                   AMES NATIONAL CORPORATION AND SUBSIDIARIES

             Notes to Consolidated Financial Statements (Unaudited)



1. Significant Accounting Policies

The consolidated financial statements for the three and nine-month periods ended
September 30, 2003 and 2002 are  unaudited.  In the opinion of the management of
Ames National  Corporation (the "Company"),  these financial  statements reflect
all  adjustments,  consisting only of normal  recurring  accruals,  necessary to
present  fairly  these  consolidated   financial  statements.   The  results  of
operations  for the interim  periods are not  necessarily  indicative of results
which may be expected  for an entire  year.  Certain  information  and  footnote
disclosure  normally  included  in  complete  financial  statements  prepared in
accordance with generally  accepted  accounting  principles have been omitted in
accordance with the requirements for interim financial  statements.  The interim
financial  statements and notes thereto  should be read in conjunction  with the
year-end  audited  financial  statements  contained in the Company's  10-K.  The
consolidated  condensed financial statements include the accounts of the Company
and  its  wholly-owned  banking  subsidiaries  (the  "Banks").  All  significant
intercompany balances and transactions have been eliminated in consolidation.

2. Dividends

On November 12, 2003, the Company  declared a cash dividend on its common stock,
payable on February 16, 2004 to  stockholders  of record as of February 2, 2004,
equal to $0.46 per share.

3. Earnings Per Share

Earnings per share amounts were  calculated  using the weighted  average  shares
outstanding  during the periods  presented.  The  weighted  average  outstanding
shares for the three months ended September 30, 2003 and 2002 were 3,133,053 and
3,128,982,  respectively.  The weighted average  outstanding shares for the nine
months  ended  September  30,  2003  and  2002  were  3,130,607  and  3,126,714,
respectively.

4. Commitments

In  the  normal  course  of  business,  the  Company  enters  into a  number  of
off-balance sheet  commitments.  These commitments expose the Company to varying
degrees of credit and market risk and are subject to the same credit  reviews as
those recorded on the balance sheet.

The Company enters into  commitments  to extend credit such as loan  commitments
and standby letters of credit to meet the financing needs of its customers.  For
additional  information  on  credit  extension  commitments  see  Note  9 of the
Company's 2002 consolidated  financial statements.  The Company's commitments as
of September 30, 2003 and December 31, 2002 are approximately as follows:

                                          September 30, 2003   December 31, 2002
                                          --------------------------------------

Commitments to extend credit ...........      $60,600,000         $59,410,000
Standby letters of credit ..............        1,330,000           1,490,000
                                              -------------------------------
                                              $61,930,000         $60,900,000
                                              ===============================

5. Impact of New Financial Accounting Standards

Financial  Accounting  Standards Board Interpretation (FIN) No. 45, "Guarantor's
Accounting  and  Disclosure  Requirements  for  Guarantees,  Including  Indirect
Guarantees of Indebtedness of Others - an  Interpretation of FASB Statements No.
5, 57 and 107 and Rescission of FASB Interpretation No 34." FIN 45 elaborates on
the  disclosures  to be made by a guarantor in its interim and annual  financial
statements about its obligations under certain guarantees that it has issued. It
also clarifies that a guarantor is required to recognize,  at the inception of a
guarantee,  a  liability  for the fair  value of the  obligation  undertaken  in
issuing the guarantee. The initial recognition and measurement provisions of FIN
45 are applicable on a prospective  basis to guarantees issued or modified after
December 31, 2002.  The  disclosure  requirements  of FIN 45 are  effective  for
financial  statements  of interim or annual  periods  ending after  December 15,
2002, and were adopted in the  Corporation's  financial  statements for the year
ended December 31, 2002. Implementation of the remaining provisions of FIN 45 on
January 1, 2003 did not have a significant impact of the Corporation's financial
statements.


                                       6


In  January  2003,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Interpretation No. 46 ("FIN 46"), "Consolidated Variable Interest Entities". The
objective  of the  Interpretation  is to provide  guidance  on how to identify a
variable   interest   entity  and  determine   when  the  assets,   liabilities,
non-controlling  interests,  and results of operations of a variable interest in
an entity need to be included in a company's  consolidated financial statements.
A company that holds  variable  interests in an entity will need to  consolidate
the entity if the  company's  interest in the variable  interest  entity is such
that the company will absorb a majority of the variable interest entity's losses
and/or receive a majority of the entity's  expected  residual  returns,  if they
occur. FIN 46 also required additional  disclosures by primary beneficiaries and
other   significant   variable   interest   holders.   The  provisions  of  this
interpretation  are effective upon issuance.  The Company is not impacted by the
provisions of FIN 46.

