                                   (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.  Changes in Accounting Policies

SFAS No. 130, "Reporting  Comprehensive  Income" was issued in June 1997 and was
adopted  January 1, 1998 for the initial period ended March 31, 1998.  Statement
#130  establishes  standards  for  reporting  comprehensive  income in financial
statements.  The Company has presented a Statement of Comprehensive Income. SFAS
No.  131,"Disclosures  About Segments of an Enterprise and Related  Information"
expands certain reporting and disclosure  requirements for segments from current
standards.  Statement  #131 will be  effective  for the year ended  December 31,
1998,  but the Company  operates in one business  segment and the Statement will
have no effect on the financial statements.

Note 4.  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 weighed  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


The consolidated  balance sheet of Hills Bancorporation as of September 30, 1998
reflects  total assets of $654.2  million  which is an increase of $51.1 million
from  December  31,  1997.  Net loans  increased  from $422.8  million to $447.0
million,  which represents an increase of $24.2. Compared to one year ago, total
assets have  increased  from $592.1 million to $654.2 million for an increase of
$62.1  million.  Also during this year,  net loans  increased  $32.1  million to
$438.1 million as of September 30, 1998. Loan demand continues to be very strong
due to a  continued  strong  local  economy and a favorable  low  interest  rate
environment.  Single  family  loans and other real  estate  loans  continued  to
account for the majority of the loan growth.

Other significant  balance sheet changes from December 31, 1997 to September 30,
1998 are as follows:

o    Available for sale investment securities increasing $11.2 million to $120.6
     million.  o Federal funds sold were $17.3 million  higher at September 30th
     than December 31, 1997.

o    Deposits  including  securities sold under agreements to repurchase totaled
     $510.6 million at September 30, 1998 compared to $488.8 million at December
     31, 1997.

o    Federal  Home Loan Bank's  borrowings  increased a net $25 million as Hills
     Bank and Trust Company took  advantage of lower  interest rates on four and
     five year advances available.

o    Also due to lower investment rates accumulated other  comprehensive  income
     which was all  unrealized  gains on investment  securities  increased  from
     $485,000 at December 31, 1997 to $1,244,000 at September 30, 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  1998,  Hills  Bancorporation  paid a dividend of $1.20 per share,  a
14.29%  increase  from the $1.05 paid in January  1997.  The total  dividend  of
$1,763,000  is  deducted  from  stockholders'  equity  and is  reflected  in the
resulting  stockholders'  equity  as  of  September  30,  1998  of  $54,850,000.
Stockholders'  equity at September  30, 1998 and  December 31, 1997  reflects an
adjustment for unrealized gain (losses) on debt securities, net of income taxes.
The total stockholders'  equity of Hills Bancorporation as of September 30, 1998
before the reduction for the ESOP shares, as a percent of total assets is 9.73%.
Under risk-based capital rules, total capital is 15.06% of risk adjusted assets,
compared to the current 8% requirement.

Net income for the quarter ending September 30, 1998 increased  $66,000 from the
previous year's quarter.  Net interest income increased  $424,000 and $1,318,000
for the quarter and the nine months  ending  September  30, 1998 compared to the
same time periods in 1997. The increase in net interest  income  continues to be
due to  significant  increases in the volume of earning  assets during the first
nine months of 1998 compared to 1997. The increase in average earning assets for
the nine months ending September 30, 1998 compared to the same months in 1997 is
approximately $65.8 million and is due primarily to average net loans increasing
$42.8 million and the  investment  in federal funds being $19.3 million  higher.
The large  federal  fund  balances  were the result of funds  borrowed  from the
Federal Home Loan Banks  earlier in 1998 to be used for funding of expected loan
growth.  A significant  other income item in the second  quarter of 1997 was the
recognition  of $1,054,000 on the sale of a marketable  equity  security held by
Hills  Bancorporation.   The  equity  security  was  transferred  to  the  Hills
Bancorporation   Foundation,   a  private   charitable   foundation,   organized
exclusively for charitable and  educational  purposes to benefit the communities
which  the  banks'  serve.  As  a  result  of  the  stock  contribution,   Hills
Bancorporation received an income tax savings of approximately $340,000 which is
reflected as tax savings in the federal and state  income taxes  expense for the
second quarter of 1997.



