                                   (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.

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

Total assets of Hills  Bancorporation  are $691.5  million at March 31, 1999 and
that is an increase  of $64.0  million  from March 31,  1998.  This  increase in
assets  includes  an  increase in net loans  between  years of $40.3  million or
11.67% and  resulted  in net loans  outstanding  of $481.3  million at March 31,
1999.  The  majority of the loans were real estate  loans  secured by 1-4 family
mortgages.  With  both a  strong  local  and  national  economy  continuing  and
favorable  loan rates this  increase in loans was  possible.  Other  significant
changes in assets were a $14.9  million  increase in the  investment  securities
held and a reduction in federal funds of $5.5 million.

The asset  increases  were  funded  primarily  by a $57.7  million  increase  in
deposits and securities  sold under  agreements to  repurchase.  Since March 31,
1998,  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  1999,  Hills  Bancorporation  paid a dividend of $1.30 per share,  a
8.33%  increase  from the $1.20  paid in January  1998.  The total  dividend  of
$1,911,000  is  deducted  from  stockholders'  equity  and is  reflected  in the
resulting   stockholders'   equity  as  of  March  31,   1999  of   $55,780,000.
Stockholders'  equity  at March 31,  1999 and  December  31,  1998  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,  1999
before the reduction for the ESOP shares, as a percent of total assets is 9.46%.
Under risk-based capital rules, total capital is 15.06% of risk adjusted assets,
compared to the current 8% requirement.

Net Income was  $2,079,000  and $1,844,000 for the three months ending March 31,
1999 and 1998,  respectively.  This is an increase  of  $235,000 or 12.74%.  The
increase is due to a $488,000 increase in net interest income and an increase in
other income of $239,000.  The increase in net interest  income is due primarily
to  average  earning  assets for the first  quarter of 1999 being  approximately
$47.4 million higher than the balances in 1998 for the three months ending March
31, 1999.  The increases in other income  includes  $47,000 in loan  origination
fees,  $69,000 in trust fees and $123,000 in deposit  account  charges and other
fees and charges.  Other expenses  increased in 1999 for the period  compared to
1998 by a total of  $347,000.  The largest  increase  was noted in salaries  and
employee benefits which increased $277,000, the result of salary adjustments and
new staff added in the first quarter of 1999.

Basic and diluted  earnings per share  increased for the quarter ended March 31,
1999  compared to 1998.  For the period  ending March 31, 1999 basic and diluted
earnings per share were $1.41 and $1.39 in comparison to $1.26 and $1.24 for the
quarter ending March 31, 1998.

The  Company's  principal  sources of funds  continues to be  prepayment of loan
principal and current amortized loan payments.  In addition,  funds are provided
from current operations.  All of the funds are used to fulfill loan commitments,
make  short-term  investments,  and fund any  deposit  withdrawals  needed.  The
Company has no material  commitments or plans which will  materially  affect its
liquidity or capital resources. The acquisition of property and equipment may be
in cash purchases, or they may be financed if favorable terms are available.

Year 2000

The  Year  2000  poses  an  important  business  issue  regarding  how  existing
application  software  programs and operating  systems can accommodate this date
value.  Many computer programs that can only distinguish the final two digits of
the year  entered  are  expected  to read  entries for the Year 2000 as the Year
1900. Like most financial  service  providers,  the Company may be significantly
affected  by the Year 2000  issues due to the nature of  financial  information.
Software,  hardware and equipment  both within and outside the Company's  direct
control and with whom the Company electronically or operationally interfaces are
likely to be  affected.  If  computer  systems  are not  adequately  changed  to
identify  the  Year  2000,  many  computer  applications  could  fail or  create
erroneous  results.  As a result,  may calculations  that rely on the data field
information,  such  as  interest,  payment  or due  dates  and  other  operating
functions,  may generate results that could be significantly  misstated, and the
Company  could  experience  a temporary  inability to process  transactions  and
engage in normal business activities.



All of the significant  computer  programs of the Company that could be affected
by this issue are provided by major  third-party  vendors.  In 1998, the Company
completed  the  replacement/upgrading  of  most  of  its  computer  systems  and
programs,  as well as most  equipment,  in order to provide  cost-effective  and
efficient delivery of services to customers,  information to management,  and to
provide additional  capacity for processing  information and transactions due to
acquisitions.  The  third-party  vendors  have advised the Company that all such
computer systems and programs either are or shortly will be Year 2000 compliant.
The Company completed off-site testing of its major applications in 1998.

The  total  cost of the Year  2000  project  was  approximately  $1,180,000  for
capitalized  hardware and software and an additional $88,000 in expenses charged
to earnings in 1998.  Management estimates the cost of the remediation effort to
make the Company's  systems Year 2000 ready will be approximately  $40,000 to be
charged to expense in 1999 and $105,000 to be  capitalized in 1999. In addition,
it is  estimated  that 2,000 man hours  will be  incurred  by Company  personnel
related to Year 2000 issues at an approximate cost of $40,000.
Such costs will be charged to expense as they are incurred.

The Company is developing a Year 2000  contingency  plan that  addresses,  among
other issues, critical operations and potential failures thereof, and strategies
for business continuation.  The contingency plan includes back up power sources,
off-site  processing of data and a detailed  listing of  responsibilities  among
various employees of their  contingency plan duties.  The plan is expected to be
finalized during the third quarter of 1999.

The Company  could incur  losses if loan  payments  are delayed due to Year 2000
problems affecting significant borrowers. The Company is communicating with such
parties to assess their progress in evaluating and  implementing  any corrective
measures  required by them to be Year 2000 ready.  To date, the Company has been
advised by such parties that they have plans in place to address and correct the
issues associated with the Year 2000 problem; however, no assurance can be given
as to the adequacy of such plans or to the  timeliness of their  implementation.
As part of the  current  credit  approval  process,  new and  renewed  loans are
evaluated  as to  the  borrower's  Year  2000  readiness.  Management  does  not
anticipate significant loan losses related to this issue.

Although   management  believes  the  Company's  computer  systems  and  service
providers will be Year 2000 ready, there can be no assurance that these systems,
or those systems of other companies on which the Company's systems rely, will be
fully functional in the Year 2000. Such failure could have a significant adverse
impact on the financial  condition and results of operations of the Company.  In
addition,  there could be a material effect to the financial statements if there
are  significant  interruptions  in basic  services,  such as the electric power
grid, telephone services or the banking system. These risks cannot be estimated.
