NSD Bancorp
--------------------------------------------------------------------------------
 
NOTE 1-SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION:
 
The consolidated financial statements of NSD Bancorp, Inc. (the "Corporation")
include the accounts of the Corporation and wholly owned subsidiary, NorthSide
Bank, a community bank operating ten branch offices located in western
Pennsylvania, and NorthSide Bank's wholly owned subsidiary, 100 Federal Street,
Inc. Material intercompany accounts and transactions have been eliminated.
 
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS:
 
The preparation of financial statements in conformity with generally accepted
accounting principals requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and contingent liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
INVESTMENT SECURITIES:
 
The investment securities portfolio consists of securities and short-term
investments which are purchased by the Corporation to enhance the overall yield
on earning assets and to contribute to the management of interest rate risk and
liquidity. Investments in debt and equity securities are classified into three
categories: securities held to maturity, securities available for sale and
trading securities.
 
The Corporation classifies securities as held to maturity when it has both the
ability and positive intent to hold securities to maturity. Securities held to
maturity are stated at cost adjusted for amortization of premium and accretion
of discount, computed primarily under the interest method.
 
Securities not classified as held to maturity are designated as available for
sale. These securities may be sold in response to changes in market interest
rates, changes in prepayment or extension risk, asset-liability management
decisions, income tax considerations or other circumstances identified by
management. Securities available for sale are recorded at estimated market
value, with the aggregate unrealized holding gains and losses reported, net of
tax effect, as a separate component of shareholders' equity.
 
The Corporation's investment policy specifically prohibits the existence of a
trading account portfolio.
 
On a periodic basis, management evaluates each security where amortized cost
exceeds realizable value. If the decline is judged to be other than temporary,
the cost of the security is written down to estimated net realizable value with
the write-down included in net securities gains (losses). Realized gains and
losses are computed principally under the specific identification method.
 
LOANS HELD FOR SALE:
 
At December 31, 1998 and December 31, 1997, loans held for sale were comprised
entirely of student loans. These loans are carried at the lower of cost or
market value obtained through secondary market bid quotations. Any realized
gains and losses on these loans are included in other operating income.
 
LOANS AND RESERVE FOR LOAN LOSSES:
 
Loans are stated at face value, net of unearned income and deferred fees.
Installment loan unearned income is recognized over the loan term using the
interest method. Interest on all other loans is recognized based on the
outstanding principal balance of the loans. The accrual of interest is
discontinued when, in management's judgment, it is determined that the
collectibility of interest, but not necessarily principal, is doubtful. When a
loan is classified as nonaccrual, all previously accrued and unpaid interest is
reversed. Interest receipts on nonaccrual loans are applied to principal. Net
loan fees are deferred and amortized over the term of the related loan using the
interest method.
 
The reserve for loan losses is maintained at a level considered adequate by
management to provide for loan losses. The reserve is increased by provisions
charged to expense and reduced by loan losses net of recoveries. The amount
 
                                        8
<PAGE>   6
 
--------------------------------------------------------------------------------
 
of reserve is based on management's evaluation of the loan portfolio as well as
prevailing and anticipated economic conditions, specific problem loans and other
factors.
 
Within the context of Statement of Financial Accounting Standards (SFAS) No.
114, "Accounting by Creditors for Impairment of a Loan," a loan is considered to
be impaired when, based upon current information and events, it is probable that
the Corporation will be unable to collect all amounts due for principal and
interest according to the contractual terms of the loan agreement. Impairment is
measured based on the present value of expected future cash flows discounted at
a loan's effective interest rate, or as a practical expedient, the observable
market price or, if the loan is collateral dependent, the fair value of the
underlying collateral. When the measurement of an impaired loan is less than the
recorded investment in the loan, the impairment is recorded in a specific
valuation allowance through a charge to provision for loan losses. This specific
valuation allowance is periodically adjusted for significant changes in the
amount or timing of expected future cash flows, observable market price or fair
value of the collateral. The valuation allowance, or reserve for impaired loan
losses, is part of the total reserve for loan losses. Upon disposition of an
impaired loan, any related allowance is reversed through a charge to the
impaired reserve for loan losses. Cash payments received on impaired loans are
recorded as a direct reduction of the loan principal. Subsequent amounts
collected are recognized as interest income. Impaired loans are not returned to
accruing status until all amounts due, both principal and interest, are current
and there has been a demonstrated, sustained payment history.
 
Generally, management considers all major nonaccrual loans and certain
renegotiated loans for impairment. The minimum period without payment that
typically can occur before a loan is considered for impairment is ninety days.
SFAS No. 114 does not apply to large groups of smaller balance, homogenous loans
that are collectively evaluated for impairment. The Corporation collectively
reviews leases and consumer loans under $50,000, and residential and commercial
real estate under $250,000 for impairment.
 
PREMISES AND EQUIPMENT:
 
Premises and equipment are carried at original cost less accumulated
depreciation. Premises and equipment are depreciated over their useful lives
using either the straight-line or an accelerated method. Leasehold improvements
are amortized over the terms of the respective lease or the estimated useful
lives of the improvements, whichever is shorter. Costs for maintenance and
repairs are expensed currently. Major improvements are capitalized. When
premises and equipment are disposed of, the accounts are relieved of the cost
and accumulated depreciation or amortization, and any resulting gains or losses
are credited to or charged against income.
 
