PART I

ITEM 1. BUSINESS

Old Second Bancorp, Inc. (the "Company" or the "Registrant") was
organized under the laws of Delaware on September 8, 1981. It is a registered
bank holding company under the Bank Holding Company Act of 1956 (the "Act"). The
Company's office is located at 37 South River Street, Aurora, Illinois 60506.

The Company conducts a full service community banking and trust
business through its wholly-owned subsidiaries, The Old Second National Bank of
Aurora, Yorkville National Bank, Bank of Sugar Grove, Burlington Bank, Kane
County Bank and Trust Company, and Maple Park Mortgage. The banking subsidiaries
are referred to herein as "the Banks." During 1999, the Company simplified its
organizational structure by eliminating two bank charters. The Old Second
Community Bank of North Aurora and Old Second Community Bank of Aurora were
merged into The Old Second National Bank of Aurora ("Old Second").

The Banks' full service banking businesses include the customary
consumer and commercial products and services which banks provide. The following
services are included: demand, savings, time deposit, individual retirement and
Keogh deposit accounts; commercial, industrial, consumer and real estate
lending, including installment loans, student loans, farm loans, lines of credit
and overdraft checking; safe deposit operations; trust services; and an
extensive variety of additional services tailored to the needs of individual
customers, such as the acquisition of U.S. Treasury notes and bonds, the sale of
traveler's checks, money orders, cashier's checks and foreign currency, direct
deposit, discount brokerage debit cards, credit cards, and other special
services.

Commercial and consumer loans are made to corporations, partnerships
and individuals, primarily on a secured basis. Commercial lending focuses on
business, capital, construction, inventory and real estate lending. Installment
lending includes direct and indirect loans to consumers and commercial
customers. Maple Park Mortgage ("Maple Park") originates residential mortgages
and handles the secondary marketing of those mortgages.

The Company's market area is highly competitive. Many financial
institutions based in Aurora's surrounding communities and in Chicago, Illinois,
operate banking offices in the greater Aurora area or actively compete for
customers within the Company's market area. The Company also faces competition
from finance companies, insurance companies, mortgage companies, securities
brokerage firms, money market funds, loan production offices and other providers
of financial services.

The Company competes for loans principally through the range and
quality of the services it provides, interest rates and loan fees. The Company
believes that its long-standing presence in the community and personal service
philosophy enhances its ability to compete favorably in attracting and retaining
individual and business customers. The Company actively solicits deposit-related
clients and competes for deposits by offering customers personal attention,
professional service and competitive interest rates.

Old Second Bank's primary market area is Aurora, Illinois, and its
surrounding communities. The city of Aurora is located in northeastern Illinois,
approximately 40 miles west of Chicago. Strategically situated on U.S.
Interstate 88 (the East-West Tollway), Aurora is near the center of the four
county area comprised of DuPage, Kane, Kendall and Will counties. Based upon the
1990 census, these counties together represent a market of more than 1.4 million
people. The city of Aurora has a current reported population of approximately
120,000 residents.

The banks offer banking services for retail, commercial, industrial,
and public entity customers in the Aurora, Maple Park, Kaneville, North Aurora,
Yorkville, Plano, Ottawa, Burlington, Elburn, Wasco and Sugar Grove communities
and surrounding areas. Old Second also offers complete trust and other fiduciary
services to commercial customers and individuals. Non-FDIC insured mutual funds,
stocks, bonds, securities and annuities are provided by LPL Financial Services,
Inc., a registered broker/dealer and member NASD, SIPC.

The Banks are subject to vigorous competition from other banks and
savings and loan associations, as well as credit unions and other financial
institutions in the area. Within the Aurora banking market, which is
geographically covers the southern two-thirds of Kane County and the northern
one-third of Kendall County, there are in excess of 20 other banks.



Page 3
Within the Yorkville National Bank market, which includes portions of Kane and
LaSalle counties and all of Kendall county, there are approximately 10 other
banks or banking facilities and several savings and loan associations.

Since 1992, Maple Park has developed a wholesale (correspondent)
division primarily engaged in soliciting mortgage loans in Iowa, Colorado,
Wyoming and Illinois. The wholesale division emphasizes developing relationships
with financial institutions. Maple Park currently holds contracts with over 300
banks and credit unions. Maple Park operates as a mortgage broker offering a
wide range of products including conventional, fixed and adjustable-rate
mortgages. The New Leaf division of Maple Park is located in St. Charles and
specializes in assisting prospective and current homeowners who do not qualify
in the traditional market to obtain mortgages.

