  Dear Stockholder:
    
       You are invited to attend a special meeting of stockholders (the 
  "Special Meeting") of Heritage Financial, Ltd. ("Heritage") to be held at the
  main office of Hawkeye Federal Savings Bank, 715 8th Street, Boone, Iowa, on
  Thursday, September 26, 1996 at 6:00p.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 Heritage and its principal subsidiary, Hawkeye Federal Savings
  Bank ("Hawkeye"), by Commercial Federal Corporation ("Commercial") and its
  principal subsidiary, Commercial Federal Bank, a Federal Savings Bank (the
  "Bank"), respectively, in accordance with the Reorganization and Merger
  Agreement dated as of May 16, 1996 by and among Commercial, the Bank, Heritage
  and Hawkeye (the "Merger Agreement").  Pursuant to the Merger Agreement (1)
  Heritage will merge into Commercial and the outstanding shares of Heritage's
  common stock will be converted into cash and shares of Commercial common stock
  as set forth below and in the accompanying Prospectus/Proxy Statement (the
  "Acquisition Merger") and (2) Hawkeye will, following the Acquisition Merger,
  merge into the Bank (collectively, the "Merger").  Pursuant to the Merger
  Agreement, each share of Heritage common stock outstanding at the time of the
  Acquisition Merger (except for (i) shares held by Heritage stockholders who
  have properly perfected dissenters' rights of appraisal ("Dissenting Shares");
  and (ii) shares held by Heritage or any of its subsidiaries (other than shares
  held in any 401(k) plan or in a fiduciary capacity) will be converted into the
  right to receive (a) $18.73 in cash (subject to increase, as discussed below)
  and (b) a number of shares of Commercial common stock (such number of shares
  referred to as the "Exchange Ratio") based upon the "Average NYSE Closing
  Price" of Commercial common stock (i.e., the arithmetic mean of the per share
  closing price of the Commercial common stock as reported on the New York Stock
  Exchange ("NYSE") for the twenty-fifth through the sixth trading day inclusive
  immediately preceding the business day prior to the later of the date on which
  all requisite federal and state regulatory approvals are obtained (including
  the passage of any requisite waiting periods in respect thereof) or the date
  of the Special Meeting) (the "Determination Period") as follows: (i) if the
  Average NYSE Closing Price is equal to or greater than $33.50 but equal to or
  less than $36.00, the Exchange Ratio shall be 2.719 shares of Commercial
  common stock; (ii) if the Average NYSE Closing Price is less than $41.00 but
  greater than $36.00, the Exchange Ratio shall be that number of shares of
  Commercial common stock equal to the quotient that results by dividing 97.88
  by the Average NYSE Closing Price; (iii) if the Average NYSE Closing Price is
  equal to or greater than $41.00 but equal to or less than $45.00, the Exchange
  Ratio shall be 2.387 shares of Commercial common stock; (iv) if the Average
  NYSE Closing Price is greater than $45.00 but less than $47.50, the Exchange
  Ratio shall be that number of shares of Commercial common stock equal to the
  quotient that results by dividing 107.43 by the Average NYSE Closing Price;
  (v) if the Average NYSE Closing Price is equal to or greater than $47.50 but
  less than or equal to $50.00, then the Exchange Ratio shall be 2.262 shares of
  Commercial common stock; and (vi) if the Average NYSE Closing Price is greater
  than $50.00, then the Exchange Ratio shall be equal to the quotient that
  results by dividing 113.08 by the Average NYSE Closing Price.

       The cash consideration to be received by Heritage stockholders in the
  Merger may be increased depending on the extent to which a currently impaired
  asset of Heritage recovers value prior to or for a certain period of time
  following the Merger.  As of June 30, 1996, Heritage had approximately 
  $1.8 million invested in assets secured by equipment leases (the "Bennett 
  Funding Asset") sold by Bennett Funding Group and certain of its affiliates
  ("Bennett").  Pursuant to the Merger Agreement, Heritage has agreed that prior
  to the Merger it will either (i) sell
<PAGE>
 
     
  the Bennett Funding Asset in its entirety or (ii) establish a specific loan
  loss reserve equal to the carrying value of the Bennett Funding Asset on the
  accounting records of Heritage. As of the date of this Prospectus/Proxy
  Statement, the Bennett Funding Asset has not been sold. However, as of June
  30, 1996, Heritage established a specific loan loss reserve of $1.8 million
  for the entire amount of the Bennett Funding Asset. If the Bennett Funding
  Asset is sold prior to the effective time of the Merger, the cash portion of
  the Merger Consideration will be increased by 64% of the recovery recognized
  from such sale which represents the recovered amount less the agreed upon tax
  impact of 36%. Commercial and Heritage have also agreed that, following the
  Merger and until the earlier of September 30, 1999 or the full collection of
  the Bennett Funding Asset, 64% of any cash proceeds (net of certain expenses)
  received from the sale or collection of the Bennett Funding Asset will be
  distributed to those individuals who were stockholders of Heritage immediately
  prior to the Merger, in the manner set forth in the Merger Agreement and a
  related agreement. See "The Merger -- Bennett Funding Asset" in the enclosed
  Prospectus/Proxy Statement for detailed information on the Bennett Funding
  Asset and the manner of its administration following consummation of the
  Merger in the event it is not sold prior thereto.     
    
       Based on the closing price of Commercial common stock on the NYSE on
  August 12, 1996 of $38.25 per share and assuming no value is recovered in
  connection with the Bennett Funding Asset, each share of Heritage common stock
  would be exchanged for $18.73 in cash and 2.559 shares of Commercial common
  stock.  Such Exchange Ratio may increase or decrease depending on the Average
  NYSE 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 subsidiary savings institution. Consum-
  mation of the Merger is conditioned upon, among other things, receipt of
  all required regulatory approvals and approval by Heritage's stockholders.

       At the Special Meeting, stockholders of Heritage will consider and vote
  upon approval of the Acquisition Merger and the Merger Agreement.  In
  addition, the stockholders of Heritage 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.  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 Heritage 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.

       Heritage's Board of Directors has received the opinion of its financial
  advisor, Hovde Financial, Inc., that the consideration to be received by
  Heritage's stockholders (without including any consideration resulting from
  the Bennett Funding Asset) 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]

                      For Special Meeting of Stockholders

                   -----------------------------------------
    
     This Prospectus/Proxy Statement is being furnished to the holders of the

Bank, 715 8th Street, Boone, Iowa, on Thursday, September 26, 1996 at 6:00 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 Heritage 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; Heritage; and Hawkeye Federal Savings Bank ("Hawkeye"), the wholly-

"Merger Agreement"), which sets forth the terms and conditions of the
Acquisition Merger and also provides for the subsequent merger of Hawkeye into
the Bank; (ii) to consider and vote upon adjournment of the Special Meeting if

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 Heritage Common Stock
outstanding at the time of the Acquisition Merger (except for (i) shares held by
Heritage stockholders who have properly perfected dissenters' rights of
appraisal ("Dissenting Shares"); and (ii) shares held by Heritage or any of its
subsidiaries, other than shares held in any 401(k) plan or in a fiduciary
capacity) will be converted into the right to receive (a) $18.73 in cash
(subject to increase, as discussed below) and (b) a number of shares of common
stock, par value $0.01 per share (the "Commercial Common Stock") of Commercial
(such number of shares referred to as the "Exchange Ratio") based upon the
"Average NYSE Closing Price" of Commercial Common Stock (i.e., the arithmetic
mean of the per share closing price of the Commercial Common Stock as reported
on the New York Stock Exchange ("NYSE") for the twenty-fifth through the sixth
trading day immediately preceding the business day prior to the later of the
date on which all requisite federal and state regulatory approvals are obtained
(including the passage of any requisite waiting periods in respect thereof) or
the date of the Special Meeting (the "Determination Period")) as follows:  (i)
if the Average NYSE Closing Price is equal to or greater than $33.50 but equal
to or less than $36.00, the Exchange Ratio shall be 2.719 shares of Commercial
Common Stock; (ii) if the Average NYSE Closing Price is less than $41.00 but
greater than $36.00, the Exchange Ratio shall be that number of shares of
Commercial Common Stock equal to the quotient that results by dividing 97.88 by
the Average NYSE Closing Price; (iii) if the Average NYSE Closing Price is equal
to or greater than $41.00 but equal to or less than $45.00, the Exchange Ratio
shall be 2.387 shares of Commercial Common Stock; (iv) if the Average NYSE
Closing Price is greater than $45.00 but less than $47.50, the Exchange Ratio
shall be that number of shares of Commercial Common Stock equal to the quotient
that results by dividing 107.43 by the Average NYSE Closing Price; (v) if the
Average NYSE Closing Price is equal to or greater than $47.50 but less than or
equal to $50.00, then the Exchange Ratio shall be 2.262 shares of Commercial
Common Stock; and (vi) if the Average NYSE Closing Price is greater than $50.00,
then the Exchange Ratio shall be equal to the quotient that results by dividing
113.08 by the Average NYSE Closing Price (the cash consideration, including any
increase as described below, and shares of Commercial Common Stock to be
received by holders of
<PAGE>
 

the Heritage Common Stock pursuant to the Merger Agreement are collectively
referred to herein, as the context requires, as the "Merger Consideration").
    
     The cash consideration to be received by Heritage stockholders in the
Merger may be increased depending on the extent to which a currently impaired
asset of Heritage recovers value prior to or for a certain period of time
following the Merger. As of June 30, 1996, Heritage had approximately $1.8
million invested in assets secured by equipment leases sold by Bennett Funding
Group and certain of its affiliates (the "Bennett Funding Asset"). Pursuant to
the Merger Agreement, Heritage has agreed that prior to the Merger, it will
either (i) sell the Bennett Funding Asset in its entirety or (ii) establish a
specific loan loss reserve equal to the carrying value of the Bennett Funding
Asset on the accounting records of Heritage. As of the date of this
Prospectus/Proxy Statement, the Bennett Funding Asset has not yet been sold.
However, as of June 30, 1996, Heritage established a specific loan loss reserve
of $1.8 million for the entire amount of the Bennett Funding Asset. If the
Bennett Funding Asset is subsequently sold prior to the effective time of the
Merger, the cash portion of the Merger Consideration will be increased by 64% of
the recovery recognized from such sale which represents the recovered amount
less the agreed upon tax impact of 36%. Commercial and Heritage have also agreed
that, following the Merger and until the earlier of September 30, 1999 or the
full collection of the Bennett Funding Asset, 64% of any cash proceeds (net of
certain expenses) received from the sale or collection of the Bennett Funding
Asset will be distributed to those individuals who were stockholders of Heritage
immediately prior to the Merger in the manner set forth in the Merger Agreement
and a related agreement. For additional information, see "The Merger -- Bennett
Funding Asset."     
    
     Based on the closing price of Commercial Common Stock on the NYSE on August
12, 1996 of $38.25 per share and assuming no value is recovered in connection
with the Bennett Funding Asset, each share of Heritage Common Stock would be
exchanged for $18.73 in cash and 2.559 shares of Commercial Common Stock.  Cash
will be paid in lieu of fractional shares.      

     Commercial has filed a registration statement on Form S-4 (the
"Registration Statement") 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 Commercial Common Stock to be
issued upon consummation of the Acquisition Merger.  See "Available
Information."  This Prospectus/Proxy Statement constitutes a prospectus of
Commercial with respect to the issuance of shares of Commercial Common Stock to
the stockholders of Heritage upon consummation of the Acquisition Merger.

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

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

     THE SHARES OFFERED HEREBY ARE NOT SAVINGS ACCOUNTS OR DEPOSITS AND ARE NOT
INSURED BY THE SAVINGS ASSOCIATION INSURANCE FUND, THE FEDERAL DEPOSIT INSURANCE
CORPORATION OR ANY OTHER GOVERNMENT AGENCY.
    
     This Prospectus/Proxy Statement and the accompanying proxy card are first
being sent to the stockholders of Heritage on or about August 21, 1996.      

     This Prospectus/Proxy Statement does not cover any resales of the
Commercial Common Stock offered hereby to be received by the stockholders deemed
to be affiliates of Commercial or Heritage upon consummation of the Merger.  No
person is authorized to make use of this Prospectus/Proxy Statement in
connection with such resales, although such securities may be traded without the
use of this Prospectus/Proxy Statement by those stockholders of Heritage not
deemed to be affiliates of Commercial or Heritage.
    
        The date of this Prospectus/Proxy Statement is August 21, 1996.

  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 largest depository institution
  headquartered in Nebraska.  At March 31, 1996, Commercial had assets of $6.6
  billion and stockholders' equity of $400.4 million.  Based upon total assets
  at that date, Commercial was the 18th largest publicly held thrift holding
  company in the United States.  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.  At March 31, 1996, the Bank operated 38 branch offices in
  Nebraska, 20 branch offices in greater metropolitan Denver, Colorado, 18
  branch offices in Oklahoma, 24 branch offices in Kansas and one branch office
  in Iowa.  Subsequent to March 31, 1996, the Bank consolidated four branches in
  Nebraska due to market overlap resulting from the acquisition of Conservative
  Savings Corporation ("Conservative") and opened an additional branch in
  Oklahoma.  Accordingly, at June 30, 1996, the Bank operated a 98 branch
  network.  Throughout its 109 year history, the Bank has emphasized customer
  service.  To serve its customers, the Bank conducts loan origination
  activities through its branch office network, loan offices of its wholly-owned
  mortgage banking subsidiary and a nationwide correspondent network consisting
  of approximately 400 mortgage loan originators.  The Bank also provides
  insurance and securities brokerage and other retail financial services.

       On October 2, 1995, Commercial completed the acquisition of Railroad
  Financial Corporation ("Railroad"), headquartered in Wichita, Kansas, the
  holding company for Railroad Savings Bank, FSB.  Railroad operated 18 full-
  service branch offices and 71 agency offices throughout the State of Kansas
  and, at acquisition date, had $602.9 million in total assets, $421.4 million
  in deposits and $27.7 million in stockholders' equity.  On February 1, 1996,
  Commercial completed the acquisition of Conservative, headquartered in Omaha,
  Nebraska, the holding company for Conservative Savings Bank, FSB.
  Conservative operated seven offices in Nebraska, one office in Iowa and one

                                       3
<PAGE>
 
  office in Kansas, and at February 1, 1996 had $302.9 million in total assets,
  $197.9 million in deposits and $35.1 million in stockholders' equity.

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

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

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

       For additional information, see "Commercial Federal Corporation and
  Commercial Federal Bank, a Federal Savings Bank" herein.

  Heritage Financial, Ltd. and Hawkeye Federal Savings Bank

       Heritage is a savings and loan holding company for Hawkeye. Heritage
  became the holding company for Hawkeye effective February 23, 1990.  In 1992,
  Heritage acquired First Federal Savings Bank ("First Federal") of Carroll,
  Iowa in a voluntary supervisory conversion.  First Federal was merged with
  Hawkeye in March 1995.  Hawkeye's primary business is the solicitation of
  savings deposits from the general public and the origination of loans secured
  by residential real estate through its main office and six branch offices.
  Hawkeye participates in the secondary mortgage market through the purchase of
  mortgage-backed securities and through correspondent relationships which
  involve the origination of residential real estate loans.  It also invests
  funds in securities approved for investment by federal regulations, including
  obligations of the United States and its agencies.  Hawkeye has expanded its
  operations to include consumer and commercial lending, demand and commercial
  checking, and money market deposit accounts.  Hawkeye's income is derived
  largely from interest and fees in connection with lending activities.  Its
  principal expenses are interest paid on savings deposits and operating
  expenses.  At March 31, 1996, Heritage had total consolidated assets of $185.4
  million, total deposits of $160.1 million and total stockholders' equity of
  $14.0 million.

       Heritage's principal executive offices are located at 715 8th Street,
  Boone, Iowa  50036, and its telephone number at that address is (515) 432-
  1220.

       For additional information, see "Heritage Financial, Ltd.," "Business of
  Heritage Financial, Ltd." and the Consolidated Financial Statements of
  Heritage included elsewhere herein.

  The Merger

       General.  The Merger Agreement provides for the acquisition of Heritage
  by Commercial, and the subsequent merger of Hawkeye into the Bank, as follows:
  (i) Heritage will merge into Commercial, with Commercial as the surviving
  corporation, pursuant to which the outstanding shares of Heritage Common Stock
  (except for (a) Dissenting Shares and (b) shares of Heritage Common Stock held
  by Heritage or any of its

                                       4
<PAGE>
 
  subsidiaries (other than shares held in any 401(k) plan or in a fiduciary
  capacity)) will be converted into cash and shares of Commercial Common Stock
  as set forth below under " -- Conversion of Heritage Common Stock" (the
  "Acquisition Merger"); and (ii) Hawkeye will, following the Acquisition
  Merger, merge into the Bank, with the Bank as the surviving savings
  institution (the "Bank Merger") (collectively, the "Merger").  Upon
  consummation of the Acquisition Merger (the "Acquisition Merger Effective
  Time"), Heritage will have merged into Commercial.  Upon consummation of the
  Bank Merger (the "Bank Merger Effective Time"), Hawkeye 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.

       At a meeting held on May 16, 1996, the Board of Directors of Heritage
  (the "Heritage Board") unanimously adopted the Merger Agreement and approved
  the transactions contemplated thereby.  The Heritage Board considered the
  Merger and the terms of the Merger Agreement, including the Merger
  Consideration, in light of economic, financial, legal, market and other
  factors and concluded that the Merger is in the best interests of Heritage and
  its stockholders.

       The Heritage Board believes that the Merger is in the best interests of
  Heritage and its stockholders and recommends that Heritage'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 Recommendation of the Heritage
  Board of Directors" herein and the Merger Agreement attached as Annex A
  hereto.
    
       Financial Advisor and Opinion of Financial Advisor.  The Board of
  Directors of Heritage has received the written opinion of its financial
  advisor Hovde Financial, Inc. ("Hovde") that, as of the date of such opinion,
  based upon and subject to the assumptions, factors and limitations set forth
  therein, the consideration to be received by holders of Heritage Common Stock
  in the Acquisition Merger (without including any consideration which may
  result from the sale or recovery of the Bennett Funding Asset) is fair from a
  financial point of view.  A copy of the Hovde opinion dated August 21, 1996
  is attached as Annex B hereto, and the description set forth herein is
  qualified in its entirety by reference to this opinion.      

       Conversion of Heritage Common Stock.  Pursuant to the Merger Agreement,
  each share of Heritage Common Stock outstanding at the Acquisition Merger
  Effective Time (other than Dissenting Shares and shares of Heritage Common
  Stock held by Heritage or any of its subsidiaries (other than shares held in
  any 401(k) plan or in a fiduciary capacity) will be converted into the right
  to receive (a) $18.73 in cash (subject to increase in the event of the sale or
  recovery of the Bennett Funding Asset) and (b) a number of shares of
  Commercial Common Stock (such number of shares referred to as the "Exchange
  Ratio") based upon the Average NYSE Closing Price of Commercial Common Stock
  (i.e., the arithmetic mean of the per share closing price of the Commercial
  Common Stock as reported on the NYSE for the twenty-fifth through the sixth
  trading day immediately preceding the business day prior to the later of the
  date on which all requisite federal and state regulatory approvals are
  obtained (including the passage of any requisite waiting periods in respect
  thereof) or the date of the Special Meeting) as follows:  (i) if the Average
  NYSE Closing Price is equal to or greater than $33.50 but equal to or less
  than $36.00, the Exchange Ratio shall be 2.719 shares of Commercial Common
  Stock; (ii) if the Average NYSE Closing Price is less than $41.00 but greater
  than $36.00, the Exchange Ratio shall be that number of shares of Commercial
  Common Stock equal to the quotient that results by dividing 97.88 by the
  Average NYSE Closing Price; (iii) if the Average NYSE Closing Price is equal
  to or greater than $41.00 but equal to or less than $45.00, the Exchange Ratio
  shall be 2.387 shares of Commercial Common Stock; (iv) if the Average NYSE
  Closing Price is greater than $45.00 but less than $47.50, the Exchange Ratio
  shall be that number of shares of Commercial Common Stock equal to the
  quotient that results by dividing 107.43 by the Average NYSE Closing Price and
  (v) if the Average NYSE Closing Price is equal to or greater than $47.50 but
  less than or equal to $50.00, then the Exchange Ratio shall be 2.262 shares of
  Commercial Common Stock; and (vi) if the Average NYSE Closing Price is greater
  than $50.00, then the Exchange Ratio shall be equal to the quotient that
  results by dividing 113.08 by the Average NYSE Closing Price.

                                       5
<PAGE>
 
     
       The cash consideration to be received by Heritage stockholders in the
  Merger may be increased depending on the extent to which Heritage recovers
  value on the Bennett Funding Asset prior to or following the Merger. As of May
  16, 1996, Heritage had approximately $1.8 million invested in the Bennett
  Funding Asset. Pursuant to the Merger Agreement, Heritage has agreed that
  prior to the Merger, it will either (i) sell the Bennett Funding Asset in its
  entirety, or (ii) establish a specific loan loss reserve equal to the carrying
  value of the Bennett Funding Asset on the accounting records of Heritage. As
  of the date of this Prospectus/Proxy Statement, the Bennett Funding Asset has
  not yet been sold. However, as of June 30, 1996, Heritage established a
  specific loan loss reserve of $1.8 million for the entire amount of the
  Bennett Funding Asset. If the Bennett Funding Asset is subsequently sold prior
  to the effective time of the Merger, the cash portion of the Merger
  Consideration will be increased by 64% of the recovery recognized from such
  sale which represents the recovered amount less the agreed upon tax impact of
  36%. Commercial and Heritage have agreed that, following the Merger and until
  the earlier to occur of September 30, 1999 or the full collection of the
  Bennett Funding Asset, 64% of any cash proceeds received (net of expenses)
  from the sale or collection of the Bennett Funding Asset will be distributed
  to those individuals who were stockholders of Heritage immediately prior to
  the Merger. For additional information see "The Merger--Bennett Funding
  Asset."     
       Treatment of Heritage Stock Options.  Immediately prior to the
  Acquisition Merger Effective Time, each holder of an option outstanding under
  the Heritage Financial, Ltd. 1994 Stock Option Plan (the "Heritage Option
  Plan"), whether or not the option is then exercisable, shall receive in
  cancellation of such option, for each share of Heritage Common Stock subject
  to such option, a cash payment in an amount equal to the Merger Consideration
  less the exercise price of such option, net of any cash which must be withheld
  under federal and state income tax requirements.  For additional information,
  see "The Merger -- Treatment of Heritage Stock Options" and "-- Interests of
  Certain Persons in the Merger" herein.

       Dissenters' Appraisal Rights.  Under the provisions of Iowa law,
  stockholders of Heritage who object to the Acquisition Merger will have a
  statutory right to demand payment of the "fair value" of their Heritage Common
  Stock in cash.  To perfect this right, a Heritage stockholder must (i) not
  vote his or her shares in favor of the Merger Agreement and the Acquisition
  Merger at the Special Meeting and (ii) must take such action as is required by
  the provisions of Part B of Division XIII of the Iowa Business Corporation Act
  ("IBCA"), including delivering written notice of objection to Heritage prior
  to the vote on the Merger Agreement and the Acquisition Merger at the Special
  Meeting.  See "The Merger -- Dissenters' Rights of Appraisal" and Annex C
  hereto.
    
       Voting Agreements.  Concurrent with the execution of the Merger
  Agreement, the directors and executive officers of Heritage entered into
  agreements with Commercial (the "Voting Agreements") to vote their shares of
  Heritage Common Stock in favor of the Merger Agreement and the Acquisition
  Merger.  Such Voting Agreements cover the shares of Heritage Common Stock
  beneficially owned by the directors and executive officers of Heritage as of
  May 16, 1996 as well as any shares subsequently acquired.  A total of 56,064
  shares of Heritage Common Stock (a total of 31% of the shares outstanding as
  of the Record Date) are covered by the Voting Agreements.  See "The Merger --
  Voting Agreements."      

       Conditions to the Merger.  The obligations of Commercial and Heritage to
  effect the Merger are jointly subject to a number of conditions including,
  among other things, the receipt of Heritage 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 including, among
  other things, (i) receipt of a customary legal opinion from Heritage's legal
  counsel; (ii) receipt by Heritage and Hawkeye of certain third party consents
  and approvals; (iii) receipt of a letter from Heritage's independent public
  accountants regarding certain financial information included in this
  Prospectus/Proxy Statement and other matters; (iv) the accuracy of Heritage's
  and Hawkeye's representations and their performance of obligations and
  compliance with covenants and conditions under the Merger Agreement; (v) 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; (vi) the absence of a
  material adverse change (as defined in the Merger Agreement) in the financial
  condition, business and results of operations of Heritage and its

                                       6
<PAGE>
 
  subsidiaries taken as a whole; (vii) the holders of no more than 10% of
  Heritage Common Stock having perfected dissenters' rights of appraisal; and
  (viii) Heritage having charged off or sold the Bennett Funding Asset or
  established a specific loan loss therefor.  The obligations of Heritage and
  Hawkeye 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
  deposit by Commercial of the Merger Consideration with the Exchange Agent;
  (iv) the holders of no more than 10% of Heritage Common Stock having perfected
  dissenters' rights of appraisal; (v) the approval by the NYSE for listing of
  the shares of Commercial Common Stock to be issued in the Acquisition Merger;
  and (vi) 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 Office of Thrift Supervision (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 Heritage stockholders, in a number of circumstances, including:
  (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 January 31,
  1997; (iii) 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; (iv) by Heritage at any time during the two business days
  commencing on the business day immediately following the end of the
  Determination Period if the Average NYSE Closing Price of Commercial Common
  Stock is less than $33.50; provided, however, that Heritage shall not be
  entitled to terminate the Merger Agreement on this basis if Commercial
  exercises its option to adjust the Merger Consideration so that it equals cash
  in the amount of $18.73 (subject to increase in the event of the sale or
  recovery of the Bennett Funding Asset) and that number of shares of Commercial
  Common Stock arrived at by dividing 91.08 by the Average NYSE Closing Price of
  Commercial Common Stock; or (v) by Heritage, in the event the fiduciary duties
  of the Heritage Board of Directors require such termination in connection with
  entering into an agreement with a third party.  In the event the Merger
  Agreement is terminated by Heritage and, prior to such termination, a
  "Termination Event" (as such term is defined herein) has occurred (except if
  such termination is due to the noncompliance of Commercial or the Bank with
  their conditions under the Merger Agreement), Heritage will be obligated to
  pay a termination fee in the amount of $1.0 million.  For additional
  information, see "The Merger -- Amendment or Termination of the Merger
  Agreement" and " -- Termination Fee".

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

       Interests of Certain Persons in the Merger.  Shares of Heritage Common
  Stock held by directors, officers and employees of Heritage will be converted
  into cash and Commercial Common Stock under the Merger Agreement on the same
  basis as shares held by other Heritage stockholders.  Directors, officers and
  employees of Heritage who

                                       7
<PAGE>
 
  hold unexercised options to purchase Heritage Common Stock under the Heritage
  Option Plan at the Acquisition Merger Effective Time will have their stock
  options converted into cash under the terms of the Merger Agreement.  At the
  Record Date, officers, directors and the estate of a former director of
  Heritage held options to purchase 23,037 shares of Heritage Common Stock at an
  exercise price of $56.00 per share.

       It is also currently anticipated that, as a result of the Merger, three
  executive officers and four other officers of Heritage will become entitled to
  severance payments and benefits under their current employment or severance
  agreements with Heritage and Hawkeye.  The severance payments due such
  officers in connection with their termination of employment following the
  Merger have an approximate aggregate value of $892,000.

       Commercial has also agreed to indemnify the employees, agents, directors
  and officers of Heritage and its subsidiary to the same extent they are
  indemnified under Heritage's Articles of Incorporation or Bylaws in effect at
  the date of the Merger Agreement or arising by operation of law.  In addition,
  with respect to persons serving as officers or directors of Heritage and
  Hawkeye immediately prior to the Acquisition Merger Effective Time, Commercial
  has further agreed to purchase individual directors' and officers' liability
  coverage with respect to acts or omissions occurring prior to the Acquisition
  Merger Effective Time at an individual cost of not more than $3,500 per person
  and an aggregate cost of $55,000.

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

       Federal Income Tax Consequences.  Commercial and Heritage will rely upon
  an opinion of Deloitte & Touche LLP, tax advisor to Commercial, to the effect
  that, among other things, (i) the Acquisition Merger should be treated for
  federal income tax purposes as a tax-free reorganization under Section 368(a)
  of the Internal Revenue Code of 1986, as amended (the "Code"); (ii) the gain,
  if any, to be realized by a Heritage stockholder who receives Commercial
  Common Stock and cash in exchange for Heritage Common Stock should be
  recognized, but not in excess of the amount of cash received; (iii) if the
  exchange has the effect of the distribution of a dividend (which determination
  is made on a stockholder-by-stockholder basis), then the amount of gain
  recognized that is not in excess of each stockholder's ratable share of
  undistributed earnings and profits should be treated as a dividend; and (iv)
  cash received by Heritage stockholders in lieu of fractional share interests
  in Commercial Common Stock should 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 should qualify as capital gain or loss if the stockholders held the
  Heritage 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 will be accounted for under the
  purchase method of accounting in accordance with generally accepted accounting
  principles, resulting in adjustments to Heritage's assets and liabilities to
  reflect their fair values at the date of the Acquisition Merger.

  Comparison of Stockholder Rights

       Upon consummation of the Merger, holders of Heritage Common Stock, whose
  rights are presently governed by Iowa law and Heritage's Articles of
  Incorporation and Bylaws, and indirectly Hawkeye's Charter and Bylaws, will
  become stockholders of Commercial, a Nebraska corporation.  Accordingly, their
  rights will be governed by Nebraska law and by the Articles of Incorporation
  and Bylaws of Commercial, and indirectly by the Bank's Charter and Bylaws.
  Certain differences arise from the differences between Iowa and Nebraska
  corporate law, between the Articles of Incorporation and Bylaws of Heritage
  and the Articles of Incorporation and Bylaws of Commercial and between the
  Charter and Bylaws of Hawkeye and the Bank, including, among other things, the
  number of authorized shares of capital stock, the calling of special meetings
  of stockholders, cumulative voting in the election of directors, the number
  and term of directors, advance notice requirements for nominations of
  directors and presentation of new business at annual or special meetings of
  stockholders, limitations on acquisitions of capital stock, approval

                                       8
<PAGE>
 
  requirements for mergers, consolidations, sales of substantially all assets
  and dissolutions, limitations on directors' liability and amendment of
  corporate governing documents.  In addition, Commercial has in effect a
  shareholder rights plans.  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 Heritage 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
  of Heritage Common Stock represented and voting at the Special Meeting is
  required in order to approve any such adjournment.  Heritage'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.

                 SUMMARY CONSOLIDATED FINANCIAL INFORMATION OF
                         COMMERCIAL FEDERAL CORPORATION

       The following summary consolidated financial data of Commercial as of and
  for the years ended June 30, 1995, 1994, 1993, 1992 and 1991 has been derived
  from and should be read in conjunction with Commercial's consolidated
  financial statements and the notes thereto, as restated to include the
  accounts and results of operation of Railroad.  The following summary
  consolidated interim financial data for the nine months ended March 31, 1996
  and 1995 has been derived from unaudited consolidated interim financial
  statements which, in the opinion of management, include all adjustments
  (consisting of normal recurring adjustments except for the restatement of all
  prior periods as a result of the pooling of Railroad and the accelerated
  amortization of goodwill recorded during the nine months ended March 31,
  1995), considered necessary for a fair presentation.  The summary consolidated
  financial data should be read in conjunction with Commercial's audited
  Consolidated Financial Statements and related Notes, which have been restated
  to include the accounts and results of operations of Railroad, as reflected on
  the Company's Current Report on Form 8-K dated March 19, 1996, which is
  incorporated herein by reference.  The consolidated financial data for the
  nine months ended March 31, 1996 is not necessarily indicative of the

                  INFORMATION CONCERNING THE SPECIAL MEETING

  General
      
       This Prospectus/Proxy Statement is being furnished as part of the
  solicitation of proxies by the Board of Directors of Heritage from holders of
  the outstanding shares of Heritage Common Stock as of the Record Date for use
  at the Special Meeting to be held on September 26, 1996, and any adjournments
  thereof.  This Prospectus/Proxy Statement, and the accompanying proxy card,
  are first being mailed to stockholders of Heritage on or about August 21,
  1996.     

       The principal purpose of the Special Meeting is to consider and vote upon
  the approval of the Acquisition Merger, pursuant to which Heritage will merge
  into Commercial, and the Merger Agreement among Commercial, the Bank, Heritage
  and Hawkeye, which sets forth the terms and conditions of the Acquisition
  Merger and also provides for the Bank Merger.  See "The Merger -- Conversion
  of Heritage 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 Heritage 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 "Heritage"
  refer to the parent corporation only or to both the parent corporation and its
  subsidiaries, depending on the context.

  Recent Events

    
       Repurchase of Stock. On August 21, 1996, Commercial consummated the 
  repurchase of 1,250,100 shares (8.3% of the outstanding shares of Commercial
  Common Stock prior to the repurchase) of Commercial Common Stock from CAI
  Corporation ("CAI"), a Dallas-based investment company, for an aggregate
  purchase price of $48.9 million, consisting of cash of $28.2 million and a
  warrant (valued at $20.7 million) which would have enabled Commercial to
  purchase stock in CAI. Commercial has also agreed to reimburse certain
  expenses of CAI. After repurchase of such shares, a total of 13,844,036 shares
  of Commercial Common Stock were issued and outstanding. The cash portion of
  the repurchase was financed by a loan from a financial institution. Such loan
  is secured by a portion of the outstanding shares of the common stock of the
  Bank. Concurrent with the close of the repurchase, two directors of
  Commercial, Robin R. Glackin and Steven M. Ellis, who also serve as executive
  officers of CAI, resigned from the Board of Directors.     

       Deposit Insurance Premiums.  The Bank's and Hawkeye's 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 became effective September
  30, 1995.  Subsequently, the FDIC reduced the premium rate for the most highly
  rated BIF-insured institutions to the statutory minimum of $1,000 per 
  semi-annual period.  The FDIC amendment creates a substantial disparity in the
  deposit insurance premiums paid by BIF and SAIF members and places 
  SAIF-insured savings institutions at a significant competitive disadvantage 
  to BIF-insured institutions.