FORECLOSED ASSETS:
 
Foreclosed assets are comprised of other real estate owned and repossessed
collateral, which are carried at the lower of the outstanding loan balance or
estimated fair value less estimated costs to sell at the date of foreclosure.
 
INCOME TAXES:
 
Deferred income taxes result from temporary differences between financial and
tax reporting. Deferred tax assets and liabilities are determined based on
differences between financial reporting and tax basis of assets and liabilities
and are measured using the statutory tax rates.
 
INTANGIBLE ASSETS:
 
Included in other assets is a deposit premium of approximately $529,803 and
$706,404, net of accumulated amortization, at December 31, 1998 and 1997,
respectively. The premium is amortized using the straight-line method over a
five year period. The Corporation periodically evaluates the carrying value and
the remaining amortization period of the intangible asset for possible
impairment. Adjustments are recorded when the benefit of the related asset to
the Corporation decreases due to disposition of deposits relative to the deposit
premium.

--------------------------------------------------------------------------------
 
CASH EQUIVALENTS:
 
The Corporation has defined cash equivalents as cash and due from banks and
federal funds sold.
 
EARNINGS PER SHARE:
 
The Corporation adopted SFAS No. 128, "Earnings Per Share," which was issued in
February, 1997. This statement requires the disclosure of basic and diluted
earnings per share and revised the method required to calculate these amounts.
 
Basic earnings per common share is calculated by dividing net income by the sum
of the weighted average number of shares of common stock outstanding during each
period. Diluted earnings per common share is calculated by dividing net income
by the sum of the weighted average number of shares of common stock outstanding
and the number of shares of common stock which would be issued assuming the
exercise of stock options during each period.
 
Basic and diluted earnings per share calculations include the retroactive effect
of a 10% stock dividend declared January 26, 1999, a 3-for-2 stock split in
1997, a 5% stock dividend in 1997 and a 5% stock dividend in 1996.
 
RECENT ACCOUNTING PRONOUNCEMENTS:
 
In June 1997, SFAS No. 131, "Disclosure About Segments of an Enterprise and
Related Information" was issued. This standard redefines how operating segments
are determined and requires disclosure of certain financial and descriptive
information about a company's operating segments. The Corporation has determined
that it only has one operating segment which is the operation of a bank.
Therefore, the Corporation will not be presenting any further segment
information.
 
In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities" was issued. This statement establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts and for hedging activities. It applies to all
entities and requires that any entity recognize all derivatives as either assets
or liabilities in the statement of financial position and measure those
instruments at fair value. Under SFAS No. 133, the change in fair value is
reflected in the income statement or as an element of other comprehensive
income. Management is currently in the process of evaluating the impact of this
statement on the consolidated financial statements.
 
In June 1997, SFAS No. 130, "Reporting Comprehensive Income" was issued which
requires businesses to disclose comprehensive income and its components in their
general-purpose financial statements. This standard requires the reporting of
all items of comprehensive income in a financial statement that is displayed
with the same prominence as other financial statements. This statement is
effective for fiscal years beginning after December 15, 1997, with
reclassification of comparative financial statements, and is applicable to
interim periods. The Corporation has chosen to disclose comprehensive income in
the income statement, in which the components of comprehensive income are
displayed net of income taxes.

On January 1, 1996, the Corporation adopted SFAS No. 123, "Accounting for Stock
Based Compensation." As permitted by SFAS No. 123, the Bank has chosen to apply
Accounting Pronouncements Bulletin (APB) No. 25, "Accounting for Stock Issued to

NOTE 9-TRANSACTIONS WITH RELATED PARTIES
 
In the ordinary course of business, the Corporation has transactions, including
loans, with the Corporation's employees, principal officers and directors and
their related interests. Approximately 75% of related party loans are with two
Board members. A summary of loan activity for directors, executive officers and
their associates with loan balances in excess of $60,000 is as follows:

NOTE 10-COMMITMENTS, CONTINGENCIES AND FINANCIAL INSTRUMENTS WITH OFF-BALANCE
        SHEET RISK
 
The Corporation incurs off-balance sheet risk in the normal course of business
in order to meet financing needs of its customers. These financial instruments
include commitments to extend credit and standby letters of credit which
involve, to varying degrees, elements of credit and interest rate risk in excess
of the amount recognized in the consolidated financial statements.
 
At December 31, 1998, there are various outstanding commitments to extend credit
of approximately $40,125,000 and standby letters of credit of approximately
$401,000. The majority of standby letters of credit expire within the next
fifteen months. Commitments to extend credit are commitments to lend to a
customer as long as there is no violation of any condition established in the
loan agreement. Commitments generally have fixed expiration dates or
 
                                       17
<PAGE>   15

--------------------------------------------------------------------------------
 
other termination clauses and may require payment of a fee. Since many of the
commitments are expected to expire without being drawn upon, the total
commitment amounts do not necessarily represent future cash requirements. The
Corporation evaluates each customer's creditworthiness on a case-by-case basis.
 
Standby letters of credit are conditional commitments issued by the Corporation
to guarantee the performance of a customer to a third party. Those guarantees
are primarily issued to support public and private borrowing arrangements,
including normal business activities, bond financing and similar transactions.
The credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loans to customers. The Corporation requires
collateral supporting those commitments as deemed necessary.
 
