset/liability management are to assure
adequate liquidity and to maintain an appropriate balance between interest
earning assets and interest bearing liabilities. Liquidity represents the
ability of First National to meet maturing obligations and existing commitments,
to provide funds necessary to respond to fluctuations in deposit levels, to fund
operations, and to provide for customers' credit needs.

         Liquidity can be provided from both the asset and liability sides of
the balance sheet. On the asset side, liquidity arises primarily through
maturities of investments, daily receipt of principal and interest payments on
loans, and the sale of loans and investments to investors in the secondary
market. Liquidity on the liability side involves the ability of First National
to attract and retain deposits and other funds at a reasonable cost. First
United has not actively sought deposits from outside of its service area or from
large-denomination time certificates of deposits which are available to the
highest bidder. Other sources of liquidity include the purchase of Federal
Funds, repurchase of U.S. government securities, and sale of long-term debt and
common stock. Additional liquidity is also available through the discounting
facilities of the Federal Reserve Bank, and the borrowings from the Federal Home
Loan Bank.

         First National's liquidity position was stable during 1996. First
National believes its liquidity to be strong and more than adequate to meet
future funding needs. Indicators of liquidity include: loan-to-deposit ratio
(loans as a percent of deposits less time deposits $100,000 or more) 73.1% at
December 31, 1996, compared to 68.3% at December 31, 1995; securities maturing
in one year $7.1 million compared to $8.3 million at December 31, 1996 and 1995,
respectively; and interest-bearing deposits in other banks of $4.6 million at
December 31, 1996, compared to $4.2 million at December 31, 1995.

         Interest rate sensitivity is a function of the repricing
characteristics of First National's assets and liabilities -- the time at which,
either at replacement at maturity or during the life of the instrument, interest
bearing assets and liabilities are subject to changes in interest rates.
Examples of interest sensitive assets include loans with floating rates and
assets that will mature within a designated time period. Interest sensitive
liabilities include short-term certificates of deposits and money market
accounts. The difference between the amount of rate sensitive assets and rate
sensitive liabilities, on which interest rates may change with market
fluctuations within a given period of time, is referred to as a rate sensitive
gap. In theory, any gap can have a potential impact on a bank's net interest
income. For example, if interest-sensitive liabilities exceed interest-sensitive
assets, an increase in general interest rates might have an adverse effect on
earnings which might have been realized in the absence of such an interest rate
change. Conversely, a decrease in general interest rates might improve earnings.

<PAGE>
 
         The objective of the interest rate sensitivity process is to maintain
an appropriate balance between First National's interest earning assets and
interest bearing liabilities over a specified time frame. The interest rate
sensitivity analysis presented below represents the relationship at the end of
1996 and 1995 between assets and liabilities that are interest-rate adjustable
within given time periods.

         The preceding chart reflects the contractual maturity and repricing
characteristic of First National's assets and liabilities, and suggests a
liability sensitive structure. Although First National appears somewhat
liability sensitive to interest rates, history has shown that certain interest
rates paid on deposit products lag and do not increase as much as the rates
earned on loans and investments. Therefore, First National's net interest margin
depends not only on the direction and magnitude of future rates, but also
customer alternatives, and need for liquidity. First National's internal
interest rate sensitivity model currently suggests that First National is asset
sensitive. Therefore, in the event of lower interest rates, First National's net
interest margin may decrease.

         First National's one year cumulative interest rate sensitive gap
increased from 22.6% to 26.2% at December 31, 1995 and 1996, respectively. The
increase resulted from the origination of fewer interest rate sensitive loans, a
longer- term security portfolio, and depositors purchasing shorter-term
certificates of deposits during 1996.

Capital Resources

         First National believes a strong capital base is important to the
continued profitability and success of First National, because it promotes
depositor and investor confidence. In addition, it provides a solid foundation
for future growth. First National frequently evaluates the overall adequacy of
its capital position. First National considers among other things, the present
and anticipated needs of the company, current market conditions, and other
relevant factors. Earnings retention continues to be First National's primary
source of increasing capital. However, to remain flexible, First National has
additional authorized but unissued shares of its capital stock. This allows the
Board an opportunity to raise additional capital when necessary and prudent to
do so.

         First National's common stockholders' equity at December 31, 1996, was
$6,693,000 compared to $5,930,000 at December 31, 1995. On a per share basis,
stockholders' equity totaled $436.94 compared to $387.33 on the same dates,
respectively. First National's annualized return on average equity during 1996
totaled 23.6% compared to 19.3% during 1995. The increase in stockholders'
equity was the result of the retention of earnings after redemption of all
outstanding preferred stock in the amount of $473,000 and payment of $153,000 in
cash dividends. Also, during 1996, First National sold 8 shares of new common
stock.

         First National and First United are subject to various regulatory
capital requirements administered by the federal banking agencies. Failure to
meet minimum capital requirements can initiate certain mandatory (and possibly
additional discretionary) actions by regulators that, if undertaken, could have
a direct material affect on First National's financial condition and results of
operations. Under capital adequacy guidelines and the regulatory framework for
prompt corrective action, First National and its subsidiary must each meet
specific capital guidelines that involve quantitative measures of their assets,
liabilities, and certain off-balance-sheet items as calculated under regulatory
accounting practices. First National and its subsidiary's capital amounts and
classifications are also subject to qualitative judgments by the regulators
about components, risk weightings and other factors.

         Quantitative measures established by regulation to ensure capital
adequacy require First National and its subsidiary to maintain minimum amounts
and ratios (set forth in the following table) of total and Tier 1 capital (as
defined in the regulations) to risk-weighted assets (as defined), and of Tier 1
capital (as defined) to average assets (as defined). Management believes, as of
December 31, 1996, that First National and its subsidiary meet all capital
adequacy requirements to which they are subject.

         As of December 31, 1996, the most recent regulatory notification
categorized First United as well capitalized under the regulatory framework for
prompt corrective action. To be categorized as well capitalized the Bank must
maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios
set forth in the table. There are no conditions or events since that
notification that management believes have changed First United's category.

         On a consolidated basis First National has met its minimum regulatory
capital requirements, however, since the financial statements have been prepared
on a combined basis, the capital ratios for First National have not been
presented.

                                  REGULATION

Regulation of First National

         General. First National is a bank holding company within the meaning of
the BHCA. As such, it is registered with the Federal Reserve Board and subject
to Federal Reserve Board regulation, examination, supervision and reporting
requirements. As a bank holding company, First National is required to furnish
to the Federal Reserve Board annual and quarterly reports of its operations at
the end of each period and to furnish such additional information as the Federal
Reserve Board may require pursuant to the BHCA. First National is also subject
to regular examination by the Federal Reserve Board.

         Under the BHCA, a bank holding company must obtain the prior approval
of the Federal Reserve Board before (i) acquiring direct or indirect ownership
or control of any voting shares of any bank or bank holding company if, after
such acquisition, the bank holding company would directly or indirectly own or
control more than 5% of such shares; (2) acquiring all or substantially all of
the assets of another bank or bank holding company; or (3) merging or
consolidating with another bank holding company.

         Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994.
Effective September 29, 1995, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Riegle-Neal Act") allows the Federal Reserve Board
to approve an application of an adequately capitalized and adequately managed
bank holding company to acquire control of, or acquire all or substantially all
of the assets of, a bank located in a state other than such holding company's
home state, without regard to whether the transaction is prohibited by the laws
of any state. The Federal Reserve Board may not approve the acquisition of a
bank that has not been in existence for the minimum time period (not exceeding
five years) specified by the statutory law of the host state. The Riegle-Neal
Act also prohibits the Federal Reserve Board from approving an application if
the applicant (and its depository institution affiliates) controls or would
control more than 10% of the insured deposits in the United States or 30% or
more of the deposits in the target bank's home state or in any state in which
the target bank maintains a branch. The Riegle-Neal Act does not affect the
authority of states to limit the percentage of total insured deposits in the
state which may be held or controlled by a bank or bank holding company to the
extent such limitation does not discriminate against out-of-state banks or bank
holding companies. Individual states may also waive the 30% state-wide
concentration limit contained in the Riegle-Neal Act.

                                       38
<PAGE>
 
         Additionally, beginning June 1, 1997, the federal banking agencies were
authorized to approve interstate merger transactions without regard to whether
such transaction is prohibited by the law of any state, unless the home state of
one of the banks opted out of the Riegle-Neal Act by adopting a law after the
date of enactment of the Riegle-Neal Act and prior to June 1, 1997 which applied
equally to all out-of-state banks and expressly prohibited merger transactions
involving out-of-state banks. Interstate acquisitions of branches are permitted
only if the law of the state in which the branch is located permits such
acquisitions. Interstate mergers and branch acquisitions are also subject to the
nationwide and statewide insured deposit concentration amounts described above.

         The BHCA also prohibits, with certain exceptions, a bank holding
company from acquiring direct or indirect ownership or control of more than 5%
of the voting shares of a company that is not a bank or a bank holding company,
or from engaging directly or indirectly in activities other than those of
banking, managing or controlling banks, or providing services for its
subsidiaries. The principal exceptions to these prohibitions involve certain
non-bank activities which, by statute or by Federal Reserve Board regulation or
order, have been identified as activities closely related to the business of
banking or managing or controlling banks. The activities of First National are
subject to these legal and regulatory limitations under the BHCA and the Federal
Reserve Board's regulations thereunder. Notwithstanding the Federal Reserve
Board's prior approval of specific nonbanking activities, the Federal Reserve
Board has the power to order a holding company or its subsidiaries to terminate
any activity, or to terminate its ownership or control of any subsidiary, when
it has reasonable cause to believe that the continuation of such activity or
such ownership or control constitutes a serious risk to the financial safety,
soundness or stability of any bank subsidiary of that holding company.

         Capital Adequacy. The Federal Reserve Board has adopted guidelines
regarding the capital adequacy of bank holding companies, which require bank
holding companies to maintain specified minimum ratios of capital to total
assets and capital to risk-weighted assets. See "-- Regulation of First 
United -- Capital Adequacy."

         Dividends and Distributions. The Federal Reserve Board has the power to
prohibit dividends by bank holding companies if their actions constitute unsafe
or unsound practices. The Federal Reserve Board has issued a policy statement on
the payment of cash dividends by bank holding companies, which expresses the
Federal Reserve Board's view that a bank holding company should pay cash
dividends only to the extent that the company's net income for the past year is
sufficient to cover both the cash dividends and a rate of earning retention that
is consistent with the company's capital needs, asset quality, and overall
financial condition.

         Bank holding companies are required to give the Federal Reserve Board
notice of any purchase or redemption of their outstanding equity securities if
the gross consideration for the purchase or redemption, when combined with the
net consideration paid for all such purchases or redemptions during the
preceding 12 months, is equal to 10% or more of the bank holding company's
consolidated net worth. The Federal Reserve Board may disapprove such a purchase
or redemption if it determines that the proposal would violate any law,
regulation, Federal Reserve Board order, directive, or any condition imposed by,
or written agreement with, the Federal Reserve Board. Bank holding companies
whose capital ratios exceed the thresholds for "well capitalized" banks on a
consolidated basis are exempt from the foregoing requirement if they were rated
composite 1 or 2 in their most recent inspection and are not the subject of any
unresolved supervisory issues.

Regulation of First United

         General. As a national bank, First United is subject to the primary
supervision of the OCC under the National Bank Act. The OCC regularly examines
the operations of First United, including but not limited to capital adequacy,
reserves, loans, investments and management practices. These examinations are
for the protection of First United's depositors and not its shareholders. In
addition, First United is required to furnish quarterly and annual reports to
the OCC. The OCC's enforcement authority includes the power to remove officers
and directors and the authority to issue cease-and-desist orders to prevent a
bank from engaging in unsafe or unsound practices or violating laws or
regulations governing its business.

         First United is a member of the Federal Reserve System and its deposits
are insured by the FDIC to the legal maximum of $100,000 for each insured
depositor. Some of the aspects of the lending and deposit business of First
United that are subject to regulation by the Federal Reserve Board and the FDIC
include reserve requirements and disclosure requirements in connection with
personal and mortgage loans and savings deposit accounts. In addition, First
United is subject to numerous federal and state laws and regulations which set
forth specific restrictions and procedural requirements with respect to the
establishment of branches, investments, interest rates on loans, credit
practices, the disclosure of credit terms and discrimination in credit
transactions.

