                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              AS OF AND FOR THE NINE MONTHS ENDED MARCH 31, 1998
                                  (Unaudited)

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

A.  BASIS OF CONSOLIDATION AND PRESENTATION:
    ----------------------------------------

The unaudited consolidated financial statements are prepared on an accrual basis
and include the accounts of Commercial Federal Corporation (the Corporation) and
its wholly-owned subsidiary, Commercial Federal Bank, a Federal Savings Bank
(the Bank), and all majority-owned subsidiaries.  All significant intercompany
balances and transactions have been eliminated.

During the three months ended March 31, 1998, the Corporation consummated the 
acquisitions of First National Bank Shares, LTD, (First National), Liberty
Financial Corporation (Liberty) and Mid Continent Bancshares, Inc. (Mid
Continent). The accounts and results of operations of First National are
reflected in the Corporation's consolidated financial statements beginning
January 30, 1998 since the acquisition was accounted for as a purchase. The
Liberty and Mid Continent acquisitions were accounted for as pooling of
interests and, accordingly, the Corporation's historical consolidated financial
statements were restated for all periods prior to these acquisitions to include
the accounts and results of operations of Liberty and Mid Continent. See Note B
for additional information regarding these mergers.

The accompanying interim consolidated financial statements have not been audited
by independent auditors. However, in the opinion of management, all adjustments
(consisting only of normal recurring adjustments, the required restatement of
all periods prior to the mergers with Liberty and Mid Continent and the merger
expenses and other nonrecurring charges recorded during the first nine months of
fiscal year 1998) considered necessary to fairly present the financial
statements have been included. The consolidated financial statements should be
read in conjunction with the audited financial statements and notes thereto
included in the Corporation's June 30, 1997, Annual Report to Stockholders. The
results of operations for the three and nine month periods ended March 31, 1998,
are not necessarily indicative of the results which may be expected for the
entire fiscal year 1998. Certain amounts in the prior fiscal year periods have
been reclassified for comparative purposes.

B.  CONSUMMATED ACQUISITIONS:
    -------------------------

First National Bank Shares, LTD.  On January 30, 1998, the Corporation
consummated its acquisition of First National, parent company of First United
National Bank and Trust Company. Under the terms of the merger agreement, all of
the outstanding shares of First National's common stock were exchanged for
992,842 shares of the Corporation's common stock. Based on the Corporation's
closing price on January 30, 1998, of $32.50 per share, the exchange of the
Corporation's common stock resulted in a total aggregate value approximating
$32,267,000. At January 30, 1998, before purchase accounting adjustments, First
National had assets of approximately $147,800,000, deposits of approximately
$131,300,000 and stockholders' equity of approximately $12,000,000. First
National operated seven branches located in Kansas. This acquisition has been
accounted for as a purchase with core value of deposits resulting from this
transaction to be amortized on an accelerated basis over a period not to exceed
10 years and goodwill to be amortized on a straight line basis over a period not
to exceed 20 years. The acquisition and operations of First National are not
material to the Corporation.

Liberty Financial Corporation.  On February 13, 1998, the Corporation
consummated its acquisition of Liberty, a privately held commercial bank and
thrift holding company. Pursuant to the terms of the merger agreement, all
8,748,500 outstanding shares of Liberty's common stock were exchanged for
4,015,555 shares of the Corporation's common stock (exchange ratio of .459 based
on an average closing price of $33.7062) for total consideration of
approximately $135,349,000. Liberty operated 38 branches in Iowa and seven in
the metropolitan area of Tucson, Arizona and at January 31, 1998, had assets of
approximately $658,100,000, deposits of approximately $569,800,000 and
stockholders' equity of approximately $50,100,000. This acquisition was
accounted for as a pooling of interests.

Mid Continent Bancshares, Inc. On February 27, 1998, the Corporation consummated
its acquisition of Mid Continent, parent company of Mid-Continent Federal
Savings Bank.  Pursuant to the terms of the merger agreement, all outstanding
shares of Mid Continent's common stock were exchanged for 2,641,945 shares of
the Corporation's common stock (exchange ratio of 1.3039 based on an average
closing price of $32.9156) for total consideration of approximately $86,961,000.
Mid Continent operated ten branches located in Kansas and at February 27, 1998,
had total assets of approximately $405,700,000, deposits of approximately
$258,600,000 and stockholders' equity of approximately $41,200,000. This
acquisition was accounted for as a pooling of interests.

Results of operations for Liberty were reported on a calendar year basis prior
to its merger into the Corporation.  However, in restating prior periods for the
most recent fiscal year, Liberty's accounts and results of operations were
conformed to the Corporation's four quarters ended June 30, 1997.  Accordingly,
in changing fiscal years, Liberty's accounts and results of operations for the
six months ended June 30, 1996, were excluded from reported results of
operations for the restated combined companies. As such, the following table
summarizes the details of changes in retained earnings for such period:

C.   MERGER EXPENSES AND OTHER NONRECURRING CHARGES:
     -----------------------------------------------

The Corporation incurred merger expenses and other nonrecurring charges totaling
$18,907,000 and $22,524,000, respectively, for the three and nine months ended
March 31, 1998, associated with the Liberty and Mid Continent acquisitions and
the impairment in the value of certain computer systems and software pursuant to
systems conversions necessitated by Year 2000 compliance. During the three
months ended March 31, 1998 the Corporation finalized its Year 2000 plans 
resulting in the recorded impairment reducing to fair value the carrying amount
of such computer systems and software which will be depreciated until their
disposal at the date of conversion. Other nonrecurring charges not classified in
the "merger expenses" category are included in certain other categories of the
Consolidated Statement of Operations and are so noted on the following table.