       A number of proposals have been considered to recapitalize the SAIF in
  order to eliminate the premium disparity.  The U.S. Senate and the U.S. House
  of Representatives have both, as part of a budget reconciliation package to
  balance the federal budget, approved legislation requiring a one time
  assessment of an amount sufficient to bring the SAIF to a level equal to 1.25%
  of insured deposits (estimated to be approximately 0.85% of insured deposits)
  to be imposed on all SAIF-insured deposits held as of March 31, 1995.  This
  assessment was originally scheduled to be payable during the first quarter of
  1996.  However, on April 25, 1996, this measure was dropped in order to pass
  the 1996 budget reconciliation bill.  It is anticipated that this measure may
  be offered again this year but details are unclear.  Assuming a 0.85%
  assessment on a $4.2 billion deposit base, the assessment would result, on a
  pro forma basis as of March 31, 1996, in a one-time after-tax charge of
  approximately $22.9 million to Commercial.  Such assessment would have the
  effect of reducing the Bank's tangible capital to $371.7 million, or

                                       15
<PAGE>
 
  5.64% of adjusted total assets (historical - $394.6 million, or 5.97%), core
  capital to $389.2 million, or 5.89% of adjusted total assets (historical -
  $412.1 million or 6.21%), and risk-based capital to $425.1 million, or 12.70%
  of risk-weighted assets (historical - $448.0 million or 13.39%).  The Bank
  would, on a pro forma basis as of March 31, 1996, continue to exceed the
  minimum requirements to be classified as a "well capitalized" institution
  under applicable regulations.  If such a special assessment were required and
  the SAIF as a result was fully recapitalized, it could have the effect of
  reducing the Bank's deposit insurance premiums to the SAIF, thereby increasing
  net income in future periods.
    
       Also under consideration by Congress are proposals relating to merger of
  the BIF and SAIF funds and the elimination of the thrift charter. Management
  of Commercial is unable to predict accurately at this time whether any of
  these proposals will be adopted in their current form or the impact of these
  proposals on Commercial.      

        

       Payment of Accrued Tax Liabilities.  As a result of the final disposition
  of a subsidiary's interest in a nuclear generating facility in Palo Verde,
  Arizona in February 1996, Commercial will pay accrued federal and state tax
  liabilities which were previously deferred for financial reporting purposes
  totalling approximately $51.8 million.  These tax payments were paid in June
  1996 for the federal tax liability and will be paid in September and October
  1996 for the state tax liability.  While these payments affect Commercial's
  cash flow position, they are not expected to have a material adverse impact on
  its financial condition and results of operations.

       Bennett Funding Asset.  At June 30, 1996, Heritage had approximately $1.8
  million in loans outstanding to Bennett and certain of its affiliates secured
  by equipment leases.  Management of Heritage understands that approximately
  10,000 individual investors and 200 financial institutions nationwide had
  similar investments or lending relationships with Bennett.  Bennett filed for
  Chapter 11 bankruptcy protection on March 29, 1996, after the principals of
  the company were charged with various criminal offenses relating to the
  leasing transactions.  Upon the filing of the Bennett bankruptcy case, the
  Bennett Funding Asset became nonperforming.

       Heritage management has retained legal counsel to assist Heritage in the
  bankruptcy proceedings and collection efforts.  The reports from the
  bankruptcy trustee and legal counsel allege that significant fraudulent
  activity took place at Bennett.  Based on this and other pertinent
  information, at June 30, 1996, Heritage management decided to fully reserve
  the entire Bennett Funding Asset which had the effect of reducing June 30,
  1996 fourth quarter earnings by $1.8 million less the tax benefit of $600,000
  for a net effect of $1.2 million.  See "The Merger -- Bennett Funding Asset."

  Solicitation, Voting and Revocability of Proxies
      
       The Board of Directors of Heritage has fixed the close of business on the
  Record Date for the determination of the Heritage stockholders entitled to
  notice of and to vote at the Special Meeting.  Accordingly, only holders of
  record of shares of Heritage Common Stock at the close of business on the
  Record 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 228 holders of
  record of the 180,762 shares of Heritage Common Stock then outstanding.  The
  presence, in person or by proxy, of a majority of the total number of
  outstanding shares of Heritage 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 Heritage
  Common Stock is required to approve the Acquisition Merger and the Merger
  Agreement.  The affirmative vote of a majority of the shares of Heritage
  Common Stock represented and voting at        

                                       16
<PAGE>
 
       
  the Special Meeting is required to approve an adjournment of the Special
  Meeting.  It is expected that substantially all of the 56,064 shares of
  outstanding Heritage Common Stock (excluding shares subject to stock options)
  beneficially owned by directors and executive officers of Heritage and their
  affiliates as of the Record Date will be voted FOR approval of the Acquisition
  Merger and the Merger Agreement.  See also "The Merger -- Voting Agreements."
       
       If the accompanying proxy card is properly executed and returned to
  Heritage 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 Heritage 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 Heritage proxy will vote the shares
  represented by such proxy on such matters as determined by a majority of
  Heritage'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 Heritage at its headquarters address or by
  attending the Special Meeting and voting in person.

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



                                   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
  Merger 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 Heritage by
  Commercial, and the subsequent merger of Hawkeye into the Bank, as follows:
  (i) Heritage will merge into Commercial, with Commercial as the surviving
  corporation, pursuant to which the outstanding shares of Heritage Common Stock
  would be converted into cash and shares of Commercial Common Stock as set
  forth below (the Acquisition Merger); and (ii) Hawkeye will then merge into
  the Bank, with the Bank as the surviving savings institution (the Bank Merger)
  (collectively, the Merger).  At the Acquisition Merger Effective Time,
  Heritage will have merged into Commercial.  At the Bank Merger Effective Time,
  Hawkeye 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

                                       17
<PAGE>
 
  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 Heritage are being asked to approve the Merger Agreement
  and the Acquisition Merger.  The affirmative vote of at least a majority of
  the outstanding shares of Heritage Common Stock is required for Heritage's
  stockholders to approve the Merger Agreement and the Acquisition Merger.

  Background of the Merger

       Hawkeye converted from a federal mutual savings and loan association to a
  federal stock savings bank in 1984 and was later acquired by Heritage in 1990
  as part of a holding company reorganization.  In 1992, Hawkeye acquired First
  Federal in a voluntary supervisory conversion.  First Federal was merged with
  Hawkeye in March 1995.

       Hawkeye's primary business has been the solicitation of deposits from the
  public and the origination of one- to four- family mortgage loans.  However,
  over the period 1984-1996, Hawkeye has expanded its operations to include
  consumer and commercial lending, placed a greater emphasis on the development
  of retail banking products and initiated measures, such as the acquisition of
  First Federal, to expand market share in several Iowa communities.  Heritage
  has also pursued the objective of controlling operating expenses as a means of
  improving overall profitability.

       Throughout the period following the conversion, Heritage considered its
  strategic alternatives, taking into account its market area and size, in light
  of the increased rate of consolidation in the financial services industry.  In
  addition, consistent with the overall objective of enhancing the long-term
  value of stockholders' interests, management and the Board of Directors of
  Heritage considered unsolicited business combination proposals from various
  parties, including stockholders.

       Enhancing shareholder value has always been a priority for the Heritage
  Board.  From time to time, Heritage has received expressions of interest from
  parties, usually another financial institution, seeking to acquire Heritage.
  Because a properly structured sale of Heritage could generally have the effect
  of maximizing shareholder value, such expressions of interest have been
  carefully evaluated by the Board. The Board has also periodically consulted
  with financial advisors regarding the value of Heritage and to obtain an
  overview of the market for community financial institutions.

       During 1993 and 1994, Heritage received acquisition proposals from three
  parties, including two Midwest-based community financial institutions.  The
  Board responded to these proposals and authorized the potential acquirors to
  initiate a due diligence review of Heritage and Hawkeye.  However, discussions
  with these parties either failed to lead to a firm and serious proposal or
  contemplated an inadequate level of consideration.

       At a regular board meeting in August 1995, the Board discussed the
  effects of the rapid consolidation that had been occurring among the providers
  of banking and financial services in Hawkeye's market.  The Board considered
  the fact that the larger financial institutions that emerge from such
  consolidations may acquire substantial competitive advantages, including
  greater diversity in their loan portfolios, cost savings through the
  integration of redundant operations and support functions, improved access to
  capital and funding and the ability to spread the costs of developing new
  products and services over a wider customer base.  The Board also reviewed
  other developments, such as the uncertainty surrounding the thrift industry
  due to the deposit insurance premium differential between institutions insured
  by the SAIF and those insured by the BIF, the anticipated effects on the
  thrift industry of regulatory agency consolidation and the attractiveness of
  thrift acquisition premiums.

       The Board concluded that, in light of current market conditions for
  thrift acquisitions, management should develop strategic options to enhance
  shareholder value, including the possible sale of Heritage.  Further, the
  Board authorized the engagement of Hovde to assist in the development of
  strategic options and to assist the Board in

                                       18
<PAGE>
 
  determining whether a business combination would result in a return of value
  to Heritage stockholders that could not be achieved through Heritage's
  continued operation as an independent entity with continued emphasis on
  building shareholder value through expansion of operations, increasing
  earnings and enhancing operating efficiencies.  Finally, the Board established
  an informal threshold of $22 million in total consideration for evaluation of
  the aggregate value of any proposal to acquire Heritage.

       In October 1995, Heritage entered into an agreement relating to financial
  advisory services with Hovde.  During December 1995 and January 1996, Hovde
  contacted a number of financial institutions to determine whether they might
  be interested in a business combination with Heritage.  Hovde also advised the
  Board of Directors throughout this period regarding the relative merits of
  remaining an independent entity.

       In early February 1996, Hovde reported to the Board that expressions of
  interest had been received from six potential acquirors, four of whom had
  submitted specific proposals in excess of the Board's threshold level and each
  of whom had commenced or completed a preliminary due diligence review of
  Heritage.  The potential acquirors, which included Commercial, ranged from
  community financial institutions similar in business and geographic profile to
  Heritage to a large commercial bank headquartered in the Midwest.  The
  proposals contemplated various forms of consideration ranging from (i) all
  cash, (ii) a combination of cash and/or common or preferred stock, or (iii)
  all common stock, or (iv) all preferred stock.

       After extensive review and discussion of the relative merits of each of
  the proposals obtained through Hovde, the Board concluded that the Commercial
  proposal, which at that point in time contemplated convertible preferred stock
  as consideration, was the most attractive based on the level and form of
  consideration offered by Commercial and the anticipated return to Heritage
  stockholders.  The Board authorized management to enter into discussions with
  Commercial in order to refine certain issues relating to its proposal.  The
  initial discussions with Commercial in mid-February 1996 focused on the
  acquisition of Heritage in a merger in which each outstanding share of
  Heritage Common Stock would be converted into shares of a new issue of
  Commercial convertible preferred stock valued at $125 per share or an
  aggregate purchase price of $24.2 million.  However, those negotiations were
  discontinued after a brief period when concerns arose about the illiquidity
  and certain other features of the preferred stock, concerns which the Board
  believed could not be satisfactorily resolved with Commercial prior to the
  execution of a definitive agreement.

       Following the termination of discussions with Commercial, the Board
  concluded that it would be in the best interest of Heritage stockholders to
  continue the ongoing process of evaluation of the three remaining acquisition
  proposals obtained through Hovde.  Based on further analysis of the these
  proposals, the Board eliminated two potential acquirors based on concerns
  about the illiquidity of the consideration being offered, the financial
  strength of the acquirors and the acquirors' ability to consummate the
  transaction in a timely manner.  Consequently, the Board directed management
  to enter into discussions with the remaining possible acquiror, the large
  Midwestern commercial bank.  Over a three-week period, management of Heritage,
  with the assistance of special legal counsel, Breyer & Aguggia, and its
  financial advisor, Hovde, attempted to negotiate the key terms of a definitive
  agreement with this potential acquiror.  However, the negotiations were
  terminated in early March 1996 after a substantial disagreement emerged among
  the parties regarding the level of consideration as well as certain other
  terms of the proposed definitive agreement.

       After the termination of these discussions, the Board met on March 20,
  1996 to review Heritage's strategic options, including consideration of
  Hawkeye's continued operation on a stand-alone basis and the prospects for
  continuing to pursue a business combination.  The Board determined that,
  notwithstanding the fact that earlier discussions with Commercial has reached
  an impasse, significant shareholder value could be realized through a business
  combination with Commercial at the level of aggregate consideration previously
  discussed if the parties could resolve the Board's earlier concerns regarding
  the terms of the Commercial preferred stock.  Accordingly, the Board
  authorized management to resume discussions with Commercial to determine if
  agreement could be reached on the earlier points of disagreement among the
  parties.

       Discussions with Commercial resumed following the Board's March 20, 1996
  meeting.  Management of Heritage reported to the Board on March 27, 1996 that
  significant progress had been made regarding the structure of the preferred
  stock issue proposed by Commercial.  However, management further indicated
  that, as the discussions developed, new concerns had arisen regarding the
  possible impact of proposed federal income tax law changes on the tax-free
  status of the transaction if the form of consideration received by Heritage
  stockholders was Commercial preferred stock.  Under certain congressional and
  Clinton Administration proposals then pending, which included a retroactive
  effective date, the receipt of preferred stock by the stockholders of a
  corporation that was a party to an otherwise tax-free reorganization would
  result in immediate recognition of taxable gain for the recipients if, under
  the proposed rules, the preferred stock was deemed to be functionally
  equivalent to a debt, rather than an equity, security.  Although the parties
  believed that it might be possible to structure a transaction that would not
  be adversely affected by the enactment of this proposed legislation, as a
  consequence of the uncertainty regarding the effects of these proposals on the
  proposed transaction, as well as some continuing concern among Board members
  regarding the lack of liquidity in the proposed preferred stock, the Heritage
  Board concluded that it would be advisable to discuss with Commercial the
  possibility of an exchange of Heritage Common Stock for Commercial Common
  Stock.

       Following additional discussions, the parties reached a tentative
  agreement on an exchange of Heritage Common Stock for consideration of $122.35
  per share with 80% of this amount payable in Commercial Common Stock and the
  balance in cash.  The aggregate value of the proposed exchange was $23.6
  million.  However, immediately thereafter, as the parties proceeded to
  negotiate other terms of the definitive agreement, an issue arose, as
  described below, with respect to certain transactions involving Hawkeye and
  Bennett.

       During the period of negotiations with Commercial in late March 1996,
  Hawkeye had approximately $1.8 million invested in the Bennett Funding Asset.
  Approximately 10,000 investors and 200 financial institutions nationwide had
  similar investments or lending relationships with Bennett.  Bennett filed for
  Chapter 11 bankruptcy protection on March 29, 1996 after the principals of the
  company were charged with various criminal offenses relating to the leasing
  transactions.  Upon the filing of the Bennett bankruptcy case, Hawkeye's
  Bennett Funding Asset became nonperforming.

       Based on available information regarding the status of Hawkeye's interest
  in the Bennett Funding Asset, management of Heritage believed that it had a
  reasonable expectation of recovery with respect to some or all of the
  projected value of the Bennett Funding Asset.  However, Commercial sought a
  downward price adjustment in light of the pending Bennett bankruptcy
  proceeding and questions regarding the adequacy of Hawkeye's lien priority to
  the leases collateralizing the Bennett Funding Asset.

       Over the course of negotiations, which continued through April and May
  1996, the parties considered several alternative structures whereby Heritage
  stockholders would have the opportunity to realize the value of the Bennett
  Funding Asset.  Ultimately, the parties agreed to structure the Merger
  Consideration in the manner detailed in this Prospectus/Proxy Statement.  Over
  the same period, the parties continued to negotiate the other key terms and
  conditions of the definitive agreement.  Throughout the negotiations, the
  Heritage Board periodically reviewed with management the status of the
  negotiations and provided its views on key issues.  In addition,
  representatives of Heritage conducted a due diligence examination of
  Commercial since Commercial Common Stock would be issued as consideration to
  Heritage stockholders under the terms of the proposed transaction.

       On May 14, 1996, the Heritage Board met to consider the proposed
  definitive agreement with Commercial, including the proposed resolution of
  issues related to the Bennett Funding Asset.  At the meeting, Breyer & Aguggia
  reviewed the Board's fiduciary obligations and Hovde reviewed the proposed
  Merger Consideration and the collar and price adjustments relative to the
  Merger Consideration in the event of potential movements in the price of
  Commercial Common Stock.  Hovde also specifically reviewed the relationship
  between the Bennett Funding Asset and the Merger Consideration.  The Board
  also extensively reviewed with legal counsel and with its financial advisor
  the proposed terms of the transaction compared to other comparable
  transactions; financial information regarding Commercial; the results of a due
  diligence analysis of Commercial; the proposed treatment of Hawkeye employees;

                                       20

  and alternative valuations of Heritage.  The Board also reviewed the prospects
  for realizing comparable stockholder returns by remaining an independent
  entity.  Finally, the Board reviewed  and discussed the text of Hovde's
  proposed opinion to the effect that the Merger Consideration (without any
  value attributed to the Bennett Funding Asset), as of such date, was fair,
  from a financial point of view, to the holders of Heritage Common Stock.  The
  Board also reviewed the anticipated tax consequences of the transaction.

       On May 16, 1996, the Heritage Board met again, discussed the proposed
  transaction in detail, reviewed the text of Hovde's opinion dated May 16, 1996
  and unanimously approved the Merger Agreement.  The Board authorized
  management, in consultation with legal counsel, to enter into and carry out
  the Merger Agreement.

  Reasons for the Merger and Recommendation of the Heritage Board of Directors

       Heritage's Board of Directors believes that the terms of the Merger
  Agreement, which are the product of arm's length negotiations between
  representatives of Heritage and Commercial, are fair and in the best interests
  of Heritage and its stockholders.  In the course of reaching its
  determination, the Heritage Board consulted with legal counsel with respect to
  its legal duties, the terms of the Merger Agreement and the issues related
  thereto; with its financial advisor with respect to the financial aspects and
  fairness of the transaction; and with senior management regarding, among other
  things, operational matters.  It should be noted that there is no affiliation
  between any of the directors and officers of the respective companies.

       In reaching its determination to approve the Merger Agreement, the
  Heritage Board considered all factors it deemed material, which included the
  following:

       (a) The Heritage Board analyzed information with respect to the financial
  condition, results of operations, cash flow, business and prospects of
  Heritage.  In this regard, the Heritage Board analyzed the options of selling
  Heritage or continuing on a stand-alone basis.  The range of values on a sale
  of control basis were determined generally to exceed the present value of
  Heritage shares on a stand-alone basis under business strategies that could be
  reasonably implemented by Heritage.

       (b) The Heritage Board considered the written opinion of Hovde that, as
  of May 16, 1996, the Merger Consideration (without any value attributed to the
  Bennett Funding Asset) to be received by holders of Heritage Common Stock
  pursuant to the Merger Agreement was fair to Heritage stockholders from a
  financial point of view. See "-- Financial Advisor and Opinion of Financial
  Advisor."

       (c) The Heritage Board considered the current operating environment,
  including, but not limited to, the continued consolidation and increasing
  competition in the banking and financial services industries, the prospect for
  further changes in these industries, the controversy pertaining to the
  BIF/SAIF deposit insurance premium differential and federal regulatory agency
  consolidation and the importance of being able to capitalize on developing
  opportunities in these industries.

       (d) The Heritage Board considered the other terms of the Merger Agreement
  and exhibits, including the fact that the merger would, to the extent that the
  consideration consisted of Commercial Common Stock, generally be income tax
  free to Heritage stockholders.  In addition, the Board considered the fact
  that the structure of the Merger Consideration would offer Heritage
  stockholders the opportunity to maximize the value of the Bennett Funding
  Asset while, at the same time, permit the sale of Heritage at a significant
  premium.  The Heritage Board also considered the likelihood that another
  acquiror would treat the Bennett Funding Asset in a manner more favorable to
  Heritage stockholders and concluded that the approach to the Bennett Funding
  Asset set forth in the Merger Agreement had been negotiated fully and in good
  faith by the parties and was in the best interest of Heritage stockholders.

                                       21
<PAGE>
 
       (e)  The Heritage Board considered detailed financial analyses, pro forma
  and other information with respect to Heritage and Commercial discussed by
  Hovde, as well as the Heritage Board's own knowledge of Heritage, Commercial
  and their respective businesses.  In this regard, the latest publicly-
  available financial and other information for Heritage and Commercial were
  analyzed, including a comparison to publicly-available financial and other
  information for other similar savings institutions.  The Board also considered
  the relative liquidity of Heritage Common Stock and Commercial Common Stock.

       (f)  The Heritage Board considered the value of Heritage continuing as a
  stand-alone entity compared to the effect of Heritage combining with
  Commercial in light of the factors summarized above and the current economic
  and financial environment, including, but not limited to, other possible
  strategic alternatives.

       (g)  The Heritage Board considered the likelihood of the Merger being
  approved by the appropriate regulatory authorities, including factors such as
  market share analyses, Commercial's Community Reinvestment Act rating at that
  time and the estimated pro forma financial impact of the Merger on Commercial.

       (h)  The Heritage Board considered the fact that the Merger Agreement
  prohibits Heritage from initiating, soliciting or encouraging discussions with
  third parties relating to alternative transactions and requires the payment of
  a termination fee of $1.0 million to Commercial in certain events, and the
  fact that Commercial required such provisions as a condition to entering into
  the Merger Agreement.

       The foregoing discussion of the information and factors considered by the
  Heritage Board is not intended to be exhaustive, but constitutes the material
  factors considered by the Heritage Board.  In reaching its determination to
  approve and recommend the Merger Agreement, the Heritage Board did not assign
  any relative or specific weights to the foregoing factors, and individual
  directors may have weighed factors differently.  After deliberating with
  respect to the Merger and the other transactions contemplated by the Merger
  Agreement, considering, among other things, the matters discussed above and
  the opinion of Hovde referred to above, the Heritage Board unanimously
  approved and adopted the Merger Agreement and the transactions contemplated
  thereby as being in the best interests of Heritage and its stockholders.
   
       FOR THE REASONS SET FORTH ABOVE, THE HERITAGE BOARD HAS UNANIMOUSLY
  APPROVED THE MERGER AGREEMENT AS ADVISABLE AND IN THE BEST INTERESTS OF
  HERITAGE AND HERITAGE STOCKHOLDERS AND RECOMMENDS THAT THE STOCKHOLDERS OF
  HERITAGE VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT.
                ---                                      

  Financial Advisor and Opinion of Financial Advisor

       Hovde has delivered to the Heritage Board its opinion that, based upon
  and subject to the various considerations set forth in its written opinion
  dated May 16, 1996, the Merger Consideration is fair from a financial point of
  view to the stockholders of Heritage as of such date.  Such opinion was
  updated as of the date hereof.  In requesting Hovde's advice and opinion, no
  limitations were imposed by Heritage upon Hovde with respect to the
  investigations made or procedures followed by it in rendering its opinion.
      
       The full text of the opinion of Hovde, dated August 21, 1996, which
  describes the procedures followed, assumptions made, matters considered and
  limitations on the review undertaken, is attached hereto as Annex B.
  Stockholders of Heritage should read this opinion in its entirety.     

       HOVDE'S OPINION IS DIRECTED ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT
  OF VIEW, OF THE MERGER CONSIDERATION, AND DOES NOT CONSTITUTE A RECOMMENDATION
  TO ANY STOCKHOLDER OF HERITAGE AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE
  SPECIAL MEETING.  THE SUMMARY OF THE OPINION OF HOVDE SET FORTH IN THIS
  PROSPECTUS/PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
  FULL TEXT OF SUCH OPINION.

                                       22

       The following is a brief summary of the analyses performed by Hovde in
  connection with its fairness opinion.

       During the course of its engagement, and as a basis for arriving at its
  opinion, Hovde reviewed and analyzed material bearing upon the financial and
  operating condition of Commercial and Heritage and material prepared in
  connection with the Merger, including, among other things, the following:  (i)
  the Merger Agreement; (ii) certain publicly available information concerning
  Heritage and Commercial, including the consolidated statements of financial
  condition of Heritage and Commercial for each of the three fiscal years ended
  June 30, 1995, and the statements of financial condition and results of
  operations of Heritage and Commercial for the subsequent quarterly periods
  through  March 31, 1996; (iii) the nature and terms of recent acquisition and
  merger transactions involving thrift institutions and thrift holding companies
  that Hovde considered reasonably similar to Heritage in size, financial
  character, operating character, historical performance and geographic market;
  and (iv) financial and other information provided to Hovde by the management
  of Commercial and Heritage.  Hovde conducted meetings with members of senior
  management of Heritage and Commercial for purposes of reviewing the future
  prospects of Heritage and Commercial.  Hovde also took into account its
  experience in other transactions, as well as its knowledge of the commercial
  banking and thrift industries and its general experience in securities
  valuations.

       In rendering its opinion, Hovde assumed, without independent
  verification, the accuracy and completeness of the financial and other
  information and has relied upon the accuracy of the representations of the
  parties contained in the Merger Agreement.  Hovde has not made any independent
  evaluation or appraisal of any properties, assets or liabilities of Heritage.
  Hovde assumed and relied upon the accuracy and completeness of the publicly
  available and other financial and other information provided to it, relied
  upon the representations and warranties of Commercial and Heritage made
  pursuant to the Merger Agreement, and did not independently attempt to verify
  any of such information.

       In connection with its opinion, Hovde performed various analyses with
  respect to Heritage.  The following is a brief summary of such analyses,
  certain of which were presented to the Heritage Board by Hovde on or before
  May 16, 1996.

       Analysis of the Merger Consideration.  Hovde reviewed the value of the
  Merger Consideration to be received by each Heritage stockholder.  Hovde
  calculated that the Merger Consideration equated to approximately 159.88% of
  Heritage's fully diluted tangible book value at March 31, 1996, a multiple of
  approximately 27.2 times Heritage's earnings for the fiscal year ended June
  30, 1995, a multiple of approximately 15.7 times Heritage's earnings for the
  12 months ended March 31, 1996, and a premium to core deposits of
  approximately 5.25%.  These multiples exclude the value of any contingent
  proceeds which may be received by the Heritage stockholders in the future in
  the event of recoveries of the Bennett Funding Asset, and further do not
  reflect the 100% reserve by Heritage of the Bennett Funding Asset in the
  quarter and fiscal year ended June 30, 1996, and the attendant reduction in
  Heritage's book value per share and earnings per share.

       Summary of Proposals.  Hovde summarized the sales process, the parties
  contacted and the level of interest expressed by each party, including the
  value of the aggregate consideration offered to the stockholders of Heritage.

       Hovde also compared the significant terms of the Commercial proposal to
  that of the other institutions submitting proposals, including the value of
  the consideration offered.   This analysis showed, among other things, that
  the value of the Commercial proposal of $116.61 per share of Heritage Common
  Stock, plus the contingent proceeds of up to $5.83 per share based upon
  potential future recoveries of the Bennett Funding Asset, was considered
  higher than the value per share offered by the other prospective acquirors,
  especially given that 80% of the consideration was in the form of a tax-
  deferred, common stock exchange.  Hovde examined the trading price and volume
  for Commercial Common Stock and the relationship between the trading
  characteristics of the common stocks of the other companies, as well as to a
  peer group of comparable companies.

                                       23

       Analysis of Selected Mergers.  As part of its analysis, Hovde reviewed
  three sets of mergers:  (i) selected mergers involving thrifts headquartered
  anywhere in the United States completed since June 30, 1993 and announced on
  or before May 1, 1996 in which the total deal value was between $20 million
  and $30 million (the "Nationwide Mergers"); (ii) selected mergers involving
  thrifts headquartered in the Midwest announced between January 1, 1993 and May
  1, 1996 in which the total deal value was between $20 million and $30 million
  (the "Midwestern Mergers"); and (iii) all mergers involving thrifts
  headquartered in Iowa announced since January 1, 1992 (the "Iowa Mergers").
  The Nationwide Mergers consisted of 37 mergers involving thrifts headquartered
  anywhere in the United States; the Midwestern Mergers consisted of 18 mergers
  of thrifts headquartered in the Midwest; and the Iowa Mergers consisted of
  nine thrifts headquartered in Iowa.  For each transaction, Hovde calculated
  the multiple of the offer value to the acquired company's:  (i) earnings per
  share ("EPS") for the twelve months preceding ("LTM") the announcement date of
  the transaction; (ii) book value per share; (iii) tangible book value per
  share; and (iv) the tangible book premium to core deposits.

       The calculations for the Nationwide Mergers yielded a range of multiples
  of offer value to LTM EPS of 3.7 times to 33.5 times, with an average of 16.0
  times and a median of 14.6 times; a range of multiples of offer value to book
  value of 0.83 times to 1.98 times, with an average of 1.51 times and a median
  of 1.51 times; a range of multiples of offer value to tangible book value of
  1.02 times to 1.98 times, with an average of 1.53 times and a median of 1.53
  times; and a range of tangible book premium to core deposits of  0.17% to
  15.49%, with an average of 6.81% and a median of 5.85%.

       The calculations for the Midwestern Mergers yielded a range of multiples
  of offer value to LTM EPS of 5.3 times to 33.5 times, with an average of 17.8
  times and a median of 15.7 times; a range of multiples of offer value to book
  value of 1.13 times to 1.98 times, with an average of 1.46 times and a median
  of 1.39 times; a range of multiples of offer value to tangible book value of
  1.14 times to 1.98 times, with an average of 1.47 times and a median of 1.39
  times; and a range of tangible book premium to core deposits of 1.99% to
  15.49%, with an average of 7.08% and a median of 5.79%.

       The calculations of the Iowa Mergers yielded a range of multiples of
  offer value to LTM EPS of 10.1 times to 33.5 times, with an average of 16.6
  times and a median of 13.5 times; a range of multiples of offer value to book
  value of 1.08 times to 1.71 times, with an average of 1.36 times and a median
  of 1.36 times; a range of multiples of offer value to tangible book value of
  1.08 times to 1.71 times, with an average of 1.38 times and a median of 1.36
  times; and a range of tangible book premium to core deposits of 2.17% to
  9.05%, with an average of 5.80% and a median of 5.91%.

       Hovde compared these multiples with the corresponding multiples for the
  Merger, valuing the shares of Commercial Common Stock that would be received
  pursuant to the Merger Agreement at $116.61 per share of Heritage Common
  Stock.  In calculating the multiples for the Merger, Hovde used Heritage's EPS
  for the fiscal year ended June 30, 1995, and the 12 months ended March 31,
  1996, book value per share and tangible book value per share as of March 31,
  1996, and Hovde calculated that Heritage's fiscal year EPS, LTM EPS, book
  value per share, tangible book value per share and tangible book premium to
  core deposits were 27.2 times, 15.7 times, 1.6 times, 1.6 times, and 5.25%,
  respectively.  These multiples exclude the value of any contingent proceeds
  which may be received by the Heritage stockholders in the future in the event
  of recoveries of the Bennett Funding Asset, and further do not reflect the
  100% reserve by Heritage of the Bennett Funding Asset in the quarter and
  fiscal year ended June 30, 1996, and the attendant reduction in Heritage's
  book value per share and earnings per share.

       No company or transaction used in the above analysis as a comparison is
  identical to Heritage,  Commercial or the Merger.  Accordingly, an analysis of
  the results of the foregoing is not mathematical; rather, it involves complex
  considerations and judgments concerning differences in financial and operating
  characteristics of the companies and other facts that could affect the public
  trading value of the companies to which they are being compared.

                                       24
<PAGE>
 
       Contribution Analysis.  Hovde prepared a contribution analysis showing
  percentages of assets, deposits, common equity, and 1995 and estimated 1996
  net income contributed to the combined company on a pro forma basis by
  Heritage and Commercial.  This analysis showed, assuming Commercial's Common
  Stock price was at $37.00 per share, that Heritage, as of March 31, 1996,
  would contribute 2.73% of pro forma consolidated total assets, 3.56% of
  deposits, 3.39% of common equity, 2.91% of 1995 net income, and 2.54% of
  estimated 1996 net income (excluding the 100% reserve by Heritage in the
  quarter and fiscal year ended June 30, 1996, in connection with the Bennett
  Funding Asset).  The stockholders of Heritage would own approximately 3.64% of
  the pro forma Common Shares outstanding of Commercial, assuming Commercial's
  Common Stock price was at $37.00 per share, based upon a price of $116.61 per
  share of Heritage Common Stock and excluding Heritage's outstanding stock
  options.

       Financial Implications to Heritage Stockholders.  Hovde prepared an
  analysis of the financial implications of the Commercial offer to a Heritage
  stockholder.  This analysis indicated that on a pro forma equivalent basis, at
  a $116.61 price per share of Heritage Common Stock with Commercial Common
  Stock trading at $37.00 per share, a stockholder of Heritage would achieve an
  increase in earnings per share of initially 43.3% in 1996 increasing to 84.1%
  in 2000, a decrease in per share dividends of initially 68.5% in  1996 but
  decreasing to 22.3% in 2000, and an increase in fully diluted book value per
  share of initially 13.1% in 1996 and increasing to 44.9% in 2000, as a result
  of the consummation of the Merger.

       Comparative Stockholder Returns.  Hovde presented an analysis of
  comparative theoretical stockholder returns in several scenarios, including
  Heritage remaining independent, Heritage being acquired in 2001 and Heritage
  being acquired by Commercial at $116.61 per share.  This analysis, which was
  based on the net present value of projected dividend streams and projected
  1996 common stock valuations (using current price-to-earnings multiples),
  indicated total stockholder returns of 9.37% if Heritage remained independent,
  22.45% for a merger in 2001 on the terms specified in the following paragraph,
  and 27.21% based on the acceptance of the offer from Commercial at $116.61 per
  share with the Commercial Common Stock trading at an assumed price of $37.00
  per share.