Maple Park faces vigorous competition in all phases of its retail and
correspondent divisions. Competition for its retail products is principally
based on location, convenience, quality and price. Within its retail mortgage
banking market, there are approximately six large companies offering mortgage
banking products and services and a number of small or mid-sized brokerage
operations. Maple Park believes that competition for its correspondent division
is primarily based on convenience, quality and price. There are several large
national companies competing in their correspondent markets.

At December 31, 1999, the Company employed 536 full-time equivalent
employees. The Company places a high priority on staff development, which
involves extensive training, including customer service training. New employees
are selected on the basis of both technical skills and customer service
capabilities. None of the Company's employees are covered by a collective
bargaining agreement with the Company. The Company offers a variety of employee
benefits and management considers its employee relations to be excellent.

SUPERVISION AND REGULATION

Financial institutions and their holding companies are extensively
regulated under federal and state law. As a result, the growth and earnings
performance of the Company can be affected not only by management decisions and
general economic conditions, but also by the requirements of applicable state
and federal statutes and regulations and the policies of various governmental
regulatory authorities, including the Office of the Comptroller of the Currency
(the "OCC"), the Board of Governors of the Federal Reserve System (the "Federal
Reserve"), the Federal Deposit Insurance Company (the "FDIC"), the Illinois
Office of Banks and Real Estate (the "Office"), the Internal Revenue Service and
state taxing authorities and the Securities and Exchange Commission (the "SEC").
The effect of applicable statutes, regulations and regulatory policies can be
significant, and cannot be predicted with a high degree of certainty.

As a bank holding company, the Company is registered with, and is
subject to regulation by, the Federal Reserve under the Bank Holding Company
Act, as amended (the "BHCA"). In accordance with Federal Reserve policy, the
Company is expected to act as a source of financial strength to the Bank and to
commit resources to support the Bank in circumstances where the Company might
not otherwise do so. Under the BHCA, the Company is subject to periodic
examination by the Federal Reserve. The Company is also required to file with
the Federal Reserve periodic reports of the Company's operations and such
additional information regarding the Company and its subsidiary as the Federal
Reserve may require.

Under the BHCA, a bank holding company must obtain Federal Reserve
approval before: (i) acquiring, directly or indirectly, ownership or control of
any voting shares of another bank or bank holding company if, after the
acquisition, it would own or control more than 5% of the shares of the other
bank or bank holding company (unless it already owns or controls the majority of
such shares); (ii) acquiring all or substantially all of the assets of another
bank; or (iii) merging or consolidating with another bank holding company.
Subject to certain conditions (including certain deposit concentration limits
established by the BHCA), the Federal Reserve may allow a bank holding company
to acquire banks located in any state of the United States without regard to
whether the acquisition is prohibited by the law of the state in which the
target bank is located. In approving interstate acquisitions, however, the
Federal Reserve is required to give effect to applicable state law limitations
on the aggregate amount of deposits that may be held by the acquiring bank
holding company and its insured depository institution affiliates in the state
in which the target bank is located (provided that those limits do not
discriminate against out-of-state depository institutions or their holding
companies) and state laws which require that the target bank have been in
existence for a minimum period of time (not to exceed five years) before being
acquired by an out-of-state bank holding company.

The BHCA also generally prohibits the Company from acquiring direct or
indirect ownership or control of more than 5% of the voting shares of any
company which is not a bank and from engaging in any business other than that of
banking,



Page 4
managing and controlling banks or furnishing services to banks and their
subsidiaries. This general prohibition is subject to a number of exceptions. The
principal exception allows bank holding companies to engage in, and to own
shares of companies engaged in, certain businesses found by the Federal Reserve
to be "so closely related to banking ... as to be a proper incident thereto."
Under current regulations of the Federal Reserve, bank holding companies and
their non-bank subsidiaries are permitted to engage in a variety of
banking-related businesses, including the operation of a thrift, sales and
consumer finance, equipment leasing, the operation of a computer service bureau
(including software development), and mortgage banking and brokerage. The BHCA
generally does not place territorial restrictions on the domestic activities of
non-bank subsidiaries of bank holding companies.

Federal law also prohibits any person or company from acquiring
"control" of a bank or a bank holding company without prior notice to the
appropriate federal bank regulator. "Control" is defined in certain cases as the
acquisition of 10% of the outstanding shares of a bank or bank holding company.

The Illinois Bank Holding Company Act permits Illinois bank holding
companies to acquire control of banks in any state and permits bank holding
companies whose principal place of business is in another state to acquire
control of Illinois banks or bank holding companies upon satisfactory
application to the Illinois office of Banks and Real Estate.

