              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - BASIS OF PRESENTATION

The consolidated financial statements of Sistersville Bancorp, Inc.(the
"Company"),include its wholly-owned subsidiary, First Federal Savings Bank (the
"Bank"). All significant intercompany balances and transactions have been
eliminated.

The accompanying unaudited consolidated financial statements have been prepared
in accordance with the instructions to Form 10-QSB and, therefore, do not
necessarily include all information that would be included in audited financial
statements. The information furnished reflects all adjustments which are, in the
opinion of management, necessary for a fair statement of the results of
operations. All such adjustments are of a normal recurring nature. The results
of operations for the interim periods are not necessarily indicative of the
results to be expected for the fiscal year ended March 31, 2001.

These statements should be read in conjunction with the consolidated statements
as of and for the fiscal year ended March 31, 2000, and related notes which are
included in the Company's Annual Report on Form 10-KSB (file no. 0-2535).

NOTE 2 - RECENT ACCOUNTING STANDARDS

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 provides accounting and
reporting standards for derivatives instruments, including certain derivative
instruments embedded in other contracts, by requiring the recognition of those
items as assets or liabilities in the statement of financial position, recorded
at fair value. SFAS No. 133 precludes a held-to-maturity security from being
designated as a hedge item. However, at the date of initial application of SFAS
No. 133, an entity is permitted to transfer any held-to- maturity security into
the available-for-sale or trading categories. The unrealized holding gain or
loss on such transferred securities shall be reported consistent with the
requirements of SFAS No. 115, "Accounting for Certain Investment in Debt and
Equity Securities." Such transfers do not raise an issue regarding an entity's
intent to hold other debt securities to maturity in the future. The FASB has
also issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities-Deferral of the Effective date of FASB Statement No. 133." SFAS No.
137 defers the effective date of SFAS No. 133 to be effective for all fiscal
quarters beginning after June 15, 2000. Earlier adoption is permitted for any
fiscal quarter that begins after the issue date of SFAS No. 133. The adoption of
SFAS No. 133 did not have a material impact on the Company.

The FASB issued SFAS No. 138, "Accounting for Certain Derivative Instruments and
Certain Hedging Activities." SFAS No. 138 addresses a limited number of issues
causing implementation difficulties for numerous entities that have adopted SFAS
No. 133 and amends the accounting and reporting standards for SFAS No. 133 for
certain derivative instruments and certain hedging activities as indicated in
the statement. The effective date of this statement is concurrent with the
effective date of SFAS. No. 133 (deferred by SFAS No. 137), which is for all
fiscal quarters beginning after June 15, 2000. The adoption of SFAS No. 138 did
not have a material impact on the Company.

FASB recently issued SFAS No. 140, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities." SFAS No. 140 replaces SFAS
No. 125 and revises the standards for accounting for securitizations and other
transfers of financial assets and collateral and requires certain disclosures,
but it carries over most of SFAS 125's provisions without reconsideration. Under
SFAS No. 140, after a transfer of financial assets, an entity must recognize the
financial and servicing assets it controls and the liabilities it has incurred,
and derecognize financial assets when control has been surrendered, and
derecognize liabilities when extinguished. A transfer of financial assets in
which the transferor surrenders control over those assets is accounted for as a
sale to the extent that consideration other than beneficial interests in the
transferred assets is received in exchanged. This Statement is generally
effective for activity occurring after March 31, 2001. Earlier or retroactive
application of this Statement is not permitted. Management believes that the
adoption of SFAS No. 140 will not have a material impact on the Company.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

Comparison of Financial Condition at December 31, 2000 and March 31, 2000
-------------------------------------------------------------------------