       Discounted Cash Flow Analysis.  Hovde performed a discounted cash flow
  analysis to determine a present value per share of Heritage Common Stock
  assuming Heritage continued to operate as a stand-alone entity and was
  acquired at a later date.  This present value was determined by projecting
  Heritage's after-tax net income for the five fiscal years ended June 30, 1996
  through 2000.  Projected net income was determined through consultation with
  Heritage's management and generally included aggressive growth in assets (5%
  per year from 1996 through 2000), as well as progressively higher net income
  as a percent of average assets (increasing from .82% for 1996 to 1.01% for the
  twelve months ended June 30, 2000).  "Terminal value" per share of Heritage
  Common Stock was determined by applying a price to earnings multiple of 14.6
  times (being the median price to earnings multiple for Nationwide Mergers and
  acquisitions of similar-sized transactions) against Heritage's projected
  earnings at June 30, 2000.  The present value of the terminal value was then
  determined using an annual discount rate of 13%.  The above calculations
  resulted in a present value per fully diluted share of Heritage Common Stock
  of $105.58 per share.

       Although the summary set forth above does not purport to be a complete
  description of the analysis performed by Hovde, the material analyses
  performed by Hovde in rendering its opinion has been summarized above.
  However, the preparation of a fairness opinion is not necessarily susceptible
  to partial analysis or summary description.  Hovde believes that its analyses
  and the summary set forth above must be considered as a whole and that
  selecting portions of its analyses, without considering all factors and
  analysis, would create an incomplete view of the process underlying the
  analyses by which Hovde reached its opinion.  In addition, Hovde may have
  given various analyses more or less weight than other analyses, but no
  analysis was given materially more weight than any other analysis.  Also,
  Hovde may have deemed various assumptions more or less probable than other
  assumptions so that the ranges of valuations resulting from any particular
  analysis described above should not be taken to be Hovde's view of the actual
  value of Heritage or the combined company.

                                       25
<PAGE>
 
       In performing its analyses, Hovde made numerous assumptions with respect
  to industry performance, general business and economic conditions and other
  matters, many of which are beyond the control of Heritage and Commercial.  The
  analyses performed by Hovde are not necessarily indicative of actual value or
  actual future results, which may be significantly more or less favorable than
  suggested by such analyses.  Such analyses were prepared solely as part of
  Hovde's analyses of the fairness of the Merger Consideration, from a financial
  point of view, to the holders of Heritage Common Stock.  The analyses do not
  purport to be an appraisal or to reflect the prices at which a company might
  actually be sold or the prices at which any securities may trade at the
  present time or at any time in the future.  Hovde used in its analyses various
  projections of future performance prepared by the management of Heritage.  The
  projections are based on numerous variables and assumptions which are
  inherently unpredictable and must be considered not certain of occurrence as
  projected.  Accordingly, actual results could vary significantly from those
  assumed in the projections and any related analysis.  Hovde's opinion does not
  address the relative merits of the Merger as compared to any other business
  combination in which Heritage might engage.  In addition, as described above,
  Hovde's opinion to the Heritage Board was one of several factors taken into
  consideration by the Heritage Board in making its determination to approve the
  Merger Agreement.

       Based upon the foregoing analyses and other investigations and
  assumptions set forth in its opinions without giving specific weightings to
  any one factor or comparison, Hovde determined that the Merger Consideration
  was fair from a financial point of view to the stockholders of Heritage.
  Hovde's fairness opinion does not take into account any adjustment to the
  Merger Consideration that may be provided for in the Merger Agreement.

       THE SUMMARY OF THE PRESENTATION BY HOVDE TO THE HERITAGE BOARD AS SET
  FORTH ABOVE DOES NOT PURPORT TO BE A COMPLETE DESCRIPTION OF SUCH
  PRESENTATION.  THE PREPARATION OF A FAIRNESS OPINION INVOLVES VARIOUS
  DETERMINATIONS AS TO THE MOST APPROPRIATE AND RELEVANT METHODS OF FINANCIAL
  ANALYSES AND THE APPLICATION OF THOSE METHODS TO THE PARTICULAR CIRCUMSTANCES,
  AND, THEREFORE, SUCH AN OPINION IS NOT READILY SUSCEPTIBLE TO SUMMARY
  DESCRIPTION.  FURTHERMORE, IN ARRIVING AT ITS OPINION, HOVDE DID NOT ATTRIBUTE
  ANY PARTICULAR WEIGHT TO ANY ANALYSIS OR FACTOR CONSIDERED BY IT, BUT RATHER
  MADE QUALITATIVE JUDGMENTS AS TO THE SIGNIFICANCE AND RELEVANCE OF EACH
  ANALYSIS AND FACTOR.  ACCORDINGLY, HOVDE BELIEVES THAT ITS ANALYSES AND THE
  SUMMARY SET FORTH ABOVE MUST BE CONSIDERED AS A WHOLE AND THAT SELECTING
  PORTIONS OF ITS ANALYSES, WITHOUT CONSIDERING ALL FACTORS AND ANALYSES, COULD
  CREATE AN INCOMPLETE VIEW OF THE PROCESS UNDERLYING THE ANALYSES SET FORTH IN
  ITS REPORT TO THE HERITAGE BOARD AND ITS FAIRNESS OPINION.  IN PERFORMING ITS
  ANALYSES, HOVDE MADE NUMEROUS ASSUMPTIONS WITH RESPECT TO INDUSTRY
  PERFORMANCE, GENERAL BUSINESS AND ECONOMIC CONDITIONS AND OTHER MATTERS, MANY
  OF WHICH ARE BEYOND THE CONTROL OF COMMERCIAL OR HERITAGE.  THE ANALYSES
  PERFORMED BY HOVDE ARE NOT NECESSARILY INDICATIVE OF ACTUAL VALUES OR ACTUAL
  FUTURE PERFORMANCE.

       Hovde will receive a fee of approximately $422,000 for services rendered
  in connection with advising Heritage regarding the Merger Agreement, including
  the fairness opinion, plus reimbursement of out-of-pocket expenses.  As of the
  date of this Prospectus/Proxy Statement, Hovde has received $105,640 of such
  fee.

  Conversion of Heritage Common Stock

       Exchange Ratio.  Each share of Heritage Common Stock issued and
  outstanding at the Acquisition Merger Effective Time (other than (i)
  Dissenting Shares or  shares owned or held by Heritage or its subsidiaries
  other than in a 401(k) plan or in a fiduciary capacity) will be converted into
  and represent solely the right to receive (a) $18.73 in cash (subject to
  increase in connection with the Bennett Funding Asset) and (b) a number of
  shares of Commercial Common Stock as follows:  (i) if the Average NYSE Closing
  Price is equal to or greater than $33.50 but equal to or less than $36.00, the
  Exchange Ratio shall be 2.719 shares of Commercial Common Stock; (ii) if the
  Average NYSE Closing Price is less than $41.00 but greater than $36.00, the
  Exchange Ratio shall be that number of shares

                                       26
<PAGE>
 
  of Commercial Common Stock equal to the quotient that results by dividing
  97.88 by the Average NYSE Closing Price; (iii) if the Average NYSE Closing
  Price is equal to or greater than $41.00 but equal to or less than $45.00, the
  Exchange Ratio shall be 2.387 shares of Commercial Common Stock; (iv) if the
  Average NYSE Closing Price is greater than $45.00 but less than $47.50, the
  Exchange Ratio shall be that number of shares of Commercial Common Stock equal
  to the quotient that results by dividing 107.43 by the Average NYSE Closing
  Price; (v) if the Average NYSE Closing Price is equal to or grater than $47.50
  but less than or equal to $50.00, then the Exchange Ratio shall be 2.262
  shares of Commercial Common Stock; and (vi) if the Average NYSE Closing Price
  is greater than $50.00, then the Exchange Ratio shall be equal to the quotient
  that results by dividing 113.08 by the Average NYSE Closing Price.
      
       The cash consideration to be received by Heritage stockholders in the
  Merger may be increased depending on the extent to which the Bennett Funding
  Asset recovers value prior to or for a certain period of time following the
  Merger. Pursuant to the Merger Agreement, Heritage has agreed that prior to
  the Merger, it will either (i) sell the Bennett Funding Asset in its entirety,
  or (ii) establish a specific loan loss reserve equal to the carrying value of
  the Bennett Funding Asset on Heritage's accounting records. As of this
  Prospectus/Proxy Statement, the Bennett Funding Asset has not yet been sold.
  However, as of June 30, 1996, Heritage established a specific loan loss
  reserve of $1.8 million for the entire amount of the Bennett Funding Asset. If
  the Bennett Funding Asset is subsequently sold prior to the effective time of
  the Merger, the cash portion of the Merger Consideration will be increased by
  64% of the recovery recognized from such sale which represents the recovered
  amount less the agreed upon tax impact of 36%. Commercial and Heritage have
  also agreed that, following the Merger and until the earlier of September 30,
  1999 or the full collection of the Bennett Funding Asset, 64% of any cash
  proceeds (net of certain expenses) received from the sale or collection of the
  Bennett Funding Asset will be distributed to those individuals who were
  stockholders of Heritage immediately prior to the Merger. For additional
  information see " -- Bennett Funding Asset." Based on the closing price of
  Commercial Common Stock on the NYSE on August 12, 1996, of $38.25 per share
  and assuming no value is recovered in connection with the Bennett Funding
  Asset, each share of Heritage Common Stock would be exchanged for $18.73 in
  cash and 2.559 shares of Commercial Common Stock.    

       No Fractional Shares.  No fractional shares of Commercial Common Stock
  will be issued in the Merger.  Instead, cash will be paid in lieu of any
  fractional share interests of Commercial Common Stock resulting from the
  Merger.  No dividend or distribution with respect to Commercial Common Stock
  will be payable on or with respect to any fractional share interests, and no
  fractional share interest will entitle the owner thereof to vote or to any
  other rights of a stockholder of Commercial.  The applicable cash value of
  each fractional share interest will be equal to the product of such fraction
  multiplied by the Average NYSE Closing Price for shares of Commercial Common
  Stock.
      
       Exchange of Heritage Stock Certificates. Prior to the Acquisition Merger
  Effective Time, Commercial will appoint an exchange agent (the "Exchange
  Agent") to effect the exchange of stock certificates in connection with the
  Acquisition Merger. As soon as practicable after the Acquisition Merger
  Effective Time, the Exchange Agent will send a notice and transmittal form to
  each Heritage stockholder of record at such date whose Heritage Common Stock
  has been converted into cash and 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 Heritage Common Stock in exchange for cash and for new certificates
  of Commercial Common Stock. Promptly following receipt of such notice and
  transmittal form, holders of Heritage Common Stock certificates should
  surrender their certificates in accordance with the specified procedures. Upon
  surrender, each Heritage Common Stock certificate will be cancelled. The same
  procedures will apply to holders of certificates representing shares of
  Hawkeye common stock that were not exchanged for certificates of Heritage
  Common Stock upon the formation of Heritage in 1990.     

       Until surrendered, certificates that prior to the Acquisition Merger
  Effective Time represented outstanding shares of Heritage Common Stock or, if
  applicable, Hawkeye common stock (other than Dissenting Shares) will be deemed
  for all corporate purposes to evidence the right to receive cash and that
  number of shares of Commercial Common Stock into which such shares of Heritage
  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

                                       27
<PAGE>
 
  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, cash paid
  in lieu of fractional shares or the cash portion of the consideration to be
  received in the Merger.

       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 owed.  In the event any certificate for
  Heritage Common Stock has been lost, stolen or destroyed, the Exchange Agent
  will issue, in exchange for such certificate, upon the making of an affidavit
  of that fact by the holder thereof, the Merger Consideration; provided,
  however, that Commercial may require the owner of such certificate to deliver
  a bond in such sum as it may direct as indemnity against any claim that may be
  made against Commercial, Heritage, the Exchange Agent or any other party.

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

  Treatment of Heritage Stock Options

       Immediately prior to the Acquisition Merger Effective Time, each holder
  of an option outstanding under the Heritage Option Plan, whether or not the
  option is then exercisable, shall, in cancellation of such option, (such
  cancellation to be reflected in a written agreement) receive from Heritage per
  share of Heritage Common Stock subject to such option a cash payment in an
  amount equal to the per share value of the Merger Consideration, less the
  exercise price of such option, net of any cash which must be withheld under
  federal and state tax requirements.  Immediately thereafter, Heritage will
  cancel each such option.

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

  Bennett Funding Asset
      
       As of the date of this Prospectus/Proxy Statement, Heritage had
  approximately $1.8 million invested in the Bennett Funding Asset. Pursuant to
  the terms of the Merger Agreement, Heritage has agreed that it will either (i)
  sell the Bennett Funding Asset in its entirety or (ii) establish a specific
  loan loss reserve equal to the carrying value of the Bennett Funding Asset on
  Heritage's accounting records. If the Bennett Funding Asset is sold prior to
  the Acquisition Merger Effective Time, the cash portion of the Merger
  Consideration will be increased by 64% of the recovery recognized from such
  sale which represents the recovered amount less the agreed upon tax impact of
  36%. If the Bennett Funding Asset is not sold prior to the Acquisition Merger
  Effective Time, such asset will be managed pursuant to the terms of the Asset
  Management Agreement (the "Asset Management Agreement") entered into by the
  parties concurrent with the execution of the Merger Agreement and amended on
  August 21, 1996. Any recovered value of the Bennett Funding Asset during the
  term of the Asset Management Agreement (net of certain expenses) will be
  disbursed to those parties who were stockholders of Heritage immediately prior
  to the Acquisition Merger Effective Time.    

       Pursuant to the Asset Management Agreement, effective upon the
  Acquisition Merger Effective Time, the Bennett Funding Asset will be
  administered by a committee (the "Committee") consisting of three individuals,
  two of whom shall be individuals appointed by Hawkeye and the other of whom
  will be the Chairman of the Credit Committee of the Bank.  The Committee's
  duties will consist of using its good faith efforts to collect any and all
  value recoverable on the Bennett Funding Asset through the sale thereof or
  otherwise, and to distribute such funds, net of certain expenses, to the
  former Heritage stockholders.  The Bennett Funding Asset will be directly
  managed by such individuals designated by the Bank who serve in the Bank's 
  corporate credit group (the "Managers").

                                       28
<PAGE>
 
  Pursuant to the Asset Management Agreement, however, the Bank's obligation to
  provide the Managers may be terminated at the sole option of the Bank at any
  time beginning one year after the Acquisition Merger Effective Time if the
  hours actually spent by one or more Managers exceeds 160 hours within a six-
  month period. In the event of such early termination, the Committee may
  appoint another person or entity to manage the Bennett Funding Asset and seek
  to collect the value on or relating to the Bennett Funding Asset upon such
  terms and conditions as the Committee may determine; provided that in no event
  may the term of such alternative engagement exceed the term of the Asset
  Management Agreement. The Bank will be compensated for the time spent by such
  Managers in collecting the Bennett Funding Asset. Although the Managers will
  be directly responsible for the management of the asset, certain decisions
  will be reserved for the Committee.
    
       Under the Asset Management Agreement, distributions of proceeds allocable
  to Heritage stockholders from the collection of the Bennett Funding Asset, net
  of all related expenses, will be made on an annual basis, beginning on or
  about the first anniversary of the Acquisition Merger Effective Time.
  Distributions will be made semi-annually in the event the proceeds to be 
  distributed to Heritage stockholders (net of expenses and a reserve necessary
  to pay the expenses reasonably expected to be incurred in the 30 days
  following the distribution) exceed $100,000. The Asset Management Agreement
  provides that it will terminate upon the earlier of (i) the full collection of
  the Bennett Funding Asset, through sale or otherwise, and the distribution of
  the proceeds collected therefrom to the former stockholders of Heritage, or
  (ii) September 30, 1999; provided, however, that this date may be extended to
  December 31, 1999 if in the reasonable good faith and unanimous opinion of the
  Committee, immediately prior to September 30, 1999, further collection efforts
  are warranted. All funds, if any, received from the collection of the Bennett
  Funding Asset subsequent to the termination of the Asset Management Agreement
  will be for the benefit of the Bank.     

       For additional information, see the Asset Management Agreement which is
  attached hereto as part of Annex A.

  Dissenters' Rights of Appraisal
      
       Under provisions of Division XIII of the IBCA and in accordance with the
  procedures set forth in Part B thereof, a copy of which is attached to this
  Prospectus/Proxy Statement as Annex C, any holder of record or beneficial
  holder of Heritage Common Stock has the right to dissent from the Merger and
  demand payment of the fair value of his or her shares in cash. Any stockholder
  who wishes to assert dissenters' rights must file a written notice of his or
  her intent to demand payment with Heritage, Attention: John F. Peterson,
  President, 715 8th Street, Boone, Iowa 50036, before the vote on the Merger
  Agreement is taken at the Special Meeting and must refrain from voting in
  favor of the Merger Agreement. A PROXY OR VOTE AGAINST THE MERGER AGREEMENT
  WILL NOT, BY ITSELF, BE REGARDED AS A WRITTEN NOTICE OF INTENT TO DEMAND
  PAYMENT FOR PURPOSES OF ASSERTING DISSENTERS' RIGHTS.     

       A record holder of Heritage Common Stock may assert dissenters' rights as
  to fewer than all shares registered in that stockholder's name only if the
  holder dissents with respect to all shares beneficially owned by any one
  person and notifies Heritage in writing of the name and address of each person
  on whose behalf the stockholder asserts dissenters' rights.

       A beneficial stockholder may assert dissenters' rights as to shares held
  on the stockholders's behalf only if, in addition to meeting the other
  requirements to dissent, the beneficial stockholder (i) submits to Heritage
  the record stockholder's written consent to the dissent not later than the
  time the beneficial stockholder asserts dissenters' rights and (ii) asserts
  dissenters' rights with respect to all shares of which such stockholder is the
  beneficial stockholder or over which that beneficial stockholder has power to
  direct the vote.

       If the Merger Agreement is approved by the requisite vote of holders of
  Heritage Common Stock, Heritage is required to send a notice to all dissenting
  stockholders containing a form for demanding payment and payment demand and
  certificate surrender information (the "Dissenters' Notice") within 10 days
  after such approval.  The date (the "Payment Demand Date") specified by
  Heritage for receiving payment demand (the "Payment Demand") from dissenting
  stockholders will be not less than 30 nor more than 60 days after the date on
  which the Dissenters' Notice was sent. Upon receipt of the Dissenters' Notice,
  each dissenting stockholder must return his or her Payment

                                       29
<PAGE>
 
  Demand and certificates no later than the Payment Demand Date as provided in
  the notice and certify whether he or she acquired beneficial ownership of the
  shares prior to the first public announcement of the terms of the Merger on
  May 16, 1996.

       If the Acquisition Merger is effected within 60 days after the Payment
  Demand Date, Heritage will pay each dissenting stockholder who properly
  complied with the statutory requirements the amount that Heritage estimates to
  be the fair value of such dissenting stockholder's shares, plus accrued
  interest from the Acquisition Merger Effective Time.

       If the Acquisition Merger is not effected within 60 days of the Payment
  Demand Date, Heritage will return all deposited certificates to any dissenting
  stockholders.  If the Acquisition Merger is thereafter effected, Heritage will
  send a new Dissenters' Notice within 10 days of effecting the Acquisition
  Merger and repeat the payment demand procedures.

       If any dissenter is dissatisfied with Heritage's payment or offer, as the
  case may be, such dissenting stockholder may notify Heritage in writing of his
  or her own estimate of the fair value of his or her shares and the amount of
  interest due and demand payment of such amount.  This demand must be made by
  the dissenting stockholder within 30 days after Heritage made or offered
  payment for the dissenter's shares.  Heritage may either accept such
  dissenting stockholder's estimate of fair value or commence a proceeding in
  the Iowa District Court of Boone County to determine the fair value of the
  shares of all dissenting stockholders whose own estimates of fair value are
  not accepted by Heritage.

       In the event any holder of Heritage Common Stock fails to perfect his or
  her rights to dissent by failing to comply strictly with the applicable
  statutory requirements, the stockholder will be bound by the terms of the
  Merger Agreement and will not be entitled to payment for his or her shares
  under the IBCA.  Any holder of Heritage Common Stock who wishes to object to
  the transaction and demand payment in cash for his or her shares should
  consider consulting his or her own legal advisor.

       Because an executed proxy relating to Heritage Common Stock on which no
  voting direction is made will be voted at the Special Meeting in favor of the
  Merger Agreement, a dissenting stockholder who wishes to have his or her
  shares of Heritage Common Stock represented by proxy at the Special Meeting
  but preserve dissenters' rights must, in addition to the foregoing
  requirements, mark the proxy card either to vote against the Merger Agreement
  or to abstain from voting thereon.

       The foregoing, while a summary of all material provisions of Part B of
  Division XIII of the IBCA, is qualified in its entirety by reference to the
  text of such statutory provisions, which is set forth in Annex C herein.

  Voting Agreements

       As a condition to Commercial entering into the Merger Agreement, the 16
  directors and executive officers of Heritage have entered into Voting
  Agreements with Commercial.  Each Voting Agreement provides that the
  respective director or officer will vote all of his or her shares of Heritage
  Common Stock beneficially owned in favor of the Merger Agreement and the
  Acquisition Merger and prohibits such individual from voting his or her shares
  in favor of any (i) issuance of stock to any party other than Commercial or
  its affiliates or (ii) acquisition of stock or all or substantially all of the
  assets of Heritage by any party other than Commercial and its affiliates, or
  from exercising dissenters' rights under the IBCA.  Each Voting Agreement
  prohibits the sale, assignment, pledge or transfer of shares subject to the
  Voting Agreement to a third party unless, as a condition to such transfer,
  such third party executes a voting agreement in the form acceptable to
  Commercial.  Each Voting Agreement provides that it will terminate upon the
  earlier of (i) the Acquisition Merger Effective Time, and (ii) the termination
  of the Merger Agreement.
      
       The total number of shares of Heritage Common Stock subject to the Voting
  Agreements is 56,064, or 31.0% of the total shares outstanding as of the
  Record Date and entitled to vote at the Special Meeting.

   The Bank Merger

       Following the Acquisition Merger, Hawkeye 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 Bank Plan of Merger between
  Hawkeye and the Bank dated May 16, 1996.  At the Bank Merger Effective Time,
  the shares of Hawkeye Common Stock issued and outstanding immediately prior
  thereto will be cancelled and the shares of the capital stock of the Bank
  outstanding immediately prior thereto will constitute the only outstanding
  shares of the 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 Hawkeye and all branch
  offices of the Bank and former branch offices of Hawkeye will be branch
  offices of the Bank.  Following the Bank Merger, the Bank will continue to
  operate under the name "Commercial Federal Bank, a Federal Savings Bank."  For
  additional information, see " -- Management after the Merger," " -- Employee
  Benefits 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 and the Bank will not be
  affected by the Merger.

  Representations and Warranties

       Commercial and the Bank, and Heritage and Hawkeye, have given certain
  representations and warranties to each other in the Merger Agreement relating
  to, among other things, the following: the validity of their respective
  organizations; capitalization; ownership of their subsidiaries; financial

  Covenants Pending the Acquisition Merger

       In the Merger Agreement, Commercial, the Bank, Heritage and Hawkeye 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 its
  respective representatives and agents full access (to the extent lawful) to
  all of the premises, books, records and employees of it and its subsidiaries
  at all reasonable times, and to furnish and cause its subsidiaries to furnish
  to the other party and its respective agents or representatives access to and

       Pursuant to the Merger Agreement, Heritage has agreed that it and its
  subsidiaries, including Hawkeye, will conduct their business only in the
  ordinary course, and maintain their books and records in accordance with past
  practices.  Further, Heritage has agreed that it will not, without the prior
  written consent of Commercial: (i) declare, set aside or pay any dividend or
  make any other distribution with respect to Heritage's capital stock,
  including, but not limited to, any distribution related to the Bennett Funding
  Asset not otherwise contemplated by the Merger

                                       31
<PAGE>
 
  Agreement, except for the regular quarterly dividends on the Heritage Common
  Stock in an amount not to exceed $1.00 per share, per quarter to the extent
  that, with respect to each such quarterly dividend, (A) the dividend does not
  exceed Heritage's net income (as determined in accordance with generally
  accepted accounting principles ("GAAP") exclusive of the effects of the
  following two items: (1) the charge-off or reserve on the Bennett Funding
  Asset taken by Heritage and (2) any additional provisions for loan and real
  estate owned losses established by Heritage and Hawkeye pursuant to the Merger
  Agreement for the quarter for which the respective dividend is paid; and (B)
  such dividends are paid on or about the dates customarily fixed by Heritage
  for the payment of dividends; (ii) reacquire any of Heritage's outstanding
  shares; (iii) issue, sell or buy any shares of capital stock of Heritage or
  any of its subsidiaries, except for shares of Heritage Common Stock issued
  under the Heritage Option Plan; (iv) effect any stock split, stock dividend or
  other reclassification of Heritage Common Stock; or (v) grant any options or
  issue any warrants exercisable for, or securities convertible or exchangeable
  into, capital stock of Heritage or any Heritage subsidiary or grant any stock
  appreciation or other rights with respect to shares of capital stock of
  Heritage or any of its subsidiaries.

       In addition, except as otherwise permitted by the Merger Agreement,
  Heritage and its subsidiaries shall not, without the prior written consent of
  Commercial:

       (i)     sell or dispose of any significant assets of Heritage or any of
  its subsidiaries other than in the ordinary course of business consistent with
  past practices;

       (ii)    merge or consolidate Heritage or any of its subsidiaries with, or
  otherwise acquire any other entity, or file any application or make any
  contract with respect to branching by Hawkeye (whether de novo, purchase, sale
  or relocation) or acquire or construct, or enter into any agreement to acquire
  or construct, any interest in real property (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;

       (iii)   change the articles of incorporation, charter documents or other
  governing instruments of Heritage or any of its subsidiaries, except as
  required by law or regulation;

  previously disclosed to Commercial, or (b) any bonus type payment, except as
  previously disclosed to Commercial;

       (v)     adopt any new or amend or terminate any existing employee plans
  or benefit arrangements of any type, or amend the terms of any outstanding
  awards under existing employee benefit plans;

       (vi)    authorize severance pay or other benefits for any officer,
  director or employee of Heritage or any of its subsidiaries, other than as
  previously disclosed to Commercial;

       (vii)   incur any material indebtedness or obligation or enter into or
  extend any material agreement or lease, except in the ordinary course of
  business consistent with past practices;

       (viii)  engage in any lending activities other than in the ordinary
  course of business consistent with past practices;

       (ix)    form any new subsidiary or cause or permit a material change in
  the activities presently conducted by any Heritage subsidiary or make
  additional investments in subsidiaries;

       (x)     purchase any debt securities or derivative securities, including

  as revised, or purchase any derivatives contracts or structured notes;

       (xi)    purchase any equity securities other than Federal Home Loan Bank
  ("FHLB") stock;

                                       32
<PAGE>
 
       (xii)   make any investment which would cause Hawkeye to not be a
  qualified thrift lender under Section 10(m) of the Home Owners' Loan Act or
  not to be a "domestic building and loan association" as defined in Section
  7701(a)(19) of the Code;

       (xiii)  make any loan with a principal balance of $250,000 or more;

       (xiv)   authorize capital expenditures other than in the ordinary course

  practices or methods other than as may be required by GAAP, or adopt or
  implement any change in its methods of accounting for federal income tax
  purposes;

       (xvi)   make any loan in which participation interests therein are to be
  sold to other persons or entities or acquire a participation interest in a
  loan originated by another person or entity; or

       (xvii)  commit to do any of the above.

  Notwithstanding the foregoing, Hawkeye is permitted to engage in any of the
  foregoing activities exclusively with the Bank.

       Heritage has further undertaken (i) to call the Special Meeting for the
  purpose of voting upon the Acquisition Merger and related matters, as soon as
  practicable, but in no event later than 60 days after the Registration
  Statement becomes effective; (ii) to recommend approval of the Acquisition
  Merger, except as the fiduciary duties of its Board of Directors otherwise
  requires; (iii) to use its best efforts to solicit from its stockholders
  proxies in favor of the approval of the Acquisition Merger and the Merger
  Agreement and to take all actions necessary to secure a vote of the holders of
  the Heritage Common Stock in favor of the transaction, except as the fiduciary
  duties of its Board of Directors may require; (iii) with Hawkeye, to use their
  respective best efforts to obtain the consent or approval of each person whose
  consent or approval is required in order to consummate the Acquisition Merger
  and the Bank Merger; (iv) to refrain from taking any action that would
  materially impede or delay consummation of the transactions contemplated by
  the Merger Agreement or that would prevent the transactions from qualifying as
  a reorganization within the meaning of Section 368 of the Code; (v) to refrain
  from making any press release, disclosure or statement to the press or any
  third party with respect to the transactions contemplated by the Merger
  Agreement, except as required by law, without the prior approval of
  Commercial; (vi) to furnish to Commercial, as soon as reasonably practicable
  after they become publicly available, its statements of financial condition
  and related statements of operations for all periods prior to the closing of
  the Acquisition Merger, such statements to be prepared in accordance with GAAP
  applied on a consistent basis and present fairly the financial condition and
  results of operations of Heritage (subject, in the case of unaudited financial
  statements to (A) normal year-end audit adjustments, (B) any other adjustments
  described therein, and (C) the absence of notes which, if presented, would not
  differ materially from those included in its most recent audited consolidated
  balance sheet); (vii) prior to the Acquisition Merger Effective Time, with
  Hawkeye, to establish such additional provisions for loan and real estate
  owned losses as may be necessary in the sole determination of Commercial to
  conform Heritage's and Hawkeye's loan and real estate owned allowance
  practices and methods to those of Commercial and the Bank; provided, however,
  that Heritage and Hawkeye will not be required to take such action until (A)
  Heritage and Hawkeye provide to Commercial a written statement dated the date
  of the closing of the Acquisition Merger regarding the satisfaction of certain
  covenants or alternatively setting forth the circumstances that have prevented
  such conditions from being satisfied, and (B) Commercial and the Bank, after
  reviewing such certificate, provides to Heritage and Hawkeye a written waiver
  of any right they may have to terminate the Merger Agreement; and (viii) until
  the Acquisition Merger Effective Time, to promptly, but not less frequently
  than monthly, update the disclosure schedule provided to Commercial in
  connection with the execution of the Merger Agreement, to reflect any matters
  which have occurred from and after the date of the Merger Agreement which, if
  existing on the date of the Merger Agreement, would have been required to be
  described therein and which, in the case of all such updates other than the
  last such update prior to the Acquisition Merger Effective Time, reflect a
  material change from the information provided in the disclosure schedule.

  No Solicitation

       The Merger Agreement provides that Heritage will not authorize or permit
  any representative of Heritage or any subsidiary to initiate contact with any
  person or entity in an effort to solicit, initiate or encourage any "takeover
  proposal" (generally, any bona fide proposal other than as contemplated by the
  Merger Agreement, for a merger or other business combination involving
  Heritage or Hawkeye, for the acquisition of a 10.0% or greater equity interest
  in Heritage or Hawkeye or for the acquisition of a substantial portion of the
  assets of Heritage or Hawkeye). In addition, except as the fiduciary duties of
  Heritage's Board of Directors may otherwise require (as determined in
  consultation with legal counsel), Heritage may not (or authorize any
  representative to): (i) cooperate with, or furnish, or cause to be furnished,
  any non-public information concerning Heritage's business, properties or
  assets to any person or entity in connection with any takeover proposal; 
  (ii) negotiate any takeover proposal with any person or entity; or (iii) enter
  into any agreement, letter of intent or agreement in principle as to any
  takeover proposal. Further, Heritage has agreed to give prompt written notice
  to Commercial upon becoming aware of any takeover proposal, such notice to
  contain, at a minimum (except as the fiduciary duties of Heritage's Board of
  Directors may otherwise require), the identity of the persons submitting the
  takeover proposal, a copy of any written inquiry or other communication, the
  terms of the takeover proposal, any information requested or discussions
  sought to be initiated and the status of any requests, negotiations or
  expressions of interest.

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

       The Merger Agreement may be terminated at any time before the Acquisition
  Merger Effective Time, whether before or after approval by Heritage
  stockholders: (i) by mutual written consent of the parties; (ii) at the
  election of either party, if the closing of the Merger shall not have occurred
  on or before January 31, 1997 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 Heritage if any event occurs which renders
  impossible the satisfaction in any material respect of one or more of the
  conditions to the obligations of Commercial and the Bank to effect the Merger
  as set forth in the Merger Agreement and noncompliance is not waived by
  Commercial; (iv) by Heritage upon delivery of written notice of termination to
  Commercial if any event occurs which renders impossible the satisfaction in
  any material respect of one or more of the conditions to the obligations of
  Heritage to effect the Merger set forth in the Merger Agreement and
  noncompliance is not waived by Heritage; (v) by Heritage at any time during
  the two business days commencing on the business day immediately following the
  end of the Determination Period, if the Average NYSE Closing Price of
  Commercial Common Stock is less than $33.50, as adjusted for any stock split,
  stock dividend, reclassification, combination of shares or similar corporate
  rearrangement; provided, however, that Heritage shall not be entitled to
  terminate the Merger Agreement on this basis if Commercial exercises its
  option to adjust the Merger Consideration so that the aggregate per share
  value of the Merger Consideration Merger Consideration consists of cash in the
  amount of $18.73 (subject to increase in the event of the sale or recovery of
  the Bennett Funding Asset) and that number of shares of Commercial Common
  Stock arrived at by dividing 91.08 by the Average NYSE Closing Price; and (vi)
  by Heritage if in the exercise of its good faith and reasonable judgment as to
  fiduciary duties to its stockholders imposed by law, as advised by special
  counsel, the Board of Directors of Heritage determines that such termination
  is required in connection with entering into an agreement with a third party
  to engage in an "Acquisition Transaction" (as such term is defined below),
  provided that Heritage must notify Commercial promptly of its intention to
  terminate the Merger Agreement and Heritage's ability to terminate the Merger
  Agreement is conditioned upon its prior payment of the $1.0 million
  termination fee required by the Merger Agreement.