The Corporation's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit and
standby letters of credit is represented by the contractual amount of those
instruments. The Corporation uses the same credit and collateral policies in
making commitments and conditional obligations as for all other lending.
Collateral for these types of commitments is similar to collateral obtained on
other commercial loans.
 
Additionally, the Corporation is subject to certain asserted and unasserted
potential claims encountered in the normal course of business. In the opinion of
management and legal counsel, neither the resolution of these claims nor the
funding of those credit commitments will have an adverse effect on the
Corporation's consolidated financial position, results of operations or cash
flows.
 
NOTE 11-CONCENTRATIONS OF CREDIT
 
The Corporation grants commercial, residential and consumer loans primarily to
customers in the Western Pennsylvania area. The Corporation has a diversified
loan portfolio which is not dependent upon any particular economic sector.
Substantially all of the Corporation's investments in municipal securities are
obligations of state or political subdivisions located within Pennsylvania. As a
whole, the Corporation's loan and investment portfolios could be affected by the
general economic conditions of Pennsylvania. In addition, at December 31, 1998,
a significant portion of the Corporation's "cash and due from banks" and
"federal funds sold" are maintained with a large financial institution located
in southwestern Pennsylvania.
 
NOTE 12-FAIR VALUE OF FINANCIAL INSTRUMENTS
 
The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practical to estimate that
value:
 
CASH AND FEDERAL FUNDS SOLD:
For those short-term instruments, the carrying amount is a reasonable estimate
of fair value.
 
INVESTMENT SECURITIES:
The estimated fair value of securities and marketable equity securities is based
on quoted market prices or dealer quotes. If a quoted market price is not
available, fair value is estimated using quoted market prices for similar
securities.
 
LOAN RECEIVABLES:
Fair values were estimated for loan portfolios with similar financial
characteristics by discounting contractual cash flows considering prepayments,
credit risk, overhead and other factors.
 
Assumptions regarding credit risk, cash flows and discount rates were
judgmentally determined using available market and internal information which
management believes to be reasonable. However, because there are no active
markets for many loan types, the Corporation has no basis to determine whether
the estimated fair value presented would be indicative of the value negotiated
in an actual sale.
 
DEPOSIT LIABILITIES:
The fair value of demand deposits, savings accounts and certain money market
deposits is the amount payable on demand as of December 31, 1998. The fair value
of the fixed-maturity certificates of deposit is estimated using the
 
                                       18
<PAGE>   16
 
--------------------------------------------------------------------------------
 
rates currently offered as of December 31, 1998 for deposits of similar
maturities. Fair value estimates do not include the value of depositor
relationships or the value of the low-cost funding provided by deposits.
 
REPURCHASE AGREEMENTS:
The fair value is estimated using the rates currently offered for borrowings
with similar terms and remaining maturities.
 
COMMITMENTS TO EXTEND CREDIT, STANDBY LETTERS OF CREDIT AND FINANCIAL
GUARANTEES:
The fair value of commitments is estimated using the fees currently charged to
enter into similar agreements, taking into account the remaining terms of the
agreements and the present creditworthiness of the counterparties. For
fixed-rate loan commitments, fair value also considers the difference between
current levels of interest rates and the committed rates. The fair value of
guarantees and letters of credit is based on fees currently charged for similar
agreements or on the estimated cost to terminate them or otherwise settle the
obligations with the counterparties at the reporting date.
 
The fair value of commitments, guarantees and letters of credit is insignificant
after considering the aforementioned factors.
 
The estimated fair values of the Corporation's financial instruments are as
follows (in thousands):

NOTE 13-REGULATORY RESTRICTIONS
 
The Corporation is subject to the regulations of certain federal and state
agencies and undergoes periodic examinations by such regulatory authorities.
Neither the Corporation nor its subsidiary is subject to written regulatory
agreements.
 
Under capital adequacy regulatory guidelines and the regulatory framework for
prompt corrective action, the Corporation must meet specific capital
requirements taking into consideration quantitative measures of assets,
liabilities and certain off-balance sheet items. Such measures are subject to
qualitative judgments by the regulators with regard to composition, risk
weightings and other factors.
 
Minimum regulatory risk-based capital ratios for tier I, total capital and
leverage are 4%, 8% and 4%, respectively. Failure to meet minimum capital
requirements can initiate certain mandatory and possible additional
discretionary actions by regulators that, if undertaken, could have a direct
material effect on the Corporation's financial statements. Management believes,
as of December 31, 1998, that the Corporation meets all capital adequacy
requirements to which it is subject.

INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
  NSD Bancorp, Inc.
 
We have audited the accompanying consolidated balance sheet of NSD Bancorp, Inc.
and subsidiary as of December 31, 1998, and the related consolidated statements
of income and comprehensive income, stockholders' equity, and cash flows for the
year then ended. These financial statements are the responsibility of the
Corporation's management. Our responsibility is to express an opinion on these
financial statements based on our audit. The financial statements of the
Corporation for the years ended December 31, 1997 and 1996, were audited by
other auditors whose report, dated January 26, 1998, expressed an unqualified
opinion on those statements.
 
