the Corporation had seven subsidiary banks, as follows:  
Old Second, The Old Second Community Bank of North Aurora, The
Old Second Community Bank of Aurora, The Yorkville National Bank,

The banks are subject to vigorous competition from other banks

Within the Aurora banking market, which is approximated 
by the southern two-thirds of Kane County and the northern one-
third of Kendall County, there are in excess of 20 other
banks. 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.

believes that 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.

Interest Rate Repricing Gaps

Interest rate sensitive assets and liabilities are those which
have yields or rates subject to change within a future time
period due to maturity or changes in market rates. The
Corporation's exposure to interest rate risk is managed primarily
through the  Corporation's strategy of selecting types and terms
of interest-earning assets and interest-bearing liabilities which
generate favorable earnings while limiting the potential negative
effects of  changes in market rates.
  
The Corporation monitors rate sensitive assets and liabilities by
positioning amounts into periods based upon contractual terms,
historical experience or frequency of repricing. An asset
sensitive position in a given period will result in more assets
than liabilities being subject to repricing; therefore, market
rate changes will be reflected more quickly in asset rates. If
interest rates decline, such a position will have an adverse
affect on net interest income. Conversely, in a liability
sensitive position, where liabilities reprice more quickly than
assets in a given period, a decline in market rates will benefit
net interest income. Since rate sensitive assets and liabilities
do not  respond in the same manner to changing markets, the
theory noted herein should not be used as the sole indicator of
how the Corporation would be affected by changes in interest
rates.  Following are the amounts, in thousands of dollars, of
the rate sensitive assets and liabilities positioned into periods
based upon repricing as of December 31,1998.

Risk Elements        

Nonaccrual, past due and restructured loans include,
respectively, loans on which no interest is currently being 
accrued, accruing loans which are past due 90 days or more as to
principal or interest payments, and loans neither in nonaccrual
status nor 90 day delinquent status on which the terms of
maturity or interest rate have been renegotiated 
to provide a reduction or deferral of interest or principal
payments due to a deterioration in the financial position 
of the borrower. It is management's general policy to discontinue
the accrual of interest on a loan when it is past due 
90 days with regard to either interest or principal payments.  At
any given date,  The Corporation's subsidiaries may have 
various loans outstanding, which are accruing interest, are not
contractually past due more than 90 days, and are not
renegotiated, but which, in management's opinion, may not be
repaid according to original terms; these are shown 
below as "potential loan problems".  Management periodically
reviews these accounts which are currently in its 
portfolio and is of the opinion that, although some restructuring
of loan terms may be required, no material loss of 
principal will occur.
    
The following is a summary of loans described above at the dates
indicated, in thousands of dollars:

(1)Loans in this category represent those which have been
periodically delinquent as to the payment of principal and 
interest and are vulnerable to adverse economic conditions.  The
collateral position of the Corporation's subsidiaries 
on these loans mitigates the amount of loss exposure when viewed
in their entirety. There were no foreign 
outstandings or loan concentrations at the dates indicated.

Credit Quality Management and the Allowance for Loan Losses

The corporation  monitors its credit risk using established
formal credit polices and procedures which are monitored and
modified on an ongoing basis.  The allowance for loan losses is
determined using 1) Specific Allocations, 2) General Risk
Allocations and 3) a Minimum Allowance Amount.  The total of
specific and general risk allocations must be equal to or greater
than the minimum allowance amount.

Specific Allocations:

     Individual loans are analyzed quarterly to determine an
     amount which represents the maximum, minimum and most likely
     amounts of possible loss exposure and to determine any
     immediate charge-offs.  Loans which are analyzed include any
     commercial and real estate loan which is classified in one
     or more of the following categories:
     
          Loans classified by examiners.

          Loans rated below an established departmental rating.
     
          All loans in claims and judgments.
     
          Any real estate loan more than three payments past due.

          Any loan on non-accrual.
 .
          Any short term loan delinquent more than 30 days past
          its maturity.

          Any commercial loan more than two payments past its
          payment due date.

          Any loan in which the loan officer considers the credit
          to be a problem.

          Certain other loans as determined by senior loan
          officers to be a problem.

          Certain classes of loans or concentrations of credits
          as determined by senior management.

These loans are analyzed on a quarterly basis by the individual
loan officers with results reported to the Loan Review Committee. 

Other loans reported to the loan review committee include loans
that  may have some potential for repayment problems but are not
immediate collection problems and are placed on the Bank's watch
list. Loans are considered impaired when it is probable that the
bank will be unable to collect the contractual amount of both
principal and interest. 

General Risk Allocation:

     Under this category, an analysis is made quarterly based on
     consideration of the following factors:

     Historical Net Loss Experience:
     An average of the net charge-offs in the Consumer Credit,
     Commercial and Real Estate loan areas is calculated for five
     years on a rolling quarterly basis.  Recent year loss
     experiences are more heavily weighted to account for 35% of
     the loss average, year 2 - 25%, year 3 - 15%, year 4 - 15%
     and year 5 - 10%.

     Off-Balance Sheet Risk:
     Off-balance sheet risks such as Letters of Credit and
     commitments outstanding on lines of credit are multiplied by
     a percentage established by management.

