  Dear Stockholder:

     You are invited to attend a special meeting of stockholders (the "Special
  Meeting") of Railroad Financial Corporation ("Railroad") to be held at 110
  South Main Street, 9th Floor, Wichita, Kansas, on Friday, September 22, 1995
  at 1:30 p.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 Railroad and its principal subsidiary, Railroad Savings Bank,
  fsb ("Railroad Savings") by Commercial Federal Corporation ("Commercial") and
  its principal subsidiary, Commercial Federal Bank, a Federal Savings Bank (the
  "Bank"), respectively, in accordance with a Reorganization and Merger
  Agreement by and among Commercial, the Bank, Railroad and Railroad Savings
  (the "Merger Agreement").  Pursuant to the Merger Agreement (1) Railroad will
  merge into Commercial and the outstanding shares of Railroad's common stock
  will be converted into shares of Commercial Common Stock as set forth below
  and in the accompanying Prospectus/Proxy Statement (the "Acquisition Merger")
  and (2) Railroad Savings will, following the Acquisition Merger, merge into
  the Bank (collectively, the "Merger"). Pursuant to the Merger Agreement, each
  share of Railroad Common Stock outstanding at the time of the Acquisition
  Merger will be converted into the right to receive a number of shares of
  Commercial Common Stock that have a value equal to $17.25 (such number of
  shares referred to as the "Exchange Ratio"), such value to be based upon the
  "Average Closing Price" of Commercial Common Stock (i.e., the arithmetic
  mean of the per share closing prices of Commercial Common Stock as reported on
  the New York Stock Exchange ("NYSE") for the twenty-fifth through the sixth
  trading day immediately preceding the effective time of the Acquisition
  Merger); provided, however, that (1) if such Average Closing Price is greater
  than $27.00 or less than $24.00, the Exchange Ratio shall be .6389 and .7188
  shares, respectively, of Commercial Common Stock, and (2) if the Average
  Closing Price of the Commercial Common Stock is less than $20.00 and the
  decline in the price of Commercial Common Stock during the period beginning on
  April 17, 1995 and ending on the last date utilized in the calculation of the
  Average Closing Price exceeds by more than 15% any decline in the weighted
  stock price of a designated group of financial institutions listed on the SNL
  Midwest Thrift Index during the same period, Railroad will have the right to
  terminate the Merger Agreement unless Commercial elects to adjust the Exchange
  Ratio to equal $14.38 divided by the Average Closing Price. Based on the
  closing price per share of Commercial Common Stock on the NYSE on   August 
  10, 1995, of $31.625, each share of Railroad Common Stock would be exchanged
  for .6389 shares of Commercial Common Stock. Such Exchange Ratio may 
  increase or decrease depending on the Average Closing Price of Commercial
  Common Stock. Cash will be paid in lieu of fractional shares. Following the
  Merger, Commercial will be the resulting holding company, and the Bank will be
  the resulting savings institution. Consummation of the Merger is conditioned
  upon, among other things, receipt of all required regulatory approvals and
  approval by Railroad's stockholders.     

     At the Special Meeting, stockholders of Railroad will consider and vote
  upon approval of the Acquisition Merger and the Merger Agreement. In
  addition, the stockholders of Railroad may be asked to approve adjournment of
  the Special Meeting if necessary to permit further solicitation of proxies in
  the event that there are not sufficient votes at the time of the Special
  Meeting to approve the Acquisition Merger and the Merger Agreement. The
  aggregate consideration to be received by Railroad's stockholders under the
  Merger Agreement was negotiated by your Board of Directors in light of various
  factors, including Railroad's recent operating results, current financial
  condition and future prospects. 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
<PAGE>
 
  Railroad and its stockholders.  Accordingly, your Board of Directors
  unanimously recommends that you vote FOR approval of the Acquisition Merger
  and the Merger Agreement and FOR adjournment of the Special Meeting, if
  necessary.

     Railroad's Board of Directors has received the opinion of its financial
  advisor, Piper Jaffray Inc., that the consideration to be received by holders
  of Railroad's common stock in the Acquisition Merger is fair from a financial
  point of view.

     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,

                                            [SIGNATURE]

                                            Robert D. Taylor
                                            Chairman of the Board, President and
                                            Chief Executive Officer

                                Proxy Statement
                      For Special Meeting of Stockholders
                        To Be Held on September 22, 1995
                    ----------------------------------------

       This Prospectus/Proxy Statement is being furnished to the holders of the
  common stock, par value $.10 per share, of Railroad Financial Corporation
  ("Railroad") ("Railroad Common Stock") in connection with the solicitation of
  proxies by Railroad's Board of Directors for use at a special meeting of
  stockholders (the "Special Meeting") to be held at 110 South Main Street, 9th
  Floor, Wichita, Kansas, on Friday, September 22, 1995 at 1:30 p.m., local
  time.

       The purposes of the Special Meeting and the matters to be acted upon are:
  (i) to consider and vote upon the proposed merger of Railroad into Commercial
  Federal Corporation ("Commercial"), with Commercial as the surviving
  corporation (the "Acquisition Merger"), in accordance with a Reorganization
  and Merger Agreement by and between Commercial; Commercial Federal Bank, a
  Federal Savings Bank (the "Bank"), the wholly-owned savings institution
  subsidiary of Commercial; Railroad; and Railroad Savings Bank, fsb ("Railroad
  Savings"), the wholly-owned savings institution subsidiary of Railroad, dated
  April 18, 1995 (the "Merger Agreement"), which sets forth the terms and
  conditions of the Acquisition Merger and also provides for the subsequent
  merger of Railroad Savings into the Bank; (ii) to consider and vote upon
  adjournment of the Special Meeting if necessary to permit further solicitation
  of proxies in the event that there are not sufficient votes at the time of the
  Special Meeting to approve the Acquisition Merger and the Merger Agreement;
  and (iii) 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 Railroad Common Stock
  outstanding at the effective time of the Acquisition Merger (the "Acquisition
  Merger Effective Time") will be converted into the right to receive a number
  of shares of Commercial common stock, par value $.01 per share ("Commercial
  Common Stock") that have a value equal to $17.25 (such number of shares
  referred to as the "Exchange Ratio"), such value to be based upon the "Average
  Closing Price" of Commercial Common Stock (i.e., the arithmetic mean of
  the per share closing prices of Commercial Common Stock as reported on the New
  York Stock Exchange ("NYSE") for the twenty-fifth through the sixth trading
  day immediately preceding the effective time of the Acquisition Merger (the
  "Determination Period")); provided, however, that (1) if such Average Closing
  Price of the Commercial Common Stock is greater than $27.00 or less than
  $24.00, the Exchange Ratio shall be .6389 and .7188 shares, respectively, of
  Commercial Common Stock, (2) if the Average Closing Price of the Commercial
  Common Stock is less than $20.00 and the decline in the price of Commercial
  Common Stock during the period beginning on April 17, 1995 and ending on the
  last date utilized in the calculation of the Average Closing Price exceeds by
  more than 15% any decline in the weighted price of a designated group of
  financial institutions listed on the SNL Midwest Thrift Index (the "Index
  Group") during the same period, Railroad will have the right to terminate the
  Merger Agreement unless Commercial exercises its option to adjust the Exchange
  Ratio to equal $14.38 divided by the Average Closing Price.     
<PAGE>
 
     
 Trading of the Commercial Common Stock on the NYSE commenced August 2, 1995.
 Prior to that date, the Commercial Common Stock was traded on the Nasdaq
 National Market. Any references herein to the closing price of the Commercial
 Common Stock for the period up to and including August 1, 1995 shall be to the
 closing price as reported on the Nasdaq National Market. Based on the closing
 price per share of Commercial Common Stock on the NYSE on August 10,
 1995, of $31.625, each share of Railroad Common Stock would be exchanged for
 .6389 shares of Commercial Common Stock. Such Exchange Ratio may increase or
 decrease depending on the Average Closing Price of Commercial Common Stock.
 Cash will be paid in lieu of fractional shares.      

       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 its common stock, par value $.01 per share, 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
  Railroad upon consummation of the Acquisition Merger.

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

  whose primary asset is the Bank.  The Bank is a consumer-oriented financial
  institution that emphasizes traditional savings and loan operations, including

  Railroad Financial Corporation and Railroad Savings Bank, fsb

       Railroad is the holding company of Railroad Savings, the second largest
  savings institution headquartered in Wichita, Kansas and the third largest
  savings institution headquartered in the State of Kansas. Railroad's principal
  business, which is conducted through Railroad Savings, is the acceptance of
  deposits from the general public and the origination, purchase, sale and
  servicing of mortgage loans for the purpose of constructing, financing or
  refinancing one- to four-family dwellings, and other residential and
  commercial real estate. In addition to its direct investment in mortgage
  loans, Railroad invests in mortgage-backed, money market, and other investment
  securities. Railroad serves deposit and loan customers through its 18 full-
  service branch offices and 71 agency offices in the State of Kansas and serves
  loan customers in California, Nevada, Colorado, Oklahoma and Missouri.
  Railroad Savings entered into an agreement to acquire seven additional Kansas
  branches with $90.7 million in deposits from First Bank, fsb. This transaction
  closed on June 23, 1995. As consideration for the assumption of the deposits
  and other obligations associated with the branches, Railroad Savings received
  a payment equal to the aggregate deposits at the branches reduced by an amount
  equal to the value of the assets transferred and by a deposit premium equal to
  3.13% of total deposits. The agency offices of Railroad Savings were reduced
  from 74 to 71 after the acquisition of these seven additional branches.

  Railroad Savings Bank, fsb" herein.

  The Merger

       General.  The Merger Agreement provides for the acquisition of Railroad
  by Commercial, and the subsequent merger of Railroad Savings into the Bank, as
  follows:  (i) Railroad will merge into Commercial, with Commercial as the
  surviving corporation, pursuant to which the outstanding shares of Railroad
  Common Stock will be converted into shares of Commercial Common Stock as set
  forth below under " -- Conversion of Railroad Common Stock" (the Acquisition
  Merger); and (ii) Railroad Savings will, following the Acquisition Merger,
  merge into the Bank, with the Bank as the surviving savings institution (the
  "Bank Merger") (collectively, the "Merger").  At the Acquisition Merger
  Effective Time, Railroad will have merged into Commercial.  Upon the
  consummation of the Bank Merger (the "Bank Merger Effective Time"), Railroad
  Savings 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.

       The Board of Directors of Railroad considered the Merger and the terms of
  the Merger Agreement, including the Exchange Ratio, in light of economic,
  financial, legal and market factors and concluded that the Merger is in the
  best interests of Railroad and its stockholders.   The Board of Directors
  believes that the Merger will afford Railroad's stockholders the benefit of,
  among other things, the greater potential for long term growth and will offer
  enhanced abilities to meet the needs of the communities served by Railroad
  Savings.

       The Board of Directors of Railroad believes that the Merger is in the
  best interests of Railroad and its stockholders and recommends that Railroad'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
  Railroad Board of Directors" herein and the Merger Agreement attached as Annex
  A hereto.

       Financial Advisors and Opinions of Financial Advisors.  The Board of
  Directors of Railroad has received written opinions of Piper Jaffray Inc.
  ("Piper Jaffray") that, as of the date of such opinions, based upon and
  subject to the assumptions, factors and limitations set forth therein, the
  consideration to be received by holders of Railroad Common Stock in the
  Acquisition Merger is fair from a financial point of view.  The Piper Jaffray
  opinion was updated and confirmed on August 9, 1995.  A copy of the Piper
  Jaffray opinion dated August 9, 1995, is attached as Annex B hereto, and the
  description set forth herein is qualified in its entirety by reference to this
  opinion.

       Commercial has retained Merrill Lynch & Co. ("Merrill Lynch") to render
  its opinion with respect to the fairness to Commercial of the Exchange Ratio
  negotiated by Commercial and Railroad.  Merrill Lynch rendered its oral
  opinion to Commercial's Board of Directors on April 18, 1995, which it
  subsequently confirmed in writing, that as of the date of such opinion, the
  Exchange Ratio was fair to Commercial from a financial point of view.  The
  opinion sets forth a description of the assumptions made and matters
  considered by Merrill Lynch and contains certain limitations and
  qualifications.  The Merrill Lynch opinion was updated and confirmed on August
  11, 1995.  A copy of the Merrill Lynch opinion is available for inspection
  and copying at the principal executive offices of Commercial during its
  regular business hours by any interested stockholder of Commercial or Railroad
  or his authorized representative.
      
       Conversion of Railroad Common Stock.  Pursuant to the Merger Agreement,
  each share of Railroad Common Stock outstanding at the Acquisition Merger
  Effective Time (other than shares owned or held by Commercial) will be
  converted into the right to receive a number of shares of Commercial Common
  Stock (the Exchange Ratio) that have a value equal to $17.25, such value to be
  based upon the Average Closing Price of Commercial Common Stock (i.e., the
  arithmetic mean of the per share closing prices of Commercial Common Stock as
  reported on the NYSE for the Determination Period); provided, however, that
  (1) if such Average Closing Price of the Commercial Common Stock is greater
  than $27.00 or less than $24.00, the Exchange Ratio shall be .6389 and .7188
  shares, respectively, of Commercial Common Stock, (2) if the Average Closing
  Price of the     

                                       4
<PAGE>
       
  Commercial Common Stock is less than $20.00 and the decline in the price of
  Commercial Common Stock during the period beginning on April 17, 1995 and
  ending on the last date utilized in the calculation of the Average Closing
  Price exceeds by more than 15% any decline in the weighted stock price of the
  Index Group during the same period, Railroad will have the right to terminate
  the Merger Agreement unless Commercial exercises its option to adjust the
  Exchange Ratio to equal $14.38 divided by the Average Closing Price. Based on
  the closing price per share of Commercial Common Stock on the NYSE on
  August 10, 1995, of $31.625, each share of Railroad Common Stock would be
  exchanged for .6389 shares of Commercial Common Stock. Such Exchange Ratio
  may increase or decrease depending on the Average Closing Price of Commercial
  Common Stock. Cash will be paid in lieu of fractional shares. Shares of
  Railroad Common Stock owned or held by Commercial or a subsidiary (other than
  in a fiduciary capacity) would be cancelled. For additional information, see
  "The Merger --Conversion of Railroad Common Stock" herein.     

       Treatment of Railroad Stock Options.  At the Acquisition Merger Effective
  Time, each outstanding option under Railroad's 1994 Stock Option and Incentive
  Plan, 1986 Stock Option and Incentive Plan and 1991 Director's Stock Option
  Plan (collectively, the "Railroad Option Plans") will continue outstanding as
  an option to purchase the number of shares of Commercial Common Stock that
  would have been received by the optionee in the Merger had the option been
  exercised in full (without regard to any limitations contained therein on
  exercise) for shares of Railroad Common Stock immediately prior to the
  Acquisition Merger.  Such options shall remain outstanding on the same terms
  and conditions under the relevant option as were applicable immediately prior
  to the Acquisition Merger Effective Time, except for appropriate pro rata
  adjustments as to the option price for shares of Commercial Common Stock
  substituted therefor so that the aggregate option exercise price of shares
  subject to an option immediately following the assumption and substitution
  shall be the same as the aggregate option exercise price for such shares
  immediately prior to such assumption and substitution. In addition, under the
  terms of Railroad's 1994 Stock Option and Incentive Plan, all options will
  become fully vested upon consummation of the Merger. For additional
  information, see "The Merger --Treatment of Railroad Stock Options" herein.

       Dissenters' Appraisal Rights.  Under Delaware law, stockholders of
  Railroad will not have any dissenters' rights of appraisal as a result of the
  matters to be voted upon at the Special Meeting.  See "The Merger -- No
  Dissenters' Appraisal Rights."

       Stock Option Agreement.  As a condition to Commercial's entry into the
  Merger Agreement, Railroad and Commercial entered into a  Stock Option
  Agreement dated April 18, 1995 (the "Stock Option Agreement"), pursuant to
  which Railroad granted to Commercial an option to purchase shares of
  authorized and unissued or treasury shares of Railroad Common Stock in an
  amount up to 13.0% of the outstanding shares of such stock upon or after the
  occurrence of a "purchase event" (as defined therein).  The exercise price is
  $11.875 per share payable in cash.  The Stock Option Agreement is intended to
  increase the likelihood that the Merger will be consummated in accordance with
  the terms of the Merger Agreement.  Consequently, certain aspects of the Stock
  Option Agreement may have the effect of discouraging persons who otherwise
  might be interested in acquiring all of or a significant interest in Railroad
  from considering or proposing such an acquisition, even if such persons were
  prepared to pay for the Railroad Common Stock a price in excess of that being
  paid by Commercial in the Merger.  For additional information, see "The Merger
  -- Stock Option Agreement" herein and the Stock Option Agreement, which is
  attached hereto as Annex C.

       Conditions to the Merger.  The obligations of Commercial and Railroad to
  effect the Merger are jointly subject to a number of conditions regarding,
  among other things, stockholder and regulatory approval of the Merger and
  receipt of an opinion with respect to the tax effects of the Merger.  The
  obligations of Commercial and the Bank to effect the Merger are subject to a
  number of additional conditions regarding, among other things, (i) receipt of
  a customary legal opinion from Railroad's legal counsel; (ii) receipt by
  Railroad and Railroad Savings of certain third party consents and approvals;
  (iii) receipt of a letter from Railroad's independent public accountants
  regarding certain financial information included in this Prospectus/Proxy
  Statement and other matters; (iv) the absence of material adverse changes in
  the financial condition, business or results of operations of Railroad and its
  subsidiaries; (v) the accuracy of Railroad's and Railroad Savings'
  representations and their performance of obligations and compliance with
  covenants and conditions under the Merger Agreement; (vi) receipt of a letter
  from Commercial's independent public accountants stating its opinion that the
  Merger should be accounted for by Commercial as a pooling of

                                       5
<PAGE>
 
  interests for financial statement purposes and that such accounting treatment
  is in accordance with generally accepted accounting principles; (vii) the
  receipt by Commercial of an updated written opinion from its financial advisor
  to the effect that the Exchange Ratio is fair to Commercial from a financial
  point of view; (viii) the receipt by Commercial of a Phase I Environmental
  Risk Report on certain properties owned by, and securing loans made by,
  Railroad and Railroad Savings; and (ix) the receipt of all required
  governmental approvals without the imposition of any conditions which
  Commercial and the Bank determine to be unduly burdensome on the conduct of
  the business of Commercial or the Bank (including the receipt of written
  confirmation from the Office of Thrift Supervision ("OTS") that the Bank, as
  the surviving institution of the Bank Merger, is lawfully authorized (and such
  authorization shall be subject to no time or other restriction not in effect
  as of the date of the Merger Agreement) to operate, maintain and replace the
  Railroad Savings agency offices to the same extent as Railroad Savings
  currently operates, maintains and replaces such agency offices).  The
  obligations of Railroad and Railroad Savings to effect the Acquisition Merger
  and the transactions contemplated in the Merger Agreement are subject to a
  number of additional conditions regarding, among other things, (i) receipt of
  a customary legal opinion from Commercial's legal counsel; (ii) the accuracy
  of Commercial's and the Bank's representations and warranties and their
  performance of obligations and compliance with covenants and conditions under
  the Merger Agreement; (iii) the receipt by Railroad of an updated written
  opinion from its financial advisor to the effect that the consideration to be
  received by Railroad shareholders in the Acquisition Merger is fair from a
  financial point of view; and (iv) receipt by Commercial and the Bank of
  certain third party consents and approvals.  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 OTS.  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.  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 Railroad stockholders, in a number of circumstances, including, by
  mutual consent of the parties; at the election of either party, if the closing
  of the Merger shall not have occurred on or before March 31, 1996; 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; by
  Railroad at any time during the two business days commencing on the business
  day immediately following the end of the Determination Period, if the Average
  Closing Price of Commercial Common Stock is less than $20.00 and the
  decline in the price of Commercial Common Stock during the period beginning on
  April 17, 1995 and ending on the last date utilized in the calculation of the
  Average NMS Closing Price exceeds by more than 15% any decline in the weighted
  stock price of the Index Group during the same period; provided, however, that
  Railroad shall not be entitled to terminate the Merger Agreement on this basis
  if Commercial exercises its option to adjust the Exchange Ratio so that it
  equals the number obtained by dividing $14.38 by the Average Closing Price
  of Commercial Common Stock.  For additional information, see "The Merger --
  Amendment or Termination of the Merger Agreement" herein.      

