                         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 consolidated financial statements include the accounts of Pittsburgh
        Home Financial Corp. and its wholly owned subsidiaries, Pittsburgh Home
        Savings Bank (the "Bank") and Pittsburgh Home Capital Trust I. All
        significant intercompany balances and transactions have been eliminated
        in consolidation.

        As of January 1, 1998, the Company adopted Statement Number 130,
        "Reporting Comprehensive Income." Statement 130 establishes new rules
        for the reporting and display of comprehensive income and its
        components; however, the adoption of this Statement had no impact on the
        Company's net income or shareholders' equity. Statement 130 requires
        unrealized gains or losses on the Company's available-for-sale
        securities, which prior to adoption were reported separately in
        stockholders' equity to be included in other comprehensive income. Prior
        year financial statements have been reclassified to conform to the
        requirements of Statement Number 130.

        During the three months ended December 31, 1998 and 1997, total
        comprehensive income (loss) amounted to a loss of $218,933 and income of
        $778,183, respectively.

        The results of operations for the three months ended December 31, 1998
        are not necessarily indicative of the results to be expected for the
        year ending September 30, 1999. 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, 1998.


Note 2 - Business
         --------

        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 



                                        7

<PAGE>   8

        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.

        The Company's trust subsidiary, Pittsburgh Home Capital Trust I (the
        "Trust") was formed to issue $11.5 million of 8.56% Cumulative Trust
        Preferred Securities. These securities represent undivided beneficial
        interests in Pittsburgh Home Capital Trust I. The Trust purchased junior
        subordinated deferrable interest debentures which were issued by the
        Company.



Note 3 - Earnings per share
         ------------------

        Earnings per share are based on the weighted average number of shares of
        common stock. Basic earnings per share is calculated by dividing income
        available to holders of common shares by the weighted average number of
        common shares outstanding during the period. Options, warrants, and
        other potentially diluted securities are excluded from the basic
        calculation, but are included in diluted earnings per share.

The following table sets forth the computation of basic and diluted earnings per
share:

        The Company accounts for its Employee Stock Ownership Plan (ESOP) in
        accordance with SOP 93-6, "Employers Accounting for Employee Stock
        Ownership Plans,"; shares controlled by the ESOP are not considered in
        the weighted average shares outstanding until the shares are committed
        for allocation to an employee's individual account. In accordance with
        SOP 93-6, uncommitted shares held by the ESOP (154,190 and 148,075
        shares at December 31, 1998 and 1997 respectively) are excluded from
        basic average shares outstanding.

Note 4 - 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 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 5 - Recent Accounting and Regulatory Developments
         ---------------------------------------------

        The Financial Accounting Standards Board issued Statement No. 131,
        "Disclosures about Segments of an Enterprise and Related
        Information "which is effective for fiscal years beginning after 
        December 15, 1997 and requires public companies to disclose certain
        information about reporting operating segments in complete sets of the
        financial statements of the enterprise. Statement No. 131 does not
        materially effect the Company's financial position or results of
        operations as the Company's management views the Bank as one segment of
        business which is community banking.

        Financial Accounting Standards Board Statement No. 132, "Employers
        Disclosures about Pensions and Other Post-retirement Benefits" is
        effective for fiscal years beginning after December 15, 1997. This
        statement requires revised disclosures about pension and other
        post-retirement benefit plans, but does not impact the measurement of
        recognition of those plans. Statement No. 132 had no impact on the
        Company's financial position or results of operations.

Note 6 - Capital Trust I
         ---------------

        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 and
        received proceeds of $10,769,829 (net of $735,171 of offering costs).
        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 issued by the Company. 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, 1998, the Company's total assets amounted to $386.5
million compared with $374.3 million at September 30, 1998, an increase of 3.2%.
Cash and interest-bearing deposits increased $1.9 million, or 42.8%, to $6.4
million at December 31, 1998, compared to $4.5 million at September 30, 1998.
Investment securities trading decreased $1.2 million, or 85.3% from $1.4 million
at September 30, 1998 to $208,000 at December 31, 1998; subsequent to September
30, 1998, the Company discontinued its trading securities strategy. Investments
and mortgage-backed securities (held-to-maturity and available for sale)
decreased by $3.4 million, or 2.4%, from $140.2 million at September 30, 1998 to
$136.8 million at December 31, 1998. During the quarter ended December 31, 1998,
the Company increased its loan originations. Loans receivable, net of allowance,
increased $13.6 million, or 6.4%, to $225.6 million at December 31, 1998
compared to $212.0 million at September 30, 1998. The growth is primarily
attributable to increases in residential mortgage loans.

