NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2000

(1)  In the opinion of management, the interim financial statements reflect all
     adjustments which are of a normal recurring nature necessary to a fair
     statement of the results for the interim periods presented.  The December
     31, 1999 data in the Consolidated Statements of Condition is derived from
     the audited consolidated financial statements included in the Company's
     1999 Annual Report to Shareholders.  The accompanying unaudited interim
     consolidated financial statements and related notes should be read in
     conjunction with the audited consolidated financial statements and related
     notes included in the Company's 1999 Annual Report to Shareholders.
(2)  Basic earnings per share are computed based on the weighted average shares
     outstanding.  Diluted earnings per share are computed based on the weighted
     average shares outstanding adjusted for the dilutive effect of the assumed
     exercise of stock options during the period.

 The following is a reconciliation of basic earnings per share to diluted
  earnings per share for the quarters ended March 31, 2000 and 1999.

(3)  In 1998, the Company formed a wholly owned subsidiary business trust, BSB
     Capital Trust I, L.L.C. (the "Trust"), for the purpose of issuing preferred
     securities. The Trust issued at par $30.0 million of 8.125% preferred
     securities. The Preferred securities are non-voting, mandatorily redeemable
     in 2028, and guaranteed by the Company. The Company's guarantee, together
     with its other obligations under the relevant agreements, constitute a
     full, irrevocable, and unconditional guarantee by the Company of the
     securities issued by the Trust. The entire net proceeds to the Trust from
     the offering were invested in junior subordinated obligations of the
     Company, which are the sole assets of the Trust.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

General
-------

  BSB Bancorp, Inc., holding company for BSB Bank & Trust Company, earned net
income for the quarter ended March 31, 2000 of $5.7 million, or $0.56 per
diluted share, compared to $5.5 million or $0.54 per diluted share for the same
period of 1999.

  On April 20, 2000, NBT Bancorp Inc. (NBT) and BSB Bancorp, Inc. (BSB)
announced the signing of a definitive agreement to merge. This strategic
alliance is expected to create a bank holding company with assets of $4.7
billion and proforma market capitalization of approximately $539 million. The
holding company will adopt a new name before the merger occurs. Under the terms
of the agreement, BSB stockholders will receive two shares of NBT common stock
for each share of BSB held. The merger, which has been unanimously approved by
the boards of directors of NBT and BSB, is subject to standard regulatory and
shareholder approvals. A copy of the definitive documents related to the merger
were filed under cover of Form 8-K on April 21,2000.

  On April 24, 2000, the Board of Directors announced a quarterly cash dividend
of $0.25 per share payable on June 9, 2000 to shareholders of record at the
close of business on May 24, 2000.

Financial Condition
-------------------

  Total assets of the Company decreased from $2,240.9 million at December 31,
1999 to $2,230.9 million at March 31, 2000. During the first three months of
2000, the Company originated $53.1 million of commercial loans, which
contributed to a net increase in the commercial loan portfolio of $32.8 million
from $904.6 million at December 31, 1999 to $937.4 million at March 31, 2000.
The interest rates on these loans are generally tied to the Bank's Prime Rate.
Consumer loans decreased from $468.0 million at December 31, 1999 to $457.7
million at March 31, 2000, and during this period the Company originated $43.6
million in consumer loans.  Real estate loans increased from $349.6 million at
December 31, 1999 to $350.2 million at March 31, 2000. During the above
mentioned period, the Company originated $15.5 million of real estate loans, of
which $4.6 million of residential real estate loans were sold.  Investment
securities decreased from $401.7 million at December 31, 1999 to $395.8 million
at March 31, 2000.

  The average commercial loan at March 31, 2000 was $175,915.  Total loan
commitments to the 10 largest lending relationships ranged from $20.2 million to
$16.1 million at March 31, 2000.  Outstanding loan balances for these 10
relationships ranged from $19.2 million, made up of 17 individual loans, to $4.9
million, made up of 8 individual loans. These loans generally have varied
sources of repayment and collateral. The Bank continually reviews all larger
group credits and often sells participations in these credits to other local
banks to limit exposure.

  Non-performing loans are shown in a table within this report.  See "Non-
Performing Loans and ORE".   Total non-performing loans declined from 0.67% of
total loans at December 31, 1999 to 0.66% of total loans at March 31, 2000.
Total loans, in all types of loan portfolios, which were  30-89 days past due,
rose from $18.5 million at December 31, 1999 to $22.6 million at March 31, 2000.
Respectively, these dollar amounts represent 1.07% and 1.30% of total loans at
those dates, and historically have fluctuated from quarter to quarter.