       Interests of Certain Persons in the Merger.  Shares of Railroad Common
  Stock held by directors, officers and employees of Railroad will be converted
  into Commercial Common Stock under the Merger Agreement on the same basis as
  shares held by other Railroad stockholders.  Directors, officers and employees
  of Railroad who hold unexercised options to purchase Railroad Common Stock
  under the Railroad Option Plans at the Acquisition Merger Effective Time will
  have their stock options converted into options to purchase Commercial Common
  Stock.

       At August 9, 1995, officers and directors of Railroad held options to
  purchase 120,509 shares of Railroad Common Stock at prices ranging between
  $2.43 and $9.63 per share.  The weighted average price of such options was
  approximately $7.12 per share.

       In addition, Commercial has agreed to provide indemnification for a
  period of six years to Railroad's employees, agents, directors or officers
  arising by virtue of Railroad's certificate of incorporation or bylaws in the
  form in effect at the date of the Merger Agreement or arising by operation of
  law.

       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.

       Federal Income Tax Consequences.   Commercial and Railroad will rely upon
  an opinion of Deloitte & Touche LLP, tax advisor to Commercial, to the effect
  that, among other things, (i) no gain or loss will be recognized by
  Commercial, the Bank, Railroad or Railroad Savings by reason of the
  Acquisition Merger or the Bank Merger; (ii) no gain or loss will be recognized
  by Railroad stockholders (except in connection with the receipt of cash in
  lieu of fractional share interests in Commercial Common Stock) upon the
  exchange of Railroad Common Stock for Commercial Common Stock in the
  Acquisition Merger; and (iii) cash received by Railroad stockholders in lieu
  of fractional share interests in Commercial Common Stock will be treated as
  having been received as distributions in full payment in exchange for the
  fractional share interests in Commercial Common Stock which they would
  otherwise be entitled to receive and will qualify as capital gain or loss if
  the stockholders held the Railroad Common Stock as a capital asset at the
  Acquisition Merger Effective Time.  For additional information, see "The
  Merger -- Federal Income Tax Consequences" herein.

       Accounting Treatment.  The Merger is expected to be accounted for as a
  pooling of interests.  The consummation of the Merger is conditioned upon the
  receipt by Commercial from the independent public accountants for Commercial,
  of a letter dated the Acquisition Merger Effective Time stating their opinion
  that the Merger should be accounted for by Commercial as a pooling of
  interests for financial statement purposes and that such accounting treatment
  is in accordance with generally accepted accounting principles.  For
  additional information, see "The Merger -- Accounting Treatment" herein.

  Comparison of Stockholder Rights

       Upon consummation of the Merger, holders of Railroad Common Stock, whose
  rights are presently governed by Delaware law and Railroad's certificate of
  incorporation and bylaws, and indirectly Railroad Savings' charter and bylaws,
  will become stockholders of Commercial, a Nebraska corporation.  Accordingly,
  their rights will be governed by the Nebraska Business Corporation Act and the
  articles of incorporation and bylaws of Commercial and indirectly by the
  Bank's charter and bylaws.  Certain differences arise from the change in
  governing law, as well as from differences between the certificate of
  incorporation and bylaws of Railroad and the articles of incorporation and
  bylaws of Commercial and between the charter and bylaws of Railroad Savings
  and the Bank, including, among other things, the number of authorized shares
  of capital stock, the payment of dividends, 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
  meetings of stockholders, limitations on acquisitions of capital stock,
  approval requirements for mergers, consolidations, sale of substantially all
  assets and dissolution, rights of stockholders to dissent, limitations on
  directors' liability and amendment of corporate governing documents.  In
  addition, Commercial has in effect a shareholder rights plan, while Railroad
  has not adopted any similar plan.  For additional information, see "Comparison
  of Stockholder Rights" herein.

  Adjournment of Special Meeting

       In the event that there are not sufficient votes to approve the
  Acquisition Merger and the Merger Agreement at the time of the Special
  Meeting, stockholders of Railroad will consider and vote upon a proposal to
  adjourn the Special Meeting for the solicitation of additional votes in favor
  of the Acquisition Merger and the Merger Agreement.  A majority of the shares
  represented and voting at the Special Meeting is required in order to approve
  any such adjournment.  Railroad's Board of Directors unanimously recommends
  that stockholders vote FOR the proposal to adjourn the Special Meeting if
  necessary to permit further solicitation of proxies.

       For additional information, see "Adjournment of Special Meeting" herein.

                   INFORMATION CONCERNING THE SPECIAL MEETING

  General

       This Prospectus/Proxy Statement is being furnished to the stockholders of
  Railroad as part of the solicitation of proxies by its Board of Directors from
  holders of the outstanding shares of Railroad Common Stock for use at the
  Special Meeting to be held on September 22, 1995, and any adjournments
  thereof.  This Prospectus/Proxy Statement, and the accompanying proxy card,
  are first being mailed to stockholders of Railroad on or about August 15,
  1995.

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

       In addition to approval of the Acquisition Merger and the Merger
  Agreement, the stockholders of Railroad may be asked to approve a proposal to
  adjourn the Special Meeting if necessary to permit further solicitation of
  proxies in the event that there are not sufficient votes at the time of the
  Special Meeting to approve the Acquisition Merger and the Merger Agreement.

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

    
RECENT EVENTS

       Deposit Insurance Premiums.  The Bank's and Railroad Savings' savings
deposits are insured by the Savings Association Insurance Fund ("SAIF"), which
is administered by the Federal Deposit Insurance Corporation ("FDIC").  The
assessment rate currently ranges from 0.23% of deposits for well capitalized
institutions to 0.31% of deposits for undercapitalized institutions.      
    
       The FDIC also administers the Bank Insurance Fund ("BIF"), which has the
same designated reserve ratio as the SAIF. On August 8, 1995, the FDIC adopted
an amendment to the BIF risk-based assessment schedule which lowered the
deposit insurance assessment rate for most commercial banks and other depository
institutions with deposits insured by the BIF to a range of from 0.31% of
insured deposits for undercapitalized BIF-insured institutions to 0.04% of
deposits for well-capitalized institutions, which constitute over 90% of 
BIF-insured institutions. The FDIC amendment becomes effective September 30, 
1995. The Amendment creates a substantial disparity in the deposit insurance 
premiums paid by BIF and SAIF members and could place SAIF-insured savings
institutions at a significant competitive disadvantage to BIF-insured
institutions.     
    
       A number of proposals are being considered to recapitalize the SAIF in
order to eliminate the premium disparity. One proposal being considered by the
Treasury Department, the FDIC and the Congress provides for a one time
assessment of from .85% to .90% of insured deposits to be imposed on all SAIF-
insured deposits held as of March 31, 1995. Under this proposal, the BIF and
SAIF would be merged into one fund as soon as practicable after they both reach
their designated reserve ratios, but no later than January 1, 1998. It is
unknown whether this particular proposal or any other proposal will be
implemented or that premiums for either BIF or SAIF members will be adjusted in
the future by the FDIC or by legislative action. If a special assessment as
described above were to be required, it would result, on a pro forma basis as of
March 31, 1995, in a one-time charge to Commercial of up to approximately $20.4
million (assuming such charge would be tax deductible), which would have the
effect of reducing Commercial's tangible capital to $273.7 million, or 4.75% of
adjusted total assets, core capital to $296.4 million, or 5.12% of adjusted
total assets, and risk-based capital to $325.2 million, or 12.72% of risk-
weighted assets. Similarly, such an assessment would result, on a pro forma
basis as of March 31, 1995, in a one-time charge to Railroad Savings of up to
approximately $1.8 million (assuming such charge would be tax deductible), which
would have the effect of reducing Railroad Savings' tangible and core capital to
$34.8 million, or 6.10% of adjusted total assets, and risk-based capital to
$36.8 million, or 11.94% of risk-weighted assets.

       If such a special assessment were required and the SAIF as a result was
fully recapitalized, it could have the effect of reducing Commercial's and
Railroad's deposit insurance premiums to the SAIF, thereby increasing net income
in future periods.
    
       Pending Sale of Mortgage Banking Operations.  On August 4, 1995, Railroad
Savings announced that it had entered into an agreement to sell its California
mortgage banking operations and its wholesale lending operations in Las Vegas,
Nevada to CUB Funding Corporation, a subsidiary of Republic Bancorp, Inc.  Under
the terms of the agreement, Railroad Savings is retaining the construction and
retail loan production operations in Las Vegas, Nevada.  The terms of the
agreement have been consented to by Commercial.  It is anticipated that the 
sale will close on August 15, 1995.     
    
  Recent Operating Results.      
    
  Commercial. For its fiscal year ended June 30, 1995 Commerical reported net 
  ----------
income of $27.5 million, or $2.11 per share, compared to net income of $158,000,
or $.01 per share, for the fiscal year ended June 30, 1994. The results for 
fiscal year 1995 include the pre-tax accelerated amortization of goodwill 
totaling $21.4 million which was recorded during the six months ended December 
31, 1994; and for the fiscal year 1994 the results include a pre-tax valuation 
adjustment to intangible assets totaling $52.7 million, as well as the 
cumulative effects of changes in accounting principles totaling $5.8 million, or
$.45 per share. Net income for the three months ended June 30, 1995 was $12.3 
million, or $.94 per share, compared to a net loss for the three months ended 
June 30, 1994, of $32.8 million, or a loss of $2.54 per share, which includes 
the aforementioned valuation adjustment. At June 30, 1995 Commercial's total 
assets were $6.0 billion.      
    
   Railroad. For the six months ended June 30, 1995, Railroad reported net 
   --------
income of $1,954,000, or $.90 per share, compared to net income of $185,000, or 
$.08 per share, for the six months ended June 30, 1994. Net income for the three
months ended June 30, 1995 was $448,000, or $.20 per share, compared to a net 
loss for the three months ended June 30, 1994 of $97,000, or $.04 per share. 
Increases in net income for the three and six months ended June 30, 1995 
compared to the three and six months ended June 30, 1994, are primarily due to 
net increases in net interest income totaling $728,000 and $1.1 million, 
respectively, net increases in gains on sale of loans and loan servicing 
totaling $568,000 and $354,000, respectively, and for the year-to-date results, 
a pre-tax gain of $1.2 million on the sale of an apartment and assisted care
facility. These increases in net income were partially offset by increases in
the provision for income taxes totaling $382,000 and $1.2 million, respectively.
    
    
   Further information regarding Railroad's operating results for the three and 
six months ended June 30, 1995 is included in Railroad's Quarterly Report on 
Form 10-Q for the quarter ended June 30, 1995, which is furnished herewith. 
     

  Solicitation, Voting and Revocability of Proxies
      
       The Board of Directors of Railroad has fixed the close of business on
  August 9, 1995 as the record date for the determination of the Railroad
  stockholders entitled to notice of and to vote at the Special Meeting.
  Accordingly, only holders of record of shares of Railroad 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 1,205 holders of record of the 2,130,572 shares of Railroad
  Common Stock then outstanding.  The presence, in person or by proxy, of a
  majority of the total number of outstanding shares of Railroad 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 outstanding
  shares of Railroad Common Stock is required to approve the Acquisition Merger
  and the Merger Agreement. The affirmative vote of a majority of the shares
  represented and voting at the Special Meeting is required to approve an
  adjournment of the Special Meeting. It is expected that substantially all of
  the 651,969 shares, or 30.6%, of outstanding Railroad Common Stock (excluding
  shares subject to stock options) beneficially owned by directors and officers
  of Railroad and their affiliates at August 9, 1995 will be voted for approval
  of the Acquisition Merger and the Merger Agreement.     
      
       If the accompanying proxy card is properly executed and returned to
  Railroad 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 and for the proposal to adjourn the Special
  Meeting if necessary to permit further solicitation of proxies.  Except for
  procedural matters incident to the conduct of the Special Meeting, the Board
  of Directors of Railroad 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 Railroad proxy will vote the shares represented by
  such proxy on such matters as determined by a majority of Railroad'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 that proposal.     

       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 Railroad at its headquarters address or by
  attending the Special Meeting and voting in person.

                                      14
<PAGE>
 
       The cost of soliciting proxies for the Special Meeting will be borne by
  Railroad.  In addition to use of the postal system, proxies may be solicited
  personally or by telephone or telegraph by directors, officers and employees
  of Railroad, who will not be specially compensated for such activities.
  Railroad will also request persons, firms and companies holding shares in
  their names or in the name of their nominees, which are beneficially owned by
  others, to send proxy materials to and obtain proxies from such beneficial
  owners and will reimburse such holders for their reasonable expenses incurred
  in that connection.

                       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.  The Bank is a consumer-oriented financial
  institution that emphasizes traditional savings and loan operations, including
  single-family residential real estate lending, retail deposit activities and
  mortgage banking.  The Bank conducts loan origination activities through its
  71 branch office network, loan offices of its wholly-owned mortgage banking
  subsidiary and a nationwide correspondent network consisting of approximately
  400 loan originators.  The Bank also provides insurance and securities
  brokerage and other retail financial services.

       At March 31, 1995, Commercial had assets of $5.8 billion and
  stockholders' equity of $296.7 million and through the Bank operated 68 branch
  offices.  In the period from October 1993 through April 1995, Commercial
  completed the acquisition of four financial institutions, adding 23 branch
  offices to its four-state retail network.  The Bank was the largest 
  depository institution headquartered in Nebraska as of March 31, 1995 and, 
  based upon total assets at that date, Commercial was the 17th largest 
  publicly held thrift institution holding company in the United States.  As 
  of July 17, 1995, the Bank operated 72 branches located as follows: 30 
  offices in Nebraska, 20 offices in greater metropolitan Denver, Colorado, 
  17 offices in Oklahoma and five offices in Kansas.

       Commercial will seek to continue its growth through expansion of the
  Bank's operations in its market areas, and may seek to enter markets in other
  adjoining states.  The Bank will also seek to expand its operations both
  through competition for market share within its market areas and through
  mergers with and acquisitions of other selected financial institutions.

       The Bank is a member of the Federal Home Loan Bank System and the Federal
  Home Loan Bank of Topeka, and its deposits are insured up to prescribed limits
  by the Federal Deposit Insurance Corporation ("FDIC").  The Bank is subject to
  comprehensive examination, supervision and regulation by the OTS and the FDIC.

       For additional information regarding the Bank, see Commercial's Annual
  Report on Form 10-K for the fiscal year ended June 30, 1994 and Quarterly
  Reports on Form 10-Q for the quarters ended September 30, 1994, December 31,
  1994 and March 31, 1995, which are incorporated by reference herein.

         RAILROAD FINANCIAL CORPORATION AND RAILROAD SAVINGS BANK, fsb

       Railroad is the holding company of Railroad Savings, the second largest
  savings institution headquartered in Wichita, Kansas and the third largest
  savings institution headquartered in the State of Kansas.  Railroad's
  principal business, which is conducted through Railroad Savings, is the
  acceptance of deposits from the general public and the origination, purchase,
  sale and servicing of mortgage loans for the purpose of constructing,
  financing or refinancing one- to four-family dwellings, and other residential
  and commercial real estate.  In addition to its direct investment in mortgage
  loans, Railroad invests in mortgage-backed, money market, and other investment
  securities.  Railroad serves deposit and loan customers through its 18 full-
  service branch offices and 71 agency offices in the State of Kansas and serves
  loan customers in California, Nevada, Colorado, Oklahoma and Missouri.

       Railroad's agency offices were established by independent contractor
  arrangements with agents along rail lines, providing deposits and lending
  services to remote communities.  When Railroad Savings converted from a state
  chartered to a federally chartered savings institution in 1989, it was granted
  a permanent exemption from the

                                      15
<PAGE>
 
  prohibitions applicable to federal savings institutions on the receipt of
  deposits by agents.  The exemption allows Railroad Savings to maintain and
  replace agency offices in communities already served.  Railroad Savings'
  agents are established by independent contractor agreements with local
  insurance agents, real estate brokers and the principals of abstract and title
  companies who accept deposits and loan applications from their own offices.
  Agency offices accounted for approximately 61% of Railroad's deposits at
  December 31, 1994 and approximately $36.7 million of Kansas loan originations
  during the year ended December 31, 1994.

       Railroad's income from the traditional financial services provided in
  Kansas through Railroad Savings' offices and agencies have been augmented
  during the past six years by the mortgage banking operations conducted
  primarily in Kansas and California. During 1994, Railroad consolidated the
  operations of its mortgage banking subsidiaries into Railroad Savings and
  opened additional construction loan production offices in Kansas, Missouri,
  Oklahoma and Nevada. Railroad has also sought to expand retail banking
  operations by opening additional branches. On January 31, 1995, Railroad
  Savings entered into an agreement to acquire seven additional Kansas branches
  with $90.7 million in deposits from First Bank, fsb. This transaction
  closed June 23, 1995. As consideration for the assumption of the deposits and
  other obligations associated with the branches, Railroad Savings received a
  payment equal to the aggregate deposits at the branches reduced by an amount
  equal to the value of the assets transferred and by a deposit premium equal to
  3.13% of total deposits. The agency offices of Railroad Savings were
  reduced from 74 to 71 after the acquisition of these seven additional 
  branches.

       For additional information regarding Railroad, including its consolidated
  financial statements and related notes as of December 31, 1994, see Railroad's
  Annual Report on Form 10-K for the year ended December 31, 1994, which is
  incorporated by reference herein, as well as its 1994 Annual Report to
  Stockholders and Quarterly Reports on Form 10-Q for the quarters ended March
  31, 1995, and June 30, 1995, which are incorporated by reference herein and 
  delivered herewith.

                                   THE MERGER
    (Proposal 1 -- Approval of the Acquisition Merger and Merger Agreement)

       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 Railroad by
  Commercial, and the subsequent merger of Railroad Savings into the Bank, as
  follows:  (i) Railroad will merge into Commercial, with Commercial as the
  surviving corporation, pursuant to which the outstanding shares of Railroad's
  common stock would be converted into shares of Commercial Common Stock as set
  forth below (the Acquisition Merger); and (ii) Railroad Savings 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), Railroad will have
  merged into Commercial.  Upon the consummation of the Bank Merger (the Bank
  Merger Effective Time), Railroad Savings 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.

