        Basis of Presentation  The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X.  These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown.  Certain prior year amounts may be reclassified to conform to the current year presentation.  Operating results for the six month period ended June 30, 2005 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2005.  For further information, refer to the consolidated financial statements and footnotes thereto included in the Form 10-K Annual Report of Hills Bancorporation and subsidiary (the Company) for the year ended December 31, 2004 filed with the Securities Exchange Commission on March 10, 2005.  Note 2.
        Earnings Per Share  Basic earnings per share amounts are computed by dividing net income (the numerator) by the weighted average number of common shares outstanding (the denominator) during the period.  Diluted per share amounts assume the conversion, exercise or issuance of all potential common stock equivalents unless the effect is to reduce the loss or increase the income per common share from continuing operations.  The computation of basic and diluted earnings per share for the periods presented is as follows:  Three months ended

        Recent Accounting Pronouncements  In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 123 (Revised 2004), Share-Based Payment. SFAS No 123R is a revision of SFAS No. 123, Accounting for Stock-Based Compensation and supersedes Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees and its related implementation guidance. SFAS No. 123R focuses primarily on accounting for transactions in which an entity obtains employee services through share-based payment transactions. SFAS No 123R requires a public entity to measure the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant. The cost will be recognized over the period during which an employee is required to provide services in exchange for the award.
The date at which SFAS No. 123R is expected to apply to the Company was recently extended from the beginning of the first interim or annual reporting period which begins after June 15, 2005 to January 1, 2006.  While the Company cannot precisely determine the impact on net earnings as a result of the adoption of SFAS No 123R, estimated compensation expense can be found in the table below. The ultimate amount of increased compensation expense will be dependent on whether the Company adopts SFAS 123R using the modified prospective or retrospective method, the number of option shares granted during the year, their timing and vesting period, and the method used to calculate the fair value of the awards, among other factors.

        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations  The following is managements discussion and analysis of the financial condition of Hills Bancorporation (Hills Bancorporation or the Company) and its banking subsidiary Hills Bank and Trust Company (the Bank) for the dates and periods indicated.  The discussion and analysis should be read in conjunction with the consolidated financial statements and the accompanying footnotes.  Special Note Regarding Forward Looking Statements  This report contains, and future oral and written statements of the Company and its management may contain, forward-looking statements within the meaning of such term in the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations, plans, objectives, future performance and business of the Company. Actual results may differ materially from those included in the forward-looking statements.  Forward-looking statements, which may be based upon beliefs, expectations and assumptions of the Companys management and on information currently available to management, are generally identifiable by the use of words such as believe, expect, anticipate, plan, intend, estimate, may, will, would, could, should or other
similar expressions. Additionally, all statements in this document, including forward-looking statements, speak only as of the date they are made, and the Company undertakes no obligation to update any statement in light of new information or future events.  The Companys ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors which could have a material adverse effect on the operations and future prospects of the Company include, but are not limited to, the following:  
        The strength of the United States economy in general and the strength of the local economies in which the Company conducts its operations which may be less favorable than expected and may result in, among other things, a deterioration in the credit quality and value of the Companys assets.  
        The effects of, and changes in, laws, regulations and policies affecting banking, securities, insurance and monetary and financial matters as well as any laws otherwise affecting the Company.  
        The effects of changes in interest rates (including the effects of changes in the rate of prepayments of the Companys assets) and the policies of the Board of Governors of the Federal Reserve System.  
        The ability of the Company to compete with other financial institutions as effectively as the Company currently intends due to increases in competitive pressures in the financial services sector.  
        The ability of the Company to obtain new customers and to retain existing customers.  
        The timely development and acceptance of products and services, including products and services offered through alternative delivery channels such as the Internet.  
        Technological changes implemented by the Company and by other parties, including third party vendors, which may be more difficult or more expensive than anticipated or which may have unforeseen consequences to the Company and its customers.  
        The ability of the Company to develop and maintain secure and reliable electronic systems.   Page 11 of 31      HILLS BANCORPORATION  Item 2.
        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)   
        The ability of the Company to retain key executives and employees and the difficulty that the Company may experience in replacing key executives and employees in an effective manner.  
        Consumer spending and saving habits which may change in a manner that affects the Companys business adversely.  
        The economic impact of terrorist attacks and military actions.  
        Business combinations and the integration of acquired businesses and assets which may be more difficult or expensive than expected.  
