                            FOUNDATION BANCORP, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           For the three months ended
                           September 30, 1999 and 1998


1. BASIS OF PRESENTATION
   ---------------------

         The accompanying unaudited consolidated financial statements were
prepared in accordance with instructions for Form 10-QSB and, therefore, do not
include information or footnotes necessary for a complete presentation of
consolidated financial position, results of operations and cash flows in
conformity with generally accepted accounting principles. However, in the
opinion of management, all adjustments (consisting only of normal recurring
accruals) which are necessary for a fair presentation of the consolidated
financial statements have been included. The results of operations for the three
months ended September 30, 1999 and 1998, are not necessarily indicative of the
results which may be expected for an entire fiscal year.


2. PRINCIPLES OF CONSOLIDATION
   ---------------------------

         The accompanying consolidated financial statements include the accounts
of the Foundation Bancorp, Inc. ("the Company") and its wholly-owned subsidiary,
Foundation Savings Bank ("Foundation"). All significant intercompany items have
been eliminated.


3. EARNINGS PER SHARE
   ------------------

         Basic earnings per share for the three month periods ended
September 30, 1999 and 1998, were computed based on weighted average shares
outstanding of 435,581 and 437,420, respectively, which gives effect to a
reduction for the 19,660 and 25,453 unallocated shares held by the Foundation
Bancorp, Inc. Employee Stock Ownership Plan (the "ESOP") at such dates,
respectively, in accordance with Statement of Position 93-6 ("SOP 93-6") issued
by the American Institute of Certified Public Accountants.


4. EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS
   -------------------------------------------

         In March 1998, the FASB issued SFAS No. 128, "Earnings Per Share,"
which is effective for periods ending after December 15, 1998, including interim
periods. SFAS No. 128 simplifies the calculation of earnings per share ("EPS")
by replacing primary EPS with basic EPS. It also requires dual presentation of
basic EPS and diluted EPS for entities with complex capital structures. Basic
EPS includes no dilution and is computed by dividing income available to common
shareholders by the weighted-average common shares outstanding for the period.
Diluted EPS reflects the potential dilution of securities that could share in
earnings such as stock options, warrants or other common stock equivalents. All
prior period EPS data must be restated to conform with the new presentation.

<PAGE>   7

         In February 1998, the FASB issued SFAS No. 129, "Disclosures of
Information about Capital Structure." SFAS No. 129 consolidates existing
accounting guidance relating to disclosure about a company's capital structure.
Public companies generally have always been required to make disclosures now
required by SFAS No. 129 and, therefore, SFAS No. 129 should have no impact on
the Company. SFAS No. 129 is effective for financial statements for periods
ending after December 15, 1998.

         In June 1998, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." SFAS No. 130 establishes standards for reporting and display of
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general-purpose financial statements. SFAS No. 130 requires
that all items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements. It does not
require a specific format for that financial statement but requires that an
enterprise display an amount representing total comprehensive income for the
period in that financial statement.

         SFAS No. 130 requires that an enterprise (1) classify items of other
comprehensive income by their nature in a financial statement and (2) display
the accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. SFAS No. 130 is effective for fiscal years beginning after
December 15, 1998. Reclassification of financial statements for earlier periods
provided for comparative purposes is required.

         In June 1998, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information." SFAS No. 131 significantly changes
the way that public business enterprises report information about operating
segments in annual financial statements and requires that those enterprises
report selected information about reportable segments in interim financial
reports issued to shareholders. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
SFAS No. 131 uses a "management approach" to disclose financial and descriptive
information about an enterprise's reportable operating segments which is based
on reporting information the way that management organizes the segments within
the enterprise for making operating decisions and assessing performance. For
many enterprises, the management approach will likely result in more segments
being reported. In addition, SFAS No. 131 requires significantly more
information to be disclosed for each reportable segment than is presently being
reported in annual financial statements and requires that selected information
be reported in interim financial statements. SFAS No. 131 is effective for
financial statements for periods beginning after December 15, 1998. Because the
Company has no non-banking subsidiaries, SFAS No. 131 will not affect the
Company.

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

DISCUSSION OF FINANCIAL CONDITION CHANGES FROM JUNE 30, 1999 TO SEPTEMBER 30,
-----------------------------------------------------------------------------
1999
----

         At September 30, 1999, the Company's assets totaled $33.0 million, a
decrease of $0.7 million, or 2.2%, from the $33.7 million total at June 30,
1999. Cash and equivalents were $0.3 million at September 30, 1999, a decrease
of $2.1 million, or 85.4%, over the $2.4 million at June 30, 1999. Investments
in certificates of deposit decreased $0.3 million, or 25.2%, as maturing funds
were not reinvested, and mortgage-backed securities decreased $0.3 million, or
6.2%, resulting from repayments. The cash flow from these changes funded an
increase in loans receivable of $0.4 million, or 2.0%, as Foundation changed its
emphasis to portfolio lending rather than sales of loans with the increase in
market rates, and an increase in investment securities of $1.5 million, or
39.9%, as Foundation sought higher returns in the current interest rate
environment.