       Stockholders of Railroad are being asked to approve the Merger Agreement
  and the Acquisition Merger.  The affirmative vote of at least a majority of
  the outstanding Railroad Common Stock is required for Railroad's stockholders
  to approve the Merger Agreement and the Acquisition Merger.

  Background of the Merger

       The Board of Directors of Railroad has periodically evaluated Railroad's
  corporate strategy in view of its capital position and market conditions,
  including the economic and regulatory environment, the potential disparity
  between thrifts and banks in deposit insurance premiums and the need to
  refinance the Savings Association Insurance Fund, the consolidation process in
  the depository institution industry, and the sharp increase in the number of
  acquisitions of thrifts including the prices paid in such acquisitions.

       Over the past four years, there has been considerable consolidation in
  the financial services industry, and Railroad has considered making several
  possible acquisitions. Management and the Board of Directors of Railroad have
  also maintained contacts with certain other financial institutions to assess
  the viability of potential acquisitions or affiliations. Although continuing
  to pursue a plan of remaining independent and growing the retail banking and
  mortgage banking franchise, the Board of Directors of Railroad resolved to
  consider any bona fide expressions of interest from interested parties that
  contacted Railroad.

       At the beginning of 1993, Railroad Savings' capital position had improved
  dramatically and Railroad embarked on a growth plan.  This plan included
  opening new offices in the State of Kansas and other states.  It also included
  increasing assets.  In the spring of 1993, Railroad acquired Ute City Mortgage
  Company and its operations in Aspen and Telluride, Colorado.  At this time,
  Railroad began expanding in other Colorado markets, including the rapidly
  growing Denver construction loan market.  In late 1993, Railroad Savings
  opened a loan origination office in Lawrence, Kansas.

       In May 1993, the Board of Directors of Railroad began the process of
  inquiring into the possible value of Railroad in light of merger activities at
  that time, including recent sales of Kansas thrifts.  The Board discussed the
  necessity to maximize shareholder value and to determine the value of Railroad
  should it be approached regarding a possible acquisition.  The Board also
  determined that it was advisable to employ an investment banking firm to
  discuss the procedures required if a decision was made to market Railroad and
  to determine the overall marketability of Railroad.  In July 1993, the Board
  of Directors of Railroad authorized management to invite several investment
  banking firms to make presentations regarding their respective approaches to
  determining the market valuation.
   
       In September 1993, Railroad engaged an investment banking firm to review
  strategic alternatives including the possibility of a sale or merger.  Several
  prospective purchasers were identified, including Commercial.  The Board of
  Directors of Railroad then authorized the preparation of a confidential
  memorandum to present on a limited basis and two of the identified companies
  were approached.  Commercial was not contacted at this time.  No prospects
  developed from these inquiries and Railroad terminated its engagement with its
  investment banking firm. Railroad paid a termination fee in the amount of 
  $50,000 to this investment banking firm.  Railroad paid a termination fee in 
  the amount of $50,000 to this investment banking firm.

       Railroad's expansion of loan origination offices continued into early
  1994 with openings in Branson, Missouri, Tulsa, Oklahoma and Olathe, Kansas.
  It also established a construction and permanent loan origination office in
  Las Vegas, Nevada.  During the same timeframe, Railroad expanded its branch
  operations by converting agent offices in Wellington, Kansas and Arkansas
  City, Kansas to full service branches.  In May 1994, Railroad Savings entered
  into contracts for the purchase of real estate in West Wichita and Derby,
  Kansas, to build new full service branches.

       On August 31, 1994, Railroad merged two of its wholly owned mortgage
  banking subsidiaries into its Railroad Savings subsidiary. This allowed
  Railroad Savings to reduce its operating expenses by consolidating certain
  functions into the Wichita, Kansas corporate headquarters operations.

       In late summer 1994, Railroad received a call from representatives of
  Piper Jaffray indicating that Commercial might be interested in entering into
  discussions with Railroad.  Railroad retained Piper Jaffray, in September
  1994, to initiate discussions with Commercial and, if authorized by the board
  of directors, other buyers and entered into an engagement letter to such
  effect on October 17, 1994.  At the same time, Railroad engaged

                                      17

  outside legal counsel.  Preliminary discussions began with Commercial and on
  October 6, 1994, Railroad and Commercial entered into a confidentiality
  agreement in consideration of a possible acquisition of Railroad by
  Commercial.  Preliminary discussions continued through October 1994 and
  included an extensive exchange of information between the two companies. The
  board, together with legal counsel and Piper Jaffray, reviewed this
  information and other material relating to the proposed transaction at its
  regularly scheduled board meeting in October, 1994. Legal counsel reviewed the
  board's fiduciary obligations and legal duties and management reviewed
  Railroad Savings' 1995 Business Plan and projections, taking into account
  projections from proposed accounting changes related to originated mortgage
  servicing rights. Piper Jaffray presented preliminary information regarding
  Commercial and its financial condition, the thrift industry and recent
  acquisitions in the thrift industry and the pro forma effect of a combination
  between Commercial and Railroad. After the conclusion of the presentation, the
  board authorized further discussions with Commercial relating to price and
  structure of a potential transaction. After a series of telephone call
  discussions with Commercial, the preliminary discussions broke off primarily
  due to failure of the parties to reach an agreement on price.

       Because preliminary merger discussions had ceased, Railroad continued its
  growth strategy by obtaining regulatory approval to accept deposits in three
  new offices:  East Wichita, West Wichita, and Lawrence, Kansas.  Railroad
  Savings also won a bid for the purchase of seven branches from First Bank, fsb
  Minneapolis, Minnesota. These branches are in the following Kansas
  communities: Greensburg, Larned, Colby, Oberlin, Osage City, Wamego and
  Fredonia. The purchase closed June 23, 1995. As a part of this transaction,
  agency offices in the Greensburg, Larned and Colby communities were
  consolidated into the new branch offices.
      
       In addition to branch expansion activities in early 1995, Railroad
  entered into discussions with another publicly traded thrift and exchanged
  information with a goal toward some type of business combination.  These
  discussions continued well into March 1995, although no agreement was reached 
  regarding basic terms, structure or price.      

       On or about March 21, 1995, representatives of Commercial contacted
  Railroad and the parties agreed to meet on March 27, 1995. Representatives of
  Railroad and Commercial met on that day for several hours and discussed
  resuming discussions and agreed to take the matter of new discussions to their
  respective boards. On March 28, 1995, the Board of Directors of Railroad
  agreed to entertain merger discussions with Commercial. Because of the time
  already devoted to discussions with Commercial and the commitment of time and
  resources associated with such discussions, Railroad advised management that
  such authorization was contingent on an agreement being reached prior to
  Railroad's April 21, 1995 Annual Meeting and gave management certain
  parameters as to pricing.

       On March 28, 1995, Railroad contacted outside securities legal counsel in
  anticipation of pursuing an agreement on structure and price with Commercial.
  On April 3, 1995, Railroad amended its prior engagement letter with Piper
  Jaffray and again sought its expertise in issuing a fairness opinion regarding
  the proposed transaction.  On April 10, 1995, the Chairmen and Presidents of
  both Railroad and Commercial met for several hours and agreed, subject to
  Board approval, to recommend a sale of Railroad to Commercial at $17.25 per
  share, again only if a definitive agreement could be executed prior to
  Railroad's Annual Meeting. The recommendation was presented to the Board at a
  Special Meeting held on April 13, 1995. At the meeting the Board authorized
  management to negotiate the definitive agreement and present it to the Board
  at a Special Meeting to be held on April 18, 1995.

       Management negotiated the definitive agreement, with assistance from
  Piper Jaffray and outside counsel, and presented it to the Board at a Special
  Meeting of the Board on April 18, 1995. At that meeting the Board reviewed,
  with counsel, its legal responsibilities as a Board, the text of the
  definitive agreement, and the fairness opinion presented by representatives of
  Piper Jaffray.

       Management terminated discussions with the other thrift immediately after
  execution of the definitive agreement with Commercial.

  Reasons for the Merger and Recommendations of the Railroad Board of Directors

       The terms of the Merger Agreement, including the consideration offered to
  Railroad's shareholders, were the result of arm's-length negotiations between
  Railroad and Commercial and their respective representatives. Railroad
  consulted with its own financial advisor and legal counsel during the course
  of negotiations. Railroad's Board of Directors believes that the Merger is
  fair to and in the best interest of shareholders of Railroad. In reaching a
  conclusion to approve the Merger, Railroad's Board of Directors considered a
  number of factors which, taken in totality, led to a determination by the
  Board of Directors that the Merger is in the best interest of Railroad and its
  shareholders. Railroad's Board of Directors did not assign any relative or
  specific weights to the factors considered. Among other things, the Railroad
  Board of Directors considered the following:

       (i) the premium represented by the consideration offered to Railroad's
  shareholders in relation to the book value per share of Railroad Common Stock;

      (ii) the multiple represented by the consideration offered to Railroad's
  shareholders in relation to per share book value and historical and projected
  earnings when compared to national and regional industry averages;

     (iii) the financial terms of other recent business combinations in the
  thrift industry and a comparison of the financial terms of the Merger to such
  other transactions;

      (iv) the fact that, over a three year period, Railroad communicated with
  a number of qualified and capable financial organizations; and that it engaged
  several investment bankers and entered into five confidentiality agreements
  with interested parties to discuss certain business consolidations and
  exchange information;

       (v) that Railroad and Commercial previously engaged in preliminary merger
  discussions which were terminated primarily due to a failure to agree on
  price;

      (vi) Commercial's favorable competitive position in its current markets
  and the few overlaps in the Commercial and Railroad branch networks;

     (vii) the market liquidity of Commercial Common Stock, the research
  coverage of Commercial Common Stock by industry analysts, and the established
  acquisition program of Commercial;

    (viii) the financial condition, results of operations, current business
  and expansion opportunities and constraints, and prospects of future
  performance and earnings of Railroad, on a stand-alone basis;

      (ix) the potential financial condition, results of operation,
  expansion opportunities and prospects of future performance and earnings of
  Railroad and Commercial on a combined basis;

       (x) the tax-free nature of the consideration to be received by Railroad
  stockholders;

      (xi) the probable impact of the Merger on customers and employees of
  Railroad and the communities served by Railroad; and

     (xii) the opinion of Piper Jaffray that the Merger Consideration to be
  received by Railroad shareholders was fair from a financial point of view as
  of the date of the opinion.

       THE RAILROAD BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE MERGER
  AGREEMENT AND THE MERGER BE ADOPTED AND APPROVED BY ALL SHAREHOLDERS OF
  RAILROAD.

   Financial Advisors and Opinions of Financial Advisors

       Piper Jaffray.  Piper Jaffray was engaged by Railroad in September 1994
  to approach Commercial and, with the consent of Railroad, other third parties
  regarding the possible business combination of Railroad with Commercial or one
  of such third parties, to assist in structuring and negotiating a possible
  business combination transaction, and to render its opinion regarding the
  fairness, from a financial point of view, of the consideration proposed to be
  paid to the holders of Railroad Common Stock in such a combination.  Piper
  Jaffray and Railroad executed an engagement letter to such effect on October
  17, 1994, and the letter was amended on April 3, 1995.  Piper Jaffray
  delivered to Railroad's directors on April 18, 1995 its opinion to the effect
  that, as of the date of the opinion and based upon and subject to the
  assumptions, factors and limitations set forth in the opinion and as described
  below, the consideration proposed to be paid to the holders of Railroad Common
  Stock in the Acquisition Merger was fair, from a financial point of view, to
  such stockholders.  This opinion was subsequently reaffirmed by issuance to
  the Railroad Board of a Piper Jaffray opinion, dated August 9, 1995.  A copy
  of the Opinion letter dated August 9, 1995 is attached to this Proxy
  Statement/Prospectus as Appendix B and is incorporated herein by reference.
  The April 18, 1995 opinion is substantially identical to the opinion attached
  hereto as Appendix B.  Holders of Railroad Common Stock are urged to read the
  attached opinion in its entirety.
      
       Although Piper Jaffray acted as financial adviser, participated in
  certain discussions and provided certain analyses to the Railroad Board of
  Directors, Piper Jaffray was not requested to and did not make any
  recommendations to the Railroad Board of Directors as to the form or amount of
  consideration to be received by the stockholders of Railroad in the
  Acquisition Merger, which was determined through arm's-length negotiations
  between Commercial and Railroad. The opinion of Piper Jaffray is directed to
  the Railroad Board of Directors and does not constitute a recommendation
  to any Railroad stockholder as to how such stockholder should vote at the
  Special Meeting. Piper Jaffray was not requested to opine as to, and the
  opinion of Piper Jaffray does not address, Railroad's underlying business
  decision to proceed with or effect the Acquisition Merger.      

       In arriving at its opinion, Piper Jaffray reviewed, among other things,
  (i) the Merger Agreement, (ii) certain publicly available information relative
  to the business, financial condition and operations of Railroad, (iii) certain
  internal financial planning information of Railroad furnished by management of
  Railroad, (iv) certain financial and securities data of Railroad and companies
  deemed similar to Railroad or representative of the business sector in which
  Railroad operates, (v) to the extent publicly available, the financial terms
  of certain acquisition transactions, (vi) certain publicly available
  information relative to Commercial, (vii) certain internal financial planning
  information of Commercial furnished by management of Commercial, and
  (viii) certain financial and securities data of Commercial and companies
  deemed similar to Commercial or representative of the business sector in which
  Commercial operates.  In addition, Piper Jaffray engaged in discussions with
  members of management of Commercial and Railroad concerning the respective
  financial condition, current operating results and business outlook of
  Commercial and Railroad.

       In delivering its opinion to the Railroad Board of Directors on April 18,
  1995, Piper Jaffray prepared and delivered to the Railroad Board of Directors
  certain written materials containing various analyses and other information
  material to the opinion.  The following is a summary of these materials:

       Stock Trading Analyses.  Piper Jaffray reviewed the stock trading history
  of each of Railroad and Commercial.  Piper Jaffray presented the following
  stock trading data:

<TABLE>

                                                  Railroad  Commercial

                                      20
<PAGE>
    
    Piper Jaffray also analyzed the per share purchase price and the aggregate
  transaction value based on the collar structure set forth in the Merger
  Agreement. The analysis indicated that Railroad Common Stock was trading at
  the top of its 52-week trading range and that the Commercial Common Stock was
  trading at approximately $1 3/8 below the top of its 52-week trading range.
  The analysis also indicated that the trading price of Commercial Common Stock
  on April 17, 1995 was within ($.50 below the top of) the range of prices of
  Commercial Common Stock (the "Collar") that, if maintained during the
  Determination Period, would result in consideration to holders of Railroad
  Common Stock with a value of $17.25.     
   
       Comparable Transaction Analysis.  Piper Jaffray reviewed recent merger
  and acquisition transactions for which information was publicly available and
  which involved Midwest thrifts, a seller receiving consideration of between
  $25 million and $100 million and consideration comprised solely of stock and
  an announcement date after January 1, 1991.  This review produced 14
  transactions (the "Comparable Transactions") deemed relevant to the proposed
  Acquisition Merger.  Piper Jaffray presented the following valuation multiples
  for the Comparable Transactions:  price to latest 12 months (LTM) earnings per
  share (EPS) of 6.6x to 39.7x with a median of 16.0x and a mean of 16.8x; price
  to book value of 1.07x to 1.90x, with a median of 1.39x and a mean of 1.43x;
  price to tangible book value of 1.28x to 1.90x, with a median of 1.43x and a
  mean of 1.49x; price to total assets of 6.8% to 22.6% with a median of 13.0%
  and a mean of 13.6%; and price to total deposits of 7.4% to 28.3% with a
  median of 16.7% and a mean of 17.1%. With respect to the price to total assets
  ratio, Piper Jaffray noted that Railroad's return on assets was below the
  return on assets of any of the target institutions included in the Comparable
  Transactions. These ratios were compared to corresponding ratios for Railroad,
  assuming a $17.25 per share purchase price and financial information as of and
  for the 12 months ended December 31, 1994, of 20.2x, 1.51x, 1.54x, 6.8% and
  11.9%, respectively. Piper Jaffray also updated these ratios for Railroad
  based on preliminary results for the quarter ended March 31, 1995, calculating
  a price to LTM EPS of 15.5x, a price to book value of 1.40x, a price to total
  assets of 6.6% and a price to total deposits of 11.5%. In calculating a price
  to LTM EPS ratio for Railroad at March 31, 1995, Piper Jaffray adjusted EPS to
  remove the benefit of the gain on sale of one large REO property liquidated in
  the first quarter of 1995.     

       Piper Jaffray also calculated an implied percentage premium to holders of
  Railroad Common Stock based on a $17.25 purchase price and various prices for
  the Railroad Common Stock prior to announcement of the transaction (assumed to
  be April 18, 1995); and compared these implied premiums to those calculated
  for the Comparable Transactions.  This analysis produced a 45.3% implied
  premium in the Acquisition Merger over the price of Railroad Common Stock one
  trading day prior to announcement of the Acquisition Merger, which compared to
  a range of 6.8% to 69.4%, a median of 23.3% and a mean of 26.1% for the
  Comparable Transactions; a 51.6% implied premium in the Acquisition Merger
  over the price of Railroad Common Stock five trading days prior to
  announcement, which compared to a range of 4.5% to 77.3%, a median of 21.9%
  and a mean of 26.6% for the Comparable Transactions; and a 64.3% implied
  premium in the Acquisition Merger over the price of Railroad Common Stock 30
  trading days prior to announcement, which compared to a range of 0.3% to
  48.3%, a median of 34.0% and a mean of 28.5% for the Comparable Transactions.
      
       Dilution Analysis.  Piper Jaffray analyzed the hypothetical pro forma
  effects of the Acquisition Merger on Commercial's earnings per share for the
  years ending June 30, 1995 and 1996, assuming various Average Closing
  Prices of Commercial Common Stock and giving effect to proposed revisions to
  the accounting treatment of mortgage servicing rights.  Projected Commercial
  earnings, based on estimates published by the Institutional Brokers Estimate
  Service, were combined with projected stand alone Railroad earnings, and
  adjusted for the assumed realization of certain cost savings, non-recurring
  acquisition costs and other synergies anticipated by Commercial management in
  the Acquisition Merger.  Assuming adoption of the proposed changes in
  accounting for mortgage servicing rights and assuming an Average Closing
  Price of $25.63 for Commercial Common Stock, this analysis indicated that the
  Acquisition Merger would be dilutive to Commercial earnings per share by 3.2%
  and 0.3% in fiscal 1995 and fiscal 1996, respectively.  The analysis indicated
  that the Acquisition Merger would be dilutive to such earnings in fiscal 1995
  by 2.7% and accretive to such earnings by 0.2% in fiscal 1996 if the Average
  Closing Price of Commercial Common Stock is $27.00 or more, and dilutive
  to such earnings by 3.8% in fiscal 1995 and 1.0% in fiscal 1996 if the Average
  Closing Price of Commercial Common Stock is $24.00 or less.  The analysis
  indicated that the Acquisition Merger would be slightly less dilutive if the
  accounting changes were not adopted.      