         Capital Adequacy. The Federal Reserve Board and the OCC have
established guidelines with respect to the maintenance of appropriate levels of
capital by bank holding companies and national banks, respectively. The
regulations impose two sets of capital adequacy requirements: minimum leverage
rules, which require bank holding companies and banks to maintain a specified
minimum ratio of capital to total assets, and risk-based capital rules, which
require the maintenance of specified minimum ratios of capital to
"risk-weighted" assets.

         The regulations of the Federal Reserve Board and the OCC require bank
holding companies and national banks, respectively, to maintain a minimum
leverage ratio of "Tier 1 capital" (as defined in the risk-based capital
guidelines discussed in the following paragraphs) to total assets of 3.0%.
Although setting a minimum 3.0% leverage ratio, the capital regulations state
that only the strongest bank holding companies and banks, with composite
examination ratings of 1 under the rating system used by the federal bank
regulators, would be permitted to operate at or near such minimum level of
capital. All other bank holding companies and banks are expected to maintain a
leverage ratio of at least 1% to 2% above the minimum ratio, depending on the
assessment of an individual organization's capital adequacy by its primary
regulator. Any bank or bank holding company experiencing or anticipating
significant growth would be expected to maintain capital well above the minimum
levels. In addition, the Federal Reserve Board has indicated that whenever
appropriate, and in particular when a bank holding company is undertaking
expansion, seeking to engage in new activities or otherwise facing unusual or
abnormal risks, it will consider, on a case-by-case basis, the level of an
organization's ratio of tangible Tier 1 capital (after deducting all
intangibles) to total assets in making an overall assessment of capital.

         The risk-based capital rules of the Federal Reserve Board and the OCC
require bank holding companies and state member banks to maintain minimum
regulatory capital levels based upon a weighting of their assets and off-balance
sheet obligations according to risk. The risk-based capital rules have two basic
components: a core capital (Tier 1) requirement and a supplementary capital
(Tier 2) requirement. Core capital consists primarily of common stockholders'
equity, certain perpetual preferred stock (which must be noncumulative with
respect to banks), and minority interests in the equity accounts of consolidated
subsidiaries; less all intangible assets, except for certain purchased mortgage
servicing rights and purchased credit card relationships. Supplementary capital
elements include, subject to certain limitations, the allowance for losses on
loans and leases; perpetual preferred stock that does not qualify as Tier 1
capital and long-term preferred stock with an original maturity of at least 20
years from issuance; hybrid capital instruments, including perpetual debt and
mandatory convertible securities; and subordinated debt and intermediate-term
preferred stock.

         The risk-based capital regulations assign balance sheet assets and
credit equivalent amounts of off-balance sheet obligations to one of four broad
risk categories based principally on the degree of credit risk associated with
the obligor. The assets and off-balance sheet items in the four risk categories
are weighted at 0%, 20%, 50% and 100%. These computations result in the total
risk-weighted assets. The risk-based capital regulations require all banks and
bank holding companies to maintain a minimum ratio of total capital to total
risk-weighted assets of 8%, with at least 4% as core capital. For the purpose of
calculating these ratios: (i) supplementary capital will be limited to no more
than 100% of core capital; and (ii) the aggregate amount of certain types of
supplementary capital will be limited. In addition, the risk-based capital
regulations limit the allowance for loan losses includable as capital to 1.25%
of total risk-weighted assets.

                                       40
<PAGE>
 
         OCC regulations and guidelines additionally specify that national banks
with significant exposure to declines in the economic value of their capital due
to changes in interest rates may be required to maintain higher risk-based
capital ratios. The federal banking agencies, including the OCC, have proposed a
system for measuring and assessing the exposure of a bank's net economic value
to changes in interest rates. The federal banking agencies, including the OCC,
have stated their intention to propose a rule establishing an explicit capital
charge for interest rate risk based upon the level of a bank's measured interest
rate risk exposure after more experience has been gained with the proposed
measurement process. Federal Reserve Board regulations do not specifically take
into account interest rate risk in measuring the capital adequacy of bank
holding companies.

         The OCC has issued final regulations which classify national banks by
capital levels and which provide for the OCC to take various prompt corrective
actions to resolve the problems of any bank that fails to satisfy the capital
standards. Under such regulations, a well-capitalized bank is one that is not
subject to any regulatory order or directive to meet any specific capital level
and that has or exceeds the following capital levels: a total risk-based capital
ratio of 10%, a Tier 1 risk-based capital ratio of 6%, and a leverage ratio of
5%. An adequately capitalized bank is one that does not qualify as
well-capitalized but meets or exceeds the following capital requirements: a
total risk-based capital ratio of 8%, a Tier 1 risk-based capital ratio of 4%,
and a leverage ratio of either (i) 4% or (ii) 3% if the bank has the highest
composite examination rating. A bank not meeting these criteria is treated as
undercapitalized, significantly undercapitalized, or critically undercapitalized
depending on the extent to which the bank's capital levels are below these
standards. A national bank that falls within any of the three undercapitalized
categories established by the prompt corrective action regulation will be
subject to severe regulatory sanctions. As of September 30, 1997, First United
was well-capitalized as defined by the OCC's regulations.

         For information regarding First United's compliance with its regulatory
capital requirements, see Note 10 of Notes to Combined Financial Statements.

         Branching. Under the McFadden Act of 1927, national banks may only
establish branches to the extent specifically authorized by statute for banks
chartered by the state in which the national bank is located and subject to the
restrictions as to location imposed by state law on state banks. The Riegle-Neal
Act authorizes the OCC and FDIC to approve interstate branching de novo by
national and state banks, respectively, only in states which specifically allow
for such branching. The Riegle-Neal Act also requires the appropriate federal
banking agencies to prescribe regulations by June 1, 1997 which prohibit any
out-of-state bank from using the interstate branching authority primarily for
the purpose of deposit production. These regulations must include guidelines to
ensure that interstate branches operated by an out-of-state bank in a host state
are reasonably helping to meet the credit needs of the communities which they
serve.

         Dividend Limitations. Pursuant to the National Bank Act, no national
bank may pay dividends from its paid-in capital. All dividends must be paid out
of current or retained net profits, after deducting reserves for losses and bad
debts. The National Bank Act further restricts the payment of dividends out of
net profits by prohibiting a national bank from declaring a dividend on its
shares of common stock until the surplus fund equals the amount of capital stock
or, if the surplus fund does not equal the amount of capital stock, until
one-tenth of a bank's net profits for the preceding half year in the case of
quarterly or semi-annual dividends, or the preceding two half-year periods in
the case of annual dividends, are transferred to the surplus fund. Prior OCC
approval is required for the payment of a dividend if the total of all dividends
declared by a national bank in any calendar year would exceed the total of its
net profits for that year combined with its net profits for the two preceding
years, less any required transfers to surplus or a fund for the retirement of
any preferred stock. In addition, First United is prohibited by federal statute
from paying dividends or making any other capital distribution that would cause
First United to fail to meet its regulatory capital requirements. Further, the
OCC also has authority to prohibit the payment of dividends by a national bank
when it determines such payment to be an unsafe and unsound banking practice.

         Deposit Insurance. The deposits of First United are insured up to
applicable limits by the FDIC through the Bank Insurance Fund (the "BIF"). First
United is required to pay semi-annual assessments based on a percentage of its
insured deposits to the FDIC for insurance of its deposits by the BIF.

                                       41
<PAGE>
 
         Under the risk-based deposit insurance assessment system adopted by the
FDIC, the assessment rate for an insured depository institution depends on the
assessment risk classification assigned to the institution by the FDIC, which is
determined by the institution's capital level and supervisory evaluations. Based
on the data reported to regulators for the date closest to the last day of the
seventh month preceding the semi-annual assessment period, institutions are
assigned to one of three capital groups -- "well capitalized," "adequately
capitalized" or "undercapitalized." Within each capital group, institutions are
assigned to one of three subgroups on the basis of supervisory evaluations by
the institution's primary supervisory authority and such other information as
the FDIC determines to be relevant to the institution's financial condition and
the risk posed to the deposit insurance fund.

         Transactions with Affiliates. Transactions between a national bank and
any affiliate are governed by Sections 23A and 23B of the Federal Reserve Act.
An affiliate of a national bank is any company or entity which controls, is
controlled by or is under common control with the national bank. In a holding
company context, the parent holding company of a national bank (such as First
National) and any companies which are controlled by such parent holding company
are affiliates of the national bank. Generally, Sections 23A and 23B (i) limit
the extent to which the bank or its subsidiaries may engage in "covered
transactions" with any one affiliate to an amount equal to 10% of such bank's
capital stock and surplus, and contain an aggregate limit on all such
transactions with all affiliates to an amount equal to 20% of such capital stock
and surplus and (ii) require that all such transactions be on terms
substantially the same, or at least as favorable, to the institution or
subsidiary as those provided to a non-affiliate. The term "covered transaction"
includes the making of loans, purchase of assets, issuance of a guarantee and
similar other types of transactions. In addition to the restrictions imposed by
Sections 23A and 23B, no national bank may (i) loan or otherwise extend credit
to an affiliate, except for any affiliate which engages only in activities which
are permissible for bank holding companies, or (ii) purchase or invest in any
stocks, bonds, debentures, notes or similar obligations of any affiliate, except
for affiliates which are subsidiaries of the national bank. The BHCA further
prohibits a depository institution from extending credit to or offering any
other services, or fixing or varying the consideration for such extension of
credit or service, on the condition that the customer obtain some additional
service from the institution or certain of its affiliates or not obtain services
of a competitor of the institution, subject to certain exceptions.

         Loans to Directors, Executive Officers and Principal Stockholders.
National banks are also subject to the restrictions contained in Section 22(h)
and 22(g) of the Federal Reserve Act on loans to executive officers, directors
and principal stockholders. Under Section 22(h), loans to a director, executive
officer or greater than 10% stockholder of a national bank and certain
affiliated interests of the foregoing, may not exceed, together with all other
outstanding loans to such person and affiliated interests, the bank's loans to
one borrower limit (generally equal to 15% of the institution's unimpaired
capital and surplus) and all loans to such persons may not exceed the
institution's unimpaired capital and unimpaired surplus. Section 22(h) also
prohibits loans, above amounts prescribed by the appropriate federal banking
agency, to directors, executive officers and greater than 10% stockholders of a
national bank, and their respective affiliates, unless such loan is approved in
advance by a majority of the board of directors of the association with any
"interested" director not participating in the voting. The Federal Reserve Board
has prescribed the loan amount (which includes all other outstanding loans to
such person), as to which such prior board of director approval if required, as
being the greater of $25,000 or 5% of capital and surplus (up to $500,000).
Further, the Federal Reserve Board pursuant to Section 22(h) requires that loans
to directors, executive officers and principal stockholders be made on terms
substantially the same as offered in comparable transactions to other persons
unless the loan is made pursuant to a benefit or compensation plan that is
widely available to other employees and does not give preference to insiders.
Section 22(h) also prohibits a depository institution from paying the overdrafts
of any of its executive officers or directors. Section 22(g) of the Federal
Reserve Act requires that loans to executive officers of depository institutions
be approved by the board of directors of the institution, and imposes reporting
requirements for and additional restrictions on the type, amount and terms of
credits to such officers. In addition, Section 106 of the BHCA prohibits
extensions of credit to executive officers, directors, and greater than 10%
stockholders of a depository institution by any other institution which has a
correspondent banking relationship with the institution, unless such extension
of credit is on substantially the same terms as those prevailing at the time for
comparable transactions with other persons and does not involve more than the
normal risk of repayment or present other unfavorable features.

                       COMPARISON OF STOCKHOLDER RIGHTS

         Introduction. Upon consummation of the Merger, the holders of First
National Common Stock, whose rights are presently governed by Kansas law and
First National's Articles of Incorporation and Bylaws, will become stockholders
of Commercial, a Nebraska corporation. Accordingly, their rights will be
governed by Nebraska law and the Articles of Incorporation (as amended by the
stockholders of Commercial on November 18, 1997) and Bylaws of Commercial.
Certain differences arise between the Articles of Incorporation and Bylaws of
First National and the Articles of Incorporation and Bylaws of Commercial. The
following discussion is not intended to be a complete statement of all
differences affecting the rights of stockholders, but summarizes material
differences and is qualified in its entirety by reference to the Articles of
Incorporation and Bylaws of Commercial and the Articles of Incorporation and
Bylaws of First National. See "Available Information."

