                                     PART I.

ITEM 1. BUSINESS

Corus Bankshares, Inc., 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; trust
and investment management services; safe deposit boxes and a variety of
additional services. The bank also provides clearing, depository and credit
services to more than 550 currency exchanges in the Chicago area and an
additional 20 in Milwaukee, Wisconsin.

Corus owns an operations subsidiary, Bancorp Operations Company, that comprises
an insignificant portion of Corus' total assets and net income. Bancorp
Operations Company provides item processing, bookkeeping and other ancillary
bank support services to Corus' bank subsidiary.

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, 1998, Corus employed a total of 674 full-time equivalent
persons, consisting of 138 executives, management and supervisory personnel and
536 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.

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 



                                       1
<PAGE>   3


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 1999 will be
approximately .01% 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 this
category.

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, 1998, Corus'
Tier 1 capital and total risk-based capital ratios were 15.0% and 18.1%,
respectively.



                                       2
<PAGE>   4


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, 1998, Corus' leverage ratio was 10.3%.

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 also
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.

STATISTICAL DATA

Pages 4 through 10 contain supplemental statistical data. This data should be
read in conjunction with Corus' Management's Discussion and Analysis of
Financial Statements and the Consolidated Financial Statements and notes thereto
of the 1998 Annual Report to Shareholders (1998 Annual Report), incorporated
herein by reference in response to Items 7 and 8 hereof.

The tax-equivalent adjustment for interest income on tax-advantaged loans and
securities is reflected through the rate column based on a marginal corporate
income tax rate of 35%. Volume variances are computed using the change in volume
multiplied by the previous year's rate. Rate variances are computed using the
changes in rate multiplied by the previous year's volume. The change in interest
due to both rate and volume has been allocated between the factors in proportion
to the relationship of the absolute dollar amounts of the change in each.

Of the loans maturing after one year, $269.8 million have fixed 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 pages 41 through 43 of the 1998 Annual
Report, incorporated herein by reference in response to Item 8 hereof.

Guaranteed student loans that are greater than 90 days past due are classified
as performing due to the principal and accrued interest on such loans being
guaranteed by individual state or private non-profit agencies.

Potential Problem Loans

In addition to those loans disclosed under the preceding "Nonaccrual and Past
Due 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, 1998, the principal amount of these loans was $8.5 million. This
amount generally includes loans that were classified for regulatory purposes.

31, 1998 from $157 million at December 31, 1997 (refer to page 24 of the 1998
Annual Report); (ii) unused commitments under existing commercial real estate
lines of credit increased to $243 million at December 31, 1998 from $154 million

ITEM 2. PROPERTIES

Corus utilizes the building facilities of its Irving Park branch, which is
located at 3959 N. Lincoln Avenue, Chicago, Illinois, for its executive offices.
Corus owns the property and buildings on which nine of the eleven bank branch
locations are located. The other two branch locations are leased from unrelated
parties.

ITEM 3. LEGAL PROCEEDINGS

Corus is involved in various legal and regulatory proceedings, many involving
matters that arose in the ordinary course of business. The consequences of these
proceedings are not presently determinable but, in the opinion of management,
these proceedings will not have a material effect on the results of operations,
financial position, liquidity or capital resources of Corus, except possibly for
the matter discussed below.

As disclosed previously, Corus discovered that certain former employees in the
student loan servicing area had falsified some records of telephone calls, from
late 1993 to April 1994, to students whose loans were delinquent. The telephone
calls are a required action to maintain the enforceability of a student loan's
government guarantee. Corus terminated the employees involved and informed the
U.S. Department of Education immediately upon discovery of the problem and the
Department commenced an investigation. The Department's investigation expanded
in 1995 to include a review of whether Corus' student loan division engaged in
improper practices from 1988 to April 1994, including whether information
contained on guarantee claim forms may have been falsified.




                                       9
<PAGE>   11


Shortly after notifying the Department of the problems in the student loan
servicing area, Corus entered into an interim agreement with the Department
pursuant to which it agreed, pending the conclusion of the investigation, not to
request payment from any guarantor or the Department on any loans that Corus is
unable to state with certainty were not affected by incorrect servicing history
documentation. A total of $14.5 million of loans subject to the interim
agreement were charged-off against the allowance for loan losses since 1996. The
ultimate collectibility of these loans is uncertain.

Although certain employees of Corus may have acted illegally or violated
Department policy or regulations, management is unable to predict what actions,
if any, the Department will take following completion of its investigation, and
cannot estimate the magnitude of the violations or the amount or range of any
liability that Corus will ultimately incur. As such, management is unable to
quantify either the amount of student loans that may lose their government
guarantee or the amount of loans that it may be required to repurchase and,
therefore, the effect such amounts and any related penalties will have on Corus'
financial condition or results of operations. No legal proceedings have been
commenced against Corus as a result of the investigation.

If it is ultimately determined that Corus acted illegally or violated Department
policy or regulations with respect to certain loans in a significant number of
instances or if a settlement is reached, Corus could (i) lose its government
guarantees with respect to certain student loans and (ii) be required to
repurchase a substantial amount of delinquent student loans for which Corus
previously received guarantee payments. In addition, Corus or individual
employees could be subject to substantial penalties. If the Department were to
bring an action, and be successful in proving violations of law related to the
student loan program, potential sanctions could include significant fines,
recovery of treble amounts of guarantee payments incorrectly received by Corus
and the suspension of Corus' continued participation in the student loan
program.

Corus does not condone or permit such improper practices and is cooperating
fully with the Department's investigation.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING
        AND FINANCIAL DISCLOSURE

On February 12, 1997, the Audit Committee and Board of Directors of Corus
recommended that the shareholders ratify Arthur Andersen LLP at the annual
meeting as independent accountants of Corus for fiscal 1997. This recommendation
caused the dismissal of KPMG LLP (KPMG) as the independent accountants of Corus
upon the completion of the audit of Corus' financial statements as of and for
the year ended December 31, 1996 and the issuance of their report thereon.

For the year ended December 31, 1996, KPMG's reports on the financial statements
did not contain an adverse or a disclaimer of opinion nor were they qualified or
modified as to uncertainty, audit scope or accounting principles.

For the year ended December 31, 1996 and from December 31, 1996 through the
effective date of the dismissal, there were no disagreements between KPMG and
Corus on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure or any reportable events.

Corus requested that KPMG furnish a letter addressed to the United States
Securities and Exchange Commission stating whether KPMG agrees with the
preceding statements. KPMG's letter dated March 25, 1997 is incorporated by
reference to Corus' Annual Report on Form 10-K for the year ended December 31,
1996.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders of Corus Bankshares, Inc.:

We have audited the accompanying consolidated balance sheets of Corus
Bankshares, Inc. and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, changes in shareholders' equity and
cash flows for the years then ended. These consolidated financial statements are
the responsibility of the Corporation's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audit. The consolidated financial statements of Corus Bankshares, Inc. and
subsidiaries as of December 31, 1996 and for the year ended December 31, 1996,
were audited by other auditors whose report dated January 10, 1997, expressed an
unqualified opinion on those statements.

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 Corus Bankshares,
Inc. and subsidiaries at December 31, 1998 and 1997, and the results of their
operations and cash flows for the years then ended in conformity with generally
accepted accounting principles.