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

  Termination Fee

       The Merger Agreement further provides that in the event the Merger
  Agreement is terminated by either Commercial or Heritage in accordance with
  the Merger Agreement (other than if terminated by Heritage as a result of
  Commercial's or the Bank's noncompliance with the conditions set forth in
  Section 5.3(b) of the Merger Agreement) and, prior to such termination a
  "Termination Event" (as defined below) has occurred, Heritage or Hawkeye shall
  be obligated to pay to Commercial or the Bank, upon demand, a termination fee
  of $1.0 million.  A "Termination Event" is defined in the Merger Agreement to
  mean either of the following:  (i) Heritage, or any

                                       36
<PAGE>
 
  subsidiary having entered into an agreement to engage in an "Acquisition
  Transaction" (as defined below) with any person or group other than Commercial
  or an affiliate of Commercial, or the Board of Directors of Heritage having
  recommended that the stockholders of Heritage approve or accept any
  "Acquisition Transaction" (as defined below) with any party other than
  Commercial or an affiliate of Commercial; or (ii) after a bona fide proposal
  is made by any party other than Commercial or an affiliate of Commercial to
  Heritage or its stockholders to engage in an "Acquisition Transaction", either
  (A) Heritage breaches any covenant or obligation contained in the Merger
  Agreement and such breach would entitle Commercial to terminate the Merger
  Agreement or (B) the holders of Heritage Common Stock do not approve the
  Merger Agreement at the Special Meeting, such meeting is not held or is
  cancelled prior to the termination of the Merger Agreement, or Heritage's
  Board of Directors withdraws or modifies in a manner adverse to Commercial its
  recommendation with respect to the Merger Agreement.

       For purposes of the Merger Agreement, the term "Acquisition Transaction"
  is defined to mean:  (i) a merger or consolidation or any similar transaction
  involving Heritage or any subsidiary of Heritage; (ii) a purchase, lease or
  other acquisition of all or substantially all of the assets of Heritage or any
  Heritage subsidiary; or (iii) a purchase or other acquisition (including by
  way of merger, consolidation, share exchange or otherwise) of securities
  representing 50% or more of the equity securities of Heritage or any Heritage
  subsidiary.

  Required Regulatory Approvals

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

  Expenses

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

  Closing; Merger Effective Times

       As promptly as practicable but in any event no more than 30 days after
  the satisfaction or waiver of all conditions and/or obligations of the parties
  contained in the Merger Agreement, a closing shall take place at which the
  parties thereto will exchange documents required by the Merger Agreement.  The
  Acquisition Merger Effective Time will be at the time and date which is the
  later of the time at which (i) the Nebraska articles of merger are filed with
  the appropriate authorities in Nebraska and (ii) the Iowa articles of merger
  are filed with the appropriate authorities of Iowa.  Following the Acquisition
  Merger, the Bank Merger Effective Time shall be at the time the articles of
  combination for such merger are endorsed by the OTS.

  Employee Benefits after the Merger

       Not later than 30 days following the Acquisition Merger Effective Time,
  the employees of Heritage and Hawkeye who become employees of Commercial
  and/or the Bank shall be eligible to participate in all benefit plans
  sponsored by Commercial or the Bank to the same extent as other similarly
  situated employees of Commercial and

                                       37
<PAGE>
 
  the Bank; provided, however, that comparable Heritage and Hawkeye benefit
  plans will be maintained until such time as such employees commence
  participation in the Commercial benefit plans. Commercial shall honor accrued
  vacation leave for the employees of Heritage and Hawkeye, with full credit for
  prior service with Heritage or Hawkeye for purposes of vesting and eligibility
  for participation and co-payments and deductibles.  With respect to employees
  of Heritage or Hawkeye who are covered by the Commercial health plan following
  the Acquisition Merger Effective Time, there shall be no exclusion from
  coverage for pre-existing conditions that were covered under any health
  insurance plan of Heritage or Hawkeye.

       Severance Benefits.  Employees of Hawkeye who are not offered a similar
  position with the Bank upon consummation of the Merger, or who have worked for
  the Bank through an assigned transition period and are not offered similar
  employment with the Bank, will receive severance benefits of one week's salary
  per credited year of service with Hawkeye, up to a maximum of sixteen weeks
  salary.

  Interests of Certain Persons in the Merger

       Heritage Stock Options.  The following table sets forth as of the Record
  Date information regarding outstanding options under the Heritage Option Plan
  held by directors and executive officers of Heritage.  Immediately prior to
  the Acquisition Merger Effective Time, each holder of an option outstanding
  under the Heritage Option Plan, whether or not the option is then exercisable,
  will receive in cancellation of such option (per share of Heritage Common
  Stock subject to such option) a cash payment in an amount equal to the per
  share value of the Merger Consolidation, less the exercise price of such
  option, net of any cash which must be withheld under federal and state tax
  requirements.

       Employment and Severance Agreements.  Three executive officers of
  Hawkeye, Messrs. John F. Peterson, R.T. Schreck and R. Michael Riddle, are
  parties to employment agreements with Heritage and Hawkeye that provide for
  severance payments and continuation of other employee benefits upon the
  occurrence of certain events, including termination of their respective
  employment under such agreements following a change in control of Heritage or
  Hawkeye. It is currently anticipated that, as a result of the Merger, the
  three executive officers will become entitled to severance payments under
  their current employment agreements in the approximate amounts of $324,000,
  $185,000 and $154,000, respectively.

       In addition to the foregoing, four other officers of Hawkeye, Messrs. Jon
  Aldrich, Robert E. Runyan, Randy P. Schmitz and Ms. Vicki Berg, are parties to
  agreements with Heritage and Hawkeye which provide for severance payments and
  continuation of other employee benefits for 12 months upon their involuntary
  termination of employment following a change of control of Heritage or
  Hawkeye.  It is currently anticipated that, as a result of the Merger, Messrs.
  Aldrich, Runyan, Schmitz and Ms. Berg will be entitled to severance payments
  in the approximate amounts of $49,000, $77,000, $59,000 and $44,000,
  respectively.

       The payments and benefits to be provided to the above-mentioned executive
  and other officers of Hawkeye pursuant to their individual employment or other
  agreements will be limited to an amount that would not cause the aggregate
  value of such payments and benefits to be treated as an "excess parachute
  payment" within the meaning of Section 280G of the Code.  Section 280G
  provides that severance payments or benefits which equal or exceed three times
  the "base amount" (as defined in Section 280G) of compensation of the
  individual are deemed to be "excess parachute payments" if they are contingent
  upon a change in control.

       Indemnification of Heritage Management.  Pursuant to the Merger
  Agreement, Commercial has agreed to indemnify the employees, agents, directors
  and officers of Heritage and its subsidiaries to the same extent they are
  indemnified under Heritage's Articles of Incorporation or Bylaws in effect at
  the date of the Merger Agreement or arising by operation of law.  Commercial
  has further agreed to cause the persons serving as officers and directors of
  Heritage immediately prior to the Acquisition Merger Effective Time to be
  covered for the duration of any applicable statute of limitation by individual
  directors' and officers' liability insurance 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.  The
  amount of the coverage obtained for each director and officer will be the
  amount available under the terms of such individual policies when $3,500 is
  expended per person.  In no event will Commercial be required to expend in the
  aggregate in excess of $55,000 to obtain such coverage.

  Federal Income Tax Consequences

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

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

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

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

                                       39
<PAGE>
 
       .     no gain or loss should be recognized by Commercial on the receipt
             of Heritage's assets in exchange for Commercial Common Stock, and
             the assumption by Commercial of Heritage's liabilities, by reason
             of the application of Section 1032(a) of the Code.

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

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

       .     the gain, if any, to be realized by a Heritage stockholder who
             receives Commercial Common Stock (including fractional share
             interests a Heritage stockholder would otherwise be entitled to
             receive) and cash (including amounts, if any, to be received
             relating to the Bennett Funding Asset) in exchange for Heritage
             Common Stock should be recognized, but not in excess of the amount
             of cash received. If the exchange has the effect of the
             distribution of a dividend (determined with application of Section
             318(a) of the Code), then the amount of gain recognized that is not
             in excess of each stockholder's ratable share of undistributed
             earnings and profits will be treated as a dividend. The
             determination of whether the exchange has the effect of the
             distribution of a dividend will be made on a stockholder-by-
             stockholder basis. No loss will be recognized on the exchange.

       .     the basis of the Commercial Common Stock (including fractional
             share interests a Heritage stockholder would otherwise be entitled
             to receive) to be received by a Heritage stockholder who exchanges
             Heritage Common Stock for Commercial Common Stock and cash will be
             the same as the basis of the Heritage Common Stock surrendered in
             the Merger, decreased by the amount of cash received, and increased
             by the amount that is treated as a dividend (if any), and by the
             amount of gain recognized on the exchange (not including any
             portion of that gain that was treated as a dividend).

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

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

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

       .     cash received by a stockholder of Heritage otherwise entitled to
             receive a fractional share of Commercial Common Stock in exchange
             for his Heritage Common Stock should be treated as if the
             fractional shares were distributed as part of the Merger and then
             were redeemed by Commercial.  These cash payments should be treated
             as having been received as distributions in full payment in
             exchange for the stock redeemed as provided in Section 302(a) of
             the Code.  This

                                       40
<PAGE>
 
             receipt of cash should result in gain or loss measured by the
             difference between the basis of such fractional share interest and
             the cash received.  Such gain or loss should be a capital gain or
             loss to the former Heritage stockholder, provided that the Heritage
             Common Stock was a capital asset in such former stockholder's hands
             and as such, will be subject to the provisions and limitations of
             Subchapter P of Chapter 1 of the Code.

       .     when cash is received by a dissenting stockholder of Heritage, such
             cash will be treated as received by the dissenting stockholder as a
             distribution in redemption of the stockholder's Heritage Common
             Stock, subject to the provisions and limitations of Section 302 of
             the Code.

    
  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 the Registration Statement of which this
  Prospectus/Proxy Statement is a part.  See " -- Available Information."      

       Cash payments made to the holders of Heritage 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 HERITAGE STOCKHOLDER'S SITUATION.  EACH
  HERITAGE STOCKHOLDER IS ENCOURAGED TO CONSULT HIS OR HER OWN TAX AND FINANCIAL
  ADVISORS AS TO PARTICULAR FACTS AND CIRCUMSTANCES THAT MAY BE UNIQUE TO SUCH
  STOCKHOLDER AND NOT COMMON TO STOCKHOLDERS AS A GROUP AND ALSO AS TO ANY
  ESTATE, GIFT, STATE, LOCAL OR FOREIGN TAX CONSEQUENCES ARISING OUT OF THE
  MERGER AND/OR ANY SALE THEREAFTER OF COMMERCIAL COMMON STOCK RECEIVED IN THE
  MERGER.

  Accounting Treatment
    
       The Merger will be accounted for under the purchase method of accounting
  in accordance with GAAP, resulting in adjustments to Heritage's assets and
  liabilities to reflect their respective fair values at the date of the
  Acquisition Merger.      

  Resale of Commercial Common Stock; Restrictions on Transfer

       The shares of Commercial Common Stock to be issued in the Acquisition
  Merger will be registered under the Securities Act and will be freely
  transferable under the Securities Act, except for shares issued to any
  stockholder who may be deemed to be an "affiliate" of Heritage 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
  Heritage 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.

  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 Heritage
  Common Stock is required for Heritage's stockholders to approve the Merger
  Agreement and the Acquisition Merger.  Each share of Heritage Common Stock
  outstanding at the close of business on the Record Date is entitled to one
  vote on each matter to be considered at such meeting.  Heritage's directors
  and executive officers have executed Voting Agreements which require such
  individuals to vote substantially all of the 56,064 shares of Heritage Common
  Stock (excluding stock options), beneficially owned by them as of the Record
  Date for approval of the Acquisition Merger and the Merger Agreement.      

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

       Commercial is a unitary non-diversified savings and loan holding company
  whose primary asset is the Bank, the largest depository institution
  headquartered in Nebraska. At March 31, 1996, Commercial has assets of $6.6
  billion and stockholders' equity of $400.4 million.  Based upon total assets
  at that date, Commercial was the 18th largest publicly held thrift holding
  company in the United States.  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.  At March 31, 1996, the Bank operated 38 branch offices in
  Nebraska, 20 branch offices in greater metropolitan Denver, Colorado, 18
  branch offices in Oklahoma, 24 branch offices in Kansas and one branch office
  in Iowa.  Subsequent to March 31, 1996, the Bank consolidated four branches in
  Nebraska due to market overlap resulting from the acquisition of Conservative
  and opened an additional branch in Oklahoma.  Accordingly, at June 30, 1996,
  the Bank operated a 98 branch network.  Throughout its 109 year history, the
  Bank has emphasized customer service.  To serve its customers, the Bank
  conducts loan origination activities through its branch office network, loan
  offices of its wholly-owned mortgage banking subsidiary and a nationwide
  correspondent network consisting of approximately 400 mortgage loan
  originators.  The Bank also provides insurance and securities brokerage and
  other retail financial services.

       On October 2, 1995, Commercial completed the acquisition of Railroad
  headquartered in Wichita, Kansas, the holding company for Railroad Savings
  Bank, FSB.  Railroad operated 18 full-service branch offices and 71 agency
  offices throughout the State of Kansas and at acquisition date had $602.9
  million in total assets, $421.4 million in deposits and $27.7 million in
  stockholders' equity.  On February 1, 1996, Commercial completed the
  acquisition of Conservative, headquartered in Omaha, Nebraska, the holding
  company for Conservative Savings Bank, FSB.  Conservative operated seven
  offices in Nebraska, one office in Iowa and one office in Kansas and at
  February 1, 1996, had $302.9 million in total assets, $197.9 million in
  deposits and $35.1 million in stockholders' equity.

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

       Complementing its strategy of internal growth, Commercial will continue
  to grow its five-state franchise through an ongoing program of selective
  acquisitions of other financial institutions.  Acquisition candidates will be

                                       42
<PAGE>
 
  selected based on the extent to which the candidates can enhance Commercial's
  retail presence in new or underserved markets and complement Commercial's
  existing retail network.

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

                            HERITAGE FINANCIAL, LTD.
                                        
       Heritage is a savings and loan holding company for Hawkeye.   Heritage
  became the holding company for Hawkeye effective February 23, 1990.
  Accordingly, the information set forth in this Prospectus/Proxy Statement,
  including financial statements and related data, relates primarily to Hawkeye
  and its subsidiaries.

       Hawkeye was originally chartered by the State of Iowa in 1926 as a mutual
  savings and loan association.  In 1984, Hawkeye converted from a mutual
  savings and loan association to a capital stock savings and loan association
  through the sale and issuance of 152,090 shares of capital stock at $8.00 per
  share.  In January 1985, Hawkeye converted from an Iowa chartered stock
  savings and loan association to a federally chartered stock savings bank.  In
  1992, Heritage acquired First Federal in a voluntary supervisory conversion.
  First Federal was merged with Hawkeye in March 1995.

       Hawkeye's primary business is the solicitation of savings deposits from
  the general public and the origination of loans secured by residential real
  estate.  Hawkeye participates in the secondary mortgage market through the
  purchase of mortgage-backed securities and through correspondent relationships
  which involve the origination of residential real estate loans.  It also
  invests funds in securities approved for investment by federal regulations,
  including obligations of the United States and its agencies.  Hawkeye
  continues to expand its operations to include consumer and commercial lending,
  demand and commercial checking, and money market deposit accounts.  Hawkeye's
  income is derived largely from interest and fees in connection with lending
  activities.  Its principal expenses are interest paid on savings deposits and
  operating expenses.
    
       Hawkeye is a member of the FHLB System and its deposits are insured by
  the FDIC under the SAIF.  Hawkeye is subject to extensive federal regulation,
  see "Regulation -- Federal Regulation of Hawkeye."      

       For additional information, see the Consolidated Financial Statements of
  Heritage included in pages F-1 through F-34 herein.

                      BUSINESS OF HERITAGE FINANCIAL, LTD.
 
  Lending Activities

       General. Hawkeye's principal lending activity is the origination of
  conventional mortgage loans (loans that are neither insured nor partially
  guaranteed by government agencies), including construction loans secured by
  residential real estate located in its primary market areas. See 
  " -- Competition" for a description of Hawkeye's primary market areas. 
  Hawkeye also originates consumer loans, home equity loans and loans secured 
  by savings deposits.

       Residential Real Estate Loans.  Hawkeye grants loans secured by single-
  family residential real estate to enable borrowers to purchase existing homes
  or to construct new single family homes.  Hawkeye's real estate loan portfolio
  also includes loans secured by two-to-four family dwellings.  Hawkeye offers
  fixed-rate and adjustable-rate mortgage ("ARM") loans.

       At March 31, 1996, approximately $83.5 million, or 56.0% of total loans
  outstanding (including mortgage-backed securities and certain construction
  loans), consisted of loans and mortgage-backed securities secured by one-to-
  four family residential real estate.  At March 31, 1996, one-to-four family
  ARM loans represent 55% of the mortgage portfolio.

       The average remaining contractual maturity of Hawkeye's mortgage loan
  portfolio is approximately 16 years and Hawkeye is currently originating loans
  with maturities of 15, 20, 25 and 30 years.  Hawkeye's experience, however,
  indicates that residential loans remain outstanding for significantly shorter
  periods than their contractual terms.  Borrowers may refinance or prepay loans
  at their option.

       Hawkeye's lending policies generally limit the maximum loan-to-value
  ratio on fixed-rate and ARM loans, without private mortgage insurance, to
  either 80% or less of the lesser of the appraised value or purchase price of
  the underlying residential property or up to 95% with private mortgage
  insurance.  The loan-to-value ratio, maturity and other provisions of the
  loans made by Hawkeye have generally reflected the policy of making loans at
  less than the maximum loan-to-value ratio permissible under federal
  regulations, in accordance with established lending practices, market
  conditions and underwriting standards maintained by Hawkeye.

       Hawkeye has also engaged in construction lending.  These loans involve a
  construction period requiring monthly interest payments, followed by a
  permanent loan requiring monthly principal and interest payments.  At 
  March 31, 1996, Hawkeye's construction loan portfolio totaled $1.7 million.

       Commercial Real Estate Loans.  At March 31, 1996, Hawkeye had
  approximately $8.9 million of commercial real estate loans, including loans
  secured by apartments with more than four units and commercial construction
  loans.  This represents 6% of its outstanding loan portfolio (before
  deductions).  In recent years, commercial lending as a percentage of the loan
  portfolio has been decreasing.  All new loans are made on an adjustable-rate
  basis, with loan terms ranging up to a maximum of 20 years.

       Although commercial real estate loans typically have shorter terms to
  maturity and higher interest rates than residential mortgage loans, they also
  may involve greater credit risk than residential mortgage loans.  Such loans
  may involve large loan balances to single borrowers or groups of related
  borrowers.  In addition, payment experience on loans secured by income
  producing properties is typically dependent on the successful operation of the
  properties and thus may be subject to a greater extent to adverse conditions
  in the real estate market or in the economy generally.  At March 31, 1996,
  Hawkeye's largest commercial real estate loan totaled $1.5 million.  Hawkeye's
  largest commercial real estate loan is secured by a multi-family apartment
  complex located in Sergeant Bluff, Iowa and was performing according to its
  terms at March 31, 1996.

       Consumer and Other Loans.  At March 31, 1996, Hawkeye had $51.6 million
  in home improvement and other consumer loans.  Federal regulations permit
  federal thrift institutions to make secured and unsecured consumer loans up to
  35% of the institution's assets.  In addition, a federal thrift institution
  has lending authority above this percentage for certain consumer loans, such
  as home equity loans, property improvement loans and loans secured by savings
  accounts.  Loans are made to purchase, maintain, repair, improve, landscape or
  equip the secured property, including additions to or new construction on
  existing property.  It has been Hawkeye's experience that these loans are made
  primarily on property secured by a first mortgage to Hawkeye.  Hawkeye
  generally makes these loans for terms of seven to 10 years, but the term may
  extend to 15 years.  Hawkeye makes unsecured and secured consumer loans on
  automobiles, boats, trailers and equipment at a typical loan to value ratio of
  75% for a typical term of 36 to 48 months.

                                       45

       Hawkeye also makes loans secured by savings deposits.  At March 31, 1996,
  Hawkeye had $327,000 in loans secured by savings deposits.

       In addition to commercial real estate loans, Hawkeye also makes
  commercial loans secured by other business assets.  At March 31, 1996, Hawkeye
  had $5.3 million in commercial loans secured other than by real estate.
  Included in this balance is the $1.8 million loan to Bennett.  This loan was
  non performing at March 31, 1996.  Subsequent to March 31, 1996, management
  subsequently determined to fully reserve for the entire balance of this loan.
  Such reserve had the effect of reducing fourth quarter earnings by $1.8
  million less the tax benefit of $600,000 for a net effect of $1.2 million.

  Funding Asset."

       Loan and Mortgage-Backed Securities Maturity and Repricing.  The
  following table sets forth certain information at June 30, 1995 regarding the
  dollar amount of loans and mortgage-backed securities maturing in Hawkeye's
  portfolio based on their contractual terms to maturity.  Demand loans, loans
  having no stated schedule of repayments and no stated maturity, and overdrafts
  are reported as due in one year or less.  Loan balances do not include
  undisbursed loan proceeds, unearned discounts, unearned income and allowance
  for loan losses.

       Loan Solicitation and Processing.  Hawkeye's primary sources of loans
  include referrals, brokers, contractors, repeat business from existing and
  former borrowers.

       Once an application for a mortgage loan is received by Hawkeye, a credit
  and property analysis is completed, including obtaining a credit report from
  reporting agencies, verification of income and deposits, and assets and
  liabilities.  An appraisal of the property offered as collateral is prepared
  by a fee appraiser approved by Hawkeye.

       The completed loan file is then submitted for underwriting.  Once
  underwritten, the loan is submitted to the appropriate committee for review
  and approval.  Single-family residential loans up to $250,000 may be approved
  by certain officers of Hawkeye.  Approval of the Board of Directors of Hawkeye
  is required for Hawkeye to make a loan in excess of $250,000.

       Similar procedures and guidelines apply to the processing of commercial
  and consumer loans.

       Mortgage-Backed Securities.  Hawkeye invests in mortgage-backed
  securities guaranteed by the Government National Mortgage Association
  ("GNMA"), Federal National Mortgage Association ("FNMA") and the Federal Home
  Loan Mortgage Corporation ("FHLMC") and CMOs issued by various entities
  including FNMA and FHLMC. Of Hawkeye's total mortgage-backed securities of
  $32.5 million, $20.8 million carried adjustable rates at March 31, 1996.
  Management considers mortgage-backed securities investments to be advantageous
  since they offer yields above those available for investments of comparable
  credit quality and duration and qualify as thrift investments under the
  Qualified Thrift Lender ("QTL") Test.  See "Regulation -- Qualified Thrift
  Lender Test."

       Loan Originations, Purchases and Sales.  Most of Hawkeye's loan portfolio
  consist of loans originated by Hawkeye.  However, Hawkeye also acquires dealer
  paper without recourse from market area auto dealers, purchases conventional
  loans secured by residential real estate from various mortgage brokers located
  within Iowa, purchases participations in commercial and multi-family
  residential loans from other lenders, purchases home equity loans on 1-4
  family residences originated by other lenders and purchases mortgage-backed
  securities.  For the years ended June 30, 1995, 1994 and 1993, Hawkeye
  purchased mortgage-backed securities in the amount of approximately $1.9
  million, $11.1 million and $10.4 million, respectively.

       Hawkeye periodically sells loans that it originates into the secondary
  market.  These sales, primarily to FNMA, are made without recourse to Hawkeye.
  The sale of loans in the secondary mortgage market reduces Hawkeye's risk of
  interest rates escalating while holding long-term, fixed-rate loans in periods
  when savings flows decline or funds are not otherwise available for lending
  purposes.  In connection with such sales, Hawkeye retains the servicing of the
  loans (i.e., collection of principal and interest payments), for which it
         ----                                                              
  generally receives a fee payable monthly of .25% or more per annum of the
  unpaid balance of each loan.  As of March 31, 1996, Hawkeye's servicing
  portfolio totaled $26.4 million.  The success of these efforts, however, is
  limited by Hawkeye's ability to acquire loans at yields which are competitive
  with other loans in the market area.

       Loan Commitments.  Hawkeye makes commitments to purchase loans and
  mortgage-backed securities and originate loans to borrowers within its market.
  These commitments are subject to the occurrence of certain events and are made
  under specified terms and conditions.  Hawkeye generally makes these
  commitments for a duration of up to 60 days.  At March 31, 1996, Hawkeye had
  outstanding loan origination commitments of approximately $1.5 million.

       Loan Origination and Other Fees.  In addition to interest earned on
  loans, Hawkeye received loan origination fees or "points" for originating
  loans.  Loan points are a percentage of the principal amount of the mortgage
  loan which are charged to the borrower for creation of the loan.  Hawkeye's
  loan origination fees are generally 1.0% on conventional residential
  mortgages.  Such loan origination fees, net of costs to originate, are
  deferred and amortized using an interest method over the contractual life of
  the loan.  Fees deferred are recognized immediately upon prepayment or sale of
  the related loan.  The total amount of deferred loan fees for Hawkeye at 
  March 31, 1996 was $184,000.

       Hawkeye also receive other fees and charges relating to existing loans,
  which may include prepayment penalties, late charges, and fees collected in
  connection with a change in borrower or other loan modifications. These fees
  and charges have not constituted a material source of income.

       Problem Assets and Asset Classification.  Loans are reviewed on a regular
  basis and are placed on a non-accrual status when, in the opinion of
  management of Hawkeye, the collection of additional interest is doubtful.
  Residential mortgage loans generally are placed on non-accrual status when
  either principal or interest is 90 days or more past due. Consumer loans
  generally are charged off or reserved when the loan becomes 90-120 days
  delinquent. Commercial business and real estate loans are generally placed on
  non-accrual status when the loan is 90 days or more past due. Interest accrued
  and unpaid at the time a loan is placed on non-accrual status is charged
  against interest income. Subsequent payments are either applied to the
  outstanding principal balance or recorded as interest income, depending on the
  assessment of the ultimate collectibility of the loan.

       Real estate acquired by Hawkeye as a result of foreclosure or by deed in
  lieu of foreclosure is classified as foreclosed real estate until such time as
  it is sold. When such property is acquired it is recorded at the lower of the
  unpaid principal balance of the related loan or its fair value, less estimated
  selling expenses.  Any write-down of the property is charged to the allowance
  for loan losses at the time of foreclosure with subsequent declines in value,
  if any, credited directly to foreclosed real estate.

       The following table sets forth information with respect to Hawkeye's non-
  performing assets for the periods indicated. During the periods shown, Hawkeye
  had no restructured loans within the meaning of Statement of Financial
  Accounting Standards No. 15, other than any loans foreclosed and reported as
  real estate owned.

       During the year ended June 30, 1995, no gross interest income would have
  been recorded on loans accounted for on a non-accrual basis if the loans had
  been current throughout the period. There was no interest on such loans
  included in income during the period.

       During the period of negotiations with Commercial in late March 1996,
  Hawkeye had $1.8 million in loans to Bennett or its subsidiaries and loans to
  Bennett or its subsidiaries secured by equipment leases.  Approximately 10,000
  investors and 200 financial institutions nationwide had similar investments or
  lending relationships with Bennett.  Bennett filed for Chapter 11 bankruptcy
  protection on March 29, 1996 after the principals of the company were charged
  with various criminal offenses relating to the leasing transactions.  Upon the
  filing of the Bennett bankruptcy case, the Bennett Funding Asset became non
  performing.  At March 31, 1996, Hawkeye had not established a specific loss
  reserve for the Bennett Funding Asset but rather, considered its non
  performing nature when evaluating the adequacy of the allowance for loan
  losses.  At June 30, 1996, the Bennett Funding Asset was fully reserved in the
  amount of $1.8 million.  See "Information Concerning the Special Meeting --
  Recent Events -- Bennett Funding Asset."

(1)    Hawkeye maintained a specific loan loss reserve which had not been
       included as part of the allowance for loan losses in the Consolidated
       Financial Statements or schedules herein, but rather was netted against
       loans receivable.  As of March 31, 1996, this specific loan loss reserve
       has been transferred to the allowance for loan losses.


       The following table sets forth the components of the allowance for loan
  losses by loan category for the periods indicated.  Management believes that
  the allowance can be allocated by category only on an approximate basis. The
  allocation of the allowance to each category is not necessarily indicative of
  further losses and does not restrict the use of the allowance to absorb losses
  in any category.

  Investment Activities

       Interest income from cash deposits and investment securities generally
  provide the second largest source of income for Hawkeye after interest
  payments on loans. At March 31, 1996, Hawkeye's interest-bearing deposits,
  cash, and investment securities portfolio of $32.8 consisted primarily of FHLB
  overnight and fixed-term deposits and U.S. Government and agency obligations.

       Hawkeye is required under federal regulations to maintain a minimum
  amount of liquid assets which may be invested in specified short-term
  securities and is also permitted to make certain other investments.  It has
  been Hawkeye's policy to maintain a liquidity portfolio well in excess of
  federal regulatory requirements, and at March 31, 1996, Hawkeye's liquidity of
  $37.9 million exceeded federal requirements by $30.0 million.  Investment
  decisions are made by authorized officers of Hawkeye under the supervision of
  Hawkeye's Board of Directors.

       The following table sets forth the carrying value of Hawkeye's investment
  portfolio at the dates indicated.

  Savings Activities and Other Sources of Funds

       Deposits are the major source of Hawkeye's funds for lending and other
  investment purposes. In addition to deposits, Hawkeye derives funds from loan
  principal repayments, interest payments and advances from the FHLB of Des
  Moines.  Loan repayments and interest payments are a relatively stable source
  of funds, while deposit inflows and outflows may be influenced by changes in
  general interest rates.  Borrowings may be used on a short-term basis to
  augment traditional sources of funds.  They also may be used on a longer term
  basis for general business purposes.  As of March 31, 1996, Hawkeye had
  borrowed $10.0 million from the FHLB of Des Moines with amounts and terms
  varying from $1.0 to $5.0 million and one to five years in maturity.  The
  funds were used to purchase second mortgage loans.

       Hawkeye offers a number of deposit accounts, including passbook savings
  accounts, NOW/checking, money market accounts and certificate accounts ranging
  in maturity from 14 days to five years or more.  Deposit account interest
  rates vary according to minimum balance requirements and maturity dates.  Such
  accounts are not subject to the maximum interest rates imposed by government
  regulation.  There may be a penalty imposed on all deposit accounts withdrawn
  prior to the end of any required fixed or minimum term.

       Deposits in Hawkeye at March 31, 1996 were represented by various types
  of savings programs described below.

       Substantially all of Hawkeye's depositors are residents of the State of
  Iowa.

       Borrowings.  Savings deposits are the primary source of funds for
  Hawkeye's lending and investment activities.  However, during periods when the
  supply of lendable funds cannot meet the demand for such loans, the FHLB
  System seeks to provide a portion of the funds necessary through loans
  (advances) to its members.  The FHLB of Des Moines has served as Hawkeye's
  primary borrowing source. Advances may be on a secured or unsecured basis,
  depending on a number of factors, including the purpose for which the funds
  are being borrowed and existing advances outstanding.

       As of March 31, 1996, Hawkeye had $10.0 million in advances outstanding
  with the FHLB of Des Moines.  The advances all carry fixed rates ranging from
  5.94% to 6.21% and mature at various dates beginning on July 5, 1996, and
  ending on July 7, 2000.

       Yields Earned and Rates Paid.   Hawkeye's earnings depend significantly
  upon the difference between the income it receives from its loan and
  investment portfolios and its cost of borrowings, consisting of the interest
  paid on deposit accounts and borrowings, if any.  The ratios for the nine
  months ended March 31, 1996 and 1995 are annualized.

       The following table sets forth for the periods and at the date indicated,
  the weighted average yields earned on Hawkeye's interest-earning assets, the
  weighted average interest rates paid on their interest-bearing liabilities,
  the interest rate spread and the net yield on interest-earning assets.

Service Corporations
 
       Hawkeye is permitted under OTS regulations to invest up to 2% of its
  assets in service corporations, with an additional investment of 1% of assets
  where such investment serves primarily inner-city and community development
  purposes.  Under such limitations, at March 31, 1996 Hawkeye was authorized to
  invest up to approximately $3.7 million and $5.5 million, respectively, in the
  stock of, or loans to, service corporations (based upon the 3% limitation).
  At March 31, 1996 Hawkeye's investment in stock in its service corporation was
  approximately $337,000 and there were no secured or unsecured loans to the
  service corporation.

       Hawkeye incorporated a wholly-owned service corporation, Mid Central
  Service Corporation ("Mid Central"), in August 1975.  Mid Central is
  headquartered at 715 Eighth Street, Boone, Iowa, in Hawkeye's main office
  building and provides Hawkeye with a subsidiary for expanding customer
  services.

  Competition

       Hawkeye faces strong competition in the attraction of savings deposits
  (its primary source of lendable funds) and in the origination of real estate
  loans.  The most direct competition for savings deposits has historically come
  from other thrift institutions and from commercial banks located in their
  primary market areas.  Particularly in times of high interest rates, however,
  Hawkeye faces additional significant competition for investors' funds from
  short-term money market securities and other corporate and government
  securities.  Competition for real estate loans comes principally from other
  thrift institutions, commercial banks, mortgage banking companies, insurance
  companies and other institutional lenders.

  Personnel

       At March 31, 1996 Hawkeye had 63 full-time employees and 10 part-time
  employees.  The employees are not represented by a collective bargaining
  agreement.  Hawkeye believes its employee relations are good.

  Legal Proceedings

       Although Heritage and Hawkeye are, from time to time, involved in various
  legal proceedings in the normal course of business, there are, with the
  exception noted below, no material legal proceedings to which Heritage or
  Hawkeye is a party or to which any of their properties are subject.  Hawkeye
  has filed a claim in connection with the bankruptcy proceedings involving
  Bennett with respect to Hawkeye's interest in the Bennett Funding Asset.  See
  "Information Concerning the Special Meeting -- Recent Events -- Bennett
  Funding Asset."



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

  General

       Management's Discussion and Analysis of Financial Condition and Results
  of Operations is intended to assist in understanding the financial condition
  and results of operations of Heritage.  The information contained in this
  section should be read in conjunction with the Consolidated Financial
  Statements of Heritage as of June 30, 1995 and 1994 and for the years ended
  June 30, 1995, 1994 and 1993 and the unaudited consolidated condensed
  financial statements as of March 31, 1996 and for the nine month periods ended
  March 31, 1996 and 1995 and the accompanying notes for such periods which are
  included elsewhere in this Prospectus/Proxy Statement.