         Issuance of Common Stock. The Articles of Incorporation of Commercial
authorize the issuance of 50,000,000 shares of Commercial Common Stock and
10,000,000 shares of preferred stock, par value $0.01 per share. The Articles of
Incorporation of First National authorize the issuance of 20,000 shares of
Common Stock, par value $1.00 per share, 52,483 shares of Class A 10% Preferred
Stock, par value $17.15 per share, 2,250,000 shares of Class B 7% Preferred
Stock, par value $1.00 per share, 12,500 shares of Class C 7% Preferred Stock,
par value $10.00 per share and 2,000 shares of Class D 10% Preferred Stock, par
value $10.00 per share. On January 5, 1998, 32,595,800 and 15,317.65 shares of
Commercial Common Stock and First National Common Stock, respectively, were
issued and outstanding. Neither Commercial nor First National had any shares of
preferred stock outstanding. Under Commercial's Articles of Incorporation and
First National's Articles of Incorporation, Commercial and First National are
authorized to issue additional shares of capital stock up to the amount
authorized without stockholder approval. Under the rules of the NYSE, however,
shares issuances equal to 20% or more of the shares outstanding immediately
prior thereto must be approved by stockholders.

         Holders of both Commercial and First National Common Stock are entitled
to one vote per share on all matters submitted to vote to the stockholders,
other than during the election of directors, where voting rights are cumulative.

         Preemptive Rights. Neither the holders of First National Common Stock
nor the holders of Commercial Common Stock have any preemptive or preferential
right to purchase or to subscribe for additional shares of First National Common
Stock or Commercial Common Stock, respectively, or any other securities that
either First National or Commercial may issue.

         Number and Terms of Directors. The Board of Directors of Commercial is
divided into three classes with three separate terms, so that only one class is
elected at each annual meeting of stockholders. Commercial's Board of Directors
consists of between nine and twelve persons with the precise number to be
specified in the Bylaws. Action to change the number of directors (outside the
range of 9 to 12) must be by the affirmative vote of not less than 75% of all
outstanding shares of Commercial Common Stock. First National's Board consists
of between five and fifteen persons with the precise number to be specified in
the Bylaws without separate classes of directors. Action to change the number of
First National directors requires a majority vote of the directors then in
office.

         Advance Notice Requirements for Nominations of Directors and
Presentation of New Business at Annual Meeting of Stockholders. Commercial's
Bylaws provide that any new business to be taken up at an annual meeting shall
be made in writing and filed with the Secretary of Commercial at least twenty
days before the date of the annual meeting. First National's Bylaws do not
provide for nominations for the election of directors and proposals for any new
business to be taken up at any annual or special meeting of stockholders.

         Removal of Directors. The KGCC, provides for the removal of any First
National director, with or without cause, by an affirmative vote of not less
than a majority of total votes eligible to be cast by stockholders, except where
a corporation has cumulative voting for directors and less than the entire board
is being removed, then a director may only be removed without cause when the
votes cast against such director's removal would be sufficient to elect such
director if then cumulatively voted at an election of directors. The Articles
and Bylaws of Commercial provide for removal of any director or the entire Board
of Directors at any time with an affirmative vote of the holders of seventy-five
percent (75%) or more of the shares entitled to vote.

                                       45
<PAGE>
 
         Special Meetings. Under the First National Bylaws, special meetings of
stockholders may only be called by resolution of the Board of Directors, the
Chairman of the Board, the President, the Secretary, or by the holders of not
less than twenty-five percent (25%) of outstanding stock entitled to vote at
such meeting. A special meeting of Commercial's stockholders may be called for
any purpose and at any time by a majority of the members of the Board of
Directors, by the holders of seventy-five percent (75%) or more of shares
entitled to vote at such meeting, or by a committee of the Board of Directors
which has been duly designated by the Board of Directors to have the power to
call such special meetings. No other person or persons may call special
meetings.

         Approval of Business Combination. Under the KGCC, a business
combination involving First National will require that each constituent
corporation's board of directors adopt a resolution approving the Plan of
Merger, and then following board approval, the business combination must be
submitted to the stockholders of each constituent corporation for approval which
will require the affirmative vote of a majority of holders of the outstanding
shares of voting stock of each constituent corporation. Unless otherwise
provided in the Articles of Incorporation of the surviving corporation, no vote
of stockholders shall be required of the surviving corporation to authorize the
merger if the agreement of merger does not amend in any respect the articles of
incorporation of such constituent corporation, each share of stock of such
constituent corporation outstanding immediately prior to the effective date of
the merger is to be an identical outstanding or treasury share of the surviving
corporation after the effective date of the merger, and either no shares of
common stock of the surviving corporation and no shares, securities or
obligations convertible into such stock are to be issued or delivered under the
plan of merger, or the authorized unissued shares or the treasury shares of
common stock of the surviving corporation to be issued or delivered under the
plan of merger plus those initially issuable upon conversion of any other
shares, securities or obligations to be issued or delivered under such plan do
not exceed 20% of the shares of common stock of such constituent corporation
outstanding immediately prior to the effective date of the merger.

         Commercial's Articles of Incorporation require that any merger,
reorganization, or consolidation, or any sale, lease, exchange, mortgage,
pledge, transfer or other disposition of at least 25% of the fair market value
of the total assets of Commercial with any affiliate or any person who
beneficially owns in the aggregate 20% or more of the outstanding shares of
voting stock of Commercial must first be approved by the affirmative vote of the
holders of not less than 75% of the outstanding shares of voting stock and the
affirmative vote of the holders of not less than a majority of the outstanding
shares of voting stock held by stockholders other than a principal shareholder 
(a person who owns at least 20% of the outstanding shares of Commercial's voting
stock). Commercial's Articles of Incorporation also require that certain fair
price criteria designed to ensure that Commercial's stockholders receive a fair
price for their shares in a business combination be met, unless a business
combination is first approved by three-quarters of the board of directors who
were directors prior to the time the person became a principal shareholder.

         Rights Plan. On December 19, 1988, the Board of Directors of Commercial
adopted a Shareholder Rights Plan (the "Rights Plan") and declared a
distribution of stock purchase rights (the "Rights") payable to stockholders of
record on December 30, 1988. The Rights consist of primary rights (the "Primary
Rights"), which generally entitle the holders thereof to purchase shares of
Commercial Common Stock at 20% of the market price of such shares in the event
any person acquires an interest in 15% or more of Commercial Common Stock
without complying with a procedure intended to ensure fair treatment of all
stockholders of Commercial, and secondary rights (the "Secondary Rights"), which
generally entitle the holders thereof to purchase shares of Series A Junior
Participating Cumulative Preferred Stock of Commercial (the "Preferred Shares")
in the event a person acquires an interest in 25% or more of the outstanding
shares of Commercial Common Stock without complying with such procedural
requirements. The December 30, 1988 distribution consisted of one Primary Right
and One Secondary Right for each share of Commercial Common Stock outstanding on
that date and, subject to adjustment under certain circumstances, unless the
Rights expire or are earlier redeemed, one Primary Right and one Secondary Right
shall be issued with each share of Commercial Common Stock issued following
December 30, 1988 until the Rights become exercisable under the terms of the
Rights Plan.

                                       46
<PAGE>
 
         The Primary Rights will become exercisable, subject to extension, 
10 business days following a public announcement that any person (other than
certain entities who beneficially owned more than 15% of Commercial's
outstanding Commercial Common Stock as of the date of adoption of the Rights
Plan and certain persons who acquire their shares directly from Commercial) has
acquired, or has obtained the right to acquire, beneficial ownership of 15% or
more of the outstanding shares of Commercial Common Stock and has not complied
with the procedural requirements set forth in the Rights Plan (such person being
referred to as a "15% Person"). Secondary Rights will become exercisable upon
the earlier of (i) one business day following a public announcement that any
person (other than Commercial or certain related entities) has acquired, or has
obtained the right to acquire, beneficial ownership of 25% or more of the
outstanding shares of Commercial Common Stock, provided that such acquisition is
not deemed a "Fair Offer," as described in the Rights Plan (such person being
known as a "25% Person"), or (ii) one business day following the commencement of
a tender offer, other than a Fair Offer, or exchange offer, the consummation of
which would result in the beneficial ownership of 25% or more of the outstanding
shares of Commercial Common Stock by any person other than Commercial or certain
related entities. A public announcement for this purpose shall be made by
Commercial or, as the case may be, by a 15% Person or a 25% Person.

         The number of shares which may be purchased upon exercise of each
Primary Right is determined by dividing (i) that number of shares which equals
50% of the outstanding shares of Commercial Common Stock, as of the date a
person became a 15% Person, by (ii) the number of Primary Rights outstanding,
exclusive of Primary Rights beneficially owned by the 15% Person, which shall
become void. The per share exercise price of shares issued upon the exercise of
a Primary Right is 20% of the market price of such shares as of the date the 15%
Person became a 15% Person.

         Unless the Secondary Rights are earlier redeemed, in the event a person
becomes a 25% Person, each holder of a Secondary Right (other than Secondary
Rights beneficially owned by such 25% Person, which will thereafter become void)
will have the Right to purchase one-hundredth of a share of Preferred Shares at
a price of $42.00 per one-hundredth of a share. Unless the Secondary Rights are
earlier redeemed, in the event that (i) Commercial is the surviving corporation
in a merger with a 25% Person and Commercial Common Stock is not changed or
exchanged in such merger, (ii) a 25% Person engages in one of a number of "self
dealing" transactions, including certain preferential sales, transfers or
exchanges of Commercial assets or securities, (iii) during such time as there is
a 25% Person, there shall be any reclassification of securities or
recapitalization of Commercial or any merger or consolidation of Commercial with
any of its subsidiaries or any other transaction or series of transactions which
has the effect of increasing by more than 1% the proportionate share of the
outstanding shares of any class of equity securities or of securities
exercisable for or convertible into securities of Commercial or any of its
subsidiaries which is beneficially owned by a 25% Person, or (iv) a person
(other than Commercial or certain related entities) becomes the beneficial owner
of 25% or more of the outstanding shares of Commercial Common Stock (other than
pursuant to certain transactions set forth in the Rights Plan), then each holder
of a Secondary Right will have the right to receive, upon exercise and payment
of the Secondary Right exercise price, Commercial Common Stock having a value
equal to two times the then current Secondary Right exercise price.

         In the event Commercial is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earnings
power is sold, each holder of a Secondary Right will thereafter have the right
to receive, upon the exercise and payment of the Secondary Right exercise price,
that number of shares of common stock of the acquiring company which at the time
of such transaction has a value equal to two times the then current Secondary
Right exercise price.

         A majority of the independent directors of Commercial may authorize the
redemption of either or both of the Primary or Secondary Rights at a price of
$0.01 per Right at any time prior to the close of business on the tenth business
day, subject to extension, following the date of a public announcement that any
person has become a 15% Person, other than pursuant to certain cash tender
offers described in the Rights Plan, and at any time prior to the public
announcement that any person has become a 25% Person, other than pursuant to
such a cash tender offer. Commercial's right of redemption with respect to the
Secondary Rights will be reinstated if each 25% Person reduces its beneficial
ownership to less than 15% of Commercial Common Stock in a transaction not
involving a purchase by Commercial or its 

                                       47
<PAGE>
 
subsidiaries. Immediately upon any redemption of the Rights, the right to
exercise the Rights will terminate and the only right of the holders thereof
will be to receive the redemption price.

         The terms of the Rights may be amended by the Board of Directors of
Commercial without the consent of the holders of the Rights, except that
following the date on which the Rights become exercisable, such amendment may
not adversely affect the interests of the holders of the Rights.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of Commercial (other than rights resulting from such
holder's ownership of Commercial Common Stock), including, without limitation,
the right to vote or to receive dividends.

         The Rights have certain anti-takeover effects. The Rights could cause
substantial dilution to a person or group that attempts to acquire Commercial
without conditioning the offer on the Rights being redeemed or substantially all
of the Rights being acquired.

         First National does not have a stockholder rights plan.

         Amendment of Bylaws. The Board of Directors of First National may
adopt, alter, amend, or repeal the Bylaws by a majority vote of directors
present at a regular or special meeting.

