While it is difficult to determine the market value of shares owned by
nonaffiliates (within the meaning of such term under the applicable regulations
of the Securities and Exchange Commission), the Registrant estimates that the
aggregate market value of the Registrant's common stock held by nonaffiliates on
March 20, 2000 (based upon reports of beneficial ownership that approximately
80% of the shares are so owned by nonaffiliates and upon information
communicated informally to the Registrant by various purchasers and sellers that
the sale price for the common stock is generally $70 per share) was $83,773,000.

The number of shares outstanding of the Registrant's common stock as of March
20, 2000 is 1,495,941 shares of no par value common stock.

EXHIBIT INDEX

The exhibits index is on Page 67.





Part I

Item 1. Business

Hills Bancorporation (the "Company") is a multibank holding company principally
engaged in the business of banking. Its three wholly-owned subsidiary banks are
Hills Bank and Trust Company, Hills, Iowa ("Hills Bank and Trust"); Hills Bank,
Lisbon, Iowa ("Hills Bank Lisbon"); and Hills Bank Kalona, Kalona, Iowa ("Hills
Bank Kalona") (hereinafter collectively referred to as the "Banks").

The Company was incorporated December 12, 1982 and all operations are conducted
within the state of Iowa. The Company became owner of 100% of the outstanding
stock of Hills Bank and Trust as of January 23, 1984 when stockholders of Hills
Bank and Trust exchanged their shares for shares of the Company. Effective July
1, 1996, the Company acquired for cash all the outstanding shares of Hills Bank
Lisbon and on September 20, 1996, Hills Bank Kalona acquired cash, certain
assets and assumed the deposits of the Kalona, Iowa office of Boatmen's Bank
Iowa, N.A.

The Banks are all full-service commercial banks extending their services to
individuals, business, governmental units and institutional customers primarily
in the communities of Hills, Iowa City, Coralville, North Liberty, Lisbon, Mount
Vernon and Kalona and the surrounding area and most recently in Cedar Rapids.
This area includes parts of Johnson, Linn and Washington counties. All of the
Banks are actively engaged in all areas of commercial banking, including
acceptance of demand; savings and time deposits; making commercial, real estate,
agricultural and consumer loans; maintaining night and safe deposit facilities;
and performing collection, exchange and other banking services tailored for
individual customers. Hills Bank and Trust administers estates, personal trusts,
and pension and profit-sharing funds and, in connection therewith, provides for
farm management and investment advisory and custodial services for individuals,
corporations and nonprofit organizations. At this time, trust services are
available only at the Hills Bank and Trust locations. The loan activity of the
Banks is diversified, with commercial and agricultural loans, real estate loans,
automobile, installment and other consumer loans composing the majority of its
loan portfolio. In addition, the Banks earn substantial fees from originating
mortgages that are sold in the secondary residential real estate market without
mortgage servicing rights being maintained.

Each Bank has established formal loan origination policies. In general, the loan
origination policies require individual lenders to reduce the risk of credit
loss to the Bank by requiring that, among other things, minimum loan to value
ratios be maintained, evidence of appropriate levels of insurance be carried by
borrowers and documenting appropriate types and amounts of collateral and
sources of expected payment.

The Banks' business is not seasonal, except that loan origination fees are
higher during the spring and summer months. The Banks have not undertaken
significant new services during the current year that might exceed the limits of
their human resources and data processing capabilities.

Hills Bank and Trust serves the communities of Iowa City, Coralville, Hills and
North Liberty, located near Interstate 80 and Interstate 380 in Eastern Iowa.
The communities have a population of approximately 80,000 and Johnson County,
Iowa has a population of approximately 106,000. The University of Iowa has over
27,000 students and 23,000 full and part-time employees, including employees of
The University of Iowa Hospitals and Clinics. Johnson County, Iowa has one of
the strongest economies in Iowa and has had substantial economic growth in the
past ten years. Johnson County is known for its educational institutions, health
care facilities, cultural and sports events, and retail centers.





Hills Bank Lisbon has offices located in Lisbon, Iowa (Linn County) and Mount
Vernon, Iowa (Linn County), approximately 25 miles northeast of Iowa City and
does not conduct business in the same trade territories as Hills Bank and Trust.
Lisbon has a population of approximately 1,500 and Mount Vernon, located two
miles away, has a population of 3,700. Both communities are strong economically
and are easy commuting distances to Cedar Rapids and Iowa City, Iowa. In
addition, Mount Vernon is the home of Cornell College, which has approximately
1,200 students. In February 2000, Hills Bank Lisbon opened an office in downtown
Cedar Rapids, Iowa. Cedar Rapids has a metropolitan population of approximately
180,000 and is located approximately 10 miles west of Lisbon, Iowa.

Hills Bank Kalona is located in Kalona, Iowa (Washington County), approximately
20 miles south of Iowa City with a population of approximately 2,000 people.
Kalona is primarily an agricultural community, but is located within easy
driving distance for employment in Iowa City and Washington, Iowa.

The commercial banking business is highly competitive and the Banks compete with
other commercial banks, credit unions, brokerage firms, finance companies,
insurance companies and other financial institutions.

Iowa's banking laws regarding interstate banking and interstate branching are
currently more restrictive than many other states. As a result of the enactment
of the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 many
of the state-imposed geographic limitations on bank ownership have been
liberalized. The 1994 Act expanded opportunities for interstate banking,
interstate mergers and interstate branching in the United States. First, subject
to certain limitations, bank holding companies from anywhere in the United
States are able to acquire Iowa banks with the permission of the Federal Reserve
Board. Second, the 1994 Act authorizes a national or state bank which has its
main office in another state to merge with an Iowa bank and operate the Iowa
location as a branch office. However, out-of-state bank holding companies cannot
acquire Iowa commercial banks unless such banks have been in existence for at
least five years. Hills Bank Kalona has been in existence since September 20,
1996. Iowa also currently has a deposit concentration limit of 10% on the amount
of deposits that any one banking organization can control and continue to
acquire banks, which applies to both in-state and out-of-state banks. Iowa also
has a 35% limit on the aggregate amount of deposits all out-of-state banking
organizations can control within Iowa.

