                          AGREEMENT AND PLAN OF MERGER
                          ----------------------------
         THIS AGREEMENT AND PLAN OF MERGER, dated as of July 25, 1994
("Agreement"), is made by and between National City Corporation, a Delaware
corporation ("NCC") and Central Indiana Bancorp, an Indiana Corporation
("Company").
         WHEREAS, NCC and Company have each determined that it is in the best
interests of their respective stockholders for Company to merge with and into
NCC upon the terms and subject to the conditions set forth herein;
         WHEREAS, the Boards of Directors of NCC and Company have approved this
Agreement and the consummation of the transactions contemplated hereby and
approved the execution and delivery of this Agreement;
         WHEREAS, for Federal income tax purposes, it is intended that the
merger shall qualify as a reorganization under the provisions of Section 368 of
the Internal Revenue Code of 1986, as amended (the "Code"); and
         WHEREAS, as a condition to, and immediately after the execution of
this Agreement, the parties are entering into the Option Agreement (as
hereinafter defined);
         NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties and agreements contained herein, the parties hereto
hereby agree as follows:

                                I.  THE MERGER
                                    ----------
         1.1  MERGER.  Subject to the terms and conditions of this Agreement,
at the Effective Time (as defined in Section 1.2), Company will be merged with
and into NCC and the separate corporate existence of the Company will
thereupon cease (the "Merger") in accordance with the applicable provisions of
Title 23 of the Indiana Code ("IC") and the Delaware General Corporation Law
("DGCL").  First Federal Savings Bank of Kokomo ("Kokomo"), the Company's
subsidiary, will be merged into National City Bank, Indiana ("NCB") at the
Effective Time or as soon as practicable thereafter.
         1.2  EFFECTIVE TIME.  As soon as practicable after satisfaction or
waiver of all conditions to the Merger, NCC and Company shall cause a
certificate of merger complying with the requirements of the DGCL (the
"Certificate of Merger") to be filed with the Secretary of State of the State
of Delaware and Articles of Merger to be filed with the Secretary of State of
the State of Indiana ("Articles of Merger") pursuant to IC.  The Merger will
become effective at the time the later of the following occurs: (a) the filing
of the Certificate of Merger with the Secretary of State
<PAGE>   7
of the State of Delaware and  (b) the filing of the Articles of Merger with the
Secretary of State of the State of Indiana or such later time as shall be
specified in such filings ("Effective Time").
         1.3  EFFECT OF MERGER.  The Merger will have the effects specified in
IC and DGCL.  Without limiting the generality of the foregoing, NCC will be the
surviving corporation in the Merger (sometimes hereinafter referred to as the
"Surviving Corporation") and will continue to be governed by the laws of the
State of Delaware, and the separate corporate existence of NCC and all of its
rights, privileges, powers and franchises, public as well as private, and all
its debts, liabilities and duties as a corporation organized under the DGCL,
will continue unaffected by the Merger.
         1.4  CERTIFICATE OF INCORPORATION AND BY-LAWS.  The Certificate of
Incorporation and By-laws of NCC in effect immediately prior to the Effective
Time, which shall be in the form set forth in the NCC Disclosure Letter (as
defined below), shall be the Certificate of Incorporation and By-laws of the
Surviving Corporation, unless or until amended in accordance with applicable
law.
         1.5  DIRECTORS AND OFFICERS.  The directors and officers of NCC
immediately prior to the Effective Time will be the directors and officers,
respectively, of the Surviving Corporation, from and after the Effective Time,
until their successors have been duly elected or appointed and qualified or
until their earlier death, resignation or removal in accordance with the terms
of the Surviving Corporation's Certificate of Incorporation and By-laws and the
DGCL.
         1.6  ADDITIONAL ACTIONS.  If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any further deeds,
assignments or assurances in law or any other acts are necessary or desirable
to (i) vest, perfect or confirm, of record or otherwise, in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of Company, or (ii) otherwise carry out the purposes of
this Agreement, Company and its officers and directors shall be deemed to have
granted to the Surviving Corporation an irrevocable power of attorney to
execute and deliver all such deeds, assignments or assurances in law or any
other acts as are necessary or desirable to (i) vest, perfect or confirm, of
record or otherwise, in the Surviving Corporation its right, title or interest
in, to or under any of the rights, properties or assets of Company or (ii)
otherwise carry out the purposes of this Agreement, Company and its officers
and directors shall be deemed to have granted to the Surviving


                                     -2-
<PAGE>   8





Corporation an irrevocable power of attorney to execute and deliver all such
deeds, assignments or assurances in law and to all acts necessary or proper to
vest, perfect or confirm title to and possession of such rights, properties or
assets in the Surviving Corporation and otherwise to carry out the purposes of
this Agreement, and the officers and directors of the Surviving Corporation are
authorized in the name of Company or otherwise to take any and all such action.

                          II.  CONVERSION OF SHARES
                               --------------------
         2.1  CONVERSION OF SHARES.  Subject to Section 2.3, at the Effective
Time,
                 (a)  each then-outstanding share of common stock, no par
value, of Company ("Company Common Stock") other than shares owned by NCC or
any direct or indirect wholly-owned subsidiary of NCC (except that any such
shares of Company Common Stock held in trust accounts, managed accounts or in
any similar manner as trustee or in a fiduciary capacity ("Trust Account
Shares") or acquired in satisfaction of debts previously contracted ("DPC
Shares") shall not be deemed owned by NCC) and other than those shares of
Company Common Stock held in the treasury of the Company, will be canceled,
retired and converted into a right to receive 1.08 shares of common stock, par
value $4.00 per share, of NCC ("NCC Common Stock").  The number of shares of
NCC Common Stock that each share of Company Common Stock will be converted into
is sometimes referred to herein as the "Merger Consideration";
                 (b)  each then-outstanding share of Company Common Stock owned
by NCC or any direct or indirect wholly-owned subsidiary of NCC (except for any
shares that are Trust Account Shares or DPC Shares) will be canceled and
retired;
                 (c)  each share of Company Common Stock issued and held in
Company's treasury will be canceled and retired; and 
                 (d)  each share of NCC Common Stock issued and outstanding 
immediately prior to the Effective Time shall continue to be an issued and 
outstanding share of common stock, par value $4.00 per share, of the
Surviving Corporation from and after the Effective Time.  

         2.2  ASSUMPTION OF EMPLOYEE AND DIRECTOR STOCK OPTIONS.  Except as
expressly provided in this Section 2.2, all rights under any stock option 
granted by Company pursuant to Company's Stock Option Plan and Company's 1993 
Stock Option Plan (collectively, the "Company Option





                                      -3-
<PAGE>   9





Plans") that remain unexercised immediately prior to the Effective Time
("Unexercised Options") shall be assumed by NCC, but shall thereafter represent
the right to acquire that number of shares of  NCC Common Stock to which the
optionee would have been entitled pursuant to the conversion ratio provided for
in Section 2.1(a) if immediately prior to the Merger the optionee had fully
exercised the option and had been a shareholder of record of Company.  The
option price of each option shall be adjusted to the extent necessary to assure
that the rights and benefits of the optionee under such option shall not be
increased or decreased by reason of this Section 2.2, and, in addition, each
option which is an incentive stock option shall be adjusted as required by
section 424 of the Code, and the regulations promulgated thereunder so as not
to constitute a modification, extension or renewal of the option within the
meaning of section 424(h) of the Code.  On or before the Effective Time NCC
shall file, and maintain the effectiveness of, a registration statement with
the Securities and Exchange Commission covering the Unexercised Options and the
sale of the NCC Common Stock issued upon exercise of Unexercised Options.  At
the Effective Time all Company Option Plans shall be terminated with respect to
the granting of any additional options or option rights.
         2.3  EXCHANGE OF CERTIFICATES.
                 (a)  EXCHANGE AGENT.  Prior to the Effective Time, NCC shall
designate National City Bank to act as exchange agent (the "Exchange Agent")
and Kokomo to act as forwarding agent in connection with the Merger pursuant to
an exchange agent agreement providing for, among other things, the matters set
forth in this Section 2.3.  Except as set forth herein, from and after the
Effective Time each holder (other than NCC or any direct or indirect
wholly-owned subsidiary of NCC (except as to Trust Account Shares and DPC
Shares)) of a certificate that immediately prior to the Effective Time
represented outstanding shares of Company Common Stock ("Certificate") shall be
entitled to receive in exchange therefor, upon surrender thereof to the
Exchange Agent, the Merger Consideration for each share of Company Common Stock
so represented by the Certificate surrendered by such holder thereof.  The
certificates representing shares of NCC Common Stock which constitute the
Merger Consideration shall be properly issued and countersigned and executed
and authenticated, as appropriate.
                 (b)  NOTICE OF EXCHANGE.  Promptly after the Effective Time,
NCC and the Surviving Corporation shall cause the Exchange Agent to mail and/or
make available to each





                                      -4-
<PAGE>   10





record holder of a Certificate a notice and letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificate shall pass, only upon proper delivery of the Certificate to the
Exchange Agent) advising such holder of the effectiveness of the Merger and the
procedures to be used in effecting the surrender of the Certificate for
exchange therefor.  Upon surrender to the Exchange Agent of a Certificate,
together with such letter of transmittal duly executed and completed in
accordance with the instructions thereon, and such other documents as may
reasonably be requested, the Exchange Agent shall promptly deliver to the
person entitled thereto the appropriate Merger Consideration for each share of
Company Common Stock so represented by the Certificate surrendered by such
holder thereof, and such Certificate shall forthwith be canceled.
                 (c)  TRANSFER.  If delivery of all or part of the Merger
Consideration is to be made to a person other than the person in whose name a
surrendered Certificate is registered, it shall be a condition to such delivery
or exchange that the Certificate surrendered shall be properly endorsed or
shall be otherwise in proper form for transfer and that the person requesting
such delivery or exchange shall have paid any transfer and other taxes required
by reason of such delivery or exchange in a name other than that of the
registered holder of the Certificate surrendered or shall have established to
the reasonable satisfaction of the Exchange Agent that such tax either has been
paid or is not payable.
                 (d)  RIGHT TO MERGER CONSIDERATION.  Subject to Subsection
2.3(e), until surrendered and exchanged in accordance with this Section 2.3,
each Certificate shall, after the Effective Time, represent solely the right to
receive the Merger Consideration, multiplied by the number of shares of Company
Common Stock evidenced by such Certificate, together with any dividends or
other distributions as provided in Sections 2.3(e) and 2.3(g), and shall have
no other rights.  From and after the Effective Time, NCC and Surviving
Corporation shall be entitled to treat such Certificates that have not yet been
surrendered for exchange as evidencing the ownership of the aggregate Merger
Consideration into which the shares of Company Common Stock represented by such
Certificates may be converted, notwithstanding any failure to surrender such
Certificates.  One hundred eighty (180) days following the Effective Time, the
Exchange Agent shall deliver to the Surviving Corporation any shares of NCC
Common Stock and funds (including any interest received with respect thereto)
which NCC has made available





