                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                            For the Nine months ended

                             March 31, 2000 and 1999

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 nine
months ended March 31, 2000 and 1999, 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 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 nine month periods ended March 31,
2000 and 1999, were computed based on weighted average shares outstanding of
440,991 and 436,611, respectively, which gives effect to a reduction for the
14,140 and 19,651 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.

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

DISCUSSION OF FINANCIAL CONDITION CHANGES FROM JUNE 30, 1999 TO MARCH 31, 2000
------------------------------------------------------------------------------

         At March 31, 2000, the Company's assets totaled $33.1 million, a
decrease of $0.7 million, or 1.9%, from the $33.8 million total at June 30,
1999. Cash and equivalents decreased $1.4 million, or 56.8%, certificates of
deposit decreased $0.8 million, or 67.0%, and mortgage-backed securities
decreased $0.6 million, or 11.1%, from their respective totals at June 30, 1999.
These changes funded a decrease in deposits of $0.5 million, or 1.9%, an
increase in loans receivable of $0.6 million and an increase in investment
securities of $1.5 million as the Company sought higher yields in alternative
investments.

         Advances from the Federal Home Loan Bank decreased $61,735, or 10.3%,
from scheduled repayments. Advances from borrowers for taxes, insurance and
other increased $84,964, or 142.7%, resulting from timing differences in the
payment of real estate taxes. Other liabilities decreased $130,854, or 65.6%,
due to timing differences in the payment of accounts payable. Shareholders'
equity decreased $37,473, or 0.5%, the result of the $.50 per share annual
dividend, which totaled $231,438, paid to shareholders in September 1999.

         The Office of Thrift Supervision has two minimum regulatory capital
standards for savings associations. At March 31, 2000, 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 March 31, 2000:

1999
----

General
-------

     The Company recorded net earnings of $101,140 for the nine months ended
March 31, 2000, a decrease of $40,098, or 28.4%, from the net earnings of
$141,238 recorded for the nine months ended March 31, 1999. The decrease was the
result of an increase in net interest income after provision for loan losses of
$75,965, or 10.8%, and lower federal income taxes of $17,227, or 21.9%, offset
by an increase in general, administrative and other expense of $63,036, or
10.6%, and a decrease in other income of $70,254, or 62.7%.

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

     Net interest income after the provision for losses on loans for the nine
months ended March 31, 2000, increased $75,965, or 10.8%, compared to the same
period of 1999. A decrease in total interest income of $43,153, or 2.4%, was
more than offset by a decrease in total interest expense of

$110,118, or 9.9%. The decrease in total interest income resulted from a
decrease in interest earned on loans of $31,375, or 2.5%, resulting from a lower
yield on the weighted average portfolio. Interest on mortgage-backed securities
decreased $15,269, or 6.8%, resulting from a lower portfolio balance. Interest
on interest-bearing deposits decreased $181,235, or 74.4%, resulting from lower
portfolio balances. These decreases were partially offset by an increase in
interest income on investment securities of $184,726, or 175.9%, resulting from
a larger portfolio balance. The decrease in total interest expense was primarily
attributable to the decrease in interest expense on deposits of $109,549, or
10.1%, due to a smaller portfolio, which more than offset the effect of a higher
weighted average rate.

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

     Other operating income totaled $41,718 for the nine months ended March 31,
2000, a decrease of $70,254, or 62.7%, compared to the same period in 1999, due
to a substantial decrease in gains on sales of loans as lending volume declined
resulting from the reduced refinancing activity as interest rates increased and
higher yielding loans are being kept for the Company's portfolio.

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

     General, administrative and other expense for the nine months ended March
31, 2000 increased $63,036, or 10.6%, compared to the same period of 1999. This
was primarily due to the increase in other expense of $46,374, or 45.8%, the
result of approximately $55,000 in professional fees incurred in connection with
the evaluation and negotiation of corporate opportunities which the Company
subsequently concluded did not warrant further consideration. Occupancy and
equipment expense increased $3,300, or 5.5%, resulting from increased
depreciation on the new Y2K compliant computer system, and employee compensation
and benefits increased $16,897, or 5.0%, resulting from the amortization of the
Foundation Savings Bank Recognition and Retention Plan and Trust Agreement (the
"RRP") shares and the Financial Accounting Standards Board ("FASB") accrual
based on fewer loan originations. Federal income taxes decreased $17,227, or
21.9%, due to lower net income before taxes.

General
-------

     The Company recorded net earnings of $14,040 for the three months ended
March 31, 2000, a decrease of $27,143, or 65.9%, from the net earnings of
$41,183 recorded for the three months ended March 31, 1999. The decrease was
primarily the result of an increase in net interest income after provision for
loan losses of $25,027, or 10.6%, and lower federal income taxes of $13.074, or
55.9%, which were substantially offset by a decrease in other income of $15,331,
or 56.0%, and an increase in general, administrative and other expense of
$49,913, or 25.1%.

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

     Net interest income after provision for losses on loans for the three

increase in total interest income of $18,900, or 3.3%, offset by a decrease in
total interest expense of $3,127, or 0.9%. Interest income on loans increased
$15,360, or 3.9%, the result of an increase in the loan portfolio. Interest on
investment securities increased $82,418, or 569.1%, as excess liquidity was
invested in higher yielding federal agency notes. These increases were partially
offset by decreases in interest on mortgage-backed securities of $8,635, or
11.0%, and interest on interest-bearing deposits of $70,243, or 75.5%, both the
result of lower outstanding portfolio balances. Interest expense on deposits
decreased $2,026, or 0.6%, due to a higher weighted average rate on a smaller
portfolio.

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

     Other operating income for the three months ended March 31, 2000 decreased
$15,331, or 56.0%, compared to the same period of 1999, due to a substantial
decrease in gains on sales of loans as lending volume declined resulting from
increased interest rates and the higher yielding loans were kept for the
Company's portfolio.

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

     General, administrative and other expense for the three months ended March
31, 2000 increased $49,913, or 25.1%, compared to the same period of 1999. This
was primarily the result of an increase in other expense of $47,372, or 140.1%,
the result of approximately $55,000 in professional fees incurred in connection
with the corporate opportunities discussed previously. Employee compensation and
benefits increased $4,148, or 3.7%, the result of the FASB adjustment on lower
loan production and the amortization of the RRP expenses. Federal deposit
insurance premiums decreased $2,774, or 67.5%, as the level of premiums charged
decreased. Federal income taxes decreased $13,074, or 55.9% due to lower net
income before taxes.