     Volume and Trends in Delinquencies and Non-Accruals:
     In order to account for additional risk associated with
     delinquent loans and to adjust for recent trends in
     delinquent loans more than 30 days past due or non-accrual
     loans not on the problem or watch list are reviewed by
     management.  The net balance of these loans is multiplied by
     a percentage determined by management, and the resulting
     amount is added to the allowance.






                         Page 12 of 54

<PAGE>






Minimum Allowance Amount: 

     Management has determined that the amount of the allowance
     should not be less than 1.25% of the total outstanding loan
     balance.  Monthly amounts as determined by senior management
     will be placed into the allowance in order to maintain this
     percentage.  Should charge-offs be incurred which cause the
     allowance to fall below this amount, additional accruals
     will immediately be recorded to maintain this balance.
     
     A summary of this allowance determination, the list of
     problem loans and watch loans and their respective
     allocation of the allowance for loan losses is reported to
     the loan committee of the Board of Directors on a monthly
     basis.  During this review, should a loan be determined to
     have some loss, this amount will be charged-off immediately.
                                 
     The factors that attribute to the changes in the elements
     and components of the allowance for loan losses from
     December 31,1997, to December 31,1998, are as follows: 
 
There have been no changes in lending policy or procedures during
the last 12 months which would have an impact on the allowance.

There have been no changes in lending management or staff which
would warrant an adjustment level of the allowance for loan loss.

Management believes that in assessing economic and business
conditions and developments that we are near the top of the
economic cycle. We have allocated a loss percentage based on the
outstanding risk associated with the portfolio.  The portfolio
risk was adjusted with each loan review and quarterly credit
management review.  The allowance for loss associated with each
risk category was adjusted based on economic trends and
prevailing business conditions.

Changes in the nature and volume of the portfolio have been
moderate over the last year.  The level of loan growth does not
have an impact on the allowance at this time.

The volume of past due loans has been higher since the
acquisition of Maple Park  Bancshares, Inc.  This has been
considered in the allowance calculation and management believes
the trend will reverse in time due to the installation of
additional management at that institution.

There have been no changes in the loan review system or in the
quality of the Board oversight this year. 

There is a concentration of credit with real estate developers
and agricultural related entities.  The real estate and 
agricultural loans were individually reviewed in the fourth
quarter of 1998 and there is no need to adjust the allowance for
loan loss as a result of this concentration.

Letter To Stockholders


To Our Stockholders:
     

     The conclusion of 1998 marks
the beginning of a new era for
your company.  Old Second Bancorp
ended the year with total assets
of over $1 billion. As we
approach the Millennium, we do so
as a strongly capitalized,
billion dollar asset organization
with a quality loan portfolio,
strong core deposits, a growing
area within which we operate, and
a flavor for maintaining a
community banking atmosphere.  
     

     We are proud of our records
achieved at Old Second Bancorp
this year. Through the efforts of
our management and staff at the
holding company as well as at our
various banks and mortgage
company, we performed at record
levels in 1998:      

  *Total assets were at a record
level of 
    $1,014,292,000  
  *Total net earnings were
$11,049,000 - a 15.2%
     increase over 1997   
  *Total stockholders' equity at
year end was at an  
    all time high - $101,926,000  
                       
  *Cash dividends declared
increased for the thirty-         
      second consecutive year
(cash dividends are  
    currently $0.25 per quarter) 
  *Return on equity was at 11.7%
  *Return on assets was at 1.15%
  *Basic earnings per share
increased to $3.62
     from $3.15 in 1997
  *Trades of stock as quoted by
NASDAQ were
     at $53.00 per share at year
end


     Our Trust Department had
another exceptional year with
assets under management of
approximately $600,000,000. 
Gross and net trust fees were at
record levels. The trust office
at Elburn was consolidated into
the trust office at Geneva during
1998, to improve efficiency and
provide higher quality services
to our customers.
     
     Continued growth of our
Yorkville National Bank's branch
in Ottawa required us to expand
our physical plant at that
location. A new 6,000 square foot
building is scheduled for
completion in March 1999 at the
same location on Route #71 in
Ottawa. We believe this
investment will be rewarded with
continued strong growth and
profits.

     Maple Park Mortgage, a wholly
owned subsidiary of Old Second
Bancorp, generated significant  net
income. A new office was opened in
Wheaton to add to existing offices
in St. Charles, Sycamore,
Bannockburn and Oswego. We look
forward to continued growth and
additional fee income from this
company. 
     

     We continue to monitor our
costs and efficiencies in all
areas. As of January 1, 1999 in an
attempt to become more efficient,
we consolidated Old Second
Community Bank of North Aurora and
Old Second Community Bank of Aurora
into Old Second  National Bank of
Aurora. These two locations will be
operated as branches and our goal
is to have decision makers at each
location so that they will operate
as they have in the past but with
lower costs.

