                               LSB FINANCIAL CORP.
                          NOTES TO FINANCIAL STATEMENTS
                                 MARCH 31, 1997

Note 1 - General

The financial statements were prepared in accordance with the instructions for
Form 10-QSB and, therefore, do not include all of the disclosures necessary for
a complete presentation of financial position, results of operations and cash
flows in conformity with generally accepted accounting principles. Except for
the adoption of required accounting changes, these interim financial statements
have been prepared on a basis consistent with the annual financial statements
and include, in the opinion of management, all adjustments, consisting of only
normal recurring adjustments, necessary for a fair presentation of the results
of operations and financial position for and at the end of such interim periods.

Note 2 - Principles of Consolidation

The accompanying financial statements include the accounts of LSB Financial
Corp. (the Company), its wholly owned subsidiary Lafayette Savings Bank, FSB
(the Bank) and the Bank's wholly owned subsidiary, LSB Service Corporation. All
significant intercompany transactions have been eliminated upon consolidation.

Note 3 - Earnings per share

Earnings per share are computed based upon the weighted average number of shares
outstanding during the period. Unearned ESOP shares are not considered to be
outstanding for the earnings per share computation. The following table presents
share data used to compute earnings per share.

                                                       Quarter ended

Shares used to compute
    earnings per share                              900,166       929,774

The options outstanding at March 31, 1997 were not dilutive.

Note 4 - Accounting Changes

Effective January 1, 1997, the Company adopted Financial Accounting Standard No.
125, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishment of Liabilities." This standard revises the accounting for
transfers of financial assets, such as loans and securities, and for
distinguishing between sales and secured borrowings. It is effective for some
transactions in 1997 and others in 1998. Management does not expect the effect
on LSB's financial position and results of operations to be significant.

               MANAGEMENT'S DISCUSSION OF RECENT OPERATING RESULTS

Forward Looking Statements

         Certain statements in this report that relate to LSB Financial Corp.'s
plans, objectives or future performance may be deemed to be forward-looking
statements within the meaning of the Private Securities Litigation Act of 1995.
Such statements are based on Management's current expectations. Actual
strategies and results in future periods may differ materially from those
currently expected because of various risks and uncertainties. Additional
discussion of factors affecting LSB Financial's business and prospects is
contained in the Company's periodic filings with the Securities and Exchange
Commission.

Financial Condition

         Comparison of Financial Condition at March 31, 1997 and December 31,
1996.

         Total assets increased $3.4 million during the three months from
December 31, 1996 to March 31, 1997. This increase was primarily due to a $7.5
million increase in the Company's loan portfolio offset by a $5.3 million
decrease in the Company's loans held for sale as the Company continued its
efforts to restructure its balance sheet by increasing the size of its
higher-yielding multi-family, land and land development, construction,
commercial real estate and commercial business loan and consumer loan
portfolios. A $9.5 million increase in deposits was used to fund loan growth and
to decrease borrowings from the Federal Home Loan Bank by $6.5 million.
Non-performing loans remained at $2.5 million at December 31, 1996 and at March
31, 1997, consisting of $2.3 million of purchased equipment leases and two
single family residences. Shareholders' equity increased from $16.8 million at
December 31, 1996 to $17.1 million at March 31, 1997, an increase of $272,000
primarily due to $358,000 in net income partially offset by the repurchase of an
additional $55,000 of the Company's stock as part of an ongoing 5.00% stock
buy-back program and by a $73,000 cash dividend to shareholders.

Results of Operations

Comparison of Operating Results for the Three Months Ended March 31, 1996 and
March 31, 1997.

         General. Net income for the three months ended March 31, 1997 was
$358,000, an increase of $15,000 or 4.37% from net income of $343,000 for the
three months ended March 31, 1996. This increase was primarily due to a $121,000
increase in net interest income and a $45,000 increase in non- interest income
in the first quarter of 1997, offset by a $24,000 provision for loan losses and
a $107,000 increase in operating expenses.

         Net Interest Income. Net interest income for the three months ended
March 31, 1997 increased $121,000, or 8.53% over the same period in 1996. This
increase was primarily attributable to the success of management's continuing
efforts to restructure the Company's balance sheet by

investing funds in higher-yielding loans, particularly commercial real estate
and consumer loans from the lower yielding securities portfolio. The Company's
net interest margin (net interest income divided by average interest-earning
assets) decreased from 3.73% for the three months ended March 31, 1996 to 3.56%
for the three months ended March 31, 1997. The decline in yield was offset by
increased volume as average interest-earning assets increased from $152.1
million for the first quarter of 1996 to $172.7 million for the first quarter of
1997.

         Interest income on loans increased $435,000 or 15.01% for the three
months ended March 31, 1997 compared to the same three months in 1996, primarily
the result of an increase of $22.1 million in average loans outstanding. This
increase was primarily due to an active residential real estate market in 1996
due to continued relatively low interest rates and a strong local economy, and
the ongoing success of the Company's focus on higher-yielding multi-family, land
and land development, construction, commercial real estate and commercial
business loan and consumer loan production. These higher-yielding portfolios
increased from $62.2 million at December 31, 1996 to $65.6 million at March 31,
1997. This increase in volume was partially offset by a decrease in the average
yield on loans from 8.47% for the first three months of 1996 to 8.39% for the
first three months of 1997, caused primarily by the increasing competitiveness
of the local loan origination market. Both the net interest margin and the
average yield on loans in 1997 were negatively impacted by the placement of the
Bennett Funding leases on non-accrual status effective April 1, 1996. Management
estimates that interest lost during the first quarter of 1997 from those leases
was approximately $57,000.

