Subsidiaries' knowledge, no environmental clearances or other governmental
environmental approvals are required for the conduct of Shelby County's, SCSB's
or either of the Subsidiaries' business or consummation of the Transaction.

operator or lessee, of any property on which any substances have been used,
stored, deposited, treated, recycled or disposed of, which substances if known

     (c)   Neither Shelby County, SCSB nor either of the Subsidiaries (i) is in
default in any respect under any agreements pursuant to which it leases real or
personal property, (ii) has knowledge of any default under such agreements by
any party thereto and (iii) has knowledge of any event which, with notice or
lapse of time or both, would constitute a default or a breach thereof.

     4.12. Loans and Investments.  (a)  Except as set forth in the Disclosure
Schedule, SCSB has no loan in excess of $5,000 that has been classified by
regulatory examiners or management of SCSB as "Substandard," "Doubtful" or
"Loss" or in excess of $5,000 that has been identified by accountants or
auditors (internal or external) as having a significant risk of
uncollectability.  The most recent loan watch list of SCSB and a list of all
loans in excess of $5,000 that SCSB has determined to be ninety (90) days or
more past due with respect to principal or interest payments or has placed on
nonaccrual status are set forth in the Disclosure Schedule.

     (b)   All loans reflected in the Shelby County Financial Statements as of
September 30, 1997 and which have been made, extended, renewed, restructured,
approved, amended or acquired since September 30, 1997 (i) have been made for
good, valuable and adequate consideration in the ordinary course of business;
(ii) to the best of SCSB's knowledge, constitute the legal, valid and binding
obligation of the obligor and any guarantor named therein, except to the extent
limited by general principles of equity and public policy or by bankruptcy,
insolvency, fraudulent transfer, reorganization, liquidation, moratorium,
readjustment of debt or other laws of general application relative to or
affecting the enforcement of creditors' rights; (iii)  are evidenced by notes,
instruments or other evidences of indebtedness which are true, genuine and what
they purport to be; and (iv) are secured, to the extent that SCSB has a
security interest in collateral or a mortgage securing such loans, by perfected
security interests or recorded mortgages naming SCSB as the secured party or
mortgagee.

     (c)   The reserves, the allowance for possible loan and lease losses and
the carrying value for real estate owned which are shown on the Shelby County
Financial Statements are adequate in all respects under the requirements of
generally accepted accounting principles applied on a consistent basis to
provide for possible losses on items for which reserves were made, on loans and
leases outstanding and real estate owned as of the respective dates.  To the
best knowledge of SCSB, the aggregate loan balances outstanding as of September
30, 1997, in excess of the reserve for loan losses as of such date, are
collectible in accordance with their respective terms.

     (d)   Shelby County and SCSB have complied in all material respects with
all laws, statutes, rules, regulations and other legal requirements relating to
its loans such that any failure to so comply will not interfere with the
collection of any loan or provide to any borrower any right, claim or action
against Shelby County or SCSB.  Except as set forth in the Disclosure Schedule,
to the best of Shelby County's and SCSB's knowledge, no property in which SCSB
has an interest as collateral to secure a loan or that is held as an asset of
any trust violates any of the Environmental Laws or obligates Shelby County or
SCSB, or the owner or operator of such property, to remediate, treat or
otherwise alter the environmental condition of such property.

statutory, which materially impairs the ability of Shelby County, SCSB or
either of the Subsidiaries to dispose freely of such investment at any time.

repurchase agreements with respect to securities.  All investment securities
and other investments of SCSB are carried on its books in accordance with

directors, officers, employees and agents, including, without limitation, all
liabilities and obligations to the Shelby County Plans.  All obligations and
liabilities of Shelby County, SCSB and the Subsidiaries, whether arising by
operation of law, by contract or by past custom or practice, for all other forms
of compensation which are or may be payable to their current or former
directors, officers, employees or agents have been and are being paid to the
extent required by applicable law or by the plan or contract, and adequate
accruals and reserves for payment therefor have been and are being made by
Shelby County, SCSB and the Subsidiaries in accordance with generally accepted

provided in the Disclosure Schedule, all accruals and reserves referred to in
this Section 4.15 are correctly and accurately reflected and accounted for in
all material respects in the Shelby County Financial Statements and the books,
statements and records of Shelby County, SCSB and the Subsidiaries.