         The Board of Directors of Commercial are authorized to make, repeal,
alter, amend or rescind any or all of the Bylaws of the corporation.
Stockholders may make, repeal, alter, amend or rescind the Bylaws only upon a
seventy-five percent (75%) or more of the total voting power of outstanding
shares of each class of capital stock entitled to vote.

         Amendment of Articles of Incorporation. Under the KGCC, a Kansas
Corporation, such as First National, has the right to amend, alter, change or
repeal any provision of its Articles, provided that first there is an resolution
adopted by a majority of the board of directors, and then the matter is
subsequently approved by an affirmative vote of a majority of stockholders
entitled to vote at the election of directors. The holders of outstanding shares
of a class shall be entitled to vote as a class upon a proposed amendment to the
Articles of Incorporation, whether or not entitled to vote by the Articles of
Incorporation, if the amendment would increase or decrease the aggregate number
of authorized shares of such class, increase or decrease the par value of the
shares of such class, or alter or change the powers, preferences or special
rights of the shares of such class so as to affect them adversely.

         Commercial in its Articles reserved the right to amend, alter, change,
or repeal any provision contained in its Articles of Incorporation except in
Article VII (dealing with the number of directors of the corporation), 
Article VIII (dealing with the classified board of directors), Article IX
(dealing with the removal of directors), Article X (dealing with filing
vacancies on the Board of Directors and newly created directorships), Article XI
(dealing with the power to call special meetings of the stockholders), Article
XII (dealing with the amount of stock which can be acquired), Article XIII
(dealing with the approval of Business Combinations),Article XIV (dealing with
the market price of stock involved in any business combination), Article XV 
(dealing with the amendment of Bylaws by directors and by stockholders) and
Article XVI (the provision explaining these exceptions), may not be repealed or
amended in any respect, unless such repeal or amendment is approved by the
affirmative vote of the holders of not less than seventy-five percent (75%) of
all outstanding shares of stock of the corporation entitled to vote generally,
other than in the election of directors, and the affirmative vote of the holders
of not less than a majority of the outstanding shares of stock of the
corporation entitled to vote generally, other than election of directors and
other than Principal Shareholders.

         Action of Stockholders Without a Meeting. The Articles and Bylaws of
First National provide that no action required to be taken or which may be taken
at any annual or special meeting of stockholders of the corporation may be taken
without a meeting. The power for stockholders to consent in writing to take
action without a meeting is expressly denied.

                                       48
<PAGE>
 
         The Bylaws of Commercial permit any action required to be taken at a
meeting of the stockholders, or any action which may be taken at a meeting of
the stockholders, may be taken without a meeting if a consent in writing,
setting for the action so taken, shall be signed by all of the stockholders
entitled to vote. Such written stockholder consent will have the effect of a
unanimous stockholder vote.


                                 LEGAL MATTERS

         The legality of the Commercial Common Stock to be issued pursuant to
the Merger Agreement will be passed upon for Commercial by Fitzgerald, Schorr,
Barmettler & Brennan, P.C. Omaha, Nebraska.

         Certain other legal matters in connection with the Merger will be
passed upon for Commercial by Housley Kantarian & Bronstein, P.C., Washington,
D.C., and for First National by Stinson, Mag & Fizzell, P.C., Kansas City,
Missouri.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders
 of First National Bank Shares, Ltd.
Great Bend, Kansas

We have audited the accompanying combined statement of financial condition of
First National Bank Shares, Ltd. and First United National Bank and Trust
Company (First National) as of December 31, 1996, and the related combined
statements of operations, stockholders' equity, and cash flows for the year then
ended. These financial statements are the responsibility of First National's
management. Our responsibility is to express an opinion on these 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 financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, such combined financial statements present fairly, in all
material respects, the financial position of First National as of December 31,
1996, and the results of its operations and its cash flows for the year then
ended in conformity with generally accepted accounting principles.

NOTES TO COMBINED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995
(COLUMNAR AMOUNTS IN THOUSANDS)
- --------------------------------------------------------------------------------

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   BASIS OF PRESENTATION AND NATURE OF BUSINESS - The combined financial
   statements of First National Bank Shares, Ltd. (FNBS), a bank holding
   company, are the separate financial statements relating to FNBS's wholly-
   owned subsidiary, First United National Bank and Trust Company (FUNB) and
   FNBS's activities as the parent company of its subsidiary.  FNBS's investment
   in its subsidiary other than FUNB and the operations of that other subsidiary
   have been carved out of FNBS's financial statements.  The combined financial
   statements present the financial condition, results of operations and cash
   flows of FNBS as if it were a separate entity for all periods presented.
   FNBS's historical basis in the assets and liabilities have been carried over.
   All material intercompany transactions and balances have been eliminated in
   combination.

   The unaudited combined financial statements furnished herein reflect all 
   adjustments, which are, in the opinion of management, necessary to fairly
   present the financial results for the unaudited period presented.

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

   CASH EQUIVALENTS - For purposes of reporting cash flows, cash equivalents
   consist of highly liquid investments with an original maturity of 90 days or
   less.

   SECURITIES - All securities are available for sale and are carried at fair
   value.  Unrealized holding gains and losses are excluded from earnings and
   reported net of deferred taxes, as a separate component of stockholders'
   equity until realized.  Gains and losses on the sale of investment securities
   are computed under the specific identification method. Premiums and discounts
   are amortized over the contractual lives of the related securities on the
   level yield method. Unrealized losses on securities, if any, reflecting a
   decline in the fair value of such securities to be other than temporary, are
   charged against income. Realized gains or losses on securities available for
   sale are based on the specific identification method and are included in
   results of operations on the trade date.

   LOANS - Loans are stated at their principal amount outstanding.  Mortgage
   loans held for sale are valued at the lower of aggregate cost or market.

   Interest on loans and amortization of unearned income is credited to income
   on a daily basis, based on principal amounts outstanding at applicable rates.
   The accrual of interest income on impaired loans is discontinued when
   management has determined that the borrower may be unable to meet payments as
   they become due.  Accrual of interest income is generally discontinued when a
   loan becomes 90 days past due as to principal or interest.  When interest
   income accruals are discontinued, interest credited to income in the current
   year is reversed, and interest accrued in the prior year is charged to the
   allowance for loan losses.  Interest income is subsequently recognized only
   to the extent cash payments are received.

   ALLOWANCE FOR LOAN LOSSES - The management of credit risk is the
   responsibility of FNBS's Executive Committee.  Such Committee has established
   maximum credit limits for single borrowers and for loan 

                                      F-6
<PAGE>
 
   classifications generally. The comparison of limits and actual levels of
   activity is reviewed by the Board of Directors on a regular basis.

   The allowance for loan losses (the allowance) is intended to absorb future
   possible losses in the loan portfolio.  Provisions for loan losses, which are
   charged to operating expenses and added to the allowance, are based upon
   several factors including actual loss experience, current and forecasted
   economic conditions, a review of the quality of the loan portfolio, and other
   pertinent factors.  The balance of the allowance is considered by management
   adequate to absorb losses which may exist in the loan portfolio at December
   31, 1996.  In connection with the determination of the allowances for loan
   losses and real estate owned, management obtains independent appraisals for
   significant properties.

   SFAS No. 114, Accounting by Creditors for Impairment of a Loan and SFAS No.
   118 Accounting by Creditors for Impairment of a Loan - Income Recognition and
   Disclosures, were adopted January 1, 1995.  Under these statements, loans
   considered to be impaired are reduced to the present value of expected future
   cash flows or to the fair value of collateral, by allocating a portion of the
   allowance for loan losses to such loans.  If these allocations cause the
   allowance for loan losses to require an increase, such increase is reported
   as provision for loan losses. Residential mortgage loans and consumer loans
   are excluded from SFAS No. 114 as they are evaluated collectively for
   impairment since they are homogeneous and generally carry smaller individual
   balances. The carrying values of impaired loans are periodically adjusted to
   reflect cash payments, revised estimates of future cash flows and increases
   in the present value of expected cash flows due to the passage of time. Cash
   payments are reported as reductions in carrying value, while increases or
   decreases due to changes in estimates of future payments and due to the
   passage of time are reported as provision for loan losses. Adopting these
   standards resulted in no initial increase to the allowance for loan losses.

   LOAN FEE INCOME - Fees related to lending activities are recognized as other
   income during the period the related services are performed.  Loan fee income
   for the years ended December 31, 1996 and 1995 was not material.

   PREMISES AND EQUIPMENT - Premises and equipment are recorded at cost and
   depreciated over their estimated useful lives. Depreciation expense is
   computed using the straight-line method over the estimated useful lives or
   contractual life of the related assets whichever is shorter. Estimated lives
   are 5 to 40 years for buildings and leasehold improvements and 3 to 25 years
   for equipment and fixtures. Gains or losses on disposition are reflected in
   operations. Expenditures for improvements are capitalized and ordinary
   maintenance and repairs are charged to operations as incurred.

   OTHER REAL ESTATE OWNED - Real estate acquired through foreclosures or in
   settlement of loans is recorded at the lower of fair market value minus
   estimated costs to sell or carrying value of the loan at the acquisition
   date.  Other real estate owned is included in other assets in the combined
   statement of financial condition.

   INCOME TAXES - Deferred income taxes related to the timing differences of
   recognizing income and expense for financial statement and income tax
   purposes are recorded on the liability method.

   NET INCOME PER COMMON SHARE - Net income per share is computed using the
   weighted average number of shares of common stock.

   NEWLY-ISSUED ACCOUNTING STANDARDS - In June 1996, the FASB issued SFAS No.
   125, Accounting for Transfers and Servicing of Financial Assets and
   Extinguishments of Liabilities to be effective for transfers and servicing of
   financial assets and extinguishments of liabilities occurring after December
   31, 1996. This statement provides consistent standards for distinguishing
   transfers of financial assets that are sales, from transfers that are secured
   borrowings. Management believes that

                                      F-7
<PAGE>
 
   the adoption of the provisions of this statement on FNBS's combined financial
   statements will not be material.

   In February 1997 the FASB issued SFAS No. 128, Earnings per Share, which will
   be adopted by FNBS in calendar 1997.  SFAS No. 128 requires companies to
   compute net income per share under two different methods, basic and diluted,
   and to disclose the methodology used for the calculation.  The adoption of
   SFAS No. 128 will not impact FNBS's results of operations or materially
   change the results of current earnings per share calculation.

   FUNB originates loans principally throughout central Kansas.  This region is
   predominately agricultural based, and its economic stability is dependent on
   the strength of the grain industry.  Although the subsidiaries have a
   diversified loan portfolio, a substantial portion of their debtors' ability
   to pay is dependent on the local economy.

   Substantially all of FNBS's commercial loans are secured by assignments of
   inventory, accounts receivable, buildings and equipment, or savings deposits;
   agricultural loans are secured by crops and

     crop equipment; consumer loans are generally secured by personal property
     or savings deposits; and all real estate loans are secured by land and

10.  REGULATORY RESTRICTIONS

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

     Quantitative measures established by regulation to ensure capital adequacy
     require FNBS and its subsidiary to maintain minimum amounts and ratios (set
     forth in the table below) of total and Tier I capital (as defined in the
     regulations) to risk-weighted assets (as defined), and of Tier I capital
     (as defined) to average assets (as defined). Management believes, as of
     December 31, 1996, that FNBS and its subsidiary meet all capital adequacy
     requirements to which they are subject.

     As of December 31, 1996 and December 31, 1995, the most recent regulatory
     notification categorized FUNB as well capitalized under the regulatory
     framework for prompt corrective action. To be categorized as well
     capitalized the Bank must maintain minimum total risk-based, Tier I risk-
     based and Tier I leverage ratios as set forth in the table. There are no
     conditions or events since that notification that management believes have
     changed FUNB's category.

     On a consolidated basis FNBS has met its minimum regulatory capital
     requirements, however, since these financial statements have been prepared
     on a combined basis, the capital ratios for FNBS have not been presented.

</TABLE>

     RESTRICTIONS ON DIVIDENDS - There are limited restrictions on the ability
     of FNBS to pay dividends from its retained earnings; however, under
     national banking law, FNBS's banking subsidiary may not, without approval
     of the Office of the Comptroller of the Currency (OCC), declare dividends
     payable to FNBS in excess of undivided profits, as defined by statute, less
     any required transfers to surplus. This statute also grants to the OCC the
     discretion to require any bank to suspend the payment of any and all
     dividends until any requirements that may have been made by the OCC, or any
     duly appointed examiner, shall have been complied with. At December 31,
     1996 and 1995, FUNB could have provided funds to FNBS of up to
     approximately $930,000 and $622,000, respectively, without further approval
     of regulatory authorities.