In recent years, Norwest Bank Iowa, N.A., Mercantile Bancorporation, Firstar
Corporation, Commercial Federal Bank and NationsBank have acquired a number of
independent banks and smaller multibank holding companies in various
metropolitan areas of Iowa. Each operates under a single charter in Iowa. In
September 1998, the Company's largest competing bank in Iowa City, with assets
of approximately $550 million, was acquired by Mercantile Bancorporation and
effective January 2000 the Mercantile banks in Iowa were merged into Firstar
Bank Iowa.





Iowa's intrastate branching statutes are also rather restrictive when compared
with those of other states. Generally, bank branch offices may only be operated
or acquired in counties contiguous to or cornering upon the county in which the
Bank has its principal place of business. Also, a bank in Iowa may not establish
a new branch office in a city in which there exists an office of another bank,
other than by acquisition of an existing office or bank. Effective July 1, 1998,
the number of bank branch offices allowed within a municipal corporation or an
urban complex is unlimited. However, some of Iowa's intrastate branching
limitations regarding geographic location of branch offices and the number of
branch offices which may be established in an urban complex or any other
location in Iowa may be overcome by merging two or more affiliated banking
organizations that have been in continuous operation in Iowa for at least five
years into a "united community bank."

In 1999 and 1998, three smaller banks from outlying communities in Johnson
County opened branches or De Novo banks in Iowa City or Coralville, and Brenton
Bank opened an office in Coralville. Similarly, several smaller banks have
recently began competing in the Cedar Rapids trade area.

The Financial Services Modernization Act ("FSMA") was enacted into law on
November 12, 1999. The most significant provision in this legislation is the
repeal of the restriction on banks affiliating with securities firms. The FSMA
would allow the creation of a "financial holding company" which can engage in a
number of financial activities including insurance and securities underwriting
and other agency activities, merchant banking and insurance company portfolio
investment activities. Activities that are ancillary to financial activities are
also allowed. Additionally, the FSMA amends the federal securities laws to
incorporate functional regulation of bank securities activities and provides for
the functional regulation of insurance activities by establishing which
insurance products banks and bank subsidiaries may provide as principal.
Furthermore, the FSMA provides reform in the Federal Home Loan Bank area by
providing that banks with less than $500 million in assets may use long-term
advances for loans to small businesses, small farms and small agri-businesses
and replaces the current $300 million funding formula for the REFCORP
obligations of the Federal Home Loan Banks to twenty percent (20%) of the Bank's
annual net earnings.

In the area of privacy, the FSMA requires clear disclosure by all financial
institutions of their privacy policy regarding the sharing of nonpublic
information with both affiliates and third parties. Further, the FSMA requires a
notice to consumers and an opportunity to "opt-out" of sharing of nonpublic
personal information with nonaffiliated third parties subject to certain limited
exceptions. The FSMA also provides reform in the areas of ATM's, Community
Reinvestment, Community Banks and Deposit Production Offices. Specifically, the
FSMA requires ATM operators who impose a fee for use of an ATM by a noncustomer
to post a notice on the machine that a fee will be charged and on the screen
that a fee will be charged and the amount of the fee, and further requires a
notice when ATM cards are issued that surcharges may be imposed by other parties
when transactions are initiated from ATM's not operated by the car issuer. The
FSMA also clarifies that nothing in the act repeals any provision of the
Community Reinvestment Act ("CRA"); however, the FSMA requires full disclosure
of all CRA agreements and grants regulatory relief regarding the frequency of
CRA exams to small banks and savings and loans (those with no more than $250
million in assets). In the community bank area, the FSMA allows community banks
all the powers as a matter of right that large institutions have accumulated on
an ad hoc basis, including the ability to underwrite municipal bonds in several
years. Finally, the FSMA expands the prohibition of deposit production offices
contained in the Reigle-Neal Interstate bill to include all branches of an
out-of-state bank holding company.





Hills Bank and Trust Company is in direct competition for deposits, loans and
other financial related business with other financial institutions in Johnson
County, Iowa. One of the largest competitors serving Johnson County is a branch
of Mercantile Bank, which does not disclose local assets. Other independent
financial institutions are:

Assets As Of
December 31,
1999
-------------
(In Millions)

Largest competing bank $ 382
Next largest competing bank 155
Largest competing credit union 185


Hills Bank Kalona and Hills Bank Lisbon compete with other banks in their trade
territories. Management estimates that these banks hold less than 40% of the
deposits in their respective communities.

No material portion of the Banks' deposits have been obtained from a single
person or a few persons. Accordingly, management of the Banks have no reason to
believe that the loss of the deposits of any person or few persons would have a
materially adverse effect on the Banks' operations or erode its deposit base.
Approximately 4.7% of the Banks' loans have been made for agricultural purposes.
The agricultural sector of the economy has been cyclical with a general trend
toward fewer and larger farms. The Banks have not experienced a material adverse
effect on their business as a result of defaults on agricultural loans and
expect none in the future.

The Company does not engage in any business activities apart from its ownership
of the Banks and, therefore, does not encounter any competition for its services
other than as described above for the Banks.

The Company and the Banks have undertaken no material research activities during
the last three years relating to research and development activities.

The Company is regulated by the Federal Reserve Bank.

All the Banks are regulated by the Federal Deposit Insurance Corporation and the
State of Iowa Division of Banking.

The Company had no employees as of December 31, 1999 and the Banks had 232
regular and 80 part-time employees.





The following consolidated statistical information reflects selected balances
and operations of the Company and the Banks for the periods indicated.

The following tables show (1) average balances of assets and liabilities, (2)
interest income and expense on a tax equivalent basis, (3) interest rates and
differential and (4) changes in interest income and expense.

============================================


(1) A significant portion of the commercial loans are six-month notes.
However, a significant amount of these notes are renewed when due.






NONACCRUAL, PAST DUE AND RESTRUCTURED LOANS

The following table summarizes the Company's nonaccrual, past due, restructured
and impaired loans as of December 31 for each of the years presented:



1999 1998 1997 1996 1995
---------------------------------------------
(In Thousands)

Nonaccrual loans .................. $ - - $ 12 $ - - $ 339 $ 489
Accruing loans past due
90 days or more ................ 1,320 945 954 1,092 417
Restructured loans
Impaired loans .................... 9,265 8,956 9,556 7,811 5,465


The Company does not have a significant amount of loans which are past due less
than 90 days on which there are serious doubts as to the ability of the
borrowers to comply with the loan repayment terms.