In April 2003,  the FASB issued  Statement No. 149,  "Amendment of Statement No.
133,  Accounting  for  Derivative  Instruments  and  Hedging  Activities."  This
statement  clarifies the  definition of a derivative  and  incorporates  certain
decisions  made by the  Board  as part of the  Derivative  Implementation  Group
process. This statement is effective for contracts entered into or modified, and
for hedging  relationships  designated after June 30, 2003 and should be applied
prospectively. The Company is not impacted by this Statement.

SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics
for both  Liabilities  and Equity."  SFAS 150  established  standards for how an
issuer  classifies,  measures and discloses in its financial  statements certain
financial instruments with characteristics for both liabilities and equity. SFAS
150 requires that an issuer classify  financial  instruments that are within its
scope as liabilities, in most circumstances.  Such financial instruments include
(i)  financial  instruments  that  are  issued  in the form of  shares  that are
mandatorily redeemable;  (ii) financial instruments that embody an obligation to
repurchase the issue's equity shares, or are indexed to such an obligation,  and
that require the issue to settle the obligation by  transferring  assets;  (iii)
financial  instruments  that embody an obligation  that the issuer may settle by
issuing a variable  number of its equity shares if, at  inception,  the monetary
value of the obligation is predominantly based on a fixed amount,  variations in
something  other than the fair value of the issuer's equity shares or variations
inversely  related to changes in the fair value of the issuer's  equity  shares;
and (iv) certain freestanding financial  instruments.  SFAS 150 is effective for
contracts  entered  into or  modified  after  May  31,  2003,  and is  otherwise
effective at the beginning of the first interim period  beginning after June 15,
2003.  Adoption of SFAS 150 on July 1, 2003 did not have a significant impact on
the Corporation's financial statements.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements about the
Company,  its  business and its  prospects.  Forward-looking  statements  can be
identified by the fact that they do not relate strictly to historical or current
facts.  They often include use of the words "believe",  "expect",  "anticipate",
"intend",  "plan",  "estimate"  or  words  of  similar  meaning,  or  future  or
conditional  verbs  such  as  "will",  "would",   "should",  "could"  or  "may".
Forward-looking   statements,   by  their  nature,  are  subject  to  risks  and
uncertainties.  A number of  factors,  many of which are  beyond  the  Company's
control,   could  cause   actual   conditions,   events  or  results  to  differ
significantly from those described in the forward-looking statements. Such risks
and  uncertainties  with  respect to the Company  include  those  related to the
economic  environment,  particularly  in the areas in which the  Company and the
Banks operate, competitive products and pricing, fiscal and monetary policies of
the U.S.  government,  changes in governmental  regulations  affecting financial
institutions,  including  regulatory fees and capital  requirements,  changes in
prevailing   interest  rates,   credit  risk   management  and   asset/liability
management,  the financial and securities  markets and the  availability  of and
costs associated with sources of liquidity.

Results of Operations  for Three Months Ending  September 30, 2003 and September
30, 2002

General

The Company  earned net income of  $3,241,000,  or $1.03 per share for the three
months ended September 30, 2003, compared to net income of $2,952,000,  or $0.94
per share,  for the three months ended  September 30, 2002, an increase of 9.8%.
The higher net  income is  attributable  to lower  interest  expense  and higher
noninterest income. The Company's  annualized return on average assets was 1.78%
and 1.87%,  respectively,  for the three-month periods ending September 30, 2003
and 2002.  The  Company's  annualized  return on  average  equity was 12.42% and
11.80%,  respectively  for the three month periods ending September 30, 2003 and
2002.

AVERAGE BALANCE SHEETS AND INTEREST RATES

The  following  table sets forth certain  information  relating to the Company's
average balance sheets and reflects the average yield on assets and average cost
of  liabilities  for the  three  month  periods  ended  September  30,  2003 and
September 30, 2002, respectively.