11.  EMPLOYEE BENEFIT PLANS

     FNBS has adopted a 401(k) savings and profit sharing plan (PSP). All full-
     time employees who have been continuously employed for one year are
     eligible to participate by having a percentage of their pay deferred under
     the PSP. FNBS, at its direction, may contribute a portion of the profits to
     the PSP. Participants will receive their share of those profits upon
     retirement or termination subject to the PSP's vesting schedule, as
     defined. The PSP provides deferred investment options to participants.
     FNBS's contribution to the PSP was $75,000 during 1996 and $70,000 during
     1995.

12.  RELATED PARTIES

     FNBS has entered into transactions with its directors, significant
     shareholders and their affiliates (related parties). The aggregate amount
     of loans to such related parties at December 1996 and 1995 was $55,000 and
     $100,000, respectively. During 1996, new loans to such related parties
     amounted to $45,000 with no repayments made.

13.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     Statement of Financial Accounting Standards No. 107, Disclosures About Fair
     Value of Financial Instruments (SFAS No. 107), requires disclosure of
     estimated fair value amounts of its financial 

                                      F-15
<PAGE>
 
    instruments. It is management's belief that the fair values presented below
    are reasonable based on the valuation techniques and data available as of
    December 31, 1996 and 1995, as more fully described in the following table.
    It should be noted that FNBS's operations are managed from a going concern
    basis and not a liquidation basis. As a result, the ultimate value realized
    for the financial instruments presented could be substantially different
    when actually recognized over time through the normal course of operations.
    Additionally, a substantial portion of FNBS's inherent value is FUNB's
    capitalization and franchise value. Neither of these components have been
    given consideration in the presentation of fair values which follow.

    The following presents the carrying value and fair value of the specified
    assets and liabilities held at December 31, 1996 and 1995. This information
    is presented solely for compliance with SFAS No. 107 and is subject to
    change over time based on a variety of factors.

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:

    CASH AND DUE FROM BANKS AND INTEREST-BEARING DEPOSITS IN OTHER BANKS - The
    book value of such financial instruments is assumed to approximate the fair
    value of such assets.

    SECURITIES AVAILABLE FOR SALE - Quoted market prices of dealer quotes were
    used to determine the fair value of investment securities.

    FEDERAL HOME LOAN BANK STOCK - The fair value of such stock approximates
    book value since FNBS is able to redeem this stock with the Federal Home
    Loan Bank at par value.

                                     F-16
<PAGE>
 
    LOANS - Loans were priced using the discounted cash flow method.  The
    discount rate used was the rate currently offered on similar products.

    NONINTEREST-BEARING DEPOSITS AND DEMAND DEPOSITS - The fair value was
    determined to approximate the carrying value (the amount payable on demand)
    since such deposits are immediately withdrawable.

    TIME DEPOSITS - For time certificates of deposit, the fair value was
    determined using the discounted cash flow method.  The discount rate was
    equal to the rate currently offered on similar products.

    SHORT-TERM BORROWINGS AND NOTE PAYABLE - These liabilities were valued using
    the discounted cash flow method. The discount rate was equal to rates
    currently offered on similar borrowings.

    COMMITMENTS ON LINE-OF-CREDIT AGREEMENTS AND STANDBY LETTERS OF CREDIT -
    These commitments are at market interest rates and approximate fair value.

15. COMMITMENTS AND CONTINGENCIES

    In the normal course of business, there are various commitments outstanding
    and contingent liabilities (such as guarantees and commitments to extend
    credit, etc.) that are not reflected in the accompanying financial
    statements. Commitments to extend credit are agreements to lend to a
    borrower as long as there is no violation of any condition established in
    the contract. Commitments generally have fixed expiration dates or other
    termination clauses and may require the 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.
    FNBS evaluates each borrower's creditworthiness on a case-by-case basis. The
    amount of the collateral obtained, if it is deemed necessary by FNBS upon
    extension of credit, is based on management's credit evaluation of the
    borrower. Collateral held varies but may include accounts receivable;
    inventory; property, plant, and equipment; and deposits.

    Standby letters of credit are conditional commitments issued by the
    subsidiary to guarantee the performance of a customer to a third party.
    Generally, standby letters of credit are expected to expire without being
    drawn upon. The credit risk involved in issuing letters of credit is
    essentially the same as that involved in extending loan facilities to
    borrowers. The subsidiary holds real or personal property as collateral
    supporting those commitments for which collateral is necessary.

    The amounts committed under these agreements represent the maximum potential
    loss of principal, if fully drawn and if the customer defaults. However, the
    actual credit risk varies depending on the creditworthiness of the customer
    and the value of the collateral held.

    Commitments outstanding at December 31 are summarized as follows:

16. PROPOSED MERGER

    On September 11, 1997, FNBS entered into a reorganization and merger
    agreement with Commercial Federal Corporation (Commercial). Under the terms
    of the merger agreement, and based upon Commercial's closing stock price at
    December 12, 1997 of $35.25 (adjusted for Commercial's three-for-two stock
    split distributed on December 15, 1997), Commercial will issue approximately
    992,857 shares (adjusted for Commercial's three-for-two stock split
    distributed on December 15, 1997) of its common stock with a total aggregate
    value of $34,998,000.

    Following the proposed acquisition, FNBS will be merged with and into
    Commercial Federal Bank, a wholly-owned subsidiary of Commercial. This
    pending merger transaction, which is subject to regulatory approvals, FNBS's
    shareholders' approvals and other conditions, is expected to be consummated
    before March 31, 1998.

   S-X. In the opinion of management, all adjustments (consisting of normal
   recurring accruals) considered necessary for fair presentation have been

                      REORGANIZATION AND MERGER AGREEMENT



          THIS REORGANIZATION AND MERGER AGREEMENT ("Agreement") is dated as of
September 11, 1997, by and among COMMERCIAL FEDERAL CORPORATION, a Nebraska
corporation ("Commercial"), and COMMERCIAL FEDERAL BANK, A FEDERAL SAVINGS BANK,
a Federally chartered savings bank and wholly-owned subsidiary of Commercial
("Bank"); and FIRST NATIONAL BANK SHARES, LTD, a Kansas corporation ("Company")
and FIRST UNITED NATIONAL BANK AND TRUST COMPANY, a national bank and wholly-
owned subsidiary of Company ("First United").

          WHEREAS, Commercial, a non-diversified, unitary savings and loan
holding company, with principal offices in Omaha, Nebraska, owns all of the
issued and outstanding capital stock of the Bank, with its principal offices in
Omaha, Nebraska;

          WHEREAS, Company, a registered bank holding company under the Bank
Holding Company Act of 1956, as amended (the "BHCA"), with principal offices in
Kansas City, Missouri, owns all of the issued and outstanding capital stock of
First United, with its principal offices in Great Bend, Kansas, and Missouri
Bank & Trust Company, Kansas City, Missouri ("Missouri Bank")as well as minority
equity interests in various other financial institutions and certain other
assets. (These minority equity interests in various other financial institutions
and those certain other assets are collectively referred to herein as the "Other
Assets" and are listed in Exhibit A hereto);

          WHEREAS, Commercial and Company desire to combine their respective
holding companies through an exchange so that the respective shareholders of
both Commercial and Company will have an equity ownership in the combined
holding company;

          WHEREAS, prior to consummation of the combination of Commercial and
Company it is intended that the majority stockholder of the Company will
purchase the Other Assets from the Company and that the Company will distribute
the stock of Missouri Bank to the Company's shareholders (the "Spin-Off")
pursuant to Section 355 of the Internal Revenue Code;

          WHEREAS, it is intended that to accomplish this result, the Company
will be acquired by means of a merger (the "Acquisition Merger or the "Merger")
of the Company with and into Commercial;

          WHEREAS, concurrently with the execution and delivery of this
Agreement, and as a condition and inducement to Commercial's willingness to
enter into this Agreement, J. Thomas Burcham, majority shareholder of Company
and its chairman of the board, has

                                       1
<PAGE>
 
entered into a voting agreement in the form attached hereto as Exhibit B (the
"Voting Agreements");

          WHEREAS, it is intended that for federal income tax purposes, the
Merger shall qualify as a reorganization within the meaning of Section 368 of
the Internal Revenue Code of 1986, as amended (the "Code") and this Agreement
shall constitute a plan of reorganization pursuant to Section 368 of the Code;
and

          WHEREAS, the Boards of Directors of Commercial and the Company (at
meetings duly called and held) have determined that this Agreement and the
transactions contemplated hereby are in the best interests of Commercial and the
Company, respectively, and their respective stockholders and have approved this
Agreement.

          NOW THEREFORE, in consideration of the premises and mutual promises
hereinafter set forth, and of other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto hereby
agree as follows:


                                   ARTICLE I
                        THE MERGER AND RELATED MATTERS

          1.1  Merger: Surviving Institution.  Subject to the terms and
               -----------------------------                           
conditions of this Agreement, and pursuant to the provisions of the Nebraska
Business Corporation Act ("NBCA") and the Kansas General Corporation Code
("KGCC"), at the Acquisition Merger Effective Time (as hereinafter defined), the
Company shall be merged with and into Commercial pursuant to the terms and
conditions set forth herein, and the separate corporate existence of the Company
shall cease.  The Acquisition Merger shall have the effects specified in the
NBCA and the KGCC, Section 1.4(e) hereof and the Acquisition Plan of Merger.
Upon the consummation of the Acquisition Merger, the separate corporate
existence of the Company shall cease and Commercial shall continue as the
surviving corporation following the Acquisition Merger (Commercial is sometimes
referred to herein in such capacity as the "Surviving Corporation").  Commercial
may at any time change the method of effecting the Merger if and to the extent
it deems such change to be desirable, provided, however, that no such change
                                      --------  -------                     
shall (A) alter or change the amount or kind of consideration to be issued to
holders of Company common stock as provided for in this Agreement, (B) adversely
affect the tax treatment to Company shareholders as a result of receiving the
consideration described in Section 1.3 herein or (C) materially impede or delay
the consummation of the transactions contemplated by this Agreement.

          1.2  Effective Time of the Merger.  As soon as practicable after each
               ----------------------------                                    
of the conditions set forth in Article V hereof have been satisfied or waived,
Commercial and the Company will file, or cause to be filed, articles or
certificates of merger with appropriate authorities of Nebraska and Kansas which
articles or

                                       2
<PAGE>
 
certificates of merger shall in each case be in the form required by and
executed in accordance with applicable provisions of law.  The Acquisition
Merger shall become effective at the time and date which is the later of the
time at which (i) the Nebraska articles of merger are filed with the appropriate
authorities of Nebraska and (ii) the Kansas certificate of merger is filed with
the appropriate authorities of Kansas (the "Acquisition Merger Effective Time"),
which shall be immediately following the Closing (as defined in Section 1.10
herein) and on the same day as the Closing if practicable.

          1.3  Conversion of Shares.
               -------------------- 

          (a)(i)  At the Acquisition Merger Effective Time, by virtue of the
Merger and without any action on the part of Commercial or Company or the
holders of shares of Commercial or Company common stock, each outstanding share
of Company common stock issued and outstanding at the Acquisition Merger
Effective Time (except for Dissenting Shares (as such term is defined in
paragraph (c) below) and shares referred to in subparagraph (a)(ii) of this
Section 1.3) shall be converted into and exchanged for the right to receive a
number of shares of Commercial common stock, $.01 par value per share (the
"Commercial common stock"), (such number of shares of Commercial common stock
the "Merger Consideration"), as follows:

          (A) If the Average NYSE Closing Price is equal to or less than $42.00,
but equal to or greater than $36.00, then the number of shares of Commercial
common stock to be received (the "Per Share Stock Consideration") shall equal
the quotient that results by dividing (x) the Per Share Purchase Price by (y)
the average NYSE Closing Price;

          (B) If the Average NYSE Closing Price is less than $36.00, then the
Per Share Stock Consideration shall equal that number of shares of Commercial
common stock which would have been issued as the Per Share Stock Consideration
if the Average NYSE Closing Price was $36.00; and

          (C) If the Average NYSE Closing Price is greater than $42.00 then the
Per Share Stock Consideration shall equal that number of shares of Commercial
common stock which would have been issued as the Per Share Stock Consideration
if the Average NYSE Closing Price was $42.00.