  Average Balance Sheet

       The following table sets forth certain information relating to Hawkeye's
  average balance sheet and reflects the average yield on assets and average
  cost of liabilities for the periods indicated and the average yields earned
  and rates paid.  Such yields and costs are derived by dividing income or
  expense by the average balance of assets or liabilities, respectively, for the
  periods presented.  For purposes of these tables, average balances were
  computed on a monthly basis.

       The table also presents information for the periods indicated with
  respect to the difference between the weighted average yield earned on
  interest-earning assets and weighted average rate paid on interest-bearing
  liabilities, or "interest rate spread," which savings institutions have
  traditionally used as an indicator of profitability.  Another indicator of an
  institution's net interest income is its "net yield on interest-earning
  assets."  Net interest income is affected by the interest rate spread and by
  the relative amounts of interest-earning assets and interest-bearing
  liabilities.  When interest-earning assets approximate or exceed interest-
  bearing liabilities, any positive interest rate spread will generate net
  interest income.

  Comparison of Financial Condition as of March 31, 1996, June 30, 1995 and June
  30, 1994
      
       Total assets of Heritage increased by $7.7 million to $185.4 million at
  March 31, 1996 from $177.7 million at June 30, 1995, primarily due to an
  increase in loans receivable, offset by a decrease in investment securities
  and mortgage-backed securities.  Securities available for sale increased $4.1
  million during the nine month period ended March 31, 1996 to $19.6 million
  from $15.5 million at June 30, 1995 while securities held to maturity
  decreased by $6.0 million during the same nine month period to $4.1 million
  from $10.1 million at June 30, 1995.  The change in securities available for
  sale and securities held to maturity is primarily due to the transfer of $8.4
  million of securities from held to maturity to available for sale
  classification and the subsequent sale of certain securities available for
  sale.  During the year ended June 30, 1994, Heritage adopted the provisions of
  Statement of Financial Accounting Standards ("SFAS") No. 115, "Accounting for
  Certain Investments in Debt and Equity Securities."  SFAS No. 115 requires
  classification of debt and equity securities into three securities.  Debt
  securities classified as "held to maturity" are those securities which
  Heritage has the positive intent and ability to hold to maturity and are
  reported at amortized cost.  Debt and equity securities that are bought and
  held principally for the purpose of selling them in the near term must be
  reported at fair value, with unrealized gains and losses included in earnings.
  All other debt and equity securities must be considered available for sale and
  must be reported at fair value, with unrealized gains and losses excluded from
  earnings but reported as a separate component of stockholders' equity (net of
  tax effects). During 1995, Financial Accounting Standards Board("FASB")
  Special Report - "A Guide to Implementation of Statement No. 115 on Accounting
  for Certain Investments in Debt and Equity Securities" allowed a reassessment
  of the appropriateness of the classification of securities under certain
  circumstances. In connection therewith, in December 1995 Heritage reclassified
  held-to-maturity securities with an amortized cost of $8.4 million and a fair
  value of $8.3 million as available for sale in accordance with the guidance
  provided by the report. The reclassification was made at fair value and the
  difference between the amortized cost and fair value on the date of transfer
  was recognized as a decrease in stockholders' equity, net of the related
  deferred tax effect.. Mortgage-backed securities held to maturity decreased
  $4.1 million to $32.5 million at March 31, 1996 from $36.6 million at June 30,
  1995 due to normal principal paydowns. Loans receivable, net increased $15.1
  million to $114.6 million at March 31, 1996 from $99.5 million at June 30,
  1995 primarily due to the purchase of approximately $21 million of home equity
  loans with a yield of approximately 9.0%. Hawkeye purchased these loans due to
  their greater spread as compared to other investment opportunities. Deposits
  of Hawkeye increased $2.9 million to $160.1 million at March 31, 1996 from
  $157.1 million at June 30, 1995. The increase in deposits was due to an
  increase in demand and money market accounts and is considered to be a normal
  fluctuation. Borrowed funds increased $5.0 million during the nine month
  period to $10.0 million at March 31, 1996 from $5.0 million on June 30, 1995.
  These funds were borrowed from the FHLB of Des Moines and were used to acquire
  home equity loans. Total stockholders' equity increased to $14.0 million at
  March 31, 1996 from $13.7 million at June 30, 1995. The $392,000 increase was
  primarily due to the retention of net income recorded during the nine month
  period less cash dividends paid of $541,000 and a decrease in the unrealized
  gain on securities available for sale, net of taxes, totaling $324,000. The
  portfolio of available for sale securities is comprised primarily of
  investment securities carrying fixed interest rates. The fair value of these
  securities is subject to change in interest rates and fair value of these
  securities decreased due to an increase in interest rates since the previous
  report period.     
      
       Total assets of Heritage increased by $5.2 million to $177.7 million at
  June 30, 1995 from $172.5 million at June 30, 1994, primarily due to an
  increase in loans receivable, offset by a decrease in investment securities
  and mortgage-backed securities. Securities available for sale decreased by
  $2.9 million to $15.5 million at June 30, 1995 from $18.4 million at June 30,
  1994 from the sale of securities available for sale. Securities held to
  maturity increased $200,000 to $10.1 million at June 30, 1995 from $9.9
  million at June 30, 1994. Mortgage-backed securities decreased $3.7 million to
  $36.6 million from $40.2 million, due primarily to normal principal paydowns.
  Loans receivable, net increased $8.3 million to $99.5 million at June 30, 1995
  from $91.2 million at June 30, 1994. This increase is attributed to an
  increase of $5.0 million in automobile loans, primarily acquired dealer paper,
  and an increase in demand for home equity and second mortgage loans. The
  increase in dealer paper was accomplished by the Bank becoming more aggressive
  in its pricing structure with auto dealers. Deposits were virtually unchanged,
  decreasing $550,000 to $157.1 million at June 30, 1995 from $157.7 million at
  June 30, 1994. Borrowed funds increased $5.0 million to $5.0 million at June
  30, 1995 from none at June 30, 1994. These funds were borrowed from the FHLB
  of Des Moines in order to fund a purchase of home equity loans in July 1995.
  Total stockholders'

<PAGE>
 
  equity increased $700,000 to $13.7 million at June 30, 1995 from $13.0 million
  at June 30, 1994.  This change was primarily due to net earnings for fiscal
  year 1995, offset by dividends of $623,000 and an increase in the unrealized
  gain on securities available for sale, net of taxes, totaling $395,000.  These
  funds were used to increase liquidity in order to purchase higher yielding
  home equity loans in July 1995.  The portfolio of securities available for
  sale is comprised primarily of investment securities carrying fixed interest
  rates.  The fair value of these securities is subject to change in interest
  rates and the fair value of these securities increased due to a decrease in
  interest rates since the previous reporting period.

  Comparison of Operating Results for the Nine Months Ended March 31, 1996 and
  1995

       Interest Income.  Total interest income increased $1.7 million for the
       ---------------                                                       
  nine months ended March 31, 1996 to $10.6 million as compared to $8.9 million
  for the same nine month period a year earlier.  The increase was due primarily
  to the purchase of approximately $21 million in home equity loans yielding
  approximately 9.0%.  Such yield was in excess of what had been realized from
  other interest-earning alternatives.  The average balance of loans outstanding
  increased by $20.0 million and the average yield increased from 8.14% to 8.69%
  from March 31, 1995 to March 31, 1996.

       Interest Expense.  Interest on savings deposits increased by $607,000 to
       ----------------                                                        
  $5.5 million from $4.9 million for the nine month period ended March 31, 1996
  compared to the same period a year earlier.  The increase was primarily due to
  the increase in the average rate paid on deposit accounts increasing from
  4.28% for 1995 to 4.77% for 1996, due to a general increase in market interest
  rates.  Interest on borrowed funds increased by $458,000 to $464,000 from
  $6,000 for the nine month period ended March 31, 1996 compared to the same
  period a year earlier.  The increase was due to the increase in borrowed funds
  used to fund the purchase of home equity loans discussed above.

       Provision for Loans Losses.  No provision for loan losses was made during
       --------------------------                                               
  the nine month period ended March 31, 1996 as compared to a $40,000 provision
  for loan losses during the nine months ended March 31, 1995.  The decrease of
  $40,000 for the nine month period was due to management's decision that the
  allowance for loan losses was adequate and no provision was deemed necessary.
  The allowance is maintained at an amount that management believes will be
  adequate to absorb estimated losses on existing loans that may become
  uncollectible, based on evaluation of the collectibility of loans and prior
  loss experience.  This evaluation also takes into consideration such factors
  as changes in the nature and volume of the loan portfolio, overall portfolio
  quality, review of specific problem loans, and current economic conditions
  that may affect the borrower's ability to pay.  While management uses the best
  information available to make its evaluation, future adjustments to the
  allowance may be necessary if there are significant changes in economic
  conditions.  The level of non-performing assets increased from $46,000 at June
  30, 1995 to $2.0 million at March 31, 1996, primarily due to the Bennett
  Funding Asset of approximately $1.8 million being placed on nonaccrual status.
  In evaluating the March 31, 1996 allowance for loan losses, Bank management
  reviewed the Bank's files relating to this loan.  Based on this review, and
  the limited information available at that time, management did not believe
  that an adjustment to the allowance for loan losses was warranted.  As of June
  30, 1996, a specific reserve totaling $1.8 million was established for the
  Bennett Funding Asset.  See "Information Concerning the Special Meeting --
  Recent Events -- Bennett Funding Asset."

       Noninterest Income.  Total noninterest income increased $463,000 to
       ------------------                                                 
  $652,000 from $189,000 for the nine months ended March 31, 1996.  The increase
  was due primarily to a $244,000 gain on the sale of interest-earning assets,
  compared to a loss of $188,000 in the previous period.

       Noninterest Expense.  Total noninterest expense is unchanged at $3.3
       -------------------                                                 
  million for the nine months ended March 31, 1996 and 1995.  Compensation and
  benefits increased by $138,000 due to an increase in accrued bonuses, which
  was offset by a decrease in other noninterest expense of $117,000.  The
  decrease in other noninterest expense was due primarily to the general
  decrease in operating expenses, including advertising costs, professional fees
  and other expenses associated with merging First Federal with Hawkeye.

       Net Income.  Net income increased by $609,000, or $2.89 per share, to
       ----------

  compared to the period a year earlier.  In calculating earnings per

  share, the weighted average number of shares outstanding increased during the
  nine month period ended March 31, 1996 to 193,045, including the effect of
  dilutive stock options.  The increase in the weighted average number of
  Heritage Common Stock outstanding was due to certain directors and officers of
  Hawkeye exercising a total of 1,721 stock options.

  Comparison of Operating Results for the Fiscal Years Ended June 30, 1995, 1994
  and 1993

       Interest Income.  Total interest income for the fiscal year ended June
       ---------------                                                       
  30, 1995 was $12.1 million compared to $11.0 million and $12.9 million for the
  fiscal years ended June 30, 1994 and 1993, respectively.  The increase in
  interest income between 1995 and 1994 of $1.1 million was caused primarily by
  an increase in consumer loans receivable and the increase in interest rates
  during the fiscal year increasing the yield of the adjustable-rate mortgage-
  backed securities and short-term investment securities.

       The decrease of $1.9 million from 1993 to 1994 was due primarily to an
  overall decrease in interest rates during the fiscal year.  The overall rate
  on interest-earning assets decreased from 7.48% in 1993 to 6.56% in 1994.

       Interest Expense.  Total interest expense for Hawkeye for the fiscal year
       ----------------                                                         
  ended June 30, 1995 was $6.7 million compared to $5.7 million and $6.8 million
  for the fiscal years ended June 30, 1994 and 1993, respectively.  The
  composition of total interest expense consisted of interest paid on savings
  deposits, which totaled $6.7 million, $5.7 million and $6.7 million for the
  fiscal years ended June 30, 1995, 1994 and 1993, respectively, and interest on
  borrowed money, which totaled $15,000, $21,000 and $129,000 for the fiscal
  years ended June 30, 1995, 1994 and 1993, respectively.  The increase in
  interest on savings deposits between 1995 and 1994 was caused primarily by the
  increase in market interest rates during the fiscal year and change in mix of
  deposits toward higher earning certificate of deposit accounts.  The decrease
  in interest on savings deposits between 1994 and 1993 was caused primarily by
  a decrease in certificate of deposit accounts and a decrease in market
  interest rates during the fiscal year.  The interest on borrowed money for the
  fiscal year ended June 30, 1993 was due to Heritage borrowing money to
  facilitate the purchase of First Federal.

       Although market interest rates have fluctuated over the past three years,
  Hawkeye has maintained a relatively consistent interest rate spread of 2.93%,
  2.93% and 3.28% for the fiscal years ended June 30, 1995, 1994 and 1993,
  respectively.

       Provision for Loan Losses.  The provision for loan losses was $40,000 for
       -------------------------                                                
  the fiscal year ended June 30, 1995 compared to a reduction in the allowance
  of $130,000 for each of the fiscal years ended June 30, 1994 and 1993.  The
  loan loss provision was provided by Hawkeye in order to reserve against
  potential losses from present to future dispositions of foreclosed and
  repossessed assets and loan losses.  The reduction of the allowance was due to
  management reviewing its loan loss reserve position and determining that the
  reserve was more than adequate after the acquisition of First Federal, based
  on loss experience known and inherent risk in the loan portfolio, prevailing
  market conditions, and management's judgment as to total loan portfolio
  collectibility.

       Noninterest Income.  Noninterest income decreased to $329,000 for the
       ------------------                                                   
  fiscal year ended June 30, 1995 compared to $902,000 and $857,000 for the
  fiscal years ended June 30, 1994 and 1993, respectively.  The $573,000
  decrease between 1995 and 1994 was due primarily to a loss on the sale of
  interest-earning assets of $197,000 as compared to a gain of $189,000 in 1994.

       Noninterest Expense.  Noninterest expense for the fiscal year ended June
       -------------------                                                     
  30, 1995 was $4.4 million compared to $4.7 million and $3.8 million for the
  fiscal years ended June 30, 1994 and 1993, respectively.  The decrease of
  $210,000 between 1995 and 1994 was due primarily to the $51,000 decrease in
  compensation, payroll taxes and fringe benefits and a $252,000 decrease in
  unrealized loss from loans held for sale.  These decreases were offset by a
  general increase in other expenses caused partially by expenses associated
  with merging First Federal with Hawkeye.  The increase in noninterest expense
  between 1994 and 1993 of $880,000 was primarily due to a $231,000 increase in
  compensation and benefits, a $213,000 net gain from foreclosed real estate in
  1993 compared to a net loss of $9,000 in 1994 and a $284,000 increase in
  unrealized loss from loans held for sale.  The unrealized loss on

                                       68
<PAGE>
 
  loans held for sale was caused by an increase in interest rates during the
  time period in which the loans were being held for sale.

       Net Income.  Net income for Heritage for the fiscal year ended June 30,
       ----------                                                             
  1995 was $826,000, or $4.64 per share, compared to $1.9 million, or $10.84 per
  share, and $2.4 million, or $13.89 per share, for the fiscal years ended June
  30, 1994 and 1993, respectively.

       In calculating earnings per share, the weighted average number of shares
  of Heritage Common Stock outstanding was 177,969 at June 30, 1995 compared to
  175,676 and 173,686 at June 30, 1994 and 1993, respectively.  The increase in
  the weighted average number of outstanding shares was due to certain officers
  and directors exercising stock options.

  Impact of New Accounting Standards

       The Financial Accounting Standards Board has approved for the year ending
  June 30, 1996, Statement No. 114, Accounting by Creditors for Impairment of a
  Loan and Statement No. 118 which amended certain provisions of Statement No.
  114 with respect to income recognition and disclosures.  The Financial
  Accounting Standards Board has also approved Statement No. 121, Accounting for
  Impairment of Long-Lived Assets or Long-Lived Assets to Be Disposed Of,
  Statement No. 122, Accounting for Mortgage Servicing Rights and Statement No.
  123, Accounting for Stock-Based Compensation, which are effective for years
  beginning after December 15, 1995.  Adoption of Statements 114, 118, 121, 122
  and 123 are not expected to have a material adverse effect on the Company's
  financial statements when adopted.

  Liquidity

       The ability of Hawkeye to satisfy its short-term commitments requires the
  maintenance of adequate liquidity.  Liquidity is the ability to generate
  sufficient cash to meet loan commitments, savings withdrawals and maturing
  liabilities.  Funds to meet these demands are obtained from conversion of
  assets to cash, savings in-flows, loan principal payments, interest payments,
  advances from the FHLB and the ability of Hawkeye to obtain other funds in the
  marketplace.  In addition, OTS regulations require all thrift institutions to
  maintain a certain percentage of their assets in short-term investments.
  Liquidity management requires the monitoring of portfolio maturities, future
  commitments and the relative cost of funds in the marketplace.  Hawkeye is in
  compliance with federal regulatory liquidity requirements.

       As of June 30, 1995, $10.7 million, or 6.04% of assets, were in interest
  or noninterest-bearing deposits, an additional $25.6 million, or 14.42% of
  assets, were invested in securities available for sale or held to maturity,
  and $36.6 million, or 20.59% of assets, were invested in mortgage-backed
  securities held to maturity.

       The ability of Hawkeye to declare and pay dividends to the Company is
  limited by regulatory restrictions.  See "Regulation -- Federal Regulation of
  Hawkeye -- Dividend Limitations."

  Asset/Liability Management and Interest Rate Sensitivity

       Hawkeye continuously monitors its asset and liability sensitivity to
  interest rates.

       Hawkeye concentrates on originating mortgage loans with typical interest
  adjustment periods of three years or less, or which mature in seven years or
  less, and consumer loans with maturities of five years or less.  Generally,
  Hawkeye no longer originates long-term, fixed-rate loans unless they qualify
  for sale in the secondary market.  Hawkeye also invests its excess cash in
  U.S. Government obligations, which typically mature within five years.

       Interest rate sensitivity management (management of rate sensitive
  interest-earning assets and rate sensitive interest-bearing liabilities)
  focuses on maintaining stability of the net interest margin by matching rate
  sensitive sources of funds with compatible rate sensitive uses of funds.  The
  effective matching of interest-earning assets and

                                       69
<PAGE>
 
  interest-bearing liabilities is necessary to achieve satisfactory financial
  results for Hawkeye.  Such matching has been necessitated by changes in the
  financial markets, government deregulation, economic volatility and customer
  awareness of alternative investments.

       With the current customer trend toward shorter term market rate
  investments, Hawkeye's portfolio has become even more sensitive to interest
  rate fluctuation.  To more properly match interest-earning assets with these
  liabilities, Hawkeye has developed a plan to shorten the maturities of rate
  sensitive assets.  This plan includes the sale of fixed-rate loans, the
  purchase and origination of variable interest rate loans with shorter
  maturities, the origination of shorter-term consumer loans and the purchase of
  government obligations with shorter maturities of one-to-five years.

       The matching of assets and liabilities may be analyzed by examining the
  extent to which such assets and liabilities are "interest rate sensitive" and
  by monitoring an institution's interest rate sensitivity "gap."  An asset or
  liability is said to be interest rate sensitive within a specified time period
  if it will mature or reprice within that period.  The interest rate
  sensitivity gap is defined as the difference between the amount of interest-
  earning assets maturing or repricing within a specific time period and the
  amount of interest-bearing liabilities maturing or repricing within that time
  period.  A gap is considered positive when the amount of interest rate
  sensitive assets exceeds the amount of interest rate sensitive liabilities,
  and is considered negative when the amount of interest rate sensitive
  liabilities exceeds the amount of interest rate sensitive assets.  Generally,
  during a period of rising interest rates, a negative gap would adversely
  affect net interest income while a positive gap would result in an increase in
  net interest income, while conversely during a period of falling interest
  rates, a negative gap would result in an increase in net interest income,
  while a positive gap would negatively affect net interest income.

       The following table presents Hawkeye's interest sensitivity gap between
  interest-earning assets and interest-bearing liabilities at March 31, 1996.
  Prepayment rates on loans and decay rates on deposits are based upon
  assumptions used by the OTS.

                                   REGULATION

       As a federally chartered and federally insured savings association,
  Hawkeye is subject to extensive regulation.  Lending activities and other
  investments must comply with various statutory and regulatory capital
  requirements.  Hawkeye is regularly examined by its federal regulators and
  files periodic reports concerning Hawkeye's activities and financial
  condition.  Hawkeye's relationship with its depositors and borrowers also is
  regulated to a great extent by federal and state laws, especially in such
  matters as the ownership of savings accounts and the form and content of the
  Hawkeye's mortgage documents.

  Federal Regulation of Hawkeye

       The OTS has extensive authority over the operations of all insured
  savings associations.  As part of this authority, Hawkeye is required to file
  periodic reports with the OTS and is subject to periodic examinations by the
  OTS and the FDIC.

       The OTS has established a schedule for the assessment of fees upon all
  savings associations to fund the operations of the OTS.  A schedule of fees
  has also been established for the various types of applications and filings
  made by savings associations with the OTS.  The general assessment, to be paid
  on a semi-annual basis, is computed upon the savings association's total
  assets, including consolidated subsidiaries, as reported in the association's
  latest quarterly thrift financial report.  Savings associations that are
  classified as "troubled" (i.e., having a supervisory rating of "4" or "5" or
  subject to a conservatorship) are required to pay a 50% premium over the
  standard assessment.  For the first half of 1996, Hawkeye's assessment under
  the semi-annual assessment procedure was $27,000.

       The investment and lending authority of Hawkeye is prescribed by federal
  laws and regulations, and Hawkeye is prohibited from engaging in any
  activities not permitted by such laws and regulations.  These laws and
  regulations generally are applicable to all federally chartered savings
  associations and many also apply to state-chartered savings associations.

       Among other things, OTS regulations provide that no savings association
  may invest in corporate debt securities not rated in one of the four highest
  rating categories by a nationally recognized rating organization.  In
  addition, the HOLA provides that loans secured by nonresidential real property
  may not exceed 400% of regulatory capital, subject to increase by the OTS on a
  case-by-case basis.

       Hawkeye is subject to limitations on the aggregate amount of loans that
  it can make to any one borrower, including related entities.  Applicable
  regulations generally do not permit loans-to-one borrower to exceed 15% of
  unimpaired capital and surplus, provided that loans in an amount equal to an
  additional 10% of unimpaired capital and surplus also may be made to a
  borrower if the loans are fully secured by readily marketable securities.  The
  OTS by regulation has amended the loans-to-one borrower rule to permit savings
  associations meeting certain requirements, including fully phased-in capital
  requirements, to extend loans-to-one borrower in additional amounts under
  circumstances limited essentially to loans to develop or complete residential
  housing units.  At March 31, 1996, Hawkeye's lending limit under this
  restriction was $2.3 million.

       Proposed Federal Legislation.  Currently, Congress has under
  consideration various proposals which, if implemented, would have a material
  effect on the financial institutions in general, and Hawkeye in particular.
  These proposals include, among others: (i) the consolidation of the four
  Federal banking agencies (the Federal Reserve Board, OTS, FDIC, and the Office
  of the Comptroller of the Currency), (ii) the imposition of a one-time
  assessment on all SAIF-member institutions, like Hawkeye (See "-- Insurance of
  Accounts") and (iii) requiring all thrifts, like Hawkeye, to convert to a
  national or state bank charter (which may result in adverse income tax
  consequences if a thrift's bad debt reserve would be required to be recaptured
  into taxable income).  The outcome of these various proposals is uncertain and
  Hawkeye is unable to determine the extent to which legislation, if enacted,
  would affect its business.

                                       71

       Federal Home Loan Bank System.  The FHLB System, consisting of 12 FHLBs,
  now is under the jurisdiction of the Federal Housing Finance Board ("FHFB").
  The designated duties of the FHFB are to:  supervise the FHLBs; ensure that
  the FHLBs carry out their housing finance mission; ensure that the FHLBs
  remain adequately capitalized and able to raise funds in the capital market;
  and ensure that the FHLBs operate in a safe and sound manner.

       Hawkeye, as a member of the FHLB of Des Moines, is required to acquire
  and hold shares of capital stock in the FHLB of Des Moines equal to the
  greater of (i) 1.0% of the aggregate outstanding principal amount of
  residential mortgage loans, home purchase contracts and similar obligations at
  the beginning of each year, or (ii) 1/20 of its advances (borrowings) from the
  FHLB of Des Moines.  Hawkeye complied with this requirement with an investment
  in FHLB of Des Moines stock of $1.5 million at March 31, 1996.

       Among other benefits, the FHLB provides a central credit facility
  primarily for member institutions.  It is funded primarily from proceeds
  derived from the sale of consolidated obligations of the FHLB System.  It
  makes advances to members in accordance with policies and procedures
  established by the FHFB and the Board of Directors of the FHLB of Des Moines.
  At March 31, 1996, Hawkeye had $10 million in advances from the FHLB of Des
  Moines.

       Liquidity.  Under OTS regulations, a member thrift institution is
  required to maintain an average daily balance of liquid assets (cash, certain
  time deposits and savings accounts, bankers' acceptances, and specified U.S.
  Government, state or federal agency obligations and certain other investments)
  equal to a monthly average of not less than a specified percentage of its net
  withdrawable accounts plus short-term borrowings.  This liquidity requirement,
  which is currently 5% may be changed from time to time by the OTS  depending
  upon economic conditions and the deposit flows of member associations.
  Existing OTS regulations also require each member institution to maintain an
  average daily balance of short-term liquid assets at a specified percentage
  (currently 1%) of the total of its net withdrawable savings accounts and
  borrowings payable in one year or less.  Monetary penalties may be imposed for
  failure to meet liquidity requirements.  Hawkeye's average liquidity ratio for
  the month of March, 1996 was 23.93%, which exceeded the applicable
  requirements.  Hawkeye has never been subject to monetary penalties for
  failure to meet its liquidity requirements.

       Insurance of Accounts.  The deposits of Hawkeye are presently insured by
  the SAIF, which together with the BIF are the two insurance funds administered
  by the FDIC.  As a result of the BIF reaching its statutory reserve ratio, the
  FDIC revised the premium schedule for BIF insured institutions to provide a
  range of .04% to .31% of deposits.  The revisions became effective in the
  third quarter of 1995.  The BIF premium schedule was further revised,
  effective January 1996, to provide a range of 0% to .27% with an annual
  minimum assessment of $2,000, essentially eliminating deposit insurance
  premiums for many BIF-insured institutions.  As a result of these adjustments,
  BIF insured institutions now generally pay lower premiums than SAIF insured
  institutions.

       The FDIC has stated that the SAIF is not expected to attain its
  designated reserve ratio until the year 2002.  As a result, SAIF insured
  members will generally be subject to higher deposit insurance premiums than
  BIF insured institutions until, all things being equal, the SAIF attains its
  required reserve ratio.

       The effect of this disparity on Hawkeye and other SAIF members is
  uncertain at this time.  It may have the effect of permitting BIF members
  banks to offer loan and deposit products on more attractive terms that SAIF
  members due to the cost savings achieved through lower premiums, thereby
  placing SAIF at a competitive disadvantage.  In order to eliminate this
  disparity, a number of proposals to recapitalize the SAIF have been considered
  recently by the United States Congress.  One plan under current consideration
  by the United States Congress provides for a one-time assessment to be imposed
  on all deposits assessed at the SAIF rates, as of March 31, 1995, in order to
  recapitalize the SAIF to a level equal to 1.25% of insured deposits and
  eliminate the disparity.  The special assessment rate under such plan is
  anticipated to range from .80% to .90%.  Based on Hawkeye's level of SAIF
  deposits at March 31, 1995, and assuming a special assessment of .85%,
  Hawkeye's assessment would be

                                       72
<PAGE>
 
      
  approximately $1.3 million on a pre-tax basis.  Accordingly, this special
  assessment would significantly increase noninterest expense and adversely
  affect Hawkeye's results of operation.  Conversely, depending on Hawkeye's
  capital level and supervisory rating, and assuming, although there can be no
  assurance, that if the insurance premium levels for BIF and SAIF members are
  again equalized, deposits insurance premiums could decrease significantly to
  the minimum assessment for future periods.     

       The United States Congress is also considering legislation that would
  require all Federal thrift institutions such as Hawkeye, to either convert to
  a national bank or a state charted depository institution by January 1, 1998.
  The OTS would also be abolished and its functions transferred among the other
  federal banking regulators.  Certain aspects of the legislation remain to be
  resolved and therefore no assurance can be given as to whether or in what form
  the legislation will be enacted or its effect on Heritage and Hawkeye.  See
  "Information Concerning the Special Meeting -- Recent Events -- Deposit
  Insurance Premiums".

       The FDIC may terminate the deposit insurance of any insured depository
  institutions if it determines after a hearing that the institutions has
  engaged or is engaging in unsafe or unsound practices, is in an unsafe or
  unsound condition to continue operations, or has violated any applicable law,
  regulation, order or any condition imposed by an agreement with the FDIC.  It
  also may suspend deposit insurance temporarily during the hearing process for
  the permanent termination of insurance, if the institution has no tangible
  capital.  If insurance of accounts is terminated, the accounts at the
  institution at the time of termination, less subsequent withdrawals, shall
  continue to be insured for a period of six months to two years, as determined
  by the FDIC.  Management is aware of no existing circumstances which could
  result in termination of the deposit insurance of Hawkeye.

       Prompt Corrective Action.  Under Section 38 of the FDIA, as added by the
  Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), each
  federal banking agency is required to implement a system of prompt corrective
  action for institutions which it regulates.  In September 1992, the federal
  banking agencies adopted substantially similar regulations which are intended
  to implement the system of prompt corrective action established by Section 38
  of the FDIA, which became effective on December 19, 1992.  Under the
  regulations, an institution shall be deemed to be (i) "well capitalized" if it
  has a total risk-based capital ratio of 10.0% or more, has a Tier I risk-based
  capital ratio of 6.0% or more, has a Tier I leverage capital ratio of 5.0% or
  more and is not subject to specified requirements to meet and maintain a
  specific capital level for any capital measure: (ii) "adequately capitalized"
  if it has a total risk-based capital ratio of 8.0% or more, a Tier I risk-
  based capital ratio of 4.0% or more and a Tier I leverage capital ratio of
  4.0% or more (3.0% under certain circumstances) and does not meet the
  definition of "well capitalized," (iii) "undercapitalized" if it has a total
  risk-based capital ratio that is less than 8.0%, a Tier I risk-based capital
  ratio that is less than 1.0% or a Tier I leverage capital ratio that is less
  than 4.0% (3.0% under certain circumstances), (iv) "significantly
  undercapitalized" if it has a total risk-based capital ratio that is less than
  6.0%, a Tier I risk-based capital ratio that is less than 3.0% or a Tier I
  leverage capital ratio that is less than 3.0% and (v) "critically
  undercapitalized" if it has a ratio of tangible equity to total assets that is
  equal to or less than 2.0%.

       Section 38 of the FDIA and the implementing regulations also provide that
  a federal banking agency may, after notice and an opportunity for a hearing,
  reclassify a well capitalized institution as adequately capitalized and may
  require an adequately capitalized institution or an undercapitalized
  institution to comply with supervisory actions as if it were in the next lower
  category if the institution is in an unsafe or unsound condition or engaging
  in an unsafe or unsound practice.  (The FDIC may not, however, reclassify a
  significantly undercapitalized institution as critically undercapitalized.)

       An institution generally must file a written capital restoration plan
  which meets specified requirements, as well as a performance guaranty by each
  company that controls the institution, with the appropriate federal banking
  agency within 45 days of the date that the institution receives notice or is
  deemed to have notice that it is undercapitalized, significantly
  undercapitalized or critically undercapitalized.  Immediately upon becoming

                                       73
<PAGE>
 
  undercapitalized, an institution shall become subject to the provisions of
  Section 38 of the FDIA, which sets forth various mandatory and discretionary
  restrictions on its operations.

       At March 31, 1996, Hawkeye was a "well capitalized" institution under the
  prompt corrective action regulations of the OTS.

       Standards for Safety and Soundness.  Federal law requires the federal
  banking regulatory agencies to prescribe, by regulation or guideline,
  standards for all insured depository institutions and depository institution
  holding companies relating to: (i) internal controls, information systems and
  internal audit systems; (ii) loan documentation; (iii) credit underwriting;
  (iv) interest rate risk exposure; (v) asset growth; and (vi) compensation,
  fees and benefits.  The OTS, as well as the other federal banking agencies,
  has adopted safety and soundness guidelines on matters such as loan
  underwriting and documentation, internal controls and audit systems, interest
  rate risk exposure and compensation and other employee benefits.  Any
  institution which fails to comply with these standards must submit a
  compliance plan.  A failure to submit a compliance plan or to comply with an
  approved compliance plan will result in further enforcement action against the
  institution.  Savings and loan holding companies are also required to ensure
  that transactions and relationship with their subsidiary savings associations
  do not have a detrimental effect on the safe and sound operation of the
  association.

       Qualified Thrift Lender Test.  All savings associations are required to
  meet a QTL test set forth in Section 10(m) of the HOLA and regulations of the
  OTS thereunder to avoid certain restrictions on their operations.  A savings
  institution that fails to become or remain a QTL shall either become a
  national bank or be subject to the following restrictions on its operations:
  (1) the association may not make any new investment or engage in activities
  that would not be permissible for national banks; (2) the association may not
  establish any new branch office where a national bank located in the savings
  institution's home state would not be able to establish a branch office; (3)
  the association shall not be eligible to obtain new advances from any FHLB;
  and (4) the payment of dividends by the association shall be subject to the
  rules regarding the statutory and regulatory dividend restrictions applicable
  to national banks.  Also, beginning three years after the date on which the
  savings institution ceases to be a qualified thrift lender, the savings
  institution would be prohibited from retaining any investment or engaging in
  any activity not permissible for a national bank and would be required to
  repay any outstanding advances to any FHLB.  In addition, within one year of
  the date on which a savings association controlled by a company ceases to be a
  QTL, the company must register as a bank holding company and, consequently,
  becomes subject to the rules applicable to such companies.  A savings
  institution may requalify as a qualified thrift lender if it thereafter
  complies with the QTL test.