                                      -5-
<PAGE>   11





to the Exchange Agent and which have not been disbursed to holders of
Certificates, and thereafter such holders shall be entitled to look to the
Surviving Corporation (subject to abandoned property, escheat or other similar
laws) with respect to the shares of NCC Common Stock and cash in lieu of
fractional shares deliverable or payable upon due surrender of their
Certificates.  Neither Exchange Agent nor any party hereto shall be liable to
any holder of shares of Company Common Stock for any Merger Consideration (or
dividends, distributions or interest with respect thereto) delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.
                 (e)  DISTRIBUTION WITH RESPECT TO UNEXCHANGED CERTIFICATES.
Whenever a dividend or other distribution is declared by NCC on the NCC Common
Stock, the record date for which is at or after the Effective Time, the
declaration shall include dividends or other distributions on all shares
issuable pursuant to this Agreement, provided that no dividends or other
distributions declared or made with respect to NCC Common Stock with a record
date that is more than 30 days after the mailing of the Certificate of notice
and letter of transmittal provided for under Subsection 2.3(b) of this
Agreement shall be paid to the holder of any unsurrendered Certificate with
respect to the share of NCC Common Stock represented thereby until the holder
of such Certificate shall surrender such Certificate in accordance with this
Article II.  The Surviving Corporation shall pay any dividends or make any
other distributions with a record date prior to the Effective Time which may
have been declared or made by the Company on Company Common Stock in accordance
with the terms of this Agreement on or prior to the Effective Time and which
remain unpaid at the Effective Time.
                 (f)  VOTING WITH RESPECT TO UNEXCHANGED CERTIFICATES.  Holders
of unsurrendered Certificates shall be entitled to vote after the Effective
Time at any meeting of NCC stockholders the number of whole shares of NCC
Common Stock represented by such Certificates, regardless of whether such
holders have exchanged their Certificates, provided that no holder of
unsurrendered Certificates may vote at any meeting  of NCC stockholders that is
held more than 30 days after the mailing of the Certificate of notice and
letter of transmittal provided for under Subsection 2.3(b) of this Agreement.
                 (g)  NO FRACTIONAL SHARES.  No certificates or script
representing fractional shares of NCC Common Stock shall be issued upon the
surrender for exchange of a Certificate or





                                      -6-
<PAGE>   12





Certificates.  No dividends or distributions of NCC shall be payable on or with
respect to any fractional share and any such fractional share interest will not
entitle the owner thereof to vote or to any rights of stockholders of NCC.  In
lieu of any such fractional shares, holders of Certificates otherwise entitled
to fractional shares shall be entitled to receive promptly from the Exchange
Agent a cash payment in an amount equal to the fraction of such share of NCC
Common Stock to which such holder would otherwise be entitled multiplied by the
Market Price, as defined in Section 8.6(a)(iii).
         2.4  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  The stock transfer
books of Company shall be closed at the close of business on the business day
immediately preceding the date of the Effective Time.  In the event of a
transfer of ownership of Company Common Stock which is not registered in the
transfer records of Company, the Merger Consideration to be distributed
pursuant to this Agreement may be delivered to a transferee, if a Certificate
is presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by payment of any applicable stock
transfer taxes.  NCC and the Exchange Agent shall be entitled to rely upon the
stock transfer books of Company to establish the identity of those persons
entitled to receive the Merger Consideration specified in this Agreement for
their shares of Company Common Stock, which books shall be conclusive with
respect to the ownership of such shares.  In the event of a dispute with
respect to the ownership of any such shares, the Surviving Corporation and the
Exchange Agent shall be entitled to deposit any Merger  Consideration
represented thereby in escrow with an independent party and thereafter be
relieved with respect to any claims to such Merger Consideration.
         2.5  CHANGES IN NCC COMMON STOCK.  If between the date of this
Agreement and the Effective Time, the shares of NCC Common Stock shall be
changed into a different number of shares by reason of any reclassification,
recapitalization, split-up, combination or exchange of shares, or if a stock
dividend thereon shall be declared with a record date within said period, the
Merger Consideration shall be adjusted to reflect such reclassification,
recapitalization, split-up, combination, exchange of shares or stock dividend.

validly existing and in good standing under the laws of the State of Delaware
and is duly qualified to do business as a foreign corporation in each
jurisdiction in which its ownership or lease of property or the nature of the
business conducted by it makes such qualification necessary, except for such
jurisdictions in which the failure to be so qualified would not have a Material
Adverse Effect.  NCC is registered as a bank holding company under the Bank
Holding Company Act of 1956, as amended (the "BHCA").  NCC has the requisite
corporate power and authority to own, lease and operate its properties and
assets and to carry on its business as it is now being conducted.  NCC has
heretofore delivered to Company true and complete copies of its certificate of
incorporation and by-laws.
         3.2  AUTHORITY.  Subject to the receiving all applicable regulatory
approvals, NCC has the requisite corporate power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated by this
Agreement.  The execution and delivery of this Agreement and the consummation
of the transactions contemplated hereby have been duly approved by the Board of
Directors of NCC.  This Agreement has been duly executed and delivered by, and
constitutes a valid and binding obligation of, NCC, enforceable against NCC in
accordance with its terms, except as enforceability thereof may be limited by
applicable bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and other similar laws affecting the enforcement of creditors'
rights generally and except that the availability of the equitable remedy of
specific performance or injunctive relief is subject to the discretion of the
court before which any proceedings may be brought.  No other corporate
proceedings on the part of NCC are necessary to authorize this Agreement or to
consummate the transactions so contemplated.
         3.3   CAPITALIZATION.  As of the date hereof, the authorized capital
stock of NCC consists of 350,000,000 shares of NCC Common Stock and 5,000,000

hereof, except as provided in this Agreement or as set forth in the NCC
Disclosure Letter, there are no voting trusts or other agreements or
understandings to which NCC or any NCC subsidiary (as defined herein) is a
party with respect to the voting of the capital stock of NCC.  Except as set
forth in NCC's proxy statement dated March 4, 1994 or in NCC's Disclosure
Letter, NCC knows of no person who owns beneficially or has the right to
acquire more than five percent of the outstanding NCC Common Stock.  All of the

failure to be so qualified would not have a Material Adverse Effect.  Each of
NCC's subsidiaries has the requisite corporate power and authority to own,

they are now being conducted.  Except as set forth in the NCC Disclosure
Letter, all outstanding shares of capital stock of each of NCC's subsidiaries
are owned by NCC or another of NCC's subsidiaries and are validly issued, fully

bank subsidiary and applicable state law in the case of each state bank
subsidiary) nonassessable, are not subject to preemptive rights and are owned
free and clear of all material liens, claims and encumbrances.  There are no
outstanding subscriptions, options, warrants, rights, convertible securities or
any other agreements or commitments of any character relating to the issued or
unissued capital stock or other securities of any NCC subsidiary obligating any
of NCC subsidiaries to issue, deliver or sell, or cause to be issued, delivered
or sold additional shares of its capital stock or obligating any of NCC's
subsidiaries to grant, extend or enter into any subscription, option, warrant,

regulations promulgated thereunder.  
         3.6  CONSENTS AND APPROVALS; NO VIOLATION.  Except as set forth in the 
NCC Disclosure Letter, neither the execution and delivery of this Agreement by 
NCC nor the consummation by NCC of the transactions contemplated hereby will 
(a) conflict with or result in any breach of any provision of its certificate 
of incorporation or by-laws, (b) violate, conflict with, constitute a default

their respective properties or assets are subject, except for such violations, 
conflicts, breaches, defaults, terminations, accelerations or creations of

respective dates, the NCC Reports complied with the requirements of the
Commission and did not contain any untrue statement of a material fact or omit

estimated tax, withholding tax, franchise, sales and other tax returns or
reports required to be filed by them on or before the date hereof, except to
the extent that all such failures to file, taken together, would not have a
Material Adverse Effect.  NCC and each of its subsidiaries have paid, or have
made adequate provision or set up an adequate accrual or reserve for the
payment of, all taxes, shown or required to be shown to be owing on all such
returns or reports, together with any interest, additions or penalties related

requirements of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), the Code, and any other applicable laws.  With respect to each NCC
Employee Plan which is a pension plan (as defined in Section 3(2) of ERISA):
(a) except for recent amendment(s) to the plans not materially affecting the
qualified status of the plans (which are disclosed in the NCC Disclosure
Letter), and except as otherwise set forth in the NCC Disclosure Letter, each
pension plan as amended (and any trust relating thereto) intended to be a

the Internal Revenue Service ("IRS") to be so qualified or is the subject of a
pending application for such determination that was timely filed, (b) there is

                                      -13-

which the 30 day reporting requirement has not been waived has occurred, (f)
except as otherwise set forth in the NCC Disclosure Letter, no defined benefit
plan has been terminated, nor has the Pension Benefit Guaranty Corporation

appoint a trustee or administrator of a defined benefit plan, and no
circumstances exist that constitute grounds under Section 4042(a)(2) of ERISA
entitling the PBGC to institute any such proceedings and (g) no pension plan is
a "multiemployer plan" within the meaning of Section 3(37) of ERISA.  Neither
NCC nor any of its subsidiaries has incurred any liability to the PBGC with
respect to any "single-employer plan" within the meaning of Section 4001(a)(15)
of ERISA currently or formerly maintained by any entity considered one employer
with it under Section 4001 of ERISA or Section 414 of the Code, except for

person in any calendar year in excess of $500,000, (b) any material agreement,
indenture or other instrument relating to the borrowing of money by NCC or any
of its subsidiaries or the guarantee by NCC or any of its subsidiaries of any
such obligation (other than trade payables and instruments relating to
borrowings or guaranties made in the ordinary course of business) or (c) any
other contract or agreement or amendment thereto that would be required to be
filed as an exhibit to a Form 10-K filed by NCC with the Commission as of the
date of this Agreement (collectively, the "NCC Contracts").  Neither NCC nor
any of NCC's subsidiaries is in default under any NCC Contracts, which default
is reasonably likely to have, either individually or in the aggregate, a
Material Adverse Effect and there has not occurred any event that with the
lapse of time or the giving of





                                      -14-
<PAGE>   20





notice or both would constitute such a default.  Neither NCC nor any of NCC's
subsidiaries is a party to, or is bound by, any collective bargaining
agreement, contract, or other agreement or understanding with a labor union or

or affecting NCC or any of NCC's subsidiaries which, if decided adversely to
NCC, would reasonably be expected to result in a Material Adverse Effect, nor

have, a Material Adverse Effect.