       Comparable Public Company Analysis.  Piper Jaffray compared certain
  financial information and valuation ratios relating to Railroad and Commercial
  to corresponding data and ratios for groups of selected publicly traded
  companies deemed comparable to Railroad (the "Railroad Comparables") and to
  Commercial (the "Commercial Comparables").  The Railroad Comparables and the
  Commercial Comparables are collectively referred to as the

                                      21
<PAGE>
 
  "Comparable Companies".  The Railroad Comparables comprised 11 publicly traded
  savings institutions and savings and loan holding companies headquartered in a
  13 state region in the Midwestern United States with assets between $200
  million and $1.7 billion.  The Commercial Comparables comprised seven publicly
  traded savings institutions and savings and loan holding companies
  headquartered in the same 13 state region, but with assets between $4.0
  billion and $12.5 billion.  The data and ratios for both the Railroad
  Comparables and the Commercial Comparables were computed using the closing
  price of the Comparable Companies as of April 17, 1995 and financial results
  as of and for the year ended December 31, 1994.

       Piper Jaffray calculated valuation ratios for the Railroad Comparables as
  follows:  price to LTM EPS of 6.4x to 12.7x, with a median of 9.8x and a mean
  of 9.8x; price to calendar 1995 EPS estimates of 7.6x to 11.7x, with a median
  of 9.9x and a mean of 9.8x; and price to book value of 0.79x to 1.36x, with a
  median of 1.12x and a mean of 1.11x.  These compared to corresponding ratios
  for Railroad, based on an assumed purchase price of $17.25 per share, of
  20.2x, 12.0x and 1.51x, respectively.

       Piper Jaffray calculated valuation ratios for the Commercial Comparables
  as follows: price to LTM EPS of 7.2x to 23.2x, with a median of 8.8x and a
  mean of 11.5x; price to calendar 1995 EPS estimates of 6.9x to 12.6x, with a
  median of 7.8x and a mean of 8.3x; and price to book value of 0.99x to 1.66x,
  with a median of 1.28x and a mean of 1.32x.  These compared to corresponding
  ratios for Commercial, based on the closing price of Commercial Common Stock
  on April 17, 1995 and financial results as of and for the year ended December
  31, 1994, of 8.0x, 7.3x and 1.20x, respectively.

       Piper Jaffray noted that the above multiples for Comparable Companies and
  Railroad were derived from stock prices that represent prices at which small
  blocks of stock could be purchased or sold.  Such stock prices may not be
  indicative of the price at which 100% of the stock of the Comparable Companies
  and Railroad could be purchased or sold.

       In reaching its conclusion as to fairness of the consideration to be
  received in the Acquisition Merger and in its presentation to the Railroad
  Board of Directors, Piper Jaffray did not rely on any single analysis or
  factor described above, assign relative weights to the analyses or factors
  considered by it, or make any conclusions as to how the results of any given
  analysis, taken alone, supported its opinion.  The preparation of a fairness
  opinion is a complex process and not necessarily susceptible to partial
  analyses or summary description.  Piper Jaffray believes that its analyses
  must be considered as a whole and that selecting portions of its analyses and
  of the factors considered by it, without considering all factors and analyses,
  would create a misleading view of the process underlying the Piper Jaffray
  opinion.  The analyses of Piper Jaffray are not necessarily indicative of
  actual values or future results, which may be significantly more or less
  favorable than suggested by such analyses.  Analyses relating to the value of
  companies do not purport to be appraisals or valuations or necessarily reflect
  the price at which companies may actually be sold.  No company or transaction
  used in any comparable analysis as a comparison is identical to Commercial,
  Railroad or the Acquisition Merger.  Accordingly, an analysis of the results
  is not mathematical; rather, it involves complex considerations and judgments
  concerning differences in the various characteristics of the Comparable
  Transactions to which the Acquisition Merger was compared and in the financial
  and operating characteristics of the Comparable Companies and other factors
  that could affect the public trading value of the Comparable Companies to
  which Railroad and Commercial were compared.

       For purposes of its opinion, Piper Jaffray relied upon and assumed the
  accuracy, completeness and fairness of the financial and other information
  made available to it and did not attempt independently to verify such
  information.  Piper Jaffray relied upon the assurances of Railroad and
  Commercial managements that the information provided by Railroad and
  Commercial had a reasonable basis and, with respect to financial planning data
  and other business outlook information, reflected the best available
  estimates, and that they were not aware of any information or fact that would
  make the information provided to Piper Jaffray incomplete or misleading.  In
  arriving at its opinion, Piper Jaffray did not perform, nor was it furnished,
  any appraisal or valuation of specific assets or liabilities of Railroad or
  Commercial and expressed no opinion regarding the liquidation value of any
  entity.  No limitations were imposed by Railroad on the scope of Piper
  Jaffray's investigation or the procedures to be followed in rendering

                                      22
<PAGE>
 
  its opinion.  Piper Jaffray expressed no opinion as to the price at which
  shares of Commercial Common Stock may trade at any future time.  The Piper
  Jaffray opinion is based upon information available to Piper Jaffray and the
  facts and circumstances as they existed and were subject to evaluation on the
  dates of the opinion.  Events occurring after such dates could materially
  affect the assumptions used in preparing the opinion.

       Piper Jaffray, as a customary part of its investment banking business, is
  engaged in the evaluation of businesses and their securities in connection
  with mergers and acquisitions, underwritings and other distributions of
  securities, private placements and evaluations for estate, corporate and other
  purposes.  The Railroad Board of Directors selected Piper Jaffray because of
  its expertise, reputation and familiarity with the financial services industry
  in general and the Midwestern banking market and Railroad in particular.

       Piper Jaffray has provided financial advisory and investment banking
  services to Railroad since 1991.  Piper Jaffray acted as underwriter for a
  public offering of senior notes of Railroad completed in January 1992.  Piper
  Jaffray makes a market in the senior notes and has published market research
  on Railroad.  Piper Jaffray also acted as the managing underwriter of a public
  offering of Commercial subordinated notes in 1992, has published market
  research on Commercial, and is a market maker in such notes and in Commercial
  Common Stock.  In the normal course of its market making activities, Piper
  Jaffray may, from time to time, have a long or short position in and buy and
  sell Railroad and Commercial securities, which positions, on occasion, may be
  material in size relative to the volume of trading activity.
      
       For acting as financial advisor to Railroad, Railroad has agreed to pay
  Piper Jaffray a fee of 1.5% of the consideration paid in the Acquisition
  Merger to the extent such consideration does not exceed $35 million plus 3% of
  such consideration in excess of $35 million. The aggregate amount of the fee
  payable to Piper Jaffray will depend on the amount of consideration received
  by Railroad shareholders which will, in turn, depend on the Average Closing
  Price during the Determination Period. If, for example, the Average Closing
  Price is equal to $31.625 (the closing price of Commercial Common Stock on
  August 10, 1995) the aggregate fees paid to Piper Jaffray would be
  approximately $815,650. An aggregate of $200,000 of such fees are due on or
  before the date Piper Jaffray renders its updated fairness opinion and the
  balance (approximately $615,650 if the Average Closing Price is $31.625) is
  contingent on, and due upon, consummation of the Acquisition Merger. Whether
  or not the Acquisition Merger is consummated, Railroad has agreed to pay the
  reasonable out-of-pocket expenses of Piper Jaffray (subject to the approval 
  of Railroad if in excess of $35,000) and to indemnify Piper Jaffray against 
  certain liabilities incurred (including liabilities under the federal 
  securities laws) in connection with the engagement of Piper Jaffray by 
  Railroad.

       The full text of Piper Jaffray's written opinion of August 9, 1995,
  which sets forth the assumptions made, procedures followed, and limitations on
  reviews undertaken, is attached as Annex B to this Proxy Statement.  The
  summary of Piper Jaffray's written opinion set forth in this Prospectus/Proxy
  Statement is qualified in its entirety by reference to the opinion.  Railroad
  stockholders are urged to read the Piper Jaffray opinion in its entirety.

       Piper Jaffray's opinion does not constitute a recommendation to any
  stockholder of Railroad as to how such stockholder should vote with respect to
  the Merger Agreement and the Acquisition Merger.
      
       Merrill Lynch.  On September 29, 1994, Commercial retained Merrill Lynch
  to act as its exclusive financial advisor in connection with the Merger.
  Representatives of Merrill Lynch attended the meeting of the Board of
  Directors of Commercial held on April 18, 1995 at which Commercial's Board of
  Directors approved the Merger Agreement and the Stock Option Agreement.  At
  this meeting, Merrill Lynch rendered its written opinion to the effect that,
  as of such date, the Exchange Ratio was fair to Commercial from a financial
  point of view, which opinion is still in effect as of the date hereof. Merrill
  Lynch was not requested to and did not make any recommendations to the
  Commercial Board of Directors as to the form or amount of consideration to be
  paid to the stockholders of Railroad in the Acquisition Merger, which was
  determined through arms-length negotiations between Commercial and Railroad.
      
       In arriving as its written opinion, Merrill Lynch, among other things,
  reviewed selected financial and other information concerning Commercial and
  Railroad, including publicly-available reports and internal projections and
  forecasts, and information concerning comparable companies and comparable
  thrift acquisition and merger transactions.  In connection with rendering its
  opinion, Merrill Lynch performed a variety of financial analyses.  In
  preparing its opinion, Merrill Lynch assumed and relied upon the accuracy and
  completeness of all the financial and other information reviewed by it for
  purposes of the opinion, and did not independently verify such information or


                                      23
<PAGE>
 
  undertake any independent evaluation or appraisal of the assets or liabilities
  of Commercial or Railroad nor was it furnished with any such evaluation or
  appraisal.  Merrill Lynch is not an expert in the evaluation of allowance for
  loan losses, and it has not made an independent evaluation of the adequacy of
  the allowance for loan losses of Commercial or Railroad nor has it reviewed
  any individual credit files, and it has assumed that the aggregate allowance
  for loan losses is adequate to cover such losses and will be adequate on a pro
  forma basis for the combined entity.

       In arriving at its written opinion, Merrill Lynch also assumed and relied
  upon the senior management of Commercial as to the reasonableness and
  achievability of the financial and operating forecasts furnished by Commercial
  and Railroad (and the assumptions and bases therefor).  Merrill Lynch, with
  the consent of Commercial, assumed that such information, including, without
  limitation, financial forecasts, projected cost savings and operating
  synergies resulting from the Merger and projections regarding underperforming
  and nonperforming assets, net charge-offs, and adequacy of reserves, reflect
  the best currently available estimates and judgment of the senior management
  of Commercial and Railroad as to the expected future financial performance of
  Commercial, Railroad, or the combined entity, as the case may be.  The opinion
  was based on economic, market and other conditions as in effect on, and the
  information made available to Merrill Lynch on, the date the opinion was
  rendered.  The opinion also was rendered without regard as to the necessity
  for, or level of, any restrictions, obligations, undertakings or divestitures
  which may be imposed or required in the course of obtaining regulatory
  approvals for the Merger.
      
       Merrill Lynch has received a $150,000 fee for investment banking services
  related to the Merger and related advisory work and will receive an additional
  $125,000 fee upon consummation of the Merger. Merrill Lynch will also be
  reimbursed for its out-of-pocket expenses and will be indemnified against
  certain liabilities relating to or arising out of the Merger, including
  liabilities arising under the securities laws. In addition, Merrill Lynch has
  from time to time provided financial advisory services to Commercial for which
  it has received customary compensation. In the ordinary course of its
  business, Merrill Lynch may also trade the securities of Commercial and/or
  Railroad for its own account and the accounts of customers and, accordingly,
  may also from time to time hold a long or short position in such securities.
      
       Merrill Lynch's opinion was rendered to the Board of Directors of
  Commercial and does not constitute, and should not be construed as, a
  recommendation to any shareholder of Railroad as to how such shareholder
  should vote at the Special Meeting.

  Conversion of Railroad Common Stock
      
       Exchange Ratio.  Each share of Railroad Common Stock issued and
  outstanding at the Acquisition Merger Effective Time (other than shares owned
  or held by Commercial) will be converted into and represent solely the right
  to receive a number of shares of Commercial Common Stock that have a value
  equal to $17.25 (such number of shares referred to as the "Exchange Ratio"),
  such value to be based upon the "Average Closing Price" of Commercial Common
  Stock (i.e., the arithmetic mean of the per share closing prices of Commercial
  Common Stock as reported on the NYSE for the Determination Period; provided,
  however, that (1) if such Average Closing Price of the Commercial Common Stock
  is greater than $27.00 or less than $24.00, the Exchange Ratio shall be .6389
  and .7188 shares, respectively, of Commercial Common Stock, (2) if the Average
  Closing Price of the Commercial Common Stock is less than $20.00 and the
  decline in the price of Commercial Common Stock during the period beginning on
  April 17, 1995 and ending on the last date utilized in the calculation of the
  Average Closing Price exceeds by more than 15% any decline in the weighted
  stock price of the Index Group during the same period, Railroad will have the
  right to terminate the Merger Agreement unless Commercial exercises its option
  to adjust the Exchange Ratio to equal $14.38 divided by the Average Closing
  Price of Commercial Common Stock. Trading of the Commercial Common Stock on
  the NYSE commenced August 2, 1995. Prior to that date, the Commercial Common
  Stock was quoted on the Nasdaq National Market. Any references herein to the
  closing price of the Commercial Common Stock for the period up to and
  including August 1, 1995 shall be to the closing price as reported on the
  Nasdaq National Market. Based on the closing price per share of Commercial
  Common Stock on the NYSE on August 10, 1995, of $31.625, each share of
  Railroad Common Stock would be exchanged for .6389 shares of Commercial Common
  Stock. Such Exchange Ratio may increase or decrease depending on the Average
  Closing Price of Commercial Common Stock. Cash will be paid in lieu of
  fractional shares.     

                                      24
<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 Closing Price for shares of Commercial Common Stock.
       
       Exchange of Railroad Stock Certificates.  Chemical Bank/GeoServe is
  expected to act as the 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, the Exchange Agent
  will send a notice and transmittal form to each Railroad stockholder of record
  at such date whose Railroad 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 Railroad Common Stock in exchange for new
  certificates for Commercial Common Stock.  Promptly following receipt of such
  notice and transmittal form, holders of Railroad Common Stock certificates
  should surrender their certificates in accordance with the specified
  procedures.  Upon surrender, each Railroad Common Stock certificate will be
  cancelled.

       Until surrendered, certificates that prior to the effective date of the
  Acquisition Merger represented outstanding shares of Railroad Common Stock
  will be deemed for all corporate purposes to evidence ownership of the number
  of whole shares of Commercial Common Stock into which such shares of Railroad
  Common Stock have been converted.  Until such certificates are so surrendered,
  no dividend 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 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 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 issuance 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 Railroad Common Stock should NOT surrender their certificates
  until they receive written instructions from the Exchange Agent.
 
       Any shares of Railroad Common Stock owned or held by Commercial or any of
  its subsidiaries (other than in a fiduciary capacity) or by Railroad 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 cancelled.

  Treatment of Railroad Stock Options

       At the Acquisition Merger Effective Time, each outstanding option under
  the Railroad Option Plans will continue outstanding as an option to purchase
  the number of shares (rounded down to the nearest whole share) of Commercial
  Common Stock that would have been received by the optionee in the Merger had
  the option been exercised in full (without regard to any limitations on
  exercise) for shares of Railroad Common Stock immediately prior to the
  Acquisition Merger.  Such options shall remain outstanding on the same terms
  and conditions under the relevant option as were applicable immediately prior
  to the Acquisition Merger Effective Time, except for appropriate pro rata
  adjustments as to the option price for shares of Commercial Common Stock
  substituted therefor so that the


                                      25
<PAGE>
 
  aggregate option exercise price of shares subject to an option immediately
  following the assumption and substitution will be the same as the aggregate
  option exercise price for such shares immediately prior to such assumption and
  substitution. In addition, under Railroad's 1994 Stock Option and Incentive 
  Plan, all options will become fully vested upon consummation of the Merger.

       See " -- Interests of Certain Persons in the Merger" for information
  regarding outstanding Railroad stock options.

  No Dissenters' Appraisal Rights

       Section 262(b)(1) of the Delaware General Corporation Law expressly
  denies appraisal rights to stockholders of a corporation whose stock is listed
  on a national securities exchange.  Because Railroad's common stock is listed
  on the American Stock Exchange, which is a national securities exchange,
  Railroad's stockholders will not be entitled to appraisal rights in connection
  with the Merger.

  The Bank Merger

       Following the Acquisition Merger, Railroad Savings 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
  Railroad Savings and the Bank dated April 18, 1995.  At the Bank Merger
  Effective Time, the shares of Railroad Savings common stock issued and
  outstanding immediately prior thereto will be cancelled 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
  Railroad Savings and all branch offices of the Bank and former branch offices
  and agency offices of Railroad Savings will be branch and agency 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.

  Management after the Merger

       The directors and officers of Commercial will not be affected by the
  Merger.  The directors of the Bank will not be affected by the Merger.  With
  the exception of the addition of Mr. Gary L. Baugh (currently President and
  Chief Operating Officer of Railroad), who will serve Commercial as Senior Vice
  President and State Director, Kansas Operations following the Merger, the
  officers of the Bank will not be affected by the Merger.

  Representations and Warranties

       Commercial and the Bank, and Railroad and Railroad Savings, have given
  certain representations and warranties to each other in the Merger Agreement
  relating to, among other things, the following: the validity of their

  Railroad Savings' loan portfolio; the adequacy of the present carrying values
  of any real estate investments, joint ventures, construction loans or other

  undisclosed derivative contracts; and the adequacy of certain types of
  insurance.

  Covenants Pending the Acquisition Merger

       In the Merger Agreement, Commercial, the Bank, Railroad and Railroad
  Savings have agreed to use their best efforts, and to take all actions
  necessary or appropriate, to consummate the transactions contemplated by the
  Merger Agreement.  Each party has also agreed to give to the other party and

  any governmental approvals contemplated in the Merger Agreement, (ii)
  adversely affect Railroad's ability to perform its obligations under the
  Merger Agreement or the Stock Option Agreement or (iii) adversely affect the

  (other than with respect to security interests in properties securing loans
  and properties acquired in settlement of loans in the ordinary course) or
  improvements to real property;

  other governing instruments of Railroad or any of its subsidiaries, except as

  any bonus type payment, except


                                      27

  that bonuses may be paid from Railroad's formula bonus arrangement disclosed

       (viii)  engage in any lending activities other than in the ordinary

  7701(a)(19) of the Internal Revenue Code of 1986, as amended (the "Code");

       (xiii)  make (a) any acquisition and development or land acquisition

       Pursuant to the Merger Agreement, Railroad also shall not authorize or
  permit any representative of Railroad or any subsidiary to initiate contact

  Merger Agreement, for a merger or other business combination involving
  Railroad or Railroad Savings, for the acquisition of a 10.0% or greater equity


                                      28
<PAGE>
 
  interest in Railroad or Railroad Savings or for the acquisition of a
  substantial portion of the assets of Railroad or Railroad Savings) or, except
  as the fiduciary duties of Railroad's Board of Directors may otherwise
  require, cooperate with, negotiate with or enter into an agreement with any
  party relating to a takeover proposal.  Further, Railroad has agreed to give
  prompt written notice to Commercial upon becoming aware of any takeover
  proposal.

  addition to governmental approvals, Commercial and the Bank shall have

       There can be no assurance that the conditions to consummation of the
  Merger will be satisfied or waived.  In the event the conditions to either
  party's obligations become impossible to satisfy in any material respect, the
  other party may elect to terminate the Merger Agreement.  See " -- Amendment
  or Termination of the Merger Agreement."