       Currently, the QTL test requires that 65% of an institution's "portfolio
  assets" (as defined) consist of certain housing and consumer-related assets on
  a monthly average basis in nine out of every 12 months.  Assets that qualify
  without limit for inclusion as part of the 65% requirement are loans made to
  purchase, refinance, construct, improve or repair domestic residential housing
  and manufactured housing; home equity loans; mortgage-backed securities (where
  the mortgages are secured by domestic residential housing or manufactured
  housing); FHLB stock; and direct or indirect obligations of the FDIC.  In
  addition, the following assets, among others, may be included in meeting the
  test subject to an overall limit of 20% of the savings institution's portfolio
  assets:  50% of residential mortgage loans originated and sold within 90 days
  of origination; 100% of consumer and educational loans (limited to 10% of
  total portfolio assets); and stock issued by the FHLMC or the FNMA.  Portfolio
  assets consist of total assets minus the sum of (i) goodwill and other
  intangible assets, (ii) property used by the savings institution to conduct
  its business, and (iii) liquid assets up to 20% of the institution's total
  assets.

       At March 31, 1996, Hawkeye complied with the current QTL requirement.

       Capital Requirements.  Under OTS regulations a savings association must
  satisfy three minimum capital requirements: core capital, tangible capital and
  risk-based capital.  Savings associations must meet all of the standards in
  order to comply with the capital requirements.

                                       74
<PAGE>
 
       OTS capital regulations establish a 3% core capital ratio (defined as the
  ratio of core capital to adjusted total assets).  Core capital is defined to
  include common stockholders' equity, noncumulative perpetual preferred stock
  and any related surplus, and minority interests in equity accounts of
  consolidated subsidiaries, less (i) any intangible assets; and (ii) equity and
  debt investments in subsidiaries that are not "includable subsidiaries," which
  is defined as subsidiaries engaged solely in activities not impermissible for
  a national bank, engaged in activities impermissible for a national bank but
  only as an agent for its customers, or engaged solely in mortgage-banking
  activities.  In calculating adjusted total assets, adjustments are made to
  total assets to give effect to the exclusion of certain assets from capital
  and to account appropriately for the investments in and assets of both
  includable and nonincludable subsidiaries.  Institutions that fail to meet the
  core capital requirement would be required to file with the OTS a capital plan
  that details the steps they will take to reach compliance.  In addition, the
  OTS prompt corrective action regulation provides that a savings institution
  that has a core capital leverage ratio of less than 4% (3% for institutions
  receiving the highest CAMEL examination rating) will be deemed to be
  "undercapitalized" and may be subject to certain restrictions.  See "- Prompt
  Corrective Action."

       Savings associations also must maintain "tangible capital" not less than
  1.5% of it's adjusted total assets. "Tangible capital" is defined, generally,
  as core capital minus any "intangible assets."

       Each savings institution must maintain total capital equal to at least 8%
  of risk-weighted assets.  Total capital consists of the sum of core and
  supplementary capital, provided that supplementary capital cannot exceed core
  capital, as previously defined.  Supplementary capital includes (i) permanent
  capital instruments such as cumulative perpetual preferred stock, perpetual
  subordinated debt, and mandatory convertible subordinated debt, (ii) maturing
  capital instruments such as subordinated debt, intermediate-term preferred
  stock and mandatory redeemable preferred stock, subject to an amortization
  schedule, and (iii) general valuation loan and lease loss allowances up to
  1.25% of risk-weighted assets.

       The risk-based capital regulation assigns each balance sheet asset held
  by a savings institution to one of four risk categories based on the amount of
  credit risk associated with that particular class of assets.  Assets not
  included for purposes of calculating capital are not included in calculating
  risk-weighted assets.  The categories range from 0% for cash and securities
  that are backed by the full faith and credit of the U.S. Government to 100%
  for repossessed assets or assets more than 90 days past due.  Qualifying
  residential mortgage loans (including multi-family mortgage loans) are
  assigned a 50% risk weight.  Consumer, commercial, home equity and residential
  construction loans are assigned a 100% risk weight, as are nonqualifying
  residential mortgage loans and that portion of land loans and nonresidential
  construction loans which do not exceed an 80% loan-to-value ratio.  The book
  value of assets in each category is multiplied by the weighing factor (from 0%
  to 100%) assigned to that category.  These products are then totalled to
  arrive at total risk-weighted assets.  Off-balance sheet items are included in
  risk-weighted assets by converting them to an approximate balance sheet
  "credit equivalent amount" based on a conversion schedule.  These credit
  equivalent amounts are then assigned to risk categories in the same manner as
  balance sheet assets and included risk-weighted assets.

       The OTS has incorporated an interest rate risk component into its
  regulatory capital rule.  Under the rule, savings associations with "above
  normal" interest rate risk exposure would be subject to a deduction from total
  capital for purposes of calculating their risk-based capital requirements.  A
  savings association's interest rate risk is measured by the decline in the net
  portfolio value of its assets (i.e., the difference between incoming and
  outgoing discounted cash flows from assets, liabilities and off-balance sheet
  contracts) that would result from a hypothetical 200 basis point increase or
  decrease in market interest rates divided by the estimated economic value of
  the association's assets, as calculated in accordance with guidelines set
  forth by the OTS.  A savings association whose measured interest rate risk
  exposure exceeds 2% must deduct an interest rate component in calculating its
  total capital under the risk-based capital rule.  The interest rate risk
  component is an amount equal to one-half of the difference between the
  institution's measured interest rate risk and 2%, multiplied by the estimated
  economic value of the association's assets.  That dollar amount is deducted
  from an association's total capital in calculating compliance with its risk-
  based capital requirement.  Under the rule, there is a two quarter lag between
  the reporting date of an institution's financial data and the effective date
  for the new capital requirement based on that data.  A savings association
  with

                                       75
<PAGE>
 
  assets of less than $300 million and risk-based capital ratios in excess of
  12% is not subject to the interest rate risk component, unless the OTS
  determines otherwise.  The rule also provides that the Director of the OTS may
  waive or defer an association's interest rate risk component on a case-by-case
  basis.  The OTS has recently postponed the date that the component will first
  be deducted from an institution's total capital until an appeals process is
  developed for the measurement of an institution's interest rate risk.

       The following table presents Hawkeye's capital levels as of March 31,
       1996.

       Dividend Limitations.  OTS regulations require Hawkeye to give the OTS 30
  days' advance notice of any proposed declaration of dividends to Heritage, and
  the OTS has the authority under its supervisory powers to prohibit the payment
  of dividends to the Heritage.  In addition, Hawkeye may not declare or pay a
  cash dividend on its capital stock if the effect thereof would be to reduce
  the regulatory capital of Hawkeye below the amount required for the
  liquidation account.

       OTS regulations impose uniform limitations on the ability of all savings
  associations to engage in various distributions of capital such as dividends,
  stock repurchases and cash-out mergers.  The regulation utilizes a three-
  tiered approach which permits various levels of distributions based primarily
  upon a savings association's capital level.

       A Tier 1 savings association generally has capital in excess of its fully
  phased-in capital requirement (both before and after the proposed capital
  distribution) and has not been notified by the OTS that it is in need of more
  than normal supervision.  A Tier 1 savings association may make (without
  application but upon prior notice to, and no objection made by, the OTS)
  capital distributions during a calendar year up to 100% of its net income to
  date during the calendar year plus one-half its surplus capital ratio (i.e.,
  the amount of capital in excess of its fully phased-in requirement) at the
  beginning of the calendar year.  Capital distributions in excess of such
  amount require advance approval from the OTS.

       A savings association with either (i) capital equal to or in excess of
  its minimum capital requirement but below its fully phased-in capital
  requirement (both before and after the proposed capital distribution), or (ii)
  capital in excess of its fully phased-in capital requirement (both before and
  after the proposed capital distribution) but which has been notified by the
  OTS that it is in need of more than normal supervision may be designated by
  the OTS as a Tier 2 association.  Such an association may make (without
  application) capital distributions up to an amount equal to 75% of its net
  income during the previous four quarters depending on how close the
  association is to meeting its fully phased-in capital requirement.  Capital
  distributions exceeding this amount require prior OTS approval.

                                       76
<PAGE>
 
       Tier 3 associations include savings associations with either (i) capital
  below the minimum capital requirement (either before or after the proposed
  capital distribution), or (ii) capital in excess of the fully phased-in
  capital requirement but which has been notified by the OTS that it shall be
  treated as a Tier 3 association because it is in need of more than normal
  supervision.  Tier 3 associations may not make any capital distributions
  without prior approval from the OTS.

       The OTS issued a proposed rule in December 1994 that would amend its
  capital distributions regulation to incorporate the definition of "capital
  distributions" used under the system of prompt corrective action established
  by FDICIA.  The proposed rule would allow capital distributions without notice
  to the OTS by associations that are adequately capitalized that receive a
  composite rating of 1 or 2, and that are not held by a holding company.  Other
  associations that are at least adequately capitalized after making a capital
  distribution would be permitted to make a capital distribution upon notice to
  the OTS.  Applications for capital distributions would be accepted from
  troubled associations and undercapitalized associations but would be approved
  only under certain restrictive conditions.
 
       Investment Rules.  The OTS permissible amount of loans-to-one borrower
  now follows the national bank standard for all loans made by savings
  institutions.  This standard generally does not permit loans-to-one borrower
  to exceed 15% of unimpaired capital and surplus.  Loans in an amount equal to
  an additional 10% of unimpaired capital and surplus also may be made to a
  borrower if the loans are fully secured by readily marketable securities.
  Hawkeye believes that these provisions have not had any material adverse
  effect on its lending activities.

       Savings institutions and their subsidiaries may not acquire or retain
  investments in corporate debt securities that at the time of acquisition were
  not rated in one of the four highest rating categories by at least one
  nationally recognized rating organization.  Investments in a savings
  institution's portfolio not meeting this requirement must be divested as
  quickly as can be done on a prudent basis, but not later than July 1, 1994.
  Pursuant to regulatory accounting rules, securities subject to divestment are
  not to be treated as "held for sale;" however, GAAP may still require mark-to-
  market accounting by virtue of the divestment requirement.  Hawkeye does not
  hold any investments that must be divested under this provision.

       In addition, the permissible amount of commercial real estate loans for
  federal associations is reduced from the pre-FIRREA standard of 40% of assets
  to an amount equal to four times capital.  This limitation is not expected to
  have a material adverse effect on Hawkeye.

       At March 31, 1996, the largest loan by Hawkeye outstanding to any one
  borrower, including related entities, was the Bennett Funding Asset with a
  balance at that date of $1.8 million.  For additional information, see
  "Information Concerning the Special Meeting -- Recent Events -- Bennett
  Funding Asset".

       Activities of Savings Associations and Their Subsidiaries.  OTS
  regulations provide that, when a savings association establishes or acquires a
  subsidiary or elects to conduct any new activity through a subsidiary that the
  association controls, the savings association shall notify the FDIC and the
  OTS 30 days in advance and provide the information each agency may, by
  regulation, require.  Savings associations also must conduct the activities of
  subsidiaries in accordance with existing regulations and orders.
      
       Accounting and Regulatory Standards.  An OTS policy statement applicable
  to all savings associations clarifies and re-emphasizes that the investment
  activities of a savings association must be in compliance with approved and
  documented investment policies and strategies, and must be accounted for in
  accordance GAAP. Under the policy statement, management must support its
  classification of an accounting for loans and securities (i.e., whether held
  for investment, sale or trading) with appropriate documentation. Hawkeye is in
  compliance with these amended rules.     

                                       77
<PAGE>
 
       The OTS has adopted an amendment to its accounting regulations, which may
  be made more stringent than generally accepted accounting principles by the
  OTS, to require that transactions be reported in a manner that best reflects
  their underlying economic substance and inherent risk and that financial
  reports must incorporate any other accounting regulations or orders prescribed
  by the OTS.

       Investment Portfolio Policy.  OTS supervisory policy requires that
  securities owned by thrift institutions must be classified and reported in
  accordance with FASB 115.

       Transactions with Affiliates.  Savings associations must comply with
  Sections 23A and 23B of the Federal Reserve Act ("Sections 23A and 23B")
  relative to transactions with affiliates in the same manner and to the same
  extent as if the savings association were a Federal Reserve member bank.
  Generally, Sections 23A and 23B:  (i) limit the extent to which the insured
  association or its subsidiaries may engage in certain covered transactions
  with an affiliate to an amount equal to 10% of such institution's capital and
  surplus and place an aggregate limit on all such transactions with affiliates
  to an amount equal to 20% of such capital and surplus, and (ii) require that
  all such transactions be on terms substantially the same, or at least as
  favorable to the institution or subsidiary, as those provided to a non-
  affiliate.  The term "covered transaction" includes the making of loans,
  purchase of assets, issuance of a guaranty and similar other types of
  transactions.

       Three additional rules apply to savings associations:  (i) a savings
  association may not make any loan or other extension of credit to an affiliate
  unless that affiliate is engaged only in activities permissible for bank
  holding companies;  (ii) a savings association may not purchase or invest in
  securities issued by an affiliate (other than securities of a subsidiary); and
  (iii) the OTS may, for reasons of safety and soundness, impose more stringent
  restrictions on savings associations but may not exempt transactions from or
  otherwise abridge Section 23A or 23B.  Exemptions from Section 23A or 23B may
  be granted only by the Federal Reserve Board, as is currently the case with
  respect to all FDIC-insured banks.  Hawkeye has not been significantly
  affected by the rules regarding transactions with affiliates.

  Regulation of Heritage
      
       Heritage is a unitary savings and loan holding company within the meaning
  of the Home Owner's Loan Act ("HOLA"). As such, Heritage is registered with
  the OTS and subject to OTS regulations, examinations, supervision and
  reporting requirements. Heritage is required to file certain reports with, and
  otherwise comply with the regulations of, the OTS. As a subsidiary of a
  savings and loan holding company, Hawkeye is subject to certain restrictions
  in its dealings with the Heritage and with other companies affiliated with
  Heritage and also are subject to regulatory requirements and provisions as
  federal institutions.     

       Affiliate Restrictions.  The affiliate restrictions contained in Section
  23A and 23B of the Federal Reserve Act apply to all federally insured savings
  associations and any such "affiliate".  A savings and loan holding company,
  its subsidiaries and any other company under common control are considered
  affiliates of the subsidiary savings association under the HOLA.
      
       Qualified Thrift Lender Test.  The HOLA requires any savings and loan
  holding company that controls a savings association that fails the QTL test,
  as explained under "-- Federal Regulation of Hawkeye -- Qualified Thrift
  Lender Test," must, within one year after the date on which the association
  ceases to be a QTL, register as and be deemed a bank holding company subject
  to all applicable laws and regulations.

       The payment of dividends by Commercial and Heritage 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 Nebraska
  law, dividends may be paid in cash, in property or in shares of capital stock
  only out of unreserved and 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, 1996), and the only significant sources of funds available for
  the payment of dividends by Heritage are dividends paid by Hawkeye to
  Heritage.  Under regulations of the OTS, neither the Bank nor Hawkeye 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 Hawkeye are required to
  give the OTS 30 days' prior notice of any proposed declaration of a dividend
  to Commercial and Heritage, 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 Heritage
  Common Stock, whose rights are presently governed by Iowa law and Heritage's
  Articles of Incorporation and Bylaws, and indirectly by Hawkeye's Charter and
  Bylaws, will become stockholders of Commercial, a Nebraska corporation.
  Accordingly, their rights will be governed by Nebraska law and the Articles of
  Incorporation and Bylaws of Commercial and indirectly by the Bank's Charter
  and Bylaws.  Certain differences arise from the differences between Iowa and
  Nebraska corporate law, between the Articles of Incorporation and Bylaws of
  Heritage and the Articles of Incorporation and Bylaws of Commercial and
  between the Charter and Bylaws of Hawkeye 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 Articles of Incorporation and
  Bylaws of Commercial and the Articles of Incorporation and Bylaws of Heritage.
  See "Available Information."
      
       Issuance of Capital Stock.  The Articles of Incorporation of Commercial
  authorize the issuance of 25,000,000 shares of Commercial Common Stock and
  10,000,000 shares of preferred stock, par value $0.01 per share.  The Articles
  of Incorporation of Heritage authorize the issuance of 5,000,000 shares of
  Heritage Common Stock and 1,000,000 shares of preferred stock, par value $1.00
  per share. At August 12, 1996, 15,094,136 and 180,762 shares of Commercial
  Common Stock and Heritage Common Stock, respectively, were issued and
  outstanding.      

                                       82
<PAGE>
 
  outstanding. Neither Commercial nor Heritage had any shares of preferred 
  stock outstanding. Under Commercial's Articles of Incorporation and Heritage's
  Articles of Incorporation, Commercial and Heritage are authorized to issue
  additional shares of capital stock up to the authorized without stockholders
  approval.

       Voting Rights.  Holders of the Commercial Common Stock are entitled to 
  one vote per share on all matters submitted to a vote of stockholders, other
  than in the election of directors, where voting rights are cumulative. Holders
  of Heritage Common Stock are also entitled to one vote per share on all
  matters submitted to a vote of stockholders. Pursuant to Heritage's Articles
  of Incorporation, however, Heritage stockholders are not entitled to cumulate
  their votes in the election of directors.
 
       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
  Heritage's stock may be called by the President of Heritage, by the Board of
  Directors or by the holders of ten percent (10%) or more of the shares of
  Heritage Common Stock entitled to vote at such meeting.

       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
  Stockholders" (as defined in the Articles of Incorporation).  Heritage's Board
  of Directors consists of seven persons, divided into three classes in nearly
  equal number as possible.  The authorized number of Directors of Heritage may
  only be changed by an amendment to the Bylaws, which requires Board action.

       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.  Heritage's Bylaws provide 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 Heritage.  In order to make any such nomination or
  proposal, a stockholder must give notice in writing, delivered or mailed to
  the Secretary of Heritage, not less than ten nor more than 15 days prior to
  such meeting, together with certain information relating to the nomination or
  proposal.

       Approval of Mergers, Consolidations, Sale of Substantially All Assets and
  Dissolutions.  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.  Heritage's Articles of Incorporation do not contain
  any approval requirements for mergers or similar corporate action, other than
  those imposed by Iowa law generally.

       Limitations on Directors' Liability. The Nebraska Business Corporation
  Act does not expressly limit or eliminate the liability of directors. However,
  Commercial's Articles of Incorporation provide that an "outside director"
  shall not be personally liable to the respective corporation or its
  stockholders for monetary damages for 

                                       83
<PAGE>
 
  breach of his fiduciary duty as a director and authorizes the respective 
  corporation to indemnify such outside director against monetary damages for 
  such breach to the full extent permitted by law. This provision 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 injuctive order obtained by the respective
  corporation or its stockholders. "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 the respective corporation through management agreements,
  voting trusts, directorships in related corporation or any other device or
  relationship. Heritage's Articles of Incorporation provide that its directors
  will not be liable to Heritage or its stockholders for monetary damages for
  breach of fiduciary duty as a director with the exceptions of: (i) breaches of
  a director's duty of loyalty to Heritage or its stockholders; (ii) acts or
  omissions that are not in good faith or that involve intentional misconduct or
  a knowing violation of law; (iii) for any transactions from which the director
  derives an improper personal benefit; or (iv) due to Section 496A.44 of the
  IBCA.

       Amendment of Articles 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 Commercial 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.
  Heritage's Articles of Incorporation do not contain limitations on amendment.
  As such, Heritage's Articles of Incorporation may be amended only in
  accordance with Iowa law, which requires the Board of Directors to adopt a
  resolution setting forth the proposed amendment, which must then be approved
  by a majority vote of the stockholders entitled to vote on the proposed
  amendment except for certain immaterial amendments.

       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 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 Commercial Common Stock as of the date of adoption of the Rights
  Plan and certain persons who

                                       84
<PAGE>
 
  acquire their shares directly from Commercial) has acquired, or has obtained
  the right to acquire, beneficial ownership of 15% or more of the outstanding
  shares of Commercial Common Stock and has not complied with the procedural
  requirements set forth in the Rights Plan (such person being referred to as a
  "15% Person").  Secondary Rights will become exercisable upon the earlier of
  (i) one business day following a public announcement that any person (other
  than Commercial or certain related entities) has acquired, or has obtained the
  right to acquire, beneficial ownership of 25% or more of the outstanding
  shares of Commercial Common Stock, provided that such acquisition is not
  deemed a "Fair Offer," as described in the Rights Plan (such person being
  known as a "25% Person"), or (ii) one business day following the commencement
  of a tender offer, other than a Fair Offer, or exchange offer, the
  consummation of which would result in the beneficial ownership of 25% or more
  of the outstanding shares of Commercial Common Stock by any person other than
  Commercial or certain related entities.  A public announcement for this
  purpose shall be made by Commercial or, as the case may be, by a 15% Person or
  a 25% Person.

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

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

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

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

                                       85
<PAGE>
 
       The terms of the Rights may be amended by the Board of Directors of
  Commercial without the consent of the holders of the Rights, except that
  following the date on which the Rights become exercisable, such amendment may
  not adversely affect the interests of the holders of the Rights.

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

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

       Heritage does not have any similar shareholder rights plan.


                         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 cannot be approved unless the Special Meeting is
  adjourned in order to permit further solicitation of proxies and the necessary
  votes are obtained.  In order to allow proxies that have been received by
  Heritage at the time of the Special Meeting to be voted for such adjournment,
  if necessary, Heritage has submitted the question of adjournment under such
  circumstances to its stockholders as a separate matter for their
  consideration.  A majority of the shares of Heritage Common Stock represented
  and voting at the Special Meeting is required in order to approve any such
  adjournment.  The Board of Directors of Heritage 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.

       Heritage'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.


                                 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 Kantarian & Bronstein, P.C., Washington, D.C.,
  and for Heritage by Breyer & Aguggia, Washington, D.C.

                         INDEPENDENT AUDITOR'S REPORT




To the Board of Directors
Heritage Financial, Ltd.
Boone, Iowa

We have audited the accompanying consolidated statements of
financial condition of Heritage Financial, Ltd. and subsidiaries
as of June 30, 1995 and 1994, and the related consolidated
statements of income, stockholders' equity, and cash flows for
each of the three years in the period ended June 30, 1995. These
financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred
to above present fairly, in all material respects, the financial
position of Heritage Financial, Ltd. and subsidiaries as of June
30, 1995 and 1994, and the results of their operations and their
cash flows for each of the three years in the period ended June
30, 1995, in conformity with generally accepted accounting
principles.

As described in Note 1 to the consolidated financial statements,
during the year ended June 30, 1994 the Company changed its
methods of accounting for income taxes and certain investments
in debt and equity securities to adopt Financial Accounting
Standards Board Statement No.'s 109 ("Accounting for Income
Taxes") and 115 ("Accounting for Certain Investments in Debt and
Equity Securities"), respectively.

Note 1.  Significant Accounting Policies

Organization and Nature of Business: Heritage Financial, Ltd. is a holding
- ------------------------------------
company which owns 100% of the stock of its subsidiary, Hawkeye Federal Savings
Bank (Hawkeye Federal). Hawkeye Federal Savings Bank is a federally chartered
savings bank that conducts its operations from its main office located in Boone,
Iowa and five branch offices located in Carroll, Madrid, Ogden, Lake City, and
Manning, Iowa.

Prior to March 31, 1995, the Company had two savings bank subsidiaries, Hawkeye
Federal and First Federal Savings Bank (First Federal), Carroll, Iowa. Effective
March 31,1995, First Federal was merged with and into Hawkeye Federal. The
assets and liabilities transferred to Hawkeye Federal were transferred at
historical cost.

Principles of consolidation: The accompanying consolidated financial statements
- ----------------------------
include the accounts of the Company and its wholly-owned subsidiary, Hawkeye
Federal Savings Bank and, for periods prior to the merger of Hawkeye Federal and
First Federal, the accounts of First Federal.

All significant intercompany balances and transactions have been eliminated in
consolidation.

Cash: Cash consists of cash on hand and interest-bearing and non-interest-
- -----
bearing deposits in banks. All certificates of deposit, regardless of maturity,
are considered to be other investments.

Investment in securities and mortgage-backed securities: The Company elected to
- --------------------------------------------------------
adopt the provisions of FASB Statement No. 115, "Accounting for Certain
Investments in Debt and Equity Securities", as of June 30, 1994. In accordance
with Statement No. 115, the comparative financial statements prior to this date
have not been restated for the change in accounting principle. The June 30, 1994
balance of stockholders' equity was increased by $5,933, net of the $1,388
related deferred tax affect, to recognize the net unrealized holding gain on
securities as of June 30, 1994.

Statement 115 requires that management determine the appropriate classification
of securities at the date of adoption, and thereafter at the date individual
investment securities are acquired. The classifications are as follows:

  Securities and mortgage-backed securities held to maturity: Securities and
  -----------------------------------------------------------
  mortgage-backed securities classified as held to maturity are carried at cost
  adjusted for amortization of premium and accretion of discount using a method
  that approximates the level yield method.

  Securities available for sale: Securities classified as available for sale are
  ------------------------------
  those instruments that the Company intends to hold for an indefinite period of
  time, but not necessarily to maturity. Any decision to sell a security
  classified as available for sale would be based on various factors, including
  significant movements in interest rates, changes in the maturity mix of the
  Company's assets and liabilities, liquidity needs, regulatory capital
  considerations, and other similar factors. Securities available for sale are
  carried at fair value. Unrealized gains or losses are reported as increases or
  decreases in stockholders' equity, net of the related deferred tax effect.
  Realized gains or losses, determined on the basis of the cost of specific
  securities sold, are included in earnings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS                                     
- --------------------------------------------------------------------------------

Prior to the adoption of Statement 115, the Company carried its debt securities
at amortized cost. Equity securities were stated at the lower of their aggregate
cost or market and mortgage-backed securities which were designated as held for
sale were carried at the lower of aggregate cost or estimated market value.

Loans held for sale: Mortgage loans originated and intended for sale in the
- --------------------
secondary market are carried at the lower of aggregate cost or estimated market
value. Loans held for sale which are transferred to loans receivable are
transferred at the lower of aggregate cost or estimated market value at the date
of transfer. Net unrealized losses are recognized in a valuation allowance
through charges to income.

Lending activities: The Company grants residential, commercial, real estate, and
- -------------------
consumer loans to customers meeting Board approved underwriting guidelines,
primarily in the Carroll and Boone County, Iowa areas and through established
correspondent lending relationships. Generally, these loans are collateralized
by real estate or other personal property.

Loans receivable: Loans receivable are stated at unpaid principal balances, less
- -----------------
an allowance for loan losses, and net deferred loan origination fees, costs and
discounts.

Discounts on first mortgage loans are amortized to income using the interest
method over the remaining period to contractual maturity, adjusted for
prepayments. Discounts on consumer loans are recognized over the lives of the
loans using methods that approximate the interest method.

The allowance for loan losses is established through a provision for loan losses
charged to expense. Loans are charged against the allowance for loan losses when
management believes that collectibility of the principal is unlikely. The
allowance is an amount that management believes will be adequate to absorb
estimated losses on existing loans that may become uncollectible, based on
evaluation of the collectibility of loans and prior loss experience. This
evaluation also takes into consideration such factors as changes in the nature
and volume of the loan portfolio, overall portfolio quality, review of specific
problem loans, and current economic conditions that may affect the borrower's
ability to pay. While management uses the best information available to make its
evaluation, future adjustments to the allowance may be necessary if there are
significant changes in economic conditions.

Uncollectible interest on loans that are contractually past due is charged off
or an allowance is established based on management's periodic evaluation. The
allowance is established by a charge to interest income equal to all interest
previously accrued, and income is subsequently recognized only to the extent
cash payments are received until, in management's judgment, the borrower's
ability to make periodic interest and principal payments is no longer in doubt,
in which case the loan is returned to accrual status.

Loan origination and related costs: Loan fees and certain direct loan
- -----------------------------------
origination costs are deferred, and the net fee or cost is recognized as an
adjustment to interest income using the interest method over the contractual
life of the loans, adjusted for estimated prepayments based on the Company's
historical prepayment experience.

Foreclosed real estate: Real estate properties acquired through loan foreclosure
- -----------------------
are initially recorded at the lower of cost or fair value less estimated selling
expenses at the date of foreclosure. Costs relating to development and
improvement of property are capitalized, whereas costs relating to holding
property are expensed.

Valuations are periodically performed by management. If the carrying value of a
property exceeds its estimated fair value less estimated selling expenses,
either an allowance for losses is established, or the property's carrying value
is reduced, by a charge to income.

Income taxes: Beginning July 1, 1993, deferred taxes are provided on a liability
- -------------
method (FASB Statement No. 109) whereby deferred tax assets are recognized for
deductible temporary differences and operating loss and tax credit carryforwards
and deferred tax liabilities are recognized for taxable temporary differences.
Temporary differences are the difference between the reported amounts of assets
and liabilities and their income tax bases. Deferred tax assets are reduced by a
valuation allowance when, in the opinion of management, it is more likely than
not that some portion or all of the deferred tax assets will not be realized.
Deferred tax assets and liabilities are adjusted for the effects of changes in
tax laws and rates on the date of enactment.

Prior to July 1, 1993, deferred income taxes were recorded under the deferral
method (APB 11) to reflect the tax consequences of timing differences between
the recording of income and expenses for financial statement purposes and income
tax purposes. Deferred income taxes were recorded at the tax rates in effect
when the differences arose.

Premises and equipment: Premises and equipment are carried at cost, net of
- -----------------------
accumulated depreciation. Depreciation is computed by the straight-line and
declining balance methods over the estimated useful lives of the assets.

Earnings per share: Earnings per share is calculated by dividing net income by
- -------------------
the weighted average number of common shares outstanding.

Reclassification: Certain amounts from the 1994 and 1993 financial statements
- -----------------
have been reclassified to conform with the 1995 presentation. These
reclassifications did not effect previously reported net income or stockholders'
equity.

The amortized cost and fair value of securities being held to maturity and
available for sale as of June 30, 1995 by contractual maturity are shown below.
Maturities may differ from contractual maturities in mortgage-backed securities
because the mortgages underlying the securities may be called or repaid without
any penalties. Therefore, these securities are not included in the maturity
categories in the following maturity summary. The equity and certain other
securities have also been excluded from the maturity table because they do not
have contractual maturities associated with debt securities.

Note 10. Accounting Change, Income Taxes and Retained Earnings

As explained in Note 1, the Company adopted FASB Statement No. 109, Accounting
for Income Taxes effective July 1, 1993. The cumulative effect of this change as
of June 30, 1993 has been reflected in the consolidated statement of income for
1994, and prior year financial statements have not been restated.

Under existing provisions of the Internal Revenue Code and similar sections of
the Iowa income tax law, the subsidiary bank is allowed a special bad debt
deduction which is based on a percentage of otherwise taxable income. If the
amounts that qualify as deductions for income tax purposes are used for purposes
other than to absorb bad debt losses, they will be subject to income taxes at
the then corporate rate.

The Company and its subsidiaries file consolidated federal income tax returns.
Income taxes are allocated to each entity based on each entity's income tax
liability as if it would have filed a separate return.

Income tax expense for the years ended June 30 is summarized as follows:

Retained earnings at June 30, 1995 and 1994 includes approximately $1,900,000
for which no deferred tax liability has been recognized. This amount represents
an allocation of income to bad-debt deductions for tax purposes only. Reduction
of the amount so allocated for purposes other than tax bad-debt losses or
adjustments arising from carryback of net operating losses would create income
for tax purposes only, which would be subject to the then current corporate
income tax rate. The unrecorded deferred income tax liability on this amount for
financial statement purposes was approximately $655,000 at June 30, 1995 and
1994.

Regulatory Capital Requirements  The Financial Institutions Reform, Recovery, 
- -------------------------------
and Enforcement Act of 1989 (FIRREA) and OTS regulations require institutions to
meet certain regulatory requirements. The regulations require minimum regulatory
tangible capital of 1.5% of total assets, a 3% core capital ratio and an 8% 
risk-based capital ratio. The Federal Deposit Insurance Corporation Improvement
Act of 1991 (FDICIA) contains provisions which require institutions to maintain
a core capital ratio of at least 4% to be considered adequately capitalized
unless its supervisory condition is such to allow it to maintain a 3% ratio. At
June 30, 1995, the Bank meets all regulatory capital requirements.

The following is a reconciliation of the Bank's capital in accordance with
generally accepted accounting principles (GAAP) to the three components of
regulatory capital calculated under the requirement of FIRREA at June 30, 1995:

</TABLE> 


There were no differences in capital and net income in this financial report as
compared to the quarterly report filed with the Office of Thrift Supervision
dated June 30, 1995.

Limitations on Dividends and Other Capital Distributions OTS regulations impose
limitations on dividends and other capital distributions by savings
institutions. Capital distributions include cash dividends, payments to
repurchase or otherwise acquire the savings association's shares, payments to
stockholders of another institution in a cash out merger, and other
distributions charged against capital. The rule establishes three tiers of
institutions. An institution such as the Bank that exceeds all fully phased-in
capital requirements before and after a proposed capital distribution ("Tier 1
Association") may, after prior notice but without the approval of the OTS, make
capital distributions during a calendar year up to the higher of (i) 100% of its
net income to date during the calendar year plus the amount that would reduce by
one-half its surplus capital at the beginning of the calendar year or (ii) 75%
of its net income over the most recent four-quarter period, subject to certain
limitations and restrictions as described in the regulations. Any additional
capital distributions would require prior regulatory approval. A savings
institution that does not meet its current regulatory capital requirement before
or after payment of a proposed capital distribution may not make any capital
distributions without the prior approval of the OTS. At June 30, 1995 the Bank
was considered a Tier 1 Association.

Note 12. Employee Benefits

The Company has a 401(k) retirement plan that covers substantially all employees
whereby employees may elect to defer a portion of their salary through
contribution to the plan. The employers' double participant contributions up to
3% of the employee's compensation. The employer may also contribute an
additional discretionary amount to be determined on an annual basis. The total
contributions to the plan were $142,848, $141,907 and $107,380 for the years
ended June 30, 1995, 1994 and 1993, respectively.