     
     Old Second Bancorp has spent a
considerable amount of resources
the past several years to make sure
that Year 2000 potential problems
are properly addressed. All
critical applications are now  Year
2000 compliant and we are in the
process of testing these
applications on an integrated 
basis. This testing should be
completed by March 1999. Bancorp
management feels that we have made
excellent progress in this area and
every effort will be made to ensure
that we do not have any operating
difficulties as we enter the next
century.
     

     Your company is meeting the
financial needs of people
throughout the southern Fox Valley
region with 17 locations, 2 trust
offices and 5 mortgage offices. We
also continue our expansion of
electronic banking by providing
corporate cash management, personal
home computer banking and, of
course, debit and credit cards.
Check imaging was successfully
introduced to our  customers within
the 4th quarter of 1998; the
acceptance of this change has been
most  gratifying. A Bancorp
Internet Website is in the process
of being developed and should be 
available in the first quarter of
1999.
     
     The financial success of our
Bank is the outcome of 
professional management of our
assets and liabilities, development
of new business and the careful
nurturing of our existing
customers. Lending and deposit

rate structures are managed
carefully to provide fair,
competitive rates to our customers. 
Prices on services are continually
monitored in an effort to ensure
that we are competitive and we
receive adequate cost recovery and
profit. Excess funds are prudently
invested in  marketable securities.
      Community involvement of all
of our banks and branches is a
philosophy that has been our policy
for decades. Hundreds of hours of
volunteer time has been provided by
our officers and staff to the
communities in which they are
located. We believe this philosophy
of giving and sharing is of mutual
benefit to the markets that we
serve. 
     We are committed to preparing
for a profitable future through
improvement and expansion of our 
business. We are ever thankful of
our loyal staff, our customers, our
Board of Directors and to you, our
stockholders.
                                    
               
       Sincerely,

       James Benson

       Chairman

       William B. Skoglund

       President & CEO

 Management's Discussion

Management's Discussion & Analysis
                                    
                                
The consolidated financial
statements include the accounts of
Old Second Bancorp, Inc. (the
Corporation) and its subsidiaries,
all of which are wholly owned. The
financial statements have been
prepared in conformity with
generally accepted accounting
principles and reporting practices
that are applied in the banking
industry. 

During 1998, in an effort to
improve operational efficiencies,
the Board agreed to make the Old
Second Community Bank of Aurora and
the Old Second Community Bank of
North Aurora branches of Old Second
National Bank.  Management plans on
having decision makers at the
Farnsworth and North Aurora
locations and to operate these
offices as in the past. With these
mergers which occurred on January
1, 1999, the Corporation remains a
multi-bank holding company with
seventeen full-service bank
facilities, two trust locations and
five mortgage banking offices.

Performance Summary
                                    
                                
Net income of $11.0 million or
$3.62 per share for 1998 increased
$1.5 million or 15.2% from 1997
following a gain of $1.3 million,
15.1%, in 1997 over 1996. For the
year, returns on average assets and
equity were 1.15% and 11.7%
respectively, up from 1.06% and
11.0% in 1997. 
Total assets grew $66 million or
7.0% from year end 1997 to slightly
over $1 billion at December 31,
1998.

Results of Operations

 Net interest income                
                          
Net interest income for 1998 of
$35.9 million was up $1.8 million
from 1997 following an increase of
$2.2 million in 1997 over 1996. The
increase was primarily due to
higher average interest earning
assets which were up 7.3% in 1998
from 1997 and 9.2% in 1997 from
1996. The tax equivalent net
interest margin defined as tax
equivalent net interest income
divided by average interest earning
assets for 1998, 1997 and 1996
respectively was 4.14%, 4.23% and
4.35%. 


Provision for loan losses
The provision for loan losses for
both 1998 and 1997 was 
approximately $1.2 million and 
$748,000 in 1996. The subsidiaries
realized net loan charge-offs of
$313,000 in 1998 with net charge
offs reported  as $1.3 million and
$466,000 in 1997 and 1996
respectively. As of December 31,
1998, the allowance for loan losses
was $7.8 million or 1.41% of gross
loans and 292% of nonperforming
loans. These amounts and ratios
were $6.9 million, 1.29% and 188%,
respectively, at year end 1997.
Management's quarterly review of
the adequacy of the allowance for
loan losses and the amount of the
provision for loan losses is based
on various factors, such as the
nature and volume of the loan
portfolio, historical loss
experience and changes in economic
conditions.                         
 <PAGE>
Non-interest income
Total other income for 1998 of $20.4
million was $6.4 million over 1997
which was substantially the same as
1996. Of the gain in 1998, $6.3
million was related to mortgage
banking activities which included
secondary mortgage fees, mortgage
servicing income and gain on sale of
loans.  Loans sold during 1998 were
approximately $660 million. The
fluctuations in income of  secondary
mortgage fees and gain on sale of
loans correspond to the changing
demands of customers as they take
advantage of refinancing during
periods of declining interest rates.

Trust fees of $4.2 million in 1998
were at record high levels
increasing $237,000 or 6.1% from
1997. Assets under management at
year end 1998 were at record levels
of over $600 million. Trust fees in
1997 of $3.9 million gained 5.6%
from 1996. Service charges on
deposit accounts of $3.1 million
remained relatively unchanged from
1997 which was $227,000 over 1996.