  Amendment or Termination of the Merger Agreement
      
       The Merger Agreement may be terminated at any time before the Acquisition
  Merger Effective Time, whether before or after approval by stockholders; (i)
  by mutual consent of the parties; (ii) at the election of either party, if the
  closing of the Merger shall not have occurred on or before March 31, 1996 or
  such later date as may be agreed to in writing by the parties, provided that
  the right to terminate under this provision shall not be available to any
  party whose failure to 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 Railroad if
  any event occurs which renders impossible satisfaction in any material respect
  of one or more of the conditions to the obligations of Commercial to effect
  the Merger as set forth in the Merger Agreement and noncompliance is not
  waived by Commercial, provided that the right to terminate under this
  provision due to the failure to obtain a Phase I Environmental Risk Report
  expires on August 16, 1995; (iv) by Railroad upon delivery of written notice
  of termination to Commercial if any event occurs which renders impossible
  satisfaction in any material respect of one or more of the conditions to the
  obligations of Railroad to effect the Merger set forth in the Merger Agreement
  and noncompliance is not waived by Railroad; (v) by Railroad at any time
  during the two business days commencing on the business day immediately
  following the end of the Determination Period, if the Average Closing
  Price of Commercial Common Stock is less than $20.00 and the decline in the
  price of Commercial Common Stock during the period beginning on April 17, 1995
  and ending on the last date utilized in the calculation of the Average 
  Closing Price exceeds by more than 15% any decline in the weighted stock price
  of the Index Group during the same period; provided, however, that Railroad
  shall not be entitled to terminate the Merger Agreement on this basis if
  Commercial exercises its option to adjust the Exchange Ratio so that it equals
  the number obtained by dividing $14.38 by the Average Closing Price of
  Commercial Common Stock.      

       The representations, warranties and agreements of the parties set forth
  in the Merger Agreement shall not survive the Acquisition Merger Effective
  Time, and shall be terminated and extinguished at that time.  From and after
  that time, none of the parties shall have any liability to the other on
  account of any breach or failure of any of those representations, warranties
  and agreements, except with respect to agreements of the parties which by
  their terms are intended to be performed after that time and with respect to
  liability for fraud, deception or intentional misrepresentation.

       The Merger Agreement may be amended, whether before or after approval by
  stockholders of Railroad, by an agreement in writing executed in the same
  manner as the Merger Agreement and authorized or ratified by the Boards of
  Directors of Railroad and Commercial, except that after approval of the Merger
  Agreement by Railroad's stockholders, no such amendment without further
  approval by Railroad's stockholders may change the amount or form of the
  consideration to be received by Railroad's stockholders in the Merger.

  Stock Option Agreement

       As a condition to Commercial's entry into the Merger Agreement, Railroad
  and Commercial entered into a Stock Option Agreement dated April 18, 1995,
  pursuant to which Railroad granted to Commercial an option to purchase shares
  of authorized and unissued or treasury shares of Railroad Common Stock in an
  amount up to 13.0% of the outstanding shares of such stock at an exercise
  price of $11.875 per share, subject to adjustment, upon or after the
  occurrence of a "purchase event" (generally, (i) the entry by Railroad or
  Railroad Savings into an agreement with a person (other than Commercial or any
  of its affiliates) (a) to merge or consolidate with, or enter into any similar
  transaction with, Railroad or Railroad Savings, (b) to purchase, lease or
  otherwise acquire all or substantially all of the assets of Railroad or
  Railroad Savings or (c) to purchase or otherwise acquire (including by way of
  merger, consolidation, share exchange or any similar transaction) securities
  representing 10.0% or more of the voting power


                                      31
<PAGE>
 
  of Railroad or Railroad Savings; or (ii) the acquisition by any person (other
  than Commercial or its affiliates) of beneficial ownership of 25.0% or more of
  the outstanding shares of Railroad's common stock, the merger, consolidation
  or entry into a similar transaction by any person with Railroad or any of its
  subsidiaries or the purchase, lease or other acquisition by any person of all
  or substantially all of the assets of Railroad or any of its subsidiaries).

       Subject to compliance with applicable law and regulation (including any
  regulatory approvals required to be obtained by Railroad prior to issuing the
  shares subject to the option), unless Commercial shall have breached in any
  material respect any material covenant contained in the Merger Agreement and
  such breach has not been cured, the option may be exercised, in whole or part,
  at any time or from time to time only upon or after the occurrence of a
  purchase event.  Railroad shall notify Commercial promptly in writing of the
  occurrence of any transaction or event which constitutes a purchase event.  If
  more than one of the transactions, offers or events giving rise to a purchase
  event is undertaken or effected by the same person or occurs at the same time,
  then all such transactions and events shall give rise only to one purchase
  event, which purchase event shall be deemed continuing for all purposes until
  all such transactions are terminated or abandoned by such person and all such
  events have ceased or ended.

       To exercise the option, Commercial shall send to Railroad a written
  notice specifying (i) the total number of shares it will purchase pursuant to
  such exercise and (ii) a place and date not earlier than three business days
  nor later than 20 business days from the notice date for the closing of such
  purchase with respect to such exercise; however, if prior notification to or
  approval of any federal or state regulatory agency is required in connection
  with such purchase, Commercial and the Bank shall promptly file the required
  notice or application for approval and expeditiously process the same, and the
  period of time that otherwise would run pursuant to this sentence shall run
  instead from the date on which the last required notification period has
  expired or been terminated or such approvals have been obtained and any
  requisite waiting periods shall have passed.

       Commercial has the right to transfer or assign the option following the
  occurrence of a purchase event.  Prior to any such transfer or assignment,
  Commercial is required to give written notice of the proposed transfer or
  assignment to Railroad, who may within 24 hours of the receipt of such notice
  purchase the option at a price and on terms at least as favorable to
  Commercial as are set forth in the notice.

       The option shall expire and terminate, to the extent not previously
  exercised, upon the earlier of (i) the Acquisition Merger Effective Time; (ii)
  the date on which the Merger Agreement is terminated (other than a termination
  based upon (a) a willful breach by Railroad or Railroad Savings of any of
  their covenants under the Merger Agreement or (b) the failure of Railroad or
  Railroad Savings to obtain stockholder approval of the transactions
  contemplated by the Merger Agreement) if prior thereto a purchase event or a
  "proposal" (generally, a proposal by any person (other than Commercial or its
  affiliates) by public announcement or written communication, or in any
  application to any federal or state regulatory authority, (a) to acquire,
  merge, consolidate with or enter into any similar transactions with Railroad
  or Railroad Savings, (b) to purchase, lease or otherwise acquire all or
  substantially all of the assets of Railroad or Railroad Savings or (c) to
  purchase or otherwise acquire (including by way of merger, consolidation,
  share exchange or any similar transaction) securities representing more than
  15.0% of the voting power of Railroad) has not occurred or has not been made;
  (iii) 18 months after the later of (a) the occurrence of a purchase event or
  (b) the making of a proposal; however, if a proposal shall be made during the
  term of the Stock Option Agreement and prior to the occurrence of a purchase
  event and subsequent thereto a purchase event occurs then the option shall be
  further extended to expire upon the expiration of 18 months from the date of
  occurrence of such purchase event; (iv) 18 months after the termination of the
  Merger Agreement for the reasons set forth in (ii)(a) or (b) above; or (vi)
  such other date as to which the holder of the option and Railroad shall agree.

       The Stock Option Agreement is attached as Annex C hereto, and the
  description herein of the Stock Option Agreement is qualified in its entirety
  by reference to the Stock Option Agreement.

  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 duly burdensome (for example, denial of the request to
  operate, maintain, and replace the Railroad Savings agency offices to the same
  extent as Railroad Savings currently operates, maintains and replaces such
  agency offices (for more information, see " -- Conditions to Consummation of
  the Merger")).  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 Railroad'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.  All expenses in connection with the
  printing and mailing of this Prospectus/Proxy Statement shall be incurred by
  Railroad.

  Closing; Merger Effective Times

       As promptly as practicable following the satisfaction or waiver of all
  conditions of the Merger Agreement, a 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 which is the
  later of the time at which (i) the Nebraska articles of merger is filed with
  the appropriate authorities in Nebraska and (ii) the Delaware certificate of
  merger is filed with the appropriate authorities in Delaware.  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 Railroad and
  Railroad Savings who become employees of Commercial and/or the Bank shall be
  entitled to participate in all benefit plans sponsored by Commercial or the
  Bank to the same extent as other similarly situated employees of Commercial
  and the Bank, and Commercial shall honor all accrued vacation leave for the
  employees of Railroad and Railroad Savings.

       options are fully vested at time of grant.
  (2)  Granted under the Company's 1994 Stock Option and Incentive Plan.
       Options granted to officers are subject to a vesting schedule of 1/36th
       per month.  Under the terms of this plan, however, all options will
       become fully vested upon consummation of the Merger.
  (3)  Granted under the 1991 Directors' Stock Option Plan.

   
       Severance Benefits. Railroad Savings maintains a Reduction in Force Plan
  ("RIF") which Commercial intends to honor in connection with the Merger. The
  RIF provides for the following severance benefits to officers of Railroad
  Savings: Senior Vice Presidents, all Vice Presidents and Assistant Vice
  Presidents with five or more years of service receive two months' severance;
  and Assistant Vice Presidents with fewer than five years of service receive
  one month's severance. Specifically, under the RIF, Robert D. Taylor will
  receive $28,605, Donald J. Voth will receive $12,308, Kari S. Schmidt will
  receive $12,688 and all executive officers of Railroad as a group will
  receive in the aggregate $277,000. However, this amount is expected to be
  reduced substantially if the sale of Railroad's California mortgage banking
  operations and its wholesale lending operations in Las Vegas, Nevada to CUB
  Funding Corporation is consummated before the Merger because several
  individuals will no longer be eligible to receive payments under the RIF.

   Indemnification of Railroad Management

       Indemnification of Railroad Management.  Pursuant to the Merger
  Agreement, Commercial has agreed that for a period of six years following the
  Acquisition Merger Effective Time, the Merger will not affect or diminish any
  of Railroad's duties and obligations of indemnification existing as of the
  Acquisition Merger Effective Time in favor of employees, agents, directors or
  officers of Railroad or any of its subsidiaries arising by virtue of
  Railroad's certificate 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 Railroad immediately
  prior to the Acquisition Merger Effective Time to be covered for a period of
  three years from the Acquisition Merger Effective Time by the directors' and
  officers' liability insurance policy maintained by Railroad (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 Railroad to maintain or procure insurance coverage for such three
  year period pursuant to the Merger Agreement.

  Federal Income Tax Consequences

       Commercial and Railroad have not sought a ruling from the IRS concerning
  the federal income tax consequences of the Merger.  Instead, Commercial and
  Railroad will rely upon an opinion of Deloitte & Touche LLP, tax advisor to
  Commercial, to the following effect:

       .    the Acquisition Merger and the Bank Merger will each qualify as a
            "reorganization" under Section 368(a) of the Internal Revenue Code;

       .    no gain or loss will be recognized by Commercial, the Bank, Railroad
            or Railroad Savings by reason of the Acquisition Merger or the Bank
            Merger;

       .    no gain or loss will be recognized by Railroad stockholders (except
            in connection with the receipt of cash in lieu of fractional share
            interests in Commercial Common Stock) upon the exchange of Railroad
            Common Stock for Commercial Common Stock in the Merger;

       .    the basis of the Commercial Common Stock received by Railroad
            stockholders whose Railroad Common Stock is exchanged for Commercial
            Common Stock will be the same as the basis of the Railroad Common
            Stock surrendered in exchange therefor (subject to any adjustments
            required as the result of receipt of cash in lieu of fractional
            share interests in Commercial Common Stock);

       .    the holding period of the Commercial Common Stock received by
            Railroad stockholders whose Railroad Common Stock is exchanged for
            Commercial Common Stock will include the period during which the
            Railroad Common Stock surrendered in exchange therefor was held
            (provided that the stockholder's Railroad Common Stock was held as a
            capital asset at the Acquisition Merger Effective Time); and

       .    cash received by Railroad stockholders in lieu of fractional share
            interests in Commercial Common Stock will be treated as having been
            received as distributions in full payment in exchange for the
            fractional share interests in Commercial Common Stock which they
            would otherwise be entitled to receive and will qualify as capital
            gain or loss (assuming that the Railroad Common Stock was a capital
            asset in his hands at the Acquisition Merger Effective Time).


                                      35
<PAGE>
 
  Unlike a ruling from the IRS, 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 Railroad 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 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 RAILROAD STOCKHOLDER'S SITUATION.  EACH
  RAILROAD 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 is expected to be accounted for as a pooling of interests.
  Under this method of accounting, the recorded assets and liabilities of
  Commercial and Railroad will be carried forward to the surviving corporation
  in the Merger (Commercial) at their recorded amounts; income of the surviving
  corporation will include income of Commercial and Railroad for the entire
  fiscal year in which the Merger occurs; and the reported income of Commercial
  and Railroad for prior periods will be combined and restated as retained
  earnings of the surviving corporation (Commercial).  The consummation of the
  Merger is conditioned upon the receipt by Commercial from the independent
  public accountants for Commercial, of a letter dated at the Acquisition Merger
  Effective Time stating their opinion that the Merger should be accounted for
  by Commercial as a pooling of interests for financial statement purposes and
  that such accounting treatment is in accordance with generally accepted
  accounting principles.

  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 Railroad 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
  Railroad 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.
  Commission guidelines regarding qualifying for the pooling of interests method
  of accounting also limit sales by affiliates of the acquiring and acquired
  company in a business combination.  The guidelines indicate that the pooling
  of interests method of accounting will generally not be challenged on the
  basis of sales by affiliates


                                      36
<PAGE>
 
  of the acquiring or acquired company if they do not dispose of any of the
  shares of the corporation they own or shares of a corporation they receive in
  connection with a merger during the period beginning 30 days before the merger
  and ending when financial results covering at least 30 days of post-merger
  operations of the combined entity have been published.

       Railroad 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 and for purposes of qualifying the Merger for
  pooling of interests accounting treatment) of Railroad to deliver to
  Commercial a written agreement intended to ensure compliance with the
  Securities Act and to preserve the ability to treat the Merger as a pooling of
  interests.
      
  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 Railroad
  Common Stock is required for Railroad's stockholders to approve the Merger
  Agreement and the Acquisition Merger.  Each share of Railroad Common Stock
  outstanding at the close of business on the record date for the Special
  Meeting, August 9, 1995, is entitled to one vote on each matter to be
  considered at such meeting.  Railroad's directors and officers, and their
  affiliates, are expected to vote substantially all of the 651,969 shares, or
  30.6%, of Railroad's outstanding common stock (excluding stock options)
  beneficially owned by them as of the record date for approval of the
  Acquisition Merger and the Merger Agreement.

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

  Unaudited Pro Forma Combined Statement of Financial Condition

       The following unaudited pro forma combined statement of financial
  condition for Commercial has been prepared based on the historical
  consolidated statements of financial condition for Commercial and Railroad at
  March 31, 1995. This unaudited pro forma statement gives effect to the Merger
  accounted for as a pooling of interests, based on the conversion of each
  outstanding share of Railroad Common Stock into .6389 of a share of Commercial
  Common Stock, which would have been the applicable Exchange Ratio based on the
  Average NMS Closing Price for shares of Commercial Common Stock as of August
  10, 1995 ($31.45) if the Acquisition Merger had been consummated as of that
  date. For information regarding adjustment of the Exchange Ratio in the event
  the Average NMS Closing Price is lower than $24.00 or between $24.00 and
  $27.00 as of the Acquisition Merger Effective Time, see "The Merger --
  Conversion of Railroad Common Stock." The unaudited pro forma combined
  statement of financial condition should be read in conjunction with the
  historical consolidated financial statements and notes thereto incorporated by
  reference herein. The unaudited pro forma combined statement of financial
  condition presented on the following page does not include any expected cost
  savings as a result of the Merger, nor does it reflect merger transaction
  costs and is not necessarily indicative of the actual financial position that
  would have occurred had the Merger been consummated on March 31, 1995 or that
  may be obtained in the future.

       outstanding common stock ($.10 par value) totaling 2,116,074 shares
       consisting of 2,205,083 shares issued net of 89,009 shares held as

       Commercial Common Stock would be at least $27.00 per share.  No
       consideration was given for fractional shares in these pro forma
       adjustments.  Fractional shares will be paid in cash.

  Unaudited Pro Forma Combined Earnings Per Share Data

       The following table presents selected per share data for Commercial and
  Railroad on a historical and pro forma basis as if the Merger had been
  effective as of the dates or the beginning of the periods indicated.
      
       The Merger will be accounted for under the pooling of interests method,
  and pro forma data is derived in accordance with such method. The Railroad pro
  forma equivalent amounts are presented with respect to each set of pro forma
  data. Such pro forma equivalent per share amounts as to net income (loss) from
  continuing operations and book value are computed by multiplying the pro forma
  combined amounts by the Exchange Ratio of .6389, which would have been the
  applicable Exchange Ratio based on the Average Closing Price for shares of
  Commercial Common Stock as of August 10, 1995 ($31.45) if the Acquisition
  Merger had been consummated as of that date. For information regarding
  adjustment of the Exchange Ratio in the event the Average Closing Price is
  lower than $24.00 or between $24.00 and $27.00 as of the Acquisition Merger
  Effective Time, see "The Merger --Conversion of Railroad Common Stock." The
  purpose of the Railroad pro forma equivalent net income (loss) from continuing
  operations and book value per common share amounts is to show what such per
  share amounts would have equated to for each respective share of Railroad
  Common Stock had the Merger been consummated as of the beginning of the
  periods indicated.     

       Historical information for Commercial and Railroad is derived from the
  respective consolidated financial statements incorporated by reference herein,
  and the pro forma combined information is derived from the pro forma financial
  information elsewhere herein.  The pro forma results might not be indicative
  of the results that would have occurred if the 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 Railroad.

       The Federal Deposit Insurance Corporation Improvement Act of 1991
  established five regulatory capital categories: well-capitalized, adequately-
  capitalized, undercapitalized, significantly undercapitalized and critically
  undercapitalized; and authorized banking regulatory agencies to take prompt
  corrective action with respect to institutions in the three undercapitalized
  categories.  These corrective actions become increasingly more stringent as
  the institution's regulatory capital declines.  At March 31, 1995, the Bank
  and Railroad Savings, on both a historical basis and on an unaudited pro forma
  combined basis as if the Merger had been consummated as of March 31, 1995,
  exceeded the minimum requirements for the well-capitalized category as shown
  in the following table.

