statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The
accompanying unaudited consolidated financial statements were prepared in
accordance with the instructions for Form 10-Q. For further information, refer
to the Company's consolidated financial statements and footnotes thereto
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1997. Certain items in the 1997 financial statements and footnotes have been
reclassified in order to conform with the 1998 financial statement and footnote
presentation.

            The Company is a Pennsylvania corporation which is the holding
company for Commonwealth Bank ("Bank"). Headquartered in Norristown, PA,
Commonwealth Bank has offices located in Berks, Bucks, Chester, Delaware,
Lebanon, Lehigh, Montgomery, and Philadelphia Counties, Pennsylvania. ComNet
Mortgage Services ("ComNet'), a division of the Bank, has offices in
Pennsylvania, Connecticut, New Jersey, Rhode Island, and Virginia. ComNet
operates under the trade name of Homestead Mortgage in Maryland.

2.          Principles of Consolidation

            The accompanying consolidated financial statements include the
accounts of Commonwealth; Commonwealth Bank; CFSL Investment Corporation;
Commonwealth Investment Corporation of Delaware, Inc.; ComLife, Inc.; CS
Corporation; Firstcor, Ltd.; and QME, Inc. All material intercompany accounts
and transactions have been eliminated in consolidation.

3.          Shareholders' Equity

            On June 16, 1998, the Board of Directors declared a $0.08 per share
cash dividend for the quarter ended June 30, 1998, which was made payable to
shareholders of record at the close of business on June 26, 1998. This dividend
was paid on July 10, 1998. During the second quarter of 1998, the Company
purchased 0.8 million shares of treasury stock, at an average cost of $23.71 per
share, for an aggregate purchase of $19.3 million. On June 22, 1998, the Board
of Directors authorized the repurchase of up to 0.8 million shares, or
approximately 5 percent, of its outstanding common stock. This repurchase
program represents Commonwealth's fourth such program in the past two years. In
the previous three programs, a total of 2.6 million shares were repurchased at
an average price of $18.70 per share.

4.          Future Accounting Pronouncements

            In June 1998, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting
for Derivative Instruments and Hedging Activities." The statement establishes
accounting and reporting standards requiring that every derivative instrument
(including certain derivative instruments embedded in other contracts) be
recorded in the balance sheet as either an asset or liability measured at its
fair value. The statement requires that changes in the derivative's fair value
be recognized currently in earnings unless specific hedge accounting criteria
are met. Special accounting for qualifying hedges allows a derivative's gains
and losses to offset related results on the hedged item in the income statement,
and requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

            SFAS No. 133 is effective for fiscal years beginning after June 15,
1999. A company may also implement the statement as of the beginning of any
fiscal quarter after issuance (that is, fiscal quarters beginning June 16, 1998
and thereafter). SFAS No. 133 cannot be applied retroactively and must be
applied to derivative instruments and certain derivative instruments embedded in
hybrid contracts that were issued, acquired, or substantively modified after
December 31, 1997 (and, at the company's election, before January 1, 1998).
Commonwealth has not yet quantified the financial statement impacts of adopting
SFAS No. 133 and has not determined the timing of or method of the adoption of
SFAS No. 133. However, the Statement could increase volatility in earnings and
other comprehensive income.

            SFAS No. 131 "Disclosures about Segments of an Enterprise and
Related Information" was issued in June 1997. This statement is effective for
fiscal years beginning after December 15, 1997, and need not be applied to
interim statements in the initial year of application. SFAS No. 131 introduces a
new model for segment reporting, called the "management approach." The
management approach is based on the way the chief operating decision maker
organizes segments within a company for making operating decisions and assessing
performance. Reportable segments are based on product and services, geography,
legal structure, management structure - any manner in which management
disaggregates a company. The management approach replaces the notion of industry
and geographic segments in current FASB standards. The Company intends to report
information on two segments as a result of the adoption of SFAS No. 131, the
Banking Operations and the Mortgage Operations.

5.          Earnings Per Share

            In February 1997, SFAS No. 128, "Earnings per share," was issued.
This statement specified the computation, presentation, and disclosure
requirements for earnings per share ("EPS"). The main objectives of the
statement were to simplify the EPS calculation and to make EPS comparable on an
international basis. Effective for both interim and annual periods ending after
December 15, 1997, primary and fully diluted EPS have been replaced by basic and
diluted EPS. Prior period results have been restated. The most significant
difference is that basic EPS no longer assumes potentially dilutive securities
in the computation. Calculating EPS under the new method has no material impact
on previously reported 1997 EPS figures.