The Company has employment agreements with certain officers. The agreements
provide for a continuation of compensation for a period of three years for three
of the officers and one year for four of the officers. The agreements become
effective if the officers are terminated from employment subsequent to a change
in control of the Company.


Note 13. Financial Instruments With Off-Statement of Financial Condition Risk

The Company is a party to financial instruments with off-statement of financial
condition risk in the normal course of business to meet the financing needs of
its customers. These financial instruments consist primarily of loans sold with
recourse and commitments to extend credit. Those instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized in the statement of financial condition. The contract or notional
amounts of those instruments reflect the extent of involvement the banks have in
particular classes of financial instruments.

The Company uses the same credit policies in making commitments and conditional
obligations as it does for on-statement of financial condition instruments.

The Company requires collateral or other security to support financial
instruments with credit risk.

A summary of the contract amount of the Company's exposure to off-statement of
financial condition risk for commitments to extend credit as of June 30 are as
follows:

</TABLE> 

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

As of June 30, 1995, the Company has sold 51 loans with recourse with a
remaining principal balance of $605,047.

Subsequent to June 30, 1995, the Company purchased $15,000,000 in second
mortgage loans which was funded by the utilization of existing liquid assets and
an additional $5,000,000 in advances from the Federal Home Loan Bank of Des
Moines.

At June 30, 1995, the Company had no outstanding commitments to sell loans or
securities.

Note 14. Stock Options

The Company has a stock option plan for certain officers, directors and
employees. As of June 30, 1995 options to purchase 24,858 shares of common stock
at a price of $56 per share and 400 shares of common stock at a price of $19.25
per share are outstanding which are exercisable over a ten-year period expiring
in August, 2004. 1,000 shares remain available for future grants to the officers
and employees.

Note 16. Estimated Fair Values of Financial Instruments
FASB Statement No. 107, Disclosures about Fair Value of Financial Instruments,
requires disclosures of fair value information about financial instruments,
whether or not recognized in the statement of financial condition, for which it
is practicable to estimate that value. In cases where quoted market prices are
not available, fair values are based on estimates using present value or other
valuation techniques. Those techniques are significantly affected by the
assumptions used, including the discount rate and estimates of future cash
flows. In that regard, the derived fair value estimates cannot be substantiated
by comparison to independent markets and, in many cases, could not be realized
in immediate settlement of the instrument. Statement 107 excludes all
nonfinancial instruments from its disclosure requirements. Accordingly, the
aggregate fair value amounts presented do not represent the underlying value of
the Company.

The following methods and assumptions were used by the Company in estimating the
value of its financial instruments:

Cash: The carrying amount reported in the consolidated statement of financial
- ----
condition for cash approximates its fair value.

Securities available for sale and securities held to maturity: Fair values for
- -------------------------------------------------------------
securities available for sale and held to maturity securities are based on
quoted market prices, where available. If quoted market prices are not
available, fair values are based on quoted market prices of comparable
instruments.

Mortgage-backed securities: Fair values for mortgage-backed securities are based
- --------------------------
on quoted market prices.

Loans receivable and loans held for sale: The fair values of loans receivable
- ----------------------------------------
and loans held for sale are estimated using discounted cash flow analyses, using
interest rates currently being offered for loans receivable and loans held for
sale with similar terms to borrowers with similar credit quality.

Accrued interest receivable: The carrying amount of accrued interest receivable
- ---------------------------
approximates its fair value.

Deposits: The carrying amount reported in the statement of financial condition
- --------
for demand and savings deposits, which represents the amount payable on demand,
approximates their fair values. Fair values for fixed-rate and variable-rate
certificates of deposit are estimated using a discounted cash flow calculation
that applies interest rates currently being offered on certificates to a
schedule of aggregated expected maturities on time deposits.

Borrowed funds: The carrying value of borrowed funds approximates their fair
- --------------
value.

Accrued interest payable and advances from borrowers for taxes and insurance:
- ----------------------------------------------------------------------------
The carrying value of accrued interest payable and advances from borrowers for
taxes and insurance approximates their fair value.

Commitments to extend credit: The fair values of commitments are considered
- ----------------------------
equal to their notional values, based on the fees currently charged to enter
into similar agreements, taking into account the remaining terms of the
agreements and credit worthiness of the counterparties.

HERITAGE FINANCIAL, LTD. AND SUBSIDIARY



NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
- -----------------------------------------------------------------------------

Significant Accounting Policies
- -------------------------------

The consolidated financial statements for the nine month periods ended March 31,
1996 and 1995 are unaudited. In the opinion of the management of Heritage
Financial, Ltd. these financial statements reflect all adjustments, consisting
only of normal recurring accruals necessary to present fairly these consolidated
financial statements. The results of operations for the interim periods are not
necessarily indicative of results which may be expected for an entire year.
Certain information and footnote disclosure normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been omitted.

The consolidated condensed financial statements include the accounts of Heritage
Financial, Ltd (the Company) and its wholly owned subsidiary, Hawkeye Federal
Savings Bank of Boone (the Bank). All significant intercompany balances and
transactions have been eliminated in consolidation.

Reclassification of Securities
- ------------------------------

During 1995, Financial Accounting Standards Board Special Report- "A Guide to
Implementation of Statement No. 115 on Accounting for Certain Investments in
Debt and Equity Securities" allowed a reassessment of the appropriateness of the
classification of securities under certain circumstances. Held-to-maturity
securities with an amortized cost of $8,398,314 and a fair value of $8,275,842
were reclassified as available for-sale in December, 1995 in accordance with
guidance provided by the report. The reclassification was made at fair value and
the difference between the amortized cost and fair value on the date of transfer
was recognized as a decrease in stockholders' equity, net of the related
deferred tax effect.

Regulatory Capital Requirements
- -------------------------------

Pursuant to the Financial Institutions Reform, Recovery and Enforcement Act of
1989 ("FIRREA"), savings institutions must meet three separate minimum capital-
to-asset requirements. As of March 31, 1996, the Bank substantially exceeded all
current regulatory capital standards.

Earnings Per Share
- ------------------

Earnings per share is calculated using the weighted average number of shares of
common stock outstanding and the effect of dilutive stock options for the nine
month period ended March 31, 1996 and 1995. The weighted average number of
shares of common stock outstanding for the nine months ended March 31, 1996 and
1995 are 193,045 and 177,191, respectively.

Nonperforming Assets and Subsequent Event
- -----------------------------------------


The level of nonperforming assets increased from $46,000 at June 30, 1995 to $2
million at March 31, 1996, primarily due to the Bennett Funding loans of
approximately $1.8 million being placed on nonaccrual status. The Bennett
Funding loans are loans to the Bennett Funding Group and certain affiliates
which are collateralized by equipment leases. Approximately 10,000 investors and
200 financial institutions nationwide had similar investments or lending
relationships with Bennett. Bennett filed for Chapter 11 bankruptcy protection
on March 29, 1996 after the principals of the company were charged with various
criminal offenses relating to the leasing transactions. Upon the filing of the
Bennett bankruptcy case, Hawkeye's Bennett Funding Loan became nonperforming.

HERITAGE FINANCIAL, LTD. AND SUBSIDIARY



NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
- -----------------------------------------------------------------------------

In evaluating the March 31, 1996 allowance for loan losses, Bank management 
reviewed the Bank's files relating to this loan.  Based on this review, and the 
limited information available at that time, management did not believe that an 
adjustment to the allowance for loan losses was warranted at March 31, 1996.

Heritage management is closely following the developments at the Bennett Funding
Group and has retained legal counsel to guide it through the Bennett bankruptcy 
proceedings.  The reports from the bankruptcy trustee and legal counsel allege 
that significant fraudulent activity took place at Bennett Funding.  Based on 
this and other pertinent information, at June 30, 1996.  Heritage management 
decided to establish a specific reserve for the entire balance via a charge to 
the provision for loan losses.  This had the affect of reducing fourth quarter 
earnings by $1.8 million less the tax effect of $600,000 for a net effect of 
$2.7 million.

Subsequent Event - Merger
- -------------------------

On May 16, 1996, the Company entered into a "Reorganization and Merger
Agreement" (the Agreement) with Commercial Federal Corporation (Commercial
Federal) of Omaha, Nebraska. The Agreement calls for Company stockholders to
receive cash and stock of approximately $116.61 per share (subject to
adjustment, as described below), the actual amount to be determined based upon
the price of Commercial Federal's stock prior to closing (as defined in the
Agreement). The payment to Company stockholders will, in the aggregate, be
comprised of approximately 80% of Commercial Federal stock and 20% cash.

As more fully described in the Agreement, the cash consideration to be received
by Heritage stockholders may be increased depending on the extent to which the
Bennett Funding Loans previously described recover value prior to or for a
certain period of time following the merger.

The Agreement is subject to regulatory and shareholder approval and is
cancelable only if certain conditions are met, as specified in the Agreement.
The Company expects the transaction to close prior to October 31, 1996.

                      REORGANIZATION AND MERGER AGREEMENT

================================================================================


     THIS REORGANIZATION AND MERGER AGREEMENT ("Agreement") is dated as of May
16, 1996, by and among COMMERCIAL FEDERAL CORPORATION, a Nebraska corporation
("Commercial"), and COMMERCIAL FEDERAL BANK, A FEDERAL SAVINGS BANK, a Federally
chartered savings bank and wholly-owned subsidiary of Commercial ("Bank"); and
Heritage Financial, Ltd. an Iowa corporation ("Company"), and  Hawkeye Federal
Savings Bank, a Federally chartered savings bank and wholly-owned subsidiary of
Company ("Hawkeye").

     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 Boone, Iowa, owns all of the issued and
outstanding capital stock of Hawkeye, with principal offices in Boone, Iowa;

     WHEREAS, Commercial and Company desire to combine their respective holding
companies through a tax-free 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 Hawkeye 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;

     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 Hawkeye with and into the 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; and

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

                                      A-5
<PAGE>
 
respective stockholders and have approved this 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:


                                   ARTICLE I
                         THE MERGER AND RELATED MATTERS

     1.1  Merger: Surviving Institution.  Subject to the terms and conditions of
          -----------------------------                                         
this Agreement, and pursuant to the provisions of the Nebraska Business
Corporation Act ("NBCA"), the Iowa Business Corporation Act ("IBCA"), Home
Owners Loan Act, as amended ("HOLA"), and the rules and regulations promulgated
thereunder (the "Thrift Regulations"), (a) at the Acquisition Merger Effective
Time (as hereinafter defined), the Company shall be merged with and into
Commercial pursuant to the terms and conditions set forth herein and in the Plan
of Merger set forth as Exhibit 1.1(a) attached hereto (the "Acquisition Plan of
Merger"), and the separate corporate existence of the Company shall cease, and
(b) thereafter, at the Bank Merger Effective Time (as hereinafter defined)
Hawkeye shall be merged with and into the Bank pursuant to the terms and
conditions set forth herein and in the Plan of Merger set forth in Exhibit
1.1(c) (the "Bank Plan of Merger").  The Acquisition Merger shall have the
effects specified in the NBCA and the IBCA, Section 1.4(e) hereof and the
Acquisition Plan of Merger.  Upon the consummation of the Acquisition Merger,
the separate corporate existence of the Company shall cease and Commercial shall
continue as the surviving corporation (sometimes referred to herein as the
"Surviving Corporation").  Upon consummation of the Bank Merger, the separate
existence of Hawkeye shall cease and the Bank shall continue as the surviving
institution of the Bank Merger.  The name of the Bank, as the surviving
institution of the Bank Merger, shall remain "Commercial Federal Bank, a Federal
Savings Bank".  From and after the Bank Merger Effective Time, the Bank, as the
surviving institution of the Bank Merger, shall possess all of the properties
and rights and be subject to all of the liabilities and obligations of the Bank
and Hawkeye, all as more fully described in the Thrift Regulations, Section 1.13
hereof and the Bank Plan of Merger.  Commercial may at any time change the

in no event later than thirty (30) days following such satisfaction or waiver
(unless otherwise agreed by the parties hereto) Commercial will file, or cause

Stock arrived at by dividing 107.43 by the Average NYSE Closing Price.

          (E) In the event the Average NYSE Closing Price is equal to or greater
than $47.50 but equal to or less than $50.00, then the aggregate per share value
of the Merger Consideration shall equal (i) 2.262 shares of Commercial Common
Stock in Stock Consideration and (ii) $24.47 in Cash Consideration.

          (F)  In the event the Average NYSE Closing Price is greater than

hereunder shall in each case be reduced on a pro rata basis in accordance with
the provisions of Section 1.15 of this Agreement.

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

period commencing on the date hereof and ending with the Acquisition Merger
Effective Time, additional shares of common stock or other securities for their
stock by way of a stock split, stock dividend, reclassification, combination of
shares or similar corporate rearrangement ("Stock Adjustment"), then the amount
of Commercial common stock to be exchanged at the Acquisition Merger Effective
Time for Company common stock shall be proportionately adjusted to take into
account such Stock Adjustment.  In addition, the Average NYSE Closing Price, as
defined below, shall be proportionately adjusted to compensate for any such
Stock Adjustment.

          (b) The term "NYSE Closing Price" shall mean the closing price per
share (carried to four decimal places and rounded down) of the Commercial Common
Stock on the New York Stock Exchange.  The term "Average NYSE Closing Price"

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.

and authority, of a public as well as of a private nature, of each of Commercial
and Company, and all obligations belonging or due to each of Commercial and
Company, all of which are vested in the Surviving Corporation without further

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

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

              (iii) All the rights of creditors of each of Company and
Commercial shall be preserved unimpaired, and all liens upon the property of
Company and Commercial shall be preserved unimpaired, on only the property

     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.  Immediately prior to the
Acquisition Merger Effective Time, Commercial shall make available for exchange
or conversion, by transferring to an exchange agent appointed by Commercial (the
"Exchange Agent") for the benefit of the holders of Company common stock:   (i)
such number of shares of Company common stock as shall be issuable in connection
with the payment of the aggregate Stock Consideration, and (ii) such funds as
may be payable in connection with the aggregate Cash Consideration and as may be
payable in lieu of fractional shares of Commercial Common Stock.

          (b) After the Acquisition Merger Effective Time, holders of
certificates theretofore evidencing outstanding shares of Company common stock
(other than as provided in Section

                                     A-10
<PAGE>
 
1.3(a)(iii)), upon surrender of such certificates to the Exchange Agent, shall
be entitled to receive certificates representing the number of 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, cash payable for the Cash Consideration, and
cash payments in lieu of fractional shares as provided in Section 1.14 hereof.
As soon as practicable after the Acquisition Merger Effective Time, the Exchange
Agent will send to each Company shareholder of record at the Acquisition Merger
Effective Time whose Company common stock shall have been converted into
Commercial Common Stock a letter of transmittal and instructions for
surrendering to the Exchange Agent outstanding certificates formerly evidencing
Company common stock in exchange for new certificates for Commercial Common
Stock and for cash payable for the Cash Consideration.  Upon surrender, each
certificate evidencing Company common stock shall be cancelled.

          (c) Until surrendered as provided in this Section 1.5 hereof, each
outstanding certificate which, prior to the Acquisition Merger Effective Time,
represented Company common stock (other than shares cancelled at the Acquisition
Merger Effective Time pursuant to Section 1.3(a)(ii) hereof) will be deemed for
all purposes to evidence ownership of the number of shares of Commercial Common
Stock into which the shares of Company common stock formerly represented thereby
were converted and the right to receive cash payable for the Cash Consideration.
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 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 for the Cash Consideration and in lieu of fractional shares pursuant
to Section 1.14 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 the Cash
Consideration and in lieu of any fractional share issued and paid upon the
surrender for exchange of Company common stock as provided herein shall be
deemed to have been issued in full satisfaction of all rights pertaining to such
shares of Company common stock.

                                     A-11
<PAGE>
 
          (e) If any new certificate for Commercial Common Stock is to be issued
in the name other than that in which the certificate surrendered in exchange
thereof is registered, it shall be a condition of the issuance therefor that the
certificate surrendered in exchange shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such transfer pay to the
Exchange Agent any transfer or other taxes required by reason of the issuance of
a new certificate for shares of Commercial Common Stock in any name other than
that of the registered holder of the certificate surrendered, or establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
payable.

          (f) In the event any certificate for Company common stock shall have
been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for
such lost, stolen or destroyed certificate, upon the making of an affidavit of
that fact by the holder thereof, such shares of Commercial Common Stock and cash
for the Cash Consideration and in lieu of fractional shares, if any, as may be
required pursuant hereto; provided, however, that Commercial may, in its
reasonable 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  Dissenting Shares.  Any shares of Company common stock held by a
          -----------------                                               
holder who dissents from the Merger and becomes entitled to obtain payment for
the value of such shares of Company common stock pursuant to the applicable
provisions of the IBCA shall be herein called "Dissenting Shares."  Any
Dissenting Shares shall not, after the Acquisition Merger Effective Time, be
entitled to vote for any purpose or receive any dividends or other distributions
and shall not be entitled to receive the Merger Consideration; provided,
however, that shares of Company common stock held by a dissenting stockholder
who subsequently withdraws a demand for payment, fails to comply fully with the
requirements of the IBCA, or otherwise fails to establish the right of such
stockholder to be paid the value of such stockholders' shares under the IBCA
shall be deemed to be converted into the right to receive the Merger
Consideration pursuant to the terms and conditions referred to above.

     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 at least a majority of the issued and
outstanding shares of Company common stock shall be required for such approval.

                                     A-12

     1.8  Company Stock Options.  Each holder of an option (a "Company Stock
          ---------------------                                             
Option") which is an outstanding option under the Company's 1994 Stock Option
Plan (the "Company Option Plan") shall, in cancellation of such option (such
cancellation to be reflected in a written agreement), receive from Company,
immediately prior to the Acquisition Merger Effective Time, per share of Company
common stock subject to such option, a cash payment in the amount of the per
share value of the Merger Consideration, less the exercise price of such option,
net of any cash which must be withheld under federal and state income tax
requirements.  Immediately thereafter, Company shall cancel each such option.
At least ten (10) business days prior to the Closing (as defined in Section 1.11
hereof), and then immediately prior to the Closing, Company shall afford
Commercial the right to review the cash amounts proposed to be paid to optionees
hereunder.

     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, as amended (the "1933 Act") and the Securities Exchange Act of 1934, as
amended (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' 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 provide to the Company and 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

                                     A-13
<PAGE>
 
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 its best
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 by the Company or its representatives for the purpose of inclusion in
the Prospectus/Proxy Statement.  The Company shall have the right to review and
comment on the Prospectus/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 the Company with copies of all such documents.  Prior
to the Acquisition Merger Effective Time or the termination of this Agreement,
each party  shall consult with the other  with respect to any material (other
than the Prospectus/Proxy Statement) that might constitute a "prospectus"
relating to the Merger within the meaning of the 1933 Act.

          (e) The Company shall consult with Commercial in order to determine
whether any directors, officers or shareholders of the  Company may be deemed to
be "affiliates" of Company ("affiliated persons") within the meaning of Rule 145
of the SEC promulgated under the 1933 Act.  All shares of Commercial Common
Stock issued to such Company affiliated persons in connection with the Merger
shall bear a legend upon the face thereof stating that transfer of the
securities is or may be restricted by the provisions of the 1933 Act, and notice
shall be given to Commercial's transfer agent of such restriction, provided that
such legend shall be removed by delivery of a substitute certificate without
such legend if such Company affiliated person shall have delivered to Commercial
a copy of a letter from the staff of the SEC or an opinion of counsel, in form
and substance satisfactory to Commercial, to the effect that such legend is not
required for purposes of the 1933 Act, and, in any event, at any time after the
expiration of 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

                                     A-14
<PAGE>
 
such Commercial Common Stock bear such legend, no transfer of such Commercial
Common Stock shall be allowed unless and until the transfer agent is provided
with such information as may reasonably be requested by counsel for Commercial
to assure that such transfer will not violate applicable provisions of the 1933
Act, or rules, regulations or policies of the SEC.

     1.10 Cooperation; Regulatory Approvals.  The parties shall cooperate and
          ---------------------------------

("FTC"), Department of Justice ("DOJ"), SEC, applicable Secretary of State,
other regulatory authorities, holders of the voting shares of common stock of

shareholders of the Company, and (ii) all relevant conditions of this Agreement
have been satisfied or waived, a closing (the "Closing") shall take place as
promptly as practicable thereafter at the principal office of Commercial at
which the parties hereto will exchange certificates, opinions, letters and other

hereof.  Such Closing will take place as soon as practicable as agreed by the
parties, provided, however, that the Closing shall be no more than thirty (30)
         --------  -------                                                    
days after the satisfaction or waiver of all conditions and/or obligations
contained in Article V of this Agreement.

     1.12 Closing of Transfer Books.  At the Acquisition Merger Effective Time,
          -------------------------

shares of Company common stock shall thereafter be made on such books.

     1.13 Bank Merger.
          ----------- 

          (a) At the Bank Merger Effective Time, each share of Hawkeye Common
Stock issued and outstanding immediately prior thereto shall, by virtue of the
Bank Merger, be cancelled.  No new shares of the capital stock or other
securities or obligations of the Bank shall be issued or be deemed issued with
respect to or in exchange for such cancelled shares, and such cancelled shares
of Hawkeye Common Stock shall not be converted into any shares or other
securities or obligations of the Bank.

<PAGE>
 
          (b) The charter and bylaws of the Bank, as in effect immediately prior
to the Bank Merger Effective Time, shall be the charter and bylaws of the Bank,
as the surviving institution of the Bank Merger, and may thereafter be amended
in accordance with applicable law.

          (c) The directors and officers of the Bank immediately prior to the
Bank Merger Effective Time shall be the directors and officers of the Bank, as
the surviving institution of the Bank Merger, and shall continue in office until
their successors are duly elected or otherwise duly selected.

          (d) The liquidation account established by Hawkeye pursuant to the
plan of conversion adopted in connection with its conversion from mutual to
stock form shall continue to be maintained by the Bank after the Bank Merger
Effective Time for the benefit of those persons and entities who were savings
account holders of Hawkeye on the eligibility record date for such conversion
and who continue from time to time to have rights therein.  If required by the
rules and regulations of the OTS, the Bank shall amend its charter to
specifically provide for the continuation of the liquidation account established
by Hawkeye.

     1.14 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 NYSE Closing
Price.  For the purposes of determining any such fractional share interests, all
shares of Commercial Common Stock received by a holder of the Company common
stock shall be combined so as to calculate the maximum number of whole shares of
Commercial Common Stock issuable to such Company shareholder in the Acquisition
Merger.

and, as of their respective date or the date as amended, did not contain any

governmental or court orders, or rules or regulations currently in effect,
including but not limited to ERISA and the Code, applicable to such Employee
Plans or Benefit Arrangements.  Except as disclosed in Section 2.13 of Schedule
I, 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 or results of operations 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

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

other loans of the Company or any Company Subsidiary (either individually or in
the aggregate with other loans and investments).

     2.22 Derivatives Contracts.  Neither the Company nor any of its

     4.3  No Solicitation.  The Company will not authorize any officer,
          ---------------                                              
director, employee, investment banker, financial consultant, attorney,
accountant or other representative of Company or any Company Subsidiary,
directly or indirectly, to initiate contact with any person or entity in an
effort to solicit, initiate or encourage any "Takeover Proposal" (as such term
is defined below).  Except as the fiduciary duties of the Company Board of
Directors may otherwise require (as determined in consultation with legal
counsel), the Company will not authorize any officer, director, employee,
investment banker, financial consultant, attorney, accountant or other
representative of the Company or any Company Subsidiary, directly or indirectly,
(A) to cooperate with, or furnish or cause to be furnished any non-public
information concerning its business, properties or assets to, any person or
entity in connection with any Takeover Proposal; (B) to negotiate any Takeover
Proposal with any person or entity; or (C) to enter into any agreement, letter
of intent or agreement in principle as to any Takeover Proposal.  The Company
will promptly give written notice to Commercial upon becoming aware of any

duties of the Company's Board of Directors may otherwise require), the identity
of the persons submitting the Takeover Proposal, a copy of any written inquiry
or other communication, the terms of

                                     A-38
<PAGE>
 
any Takeover Proposal, any information requested or discussions sought to be
initiated and the status of any requests, negotiations or expressions of
interest.  As used in this Agreement with respect to the Company, "Takeover
Proposal" shall mean any bona fide proposal, other than as contemplated by this
Agreement, for a merger or other business combination involving the Company or
Hawkeye or for the acquisition of a ten percent (10%) or greater equity interest
in Company or Hawkeye, or for the acquisition of a substantial portion of the
assets of Company or Hawkeye (other than loans or securities sold in the
ordinary course).

     4.4  Shareholder Approvals.  The Company shall call the meeting of its
          ---------------------                                            
shareholders to be held for the purpose of voting upon the Acquisition Merger
and related matters, as referred to in Section 1.7 hereof, as soon as
practicable, but in no event later than sixty (60) days after the Registration
Statement becomes effective under the 1933 Act.  In connection with such
meeting, the Company Board of Directors shall recommend approval of the Merger,
except as the fiduciary duties of the Company's Board of Directors may otherwise
require.  The Company shall use its best efforts to solicit from its
shareholders proxies in favor of approval and to take all other action necessary
to secure a vote of the holders of the shares of Company common stock in favor
of the Merger, except as the fiduciary duties of the Boards of Directors may
otherwise require.

     4.5  Filing of Holding Company and Merger Applications.  Commercial shall
          -------------------------------------------------                   
use its best efforts promptly to prepare, submit and file within seventy-five

563.22(a) for the Bank Merger and any other applications required to be filed in
connection with the transactions contemplated hereby.

     4.6  Consents.  The Company and Hawkeye will use their best efforts to
          --------                                                         
obtain the consent or approval of each person whose consent or approval shall be
required of them in order to permit Company or Hawkeye, as the case may be, to
consummate the Acquisition Merger and the Bank Merger.

     4.7  Certain Actions.   Neither Commercial nor the Company (including the
          ---------------                                                     
Company Subsidiaries) shall take any action which would materially impede or
delay consummation of the Merger, or prevent the transactions contemplated
hereby from qualifying as a reorganization within the meaning of Section 368 of
the Code.

     4.8  Publicity.  Between the date of this Agreement and the Acquisition
          ---------                                                         
Merger Effective Time, neither Commercial, Company or any of their subsidiaries
shall, without the prior approval of the other, issue or make, or permit any of
its directors, employees,

                                     A-39
<PAGE>
 
officers or agents to issue or make, any press release, disclosure or statement
to the press or any third party with respect to the Merger or the transactions
contemplated hereto, except as required by law.  The parties shall cooperate
when issuing or making any press release, disclosure or statement with respect
to Merger or the transactions contemplated hereby, except as required by law.

     4.9  Cooperation Generally.  Between the date of this Agreement and the
          ---------------------                                             
Acquisition Merger Effective Time, subject to the provisions of this Agreement,
Commercial, the Company and their respective subsidiaries shall use their
respective best efforts, and take all actions necessary or appropriate, to
consummate the Merger and the other transactions contemplated by this Agreement
at the earliest practicable date.  Commercial and the Bank, on one hand, and the
Company and the Company Subsidiaries, on the other hand, agree not to knowingly
take any action that would (i) adversely affect their respective ability to
obtain the Governmental Approvals or (ii) adversely affect their respective
ability to perform their obligations under this Agreement.

     4.10 Additional Financial Statements and Reports.  As soon as reasonably
          -------------------------------------------                        
practicable after they become publicly available, the Company shall furnish to
Commercial and Commercial shall furnish to the Company, respectively, its
balance sheet and related statements of operations (and, in the case of
Commercial, cash flows and stockholders' equity) for all periods prior to the
Closing.  Such financial statements will be prepared in conformity with
generally accepted accounting principles applied on a consistent basis and
fairly present the financial condition and results of operations (and in the
case of Commercial, cash flows) of the Company or Commercial, as the case may be
(subject, in the case of unaudited financial statements, to (a) normal year-end
audit adjustments, (b) any other adjustments described therein and (c) the
absence of notes from which, if presented, would not differ materially from
those included in its most recent audited consolidated balance sheet), and all
of such financial statements will be prepared in conformity with, in the case of
Commercial, the requirements of Form 10-Q or Form 10-K, as the case may be,
under the 1934 Act, and in the case of Commercial or the Company, such other
requirements under the 1933 Act or 1934 Act as may be applicable.

     4.11 Stock Listing.  Commercial agrees to use its best efforts to cause to
          -------------                                                        
be listed on the New York Stock Exchange, subject to official notice of
issuance, the shares of Commercial Common Stock to be issued in the Merger.

     4.12 Allowance for Loan and Real Estate Owned Losses.  At the request of
          -----------------------------------------------                    
Commercial and in an amount specified by Commercial, prior to the Acquisition
Merger Effective Time, the Company and Hawkeye shall establish such additional
provisions for loan and real estate owned losses as may be necessary in the sole
determination of Commercial to conform the Company's and Hawkeye's

                                     A-40
<PAGE>
 
loan and real estate owned allowance practices and methods to those of
Commercial and the Bank (as such practices and methods are to be applied to
Company and Hawkeye from and after the Acquisition Merger Effective Time);
provided, however, that Company and Hawkeye shall not be required to take such
action until: (i) the Company and Hawkeye provide to Commercial a written
statement dated the date of Closing certified by the Chairman of the Board, the
President and the Chief Financial Officer of the Company and Hawkeye, that the
conditions in Sections 5.1 and 5.2 to be satisfied by the Company or Hawkeye or
both of them have been satisfied by either or both of them or, alternatively,
setting forth in detail the circumstances that have prevented such conditions
from being satisfied (the "Reliance Certificate"), and Commercial and Bank
provide to Company and Hawkeye a Reliance Certificate relating to the
satisfaction of the conditions in Sections 5.1 and 5.3; and (ii) Commercial and
the Bank, after reviewing the Reliance Certificate, provide the Company and
Hawkeye 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 Hawkeye have established such additional provisions for loan and real estate
losses as requested by Commercial pursuant to this Section 4.12.  No additional
provision for loan and real estate owned losses taken by Hawkeye pursuant to
this Section 4.12 shall be deemed in and of itself to be a breach or violation
of any representation, warranty, covenant, condition or other provision of this
Agreement.

     4.13 D&O Indemnification and Insurance.   For a period of three (3) years
          ---------------------------------                                   
following the Acquisition Merger Effective Time, Commercial shall indemnify the
employees, agents, directors or officers of the Company and the Company
Subsidiaries to the extent they are indemnified under the Company's Articles of
Incorporation and Bylaws in the form in effect at the date of this Agreement or
arising by operation of law.  Commercial shall cause the directors and officers
listed in Schedule 4.13 to be covered under individual directors' and officers'
liability insurance policies, which coverage is available in the form of tail
coverage under the Company's existing directors' and officers' liability policy
for the duration of any applicable statute of limitations.  The amount of the
coverage obtained for each director and officer shall be the amount available
under the terms of such individual policies when $3,500 is expended per person.
In no event shall Commercial be required to expend in the aggregate in excess of
$55,000 to obtain such coverage.

     4.14  Tax Treatment.  Commercial and Company shall use their best efforts
           -------------                                                      
to cause the Merger to qualify as a reorganization under Section 368(a)(1) of
the Code.  The Company agrees to consent to the form of representation letter
provided by Deloitte & Touche LLP for purposes of issuing its federal tax
opinion pursuant to Section 5.1(e) of this Agreement no later than thirty (30)
days prior to the Closing.

     4.15 Update Disclosure.  From and after the date hereof until the
          -----------------                                           
Acquisition Merger Effective Time, the Company shall promptly, but not less
frequently than monthly, update Schedule I hereto by notice to Commercial to
reflect any matters which have occurred from and after the date hereof which, if
existing on the date hereof, would have been required to be described therein
and which, in the case of all such updates other than the last such update prior
to the Acquisition Merger Effective Time, reflect a material change from the
information provided in Schedule I as of the date hereof; provided, however,
that no such update shall affect the conditions to the obligation of Company and
Hawkeye to consummate the transactions contemplated hereby, and any and all
changes reflected in any such update shall be considered in determining whether
such conditions have been satisfied.

     4.16 Cash Consideration.  Commercial will have sufficient cash on hand to
          ------------------                                                  
pay the Cash Consideration as of the Acquisition Merger Effective Time.

               CONDITIONS OF THE MERGER; TERMINATION OF AGREEMENT

     5.1  General Conditions.  The obligations of Commercial, the Bank, the
          ------------------                                               
Company and Hawkeye to effect the Acquisition Merger and the Bank Merger shall
be subject to the following conditions:

          (a) Stockholder Approval.  The holders of the outstanding shares of
              --------------------                                           
Company common stock shall have approved this Agreement and the Acquisition
Merger as specified in Section 1.7 hereof or as otherwise required by applicable
law.

          (b) No Proceedings.  No order, decree or injunction shall have been
              --------------                                                 
entered and remain in force restraining or prohibiting the Merger in any legal,
administrative, arbitration, investigatory or other proceedings (collectively,
"Proceedings").

          (c) Government Approvals.  To the extent required by applicable law or
              --------------------                                              
regulation, all approvals of or filings with any governmental authority
(collectively, "Governmental Approvals"), including without limitation those of
the OTS, the FDIC, the Federal Trade Commission, DOJ, the SEC, and any state

          (d) Registration Statement.  The Registration Statement shall have
              ----------------------                                        
been declared effective and shall not be subject to a stop order of the SEC and,
if the offer and sale of Commercial's common stock in the Merger pursuant to
this Agreement is subject to

                                     A-42
<PAGE>
 
the Blue Sky laws of any state, shall not be subject to a stop order of any
state securities commissioner.

          (e) Federal Tax Opinion.  Receipt of either an opinion of Deloitte &
              -------------------                                             
Touche LLP, or other tax advisor reasonably acceptable to Commercial and the
Company, or a private letter ruling from the IRS, in form and content reasonably
satisfactory to Commercial and the Company, and upon which Company shareholders
may rely to the effect that for federal income tax purposes:

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

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

     .    No gain or loss should be recognized by Company upon the distribution
          of the Commercial Common Stock to the Company shareholders, by reason
          of the application of Code Section 361(c)(1).

