                                   (unaudited)



Note 1. Interim Financial Statements

Interim consolidated  financial statements have not been examined by independent
public  accountants,  but include  all  adjustments  (consisting  only of normal
recurring  accruals)  which,  in the opinion of management,  are necessary for a
fair presentation of the results for these periods. The results of operation for
the interim  periods are not  necessarily  indicative  of the results for a full
year.

In reviewing these financial  statements,  reference should be made to the Notes
to Financial Statements contained in the Financial Statements for the year ended
December 31, 1999.

There were no changes in accounting  policies which had a significant  effect on
the interim consolidated financial statements for the periods presented.

For purposes of reporting  cash flows,  cash and due from banks includes cash on
hand and amounts due from banks  (including  cash items in process of clearing).
Cash flows from demand deposits,  NOW accounts,  savings  accounts,  and federal
funds  purchased and sold are reported net since their  original  maturities are
less than three months. Cash flows from loans and time deposits are presented as
net increases or decreases.

Note 2. Loans

The following  tables set forth the  composition  of loans and the allowance for
loan losses:

Note 3. Earnings Per Share

Basic net income per share  amounts are  computed by dividing  net income by the
weighted average number of common shares outstanding during the period.  Diluted
earnings per share are  computed by dividing net income by the weighted  average
number of  common  shares  outstanding  during  the  period  plus the  number of
potential  dilutive  common shares  attributable  to the Company's  stock option
plan.




                                 PART I, ITEM 2.
                              HILLS BANCORPORATION
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF THE FINANCIAL CONDITION AND RESULTS OF OPERATIONS



Forward Looking Information

Forward looking  information  relating to the financial results or strategies of
the  Company  may be made  in the  Management's  Discussion  and  Analysis.  The
following paragraphs identify forward looking statements and the risks that need
to be considered when reading those statements.

Forward looking  statements include such words as believe,  expect,  anticipate,
target,  goal,  objective and other words with similar  meaning.  The Company is
under no obligation to update such statements.

The risks  involved in the  operations  and  strategies  of the Company  include
competition  from  other  financial  institutions,  changes in  interest  rates,
changes in economic or market  conditions  and  changes in  regulatory  factors.
These risks, which are not all inclusive, cannot be estimated.

Recent Activities

The  first  quarter  of 2000 saw the  opening  of our  Cedar  Rapids  office  in
February,  representing  the tenth  location for which our customers can conduct
their banking business.  This downtown Cedar Rapids office also represents a new
market area for Hills  Bancorporation.  At the end of this quarter  consolidated
total assets  exceeded $803 million which resulted from continued  growth in all
offices.  In March 2000 the Company  started  construction  of a new  operations
center in Hills which will house employees from our Coralville operations center
and  provide  expansion  of  Trust  operations  and  other  retail  departments.
Completion is expected in February 2001 and total construction  expenditures are
expected to total approximately $3,100,000.

Financial Position

Total assets of Hills  Bancorporation  are $803.4  million at March 31, 2000 and
that is an increase of $111.9  million  from March 31,  1999.  This  increase in
assets  includes  an  increase  in net loans of $98.4  million  or 20.45% and is
reflected in net loans  outstanding  of $579.8  million at March 31,  2000.  The
majority  of the loans were real estate  loans  secured by  mortgages.  Over $56
million  of the net loan  increase  was in 1-4 family  real  estate  loans.  The
increase  in  loans  resulted  from a  strong  local  economy  and  an  improved
competitive  position relative to one of the banks in the Iowa City market,  and
was achieved  despite a trend of higher interest rates. The asset increases were
funded  primarily by a $47.5 million  increase in deposits and  securities  sold
under agreements to repurchase and Federal Home Loan Bank notes borrowings which
increased  by a net of $58.0  million.  Due to the  continued  loan  demand  and
challenges for funding sources  asset-liability  management continues to be very
important.  The  asset-liability  management  encompasses both the management of
interest rate  sensitivity and the maintenance of adequate  liquidity.  Interest
rate  sensitivity  management  attempts  to  provide  the  optimal  level of net
interest income while managing  exposure to risks  associated with interest rate
movements.  Liquidity  management  involves planning to meet anticipated funding
needs.  Management  monitors the rate sensitivity and liquidity  positions on an
on-going basis and, when necessary,  appropriate action is taken to minimize any
adverse  effects of rapid interest rate  movements or any  unexpected  liquidity
concerns.