Net Interest Income

For the three months ended September 30, 2003, the Company's net interest margin
was 4.10%  compared to 4.64% for the three months ended  September 30, 2002. Net
interest income, prior to the adjustment for tax-exempt income, for the quarters
ended   September  30,  2003  and  2002  totaled   $6,351,000  and   $6,242,000,
respectively.  Net interest  income  increased 1.8% compared to the  three-month
period  one-year ago despite the lower net interest  margin.  A higher volume of
interest-earning  assets,  primarily associated with the growth of United Bank &
Trust (United  Bank),  Marshalltown,  Iowa,  combined with a lower cost of funds
served to offset the loss of income  resulting  from assets  repricing  to lower
market rates.

For the three  months  ended  September  30,  2003,  interest  income  decreased
$234,000 or 2.6% when  compared to the same period in 2002.  This  decrease  was
primarily  attributable to  significantly  lower yields on earning assets as the
result  of  a  decline  in  market  interest  rates.  The  competitive   banking
environment in central Iowa continues to place significant  downward pressure on
loan yields.

Interest expense decreased $343,000 or 12.2% for the quarter ended September 30,
2003 when compared to the same period in 2002.  Lower interest rates on deposits
and other  borrowings  resulted in decreased  interest  expense as the Company's
cost of funds declined with market interest rates in spite of an increase in the
average volume of interest-bearing liabilities.

Provision for Loan Losses

The  Company  provided  $87,000  for loan  losses  for the  three  months  ended
September  30,  2003  compared  to  $81,000  during the same  period  last year.
Provision  expense for the second quarter of 2003 was higher than the prior year
period primarily as the result of increased amounts  associated with loan growth
at United Bank.

Noninterest Income and Expense

Noninterest  income  increased  $618,000,  or 47.1%  during  the  quarter  ended
September  30, 2003  compared to the same period in 2002.  The  increase  can be
attributed  to  increased  fee  income on the sale of  residential  loans in the
secondary  mortgage  market and gains on the sale of securities in the Company's
equity portfolio.

Noninterest  expense  increased  $295,000 or 8.8% for the second quarter of 2003
compared to the same period in 2002.  Noninterest  expense items that  increased
include salary and benefits, occupancy, data processing and equipment costs. The
higher costs in 2003 are in part  attributable to higher overhead  expenses with
operating United Bank. The efficiency ratio for the three months ended September
30, 2003 and 2002 was 44.0% and 44.4, respectively.

Income Taxes

The provision  for income taxes for  September 30, 2003 and 2002 was  $1,309,000
and $1,172,000,  respectively.  This amount  represents an effective tax rate of
28.8% for the third quarter of 2003,  compared to 28.4% for the third quarter of
2002. The Company's  marginal  federal tax rate is currently 35%. The difference
between the Company's  effective  and marginal tax rate is primarily  related to
investments made in tax exempt securities.

Results of Operations  for Nine Months  Ending  September 30, 2003 and September
30, 2002

General

The  Company  earned  net income of  $8,760,000  or $2.80 per share for the nine
months ended September 30, 2003, compared to net income of $8,634,000,  or $2.76
per share,  for the nine months ended  September  30, 2002, an increase of 1.5%.
Significantly  higher  noninterest  income offset higher  provision  expense and
noninterest expense. The Company's annualized return on average assets was 1.63%
and 1.83%, respectively for the nine-month periods ending September 30, 2003 and
2002. The Company's  annualized  return on average equity was 11.28% and 11.83%,
respectively for the nine month periods ending September 30, 2003 and 2002.

Net Interest Income

For the nine months ended  September 30, 2003, the Company's net interest margin
was 4.02%  compared to 4.54% for the nine months ended  September 30, 2002.  Net
interest  income,  prior to the adjustment for tax-exempt  income,  for the nine
months ended September 30, 2003 and 2002 totaled  $18,528,000  and  $18,415,000,
respectively. Net interest income was slightly higher compared to the nine-month
period  one-year ago despite the lower net interest  margin.  A higher volume of
interest-earning  assets,  primarily  associated with the growth of United Bank,
combined  with a lower  cost of  funds  served  to  offset  the  loss of  income
resulting from assets repricing to lower market rates.

For the nine months ended September 30, 2003, interest income decreased $910,000
or 3.3% when  compared to the same period in 2002.  This  decrease was primarily
attributable to significantly  lower yields on earning assets as the result of a
decline in market interest rates. The competitive banking environment in central
Iowa continues to place significant downward pressure on loan yields.