  The competition for consumer loans has been tremendous, mainly due to the
automobile captive finance companies. Because of this competition, the total
consumer loan portfolio has declined from $468.0 million at December 31, 1999 to
$457.7 million at March 31, 2000. Net charge-offs declined from the first
quarter 1999 amount of $2.3 million to the first quarter 2000 amount of $2.0
million. This, combined with the continued decline in non-performing assets to
$12.2 million at March 31, 2000 from $12.5 million at December 31, 1999, and an
increase in the allowance for loan losses from $29.1 million at December 31,
1999 to $31.7 million at March 31, 2000,  provides, what management feels, is
sufficient reserves to cover potential losses. Gross asset yields through March
31, 2000, were 8.72%, up from 8.29% for the comparable period in 1999.  Net
asset yields, after credit losses, in the first three months of 2000 increased
to 8.34% from 7.83% for the first quarter of 1999.

Item 2 - continued

  Total deposits declined slightly, totaling $1,901.2 million at December 31,
1999 as compared to $1,899.3 million at March 31, 2000.  During the first
quarter 2000, the Bank's money desk funds decreased to $191.3 million at March
31, 2000 from $221.6 million at December 31, 1999, and brokered certificates of
deposits deceased from $231.9 million at December 31, 1999 to $206.4 million at
March 31, 2000.  Offsetting these decreases was an increase in retail
certificates of deposit of $16.6 million and an increase in municipal deposits
of $34.5 million.  The slower growth, or in the case of consumer lending, the
decline, in loan balances has allowed the Bank to focus on using core funding
products. The decrease in the non-core funding products has allowed the Bank to
mitigate the impact that rising interest rates has had on its cost of funds.
Interest credited to depositors and interest paid on borrowings totaled $23.9
million during that three-month period, as compared to $21.4 million for the
first three months of 1999.  The Company's borrowings decreased from $142.0
million at December 31, 1999 to $136.0 million at March 31, 2000.  Borrowings at
March 31, 2000 consisted of $50.0 million of Federal Home Loan Bank advances and
$34.8 million of a Federal Home Loan Bank line of credit.  Of the remaining
$51.2 million, $48.9 million are securities sold under agreement to repurchase.
These borrowings, along with deposits, are used to fund the Company's lending
and investment activities.

  The following factors affected shareholders' equity in the first three months
of 2000.  Earnings and stock options exercised increased shareholders' equity by
$5.7 million and $303,000, respectively.  An increase of $1.0 million in
unrealized losses of available for sale securities and shareholder cash
dividends of $2.6 million reduced shareholders equity for the first three months
of 2000.

Results of Operations
---------------------

  The operating results of the Company depend primarily on its net interest
income, which is the difference between interest income on interest-earning
assets, primarily loans and investments, and interest expense on interest-
bearing liabilities, primarily deposits and borrowings.  The Company's operating
results also are affected by credit losses and provisions for such future
losses, operating expenses, the level of other income, including gains or losses
on sale of loans and securities, and other fees.

Item 2 - continued

  The following tables set forth, for the periods indicated, information
regarding (i) the Company's average balance sheet, (ii) the total dollar amount
of interest income from interest-earning assets and the resulting average
yields, (iii) the total dollar amount of interest expense on interest-bearing
liabilities and the resultant average cost, (iv) net interest income, (v)
interest rate margin and interest rate spread, (vi) net interest-earning assets,
(vii) net yield on interest-earning assets, and (viii) ratio of interest-earning
assets to interest-bearing liabilities.  Average balances are based on daily or
month-end balances.  No tax equivalent adjustments were made.

The following table presents changes in interest income and interest expense
attributable to (i) changes in volume (change in volume multiplied by old rate),
and (ii) changes in rate (change in rate multiplied by old volume).  The net
change attributable to the combined impact of volume and rate has been allocated
proportionately to the change due to volume and the change due to rate.