          (ii)  Any shares of Company common stock which are owned or held by
Company or any of its subsidiaries (except shares held in any 401(k) plan of the
Company or any of its subsidiaries or held in a fiduciary capacity) or by
Commercial or any of Commercial's subsidiaries (other than in a fiduciary
capacity) at the Acquisition Merger Effective Time shall cease to exist, and the
certificates for such shares shall as promptly as practicable be cancelled and
no shares of capital stock of Commercial shall be issued or exchanged therefor.

                                       3
<PAGE>
 
          (iii)  Each share of common stock of Commercial issued and outstanding
immediately prior to the Acquisition Merger Effective Time shall remain an
outstanding share of common stock of the Surviving Corporation.

          (iv) At the Acquisition Merger Effective Time, the holders of
certificates representing shares of Company common stock shall cease to have any
rights as stockholders of the Company, except the right to receive the Merger
Consideration as provided herein.

          (v)  If the holders of Commercial common stock shall have received or
shall have become entitled to receive, without payment therefor, during the
period commencing on the date hereof and ending with the Acquisition Merger
Effective Time, additional shares of common stock or other securities for their
stock by way of a stock split, stock dividend, reclassification, combination of
shares or similar corporate rearrangement ("Stock Adjustment"), then the amount
of Commercial common stock to be exchanged at the Acquisition Merger Effective
Time for Company common stock shall be proportionately adjusted to take into
account such Stock Adjustment.  In addition, the Average NYSE Closing Price, as
defined below, shall be proportionately adjusted to compensate for any such
Stock Adjustment.

          (b) Each share of Commercial common stock to be issued to the
Company's shareholders pursuant to this Section 1.3 shall include the
corresponding number of rights associated with the Commercial common stock
pursuant to the Rights Agreement dated as of December 19, 1988 by and between
Commercial and Manufacturers Hanover Trust Company, as Rights Agent ("Commercial
Rights Agreement").

          (c) Dissenting Shares.  Any shares of Company common stock held by a
              -----------------                                               
holder who dissents from the Acquisition Merger and becomes entitled to obtain
payment for the value of such shares of Company common stock pursuant to the
applicable provisions of the KGCC shall be herein called "Dissenting Shares."
Any Dissenting Shares shall not, after the Acquisition Merger Effective Time, be
entitled to vote for any purpose or receive any dividends or other distributions
and shall not be entitled to receive the Merger Consideration; provided,
however, that shares of Company common stock held by a dissenting stockholder
who subsequently withdraws a demand for payment, fails to comply fully with the
requirements of the KGCC, or otherwise fails to establish the right of such
stockholder to be paid the value of such stockholders' shares under the KGCC
shall be deemed to be converted into the right to receive the Merger
Consideration pursuant to the terms and conditions referred to above.

          (d) Definitions.  (i) The term "Average NYSE Closing Price" shall mean
              -----------                                                       
the arithmetic mean of the closing price per

                                       4
<PAGE>
 
share (carried to the fourth decimal point) of the Commercial common stock on
the New York Stock Exchange ("NYSE") for the twenty-fifth through the sixth
trading day, inclusive, immediately preceding the business day prior to the
later of (A) the date on which all requisite federal and state regulatory
approvals required to consummate the transactions contemplated by this
Agreement, including the Bank Merger, are obtained (and Commercial shall notify
the Company of the date when all such approvals are obtained), including for
this purpose the period of any requisite waiting periods in respect thereof, or
(B) the date the Company obtains the requisite approval of its shareholders as
contemplated in Section 1.7(a) herein (the "Determination Period").

          (ii)  The term "Per Share Purchase Price" shall be equal to the
quotient that results by dividing (i) the Aggregate Purchase Price by (ii)
15,317.65 plus any additional number of shares of Company common stock issued
after the date hereof in conformance with Section 4.2(b)(iii) herein.

          (iii)  The term "Aggregate Purchase Price" shall be equal to
$27,800,000, plus (A) the amount of cash held directly by the Company as of the
             ----                                                              
Acquisition Merger Effective Time as reflected on the Company's books and
records and (B) any amounts recorded as a receivable by the Company on its books
and records from First United and Missouri Bank and their subsidiaries pursuant
to the Company's income tax sharing agreements, with these banks dated February
15, 1997, April 24, 1995 and April 5, 1995, respectively, less (C) the amount of
                                                          ----                  
federal and state income tax liability (to the extent not paid prior to the
Closing) and net of receivables from the Internal Revenue Service attributable
to the taxable gain, if any, realized on the Spin-Off, the sale (if applicable)
of shares of Missouri Bank and the sale of the Other Assets as contemplated in
Section 1.12,(D) the amount of any dividends declared or paid by First United
since June 30, 1997, (E) the amount of any fee paid or payable by First United
or payable by the Company for the type of services referenced in Section 2.7
herein whether to Friedman, Billings Ramsey & Co., Inc. or otherwise and (F) all
other liabilities (including federal and state income tax liability of the
Company and Company Subsidiaries (to the extent not consolidated with the
Company)), together with any accrued but unpaid interest, of the Company as
reflected or required to be reflected under generally accepted accounting
principles on the Company's books and records as of the Closing (for purposes of
this subparagraph (iii), Exhibit 1.3(d) to the Agreement sets forth the amounts

Aggregate Purchase Price pursuant to clauses (A), (B),(D),(E) and (F) above
based upon contemplated contributions to capital and repayment of liabilities
intended to be effected on or prior to the Closing as contemplated herein.  Such
Exhibit shall be revised by the Company (to Commercial's reasonable
satisfaction) and delivered to Commercial as of the Closing). Such Aggregate

of Incorporation of the Surviving Corporation as the Surviving Corporation.

          (c) The bylaws of Commercial, together with all amendments thereto, if

          1.5  Authorization for Issuance of Commercial Common Stock; Exchange 
               --------------------------------------------------------------- 
               of Certificates.
               ---------------

          (a) Commercial shall reserve for issuance a sufficient number of
shares of its common stock for the purpose of issuing its shares to the
Company's shareholders in accordance with this Article I.  Immediately prior to
the Acquisition Merger Effective Time, Commercial shall make available for
exchange or conversion, by transferring to an exchange agent appointed by
Commercial (the "Exchange Agent") for the benefit of the holders of Company
common stock:  (i) such number of whole shares of Company common stock as shall
be issuable in connection with payment of the aggregate Merger Consideration,
and (ii) such funds as may be payable for cash in lieu of fractional shares of
Commercial common stock.

          (b) After the Acquisition Merger Effective Time, holders of
certificates theretofore evidencing outstanding shares of Company common stock
(other than Dissenting Shares and as provided in Section 1.3(a)), upon surrender
of such certificates to the Exchange Agent, shall be entitled to receive
certificates representing the number of whole shares of Commercial common stock
into which shares of Company common stock theretofore represented by the
certificates so surrendered shall have been converted, as well as cash payments
in lieu of fractional shares as provided in Section 1.6 hereof.  As soon as
practicable after the Acquisition Merger Effective Time, the Exchange Agent will
send a notice and transmittal form to each Company shareholder of record at the
Acquisition Merger Effective Time whose Company stock shall have been converted
into the Stock Consideration advising such shareholder of the effectiveness of
the Acquisition Merger and the procedure for surrendering to the Exchange Agent
outstanding certificates formerly evidencing Company common stock in exchange
for new certificates for Commercial common stock and cash in lieu of any
fractional interest.  Upon surrender, each certificate evidencing Company common
stock shall be cancelled.

          (c) Until surrendered as provided in this Section 1.5 hereof, each
outstanding certificate which, prior to the Acquisition Merger Effective Time,
represented Company common stock (other than Dissenting Shares and shares
cancelled at the Acquisition Merger Effective Time pursuant to Section 1.3(a)
hereof) will be deemed for all corporate purposes to evidence ownership of the
number of whole shares of Commercial common stock into which the shares of
Company common stock formerly represented thereby were converted and the right
to receive cash in lieu of any fractional interest.  However, until such
outstanding certificates formerly representing Company common stock are so
surrendered, no dividend or distribution payable to holders of record of
Commercial common stock shall be paid to any holder of such outstanding
certificates, but upon surrender of such outstanding certificates by such holder
there shall be paid to such holder the amount of any dividends or distribution,
without interest, theretofore paid with respect to such whole shares of
Commercial common stock, but not

                                       7
<PAGE>
 
paid to such holder, and which dividends or distribution had a record date
occurring on or subsequent to the Acquisition Merger Effective Time and cash
without interest in lieu of fractional shares pursuant to Section 1.6 hereof.
After the Acquisition Merger Effective Time, there shall be no further
registration of transfers on the records of the Company of outstanding
certificates formerly representing shares of Company common stock and, if a
certificate formerly representing such shares is presented to Commercial, it
shall be forwarded to the Exchange Agent for cancellation and exchange for
certificates representing shares of Commercial common stock and cash in lieu of
fractional shares as herein provided.

          (d) All shares of Commercial common stock and cash payable in lieu of
any fractional share issued and paid upon the surrender for exchange of Company
common stock in accordance with the above terms and conditions shall be deemed
to have been issued in full satisfaction of all rights pertaining to such shares
of Company common stock.

          (e) If any new certificate for Commercial common stock is to be issued
in the name other than that in which the certificate surrendered in exchange
thereof is registered, it shall be a condition of the issuance therefor that the
certificate surrendered in exchange shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such transfer pay to the
Exchange Agent any transfer or other taxes required by reason of the issuance of
a new certificate for shares of Commercial common stock in any name other than
that of the registered holder of the certificate surrendered, or establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
payable.

          (f) In the event any certificate for Company common stock shall have
been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for
such lost, stolen or destroyed certificate, upon the making of an affidavit of
that fact by the holder thereof, such shares of Commercial common stock and cash
payable in lieu of fractional shares, if any, as may be required pursuant
hereto; provided, however, that Commercial may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed certificate to deliver a bond in such sum as it may direct
as indemnity against any claim that may be made against Commercial, the Company,
the Exchange Agent or any other party with respect to the certificate alleged to
have been lost, stolen or destroyed.

          1.6  No Fractional Shares.  Notwithstanding any term or provision
               --------------------                                        
hereof, no fractional shares of Commercial common stock, and no certificates or
scrip therefor, or other evidence of ownership thereof, will be issued in
exchange for any shares of Company common stock; no dividend or distribution
with respect to Commercial common stock shall be payable on or with respect to
any

                                       8
<PAGE>
 
fractional share interests; and no such fractional share interest shall entitle
the owner thereof to vote or to any other rights of a shareholder of Commercial.
In lieu of such fractional share interest, any holder of Company common stock
who would otherwise be entitled to a fractional share of Commercial common stock
will, upon surrender of his certificate or certificates representing Company
common stock outstanding immediately prior to the Acquisition Merger Effective
Time, be paid the applicable cash value of such fractional share interest, which
shall be equal to the product of the fraction multiplied by the Average NYSE
Closing Price.  For the purposes of determining any such fractional share
interests, all shares of Commercial common stock received by the holders of the
Company common stock shall be combined so as to calculate the maximum number of
whole shares of Commercial common stock issuable to such Company shareholder in
the Acquisition Merger.

          1.7  Shareholders' Approvals.
               ----------------------- 

          (a) The Company shall obtain approval to the Merger of its
shareholders by consent or otherwise (the "Shareholders Approval").  The
affirmative approval of the holders of at least a majority of the issued and
outstanding shares of Company common stock entitled to vote shall be required
for such approval.

          (b) Commercial shall, at the earliest practicable date, obtain
approval of its shareholders of an amendment to its Articles of Incorporation to
increase the number of authorized shares of Commercial common stock to
50,000,000.

          1.8  Registration Statement; Prospectus/Proxy Statement.
               -------------------------------------------------- 

          (a) For the purposes (i) of registering the Commercial common stock to
be issued to holders of Company common stock in connection with the Merger with
the Securities and Exchange Commission ("SEC") and with applicable state
securities authorities, and (ii) of obtaining the Shareholders Approval, the
parties hereto shall cooperate in the preparation of an appropriate registration
statement (such registration statement, together with all and any amendments and
supplements thereto, being herein referred to as the "Registration Statement"),
including the prospectus/proxy statement (or information statement) satisfying
all applicable requirements of applicable state laws, and of the Securities Act
of 1933 (the "1933 Act") and the Securities Exchange Act of 1934 (the "1934
Act") and the rules and regulations thereunder (such prospectus/proxy statement
or information statement, together with any and all amendments or supplements
thereto, being herein referred to as the "Prospectus/Proxy Statement").