We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
In our opinion, such 1998 consolidated financial statements present fairly, in
all material respects, the financial position of NSD Bancorp, Inc. and
subsidiary at December 31, 1998, and the results of their operations and their
cash flows for the year then ended in conformity with generally accepted
accounting principles.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
The following discussion is an analysis of NSD Bancorp, Inc.'s (the Corporation)
financial condition and results of operations and should be read in conjunction
with the Consolidated Financial Statements.
 
RESULTS OF OPERATIONS FOR THE YEAR
 
Net income increased to $4,167,691 or $1.46 (basic) per share in 1998, from
$3,904,710 or $1.38 in 1997 and $3,689,489 or $1.30 in 1996. Contributing to the
increase in net income were increases in net interest income of $444,985, net
investment securities gains of $12,777 and service fee income of $55,982 and
decreases in equipment and supplies expense of $19,463, FDIC insurance of $2,741
and other operating expenses of $145,376. These contributions to the overall
increase were offset by decreases in other operating income of $5,270 and
increases in the provision for loan losses of $60,000, salary and employee
benefits of $120,383, occupancy expense of $63,511, data processing costs of
$53,552, advertising of $7,362 and the provision for income taxes of $108,265.
Impacting 1997 earnings was a $289,000 loss recognized on the merchant credit
card portfolio and a $167,000 gain on the sale of land. Contributing to the
increase in 1997 net income over 1996 were increases in net interest income of
$1,055,185, net investment securities gains of $8,656, service fee income of
$41,970, other operating income of $196,275 (which includes the gain on sale of
land) and a decrease in advertising expense of $46,625. These contributions to
the overall increase were offset by increases in the provision for loan losses
of $70,000, equipment and supplies expense of $22,244, data processing costs of
$68,019, salary and employee benefits of $137,804 and the provision for income
taxes of $219,106.
 
Return on average assets (ROA) was 1.27% for 1998 compared to 1.25% for 1997 and
1.32% for 1996. Both the increase from 1997 to 1998 and the decrease from 1996
to 1997 is primarily due to the 1997 earnings being affected by the loss on the
merchant credit card portfolio offset by the gain on the sale of land. ROA
increased from 1997 to 1998 despite a decline in net interest margin from 4.81%
in 1997 to 4.69% in 1998. Return on average equity was 13.13% for 1998 compared
to 13.59% for 1997 and 14.19% for 1996. The decrease in ROE reflects the impact
of net interest margin compression and also higher average capital levels during
1998 compared to 1997.
 
NET INTEREST INCOME
 
The primary component of the Corporation's earnings is net interest income,
which is the difference between interest earned on loans, investments and other
earning assets and the interest expense on deposits and other interest bearing
liabilities which fund those assets. Tax-exempt securities and loans carry
pretax yields lower than comparable tax assets. Therefore, it is more meaningful
to analyze net interest income on a tax-equivalent basis.
 
Total interest income increased $530,802 during 1998 as a result of a
$15,744,524 increase in average earning assets offset by a decline in average
yield on earning assets from 8.19% in 1997 to 7.95% in 1998. Interest expense on
deposits decreased $239,769 as a result of a decrease in the average cost of
deposits to 4.19% in 1998 from 4.30% in 1997. Interest expense on borrowings
increased $523,971 due to an increase of $11,168,822 in average outstanding
levels offset by a decrease in the average rate paid on such balances from 5.75%
in 1997 to 5.25% in 1998.
 
Total interest income increased $2,168,959 during 1997 as the result of a
$30,336,038 increase in average earning assets offset by a decline in average
yield on earning assets from 8.31% in 1996 to 8.19% in 1997. Interest expense on
deposits increased $1,021,967 as the result of a $17,526,025 increase in the
average level of interest bearing deposits and an increase from 4.16% in 1996 to
4.30% in 1997 in the average cost of such deposits. Interest expense on
borrowings increased $234,004 due to a $3,783,050 increase in average
outstanding levels and an increase in the average rate paid on such balances
from 5.63% in 1996 to 5.75% in 1997.
 
Net interest income was $14,559,710 at December 31, 1998, compared to
$14,171,227 at December 31, 1997 and $13,259,239 at December 31, 1996. This
consistent improvement has been largely due to increases in average earning
assets.

Average earning assets for 1998 were $310,544,813 compared to $294,800,289 and
$264,464,252 in 1997 and 1996, respectively. To provide a more in depth analysis
of net interest income, the following average balance sheet and net interest
income analysis detail the contribution of earning assets to overall net
interest income and the impact of cost of funds. The rate/volume analysis shows
the portions of the net change in interest income due to changes in volume or
rate on a tax equivalent basis using the statutory federal income tax rate of
34%. Changes in net interest income due to both rate and volume in the

PROVISION FOR LOAN LOSSES
 
The Corporation's provision for loan losses was $780,000 in 1998, $720,000 in
1997 and $650,000 in 1996. The increase in the provision for loan losses was
primarily due to an increase in average loans during 1998. Net charge-offs for
1998 were $937,827, compared to $384,175 for 1997 and $747,858 in 1996.
Approximately $361,000 of the total charge-off amount for 1998 was attributable
to one customer. For additional information, see the Non-Performing Assets and
Reserve for Loan Losses sections of this discussion.
 
