Item 7(b).  Pro Forma Financial Information.
- ------------------------------------------- 

On July 31, 1998, Commercial Federal consummated its acquisition of AmerUs.
Under the terms of the Stock Purchase Agreement, Commercial Federal acquired
through a taxable acquisition all of the outstanding shares of the common stock
of AmerUs for total consideration of $178,269,000.  Such consideration consisted
of (i) certain assets retained by AmerUs Group Co. in lieu of cash (primarily
FHA Title One single-family residential mortgage loans and a receivable for
income tax benefits) totaling approximately $85,027,000, (ii) cash (as adjusted
per the agreement) totaling $53,242,000, and (iii) a one-year promissory note
for $40,000,000 bearing interest, adjusted monthly, at 150 basis points over the
one-year Treasury bill rate.  AmerUs was a federally chartered savings bank
headquartered in Des Moines, Iowa and operated 47 branches in Iowa (26),
Missouri (8), Nebraska (6), Kansas (4), Minnesota (2) and South Dakota (1).  The
acquisition was accounted for as a purchase.

On August 14, 1998, Commercial Federal consummated its acquisition of First
Colorado.  Under the terms of the agreement, Commercial Federal acquired in a
tax-free reorganization all 18,564,766 outstanding shares of First Colorado's
common stock in exchange for 18,278,789 shares of its common stock.  Based on
Commercial Federal's closing stock price of $26.375 at August 14, 1998, the
total consideration for this acquisition, including cash paid for fractional
shares, approximated $482,154,000.  An additional requirement of the transaction
with First Colorado was the issuance of 1,400,000 shares of First Colorado
common stock immediately prior to the consummation of the merger.  Such
requirement was necessary to cure the taint on the treasury stock of First
Colorado so this transaction could be accounted for as a pooling of interests.
These shares offered directly by First Colorado resulted in gross cash proceeds
(prior to any transaction costs) of $33,425,000 less the placement agent's
commission of $919,000, or net proceeds to First Colorado totaling $32,506,000.
First Colorado, headquartered in Lakewood, Colorado, was a unitary savings and
loan holding company and the parent company of First Federal Bank of Colorado, a
federally chartered stock savings bank  that operated 27 branches located in
Colorado, with 23 branches located in the Denver metropolitan area and four in
Colorado's western slope region.  The acquisition was accounted for as a pooling
of interests.

The unaudited pro forma combined statement of financial condition as of June 30,
1998, and the unaudited pro forma condensed combined statements of operations
and diluted earnings per share for the fiscal years ended June 30, 1998, 1997
and 1996 presented on the following pages do not include any expected cost
savings or the benefits of related synergies as a result of the mergers of
AmerUs and First Colorado, do not reflect any nonrecurring merger transaction
costs, nor do they reflect all purchase accounting adjustments other than those
described in the accompanying notes, and are not necessarily indicative of the
results that would have occurred if the mergers of AmerUs and First Colorado had
been consummated on June 30, 1998, or had occurred as of the beginning of the
fiscal year ended June 30, 1996 for the First Colorado acquisition accounted for
as a pooling-of-interests and as of the beginning of the fiscal year ended June
30, 1998 for the AmerUs acquisition accounted for as a purchase, or which may be
obtained in the future.

Item 7(b).  Pro Forma Financial Information.
- ------------------------------------------- 

A.   Represents the cash paid and the purchase notes totaling $40,000,000
     executed for the purchase of AmerUs' common stock, the dispositions of
     certain assets of AmerUs per the Stock Purchase Agreement plus the gain
     and/or losses, net of tax, realized upon such dispositions. These pro forma
     adjustments reflect that the cash portion paid for AmerUs' common stock is
     funded in part by a $45,000,000 promissory note with a five-year maturity,
     quarterly principal payments of $1,250,000 and bearing a monthly rate of
     interest which is priced at 100 basis points below the quoted national base
     prime rate.

B.   Represents the elimination of the stockholders' equity accounts of AmerUs
     since this transaction is accounted for as a purchase.