            Basic EPS is calculated by dividing net income available to common
shareholders by the weighted average number of common shares outstanding during
the period, adjusted for Employee Stock Ownership Plan ("ESOP") shares that have
not been committed to be released, and the effects of shares held by the
Recognition Plans. Options, warrants, and other potentially dilutive securities
and treasury shares are excluded from the basic calculation, as follows:

            Diluted EPS is computed by dividing net income available to common
shareholders by the weighted average number of shares of common stock
outstanding during the period, adjusted for ESOP shares that have not been
committed to be released, and the effects of shares held by the Recognition
Plans. The effect of diluted securities, such as stock options and Recognition
Plan stock, are considered common stock equivalents and are included in the
computation of the number of outstanding shares using the treasury stock method.
Common shares outstanding exclude treasury shares.

            Basic EPS was $0.10 for the quarter ended June 30, 1998, compared to
$0.24 per share for the quarter ended June 30, 1997. Diluted EPS was $0.10 for
the quarter ended June 30, 1998, compared to $0.23 per share for the quarter
ended June 30, 1997.

            Basic EPS was $0.36 for the six months ended June 30, 1998, compared
to $0.53 per share for the six months ended June 30, 1997. Diluted EPS was $0.34
for the six months ended June 30, 1998, compared to $0.51 per share for the
six months ended June 30, 1997.

6.          Comprehensive Income

            SFAS No. 130, "Reporting Comprehensive Income" was issued in July
1997. The Company adopted SFAS No. 130 on January 1, 1998, as required. SFAS No.
130 established standards for the reporting and display of comprehensive income
and its components. The main objective of the statement is to report a measure
of all changes in equity that result from transactions and other economic events
of the period other than transactions with owners. Such components of total
comprehensive income for the Company are net income and unrealized gains on
marketable securities, net of tax, as follows:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

            When used in this Form 10-Q, or in future filings by the Company
with the Securities and Exchange Commission, in the Company's press releases or
other public or shareholder communications, or in oral statements made with the
approval of an authorized executive officer, the words or phases "will likely
result", "are expected to", "will continue", "is anticipated", "estimate",
"project", or similar expressions are intended to identify "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. Such statements are subject to certain risks and uncertainties
including changes in economic conditions in the Company's market area, changes
in policies by regulatory agencies, fluctuations in interest rates, demand for
loans in the Company's market area and competition that could cause actual
results to differ materially from historical earnings and those presently
anticipated or projected. The Company wishes to caution readers not to place
undue reliance on any such forward-looking statements, which speak only as of
the date made. The Company wishes to advise readers that the factors listed
above could affect the Company's financial performance and could cause the
Company's actual results for future periods to differ materially from any
opinions or statements expressed with respect to future periods in any current
statements.

            The Company does not undertake, and specifically disclaims any
obligation, to publicly release the result of any revisions which may be made to
forward-looking statements to reflect events or circumstances after the date of
such statements or to reflect the occurrence of anticipated or unanticipated
events.

            GENERAL. The Company is a Pennsylvania corporation which is the
holding company for the Bank. Commonwealth Bank is a federally chartered stock
savings bank, primarily regulated by the Office of Thrift Supervision ("OTS").
The Bank conducts business from its executive offices in Norristown,
Pennsylvania and, as of June 30, 1998, 58 full-service offices located in
southeast Pennsylvania. ComNet Mortgage Services, a division of the Bank, also
located in Norristown, conducts business through loan origination offices
located in Pennsylvania, Connecticut, New Jersey, Rhode Island, and Virginia,
and operates under the trade name of Homestead Mortgage in Maryland. ComNet also
conducts business through its wholesale network, which includes correspondents
in 29 states.

            On March 31, 1998, Commonwealth Bank acquired selected assets of
Edmunds Financial Corporation d/b/a Service First Mortgage, a mortgage company
headquartered in Annandale, Virginia. Among the assets acquired from Service
First Mortgage was its production branch located in Annandale, Virginia. Under
the terms of the transaction, the group will operate under the ComNet Mortgage
Services name.