NCC Disclosure Letter, neither NCC nor any NCC subsidiary is a party to any 
written agreement or memorandum of understanding with, or a party to any

                                      -20-

of Company or any of the Company Subsidiaries under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, deed of trust,
license, lease, agreement or other instrument or obligation to which Company or
any Company Subsidiary is a party or to which they or any of their respective
properties or assets are subject, except for such violations, conflicts,
breaches, defaults, terminations, accelerations or creations of liens or other
encumbrances, which are set forth in the Company Disclosure Letter or which,
individually or in the aggregate, will not have a Material Adverse  Effect or
(c) require any consent, approval, authorization or permit of or from, or
filing with or notification to, any Governmental Entity, except (i) pursuant to
the Exchange Act and the Securities Act, (ii) filing the Certificate of Merger
and the Articles of Merger, (iii) filings required under the securities or blue

         4.7  REPORTS AND FINANCIAL STATEMENTS.  Since July 1, 1991, Company
and each Company Subsidiary have filed all reports, registrations and
statements, together with any required amendments thereto, that they were

14(a) of the Exchange Act, including, but not limited to Forms 10-K, Forms 10-Q
and proxy statements (the "Company Reports").  Company has previously furnished
or will promptly furnish NCC with true and complete copies of each of Company
annual reports on Form 10-K for fiscal years ending 1991 through 1993.  As of
their respective dates, Company Reports complied with the requirements of the
Commission and did not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstance under which they were made,
not misleading.  The audited consolidated financial statements and unaudited
interim financial statements of Company included in the Company Reports have
been prepared in accordance with generally accepted accounting principles
applied on a consistent basis (except as may be indicated therein or in the
notes thereto) and fairly present the financial position of Company and Company
Subsidiaries taken as a whole as at the  dates thereof and the consolidated
results of their operations and changes in cash flows for the periods then
ended subject, in the case of the unaudited interim financial statements, to
normal year-end and audit

adjustments and any other adjustments described therein.  There exist no
material liabilities of Company and its consolidated subsidiaries, contingent
or otherwise, except as disclosed in the Company Reports.  Company's reserve
for possible loan losses as shown in its Annual Report on Form 10-K for the
fiscal year ended September 30, 1993 was adequate, within the meaning of
generally accepted accounting principles and safe and sound banking practices.
         4.8  TAXES.  Company will promptly make available to NCC, upon request

Subsidiary have prepared in good faith and duly and timely filed, or caused to
be duly and timely filed, all federal, state, local and foreign income,
franchise, sales and other tax returns or reports required to be filed by them
on or before the date hereof, except to the extent that all failures to file,
taken together, would not have a Material Adverse Effect.  Company and each
Company Subsidiary have paid, or have made adequate provision or set up an
adequate accrual or reserve for the payment of, all taxes shown or required to
be shown to be owing on all such returns or reports, together with any
interest, additions or penalties related to any such taxes or to any open
taxable year or period.  Except as set forth in the Company Disclosure Letter,
neither Company nor any Company Subsidiary has consented to extend the statute
of limitations with respect to the assessment of any tax.  Except as set forth
in the Company Disclosure Letter, neither Company  nor any of the Company
Subsidiaries is a party to any action or proceeding, nor is any such action or
proceeding threatened, by any Governmental Entity in connection with the
determination, assessment or collection of any taxes, and no deficiency notices
or reports have been received by Company or any of the Company Subsidiaries in
respect of any material deficiencies for any tax, assessment, or government
charge.

Letter, all employee benefit, welfare, bonus, deferred compensation, pension,
profit sharing, stock option, employee stock ownership, consulting, severance,
or fringe benefit plans, formal or informal, written or oral and all trust

compliance with their terms and currently

comply, and have at all relevant times complied, in all material respects with
the applicable requirements of ERISA, the Code, and any other applicable laws.
Except as set forth in the Company Disclosure Letter, with respect to each
Company Employee Plan which is a pension plan (as defined in Section 3(2) of
ERISA):  (a) except for recent amendment(s) to the plans not materially
affecting the qualified status of the plans (which are disclosed in, and copies
of which are attached to, the Company Disclosure Letter), each pension plan as

Section 401(a) of the Code either has been determined by the IRS to be so
qualified or is the subject of a pending application for such determination
that was timely filed, (b) there is no accumulated funding deficiency (as
defined in Section 302 of ERISA and Section 412 of the Code) as of June 30,
1993 and, to the Company's knowledge thereafter, whether or not waived, and no
waiver of the minimum funding standards of such sections has been requested
from the IRS, (c) neither  Company nor any of the Company Subsidiaries has
provided, or is required to provide, security to any pension plan pursuant to
Section 401(a)(29) of the Code, (d) the fair market value of the assets of each

of the "benefit liabilities" within the meaning of Section 4001(a)(16) of ERISA
under such defined benefit plan as of June 30, 1993 and to the Company's
knowledge as of June 30, 1994, calculated on the basis of the actuarial
assumptions used in the most recent actuarial valuation for such defined
benefit plan as of the date hereof, (e) no reportable event described in
Section 4043 of ERISA for which the 30 day reporting requirement has not been
waived has occurred, (f) no defined benefit plan has been terminated, nor has
the Pension Benefit Guaranty Corporation ("PBGC") instituted proceedings to
terminate a defined benefit plan or to appoint a trustee or administrator of a
defined benefit plan, and no circumstances exist that constitute grounds under
Section 4042(a)(2) of ERISA entitling the PBGC to institute any such
proceedings and (g) no pension plan is a "multiemployer plan" within the
meaning of Section 3(37) of ERISA.  Neither Company nor any Company Subsidiary
has incurred any liability to the PBGC with respect to any "single-employer
plan" within the meaning of action 4001(a)(15) of ERISA currently or formerly
maintained by any entity considered one employer with it under Section 4001 of
ERISA or Section 414 of the Code, except for premiums all of which have been
paid when due.  Neither Company nor any of its subsidiaries has incurred any
withdrawal liability with respect to a multiemployer plan under

has any obligations for retiree health and life benefits under any Company

contract or agreement or amendment thereto that would be required to be filed
as an exhibit to a Form 10-K filed by Company with the Commission as of the

Company nor any Company Subsidiary is in default under any Company Contract,
which default is reasonably likely to have, either individually or in the
aggregate, a Material Adverse Effect, and there has not occurred any event that
with the lapse of time or the giving of notice or both would constitute such a
default.  Neither Company nor any Company Subsidiary is a party to, or is bound
by, nor is any person seeking to require the Company to enter into any
collective bargaining agreement, contract, or other agreement or understanding
with a labor union or labor organization, nor is Company or any Company

of, any shares of capital stock or any other securities of any of them or enter
into any arrangement or contract with respect to the purchase or voting of
shares of their capital stock, or adjust, split, combine or reclassify any of
their capital stock or other securities or make any other changes in their
capital structures.  Neither Company nor any Company subsidiary shall grant any
additional stock options under any Company Option Plans.
                 (d)  DIVIDENDS.  Company shall not and shall not permit any
Company Subsidiary to, declare, set aside, pay or make any dividend or other
distribution or payment (whether in cash, stock or property) with respect to,
or purchase or redeem, any shares of the capital stock of any of them other
than (a) regular quarterly cash dividends in an amount not to exceed $0.1275
per share of Company Common Stock for the September 30, 1994 quarter, not to
exceed $0.1325 per share of Company Common Stock for the December 31, 1994
quarter and not to exceed $0.1375 per share of Company Common Stock for the
March 31, 1995 quarter and any other quarter preceding the Closing Date and (b)
dividends paid by any Company Subsidiary to another Company Subsidiary or
Company with respect to its capital stock between the date hereof and the
Effective Time.  It is agreed by the parties hereto that they will cooperate to
assure that, during any quarter, there shall not be a duplication of nor
omission of payment of dividends to shareholders of Company.
                 (e)  EMPLOYEE PLANS, COMPENSATION, ETC.  Except as permitted
by Section 5.3(b) hereof, the Company shall not permit any Company Subsidiary
to adopt or amend (except as required by law) any bonus, profit sharing,
compensation, severance, termination, stock option, pension, retirement,
deferred compensation, employment, welfare benefit, or other employee benefit
agreements, trusts, plans or other arrangements for the benefit or welfare of
any director, officer, or employee, or (except for normal merit increases in
the ordinary course of business consistent with past practice) increase the
compensation or fringe benefits of any director, officer or employee or pay any
benefit not required by any existing plan or arrangement (including, without
limitation, the granting of stock options or stock appreciation rights) or take
any action





                                      -29-
<PAGE>   35





or grant any benefit not required under the terms of any existing agreements,
trusts, plans, funds or other such arrangements or enter into any contract,
agreement, commitment or arrangement to do any of the foregoing.
                 (f)  CERTAIN POLICIES.  Company shall use its best efforts to
modify and change its loan, litigation and real estate valuation policies and
practices (including loan classifications and level of reserves) prior to the
Effective Time so as to be consistent on a mutually satisfactory basis with
those of NCC and generally accepted accounting principles.  Company shall not
be required to modify or change any such policies or practices, however, until
(i) such time as NCC acknowledges that all conditions to its obligation to
consummate the Merger set forth in Sections 7.1 and 7.3 have been waived or
satisfied, and (ii) immediately prior to the Effective Time.  Company's
representations, warranties or covenants contained in this Agreement shall not
be deemed to be untrue or breached in any respect for any purpose as a
consequence of any such modifications or changes.
         5.3  EMPLOYEE MATTERS.  (a)  VESTED BENEFITS.  Surviving Corporation
agrees that it shall honor, on and after the Effective Time, without deduction,
counterclaims, interruptions or deferment (other than withholding under
applicable law), all vested benefits under all Company Employee Benefit Plans.
Nothing in this subsection shall preclude the alienation of vested benefits
under a Company Employee Benefit Plan pursuant to the terms of a Qualified
Domestic Relations Order within the meaning of Section 414(p) of the Code.
Surviving Corporation agrees that any deferred directors' fees held in an
account for Fred McClung or Stephen A. Kiley pursuant to the Unfunded Deferred
Compensation Plan for Directors of Kokomo (the "Plan") at the Effective Date
shall continue to be held under the Plan and to accrue interest as provided in
the Plan until paid out under the terms of the Plan.  In Mr. Kiley's case,
those fees shall become payable when he ceases to be an advisory director of
NCB.
                 (b)  EMPLOYMENT CONTRACTS.  Effective as of the Effective
Time, NCB will assume and NCC shall guarantee the employment agreements between
Kokomo and Robert J. Heltzel, Donald L. McCauley, Timothy A. Renie and James E.
Fritz for the balance of their terms and NCC will guarantee the obligations of
NCB resulting from such assumption, but, irrespective of continued employment,
such employment agreements shall not be renewed after the Closing.  The
employment agreements with Donald L. McCauley and James E. Fritz will be
extended