Non-interest expenses
Total other expenses were $39.0,
$33.2 and $33.1 million in 1998,
1997 and 1996 respectively. Total
other expenses as a percent of
average assets were 4.05% in 1998
compared to 3.69% in 1997 and 4.01%
in 1996. The productivity ratio,
defined as net interest income plus
total other income divided by total
other expenses, measures the
effectiveness of the Corporation to
generate  interest and non-interest
income, while controlling costs
necessary to deliver quality 
products and services to customers.
The productivity ratios of 144% and
145% in 1998 and 1997 respectively
showed improvement from 138% in
1996. 

Salaries and employee benefits
during 1998 of $20.7 million were up
$2.7 million from 1997. Of this
increase, $1.8 million related to
salaries based on the volume of
mortgage banking activities.
Salaries and employee benefits
related to core banking operations
increased 6.6% from 1997.

Net occupancy for 1998 of $2.4
million increased $196,000 from 1997
which was $54,000 lower than 1996.
The increase from 1997 was partially
due to new locations and expansion
activities.

Furniture and equipment costs for
1998 are $4.0 million  compared to
$3.3 million for both 1997 and 1996.
The expenses in 1998 include costs
to implement image processing and
upgrades to the mainframe and
personal computer network for year
2000 processing.

Amortization of intangibles was $2.2
million in 1998 up from $1.1 million
in 1997 and $1.5  million in 1996.
During 1998, a provision of $937,000
was recorded to adjust the valuation
of mortgage servicing rights to
their fair market value.  
 
Income taxes
During 1998, the corporation
provided $5.0 million for federal
and state income taxes resulting in
an effective tax rate of 31.3%. The
effective tax rates in 1997 and 1996
were 29.5% and 30.3% respectively.

Management's Discussion - Continued

Financial Condition                  
                        
                                     
                               
At December 31, 1998, total assets
of slightly over $1 billion were
$65.9 million or 7.0% higher than
year end 1997. Gross loans of $556.5
million, excluding loans held for
sale, were up $21.9 million for a
total of 4.1% while deposits of
$826.3 million increased by $37.4
million or 4.7%.

 Investments                         
                         
Investment securities represented
28.5% of average interest earning
assets during 1998 down from 32.0%
during 1997. At December 31, 1998,
investment securities were up $27.9
million from year end 1997 to $292.4
million. The portfolio has shifted
toward investments in agency
securities which represented 62.2%
of the total at December 31, 1998
compared to 54.6% at year end 1997.

 Loans
Throughout 1998, the Fox Valley area
continued to grow with strong
housing and business development
increasing the demand for
residential and commercial
mortgages. The loan portfolio
generally reflects the profile of
the communities in which the
Corporation operates. The
percentages of construction real
estate and installment loans to
gross loans of 8.3% and 10.3%
respectively in 1998 were relatively
unchanged from 1997. Commercial,
financial and agricultural loans
represented 25.7% of gross loans at
year end 1998, down from 27.4% in
1997. The percentage of real estate
mortgage loans to gross loans
increased to 55.7% at  year end
1998, up from 53.7%. At December 31,
1998, real estate mortgage loans
were $309.9 million, an increase of
$22.7 million or 7.9%.

Sources of funds
The Corporation relies primarily on
customers' deposits, securities sold
under repurchase agreements and
other borrowings along with
stockholders' equity to fund its
earning assets. During  1998, the
mix of interest bearing deposits
shifted to NOW and money market
accounts from certificates of
deposits under $100,000. At December
31, 1998, NOW and money market
accounts  represented 31.2% of total
deposits compared to 25.5% at year
end 1997. Certificates of deposits
less than $100,000 were 32.3% and
37.8% of total deposits for year end
1998 and 1997 respectively. 

Securities sold under repurchase
agreements were $32.6 million at
December 31, 1998, an increase of
$9.7 million over 1997. A note
payable of $36.2 million year end
1998 relates to a line of credit
used by Maple Park  Mortgage to fund
residential mortgages held for sale.

Capital and Dividends

 The Corporation continues to
maintain a strong capital position
which supports its current needs and
provides a sound foundation for
future expansion. Total
stockholders' equity of $101.9
million  increased $9.8 million from
1997 and represented 
<PAGE>

10.0% of total assets at year end
1998. Book value per share increased
10.6% from year end 1997 to $33.41
at December 31, 1998.

Dividends paid during 1998 were 
$0.95 per share, an increase of 6.7%
from $0.89 in 1997. The dividend
payout ratios were 24.9% and 28.3%
for 1998 and 1997 respectively. The
regular quarterly dividend per share
was increased 25% to $0.25 in the
third and fourth quarters of 1998.
Bank regulatory authorities
established risk-based capital
guidelines including minimum capital
requirements and are further
discussed in Note Q - Regulatory
Matters. At December 31, 1998, the
minimum total and tier 1 capital
ratios were 8.0% and 4.0%
respectively. The Corporation's
total and tier 1 capital ratios were
15.5% and  14.3% respectively at
year end 1998.