Interest Income
---------------

  The Company's interest income on interest-earning assets increased from $42.5
million for the three months ended March 31, 1999 to $46.3 million for the three
months ended March 31, 2000, respectively.  This increase in interest income was
the result of increases in the average balance of interest-earning assets from
$2,052.1 million to $2,122.5 million for the three months ended March 31, 1999
and March 31, 2000, respectively.  The increase in average balances was
accompanied by the increase in the average yield on interest-earning assets from
8.29% to 8.72% for the three months ended March 31, 1999 and 2000, respectively.
This reflected steady increases in the Company's Prime Rate totaling 125 basis
points from the 1st quarter of 1999 through the first quarter of 2000.

  The increase in the average balance of the commercial loan portfolio was the
largest contributor to the increase in interest income.  The average balance of
commercial loans increased $77.8 million from the first quarter of 1999 to
$895.5 million for the first quarter of 2000.  The average yield on commercial
loans increased from 8.75% for the first quarter of 1999 to 9.57% for the first
quarter of 2000.  The Prime Rate was 7.75% through the first and second quarter
of 1999, rose to 8.00% in July, 8.25% in August, 8.50% in November 1999, then
continued to increase to 8.75% in February, and to 9.00% in March 2000.

  The average balance of consumer loans increased 10.4% to $459.7 million for
the three-month period ended March 31, 2000 compared to $416.2 million for the
three-month period ended March 31, 1999, with an increase in yield on these
assets from 9.56% for the first quarter of 1999 to 9.71% for the first quarter
of 2000. The Company continues to emphasize origination of indirect and direct
auto loans, which adds to the Company's market base for potential business and
provides some of the highest yielding assets for the Company.  These loans
provided an increase in interest income from $9.9 million compared to the same
period in 1999 to $11.2 million in the first quarter of 2000.

  The average balance of real estate loans decreased $20.5 million to $345.7
million for the quarter ended March 31, 2000 compared to the quarter ended March
31, 1999.  The quarter period reflected an increase in yield from 8.02% to
8.08%, and the reduced average balance resulted in a net decline of $351,000 in
interest income from real estate loans to $7.0 million. The Bank continues to
originate a significant amount of fixed-rate residential mortgage loans and,
after filling the remainder of its loan sale commitments in the first quarter of
2000, will retain the residential mortgages originated in its portfolio.

  The average balance of investment securities decreased from $420.5 million for
the first quarter of 1999 to $419.8 million for the first quarter of 2000.
Yields on investment securities decreased for this same period from 6.51% to
6.36%, as the interest income on investment securities decreased $164,000 for
the comparative quarters.

Interest Expense
----------------

  Total interest expense increased by $2.5 million for the quarter ended March
31, 2000 as compared to the same period in 1999. The average balance of all
interest-bearing liabilities increased from $1,989.3 million for the quarter
ended March 31, 1999 to $2,059.0 million for the quarter ended March 31, 2000,
accompanied by an increase in the average rate paid on all interest-bearing
liabilities from 4.30% to 4.64% during the respective period. The average
balance of deposits increased from $1,726.8 million during the three months
ended March 31, 1999 to $1,887.5 million during the same period in 2000.  This
average balance increase and the increase in the yield of deposits were major
factors contributing to the increase in interest paid on deposits from $17.9
million for the first quarter of 1999 to $21.3 million for the first quarter of
2000.  Another component of the change in interest-bearing liabilities was the
decrease in average balance of borrowings from $232.5 million for the three
months ended March 31, 1999 to $141.6 million for the three months ended March
31, 2000. This decrease in average balance more than offset an increase in the
rate paid on borrowings from 4.89% to 5.55% during the three-month period as
borrowing costs decreased to $2.0 million for the three months ended March 31,
2000. As the balance of deposit accounts tied to moneymarket indices has
increased from $305.1 million at March 31, 1999 to $446.2 million, these
deposits, which reprice in anticipation of the increase in rates, has caused
deposit costs to escalate more rapidly than asset yields.

Provision for Credit Losses
---------------------------

  The provision for credit losses increased from $3.5 million to $4.6 million
for the quarters ended March 31, 1999 and March 31, 2000, respectively. The
allowance for possible credit losses increased to $31.7 million as of March 31,
2000, compared to $29.1 million as of December 31, 1999.  As the nature of the
loan portfolio continues to move toward commercial lending, the Bank continues
to increase the allowance for possible credit losses to reflect the increased
level of risk inherent in this type of lending.  See "Non-performing Loans and
ORE".