                                      -30-
<PAGE>   36





before the Effective Time, so that at the Effective Time the terms of the
employment agreements will end on the following dates for the following
employees:  Robert J. Heltzel (June 30, 1997); Donald L. McCauley (June 30,
1997); Timothy A. Renie (June 30, 1997); and James E.  Fritz (June 30, 1997).
                 (c)  OBLIGATIONS TO FORMER OFFICERS, DIRECTORS AND EMPLOYEES
OF FIRST FEDERAL SAVINGS AND LOAN ASSOCIATION OF PERU ("PERU").  Upon the
Effective Time, NCB shall assume, and NCC shall guarantee, all obligations of
Company and Kokomo to former officers, directors and employees of Peru, and
their spouses, set forth in the Merger Agreement dated September 8, 1993,
between Company, Kokomo and Peru concerning, among other things, the creation
and continuation of an advisory board of directors comprised of former Peru
directors until the death of such persons, the provision of group medical
insurance to former Peru advisory directors, directors, employees and retirees
and their spouses, and the provision of life insurance to former directors,
officers and employees of Peru for such periods and in such amounts and subject
to such terms as are provided for in that Merger Agreement, as though NCB were
a party thereto.
                 (d)      FRED MCCLUNG.  Upon consummation of the merger of
Kokomo into NCB, Fred McClung, an advisory director of Kokomo, shall be
appointed as an advisory director of NCB and shall remain such until December
31, 1995.  While he serves as such advisory director, he shall continue to
receive fees equal to 90% of the advisory director fees to be paid to existing
directors of the Company pursuant to subparagraph (e) hereof.
                 (e)      ADVISORY DIRECTORS.  Upon consummation of the merger
of Kokomo into NCB, each of the current directors of the Company shall be
appointed an advisory director of NCB's Logansport, Kokomo and Peru branch
operations and shall continue to serve in such capacity as long as they are
willing to do so, and as long as they are physically and mentally fit for such
purposes, until they reach age 70.  As such advisory directors, they will be
paid fees equal to those fees they are receiving as directors of Kokomo as of
the date hereof, subject to inflationary or merit increases which shall be made
at the discretion of NCB.
                 (f)  FINANCIAL INSTITUTIONS RETIREMENT PLAN.  (i)  Kokomo's
Financial Institutions Retirement Fund (the "Company Retirement Plan") will be
terminated and frozen as of the Effective Time, and all accrued benefits of
participants in that Company Retirement Plan shall





                                      -31-
<PAGE>   37





thereupon be fully vested and shall become payable at the times and in the
amounts provided for under that Plan.  All Company and Company Subsidiary
employees as of the Effective Time will be entitled to become eligible to
participate in NCC's retirement plan, receiving credit for past service with
the Company and Company Subsidiaries for vesting and eligibility purposes under
the NCC retirement plan.
                                        (ii)  There are twelve (12) employees
of Kokomo listed on the Disclosure Schedule who have attained age 55 and have
at least 15 years of service with the Company or Company Subsidiaries.  Except
as provided below, NCC agrees to provide such employees with a cash payment
equal to the actuarial equivalent present value of the increased benefits which
such employees would have received under the Company Retirement Plan had it
remained in effect for that three (3) year period following the Effective Time
(taking into account any cost of living payments which would have accrued with
respect to the increased payments provided for in the Company Retirement Plan).
Such actuarial equivalent present values shall be calculated using the
actuarial factors set forth under the NCC retirement plan and shall be
determined using such employees' actual compensation earned prior to the
Effective Time together with compensation at the rate in effect as of the
Effective Time projected for the three (3) year period.  Such amounts shall be
offset by similar actuarial equivalent present values of the projected accrued
benefit under the NCC retirement plan for such three (3) year period.  Any cash
payment under this paragraph (f)(ii) shall be paid as soon as practicable
following the Effective Time.  Notwithstanding anything in this paragraph to
the contrary, any additional benefit to be provided to Robert J. Heltzel or
Donald L. McCauley under this paragraph (f)(ii) may be provided through an
unfunded non-qualified retirement plan.
                 (g)      SEVERANCE.  Any employees of the Company or Kokomo
who are not retained in their current positions with the Company by NCC
following the Merger will, to the extent appropriate positions are available,
be offered, on the same basis as are employees of NCC generally, appropriate
employment opportunities at office and branch locations of NCB in the





                                      -32-
<PAGE>   38





State of Indiana, including, without limitation, those in Logansport and
Indianapolis.  Any Company or Kokomo employees not retained by NCC or its
subsidiaries following the Merger shall be entitled to severance pay pursuant
to NCC's severance pay program, a copy of which has been set forth in the NCC
Disclosure Letter.
                 (h)  GROUP INSURANCE.  Except as otherwise inconsistent with
any other provision herein, as of an appropriate time after the Effective Time,
Kokomo's group insurance program for health, life, dental, and accident and
disability insurance will be terminated and former Company or Company
Subsidiary employees, and present and (to the extent employed by Kokomo on a
full time basis on August 17, 1992) future retirees shall be eligible to
participate in NCC's comparable welfare benefits program.  To the extent that
the cost on the part of employees for such coverage is greater under the NCC
plan than under Kokomo's plan, NCC shall consider making appropriate salary
increases for former Company or Company Subsidiary employees to compensate for
such increased cost, assuming such increased salaries would be consistent and
comparable to those paid by NCC to its similarly situated employees.  To the
extent that the Company or Company Subsidiaries may be obligated to present or
future retirees under its "85 point rule" program as adopted by the Kokomo's
Board of Directors resolution on June 20, 1978 and as subsequently modified by
the Kokomo's Board of Directors resolution on August 18, 1992 and by its board
action on September 15, 1992, and as in effect at the Effective Time, NCC shall
be similarly obligated.  Otherwise, and except as otherwise provided in section
5.3(c) herein, NCC shall retain all rights to modify, change or terminate any
of its welfare benefits programs, assuming any such modification, charge or
termination applies to NCB employees generally.
                 (i)      THRIFT PLAN.  Kokom's Financial Institutions Thrift
Plan ("Thrift Plan") shall be terminated and frozen at the Effective Time or
shortly thereafter.  Upon the termination of the Thrift Plan, participant
accounts will become fully vested, and participants will have the opportunity
to roll their accounts into the NCC 401(k) Savings and Investment Plan (the
"NCC Savings Plan") or may elect to continue participation in the frozen Thrift
Plan.  The NCC





                                      -33-
<PAGE>   39





Savings Plan shall be amended to provide credit for past service for vesting
and eligibility purposes for such participants' employment with the Company and
Company Subsidiaries through the Effective Time.
                 (j)      STOCK PURCHASE PLAN.  The Company's Employee Stock
Purchase Plan will be terminated at the Effective Time or shortly thereafter,
and the payout of benefits shall be in accordance with its terms.
                 (k)  GENERAL.  Upon and after the Merger and except as
otherwise provided herein, Company and Company Subsidiary employees shall be
provided direct compensation and fringe benefits, including NCC's "Flex"
program and 401(k) Savings and Investment Plan, health and welfare benefits,
vacation benefits and severance arrangements on terms and conditions no less
favorable than those benefits provided to other employees of NCB.  Company and
Company Subsidiary employees shall be eligible for "core" benefits under the
NCC "Flex" program as of the date of the merger of Kokomo into NCB and for
"non-core" benefits on the first reasonably available enrollment date
thereafter occurring after the merger.
         5.4  ACCESS AND INFORMATION.  Upon reasonable notice, each of the
parties shall (and shall cause each of the parties' subsidiaries to) afford to
the other parties and their representatives (including, without limitation,
directors, officers and employees of the parties and their affiliates, and
counsel, accountants and other professionals retained) such  access during
normal business hours throughout the period prior to the Effective Time to the
books, records (including, without limitation, tax returns and work papers of
independent auditors), properties, personnel and to such other information as
any party may reasonably request; PROVIDED, HOWEVER, that no party shall be
required to provide access to any such information if the providing of such
access (i) would be reasonably likely, in the written opinion of counsel, to
result in the loss or impairment of any privilege generally recognized under
law with respect to such information or (ii) would be precluded by any law,
ordinance, regulation, judgment, order, decree, license or permit of any
Governmental Entity.  All information furnished by one party to any of the
others in connection with this Agreement or the transactions contemplated
hereby shall be kept confidential by such other party (and shall be used by it
only in connection with this Agreement and the transactions contemplated
thereby) except to the extent that such information already is known to such
other





                                      -34-
<PAGE>   40





party and (a) was when received from a source not known by the receiving party
to be under an obligation of confidentiality, (b) thereafter becomes lawfully
obtainable from other sources or (c) is required to be disclosed in any
non-confidential document filed with the Commission, the FRB, the Department of
Justice or any other agency or government entity.  In the event that the
transactions contemplated by this Agreement shall fail to be consummated, each
party shall promptly cause all copies of documents or extracts thereof
containing information and data as to another party hereto to be returned to
the party which furnished the same.
         5.5  CERTAIN FILINGS, CONSENTS AND ARRANGEMENTS.  NCC and Company
shall (a) as soon as practicable make any required filings and applications
required to be filed with Governmental Entities between the date of this
Agreement and the Effective Time, (b) cooperate with one another (i) in
promptly determining whether any other filings are required to be made or
consents, approvals, permits or authorizations are required to be obtained
under any other relevant federal, state or foreign law or regulation and (ii)
in promptly making any such filings, furnishing information required in
connection therewith and timely seeking to obtain any such consents, approvals,
permits or authorizations and (c) deliver to the other parties to this
Agreement copies of the publicly available portions of all such reports
promptly after they are filed.
         5.6  ENVIRONMENTAL SURVEY.  In the event NCC elects to conduct, or
have conducted on its behalf, an environmental review, study, survey or
assessment to verify the representations and warranties given by Company with
respect to Environmental Matters referred to in Section 4.19 of this Agreement,
such environmental review, study, survey or assessment shall be completed, and
all reports and findings related thereto shall be disclosed to Company within
45 days of the date hereof.  Nothing in this Section, however, is intended to
be a limit or a waiver of the representation and warranty contained in Section
4.19 and such representation and warranty shall be true at the date hereof and
at the Effective Time.
         5.7  INDEMNIFICATION AND INSURANCE.  From and after the Effective
Time, NCC will assume and honor any obligation as provided for and permitted by
applicable federal and state law the Company had immediately prior to the
Effective Time with respect to the indemnification of each person who is now,
or has been at any time prior to the date hereof or who becomes prior to the
Effective Time, a director or officer of Company or any Company Subsidiary or
was serving





                                      -35-
<PAGE>   41





at the request of Company as a director or officer of any domestic or foreign
corporation joint venture, trust, employee benefit plan or other enterprise
(collectively, the "Indemnitees") arising out of Company's Articles of
Incorporation or By-Laws or any indemnification (to the maximum extent
available thereunder and permitted by applicable law or regulation) against any
and all losses in connection with or arising out of any claim which is based
upon, arises out of or in any way relates to any actual or alleged act or
omission occurring at or prior to the Effective Time in the Indemnitee's
capacity as a director or officer (whether elected  or appointed), of Company
or any Company Subsidiary.  Moreover, indemnification of employees and
directors of the Company and its subsidiaries following the Effective Time will
be provided to the same extent it is provided to other persons working in
similar capacities for NCB following the Closing.  This Section 5.7 will be
construed as an agreement, as to which the Indemnitees are intended to be
third-party beneficiaries.  NCC shall for a period of at least two years
provide to the officers and directors of the Company directors and officers
insurance coverage (up to $20,000,000) with respect to claims not known by the
Company prior to the Effective Time but which arise from factors or events
which ocurred before the Effective Time.  Following the Effective Time, NCB
will provide any Company and Company Subsidiary employees who become officers
of NCB with the same directors and officers liability insurance coverage that
NCB provides to other officers of NCB.
         5.8  PUBLICITY.  The initial press release announcing this Agreement
shall be a joint press release and thereafter Company and NCC shall consult
with each other in issuing any press releases or otherwise making public
statements with respect to the transactions contemplated hereby and in making
any filings with any Governmental Entity or with any national securities
exchange with respect thereto.
         5.9  REGISTRATION STATEMENT.  NCC shall prepare and file the
Registration Statement with the Commission as soon as is reasonably practicable
and shall use all reasonable efforts to have the Registration Statement
declared effective by the Commission as promptly as practicable and to maintain
the effectiveness of such Registration Statement.  NCC shall also take any
action required to be taken under state blue sky or securities laws in
connection with the issuance of the NCC Common Stock pursuant to the Merger,
and Company  shall furnish NCC all information