Total assets increased by $1,928,000 to $33,690,000 at December 31, 2000, from
$31,762,000 at March 31, 2000. Cash and cash equivalents increased by $215,000
to $604,000 at December 31, 2000, from $389,000 at March 31, 2000. The increase
is a result of an increase in customer deposits, cash provided by operating
activities, and principal collected on mortgage-backed securities offset by the
net increase in loans, purchase of office properties and equipment, decrease in
the Federal Home Loan Bank advance, purchase of shares for treasury, and
dividends paid to stockholders. Investment securities increased $515,000 to
$4,868,000 at December 31, 2000, from $4,353,000 at March 31, 2000. The increase
was a result of the purchase of additional Federal Home Loan Bank (FHLB) stock
of $11,000 and an increase in the fair value of available-for-sale securities of
$623,000 offset by principal collected on mortgage-backed securities of
$118,000. Net loans receivable increased by $855,000 to $26,244,000 at December
31, 2000, from $25,389,000 at March 31, 2000. The increase in loans was
attributable to an increase in one- to-four family residential mortgage loans.
Such increases primarily reflect the economic health of the Bank's market area
and competitive pricing of the Bank's loan products. Office property and
equipment increased by $308,000 to $1,677,000 at December 31, 2000 from
$1,369,000 at March 31, 2000, which was a direct result of construction costs of
the new branch office, located in Parkersburg, West Virginia.

Total liabilities increased by $2,142,000 to $24,481,000 at December 31, 2000,
from $22,339,000 at March 31, 2000. This increase was mostly attributable to an
increase in deposits of $2,163,000, to $23,217,000 at December 31, 2000, from
$21,054,000 at March 31, 2000, which was a direct result of deposit growth
attributed to the new branch office. Deferred income taxes increased $217,000 to
$417,000 at December 31, 2000 from $200,000 at March 31, 2000 as a result of the
increase in the fair value of available-for-sale securities. The Federal Home
Loan Bank advance decreased by $250,000, from $900,000 at March 31, 2000, to
$650,000 at December 31, 2000, as funds provided by the increase in deposit
accounts were used to reduce the advance.

Stockholders' equity decreased by $215,000, to $9,209,000 at December 31, 2000,
from $9,424,000 at March 31, 2000. The decrease was attributable to $667,000 in
shares purchased for treasury and $184,000 in dividends paid to stockholders,
offset by net income of $175,000, an increase in unrealized gains on
available-for-sale securities of $401,000 and amortization of RSP and ESOP
shares of $60,000. The increase in treasury stock was a result of a ten percent
(10%) stock repurchase completed by the Company in December.

Comparison of the Results of Operations for the Three Months ended
December 31, 2000 and 1999
------------------------------------------------------------------

Net income decreased by $1,000, to net income of $65,000 for the three month
period ended December 31, 2000, compared to net income of $66,000 for the three
months ended December 31, 1999.

Interest and dividend income increased by $20,000, from $569,000 for the three
months ended December 31, 1999, to $589,000 for the same period in 2000. The
increase is attributed to an increase in interest on loans of $26,000, partially
offset by a decrease in interest and dividends on investments of $6,000. The
increase in interest on loans is attributed to the average balance on loans
increasing by $846,000, to $26,135,000 for the period ended December 31, 2000,
compared to $25,289,000 for the period ended December 31, 1999. The decrease in
interest and dividends on investments is a result of a lower average balance in
funds invested for the December 31, 2000 period compared to the same period in
1999.

Interest expense increased by $31,000, to $265,000 for the three month period
ended December 31, 2000, compared to $234,000 for the same three month period in
1999. Interest expense on deposits increased by $41,000, to $261,000 for the
three month period ended December 31, 2000, compared to $220,000, for the same
period in 1999. The increase in interest on deposits is attributed to an
increase in average deposits of $1,926,000, to $23,071,000 for the three month
period ended December 31, 2000, compared to $21,145,000 for the three month
period ended December 31, 1999, and due to an increase of 0.37% in the average
yield on deposits during the period ended December 31, 2000 compared to the
corresponding period in 1999. Interest expense on advances from the Federal Home
Loan Bank decreased by $10,000 due to a reduction in the average balance of the
advance during the December 31, 2000 period.

Management regularly performs an analysis to identify the inherent risk of loss
in its loan portfolio. This analysis included evaluation of concentrations of
credit, past loss experience, current economic conditions, amount and
composition of the loan portfolio (including loans specifically monitored by
management), estimated fair value of underlying collateral, loan commitments
outstanding, delinquencies, and other factors. Based on this analysis,
management established an allowance for loan losses. The allowance for loan
losses is adjusted periodically by a provision for loan losses which is charged
to operations based on management's evaluation of the losses that may be
incurred in the Bank's portfolio. The provision for loan losses decreased by
$650, to $300, for the three months ended December 31, 2000, compared to $950
for the same period in 1999.