     SCSB is not and has not engaged in any unfair labor practice within the
meaning of the National Labor Relations Act, as amended, and there is no
proceeding or investigation pending or threatened against it with respect
thereto.  There are no, and during the last five (5) years have not been any,
formal, informal or internal charges or complaints of, or any proceedings or
lawsuits pending or threatened involving, discrimination or harassment, nor is
there any investigation pending or threatened before the Equal Employment
Opportunity Commission or any other federal, state or local agency or authority
involving SCSB or any of its present or former directors, employees or agents.

     Except to set forth in the Disclosure Schedule, neither the execution
and delivery of this Agreement nor the consummation of any of the transactions
contemplated hereby, will (a) result in any payment (including, without
limitation, severance, unemployment compensation or golden parachute payment)
becoming due to any director or employee of Shelby County or SCSB from either of
such entities; (b) increase any benefit otherwise payable under any of the
Shelby County Plans or any other plan of program relating to directors or

time of payment of any benefit or amount owed to any present or former director
or employee of Shelby County or SCSB.

     4.16. Taxes, Returns and Reports.  Shelby County, SCSB and the

respects; (b) paid all taxes, assessments and other governmental charges due or
claimed to be due upon each of them or any of their income, properties or

reserve for taxes in the Shelby County Financial Statements as of September 30,
1997 is adequate to cover all of Shelby County's, SCSB's and the Subsidiaries'
tax liabilities (including, without limitation, income taxes and franchise fees)
that may become payable in future periods with respect to any transactions
consummated prior to September 30, 1997.  Neither Shelby County, SCSB nor either
of the Subsidiaries has, or will have, any liability for taxes of any nature for
or with respect to the operation of their respective businesses, including the
business of any subsidiary, or ownership of their assets, including the assets
of any subsidiary, from the date hereof up to and including the Effective Time,
except to the extent set forth in the Subsequent Shelby County Financial
Statements (as hereinafter defined).  Neither Shelby County, SCSB nor either of
the Subsidiaries is currently under audit by any state or federal taxing
authority.  No federal, state or local tax returns of Shelby County, SCSB or
either of the Subsidiaries have been audited by any taxing authority during the
past five (5) years.

     4.17. Deposit Insurance.  The deposits of SCSB are insured by the Federal
Deposit Insurance Corporation in accordance with the Federal Deposit Insurance
Corporation Act, as amended, and SCSB has paid or properly reserved or accrued
for all current premiums and assessments with respect to such deposit
insurance.

     4.18. Insurance.  Set forth in the Disclosure Schedule is a list and brief
description of all policies of insurance (including, without limitation,
blanket bond, directors' and officers' liability insurance, property and
casualty insurance, group health or hospitalization insurance and insurance
providing benefits for employees) owned or held by Shelby County, SCSB or
either of the Subsidiaries on the date hereof or with respect to which Shelby
County, SCSB or either of the Subsidiaries pays any premiums.  Each such policy
is in full force and effect, all premiums due thereon have been paid when due,
and a true, accurate and complete copy thereof has been made available to Blue
River prior to the date hereof.

     4.19. Books and Records.  The books and records of Shelby County, SCSB and
the Subsidiaries are in all material respects complete and correct and

operations, business, assets and capital of Shelby County, SCSB and the
Subsidiaries set forth in the Shelby County Financial Statements.

     4.20. Broker's, Finder's or Other Fees.  Except for the reasonable fees
of Shelby County's attorneys, accountants and investment bankers and the
printing and mailing costs relating to the proxy statement pertaining to the
Merger, all of which will be paid by Shelby County prior to the Effective Time,
no agent, broker or other person acting on behalf of Shelby County, SCSB or
either of the Subsidiaries or acting under any authority of Shelby County, SCSB
or either of the Subsidiaries is or shall be entitled to any commission,

Shelby County signed by at least a majority of its Board of Directors
then in office indicating that Shelby County has received an unsolicited offer
regarding an Acquisition Transaction which the Board of Directors of Shelby
County (i) considers, in the exercise of its fiduciary duties as a Board, to be
substantially superior, taking into account all relevant factors, to the then
current offer of Blue River pursuant to this Agreement and (ii) concludes,
after consultation with its counsel, that its fiduciary duties as a Board
require it to consider (based upon a written opinion of Shelby County's legal
counsel advising the Board to consider) and, in light of such duties, take such
other actions with respect to such unsolicited offer as may be necessary or
appropriate; and such approval may, in all other instances, be provided to
Shelby County when and if Blue River shall, in its sole discretion, determine.
This Section 6.05 shall not authorize Shelby County, SCSB or either of the

would have been required to be set forth or described in the Disclosure
Schedule or this Agreement and including, without limitation, any fact which,
if existing or known as of the date hereof, would have made any of the
representations or warranties of Shelby County or SCSB contained herein
materially incorrect, untrue or misleading.