OTHER INCOME
 
Other income increased $63,489 from $1,586,414 in 1997 to $1,649,903. This
increase is attributable to an increase in net gains on the sale of investment
securities of $12,777 and an increase in service fees of $56,182 predominantly
due to increased efforts in the collection of NSF/overdraft fees which added
$35,454 to income over 1997. These increases were offset by a decrease in other
operating income of $5,270 which was mainly attributable to a one-time gain of
$167,000 on the sale of land in 1997. Offsetting the 1997 gain was the
introduction in 1998 of ATM surcharge fees which added $117,000 in other income
for 1998 over 1997 and an increase in gains on the sale of other assets of
$83,987 over 1997.
 
Other income increased $246,901 from $1,339,513 in 1996 to $1,586,414 in 1997.
Contributing to this increase was a one-time gain on the sale of land of
$167,000, an increase in net gains on investment securities of $8,656, an
increase in service fee income of $41,970 and increases in net gains on the
sales of lease assets and other assets of $7,173 and $19,785, respectively.
Loans sold in 1996 resulted in a gain of $14,614. There were no loans sold in
1997 resulting in an offset to the increase in other income.
 
OTHER EXPENSES
 
Total other expenses increased $77,228 from $8,950,416 in 1997 to $9,027,644 in
1998. Salary and benefits increased $120,383 to $4,273,754 in 1998 from
$4,153,371 in 1997. Salary expense increased $55,773 due to normal inflation
adjustments and growth of the organization. Employee health insurance premiums
also increased $31,449. An increase in the employer portion of payroll taxes of
$9,194 corresponded to the increase in salary expense and an increase in
temporary employee expense of $34,331 also contributed to the overall increase.
 
Occupancy expense increased $63,511 from $783,068 in 1997 to $846,579 in 1998.
This increase is due almost entirely to an increase in real estate tax expense
of $74,180 which represents the establishment of an accrual of estimated annual
real estate tax expense. A slight increase in building rent of $11,454 also
contributed to the overall increase offset by decreases in insurance expense and
building maintenance of $7,225 and $14,377, respectively. Equipment and supplies
expense decreased $19,463 during 1998 which is primarily the result of decreases
in equipment maintenance contracts, stationary and supplies expense and vehicle
expense of $23,745, $11,875 and $4,541, respectively, offset by increases in
equipment repair expense and general office expense of $22,136 and $3,774,
respectively. Data processing expense increased $53,552 to $629,397 in 1998 from
$575,845 in 1997 which was the result of an increase in contractual monthly
costs assessed by the Corporation's primary data processor and continued
increases in ATM network charges. FDIC insurance expense decreased slightly to
$37,492 in 1998 from $40,233 in 1997 due to a decrease in premium on acquired
SAIF insured deposits. Advertising expense increased slightly to $158,070 in
1998 from $150,708 in 1997. Other operating expenses decreased $145,376 to
$2,058,515 in 1998 from $2,203,891 in 1997 due to the loss of approximately
$289,000 on the merchant credit card portfolio in 1997. Disregarding this loss,
other operating expenses increased approximately $144,000 over 1997. There were
several factors contributing to this amount. Most significant was a $25,460
increase to audit expense due to the cost of a 401(k) plan review and additional
accruals for anticipated charges. An increase in financial services expense of
$20,082 was due to establishing an annual report expense accrual and
correspondent bank service charges increased $10,521. The increase in average
shareholders' equity and average assets during 1998 resulted in additional
Pennsylvania shares tax of $20,436. With a more aggressive approach to reducing
loan delinquencies during 1998, the Corporation experienced a $12,712 increase
in asset recovery expenses. An increase in ATM losses of $10,150 can be largely
attributed to a branch office robbery during

1998. These increases were offset by decreases in legal expense and deposit
premium amortization of $26,624 and $8,333, respectively.
 
Total other expenses increased $797,759 from $8,152,657 in 1996 to $8,950,416 in
1997. Salary and benefits increased $137,804 to $4,135,371 in 1997 from
$4,015,567 in 1996. Included in 1997 expenses were slight increases in the cost
of health and life insurance premiums of $17,122 and $2,876, respectively, and
an increase in the contribution to the employee profit sharing plan of $6,050.
Salary expense increased $140,668 due to normal inflation adjustments resulting
in a corresponding increase in the employer portion of payroll taxes of $10,024.
This increase was offset slightly by a decline in temporary employee expense of
$10,349.
 
Occupancy expense increased $16,199 from $766,869 in 1996 to $783,068 in 1997
primarily due to the costs associated with the addition and operation of the
Bank's downtown Pittsburgh branch office opened in December, 1996. Equipment and
supplies expense increased $22,244 during 1997 due primarily to increases in
depreciation expense, equipment expense, equipment maintenance contracts,
equipment rent expense and vehicle expense of $19,001, $35,200, $12,248 and
$4,293, respectively, offset by a decrease in equipment repair expense of
$25,572. Data processing expense increased $68,019 due primarily to the addition
of an on-line collection system and higher ATM network expenses. FDIC insurance
increased $38,233 as the Federal Deposit Insurance Corporation levied additional
assessments on the deposits of all banks insured by its Bank Insurance Fund and
also due to premiums on acquired SAIF insured deposits. Advertising expense
decreased $46,625 to $150,708 in 1997 from $197,333 in 1996. Other operating
expenses increased $561,885 from $1,642,006 in 1996 to $2,203,891 in 1997. A
significant portion of this increase is attributable to approximately $289,000
in unrecoverable charges recognized from transactions with two of NorthSide
Bank's merchant credit card customers. Although additional losses may be
incurred, it is anticipated that any future charges related to these customers
will not have any material effect on the Corporation's financial results. Also
contributing to the increase in other operating expenses was an increase in
deposit premium amortization expense of $134,935 related to deposits acquired
from another financial institution in December, 1996 and an increase in dealer
reserves and commissions of $120,893 resulting from the increased volume of
indirect automobile loans originated in 1997. Increases in postage, telephone,
legal expenses, promotions, Pennsylvania shares tax and Federal Reserve service
charges of $18,133, $18,596, $17,292, $21,400, $18,426 and $30,315,
respectively, also contributed to the overall increase. These increases were
partially offset by decreases in lease dealer commissions, asset recovery
expense, demand deposit account losses and teller shortages of $33,396, $8,925,
$16,542 and $9,800, respectively.
 