        The costs, effects and outcomes of existing or future litigation.  
        Changes in accounting policies and practices, as may be adopted by state and federal regulatory agencies and the Financial Accounting Standards Board.  
        The ability of the Company to manage the risks associated with the foregoing as well as anticipated.  These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. Additional information concerning the Company and its business, including other factors that could materially affect the Companys financial results, is included in the Companys filings with the Securities and Exchange Commission.  Critical Accounting Policy  The Companys financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The financial information contained within these statements is, to a significant extent, financial information that is based on approximate measures of the financial effects of transactions and events that have already occurred. Based on its consideration of accounting policies that involve the most complex and subjective decisions and assessments, management has identified its most critical accounting policies to be those which are related to the allowance for loan losses. The Companys allowance for loan loss methodology incorporates a variety of risk considerations, both quantitative and qualitative in establishing an allowance for loan loss that management believes is appropriate at each reporting date. Quantitative factors include the Companys
historical loss experience, delinquency and charge-off trends, collateral values, changes in non-performing loans, and other factors. Quantitative factors also incorporate known information about individual loans, including borrowers sensitivity to interest rate movements. Qualitative factors include the general economic environment in the Companys markets, including economic conditions throughout the Midwest and in particular, the state of certain industries. Size and complexity of individual loans in relation to loan structure, existing loan policies and pace of portfolio growth are other qualitative factors that are considered in the methodology. As the Company adds new products and increases the complexity of its loan portfolio, it will enhance its methodology accordingly. This discussion and analysis should be read in conjunction with the Companys financial statements and the accompanying notes presented elsewhere herein, as well as the Managements Discussion and Analysis of
Financial Condition and Results of Operation that is included. Although management believes the levels of the allowance as of June 30, 2005 and December 31, 2004 were adequate to absorb probable losses inherent in the loan portfolio, a decline in local economic conditions, or other factors, could result in increasing losses that cannot be reasonably predicted at this time.   Page 12 of 31      HILLS BANCORPORATION  Item 2.
        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  Overview  The Company is a holding company engaged in the business of commercial banking.  The Companys subsidiary is Hills Bank and Trust Company, Hills, Iowa (the Bank), which is wholly-owned.  The Bank was formed in Hills, Iowa in 1904.  The Bank is a full-service commercial bank extending its services to individuals, businesses, governmental units and institutional customers primarily in the communities of Hills, Iowa City, Coralville, North Liberty, Mount Vernon, Kalona, Cedar Rapids and Marion, Iowa.  On June 28, 2005, the Bank opened a limited purpose office at the Oaknoll Retirement Residence in Iowa City, Iowa for the exclusive use of Oaknoll residents and staff (the Oaknoll Office).  The Oaknoll Office is staffed by existing Bank personnel and is open on the second and fourth Tuesday of each month. The Oaknoll Office opens deposit accounts, provides deposit services,
trust and investment services and check cashing.  The Oaknoll Office does not perform loan origination activities.  At June 30, 2005 the Bank has twelve full service locations.  Net income for the six-month period ended June 30, 2005 was $7.70 million compared to $7.16 million for the same six months of 2004. The increase in 2005 of $543,000 is a 7.59% increase over the 2004 amount.  The factors that resulted in this increase in net income compared to the comparable period in 2004 are discussed below in the Net Income Overview section.  The Banks net interest income is the largest component of revenue and it is primarily a function of the average earnings assets and the net interest margin percentage.  For the six-month period ended June 30, 2005, the average earning assets grew by $118.46 million from $1.129 billion to $1.247 billion, which was the major factor in a $1.76 million increase in net interest income.  The Bank achieved a net interest margin of 3.57% compared to 3.63% in 2004.  Highlights noted on the balance sheet as of June 30, 2005 for the Company included the following: 
        Net loans are $1.059 billion. 
        Loan growth of $61.02 million and deposit growth of $44.4 million since December 31, 2004. 