D.  PENDING ACQUISITIONS:
    ---------------------

Perpetual Midwest Financial, Inc.  On December 15, 1997, the Corporation entered
into a reorganization and merger agreement with Perpetual Midwest Financial,
Inc.  (Perpetual), parent company of Perpetual Savings Bank, FSB.  Under the
terms of the merger agreement, the Corporation will acquire in a tax-free
reorganization all of the outstanding shares of Perpetual's common stock in
exchange for the Corporation's common stock.  Perpetual's shareholders will
receive .8636 shares of the Corporation's common stock for each outstanding
share of Perpetual's common stock.  Based on the Corporation's closing price on
March 31, 1998, of $36.375 per share, the transaction would result in the
exchange of approximately 1,533,548 shares of the Corporation's common stock
with a total aggregate value of approximately $55,783,000.

At March 31, 1998, Perpetual had total assets of approximately $402,000,000,
deposits of approximately $320,600,000, and stockholders' equity of
approximately $36,100,000.  Perpetual operates five branches located in Iowa.
This pending acquisition is expected to be completed May 29, 1998 and to be
accounted for as a pooling of interests.

AmerUs Bank.   On February 11, 1998, the Corporation entered into a stock
purchase agreement to acquire AmerUs Bank, a wholly-owned subsidiary of AmerUs
Group Co.  AmerUs Bank is a federally chartered savings bank headquartered in
Des Moines, Iowa.  Under the terms of the agreement, the Corporation will
acquire through a taxable acquisition all of the outstanding shares of AmerUs
Bank's common stock.  As of March 31, 1998, the total purchase consideration
approximates $205,434,000 and consists of (i) cash totaling approximately
$95,750,000 (subject to certain adjustments), (ii) a one-year promissory note
for $40,000,000 with interest based on 150 basis points over the one-year
Treasury bill rate, and (iii) either 1,915,709 shares of the Corporation's
common stock or the cash equivalent of such shares ($69,684,000 at March 31, 
1998) subject to election by the
Corporation.

At March 31, 1998, AmerUs Bank had total assets of approximately $1.365 billion,
deposits of approximately $991.7 million and stockholder's equity of
approximately $104.1 million. AmerUs Bank operates 48 branches located in Iowa
(27), Missouri (8), Nebraska (6), Kansas (4), Minnesota (2) and South Dakota
(1).  This pending acquisition, which is subject to regulatory approvals and
certain other conditions, is expected to close in the third quarter of calendar
year 1998. This acquisition is expected to be accounted for as a purchase with
core value of deposits resulting from this transaction to be amortized on an
accelerated basis over a period not to exceed 10 years and other intangibles
including goodwill to be amortized on a straight line basis over a period not to
exceed 20 years.

D.  PENDING ACQUISITIONS (Continued):
    ---------------------------------

First Colorado Bancorp, Inc.  On March 9, 1998, the Corporation entered into a
reorganization and merger agreement with First Colorado Bancorp, Inc. (First
Colorado). Under the terms of the agreement, the Corporation will acquire in a
tax-free reorganization all of the outstanding shares of First Colorado's common
stock equal to 30 divided by the average closing price (as defined) of the
Corporation's common stock for a 15 day period prior to closing. Such value is
based on an exchange ratio which will float between the Corporation's average
stock prices of $31 to $38 per share. The exchange ratio is fixed at .9677 if
the Corporation's stock price is below $31 per share and at .7895 if the
Corporation's stock price is above $38 per share. Based on the Corporation's
closing stock price of $36.375 at March 31, 1998, the transaction has an
aggregate value of approximately $504,778,000 or $30 per share (exchange ratio
of .8247 totaling 13,877,060 shares of the Corporation's common stock).

First Colorado, headquartered in Lakewood, Colorado, is a unitary savings and
loan holding company and parent of First Federal Bank of Colorado, a federally
chartered stock savings bank that operates 27 branches in Colorado, with
23 branches located in the Denver metropolitan area and four in Colorado's
western slope region. At March 31, 1998, First Colorado had assets of
approximately $1.559 billion, deposits of approximately $1.189 billion and
stockholders' equity of approximately $212.8 million. This pending acquisition
is subject to regulatory approvals, stockholder approval by both the Corporation
and First Colorado shareholders and other conditions outlined in the agreement.
Special stockholder meetings are scheduled for July 3, 1998 for the Corporation
and July 13, 1998 for First Colorado. This pending acquisition is expected to be
completed during the September 30, 1998 quarter and to be accounted for as a
pooling of interests.

E.  COMMITMENTS AND CONTINGENCIES:
    ----------------------------- 

At March 31, 1998, the Corporation issued commitments, excluding undisbursed
portions of loans in process, of approximately $474,950,000 as follows:
$323,521,000 to originate loans, $128,033,000 to purchase loans and $23,396,000
to provide consumers unused lines of credit.  Loan commitments, which are funded
subject to certain limitations, extend over various periods of time.  Generally,
unused loan commitments are canceled upon expiration of the commitment term as
outlined in each individual contract.  These outstanding loan commitments to
extend credit do not necessarily represent future cash requirements since many
of the commitments may expire without being drawn upon. In addition, at March
31, 1998, the Corporation had approximately $420,835,000 in mandatory forward
delivery commitments to sell residential mortgage loans. Loans sold subject to
recourse provisions totaled approximately $24,987,000, which represents the
total potential credit risk associated with these particular loans. Such credit
risk would, however, be offset by the value of the single-family residential
properties which collateralize these loans.

The Corporation is subject to a number of lawsuits and claims for various
amounts which arise out of the normal course of its business.  In the opinion of
management, the disposition of claims currently pending will not have a material
adverse effect on the Corporation's financial position or results of operations.

On September 13, 1994, the Bank commenced litigation against the United States
in the United States Court of Federal Claims seeking to recover monetary relief
for the government's refusal to honor certain contracts between the Bank and the
Federal Savings and Loan Insurance Corporation.  The suit alleges that such
governmental action constitutes breach of contract and an unlawful taking of
property by the United States without just compensation or due process in
violation of the Constitution of the United States.  The litigation status and
process of the multiple legal actions, such as that instituted by the Bank with
respect to supervisory goodwill and regulatory capital credits, make the value
of the claims asserted by the Bank uncertain as to ultimate outcome and
contingent on a number of factors and future events which are beyond the control
of the Bank, both as to substance, timing and the dollar amount of damages which
may be awarded to the Bank if it finally prevails in this litigation.  The Bank 
filed a motion for summary judgement in March 1998. The former Mid Continent 
also filed a similar lawsuit and a motion for summary judgement. The Corporation
would be entitled to any potential awards from Mid Continent lawsuit.