     6.8.  Information, Access Thereto, Confidentiality.  Blue River and its
attorneys, accountants, representatives, advisors and agents shall, at all
times during normal business hours prior to the Effective Time, have full and
continuing access to the properties, facilities, operations, books and records
of Shelby County, SCSB and the Subsidiaries.  Blue River and its attorneys,
accountants, representatives, advisors and agents may, prior to the Effective
Time, make or cause to be made such reasonable investigation (including,
without limitation, any environmental review study, survey or assessment of
Shelby County's, SCSB's or any Subsidiary's real properties) of the operations,
books, records and properties of Shelby County, SCSB and the Subsidiaries and
of their financial and legal condition as deemed necessary or advisable to
familiarize themselves with such operations, books, records, properties and
other matters; provided, however, that such access or investigation shall not
interfere unnecessarily with the normal operations of Shelby County, SCSB or
either of the Subsidiaries; and provided further, that if Blue River elects to
conduct or have conducted on its behalf an environmental review, study, survey

River, or its attorneys, accountants, representatives, advisors or agents,
Shelby County's attorneys' responses to external auditors requests for
information, management letters received from its external auditors and such
financial, loan and operating data and other information reasonably requested
by Blue River which has been or is developed by Shelby County, SCSB or either
of the Subsidiaries or their auditors, accountants or attorneys (provided with
respect to attorneys, such disclosure would not result in the waiver by Shelby
County, SCSB or either of the Subsidiaries of any claim of attorney-client
privilege), and will permit Blue River and its respective representatives or
agents to discuss such information directly with any individual or firm
performing auditing or accounting functions for Shelby County, SCSB or either
of the Subsidiaries, and such auditors and accountants shall be directed to
furnish copies of any reports or financial information as developed to Blue
River or its auditors or accountants.  No investigation or review by Blue River
(whether conducted before or after the date hereof) shall affect the
representations and warranties made by Shelby County or SCSB herein or the
information contained in any document provided hereunder, and Blue River shall
be entitled to rely on such representations, warranties and documents
notwithstanding any such investigation or review.  Any confidential information
or trade secrets received by Blue River or its representatives or agents in the
course of such examination shall be treated confidentially, and any
correspondence, memoranda, records, copies, documents and electronic or other
media of any kind containing such confidential information or trade secrets or
both shall be destroyed by Blue River or, at Shelby County's request, returned

Section 9 hereof.  This Section 6.08 shall not require the disclosure of any
information to Blue River which would be prohibited by law.

Statements").  The Subsequent Shelby County Financial Statements shall be
prepared on a basis consistent with past accounting practices and generally
accepted accounting principles applied on a consistent basis and shall present
fairly the financial condition and results of operations as of the dates and
for the periods presented.  The Subsequent Shelby County Financial Statements
will not include any assets, liabilities or obligations or omit to state any
assets, liabilities or obligations, absolute or contingent, or any other facts,
which inclusion or omission would render such financial statements inaccurate,
incomplete or misleading in any material respect.

     6.10. Employee Benefits.  Neither the terms of Section 7.03 hereof
(except as otherwise expressly provided therein) nor the provision of any
employee benefits by Blue River or any of its subsidiaries to employees of
Shelby County, SCSB and the Subsidiaries shall (i) create any employment

Blue River or its subsidiaries, whether before or after the Effective
Time, from changing, amending or terminating any employee benefits provided to
its employees from time to time.