Loans are placed on nonaccrual status when management believes the collection of
future interest is not reasonably assured. Interest income was not materially
affected by this classification.

The Company has no individual borrower or borrowers engaged in the same or
similar industry exceeding 10% of total loans. The Company has no other
interest-bearing assets, other than loans, that meet the nonaccrual, past due,
restructured or potential problem loan criteria.

No allowance for losses has been recognized for impaired loans because partial
charge-offs have been taken to reduce the loan balances to the net present value
of the future cash flows or the fair value of the collateral if the loan is
collateral dependent.





SUMMARY OF LOAN LOSS EXPERIENCE

The following table summarizes the Company's loan loss experience for each of
the last five years:

==============================================
Ratio of net charge-offs during
year to average loans
outstanding ................... 0.00% 0.02% 0.09% 0.16% 0.06%
==============================================

The balance of the loan loss allowance has not been allocated by type of loan.
Management regularly reviews the loan portfolio and does not expect any unusual
material amount to be charged off during 2000 that would be significantly
different than the years ended December 31, 1999, 1998, 1997, 1996 and 1995.

(1) For financial reporting purposes, management regularly reviews the loan
portfolio and determines a provision for loan losses based upon the
impact of economic conditions on the borrower's ability to repay, past
collection experience, the risk characteristics of the loan portfolio and
such other factors which deserve current recognition. For income tax
purposes, the allowance is maintained at the maximum allowable amount.





ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES

The Banks review and place in risk categories specific borrowings. Based upon
the risk category assigned, the Banks allocate a percentage, as determined by
management, for a required allowance needed. The risk categories are similar to
those used by federal and state regulatory agencies and consist of the
following:

(1) Potential watch and watch
(2) Problem
(3) Substandard
(4) Doubtful

In addition, each bank's management also reviews and, where determined
necessary, allows for specific allowances based upon reviews of specific
borrowers and provides general allowances for areas which management believes
are of higher credit risk (agricultural loans and constructed model real estate
homes as of December 31, 1999).

A summary of the components of the allowance for loan loss, by risk category, as
of December 31, 1999 and 1998 is as follows:


1999 1998
------------------------------
(In Thousands)

Potential watch and watch loans .................. $ 3,164 $ 2,905
Substandard ...................................... 2,416 2,169
Specific borrowers (agricultural loans) .......... 1,025 1,048
Constructed model real estate homes .............. 925 969


Anticipated charge-offs of the above categories are not determinable at December
31, 1999; however, it is possible that agricultural loan charge-offs could be
higher in 2000 than the historical average due to lower farm commodity prices in
recent months.

Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations

Special Note Regarding Forward Looking Statements
- -------------------------------------------------

The discussion following contains certain forward-looking statements with
respect to the financial condition, the results of operations and business of
the Company. These statements involve certain risks and uncertainties which are
often inherent in the ongoing operation of financial institutions such as the
Company's subsidiary banks.

Forward-looking statements are typically identified by the words "believe,"
"expect," "anticipate," "target," "goal," "objective," "intend," "estimate" and
similar expressions.

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 as well as events and trends affecting
specific assets, the effect of credit quality and market perceptions of value on
the fair values of financial instruments and regulatory factors. These risks,
which are not inclusive, cannot be accurately estimated.

For example, a financial institution may accept deposits at fixed interest
rates, at different times and for different terms, and lend funds at fixed
interest rates, at different times and for different terms. In doing so, it
accepts the risk that its cost of funds may rise while the use of those funds
may be at a fixed rate. Similarly, although market rates of interest may
decline, the financial institution may have committed, by virtue of the term of
a deposit, to pay what essentially becomes an above-market rate.

Loans, and the allowance for loan losses, carry the risk that borrowers will not
repay all funds in a timely manner, as well as the risk of total loss. The
collateral pledged as security for loans may or may not have the value which has
been attributed to it. The loan loss reserve, while believed to be adequate, may
prove inadequate if one or more large-balance borrowers, or numerous mid-balance
borrowers, or a combination of both, experience financial difficulty for a
variety of reasons. These reasons may relate to the financial circumstances of
an individual borrower, or may be caused by negative economic circumstances of
an individual borrower, or may be caused by negative economic circumstances at
the local, regional, national or international level which are beyond the
control of the borrowers or the lender.

Because the business of banking is of a highly regulated nature, the decisions
of governmental entities can have a major effect on operating results.

All of these uncertainties, as well as others, are present in the operations and
business of the Company, and stockholders are cautioned that the Company's
actual results may differ materially from those included in the forward-looking
statements.

Total assets .......................... 773,966 689,787 603,102 539,452 484,607



In 1999, net loans increased $104.5 million, primarily in real estate mortgage
loans, as demand remained high and rates continued to be attractive. The large
increase in loans was primarily driven by a strong local economy, the sale of a
local competing bank and favorable interest rates. The 1998 loan growth of $38.2
million was also concentrated in real estate mortgage loans.

Total assets increased 12.20% in 1999, compared to an increase of 14.37% in
1998. The growth in assets in 1999 and 1998 was primarily attributable to strong
loan demand real estate mortgage loans.

Deposits increased 5.23% in 1999 compared to an increase of 11.33% in 1998. The
banks continued to compete for deposits in a market area where the total deposit
growth was weak. Federal Home Loan Bank note borrowings increased by a net $33
million in 1999 and $25 million in 1998 with the advances used to fund the loan
growth.

Income tax expense .............................. (2.39) (2.02) (1.71)
-------------------------------
Net income ........................ $ 5.66 $ 5.02 $ 4.78
===============================

In 1999, the increase in net income was due primarily to increased net interest
income, primarily resulting from a large increase in earning assets. The 1999
increase in noninterest income totaling $941,000 included increases in trust
fees ($286,000), deposit charges and fees ($375,000) and other charges and fees
($487,000).