        Total liabilities increased by $12.9 million, or 3.7%, to $362.4 million
at December 31, 1998 compared to $349.5 million at September 30, 1998. Deposits
increased by $3.2 million, or 2.1% to $157.2 million at December 31, 1998
compared to $154.0 million at September 30, 1998. Borrowed funds increased $8.2
million or 5.3% to $163.5 million at December 31, 1998 compared to $155.3
million at September 30, 1998, as the Company increased its FHLB advances to aid
liquidity and fund loans receivable.

        Total stockholders' equity decreased $700,000 or 2.8% to $24.1 million
at December 31, 1998 compared to $24.8 million at September 30, 1998. The
decrease was primarily attributable to the purchase of treasury stock and a loss
in other comprehensive income.

sales. For the quarter ended December 31, 1998, the $73,000, or 12.8% decrease
in net income is primarily attributable to a decrease in noninterest income of
$188,000 or 57.4%, an increase in noninterest expense of $76,000 or 6.4%, and an
increase in the provision for loan losses of $30,000 or 25.0%, which were
partially offset by an increase in net interest income before the provision for
loan losses of $153,000 or 8.3% and a decrease in income tax expense of $68,000
or 23.3%. The Company recognized pre-tax net losses on trading activities and
investment sales of $70,000 for the quarter ended December 31, 1998 as compared
to pre-tax gains of $130,000 for the quarter ended December 31, 1997. Excluding
the results of the trading activities and investment sales, net income for the
quarter ended December 31, 1998 was $546,000 as compared to $485,000 for the
same quarter in 1997, an increase of 12.6%.

        INTEREST INCOME. Interest income increased $1.4 million or 26.4% for the
three months ended December 31, 1998, compared to the same period in 1997. The
increase was due to the increase in investment and loan origination activity.
The average balance of investment and mortgage-backed securities totaled $145.1
million and had a weighted average yield of 6.83% for the three months ended
December 31, 1998 compared to $83.1 million with a weighted average yield of
7.39% for the same period in 1997. The average balance on loans receivable
increased by $31.5 million, which was partially offset by a 22 basis point
decline in the average yield earned thereon.

        INTEREST EXPENSE. Interest expense increased $1.3 million or 36.7% for
the three months ended December 31, 1998, compared to the same period in 1997.
The increase was due primarily to a $93.7 million increase in average
interest-bearing liabilities. Average deposits increased $15.5 million for the
three months ended December 31, 1998 when compared to the same period in 1997.
Average borrowed funds increased $69.6 million for the three month period ended
December 31, 1998 when compared to the same period in 1997. Interest expense
associated with the guaranteed preferred beneficial interest in subordinated
debt totaled $255,000 for the three months ended December 31, 1998. On March 6,
1998, the Bank purchased a $25.0 million notional value interest rate cap from
the FHLB. This purchase was in connection with the Bank's ongoing management of
its interest rate risk position. The cap is being used as an off-balance sheet
hedge to the Bank's risk associated with shorter term liabilities. The cost of
the cap is being amortized as a yield adjustment to interest expense over the
five year term of the transaction. Interest expense associated with the
amortization of the rate cap totaled $12,500 for the three months ended December
31, 1998.

         PROVISION FOR LOAN LOSSES. It is management's policy to maintain an
allowance for estimated losses based on the perceived risk of loss in the loan
portfolio and the adequacy of the allowance. Management's periodic evaluation of
the adequacy of the allowance is based on the Company's past loan loss
experience, known and inherent risks in the portfolio, adverse situations that
may affect the borrower's ability to repay, the estimated value of the
underlying collateral and current economic conditions. The allowance for loan
losses is evaluated based on an assessment of the losses inherent in the loan
portfolio. Management classifies all delinquent assets as Special Mention,
Substandard, Doubtful or Loss. The evaluation of the adequacy of the allowance
incorporates an estimated range of required allowance based on the items noted
above. A reserve level is estimated by management for each category of
classified loans, with an estimated percentage applied to the delinquent loan
category balance. In addition, management notes that there is an inherent risk
of potential loan loss in the Company's overall, non-classified loan portfolio.
This inherent risk is addressed by applying an estimated low and high percentage
of potential loss to the remaining unclassified loan portfolio. Management
extends out the various line item balances and estimated percentages in order to
arrive at an estimated required loan loss allowance reserve. Activity for the
period under analysis is taken into account (charge offs, recoveries, provision)
in order to challenge the Company's overall process, as well as its previous
loss history. The estimated range of required reserve balance is then compared
to the current allowance for loan loss balance, and any required adjustments are
made accordingly.