Interest  expense  decreased  $1,022,000  or  11.5%  for the nine  months  ended
September  30, 2003 when  compared to the same  period in 2002.  Lower  interest
rates on deposits and other borrowings resulted in decreased interest expense as
the Company's cost of funds declined with market interest rates.

Provision for Loan Losses

The  Company  provided  $513,000  for  loan  losses  for the nine  months  ended
September  30,  2003  compared  to  $296,000  during the same  period last year.
Provision expense for the nine month period ending September 30, 2003 was higher
than the  prior  year  period  primarily  as the  result of  increased  specific
allowance for impaired loans and  establishing  the allowance for loan losses at
United Bank.

Noninterest Income and Expense

Noninterest income increased  $1,535,000,  or 43.8% during the nine months ended
September  30, 2003  compared to the same period in 2002.  The  increase  can be
attributed  to  increased  fee  income on the sale of  residential  loans in the
secondary  market,  gains  on the sale of  securities  in the  Company's  equity
portfolio, and higher trust department income.

Noninterest  expense increased  $1,331,000 or 13.9% for the first nine months of
2003 compared to the same period in 2002.  Noninterest  expense increased as the
result of the opening of United Bank.  United Bank opened in June of 2002 so the
nine month period  ending  September  30, 2003  includes  nearly two  additional
quarters of  noninterest  expense versus the same nine month period in 2002. The
efficiency ratio for the nine months ended September 30, 2003 and 2002 was 46.4%
and 43.8, respectively.

Income Taxes

The provision for income taxes for the nine months ending September 30, 2003 and
2002 was  $3,369,000 and  $3,396,000,  respectively.  This amount  represents an
effective tax rate of 27.8% for the first nine months of 2003, compared to 28.2%
for the  same  period  in  2002.  The  Company's  marginal  federal  tax rate is
currently 35%. The difference  between the Company's  effective and marginal tax
rate is primarily related to investments made in tax exempt securities.

Financial Condition

Assets

As of September 30, 2003, total assets were $738,764,000, a $61,536,000 increase
in comparison to December 31, 2002 totals.  Deposit  growth  primarily at United
Bank as well as the other  Company's  subsidiary  banks  and a higher  volume of
federal funds sold resulting from temporary  large public fund deposit  balances
associated  with the  collection of property  taxes allowed for the  significant
increase in earning assets.

Investment Portfolio

The increase in the volume of investment securities to $300,767,000 on September
30, 2003 from  $244,575,000  on December 31, 2002  resulted from the purchase of
U.S. government agencies and municipal bonds.

Loan Portfolio

Net  loans as of  September  30,  2003  totaled  $345,003,000,  an  increase  of
$12,697,000 from the outstanding  balances as of December 31, 2002. The increase
relates to loans generated by United Bank.

Impaired  loans  totaled  $1,820,000  as  of  September  30,  2003  compared  to
$2,409,000 as of December 31, 2002. A loan is considered impaired when, based on
current  information and events,  it is probable that the Company will be unable
to collect the scheduled payments of principal or interest when due according to
the  contractual  terms of the loan  agreement.  Impaired  loans  include  loans
accounted for on a non-accrual  basis;  accruing  loans which are  contractually
past  due 90  days  or  more  as to  principal  or  interest  payments;  and any
restructured  loans.  As  of  September  30,  2003,  non-accrual  loans  totaled
$1,607,000,  past due loans still  accruing  totaled  $213,000 and there were no
restructured loans outstanding. Other real estate owned as of September 30, 2003
and December 31, 2002 totaled $124,000 and $295,000, respectively.

Net charge offs were  $321,000 for the nine months ended  September  30, 2003 as
compared to net  charge-offs  $177,000 for the nine months ended  September  30,
2002.  Losses related  primarily to previously  identified  impaired  commercial
loans for both periods.  The resulting  allowance for loan losses was $5,950,000
as of September 30, 2003  compared to  $5,758,000  as of December 31, 2002.  The
allowance  for loan  losses  as a  percentage  of  outstanding  loans as of both
September 30, 2003 and December 31, 2002 was 1.70%.