The 1998 increase in net income resulted from increases in net interest income
and noninterest income, but was partially offset by higher noninterest expense.
Both noninterest income and noninterest expense for 1997 included the
recognition of a $1,054,000 gain on the contribution of a marketable equity
security to Hills Bancorporation Foundation, a private charitable foundation. As
a result of the stock contribution, Hills Bancorporation received an income tax
benefit of approximately $340,000, which reduced income tax expense.





The Company consistently benefited from low provisions for loan losses, a result
of a strong local economy and a loan portfolio that is concentrated in
well-secured real estate loans.

Net Interest Income
- -------------------

Net interest income is the excess of the interest and fees received on
interest-earning assets over the interest expense of the interest-bearing
liabilities. The measure is shown on a tax-equivalent basis to make the interest
earned on taxable and nontaxable assets more comparable.

Net interest income on a tax-equivalent basis changed in 1999 as follows:

========================

Loan Losses
- -----------

The provision for loan losses totaled $900,000, $916,000 and $1,048,000 for
1999, 1998 and 1997, respectively. Charge-offs, net of recoveries were $6,000
for 1999, $70,000 for 1998 and $349,000 for 1997.

The allowance for loan losses totaled $9,750,000 at December 31, 1999 compared
to $8,856,000 at December 31, 1998. The percentage of the allowance to
outstanding loans was 1.70% and 1.89% at December 31, 1999 and 1998,
respectively. The economy remains strong in the Banks' trade areas of Johnson,
Washington and Linn Counties, Iowa. Unemployment remains quite low in the Bank's
trade territory and, for the most part, area businesses have maintained stable
employment levels.

Agricultural loans totaled $27,302,000 at December 31, 1999. Management has
assessed the risks for agricultural loans higher than the other loans due to
unpredictable commodity prices, the effects of weather on crops and
uncertainties regarding government support programs. Therefore, the allowance
for loan losses includes general and specific reserves for these loans.

Loan concentrations, quality and loan terms had no other significant change in
1999 except that agricultural loans experienced a $5,000,000 decrease from 1999
and $100,000,000 of the 1999 loan growth was in real estate mortgages.
Therefore, the estimation methods and assumptions used in determining the 1999
allowance were consistent with 1998 and nearly all the additional allowance for
loan losses was allocated to new loans. Net loss experience for the past three
years has been consistently low, but the overall growth of the loan portfolio
results in a higher allowance for loan losses.

There are no known trends or uncertainties that are reasonably likely to have a
material effect on the allowance for loan losses in the near-term.

-----------------------------
$ 4.30 $ 3.90 $ 4.00
=============================

Other income for 1999 increased by $626,000 to $6,437,000. Loan origination fees
were $592,000 compared to $799,000 for 1998. The decrease is due primarily to
the fewer loan refinancing after interest rates increased in the second half of
1999. Trust fees increased $286,000 for the year to $2,029,000 due to more trust
assets under management. Deposit account charges and fees increased $375,000 for
1999 and other fees and charges increased $487,000. Other income was reduced for
1999 by $315,000, which represented investment securities losses taken to
replace lower yielding securities with higher yielding securities of similar
risk and maturity.

In 1998, total other income increased $967,000 on a comparable basis to 1997
after adjusting for investment securities gain in 1997 of $940,000 and $154,000
gain on the sale of the student loan portfolio. Due to the lower interest rate
environment in 1998, loan origination fees increased $412,000 over the 1997
amount of $387,000. In addition, trust fees increased $380,000 due to new
accounts and higher balances under management.

=============================

Other expenses for 1999 increased to $18,309,000 from $16,438,000 in 1998.
Salaries and benefits accounted for $1,200,000 of the increase for the year.
This is a result of new staff additions during 1999 including staff for the new
branch, salary adjustments in January 1999 and significant increases in medical
insurance claims in 1999 compared to 1998. All other expenses increased from
$7,863,000 in 1998 to $8,502,000 for the year ended December 31, 1999. The major
category that increased was furniture and equipment, which was $1,687,000 in
1998 and $1,893,000 in 1999 and was the result of depreciation and amortization
of major computer hardware and software additions in 1999 and late 1998.





Salaries and benefits increased $1,457,000 in 1998 compared to 1997. The Banks
have added positions in the retail sector of the Banks, including the Trust
Department, as a result of increased business. At the end of 1998, full time
equivalent employees totaled 253, an increase of 30 since December 31, 1997.
Included in the 1998 increase are new personnel located at the Mount Vernon
office of Hills Bank Lisbon, which opened in February 1998. Occupancy and
furniture and equipment expenses increased $378,000 in 1998, or 15.45% over 1997
due to depreciation on the new office in Mount Vernon, a new computer hardware
and software system installed in the first quarter of 1998, and expenses related
to the Year 2000 computer changes which totaled approximately $88,000.

Income Taxes
- ------------

Income tax expense was $3,570,000, $3,006,000 and $2,545,000 for the years ended
December 31, 1999, 1998 and 1997, respectively. The corresponding percentage of
income taxes compared to income before income taxes is 29.66% in 1999, 28.65% in
1998 and 26.40% in 1997. Income tax expense for 1997 was 26.4% of pretax income,
compared to an average of 29.16% for other years, due to contributions.

Impact of Recently Issued Accounting Standards
- ----------------------------------------------

Recently issued accounting standards are summarized below.

Statement No. 133 on derivatives will, in 2000, require all derivatives to be
recorded at fair value in the balance sheet, with changes in fair value run
through income. If derivatives are documented and effective as hedges, the
change in the derivative fair value will be offset by an equal change in the
fair value of the hedged item.

This standard is not expected to have a material effect on future financial
statements.

A portion of the interest-bearing checking, savings and money market accounts
has been included in the above table as maturing immediately based upon
management's estimate using a financial model and the rest of these deposits are
shown as more than one year. The classifications are used because the Banks'
historical data indicates that these have been very stable deposits without much
interest rate fluctuation. Historically, these accounts would not need to be
adjusted upward as quickly in a period of rate increases so the interest risk
exposure would be less than the repricing schedule indicates.




Inflation
- ---------

Inflation has an impact on the growth of total assets and has resulted in the
need to increase equity capital to maintain an appropriate equity to asset
ratio. The results of operations have been affected by inflation, but the effect
has been minimal.

