                         PITTSBURGH HOME FINANCIAL CORP.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Basis of Presentation

        The accompanying unaudited consolidated financial statements of
        Pittsburgh Home Financial Corp. (the "Company") have been prepared in
        accordance with instructions to Form 10-Q. Accordingly, they do not
        include all of the information and footnotes required by generally
        accepted accounting principles for complete financial statements.
        However, such information reflects all adjustments (consisting solely of
        normal recurring adjustments) which are, in the opinion of management,
        necessary for a fair statement of results for the interim periods.

        The results of operations for the three months ended December 31, 1997
        are not necessarily indicative of the results to be expected for the
        year ending September 30, 1998. The unaudited consolidated financial
        statements and notes thereto should be read in conjunction with the
        audited financial statements and notes thereto for the year ended
        September 30, 1997.


Note 2 - Business

        The Company's subsidiary, Pittsburgh Home Savings Bank (the "Bank"), is
        a state chartered stock savings bank primarily engaged in attracting
        retail deposits from the general public and using such deposits to
        originate loans (primarily single-family residential loans.) The Bank
        conducts business from eight offices in Allegheny and Butler counties of
        western Pennsylvania and primarily lends in this geographic area. The
        Bank is subject to competition from other financial institutions and
        other companies which provide financial services. The Bank is subject to
        the regulations of certain federal and state agencies and undergoes
        periodic examinations by those regulatory authorities.

Note 3 - Principles of consolidation

        The consolidated financial statements include the accounts of Pittsburgh
        Home Financial Corp. and its wholly owned subsidiary, Pittsburgh Home
        Savings Bank. All significant intercompany balances and transactions
        have been eliminated in consolidation.

Note 4 - Conversion

        The Company is a Pennsylvania corporation which is the holding company
        for the Bank. The Company was organized by the Bank for the purpose of
        acquiring all of the capital stock of the Bank in connection with its
        conversion from a mutual stock organization to the stock holding company
        form which was completed on April 1, 1996 (the "Conversion").

        In the Conversion, 2,182,125 shares of common stock were sold at a
        subscription price of $10.00 per share, resulting in net proceeds of
        approximately $21.0 million. In exchange for 50% of the net conversion
        proceeds ($10.5 million), the Company acquired 100% of the stock of the
        Bank and retained the remaining $10.5 million at the holding company
        level.


Note 5 - Earnings per share

        Earnings per share are based on the weighted average number of shares of
        common stock. In 1997, the Financial Accounting Standards Board ("FASB")
        issued Statement No. 128, "Earnings per Share". Statement 128 replaced
        the calculation of primary and fully diluted earnings per share with
        basic and diluted earnings per share. Unlike primary earnings per share,
        basic earnings per share excludes any dilutive effects of options and
        unvested stock grants. Diluted earnings per share is very similar to the
        previously reported fully diluted earnings per share. Earnings per share
        amounts for all periods have been presented, and where appropriate,
        restated to conform to the Statement 128 requirements.

</TABLE>


        In accordance with Statement 128, unreleased shares held by the Employee
        Stock Ownership Plan (ESOP) (148,073 and 161,477 shares at December 31,
        1997 and 1996 respectively) and unvested shares held for the Recognition
        and Retention Plan (RRP) (73,293 and 87,285 shares at December 31, 1997
        and 1996, respectively) have been excluded from basic average shares
        outstanding. Such shares are included in basic average shares
        outstanding as they are released for allocation (ESOP) or become vested
        (RRP). Unvested RRP shares and stock options are included in diluted
        average shares outstanding based upon the treasury stock method.

Note 6 - Return of Capital

        On December 19, 1997, the Company paid a special one-time cash
        distribution of $2.50 per share. The Company obtained a private letter
        ruling from the Internal Revenue Service which allowed them to treat
        $2.43 per share of this distribution as a return of capital. The return
        of capital was reflected as a reduction to additional paid-in-capital in
        the Company's financial statements. For the stockholders, the return of
        capital is treated as a reduction in the cost basis of the shares and is
        not subject to income taxes until the



                                       9
<PAGE>   10

        shares are sold.  The  remaining  $.07 per share was treated as an 
        ordinary  dividend. The total distribution paid was $4,923,423 on 
        1,969,369 shares of stock.


