                      (In thousands, except for share data)

(1)      General

         The consolidated financial statements include the accounts of Pinnacle
Bankshares Corporation (the "Company") and its wholly-owned subsidiary, The
First National Bank of Altavista (the "Bank"). All material intercompany
accounts and transactions have been eliminated. The financial statements conform
to generally accepted accounting principles and to general banking industry
practices. In the opinion of the company's management, the accompanying
unaudited consolidated financial statements contain all adjustments of a normal
recurring nature, necessary to present fairly the financial position as of
September 30, 1997, the results of operations for the three-month and nine-month
periods ended September 30, 1997 and 1996, and cash flows for the nine-month
periods ended September 30, 1997 and 1996.

         These consolidated financial statements should be read in conjunction
with the consolidated financial statements and notes thereto included in The
First National Bank of Altavista's Annual Report for the year ended December 31,
1996.

         The results of operations for the interim periods are not necessarily
indicative of the results to be expected for the full year ending December 31,
1997.

(2)      Cash and Cash Equivalents

         For purposes of reporting cash flows, cash and cash equivalents include
cash on hand, amounts due from banks (with original maturities of three months
or less), and federal funds sold.

(3)      Securities

         The amortized costs, gross unrealized gains, gross unrealized losses,
and fair values for securities at September 30, 1997, are shown in the table
below. As of September 30, 1997, securities with amortized costs of $3,950 and

ITEM 2.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                  CONDITION AND RESULTS OF OPERATIONS (Amounts in 000's)

         The following discussion supplements and provides information about the
major components of the results of operations and financial condition, liquidity
and capital resources of Pinnacle Bankshares Corporation (the "Company"). The
discussion below reflects the Consolidated Financial Statements of the Company
and its subsidiary. This discussion and analysis should be read in conjunction
with the Consolidated Financial Statements, and supplemental financial data.

OVERVIEW

         Total assets at September 30, 1997 were $129,058, up 3.29% from
$124,951 at December 31, 1996. The principal components of the Company's assets
at the end of the period were $33,681 in securities and $86,481 in net loans.
During the nine month period, gross loans increased 8.25% or $6,680. The
Company's lending activities are a principal source of income.

         The Company's premises and equipment grew 89.12%, basically due to
contracts-in-progress related to construction of an addition to the main office
facility. In addition, on August, 14, 1997, the Bank formed a subsidiary, FNB
Property Corp., and through this subsidiary has purchased property in Campbell
County for future expansion.

         Total liabilities at September 30, 1997 were $115,368, up from $112,294
at December 31, 1996, with the increase reflective of a rise in total deposits
of $2,807 or 2.52%. Non-interest bearing demand deposits decreased $896 or 9.11%
and represented 7.84% of total deposits. The Company's deposits are provided by
individuals and businesses located within the communities served.

         Total shareholders' equity at September 30, 1997 was $13,690. At
December 31, 1996, total shareholders' equity was $12,657.

         The Company had net income of $1,292 for the nine months ended
September 30, 1997, compared with net income of $1,169 for the comparable period
in 1996, an increase of 10.52%. The results of operations for the nine month
periods ended September 30, 1997 and 1996 are not necessarily indicative of the
results to be expected for the full year.

         Profitability as measured by the Company's return on average assets
(ROA) was 1.36% for the third quarter of 1997, up from 1.29% for the same period
of 1996. Another key indicator of performance, the return on average equity
(ROE) for September 30, 1997 was 13.33%, compared to 13.31% for September 30,
1996.

NET INTEREST INCOME

         Net interest income represents the principal source of earnings for the
Company. Net interest income equals the amount by which interest income exceeds
interest expense. Changes in the volume and mix of earning assets and
interest-bearing liabilities, as well as their respective yields and rates, have
a significant impact on the level of net interest income. Changes in the
interest rate environment and the Company's cost of funds also affected net
interest income.

          The net interest margin increased from 4.31% for the nine months
ending September 30, 1996, to 4.54% for the nine months ending September 30,
1997. Net interest income was $3,898 for the nine months ended September 30,
1997 and is attributable to interest income from loans and securities exceeding
the cost associated with interest paid on deposits. The Company benefitted from
lower interest expense due to certain deposits repricing at lower rates.

         Net interest income for the three months ended September 30, 1997 was
$1,329, up $125, or 10.38% from $1,204 for the same three months of 1996.

