                    SHELBY COUNTY BANCORP AND SUBSIDIARY
                  NOTES TO CONSOLIDATED FIANCIAL STATEMENTS
                                 (Unaudited)

Note 1   Basis of Presentation

The consolidated financial statements include the accounts of Shelby County
Bancorp (the "Corporation") and its subsidiary Shelby County Savings Bank, FSB
(the "Bank").  A summary of significant accounting policies is set forth in
Note 1 of  Notes to Consolidated Financial Statements included in the September
30, 1997 Annual Report to Shareholders.

The consolidated interim financial statements have been prepared in accordance
with instructions to Form 10-Q, and therefore do not include all information
and footnotes necessary for a fair presentation of financial position, results
of operations and cash flows in conformity with generally accepted accounting
principles.

The consolidated interim financial statements at March 31, 1998 and for the
three months and six months ended March 31, 1998 and 1997 have not been audited
by independent accountants, but reflect, in the opinion of management, all
adjustments (which include only normal recurring adjustments) necessary to
present fairly the financial position, results of operations and cash flows for
such periods.

Note 2   Proposed Acquisition of Shelby County Bancorp

On February 5, 1998, Shelby County Bancorp and Blue River Bancshares , Inc.
entered into an Agreement of Affiliation and Merger into Blue River Bancshares,
Inc. as amended and restated on March 12, 1998. Under ther terms of the Merger
Agreement, each outstanding share of common stock of the Corporation will be
converted into the right to receive $58 from Blue River Bancshares, Inc. The
merger will be accounted for as a purchase.

Note 3   Earnings per Share

Shelby County Bancorp has implemented Statement of Financial Accounting
Standards 128, "Earnings per Share" (EPS) which is effective for interim and
annual periods ending after December 15, 1997, which requires the presentation
of basic and dilutive earnings per share.  Accordingly, these amounts appear on
the financial statements in this Form 10-Q.  EPS have been computed on the
basis of the weighted average number of common shares outstanding and the
dilutive effect of stock options not exercised during the periods presented
using the treasury stock method.  The weighted average number of shares
outstanding for use in the basic EPS computations was 175,950 for the three
months ended March 31, 1998 and 1997.  The weighted average number of shares
for use in the dilutive EPS computations was 181,282 and 179,605 for the three
months ended March 31, 1998 and 1997, respectively.  The weighted average
number of shares outstanding for use in the basic EPS computations was 175,950
for the six months ended March 31, 1998 and 1997.  The weighted average number
of shares for use in the dilutive EPS computations was 181,282 and 179,605 for
the six months ended March 31, 1998 and 1997, respectively.

Note 3   Stock Option Plan

The Corporation has adopted a stock option plan whereby 17,250 shares of
authorized but unissued common stock were reserved for future issuance upon the
exercise of stock options granted to key employees and directors at an option
price of $10 per share.  Options for 12,075 shares at an option price of $10
per share have been granted under the plan.  Three thousand four hundred and
fifty shares of stock have been issued under the plan as of March 31, 1998.
Options for 1,725 shares at an option price of $18 per share have also been
granted under the plan.  Options for 3,450 shares at an option price of $20
per share have also been granted under the plan.  Through March 31, 1998, 3,450
options

Note 4   Stock Option Plan

The Corporation has adopted a stock option plan whereby 17,250 shres of
authorized but unissued common stock were reserved for future issuance upon the
exercise of stock options granted to key employees and directors. Options for
12,075 shares at an option price of $10 per share have been granted under the
plan. Three thousand four hundred and fifty shares of stock have been issued
under the plan as of March 31, 1998. Options for 1,725 shars at an option price
of $18 per share have also been granted under the plan. Through March 31, 1998,
3,450 option have been exercised, leaving 13,800 unexercised options.

Note 5   Dividends

On March 16, 1998, the Board of Directors declared a quarterly cash dividend of
$.125 per share.  The dividend was paid April 13, 1998 to shareholders of
record as of March  30, 1998.