F.  CURRENT ACCOUNTING PRONOUNCEMENTS:
    ----------------------------------

Earnings Per Share:

The Corporation adopted the provisions of Statement of Financial Accounting
Standards No. 128, entitled "Earnings Per Share" (SFAS No. 128) effective
December 15, 1997, and accordingly, restated all prior period earnings per share
to conform with SFAS No. 128. This statement requires dual presentation with
equal prominence of basic and diluted EPS for income from continuing operations
and for net income on the face of the income statement for all entities with
complex capital structures and requires a reconciliation of the numerator and
denominator of the basic EPS computation to the numerator and denominator of the
diluted EPS computation. Basic EPS excludes dilution and is computed by dividing
income available to common stockholders by the weighted-average number of common
shares outstanding for the period. Diluted EPS reflects the potential dilution
that could occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of common
stock that then shared in the earnings of the entity.

Reporting Comprehensive Income:

In June 1997, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards No. 130 entitled "Reporting Comprehensive
Income" (SFAS No. 130).  This statement establishes standards for reporting and
display of comprehensive income and its components in a full set of financial
statements.  Comprehensive income is the total of reported net income and all
other revenues, expenses, gains and losses that under generally accepted
accounting principles bypass reported net income.  SFAS No. 130 requires that
comprehensive income be reported in a financial statement that is displayed with
the same prominence as other financial statements with the aggregate amount of
comprehensive income reported in that same financial statement.  SFAS No. 130
permits the statement of changes in stockholders' equity to be used to meet this
requirement.  Companies are encouraged, but not required, to display the
components of other comprehensive income below the total for net income in the
statement of operations or in a separate statement of comprehensive income.
Companies are also required to display the cumulative total of other
comprehensive income for the period as a separate component of equity in the
statement of financial position.

This statement is effective for fiscal years beginning after December 15, 1997,
or July 1, 1998, for the Corporation, with earlier application permitted.
Companies are also required to report comparative totals for comprehensive
income in interim reports. Management of the Corporation will adopt the
provisions of this statement, which are only of a disclosure nature, effective
July 1, 1998.

Disclosures About Segments of an Enterprise and Related Information:

In June 1997, the FASB issued Statement of Financial Accounting Standards No.
131 entitled "Disclosures About Segments of an Enterprise and Related
Information" (SFAS No. 131).  This statement supersedes SFAS No. 14, "Financial
Reporting for Segments of a Business Enterprise," and utilizes the "management
approach" for segment reporting.  The management approach is based on the way
that the chief operating decision maker organizes segments within a company for
making operating decisions and assessing performance.  Reportable segments are
based on any manner in which management disaggregates its company such as by
products and services, geography, legal structure and management structure.
SFAS No. 131 requires disclosures for each segment that are similar to those
required under current standards with the addition of quarterly disclosure
requirements and more specific and detailed geographic disclosures especially by
countries as opposed to broad geographic regions.   This statement also requires
descriptive information about the way the operating segments were determined,
the products/services provided by the operating segments, the differences
between the measurements used in reporting segment information and those used in
the general purpose financial statements, and the changes in the measurement of
segment amounts from period to period.

The provisions of SFAS No. 131 are effective for fiscal years beginning after
December 15, 1997, or July 1, 1998, for the Corporation, with earlier
application permitted. SFAS No. 131 does not need to be applied to interim
statements in the initial year of application but such comparative information
will be required in interim statements for the second year.  Comparative
information for earlier years must be restated in the initial year of
application.  Management of the Corporation will adopt the provisions of this
statement, which are only of a disclosure nature, effective July 1, 1998.

G.  REGULATORY CAPITAL REQUIREMENTS:
    --------------------------------

The Bank is subject to various regulatory capital requirements administered by
the federal banking agencies. Failure to meet minimum capital requirements can
initiate certain mandatory, and possibly additional discretionary, actions by
regulators that, if undertaken, could have a direct material effect on the
Corporation's financial position and results of operations. The regulations
require the Bank to meet specific capital adequacy guidelines that involve
quantitative measures of the Bank's assets, liabilities, and certain
off-balance-sheet items as calculated under regulatory accounting practices. The
Bank's capital classification is also subject to qualitative judgments by the
regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios as set forth in the
following table of tangible, core and total risk-based capital. Prompt
Corrective Action provisions contained in the Federal Deposit Insurance
Corporation Improvement Act of 1991 (FDICIA) require specific supervisory
actions as capital levels decrease. To be considered well-capitalized under the
regulatory framework for Prompt Correction Action provisions under FDICIA, the
Bank must maintain minimum Tier I leverage, Tier I risk-based and total
risk-based capital ratios as set forth in the following table. At March 31,
1998, and June 30, 1997, the Bank exceeded the minimum requirements for the
well-capitalized category.

The following presents the Bank's regulatory capital levels and ratios relative
to its minimum capital requirements:

                Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                -----------------------------------------------
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                 ---------------------------------------------

During February 1998, the Corporation consummated the acquisitions of Liberty
and Mid Continent. These acquisitions were accounted for as pooling of interests
and, accordingly, the Corporation's historical consolidated financial statements
were restated for all periods prior to these acquisitions to include the
accounts and results of operations of Liberty and Mid Continent.
                                        
LIQUIDITY AND CAPITAL RESOURCES:
--------------------------------

The Corporation's principal asset is its investment in the capital stock of the
Bank, and because it does not generate any significant revenues independent of
the Bank, the Corporation's liquidity is dependent on the extent to which it
receives dividends from the Bank. The Bank's ability to pay dividends to the
Corporation is dependent on its ability to generate earnings and is subject to a
number of regulatory restrictions and tax considerations. Under capital
distribution regulations of the OTS, a savings institution that, immediately
prior to, and on a pro forma basis after giving effect to, a proposed dividend,
has total capital that is at least equal to the amount of its fully phased-in
capital requirements (a "Tier I Association") is permitted to pay dividends
during a calendar year in an amount equal to the greater of (i) 75.0% of its net
income for the recent four quarters, or (ii) 100.0% of its net income to date
during the calendar year plus an amount that would reduce by one-half the amount
by which its ratio of total capital to assets exceeded its fully phased-in risk-
based capital ratio requirement at the beginning of the calendar year. At March
31, 1998, the Bank qualified as a Tier I Association, and would be permitted to
pay an aggregate amount approximating $117.9 million in dividends under these
regulations. Should the Bank's regulatory capital fall below certain levels,
applicable law would require prior approval by the OTS of such proposed
dividends and, in some cases, would prohibit the payment of dividends.