                                      -36-
<PAGE>   42





concerning Company and the holders of its capital stock and shall take any
action as NCC may reasonably request in connection with any such action.
         5.10 STOCK EXCHANGE LISTINGS.  NCC shall use its best efforts to list
on the New York Stock Exchange, upon official notice of issuance, the NCC
Common Stock to be issued pursuant to the Merger.
         5.11 PROXY.  As soon as practicable after the date hereof, Company
shall prepare the Proxy Statement, file it with the Commission, respond to
comments of the Staff of the Commission, clear the Proxy Statement with the
Staff of the Commission and promptly thereafter mail the Proxy Statement to all
holders of shares of Company Common Stock.  NCC and Company shall cooperate
with each other in the preparation of the Proxy Statement.
         5.12 SHAREHOLDERS' MEETING.  Company shall take all action necessary,
in accordance with applicable law and its Articles of Incorporation and
By-Laws, to convene a meeting of the holders of Company Common Stock (the
"Company Meeting") as promptly as practicable for the purposes of considering
and taking action upon (a) a proposal to amend the Articles of Incorporation of
the Company to delete Article 11 (the "Articles Amendment") and (b) this
Agreement and the transactions contemplated hereby.  The Board of Directors of
Company shall recommend that the holders of the Company Common Stock (a) vote
in favor of and approve the adoption of the Articles Amendment and (b) vote in
favor and approve the Merger and this Agreement at the Company Meeting.
         5.13 TAX-FREE REORGANIZATION TREATMENT.  Neither NCC nor Company shall
intentionally take or cause to be taken any action, whether before or after the
Effective Time, which would disqualify the Merger as a "reorganization" within
the meaning of Section 368 of the Code.
         5.14 PROVISIONS OF SHARES.  NCC shall issue and provide the shares of
NCC Common Stock deliverable upon the conversion of the Company Common Stock
pursuant to this Agreement and the Plan of Merger, and will provide the cash to
be paid in lieu of fractional shares of NCC Common Stock as provided in
Subsection 2.3(g).

                              VI.  CLOSING MATTERS
                                   ---------------
         6.1  THE CLOSING.  Subject to satisfaction or waiver of all conditions
precedent set forth in Article VII of this Agreement, the closing ("Closing")
shall take place at NCC's corporate offices in Cleveland, Ohio or at such other
location as is mutually agreeable to the parties and on a date ("Closing Date")
which is the first business day after the later of:
                 (a) the first date on which the Merger may be consummated in
accordance with the approvals of any Governmental Entities, or
                 (b) the date the required approvals of Company's shareholders
have been obtained,
         If all conditions are determined to be satisfied in all material
respects (or are duly waived) at the Closing, the Closing shall be consummated
by the making of all necessary filings required by all Governmental Entities.
         6.2  DOCUMENTS AND CERTIFICATES.  NCC and Company shall use their
respective best efforts, on or prior to Closing, to execute and deliver all
such instruments, documents or certificates as may be necessary or advisable,
on the advice of counsel, for the consummation at the Closing of the
transactions contemplated by this Agreement or to cause the Effective Time,
subject to the consummation at the Closing, to occur as soon as practicable.

                                VII.  CONDITIONS
                                      ----------
         7.1  CONDITIONS TO EACH PARTY'S OBLIGATIONS TO EFFECT THE MERGER.  The
respective obligations of each party to effect the Merger shall be subject to
the fulfillment at or prior to the Effective Time of the following conditions:
                 (a)  The Articles Amendment, this Agreement and the
transactions contemplated hereby, and the Merger shall have been approved and
adopted by the requisite vote of the holders of Company Common Stock.
                 (b)  The NCC Common Stock issuable in the Merger shall have
been authorized for listing on the New York Stock Exchange, upon official
notice of issuance.





                                      -38-
<PAGE>   44





                 (c)  All authorizations, consents, orders or approvals of, and
all expirations of waiting periods imposed by, any Governmental Entity
(collectively, "Consents") which are necessary for the consummation of the
Merger, (other than immaterial Consents, the failure to obtain which would not
be materially adverse to the combined businesses of NCC, Company, NCC's
subsidiaries and Company Subsidiaries taken as a whole) shall have been
obtained or shall have occurred and shall be in full force and effect at the
Effective Time; PROVIDED, HOWEVER, that no such authorization, consent, order
or approval shall be deemed to have been received if it shall include any
conditions or requirements which would so reduce the economic or business
benefits of the transactions contemplated by this Agreement so as to render
inadvisable in the reasonable opinion of the Board of Directors of either NCC
or Company the consummation of the Merger.
                 (d)  The Registration Statement shall have become effective in
accordance with the provisions of the Securities Act.  No stop order suspending
the effectiveness of the Registration Statement shall have been issued by the
Commission and remain in effect.
                 (e)  No temporary restraining order, preliminary or permanent
injunction or other order by any federal or state court in the United States
which prevents or seeks to prevent the consummation of the Merger shall have
been issued and remain in effect.
                 (f)      Barnes & Thornburg, Counsel to Company, shall have
delivered to Company and NCC their opinion, dated the day of the Effective
Time, substantially to the effect that, on the basis of facts, representations
and assumptions set forth in such opinion which are consistent with the state
of facts existing at the Effective Time, the Merger will be treated for federal
income tax purposes as a reorganization within the meaning of Section 368(a) of
the Code and that, accordingly:  (i) no gain or loss will be recognized by NCC
or Company as a result of the Merger; (ii) no gain or loss will be recognized
by the shareholders of Company who exchange their shares of the Company Common
Stock solely for shares of NCC Common Stock pursuant to the Merger (except with
respect to cash received in lieu of a fractional share interest in NCC Common
Stock); (iii) the tax basis of the shares of NCC Common Stock received by
shareholders who exchange all of their shares of Company Common Stock solely
for shares of NCC Common Stock in the Merger will be the same as the tax basis
of the shares of Company Common Stock surrendered in exchange therefor (reduced
by any amount allocable to a





                                      -39-
<PAGE>   45





fractional share interest for which cash is received); and (iv) the holding
period of the shares of NCC Common Stock received in the Merger will include
the period during which the shares of Company Common Stock surrendered in
exchange therefor were held, provided such shares of Company Common Stock were
held as capital assets at the Effective Time.  In rendering such opinion,
counsel may require and rely upon representations contained in certificates of
officers of Company, NCC and others.
         7.2  CONDITIONS TO OBLIGATION OF COMPANY TO EFFECT THE MERGER.  The
obligation of Company to effect the Merger shall be subject to the fulfillment
or waiver at or prior to the Effective Time of the additional following
conditions:
                 (a)  NCC shall have performed in all material respects its
covenants contained in this Agreement required to be performed at or prior to
the Effective Time.
                 (b)  The representations and warranties of NCC contained in

representations and warranties set forth in Article 3 shall be true in all
material respects as of the Effective Time as if made at and as of such time,
except as expressly contemplated or permitted by this Agreement and except for
representations and warranties relating to a time or times other than the
Effective Time which were or will be true in all material respects at such time
or times.
                 (c)  NCC shall have furnished Company a Certificate dated the
date of the Closing, signed by the President or Chief Executive Officer and
Chief Financial Officer of NCC that, to the best of their knowledge and belief
after due inquiry, the conditions set forth in Subsections 7.2(a) and 7.2(b)
have been satisfied.
                 (d)   Company shall have received a fairness opinion from
McDonald & Company Securities, Inc. dated as of a date reasonably proximate to
the date of the proxy statement relating to the Merger and updated as of the
date of the Company Meeting stating that the Merger Consideration is fair to
the shareholders of the Company from a financial point of view.
         7.3  CONDITIONS TO OBLIGATION OF NCC TO EFFECT THE MERGER.  The

waiver at or prior to the Effective Time of the additional following

<PAGE>   46





                 (b)  The representations and warranties of Company contained
in this Agreement shall be true in all material respects when made and the
representations and warranties set forth in Article 4 shall be true in all
material respects as of the Effective Time as if made on and as of such time,

                             STOCK OPTION AGREEMENT

                 STOCK OPTION AGREEMENT, dated as of August ____, 1994, between
National City Corporation, a Delaware corporation ("Grantee"), and Central
Indiana Bancorp, an Indiana corporation ("Issuer").

                              W I T N E S S E T H:
                              - - - - - - - - - -

                 WHEREAS, Grantee and Issuer have entered into an Agreement and
Plan of Merger, dated July 25, 1994  ("Agreement"), which has been executed by
the parties hereto prior to this Stock Option Agreement; and

                 WHEREAS, as a condition to Grantee's entering into the
Agreement and in consideration therefor, Issuer has agreed to grant Grantee the
Option (as hereinafter defined):

                 NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements set forth herein and in the Agreement, the
parties hereto agree as follows:

                 1.  (a)  Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "Option") to purchase, subject to the terms hereof, up
to 326,000 fully paid and nonassessable shares of Common Stock, no par value
("Common Stock"), of Issuer at a price of $28.75 per share; PROVIDED, HOWEVER,
that in the event Issuer issues or agrees to issue any shares of Common Stock
(other than as permitted pursuant to the Company Stock Option Plans as provided
under the Agreement) at a price less than $28.75 per share (as adjusted
pursuant to subsection 5(b)), such price shall be equal to such lesser price
(such price, as adjusted if applicable, the "Option Price"); PROVIDED FURTHER
that in no event shall the number of shares for which this Option is
exercisable exceed 19.9% of the Issuer's issued and outstanding common shares
without giving effect to any shares subject or issued pursuant to the Option.
The number of shares of Common Stock that may be received upon the exercise of
the Option and the Option Price are subject to adjustment as herein set forth.

                 (b)  In the event that any additional shares of Common Stock
are issued or otherwise become outstanding after the date of this the Stock
Option Agreement (other 
<PAGE>   2
than pursuant to the Company Stock Option Plans as provided under the 
Agreement), the number of shares of Common Stock subject to the Option shall 
be increased so that, after such issuance, it equals 19.9% of the number of 
shares of Common Stock then issued and outstanding without giving effect to 
any shares subject or issued pursuant to the Option.  Nothing contained in this 
Section 1(b) or elsewhere in this Stock Option Agreement shall be deemed to 
authorize Issuer or Grantee to breach any provision of the Agreement.