        Dividends of $.75 per share were paid in January of 2005 to 1,485 shareholders.  The 2005 dividend was a 7.14% increase over the prior years dividend of $.70.  A detailed discussion of the financial condition and results of operations follows this overview.  Financial Condition  The asset growth of $76.8 million included a net loan increase of $61.02 million and an increase in federal funds sold of $15.00 million.  Since December 31, 2004, the federal funds target rate has been raised by the Federal Reserve Open Market Committee from 2.25% to 3.25% with four increases of .25% each or a total of 1.00%.  The upward movement of the federal funds target rate started on June 30, 2004 when the rate was 1.00% and created opportunities for consumers to place funds with institutions offering higher interest rates.  Interest rates on loans are generally affected by these increases since interest rates determined by the U.S. Treasury market normally increase when the Federal Reserve Board raises the federal funds target rate.  The Bank prices its real estate loans based on the U.S. Treasury indexes.  Loans secured by real estate accounted for $50.45 million or 82.68% of the
increase in loans.  Increases in interest rates may at some point affect the loan demand and the economy, but at the current interest rate levels, demand for loans remains good.  The overall economy in the Companys principal place of business, Johnson and Linn Counties, remains good with unemployment levels that remain low.   Page 13 of 31      HILLS BANCORPORATION  Item 2.

     $998,231  The Bank has an established formal loan origination policy.  In general, the loan origination policy attempts to reduce the risk of credit loss to the Bank by requiring that, among other things, maintenance of minimum loan to value ratios, evidence of appropriate levels of insurance carried by borrowers and documentation of appropriate types and amounts of collateral and sources of expected payment.

       Federal funds sold increased from zero at December 31, 2004 to $15.0 million at June 30, 2005.  As discussed below, deposit growth of $44.4 million, short-term borrowing increases and advances from the Federal Home Loan Bank (FHLB) exceeded the funds required for loan growth and the excess is invested on a temporary basis in federal funds sold.  It is expected that some or all of such excess funds will be used to fund loan growth in the third quarter of 2005.  Investment securities decreased $5.4 million, primarily as a result of the maturity in June of 2005 of a short-term tax exempt bond for $3.9 million that was not replaced.  As a result of increasing interest rates, the market value of securities available for sale was only $60,000 more than the amortized cost of such securities at June 30, 2005, which was a steep decline from the $915,000 by which the market value of securities available for sale exceeded the amortized cost of such securities at December 31, 2004.  The carrying values of investment securities for June 30, 2005 and December 31, 2004 are summarized in the following table (dollars in thousands):  June 30, 2005

        %  Deposit growth was $44.4 million in the first six months of 2005 and included $24.3 million in additional retail deposits and $20.1 million in additional commercial and municipal deposit increases.  Short-term borrowings at December 31, 2004 included $18.7 million in repurchase agreements that grew to $25.6 million as of June 30, 2005.  The borrowings from the Federal Home Loan Bank (FHLB) were increased in May, 2005 by $40 million as the Bank decided to borrow longer-term funds.  The borrowings have an interest rate of 3.70% and are fixed for five years.  The excess of funds from deposits, repurchase agreements and the FHLB advances were used to reduce the federal funds borrowed at December 31, 2004 from $19.2 million to zero which accounted for the $15.0 million balance in federal funds sold at June 30, 2005.  In the opinion of the Companys management, the Company continues to have
sufficient liquidity resources available to fund expected additional loan growth.   Page 15 of 31      HILLS BANCORPORATION  Item 2.
        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  In March of 2005, the Bank relocated its downtown Iowa City office to the Old Capitol Town Center.  The relocation doubled the size of the Banks downtown presence to 5,800 square feet.  It is expected that the expanded space will assist in the growth of both retail and commercial deposits and will permit the Bank to offer real estate and commercial loan products at the downtown location.  Dividends and Equity  In January 2005, Hills Bancorporation paid a dividend of $3,413,000 or $.75 per share, a 7.14% increase from the $.70 per share paid in January 2004.  After payment of the dividend and the adjustment for accumulated other comprehensive income, stockholders equity as of June 30, 2005 totaled $106.6 million.  Under risk-based capital rules, the total amount of risk based capital as of June 30, 2005, was 13.73% of risk-adjusted assets, and is substantially in excess of required minimums.  Discussion of operations for the six months ended June 30, 2005 and 2004.  Net Income Overview  Net income increased $543,000 or 7.59% for the six months ended June 30, 2005 compared to the first six months of 2004.  Total net income was $7,700,000 in 2005 and $7,157,000 in the comparable period in 2004.  The changes in net income in 2005 from the first six months of 2004 are as follows and are discussed in detail in the following review of operations:  
        Net interest income increased by $1,762,000. 
        The provision for loan losses increased by $244,000. 
        Other income decreased by $284,000. 
        Other expenses increased by $533,000. 