Note 6   Subsequent Events

On May 6, 1998, the Office of Thrift Supervision advised the Bank that, until
certain corrective actions are undertaken, the Bank should cease all commercial
real estate and commmercial lending. In light of the pending acquisition of the
Bank by Blue River Bancshares, Inc. (which currently is expected to close in
June, although there can be no guarantee that the transaction will close then
or at a later date), the Board of Directors of the Bank has determined to cease
all such lending while the transaction is pending. Management does not expect
that ceasing to make such loans during that interim period will have a material
adverse effect on the net earnings of the Bank.

       Management's Discussion and Analysis of Financial Condition and
                            Results of Operations

     Certain statements throughout this section regarding the Corporation's and
the Bank's financial position, business strategy and plans and objectives of
management for future operations are forward-looking statements rather than
historical or current facts.  When used in this section, words such as
"anticipate," "believe," "estimate," "expect," "intend" and similar
expressions, as they relate to the Corporation and the Bank or their respective
managements, identify forward-looking statements.  Such forward-looking
statements are based on the beliefs of the management of the Corporation and
the Bank as well as assumptions made by and information currently available to
the management of the Corporation and the Bank.  Such statements are inherently
uncertain, and there can be no assurance that the underlying assumptions will
prove to be valid.  Actual results could differ materially from those
contemplated by the forward-looking statements as a result of certain factors,
including but not limited to competitive factors and pricing pressures, changes
in legal and regulatory requirements, technological change, product development
risks and general economic conditions, including, but not limited to, changes
in interest rates, loss of deposits and loans to other savings and financial
institutions, substantial changes in financial markets, substantial changes in
real estate values and the real estate market and unanticipated results in
pending legal proceedings.  Such statements reflect the current view of the
Corporation and the Bank with respect to future events and are subject to these
and other risks, uncertainties and assumptions relating to the operations,
results of operation, growth strategy and liquidity of the Corporation and the
Bank.


(a)  Financial Condition:

     Total assets at March 31, 1998, were $98,465,000, an increase of
$7,856,000 from total assets of $90,609,000 at September 30, 1997.  The most
significant increases in assets were in net loans receivable and interest
bearing deposits.  Total net loans receivable increased from $76,524,000 at
September 30, 1997 to $85,687,000 at March 31, 1998.  Interest bearing deposits
decreased from $1,773,000 at September 30, 1997 to $9,000 at March 31, 1998. 
Mortgage loans increased from $61,634,000 at September 30, 1997 to $69,295,000
at March 31, 1998.  Consumer loans increased from $14,732,000 at September 30,
1997 to $16,570,000 at March 31, 1998.  The increase in mortgage loans is
attributed to a very strong local economy and loan demand.  The two branches
that were opened in 1995 have contributed over $8,143,000 in mortgage and
consumer lending.

     Total deposits at September 30, 1997 of $64,633,000 increased to
$70,497,000 at March 31, 1998.  This increase in deposits is primarily due to 
an increase in certificates of deposit and checking accounts.

SCSB generally places loans on a nonaccrual status when the loans become
contractually past due 90 days or more.  At September 30, 1997, all $416,601 of
nonaccrual loans were residential loans.  For the year ended September 30,
1997, the income that would have been recorded had the non-accrual loans not
been in a non-performing status was approximately $31,359, compared to actual
income recorded of $20,667.  At March 31, 1998, all 672,572 of nonaccrual loans
were residential loans.  For the period ended March 31, 1998, the income that
would have been recorded had the non-accrual loans not been in a non-performing
status was approximately $26,478, compared to actual income recorded of
$15,298.