            YEAR 2000. Commonwealth is primarily dependent on its suppliers of
computer services to become Year 2000 compliant. Commonwealth is monitoring its
computer services provider, as well as its third party system vendors, to ensure
that the Company's systems continue to meet its internal needs and those of its
customers. As a result of Commonwealth's arrangement with these vendors, the
Company does not expect material expenditures to be incurred to address the Year
2000 issue.

FINANCIAL CONDITION

            GENERAL. Total assets increased by $99.7 million, or 4%, from $2.3
billion at December 31, 1997, to $2.4 billion at June 30, 1998. The increase was
primarily the result of increases in loans receivable and mortgage loans held
for sale. These increases were offset, in part, by a decrease in mortgage-backed
securities and investment securities. Total liabilities increased by $114.7
million, or 6%, from $2.1 billion at December 31, 1997, to $2.2 billion at June
30, 1998. This increase was the result of increases in notes payable and other
borrowings, deposits, accrued interest payable, accrued expenses and other
liabilities, and advances from borrowers for taxes and insurance. Shareholders'
equity as of June 30, 1998, equaled $199.8 million, compared to $214.9 million
at December 31, 1997. This $15.1 million, or 7%, decrease was primarily the
result of the $19.3 million purchase of $0.8 million shares of treasury stock,
offset, in part, by a $2.9 million, or 2%, increase in earnings retention during
the first six months of 1998.

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

            CASH, INTEREST-BEARING DEPOSITS, AND SHORT-TERM INVESTMENTS ("CASH
AND CASH EQUIVALENTS"). Cash and cash equivalents increased by $6.3 million, or
12%, from $53.9 million at December 31, 1997, to $60.2 million at June 30, 1998.

            MORTGAGE LOANS HELD FOR SALE. Mortgage loans held for sale increased
by $36.4 million, or 97%, from $37.6 million at December 31, 1997, to $74.0
million at June 30, 1998. The increase was primarily attributable to an increase
in loans originated during June 1998.

            INVESTMENT SECURITIES. Investment securities decreased by $13.4
million, or 26%, from $51.3 million at December 31, 1997 to $37.9 million at
June 30, 1998. The decrease was primarily attributable to the maturity of U.S.
Treasury and U.S. Government agency securities, the recording of a valuation

            MORTGAGE-BACKED SECURITIES. Mortgage-backed securities decreased by
$26.3 million, or 4%, from $735.3 million at December 31, 1997 to $709.0 million
at June 30, 1998. The decrease in mortgage-backed securities during the first
six months of 1998 was related to repayments and prepayments and the $30 million
call of mortgage-backed securities during the first quarter of 1998. The
decrease was offset, in part, by a strategy to enhance the Company's net
interest income through the purchase of mortgage-backed securities funded
through Federal Home Loan Bank ("FHLB") advances.

            Mortgage-backed securities generally increase the quality of the
Company's assets by virtue of the insurance or guarantees related to the
securities, are more liquid than individual mortgage loans, and may be used to
collateralize borrowings or other obligations of the Company. At June 30, 1998
and December 31, 1997, $406.8 million, or 57%, and $479.4 million, or 65%,
respectively, of the Company's mortgage-backed securities were insured or
guaranteed by the Government National Mortgage Association ("GNMA"), the Federal
Home Loan Mortgage Corporation ("FHLMC"), or the Federal National Mortgage
Association ("FNMA"). As part of its investment policy, the Company also has the
ability to invest in private mortgage-backed securities. These non-federally
insured mortgage-backed securities, which are generally rated AA or better,
yield a higher rate of return and involve a higher risk of loss than comparable
mortgage-backed securities issued by the GNMA, FHLMC, or the FNMA, and serve to
further diversity the Company's mortgage-backed securities portfolio. At June
30, 1998 and December 31, 1997, $302.2 million, or 43%, and $255.9 million, or
35%, respectively, of the Company's mortgage-backed securities were private
mortgage-backed securities. The following table sets forth the Company's
mortgage-backed securities portfolio at the dates indicated.

            mortgage loans had adjustable interest rates.
(2)         Consists entirely of loans (or securities backed by loans) which are
            guaranteed by the U.S. Government, with the majority adjusting
            monthly or quarterly. All such loans or securities were purchased by
            the Company.