At March 31, 1998, the cash of Commercial Federal Corporation (the parent
company) totaled $31.2 million. On August 11, 1997, the Corporation paid down
its five-year promissory term note by $21.0 million, and paid scheduled
principal payments totaling $1.0 million each quarter, resulting in a remaining
principal balance of $2.0 million with $1.0 million due June 30, 1998 and $1.0
million due September 30, 1998. Due to the parent company's limited independent
operations, management believes that its cash balance at March 31, 1998 is
currently sufficient to meet operational needs. However, the parent company's
ability to make future interest and principal payments on its $50.0 million of
7.95% fixed-rate subordinated extendible notes due December 1, 2006 (the Notes),
on the $2.0 million promissory term note due September 30, 1998, and on its
$46.4 million of 9.375% fixed-rate junior subordinated debentures due May 15,
2027 (the Debentures), is dependent upon its receipt of dividends from the Bank.
Accordingly, excluding any prior activity of Liberty and Mid Continent, for the
three and nine months ended March 31, 1998, dividends totaling $5.415 million
and $14.002 million, respectively, were paid by the Bank to the parent company.
These dividends from the Bank were paid to cover (i) interest payments totaling
$5.470 million on the parent company's debt, (ii) principal payments of $3.0
million on the parent company's promissory term note and (iii) the quarterly
common stock cash dividends totaling $5.532 million payable by the parent
company to its common stock shareholders through March 31, 1998. The Bank will
continue to pay dividends to the parent company, pursuant to regulatory
restrictions, to cover the cash dividends on common stock that the parent
company intends to continue to pay on a quarterly basis and on future principal
and interest payments on the parent company's debt. Dividends totaling $34.7
million were paid by the Bank to the parent company during the nine months ended
March 31, 1997. The parent company also receives cash from the exercise of stock
options and the sale of common stock under its employee benefit plans, as well
as from the Bank for income tax benefits from operating losses of the parent
company as provided in the corporate tax sharing agreement.

The Corporation's primary sources of funds are (i) deposits, (ii) principal
repayments on loans, mortgage-backed and investment securities, (iii) advances
from the Federal Home Loan Bank (FHLB) of Topeka, (iv) cash generated from
operations and (v) securities sold under agreements to repurchase. As reflected
in the Consolidated Statement of Cash Flows, net cash flows used by operating
activities totaled $121.1 million for the nine months ended March 31, 1998, and
net cash flows provided by operating activities totaled $49.2 million for the
nine months ended March 31, 1997. Amounts fluctuate from period to period
primarily as a result of mortgage banking activity relating to the purchase and
origination of loans for resale and the subsequent sale of such loans.

Net cash flows used by investing activities totaled $69.7 million and $215.9
million, respectively, for the nine months ended March 31, 1998 and 1997.
Amounts fluctuate from period to period primarily as a result of (i) principal
repayments on loans and mortgage-backed securities and (ii) the purchase and
origination of loans, mortgage-backed and investment securities. The
acquisitions of First National, Liberty, and Mid Continent (all consummated in
the current fiscal year quarter) had no material effect on liquidity, except for
the cash outlays relating to nonrecurring merger related costs, since such
transactions were consummated in an exchange of common stock between the
Corporation and these respective financial institutions.

LIQUIDITY AND CAPITAL RESOURCES (Continued):
--------------------------------------------

Net cash flows provided by financing activities totaled $191.1 million and
$206.2 million, respectively, for the nine months ended March 31, 1998 and 1997.
Advances from the FHLB have been the primary sources to balance the
Corporation's funding needs during each of the periods presented. The
Corporation experienced a net decrease in retail deposits of $68.3 million for
the nine months ended March 31, 1998, primarily due to depositors leaving for
higher interest rates. Such net decrease is attributable to the three months
ended September 30, 1997, in which retail deposits decreased $106.6 million.
During the nine months ended March 31, 1997, the Corporation utilized securities
sold under agreements to repurchase primarily for liquidity and asset liability
management purposes and the Corporation borrowed $28.0 million to partially
finance the repurchase on August 21, 1996, of 2,812,725 shares of the
Corporation's common stock. As previously discussed, such note presently has a
principal balance of $2.0 million due September 30, 1998. In addition, the
Corporation's $40.25 million 10.25% subordinated debt and $6.9 million 10%
senior notes were paid in full in December 1996 from the proceeds of the
Corporation's $50.0 million 7.95% subordinated extendible notes due December 1,
2006.

The Corporation will continue to grow its franchise through an ongoing program
of selective acquisitions of other financial institutions, as well as through
internal growth. The Corporation has considered and will continue to consider
possible mergers with and acquisitions of other selected financial institutions.
Accordingly, during the nine months ended March 31, 1998, the Corporation
consummated the acquisitions of First National, Liberty and Mid Continent and
entered into agreements with Perpetual, AmerUs Bank and First Colorado. See
Notes B and D in the Notes to the Consolidated Financial Statements for
additional information on these pending and recently consummated acquisitions.
Such acquisitions present the Corporation with the opportunity to further expand
its retail network in its existing markets; and to increase its earnings
potential by increasing its mortgage and consumer loan volumes funded by
deposits which generally bear lower rates of interest than alternative sources
of funds. Acquisition candidates are selected based on the extent to which the
candidate can enhance the Corporation's retail presence in new or existing
markets and complement the Corporation's present retail network.