Note 7 - Employee Stock Ownership Plan (ESOP)

        In connection with the Conversion, the Company established an ESOP for
        the benefit of eligible employees. The ESOP Trust borrowed $1.9 million
        from the Company and purchased 174,570 shares, equal to 8% of the total
        number of shares issued in the Conversion. The Company accounts for its
        ESOP in accordance with SOP 93-6, "Employers Accounting for Employee
        Stock Ownership Plans," which requires the Company to recognize
        compensation expense equal to the fair value of the ESOP shares during
        the periods in which they become committed to be released. To the extent
        that the fair value of ESOP shares differs from the cost of such shares,
        this differential will be charged or credited to equity. Management
        expects the recorded amount of expense to fluctuate as continuing
        adjustments are made to reflect changes in the fair value of the ESOP
        shares. Employers with internally leveraged ESOPs, such as the Company,
        will not report the loan receivable from the ESOP as an asset and will
        not report the ESOP debt from the employer as a liability.

Note 8 - Stock Option Plan

        On October 15, 1996, the Stock Option Plan was approved by the
        Company's stockholders. A total of 218,212 shares of common stock may
        be issued pursuant to the Stock Option Plan and 195,511 shares were
        awarded as of December 31, 1997. These options are subject to vesting
        provisions as well as other provisions of the Stock Option Plan. No
        options have been exercised through December 31, 1997.

Note 9 - Recognition and Retention Plan and Trust (RRP)

        On October 15, 1996, the RRP was approved by the Company's stockholders.
        A total of 87,285 shares of common stock are available for awards
        pursuant to the RRP and 67,960 shares were awarded as of December 31,
        1997. Awards will vest in equal installments over a five year period,
        with the first installment vesting on the first anniversary date of the
        grant and each additional installment vesting on the four subsequent
        anniversaries of such date, subject to various requirements as more
        fully described in the plan documents. Compensation cost related to RRP
        shares earned during the three month periods ended December 31, 1997 and
        1996 was $53,160 and $35,440, respectively.

        The Company has purchased on the open market shares of common stock to
        fully fund the RRP. The cost of unearned RRP shares is recorded as a
        reduction of stockholders' equity.

Note 10 - Recent Accounting and Regulatory Developments

        The Financial Accounting Standards Board released Statement of Financial
        Accounting Standard Number 125, "Accounting for Transfers and Servicing
        of Financial Assets and Extinguishments of Liabilities" ("SFAS 125") in
        June 1996. SFAS 125 is effective for transfers and servicing of
        financial assets and extinguishments of liabilities occurring after
        December 31, 1996 and is to be applied prospectively. SFAS 125
        establishes standards for resolving issues related to the circumstances
        under which the transfer of financial assets should be considered as
        sales of all or part of the assets or as secured borrowings and about
        when a liability should be considered extinguished. The Company does not
        anticipate any material impact on statements of income and financial
        condition from the adoption of this statement.

Note 11 - Subsequent Event

        In January 1998, the Company formed a trust subsidiary, Pittsburgh Home
        Capital Trust I ("the Trust"), and on January 30, 1998, the Trust sold
        $11.5 million of 8.56% Cumulative Trust Preferred Securities to the
        public. The Preferred Securities represent undivided beneficial
        interests in the Trust. The Trust used the proceeds from the sale of the
        preferred securities to purchase junior subordinated deferrable interest
        debentures which were used by the Company. The Company will use the
        proceeds for general corporate purposes. The subordinated debentures are
        redeemable at anytime after January 30, 2003 by the Company. The
        subordinated debentures will mature on January 30, 2028.

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

FINANCIAL CONDITION

        At December 31, 1997, the Company's total assets amounted to $299.7
million compared with $273.3 million at September 30, 1997, an increase of 9.7%.
Cash and interest-bearing deposits increased $883,000, or 16.9%, to $6.1 million
at December 31, 1997, compared to $5.2 million at September 30, 1997. Investment
securities trading increased $1.3 million, or 137.9% from $956,000 at September
30, 1997 to $2.3 million at December 31, 1997. During fiscal 1997, the Company
implemented a wholesale leveraging strategy designed to take advantage of its
excess capital. The Company determined to invest in mortgage-backed securities
and U.S. government and agency obligations, at a positive interest rate spread
over the funding obligation, which has been Federal Home Loan Bank ("FHLB")
advances. Investments and mortgage-backed securities (held to maturity and
available for sale) increased by $13.7 million, or 18.4%, from $74.4 million at
September 30, 1997. During the quarter ended December 31, 1997, the Company
purchased $17.3 million in investments and mortgage-backed securities. Loans
receivable, net of allowance, increased $8.9 million, or 4.9%, to $190.3 million
at December 31, 1997 compared to $181.3 million at September 30, 1997. The
growth is primarily attributable to increases in residential mortgage loans.