In January 2000,  Hills  Bancorporation  paid a dividend of $1.45 per share,  an
11.5%  increase  from the $1.30  paid in January  1999.  The total  dividend  of
$2,169,000  is  deducted  from  stockholders'  equity  and is  reflected  in the
resulting   stockholders'   equity  as  of  March  31,   2000  of   $59,912,000.
Stockholders'  equity  at March 31,  2000 and  December  31,  1999  reflects  an
adjustment for unrealized gain (losses) on debt securities, net of income taxes.
The total  stockholders'  equity of Hills  Bancorporation  as of March 31,  2000
before the reduction for the ESOP shares, as a percent of total assets is 8.84%.
Under risk-based capital rules, total capital is 14.41% of risk adjusted assets,
compared to the current 8% requirement.



Results of Operations

Net income was  $2,204,000  and $2,079,000 for the three months ending March 31,
2000 and 1999,  respectively.  This is an increase  of  $125,000  or 6.01%.  The
increase is due to a $781,000 increase in net interest income and an increase in
other income of $134,000.  The increase in net interest  income is due primarily
to  average  earning  assets for the first  quarter of 2000 being  approximately
$99.1 million  higher than the balances in 1999 for the three months ended March
31,  1999.  Also  in  the  first  quarter  Hills  Bancorporation  increased  its
borrowings  from the Federal Home Loan Bank by a net $25 million  from  December
31, 1999 in anticipation of higher interest rates and loan funding  requirements
during the second and third quarter of this year. Due to higher secondary market
interest rates,  loan  origination fees were down for the quarter by $152,000 to
$47,000.  Trust fees and deposit account charges increased over the quarter from
one year ago to $180,000 or 18.4% due primarily to volume  increases in accounts
under management and number of deposit accounts, respectively.

Other  expenses  increased by $648,000 in the first  quarter of 2000 compared to
the  prior  year.  $318,000  of this was in the area of  salaries  and  employee
benefits  which was the result of new staff added and salary  adjustments in the
first  quarter  of 2000  compared  to the  same  quarter  in 1999.  In  addition
occupancy  expenses increased in the first quarter of 2000 due to the opening of
the new branch in Cedar Rapids.

Earnings per share,  both basic and  diluted,  increased  for the quarter  ended
March 31, 2000 compared to 1999. Basic and diluted earnings per share were $1.47
and $1.46 for the quarter  ended March 31, 2000  compared to $1.41 and $1.39 for
the quarter ended March 31, 1999

Market Risk Management

Market risk is the risk of earnings volatility that results from adverse changes
in interest  rates and market  prices.  The  Company's  market risk is comprised
primarily of interest  rate risk arising  from its core  banking  activities  of
lending  and  deposit  taking.  Interest  rate risk is the risk that  changes in
market  interest rates may adversely  affect the Company's net interest  income.
Management  continually  develops and applies  strategies to mitigate this risk.
Management does not believe that the Company's primary market risk exposures and
how those exposures have been managed to-date in 2000 changed significantly when
compared to 1999.

Asset/Liability Management

The Company has a fully integrated  asset/liability  management system to assist
in managing the balance sheet. The process, which is used to project the results
of alternative  investment  decisions,  includes the  development of simulations
that  reflect the effects of various  interest  rate  scenarios  on net interest
income.  Management  analyzes the  simulations to manage interest rate risk, the
net interest margin and levels of net interest income.

The  goal is to  structure  the  balance  sheet  so  that  net  interest  margin
fluctuates  in a narrow range during  periods of changing  interest  rates.  The
Company  currently  believes that net interest  income would fall by less than 4
percent if interest  rates  increased  or  decreased  by 300 basis points over a
one-year time horizon. This is within the Company's policy limits.

To  improve  net  interest  income  and lessen  interest  rate risk,  management
continues its strategy of de-emphasizing  fixed-rate portfolio  residential real
estate  loans with long  repricing  periods.  The Company  continues to focus on
reducing interest rate risk by emphasizing growth in variable-rate  consumer and
commercial loans.  Other actions include the use of fixed-rate Federal Home Loan
Bank  (FHLB)  advances  as  alternatives  to  certificates  of  deposit,  active
management of the available for sale investment  securities portfolio to provide
for cash flows that will facilitate interest rate risk management.

The highly  competitive  banking  environment  in Iowa also greatly  impacts the
Company's net interest margin.  The effect of competition on net interest income
is difficult to predict.