INCOME TAXES
 
The Corporation recorded an income tax provision of $1,951,715, $1,843,450 and
$1,624,344 in 1998, 1997 and 1996, respectively. The increase in the tax
provision was the result of higher pretax earnings. The effective tax rates for
1998, 1997 and 1996 were 31.9%, 32.0% and 30.5% respectively. These rates were
below the 34% statutory tax rate primarily due to the tax benefits from
tax-exempt interest income. The increases in the effective tax rates during 1997
and 1996 were primarily the result of reduced tax-exempt earnings.
 
FINANCIAL CONDITION
 
The Corporation's total assets increased $36,838,422 from $320,329,570 at
December 31, 1997 to $357,167,992 at December 31, 1998. Securities available for
sale increased $34,609,917 while securities held to maturity decreased
$1,849,739. Loans available for sale increased to $3,995,483 at December 31,
1998 from $3,419,440 at December 31, 1997. The loans available for sale at
December 31, 1998 and 1997 were entirely comprised of student loans. Net loans
decreased from $228,835,066 at December 31, 1997 to $226,196,149 at December 31,
1998.

All yields represent weighted average yields computed on the basis of cost,
adjusted for amortization of premium and accretion of discount. For purposes of
calculating yields on obligations of state and political subdivisions and
marketable equity securities, taxable equivalent adjustments were included to
provide a basis for comparison. The taxable equivalent adjustments were
calculated using the current statutory federal income tax rate of 34%. For
federal income tax purposes, corporations were allowed to exclude 70% of certain
dividend income in 1998.

LOANS
 
Loans net of deferred fees, decreased $2,102,740 during 1998, from $233,039,784
at December 31, 1997 to $230,937,044 at December 31, 1998. Improved commercial
loan development efforts resulted in an increase of $2,613,509 in commercial,
financial and agricultural loans during 1998. Decreases in residential mortgage
loans, commercial mortgages and consumer loans of $2,429,954, $1,324,175 and
$3,357,609, respectively, were primarily due to higher prepayments resulting
from the low rate environment throughout the year. Offsetting these decreases
were increases in commercial loans and lease financing of $2,613,509 and
$3,010,345, respectively.

NON-PERFORMING ASSETS

1997. The $570,257 decrease during 1998 was primarily the result of charged-off
loans related to one commercial customer. Other real estate owned increased
slightly to $191,552 in 1998 from $182,133 in 1997. Loans 90 days past due and
still accruing interest decreased $399,548 during 1998 and represent only .4% of

RESERVE FOR LOAN LOSSES
 
The Corporation's policies provide for loan loss reserves to adequately protect
against potential unidentified and/or identified loan losses consistent with
sound and prudent banking practice. These policies consider historical data of
actual losses and loans classified by specific loan credit evaluation. They also
consider loan delinquency and economic conditions.
 
The Corporation follows a loan review program to evaluate the credit risk in its
loan portfolio for substantially all loans greater than $50,000. Through the
loan review process, the Corporation maintains a classified account list which,
along with the delinquency list of loans, helps management assess the overall
quality of the loan portfolio and the adequacy of the reserve for loan losses.
Loans classified as "substandard" are those loans with clear and defined
weaknesses such as highly leveraged positions, unfavorable financial ratios,
uncertain repayment sources or poor financial condition, which may jeopardize
recoverability of the asset. Loans classified as "doubtful" are those loans
which have characteristics similar to substandard accounts but with an increased
risk that a loss may occur, or at least a portion of the loan may require a
charge-off if immediately liquidated. Although loans classified as substandard
do not duplicate loans classified as doubtful, both substandard and doubtful
loans include some loans that are delinquent or on nonaccrual status. As of
December 31, 1998, substandard loans totaled $890,129 and doubtful loans totaled
$393,793. All substandard and doubtful loans were designated as delinquent or
nonaccrual as of December 31, 1998.
 
In addition to its classified account list and delinquency list of loans, the
Corporation maintains a separate "watch list" which further aids the Corporation
in monitoring its loan portfolio. Watch list loans show warning elements where
the present status portrays one or more deficiencies requiring attention in the
short run or where pertinent ratios of the loan account have weakened to a point
that more frequent monitoring is warranted. These loans do not have all the
characteristics of a classified loan (substandard or doubtful) but do show
weakened elements as compared with those of a satisfactory credit. The
Corporation reviews these loans while assessing the adequacy of the reserve for
loan losses.
 
