* Interest income and yield on tax-exempt securities are not                
  reflected in the tables on a tax-equivalent basis. Net yield on    
  interest-earning assets is net interest divided by total average          
  interest-earning assets.

to change due to volume and change due to rate in proportion to the
the relationship of the absolute dollar amounts of the change in each.

                    Interest Rate Repricing Gaps

The management of interest rate sensitivity is accomplished by monitoring the
maturities and repricing opportunities of interest-earning assets and
interest-bearing liabilities. Amounts are positioned into rate maturity
periods based upon contractual or historical experience of frequency of
repricing the respective assets and liabilities. The following table
summarizes the interest rate repricing gaps for selected maturity periods as
of December 31, 1995:

Total interest-earning assets exceeded interest-bearing liabilities by
$109,660,000 at December 31, 1995. This difference was funded through
noninterest-bearing liabilities and stockholders' equity. The above table
shows that total interest-bearing liabilities maturing or repricing within
one year exceed interest-earning assets maturing or repricing by
$25,773,000. Theoretically, in a period of rising interest rates, it is
preferable to have a positive gap (interest-earning assets in excess of
interest-bearing liabilities) because more interest-earning assets should
mature or reprice within a given time period than interest-bearing
liabilities to increase interest income in excess of the increase in interest
expense. Conversely, theoretically, in a period of declining interest rates,
it is preferable to be in a negative gap position (interest-bearing
liabilities in excess of interest-earning assets) because more interest-
bearing liabilities should mature or reprice to lower interest expense in
excess of the decline in interest income. Because assets and liabilities do
not reprice in exactly the same manner as interest levels change, the above
table should not be viewed as a sole indicator of how the Bancorp will be
affected by changes in interest rates.

interest rates.  Such loans with fixed rates totaled $27,468,000.  Real
estate construction loans due after one year in the amount of $6,316,000 
have floating or adjustable interest rates.  Such loans with fixed rates 
totaled $1,268,000.  Floating or adjustable interest rate loans are those

other rate changes.  Fixed rate loans are those on which the interest rate 
cannot be changed for the term of the loan.

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 days 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,  
Bancorp'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 
loan accounts 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 current adverse economic conditions.  The collateral position of
Bancorp'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.  Amounts for Potential Loan Problems
for 1993, 1992, and 1991 have not been restated for the inclusion of Bank of

Item 2.  Properties


     Except for certain teller machine locations, Old Second Bancorp 
subsidiaries own 13 bank locations. Old Second National Bank leases 
space for the Trust office in Geneva.  Old Second's main banking office 
located at 37 South River Street, Aurora, Illinois has a total 
of approximately 82,000 square feet.  The original, five story, 30,000
square foot building was built in 1925, and a two story, 24,000 square
foot addition was constructed in 1982.  A 28,000 square foot building 
adjacent to the main bank is used for a ten lane drive-in bank facility 
and banking offices.  Parking facilities are provided for approximately 
100 cars.  Old Second leases to others about 13,700 square feet of 
building space and utilizes the remainder for its own operations.


Item 3.  Legal Proceedings

     In the normal course of business, Old Second Bancorp, Inc. and its
subsidiary Banks are party to several legal proceedings, none of which are

Item 9.  Changes in and Disagreements with Accountants on Accounting and
Financial Disclosure 

    On February 3, 1995, the Corporation notified its previous independent
accountants, Coopers & Lybrand, L.L.P. ("Coopers & Lybrand") that Coopers &
Lybrand would not be retained as the Company's independent accountants for
the 1995 fiscal year.  The decision to change independent accountants was
recommended by the Corporation's Audit Committee and approved by the
Board of Directors.  

   Coopers & Lybrand's report on the Corporation's financial statements
during the two most recent fiscal years in which Coopers & Lybrand was 
retained contained no adverse opinion or a disclaimer of opinions, and was 
not qualified or modified as to uncertainty, audit scope, or accounting
principles.  During those two fiscal years, there were no disagreements
between the Corporation and Coopers & Lybrand on any matters of accounting 
principles, financial statement disclosure or auditing scope or procedure.

   None of the "reportable events" described under Item 304(a)(1)(v) of
Regulation S-K promulgated under the Securities Exchange Act of 1934
("Regulation S-K") occurred during those two fiscal years.  In addition,
during those two fiscal years, the Corporation did not consult Ernst &
Young regarding any of the matters or events set forth in Item 304(a)(2)(i)
and (ii) of Regulation S-K.