     6.11. Employment Agreements.  Prior to the Effective Time, SCSB shall use
all reasonable efforts to cause the employment agreements between SCSB and each
of Ronald L. Lanter,  Joyce E. Ford and Rita Sturgill (each in the form set
forth in the Disclosure Schedule) (collectively referred to herein as the
"Employment Agreements") to be amended, all in form and substance reasonably
satisfactory to Blue River, such that (i) the requirement that each participate
in a stock option plan shall be deleted and all references as to title other
than the title of Vice President shall be deleted, (ii) each will receive
employee benefits in accordance with Blue River's employee benefit plans
instead of SCSB's plans and (iii) the term of each of the Employment Agreements
shall end one (1) year from the Effective Time.  Other than the foregoing
amendments, the Employment Agreements shall not be amended or modified in any
respect, and none of the respective terms of the Employment Agreements shall be
extended or renewed.  On the date hereof, SCSB and Rodney L. Meyerholtz shall
enter into an agreement relating to the Meyerholtz Agreement ("Termination
Agreement") to the effect that the Meyerholtz Agreement shall be terminated as
of the Effective Time upon the terms and conditions specified in the
Termination Agreement.  Other than as set forth in the Termination Agreement,
the Meyerholtz Agreement shall not be changed, amended or modified in any
respect and the term thereof shall not be extended or renewed without the prior
written consent of Blue River, SCSB and Mr. Meyerholtz.

     6.12. Certain Actions.  Neither Shelby County, SCSB nor either of the
Subsidiaries shall intentionally or knowingly take, cause to be taken or fail
to take any action which will cause or result in a misrepresentation or a
breach of a covenant or warranty of this Agreement that will give Blue River
the right to terminate this Agreement pursuant to Section 9.01(b) hereof or
which will result in a condition precedent to consummation of the Transaction
not to be satisfied or fulfilled.

     6.13. Restructure.  Shelby County and SCSB understand, acknowledge and
agree that Blue River, in its sole discretion, may change the structure of the
transactions contemplated by this Agreement; provided, however, that any such
change in structure shall not affect the Conversion Price or the consideration
to be paid hereunder to the shareholders of Shelby County or cause the
consummation of the Transaction to be delayed.  Shelby County and SCSB shall
execute and deliver such amendments, agreements and instruments and take such
further actions as Blue River may reasonably request in connection with any
such restructure of the transactions contemplated by this Agreement.


                                  SECTION 7

                           COVENANTS OF BLUE RIVER

           required for consummation of the Transaction, except for the

Proxy Statement.  Blue River shall file all such applications as soon
as practicable after the execution of this Agreement.  Blue River shall provide
to Shelby County's counsel copies of all applications filed and copies of all
material written communications with all state and federal bank regulatory

expeditiously, cooperate fully and use its best efforts to procure, upon terms
and conditions reasonably acceptable to Blue River, all consents,
authorizations, approvals, registrations and certificates, to complete all
filings and applications and to satisfy all other requirements prescribed by
law which are necessary for consummation of the Transaction on the terms and
conditions provided in this Agreement at the earliest possible reasonable date,
except as set forth in Section 6.01 hereof.

     (b)   Blue River shall submit this Agreement to its shareholders for
approval at a meeting to be called and held in accordance with applicable law
and the Articles of Incorporation and By-Laws of Blue River at a date
reasonably in advance of the Effective Time and the Board of Directors of Blue
River shall recommend, by at least a majority vote, to Blue River's
shareholders that such shareholders approve this Agreement and the Merger.

     7.02. SEC Registration.  Blue River shall file with the SEC as soon as
practicable after the execution of this Agreement a Registration Statement on
an appropriate form under the 1933 Act covering the shares of Blue River common
stock to be sold in its initial public offering ("IPO").  Such Registration
Statement and any amendments and supplements thereto are referred to in this
Agreement as the "Registration Statement."  The Registration Statement shall
include a prospectus ("Prospectus") relating to the shares of Blue River common
stock to be sold in the IPO.  In advance of filing the Registration Statement
and all other filings described in Section 7.01 hereof, Blue River shall
provide Shelby County and its counsel with a copy of the Registration Statement
and each such other filing and provide an opportunity to comment thereon.

     7.03. Blue River Benefit Plans.  (a) General.  Blue River will make
available to the employees of SCSB who continue as employees of SCSB after the
Effective Time such employee benefits as the Board of Directors of Blue River
may determine to provide to employees from time to time.  Until such time as
the employees of SCSB become eligible to participate in or eligible to be
covered by Blue River's employee pension benefit plans or employee welfare
benefit plans, employees of SCSB who would otherwise be eligible to participate
in or be covered by the employee pension benefit and employee welfare benefit
plans of Blue River under the terms thereof shall remain participants in or
covered by the employee pension benefit plans and employees welfare benefit
plans of Shelby County in existence at the Effective Time, subject to the terms
of such plans, to the extent provided by such plans of Shelby County. 
Notwithstanding the foregoing or anything herein to the contrary, Blue River
shall not be obligated to provide any employee benefit plans to employees of
SCSB following the Merger who meet the applicable eligible requirements except
for the Blue River Profit Sharing Plan (as hereinafter defined) and group
health and hospitalization insurance.