At March 31, 1998, the Corporation had issued commitments totaling approximately
$475.0 million to fund and purchase loans as follows: $56.5 million of single-
family adjustable-rate mortgage loans, $352.3 million of single-family fixed-
rate mortgage loans, $23.4 million of consumer loan lines of credit and $42.8
million of commercial real estate loans. These outstanding loan commitments to
extend credit in order to originate loans or fund consumer loan lines of credit
do not necessarily represent future cash requirements since many of the
commitments may expire without being drawn. The Corporation expects to fund
these commitments, as necessary, from the sources of funds previously described.
In addition, at March 31, 1998, the Corporation had approximately $420.8 million
in mandatory forward delivery commitments to sell residential mortgage loans.

The maintenance of an appropriate level of liquid resources to meet not only
regulatory requirements but also to provide funding necessary to meet the
Corporation's current business activities and obligations is an integral element
in the management of the Corporation's assets. The Corporation is required by
federal regulation to maintain a minimum average daily balance of cash and
certain qualifying liquid investments equal to 4.0% of the aggregate of the
prior month's daily average savings deposits and short-term borrowings. The
Corporation's liquidity ratio was 9.05% at March 31, 1998. Liquidity levels will
vary depending upon savings flows, future loan fundings, cash operating needs,
collateral requirements and general prevailing economic conditions. The
Corporation does not foresee any difficulty in meeting its liquidity
requirements.

RESULTS OF OPERATIONS:
----------------------

Net income for the three months ended March 31, 1998, was $8.2 million, or $.20
per diluted and basic share, compared to net income of $19.6 million, or $.50
per diluted share ($.51 per basic share) for the three months ended March 31,
1997. The decrease in net income for the three months ended March 31, 1998,
compared to the three months ended March 31, 1997, is primarily due to $18.3
million in merger expenses and other nonrecurring charges recorded in the
current quarter and to net increases of and $2.8 million in general and
administrative expenses and a reduction of $467,000 in total other income. These
decreases to net income were partially offset by increases of $5.5 million in
net interest income after provision for loan losses, a decrease of $3.7 million
in provision for income taxes and a reduction of $892,000 in amortization of
goodwill and core value of deposits.

Net income for the nine months ended March 31, 1998, was $47.5 million, or $1.19
per diluted share ($1.21 per basic share), compared to net income of $34.5
million, or $.88 per diluted share ($.89 per basic share), including an after-
tax loss on early retirement of debt totaling $583,000, or $.01 loss per diluted
share, classified as an extraordinary item, for the nine months ended March 31,
1997. The increase in net income for the nine months ended March 31, 1998,
compared to the nine months ended March 31, 1997, is primarily due to a $27.5
million nonrecurring Federal deposit insurance assessment recorded in fiscal
year 1997, net increases of $10.7 million in net interest income after provision
for loan losses and $6.2 million in total other income, a net reduction

RESULTS OF OPERATIONS (Continued):
----------------------------------

of $3.5 million in amortization expense of intangible assets and the
extraordinary loss on early retirement of debt totaling $583,000 recorded in the
prior fiscal year.  These increases to net income were partially offset by
$19.5 million in merger expenses and other nonrecurring charges recorded in the
current fiscal year and to net increases of $9.5 million in the provision for
income taxes and $6.6 million in general and administrative expenses.

Net Interest Income:
--------------------

Net interest income was $55.8 million for the three months ended March 31, 1998,
compared to $51.0 million for the three months ended March 31, 1997, resulting
in an increase of $4.8 million, or 9.4%. Net interest income was $162.0 million
for the nine months ended March 31, 1998, compared to $148.4 million for the
nine months ended March 31, 1997, resulting in an increase of $13.6 million, or
9.1%. The interest rate spread was 2.73% at March 31, 1998, compared to 2.55% at
March 31, 1997, an increase of 18 basis points. During the three months ended
March 31, 1998 and 1997, interest rate spreads were 2.57% and 2.46%,
respectively, an increase of 11 basis points; and the yield on interest-earning
assets was 2.80% and 2.74% over the same respective periods of time. Interest
rate spreads decreased five basis points from 2.49% to 2.44% during the nine
months ended March 31, 1998, compared to March 31, 1997. Net interest income
increased for nine months ended March 31, 1998, over the nine months ended March
31, 1997, due to the net earnings balance increasing by $37.6 million over the
respective period. The average balance of interest-earning assets increased
$536.0 million and $812.8 million, respectively, for the three and nine months
ended March 31, 1998, compared to the same periods ended March 31, 1997, while
the average balance of interest-bearing liabilities increased $559.2 million and
$775.1 million over the same respective periods of time. The increases in these
average balances are due to the acquisitions of First National on January 30,
1998, Heritage Financial, Ltd. (Heritage) on October 1, 1996, and Investors
Federal Savings (Investors) on May 1, 1997, and to internal growth. The future
trend in interest rate spreads and net interest income will be dependent upon
such factors as the composition and size of the Corporation's interest-earning
assets and interest-bearing liabilities, the interest rate risk exposure of the
Corporation, and the maturity and repricing activity of interest-sensitive
assets and liabilities, as influenced by changes in and levels of both short-
term and long-term market interest rates.

The following table presents certain information concerning yields earned on
interest-earning assets and rates paid on interest-bearing liabilities during
and at the end of each of the periods presented:

</TABLE> 

During the three and nine months ended March 31, 1998, the Corporation
experienced lower costs on interest-bearing liabilities primarily due to
decreases in the interest rates on savings deposits (15 and 18 basis points,
respectively) and other time deposits (three and 24 basis points, respectively).
The net earnings balance (the difference between average interest-bearing
liabilities and average interest-earning assets) decreased by $23.1 million for
the three months ended March 31, 1998, compared to the three months ended March
31, 1997, and increased $37.6 million for the nine months ended March 31, 1998
compared to the same period ended March 31, 1997. Such year to date increase is
primarily due to the acquisition of First National (which was acquired through
the issuance of common stock), the acquisition of Heritage (which was acquired,
in part, through the issuance of common stock), the acquisition of Investors and
net internal growth with earnings retention.