Liquidity and Capital Resources
- -------------------------------

On an unconsolidated basis, Hills Bancorporation (the holding company) had cash
balances of $1,419,000 as of December 31, 1999. In 1999, the holding company
received dividends of $1,911,000 from its subsidiary banks and used those funds
to pay dividends to its stockholders of $1,910,000.

As of December 31, 1999 and 1998, stockholders' equity before deducting for the
maximum cash obligation related to ESOP was $71,217,000 and $65,753,000,
respectively. This measure of equity as a percent of total assets was 9.20% at
December 31, 1999 and 9.53% at December 31, 1998. These ratios are comparable
with the Company's peers. As of December 31, 1999, total equity was 7.79% of
assets compared to 8.18% of assets at the prior year end. The ability of the
Company to pay dividends to its shareholders is dependent upon the earnings and
capital adequacy of the subsidiaries banks, which affects the Banks' dividends
to the Company. The Banks are subject to certain statutory and regulatory
restrictions on the amount they may pay in dividends. In order to maintain
acceptable capital ratios in the subsidiary banks, certain of their retained
earnings are not available for the payment of dividends. Retained earnings
available for the payment of dividends to the Company total approximately
$4,032,000 as of December 31, 1999.

The Company and the Banks are subject to the Federal Deposit Insurance
Corporation Improvement Act of 1991 and the Banks are subject to Prompt
Corrective Action Rules as determined and enforced by the Federal Reserve. These
regulations establish minimum capital requirements which member banks must
maintain.

As of December 31, 1999, risk-based capital standards require 8% of
risk-weighted assets. At least half of that 8% must consist of Tier I core
capital (common stockholders' equity, noncumulative perpetual preferred stock
and minority interest in the equity accounts of consolidated subsidiaries), and
the remainder may be Tier II supplementary capital (perpetual debt,
intermediate-term preferred stock, cumulative perpetual, long-term and
convertible preferred stock, and loan loss reserve up to a maximum of 1.25% of
risk-weighted assets). Total risk-weighted assets are determined by weighing the
assets according to their risk characteristics. Certain off-balance sheet items
(such as standby letters of credit and firm loan commitments) are multiplied by
"credit conversion factors" to translate them into balance sheet equivalents
before assigning them risk weightings. Any bank having a capital ratio less than
the 8% minimum required level must, within 60 days, submit to the Federal
Reserve a plan describing the means and schedule by which the Bank shall achieve
the applicable minimum capital ratios.





Each of the Banks is an insured state bank, incorporated under the laws of the
state of Iowa. As such, the Banks are subject to regulation, supervision and
periodic examination by the Superintendent of Banking of the State of Iowa (the
"Superintendent"). Among the requirements and restrictions imposed upon state
banks by the Superintendent are the requirements to maintain reserves against
deposits, restrictions on the nature and amount of loans which may be made by
state banks, and restrictions relating to investments, opening of bank offices
and other activities of state banks. Changes in the capital structure of state
banks must also be approved by the Superintendent. One of the most significant
standards of operation of state banks is the six and one-half percent (6 1/2%)
primary capital to total assets ratio generally required by the Superintendent.
This ratio was reduced in 1999 from the eight percent (8%) ratio formerly
required. In certain instances, the Superintendent may mandate higher capital,
but the Superintendent has not imposed such a requirement on the Bank. The
Superintendent defines the term "primary capital" to mean the sum of
stockholders' equity and the allowance for loan losses less any intangible
assets. In determining the primary capital ratio, the Superintendent uses the
total assets as of the date of computation. At December 31, 1999, the primary
capital to total assets ratio of each of the Banks exceeded the ratio required
by the Superintendent.

A comparison of the Company's capital as of December 31, 1999 with minimum
requirements is presented below:


Minimum
Actual Requirements
--------------------------------

Tier I Risk-Based Capital ....................... 13.2% 4%
Total Risk-Based Capital ........................ 14.47 8
Leverage Ratio .................................. 9.56 3

Each of the Banks is classified as "well capitalized" by FDIC capital
guidelines.

On a consolidated basis, 1999 cash flows from operations provided $10,844,000,
net increases in deposits provided $27,935,000 and Federal Home Loan Bank
borrowings provided $32,968,000. These cash flows were invested in net loans of
$105,370,000, net securities of $10,937,000 and net federal funds sold decrease
of $36,605,000. In addition, $1,937,000 was used to purchase property and
equipment.

At December 31, 1999, the Company had total outstanding loan commitments of
$83,894,000. Management believes that its liquidity levels are sufficient, but
the Company may slow down the growth of its assets by selling more loans in the
secondary market or by selling portions of loans to other banks through
participation agreements.

Commitments and Trends
- ----------------------

The Company has no material commitments or plans which will materially affect
its liquidity or capital resources. Property and equipment may be acquired in
cash purchases, or they may be financed if favorable terms are available.

Year 2000
- ---------

Like other financial service providers and business organizations, the Company
took appropriate measures in advance of the calendar change on January 1, 2000
to ensure its application software programs and operating systems would
accommodate this date value. Beginning in 1997, the Company began carrying out a
plan to address the "Y2K" issue. All systems were examined to determine the
extent and complexity of their vulnerability. Evaluations included hardware,
software, mechanical and other critical systems.

In each case where a potential problem was identified, action was taken to
address it by replacing or upgrading the system affected. All critical systems
were tested by simulating Year 2000 operating conditions and verifying the
results of those tests. Contingency plans were developed to ensure operations
would continue in the unlikely event a system failed. The Company employed
verification procedures during the century rollover period and encountered no
problems to any of its systems.

The Company's plans included communications to and evaluation of significant
borrowers to assess their readiness and determine if loan payments could be
delayed due to Year 2000 problems. To date, the Company has not experienced any
loan losses, nor does it anticipate future losses, related to this issue.

Total capitalized hardware and software costs of the Year 2000 project in 1999
and 1998 were approximately $136,000 and $1,180,000, respectively. Expenses
charged to earnings for the Year 2000 project in 1999 and 1998 were $88,000 and
$105,000, respectively. In addition, the Company estimates the opportunity cost
of maintaining additional cash reserves have been $66,000 in 1999.