Dividends

     Commercial has never paid dividends and Railroad has not paid dividends
since December 15, 1988. The payment of dividends by Commercial and Railroad is
subject to the discretion of each company's Board of Directors and depends on a
variety of factors, including each company's operating results and financial
condition, regulatory limitations, tax considerations and other factors. Under
Delaware law, dividends may be paid in cash, in property or in shares of
Railroad's capital stock either out of Railroad's surplus or, in case there is
no surplus, out of the net profits for the fiscal year in which the dividend is
declared and/or the preceding fiscal year. Under Nebraska law, dividends may be
paid in cash, in property or in shares of Commercial's capital stock only out of
Commercial's unrestricted earned surplus.

     At the present time, the only significant independent sources of funds
available for the payment of dividends by Commercial are dividends paid by the
Bank to Commercial and Commercial's unrestricted liquid assets ($6.6 million
at March 31, 1995), and the only significant sources of funds available for
the payment of dividends by Railroad are dividends paid by Railroad Savings to
Railroad.  Under regulations of the OTS, neither the Bank nor Railroad Savings
is permitted to pay dividends on its capital stock if its regulatory capital
would thereby be reduced below the amount then required for the liquidation
account established for the benefit of certain depositors at the time of its
conversion to stock form.  In addition, the Bank and Railroad Savings are
required to give the OTS 30 days' prior notice of any proposed declaration of
a dividend to Commercial and Railroad, respectively, and are subject to
federal regulations which impose additional limitations on the payment of
dividends and other capital distributions (including stock repurchases and
cash mergers).


                       COMPARISON OF STOCKHOLDER RIGHTS

     Introduction.  Upon consummation of the Merger, holders of Railroad
Common Stock, whose rights are presently governed by Delaware law and
Railroad's certificate of incorporation and bylaws, and indirectly by Railroad
Savings' charter and bylaws, will become stockholders of Commercial, a
Nebraska corporation.  Accordingly, their rights will be governed by the
Nebraska Business Corporation Act and the articles of incorporation and bylaws
of Commercial and indirectly by the Bank's charter and bylaws.  Certain
differences arise from the change in governing law, as well as from
differences between the certificate of incorporation and bylaws of Railroad
and the articles of incorporation and bylaws of Commercial and between the
charter and bylaws of Railroad Savings and the Bank.  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 Delaware General Corporation Law, the
Nebraska Business Corporation Act, the articles of incorporation and bylaws of
Commercial and the certificate of incorporation and bylaws of Railroad.  See
"Available Information."
    
     Issuance of Capital Stock. The articles of incorporation of Commercial
authorize the issuance of 25,000,000 shares of common stock, par value $.01 per
share, and 10,000,000 shares of preferred stock, par value $.01 per share. The
certificate of incorporation of Railroad authorizes the issuance of 4,000,000
shares of common stock, par value $0.10 per share, and 1,000,000 shares of
preferred stock, par value $0.10 per share. At August 10, 1995, 12,910,957 and
2,130,572 shares of Commercial Common Stock and Railroad Common Stock,
respectively, were issued and outstanding. For information regarding the number
of shares of Commercial's common stock that would have been issued on a pro
forma basis upon the consummation of the Acquisition Merger as of that date, see
"Unaudited Pro Forma Combined Financial Information." Under Commercial's
articles of incorporation and Railroad's certificate of incorporation,
Commercial and Railroad are authorized to issue additional shares of capital
stock up to the amount authorized without stockholder approval.

     Payment of Dividends.  The ability of Commercial and Railroad to pay
dividends on their common stock is governed by Nebraska and Delaware corporate
law, respectively.  Under Nebraska corporate law, dividends may be paid in
cash, in property or in shares of Commercial's capital stock.  Additionally,
under Nebraska law, dividends

                                      45
<PAGE>
 
of cash or property may only be paid out of unreserved and unrestricted retained
earnings and no dividends may be paid when a corporation is insolvent or when
the payment of such a dividend would render a corporation insolvent.  Under
Delaware corporate law, dividends may be paid in cash, in property or in
shares of Railroad's capital stock either out of Railroad's surplus (defined
as the excess of the net assets over the stated capital of Railroad) or, in
case there is no surplus, out of the net profits for the fiscal year in which
the dividend is declared and/or the preceding fiscal year.

     The ability of Commercial and Railroad to pay dividends on their common
stock is also affected by restrictions upon their receipt of dividends from
their respective subsidiary savings institutions.  See "Common Stock Prices
and Dividends" for additional information.

     Special Meetings of Stockholders.  Commercial's articles of incorporation
provide that special meetings of stockholders of Commercial may be called by a
majority of the Board of Directors, by the holders of seventy-five percent or
more of the shares entitled to vote at such meeting, or by a duly authorized
committee of the Board of Directors.  Special meetings of the holders of
Railroad's common stock may be called by a majority of the Board of Directors
or by a duly authorized committee of the Board of Directors.

     Number and Term of Directors.   Commercial's Board of Directors consists
of nine persons, divided into three classes.  Under the terms of Commercial's
articles of incorporation, the  number of directors may only be changed by the
affirmative vote of not less than 75.0% 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 in the election of directors and other than "Principal
Shareholders" (as defined in the articles of incorporation).  Railroad's Board
of Directors consists of seven persons, divided into three classes in nearly
equal number as possible.  Railroad's bylaws provide that the number of
directors may be increased by the Board of Directors; however, Railroad's
certificate of incorporation limits the size of the Board to no more than nine
directors.

     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.  Railroad's Certificate of
Incorporation provides that nominations for the election of directors and
proposals for any new business to be taken up at any annual or special meeting
of stockholders may be made by any stockholder of Railroad entitled to vote
generally in the election of directors.  In order to make any such nomination
or proposal, a stockholder must give notice in writing, delivered or mailed to
the Secretary of Railroad, not less than thirty days nor more than sixty days
prior to such meeting, together with certain information relating to the
nomination or proposal.

     Limitations on Acquisitions of Capital Stock.  Nebraska law contains a
control share acquisition statute pursuant to which an acquisition of 20% or
more of Commercial's common stock generally may be made only after (i) a
proposed acquiror submits a statement to Commercial identifying the proposed
acquiror and describing the number of shares owned and proposed to be acquired
and the terms of the proposed acquisition and (ii) the holders of a majority
of the shares entitled to vote which are not interested shares authorize the
proposed acquisition.  Shares acquired in a "control-share acquisition"
(generally, an acquisition, directly or indirectly, by an acquiring person of
ownership of voting stock of a corporation that entitles that person to
exercise or direct the vote of at least 20% but less than 33-1/3%, at least
33-1/3% but less than or equal to 50%, or over 50% of the voting power of the
corporation) have the same voting rights as other shares in the same class or
series in all elections of directors, but have voting rights on all other
matters only to the extent approved by a vote of shareholders at an annual or
special meeting. Delaware law does not contain a control share acquisition
statute and therefore does not contain a similar requirement for stockholder
approval prior to an acquisition of 20% or more of Railroad's common stock.
See " --Approval of Mergers, Consolidations, Sale of Substantially All Assets
and Dissolution" for certain restrictions imposed by Delaware law.

       Approval of Mergers, Consolidations, Sale of Substantially All Assets and
  Dissolution.  Nebraska law generally provides for the merger or consolidation
  of Commercial with another corporation, the sale of all or substantially all
  of Commercial's assets or the dissolution of Commercial upon the approval of
  the holders of at least two-thirds of the outstanding shares.  However, a
  merger or consolidation, or a sale, lease, exchange, mortgage, pledge,
  transfer or other disposition of assets of Commercial having an aggregate
  market value equal to or more than 10% of the market value of the total assets
  of Commercial involving an "interested shareholder" (generally, any person
  entitled to exercise 10% of the voting power of Commercial)  generally would
  be prohibited under Nebraska law for five years after the interested
  shareholder acquired 10% of Commercial's voting power (unless before such
  acquisition Commercial's board of directors approved either the acquisition or
  the proposed transaction).  Delaware law generally provides for the merger or
  consolidation of Railroad with another corporation, the sale of all or
  substantially all of Railroad's assets or the dissolution of Railroad upon the
  approval of the holders of a majority of Railroad's outstanding voting stock.
  However, a merger or consolidation or disposition of assets or securities
  issued by Railroad involving an interested shareholder is generally prohibited
  under Delaware law for three years after the interested shareholder acquired
  15% of Railroad's voting stock, unless either (i) before such acquisition,
  Railroad's board of directors approved either the acquisition or the proposed
  transaction, (ii) upon such acquisition, the interested shareholder owned at
  least 85% of Railroad's voting stock, or (iii) on or after the acquisition
  date, the proposed transaction is approved by Railroad's board of directors
  and the holders of two-thirds of Railroad's outstanding voting stock not owned
  by the interested shareholder.

       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 shareholders 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.

       Railroad's Certificate of Incorporation provides that the affirmative
  vote of the holders of at least 70% of the outstanding shares entitled to
  vote, and at least a majority of the outstanding shares entitled to vote not
  including shares beneficially owned by a "related person" (generally, an
  individual who beneficially owns in the aggregate 10% or more of the
  outstanding common stock of Railroad) is required in order to authorize any
  merger or consolidation with a related person, or any sale, lease, exchange,
  transfer or other disposition of more than 25% of the total assets of Railroad
  to a related person, unless the merger or consolidation or such disposition of
  assets is first approved by a majority of directors who are unaffiliated with
  the related person and who were members of the board of directors prior to the
  time that the related person acquired in the aggregate more than 10% of the
  outstanding common stock of Railroad.

       Dissenters' Rights of Appraisal.  Under the DGCL, stockholders are
  generally entitled to dissent from, and demand payment of the fair value of
  their shares in connection with a plan of merger or consolidation provided
  that shareholder has neither voted in favor of nor consented to such corporate
  action.  A stockholder may not demand the fair value of his  or her stock and
  is bound by the terms of the action if the stock of the corporation is listed
  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 held of record by more than 2,000 shareholders.
  Because Railroad Common Stock is authorized for quotation on the American
  Stock Exchange, Railroad stockholders currently do not have the right to
  demand and receive the fair value of their shares in connection with a plan of
  merger or consolidation.

                                      47

       The Nebraska Business Corporation Act provides in general that
  stockholders of a corporation which is a party to certain extraordinary
  corporate actions, including a merger, consolidation, sale of substantially
  all of the assets of the corporation, and a charter amendment materially and
  adversely affecting stockholder rights have a right to object to such actions
  and to demand and receive the fair value of their shares.  The Nebraska
  Business Corporation Act provides, however, that dissenters' rights of
  appraisal are not available to the stockholders of a bank, trust company,
  stock-owned savings and loan association, industrial loan and investment
  company, or the holding company of any such financial institution.  As
  Commercial is the holding company of a federal savings bank, Commercial's
  stockholders do not have dissenters' rights of appraisal under the Nebraska
  Business Corporation Act.

       Limitations on Directors' Liability.  The Nebraska Business Corporation
  Act does not have a statute which provides for limiting or eliminating the
  liability of directors.  However, Article VI of Commercial's articles of
  incorporation provides that an "outside director" shall not be personally
  liable to Commercial or its stockholders for monetary damages for breach of
  his fiduciary duty as a director and authorizes Commercial to indemnify such
  outside director against monetary damages for such breach to the full extent
  permitted by law.  This provision applies to acts or omissions occurring after
  the effective date of the amendment, and does not limit liability for (i) any
                                                ---                            
  act or omission not in good faith which involves intentional misconduct or a
  knowing violation of law, (ii) any transaction from which the outside director
  derived an improper direct or indirect financial benefit, (iii) paying a
  dividend or approving a stock repurchase in violation of the Nebraska Business
  Corporation Act or (iv) any act or omission which violates a declaratory or
  injunctive order obtained by Commercial or its stockholders.  For purposes of
  Article VI, "outside director" is defined as any member of the Board of
  Directors who is not an officer or a person who may control the conduct of
  Commercial through management agreements, voting trusts, directorships in
  related corporations or any other device or relationship.  There is no similar
  provision in Commercial's articles of incorporation which limits the liability
  of directors who are not "outside directors."

       Under Delaware law, a Delaware corporation may include in its certificate
  of incorporation a provision that eliminates or limits a director's personal
  liability for monetary damages for breach of his or her fiduciary duty,
  subject to certain limitations.  Railroad's certificate of incorporation
  provides that a director shall not be personally liable to Railroad or its
  stockholders for monetary damages arising out of the director's breach of his
  or her duty of care, except to the extent that Delaware law does not permit
  exemption from such liability.  The certificate of incorporation does not
  eliminate the duty of care of directors; instead, it is designed to limit the
  personal liability of directors for monetary damages.  The certificate of
  incorporation does not affect the availability of injunctive or other
  equitable relief as a remedy for breach of the duty of care.  In addition, the
  provision applies only to the personal liability of directors (whether or not
  they are also officers) acting as directors and has no effect on the potential
  liability of individuals for their actions as officers of Railroad.

       Amendment of articles of incorporation, certificate of incorporation and
  bylaws.   Commercial's articles of incorporation may be amended upon the
  approval of two-thirds of Commercial's shareholders.  However, the affirmative
  vote of 75% of all outstanding shares 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 outstanding shares entitled to
  vote generally, other than in the election of directors other than "principal
  shareholders" (as defined in Commercial's articles) are required to alter or
  amend certain provisions in the articles, including provisions which: (i)
  require that there be nine directors; (ii) classify the board into three
  classes with staggered terms; (iii) provide that a director may only be
  removed upon the affirmative vote of 75% of the shares entitled to vote; (iv)
  allow the board of directors to fill vacancies on the board; (v) require a
  supermajority vote to approve certain business combinations with a 20% or
  greater stockholder; (vi) mandate that certain business combinations comply
  with the fair price provisions contained in the articles; (vii) permit the
  stockholders to amend Commercial's bylaws only upon the affirmative vote of
  75% or more of the shares entitled to vote.  Commercial's bylaws may be
  amended either by the board of directors or by the affirmative vote of 75% of
  the outstanding shares of Commercial's stock.  Railroad's certificate of
  incorporation may be amended by a majority of the outstanding shares of its
  voting stock, provided, however, that approval of 70% of the outstanding
  voting stock is required to amend certain provisions of the certificate of
  incorporation, including provisions which:  (i) deny stockholders the power to
  consent in writing

                                      48
<PAGE>
 
  to corporate action; (ii) eliminate the power of stockholders to call special
  meetings; (iii) eliminate cumulative voting; (iv) set out the requirements for
  nominations for the election of directors and proposals for new business; (v)
  set out the number of directors and classify the board into three classes with
  staggered terms (vi) provide that a director may only be removed by the vote
  of 80% of the stockholders; (vii) require approval of 70% of the stockholders
  of certain business combinations with a 10% or greater stockholder; (viii)
  require the board to consider certain factors when evaluating certain business
  combinations; (ix) eliminate the liability of directors to the stockholders in
  certain circumstances; (x) provide for indemnification of directors, officers
  and employees for certain liabilities; and (xi) provide that the directors may
  amend the bylaws and that stockholders may only amend the bylaws upon the
  affirmative vote of 70% or more of the outstanding shares entitled to vote
  generally in the election of directors.  Railroad's bylaws generally may be
  amended either by the Board of Directors or upon the approval of the holders
  of 70% of Railroad's outstanding voting stock.

       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 shareholders
  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's
  outstanding shares of common stock without complying with a procedure intended
  to ensure fair treatment of all shareholders 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.

       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 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 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's 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's 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.

                                      49
<PAGE>
 
       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 one-hundredth of a share of
  Preferred Shares at a price of $42.00 per one 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's 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
  $.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's outstanding common
  stock in a transaction not involving a purchase by Commercial or its
  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's 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.

       Railroad has not issued any similar rights or entered any similar
  agreement with respect to its common stock.

                         ADJOURNMENT OF SPECIAL MEETING
                         (Proposal 2 - Special Meeting)
       
       In the event that there are not sufficient votes to approve the
  Acquisition Merger and the Merger Agreement at the time of the Special
  Meeting, such proposal could not be approved unless the Special Meeting were
  adjourned in order to permit further solicitation of proxies.  In order to
  allow proxies that have been received by Railroad at the time of the Special
  Meeting to be voted for such adjournment, if necessary, Railroad has submitted
  the question of adjournment under such circumstances to its stockholders as a
  separate matter for their consideration.  A majority of the shares represented
  and voting at the Special Meeting is required in order to approve any such
  adjournment.  The Board of Directors of Railroad recommends that stockholders
  vote their proxies in favor of such adjournment so that their proxies may be
  used for such purpose in the event it should become necessary.  Properly
  executed proxies will be voted in favor of any such adjournment unless
  otherwise indicated thereon. Abstentions and broker non-votes will not be
  voted in favor of this proposal. If it is necessary to adjourn the Special
  Meeting, no notice of the time and place of the adjourned meeting is required
  to be given to stockholders other than an announcement of such time and place
  at the Special Meeting.      

       Railroad's Board of Directors unanimously recommends that stockholders
  vote FOR the proposal to adjourn the Special Meeting if necessary to permit
  further solicitation of proxies.

                             STOCKHOLDER PROPOSALS

       If the Merger is not consummated, Railroad is expected to retain its
  December 31 fiscal year end.  In such event, in order to be eligible for
  inclusion in Railroad's proxy solicitation materials for its 1996 annual
  meeting of stockholders, any stockholder proposal to take action at such
  meeting is required to be received at Railroad's home office at 110 South Main
  Street, Suite 900, Wichita, Kansas 67202, no later than November 20, 1995.
  Any such proposal would be subject to the requirements of the proxy rules
  adopted under the Exchange Act.

                                 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, Omaha, Nebraska.

       Certain other legal matters in connection with the Merger will be passed
  upon for Commercial by Housley Goldberg Kantarian & Bronstein, P.C.,
  Washington, D.C., and for Railroad by Thompson & Mitchell, St. Louis,
  Missouri.

                      REORGANIZATION AND MERGER AGREEMENT
       =================================================================

     THIS REORGANIZATION AND MERGER AGREEMENT ("Agreement") is dated as of April
18, 1995, by and among COMMERCIAL FEDERAL CORPORATION, a Nebraska corporation
("Commercial") and COMMERCIAL FEDERAL BANK, A FEDERAL SAVINGS BANK, a Federal-
chartered savings bank and wholly-owned subsidiary of Commercial ("Bank"); and
RAILROAD FINANCIAL CORPORATION, a Delaware corporation ("Company") and  RAILROAD
SAVINGS BANK, FSB, a Federal-chartered savings bank and wholly-owned subsidiary
of Company ("Savings").

     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 Bank, with its principal offices in Omaha,
Nebraska;

     WHEREAS, Company, a non-diversified, unitary savings and loan holding
company, with principal offices in Wichita, Kansas, owns all of the issued and
outstanding capital stock of Savings, with  principal offices in Wichita,
Kansas;

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

     WHEREAS, following the combination of Commercial and Company it is intended
that Bank and Savings will be merged such that the resulting holding company
will retain the advantage of a unitary savings and loan holding company status
and that the resulting savings institution will achieve certain economies of
scale and efficiencies as a result of such subsequent merger and expand its
market area.