        Total liabilities increased by $30.5 million, or 12.5%, to $275.0
million at December 31, 1997 compared to $244.5 million at September 30, 1997.
Deposits increased by $3.2 million, or 2.3% to $141.9 million at December 31,
1997 compared to $138.7 million at September 30, 1997. The increase in deposits
is attributable, in part, to the Bank's new supermarket branch located in the
Pittsburgh area. Borrowed funds increased $25.8 million or 25.4% to $127.5
million at December 31, 1997 compared to $101.7 million at September 30, 1997,
as the Company increased its FHLB advances to increase liquidity and used those
funds to reinvest in assets at higher yields.

        Total stockholders' equity decreased $4.1 million or 14.2% to $24.7
million at December 31, 1997 compared to $28.8 million at September 30, 1997.
The decrease was primarily attributable to a special return of capital dividend
totaling $4.9 million that the Company paid on December 19, 1997, which was
partially offset by net income during the period.


                                       12

RESULTS OF OPERATIONS

        GENERAL. The Company reported net income of $571,000 and $443,000 for
the three months ended December 31, 1997 and 1996, respectively. Basic and
diluted earnings per share were $.33 and $.31 per share for the quarter ended
December 31, 1997, compared to $.22 and $.22 per share, respectively, for the
same quarter of 1996. Trading activity gains had an after tax impact on both
calculations of $.05 per share for the quarter ended December 31, 1997. In
addition to the increased net income in 1997, the per share results were
favorably impacted by an overall reduction in the average number of shares
outstanding as a result of stock repurchase programs in effect from November
1996 through April 1997. This $128,000, or 28.9%, increase was primarily the
result of an increase in net interest income after the provision for losses on
loans of $159,000 or 10.1% and an increase in total noninterest income of
$217,000 or 196.8% primarily due to the gains on trading account securities
which were partially offset by an increase in the provision for loan losses of
$45,000 or 60.0%, an increase in total noninterest expense of $198,000 or 19.9%,
and an increase in the provision for income taxes of $50,000 or 20.4%.

        INTEREST INCOME. Interest income increased $1.4 million or 35.9% for the
three months ended December 31, 1997, compared to the same period in 1996. The
increase was due to the increase in investment and loan origination activity.
The average balance of investment and mortgage-backed securities totaled $83.1
million and had a weighted average yield of 7.4% compared to $52.1 million with
a weighted average yield of 6.3% for the same period in 1996. The increase in
investments is attributable to the Company's wholesale leveraging strategy. The
investment and mortgage-backed securities purchased have been funded primarily
with advances from the FHLB. The average balance on loans receivable increased
by $43.6 million, which was partially offset by a 26 basis point decline in the
average yield earned thereon.

        INTEREST EXPENSE. Interest expense increased $1.2 million or 52.2% for
the three months ended December 31, 1997, compared to the same period in 1996.
The increase was due primarily to a $80.5 million increase in average
interest-bearing liabilities. Average deposits increased $12.4 million for the
three months ended December 31, 1997 when compared to the same period in 1996.
Average borrowed funds increased $68.1 million for the three month period ended
December 31, 1997 when compared to the same period in 1996. Such increases were
primarily due to the opening of a new branch, as well as, increased borrowings
from the FHLB of Pittsburgh.

        PROVISION FOR LOAN LOSSES. During the three months ended December 31,
1997, the Company recorded provisions for losses on loans of $120,000 compared 
to $75,000 for the comparable period in 1996. Subsequent to September 30, 1997, 
the Company's non-performing assets have continued to increase. From 
September 30, 1997 to December 31, 1997, the Company's non-performing assets 
increased from $4.6 million to $5.0 million. This $400,000 or 8.7% increase was
primarily attributable to two new non-accruing residentia construction loans.
The Company has increased its originations of single-family loans during the
past several 


                                       13
<PAGE>   14

years, which management attributes to be the primary reason for increased
non-performing assets. Management does not attribute the increase to any
specific weakness within the Company or in the marketplace generally. Although
management utilizes its best judgment in providing for losses with respect to
its non-performing assets, there can be no assurance that the Company will be
able to dispose of such non-performing assets without establishing additional
provisions for losses on loans or further reductions in the carrying value of
its real estate owned.

        NONINTEREST INCOME. Noninterest income increased by $217,000 or 196.8%
for the three months ended December 31, 1997, compared to the three months ended
December 31, 1996. In April 1997, the Board authorized a trading account whereby
up to $2.5 million could be invested in trading account securities, with not
more than $1.0 million in any single issue, to be accounted for as trading
securities in accordance with SFAS No. 115. Under Board authorization, there is
no limit on the types of securities that the Company may invest in provided that
the securities are approved under the Company's investment policy, although to
date the Company has limited its investments to equity securities of financial
institutions. At December 31, 1997, the Company had an aggregate of $2.3 million
invested in 11 securities. During the three months ended December 31, 1997, the
Company recognized a pre-tax net gain on trading account securities of $130,000.
Non-interest income (excluding the trading gains) increased $87,000 or 78.6%.