                                      -10-
<PAGE>   11


The Bank will continue to monitor its allowance for loan losses and make future
additions to the allowance through the provision for loan losses as economic
conditions dictate. Although the Bank maintains its allowance for loan losses at
a level that it considers to be adequate to provide for the inherent risk of
loss it its loan portfolio, there can be no assurance that future losses will
not exceed estimated amounts or that additional provisions for loan losses will
not be required in future periods. In addition, the Bank's determination as to
the amount of its allowance for loan losses is subject to review by its primary
federal regulator, the Office of Thrift Supervision (OTS), as part of its
examination process, which may result in the establishment of an additional
allowance based on the judgment of the OTS after a review of the information
available at the time of the OTS examination.

Non-interest income increased by $1,000, to $10,000 for the three month period
ended December 31, 2000, compared to $9,000, for the same period in 1999. The
increase is attributed to the increase in service charge income.

Non-interest expense increased by $11,000, to $250,000 for the three month
period ended December 31, 2000, compared to $239,000 for the three month period
ended December 31, 1999. The increase is a result of increased salaries and
benefits and occupancy expenses associated with the new branch offset by the
decrease in Restricted Stock Plan ("RSP") compensation expense. RSP compensation
expense decreased as a result of an agreement with employees to defer the
earning and recognition of their previously awarded shares.

Income tax expense decreased by $20,000, from $39,000 for the three month period
ended December 31, 1999, to $19,000 for the three month period ended December
31, 2000. The decrease is attributed to lower pre-tax income for the three month
period ended December 31, 2000 compared to the same period in 1999.

Comparison of the Results of Operations for the Nine Months
ended December 31, 2000 and 1999
-----------------------------------------------------------

Net income decreased by $28,000, to net income of $175,000 for the nine month
period ended December 31, 2000, compared to net income of $203,000 for the nine
months ended December 31, 1999.

Interest and dividend income increased by $11,000, from $1,720,000 for the nine
months ended December 31, 1999, to $1,731,000 for the same period in 2000. The
increase is attributed to an increase in interest on loans of $60,000, to
$1,542,000 for the nine months ended December 31, 2000, compared to $1,482,000,
for the nine months ended December 31, 1999. The increase in interest on loans
is attributed to the average balance on loans increasing by $1,048,000, to
$25,930,000 for the period ended December 31, 2000, compared to an average
balance on loans of $24,882,000 for the period ended December 31, 1999. Interest
on investments decreased $49,000, from $237,000 for the nine month period ended
December 31, 1999, to $188,000 for the same period in 2000. The decrease in
interest on investments was due to the decrease in average investments of
$1,502,000, from $6,205,000 for the nine month period ended December 31, 1999,
to $4,703,000 for the nine month period ended December 31, 2000.

Interest expense increased by $53,000, to $758,000 for the nine month period
ended December 31, 2000, compared to $705,000 for the same period in 1999.
Interest expense on deposits increased by $50,000, to $716,000 for the nine
month period ended December 31, 2000, compared to $666,000 for the same period
in 1999. The increase in interest expense on deposits is attributed to the
increase in average deposits of $770,000, to $21,963,000 for the nine month
period ended December 31, 2000, compared to $21,193,000 for the nine month
period ended December 31, 1999, and due to an increase of 0.16% in the average
yield on deposits during the period ended December 31, 2000 compared to the
corresponding period in 1999. Interest expense on Federal Home Loan Bank
advances increased $3,000 for the period ended December 31, 2000 compared to the
corresponding period in 1999.