        Income taxes increased by $158,000.  Earnings per share, both basic and diluted increased for the six months ending June 30, 2005 compared to the six months ending June 30, 2004.  For the six-month period ended June 30, 2005, basic and diluted earnings per share were $1.69 and for June 30, 2004, basic and diluted earnings were $1.57.  Quarterly fluctuations in the Companys net income continue to be driven primarily by three important factors. The first important factor is net interest margin. Net interest income of $21.6 million for the first six months of 2005 was derived from the Companys $1.247 billion of average earning assets and its net interest margin of 3.57%.  Average earning assets in the six months ending June 30, 2004 were $1.129 billion and the net interest margin was 3.63%.  The importance of net interest margin is illustrated by the fact that a decrease in the net interest margin of 10 basis points to 3.47% would have resulted approximately in a $623,000 decrease in income before income taxes in the six month period ending June 30, 2005.  The second significant factor affecting the Companys net income is the provision for loan losses. The majority of the Companys interest-earning assets are in loans outstanding, which amounted to more than $1.059 billion at June 30, 2005. An increase in problem loans results in a higher allocation to the provision for loan losses, which in turn reduces the Companys net income.  The provision for loan losses was $759,000 in 2005 compared to $515,000 in 2004.  The amount of mortgage loans sold on the secondary market is the third factor that can cause fluctuations in net income.  In the six months ended June 30, 2005 and 2004, the net gain on sale of loans was $544,000 and $967,000, respectively.  The sale of loans is influenced by the real estate market and interest rates.  As a result in 2003, when rates were at their lowest level in recent years, the volume of loans sold was high.  The net gain on sale of loans for the six months ended June 30, 2003 was $2,452,000.  Due primarily to higher rates in 2004 and 2005, mortgage activity volume has been reduced from the levels in 2003.   Page 16 of 31      HILLS BANCORPORATION  Item 2.
        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  Discussion of operations for the six months ended June 30, 2005 and 2004 (continued).  Net Interest Income  Net interest income is the excess of the interest and fees received on interest-earning bearing assets over the interest expense of the interest-bearing liabilities.  The factors that have the greatest impact on net interest income are the volume of average earning assets and the net interest margin.  The net interest margin for the first six months of 2005 was 3.57% compared to 3.63% in 2004 for the same period.  The measure is shown on a tax-equivalent basis using a tax rate of 35% to make the interest earned on taxable and non-taxable assets more comparable.  Included in the volume changes column in the table that follows is the time variance between 2005 and 2004 since the six months ended June 30, 2004 had one additional day.  The changes in average balances and average rates and the effect on the net interest income on a tax equivalent basis for the six months ended in 2005 compared to the
comparable period in 2004 are shown in the following table:  Change in

        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  Discussion of operations for the six months ended June 30, 2005 and 2004 (continued).  Provision for Loan Losses  The provision for loan losses was $759,000 in 2005 compared to $515,000 in 2004.  The provision adjustment is computed on a quarterly basis and is a result of managements determination of the quality of the loan portfolio.  The provision reflects a number of factors, including the size of the loan portfolio, loan concentrations, the level of impaired loans (which are non-accrual) and loans past due ninety days or more. The amount of problem or watch loans considered in the reserve computation increased approximately $543,000 or 4.17% from the end of 2004 to June 30, 2005.  The allowance for loan losses balance is also affected by the charge-offs, net of recoveries, for the periods presented.  For the six months ended June 30, 2005 and 2004, recoveries were $584,000 and $559,000, respectively; and charge-offs were $763,000 in 2005 and $599,000 in 2004.  The allowance for loan losses totaled $14,370,000 at June 30, 2005 compared to $13,790,000 at December 31, 2004.  The allowance represented 1.34% and 1.36% of outstanding loans at June 30, 2005 and December 31, 2004, respectively.  The allowance was based on managements consideration of a number of factors, including loan concentrations, loans with higher credit risks (primarily agriculture loans and spec real estate construction) and overall increases in net loans outstanding.  The methodology used in 2005 is consistent with the prior year.  Net Gain on Sale of Loans  Net gain on sale of loans for the six months ended June 30, 2005 was $544,000 compared to $967,000 for the comparable period ended June 30, 2004.  The number of loans sold in 2005 was approximately 58% of the volume in 2004.  The decrease in the volume of loans sold was expected because many consumers had taken advantage of lower interest rates in 2003 and 2004 to refinance loans.  Other Income  Other income, other than the net gain on sale of loans discussed above, increased by $139,000.  The significant items accounting for the net change were an $118,000 increase in trust fees, $171,000 in additional service charges and fees, an increase in rental revenue on tax credit real estate of $88,000 and investment securities losses of $234,000.  The losses were taken on $10.5 million of U.S. Agencies securities and after replacement purchases the average yield increased from 2.71% to 3.77%.  No investment losses were taken in 2004.  The trust fees increase is due primarily to a 6.7% increase in assets under management in the last twelve months with ending assets at June 30, 2005 of $708.6 million.  The increase in service charges is due to volume increases of debit card interchange fees and credit card fees on merchant accounts.  The rental revenue increase is due to the additional property
added in January 2004 being fully rented as of June 30, 2005.   Page 18 of 31      HILLS BANCORPORATION  Item 2.