     WHEREAS, it is intended that to accomplish this result, the Company will be
acquired by means of a merger (the "Acquisition Merger") of the Company with and
into Commercial, followed by the merger of Savings with and into Bank (the "Bank
Merger").  The Acquisition Merger and the Bank Merger are collectively referred
to as the "Merger".

     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.

                                       1

     WHEREAS, as an inducement to and condition of Commercial's willingness to
enter into this Agreement, the Company will grant to Commercial an option
pursuant to the Stock Option Agreement, the form of which is attached hereto as
Exhibit 1.14.

     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
and the Stock Option Agreement.  Consummation of the Merger is subject to the
prior approval of the Office of Thrift Supervision ("OTS") and the stockholders
of the Company, among other conditions specified herein.

     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:

                (i)  Each outstanding share of Company common stock issued and
outstanding at the Acquisition Merger Effective Time, except as provided in

                                       3
<PAGE>
 
                     (A)  If the Average NMS Closing Price (as defined below)
shall be equal to or greater than $24.00 but equal to or less than $27.00, then
the Exchange Ratio shall be such number of shares of Commercial common stock
equal to the quotient (carried to four digits) that results by dividing $17.25
by the Average NMS Closing Price of Commercial common stock (a maximum of .7188
and a minimum of .6389 shares of Commercial common stock);

                     (B)  If the Average NMS Closing Price shall be greater than
$27.00, then the Exchange Ratio shall be .6389 shares of Commercial common
stock;

                     (C) If the Average NMS Closing Price shall be less than
$24.00, then the Exchange Ratio shall be .7188 shares of Commercial common
stock; provided, however, in the event the Exchange Ratio is adjusted pursuant
to the proviso contained in Section 5.4(f) hereof the Exchange Ratio shall be
the Exchange Ratio as so adjusted.

                (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

capacity) at the Acquisition Merger Effective Time shall cease to exist, and the

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 on the Acquisition
Merger Effective Time for Company common stock or kind of securities of
Commercial shall be proportionately adjusted to take into account such Stock
Adjustment. In addition, the Average NMS Closing Price amounts set forth above
shall be proportionately adjusted to compensate for any such Stock Adjustment.

                                       4

Dealers, Inc. (the "National Market System") (or at the close of the trading day
by such other national securities exchange).  The term "Average NMS Closing
Price" shall mean the arithmetic mean of the NMS Closing Prices for the twenty-
fifth through the sixth trading day, inclusive, immediately preceding the

Surviving Corporation as the Surviving Corporation.

          (c)  The bylaws of Commercial, together with all amendments thereto,
if any, as in effect immediately prior to the Acquisition Merger Effective Time,
shall thereafter be the bylaws of the Surviving Corporation, until amended as
provided therein or by law.

          (d)  The directors and officers of Commercial in office immediately
prior to the Acquisition Merger Effective Time shall be the directors and
officers of the Surviving Corporation following the Acquisition Merger, until

          (e)  From and after the Acquisition Merger Effective Time:

                (i)    The Surviving Corporation shall possess all assets and
property of every description, and every interest in the assets and property,
wherever located, and the rights, privileges, immunities, powers, franchises,
and authority, of a public as well as of a private nature, of each of Commercial
and the Company, and all obligations belonging or due to each of Commercial and
Company, 

                                       5
<PAGE>
 
all of which are vested in the Surviving Corporation without further act or

Commercial or the Company shall not revert or in any way be impaired by reason
of the Acquisition Merger.

                (ii)   The Surviving Corporation is liable for all the
obligations of each of Commercial and the Company. Any claim existing, or action
or proceeding pending, by or against the Company or Commercial, may be

                (iii)  All the rights of creditors of each of the Company and
Commercial are preserved unimpaired, and all liens upon the property of the
Company and Commercial are preserved unimpaired, on only the property affected
by such liens immediately prior to the Acquisition Merger Effective Time.

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

          (a)  Commercial has reserved 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.

          (b)  After the Acquisition Merger Effective Time, holders of
certificates theretofore evidencing outstanding shares of Company common stock
(other than as provided in Section 1.3(a)(ii), upon surrender of such
certificates to an exchange agent appointed by Commercial (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 provided in Section 1.3 hereof, and 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 Commercial common stock 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.

                                       6
<PAGE>
 
          (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 shares cancelled at the Acquisition
Merger Effective Time pursuant to Section 1.3(a)(ii) 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 paid to such
holder, and which dividends or distribution had a record date occurring on or
subsequent to the Acquisition Merger Effective Time and the amount of any cash,
without interest, payable to such holder 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 as
herein provided.

          (d)  All shares of Commercial common stock and cash for 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 

                                       7
<PAGE>
 
certificate, upon the making of an affidavit of that fact by the holder thereof,
such shares of Commercial common stock and cash for 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 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 NMS Closing
Price.  For the purposes of determining any such fractional share interests, all
shares of Company common stock owned by a Company shareholder shall be combined
so as to calculate the maximum number of whole shares of Company common stock
issuable to such Company shareholder.

     1.7  Shareholders' Meeting.  The Company shall, at the earliest practicable
          ---------------------                                                 
date, hold a meeting of its shareholders (the "Company Shareholders' Meeting")
to submit for shareholder approval this Agreement and the Acquisition Merger.
The affirmative vote of the holders of a majority of the issued and outstanding
shares of Company common stock entitled to vote shall be required for such
approval.

     1.8  Company Stock Options.
          --------------------- 

          (a)  At the Acquisition Merger Effective Time, each outstanding option
under the Company's 1994 Stock Option and Incentive Plan, the 1986 Stock Option
and Incentive Plan and the 1991 Director's Stock Option Plan (the "Company
Option Plans") shall continue outstanding as an option to purchase, in place of
the purchase of each share of Company common stock, the number of shares
(rounded down to the nearest whole share) of Commercial common stock that would
have been received by the optionee in the Merger had the option been exercised
in full (without regard to any 

                                       8
<PAGE>
 
limitations contained therein on exercise) for shares of Company common stock
immediately prior to the Acquisition Merger upon the same terms and conditions
under the relevant option as were applicable immediately prior to the
Acquisition Merger Effective Time, except for appropriate pro rata adjustments
as to the relevant option price for shares of Commercial common stock
substituted therefor so that the aggregate option exercise price of shares
subject to an option immediately following the assumption and substitution shall
be the same as the aggregate option exercise price for such shares immediately
prior to such assumption and substitution. It is intended that the foregoing
assumption shall be undertaken consistent with and in a manner that will not
constitute a "modification" under Section 424 of the Code as to any stock option
which is an "incentive stock option." Commercial and Company agree to take such
actions as shall be necessary to give effect to the foregoing.

          (b)  At all times after the Acquisition Merger Effective Time,
Commercial shall reserve for issuance such number of shares of Commercial common
stock as necessary so as to permit the exercise of options granted under the
Company's Option Plans in the manner contemplated by this Agreement and the
instruments pursuant to which such options were granted.  Commercial shall make
all filings required under federal and state securities laws so as to permit the
exercise of such options and the sale of the shares received by the optionee
upon such exercise.

     1.9  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 holding the Company Shareholders' Meeting,
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 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,
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 Statement, insofar as it
relates to such corporations, to comply with Section 1.9(a) hereof. Commercial
agrees promptly to advise the Company if at any time prior to the Company
Shareholders' 

                                       9
<PAGE>
 
Meeting 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 1.9(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 1.9(a)
hereof.  The Company agrees promptly to advise Commercial if at any time prior
to the Company Shareholders' Meeting 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 1.9(a).

          (d)  Commercial shall promptly 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. Commercial shall advise the
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. Commercial and the Company each shall
take such action as may be necessary or appropriate to ensure that their
respective affiliated persons are aware of and comply with the guidelines of the

SEC staff accounting bulletin series. All shares of Commercial common stock
issued to such Company affiliated persons (i) in connection with the Merger or
(ii) upon exercise of options received pursuant to Section 1.8 hereof subsequent
to the Acquisition Merger Effective Time, 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/or pooling of interests accounting requirements,
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 three 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 three 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.

                                   ARTICLE II
             REPRESENTATIONS AND WARRANTIES OF COMPANY AND SAVINGS

     Company and Savings represent and warrant to Commercial and the Bank that,
except as disclosed in Schedule I attached hereto:

     2.1  Organization, Good Standing, Authority, Insurance, Etc.  The Company
          ------------------------------------------------------              
is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware.  Section 2.1 of Schedule I lists each
"subsidiary" of the Company and Savings within the meaning of Section
10(a)(1)(G) of HOLA, (individually a "Company Subsidiary" and collectively the
"Company Subsidiaries") (unless otherwise noted herein all references to a
"Company Subsidiary" or to the "Company Subsidiaries" shall include Savings).
Each of the Company Subsidiaries 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 of Schedule I.  The Company and each
Company Subsidiary has all requisite power and authority and is duly qualified
and licensed to own, lease and operate its properties and conduct its business
as it is now being conducted.  The Company has delivered to Commercial a true,
complete and correct copy of the certificate of incorporation, charter, or other
organizing document and of the bylaws, as in 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 is necessary under
applicable law, except to the extent that any failures to so qualify would not,
in the aggregate, 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.  Savings is a member in good standing of the Federal Home Loan
Bank of Topeka and all eligible accounts issued by Savings are insured by the
Savings Association Insurance Fund ("SAIF") to the maximum extent permitted
under applicable law.  Savings is a "domestic building and loan association" as
defined in Section 7701(a)(19) of the Code and is a "qualified thrift lender" as
defined in Section 10(m) of the HOLA and the Thrift Regulations.  The Company is
duly registered as a savings and loan holding company under the HOLA.

     The minute books of the Company and the Company's Subsidiaries contain
complete and accurate records of all meetings and other corporate actions held
or taken of their respective shareholders and Boards of Directors (including the
committees of such Boards).

     2.2  Capitalization.  The authorized capital stock of the Company consists
          --------------                                                       
of (i) 4,000,000 shares of common stock, par value $0.10 per share, of which
2,116,074 shares were issued and outstanding as of the date of this Agreement,
and (ii) 1,000,000 shares of preferred stock, par value of $0.10 per share, of
which no shares were outstanding as of the date of this Agreement. All

                                      13
<PAGE>
 
outstanding shares of Company common stock are duly authorized, validly issued,
fully paid, nonassessable and free of preemptive rights. Except for outstanding
options to purchase 146,309 shares of Company common stock under the Company
Option Plans and as contemplated by the Option Agreement, as of the date of this
Agreement, 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 (collectively, "Stock
Contract") to which the Company or any of its affiliates is subject with respect
to the issuance, voting or sale of issued or unissued shares of the Company's
capital stock. A true and complete copy of the Company's Option Plans, as in
effect on the date of this Agreement, is attached as Section 2.2 of Schedule I.
Neither the Company nor Savings is aware of any event or circumstance (but not
including actions or events by Commercial) which would disqualify the Merger
from being accounted for as a pooling of interests.
 
     2.3  Ownership of Subsidiaries.  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 of any lien, claim, charge, restriction or encumbrance (collectively,
"Encumbrance").  Except as set forth in Section 2.3 of Schedule I, all of the
outstanding capital stock or other ownership interests in all of the Company
Subsidiaries is owned either by the Company or Savings.  There are no options,
convertible securities, warrants, or other rights (preemptive or otherwise) to
purchase or acquire any capital stock of any Company Subsidiary and no contracts
to which the Company or any of its affiliates is subject with respect to the
issuance, voting or sale of issued or unissued shares of the capital stock of
any of the Company Subsidiaries.  Neither the Company nor any Company Subsidiary
owns any of the capital stock or other equity securities (including securities
convertible or exchangeable into such securities) of or profit participations in
any "company" (as defined in Section 10(a)(1)(C) of the HOLA) other than the
Federal Home Loan Bank of Topeka or except as set forth in Section 2.3 of
Schedule I.

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

          (a)  No registration statement, proxy statement, schedule or report
filed by the Company or any Company Subsidiary with the SEC or the OTS under the
1933 Act or the 1934 Act ("SEC Reports"), 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 

                                      14
<PAGE>
 
past five years, the Company and the Company Subsidiaries have timely filed all
reports and documents required to be filed by them with the SEC, the OTS, or the
Federal Deposit Insurance Corporation (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 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, 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, 1994) in accordance
with the Company'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, 1994, will present) fairly the consolidated balance
sheet and the consolidated statements of operations, stockholders' equity and
cash flows of the Company and its 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 audited consolidated
financial statements of the Company at December 31, 1994 and for the year 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. 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, 1994 or for transactions effected or actions occurring or omitted to be
taken after December 31, 1994 (i) in the ordinary course of business, or (ii) as
permitted by this Agreement.

          (b)  The Company has delivered to Commercial each SEC Report filed,
used or circulated by it with respect to periods 

                                      15
<PAGE>
 
since January 1, 1992 through the date of this Agreement and will promptly
deliver each such SEC Report filed, used or circulated after the date hereof,
each in the form (including exhibits and any amendments thereto) filed with the
SEC or the OTS (or, if not so filed, in the form used or circulated), including,
without limitation, its Annual Reports on Form 10-K and its Quarterly Reports on
Form 10-Q.

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, 1994, each of the Company and the Company Subsidiaries has owned and
operated their respective assets, properties and businesses in the ordinary
course of business and consistent with past practice.

          --------------------------                                    
Statement is mailed to the shareholders of the Company for the solicitation of
proxies for the approvals referred to in Section 1.7(a) hereof and at all times
subsequent to such mailings up to and including the times of such approval, such
Prospectus/Proxy Statement (including any supplements thereto), with respect to
all information set forth therein relating to the Company (including the Company
Subsidiaries), its shareholders and representatives, Company common stock and
all other transactions contemplated hereby, will:

          (a)  Comply in all material respects with applicable provisions of the
1933 Act, the 1934 Act and the rules and regulations under such Acts; and

          (b)  Not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements contained therein, in light of the circumstances under which

          ----------------------------                                       
person or firm acting on behalf or under authority of the Company or any of the
Company Subsidiaries is or will be entitled to any broker's or finder's fee or
any other commission or similar fee directly or indirectly in connection with
the Merger or any other transaction contemplated hereby, except the

<PAGE>
 
applicable state takeover laws, (ii) any Delaware laws limiting or restricting

Schedule I, there are no employment, severance or other 

                                      18
<PAGE>
 
agreements, plans or arrangements with any current or former directors, officers
or employees of Company or any Company Subsidiary which may not be terminated
without penalty (including any augmentation or acceleration of benefits) on 30
days or less notice to such person. No payments to directors, officers or
employees of the Company or the Company Subsidiaries resulting from the
transactions contemplated hereby will cause the imposition of excise taxes under
Section 4999 of the Code or the disallowance of a deduction to the Company or
any Company Subsidiary pursuant to Section 280G(a) of the Code.

     2.13  Employee Benefits.
           ----------------- 

          (a)  Neither the Company nor any of the Company Subsidiaries maintains
any funded deferred compensation plans (including profit sharing, pension,
savings or stock bonus plans), unfunded deferred compensation arrangements or
employee benefit plans as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), other than any plans
("Employee Plans") set forth in Section 2.13 of Schedule I (true and correct
copies of which have been delivered to Commercial).  None of Company or any of
the Company Subsidiaries has incurred or reasonably expects to incur any
liability to the Pension Benefit Guaranty Corporation except for required
premium payments which, to the extent due and payable, have been paid.  The
Employee Plans intended to be qualified under Section 401(a) of the Code are so
qualified, and Company is not aware of any fact which would adversely affect the
qualified status of such plans.  Except as set forth in Section 2.13 of Schedule
I, neither the Company nor any of the Company Subsidiaries (a) provides health,
medical, death or survivor benefits to any former employee or beneficiary
thereof, or (b) maintains any form of current (exclusive of base salary and base
wages) or deferred compensation, bonus, stock option, stock appreciation right,
benefit, severance pay, retirement, incentive, group or individual health
insurance, welfare or similar plan or arrangement for the benefit of any single
or class of directors, officers or employees, whether active or retired
(collectively "Benefit Arrangements").

          (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 1994 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, 1994.

          (c)  To the best knowledge of the Company, with respect to all
Employee Plans and Benefit Arrangements, the Company and each Company Subsidiary
are in substantial compliance with the requirements prescribed by any and all
statutes, governmental or court orders, or rules or regulations currently in
effect, 

                                      19
<PAGE>
 
including but not limited to ERISA and the Code, applicable to such Employee
Plans or Benefit Arrangements. 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 which could
have an adverse effect on the business, assets, financial condition, results of
operations or prospects of Company or any Company Subsidiary; nor to the best
knowledge of Company 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. To the best of its knowledge, 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 Effective Time of the
Merger.

     2.14  Information Furnished.  No statement contained in any schedule,

date of this Agreement) or to be furnished in writing by or on behalf of Company
to Commercial pursuant to this Agreement or pursuant to the due diligence to be

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

provisions for loan and real estate owned losses as may be necessary in the sole
determination of Commercial to conform the Company's and Savings' loan and real
estate owned allowance practices and methods to those of Commercial and the Bank

after the Acquisition Merger Effective Time); provided, however, that Company
and Savings shall not be required to take such action until: (i) Company and

Reliance Certificate, provide the Company and Savings a written waiver of any
right either entity may have to terminate the Agreement which waiver shall
contain an express condition precedent that Company and Savings have established
such additional provisions for loan and real estate losses as requested by
Commercial pursuant to this Section 4.13. No additional provision for loan and
real estate owned losses taken by Savings pursuant to this Section 4.13 shall be

for a period of three years from the Acquisition Merger Effective Time by the
directors' and officers' liability insurance policy maintained by the Company

Commercial, provided, however, that (i) Commercial's right to terminate this
            --------  ------- 
Agreement due to failure of the condition set forth in Section 5.2(l) shall
expire unless exercised by Commercial on or prior to August 16, 1995; and (ii)
the right to terminate under this Section 5.4(c) shall not be available to
Commercial where Commercial's or Bank's failure to perform an obligation
hereunder has been the cause of, or has resulted in, the failure of the Closing

                -----------------------------------------                      
delivery of written notice of termination to Commercial if any event occurs
which renders impossible of satisfaction in any material respect one or more of
the conditions to the obligations of Company and Savings to effect the Merger

provided, however, that the right to terminate under this Section 5.4(d) shall

                -----------------------------------------

review of the Company Disclosure Schedule (Schedule I) and any documents or
information set forth or disclosed therein) to be conducted pursuant to Section
4.11 herein.

          (f)   Average NMS Closing Price.  By the Company at any time during

                (i)   the Average NMS Closing Price shall be less than $20.00
(adjusted as indicated below in this Section 5.4(f)); and

                (ii)  (A) the number obtained by dividing the Average NMS
Closing Price by the Starting Price shall be less than (B) the number obtained
by dividing the Index Price on the last day of the Determination Period by the
Index Price on the Starting Date and subtracting 0.15 from the quotient in this
clause (ii)(B);

subject, however, to the following three sentences. If the Company elects to
exercise its termination right pursuant to this Section 

                                      42
<PAGE>
 
5.4(f), 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
number (calculated to four digits) obtained by dividing (A) $14.38 by (B) the
Average NMS 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(f) and
this Agreement shall remain in effect in accordance with its terms (except as
the Exchange Ratio shall have been so modified).