NON-INTEREST INCOME

         The Company's principal sources of non-interest income are service
charges and fees on deposits accounts, particularly transaction accounts, and
fees from loans. Non-interest income increased $38 or 14.07% for the nine month
period ending September 30, 1997 over the same period of 1996. Non-interest
income increased $11, or 13.10% when comparing the three months ended September
30, 1997 to the same period of 1996. The majority of this increase is attributed
to income generated from loan fees and commissions on credit insurance.

NON-INTEREST EXPENSE

         Non-interest expense increased $67 or 3.24%, for the nine month period
ending September 30, 1997 over the same period of 1996. The increase in
non-interest expense when comparing the two periods is attributed to overall
growth of the Company and expenses connected with repossessed vehicles. A
decrease of 4.94% is reflected when comparing the three month period ended
September 30, 1997 to the same period of 1996. This decrease is due to a
decrease in FDIC expense. In 1996, the Bank was required to make a one-time SAIF
assessment to the FDIC in the amount of $89.

ALLOWANCE AND PROVISION FOR LOAN LOSSES

         A provision for loan losses of $285 was made for the first nine months
of 1997 in recognition of management's estimate of risks

                                       10

inherent with lending activities. Among other factors, management considers the
Company's historical loss experience, the size and composition of the loan
portfolio, the value and adequacy of collateral and guarantors, non-performing
credits, and current and anticipated economic conditions. There are additional
risks of future loan losses which cannot be precisely quantified or attributed
to particular loans or classes of loans. Since those risks include general
economic trends as well as conditions affecting individual borrowers, the
allowance for loan losses is an estimate. The allowance is also subject to
regulatory examinations and determination as to adequacy, which may take into
account such factors as the methodology used to calculate the allowance. The
allowance for loan losses was $772 as of September 30, 1997, and represents
approximately .88% of gross loans outstanding. Management believes the allowance
was adequate as of September 30, 1997. Management evaluates the reasonableness
of the allowance for loan losses on a quarterly basis and adjusts the provision
as deemed necessary.

NON-PERFORMING ASSETS

         Total nonperforming assets, which consist of nonaccrual loans, were $80
at September 30, 1997 and December 31, 1996. Management believes losses, if any,
will be minimal. Loans are generally placed in nonaccrual status when the
collection of principal and interest is 90 days or more past due, unless the
obligation is both well-secured and in the process of collection.

LIQUIDITY

         Liquidity measures the ability of the Company to meet its maturing
obligations and existing commitments, to withstand fluctuations in deposit
levels, to fund its operations, and to provide for customers' credit needs.
Liquidity represents an institution's ability to meet present and future
financial obligations through either the sale or maturity of existing assets or
the acquisition of additional funds from alternative funding sources. Liquidity
is provided by cash and due from banks, federal funds sold, investments
available for sale, interest-earning deposits in other financial institutions
and loan repayments. As a result of the Company's management of liquid assets
and the ability to generate liquidity through alternative funding sources,
management believes that the Company maintains overall liquidity which is
sufficient to satisfy its depositors' requirements and to meet customers' credit
needs. At September 30, 1997, cash, securities classified as available for sale
and federal funds sold were 21.60% of total earning assets compared to 24.71% at
December 31, 1996. Liquidity is also provided by managing the investment
maturities. Additional sources of liquidity available to the Company include its
capacity to borrow additional funds through correspondent banks.

CAPITAL

         The Company's financial position at September 30, 1997 reflects
liquidity and capital levels currently adequate to fund anticipated future
business expansion. Capital ratios are well in excess of required regulatory
minimums for a well-capitalized institution. The assessment of capital adequacy
depends on a number of factors such as asset quality, liquidity, earnings
performance, and changing competitive conditions and economic forces. The
adequacy of the Company's capital is reviewed by management on an ongoing basis.
Management seeks to maintain a capital structure that will assure an adequate
level of capital to support anticipated asset growth and to absorb potential
losses.

         Shareholders' equity reached $13,690 at the end of the third quarter of
1997 compared to $12,657 at December 31, 1996. The leverage ratio consists of
Tier I capital divided by quarterly average assets. At September 30, 1997, the
Company's leverage ratio was 10.42% compared to 10.14% at December 31, 1996.
Each of these exceeds the required minimum leverage ratio of 3%.

EFFECTS OF INFLATION

         The effect of changing prices on financial institutions is typically
different from other industries as the Company's assets and liabilities are
monetary in nature. Interest rates are significantly impacted by inflation, but
neither the timing nor the magnitude of the changes are directly related to
price level indices. Impacts of inflation on interest rates, loan demand, and
deposits are reflected in the financial statements.