In order to determine the adequacy of the reserve for loan losses, management
considers the risk classification or delinquency status of loans and other
factors. Specific reserves are established for credits which management believes
require reserves greater than those allocated according to their classification
or delinquent status. For smaller loans which are not individually reviewed,
management considers delinquencies, historical charge-off experience and
economic conditions in determining the amount to be allocated to the allowance.
 
The following schedule sets forth the allocation of the reserve for loan losses
among individual loan categories. A portion is allocated to general risk to
reflect losses inherent in the loan portfolio and is based on historical
experience. The entire reserve for loan losses is available to absorb future
loan losses in any category.

LIABILITIES
 
Total liabilities were $324,773,627 at December 31, 1998, an increase of
$34,783,628 from December 31, 1997. The increases in total deposits and total
borrowed funds of $11,388,546 and $18,000,000, respectively, were used to fund
loan growth and to increase the investment portfolio as part of an overall
leverage strategy.
 
DEPOSITS
 
Total deposits increased $11,388,546 from $268,726,614 at December 31, 1997 to
$280,115,160 at December 31, 1998. Noninterest bearing and interest bearing
deposits increased during 1998 by $3,204,735 and $8,183,811 due to continued
emphasis on the development of small business relationships and strategic retail
deposit promotions.

REPURCHASE AGREEMENTS
 
At December 31, 1998, the Corporation had no outstanding repurchase agreements.
 
FHLB ADVANCES AND OTHER BORROWED FUNDS
 
At December 31, 1998, the Corporation had outstanding borrowings of $33,000,000,
of which $1,000,000 is due during 1999. The Corporation borrowed these funds to
provide liquidity for specific asset-liability management strategies. At
December 31, 1998 and 1997, the entire amount of outstanding borrowings was made
up of advances from the Federal Home Loan Bank which are collateralized by
qualifying securities and loans and are subject to restrictions or penalties
related to prepayments.
 
SHAREHOLDERS' EQUITY
 
Consolidated shareholders' equity increased $2,054,794 from $30,339,571 at
December 31, 1997 to $32,394,365 at December 31, 1998. This increase was the
result of earnings retention, the issuance of new shares of common stock for the
exercise of employee/director stock options offset by a decrease in net
unrealized holding gains on securities available for sale and dividends paid to
shareholders.
 
The Corporation continues to maintain a strong capital position. Risk-based
capital ratios exceed current regulatory requirements. The Corporation's Tier I
risk-based capital ratio at December 31, 1998 was 12.36% compared to 12.53% at
December 31, 1997. The Corporation's total risk-based capital ratio at December
31, 1998 was 14.02% compared to 13.78% at December 31, 1997. Regulatory
requirements for Tier I and total risk-based capital ratios are 4.00% and 8.00%,

MARKET RISK
 
The Corporation operates as a traditional commercial banking institution
investing in securities and loans with funding primarily provided by retail
deposits and wholesale borrowings. The primary source of revenue is the net
spread between interest earned on investments and the cost of related funding.
Inherent in this business is market risk or the risk of an adverse impact on
earnings from changes in market interest rates. Other types of market risks such
as foreign currency exchange rate risk and commodity price risk do not arise in
the normal course of the Corporation's business activities. The Corporation has
an asset/liability management process in place to monitor and control risks
associated with changing interest rates and the potential impact on future
financial performance. Management's objective is to provide an optimum return
while maintaining an appropriate mix of earning assets and funding sources
consistent with acceptable exposure to market risk. Ultimately, the Corporation
seeks to produce consistent profitability in all interest rate environments.
 
Simulation modeling enables management to quantify the extent of the
Corporation's interest rate exposure by forecasting how net interest income, and
consequently net income, varies under alternative interest rate scenarios based
on the Corporation's current position. At December 31, 1998, a simulation
analysis assuming a one-time 200 basis point increase in interest rates, results
in a negative impact of less than 1.2% or approximately $179,000 on projected
net interest income over a one-year period. Conversely, a 200 basis point
decrease in interest rates resulted in a slight increase in projected net
interest income of .1% or approximately $19,000 over the same period. These
findings are the result of normal projected growth in interest earning assets
and interest related liability levels based on the Corporation's position at
December 31, 1998. The results reflect the impact of a relatively short
repricing or rate adjustment period of the Corporation's loan products and the
effect of investment security prepayments matched with the relative short term
nature of interest sensitive deposit and borrowing liabilities. In a rising rate
environment, the increased cost of funding would be offset by increases in
yields on prime rate, LIBOR and Treasury indexed loans and securities and the
repricing of significant cash flow in the consumer loan portfolio. In a
declining rate environment, the declining yield on loans and securities due to
prepayments and index adjustments would be offset by a shortening of deposit
maturities and the repricing of a significant interest bearing demand deposit
portfolio. In any event, a sudden, substantial and protracted shift in interest
rates may adversely impact the Corporation's earnings to the extent that the
interest rates on interest earning assets and interest bearing liabilities
change at varying frequencies and market forces may limit the ability to
appropriately respond to such changes.
 
Interest rate risk is also analyzed by comparing the maturity and repricing
relationships between interest earning assets and interest bearing liabilities
at specific points in time of "GAP" analysis. Management, however, recognizes
that a simplified GAP analysis may not adequately reflect the degree to which
assets and liabilities with similar repricing characteristics react to changes
in market interest rates. In addition, repricing characteristics

identified under a specific GAP position may vary significantly under different
interest rate environments. Therefore, simulation modeling is also performed to
evaluate the extent and direction of the Corporation's interest rate exposure
under upward and downward changes in interest rates.
 