The allowance for loan losses is  management's  best estimate of probable losses
inherent in the loan portfolio as of the balance sheet date.  Factors considered
in establishing an appropriate allowance include: an assessment of the financial
condition of the borrower;  a realistic  determination  of value and adequacy of
underlying  collateral;  the condition of the local economy and the condition of
the specific  industry of the borrower;  an analysis of the levels and trends of
loan categories; and a review of delinquent and classified loans.

Liabilities

Deposits  increased  $51,900,000  from year-end  2002. The increase is primarily
attributable to deposits generated by United Bank.

Other borrowed funds as of September 30, 2003, consisted primarily of securities
sold under agreements to repurchase totaling $22,452,000 compared to total other
borrowing as of December 31, 2002 of $18,326,000.

Liquidity and Capital Resources

The  objective  of  liquidity  management  is  to  ensure  the  availability  of
sufficient  cash flows to meet all  financial  commitments  and to capitalize on
opportunities for profitable business expansion.  The Company's principal source
of funds is deposits including demand, money market, savings and certificates of
deposits. Other sources include principal repayments on loans, proceeds from the
maturity and sale of investment securities, federal funds purchased,  repurchase
agreements,  advances  from the  Federal  Home Loan Bank and funds  provided  by
operations.  Net cash  from  operating  activities  contributed  $9,736,000  and
$8,565,000 to liquidity  for the nine months ended  September 30, 2003 and 2002,
respectively.  Liquid  assets  including  cash on hand,  balances due from other
banks,   federal   funds  sold  and   interest-bearing   deposits  in  financial
institutions  decreased  to  $77,770,000  as of September  30, 2003  compared to
year-end  2002 balance of  $85,189,000.  The  decrease in federal  funds sold is
attributable to the purchase of U.S. government agencies and municipal bonds.

Securities available for sale increased to $300,767,000 as of September 30, 2003
from  $244,575,000  as of  December  31,  2002 and  provide  another  source  of
liquidity for the Company.

To provide additional  external  liquidity,  the Banks have outstanding lines of
credit with the Federal Home Loan Bank of Des Moines,  Iowa of  $30,732,000  and
federal funds borrowing  capacity at correspondent  banks of $46,000,000.  As of
September 30, 2003, the Company had no  outstanding  borrowings of federal funds
purchased  or Federal  Home Loan Bank  advances.  Management  believes  that the
Company's  liquidity  sources will be sufficient to support existing  operations
for the foreseeable future.


                                       14


The  Company's  total  stockholder's  equity  increased  to  $104,836,000  as of
September 30, 2003,  from  $101,523,000  as of December 31, 2002.  Stockholders'
equity as of September 30, 2003 was 14.2% of total assets,  compared to 15.0% at
December 31, 2002.  Total equity  increased due to the retention of earnings and
from  appreciation  in the  Company  and Banks'  stock and bond  portfolios.  No
material  capital  expenditures or material  changes in the capital resource mix
are  anticipated  at this time.  Management  believes  that, as of September 30,
2003, the Company and its Banks meet the capital  requirements to which they are
subject.  As of that date, all the Company's Banks were "well capitalized" under
regulatory prompt corrective action provisions.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company's  market risk is comprised  primarily of interest rate risk arising
from its core banking  activities of lending and deposit  taking.  Interest rate
risk  results  from the changes in market  interest  rates  which may  adversely
affect the Company's net interest income.  Management  continually  develops and
applies  strategies to mitigate this risk.  Management does not believe that the
Company's  primary  market risk exposure and how it has been managed  to-date in
2003 changed significantly when compared to 2002.

Item 4. Disclosure Controls and Procedures

As of the end of the period  covered by this  report,  the Company  conducted an
evaluation,  under the supervision and with the  participation  of the principal
executive officer and principal financial officer,  of the Company's  disclosure
controls and procedures (as defined in Rules  13a-15(e) and 15d-15(e)  under the
Securities Exchange Act of 1934 (the "Exchange Act")). Based on this evaluation,
the principal  executive officer and principal  financial officer concluded that
the Company's  disclosure  controls and  procedures are effective to ensure that
information  required to be disclosed by the Company in reports that it files or
submits under the Exchange Act is recorded,  processed,  summarized and reported
within the time periods  specified in Securities and Exchange  Commission  rules
and forms.  There was no change in the Company's internal control over financial
reporting  during the Company's most recently  completed fiscal quarter that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