Liquidity

Liquidity is generally defined as
the Corporation's ability to meet
depositor withdrawal requests,
provide for acceptable credit needs
of customers and take advantage of
earnings enhancement  opportunities.
The Corporation has provided for
liquidity needs by holding adequate
balances in money market assets and
maintaining various short-term
borrowing sources combined with
normal growth in core deposits and
maturities of loans and investments. 

As of December 31, 1998, federal
funds sold and investment securities
maturing within 30 days were $65.5
million or 6.5% of total  assets. 
Additionally, unpledged  investment
securities not maturing within 30
days were $190 million or 18.8% of
total assets.

The parent company's liquidity
provides funds for the payment of
dividends to stockholders and for
other corporate purposes. The cash
requirements of the parent company
have been met by dividends from its
subsidiaries. Management believes
that funds available from
subsidiaries, which are  described
in Note P- Dividend Limitation, are
sufficient to meet future cash
needs.

Interest Rate Risk

 Interest rate sensitive assets and
liabilities are those which have
yields or rates subject to change
within a future time period due to
maturity or changes in market rates.
The Corporation's exposure to
interest rate risk is managed
primarily through the  Corporation's
strategy of selecting types and
terms of interest-earning assets and
interest-bearing liabilities which
generate favorable earnings while
limiting the potential negative
effects of  changes in market rates.

The Corporation monitors rate
sensitive assets and liabilities by
positioning amounts into periods
based upon contractual terms,
historical experience or frequency
of repricing. An asset sensitive
position in a given period will
result in more assets than
liabilities being subject to
repricing; therefore, market rate
changes will be

Page 5

Page 28 of 54


reflected more quickly in asset
rates. If interest rates decline,
such a position will have an adverse
affect on net interest income.
Conversely, in a liability sensitive
position, where liabilities reprice
more quickly than assets in a given
period, a decline in market rates
will benefit net interest income.
Since rate sensitive assets and
liabilities do not  respond in the
same manner to changing markets, the
theory noted herein should not be
used as the sole indicator of how
the Corporation would be affected by
changes in interest rates.

The Corporation has set specific
guidelines to manage its cumulative
gap position. The Corporation can
manage its gap position by
shortening loan maturities, pricing
loans with  variable rates,
purchasing short-term investment
securities or attracting longer term
certificates of deposits. The effect
on earnings and capital would be
considered when making decisions to
manage the gap position. The
following table(opposite page)sets forth the
scheduled  maturity of the
Corporation's rate sensitive assets
and liabilities at December 31,
1998.

Impact of Year 2000                  
                        

The Corporation is currently in  the
process of addressing a potential
problem that faces  all users of
automated systems including
information systems. Many computer
systems process transactions based
on two digits representing the year
of transaction, rather than a full
four digits. These computer systems
may not operate properly when the
last two digits become "00", as will 
occur on January 1, 2000. The
problem could effect a wide variety
of automated information systems,
such as mainframe applications,
personal computers, communications
and environmental systems.

 The Corporation has identified
areas of operations critical for the
delivery of its products and
services. The majority of the
programs and applications used in
the Corporation's operations are 
purchased from outside vendors. The
vendors providing the software are
responsible for maintenance and
modifications of these systems to
enable uninterrupted usage after
December 31, 1999.

The Corporation's plan included
identifying potential problems by
performing an inventory of  all
software applications and obtaining
certification of compliance from
third parties. This phase of the
plan was completed by December 31,
1998. The vendor of the
Corporation's core operating system
has provided certification of
compliance with the year 2000 issue
and testing of the core operating
system was completed during 1998.
Contingency plans and testing of
other affected  applications are
expected to be completed by March
1999. The Corporation's plan also
includes reviewing any  potential
risks associated with the loan and
investment portfolios due to the
year 2000 issue.

 As noted above, the Corporation has
not yet completed all phases of its
plan to address year 2000 issues.
Since certification

<PAGE>
 

and testing of the core operating
system was completed during 1998,
management believes that core
business services can be delivered
without interruption after  December
31, 1999. In the event that core
services cannot be delivered, the 
Corporation could be subject to
litigation and the amount of
potential liability cannot be
reasonably estimated.

The Corporation believes that all
costs to address year 2000 issues
were incurred during 1998. These
costs were not considered to be
material. Therefore, unanticipated
future costs should not have a
materially adverse impact on  the
Corporation's financial condition or
results of operations.

Effects of Inflation

Inflation can have a significant
effect on the operating results of
all industries. Management believes
that inflationary factors are not as
critical to the banking industry
relative to other  industries.
Management closely monitors
operating expenses and adjusts the
pricing of services in view of
inflationary increases and market
competition. Inflation significantly
impacts interest rates but it is
difficult to access the timing and
magnitude of changes in response to
inflation indices. Inflation does
impact the value of longer term rate
sensitive assets and liabilities;
consequently, the Corporation limits
its holding of these types of assets
and liabilities.