Management regularly performs an analysis to identify the inherent risk of loss
in its loan portfolio. This analysis included evaluation of concentrations of
credit, past loss experience, current economic conditions, amount and
composition of the loan portfolio (including loans specifically monitored by
management), estimated fair value of underlying collateral, loan commitments
outstanding, delinquencies, and other factors. Based on this analysis,
management established an allowance for loan losses. The allowance for loan
losses is adjusted periodically by a provision for loan losses, which is charged
to operations based on management's evaluation of the losses that may be
incurred in the Bank's portfolio. The provision for loan losses decreased by
$2,000, to $1,000, for the nine months ended December 31, 2000, compared to
$3,000 for the same period in 1999.

The Bank will continue to monitor its allowance for loan losses and make future
additions to the allowance through the provision for loan losses as economic
conditions dictate. Although the Bank maintains its allowance for loan losses at
a level that it considers to be adequate to provide for the inherent risk of
loss it its loan portfolio, there can be no assurance that future losses will

federal regulator, the Office of Thrift Supervision (OTS), as part of its
examination process, which may result in the establishment of an additional
allowance based on the judgment of the OTS after a review of the information
available at the time of the OTS examination.

Non-interest income increased by $6,000, to $33,000 for the nine month period
ended December 31, 2000, compared to $27,000, for the same period in 1999. The
increase is attributed to an increase in service charge income.

Non-interest expense increased by $33,000, to $766,000 for the nine month period
ended December 31, 2000, compared to $733,000 for the nine month period ended
December 31, 1999. The increase is attributed to an increase in salaries and
benefits of $27,000, to $434,000 for the nine month period ended December 31,
2000, from $407,000 for the same nine month period in 1999, which is the result
of the addition of personnel for the new Parkersburg branch office. This was
partially offset by a loss on the sale of securities of $23,000 during the nine
month period ended December 31, 1999, which did not occur during the nine month
period ended December 31, 2000. The remaining increase of $29,000 for the nine
month period ended December 31, 2000, compared to the same nine month period in
1999, is directly attributed to the increases in occupancy, advertising, and
equipment expense related to the opening of the new branch in Parkersburg, West
Virginia.

Income tax expense decreased by $39,000, from $103,000 for the nine month period
ended December 31, 1999, to $64,000 for the nine month period ended December 31,
2000, attributed to a decrease in pre-tax income.


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

The Bank's primary sources of funds are deposits, amortization and prepayment of
loans, maturities of investment securities, and funds provided from operations.
While scheduled loan repayments are a relatively predictable source of funds,
deposit flows and loan prepayments are greatly influenced by general interest
rates, economic conditions, and competition. In addition, the Bank invests
excess funds in overnight deposits which provide liquidity to meet lending
requirements.

The Bank has other sources of liquidity if a need for additional funds arises.
Additional sources of liquidity include funds available from the Federal Home
Loan Bank ("FHLB") of Pittsburgh amounting to $21.2 million. As of December 31,
2000, the Bank had $650,000 in outstanding advances from the FHLB.

As of December 31, 2000, the Bank had $1,120,000 in outstanding mortgage and
construction loan commitments. Management believes that it has adequate sources
to meet the actual funding requirements.

Management monitors the Bank's tangible, core, and risk-based capital ratios in
order to assess compliance with OTS regulations. At December 31, 2000, the Bank
exceeded the minimum capital ratios requirements imposed by the OTS.

At December 31, 2000, the Bank's capital ratios were as follows:

RISK ELEMENTS

The table below shows information concerning non-performing assets including
non-accrual loans, renegotiated loans, loans 90 days or more past due, other
real estate loans, and repossessed assets. A loan is classified as non- accrual
when, in the opinion of management, there are serious doubts about
collectibility of interest and principal. At the time the accrual of interest is
discontinued, future income is recognized only when cash is received.
Renegotiated loans are those loans which terms have been renegotiated to provide
a reduction or deferral of principal or interest as a result of the
deterioration of the borrower's ability to pay.

Management monitors impaired loans on a continual basis. As of December 31,
2000, the Company had no impaired loans.

During the nine months ended December 31, 2000, loans increased $854,000 and
non-performing loans increased $47,000 while the allowance for loan losses
increased $1,000 for the same period. The percentage of allowance for loan
losses to loans outstanding remained at 0.7% during this time period. The
collateral requirements on such loans reduce the risk of potential losses to an
acceptable level in management's opinion.