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

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

     .    The holding period of the property acquired by Commercial from Company
          should include the holding period of such property in the hands of
          Company immediately prior to the Merger, by reason of the application
          of Section 1223(2) of the Code.

     .    The gain, if any, to be realized by a Company shareholder who receives
          Commercial stock and cash in exchange for Company stock will be
          recognized, but not in excess of the amount of cash received.  If the
          exchange has the effect of the distribution of a dividend (determined
          with application of Code Section 318(a)), then the amount of gain
          recognized that is not in excess of each shareholder's ratable share
          of undistributed earnings and

                                     A-43
<PAGE>
 
          profits will be treated as a dividend.  The determination of whether
          the exchange has the effect of the distribution of a dividend will be
          made on a shareholder-by-shareholder basis.  No loss will be
          recognized on the exchange.

     .    Where cash is received by a dissenting shareholder of the Company,
          such cash will be treated as received by the dissenting shareholder as
          a distribution in redemption of the shareholder's Company common
          stock, subject to the provisions and limitations of Section 302.

     .    The basis of the Commercial Common Stock (including fractional share
          interests a Company shareholder would otherwise be entitled to
          receive) received by a Company shareholder who exchanges Company
          common stock for Commercial Common Stock and cash will be the same as
          the basis of the Company common stock surrendered in the Merger,
          decreased by the amount of cash received, and increased by the amount
          of cash received that is treated as a dividend (if any), and by the
          amount of gain recognized on the exchange (not including any portion
          of that gain that was treated as a dividend).

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

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

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

     .    Cash received by a shareholder of Company otherwise entitled to
          receive a fractional share of Commercial

                                     A-44
<PAGE>
 
          Common Stock in exchange for his Company stock should be treated as if
          the fractional shares were distributed as part of the Merger and then
          were redeemed by Commercial.  These cash payments should be treated as
          having been received as distributions in full payment in exchange for
          the stock redeemed as provided in Code Section 302(a).  This receipt
          of cash should result in gain or loss measured by the difference
          between the basis of such fractional share interest and the cash
          received.  Such gain or loss should be capital gain or loss to the
          former Company shareholder, provided the Company stock was a capital
          asset in such former shareholder's hands and as such, will be subject
          to the provisions and limitations of Subchapter P of Chapter 1 (Rev.
          Rul. 66-365 and Rev. Rul. 77-41).

Closing covering the matters to be set forth in Exhibit 5.2(a).

          (b) Required Consents.  The Company and Hawkeye shall have obtained

all necessary third party consents or approvals in connection with the Merger,
the absence of which would materially and adversely affect Company and the
Company Subsidiaries, taken as a whole; in this connection, the Company and
Hawkeye shall obtain consents from all lessors to their respective real estate
and other leases that may be required for consummation of the Merger.

          (c) Company Accountants' Letter.   Commercial shall have received from
              ---------------------------                                       
McGladrey & Pullen, LLP, letters dated the date of mailing the Prospectus/Proxy
Statement and the date of the Closing to the effect that: (i) with respect to
the Company they are independent accountants within the meaning of the 1933 Act
and 1934 Act and the applicable rules and regulations thereunder, (ii) it is
their opinion that the audited financial statements of the Company included in
the Prospectus/Proxy Statement comply as to form in all material respects with
the applicable accounting requirements of the 1933 Act and 1934 Act and the
applicable published accounting rules and regulations thereunder, (iii) on the
basis of such procedures as are set forth therein but without performing an
examination in accordance with generally accepted auditing standards nothing has
come to their attention which would cause them to believe that (A) any unaudited
interim financial statements appearing in the Prospectus/Proxy Statement do not
comply as to form in all material respects with the applicable accounting

                                     A-45
<PAGE>
 
requirements of the 1933 Act and 1934 Act and the published rules and
regulations thereunder; (B) said financial statements are not stated on a basis
substantially consistent with that of the audited financial statements; (C) (1)
at the date of the latest available consolidated financial statements of the
Company and at a specific date not more than five (5) business days prior to the
date of each such letter there has been, except as specified in such letter, any
increase in the outstanding capital stock, or indebtedness for borrowed money of
the Company (other than deposits and Federal Home Loan Bank advances with a

thereof as compared with amounts shown in the latest statement of financial
condition included in the Prospectus/Proxy Statement, or (2) for the period from
the date of the latest audited financial statements of the Company included in
the Prospectus/Proxy Statement to a specific date not more than five (5)
business days prior to the date of each such letter, there were, except as
specified in such letter, any decreases, as compared with the corresponding
period in the preceding year, in consolidated net income for Company or any
increase, as compared with the corresponding period in the preceding year, in
the provision for loan losses for Company, (iv) they have performed certain
specific procedures as a result of which they determined that certain
information of an accounting, financial or statistical nature included in the
Prospectus/Proxy Statement and requested by Commercial and agreed upon by such
accountants, which is expressed in dollars (or percentages obtained from such
dollar amounts) and obtained from accounting records which are subject to the
internal controls of the Company's accounting system or which has been derived
directly from such accounting records by analysis or computation is in agreement
with such records or computations made therefrom (excluding any questions of
legal interpretation), and (v) on the basis of such procedures as are set forth
in such letter, nothing came to their attention with respect to the Company
which would cause them to believe that the pro forma financial statements had
not been properly compiled on the pro forma basis described therein.

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

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

adverse change shall not include (i) any change attributable to or resulting
from any change in law, regulation or generally accepted accounting principles
or regulatory accounting principles, including, but not limited to, changes
resulting from amendments to or modifications of any law, rule or regulation
relating to the bad debt reserve of or deduction taken by thrift institutions or
any special insurance premium assessment by the FDIC on SAIF-insured deposits
which impairs the Company and other comparably sized and otherwise comparable
thrift institutions in a substantially similar manner, (ii) the effects of any
change attributable to or resulting

                                     A-46
<PAGE>
 
from changes in economic conditions applicable to depository institutions
generally or in general levels of interest rates affecting the Company and other
comparably sized and otherwise comparable thrift institutions to a similar
extent and in a similar manner, and (iii) any change in circumstances regarding

which renders impossible the satisfaction in any material respect one or more of
the conditions to the obligations of Commercial and the Bank to effect the
Merger set forth in Sections 5.1 and 5.2 and noncompliance is not waived by
Commercial, provided, however, that the right to terminate under this Section

as advised by special counsel, the Board of Directors of the Company determines
that such termination is required in connection with entering into an agreement
with a third party to engage in an Acquisition Transaction (as defined in

of its intention to terminate this Agreement and that the Company's ability to
terminate this Agreement pursuant to this paragraph is conditioned upon the
prior payment by the Company of the amounts owed by it to Commercial pursuant to
Section 6.2(b).

     For purposes of this Section 5.4, "Average NYSE Closing Price" shall have
the meaning specified in Section 1.3(b) and "Determination Period" shall have

     6.1  Termination; Lack of Survival of Representations and Warranties.  In
          ---------------------------------------------------------------     
the event of the termination and abandonment of this Agreement pursuant to
Section 5.4 of this Agreement, this Agreement shall become void and have no
effect, except that (i) the provisions of Sections 2.7 and 3.7 (Brokers and
Finders), 4.8 (Publicity), 6.2 (Expenses) and 8.2 (Confidentiality) of this
Agreement shall survive any such termination and abandonment, and (ii) a
termination pursuant to Sections 5.4(c) or 5.4(d) of this Agreement shall not
relieve the breaching party from liability for an uncured intentional and
willful breach of a representation, warranty, covenant, or agreement giving rise
to such termination.

     The representations, warranties and agreements of the parties set forth in
this Agreement shall not survive the Acquisition Merger Effective Time, and
shall be terminated and extinguished at the Acquisition Merger Effective Time,
and from and after the Acquisition Merger Effective Time none of the parties
hereto shall have any liability to the other on account of any breach or failure
of any of those representations, warranties and agreement; provided, however,
                                                           --------  -------

     (b) Notwithstanding any provision in this Agreement to the contrary, in
order to induce Commercial and the Bank to enter into this Agreement and as a
means of compensating Commercial and the Bank for the substantial direct and
indirect monetary and other costs incurred and to be incurred in connection with
this Agreement and the transactions contemplated hereby, the Company and Hawkeye
agree that if this Agreement is terminated in accordance with Section 5.4 (other
than if terminated by the Company pursuant to Section 5.4(d) hereof as a result
of Commercial's or the Bank's noncompliance with the conditions set forth in
Section 5.3(b) hereof) and prior to such termination a Termination Event, as
defined in paragraph (c) of this Section 6.2, shall have occurred, the Company
or Hawkeye will upon demand pay to Commercial or the Bank in immediately
available funds $1,000,000.

     (c) For purposes of this Agreement, a Termination Event shall mean either
of the following:

     (i) The Company or any Company Subsidiary, without having received
Commercial's prior written consent, shall have entered into an agreement to
engage in an Acquisition Transaction (as defined below) with any person (the
term "person" for purposes of this Agreement having the meaning assigned thereto
in Sections 3(a)((9) and 13(d)(3) of the Securities Exchange Act of 1934, and
the rules and regulations thereunder) other than Commercial or any affiliate of
Commercial (the term "affiliate" for purposes of this Agreement having the
meaning assigned thereto in Rule 405 under the 1933 Act) or the Board of
Directors of the Company shall have recommended that the shareholders of the
Company approve or accept any Acquisition Transaction with any person other than
Commercial or any affiliate of Commercial.  For purposes of this Agreement
"Acquisition Transaction" shall mean (x) a merger or consolidation, or any
similar transaction, involving the Company or any Company Subsidiary, (y) a
purchase, lease or other acquisition of all or substantially all of the assets
of the Company or any Company Subsidiary or (z) a purchase or other acquisition
(including by way of merger, consolidation, share exchange or otherwise) of
securities representing 50% or more of the equity securities of the Company or
any Company Subsidiary; or

          (ii) After a bona fide proposal is made by any person other than
Commercial or any affiliate of Commercial to the Company or its shareholders to
engage in an Acquisition Transaction, either (A) the Company shall have breached
any covenant or obligation contained in this Agreement and such breach would
entitle Commercial to terminate this Agreement or (B) the holders of Company
common stock shall not have approved this Agreement at the meeting of such
shareholders held for the purpose of voting on this Agreement, such meeting
shall not have been held or shall have been cancelled prior to termination of
this Agreement or the Company's Board of Directors shall have withdrawn or
modified in a manner adverse to Commercial the recommendation of the Company's
Board of Directors with respect to this Agreement.

they would otherwise be so entitled.

become employees of Commercial or the Bank after the Acquisition Merger
Effective Time shall be eligible to participate in all benefit plans sponsored

Hawkeye plans shall be maintained by Commercial until such time as such

shall honor all accrued vacation leave for the employees of Company and the
Company Subsidiaries following the Acquisition Merger Effective Time, with full
credit for prior service with Company or Hawkeye for purposes of vesting and
eligibility for participation and co-payments and deductibles.  Commercial
agrees that for a period of ninety (90) days following the Acquisition Merger
Effective Time, any employee of the Company or Hawkeye who is not, and has not
been, a party to an employment or severance agreement with Company or Hawkeye
and whose employment terminates after the Acquisition Merger Effective Time
shall be entitled to receive payment for accrued vacation time, provided such
accrued vacation time does not exceed five weeks, and a severance payment in

the Commercial health insurance plan following the Acquisition Merger Effective
Time, there shall be no exclusion from coverage for pre-existing conditions that
were covered under any health insurance plan of the Company or Hawkeye.

          Commercial agrees to honor the employment and severance agreements
disclosed in Schedule 2.12, as such agreements may be amended by mutual
agreement of the parties hereto.  Commercial further agrees that the Acquisition
Merger will constitute a change in control for purposes of such agreements.
Commercial further agrees that the severance agreements with Ms. Berg and
Messrs. Runyan, Schmitz and Aldrich may be amended prior to the Acquisition
Effective Time to provide that, for purposes of Section 2(a) of such agreements,
"involuntary termination" shall include the officer's resignation following the
relocation of the officer's principal place of employment immediately prior to
the Acquisition Merger Effective Time.  The Company agrees to use its reasonable

                                     A-52
<PAGE>
 
best efforts to amend the employment agreements with Messrs. Peterson, Schreck
and Riddle prior to the Acquisition Merger Effective Time to provide that at the
Acquisition Merger Effective Time and for a period of 120 days thereafter, each
such officer may voluntarily resign from any position in which they are retained
by Commercial or the Bank and receive the amounts payable under Section 5 of
such agreements.

                           ASSET MANAGEMENT AGREEMENT


     AGREEMENT dated this 16th day of May, 1996 by and among Commercial Federal
Corporation ("CFC"), Commercial Federal Bank, A Federal Savings Bank (the
"Bank"), Heritage Financial, Ltd. ("Heritage") and Hawkeye Federal Savings Bank
("Hawkeye") (collectively, the "Parties").

     On the date hereof, the Parties have entered into a Reorganization and
Merger Agreement (the "Merger Agreement") which provides for the merger of
Heritage with and into CFC, with CFC as the surviving company and the merger of
Hawkeye with and into the Bank, with the Bank as the surviving institution.
Capitalized terms not otherwise defined herein shall have the meaning ascribed
thereto in the Merger Agreement.

     WHEREAS, pursuant to the Merger Agreement, the Bank will succeed to all of
the assets of Hawkeye, including the Bennett Funding Asset; and

     WHEREAS, the Parties have agreed that all value recovered on the Bennett
Funding Asset is to be distributed to those individuals who were stockholders or
option holders of Heritage immediately prior to the Acquisition Merger Effective
Time (collectively, the "Heritage Stockholders"); and

     WHEREAS, the Parties wish to establish a procedure for managing and
disbursing the recovered value of the Bennett Funding Asset following the
Acquisition Merger Effective Time to the Heritage Stockholders.

     NOW, THEREFORE, in consideration of the mutual agreements hereinafter set
forth, the Parties agree as follows:

Formation and Functions of the Bennett Funding Asset Committee
- --------------------------------------------------------------

1.   Effective upon the Acquisition Merger Effective Time, the Bennett Funding
     Asset and all attempts to recover value thereon shall be administered by a
     committee (the "Committee") consisting of three individuals, two of whom
     shall be individuals appointed by Hawkeye and the other of whom shall be
     the Chairman of the Credit Committee of the Bank.  The Committee shall meet
     every 90 days or as needed (either telephonically or in person) to review
     any developments related to the Bennett Funding Asset.

2.   In the event that any member of the Committee resigns or is otherwise
     unable to serve, a replacement shall be designated by (i) the remaining
     representative of Hawkeye, in the event such individual was a
     representative of Hawkeye, (ii) the former directors of Hawkeye in the
     event both representatives of Hawkeye simultaneously become unable to
     serve, or (ii) a duly authorized officer of the Bank in the event such
     individual was the representative of the Bank.

3.   The Committee shall be obligated to use its good faith best efforts to
     collect any and all value recoverable on the Bennett Funding Asset
     ("Bennett Value"), including, but not limited to, through the sale thereof,
     and to distribute such Bennett Value to the Heritage


                                     A-57
<PAGE>
 
     Stockholders.  The Committee shall (a) monitor the progress of the
     collection of the Bennett Value by the Managers (as defined below), (b) in
     accordance with the provisions hereof, pay all expenses associated
     therewith out of the recovered Bennett Value, (c) use its best efforts to
     maintain a current list of the names and addresses of the Heritage
     Stockholders (such a list as of the Acquisition Merger Effective Time shall
     be attached to this Agreement as Exhibit A promptly following the Closing),
     and (d) distribute the recovered Bennett Value to the Heritage Stockholders
     in accordance with the provisions hereof.

4.   All decisions of the Committee shall be approved by a majority of the
     members of the Committee with the exception that decisions to pursue
     litigation reasonably estimated to involve expenditures in excess of the
     amount recovered or held in reserve on the Bennett Funding Asset must be
     approved by a unanimous vote of the Committee's members.

5.   All reasonable and documented expenses incurred by Committee members in the
     performance of their duties hereunder shall be reimbursed from the
     recovered Bennett Value.

6.   The Bank agrees to indemnify the Committee members for any liability
     arising out of the performance of their duties as set forth herein, except
     where such liability arises from the member's gross negligence or willful
     misconduct.  In no case, however, shall the Bank's liability for
     indemnification hereunder exceed the recoverable value of the Bennett
     Funding Asset as of the date hereof.

Appointment of the Managers
- ---------------------------

7.   The Bennett Funding Asset shall be managed by such individuals designated
     by the Bank who serve in the Bank's corporate credit group (the
     "Managers").  The Bank agrees that the Managers will use their best efforts
     to collect the Bennett Value.  In no event, however, will the Bank be
     obligated to incur any expenses in the collection of the Bennett Value.
     All such expenses shall be paid out of the recovered proceeds of the
     Bennett Funding Asset.

8.   The Bank shall be compensated for the time spent by the Managers in
     collecting the Bennett Value at the rate of $50 per hour for a principal
     officer such as the Chairman of the Bank's Credit Committee (or such other
     officer of similar position) and $35 per hour for an associate officer.  In
     addition, all expenses incurred by the Managers in connection with the
     collection of the Bennett Value shall be reimbursed by the Committee from
     such Bennett Value.  The Managers shall submit time sheets on at least a
     bi-monthly basis reflecting the actual time spent in collecting the Bennett
     Value.

9.   The Managers shall be authorized to take all actions necessary in their
     judgment to collect the Bennett Value with the exception that (i) no
     litigation may be commenced and (ii) no sale of the Bennett Funding Asset
     may be effectuated, without the prior written approval of the Committee.

                                     A-58
<PAGE>
 
10.  The Managers shall be obligated to make such progress reports on the
     collection of the Bennett Value as the Committee may reasonably request.

11.  The Bank's obligation hereunder to provide Managers may be terminated at
     the sole option of the Bank at any time beginning one year after the
     Acquisition Merger Effective Time if the hours actually spent by one or
     more Managers exceeds 160 hours within a six-month period.  In the event of
     such early termination, the Committee may appoint another person or entity
     to manage the Bennett Funding Asset and seek to collect the Bennett Value
     upon such terms and conditions as the Committee may determine; provided
     that in no event may the term of such alternative engagement exceed the
     term of this Asset Management Agreement.

Distribution of Proceeds
- ------------------------

12.  All proceeds from the collection of the Bennett Value shall be held in a
     federally insured, interest-bearing deposit account.  Such proceeds shall
     be applied as follows:  (a) first, to pay any and all unpaid reasonable and
     documented expenses associated with such collection; (b) second, to
     establish a reserve in an amount necessary to pay the expenses reasonably
     expected to be incurred in the following 30 days as determined by the
     unanimous vote of the Committee; (c) third, to the Heritage Stockholders
     based on their pro rata interest in Heritage immediately prior to the
     Acquisition Merger Effective Time as set forth on Exhibit A hereto.

13.  Distributions shall be made on an annual basis beginning on or about the
     first anniversary date of the Acquisition Merger Effective Time; provided,
     however, that where the recovered Bennett Value (net of the expenses and
     after establishing the reserve referred to in subparagraph (b) of the
     preceding paragraph) exceeds $100,000, distributions shall be made semi-
     annually.

Termination of this Agreement
- -----------------------------

14.  This Agreement will terminate upon the earlier of (i) the full collection
     of the Bennett Value, through sale or otherwise, and the distribution of
     the proceeds collected thereon to the Heritage Stockholders or (ii)
     September 30, 1999; provided, however, that this date shall be extended to
     December 31, 1999 if in the reasonable good faith and unanimous opinion of
     the Committee, immediately prior to September 30, 1999, further collection
     efforts are warranted.

15.  If, upon the date of termination of this Agreement, there remain net
     proceeds attributable to the Bennett Value which have been collected but
     not distributed to the Heritage Stockholders, such proceeds shall be
     distributed to the Heritage Stockholders as soon as practicable following
     termination of this Agreement; provided that any unpaid expenses, including
     the costs associated with the distribution of the proceeds, shall be
     deducted prior to distribution.

16.  All funds received from the collection of the Bennett Value subsequent to
     the termination of this Agreement will be for the benefit of the Bank.

     operation of law or otherwise, without the prior written consent of the
     other parties.  Subject to the preceding sentence, this Agreement will be
     binding upon, inure to the benefit of and be enforceable by the parties and
     their respective successors and assigns.

Rights of Heritage Stockholders
- -------------------------------

18.  It is hereby acknowledged by the Parties hereto that the Heritage
     Stockholders are third-party beneficiaries of this Agreement; provided,
     however, that (i) no Heritage Stockholder may file an action in an attempt
     to enforce its rights under this Agreement unless such Heritage Stockholder
     has been named as the designated representative of Heritage Stockholders
     representing at least 25% of the shares of Heritage common stock
     outstanding immediately prior to the Acquisition Merger Effective Time, and
     (ii) Commercial's liability on claims to shareholders hereunder shall in no
     event exceed the recoverable value of the Bennett Funding Asset as of the
     date hereof.  Except to the extent that expenses incurred in the collection
     of the Bennett Value are deducted from gross proceeds collected prior to
     distribution to the Heritage Stockholders in accordance with the provisions
     hereof and except for any expenses incurred by the Heritage Stockholders in
     connection with an attempt to enforce their rights hereunder, the Heritage
     Stockholders shall not incur any liability in connection with the
     transactions contemplated by this Agreement.

Applicable Law
- --------------

     governed by and construed in accordance with the internal laws of the State

     2.  Paragraph 12 of the Asset Management Agreement is hereby amended to 
read as follows:

     "All proceeds from the collection of the Bennett Value shall be held in a

     documented expenses associated with such collection; (b) second, to
     establish a reserve in an amount necessary to pay the expenses reasonably
     expected to be incurred in the following 30 days as determined by the

Board of Directors
Heritage Financial, Ltd.
715 Eighth Street
Boone, IA 50036

Members of the Board:

     We understand that Heritage Financial, Ltd., an Iowa corporation 
("Heritage"), its wholly-owned subsidiary, Hawkeye Federal Savings Bank, a 
federally-chartered savings bank ("Hawkeye" and, collectively with Heritage, the
"Sellers"), and Commercial Federal Corporation, a Nebraska corporation 
("Commercial"), and its wholly-owned subsidiary, Commercial Federal Bank, a 
federally-chartered savings bank (the "Bank" and, collectively with Commercial, 
the "Buyers"), have entered into a Reorganization and Merger Agreement, dated as
of May 14, 1996 (the "Agreement"), pursuant to which Heritage will merge with 
and into Commercial, followed by the merger of Hawkeye with and into the Bank 
(collectively, the "Merger").

     As set forth in the Agreement, each of the outstanding shares of Heritage
common stock, including outstanding stock options (collectively "Heritage Common
Stock") will be converted into and have the right to receive, pursuant to
Section 1.3(a)(i)(A) of the Agreement (the "Exchange Ratio"), the following: (i)
an amount in cash equal to no less than $18.73 (the "Cash Consideration" as
adjusted); (ii) that number of shares of Commercial common stock ("Commercial
Common Stock") arrived at by dividing $97.88 by the average NYSE closing price
(as defined by Section 1.3(b) of the Agreement (the "Stock Consideration").
Furthermore pursuant to Section 1.15 of the Agreement, the Heritage shareholders
have the potential to receive an additional amount in cash up to $5.74, which
may be received subsequent to Closing, depending upon the level of collections
by Commercial subsequent to Closing on a leasing portfolio owned by Hawkeye
which was purchased from Bennett Funding Corporation, an entity which recently
declared bankruptcy (the "Bennett Transfer Consideration"). In connection
therewith, you have requested our opinion as to the fairness of the Merger
Consideration (as defined in the Agreement), from a financial point of view, to
the shareholders of Heritage. For purposes of this opinion, we have assumed that
the Bennett Transfer Consideration portion of the Merger Consideration is
allocated a zero ($0.00) value, and that shareholders of Heritage receive no
additional cash, even though the management of Heritage believes (and we concur)
that some portion of the $5.74 in maximum Bennett Transfer Consideration will be
received by shareholders of Heritage.

     Hovde Financial, Inc. ("Hovde") specializes in providing investment banking
and financial advisory services to commercial bank and thrift institutions. Our 
principals are experienced in the independent valuation of securities in 
connection with negotiated underwritings, subscription and community offerings, 
private placements, merger and acquisition transactions and recapitalizations. 
We are familiar with Heritage, having entered into a consulting agreement with 
Heritage pursuant to which we have acted as its financial advisor in connection 
with, and having participated in the negotiations leading, to the Agreement. 
Pursuant to this consulting agreement, we have received and will receive 
compensation from Heritage in connection with our services, a significant 
portion of which is contingent upon the consummation of the Merger.
    
     During the course of our engagement, we reviewed and analyzed material 
bearing upon the financial and operating conditions of Heritage and Commercial 
and material prepared in connection with the proposed transaction, including the
following: the Agreement; certain publicly available business and financial 
information concerning Heritage and Commercial; certain unaudited financial 
information as of June 30, 1996 for Heritage and Commercial; the terms of 
recent merger and acquisition transactions involving thrifts and thrift holding 
companies that we considered relevant; historical market prices and trading 
volumes for Commerical Common Stock; and certain financial and other information
provided to us by the managements of Heritage and Commercial. We also compared 
Heritage and Commercial from a financial point of view with certain other 
companies we deemed to be relevant.     

     In addition, we have conducted meetings with members of the senior 
management of Heritage and Commercial for the purpose of reviewing the future 
prospects of Heritage and Commercial. We also evaluated the pro forma ownership 
of Commercial Common Stock by Heritage's shareholders relative to the pro forma 
contribution of Heritage's assets, liabilities, equity and earnings to the pro 
forma company, and conducted such other studies, analyses and examinations as we
deemed appropriate. We also took into account our assessment of general 
economic, market and financial conditions and our experience in other 
transactions, as well as our knowledge of the bank and thrift industries and
our general experience in securities valuations.
    
     In rendering this opinion, we have relied upon and assumed, without 
independent verification, the accuracy and completeness of the financial and 
other information and representations that were provided or made available to 
us by Heritage, Commercial and their respective representatives and of the 
publicly available information reviewed by us. We also relied upon Commercial's 
management as to the reasonableness and achievability of the financial and 
operating forecasts provided to us. In that regard, we assumed that such 
forecasts reflected the best currently available estimates and judgments of 
Commercial's management and that such projections and forecasts would be 
realized in the amounts and in the time periods currently

estimated by Commercial's management. We did not independently verify and have 
relied on and assumed that the aggregate allowances for loan losses set forth in
the balance sheets of each of Heritage and Commercial at June 30, 1996 were 
adequate to cover potential losses and complied fully with applicable law, 
regulatory policy and sound banking practices as of the date of such financial 
statements. We were not retained to and did not conduct a physical inspection of
any of the properties or facilities of Heritage or Commercial, nor did we make 
any independent evaluation or appraisal of the assets, liabilities or prospects 
of Heritage or Commercial; we were not furnished with any such evaluation or 
appraisal. In addition, we were not retained to and did not review any 
individual credit files.     

     We have assumed that the Merger is, and will be, in compliance with all 
laws and regulations that are applicable to Heritage and Commercial. In 
rendering this opinion, we have been advised by Heritage and Commercial and we 
have assumed that there are not factors that would impede any necessary 
regulatory or governmental approval for the Merger and we have further assumed 
that in the course of obtaining the necessary regulatory and governmental 
approvals, no restriction will be imposed on Commercial or the surviving 
corporation that would have a material adverse effect on Commercial or the 
contemplated benefits of the Merger. We have also assumed that there would not 
occur any change in the applicable law or regulation that would cause a material
adverse change in the prospects or operations of Commercial or the surviving 
corporation after the Merger.

     Our opinion is based solely upon the information available to us and the 
economic, market and other circumstances as they exist as of the date hereof. 
Events occurring after and information that becomes available after the date 
hereof could materially affect the assumptions and analyses used in preparing 
this opinion. We have not undertaken to reaffirm or revise this opinion or 
otherwise comment upon any events occurring or information that becomes 
available after the date hereof.

     We are not expressing any opinion herein as to the prices at which shares 
of Commercial Common Stock issued in the Merger may trade if and when they are 
issued or at any future time, nor does our opinion constitute a recommendation 
to any holder of Heritage Common Stock as to how such holder should vote with 
respect to the Agreement at any meeting of holders of Heritage Common Stock.

     This letter is solely for the information of the Board of Directors and 
stockholders of Heritage and is not to be used, circulated, quoted or otherwise 
referred to for any other purpose, nor is it to be filed with, included in or 
referred to in whole or in part in any registration statement, proxy statement 
or any other document, except in each case in accordance with our prior written 
consent which shall not be unreasonably withheld; provided, however, that we

hereby consent to the inclusion and reference to this letter in any registration
statement, proxy statement, information statement or tender offer document to 
be delivered to the holders of Heritage Common Stock in connection with the 
Merger if and only if this letter is quoted in full or attached as an exhibit to
such document and this letter has not been withdrawn prior to the date of 
such document.

     Subject to the foregoing and based on our experience as investment bankers,
our activities and assumptions as described above, and other factors we have 
deemed relevant, we are of the opinion that, as of the date hereof, the Merger 
Consideration is fair, from a financial point of view, to the shareholders of 
Heritage.

       2.    A shareholder entitled to dissent and obtain payment for the

  registered in that shareholder's name only if the shareholder dissents with
  respect to all shares beneficially owned by any one person and notifies the
  corporation in writing of the name and address of each person on whose behalf
  the shareholder asserts dissenters' rights.  The rights of a partial dissenter
  under this subsection are determined as if the shares as to which the
  shareholder dissents and the shareholder's other shares were registered in the

                                      C-3
<PAGE>
 
       2.    The shareholder who demands payment and deposits the shareholder's

  action.

       3.    A shareholder who does not demand payment or deposit the

  dissenters' notice, is not entitled to payment for the shareholder's shares
  under this division.

  490.1324.  SHARE RESTRICTIONS. -- 1.  The corporation may restrict the

  released under section 490.1326.

       2.    The person for whom dissenters' rights are asserted as to
  uncertificated shares retains all other rights of a shareholder until these

  dissenter's demand.  The corporation shall send with its offer a statement of

  490.1328  PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR OFFER. -- 1.
  A dissenter may notify the corporation in writing of the dissenter's own
  estimate of the fair value of the dissenter's shares and amount of interest
  due, and demand payment of the dissenter's estimate, less any payment under
  section 490.1325, or reject the corporation's offer under section 490.1327 and
  demand payment of the fair value of the dissenter's shares and interest due,
  if any of the following apply:

             a.  The dissenter believes that the amount paid under section
       490.1325 or offered under section 490.1327 is less than the fair value of
       the dissenter's shares or that the interest due is incorrectly
       calculated.

             b.  The corporation fails to make payment under section 490.1325
       within sixty days after the date set for demanding payment.

             c.  The corporation, having failed to take the proposed action,
       does not return the deposited certificates or release the transfer
       restrictions imposed on uncertificated shares within sixty days after the
       date set for demanding payment.

       2.    A dissenter waives the dissenter's right to demand payment under
  this section unless the dissenter notifies the corporation of the dissenter's
  demand in writing under subsection 1 within thirty days after the corporation
  made or offered payment for the dissenter's shares.


                                     PART C

  490.1330  COURT ACTION. -- 1.  If a demand for payment under section 490.1328
  remains unsettled, the corporation shall commence a proceeding within sixty
  days after receiving the payment demand and petition the court to determine
  the fair value of the shares and accrued interest.  If the corporation does
  not commence the proceeding within the sixty-day period, it shall pay each
  dissenter whose demand remains unsettled the amount demanded.

       2.    The corporation shall commence the proceeding in the district court
  of the county where a corporation's principal office or, its none in this
  state, its registered office is located.  If the corporation is a foreign
  corporation without a registered office in this state, it shall commence the
  proceeding in the county in this state where the registered office of the
  domestic corporation merged with or whose shares were acquired by the foreign
  corporation was located.

       3.    The corporation shall make all dissenters, whether or not residents
  of this state, whose demands remain unsettled parties to the proceeding as in
  an action against their shares and all parties must be served with a copy of
  the petition.  Nonresidents may be served by registered or certified mail or
  by publication as provided by law.

       4.    The jurisdiction of the court in which the proceeding is commenced
  under subsection 2 is plenary and exclusive.  The court may appoint one or
  more persons as appraisers to receive evidence and recommend decision on the
  question of fair value.  The appraisers have the powers described in the order
  appointing them, or in any amendment to it.  The dissenters are entitled to
  the same discovery rights as parties in other civil proceedings.

       5.    Each dissenter made a party to the proceeding is entitled to
  judgment for either of the following:

             a.  The amount, if any, by which the court finds the fair value of
       the dissenter's shares, plus interest, exceeds the amount paid by the
       corporation.

             b.  The fair value, plus accrued interest, of the dissenter's
       after-acquired shares for which the corporation elected to withhold
       payment under section 490.1327.

  490.1331 COURT COSTS AND COUNSEL FEES. -- 1.  The court in an appraisal
  proceeding commenced under section 490.1330 shall determine all costs of the
  proceeding, including the reasonable compensation and expenses of appraisers
  appointed by the court.  The court shall assess the costs against the
  corporation, except that the court may assess costs against all or some of the
  dissenters, in amounts the court finds equitable, to the extent the court
  finds the dissenters acted arbitrarily, vexatiously, or not in good faith in
  demanding payment under section 490.1328.

       2.    The court may also assess the fees and expenses of counsel and
  experts for the respective parties, in amounts the court finds equitable, for
  either of the following:

             a.  Against the corporation and in favor of any or all dissenters
       if the court finds the corporation did not substantially comply with the
       requirements of section 490.1320 through 490.1328.

             b.  Against either the corporation or a dissenter, in favor of any
       other party, if the court finds that the party against whom the fees and
       expenses are assessed acted arbitrarily, vexatiously, or not in good
       faith with respect to the rights provided by this chapter.

       3.    If the court finds that the services of counsel for any dissenter
  were of substantial benefit to other dissenters similarly situated, and that
  the fees for those services should not be assessed against the corporation,
  the court may award to these counsel reasonable fees to be paid out of the
  amounts awarded the dissenters who were benefited.