        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  Discussion of operations for the six months ended June 30, 2005 and 2004 (continued).  Other Expenses  Other expenses increased $533,000 in 2005 to $15,767,000 from the same period in 2004.  This increase of 3.50% included $75,000 in salaries and benefits.  Direct salary expense was up $40,000 due to the addition of seven additional employees in 2005 compared to 2004.  Total full-time equivalents at June 30, 2005 were 373.  Medical expense for employees health insurance increased $58,000 due primarily to the increased number of employees covered in the plan.  Occupancy expense increased $53,000 with rent expense higher by $28,000 due to the new office location in the Old Capitol Town Center which opened in 2005.  Also, property taxes are up $27,000 to $252,000 and are a result of annual increases in the tax rates and the new lease at the Old Capitol Town Center in 2005.  In 2005 furniture and equipment expense included depreciation expense of $964,000 and $470,000 in equipment and software
maintenance contracts.  These expenses one year ago were $960,000 for depreciation and $381,000 for the maintenance contracts.  The increase in 2005 is due to more equipment and software purchases in 2004 and the related five year maintenance contracts.  Outside services increased $154,000 from 2004 to $2.3 million in 2005. Outside services include professional fees, courier services and ATM fees and processing charges for the merchant credit card program, retail credit cards and other data processing services.  The credit card, merchants card and debit card processing charges increased $117,000 due to the increase in the volume of activity.  The fees totaled $805,000 in 2005.  The increase in the rental expenses compared to the same six months of 2004 was $91,000 to $442,000.  The change is due to the new property added in January, 2004 and the property being fully rented in 2005.  Income Taxes  Federal and state income tax expenses were $3,424,000 and $3,266,000 for the six months ended June 30, 2005 and 2004, respectively.  Income taxes as a percentage of income before taxes were 30.78% in 2005 and 31.33% in 2004.  The dollar amount increase of $158,000 is primarily due to an increase of $701,000 in income before income taxes for the six months ended June 30, 2005.  Additional nontaxable income of $82,000 in 2005 reduces the expected increase in income taxes by approximately $32,000 and is further reduced by the amount of tax credits in 2005 which were $338,000, compared to $265,000 in 2004.   Page 19 of 31      HILLS BANCORPORATION  Item 2.
        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  Discussion of operations for the three months ended June 30, 2005 and 2004.   Net Income  Net income decreased from $3,795,000 in the three months ended June 30, 2004 to $3,557,000 in the three months ended June 30, 2005.  Net interest income increased by $685,000 and was partially offset by a $587,000 increase in the loan loss provision.  Another factor that resulted in lower net income was the decrease in gain on sale of secondary market loans from $616,000 in the three months ended June 30, 2004 to $306,000 in the three months ended June 30, 2005.  Net of income taxes, this would account for approximately a $191,000 decrease in net income.  Securities losses were realized in the second quarter of 2005 totaling $234,000.  No securities losses were recognized for the quarter ended June 30, 2004.  All other income items increased for the quarter by $254,000 and other expenses increased $294,000.  Net Interest Income  Net interest income increased for the three month period ended June 30, 2005 by $685,000 from the similar period in 2004.  The net interest margin in 2005 was 3.50% compared to 3.65% in 2004.  The decrease is primarily due to an increase in rates on core deposit accounts, including insured money market accounts and short-term certificates of deposits.  These rates were increased due to the upward movement of the federal fund rates.  The increase in the volume of interest earning assets accounted for a significant portion of the net interest income improvement.  Net interest income changes on a tax-equivalent basis for the three months ended June 30, 2005 and 2004 are as follows:  Change in