            Total mortgage loans originated and purchased for the six months
ended June 30, 1998, increased by $294.5 million, or 109%, from $270.2 million
for the six months ended June 30, 1997 to $564.7 million for the six months
ended June 30, 1998. The $294.5 million increase in mortgage originations was
the result of increases in retail and wholesale residential mortgage
originations. Closed loans relating to Commonwealth's retail network totaled
$363.4 million during the six months ended June 30, 1998, an increase of 104%
compared to $178.1 million for the six months ended June 30, 1997.
Commonwealth's Wholesale Lending Department originates loans through a network
of correspondent brokers in 29 states. All loans are underwritten using the same
criteria as those used for retail originations. Closed loans relating to
Commonwealth's wholesale network totaled $201.3 million during the six months
ended June 30, 1998, an increase of 119% compared to $92.1 million for the six
months ended June 30, 1997.

                       AND RESULTS OF OPERATIONS-CONTINUED

            Consumer loans increased by $25.7 million, or 13%, from $194.8
million at December 31, 1997, to $220.5 million at June 30, 1998. At June 30,
1998, consumer loans represented 16% of the Company's loan portfolio and were
comprised of $37.4 million of equity lines of credit, $116.8 million of second
mortgage loans, $31.0 million of recreational vehicle loans, and $35.4 million
of other consumer loans. At December 31, 1997, consumer loans represented 15% of
total loans and were comprised of $41.6 million of equity lines of credit, $98.9
million of second mortgage loans, $22.2 million of recreational vehicle loans,
and $32.1 million of other consumer loans.

            As of June 30, 1998, commercial loans, exclusive of loans guaranteed
by the Small Business Administration ("SBA"), totaled $108.3 million, or 8%, of
the Company's total loan portfolio, as compared to $96.0 million, or 8%, at
December 31, 1997. At June 30, 1998, commercial loans (other than SBA loans)
were comprised of $78.4 million of commercial real estate loans and $30.0
million of business loans. At December 31, 1997, commercial loans (other than
SBA loans) were comprised of $71.5 million of commercial real estate loans and
$24.5 million of business loans. Commercial loans are generally considered to
have a greater risk than residential mortgage loans because the risk of borrower
default is greater, and the collateral is more likely to decline in value and
may be more difficult to liquidate than single-family residences.

            NONPERFORMING ASSETS. The Company's nonperforming assets, which
principally consist of nonaccrual loans and real estate acquired through
foreclosure, increased by $0.1 million, or 2%, from $9.6 million at December 31,
1997, to $9.7 million at June 30, 1998. At June 30, 1998, the Company's $9.7
million of nonperforming assets amounted to 0.41% of total assets. At December
31, 1997, the Company's $9.6 million of nonperforming assets amounted to 0.42%
of total assets. The following table sets forth information relating to the
Company's nonperforming assets at the dates indicated.

            ALLOWANCE FOR LOAN LOSSES. The Company's allowance for loan losses
amounted to $9.5 million at June 30, 1998, compared to $9.0 million at December
31, 1997. It is management's policy to maintain an allowance for estimated loan
losses based upon an assessment of prior loss experience, the volume and type of
lending conducted by the Company, industry standards, past due loans, general
economic conditions, and other factors related to the collectability of the loan
portfolio. At June 30, 1998, the Company's allowance for loan losses amounted to
110% of total nonperforming loans and 0.70% of total loans held for investment,
as compared to 101% of total nonperforming loans and 0.71% of total loans held
for investment at December 31, 1997. The Company utilizes these percentages as
only one of the factors in assessing the adequacy of the allowance for loan
losses at various points in time. The following table sets forth the activity in
the Company's allowance for loan losses during the periods indicated.

            DEPOSITS. Deposits increased by $26.2 million, or 2%, to $1.6
billion at June 30, 1998, primarily related to increases in business and
supermarket deposits, as well as increases in principal and interest escrows
established pursuant to loan servicing agreements. These increases were offset,
in part, by a decrease in traditional branch deposits.