     (b)   Eligibility and Vesting.  Years of service, as defined in the
applicable Blue River employee welfare or pension benefit plan, with SCSB prior
to the Effective Time shall be credited to each employee of SCSB eligible for
coverage under Section 7.03(a) hereof for purposes of (i)


                                    -35-



<PAGE>   36



eligibility under Blue River's employee welfare benefit plans; and (ii)
eligibility and vesting, but not for purposes of benefit accrual or
contributions, under the Blue River Employees' Savings and Profit Sharing Plan
("Blue River Profit Sharing Plan"). The employees of SCSB shall become covered
by Blue River's employee pension and welfare benefit plans at such time(s) as
shall be specified by Blue River in its sole discretion, subject to Section
7.03(a) hereof.  The service credit provided by this Section 7.03(b) will
become effective for a plan on the date Blue River specifies pursuant to the
preceding sentence.  Those officers and employees of SCSB who otherwise meet
the eligibility requirements of the designated plan, based upon their age and
years of service for SCSB and Blue River, shall become participants thereunder
on the entry date which coincides with or next follows the specified date. 
Those officers and employees of SCSB who do not meet the eligibility
requirements of the designated plan on such date shall become participants
thereunder on the first plan entry date which coincides with or next follows
the date on which such eligibility requirements are satisfied.

     (c)   Financial Institutions Retirement Fund.  The accrual of participants'
benefits under SCSB's Financial Institutions Retirement Fund ("SCSB Retirement
Plan") shall be frozen effective as of December 31st of the year in which the
Effective Time occurs, and all accrued benefits of participants in the SCSB
Retirement Plan shall thereupon become fully vested.  To the extent permitted
by the SCSB Retirement Plan and applicable law, the accrued benefit of each
participant in the SCSB Retirement Plan shall be held and remain under the SCSB
Retirement Plan and shall be payable at the time(s) and in the forms provided
for under that plan.  Blue River shall be responsible for the withdrawal of
SCSB from the SCSB Retirement Plan and for making any required or appropriate
application to the Service for a determination letter to the effect that such
withdrawal does not adversely affect the tax-qualified status of such plan and
for providing any notices to the Pension Benefit Guaranty Corporation or other
governmental entity regarding the withdrawal.  SCSB shall make contributions to
the SCSB Retirement Plan through the date of such withdrawal only to the extent
required to maintain the plan's tax-qualified status and avoid any federal
income taxes or penalties attributable to the plan's funding status.

     7.04. Press Releases.  Except as required by law, Blue River shall not
issue any press releases or make any other public announcements or disclosures
relating primarily to Shelby County, SCSB or either of the Subsidiaries with
respect to the Transaction without the prior consent of Shelby County, which
consent shall not be unreasonably withheld.

     7.5.  Information, Access Thereto, Confidentiality.  Shelby County and
its attorneys, accountants, representatives, advisors and agents shall, at all
times during normal business hours prior to the Effective Time, have full and
continuing access to the facilities, operations, books, records and properties
of Blue River.  Shelby County and its attorneys, accountants, representatives,
advisors and agents may, prior to the Effective Time, make or cause to be made
such reasonable investigation of the operations, books, records and properties
of Blue River and of its financial and legal condition as Shelby County shall
deem reasonable necessary or advisable to familiarize itself with such books,
records, properties and other matters; provided, however, that such access or
investigation shall not interfere unnecessarily with the normal operations of
Blue River.  No investigation or review by Shelby County (whether conducted
before or after the date hereof) shall 


                                    -36-

affect the representations and warranties made by Blue River or the
information contained in any document provided herein, and Shelby County shall
be entitled to rely on such representations, warranties and documents
notwithstanding any such investigation or review.  Any confidential information
or trade secrets received by Shelby County or its respective employees or
agents in the course of such examination shall be treated confidentially, and
any correspondence, memoranda, records, copies, documents and electronic or
other media of any kind containing such confidential information or trade
secrets or both shall be destroyed by Shelby County or, at Blue River's
request, returned to Blue River in the event this Agreement is terminated as
provided in Section 9 hereof.  This Section 7.05 shall not require the
disclosure of any information to Shelby County which would be prohibited by
law.