Assets classified as a Loss are considered uncollectible and of such little
value that continuance as an asset is not warranted. A Loss classification does
not mean that an asset has no recovery or salvage value, but that it is not
practical or desirable to defer writing off all or a portion of the asset, even
though partial recovery may be affected in the future. All loans classified as
loss have been written off through provision in specific allowance reserve. The
allowance is increased by provisions for loan losses which are charged against
income. During the three months ended December 31, 1998, the Company recorded
provisions for losses on loans of $150,000 compared to $120,000 for the
comparable period in 1997.

The Company designates all loans that are 90 or more days past due as
non-performing. Generally, when loans are classified as non-performing, unpaid
accrued interest is a reduction of interest income on loans receivable and is
only recognized when cash payments are received. Subsequent to September 30,
1998, the Company's non-performing assets have continued to increase. From
September 30, 1998 to December 31, 1998, the Company's non-performing assets
increased from $4.5 million to $5.8 million. This $1.3 million or 28.9% increase
was primarily attributable to four new non-accruing construction loans (which
had principal balances ranging from $132,000 to $288,000). Three of such loans,
with an aggregate outstanding balance of $664,000 were made to one contractor.
Two of the homes are completed and listed for sale, while the other property
will not be developed until the other two properties are sold. The fourth spec
construction loan was sold in December 1998 for $288,000 which equaled the
Bank's carrying value.



                                       13

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 decreased by $188,000 or 57.4%
for the three months ended December 31, 1998, compared to the three months ended
December 31, 1997. The decrease is attributable to a pre-tax net loss on trading
activities and investment sales of $70,000 which were offset by an increase in
other income and fees of $13,000 or 6.6%. The Company recognized pre-tax net
gains of $130,000 for the comparable period in 1997.

        NONINTEREST EXPENSES. Noninterest expenses increased by $76,000 or 6.4%
for the three months ended December 31, 1998, compared to the same period in
1997. The increase was primarily attributable to a $33,000 increase in salaries
and employee benefits, a $22,000 increase in data processing costs, a $15,000
increase in the loss on sale of foreclosed real estate, $12,000 increase in net
occupancy expense. The increase in salaries and employee benefits is due to
normal salary increases and the hiring of new employees. The increase in data
processing costs is the result of upgrading the Company's technology.

        PROVISION FOR INCOME TAXES. The Bank incurred provisions for income
taxes of $224,000 during the three months ended December 31, 1998, compared with
$292,000 for the same period in 1997. The effective tax rates during the three
months ended December 31, 1998 and 1997 were 31.0% and 33.8%, respectively.


LIQUIDITY AND CAPITAL RESOURCES

        The Company's primary sources of funds are deposits, advances from the
FHLB, 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 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, 1998,
the Company had $163.5 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 

                                       14

<PAGE>   15


savings certificates and savings withdrawals, to fund loan commitments and to
maintain a portfolio of mortgage-backed and investment securities. At December
31, 1998, the total approved loan commitments outstanding amounted to $14.5
million, and unused lines of credit amounted to $2.7 million. Certificates of
deposit scheduled to mature in one year or less at December 31, 1998, totaled
$64.1 million. Management believes that a significant portion of maturing
deposits will remain with the Bank.

        As of December 31, 1998, the Bank's regulatory capital was well in
excess of all applicable regulatory requirements. At December 31, 1998, the
Bank's Tier 1 risk-based, total risk-based and Tier 1 leverage capital ratios
amounted to 18.77%, 17.80% and 8.15%, respectively, compared to regulatory
requirements of 4.0%, 8.0% and 4.0%, respectively.