Based upon historical trends, the Corporation has typically considered all
demand and savings deposits as core deposits and relatively non-rate sensitive.
The following table has been prepared, as required, presenting interest bearing
demand deposits and savings deposits as repricing within the earliest period. As
a result, the table reflects negative, or liability sensitive, cumulative
interest GAP position of $78,982 in the first one-year GAP. Results of
simulation modeling and historical experience indicate, however that the overall
potential effect on net interest income should not have an adverse result on
future financial performance.
 
The following table summarizes the Corporation's interest rate sensitivity or
GAP position, which is the estimated aggregate maturity/repricing structure of
interest earning assets and interest bearing liabilities, at December 31, 1998

YEAR 2000 CONSIDERATIONS
 
In 1997, the Corporation initiated the process of analyzing its information
systems and vendor supplied application systems to identify and resolve any year
2000 issues concerning its business or operations. Senior management views this
initiative as one of the highest priorities of the Corporation. With oversight
from the Board of Directors, the Corporation is aggressively pursuing
appropriate solutions and assurances with regard to compliance of all
applications affected by the year 2000. As of December 31, 1998, the Corporation
had completed its assessment of all hardware, software, core business
applications and data exchange interfaces and is well into the process of
renovating systems and applications and validating year 2000 readiness.
Management expects to achieve compliance for all critical systems and
substantially all non-critical systems by the end of the second quarter of 1999.
 
All commercial loan customers with significant loan exposures have been
contacted to emphasize the importance of adequately preparing for year 2000
issues and to assess the state of their year 2000 readiness. The Corporation
could experience losses due to the interruption of a loan customer's business
caused by year 2000 related problems. As of December 31, 1998, there appears to
be no significant additional exposure to loan losses due to year 2000 related
issues. There is, however, no assurance that customers will not experience a
year 2000 related business interruption resulting in a potentially material
adverse effect on NSD Bancorp's financial condition or

results of operation. Management intends to continue its monitoring and
assessments throughout 1999 to mitigate any such losses.
 
Non-information technology systems such as the elevator, HVAC, security systems
etc., have been reviewed to determine if there are any significant year 2000
issues. Any non-compliant system or related equipment has either already been
replaced or is in the process of being replaced before the year 2000.
 
It is estimated that the total cumulative cost to the Corporation of this
process will approximate $750,000 which includes costs associated with modifying
existing systems, purchasing or leasing certain hardware and software and the
acceleration of depreciation on items which will be disposed prematurely due to
noncompliance. The majority of such costs will be incurred during 1999.
Purchased hardware and software will be capitalized in accordance with normal
policy. Personnel and all other costs related to this process are being expensed
as incurred.
 
Although the Corporation believes that it will be year 2000 compliant, any
unforeseen system failures could result in a compromise in the Corporation's
ability to service customers and could have a potentially adverse impact on NSD
Bancorp's financial condition or results of operations. A Contingency and
Business Resumption Plan is in the process of being developed to help insure
that the Corporation is prepared in the event of an automated information system
failure and to address liquidity concerns due to possible public demands for
cash.
 
LIQUIDITY AND CASH FLOWS
 
Liquidity is the ability to generate cash flows or obtain funds at a reasonable
cost to satisfy customer credit needs and the requirements of depositors. Liquid
assets include cash, federal funds sold, investments maturing in less than one
year and loan repayments. The Corporation's ability to obtain deposits and
purchase funds at reasonable rates determines its liability liquidity. As a
result of liquid asset management and the ability to generate liquidity through
deposit funding, management feels that the Corporation maintains overall
liquidity sufficient to satisfy customer needs. In the event that such measures
are not sufficient, the Corporation has established alternative sources of funds
in the form of wholesale borrowings and repurchase agreements.
 
Operating activities provided net cash of $10,573,914 during 1998, compared to
$4,679,545 and $4,910,907 for 1997 and 1996, respectively. The primary source of
operating cash flows for 1998 was net income adjusted for the effect of noncash
expenses such as the provision for loan losses, depreciation of premises and
equipment and amortization of intangible assets.
 
Investing activities used cash of $31,358,696 during 1998, compared to
$19,610,435 and $37,778,471 for 1997 and 1996, respectively. A significant
portion of borrowings were invested in investment securities available for sale
as part of an overall leverage strategy. Proceeds from the sales, repayments and
maturities of investment securities available for sale and held to maturity were
reinvested primarily in investment securities available for sale. Cash flows
from investing activities were primarily used to fund the growth in the loan
portfolio in 1997 and 1996.
 
Financing activities provided cash of $27,424,481, $9,675,632 and $41,664,124
during 1998, 1997 and 1996, respectively. Increases in demand deposits, savings
deposits, time deposits and borrowings provided cash while cash was used by
payment of cash dividends and the purchase of treasury stock. During 1997, an
increase in demand deposits, savings deposits and borrowings provided cash while
cash was used by payments of cash dividends, repayment of repurchase agreements
and a slight decrease in certificates of deposit. Net proceeds from borrowings
were used to fund growth in the investment portfolio during 1998 and loan growth
during 1997.