     In connection with an ongoing Office of Thrift Supervision safety and
soundness examination, the OTS has requested the Bank increase its allowance
for loan losses as of March 31, 1998.  (The OTS has not, however, yet quoted a
recommended amount of loan loss reserves.)  While management notes that none of
the commercial real estate or commercial loans are non-performing at this time,
that type or lending has increased over the last two years.  Accordingly, the
Bank's lending risks have increased because commercial real estate and
commercial loans are generally believed to more risky than other types of
lending such as residential mortgage lending.  Therefore, the Bank has
increased its provision for loan losses of $50,000 for the six months ended
March 31, 1997 to $310,000 for the six months ended March 31, 1998.

(b)  Results of Operations:

     During the three month period ended March 31, 1998, net earnings
decreased to $(172,000) (basic EPS of $(.98) per share) compared to net
earnings of $120,000 (basic EPS of $.68 per share) during the three month
period ended March 31, 1997.  The decrease in earnings is primarily the result
of an increase in the provision loan losses of $378,000 for the three months
ended March 31, 1998.

     Net interest income was $491,000, after provision for loan losses, for the
three months ended March 31, 1998, compared to $631,000 for the three months
ended March 31, 1997.  The interest rate margin for the three months ended
March 31, 1998 was 3.16%, compared to 3.16% for the same period one year ago.

     Interest income increased from $1,668,000 for the three months ended March
31, 1997 to $1,873,000 for the three months ended March 31, 1998.  Interest
expense for the three month period ended March 31, 1998 was $1,101,000 compared
to $1,010,000 for the three months ended March 31, 1997.  This increase is
primarily attributed to the increase in deposit accounts.

     Total non-interest income was $118,000 for the three months ended March
31, 1998, compared to $83,000 for the same period in 1997.

     Non-interest expense totaled $623,000 for the quarter ended March 31, 1998
compared to $528,000 for the same period in the prior year.  The primary
increase in non-interest expense relates to the costs incurred in connection
with the proposed acquisition of the company.

     During the six period ended March 31, 1998, net earnings decreased to
$175,000 (basic EPS of $.01 per share) compared to net earnings of $249,000 
(basic EPS of $1.41 per share) during the six month period ended March 31, 
1997.  The decrease in earnings is primarily the result of an increase in 
loan loss reserves of $385,000 for the six months ended March 31, 1998.

     Net interest income was $1,461,000, after provision for loan losses, for
the six months ended March 31, 1998, compared to $1,307,000 for the six months
ended March 31, 1997.  The interest rate margin for the six months ended March
31,1998 was 3.12%, compared to 3.20% for the same period one year ago.

     Interest income increased from $3,270,000 for the six months ended March
31, 1997 to $3,740,000 for the six months ended March 31, 1998.  Interest
expense for the six month period ended March 31, 1998 was $2,218,000 compared
to $1,914,000 for the six months ended March 31, 1997.  This increase is
primarily attributed to the increase in deposit accounts.

     Total non-interest income was $219,000 for the six months ended March 31,
1998, compared to $168,000 for the same period in 1997.

     Non-interest expense totaled $1,156,000 for the six months ended March 31,
1998 compared to $1,073,000 for the same period in the prior year.  The primary
increase in non-interest expense relates to the costs incurred in connection
with the proposed acquisition of the company.

(c)  Capital Resources and Liquidity

     The Corporation is subject to regulation as a savings and loan holding
company, and is subject to certain restrictions in its dealings with the Bank.
The Bank is subject to the regulatory requirements applicable to a federal
savings bank.

     Current capital regulations required savings institutions to have minimum
tangible capital equal to 1.5% to total assets and a core capital ratio equal
to 3% of total assets.  Additionally, savings institutions are required to meet
a risk based capital ratio equal to 8.0% for risk-weighted assets.  At March
31, 1998, the Bank satisfied its capital requirements.

     The following is a summary of the Bank's regulatory capital and capital
requirements at March 31, 1998 based on capital regulations currently in effect
for savings institutions.

</TABLE>

     Liquidity measures the Bank's ability to meet its savings withdrawals and
lending commitments.  Management believes that the Bank's liquidity is adequate
to meet current requirements, such as the funding of $3,205,000 in loan
commitments as of March 31, 1998.  The Bank maintains liquidity of at least 4%
of net withdrawable assets.  At March 31, 1998, its regulatory liquidity ratio
was 6.07%.