PART II

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market Risk Exposures
- ---------------------

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 rates increase
over an extended period of time. Inversely, 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.

The Banks maintain an asset/liability committee which meets at least quarterly
to review the interest rate sensitivity position and to review various
strategies as to interest rate risk management. In addition, the Banks use a
simulation model to review various assumptions relating to interest rate
movement. The model attempts to limit rate risk even if it appears the Banks'
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 repriced rapidly.

Based on the data following, net interest income should decline with
instantaneous increases in interest rates while net interest income should
increase with instantaneous declines in interest rates. Generally, during
periods of increasing interest rates, the Company's interest rate sensitive
liabilities would reprice faster than its interest rate sensitive assets causing
a decline in the Company's interest rate spread and margin. This would result
from an increase in the Company's cost of funds that would not be immediately
offset by an increase in its yield on earning assets which would tend to reduce
net interest income. In times of decreasing interest rates, fixed rate assets
could increase in value and the lag in repricing of interest rate sensitive
assets could be expected to have a positive effect on the Company's net interest
income.

The following table provides quantitative information with respect to interest
sensitive assets and liabilities.

HILLS BANCORPORATION

NOTES TO FINANCIAL STATEMENTS

- --------------------------------------------------------------------------------


Note 1. Nature of Activities and Significant Accounting Policies

Nature of activities: Hills Bancorporation (the "Company") is a multibank
holding company engaged in the business of banking. The Company's three
wholly-owned subsidiary commercial banks are Hills Bank and Trust Company,
Hills, Iowa, Hills Bank, Lisbon, Iowa, and Hills Bank Kalona, Kalona, Iowa. The
Banks are all full-service commercial banks extending their services to
individuals, businesses, governmental units and institutional customers
primarily in the communities of Hills, Iowa City, Coralville, North Liberty,
Lisbon, Mount Vernon, Kalona and Cedar Rapids, Iowa.

The Banks compete with other financial institutions and nonfinancial
institutions providing similar financial products. Although the loan activity of
the Banks is diversified with commercial and agricultural loans, real estate
loans, automobile, installment and other consumer loans, each Bank's credit is
concentrated in real estate loans.

Accounting estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Certain significant estimates: The allowance for loan losses, fair values of
securities and other financial instruments, and stock-based compensation expense
involve certain significant estimates made by management. These estimates are
reviewed by management routinely and it is reasonably possible that
circumstances that exist at December 31, 1999 may change in the near-term future
and that the effect could be material to the consolidated financial statements.

Principles of consolidation: The consolidated financial statements include the
accounts of the Company and its subsidiaries, which are wholly-owned. All
significant intercompany balances and transactions have been eliminated in
consolidation.

Investment securities: Held-to-maturity securities consist solely of debt
securities which the Company has the positive intent and ability to hold to
maturity and are stated at amortized cost.

Available-for-sale securities consist of debt securities not classified as
trading or held to maturity. Available-for-sale securities are stated at fair
value, and unrealized holding gains and losses, net of the related deferred tax
effect, are reported as a separate component of stockholders' equity. There were
no trading securities as of December 31, 1999 and 1998.

Stock of the Federal Home Loan Bank is carried at cost.

Premiums and discounts on debt securities are amortized over the contractual
lives of those securities. The method of amortization results in a constant
effective yield on those securities (the interest method). Realized gains and
losses on investment securities are included in income, determined on the basis
of the cost of the specific securities sold.

Loans: Loans are stated at the amount of unpaid principal, reduced by the
- ----- allowance for loan losses.

The allowance for loan losses is established through a provision for loan losses
charged to expense. Loans are charged against the allowance when management
believes the collectability of principal is unlikely. The allowance for loan
losses is maintained at a level considered adequate to provide for losses that
can be reasonably anticipated. The allowance is increased by provisions charged
to expense and is reduced by net charge-offs. The Banks make continuous reviews
of the loan portfolio and considers current economic conditions, historical loss
experience, review of specific problem loans and other factors in determining
the adequacy of the allowance.

Loans are considered impaired when, based on current information and events, it
is probable the Banks will not be able to collect all amounts due. The portion
of the allowance for loan losses applicable to impaired loans has been computed
based on the present value of the estimated future cash flows of interest and
principal discounted at the loans effective interest rate or on the fair value
of the collateral for collateral dependent loans. The entire change in present
value of expected cash flows of impaired loans or of collateral value is
reported as bad debt expense in the same manner in which impairment initially
was recognized or as a reduction in the amount of bad debt expense that
otherwise would be reported. Interest income on impaired loans is recognized on
the cash basis.


The accrual of interest income on loans is discontinued when, in the opinion of
management, there is reasonable doubt as to the borrower's ability to meet
payments of interest or principal when they become due.

Loan fees and origination costs are reflected in the statement of income as
collected or incurred. Compared to the net deferral method, this practice had no
significant effect on income.

Transfers of financial assets: Transfers of financial assets are accounted for
as sales, when control over the assets has been surrendered. Control over
transferred assets is deemed to be surrendered when (1) the assets have been
isolated from the Company, (2) the transferee obtains the right (free of
conditions that constrain it from taking advantage of that right) to pledge or
exchange the transferred assets and (3) the Company does not maintain effective
control over the transferred assets through an agreement to repurchase them
before their maturity.

Credit related financial instruments: In the ordinary course of business, the
Company has entered into commitments to extend credit, including commitments
under credit card arrangements, commercial letters of credit and standby letters
of credit. Such financial instruments are recorded when they are funded.

Property and equipment: Property and equipment is stated at cost less
accumulated depreciation. Depreciation is computed using primarily
declining-balance methods over the estimated useful lives of 7-40 years for
buildings and improvements and 3-20 years for furniture and equipment.

Deferred income taxes: Deferred income taxes are provided under the liability
method whereby deferred tax assets are recognized for deductible temporary
differences and net operating loss, and tax credit carryforwards and deferred
tax liabilities are recognized for taxable temporary differences. Temporary
differences are the differences between the reported amounts of assets and
liabilities and their tax bases. Deferred tax assets are reduced by a valuation
allowance when, in the opinion of management, it is more likely than not that
some or all of the deferred tax assets will not be realized. Deferred tax assets
and liabilities are adjusted for the effects of changes in tax laws and rates on
the date of enactment.

Intangible assets: Intangible assets consist principally of goodwill which
represents the excess of cost over fair value of net assets acquired in business
combinations of two banks in 1996 accounted for under the purchase method.
Goodwill is amortized on a straight-line basis over the estimated period to be
benefited, 15 years. The carrying value of goodwill is reviewed periodically for
impairment. Goodwill totaled $3,021,000 and $3,282,000, net of accumulated
amortization of $876,000 and $615,000 as of December 31, 1999 and 1998 and is
included in other assets.

Stock options: Compensation expense for stock issued through stock option and
award plans is accounted for using the intrinsic value based method of
accounting prescribed by APB Opinion No. 25, "Accounting for Stock Issued to
Employees." Under this method, compensation is measured as the difference
between the estimated fair value of the stock at the date of award less the
amount required to be paid for the stock. The difference, if any, is charged to
expense over the periods of service.

Common stock held by ESOP: The Company's maximum cash obligation related to
these shares is classified outside stockholders' equity because the shares are
not readily traded and could be put to the Company for cash.

Trust assets: Trust assets, other than cash deposits, held by the Banks in
fiduciary or agency capacities for its customers are not included in these
statements since they are not assets of the Company.

Earnings per share: Basic per-share amounts are computed by dividing net income
(the numerator) by the weighted-average number of common shares outstanding (the
denominator). Diluted per share amounts assume the conversion, exercise or
issuance of all potential common stock unless the effect is to reduce the loss
or increase the income per common share from continuing operations.

Following is a reconciliation of the denominator:


Year Ended December 31,
---------------------------------------------
1999 1998 1997
---------------------------------------------

Weighted average number of shares ........................... 1,483,540 1,467,772 1,465,914
Potential number of dilutive shares ......................... 11,784 22,702 18,040
---------------------------------------------
Total shares to compute diluted earnings per share .......... 1,495,324 1,490,474 1,483,954
=============================================


There are no potentially dilutive securities that have not been included in the
determination of diluted shares.


Statement of cash flows: 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 loans originated by the Banks, deposits
and federal funds purchased and sold are reported net.

Recently issued accounting standards:

Recently issued accounting standards are not expected to materially affect the
Company's financial statements.

Fair value of financial instruments: In cases where quoted market prices are not
available, fair values of financial instruments are based on estimates using
present value or other valuation techniques. Those techniques are significantly
affected by the assumptions used, including the discount rate and estimates of
future cash flows. In that regard, the derived fair value estimates cannot be
substantiated by comparison to independent markets and, in many cases, could not
be realized in immediate settlement of the instrument. Certain financial
instruments and all nonfinancial instruments are excluded from fair value
disclosure. Accordingly, the aggregate fair value amounts presented in Note 11
do not represent the underlying value of the Company.

The following methods and assumptions were used by the Company in estimating the
fair value of its financial instruments:

Off-balance sheet instruments: Fair values for outstanding letters of credit
are based on fees currently charged to enter into similar agreements, taking
into account the remaining terms of the agreements and the counterparties'
credit standing. The fair value of the outstanding letters of credit is not
believed to be significant. Unfunded loan commitments are not valued since
the loans are generally priced at market at the time of funding.

Cash and cash equivalents and federal funds sold: The carrying amounts
reported in the balance sheet for cash and short-term instruments approximate
their fair values.

Investment securities: Fair values for investment securities are based on
quoted market prices, where available. If quoted market prices are not
available, fair values are based on quoted market prices of comparable
instruments.

Loans receivable: For variable-rate loans that reprice frequently and with no
significant change in credit risk, fair values are based on carrying values.
The fair values for other loans are determined using estimated future cash
flows, discounted at the interest rates currently being offered for loans
with similar terms to borrowers with similar credit quality. The carrying
amount of accrued interest receivable approximates its fair value.

Deposit liabilities: The fair values of demand deposits equal their carrying
amounts which represent the amount payable on demand. The carrying amounts
for variable-rate, fixed-term money market accounts and certificates of
deposit are estimated using a discounted cash flow calculation that applies
interest rates currently being offered on certificates to a schedule of
aggregated expected monthly maturities on time deposits.

Short-term borrowings: The carrying amounts of borrowings under repurchase
agreements approximate their fair values.

Long-term borrowings: The fair values of the Banks' long-term borrowings
(other than deposits) are estimated using discounted cash flow analyses,
based on the Banks' current incremental borrowing rates for similar types of
borrowing arrangements.

amount of $135,875,000. As of December 31, 1999, the Company held Federal Home
Loan Bank stock with a cost of $5,930,000.

Note 7. Employee Benefit Plans

The Company has an Employee Stock Ownership Plan (the "ESOP") to which it makes
discretionary cash contributions. The Company's contribution to the ESOP totaled
$64,000, $58,000 and $49,000 for the years ended December 31, 1999, 1998 and
1997, respectively.

In the event a terminated plan participant desires to sell his or her shares of
the Company stock, or for certain employees who elect to diversify their account
balances, the Company may be required to purchase the shares from the
participant at their fair value. To the extent that shares of common stock held
by the ESOP are not readily traded, a sponsor must reflect the maximum cash
obligation related to those securities outside of stockholders' equity. As of
December 31, 1999, 156,474 shares held by the ESOP, at a fair value of $70 per
share, have been reclassified from stockholders' equity to liabilities.




The Company has a profit-sharing plan with a 401(k) feature which provides for
discretionary annual contributions in amounts to be determined by the Board of
Directors. The profit-sharing contribution totaled $509,000, $461,000 and
$394,000 for the years ended December 31, 1999, 1998 and 1997, respectively.

The Company has a Stock Incentive Plan for certain key employees and directors
whereby shares of common stock have been reserved for awards in the form of
stock options or stock awards. A Stock Option Committee may grant options at
prices equal to the fair value of the stock at the date of the grant. Options
expire 10 years from the date of the grant. Directors may exercise options
immediately and officers' rights under the plan vest over a five-year period
from the date of the grant. Additional compensation is accrued equivalent to the
amount of dividends that would have been paid on the stock had the options been
exercised. Such compensation is payable upon exercise of the options. No
compensation expense has been charged to expense using the intrinsic value based
method as prescribed by APB No. 25. Had compensation expense been determined
based on the grant date fair values of the awards, as prescribed by SFAS No.
123, reported net income and earnings per share would have been as follows:


Years Ended December 31,
--------------------------
1999 1998 1997
--------------------------

Pro forma net income (in thousands) ........... $ 8,461 $ 7,481 $ 7,084
Pro forma earnings per share:
Basic ...................................... 5.70 5.10 4.83
Diluted .................................... 5.66 5.02 4.77


The pro forma effects of applying SFAS are not indicative of future amounts
since, among other reasons, the pro forma requirements of SFAS No. 123 have been
applied only to options granted after December 31, 1994.

The fair value of each grant is established at the grant date using the
Black-Scholes option-pricing model with the following weighted average
assumptions for grants in 1997: Dividend rate 2.19%; price volatility of 4.64%;
risk-free interest rate of 6.63% and an expected life of 5 years.

A summary of the stock options is as follows:

As of December 31, 1999, no options were available for future grants.

The committee is also authorized to grant awards of common stock and authorized
the issuance of 1,587, 902 and 938 shares of common stock to a group of
employees in 1999, 1998 and 1997, respectively.

Note 9. Regulatory Capital Requirements, Restrictions on Subsidiary
Dividends and Cash Restrictions

Federal regulatory agencies have adopted various capital standards for financial
institutions, including risk-based capital standards. The primary objectives of
the risk-based capital framework are to provide a more consistent system for
comparing capital positions of financial institutions and to take into account
the different risks among financial institutions' assets and off-balance sheet
items.

Risk-based capital standards include requirements for a minimum Tier 1 capital
to assets ratio (leverage ratio). In addition, regulatory agencies consider the
published capital levels as minimum levels and may require a financial
institution to maintain capital at higher levels.

A comparison of the Company's capital as of December 31, 1999 with the minimum
requirements is presented below.

Minimum
Actual Requirements
--------------------------------
Tier 1 Risk-Based Capital ....................... 13.21% 4.00%
Total Risk-Based Capital ........................ 14.47% 8.00%
Leverage Ratio .................................. 9.56% 3.00%


According to FDIC capital guidelines, each of the Banks is classified as "Well
Capitalized." The ability of the Company to pay dividends to its stockholders is
dependent upon dividends paid by the Banks. The Banks are subject to certain
statutory and regulatory restrictions on the amount they may pay in dividends.
To maintain acceptable capital ratios in the Banks, certain of their retained
earnings are not available for the payment of dividends. To maintain a ratio of
capital to assets of 8%, retained earnings of $4,032,000 as of December 31, 1999
are available for the payment of dividends to the Company.

Each of the Banks is required to maintain reserve balances in cash or with the
Federal Reserve Bank. Reserve balances totaled $7,938,000 and $5,783,000 as of
December 31, 1999 and 1998, respectively.


Note 10. Related Party Transactions

Certain directors of the Company and the Banks and companies with which the
directors are affiliated and certain principal officers are customers of, and
have banking transactions with, the Banks in the ordinary course of business.
Such indebtedness has been incurred on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with unrelated persons.

The following is an analysis of the changes in the loans to related parties
during the years ended December 31, 1999 and 1998:

Year Ended December 31,

============================

Deposits from related parties are accepted subject to the same interest rates
and terms as those from nonrelated parties.

=================================



Concentrations of credit risk: All of the Banks' loans, commitments to extend
credit, unused lines of credit and outstanding letters of credit have been
granted to customers within each Bank's market area. Investments in securities
issued by state and political subdivisions within the state of Iowa totaled
approximately $15,898,000. The concentrations of credit by type of loan are set
forth in Note 3. Outstanding letters of credit were granted primarily to
commercial borrowers. Although the Banks have a diversified loan portfolio, a
substantial portion of its debtors' ability to honor their contracts is
dependent upon the economic conditions in Johnson County, Iowa.

Contingencies: In the normal course of business, the Banks are involved in
various legal proceedings. In the opinion of management, any liability resulting
from such proceedings would not have a material adverse effect on the
accompanying financial statements.

Financial instruments with off-balance sheet risk: The Banks are parties to
financial instruments with off-balance sheet risk in the normal course of
business to meet the financing needs of their customers. These financial
instruments include commitments to extend credit, credit card participations and
standby letters of credit. These instruments involve, to varying degrees,
elements of credit risk in excess of the amount recognized in the balance
sheets.





Note 13. Commitments and Contingencies (Continued)

The Banks' exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for commitments to extend credit, credit card
participations and standby letters of credit is represented by the contractual
amount of those instruments. The Banks use the same credit policies in making
commitments and conditional obligations as they do for on-balance sheet
instruments. A summary of the Banks' commitments at December 31, 1999 and 1998
is as follows:

1999 1998
------------------------
(Amounts In Thousands)
Firm loan commitments and unused portion of
lines of credit:
Home equity loans .................................... $ 3,628 $ 3,509
Credit card participations ........................... 10,695 8,689
Commercial, real estate and home construction ........ 35,882 27,549
Commercial lines ..................................... 33,689 54,173
Outstanding letters of credit ........................... 10,711 10,571


Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Since many
of the commitments are expected to expire without being drawn upon, the total
commitment amounts do not necessarily represent future cash requirements. The
Banks evaluate each customer's credit worthiness on a case-by-case basis. The
amount of collateral obtained, if deemed necessary by the Bank upon extension of
credit, is based on management's credit evaluation of the party. Collateral held
varies, but may include accounts receivable, crops, livestock, inventory,
property and equipment, residential real estate and income-producing commercial
properties. Credit card participations are the unused portion of the holders'
credit limits. Such amounts represent the maximum amount of additional unsecured
borrowings.

Outstanding letters of credit are the conditional commitments issued by the
Banks to guarantee the performance of a customer to a third party and
collateralize the customer's borrowing arrangement with other creditors. The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loan facilities to customers. Collateral held varies
as specified above and is required in instances which the Banks deem necessary.