            BORROWINGS. The Company's borrowings consist principally of advances
from the FHLB and securities sold under agreements to repurchase. FHLB advances
increased by $95.0 million, or 45%, to $308.0 million at June 30, 1998, from
$213.0 million at December 31, 1997. Repurchase agreements decreased by $33.4
million, or 14%, to $212.7 million at June 30, 1998, from $246.1 million at
December 31, 1997. The Company's borrowings are used to fund lending and
investment activities, withdrawals from deposit accounts, and other
disbursements which occur in the normal course of business. Dependent upon the
funding requirements and interest rate risk considerations, these borrowings are
hedged with off-balance-sheet financial instruments.

            ACCRUED INTEREST PAYABLE, ACCRUED EXPENSES AND OTHER LIABILITIES
("OTHER LIABILITIES"). Other liabilities increased by $13.9 million, or 78%, to
$31.7 million at June 30, 1998, from $17.7 million at December 31, 1997,
primarily related to an increase in accrued interest payable.

results and/or the comparability of such results with the second quarter of
1997, including:

            - A $1.9 million (after-tax) downward valuation adjustment in the
              second quarter of 1998 relating to an equity investment in a
              mortgage servicing partnership;

            - A $0.5 million (after-tax) one-time charge in the second quarter
              of 1998 relating to a policy change in accounting for compensation
              expense, including commissions on mortgage originations;

            - A $0.5 million (after-tax) net gain on sale of securities in the
              second quarter of 1998, compared to a $0.1 million (after-tax)
              net loss in the second quarter of 1997;

            - A $0.3 million (after-tax) reversal of the Bank's pension
              liability during the second quarter of 1997; and 

            - A $0.3 million (after-tax) reversal of a liability relating
              to a contract with the Company's data processing  provider during
              the second quarter of 1997.

            For the six months ended June 30, 1998, net income was $5.3 million,
or $0.34 per common share on a diluted basis, compared to $8.4 million, or $0.51
per common share, for the six months ended June 30, 1997. In addition to the
factors affecting the comparison of second quarter results, the decrease in net
income for the six months of 1998, compared to the first six months of 1997, was
also attributable to a $1.0 million (after-tax) nonrecurring net gain in the
first quarter of 1997 relating to the sale of the Company's previous
headquarters building and a branch property; a $0.4 million (after-tax) reversal
of a deferred tax liability in the first quarter of 1998; and a $0.1 million
(after-tax) refund of prior year FDIC premiums received in the first quarter of
1997.

            NET INTEREST INCOME. Net interest income was $17.7 million in the
second quarter of 1998, a decrease of 1% compared to $17.9 million in the second
quarter of 1997. For the first six months of 1998, net interest income decreased
by 2%, to $35.2 million, versus $35.8 million for the comparable period in 1997.
The decreases were primarily attributable to a lower net interest margin,
offset, in part, by an increase in average interest-earning assets.

            Average interest-earning assets totaled $2.2 billion for both the
second quarter and six months ended June 30, 1998. This compared to $2.1 billion
for both the second quarter and six months ended June 30, 1997. The increases in
interest-earning assets were due primarily to increases in the Company's loan
portfolio. Compared to the second quarter of 1997, average mortgage loans
increased 16% to $984.5 million, average consumer loans increased 23% to $213.7
million, and average commercial loans increased 18% to $121.3 million in the
second quarter of 1998. Average loans represented 84% of average deposits in the
second quarter of 1998, compared to 74% in the second quarter of 1997. Relative
to the first six months of 1997, average mortgage loans increased 14% to $965.3
million, average consumer loans increased 20% to $206.1 million, and average
commercial loans increased 18% to $118.9 million for the six months of 1998.
Average loans represented 82% of average deposits for the first six months of
1998, compared to 74% for the first six months of 1997.

            The net interest margin was 3.15% in the second quarter of 1998,
compared to 3.41% in the second quarter of 1997. The decrease was primarily
attributable to a 0.19% reduction in the yield on interest-earning assets and a
0.04% increase in the cost of interest-bearing liabilities.

            For the six months ended June 30, 1998, the net interest margin was
3.24%, versus 3.49% in the comparable 1997 period. The decrease was primarily
attributable to a 0.14% reduction in the yield on interest-earning assets and a
0.08% increase in the cost of interest-bearing liabilities. The decrease in the
yield on interest-earning assets for the second quarter and first six months of
1998, relative to the comparable periods in 1997, was primarily attributable to
lower market interest rates. The increase in the cost of interest-bearing
liabilities for the second quarter and first six months of 1998, relative to the
comparable periods in 1997, was primarily attributable to competitive pressures
on the cost of certificates of deposit.