Net Interest Income (Continued):

The table below presents the dollar amount of changes in interest income and
expense for each major component of interest-earning assets and interest-bearing
liabilities, respectively, and the amount of change in each attributable to: (i)
changes in volume (change in volume multiplied by prior year rate), and (ii)
changes in rate (change in rate multiplied by prior year volume).  The net
change attributable to change in both volume and rate, which cannot be
segregated, has been allocated proportionately to the change due to volume and
the change due to rate.  The following table demonstrates the effect of the
increased volume of interest-earning assets and interest-bearing liabilities,
the changes in interest rates and the effect on the interest rate spreads
previously discussed:

</TABLE> 

The net improvements due to changes in volume for the three and nine months
ended March 31, 1998, compared to March 31, 1997, reflect the net growth the
Corporation has experienced, both internally and from acquisitions.  The net
decreases due to changes in rates between the three and nine-month periods ended
March 31, 1998 and 1997, primarily reflect the decrease in rates on interest-
bearing liabilities, primarily savings and other time deposits.

Provision for Loan and Lease Losses and Real Estate Operations:
---------------------------------------------------------------

The Corporation recorded loan and lease loss provisions totaling $2.4 million
and $10.8 million, respectively, for the three and nine months ended March 31,
1998, compared to $3.1 million and $8.0 million, respectively, for the three and
nine months ended March 31, 1997. The provision for the three months ended March
31, 1998, is lower by $728,000 compared to the three months ended March 31,
1997, primarily due to additional general reserves recorded last fiscal year to
cover consumer loan losses. The provision for the nine months ended March 31,
1998 is $2.8 million higher compared to 1997 due primarily to additional
nonrecurring loan loss reserves recorded in the quarter ended December 31, 1997
to conform reserve positions of Liberty and Mid Continent to the policies of the
Corporation. The allowance for loan and lease losses is based upon management's
continuous evaluation of the collectibility of outstanding loans and leases,
which takes into consideration such factors as changes in the composition of the
loan and lease portfolios and economic conditions that may affect the borrower's
ability to pay, regular examinations by the Corporation's credit review group of
specific problem loans and of the overall portfolio quality and real estate
market conditions in the Corporation's lending areas.

The Corporation recorded a net loss from real estate operations of $199,000 and
$136,000, respectively, for the three months ended March 31, 1998 and 1997,
compared to net income of $559,000 and $1.0 million, respectively, for the nine
months ended March 31, 1998 and 1997.  Real estate operations reflect provisions
for real estate losses, net real estate operating activity, and gains and losses
on dispositions of real estate.  The net decrease in real estate operations for
the nine months ended March 31, 1998, compared to the nine months ended March
31, 1997, is primarily due to a decrease in net gains on dispositions of real
estate in the current fiscal year compared to the prior fiscal year.

Nonperforming assets are monitored on a regular basis by the Corporation's
internal credit review and asset workout groups. Nonperforming assets increased
$2.1 million at March 31, 1998 compared to June 30, 1997, resulting from net
increases of $5.1 million in nonperforming loans and leases and $1.1 million in
real estate partially offset by a net decrease of $4.1 million in troubled debt
restructurings. Nonperforming assets as of the dates indicated are summarized as
follows:

    cover risks associated with borrowers' delinquencies and defaults on loans
    held for sale.

(2) Represents the allowance for loan losses for single-family residential whole
    loans purchased between January 1991 and June 30, 1992 (bulk purchased
    loans), which had been allocated from the amount of net discounts associated
    with the Corporation's purchase of these loans to provide for the credit
    risk associated with such bulk purchased loans.  These bulk purchased loans
    had principal balances of $417.5 million, $494.6 million and $516.8 million,
    respectively, at March 31, 1998, June 30, 1997, and March 31, 1997. These
    allowances are available only to absorb losses associated with respective
    bulk purchased loans and are not available to absorb losses from other
    loans.

Provision for Loan and Lease Losses and Real Estate Operations (Continued):
---------------------------------------------------------------------------

The ratio of nonperforming loans and leases to total loans and leases was .72%
at March 31, 1998, based on loan and lease balances of $6.388 billion, compared
to .68% and .74%, respectively, at June 30, 1997, and March 31, 1997, based on
respective loan and lease balances approximating $6.041 billion and $5.797
billion. The ratio of nonperforming assets to total assets was .83% at March 31,
1998, compared to .85% and .93% at June 30, 1997, and March 31, 1997,
respectively. Ratios for nonperforming loans and leases to total loans and
leases increased compared to June 30, 1997, due to increases in such
nonperforming loans and leases, primarily delinquent residential and commercial
real estate loans, and improved compared to March 31, 1997, due primarily to net
increases in total loans and leases. Ratios for nonperforming assets to total
assets improved compared to June 30, 1997 due to increases in total assets and
to March 31, 1997 due to net improvements in total nonperforming assets as well
as increases in total assets. The percentage of allowance for loan and lease
losses to total loans and leases remained unchanged compared to June 30, 1997,
and decreased compared to March 31, 1997, primarily due to net increases in
total loans. The total allowance for loan and lease losses to total
nonperforming assets increased compared to June 30, 1997 primarily due to net
increases of $2.8 million in the loss allowance and at March 31, 1997, due to
net decreases in total nonperforming assets and to net increases in the loss
allowance.

Nonperforming loans and leases at March 31, 1998, increased by $5.1 million
compared to June 30, 1997, primarily due to net increases totaling $2.8 million
for both delinquent residential real estate loans and delinquent commercial real
estate loans. These increases were partially offset by net decreases of $594,000
in leases. The net increase in real estate of $1.1 million at March 31, 1998,
compared to June 30, 1997, is due primarily to the net increase in residential
real estate properties and the capitalization of lot development costs totaling
$2.3 million partially offset by the net dispositions of commercial real estate.
The net decrease of $4.1 million in troubled debt restructurings at March 31,
1998, compared to June 30, 1997, is primarily attributable to the payoff of two
commercial loans totaling $3.8 million.

