                                     PART I

ITEM 1. BUSINESS

Corus Bankshares, Inc. ("Corus"), incorporated in Minnesota in 1958, is a bank
holding company registered under the Bank Holding Company Act of 1956. Corus
provides consumer and corporate banking products and services through its
wholly-owned banking subsidiary, Corus Bank, N.A.

The bank has eleven branches in the Chicago metropolitan area and offers general
banking services such as checking, savings, money market and time deposit
accounts; commercial, mortgage, home equity, student and personal loans; safe
deposit boxes and a variety of additional services. The bank also provides
clearing, depository and credit services to more than 525 currency exchanges in
the Chicago area and an additional 20 in Milwaukee, Wisconsin. In October 2000,
Corus sold its trust and investment management services business. In December
2000, Corus sold the majority of its student loans and has an agreement to sell
the remaining balance to the same buyers in the second quarter of 2001.

COMPETITION

All of Corus' principal business activities are highly competitive. Corus
competes actively with other financial services providers offering a wide array
of financial products and services. The competitors include other banks, savings
and loan associations, credit unions, brokerage firms, finance companies,
insurance companies, mutual funds and mortgage bankers. Competition is generally
in the form of interest rates and points charged on loans, interest rates paid
on deposits, service charges, banking hours, fiduciary services and other
service-related products.

EMPLOYEES

At December 31, 2000, Corus employed a total of 579 full-time equivalent
persons, consisting of 127 executives, management and supervisory personnel and
452 clerical and secretarial employees.

SUPERVISION AND REGULATION

General

Corus is a bank holding company within the meaning of the Bank Holding Company
Act of 1956, as amended ("the Act"), and is registered as such with the Board of
Governors of the Federal Reserve System ("the Federal Reserve Board"). The Act
requires every bank holding company to obtain the prior approval of the Federal
Reserve Board before acquiring, merging with or consolidating into another bank
holding company, acquiring substantially all the assets of any bank, or
acquiring direct or indirect ownership or control of 5% or more of the voting
shares of any bank or bank holding company.



                                       1
<PAGE>   3

The Act also prohibits a bank holding company, with certain exceptions, from
acquiring direct or indirect ownership or control of 5% or more of the voting
shares of any company which is not a bank and from engaging in any business
other than that of banking, managing and controlling banks or furnishing
services to banks and their subsidiaries. However, Corus may engage in and own
shares of companies engaged in certain businesses determined by the Federal
Reserve Board to be closely related to banking or managing or controlling banks.

The Illinois Bank Holding Company Act of 1957 ("the Illinois Act"), as amended,
permits Corus to acquire banks located anywhere in Illinois. Other amendments of
the Illinois Act authorize combinations between banks and bank holding companies
located in Illinois and banks and bank holding companies located in another
state if that other state has passed legislation granting similar privileges to
Illinois banks and bank holding companies. Effective December 1, 1990, holding
companies from any state were permitted to acquire Illinois banks and bank
holding companies if the other state allows Illinois bank holding companies the
same privilege. In June 1993, the Illinois Act was amended to eliminate all
branch restrictions. Accordingly, banks located in Illinois are permitted to
establish branches anywhere in the state.

Corus' subsidiary bank is a national bank and, as such, is supervised, examined
and regulated by the Office of the Comptroller of the Currency under the
National Bank Act. Since a national bank is also a member of the Federal Reserve
System and its deposits are insured by the Federal Deposit Insurance Corporation
("FDIC"), the subsidiary bank is also subject to the applicable provisions of
the Federal Reserve Act, the Federal Deposit Insurance Act, and, in certain
respects, to state laws applicable to financial institutions.

The subsidiary bank is subject to FDIC deposit insurance assessments. Under the
FDIC's risk-based assessment system, the assessment rate is based on
classification of a depository institution in one of nine risk assessment
categories. Such classification is based upon the institution's capital level
and upon certain supervisory evaluations of the institution by its primary
regulator. The subsidiary bank's FDIC deposit insurance cost for 2001 will be
approximately 0.02% of deposits.

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
initiated new intense regulation for the financial services industry. FDICIA
made significant changes in the legal environment for insured banks, including
reductions in insurance coverage for certain types of deposits, increases in
consumer-oriented requirements, and substantial revisions in the supervision,
examination and audit processes. FDICIA also required new reporting by banks and
mandated adoption of new regulations concerning capital, liquidity, internal
controls, safety and soundness and prompt corrective action.

Capital Adequacy

The Federal Reserve Board established risk-based capital guidelines that require
bank holding companies to maintain minimum ratios. The main objective of the
risk-based capital requirements is to provide a fair and consistent framework
for comparing capital positions of all banking institutions. Under these
guidelines, capital consists of two components, core capital elements (Tier 1
capital) and supplementary capital elements (Tier 2 capital). Assets and
off-balance-sheet items are assigned broad risk categories. The aggregate dollar
value of each category is multiplied by a risk weight associated with that
category.