Other income changes occurred in loan  origination fees which increased  $49,000
for the three months ended September 30, 1998 from one year ago and $263,000 for
the nine months ending  September 30 1998,  compared to the same period in 1997.
Trust fees showed growth over 1997 with an $81,000  increase for the quarter and
$319,000  for the  nine  months.  Other  expenses,  excluding  the  contribution
discussed above increased  $514,000 and $1,705,000 for the third quarter and the
nine months ended  September 30, 1998  compared to the same period in 1997.  The
major  portion of this  increase was $921,000  increase in salaries and employee
benefits as full-time equivalent employees increased by thirty and normal yearly
increases  for existing  employees.  Also the full service  Mount Vernon  office
opened in February, 1998 and has ten employees. All other operating expenses are
up  $784,000  as a result of increase in  marketing,  other  professional  fees,
expenses  relating  to the new bank in Mount  Vernon and other  data  processing
charges.

Basic and diluted  earnings per share for the three months ending  September 30,
1998  were  $1.24  and $1.22 in  comparison  to $1.19 and $1.18 for the  quarter
ending  September  30,  1997.  The  earnings per share for the nine months ended
September  30,  1998 and  September  30,  1997  were  $3.68  and $3.61 for basic
earnings  per share and $3.62 and $3.58 for diluted  earnings per share for both
periods presented.

The  Bank'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 Company and its three wholly-owned  subsidiary  commercial banks, Hills Bank
and Trust Company, Hills, Iowa; Hills Bank, Lisbon, Iowa; and Hills Bank Kalona,
Kalona, Iowa are taking the appropriate  measures to be ready for the Millennium
change.  The Banks' "Y2K"  readiness plan is being  implemented  and a Year 2000
committee  to  oversees  its  progress.  To date the Company  has  completed  an
inventory and  assessment of all  computers,  equipment and software  containing
date  sensitive  functions.  Contact  has been  made with the  vendors  of these
products to determine Year 2000 compatibility.

A  renovation  schedule  is being  followed  to replace  or  upgrade  identified
products which are not Year 2000  compliant.  In 1998, the Company  replaced its
primary computer system with a newer Year 2000 compliant system and has received
a warranty  from the software  company that the software  will operate after the
Year 2000  without  error  relating to date data.  In  addition,  the  Company's
critical  information systems are in the process of being tested to make certain
that by the end of 1998 the systems will be ready - one year ahead of the actual
changeover.

Contingency Plans

The Company is also working on  contingency  plans that will  provide  alternate
methods of doing business,  if needed. The Year 2000 issues for banks depend not
only on compliance of the banks' software and equipment,  but also on compliance
by all of the other institutions with which the banks do business.  Four federal
regulatory  agencies,  which share the responsibility for supervising efforts by
banks and savings  associations  to make sure that they are taking the necessary
steps now to get ready for the Year 2000 date  change.  The Banks  already  keep
backup  records  for account  transactions  and will  continue  to do so.  These
records could be used to correct and identify  errors that might affect deposit,
loan or other account information due to a Year 2000 problem.

Risks

In the early weeks of 2000, the Company may experience  some random supply chain
disruption  that may affect its ability to produce and  distribute key products.
These  disruptions  will  be  material  if  the  U.S.  experiences   significant
interruptions  in basic  services,  such as the electric  power grid,  telephone
service or the banking system.

Costs

The Banks replaced its primary computer system during the first quarter of 1998.
Since most of these types of  upgrades or  renovations  will be  capitalized  as
property and  equipment and  depreciated  it is expected that the costs will not
have a significant impact on the earnings or future liquidity of the Company.