Loan Servicing Fees:
--------------------

Fees from loans serviced for other institutions totaled $9.8 million and $29.5
million, respectively, for the three and nine months ended March 31, 1998
compared to $10.5 million and $30.4 million, respectively, for the three and
nine months ended March 31, 1997. The decrease comparing the respective periods
is primarily due to a net decrease in loans serviced for other institutions
comparing fiscal year 1998 periods to fiscal year 1997. At March 31, 1998 and
1997, the Corporation's mortgage servicing portfolio approximated $6.951 billion
and $7.282 billion, respectively.

The value of the Corporation's loan servicing portfolio increases as mortgage
interest rates rise and loan prepayments decrease. It is expected that income
generated from the Corporation's loan servicing portfolio will increase in such
an environment. However, this positive effect on the Corporation's income is
offset, in part, by a decrease in additional servicing fee income attributable
to new loan originations, which historically decrease in periods of higher, or
increasing, mortgage interest rates, and by an increase in expenses from loan
production costs since a portion of such costs cannot be deferred due to lower
loan originations. Conversely, the value of the Corporation's loan servicing
portfolio will decrease as mortgage interest rates decline.

Retail Fees and Charges:
------------------------

Retail fees and charges totaled $5.6 million and $17.1 million, respectively,
for the three and nine months ended March 31, 1998, compared to $5.4 million and
$15.7 million, respectively, for the three and nine months ended March 31, 1997.
The net increases result primarily from increases in certain checking account
fees and VISA debit check card fees attributable to a significant increase in
the number of retail checking accounts at March 31, 1998, compared to March 31,
1997.

Gain on Sales of Loans:
-----------------------

The Corporation sold loans to third parties through its mortgage banking
operations resulting in net pre-tax gains of $292,000 and $1.1 million,
respectively, on loans sold totaling $235.7 million and $643.4 million,
respectively, for the three and nine months ended March 31, 1998, compared to
net pre-tax gains of $350,000 and $993,000, respectively, on loans sold totaling
$217.5 million and $695.5 million, respectively, for the three and nine months
ended March 31, 1997. Mortgage loans are generally sold in the secondary market
with loan servicing retained and without recourse to the Corporation. The net
gains are attributable to the relatively stable interest rate environments over
the respective periods.

                                      20
<PAGE>
 
Gain on Sales of Mortgage-Backed Securities:
--------------------------------------------

The Corporation sold mortgage-backed securities available for sale resulting in
net pre-tax gains of $468,000 and $1.5 million, respectively, for the three and
nine months ended March 31, 1998, on sales totaling $37.3 million and $68.0
million, compared to $100,000 for the nine months ended March 31, 1997 on sales
totaling $80.3 million.

Other Operating Income:
-----------------------

Other operating income totaled $3.9 million and $15.3 million, respectively, for
the three and nine months ended March 31, 1998, compared to $4.3 million and
$10.5 million, respectively, for the three and nine months ended March 31, 1997.
The major components of other operating income are brokerage commissions,
credit life and disability commissions and insurance commissions which increased
slightly for the three months ended March 31, 1998, compared to March
31, 1997. However, the net decrease for the three months ended March 31,
1998, compared to 1997 is attributable to nonrecurring charges totaling 
$597,000 recorded in the current fiscal quarter for certain reserves on leasing 
operations acquired in the Liberty merger.

For the nine months ended March 31, 1998, brokerage commissions, credit life and
disability commissions and insurance commissions increased moderately compared
to 1997 with other increases in other operating income for the nine months ended
March 31, 1998, compared to 1997 due primarily to excess trustee funds on debt
payoff totaling $1.2 million, receipts from bankruptcy settlements totaling
$402,000, a net pre-tax gain of $380,000 on the sale of $412,000 of loan
servicing rights and other sundry items.

General and Administrative Expenses:
------------------------------------

General and administrative expenses totaled $56.6 million and $135.1 million,
respectively, for the three and nine months ended March 31, 1998, compared to
$35.5 million and $108.9 million, respectively, for the three and nine months
ended March 31, 1997, excluding the $27.5 million nonrecurring industry-wide
Federal deposit insurance special assessment recorded in the first quarter of
fiscal year 1997. 

The net increase of $21.1 million for the three months ended March 31, 1998,
compared to the three months ended March 31, 1997, was primarily due to merger
expenses totaling $11.5 million recorded in the current fiscal year quarter and
to net increases in data processing of $4.3 million, operating expenses of $2.8
million, compensation and benefits of $1.5 million, advertising of $512,000 and
occupancy and equipment of $588,000.

Such net increase comparing quarters is primarily due to the current merger
expenses totaling $11.5 million (recorded to cover severance and termination
costs of $5.2 million, transaction costs such as investment banking, accounting
and legal costs of $4.7 million and other miscellaneous transition and
conversion expenses of $1.5 million associated with the Liberty and Mid
Continent acquisitions), increased data processing costs totaling 4.3 million
due to the impairment in the value of certain computer systems and software
pursuant to the conversion of systems integrated necessitated by Year 2000
compliance, and to the nonrecurring charges totaling $2.5 million to conform
accounting practices of certain operations of Liberty and Mid Continent to the
Corporation.

The net increase of $26.1 million comparing the nine months ended March 31,
1998, to the nine months ended March 31, 1997, was primarily due to merger
expenses totaling $12.7 million recorded fiscal year to date, and to net
increases of $4.8 million in data processing, $4.1 million in compensation and
benefits, $4.3 million in other operating expenses, $1.8 million in advertising
and $1.6 million in occupancy and equipment. These increases were partially
offset by a net decrease of $3.1 in regulatory insurance and assessments.