Under the Illinois Banking Act (the "IBA") and the National Bank Act
impose limitations on the amount of dividends that may be paid by banks.
Generally, a bank may pay dividends out of its undivided profits, in such
amounts and at such time as the bank's board of directors deems prudent. Without
prior approval, however, a bank may not pay dividends in any calendar year
which, in the aggregate, exceed the bank's year-to-date net income plus the
bank's retained net income for the two preceding years.

The payment of dividends by any financial institution or its holding
company is affected by the requirement to maintain adequate capital pursuant to
applicable capital adequacy guidelines and regulations, and a financial
institution generally is prohibited from paying any dividends if, following
payment thereof, the institution would be undercapitalized. As described above,
the Bank exceeded its minimum capital requirements under applicable guidelines
as of December 31, 1999. As of December 31, 1999, approximately $10.8 million
was available to be paid as dividends to the Company by the Bank.
Notwithstanding the availability of funds for dividends, however, banking
regulators may prohibit the payment of any dividends by the Bank if it is
determined that such payment would constitute an unsafe or unsound practice.

Federal banking regulators require banks and bank holding companies to
maintain minimum levels of capital. If capital falls below minimum guideline
levels, a bank holding company, among other things, may be denied approval to
acquire or establish additional banks or non-bank businesses.

The capital guidelines establish the following minimum regulatory
capital requirements: a risk-based requirement expressed as a percentage of
total risk-weighted assets, and a leverage requirement expressed as a percentage
of total assets. The risk-based requirement consists of a minimum ratio of total
capital to total risk-weighted assets of 8%, at least one-half of which must be
Tier 1 capital. The leverage requirement consists of a minimum ratio of Tier 1
capital to total assets of 3% for the most highly rated companies, with a
minimum requirement of 4% for all others. For purposes of these capital
standards, Tier 1 capital consists primarily of permanent stockholders' equity
less intangible assets (other than certain mortgage servicing rights and
purchased credit card relationships). Total capital consists primarily of Tier 1
capital plus certain other debt and equity instruments which do not qualify as
Tier 1 capital and a portion of the Company's allowance for loan and lease
losses.

The risk-based and leverage standards described above are minimum
requirements. Higher capital levels will be required if warranted by the
particular circumstances or risk profiles of individual banking organizations.
For example, the capital guidelines contemplate that additional capital may be
required to take adequate account of, among other things, interest rate risk, or
the risks posed by concentrations of credit, nontraditional activities or
securities trading activities. Further, any banking organization experiencing or
anticipating significant growth would be expected to maintain capital ratios,
including tangible capital positions (i.e., Tier 1 capital less all intangible
assets), well above the minimum levels.

As of December 31, 1999, the Company had regulatory capital in excess
of the Federal Reserve's minimum requirements, with a risk-based capital ratio
of 14.61% and a leverage ratio of 10.17%.

The Delaware General Company Law (the "DGCL") allows the Company to pay
dividends only out of its surplus (as



Page 5
defined and computed in accordance with the provisions of the DGCL) or if the
Company has no such surplus, out of its net profits for the fiscal year in which
the dividend is declared and/or the preceding fiscal year. Additionally, the
Federal Reserve has issued a policy statement with regard to the payment of cash
dividends by bank holding companies. The policy statement provides that a bank
holding company should not pay cash dividends which exceed its net income or
which can only be funded in ways that weaken the bank holding company's
financial health, such as by borrowing. The Federal Reserve also possesses
enforcement powers over bank holding companies and their non-bank subsidiaries
to prevent or remedy actions that represent unsafe or unsound practices or
violations of applicable statutes and regulations. Among these powers is the
ability to proscribe the payment of dividends by banks and bank holding
companies.

The Company's common stock is registered with the SEC under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). Consequently,
the Company is subject to the information, proxy solicitation, insider trading
and other restrictions and requirements of the SEC under the Exchange Act.

As FDIC-insured institutions, the banks are required to pay deposit
insurance premium assessments to the FDIC. The FDIC has adopted a risk-based
assessment system under which all insured depository institutions are placed
into one of nine categories and assessed insurance premiums based upon their
respective levels of capital and results of supervisory evaluations.
Institutions classified as well-capitalized (as defined by the FDIC) and
considered healthy pay the lowest premium while institutions that are less than
adequately capitalized (as defined by the FDIC) and considered of substantial
supervisory concern pay the highest premium. Risk classification of all insured
institutions is made by the FDIC for each semi-annual assessment period.