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

            PROVISION FOR LOAN LOSSES. Provision for loan losses totaled $1.0
million and $1.5 million in the second quarter and six months ended June 30,
1998, respectively. The provision for loan losses totaled $0.3 million and $0.6
million in the second quarter and six months ended June 30, 1997, respectively.
At June 30, 1998, the allowance for credit losses totaled $9.5 million, or 0.70%
of loans, compared to $9.8 million, or 0.82%, at June 30, 1997, and $9.0
million, or 0.71%, at December 31, 1997.

            NONINTEREST INCOME. Noninterest income totaled $7.4 million in the
second quarter of 1998, compared to $4.0 million in the second quarter of 1997.
The increase reflected a $1.8 million increase in the net gain on sale of
mortgage loans and a $0.9 million increase in the net gain on the sale of
securities. The increase in the net gain on sale of mortgage loans was
attributable to sharply higher mortgage origination volume, which totaled $270.5
million in the second quarter of 1998, versus $172.0 million in the second
quarter of 1997. Also contributing to the increase in noninterest income in the
second quarter of 1998 was a $0.5 million increase in deposit fees and a $0.3
million increase in other noninterest income. The increase in deposit fees was
primarily attributable to growth in supermarket banking, expansion of
Commonwealth's commercial banking activities, and increased ATM fees. The
increase in other noninterest income was primarily attributable to earnings from
an investment in an insurance product.

            Noninterest income was $13.4 million for the first six months of
1998, compared to $9.3 million for the same 1997 period. The increase reflected
a $3.2 million increase in the net gain on sale of mortgage loans and a $1.0
million increase in deposit fees. The increase in the net gain on sale of
mortgage loans was attributable to sharply higher mortgage origination volume,
which totaled $564.7 million for the first six months of 1998, versus $270.2
million for the first six months of 1997. The increase in deposit fees was
primarily attributable to the same factors responsible for the increase in the
second quarter of 1998. Also contributing to the increase in noninterest income
for the first six months of 1998 was a $0.9 million increase in the net gain on
the sale of securities, earnings of $0.4 million from an investment in an
insurance product, and a $0.4 million reversal of a deferred tax liability.
These increases were partially offset by the effect of a $1.5 million net gain
on the sale of the Company's previous headquarters building and the sale of a
branch property in the first half of 1997, and a $0.3 million decrease in
servicing fees in the first half of 1998.

            NONINTEREST EXPENSE. Noninterest expense was $21.8 million in the
second quarter of 1998, compared to $16.1 million in the second quarter of 1997.
The increase was primarily attributable to a $2.7 million valuation adjustment
in the second quarter of 1998 relating to an equity investment in a mortgage
servicing partnership which is experiencing significant prepayments in its
mortgage servicing portfolio. Also reflected in the increase in noninterest
expense in the second quarter of 1998 was a $0.8 million one-time charge related
to a policy change in accounting for compensation expense, including commissions
on mortgage originations given the substantial increase in volumes. The increase
in noninterest expense was also due to the $0.4 million reversal of the Bank's
pension liability, and the $0.4 million reversal of a liability relating to a
contract with the Company's data processing provider during the second quarter
of 1997. In addition to the above items, the increase was attributable to higher
commission expenses relating to growth in mortgage originations, as well as an
increase in expenses relating to supermarket banking, commercial banking, and
certain benefit plans.

            Noninterest expense was $39.2 million for the six months ended June
30, 1998, compared to $31.8 million for the same period in 1997. The increase
was primarily attributable to the same factors responsible for the increase in
the second quarter of 1998, as well as a $0.2 million refund of prior year FDIC
premiums received in the first quarter of 1997. Partially offsetting these
increases was a $0.3 million decrease in the amortization of intangible assets.

            PROVISION FOR INCOME TAXES. Provision for income taxes was $0.8
million, or 34% of income before income taxes in the second quarter of 1998,
compared to $1.8 million, or 33%, in the second quarter of 1997. For the first
six months of 1998, provision for income taxes was $2.6 million, or 32% of
income before income taxes, compared to $4.3 million, or 34%, in the first six
months of 1997. The decrease in the income tax rate for the first six months of
1998 was primarily attributable to low income housing tax credits and the
reversal of a deferred tax valuation allowance.