     7.06. Employment Agreements.  Following the Effective Time, Blue River
agrees to cause SCSB to assume all obligations under the Employment Agreements,
as amended pursuant to Section 6.11 hereof, except as may be otherwise required
by law or any government agency or authority.

     7.07. Indemnification.  Blue River shall cause SCSB to keep the
indemnification provisions in SCSB's Charter in effect on the date hereof in
full force and effect for a period of not less than two (2) years following the
Effective Time.

     7.08. Termination Fee.  (a) Blue River hereby acknowledges and agrees that
Shelby County and SCSB have committed and will commit substantial time, effort,
resources and expenses in pursuing the Transaction.  Blue River further agrees
that it shall pay to Shelby County a termination fee in the amount the amount
of One Hundred Thousand Dollars ($100,000) in immediately available funds
("Termination Fee"), in the event that Shelby County terminates this Agreement
pursuant to Section 9.01(c)(i), 9.01(c)(ii), 9.01(c)(iii) or 9.01(c)(iv)
hereof.

     (b)   The Termination Fee shall be immediately paid to Shelby County upon
the termination of this Agreement by Shelby County pursuant to Section 9.01(c)
hereof.  If the Termination Fee is not immediately paid as provided, then
Shelby County shall be entitled to recover interest at the highest prime rate
set forth in The Wall Street Journal (Midwest Edition) under the section
entitled "Money Rates" on the unpaid amount of the Termination Fee from the
time the Termination Fee is due until paid-in-full, together with all costs of
collection thereof, including reasonable attorneys' fees and expenses.

     (c)   Blue River, Shelby County and SCSB hereby acknowledge and agree
that the Termination Fee shall compensate Shelby County and SCSB for (i)
certain expenses incurred for attorneys, accountants, financial advisors and
consultants of Shelby County and SCSB in developing the Transaction and
drafting this Agreement, (ii) Shelby County and SCSB's management time and
expense in investigating, analyzing, developing and pursuing the Transaction,
and (iii) expenses relating to Shelby County and SCSB's due diligence efforts. 
Blue River further acknowledges and agrees that the amount of the Termination
Fee is fair, reasonable and not a penalty and that its obligation to pay the
Termination Fee shall survive any termination of this Agreement by Shelby
County or SCSB.

                   in connection with the execution of an underwriting
                   agreement); provided, however, that before Shelby County may
                   exercise its right to terminate this Agreement pursuant to
                   this Section 9.01(c)(iv), Blue River shall have thirty (30)
                   days from the date of such withdrawal to obtain a letter of
                   intent or similar document from another investment banker
                   with respect to the intent of such other investment banker
                   to act as the principal underwriter in the IPO.

     9.02. Effect of Termination.  Upon termination by written notice, this
Agreement shall be of no further force or effect, and there shall be no further
obligations or restrictions on future activities on the part of Blue River,
Shelby County, SCSB and their respective directors, officers, employees, agents
and shareholders, except as provided in compliance with the confidentiality
provisions of this Agreement set forth in Section 6.08 and Section 7.05 hereof,
for the payment of the Termination Fee as provided by Section 7.08 hereof and
for the payment of expenses set forth in Section 12.09 hereof; provided,
however, the damages of Shelby County and SCSB relating to this Agreement and
the Transaction shall be limited solely to the Termination Fee; provided,
further, if such termination was the result of an intentional breach by Shelby
County or SCSB of any representation, warranty, covenant or other provision in
this Agreement, or an intentional act or omission by Shelby County or SCSB
which resulted in any representation, warranty, covenant or other provision in
this Agreement to be breached, Shelby County and SCSB shall be liable to Blue
River for damages and all costs and expenses incurred in connection with the
preparation, negotiation and execution of this Agreement, including, but not
limited to, reasonable attorneys' fees and disbursements, reasonable fees and
disbursements of accountants and tax advisors, and reasonable fees and costs of
environmental consultants.  In the event that this Agreement is terminated
pursuant to this Section 9, the parties hereto each agree that Roney & Co. and
any other investment banking firm engaged by Blue River shall have no liability
relating to the failure of Blue River to fulfill the conditions contemplated by
Section 8.01(d) hereof.