     For purposes of this Section 5.4, the following terms shall have the
meanings indicated:

          "Average NMS Closing Price" shall have the meaning specified in
Section 1.3(b).

          "Determination Period" shall have the meaning specified in Section
1.3(b).

          "Index Group" means the financial institutions listed on the SNL
Midwest Thrift Index, as published by SNL Securities LP, and as to which there
shall not have been a publicly announced proposal since the Starting Date and
before the Determination Date for any such company on such list. In the event
that the common stock of any such company ceases to be publicly traded or a
proposal to acquire any such company is announced after the Starting Date and
before the Determination Date, such company will be removed from the Index
Group, and the weights attributed to the remaining companies will be adjusted
proportionately for purposes of determining the Index Price.

          "Index Price," on a given date, means the weighted average of the
closing prices on such dates of the common stocks of the companies comprising
the Index Group.

          "Starting Date" means the last trading day immediately preceding the
date of the first public announcement of entry into this Agreement or, if no
trades of Commercial common stock occur on such day then the date most
immediately preceding such day in which a trade of Commercial common stock
occurred.
 
          "Starting Price" means the closing price per share of Commercial
common stock, as reported on the National Market System (as reported by The Wall
Street Journal or, if not reported thereby, another authoritative source) for
the Starting Date or, if no trades of Commercial common stock occur on such day
then the 

                                      43
<PAGE>
 
date most immediately preceding such day in which a trade of Commercial common
stock occurred.

     If Commercial or any company belonging to the Index Group declares or
effects a stock dividend, reclassification, recapitalization, split-up,
combination, exchange of shares or similar transaction between the Starting Date
and the Determination Date, the prices for the common stock of such company
shall be appropriately adjusted for the purposes of applying this Section
5.4(f).

The Board of Directors
Railroad Financial Corporation
110 S. Main Street, Suite 900
Wichita, KS  67202

Members of the Board:

In connection with the proposed merger transaction (the "Merger") pursuant to a
Reorganization and Merger Agreement to be dated April 18, 1995 (the
"Agreement"), whereby Railroad Financial Corp. ("Railroad") shall be merged with
and into Commercial Federal Corporation ("Commercial Federal") you have
requested our opinion as to the fairness, from a financial point of view, to the
holders (the "Shareholders") of Railroad's common stock of the consideration to
be received in the Merger.  Pursuant to the Agreement, the consideration to be
received by the Shareholders will consist of Commercial Federal common stock to
be issued in a transaction which we have been advised by management of the
parties will be accounted for as a pooling of interests transaction.

Piper Jaffray Inc. ("Piper Jaffray"), as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, underwriting and secondary
distributions of securities, private placements and valuations for estate,
corporate and other purposes.  We make a market in Railroad and Commercial
Federal common stock and public debt securities and provide research coverage on
Railroad and Commercial Federal.  We acted as a manager of a public offering of
Railroad senior notes in 1992 and as a lead manager of a public offering of
Commercial Federal subordinated notes in 1992.  For our services in rendering
this opinion, Railroad will pay Piper Jaffray a fee which is not contingent upon
the consummation of the Merger.  Railroad will also indemnify Piper Jaffray
against certain liabilities in connection with its engagement.

In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances.  Among
other things, we have reviewed a draft of the Agreement dated April 14, 1995,
audited consolidated financial statements for Railroad for the five years ended
December 31, 1994, unaudited consolidated financial statements for Railroad for
the three month period ended March 31, 1995, audited consolidated financial
statements for Commercial Federal for the five years ended June 30, 1994,
unaudited consolidated financial statements for Commercial Federal for the
three, six and eight month periods ended September 30, 1994, December 31, 1994
and February 28, 1995, respectively, certain internal financial planning
information of Railroad prepared by its management, certain publicly available
information relative to Railroad and Commercial Federal,
<PAGE>
 
Railroad Financial Corporation

Page 2


certain other financial and securities data of Railroad and Commercial Federal,
certain financial and securities data of companies deemed similar to Railroad
and Commercial Federal or representative of the business sectors in which they
operate, and the financial terms, to the extent publicly available, of certain
merger transactions.  We have had discussions regarding the financial condition,
current operating results, business outlook and prospects for Railroad and
Commercial Federal with members of their respective managements.

We have relied upon and assumed the accuracy, completeness and fairness of the
financial statements and other information provided by Railroad and Commercial
Federal or otherwise made available to us and have not attempted independently
to verify such information.  We have further relied upon the assurances of
Railroad and Commercial Federal management that the information provided has
been prepared on a reasonable basis and, with respect to financial planning
data, reflects the best currently available estimates, and that Railroad and
Commercial Federal management are not aware of any information or facts that
would make the information provided to us incomplete or misleading.

In arriving at our opinion, we have not performed any appraisals or valuations
of specific assets of Railroad and Commercial Federal, and we express no opinion
regarding the liquidation value of any entity.  We have not been authorized by
the Board of Directors of Railroad to solicit, and did not solicit, other
entities for purposes of a business combination with Railroad.

This opinion is based upon the information available to us and facts and
circumstances as they exist and are subject to evaluation on the date hereof.
We are not expressing any opinion herein as to the prices at which shares of
Railroad common stock or Commercial Federal common stock have traded or at which
such shares might trade at any future time.
    
This opinion is directed to the Railroad Board of Directors and, except with
respect to the inclusion of this opinion in the proxy statement/prospectus to be
used in connection with the Special Meeting of Shareholders of Railroad, to
which we hereby consent, shall not be published or otherwise used, nor shall any
public references to us be made, without our written consent. This opinion is
not intended to be and does not constitute a recommendation to any Shareholder
as to how such Shareholder should vote with respect to the Merger. You have not
requested that we opine as to, and this opinion does not address your
underlying business decision to proceed with or effect the Merger.

Based upon and subject to the foregoing and based upon such other factors as we
consider relevant, it is our opinion that the consideration to be received by
the Shareholders pursuant to the Agreement is fair, from a financial point of
view, to the Shareholders as of the date hereof.

Sincerely,

PIPER JAFFRAY INC.

                            STOCK OPTION AGREEMENT

       This STOCK OPTION AGREEMENT dated as of April 18, 1995 between Commercial
Federal Corporation, a Nebraska Corporation ("Commercial"), and Railroad
Financial Corporation, a Delaware Corporation ("Company").

                                  WITNESSETH:

       WHEREAS, the Boards of Directors of Commercial and Company have approved
a Reorganization and Merger Agreement (the "Merger Agreement"), dated as of
April 18, 1995, between Commercial and its wholly owned subsidiary, Commercial
Federal Bank, A Federal Savings Bank ("Bank"), and Company and its wholly owned
subsidiary, Railroad Savings Bank, FSB ("Savings"), providing for the
acquisition of the Company by Commercial (the "Acquisition Merger") followed by
the merger of Savings with and into the Bank (the "Bank Merger"). The Merger
Agreement is being executed by the parties simultaneously with this Agreement;

       WHEREAS, as a condition to Commercial's entry into the Merger Agreement
and in consideration of such entry, the Company has agreed to grant to
Commercial the option set forth herein;

       NOW THEREFORE, in consideration of the premises herein contained, the
parties agree as follows:

       1.    DEFINITIONS.  Capitalized terms defined in the Merger Agreement and
used herein shall have the same meaning as in the Merger Agreement.

       2.    GRANT OF OPTION.  The Company hereby grants to Commercial an
unconditional, irrevocable option (the "Option"), to be exercised in whole or in
part from time to time as provided herein, to purchase shares of authorized and
unissued or treasury shares of Company's common stock in an amount equal to
13.0% of the shares of Company common stock to be outstanding upon exercise of
the Option at a price of $11.875 per share payable in cash as provided in
Section 4 hereof; provided, however, in the event the Company issues or agrees
to issue any shares of common stock (other than as permitted under the Merger
Agreement) at a price less than $11.875 per share (as adjusted pursuant to
Section 6 herein) such price shall be equal to such lesser price (such price, as
adjusted if applicable, the "Option Price"); and provided further, that such
number of shares shall be reduced by the number of shares, if any, beneficially
owned by Commercial as of the date of exercise.  The number of shares of Company
common stock subject to option hereunder shall also be subject to adjustment as
provided in Section 6 herein.

       3.    EXERCISE OF OPTION.  (a) Subject to compliance with applicable law
and regulation, the Option may be exercised, in whole or part, at any time or
from time to time only upon or after the occurrence of a Purchase Event. As used
herein, "Purchase Event" shall mean when:

                                       1
<PAGE>
 
       (i)   the Company or Savings shall have entered into an agreement with a
       person (other than Commercial or any of its affiliates) to (a) merge or
       consolidate with, or enter into any similar transaction with, the Company
       or Savings, (b) purchase, lease or otherwise acquire all or substantially
       all of the assets of the Company or Savings, or (c) purchase or otherwise
       acquire (including by way of merger, consolidation, share exchange or any
       similar transaction) securities representing 10 percent or more of the
       voting power of the Company or Savings; or

       (ii)  any person (other than Commercial or its affiliates) shall have
       acquired beneficial ownership of 25% or more of the outstanding shares of
       the Company's common stock or shall have merged, consolidated with or
       entered into a similar transaction with the Company or any of the Company
       Subsidiaries or shall have purchased, leased or otherwise acquired all or
       substantially all of the Company's or any Company Subsidiary's assets.

       The Company shall notify Commercial promptly in writing of the occurrence
of any transaction or event which constitutes a Purchase Event.  If more than
one of the transactions, offers or events giving rise to a Purchase Event under
this subsection (a) is undertaken or effected by the same person or occurs at
the same time, then all such transactions and events shall give rise only to one
Purchase Event, which Purchase Event shall be deemed continuing for all purposes
hereof until all such transactions are terminated or abandoned by such person
and all such events have ceased or ended.  As used in this Section 3(a),
"person" shall have the meaning specified in Section 3(a)(9), and "beneficial
ownership" shall have the meaning specified in Section 13(d)(3), of the
Securities Exchange Act of 1934.

       (b)   To exercise the Option, Commercial or its transferee(s) shall send
to the Company a written notice (an "Exercise Notice," the date of which is
herein referred to as the "Notice Date") specifying (i) the total number of
shares it will purchase pursuant to such exercise, and (ii) a place and date not
earlier than three business days nor later than 20 business days from the Notice
Date for the closing of such purchase with respect to such exercise (the "Option
Closing Date"); provided that if prior notification to or approval of any
federal or state regulatory agency is required in connection with such purchase,
Commercial, or its transferee(s), and the Company shall promptly file the
required notice or application for approval and expeditiously process the same,
and the period of time that otherwise would run pursuant to this sentence shall
run instead from the date on which the last required notification period has
expired or been terminated or such approvals have been obtained and any
requisite waiting periods shall have passed. Any exercise of the Option shall be
deemed to occur on the Notice Date relating thereto.

       (c)   The Option shall expire and terminate, to the extent not previously
exercised, upon the earlier of:

             (i)   the Acquisition Merger Effective Time;

                                       2
<PAGE>
 
             (ii)  the date on which the Merger Agreement is terminated (other
       than a termination based upon (A) a willful breach by the Company or
       Savings of any of its or their covenants or agreements provided under the
       Merger Agreement or (B) the failure of the Company or Savings to obtain
       shareholder approval of the transactions contemplated by the Merger
       Agreement) if prior thereto a Purchase Event or a Proposal (as
       hereinafter defined) has not occurred or has not been made;
     
             (iii) 18 months after the later of (A) the occurrence of a Purchase
       Event or (B) the making of a Proposal (as hereinafter defined); provided,
       however, if a Proposal shall be made (during the term of this Agreement)
       prior to the occurrence of a Purchase Event and subsequent thereto a
       Purchase Event occurs then this Option shall be further extended to
       expire upon the expiration of 12 months from the date of occurrence of
       such Purchase Event;
     
             (iv)  18 months after the termination of the Merger Agreement for
       the reasons set forth in clauses (A) and (B) in the parenthetical portion
       of Section 3(c)(ii) herein; or
     
             (v)   such other dates as to which the holders of the Option and
       the Company shall agree.
     
       For purposes of this Agreement, a "Proposal" means a proposal by any
person (other than Commercial or its affiliates), by public announcement or
written communication, or in any application to any federal or state regulatory
authority, to (a) acquire, merge, consolidate with, or enter into any similar
transactions with the Company or Savings, (b) purchase, lease or otherwise
acquire all or substantially all of the assets of the Company or Savings, or (c)
purchase or otherwise acquire (including by way of merger, consolidation, share
exchange or any similar transaction) securities representing more than 15% of
the voting power of the Company.

       Notwithstanding the foregoing, if a holder of all or part of the Option
provides the Company with an Exercise Notice relating to all or part of the
shares of the Company common stock covered by the Option, the Company tenders
performance of its obligations hereunder on the Option Closing Date specified
therein but such holder fails to tender performance of its obligations hereunder
on such Option Closing Date, then the portion of the Option to be exercised by
such holder on such Option Closing Date as specified in the Exercise Notice
shall expire and terminate effective at 5:00 p.m., Eastern time on such Option
Closing Date.

       4.    PAYMENT AND DELIVERY OF CERTIFICATES.  (a) At the closing referred
to in Section 3 hereof, Commercial, or its transferee(s), shall pay to the
Company the aggregate purchase price for the shares purchased pursuant to the
exercise of the Option in immediately available funds by a write transfer to a
financial institution designated by the Company. Commercial, or its
transferee(s), shall pay all transfer taxes imposed by virtue of the assignment
of the Option or such portion to it. Any other transfer taxes shall be paid by
the Company.

                                       3
<PAGE>
 
       (b)   At any closing relating to an exercise of the Option,
simultaneously with the delivery of cash by Commercial, or its transferee(s), as
provided in subsection (a) with respect to the Option, the Company shall deliver
to Commercial, or its transferee(s), a certificate or certificates representing
the number of shares purchased by Commercial, or its transferee(s) and, if the
Option should be exercised in part only, a new Option evidencing the rights of
Commercial or any subsequent transferee(s) thereof to purchase the balance of
the shares purchasable hereunder.

       Commercial acknowledges that the certificates evidencing such stock shall
bear the following legend:

             "The transfer of the shares represented by this
             certificate is subject to resale restrictions arising
             under the Securities Act of 1933, as amended, and certain
             provisions of an agreement between the registered holder
             hereof and the Company, a copy of which agreement is on
             file at the principal office of the Company. A copy of
             such agreement will be provided without charge to the
             holder hereof upon receipt by the Company of a written
             request."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act") in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if Commercial or any subsequent transferee(s) shall have delivered to the
Company a copy of a letter from the staff of the Securities and Exchange
Commission, or an opinion of counsel, in form and substance reasonably
satisfactory to the Company, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied.  In addition, such certificates shall bear any other legend as may be
required by law.

       (c)   If, following the occurrence of a Purchase Event, Commercial, or
any subsequent transferee(s), seeks to sell or otherwise dispose of the Option
or shares of common stock received or receivable upon exercise thereof and it or
its transferee(s) shall then be required under applicable law or regulation to
have such Option or common stock registered with a government agency before
making such sale or disposition, then, in such event, the Company shall, upon
the written request of Commercial or its transferee(s), file with such agency as
promptly as practicable after receiving such request, an appropriate
registration statement under such law or regulation registering (i) the Option
granted hereby, and (ii) the shares of common stock received or receivable upon
exercise of the Option in accordance with such written request of Commercial, or
its transferee(s). The Company will use its best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective or such shorter time as may be

                                       4
<PAGE>
 
reasonably necessary to effect such sales or other dispositions. Commercial, or
any subsequent transferee, shall have the right to demand two such
registrations; provided, however, that the Company shall be required to bear the
               --------  -------     
expenses related only to the first such registration, and Commercial or any
subsequent transferee shall bear such expenses to the extent related to the
second. The foregoing notwithstanding, if, at the time of any request by
Commercial or any subsequent transferee for registration as provided above, the
Company is in registration with respect to an underwritten public offering of
shares of Company common stock, and if in the good faith judgment of the
managing underwriter or managing underwriters, or, if none, the sole underwriter
or underwriters, of such offering the inclusion of Commercial's or any
subsequent transferee's(s') Option or shares with respect thereto would
interfere with the successful marketing of the shares of Company common stock
offered by the Company, the number of shares otherwise to be covered in the
registration statement contemplated hereby may be reduced; and provided,
                                                               --------
however, that after any such required reduction the number of shares to be
-------            
included in such offering for the account of Commercial or any subsequent
transferee shall constitute at least 25% of the total number of shares to be
issued by Commercial or any subsequent transferee and the Company in the
aggregate; and provided further, however, that if such reduction occurs, then
               -------- ------- 
the Company shall file a registration statement for the balance as promptly as
practical and no reduction shall thereafter occur. Commercial or any subsequent
transferee(s) shall provide all information reasonably requested by the Company
for inclusion in any registration statement to be filed hereunder. If requested
by Commercial, in connection with any such registration, the Company will become
a party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating itself in respect of representations,
warranties, indemnities and other agreements customarily included in such
underwriting agreements.

       5.    REPRESENTATIONS.  The Company hereby represents and warrants to,
and covenants with, Commercial as follows:

             (a)   The Company has taken all necessary corporate action to
       authorize and reserve for issuance the full number of shares of the
       Company's common stock issuable upon exercise of the Option, and shall
       continue to reserve such shares until this Agreement is terminated as
       provided herein. The Company has full corporate power and authority to
       execute and deliver this Agreement and to consummate the transactions
       contemplated hereby. The execution and delivery of this Agreement and the
       consummation of the transactions contemplated hereby have been duly
       authorized by all necessary corporate action on the part of the Company
       and no other corporate proceedings on the part of Company are necessary
       to authorize this Agreement or to consummate the transactions so
       contemplated. This Agreement has been duly and validly executed and
       delivered by the Company. This Agreement is the valid and legally binding
       obligation of the Company;

             (b)   The shares to be issued upon due exercise, in whole or in
       part, of the Option, when paid for as provided herein, will be duly
       authorized, validly issued, fully paid, nonassessable and will be
       delivered free and clear of all claims, liens, encumbrances and security
       interests and not subject to preemptive rights;

                                       5
<PAGE>
 
             (c)   The Company will not, by charter amendment or through
       reorganization, consolidation, merger, dissolution or sale of assets, or
       by any other voluntary act, avoid or seek to avoid the observance or
       performance of any of the covenants, stipulations or conditions to be
       observed or performed hereunder by the Company; and
     
             (d)   The Company will promptly take all action as may from time to
       time be required (including (x) complying with all premerger
       notification, reporting and waiting period requirements specified in 15
       U.S.C. (S)18a and regulations promulgated thereunder and (y) in the
       event, under the Home Owners' Loan Act, as amended ("HOLA"), the Bank
       Holding Company Act of 1956, as amended, or the Change in Bank Control
       Act of 1978, as amended, or any state banking law, prior approval of or
       notice to the OTS, the Federal Reserve Board or to any state regulatory
       authority is necessary before the Option may be exercised, cooperating
       fully with Commercial or any transferee(s) hereof in preparing such
       applications or notices and providing such information to the OTS or the
       Federal Reserve Board or such state regulatory authority as they may
       require) in order to permit Commercial or any transferee(s) hereof to