The net increase for the nine months ended March 31, 1998, compared to the nine
months ended March 31, 1997, is primarily attributed to merger expenses totaling
$12.7 (recorded to cover severance and termination costs of $5.2 million,
transaction costs of $5.9 million and other miscellaneous transition and
conversion expenses of $1.5 million associated with Liberty and Mid Continent
acquisitions), nonrecurring charges totaling $2.5 million to conform accounting
practices of certain operations of Liberty and Mid Continent to the Corporation,
increased marketing costs for checking accounts and related products and
consumer loans totaling $1.8 million, increased occupancy and equipment
expenses, net increases in general and administrative expenses from
acquisitions, increased data processing costs of which $4.3 million is due to
the impairment in the value of computer systems and software necessitated by
Year 2000 compliance as discussed above and other net increases in employee
benefits and other operating expenses primarily due to branch expansion and
acquisitions over the prior fiscal year period. Partially offsetting these
increases were decreases in regulatory insurance and assessments totaling $3.1
million and nonrecurring expenses totaling $2.3 million recorded in the prior
fiscal year related to the repurchase of 2,812,725 shares of the Corporation's
common stock. The decrease in regulatory insurance and assessments of $3.1
million for the nine months ended March 31, 1998, compared to the respective
prior year period is substantially due to the revised rate structure on insured
deposits adopted by the Federal Deposit Insurance Corporation after the
recapitalization of the Savings Association Insurance Fund. The Corporation's
annual deposit insurance rate in effect prior to this recapitalization was .23%
of insured deposits which was reduced to .18% of insured deposits for the
quarter ended December 31, 1996, and to .064% of insured deposits effective
January 1, 1997, and thereafter.

Amortization of Goodwill and Core Value of Deposits:
----------------------------------------------------

Amortization of goodwill and core value of deposits totaled $2.0 million and
$5.3 million, respectively, for the three and nine months ended March 31, 1998,
compared to $2.9 million and $8.9 million, respectively, for the three and nine
months ended March 31, 1997. The net decreases for the respective periods are
due primarily to the reduction in amortization expense of core value of deposits
since amounts from certain acquisitions were fully amortized as of April 30,
1997.

Provision for Income Taxes:
---------------------------

For the three and nine months ended March 31, 1998, the provision for income
taxes totaled $6.5 million and $28.3 million, respectively, compared to $10.2
million and $18.8 million, respectively, for the three and nine months ended
March 31, 1997. The effective income tax rates for the three and nine months
ended March 31, 1998, were 44.1% and 37.3%, respectively, compared to 34.2% and
34.9%, respectively, for the three and nine months ended March 31, 1997. The
effective tax rates for all periods vary from the applicable statutory rates
primarily due to the nondeductibility of amortization of goodwill and core value
of deposits, and, for the fiscal year 1998 periods, certain merger expenses and
nonrecurring charges, in relation to the level of taxable income for the
respective periods.

Extraordinary Items - Loss on Early Retirement of Debt:
-------------------------------------------------------

In December 1996, the Corporation recognized extraordinary losses of $583,000
(net of income tax benefits totaling $316,000), or $.01 loss per share,
primarily as a result of the early retirement of its $40.25 million 10.25%
subordinated debt due December 15, 1999, and its $6.9 million 10.0% senior notes
due January 31, 1999. The extraordinary losses consisted primarily of the write-
off of the related premiums and costs associated with the issuance and
redemption of such debt which was retired on December 27, 1996, with the
proceeds from the $50.0 million subordinated extendible notes offering completed
December 2, 1996.

Other Matters - Year 2000 Compliance:
-------------------------------------

As the year 2000 approaches, an important business issue has emerged regarding
how existing application software programs and operating systems can accommodate
this date value. Many computer programs that can only distinguish the final two
digits of the year entered (a common programming practice in earlier years) are
expected to read entries for the year 2000 as the year 1900 and compute payment,
interest or delinquency based on the wrong date or are expected to be unable to
compute payment, interest or delinquency. Rapid and accurate data processing is
essential to the operations of the Corporation.

All of the material computer programs of the Corporation that could be affected
by this problem are provided by major third party vendors. Currently, the
Corporation is in the process of replacing/upgrading all computer systems and
programs, as well as most equipment, in order to provide cost-effective and
efficient delivery of services to its customers, information to management, and
to provide additional capacity for processing information and transactions due
to acquisitions. As such, during the three months ended March 31, 1998, the
Corporation recorded a nonrecurring charge of $4.3 million which is the
impairment in value of certain computer systems and software pursuant to systems
conversions necessitated by Year 2000. The adjusted carrying amount of these
computer systems and software will be depreciated until their disposal at the
date of conversion. The third party vendors of the Corporation have advised the
Corporation that all such computer systems and programs will be year 2000
compliant. However, if the third party vendors are unable to resolve year 2000
issues in time, the Corporation would likely experience significant data
processing delays, mistakes or failures. These delays, mistakes or failures
could have a significant adverse impact on the financial condition and results
of operations of the Corporation.

Item 5.  Other Information
         -----------------

  A Special Meeting of Stockholders will be called on July 3, 1998, for
  shareholders of record at May 14, 1998. The purpose of the meeting is to
  consider and act upon:

  (1)  a proposal to approve the First Colorado merger and to approve an
       amendment to the Corporation's Articles of Incorporation to increase the
       number of shares authorized from 50,000,000 to 70,000,000 with such
       additional shares primarily to be issued in this merger;
 
  (2)  an amendment to the Corporation's Articles of Incorporation to further
       increase the number of authorized shares from 70,000,000 to 120,000,000
       shares (in the event the First Colorado merger is not approved, this
       amendment would increase the authorized shares from 50,000,000 to
       100,000,000 shares) which will allow the Corporation to meet its future
       needs and provide greater flexibility in responding to advantageous
       business opportunities including possible future acquisition
       opportunities; 
 
  (3)  an amendment to the Corporation's 1996 Stock Option and Incentive Plan to
       increase the number of shares available for grant to 3,934,250 for
       issuance thereunder; and

  (4)  such other business as may properly come before such special meeting.