     A Year 2000 Committee has been established by the Corporation consisting
of officers and employees of the Corporation to address problems which could    
arise from the forthcoming Year 2000 rollover.  The Committee is charged with
providing regular reports to the Board of Directors detailing progress in this
area. Based on progress by the

Committee to date, it is not anticipated that the Year 2000 rollover will
present material financial or operational burdens for the Corporation.

     On May 6, 1998, the Office of Thrift Supervision advised the Bank that,
until certain corrective actions are undertaken, the Bank should cease all
commercial real estate and commercial lending.  In light of the pending
acquisition of the Bank by Blue River Bancshares, Inc. (which currently is
expected to close in June, although there can be no guarantee that the
transaction will close then or at a later date), the Board of Directors of the
Bank has determined to cease all such lending while the transaction is pending.
Management does not expect that ceasing to make such loans during that interim
period will have a material adverse effect on the net earnings of the Bank.

     During the last several years, certain environmental monitoring and
remediation has occurred at the Bank's St. Paul branch location and an
adjoining property (which adjoining property was transferred to an unrelated
third party in 1995).  At the conclusion of those environmental efforts, it was
determined that no further environmental remediation was necessary at that
time.  Since then, the Indiana Department of Environmental Management ("IDEM")
has initiated Indiana's Voluntary Remediation Program (the "VRP"). Pursuant to
the VRP, a parcel of real property may be "submitted" and, after successful
completion of testing and monitoring by the applicant and review by IDEM, the
Indiana Governor's office will issue a Certificate of Completion and a
Covenant Not to Sue.  In connection with the proposed acquisition of the Bank
and at the request of Blue River Bancshares, Inc., the Bank agreed in April to
begin the process to submit the St. Paul branch location into the VRP.
Accordingly, the Bank engaged an environmental consultant to assist.

     As mentioned above, when deciding to begin the process, management of the
Bank, based upon prior environmental reports and remediation efforts, believed
that the environmental consultant would only need to undertake monitoring (and
not any remediation) in connection with the VRP.  However, after undertaking
preliminary testing, the consultant informed the Bank that remediation would be
necessary to remove certain liquid phase hydrocarbons (i.e., petroleum-based
liquids).  Accordingly, management asked the consultant to propose what
remediation would be necessary and to estimate the expected cost.  The
consultant did so on May 14, 1998, and estimated the remediation and costs
associated with the VRP to be $145,780.  The Bank has reserved that amount in
its income statement for the periods ending March 31, 1998.  (See the unaudited
Consolidated Statements of Earnings for the three and six months ended March
31, 1998 at the line-item "Non-Interest Expense - Other".)

     Please be advised, however, that the Bank is reviewing the proposal (and
consulting with Blue River Bancshares, Inc.), and the proposal may be revised.
If so revised, the estimated remediation expenses may increase.  (If this
occurs, management of the Bank may decide to increase the reserved amount,
depending upon the magnitude of the change, when the costs are expected to be
incurred, etc.)  Also, please be advised that the environmental consultant has
only provided an estimate, and the actual total costs may be different.  In
addition, certain costs which may be incurred may not be estimated in the
proposal.  However, at this time management does not believe material
additional expenditures in connection with this matter will be necessary during
the foreseeable future.  Please also be advised that the Bank's actions are
voluntary, and have not been required by any governmental agency or body.
(Accordingly, the Bank reserves the right not to proceed with the VRP as to the
St. Paul branch property, although management intents to so proceed at this
time.)  Except for the VRP, no administrative, legal, or other proceeding is
pending in connection with this matter and, to the knowledge of management,
none is threatened.

     There are no other known trends, events, or uncertainties, including
current recommendations by regulatory authorities, that should have, or that
are reasonably likely to have a material effect on the liquidity, capital
resources, or operations of Shelby County Bancorp.