Non-interest Income
-------------------

  Non-interest income increased 20.5% from $2.8 million to $3.4 million for the
three months ended March 31, 1999 to March 31, 2000, respectively.  The factors
contributing to the increase comparing first quarter of 1999 to the same quarter
of 2000 were a $213,000 increase in service charges on deposit accounts,
$177,000 in miscellaneous other charges, commissions, and fees, $116,000 in
credit card fees, $80,000 in trust fees, and a $26,000 increase in fees and
commissions on brokerage services.

Gains (Losses) On Sale of Securities
------------------------------------

There were no gains (losses) on sale of securities for the first quarter of
2000.  This compares to losses of $401,000 for the same quarter of 1999.  The
Company's investment portfolio is used to maintain its liquidity position; from
time to time, securities are sold when deemed prudent by management, to adjust
the interest rate sensitivity of the Company's balance sheet.

Gains (Losses) On Sale of Loans
-------------------------------

  In prior years, the practice of the Company had been to sell or securitize
long-term, fixed-rate residential mortgage loans. This provided liquidity to
fund shorter-term, or more rate-sensitive assets, and collateral to provide
borrowing for lending activities.  In 2000, the Company started to retain
originated mortgages for its own portfolio. As a result of this practice, the
Company sold or securitized $4.6 million and $51.8 million for the first quarter
of 2000 and 1999, respectively.  This resulted in gains of $7,000 and $6,000 for
the same two periods, respectively.

Operating Expense
-----------------

  Operating expense increased from $11.2 million for the quarter ended March 31,
1999 to $11.7 million for the quarter ended March 31, 2000.  The main factor
contributing to the increase was the accrual of benefits associated with the
payment of amounts owed under contract with the Company's former President and
CEO, Alex DePersis, in the amount of $855,000 during the first quarter of 2000.
In the first quarter of 1999, acquisition charges of $318,000 were recognized.

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

  The income tax expense was $3.7 million and $3.3 million for the quarters
ended March 31, 2000 and March 31, 1999, respectively.  This increase was mainly
due to increased levels of taxable income.

Non-Performing Loans and ORE
----------------------------

  When a borrower fails to make a scheduled payment on a loan, the Company
attempts to cure the deficiency by contacting the borrower and seeking payment.
Contacts are generally made within five business days after the expiration of
the payment grace period, set forth in the loan contract.  In most cases,
deficiencies are cured promptly.  If a delinquency extends beyond 60 days, the
loan and payment histories are reviewed and legal proceedings may be instituted
to remedy the default. While the Company generally prefers to work with
borrowers to resolve such problems, the Company does initiate foreclosure
proceedings or pursues other legal collection procedures, as necessary, to
minimize any potential loss.  Once the Company takes legal title to the
property, it is classified as ORE on the Statement of Condition.

  Loans are placed on a non-accrual status when, in the judgment of management,
the probability of collection of interest is deemed to be insufficient to
warrant further accrual.  Such loans include potential problem loans where known
information about possible credit problems of borrowers has caused management to
have serious doubts as to the ability of such borrowers to comply with the loan
repayment terms.  When a loan is placed on non-accrual status, previously
accrued but unpaid interest is deducted from interest income.  Other than with
respect to consumer loans, the Company does not accrue interest on loans greater
than 90 days or more past due for the payment of interest unless the value of
the collateral and active collection efforts ensure full recovery.  Consumer
loans are charged-off before they become non-accrual.

  The following table sets forth information regarding non-performing loans
which are 90 days or more overdue and ORE held by the Company at the dates
indicated.

foreclosure, decreased to $12.2 million, or 0.55% of total assets at March 31,
2000, compared to $12.5 million, or 0.56% of total assets at December 31, 1999.

  At December 31, 1999, non-performing residential real estate loans totalled
$2.2 million and included 40 loans.  At March 31, 2000, non-performing
residential real estate loans totalled $1.8 million and included 33 loans.

  At December 31, 1999, there was 1 non-performing commercial real estate loan
of $53,000.  At March 31, 2000, there was 1 non-performing commercial real
estate loan of $0.9 million.

  Non-performing commercial loans at December 31, 1999 totalled $8.4 million and
included 34 individual loans ranging in size from $6,000 to $1.2 million.  At
March 31, 2000, non-performing commercial loans decreased to $8.2 million and
consisted of 36 individual loans ranging in size from $1,287 to $1.2 million.

  At December 31, 1999, the Company had $0.9 million of consumer loans 90 days
or more past due on which it was accruing interest, as compared to $0.5 million
at March 31, 2000.