New Accounting Pronouncements
      
As of January 1, 1998, the
Corporation adopted Statement of
Financial Accounting Standards
(SFAS) No. 130 "Reporting
Comprehensive Income." SFAS No. 130
establishes new rules for the 
reporting and display of
comprehensive income and its
components; however, the adoption of
this Statement had no impact on the
Corporation's net income or
stockholders' equity. SFAS No. 130
requires unrealized gains or losses
on the Corporation's
available-for-sale securities, which
prior to adoption were reported
separately in stockholders' equity,
to be included in other
comprehensive  income. Prior year
financial statements have been
reclassified to conform to the
requirements of SFAS No. 130.

During 1998, the Corporation adoped
SFAS No. 132, "Employers'
Disclosures about  Pensions and
Other Post-retirement Benefits"
which is designed to improve and
standardize disclosures about  
pension and other post-retirement
benefits. Adoption did not have a
material effect on the 
Corporation's financial position or
results of operations.

In June 1998, the Financial
Accounting Standards Board issued
SFAS No. 133, "Accounting for
Derivative Instruments and Hedging
Activities", which is required to be
adopted in years beginning after
June 15, 1999. Because of the
Corporation's minimal use of
derivatives, management does not
anticipate that the adoption will
have a significant effect on
earnings or the financial position
of the Corporation.

Notes to Consolidated Financial Statements

Old Second Bancorp, Inc. and Subsidiaries

Note A - Summary of significant accounting policies
The accounting and reporting policies of Old Second Bancorp, Inc.
(the Corporation) and its subsidiaries conform
to generally accepted accounting principles and to general
practice within the banking industry. Certain 1997 and
1996 amounts have been reclassified to conform to the 1998
presentation. The following is a description of the
more significant of these policies:

Consolidation
The consolidated financial statements include the accounts of Old
Second Bancorp, Inc. and its wholly-owned
subsidiaries: The Old Second National Bank of Aurora, The Old
Second Community Bank of North Aurora, The Old
Second Community Bank of Aurora, Yorkville National Bank,
Burlington Bank, Kane County Bank and Trust, Bank of
Sugar Grove and Maple Park Mortgage Company. All significant
intercompany balances and transactions have been
eliminated in  consolidation.

The Corporation is a multi-bank holding company, principally
engaged in the business of attracting deposits and
investing these funds, together with borrowings and other funds,
to primarily originate commercial, real estate
and consumer loans, and purchase investment securities. In
addition to the bank subsidiaries, the Corporation has
a mortgage banking subsidiary principally engaged in the business
of originating, purchasing, selling and
servicing residential mortgage loans. The Corporation conducts
its activities from a network of offices in Kane,
Kendall, DeKalb, DuPage, Lake and LaSalle counties.

Use of estimates
The preparation of financial statements in conformity with
generally accepted accounting principles requires
Management to make estimates and assumptions that affect the
amounts reported in the financial statements and
accompanying notes. Actual results could differ from these
estimates.

Cash equivalents
For purposes of reporting cash flows, cash and cash equivalents
include cash on hand, cash due from banks and
federal funds sold. Generally, federal funds are purchased and
sold for one-day  periods.

Investment securities
The Corporation and its subsidiaries generally purchase
securities for investing purposes. Investment securities
are classified in three categories and accounted for as follows:
(1) held-to-maturity - reported at amortized
cost; (2) trading securities - reported at fair value with
unrealized gains and losses included in current
earnings; and (3) available-for-sale securities - reported at
fair value with unrealized gains and losses excluded
from current earnings and included in accumulated other
comprehensive income which is reported as a separate
component of stockholders' equity. Realized gains and losses on
the sale of investment securities are recognized
at the time of the transaction and are determined by the specific
identification method.

Loans held for sale
The Corporation's mortgage subsidiary originates residential real
estate mortgage loans which are sold in the
secondary market, including loans secured under programs with the
Federal Home Loan   Mortgage Corporation
("FHLMC") and the Federal National Mortgage Association ("FNMA").
Mortgage loans held for sale may be hedged with
forward sales commitments in order to minimize interest rate
market exposure by contracting for the sale of loans
in the future at specific prices. Gains and losses from hedging
transactions on residential real estate mortgage
loans held for sale are included in the cost of the loans in
determining the gain or loss when the loans are sold.
Residential real estate mortgage loans held for sale are carried
at the lower of aggregate cost or fair value.

Loans
Interest on installment loans made on a discounted basis is
generally recognized as income using the interest
method. Interest on all other loans is recorded as earned. It is
management's policy to discontinue the accrual of
interest income on any loan when there is reasonable doubt as to
the timely collectibility of interest or
principal.

Allowance for possible loan losses
The allowance for loan losses is increased by provisions charged
to operating expense and decreased by
charge-offs, net of recoveries, and is available for losses
incurred on loans. The provision for loan losses is
computed based on management's judgment as to the adequacy of the
allowance for possible loan losses after
considering such factors as the volume and character of the 
portfolio, general economic conditions and past loan
loss experience. A loan is considered impaired when the carrying
amount of the loan exceeds the present value of
the future cash flows, discounted at the loan's original
effective rate. However, as a practical expedient,
management measures impairment based on the fair value of the
underlying collateral.