        %  Provision for Loan Losses  The provision for loan losses was $748,000 for the quarter ended June 30, 2005 compared to $161,000 in 2004.  As discussed in connection with the results of operations for the six months, the allowance for loan losses was increased due to managements analysis of the outstanding loans at June 30, 2005, which resulted in a higher level of problem loans.  In 2004 the amount of problem or watch loans used in the reserve computation as of June 30, 2004 was only $71,000 higher than at March 31, 2004.  In 2005 the amount of problem or watch loans used in the computation was $588,000 higher at June 30, 2005 than at March 31, 2005.  The allowance for loan losses balance is also affected by the charge-offs, net of recoveries, for the periods presented.  For the three months ended June 30, 2005 and 2004, recoveries were $332,000 and $290,000, respectively; and charge-offs were $460,000 in 2005 and $371,000 in 2004.   The allowance for loan losses totaled $14,370,000 at June 30, 2005 compared to $13,060,000 at June 30, 2004.  The allowance represented 1.34% and 1.38% of outstanding loans at June 30, 2005 and June 30, 2004, respectively.  Other Income  As explained in the preceding discussion of the six month results, net gain on sale of loans was substantially less in 2005 as compared to 2004.  Interest rates were more favorable in 2004 than in 2005.   The Trust Department fees for 2005 were $95,000 higher than 2004 due to the growth of assets under management.  Other income items for debit card fees and ATM service fees were up $99,000 for the quarter ended June 30, 2005, as compared to the same quarter of 2004.  Other Expenses  Total expenses for the 2005 quarter compared to the 2004 quarter increased $294,000 to $8,050,000.  Maintenance on equipment and computer software included in furniture and equipment expense increased $53,000 from 2004 for the quarter ended June 30, 2005 to a total of $235,000.  The increase is due to purchases made the last half of 2004 and the resulting five year maintenance contracts.  Advertising and business development expenses increased $75,000 in comparing the quarters.  The increase is due to direct mail and product promotion items for the retail area of the Bank.  As a result of an increase in the volume of activity, credit card and debit card processing charges increased $62,000 and these expenses are included in outside services expense.

        Managements Discussion and Analysis of Financial ConditionAnd Results of Operations (continued)  Discussion of operations for the three months ended June 30, 2005 and 2004 (continued).  Income Taxes  Income tax expense as a percentage of income before taxes decreased from 31.76% in 2004 to 29.91% in 2005.  Income tax expense is $248,000 less in 2005 compared to 2004 with $211,000 accounted for by less taxable income.  The balance of the decrease is due to an additional $37,000 in tax credits recorded as a result of the new tax credit real estate investment in 2004.  Liquidity  The Company actively monitors and manages its liquidity position with the objective of maintaining sufficient cash flows to fund operations, meet client commitments, take advantage of market opportunities and provide a margin against unforeseeable liquidity needs.  Federal funds sold and investment securities available for sale are readily marketable assets.  Maturities of all investment securities are managed to meet the Companys normal liquidity needs, to respond to market changes or to adjust the Companys interest rate risk position.  Federal funds sold and investment securities available for sale comprised 15.95% of the Companys total assets at June 30, 2005, compared to 15.82% at December 31, 2004.  The Company has historically maintained a stable deposit base and a relatively low level of large deposits, which has mitigated the volatility in the Companys liquidity position.  As of June 30, 2005, the Company had borrowed $207.5 million from the Federal Home Loan Bank (FHLB) of Des Moines.  This includes a new advance in May 2005 for $40 million.  These advances were used as a means of providing both long and short-term, fixed-rate funding for certain assets and for managing interest rate risk.  The Company had additional borrowing capacity available from the FHLB of approximately $177 million at June 30, 2005.  As additional sources of liquidity, the Company has the ability to borrow up to $10 million from the Federal Reserve Bank of Chicago, and has lines of credit with two banks totaling $111 million. Those two lines of credit require the pledging of investment securities when drawn upon.  The combination of high levels of potentially liquid assets, low dependence on volatile liabilities and additional borrowing capacity provided sources of liquidity for the Company which management considered sufficient at June 30, 2005.   Page 22 of 31       HILLS BANCORPORATION  Item 3.  Quantitative and Qualitative Disclosures About Market Risk  Market Risk Management  The Companys primary market risk exposure is to changes in interest rates.  The Companys asset/liability management, or its management of interest rate risk, is focused primarily on evaluating and managing net interest income given various risk criteria.  Factors beyond the Companys control, such as market interest rates and competition, may also have an impact on the Companys interest income and interest expense.  In the absence of other factors, the Companys overall yield on interest-earning assets will increase, as will its cost of funds on its interest-bearing liabilities when market interest rates increase over an extended period of time.  Conversely, the Companys yields and cost of funds will decrease when market rates decline.  The Company is able to manage these swings to some extent by attempting to control the maturity or rate adjustments of its interest-earning assets and