         The decrease in cash and equivalents partially funded a decrease in
deposits of $0.6 million, or 2.3%, as longer term deposits were not renewed.
Advances from the Federal Home Loan Bank decreased $20,300, or 3.4%, as a result
of scheduled repayments. Advances from borrowers for taxes, insurance and other
increased $83,967, or 141.0%, resulting from timing differences in the payment
of real estate taxes. Shareholders' equity decreased $158,279, or 2.2%, as a
result of the $.50 per share dividend which totaled $231,437 paid to
shareholders in September 1999.

         The Office of Thrift Supervision has two minimum regulatory capital
standards for savings associations. At September 30, 1999, Foundation's capital
substantially exceeded each of the requirements. The following is a summary of
Foundation's approximate regulatory capital position, in dollars and as a
percentage of regulatory assets, at September 30, 1999:

interest income after provision for loan losses of $27,038, or 11.4%, which was
partially offset by a decrease in other income of $11,539, or 46.1%, an increase
in general, administrative and other expense of $9,442, or 4.8%, and an increase
in federal income taxes of $2,944, or 12.9%


Net Interest Income
-------------------

         Net interest income after provision for losses on loans for the three
months ended September 30, 1999, increased $27,038, or 11.4%, compared to the
same period of 1998. A decrease in total interest income of $36,563, or 5.8%,
was excluded by a decrease in total interest expense of $60,601, or 15.4%.
Interest income on loans decreased $27,962, or 6.4%, the result of a decrease in
loans receivable of $0.6 million and a 27 basis points decline in the yield
since September 30, 1998, as borrowers refinanced for lower interest rates.
Interest on mortgage-backed securities increased $4,011, or 6.1%, due to higher
yields. Interest on investment securities increased $33,629, or 54.0%, due to
higher yields on a larger portfolio. Interest on interest-bearing deposits
decreased $46,241, or 65.8%, due to a decline in average deposits as funds were
reinvested in higher yielding mortgage loans and investment securities. Interest
expense on deposits decreased $60,677, or 15.8%, due to a lower weighted average
rate on a smaller portfolio.


Other Operating Income
----------------------

         Other operating income for the three months ended September 30, 1999
decreased $11,539, or 46.1%, compared to the same period of 1998 due to the
absence of loan sales during the first quarter of 1999.


General, Administrative and Other Expense
-----------------------------------------

         General, administrative and other expense for the three months ended
September 30, 1999 increased $9,442, or 4.8%, compared to the same period of
1998. This was primarily due to the increase in occupancy and equipment of
$1,118, or 5.7%, the result of the purchase of new Y2K compliant computer
equipment and software, and an increase in employee compensation and benefits of
$9,098, or 8.2%. The employee compensation and benefit expense increase resulted
from the amortization of the expense of the Recognition and Retention Plan and a
lower adjustment to compensation for the accounting treatment of deferred loan
fees due to fewer loan closings. Federal income taxes increased $2,944, or
12.9%, due to higher earnings.


DISCUSSION OF YEAR 2000 ISSUES
------------------------------

         As with most providers of financial services, Foundation's operations
are heavily dependent on information technology systems. Foundation has
addressed the potential problems associated with the possibility that the
computers that control or operate Foundation's information technology system and
infrastructure may not be programmed to read four-digit date codes and, upon
arrival of the year 2000, may recognize the two-digit code "00" as the year
1900, causing systems to fail to function or to generate erroneous data.

         The Company's primary data processing applications are handled by a
third-party service bureau which has transferred to a fully year 2000-compliant
processing system which has been fully tested.

         The Company has not identified any additional material expenses that
are likely to be incurred by Foundation in connection with this issue. No
assurance can be given, however, that additional expense will not be incurred in
future periods, which could adversely affect the Company's net earnings and
financial condition.

         In addition to possible expense related to its own systems, the Company
could incur losses if year 2000 issues adversely affect Foundation's depositors
or borrowers. Such problems could include delayed loan payments due to year 2000
problems affecting any significant borrowers or impairing the payroll systems of
large employers in Foundation's primary market area. Because Foundation's loan
portfolio is highly diversified with regard to individual borrowers and types of
businesses and Foundation's primary market area is not significantly dependent
upon one employer or industry, Foundation does not expect any significant or
prolonged difficulties that will affect net earnings or cash flow.