          (b) Commercial shall furnish such information concerning Commercial
and the Commercial Subsidiaries (as defined in Section 3.1 hereof) as is
necessary in order to cause the Prospectus/Proxy

                                       9
<PAGE>
 
Statement, insofar as it relates to such corporations, to comply with Section
1.8(a) hereof.  Commercial agrees promptly to advise the Company if at any time
prior to the Company Shareholders Approval any information provided by
Commercial in the Prospectus/Proxy Statement becomes incorrect or incomplete in
any material respect and to provide the information needed to correct such
inaccuracy or omission.  Commercial shall promptly file such supplemental
information as may be necessary in order to cause such Prospectus/Proxy
Statement, insofar as it relates to Commercial and the Commercial Subsidiaries,
to comply with Section 1.8(a).

          (c) The Company shall furnish Commercial with such information
concerning the Company and the Company Subsidiaries (as defined in Section 2.1
hereof) as is necessary in order to cause the Prospectus/Proxy Statement,
insofar as it relates to such corporations, to comply with Section 1.8(a)
hereof.  The Company agrees promptly to advise Commercial if at any time prior
to the Company Shareholders Approval any information provided by the Company in
the Prospectus/Proxy Statement becomes incorrect or incomplete in any material
respect and to provide Commercial with the information needed to correct such
inaccuracy or omission.  The Company shall furnish Commercial with such
supplemental information as may be necessary in order to cause the
Prospectus/Proxy Statement, insofar as it relates to the Company and the Company
Subsidiaries, to comply with Section 1.8(a).

          (d) Commercial shall file the Registration Statement with the SEC and
applicable state securities agencies.  Commercial shall use all reasonable
efforts to cause the Registration Statement to become effective under the 1933
Act and applicable state securities laws at the earliest practicable date.  The
Company authorizes Commercial to utilize in the Registration Statement the
information concerning the Company and the Company Subsidiaries provided to
Commercial for the purpose of inclusion in the Prospectus/Proxy Statement.  The
Company shall have the right to review and comment on the form of proxy
statement included in the Registration Statement as well as those portions
containing or describing information concerning the Company.  Commercial shall
advise Company promptly when the Registration Statement has become effective and
of any supplements or amendments thereto, and Commercial shall furnish Company
with copies of all such documents.  Prior to the Acquisition Merger Effective
Time or the termination of this Agreement, each party  shall consult with the
other  with respect to any material (other than the Prospectus/Proxy Statement)
that might constitute a "prospectus" relating to the Merger within the meaning
of the 1933 Act.

          (e) The Company shall consult with Commercial in order to determine
whether any directors, officers or shareholders of the  Company may be deemed to
be "affiliates" of Company ("affiliated persons") within the meaning of Rule 145
of the SEC promulgated under the 1933 Act.  All shares of Commercial common
stock issued to such Company affiliated persons in connection with the Merger

                                       10
<PAGE>
 
shall bear a legend upon the face thereof stating that transfer of the
securities is or may be restricted by the provisions of the 1933 Act and notice
shall be given to Commercial's transfer agent of such restriction, provided that
such legend shall be removed by delivery of a substitute certificate without
such legend if such Company affiliated person shall have delivered to Commercial
a copy of a letter from the staff of the SEC or an opinion of counsel, in form
and substance satisfactory to Commercial, to the effect that such legend is not
required for purposes of the 1933 Act, and, in any event, at any time after the
expiration of two years from the Acquisition Merger Effective Time unless, in
the opinion of the counsel for Commercial, such person was an "affiliate" of
Commercial within the meaning of Rule 145 within three months prior to the
expiration of such two year period.  So long as shares of such Commercial common
stock bear such legend, no transfer of such Commercial common stock shall be
allowed unless and until the transfer agent is provided with such information as
may reasonably be requested by counsel for Commercial to assure that such
transfer will not violate applicable provisions of the 1933 Act, or rules,
regulations or policies of the SEC.

          1.9  Cooperation; Regulatory Approvals.  The parties shall cooperate
               ---------------------------------                              
and use reasonable best efforts to complete the transactions contemplated
hereunder at the earliest practicable date.  Each party shall cause each of
their affiliates and subsidiaries to cooperate, in the preparation and
submission by them, as promptly as reasonably practicable, of such applications,
petitions, and other documents and materials as any of them may reasonably deem
necessary or desirable to the Board of Governors of the Federal Reserve System
("FRB"), the Office of the Comptroller of the Currency ("OCC"), the Federal
Deposit Insurance Corporation ("FDIC"), the Office of Thrift Supervision
("OTS"), Federal Trade Commission ("FTC"), Department of Justice ("DOJ"), SEC,
applicable Secretary of State, other regulatory authorities, holders of the
voting shares of common stock of the Company, and any other persons for the
purpose of obtaining any approvals or consents necessary to consummate the
transactions contemplated by this Agreement.  At the date hereof, none of the
parties is aware of any reason that the regulatory approvals required to be
obtained by it would not be obtained.  Without limiting the foregoing,
Commercial agrees to use its best efforts to cause all necessary applications to
be filed by November 1, 1997.

          1.10  Closing.  If (i) this Agreement has been duly approved by the
                -------                                                      
shareholders of the Company, and (ii) all relevant conditions of this Agreement
have been satisfied or waived, a closing (the "Closing") shall take place as
promptly as practicable thereafter at the principal office of Commercial at
which the parties hereto will exchange certificates, opinions, letters and other
documents as required hereby and will make the filings described in Section 1.2
hereof.  Such Closing will take place as soon as practicable as agreed by the
parties, provided, however, that the Closing shall be no more than thirty (30)
         --------  -------                                                    
days after the satisfaction or waiver of

                                       11
<PAGE>
 
all conditions and/or obligations contained in Article V of this Agreement.

          1.11  Closing of Transfer Books.  At the Acquisition Merger Effective
                -------------------------                                      
Time, the transfer books for Company common stock shall be closed, and no
transfer of shares of Company common stock shall thereafter be made on such
books.

          1.12  Sale of Other Assets.  Prior to December 31, 1997 (unless
                --------------------                                     
Commercial otherwise agrees in writing) the Company shall (i) effectuate the
Spin-Off and (ii) sell to J. Thomas Burcham, or his designee, the Other Assets,
for an aggregate purchase price (with respect to sale of the Other Assets) and
on such other terms and conditions as are reasonably satisfactory to Commercial
(which shall include indemnification from Mr. Burcham to Commercial against
claims or liabilities relating to Missouri Bank and the Other Assets, and for
any income tax liability either not reflected on the books of the Company (other
than with respect to First United) or arising from the Spin-Off or sale of the
Other Assets).  The parties recognize that prior to the Spin-Off the Company may
sell a portion of the Missouri Bank stock for cash at a price which reflects a
valuation of the fair market for 100 percent of the outstanding shares of
capital stock of Missouri Bank at not less than $7,773,000 unless otherwise
agreed to by Commercial.  Nothing contained herein shall be deemed to prohibit
the Company from effecting such sale, and for purposes hereof, the Company's tax
liability with respect to such sale shall be considered as a liability which
must be offset by cash on hand as of the Closing as provided in Section 4.17
herein.

                                   ARTICLE II
                   REPRESENTATIONS AND WARRANTIES OF COMPANY
                                AND FIRST UNITED

is duly organized, validly existing, and in good standing under the laws of the
respective jurisdiction under which it is organized, as set forth in Section 2.1

effect on the date of this Agreement, of Company and each Company Subsidiary.
The Company and each Company Subsidiary is qualified to do business as a foreign
corporation and is in good standing in each jurisdiction in which qualification

maximum extent permitted under applicable law.  The Company is duly registered

Company Subsidiary hereunder, Section 2.1 of Schedule I shall separately list
the name and location of each such Other Bank and the amount of equity
securities of such Other Bank owned by the Company expressed as both a number
and percentage of outstanding shares.

have been agreed to.  There are no options, convertible securities, warrants, or
other rights (preemptive or otherwise) to purchase or acquire any of the
Company's capital stock from the Company and no oral or written agreement,
contract, arrangement, understanding, plan or instrument of any kind

capital stock.

          2.3  Ownership of Subsidiaries.  Except as set forth in Section 2.3 of
               -------------------------                                        
Schedule I, all the outstanding shares of the capital stock of the Company
Subsidiaries are validly issued, fully paid, nonassessable and owned
beneficially and of record by the Company or a Company Subsidiary free and clear

convertible or exchangeable into such securities) of or profit participations in

          2.4  Financial Statements and Reports.
               -------------------------------- 

          For the past five years, the Company and the Company Subsidiaries have
timely filed all reports and documents required to be filed by them with the
FRB, OCC, the Missouri Department of Finance or the FDIC under various financial
institution laws and regulations except to the extent that all failures to so
file, in the aggregate, would not have a material adverse effect on the
business, financial condition or results of operations of the Company and the
Company Subsidiaries, taken as a whole; and all such documents, as finally
amended, complied in all material respects with applicable requirements of law
and, as of their respective date or the date as amended, did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  Except to the extent
stated therein or in Section 2.4 to Schedule I, all financial statements and
schedules included in the documents referred to in the preceding sentences (or
to be included in similar documents to be filed after the date hereof) (i) are
or will be (with respect to financial statements in respect of periods ending
after December 31, 1996) in accordance with the Company's books and records and
those of any of the Company Subsidiaries, and (ii) present (and in the case of
financial statements in respect of periods ending after December 31, 1996, will
present) fairly the consolidated balance sheet and the consolidated statements
of operations, stockholders' equity and cash flows of the Company and the
Company Subsidiaries as of the dates and for the period indicated in accordance
with generally accepted accounting principles applied on a basis consistent with
prior periods (except for the omission of notes to unaudited statements, year
end adjustments to interim results and changes to generally accepted accounting
principles).  The consolidated financial statements of the Company at December
31, 1996 and for

                                       14
<PAGE>
 
the three years then ended and the consolidated financial statements for all
periods thereafter up to the Closing reflect or will reflect, as the case may
be, all liabilities (whether accrued, absolute, contingent, unliquidated or
otherwise, whether due or to become due and regardless of when asserted) of the
Company and the Company Subsidiaries required to be reflected in such financial
statements according to generally accepted accounting principles and contain or
will contain adequate reserves for losses on loans and properties acquired in
settlement of loans, taxes and all other material accrued liabilities and for
all reasonably anticipated material losses, if any as of such date as required
by generally accepted accounting principles.  There exists no set of
circumstances that could reasonably be expected to result in any liability or
obligation material to  the Company or the Company Subsidiaries, taken as a
whole, except as disclosed in such consolidated financial statements at December
31, 1996 or for transactions effected or actions occurring or omitted to be
taken after December 31, 1996 (i) in the ordinary course of business, or (ii) as
permitted by this Agreement.

          2.5  Absence of Changes.
               ------------------ 

          (a) Since December 31, 1996, there has been no material adverse change
in the business, properties, financial condition, results of operations or
assets of the Company and the Company Subsidiaries, taken as a whole.  There is
no occurrence, event or development of any nature existing or, to the best
knowledge of the Company, threatened which may reasonably be expected to have a
material adverse effect upon the business, properties, financial condition,
operations or assets of Company or any Company Subsidiary.

          (b) Except as set forth in Section 2.5 of Schedule I,  since December
31, 1996, each of the Company and the Company Subsidiaries has owned and
operated their respective assets, properties and businesses in the ordinary

<PAGE>
 
those previously used for funding purposes, other than turnover assumptions, and
computed on the basis of a terminated plan), of any accrued benefits or other
obligations not listed elsewhere in this schedule, including without limitation,
premiums and contributions for which the Company or any Company Subsidiary is or
may be directly or indirectly liable to present or former employees, officers,
directors, and their beneficiaries, (iii) the net fair market value of the
assets held in any fund, policy, or other arrangement, and (iv) the amount of

Benefit Arrangement other than the amounts listed in Schedule 2.13 of Schedule
I.