Premises and equipment
Premises and equipment are stated at cost less accumulated
depreciation and amortization. Depreciation is computed
over estimated useful lives of ten to forty years for premises
and five to ten years for furniture and equipment
principally by the use of accelerated depreciation methods.
Expenditures for maintenance and repair are expensed
as incurred and expenditures for major  renovations are
capitalized. The cost of property retired or otherwise
disposed of is applied against the related accumulated
depreciation to the extent thereof, and any gain or loss on
disposition is recognized at the time of disposal.

Real estate owned
Real estate owned is initially recorded at the lower of net book
value or fair value, less estimated costs to
sell. The excess of net book value over fair value at the
foreclosure date is charged to the allowance for loan
losses. Subsequent to foreclosure, any gain or loss on
disposition is recognized at the time of disposal.

Trust department revenue
Trust Department income is recorded principally on a cash basis,
which does not result in a material difference
from the accrual basis.

Note A - Summary of significant accounting policies - continued
Retirement plan costs
The Corporation uses the "projected unit credit" actuarial method
for financial reporting purposes and the entry
age cost method for the funding of the qualified plan.

Long-term incentive plan
The Corporation accounts for its Long-Term Plan in accordance
with APB Opinion No. 25,  "Accounting for Stock
Issued to Employees". Under APB Opinion No. 25, as the exercise
price of the Corporation's employees' stock
options equals the market price of the underlying stock on the  
date of grant, no compensation expense is
recognized. The amount of compensation expense which would have
been recorded by the Corporation had it followed
the provisions of SFAS No. 123,  "Accounting for Stock-Based
Compensation", would not have a material effect on
net income per share.

Income taxes
The Corporation  provides for deferred tax assets and liabilities
which represent differences  between financial
reporting and tax bases of assets and liabilities and are
measured using the  enacted tax rates and laws that will
be in effect when the differences are expected to reverse. 
Deferred taxes arise because certain transactions
affect the determination of taxable income for tax  return
purposes. Current tax expense is provided based upon
the actual tax liability incurred for tax return purposes.

Earnings per share
Basic earnings per common share (EPS) is computed by dividing net
income by the weighted average number of common
shares outstanding for the period. The basic EPS calculation
excludes  the dilutive effect of all common stock
equivalents. 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.
The Corporation's potential common shares
represent shares issuable under its stock option plan. Such
common stock equivalents are computed based on the
treasury stock method using the average market price for the
period.

Excess purchase price over fair value of net assets acquired
The excess purchase price paid over the fair value of net assets
acquired is included in other assets and is
amortized into other expenses on a straight-line basis over
fifteen years. This amount is  periodically assessed
to determine if impairment exists.

Financial servicing assets
The Corporation recognizes as separate assets the rights to
service mortgage loans for others. For  purposes of
measuring impairment, the Company stratifies the pools of assets
underlying the  servicing assets by product type
and interest rate. Fair value is estimated by discounting
estimated  future cash flows from the servicing assets
using discount rates that approximate current market rates and
using current expected future prepayment rates. A
valuation allowance is recorded where the fair value is below the
carrying amount of specific stratifications,
even though the overall fair  value of the servicing assets

Segments reporting
Effective January 1, 1998, the Corporation adopted the Financial
Accounting Standards Board's (SFAS) No. 131,
"Disclosures about Segments of an Enterprise and Related
Information." SFAS No. 131 superseded FASB Statement No.
14, "Financial Reporting for Segments of a Business Enterprise."
SFAS No. 131 establishes standards for the way
that public business enterprises report information about
operating segments in annual financial statements and
requires that those  enterprises report selected information
about operating segments in interim financial
reports. SFAS   No. 131 also establishes standards for related
disclosures about products and services, geographic 
areas, and major customers. The adoption of SFAS No. 131 did not
affect results of operations or financial
position. The Corporation has determined that it has one
reportable segment - commercial banking. As such,
additional segment information is not required to be disclosed.
The Corporation offers the following products and
services to external customers: deposits, loans, and trust
services. Revenues for each of these products and
services are disclosed in the Consolidated Statements of Income.

December 31, 1997 and 7.00% at December
31, 1996. The expected long-term rate of return on assets was
8.00% and the assumed rate of increase
in future compensation levels was 4.50% for each of the three
years.

The subsidiaries of the Corporation have contributory and
non-contributory Profit Sharing Plans
covering substantially all of their respective full-time and
regular part-time employees. The amounts
expensed with respect to these Profit Sharing Plans were $737,000
in 1998 and $644,000 in both 1997
and 1996.

Note O - Commitments and contingencies
In the normal course of business, there are outstanding
commitments and contingent liabilities which are not
reflected in the financial statements. Commitments and contingent
liabilities include financial instruments which
involve, to varying degrees, elements of credit, interest rate
and liquidity risk. In the opinion of management,
these do not represent unusual risks for the Corporation's
subsidiaries and management does not anticipate any
significant losses as a result of these transactions. The
Corporation uses the same credit policies in making
commitments and conditional obligations as it does for on-balance
sheet instruments. Standby letters of credit
outstanding at December 31, 1998 are approximately $8.1 million.
Firm commitments by the Corporation's
subsidiaries to fund loans in the future are approximately $257
million as of December 31, 1998. At year end, the
Corporation had commitments to sell loans of $33 million. There
are various other outstanding commitments and
contingent liabilities arising in the normal course of business.
Disposition of these, in the opinion of
management, will not have a material effect upon financial
position.