YEAR 2000

        The Year 2000 (Y2K) issue is primarily a result of computer software
programs recognizing a two digit date field rather than the full four digits
which identify the appropriate year. Any computer program or hardware that is
date sensitive may recognize "00" as year 1900 as opposed to the intended year
2000. The Y2K problem started decades ago when early computers had very limited
memory and storage space.

        The objective of managing the Year 2000 process is for the institution
to determine the scope of the problem and to focus its efforts and attention on
solving it. The Federal Financial Institution's Examination Council ("FFIEC")
outlined the Year 2000 management process as a five phase procedure [(1)
Awareness (2) Assessment (3) Renovation (4) Validation (5)



                                       15

<PAGE>   16


Implementation] that each financial institution would have to navigate in
identifying and fixing its Year 2000 exposures. The Company has developed a
detailed timetable which identifies various milestones and deadlines to aid in
managing the Year 2000 process.

        The Company outsources substantially all of its data processing
functions, and it is working very closely with its third party provider and
other vendors within the Bank's project plan to ensure that its operational and
financial systems will not be adversely affected by the Y2K problem.

        The Awareness and Assessment phases of the Company's plan are completed
and related to the understanding and educating of the Board and appropriate
management personnel as to the issues related to the Y2K problem. The Company is
continuously upgrading its comprehensive project plan (year 2000 binder), and
has completed its inventory of equipment, hardware, and software; updated its
Disaster Recovery Plan ("DRP"); and reported the project status to its Board,
its regulators, and its customer base. The Awareness phase, including the
comprehensive inventory of all hardware and software systems (including systems
purchased from software vendors) was completed March 31, 1998. The Assessment of
all hardware and software systems was completed June 30, 1998.

        The Renovation phase of the Bank's project plan centered around the
initial contact and response evaluation of year 2000 letters and worksheets
which were sent to vendors and suppliers; the focus was on entities which have
been classified as fatal or critical to the ongoing operations of the Company.
The Company is coordinating with its third party vendors and suppliers to
complete their Y2K testing.

        The Validation and Implementation phases revolve around the resolution
of all vendor's and supplier's compliance status. All critical equipment or
services that are non-compliant will be replaced by the appropriate milestone
date. The Company's testing and implementation of internal mission-critical
systems is ongoing and has an expected completion date of March 31, 1999. The
testing of vendor provided mission-critical systems, including the Company's
third party service provider is in process and ongoing with an expected
completion date of June 30, 1999. The Company and the third party service
provider successfully completed its first round of online testing in September
1998. The second test is currently scheduled for March 1999.

        The Company has contacted its loan and deposit customers that may
present some exposure to Y2K compliance. Commercial loan customers that are not
Y2K compliant may present some risk of default. The Company's initial assessment
of its commercial loan and other customer accounts present an immaterial impact
on the Company's statement of operations. Continued monitoring and evaluation of
this risk is incorporated into the Company's Y2K project plan.

        The Company's costs associated with Year 2000 include an additional
assessment from its third party provider, consultant fees associated with its
DRP and the ongoing Y2K project plan, various hard costs for the replacement of
non-compliant computer, telephone, and related equipment. Excluding the "soft"
costs of Company management and personnel time, the Company estimates that the
total Year 2000 project costs will not exceed $200,000 (pre-tax). As 



                                       16

<PAGE>   17

of December 31, 1998, the Company estimates that it has incurred less than
$70,000 in connection with its Y2K project plan.

        In the event that the Company and its service providers face a "worst
case" year 2K scenario and its systems would not handle the date changeover, the
impact on the Company is at this point uncertain. Clearly, the Company's Y2K
contingency plan would be enacted, which would include off-line, manual postings
of all transactions, as well as addressing any required Company service provider
changes or outsourcing to Y2K compliant entities.

        The Company's plans to complete Y2K compliance are based on management's
and the Board's best estimates. There can be no guarantee that these estimates
will be achieved, and ending results could be significantly different due to
unforeseen circumstances.


           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Quantitative and qualitative disclosures about market risk are presented
at September 30, 1998 in Item 7A of the Company's Annual Report on Form 10-K,
filed with the SEC on December 23, 1998. Management believes there have been no
material changes in the Company's market risk since September 30, 1998.