interest-bearing liabilities over given periods of time.  Asset/Liability Management  The Bank maintains an asset/liability committee, which meets at least quarterly to review the Banks interest rate sensitivity position and to review various strategies as to interest rate risk management.  In addition, the Bank uses a simulation model to review various assumptions relating to interest rate movement.  The model attempts to limit rate risk even if it appears the Banks asset and liability maturities are perfectly matched and a favorable interest margin is present.  In order to minimize the potential effects of adverse material and prolonged increases or decreases in market interest rates on the Companys operations, management has implemented an asset/liability program designed to mitigate the Companys interest rate sensitivity.  The program emphasizes the origination of adjustable rate loans, which are held in the portfolio, the investment of excess cash in short or intermediate term interest-earning assets, and the solicitation of passbook or transaction deposit accounts, which are less sensitive to changes in interest rates and can be re-priced rapidly.  Net interest income should decline as interest rates increase, while net interest income should increase as interest rates decline.  Generally, during periods of increasing interest rates, the Companys interest rate sensitive liabilities would re-price faster than its interest rate sensitive assets causing a decline in the Companys interest rate spread and margin.  This would tend to reduce net interest income because the resulting increase in the Companys cost of funds would not be immediately offset by an increase in its yield on earning assets. In times of decreasing interest rates, fixed rate assets could increase in value and the lag in re-pricing of interest rate sensitive assets could be expected to have a positive effect on the Companys net interest income.   Page 23 of 31       HILLS BANCORPORATION  Item 4.  Controls and Procedures  The Company carried out an evaluation, under the supervision and with the participation of the Companys management, including the Companys Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Companys disclosure controls and procedures as defined in Exchange Act of 1934 Rule 13a-15(f).  Based upon that evaluation, the Companys Chief Executive Officer and Chief Financial Officer concluded that the Companys disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports it files with the Securities and Exchange Commission.  There have been no changes in the Companys internal controls over financial reporting during the first six months of 2005 that have materially affected, or are
reasonably likely to materially affect, the Companys internal controls over financial reporting.   Page 24 of 31      HILLS BANCORPORATION PART II - OTHER INFORMATION   Item 1.

        Other Information  (a)
        On February 22, 2001, the Bank made a commercial loan to a borrower who operated a lawn care business (the Lawn Care Borrower) in the amount of $58,265 and on June 12, 2003 the Bank made an additional commercial loan to the Lawn Care Borrower, advanced primarily to rewrite a prior loan dated May 6, 2002,  in the amount of $18,252.  Director Pacha co-signed the notes for these amounts (the Lawn Care Notes) when the loans were made to the Lawn Care Borrower.  On March 7, 2003, Director Pacha made a final payment on the first loan in the amount of $54,588, resulting in the first loan being paid in full.  On December 10, 2003, the Lawn Care Borrower declared bankruptcy.  On April 1, 2004, the second of the Lawn Care Notes went into default.Although the Bank had perfected a security interest in equipment owned by the Lawn Care Borrower, that security interest was not transferred to Mr. Pacha upon his repayment of the first loan, which occurred prior to the date the Lawn Care Borrower filed bankruptcy. The second loan was unsecured per its terms and remained due and owing at the time that the Lawn Care Borrower filed bankruptcy. As a result, neither the Bank nor Mr. Pacha was a secured creditor at the time the Lawn Care Borrower filed bankruptcy. As a result, questions arose as to whether or not the Bank had a duty or had been requested to transfer the Banks security interest to Mr. Pacha upon his repayment of the first loan. The Bank and Director Pacha resolved all questions of liability relating to the Lawn Care Notes by an agreement dated July 26, 2005. Pursuant to the terms of this agreement, Mr. Pacha made a final payment on the second loan that, together with his final payment on the first loan, totaled
$68,377, and the Bank agreed to write off $3,768. Management believes that the terms of the agreement with Director Pacha are no less favorable to the Bank than the terms of similar agreements resolving similar loan situations in which a director was not involved.