Note P - Dividend limitation
Under certain banking regulations, regulatory approval is
required before dividends declared by the Corporation's
subsidiary Banks can exceed defined limits. At December 31, 1998,
$14.2 million of retained earnings of subsidiary
Banks are free of such regulatory limitations. There are no such
restrictions regarding the Corporation. As a
practical matter, dividend payments are restricted to lesser
amounts as a result of the maintenance of prudent
capital levels.

Note Q - Regulatory matters
The subsidiaries of the Corporation are subject to various
regulatory capital requirements administered by the
regulatory banking agencies. Failure to meet minimum capital
requirements can initiate certain mandatory and
possible additional discretionary actions by regulators that, if
undertaken, could have a direct material effect
on the Corporation's financial statements. Under capital adequacy
guidelines and the regulatory framework for
prompt corrective action, the  subsidiaries of the Corporation
must meet specific capital guidelines that involve
quantitative measures of assets, liabilities, and certain
off-balance sheet items as calculated under regulatory
accounting practices. The subsidiaries' capital amounts and
classification are 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 Corporation's subsidiaries
to maintain minimum amounts and ratios (set forth in the table
below) of total and tier 1 capital to risk-weighted
assets, and the tier 1 capital to average assets (as defined in
the regulations). Risk-weighted assets are
determined by weighting assets and off-balance sheet exposures
according to their designated relative credit
risks. Tier 1 capital includes certain classes of preferred stock
and equity capital, net of certain adjustments
for intangible assets and investments in non-consolidated
subsidiaries. Total capital consists of tier 1 capital
plus subordinated debt, some types of preferred stock and an
adjustment for allowance for loan losses. Management
believes, as of December 31, 1998, the Corporation's subsidiaries
meet all capital adequacy requirements to which
they are subject.

Note Q - Regulatory matters (continued)
The total and Tier 1 capital amounts and ratios on a consolidated
basis and for Old Second, a
significant subsidiary of the Corporation, are set forth in the
table below. Included are the minimum
ratios as defined by regulatory agencies to maintain minimum
Capital Adequacy and to be Well
Capitalized Under Prompt Corrective Action Provisions and the
actual amounts on a consolidated basis
and for Old Second that satisfy such minimums.

Note R - Fair value of financial instruments
Statements of Financial Accounting Standard Number 107,
"Disclosure About Fair Value Of Financial
Instruments" requires that the Corporation disclose estimates,
methods, and assumptions  used in
determination of the fair values of the Corporation's financial
instruments, as set forth below.


Cash and cash equivalents, securities sold under agreement to
repurchase and other short-term
borrowings 
For these short-term instruments, the carrying amount is a
reasonable estimate of fair value.

Investment securities
For investment securities, fair values are based on quoted market
prices or dealer quotes. If a
quoted market price is not available, fair value is estimated
using quoted market prices for similar
securities.

Loans
Fair values are estimated for portfolios of loans with similar
financial characteristics. Loans are
segregated by type, such as commercial, commercial real estate,
residential mortgage, credit card,
and other consumer. Each loan category is further segmented into
fixed and adjustable rate interest
terms. Cash flows are discounted using current rates at which
similar loans would be made to
borrowers with similar credit ratings and for the same remaining
maturities.

Deposit liabilities
The fair value of demand deposits, savings accounts, and certain
money market deposits is the amount
payable on demand at the reporting date. The fair value of
fixed-maturity certificates of deposit is
estimated by discounting future cash flows at rates currently
offered for deposits of similar
remaining maturities.

Notes payable 
Rates currently available to the Corporation for debt with
similar terms and remaining maturities are
used to estimate fair value of existing debt.

 <PAGE>


Note R - Fair value of financial instruments (continued)
Commitments to extend credit and standby letters of credit

The fair value of commitments is estimated using the fees
currently charged to enter into similar
agreements, taking into account the remaining terms of the
agreements and the present
creditworthiness of the counterparts. For fixed-rate loan
commitments, fair value also considers the
difference between current levels of interest rates and the
committed rates. The fair value of
letters of credit is based on fees currently charged for similar
agreements or on the estimated cost
to terminate them or otherwise settle the obligations with the
counterparties at the reporting date.



The carrying amount and estimated fair value of the Corporation's
financial instruments are as

                     Report of Independent Accountants


Stockholders and Board of Directors
Old Second Bancorp, Inc.

We have audited the accompanying consolidated balance sheets of
Old Second Bancorp, Inc. and Subsidiaries as of December 31, 1998
and 1997, and the related consolidated statements of income,
changes in stockholders' equity, and cash flows
for the three years in the period ended December 31, 1998.  These
financial statements are the responsibility of the Company's management. 
Our responsibility is to express an opinion on these financial statements
based on our audits

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 financial statements referred to above
present fairly, in all material respects, the consolidated
financial position of Old Second Bancorp, Inc.
and Subsidiaries as of December 31, 1998, and the consolidated
results of their operations and their cash flows for each of the
three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.