        NONINTEREST EXPENSES. Noninterest expenses increased by $198,000 or
19.9% for the three months ended December 31, 1997, compared to the same period
in 1996. The increase was primarily attributable to an $157,000 increase in
salaries and employee benefits, a $26,000 increase in net occupancy expense, and
a $7,000 increase in other operating expenses (consisting primarily of office
supplies, legal and professional fees). The increase in salaries and employee
benefits is due to normal salary increases and the hiring of new employees. The
increase in net occupancy expense is the result of the addition of a new branch.

        PROVISION FOR INCOME TAXES. The Bank incurred provisions for income
taxes of $292,000 during the three months ended December 31, 1997, compared with
$242,000 for the same period in 1996. The effective tax rates during the three
months ended December 31, 1997 and 1996 were 33.8% and 35.8%, respectively.

LIQUIDITY AND CAPITAL RESOURCES

        The Company's primary sources of funds are deposits, repayments,
prepayments and maturities of outstanding loans, maturities of investment
securities and other short-term investments, and funds provided from operations.
While scheduled loan repayments and maturing investment securities and
short-term investments are relatively predictable sources of funds, deposit
flows and loan prepayments are greatly influenced by the movement of interest
rates in general, economic conditions and competition. The Company manages the
pricing of its deposits to maintain a deposit balance deemed appropriate and
desirable. In addition, the


                                       14
<PAGE>   15

Company invests in short-term investment securities and interest-earning assets
which provide liquidity to meet lending requirements. Although the Company's
deposits have historically represented the majority of its total liabilities,
the Company also utilizes other borrowing sources, primarily advances from the
FHLB of Pittsburgh. At December 31, 1997, the Company had $127.5 million of
outstanding advances from the FHLB of Pittsburgh.

        Liquidity management is both a daily and long-term function of business
management. The Bank uses its sources of funds primarily to meet its ongoing
commitments, to pay maturing savings certificates and savings withdrawals, to
fund loan commitments and to maintain a portfolio of mortgage-backed and
investment securities. At December 31, 1997, the total approved loan commitments
outstanding amounted to $10.8 million, and unused lines of credit amounted to
$698,000. Certificates of deposit scheduled to mature in one year or less at
December 31, 1997, totaled $62.7 million. Management believes that a significant
portion of maturing deposits will remain with the Bank.

        As of December 31, 1997, the Bank's regulatory capital was well in
excess of all applicable regulatory requirements. At December 31, 1997, the
Bank's Tier 1 risk-based, total risk-based and Tier 1 leverage capital ratios
amounted to 17.69%, 16.66% and 7.83%, respectively, compared to regulatory
requirements of 4.0%, 8.0% and 4.0%, respectively.

                                       15

IMPACT OF YEAR 2000.

        Some of the Company's older computer programs including those used by
certain third party providers, were written using two digits rather than four to
define the applicable year. As a result, those computer programs have
time-sensitive software that recognize a date using "00" as the year 1900 rather
than the year 2000. This could cause a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, send invoices, or engage in similar normal business
activities.

The Company is currently performing an assessment and may have to modify or
replace portions of its software so that its computer systems will function
properly with respect to dates in the year 2000 and thereafter. The total Year
2000 project cost is estimated to have an immaterial impact. The project is
estimated to be completed not later than December 31, 1998, which is prior to
any anticipated impact on its operating system. The Company believes that with
modifications to existing software and conversions to new software, the Year
2000 Issue will not pose significant operational problems for its computer
systems or those of the third party providers. However, if such modifications
and conversions are not made, or are not completed timely, the Year 2000 Issue
could have a material impact on the operations of the Company.

The Company has initiated communications with all of its significant suppliers
and large customers to determine the extent to which the Company's interface
systems are vulnerable to those third parties' failure to remediate their own
Year 2000 Issues. There is no guarantee that the systems of other companies on
which the Company's systems rely will be timely converted and would not have an
adverse effect on the Company's systems.

The cost of the project and the date on which the Company believes it will
complete the Year 2000 modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events, including
the continued availability of certain resources and other factors. However,
there can be no guarantee that these estimates will be achieved and actual
results could differ materially from those anticipated. Specific factors that
might cause such material differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant computer codes, and similar uncertainties.

           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Quantitative and qualitative disclosures about market risk are presented
at September 30, 1997 in Item 7A of the Company's Annual Report on Form 10-K,
filed with the SEC on December 24, 1997. Management believes there have been no
material changes in the Company's market risk since September 30, 1997.