          (b) Except as disclosed in Section 2.13 to Schedule I, all Employee
Plans and Benefit Arrangements which are in effect were in effect for
substantially all of calendar year 1996 and there has been no material amendment
thereof (other than amendments required to comply with applicable law) or no
material increase in the cost thereof or benefits payable thereunder on or after
January 1, 1996.

          (c) Each Employee Plan and Benefit Arrangement (i) has been
administered to date, and will be administered until the Closing, in accordance
with their terms and in compliance with the Code, ERISA, and all other
applicable rules and regulations, (ii) has, in a timely, accurate, and proper
manner, both filed all required government reports and made all required
employee communications, and (iii) between the date of this Agreement and the
Closing, will complete and file all such required reports.  No condition exists
that could constitute grounds for the termination of any Employee Plan under
Section 4042 of ERISA; no "prohibited transaction," as defined in Section 406 of
ERISA and Section 4975 of the Code, has occurred with respect to any Employee
Plan, or any other employee benefit plan maintained by Company or any Company
Subsidiary which is covered by Title I of ERISA, which could subject any person
to liability under Title I of ERISA or to the imposition of any tax under
Section 4975 of the Code nor has any Employee Plan subject to Part III of
Subtitle B of Title I of ERISA or Section 412 of the Code, or both, incurred any
"accumulated funding deficiency," as defined in Section 412 of the Code, whether
or not waived; nor has Company or any Company Subsidiary failed to make any
contribution or pay any amount due and owing as required by the terms of any
Employee Plan or Benefit Arrangement.  Neither Company nor any Company
Subsidiary has incurred or expects to incur, directly or indirectly, any
liability under Title IV of ERISA arising in connection with the termination of,
or a complete or partial withdrawal from, any plan covered or previously covered
by Title IV of ERISA which could constitute a liability of Commercial, or any of
its affiliates at or after the Acquisition Merger Effective Time.

proxy statement, schedule or report filed by Commercial or any Commercial
Subsidiary with the SEC or the OTS under the 1933 Act, or the 1934 Act, on the
date of effectiveness in the case of such registration statements, or on the
date of filing in the case of such reports or schedules, or on the date of
mailing in the case of such proxy statements, contained any untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  For the past five
years, Commercial and the Commercial Subsidiaries have timely filed all
documents required to be filed by them with the SEC, the OTS, or the FDIC under
various securities and financial institution laws and regulations, except to the
extent that all failures to so file, in the aggregate, would not have a material
adverse effect on the business, financial condition or results of operations of
Commercial and the Commercial Subsidiaries, taken as a whole; and all such
documents, as finally amended, complied in all material respects with applicable
requirements of law and, as of their respective date or the date as amended, did
not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.
Except to the extent stated therein, all financial statements and schedules
included in the documents referred to in the preceding sentences (or to be
included in similar documents to be filed after the date hereof) (i) are or will

with Commercial's books and records and those of any of its Subsidiaries, and
(ii) present (and in the case of financial statements in respect of periods
ending after December 31, 1996 will present) fairly the consolidated statement
of financial condition and the consolidated statements of operations,
stockholders' equity and cash flows of Commercial and its Subsidiaries as of the
dates and for the periods indicated in accordance with generally accepted

statements for all periods thereafter up to the Closing disclose or will
disclose, as the case may be, all liabilities (including contingent liabilities)
as of such date of Commercial and the Commercial Subsidiaries, other than
liabilities which are not, in the aggregate, material to Commercial and the
Commercial Subsidiaries, taken as a whole, and contain or will contain in the
opinion of management adequate reserves for losses on loans and properties
acquired in settlement of loans, taxes and all other material accrued
liabilities and for all reasonably anticipated material losses, if any as of
such date.  There exists no set of circumstances that could reasonably be
expected to result in any liability or obligation material to Commercial or the
Commercial Subsidiaries, taken as a whole, except as disclosed in such
consolidated financial statements at June 30, 1996, or for transactions effected
or actions occurring or omitted to be taken after June 30, 1996, (i) in the
ordinary course of business, or (ii) as permitted by this Agreement.

results of operations or assets of Commercial and the Commercial Subsidiaries,
taken as a whole.  Since March 31, 1997, there is no occurrence, event or
development of any nature existing or, to the best knowledge of Commercial,
threatened which may reasonably be expected to have a material adverse effect
upon the business, properties, financial condition, operations or assets of
Commercial or any Commercial Subsidiary.

additional Conforming Adjustments as requested by Commercial pursuant to this
Section 4.12.  No additional Conforming Adjustments taken by the Company and the

applicable published accounting rules and regulations thereunder, (iii) on the
basis of such procedures as are set forth therein but without performing an
audit in accordance with generally accepted auditing standards nothing has come

comply as to form in all material respects with the applicable accounting
requirements of the 1933 Act and 1934 Act and the published rules and
regulations thereunder; (B) said financial statements are not stated on a basis

corresponding period in the preceding year, in consolidated net income for
Company or any increase, as compared with the corresponding period in the
preceding year, in the provision for loan losses for Company, (iv) they have
performed certain specific procedures as a result of which they determined that
certain information of an accounting, financial or statistical nature included
in the Prospectus/Proxy Statement and requested by Commercial and agreed upon by
such accountants, which is expressed in dollars (or percentages obtained from
such dollar amounts) and obtained from accounting records which are subject to
the internal controls of the Company's accounting system or which has been
derived directly from such accounting records by analysis or computation is in
agreement with such records or computations made therefrom (excluding any
questions of legal interpretation), and (v) on the basis of such procedures as
are set forth in such letter, nothing came to their attention with respect to
the Company which would cause them to believe that the pro forma financial
statements had not been properly compiled on the pro forma basis described
therein.

          (d) No Material Adverse Change.  Between the date of this Agreement

change in the financial condition, business or results of operations of Company

subject, however, to the following three sentences.  If the Company elects to
exercise its termination right pursuant to this Section 5.4(e), it shall give
written notice to Commercial no later than the end of the aforementioned two day
period.  During the two business day period commencing with the business day
after its receipt of such notice, Commercial shall have the option to increase
the consideration to be received by the holders of Company common stock
hereunder, by adjusting the Exchange Ratio to equal the lesser of (I) the
quotient (calculated to four digits) obtained by dividing (A) the product of
$33.15 and the Exchange Ratio (as then in effect) by (B) the Average NYSE
Closing Price and (II) the quotient calculated to four digits) obtained by
dividing (A) the product of the Index Trigger and the Exchange Ratio (as then in
effect) and the Starting Price by (B) the Average NYSE Closing Price.  If
Commercial so elects within such two day period, it shall give written notice to
the Company no later than the end of the aforementioned two day period of such
election and the revised Exchange Ratio, whereupon no termination shall have
occurred pursuant to this Section 5.4(e) and this Agreement shall remain in
effect in accordance with its terms (except as the Exchange Ratio shall have
been so modified).

stock to shares of Company common stock to be exchanged as provided in Section

companies (as set forth on Exhibit 5.4(e) hereto) will be adjusted
proportionately for purposes of determining the Index Price.

          "Index Price,"  on a given date, means the weighted average of the

date of the first public announcement of entry into this Agreement or, if no

          If Commercial or any company belonging to the Index Group declares or
effects a stock dividend, reclassification, recapitalization, split-up,

               ---------------------------------------------------------------  
In the event of the termination and abandonment of this Agreement pursuant to

effect, except that (i) the provisions of Sections 2.7 and 3.7 (Brokers and
Finders), 4.8 (Publicity), 6.2 (Expenses) and 8.2 (Confidentiality) of this
Agreement shall survive any such termination and abandonment, and (ii) a

relieve the breaching party from liability for an uncured intentional and
willful breach of a representation, warranty, covenant, or agreement giving rise
to such termination.

          The representations, warranties and agreements of the parties set
forth in this Agreement shall survive the Acquisition Merger Effective Time, and
shall not be terminated and extinguished at the Acquisition Merger Effective
Time.

          6.2  Payment of Expenses.
               ------------------- 

          (a) Each of the parties hereto shall bear and pay all costs and
expenses incurred by it or on its behalf in connection with the transactions
contemplated hereunder.

          (b) Notwithstanding any provision in this Agreement to the contrary,
in order to induce Commercial to enter into this Agreement and as a means of
compensating Commercial for the substantial direct and indirect monetary, and
other costs incurred and to be incurred in connection with this Agreement and
the transactions contemplated hereby, the Company agrees that if this

Agreement is terminated in accordance with its terms and, prior to such
termination, a Termination Event, as defined in paragraph (c) below, shall have

Subsidiary; or

          (ii) the shareholders of the Company shall not have approved the
Acquisition Merger at the meeting held for that purpose or any adjournment
thereof (or through solicitation of consents) or such meeting shall not have
been held or shall have been cancelled prior to termination of this Agreement
(unless consents shall have been solicited and received in lieu of such meeting)
or no consents solicited or the Board of Directors of the Company shall have
recommended that the shareholders of the Company approve or accept any
Acquisition Transaction with any person other than Commercial or any affiliate
of Commercial.

          (iii)  After a proposal is made by any person other than Commercial or
any affiliate of Commercial to the Company or any of its shareholders to engage
in an Acquisition Transaction, the Company or any Company Subsidiary shall have
knowingly and intentionally breached any representation, warranty, agreement,
covenant or obligation contained in this Agreement, such breach would entitle

          7.1  Reports to the SEC.  Commercial shall continue to file all
               ------------------                                        
reports and data with the SEC necessary to permit the shareholders of Company
who may be deemed "underwriters" (within the meaning of Rule 145 under the 1933
Act) of Company common stock to sell the Company common stock received by them
in connection with the Merger pursuant to Rules 144 and 145(d) under such Act if
they would otherwise be so entitled.

Commercial or the Bank after the Acquisition Merger Effective Time shall be
eligible to participate in all benefit plans sponsored by Commercial or the Bank
to the same extent as other similarly situated Commercial or Bank employees,
with full credit for prior service with the Company or Company Subsidiaries for
purposes of vesting, eligibility for participation and co-payments and
deductibles.  Commercial shall honor all accrued vacation leave for the
employees of Company and the Company Subsidiaries following the Acquisition
Merger Effective Time.

          7.3  Income Tax Return.
               ----------------- 

          (a)  In determining the amount of federal and state income tax
liability attributable to the taxable gain, if any, realized on the Spin Off,
the sale (if applicable) of shares of Missouri Bank and the sale of the Other
Assets (as set forth in Section 1.12 herein), for purposes of determining the
Aggregate Purchase Price as contemplated in Section 1.3(d)(iii)(C) of this
Agreement, the parties shall prior to the Closing record a "good faith" estimate
of the amount of such liability.  For purposes of preparing this estimate, the
fair market value for 100 percent of the outstanding shares of Missouri Bank
capital stock shall not be  less than $7,773,000.

          (b) As soon as possible following the Acquisition Merger Effective
Time, Commercial shall cause to be prepared the final consolidated federal and
state income tax returns of the Company for the period from the end of the last
preceding fiscal income tax year of the Company to the Acquisition Merger
Effective Time.  The income and other tax items of Missouri Bank and the Other
Assets for all tax periods ending on or prior to, respectively, the dates of the
Spin Off and sale of the Other Assets shall be included in the consolidated
income tax return of the affiliated group of which the Company is the common
parent.  The Company agrees that its officers, including J. Thomas Burcham,
shall be reasonably available after the Acquisition Merger Effective Time to
consult with Commercial regarding such final income tax returns.  Commercial
agrees to provide Mr. Burcham with a copy of any such returns a reasonable time
prior to their filing with applicable taxing authorities and to consider in good
faith any comments he may have with respect to such returns.

          7.4  Continuation of Loan Participation Purchases by First United.
               ------------------------------------------------------------  
The parties recognize that both First United and Missouri Bank have benefitted
from the present practice of Missouri Bank selling overline loan participations
to First United.  Notwithstanding that any purchase of a loan participation by
First United or any successor thereto following the Merger must necessarily be
based on such participation meeting such financial institution's then credit
standards as determined in good faith, Commercial agrees that the current
practice of First United in purchasing loan participations offered by Missouri
Bank shall be continued by First United or any successor thereto but only for so
long as Commercial desires and only on such terms as are determined acceptable
by Commercial in its sole discretion (to be reasonably exercised).

         (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 address 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
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.A.
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 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 

                                       1

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 part, 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 stockholders'
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 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.A. 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.A. 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.