                 2.  (a)  The Holder (as hereinafter defined) may exercise the
Option, in whole or part, if, but only if, both an Initial Triggering Event (as
hereinafter defined) and a Subsequent Triggering Event (as hereinafter defined)
shall have occurred prior to the occurrence of an Exercise Termination Event
(as hereinafter defined), PROVIDED that the Holder shall have sent the written
notice of such exercise (as provided in subsection (e) of this Section 2)
within 30 days following such Subsequent Triggering Event (or such later date
as provided in Section 10). Each of the following shall be an Exercise
Termination Event:  (i) immediately prior to the Effective Time of the Merger;
(ii) termination of the Agreement in accordance with the provisions thereof if
such termination occurs prior to the occurrence of an Initial Triggering Event;
or (iii) the passage of nine months after termination of the Agreement  if such
termination follows the occurrence of an Initial Triggering Event (PROVIDED
that if an Initial Triggering Event continues or another Initial Triggering
Event occurs beyond such termination, the Exercise Termination Event shall be
nine months from the expiration of the Last Triggering Event but in no event
more than 18 months after such termination).  The "Last Triggering Event" shall
mean the last Initial Triggering Event to occur.  The term "Holder" shall mean
the holder or holders of the Option.

                 (b)  The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                          (i)  Issuer or any of its subsidiaries (each an
         "Issuer Subsidiary"), without having received Grantee's prior written
         consent, shall have entered into an agreement to engage in an
         Acquisition Transaction (as hereinafter defined) with any person (the
         term "person" for purposes of this Stock Option Agreement having the
         meaning assigned thereto in Sections 3(a)(9) and 13(d)(3) of the
         Securities Exchange Act of 1934 (the "1934 Act"), and the rules and
         regulations thereunder) other than Grantee or any of its subsidiaries
         (each a "Grantee Subsidiary") or the Board of Directors of Issuer
         shall have recommended that the shareholders of Issuer approve or
         accept any Acquisition Transaction other than as contemplated by the
         Agreement.  For purposes of this Stock Option Agreement, "Acquisition
         Transaction" shall mean (x) a merger or consolidation, or any similar
         transaction, involving Issuer or Issuer's thrift subsidiary
         ("Significant


                                     -2-
<PAGE>   3
         Subsidiary"), (y) a purchase, lease or other acquisition of all or
         substantially all of the assets of Issuer or any Significant
         Subsidiary, or (z) a purchase or other acquisition (including by way
         of merger, consolidation, share exchange or otherwise) of securities
         representing 10% or more of the voting power of Issuer or Significant
         Subsidiary; (The term Acquisition Transaction specifically does not
         include any merger or consolidation among Issuer and/or Issuer
         Subsidiaries.)

                          (ii)  The Board of Directors of Issuer does not
         recommend that the shareholders of Issuer approve (a) the  amendment of
         the Articles of Incorporation of the Issuer to delete Article 11 or
         (b) the Agreement;

                          (iii)  Any person other than Grantee, any shareholder
         of Grantee who currently beneficially holds 10% or more of Grantee's
         outstanding shares of Common Stock, any Grantee Subsidiary or any
         Issuer Subsidiary acting in a fiduciary capacity shall have acquired
         beneficial ownership or the right to acquire beneficial ownership of
         10% or more of the outstanding shares of Common Stock (the term
         "beneficial ownership" for purposes of this Stock Option Agreement
         having the meaning assigned thereto in Section 13(d) of the 1934 Act,
         and the rules and regulations thereunder);

                          (iv)  Any person other than Grantee or any Grantee
         Subsidiary shall have made a BONA FIDE proposal to Issuer or its
         shareholders by public announcement or written communication that is
         or becomes the subject of public disclosure to engage in an
         Acquisition Transaction;

                           (v)  After a proposal is made by a third party to 
         Issuer or its shareholders to engage in an Acquisition Transaction, 
         Issuer shall have breached any covenant or obligation contained in 
         the Agreement and such breach (x) would entitle Grantee to terminate 
         the Agreement and (y) shall not have been cured prior to the Notice 
         Date (as defined below); or

                          (vi)  Any person other than Grantee or any Grantee
         Subsidiary, other than in connection with a transaction to which
         Grantee has given its prior written consent, shall have filed an
         application or notice with The Board of Governors of the Federal
         Reserve System (the "FRB") or other governmental authority or
         regulatory or administrative agency or commission, domestic or foreign
         (each, a "Government Entity"), for approval to engage in an
         Acquisition Transaction.

                 (c)  The term "Subsequent Triggering Event" shall mean either
of the following events or transactions occurring after the date hereof:

                 (i)  The acquisition  by any person of beneficial ownership of 
        15% or more of the then outstanding Common Stock other than by any 
        person who currently beneficially owns more than 15% of the outstanding 
        Common Stock; or

                (ii)  The occurrence of the Initial Triggering Event described 
        in clause (i) of subsection 2(b), except that the percentage referred 
        to in clause (z) shall be 15%.

                 (d)  Issuer shall notify Grantee promptly in writing of the
occurrence of any Initial Triggering Event or Subsequent Triggering Event
(together, a "Triggering Event"), it being understood that the giving of such
notice by Issuer shall not be a condition to the right of the Holder to
exercise the Option.

                 (e)  In the event the Holder is entitled to and wishes to
exercise the Option, it shall send to Issuer a written notice (the date of
which being herein referred to as the "Notice Date") specifying (i) the total
number of shares it will purchase pursuant to such exercise and (ii) a place
and date not earlier than three business days nor later than 60 business days
from the Notice Date for the closing of such purchase (the "Closing Date");
PROVIDED that if prior notification to or approval of the FRB or any other
Governmental Entity is required in connection with such purchase, the Holder
shall promptly file the required notice or application for approval and shall
expeditiously process the same and the period of time that otherwise would run
pursuant to this sentence shall run from the later of (x) the date on which any
required notification periods have expired or been terminated and (y) the date
on which such approvals have been obtained and any requisite waiting period or
periods shall have passed.  Any exercise of the option shall be deemed to occur
on the Notice Date relating thereto.

                 (f)  At the closing referred to in subsection (e) of this
Section 2, the Holder shall pay to Issuer the aggregate purchase price for the
shares of Common Stock purchased pursuant to the exercise of the Option in
immediately available funds by wire transfer to a bank account designated by
Issuer, PROVIDED that failure or refusal of Issuer to designate such a bank
account shall not preclude the Holder from exercising the Option.

                 (g)  At such closing, simultaneously with the delivery of
immediately available funds as provided in subsection (f) of this Section 2,
Issuer shall deliver to the Holder a certificate or certificates representing
the number of shares of Common Stock



                                     -4-
<PAGE>   5
purchased by the Holder and, if the Option should be exercised in part only, a
new Option evidencing the rights of the Holder thereof to purchase the balance
of the shares purchasable hereunder, and the Holder shall deliver to Issuer a
copy of this Stock Option Agreement and a letter agreeing that the Holder will
not offer to sell or otherwise dispose of such shares in violation of
applicable law or the provisions of this Stock Option Agreement.

                 (h)  Certificates for Common Stock delivered at a closing
hereunder shall be endorsed with a restrictive legend that shall read
substantially as follows:

         "The transfer of the shares represented by this certificate is subject
         to certain provisions of an agreement between the registered holder
         hereof and Issuer and to resale restrictions arising under the
         Securities Act of 1933, as amended.  A copy of such agreement is on
         file at the principal office of Issuer and will be provided to the
         holder hereof without charge upon receipt by Issuer of a written
         request therefor."

It is understood and agreed that:  (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act") in the above legend
shall be removed by delivery of substitute certificate(s) without such
reference if the Holder shall have delivered to Issuer a copy of a letter from
the staff of the Securities and Exchange Commission (the "SEC"), or an opinion
of counsel, in form and substance satisfactory to Issuer, to the effect that
such legend is not required for purposes of the 1933 Act; (ii) the reference to
the provisions of this Stock Option Agreement in the above legend shall be
removed by delivery of substitute certificate(s) without such reference if the
shares have been sold or transferred in compliance with the provisions of this
Stock Option Agreement and under circumstances that do not require the
retention of such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied.  In addition, such certificates shall bear any other legend as may
be required by law.

                 (i)  Upon the giving by the Holder to Issuer of the written
notice of exercise of the Option provided for under subsection (e) of this
Section 2 and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered
to the Holder.  Issuer shall pay all expenses, and any and all United States
Federal, state and local taxes and other charges that may be payable in
connection with



                                     -5-
<PAGE>   6
the preparation, issue and delivery of stock certificates under this Section 2
in the name of the Holder or its assignee, transferee or designee.

                 3.  Issuer agrees:  (i) that it shall at all times maintain,
free from preemptive rights, sufficient authorized but unissued or treasury
shares of Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock;
(ii) that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other voluntary
act, avoid or seek to avoid the observance or performance of any of the
covenants, stipulations or conditions to be observed or performed hereunder by
Issuer; (iii) promptly to take all action as may from time to time be required
(including (x) complying with all premerger notification, reporting and waiting
period requirements specified in 15 U.S.C. Section  l8a and regulations
promulgated thereunder and (y) in the event, under the Bank Holding Company Act
of 1956, as amended, or the Change in Bank Control Act of 1978, as amended, or
any state banking law, prior approval of or notice to the FRB or to any other
Governmental Entity is necessary before the Option may be exercised,
cooperating fully with the Holder in preparing such applications or notices and
providing such information to each such Governmental Entity as they may
require) in order to permit the Holder to exercise the Option and Issuer duly
and effectively to issue shares of Common Stock pursuant hereto; and (iv)
promptly to take all action provided herein to protect the rights of the Holder
against dilution.

                 4.  This Stock Option Agreement (and the Option granted
hereby) are exchangeable, without expense, at the option of the Holder, upon
presentation and surrender of this Stock Option Agreement at the principal
office of Issuer, for other agreements providing for Options of different
denominations entitling the holder thereof to purchase, on the same terms and
subject to the same conditions as are set forth herein, in the aggregate the
same number of shares of Common Stock purchasable hereunder.  The terms "Stock
Option Agreement" and "Option" as used herein include any Stock Option
Agreements and related options for which this Stock Option Agreement (and the
Option granted hereby) may be exchanged.  Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Stock Option Agreement, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Stock Option Agreement, if mutilated, Issuer will execute and deliver a
new Stock Option Agreement of like tenor and date.  Any such new Stock Option
Agreement executed and delivered shall constitute an additional contractual
obligation on the part of Issuer, whether or not the Stock Option Agreement so
lost, stolen, destroyed or mutilated shall at any time be enforceable by
anyone.



                                     -6-
<PAGE>   7
                 5.  In addition to the adjustment in the number of shares of
Common Stock that are purchasable upon exercise of the Option pursuant to
Section 1 of this Stock Option Agreement, the number of shares of Common Stock
purchasable upon the exercise of the Option shall be subject to adjustment from
time to time as provided in this Section 5.