         Interest earned on securities, money market investments and FHLB stock
decreased $19,000 for the three months ended March 31, 1997 compared to the same
three months in 1996. This was the result of an overall $1.5 million decrease in
average investments offset by a slight increase in the average yield from 5.92%
to 6.01% over the same period.

         Interest expense for the three months ended March 31, 1997 increased
$295,000 over the same period in 1996. This increase was primarily due to an
increase of $24.5 million in average interest-bearing liabilities, consisting of
an additional $11.4 million in the average balance of customer deposit accounts
and a $13.1 million increase in the average balance of Federal Home Loan Bank
advances drawn to fund loan demand The average rate paid on interest bearing
liabilities remained at 4.83% for both the first quarter of 1996 and the first
quarter of 1997.

         Provision for Loan Losses. The Company establishes its provision for
loan losses based on a systematic analysis of risk factors in the loan
portfolio. The analysis includes evaluation of concentration of credit, past
loss experience, current economic conditions, the amount and composition of the
loan portfolio, estimated fair value of the underlying collateral, loan
commitments outstanding , delinquencies, industry standards and using the
services of a consultant to assist in the evaluation of its growing commercial
loan portfolio. Management's analysis results in the allocations of allowance
amounts for each loan type. Based on this analysis, during the year ended
December 31, 1996 the Company recorded an $800,000 provision for loan losses
primarily in response to the situation involving Bennett Funding Group (Bennett)
of Syracuse, New York through which the Company owns $2.4 million of equipment
leases. On March 29, 1996, the Securities and Exchange Commission filed civil
and criminal complaints against an officer of

Bennett and shortly thereafter, Bennett sought Chapter 11 bankruptcy protection.
The Bank has been paid interest through March 31, 1996. Based upon the
bankruptcy filing and the uncertainty about when principal and interest payments
might resume, the leases were placed on non-accrual status as of April 1, 1996
and the Bank has allocated $970,000 of its $1.7 million allowance for loan
losses to these receivables. The Bank's $2.4 million investment is comprised of
numerous small dollar equipment leases. While management believes that the Bank
holds original lease documents, the complaint alleges various fraudulent actions
including allegations that Bennett may have sold the same leases to two or more
buyers. To date management has not been notified of duplication of any leases it
owns. Management is currently evaluating settlement offers and believes that its
reserve allocation will be sufficient to cover any losses. In addition, the
Company provided an additional $24,000 provision for loan losses during the
first quarter of 1997. In addition to the Bennett leases there were $131,000 of
non-performing loans at March 31, 1997, consisting of two single family
residences, one of which has been sold and is awaiting a scheduled closing. The
allowance for loan losses to total loans was 1.08% at December 31, 1996 and
1.06% at March 31, 1997. Non-performing loans totaled $2.5 million at December
31, 1996, representing 1.35% of total assets, and $2.5 million at March 31,
1997, representing 1.34% of total assets.

         Non-Interest Income. Non-interest income for the three months ended
March 31, 1997 increased by $45,000, or 29.22%, over the same period in 1996.
This was primarily due to a $10,000 increase in service charges and fees on
deposit accounts due to the increasing number of these accounts, and a $36,000
increase in the gain on the sale of mortgage loans in the secondary market. The
increase in the gain on the sale of loans resulted from the increased sales
activity and the absence of a market value adjustment at March 31, 1997. On
March 31, 1996, the Company held $964,000 of fixed rate mortgage loans in its
held for sale portfolio. The required adjustment to mark these loans to market
was ($23,000). There was no comparable adjustment needed at March 31, 1997.

         Non-Interest Expense. Non-interest expense for the three months ended
March 31, 1997 increased $107,000 over the same period in 1996. The major
components of this increase included a $68,000 increase in salaries and employee
benefits and a $34,000 increase in occupancy and equipment expense. The increase
in salaries and employee benefits, and occupancy and equipment expenses were
incurred in connection with the opening of the Company's fourth branch.

                  Income Tax Expense. The Company's income tax provision
increased by $20,000 for the quarter ended March 31, 1997 compared to the
quarter ended March 31, 1996. This was primarily due to the increase in income
before income taxes.

         Liquidity. Liquidity management is both a daily and long-term function
for the Bank's senior management. The Bank adjusts its investment strategy,
within the limits established by the investment policy, based upon assessments
of expected loan demand, expected cash flows, FHLB advance opportunities, market
yields and objectives of its asset/liability management program. Base levels of
liquidity have generally been invested in interest-earning overnight and time
deposits with the FHLB of Indianapolis. Funds for which a demand is not foreseen
in the near future are invested in investment and other securities for the
purpose of yield enhancement and asset/liability management.

         The Bank is required to maintain minimum levels of liquidity as defined
by regulatory agencies. The liquidity requirement, which can vary, is based upon
a percentage of deposits and short term borrowings and is currently 5.0%. The
Bank's internal policy for liquidity is approximately 8%. The Company's
liquidity ratios at December 31, 1996 and March 31, 1997 were 7.31% and 8.09%,
respectively.

         Capital Resources. Shareholders' equity totaled $17.1 million at March
31, 1997 compared to $16.8 million at December 31, 1996, an increase of $272,000
or 1.62%, primarily due to an increase in net income of $358,000 partially
offset by a stock repurchase of $55,000 and the Company's first cash dividend of
$73,000. Federal regulations require the Bank to maintain certain minimum levels
of regulatory capital. The regulations currently require tangible capital as
defined by regulation to be at least 1.5% of total assets, as also defined by
regulation, that core capital as defined be 3.0% of total assets, and that risk
based capital be at least 8.0% of risk-based assets as defined by regulations.
At March 31, 1997 the Bank's capital ratios were as follows:

                                           Amount         Percent of
                                            (000)      applicable assets