C.   The acquisition of AmerUs is accounted for as a purchase and these pro
     forma adjustments represent the estimated fair value of AmerUs' related
     assets and liabilities. The excess of the purchase price over the fair
     value of the net assets acquired on a pro forma basis is estimated to total
     $110,000,000 of which $16,264,000 is allocated to core value of deposits,
     and $93,736,000 to goodwill for these unaudited pro forma combined
     financial statements.

     The purpose of the issuance of the 1,400,000 shares of First Colorado
     common stock is to permit the merger to be accounted for as a pooling-of-
     interests under generally accepted accounting principles. For purposes of
     these pro forma adjustments the net cash proceeds were assumed to remain in
     non-interest-earning assets.

E.   Represents the tax-free exchange of .9847 shares of Commercial Federal
     common stock for each share of First Colorado common stock (18,564,766 net
     outstanding shares) surrendered in connection with this acquisition,
     adjusted for the issuance of 1,400,000 shares, resulting in 18,278,789
     shares of Commercial Federal common stock issued. No consideration was
     given for fractional shares in these pro forma adjustments. Fractional
     shares were paid in cash.

Nonrecurring pre-tax expenses and charges estimated to approximate $25,000,000
associated with the First Colorado merger are not included in this unaudited
historical pro forma combined statement of financial condition.

Item 7(b).  Pro Forma Financial Information.
- ------------------------------------------- 

A.   The unaudited pro forma condensed combined statements for the fiscal years
     ended June 30, 1998, 1997 and 1996 present the combined revenues and
     expenses and pro forma adjustments as if the mergers of AmerUs and First
     Colorado had occurred as of the beginning of the fiscal year ended June 30,
     1996, for the First Colorado acquisition accounted for as a pooling-of-
     interests, and as of the beginning of the fiscal year ended June 30, 1998
     for the AmerUs acquisition accounted for as a purchase. The pro forma
     adjustments below represent the estimated fair value of the related assets
     and liabilities of AmerUs.

     The excess of the purchase price over the fair value of the net assets of
     AmerUs acquired on a pro forma basis is estimated to total $110,000,000 of
     which $16,264,000 is allocated to core value of deposits and $93,736,000 to
     goodwill for these unaudited pro forma combined financial statements. Net
     income on a pro forma basis was reduced for the accelerated amortization
     expense of core value of deposits estimated over a 10-year period and the
     straight line amortization expense of goodwill estimated over a 20-year
     period; and adjustments were made to interest expense on the $45,000,000
     note, the proceeds of which were used to partially fund the purchase of the
     common stock of AmerUs in this transaction, and on the $40,000,000 purchase
     notes pursuant to the Stock Purchase Agreement.

     The following are the effects of the amortization of the pro forma purchase
     accounting adjustments for AmerUs for the fiscal year ended June 30, 1998,
     assuming this acquisition had been consummated as of the beginning of
     fiscal year 1998.

                        COMMERCIAL FEDERAL CORPORATION
                        ------------------------------

Item 7(b).  Pro Forma Financial Information.
- ------------------------------------------- 

B.   Pro forma combined diluted earnings per common share and weighted average
     diluted common shares outstanding are based upon an exchange ratio of .9847
     and the additional issuance of 1,400,000 shares of First Colorado common
     stock prior to the consummation of the merger. Such pro forma assumptions
     result in the issuance of Commercial Federal weighted average shares of
     common stock totaling 17,408,458, 19,452,027 and 21,095,559, respectively,
     for the years ended June 30, 1998, 1997 and 1996.

C.   Commercial Federal's fiscal year end is June 30, and First Colorado's
     fiscal year end is December 31. Historical results of operations for First
     Colorado for the year ended June 30, 1998, represent its results of
     operations for the four fiscal quarters then ended. Historical results of
     operations for First Colorado for the years ended June 30, 1997, and June
     30, 1996, represent First Colorado's reported results of operations for the
     fiscal years ended December 31, 1996 and 1995, respectively.

Nonrecurring pre-tax expenses and charges estimated to approximate $25,000,000
associated with the First Colorado merger are not included in this unaudited
historical pro forma combined statements of operations.