The FDIC may terminate the deposit insurance of any insured depository
institution if the FDIC determines, after a hearing, that the institution (i)
has engaged or is engaging in unsafe or unsound practices, (ii) is in an unsafe
or unsound condition to continue operations or (iii) has violated any applicable
law, regulation, order, or any condition imposed in writing by, or written
agreement with, the FDIC. The FDIC may also suspend deposit insurance
temporarily during the hearing process for a permanent termination of insurance
if the institution has no tangible capital. Management of the Company is not
aware of any activity or condition that could result in termination of the
deposit insurance of the Bank.

Federal law provides the federal banking regulators with broad power to
take prompt corrective action to resolve the problems of undercapitalized
institutions. The extent of the regulators' powers depends on whether the
institution in question is "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" or "critically
undercapitalized," in each case as defined by regulation. Depending upon the
capital category to which an institution is assigned, the regulators' corrective
powers include: requiring the institution to submit a capital restoration plan;
limiting the institution's asset growth and restricting its activities;
requiring the institution to issue additional capital stock (including
additional voting stock) or to be acquired; restricting transactions between the
institution and its affiliates; restricting the interest rate the institution
may pay on deposits; ordering a new election of directors of the institution;
requiring that senior executive officers or directors be dismissed; prohibiting
the institution from accepting deposits from correspondent banks; requiring the
institution to divest certain subsidiaries; prohibiting the payment of principal
or interest on subordinated debt; and ultimately, appointing a receiver for the
institution. As of December 31, 1999, the Company and the banks were well
capitalized.

National banks headquartered in Illinois, such as the Bank, have the
same branching rights in Illinois as banks chartered under Illinois law.
Illinois law grants Illinois-chartered banks the authority to establish branches
anywhere in the State of Illinois, subject to receipt of all required regulatory
approvals.

Under the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 (the "Riegle-Neal Act"), both state and national banks are allowed to
establish interstate branch networks through acquisitions of other banks,
subject to certain conditions, including certain limitations on the aggregate
amount of deposits that may be held by the surviving bank and all of its insured
depository institution affiliates. The establishment of new interstate branches
or the acquisition of individual branches of a bank in another state (rather
than the acquisition of an out-of-state bank in its entirety) is allowed by the
Riegle-Neal Act only if specifically authorized by state law. The legislation
allowed individual states to "opt-out" of certain provisions of the Riegle-Neal
Act by enacting appropriate legislation prior to June 1, 1997. Illinois has
enacted legislation permitting interstate mergers beginning on June 1, 1997,
subject to certain conditions, including a prohibition against interstate
mergers involving an Illinois bank that has been in existence and continuous
operation for fewer than five years.


Page 6
Federal Reserve regulations, as presently in effect, require depository
institutions to maintain non-interest earning reserves against their transaction
accounts (primarily NOW and regular checking accounts), as follows: for
transaction accounts aggregating $39.3 million or less, the reserve requirement
is 3% of total transaction accounts; and for transaction accounts aggregating in
excess of $39.3 million, the reserve requirement is $1.179 million plus 10% of
the aggregate amount of total transaction accounts in excess of $39.3 million.
The first $5.0 million of otherwise reservable balances are exempted from the
reserve requirements. These reserve requirements are subject to annual
adjustment by the Federal Reserve. The Bank is in compliance with the foregoing
requirements.

Total nonperforming assets $ 2,119 $ 2,695 $ 3,804 $ 4,253 $ 4,936
=========== =========== =========== =========== ===========

Accrual of interest is discontinued on a loan when principal or interest is
ninety days or more past due, unless the loan is well secured and in the process
of collection. When a loan is placed on nonaccrual status, interest previously
accrued but not collected in the current period is reversed against current
period interest income. Interest accrued in prior years but not collected is
charged against the allowance for loan losses. Interest income of approximately
$50,000, $23,000, and $84,000 was recorded during 1999, 1998, and 1997, on loans
in nonaccrual status at year-end. Interest income which would have been
recognized during 1999, 1998, and 1997, had these loans been on an accrual basis
throughout the year, was approximately $142,000, $114,000, and $273,000.

The following table summarizes, for the years indicated, activity in the
allowance for loan losses, including amounts charged off, amounts of recoveries,
additions to the allowance charged to operating expense, and the ratio of net
charge-offs to average loans outstanding:

</TABLE>

The provision for loan losses is based upon management's estimate of anticipated
loan losses and its evaluation of the adequacy of the allowance for loan losses.
Factors which influence management's judgement in estimating loan losses are the
composition of the portfolio, past loss experience, loan delinquencies,
nonperforming loans, and other factors that, in management's judgment, deserve
evaluation in estimating loan losses.