  At March 31, 2000, the recorded investment in loans for which impairment has
been recognized in accordance with SFAS No. 114 totalled $4.7 million with a
corresponding valuation allowance of $1.6 million.

  At December 31, 1999, ORE totalled $0.9 million, which consisted of 10 single-
family residential properties with a book value totalling $526,000 and 4
commercial real estate properties with a book value totalling $384,000.  At
March 31, 2000, ORE totalled $744,000, which consisted of 9 single-family
residential properties totalling $405,000 million and 4 commercial real estate
properties with a book value of $339,000.

  Management reviews the adequacy of the allowance for possible credit losses at
least quarterly, applying projected loss ratios to the risk-ratings of loans
both individually and by category.  The projected loss ratios incorporate such
factors as recent loss experience, current economic conditions and trends,
trends in past due and non-accrual amounts, the risk characteristics of various
categories and concentrations of loans, transfer risks and other pertinent
factors.

  Net charge-offs decreased from $2.3 million for the first quarter of 1999 to
$2.0 million for the same quarter in 2000.  Management continues to take an
aggressive approach to the charge-off of problem loans and continues to review
the level of reserves to maintain a level of loan loss reserves that is
considered adequate to cover potential credit losses.

Sources of Funds
----------------

  Funding for the Company's assets is derived primarily from demand and time
deposits and long and short-term borrowings.  The competition for deposits
continues to be very strong in the market area and remains a focus of the Bank's
effort.  The average balance of all interest-bearing liabilities increased from
$1,989.3 million for the three-month period ended March 31, 1999 to $2,059.0
million for the same period ended March 31, 2000, an increase of $69.7 million.
The most significant increase in interest-bearing liabilities for the quarter
ended March 31, 2000 compared to March 31, 1999, was an increase in the average
balances of  certificates of deposit. The average balance of certificates of
deposit increased to $1,113.6 million for the first quarter of 2000 from
$1,020.0 million for the first quarter of 1999. A shift in balances from
checking products to money market accounts is reflected because of a retail
sweep account program maintained by the Bank. The balance at March 31, 2000 that
represented checking accounts that were swept into moneymarket accounts
approximated $90.2 million. To fund loan growth, the Bank had looked to other
areas to augment retail deposits as a source of funds.  Certificates of deposits
from a money desk decreased to an average balance of $210.7 million in the first
quarter of 2000 from a $237.8 million average balance in the same quarter in
1999.  Brokered certificates of deposit additionally remain a source of funding
for asset growth.  The average balance of these deposits grew from $97.5 million
for the first quarter of 1999 to $217.7 million for the first quarter of 2000.
With the rise in interest rates over the past year, the overall cost of funds
for all certificates of deposits increased from 5.24% to 5.54% from the first
quarter of 1999 to the same period in 2000.  Total borrowings decreased from an
average balance of $232.5 million to $141.6 million from the quarter ended March
31, 1999 to the same quarter ended March 31, 2000.  With an increase in the
average rate paid on

borrowings from 4.89% for the quarter ended March 31, 1999 to 5.55% for the same
quarter in 2000 offset by the decrease in average balance, interest expense on
these borrowings decreased from $2.8 million for the first quarter of 1999 to
$2.0 million for the first quarter of 2000.

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

  A fundamental objective of the Company is to manage its liquidity effectively.
Prudent liquidity management insures that the Company can meet all of its
contractual obligations, meet its customers' loan demands, fund all of its
operations and minimize the effects of interest rate fluctuation on earnings.
There were no material changes in the Company's liquidity or interest rate
sensitivity since December 31, 1999.

  The Company's primary sources of funds have consisted of deposits,
amortization and prepayments of outstanding loans and mortgage-backed
securities, bond maturities, and such other sources as long- and short-term
borrowings, and sales of investment securities, loans, and mortgage-backed
securities.  At March 31, 2000, the total of approved loan commitments amounted
to $88.1 million.  Long-term borrowings of $23.0 million are scheduled to mature
in the years 2002 through 2019.  Savings certificates, which are scheduled to
mature during the next 12 months, totalled $884.9 million.  Management expects
that a substantial portion of these maturing certificates will remain on deposit
with the Company.

  At March 31, 1999, the Company's Tier I leverage ratio, as defined in
regulatory guidelines, was 9.92%, which exceeds the current requirements for the
Company.  At March 31, 2000, the Company's total capital-to-risk-weighted assets
ratio, calculated under the Federal Reserve Board's risk-based capital
requirements, was 11.18%.

  The Company's book value per common share increased from $15.11 at December
31, 1999 to $15.31 at March 31, 2000.

Impact of Inflation and Changing Prices
---------------------------------------

  The financial statements and related data presented herein have been prepared
in accordance with generally accepted accounting principles which require the
measurement of financial position and operating results in terms of historical
dollars, without considering changes in the relative purchasing power of money
over time due to inflation.

  Unlike most industrial companies, virtually all of the assets and liabilities
of a financial institution are monetary in nature.  As a result, interest rates
have a more significant impact on a financial institution's performance than do
the effects of general levels of inflation.  Interest rates do not necessarily
move in the same direction or in the same magnitude as the price of goods and
services.

Other Matters
-------------

  On April 20, 2000, NBT Bancorp Inc. (NBT) and BSB Bancorp, Inc. (BSB)
announced the signing of a definitive agreement to merge. This strategic
alliance is expected to create a bank holding company with assets of $4.7
billion and proforma market capitalization of approximately $539 million. The
holding company will adopt a new name before the merger occurs. Under the terms
of the agreement, BSB stockholders will receive two shares of NBT common stock
for each share of BSB held. The merger, which has been unanimously approved by
the boards of directors of NBT and BSB, is subject to standard regulatory and
shareholder approvals. A copy of the definitive documents related to the merger
were filed under cover of Form 8-K on April 28, 2000.

Item 3

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  The Company's consolidated results of operations depend to a large extent on
the level of its net interest income, which is the difference between interest
income from interest-earnings assets (such as loans and investments) and
interest expense on interest-bearing liabilities (such as deposits and
borrowings).  If interest-rate fluctuations cause the Company's cost of funds to
increase faster than the yield on its interest-bearing assets, net interest
income will decrease.  In addition, the market values of most of its financial
assets are sensitive to fluctuations in market interest rates.  The Company
measures and manages its interest-rate risk by focusing on the Company's "gap",
which is the measure of the mismatch between the dollar amount of the Company's
interest-earning assets and interest-bearing liabilities which mature or reprice
within certain time frames.

  Based on the Company's latest analysis of asset/liability mix (December 31,
1999), management's simulation analysis of the effects of changing interest
rates on a static balance sheet projected that an immediate 200 basis point
increase in interest rates over the 12 months ended December 31, 2000 would
decrease net interest income for that period by 0.33% or less and that a similar
decrease in interest rates would increase net interest income by 0.23% or less.
The test is based on a number of assumptions and there can be no assurance that
if interest rates did move by two percent that the Company's results of
operations would be impacted as estimated.  Although the Company uses various
monitors of interest-rate risk, the Company is unable to predict future
fluctuations in interest rates or the specific impact thereof.

  Changes in interest rates can also affect the amount of loans the Company
originates, as well as the value of its loans and other interest-earning assets
and its ability to realize gains on the sale of such assets and liabilities.
Prevailing interest rates also affect the extent to which borrowers prepay loans
owned by the Company.  When interest rates increase, borrowers are less likely
to prepay their loans, and when interest rate decrease, borrowers are more
likely to prepay loans.  Funds generated by prepayment might be invested at less
favorable interest rates.  Prepayments may adversely affect the value of
mortgage loans, the levels of such assets that are retained in the Company's
portfolio, net interest income and loan servicing income.  Similarly,
prepayments on mortgage-backed securities can adversely affect the value of such
securities and the interest income generated by them.

   Increases in interest rates might cause depositors to shift funds from
accounts that have a comparatively lower cost (such as regular savings accounts)
to accounts with a higher cost (such as certificates of deposits).  If the cost
of deposits increases at a rate greater than yields on interest-earning assets
increase, the interest-rate spread will be negatively affected.  Changes in the
asset and liability mix also affect the Company's interest-rate risk.

  The Company faces substantial competition for deposits and loans throughout
its market area both from local financial institutions and from out-of-state
financial institutions that either solicit deposits or maintain loan production
offices in the Company's market area.  The Company competes for deposits and
loans primarily with other financial service providers such as savings
institutions, commercial banks, credit unions, money market funds, and other
investment alternatives.  The Company believes that its ability to compete
effectively depends largely on its ability to compete with regard to interest
rates, as well as service fees, personalized services, quality and range of
financial products and services offered, convenience of office hours and
locations, and automated services.