                          (a)  In the event of any change in Common Stock by
reason of stock dividends, split-ups, mergers, recapitalizations, combinations,
subdivisions, conversions, exchanges of shares or the like, the type and number
of shares of Common Stock purchasable upon exercise hereof shall be
appropriately adjusted.

                          (b)  Whenever the number of shares of Common Stock
purchasable upon exercise hereof is adjusted as provided in this Section 5, the
Option Price shall be adjusted by multiplying the Option Price by a fraction,
the numerator of which shall be equal to the number of shares of Common Stock
purchasable prior to the adjustment and the denominator of which shall be equal
to the number of shares of Common Stock purchasable after the adjustment.

                 6.  Upon the occurrence of a Subsequent Triggering Event that
occurs prior to an Exercise Termination Event, Issuer shall, at the request of
Grantee delivered within 30 days (or such later date as may be provided
pursuant to Section 10) of such Subsequent Triggering Event (whether on its own
behalf or on behalf of any subsequent holder of this Option (or part thereof)
or any of the shares of Common Stock issued pursuant hereto), promptly prepare,
file and keep current a shelf registration statement under the 1933 Act
covering any shares issued and issuable pursuant to this Option and shall use
its best efforts to cause such registration statement to become effective and
remain current in order to permit the sale or other disposition of any shares
of Common Stock issued upon total or partial exercise of this option ("Option
Shares") in accordance with any plan of disposition requested by Grantee;
PROVIDED, HOWEVER, that Issuer may postpone filing a registration statement
relating to a registration request by Grantee under this Section 6 for a period
of time (not in excess of 180 days) if in its judgment such filing would
require the disclosure of material information that Issuer has a BONA FIDE
business purpose for preserving as confidential.  Issuer will use its best
efforts to cause such registration statement first to become effective and then
to remain effective for such period not in excess of 180 days from the day such
registration statement first becomes effective or such shorter time as may be
reasonably necessary to effect such sales or other dispositions.  Grantee shall
have the right to demand two such registrations.  The foregoing
notwithstanding, if, at the time of any request by Grantee for registration of
Option Shares as provided above, Issuer is in the process of registration with
respect to an



                                     -7-
<PAGE>   8
underwritten public offering of shares of Common Stock, and if in the good
faith judgment of the managing underwriter or managing underwriters, or, if
none, the sole underwriter or underwriters, of such offering the offering or
inclusion of the Holder's Option or Option Shares would interfere with the
successful marketing of the shares of Common Stock offered by Issuer, the
number of Option Shares otherwise to be covered in the registration statement
contemplated hereby may be reduced; PROVIDED, HOWEVER, that after any such
required reduction the number of Option Shares to be included in such offering
for the account of the Holder shall constitute at least 25% of the total number
of shares to be issued by the Holder and Issuer in the aggregate; PROVIDED
FURTHER, however, that if such reduction occurs, then the Issuer shall file a
registration statement for the balance as promptly as practical and no
reduction shall thereafter occur.  Each such Holder shall provide all
information reasonably requested by Issuer for inclusion in any registration
statement to be filed hereunder.  If requested by any such Holder in connection
with such registration, Issuer shall become a party to any underwriting
agreement relating to the sale of such shares, but only to the extent of
obligating itself in respect of representations, warranties, indemnities and
other agreements customarily included in such underwriting agreements.  Upon
receiving any request under this Section 6 from any Holder, Issuer agrees to
send a copy thereof to any other person known to Issuer to be entitled to
registration rights under this Section 6, in each case by promptly mailing the
same, postage prepaid, to the address of record of the persons entitled to
receive such copies.

                 7. (a)  Upon the occurrence of a Subsequent Triggering Event
that occurs prior to an Exercise Termination Event, (i) at the request of the
Holder, delivered within 30 days of the Subsequent Trigger Event (or such later
period as may be provided pursuant to Section 10), Issuer shall repurchase the
Option from the Holder at a price (the "Option Repurchase Price") equal to (x)
the amount by which (A) the market/offer price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised plus (y) Grantee's Out-of-Pocket Expenses (as defined below)
(to the extent not previously reimbursed) and (ii) at the request of the owner
of Option Shares from time to time (the "Owner"), delivered within 30 days of a
Subsequent Trigger Event (or such later period as may be provided pursuant to
Section 10), Issuer shall repurchase such number of the Option Shares from the
Owner as the Owner shall designate at a price (the "Option Share Repurchase
Price") equal to (x) the market/ offer price multiplied by the number of Option
Shares so designated plus (y) Grantee's Out-of-Pocket Expenses (to the extent
not previously reimbursed).  The term "Out-of-Pocket Expenses" shall mean
Grantee's reasonable out-of-pocket expenses incurred in connection with the
transactions contemplated by the Agreement, including, without limitation,
legal, accounting and investment banking fees. The term "market/offer price"
shall mean the highest of (i) the price per share of Common Stock at which a



                                     -8-
<PAGE>   9
tender offer or exchange offer therefor has been made after the date hereof,
(ii) the price per share of Common Stock to be paid by any third party pursuant
to an agreement with Issuer, (iii) the highest closing price for shares of
Common Stock within the 30-day period immediately preceding the date the Holder
gives notice of the required repurchase of this Option or the Owner gives
notice of the required repurchase of Option Shares, as the case may be, or (iv)
in the event of a sale of all or substantially all of Issuer's assets, the sum
of the price paid in such sale for such assets and the current market value of
the remaining assets of Issuer as determined by a nationally recognized
investment banking firm selected by the Holder or the Owner, as the case may
be, divided by the number of shares of Common Stock of Issuer outstanding at
the time of such sale.  In determining the market/offer price, the value of
consideration other than cash shall be determined by a nationally recognized
investment banking firm selected by the Holder or Owner, as the case may be,
whose determination shall be conclusive and binding on all parties.

                 (b)  The Holder or the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office, a copy of this Stock Option Agreement or certificates for
Option Shares, as applicable, accompanied by a written notice or notices
stating that the Holder or the Owner, as the case may be, elects to require
Issuer to repurchase this Option and/or the Option Shares in accordance with
the provisions of this Section 7.  As promptly as practicable, and in any event
within five business days after the surrender of the Option and/or certificates
representing Option Shares and the receipt of such notice or notices relating
thereto, Issuer shall deliver or cause to be delivered to the Holder the Option
Repurchase Price and/or to the Owner the Option Share Repurchase Price therefor
or the portion thereof that Issuer is not then prohibited under applicable law
and regulation from so delivering.

                 (c)  To the extent that Issuer is prohibited under applicable
law or regulation, or as a consequence of administrative policy, from
repurchasing the Option and/or the Option Shares in full, Issuer shall
immediately so notify the Holder and/or the Owner and thereafter deliver or
cause to be delivered, from time to time, to the Holder and/or the Owner, as
appropriate, the portion of the Option Repurchase Price and the Option Share
Repurchase Price, respectively, that it is no longer prohibited from
delivering, within five business days after the date on which Issuer is no
longer so prohibited; PROVIDED, HOWEVER, that if Issuer at any time after
delivery of a notice of repurchase pursuant to subsection (b) of this Section 7
is prohibited under applicable law or regulation, or as a consequence of
administrative policy, from delivering to the Holder and/or the Owner, as
appropriate, the Option Repurchase Price and the Option Share Repurchase Price,
respectively, in full (and Issuer hereby undertakes to use its best efforts to
obtain all required regulatory and legal approvals and to file any required
notices as



                                     -9-
<PAGE>   10
promptly as practicable in order to accomplish such repurchase), the Holder or
Owner may revoke its notice of repurchase of the Option or the Option Shares
either in whole or to the extent of the prohibition, whereupon, in the latter
case, Issuer  shall promptly (i) deliver to the Holder and/or the Owner, as
appropriate, that portion of the Option Purchase Price or the Option Share
Repurchase Price that Issuer is not prohibited from delivering; and (ii)
deliver, as appropriate, either (A) to the Holder, a new Stock Option Agreement
evidencing the right of the Holder to purchase that number of shares of Common
Stock obtained by multiplying the number of shares of Common Stock for which
the surrendered Stock Option Agreement was exercisable at the time of delivery
of the notice of repurchase by a fraction, the numerator of which is the Option
Repurchase Price less the sum of (x) the portion thereof theretofore delivered
to the Holder and (y) Out-of-Pocket Expenses and the denominator of which is
the Option Repurchase Price less Out-of-Pocket Expenses, or (B) to the Owner, a
certificate for the Option Shares it is then so prohibited from repurchasing,
assuming that the portion of the Option Share Repurchase Price theretofore
delivered is first applied to the payment of Out-of-Pocket Expenses and then to
the repurchase of Option Shares.

                 8.  (a)  In the event that prior to an Exercise Termination
Event, Issuer shall enter into an agreement (i) to consolidate or merge with
any person, other than Grantee or one of its subsidiaries, and shall not be the
continuing or surviving corporation of such consolidation or merger, (ii) to
permit any person, other than Grantee or one of its subsidiaries, to merge into
Issuer and Issuer shall be the continuing or surviving corporation, but, in
connection with such merger, the then outstanding shares of Common Stock shall
be changed into or exchanged for stock or other securities of any other person
or cash or any other property or the then outstanding shares of Common Stock
shall after such merger represent less than 50% of the outstanding shares and
share equivalents of the merged company, or (iii) to sell or otherwise transfer
all or substantially all of its assets to any person, other than Grantee or one
of its subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provision so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set
forth herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of the Holder, of either (x) the Acquiring
Corporation (as hereinafter defined) or (y) any person that controls the
Acquiring Corporation.

                 (b)  The following terms have the meanings indicated:

                          (1) "Acquiring Corporation" shall mean (i) the
         continuing or surviving corporation of a consolidation or merger with
         Issuer (if other than Issuer), (ii) Issuer in a merger in which Issuer
         is the continuing or surviving person, and (iii) the transferee of all
         or substantially all of Issuer's assets.



                                     -10-
<PAGE>   11
                          (2) "Substitute Common Stock" shall mean the common
         stock to be issued by the issuer of the Substitute Option upon
         exercise of the Substitute Option.

                          (3) "Assigned Value" shall mean the market/offer 
         price, as defined in Section 7.

                          (4) "Average Price" shall mean the average closing
         price of a share of the Substitute Common Stock for the one year
         immediately preceding the consolidation, merger or sale in question,
         but in no event higher than the closing price of the shares of
         Substitute Common Stock on the day preceding such consolidation,
         merger or sale; PROVIDED, that if Issuer is the issuer of the
         Substitute Option, the Average Price shall be computed with respect to
         a share of common stock issued by the person merging into Issuer or by
         any company which controls or is controlled by such person, as the
         Holder may elect.

                 (c)  The Substitute Option shall have the same terms as the
Option, provided, that if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to the Holder.  The issuer of the Substitute
Option shall also enter into an agreement with the then Holder or Holders of
the Substitute Option in substantially the same form as this Stock Option
Agreement, which shall be applicable to the Substitute Option.