                                       2
<PAGE>   4

In 1992, the FDIC adopted new regulations that defined five capital categories
for purposes of implementing the requirements under FDICIA. The five capital
categories, which range from "well-capitalized" to "critically
under-capitalized", are based on the level of risk-based capital measures. The
minimum risk-based capital ratios for Tier 1 capital to risk-weighted assets and
total risk-based capital to risk-weighted assets to be classified as
well-capitalized are 6.0% and 10.0%, respectively. At December 31, 2000, Corus'
Tier 1 capital and total risk-based capital ratios were 16.0% and 18.6%,
respectively.

In addition, bank regulatory agencies established a leverage ratio to supplement
the risk-based capital guidelines. The leverage ratio is intended to ensure that
adequate capital is maintained against risks other than credit risk. A minimum
required ratio of Tier 1 capital to total assets of 3.0% is required for the
highest quality bank holding companies that are not anticipating or experiencing
significant growth. All other banking institutions must maintain a leverage
ratio of 4.0% to 5.0% depending upon an institution's particular risk profile.
At December 31, 2000, Corus' leverage ratio was 14.0%.

Interstate Banking

The Riegle-Neal Interstate Bank and Branching Efficiency Act of 1994 ("IBBA")
permits bank holding companies that are adequately capitalized and managed to
acquire banks located in any other state after September 29, 1995, subject to
certain statewide and nationwide deposit concentration limits. States may
prohibit acquisition of banks that have not been in existence for at least five
years.

The interstate branching by merger provisions were effective on June 1, 1997,
unless a state takes legislative action prior to that date. The long-term
effects on Corus of such changes in interstate banking and branching laws cannot
be predicted. However, it is likely that there will be increased competition
from national and regional banking firms headquartered outside of Illinois.

Graham-Leach-Bliley Act of 1999

The enactment of the Graham-Leach-Bliley Act of 1999 ("the GLB act") repeals
sections 20 and 32 of the Banking Act of 1933 ("the Act"), allowing new
opportunities to be available for banks, other depository institutions,
insurance companies and securities firms to enter into combinations that permit
a single financial services organization to offer customers a more complete
array of financial products and services. To further this goal, the GLB Act
amends section 4 of the Act providing a new regulatory framework for regulation
through the financial holding company ("FHC"), which will have as its umbrella
regulator the Federal Reserve Board. Functional regulation of the FHC's
separately regulated subsidiaries will be conducted by their primary functional
regulator. Pursuant to the GLB Act, bank holding companies, subsidiary
depository institutions thereof and foreign banks electing to qualify as a FHC
must be "well managed", "well capitalized" and at least rated satisfactory under
the Community Reinvestment Act in order for them to engage in new financial
activities. The GLB Act also provides a federal right to privacy of non-public
personal information of individual customers.

Of the loans maturing after one year, $226.7 million have fixed rates and $674.7
million have floating or adjustable rates. To manage the interest rate exposure
of specific, fixed-rate commercial real estate loans and other loans, Corus has
entered into interest rate swap agreements. For additional information on such
financial instruments, see Note 10 to the Consolidated Financial Statements on

The interest income forgone on these loans, net of cash receipts, totaled
$75,000 for the year ended December 31, 2000. In addition, prior year interest
income was reversed for loans becoming nonaccrual in each year. The interest
income reversals totaled $41,000 in 2000.

Loans past due 90 days or more, excluding nonaccrual loans, were as follows:

Potential Problem Loans

In addition to those loans disclosed under the preceding "Nonaccrual, Past Due,
and Restructured Loans" section, management identified, through their problem
loan identification system, certain other loans in the portfolio that exhibit a
higher than normal credit risk. However, these loans were not classified as
nonperforming loans. These other loans include loans that are past maturity more
than 45 days, have recent adverse operating cash flow or balance sheet trends,
or have general risk characteristics that the loan officer feels might
jeopardize the future timely collection of principal and interest payments. At
December 31, 2000, the principal amount of these loans was $17.4 million. This
amount generally includes loans that were classified for regulatory purposes.

</TABLE>


Overall, the allowance at December 31, 2000 increased by $7.5 million versus the
prior year. As the provision was $0 for the year, the increase was driven
entirely by net recoveries. On a classification basis, there were two
significant changes during the year. First, the balance allocated to commercial
real estate increased by $9.4 million reflecting the continued growth in the
commercial real estate portfolio, particularly construction loans (see page 26
in the 2000 Annual Report). Second, the unallocated balance declined by $1.4
million. This unallocated balance is based on management's review of overall
factors affecting the determination of probable losses inherent in the
portfolio, which may not be captured, or captured completely, by the mechanical
application of historical loss ratios and other factors used in determining the
allocated inherent reserve. This portion of the reserve analysis involves the
exercise of judgment and reflects all appropriate considerations, including
management's view that the reserve should have a margin that recognizes the
imprecision inherent in the process of estimating expected credit losses.

Loan Portfolio Composition

The composition of the loan portfolio was as follows:
