BSB BANCORP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 1999

(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, 1998 data in the Consolidated Statements of Condition is derived from
     the audited consolidated financial statements included in the Company's
     1998 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 1998 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, 1999 and 1998.

4.      On July 24, 1998, the Company placed $30 million of 30-year 8.125%
        capital securities through BSB Capital Trust I (the "Trust"), a Delaware
        business trust. The Trust was formed by the Company solely to invest the
        proceeds from the sale of the capital securities in 8.125% junior
        subordinated debentures issued by the Company with a principal amount of
        $30 million and a maturity date of July 31, 2028. The junior
        subordinated debentures are the sole assets of the Trust. The net
        proceeds from the sale of the capital securities qualify as Tier I
        Capital for the Company.
 
5.      On January 25, 1999, the Company entered into an agreement to acquire
        Skaneateles Bancorp, Inc., the holding company for Skaneateles Savings
        Bank, in a tax-free, stock-for-stock exchange. The Company expects to
        issue approximately 1.4 million shares of stock in exchange for the
        outstanding shares of Skaneateles Bancorp stock which is estimated to
        result in a .970 exchange ratio. The transaction is subject to
        regulatory and shareholder approval. Skaneateles Savings Bank operates
        nine banking offices in the Onondaga and Oswego Counties of New York
        State and had $276.1 million of assets and $19.1 million of
        shareholders' equity at December 31, 1998. Pending approval of the
        Skaneateles Savings Bank shareholders on June 24, 1999, this transaction
        is expected to be completed in the second or third quarter of 1999.

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

General
-------

  BSB Bancorp, Inc. (the "Company"), the bank holding company for BSB Bank &
Trust Company (the "Bank"), earned net income of $5.3 million, or diluted
earnings per share of $0.60 for the quarter ended March 31, 1999, as compared to
net income of $4.5 million, or diluted earnings per share of $0.51 for the
quarter ended March 31, 1998.

  On April  26, 1999, the Board of Directors announced a quarterly cash dividend
of $0.25 per share payable on June 10, 1999 to shareholders of record at the
close of business on May 25, 1999.

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

  Total assets of the Company increased from $1,859.1 million at December 31,
1998 to $1,949.1 million at March 31, 1999. During the first three months of
1999, the Company originated $86.0 million of commercial loans, which
contributed to a net increase in the commercial loan portfolio of $99.0 million
from $772.8 million at December 31, 1998 to $871.8 million at March 31, 1999.
The interest rates on these loans are generally tied to the Bank's Prime Rate.
Consumer loans increased from $359.2 million at December 31, 1998 to $372.9
million at March 31, 1999, and during this period, the Company originated $51.5
million in consumer loans.  Real estate loans increased from $230.9 million at
December 31, 1998 to $240.7 million at March 31, 1999. During the above
mentioned period, the Company originated $55.4 million of real estate loans, of
which $46.9 million were sold.   Investment securities decreased from $407.2
million at December 31, 1998 to $385.1 million at March 31, 1999.

  Total deposits increased from $1,472.7 million at December 31, 1998 to
$1,521.6 million at March 31, 1999.  This growth came mainly from certificates
of deposits originated through the money desk which was established in the
second half of 1997.  These funds grew to $260.2 million at March 31, 1999 from
$199.1 million at December 31, 1998, and successfully provided the Bank with the
funds needed for the growth in assets.  Interest credited to depositors and
interest paid on borrowings totaled  $19.2 million during that three-month
period, as compared to $17.2 million for the first quarter of 1998.  The
Company's borrowings increased from $213.8 million at December 31, 1998 to
$246.8 million at March 31, 1999.  Borrowings at March 31, 1999 consisted of
$120.0 million of Federal Home Loan Bank advances and $86.9 million of a Federal
Home Loan Bank line of credit.  Of the remaining $39.9 million, $38.0 million
are securities sold under agreement to repurchase.  These borrowings are used to
fund the Company's lending and investing activities.

  Shareholders' equity increased from $135.0 million to $137.4 million during
the first three months of 1999.  This increase is a result of earnings of $5.3
million, $301,000 of stock options exercised during the period, and a $1.0
million decrease in unrealized appreciation in securities available for sale.
This increase in shareholders' equity was partially offset by cash dividends
paid to shareholders of $2.2 million.

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 future such
losses, operating expenses, the level of other income, including gains or losses
on sale of loans and securities, and other fees.

</TABLE>

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

  The Company's interest income on interest-earning assets increased from $33.5
million for the three months ended March 31, 1998 to $37.5 million for the three
months ended March 31, 1999.  This increase in interest income was the result of
an increase in the average balance of interest-earning assets from $1,515.6
million to $1,799.4 million for the three months ended March 31, 1998 and March
31, 1999, respectively.  The average yield on interest-earning assets decreased
from 8.85% to 8.34% for the three months ended March 31, 1998 and 1999,
respectively.  This was impacted by three decreases in the Company's Prime Rate
of 25 basis points each during the 4th quarter of 1998.

  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 $136.8 million from the first quarter of 1998 to
$794.2  million for the first quarter of 1999.  The average yield on commercial
loans decreased from 9.65% for the first quarter of 1998 to 8.70% for the first
quarter of 1999.  The Prime Rate was 8.50% for all of the first quarter of 1998
and fell to 7.75% during 1998, which was in effect for all of the first quarter
of 1999.  Despite this decline in rates, interest income on commercial loans
rose to $17.3 million for the first quarter of 1999 from $15.9 million for the
same period in 1998.

  Despite high levels of competition in the Company's lending markets, the
average balance of consumer loans increased 19.5% to $361.8 million for the
three-month period ended March 31, 1999 compared to $302.7 million for the
three-month period ended  March 31, 1998.  This was accompanied by a rise in
yield on these assets to 9.66% from 9.56% for the first quarter of 1998. 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.   This provided an increase in
interest income to $8.7 million from $7.2 millions in the first quarter of 1998.

  The average balance of real estate loans decreased $17.3 million to $230.4
million for the quarter ended March 31, 1999 compared to the quarter ended March
31, 1998. This period reflected a decrease in yield from 8.54% to 8.10%, and the
reduced average balance resulted in a net decline of $627,000 in interest income
from real estate loans to $4.7 million.  Although residential mortgage loans
reflect a steadily declining percentage of the Bank's total loan portfolio, the
Bank continues to originate a significant amount of fixed-rate residential
mortgage loans for sale in the secondary market, while retaining servicing
rights for most of the sales in order to generate fee income.

  The average balance of investment securities increased from $298.4 million for
the first quarter of 1998 to $399.1 million for the first quarter of 1999.
Yields on investment securities decreased for this same period from 6.65% to
6.55%; the interest income 

                                       11

Item 2 - continued

on investment securities increased $1.6 million for the comparative quarters.

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

  Total interest expense increased by $2.0 million for the quarter ended March
31, 1999 as compared to the same period in 1998. The average balance of all
interest-bearing liabilities increased from $1,453.6 million for the quarter
ended March 31, 1998 to $1,742.1 million for the quarter ended March 31, 1999.
This increase accompanies a decrease in the average rate paid on all interest-
bearing liabilities from 4.75% to 4.42% during the respective period. The
average balance of deposits increased from $1,259.9 million during the three
months ended March 31, 1998 to $1,492.2 million during the same period in 1999.
The increase in the average balance of deposits was the major factor
contributing to an increase in interest paid on deposits from $14.5 million for
the first quarter of 1998 to $16.0 million for the first quarter of 1999.
Another component of the change in interest-bearing liabilities is the increase
in average balance of borrowings from $193.7 million for the three months ended
March 31, 1998 to $219.9 million for the three months ended March 31, 1999. This
increase offset a decrease in the rate paid on borrowings from 5.60% to 4.82%
during the three-month period as borrowing costs remained stable at $2.7 million
for the three months ended March 31, 1999. The utilization of borrowings to
fulfill the demand in loan growth has contributed to higher interest expense.
With generally higher costs than retail deposits, borrowing costs have
contributed to a narrowing of the spread between the Company's interest-earning
assets and interest-bearing liabilities.  Though the interest rate spread is
narrowed by these higher costs, this relationship provides continued growth in
net interest income.

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

  The provision for credit losses increased from $2.8 million to $3.2 million
for the quarters ended March 31, 1998 and March 31, 1999, respectively.  The
allowance for  possible credit losses increased to $23.2 million as of March 31,
1999, compared to $22.2 million as of December 31, 1998.  The increase in
provisions reflects, in part,  the Bank maintaining an allowance to period
ending loans at a level management, based on its experience, deems adequate to
cover potential credit losses.  See "Non-performing Loans and ORE".  Management
considers this level of reserves adequate to cover potential credit losses.

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

  Non-interest income increased 29.1% from $1.7 million to $2.2 million for the
three months ended March 31, 1998 to March 31, 1999, respectively. The major
factors attributing to this increase comparing first quarter of 1998 to the same
quarter of 1999 were an increase of $230,000 in miscellaneous other charges,
commissions, and fees, a $80,000 increase in service charges on deposit
accounts, a $65,000 increase in fees and commissions on brokerage services,  a
$64,000 increase in mortgage servicing fees, $38,000 in credit card fees, and a
$21,000 increase in trust fees.  A non-recurring income item of $146,000 was
also received during the quarter.

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

  Losses on sale of securities were $144,000 for the first quarter of 1998 and
$396,000 for the three months ended March 31, 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.

                                       12
<PAGE>
 
Item 2 - continued

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

  The practice of the Company has been to sell or securitize long-term, fixed-
rate residential mortgage loans.  This provides liquidity to fund shorter-term,
or more rate-sensitive assets, and collateral to provide borrowing for lending
activities.  As a result of this practice, the Company securitized or sold $46.9
million and $27.2 million for the first quarter of 1999 and 1998, respectively.
This resulted in losses of $44,000 and $247,000 for the same two periods,
respectively.

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

  Non-interest expense increased from $7.4 million for the quarter ended March
31, 1998 to $8.3 million for the quarter ended March 31, 1999.  Several factors
contributed to this increase.  Salaries, pensions, and other employee benefits
rose $341,000 from the first quarter of 1998.  Of this increase, $160,000 was
attributed to increased costs associated with pension and health care benefits.
As the volume of transactions rises due to growth in assets, such as credit card
loans and with greater levels of deposits, such as brokered deposits, service
expenses associated with these assets and liabilities also rise.  This resulted
in approximately a $56,000 increase in expense in the first quarter of 1999
compared to the same quarter in 1998.  New customer services and products needed
to manage these services contributed approximately $310,000 to the increase in
services expense, with corresponding increases in the number of employees to
handle the new services and expanded growth of the Bank.

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

  The income tax expense was $2.9 million and $3.2 million for the quarters
ended March 31, 1998 and March 31, 1999, respectively.  These increases were
mainly due to increased levels of taxable income and changes in tax-exempt
investment and loan portfolios.

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.

  Total non-performing loans and ORE, which is defined to include property
acquired by foreclosure or by deed in lieu of foreclosure, increased to $17.4
million, or 0.89% of total assets at March 31, 1999, compared to $16.0 million,
or 0.86% of total assets at December 31, 1998.

  At December 31, 1998, 36 non-performing residential real estate loans totalled
$1.7 million.  At March 31, 1999, non-performing residential real estate loans
totalled $1.8 million and included 34 loans.

  At December 31, 1998, non-performing commercial real estate loans totalled
$276,000.  At March 31, 1999, non-performing commercial real estate loans
increased to $277,000 and consisted of two loans of $87,000 and $190,000.

  Non-performing commercial loans at December 31, 1998 totalled $11.4 million
and included 62 individual loans ranging in size from $2,000 to $1.2 million.
At March 31, 1999, non-performing commercial loans increased to $12.1 million
and consisted of 63 individual loans ranging in size from $2,000 to $1.2
million.

  The Company's policy is to charge-off all consumer loans before they become
non-accrual.  At December 31, 1998, the Company had $513,000 of loans 90 days or
more past due on which it was accruing interest, as compared to $1.2 million at
March 31, 1999.

  At March 31, 1999, the recorded investment in loans for which impairment has
been recognized in accordance with SFAS No. 114 totalled $12.1 million with a
corresponding valuation allowance of $4.4 million.

  At December 31, 1998, ORE totalled $2.1 million, which consisted of  three
single-family residential properties with a book value totalling $77,000 and
eight commercial real estate properties with a book value totalling $2.0
million.  At March 31, 1999, ORE totalled $2.1 million, which consisted of five
single-family residential properties totalling $169,000 and seven commercial
real estate properties with a book value of $1.9 million.  A sale of one of the
commercial properties that is carried in ORE at $1.0 million is pending, but not
consummated.  If the transaction is to be carried out, minimal gain or loss is
expected on the sale.

  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.

</TABLE> 

     Net charge-offs increased from $2.1 million for the first quarter of 1998
to $2.2 million for the same quarter in 1999. Management continues to take an
aggressive approach to the charge-off of problem loans and continues to add to
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
$1,453.6 million for the three-month period ended March 31, 1998 to $1,742.1
million for the same period ended March 31, 1999, an increase of $288.5 million.
The most significant increase in interest-bearing liabilities for the quarter
ended March 31, 1998 compared to March 31, 1999, was an increase in the average
balance of certificates of deposit of $188.3 million from the first quarter of
1998 to the first quarter of 1999 from $734.4 million to $922.7 million,
respectively. To fund loan growth, the Bank looked to other areas to augment
retail deposits as a source of funds. Certificates of deposits from a money desk
have grown to an average balance of $238.1 million in the first quarter of 1999
from a $75.0 million average balance in the same quarter in 1998. Municipal
deposits have grown from an average balance of $92.3 million for the first
quarter of 1998 to $96.9 million for the first quarter of 1999. With the use of
funds that normally carry somewhat higher rates, the overall cost of funds for
all certificates of deposits declined from 5.64% to 5.25% from the first quarter
of 1998 to the same period in 1999. Total borrowings increased from an average
balance of $193.7 million to $219.9 million for 

                                       15

Item 2- continued

the quarter ended March 31, 1998 to the same quarter ended March 31, 1999. With
a decrease in the average rate paid on borrowings from 5.60% for the quarter
ended March 31, 1998 to 4.82% for the same quarter in 1999 offset by the
increase in average balance, interest expense on these borrowings remained
stable at $2.7 million for the first quarter of 1998 and the first quarter of
1999.

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, 1998.

  On July 24, 1998, the Company placed $30 million of 30-year 8.125% capital
securities through BSB Capital Trust I (the "Trust"), a Delaware business. The
Trust was formed by the Company to invest the proceeds from the sale of the
capital securities in 8.125% junior subordinated debentures issued by the
Company. The junior subordinated debentures, which have a principal amount of
$30.0 million and a maturity date of July 31, 2028, are the sole assets of the
Trust. The net proceeds from the sale of the capital securities qualify as Tier
I Capital for the Company.

  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, 1999, the total of approved loan commitments amounted
to $129.3 million.  Long-term borrowings of $70.0 million are scheduled to
mature in 2008.  Savings certificates, which are scheduled to mature during the
next 12 months, totalled $818.4 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 7.54%, which exceeds the current requirements for the
Company.  At March 31, 1999, the Company's total capital-to-risk-weighted assets
ratio, calculated under the Federal Reserve Board's risk-based capital
requirements, was 10.25%.

  The Company's book value per common share increased from $15.64 at December
31, 1998 to $15.85 at March 31, 1999.

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.

Year 2000 Compliance
--------------------

  The Year 2000 brings with it potential issues to all organizations who use
computers in the conduct of their business or depend on business associates who
use computers. To the extent computer use is date-sensitive, hardware or
software that recognizes the year by the last two digits may erroneously
recognize "00" as 1900 rather than 2000, which could result in errors or system
failures.

  The Company utilizes a number of computers and computer software (systems) in
the conduct of its business. Many systems are for specific business segments and
others have broader corporate-wide use. In 1995, the Company initiated a review
of Year 2000 and its impact. With this review, a strategic plan to address the
issues and maintain the technological standards of the hardware and software
within the Company was incorporated. This plan was initiated and approved by
senior officers
                                       16

Item 2 - continued

within the Company and is revisited at least quarterly to ensure portions of the
plan are completed as scheduled and progress is continuing with any problems
being addressed. This plan included the following steps:

 .  Awareness: Since 1995, the Company has been aware of the Year 2000 problem
   and increased the awareness of all staff, vendors, and customers to the
   problem.

 .  Assessment: Inventories of all systems, hardware, media, interfaces, internal
   programs and databases, vendor packages, and networks have been made and are
   updated as needed. Communication with vendors to ascertain their status, plan
   and upgrades for Year 2000 compliance was implemented.

 .  Renovation: Since 1995, the Company has formulated and completed two
   initiatives to maintain high quality data processing on an on-going basis.
   Year 2000 issues were addressed within the larger issue of maintaining the
   highest quality data processing available. In 1995, a Branch Automation
   Project was started and continued into 1996. In 1996, a Back Office
   Automation Project was completed. This provided the Company with Year 2000
   compliant back office hardware and most software to address the concerns of
   both technology modernization and Year 2000 issues. In October 1998, the
   Company converted to M&I Data Services, which provides data service to all
   core processing and delivery systems. The M&I system is certified compliant
   by the Information Technology Association of America.

 .  Validation: Testing of all hardware and software is being conducted on an
   independent Local Area Network that has been established at the Company
   solely for that purpose. All systems have been renovated and are Year 2000
   operational including computer equipment and peripherals, internal data
   processing and information systems, vendor provided software, outsourced EDP
   solutions, business equipment, and physical systems. The Company and its
   vendors have tested all systems for Year 2000 readiness. In addition, the
   Company has upgraded its Business Recovery Plan and has developed a Year 2000
   Contingency Plan.

 .  Implementation: Saturday, January 1, 2000 will be treated as a data
   processing conversion. Contingency plans have been developed and much of the
   testing has been completed. The Bank has tested its capability to handle
   communication and power outages as well as auxiliary Bank software systems
   malfunctions. The testing has been successful with the remainder to be
   completed in 1999.

   Contact with significant vendors and commercial loan customers was made.
Commercial loan customers were asked to fill out a survey so assessment of their
status with regard to the complications of the upcoming Year 2000 issues and
their readiness for that time could be determined. Significant vendors were
queried as to their ability to continue to supply their product without delay
with the passing of Year 2000. Of course, the response of certain third parties
is beyond control of the Company.

   Year 2000 compliance costs pertaining to internal staff incurred cumulatively
through March 31, 1999 have been approximately $85,000. An additional $40,000 is
expected in 1999 for these same costs. Direct capital expenditures have neared
$70,000 thru 1998 with an additional $30,000 expected in 1999. These costs do
not include normal ongoing costs for computer hardware (including ATM's) and
software that have been incurred or would be replaced in the next year even
without the presence of the Year 2000 Issue as these pertain to the ongoing
programs for updating the Company's delivery infrastructure.

   Despite the Company's efforts in regards to the Year 2000 Issue, there can be
no assurance that partial or total systems interruptions or the costs necessary
to update hardware and software would not have a material adverse effect upon
the Company's business, financial condition, results of operations, and business
prospects.

  Statements in Management's Discussion and Analysis are forward-looking
statements within the meaning of the Securities Act of 1933 as amended and the
Securities Exchange Act of 1934 as amended.  Actual results, performance, or
developments may differ materially from those expressed or implied by such
forward-looking statements as a result of market uncertainties and other factors
related to Internet-based businesses.  The financial services market generally,
and the market for the Company's products and services specifically, is
characterized by a high degree of competition and rapidly changing local,
national, and global market, financial and economic conditions.   Such
developments, as well as unforeseen developments in the financial services
industry, could have an adverse impact on the Company's financial position and
results of operations.

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 (August 31,
1998), management's simulation analysis of the effects of changing interest
rates projected that a gradual 200 basis point increase in interest rates over
the 12 months ending August 31, 1999 would decrease net interest income for that
period by 4.27% or less and that a similar decrease in interest rates would
increase net interest income by 4.31% 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.