                 (d)  The Substitute Option shall be exercisable for such
number of shares of Substitute Common Stock as is equal to the Assigned Value
multiplied by the number of shares of Common Stock for which the Option is then
exercisable, divided by the Average Price.  The exercise price of the
Substitute Option per share of Substitute Common Stock shall then be equal to
the Option Price multiplied by a fraction, the numerator of which shall be the
number of shares of Common Stock for which the Option is then exercisable and
the denominator of which shall be the number of shares of Substitute Common
Stock for which the Substitute Option is exercisable.

                 (e)  In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.
In the event that the Substitute Option would be exercisable for more than
19.9% of the shares of Substitute Common Stock outstanding prior to exercise
but for this clause (e), the issuer of the Substitute Option (the "Substitute
Option Issuer") shall make a cash payment to the Holder equal to the excess of
(i) the value of the Substitute Option without giving effect



                                     -11-
<PAGE>   12
to the limitation in this clause (e) over (ii) the value of the Substitute
Option after giving effect to the limitation in this clause (e).  This
difference in value shall be determined by a nationally recognized investment
banking firm selected by the Holder.

                 (f)  Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any
person that controls the Acquiring Corporation assume in writing all the
obligations of Issuer hereunder.

                 9.  (a)  At the request of the holder of the Substitute Option
(the "Substitute Option Holder"), the issuer of the Substitute Option (the
"Substitute Option Issuer") shall repurchase the Substitute Option from the
Substitute Option Holder at a price (the "Substitute Option Repurchase Price")
equal to (x) the amount by which (i) the Highest Closing Price (as hereinafter
defined) exceeds (ii) the exercise price of the Substitute Option, multiplied
by the number of shares of Substitute Common Stock for which the Substitute
Option may then be exercised plus (y) Grantee's Out-of-Pocket Expenses (to the
extent not previously reimbursed), and at the request of the owner (the
"Substitute Share Owner") of shares of Substitute Common Stock (the "Substitute
Shares"), the Substitute Option issuer shall repurchase the Substitute Shares
at a price (the "Substitute Share Repurchase Price") equal to (x) the Highest
Closing Price multiplied by the number of Substitute Shares so designated plus
(y) Grantee's Out-of-Pocket Expenses (to the extent not previously reimbursed).
The term "Highest Closing Price" shall mean the highest closing price for
shares of Substitute Common Stock within the 30-day period immediately
preceding the date the Substitute Option Holder gives notice of the required
repurchase of the Substitute Option or the Substitute Share Owner gives notice
of the required repurchase of the Substitute Shares, as applicable.

                 (b)  The Substitute Option Holder or the Substitute Share
Owner, as the case may be, may exercise its respective right to require the
Substitute Option Issuer to repurchase the Substitute Option and the Substitute
Shares pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal office, the agreement for such
Substitute Option (or, in the absence of such an agreement, a copy of this
Stock Option Agreement) and certificates for Substitute Shares accompanied by a
written notice or notices stating that the Substitute Option Holder or the
Substitute Share Owner, as the case may be, elects to require the Substitute
Option Issuer to repurchase the Substitute Option and/or the Substitute Shares
in accordance with the provisions of this Section 9.  As promptly as
practicable, and in any event within five business days after the surrender of
the Substitute Option and/or certificates representing Substitute Shares and
the receipt of such notice or notices relating thereto, the Substitute Option
Issuer shall deliver or cause to be delivered to the Substitute Option Holder
the Substitute Option



                                     -12-
<PAGE>   13
Repurchase Price and/or to the Substitute Share Owner the Substitute Share
Repurchase Price therefor or the portion thereof which the Substitute Option
Issuer is not then prohibited under applicable law and regulation from so
delivering.

                 (c)  To the extent that the Substitute Option Issuer is
prohibited under applicable law or regulation, or as a consequence of
administrative policy, from repurchasing the Substitute Option and/or the
Substitute Shares in part or in full, the Substitute Option Issuer shall
immediately so notify the Substitute Option Holder and/or the Substitute Share
Owner and thereafter deliver or cause to be delivered, from time to time, to
the Substitute Option Holder and/or the Substitute Share Owner, as appropriate,
the portion of the Substitute Share Repurchase Price, respectively, which it is
no longer prohibited from delivering, within five business days after the date
on which the Substitute Option Issuer is no longer so prohibited; PROVIDED,
HOWEVER, that if the Substitute Option Issuer is at any time after delivery of
a notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable law or regulation, or as a consequence of administrative
policy, from delivering to the Substitute Option Holder and/or the Substitute
Share Owner, as appropriate, the Substitute Option Repurchase Price and the
Substitute Share Repurchase Price, respectively, in full (and the Substitute
Option Issuer shall use its best efforts to receive all required regulatory and
legal approvals as promptly as practicable in order to accomplish such
repurchase), the Substitute Option Holder or Substitute Share Owner may revoke
its notice of repurchase of the Substitute Option or the Substitute Shares
either in whole or to the extent of the prohibition, whereupon, in the latter
case, the Substitute Option Issuer shall promptly (i) deliver to the Substitute
Option Holder or Substitute Share Owner, as appropriate, that portion of the
Substitute Option Repurchase Price or the Substitute Share Repurchase Price
that the Substitute Option Issuer is not prohibited from delivering; and (ii)
deliver, as appropriate, either (A) to the Substitute Option Holder, a new
Substitute Option evidencing the right of the Substitute Option Holder to
purchase that number of shares of the Substitute Common Stock obtained by
multiplying the number of shares of the Substitute Common Stock for which the
surrendered Substitute Option was exercisable at the time of delivery of the
notice of repurchase by a fraction, the numerator of which is the Substitute
Option Repurchase Price less the sum of (x) the portion thereof theretofore
delivered to the Substitute Option Holder and (y) Out-of-Pocket Expenses and
the denominator of which is the Substitute Option Repurchase Price less
Out-of-Pocket Expenses, or (B) to the Substitute Share Owner, a certificate for
the Substitute Option Shares it is then so prohibited from repurchasing,
assuming that the portion of the Substitute Share Repurchase Price theretofore
delivered is first applied to the payment of Out-of-Pocket Expenses and then to
the repurchase of Substitute Shares.

<PAGE>   14
                 10.  The 30-day period for exercise of certain rights under
Sections 2, 6, 7 and 12 shall be extended:  (i) to the extent necessary to
obtain all regulatory approvals for the exercise of such rights, and for the
expiration of all statutory waiting periods; and (ii) to the extent necessary
to avoid liability under Section 16(b) of the 1934 Act by reason of such
exercise.

                 11.  Issuer hereby represents and warrants to Grantee as
follows:

                 (a)  Except to the extent that the exercise of all or a
portion of this option may be prohibited by Article 11 of the Issuer's Articles
of Incorporation, Issuer has full corporate power and authority to execute and
deliver this Stock Option Agreement and to consummate the transactions
contemplated hereby.  Except to the extent that the exercise of all or a
portion of this option may be prohibited by Article 11 of the Issuer's Articles
of Incorporation, The execution and delivery of this Stock Option Agreement and
the consummation of the transactions contemplated hereby have been duly and
validly authorized by the Board of Directors of Issuer and no other corporate
proceedings on the part of Issuer are necessary to authorize this Stock Option
Agreement or to consummate the transactions so contemplated.  This Stock Option
Agreement has been duly and validly executed and delivered by Issuer.  This
Stock Option Agreement is the valid and legally binding obligation of Issuer.

                 (b)  Issuer has taken all necessary corporate action to
authorize and reserve and to permit it to issue, and at all times from the date
hereof through the termination of this Stock Option Agreement in accordance
with its terms will have reserved for issuance upon the exercise of the Option,
that number of shares of Common Stock equal to the maximum number of shares of
Common Stock at any time and from time to time issuable hereunder, and all such
shares, upon issuance pursuant hereto, will be duly authorized, validly issued,
fully paid, nonassessable, and will be delivered free and clear of all claims,
liens, encumbrances and security interests and not subject to any preemptive
rights.

                 12.  Neither of the parties hereto may assign any of its
rights and obligations under this Stock Option Agreement or the Option created
hereunder to any other person, without the express written consent of the other
party, except that in the event a Subsequent Triggering Event shall have
occurred prior to an Exercise Termination Event, Grantee, subject to the
express provisions hereof, may assign in whole or in part its rights and
obligations hereunder within 30 days following such Subsequent Triggering Event
(or such later period as may be provided pursuant to Section 10); PROVIDED,
HOWEVER, that until the date 30 days following the date at which the FRB
approves an application by Grantee under the Bank Holding Company Act to
acquire the shares of Common Stock subject to the Option, Grantee may not
assign its



                                     -14-

rights under the Option except in (i) a widely dispersed public distribution,
(ii) a private placement in which no one party acquires the right to purchase
in excess of 2% of the voting shares of Issuer, (iii) an assignment to a single
party (E.Q., a broker or investment banker) for the purpose of conducting a
widely dispersed public distribution on Grantee's behalf, or (iv) any other
manner approved by the FRB.

                 13.  Each of Grantee and Issuer will use its best efforts to
make all filings with, and to obtain consents of, all third parties and
Governmental Entities necessary to the consummation of the transactions
contemplated by this Stock Option Agreement, including without limitation
making application to list the shares of Common Stock issuable hereunder on the
New York Stock Exchange upon official notice of issuance and applying to the
FRB under the Bank Holding Company Act for approval to acquire the shares
issuable hereunder.

                 14.  Notwithstanding anything to the contrary herein, in the
event that the Holder or Owner or any affiliate (as defined in Rule 12b-2 of
the rules and regulations under the 1934 Act) thereof is a person making an
offer or proposal to engage in an Acquisition Transaction (other than the
Merger), then (i) in the case of a Holder or any affiliate thereof, the Option
held by it shall immediately terminate and be of no further force or effect,
and (ii) in the case of an Owner or any affiliate thereof, the Option Shares
held by it shall be immediately repurchasable by Issuer at the Option Price.

                 15.  The parties hereto acknowledge that damages would be an
inadequate remedy for a breach of this Stock Option Agreement by either party
hereto and that the obligations of the parties shall hereto be enforceable by
either party hereto through injunctive or other equitable relief.

                 16.  If any term, provision, covenant or restriction contained
in this Stock Option Agreement is held by a court or a federal or state
regulatory agency of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions and covenants and
restrictions contained in this Stock Option Agreement shall remain in full
force and effect, and shall in no way be affected, impaired or invalidated.  If
for any reason such court or regulatory agency determines that the Holder is
not permitted to acquire, or Issuer is not permitted to repurchase pursuant to
Section 7, the full number of shares of Common Stock provided in Section 1(a)
hereof (as adjusted pursuant to Section 1(b) or 5 hereof), it is the express
intention of Issuer to allow the Holder to acquire or to require Issuer to
repurchase such lesser number of shares as may be permissible, without any
amendment or modification hereof.

                 17.  All notices, requests, claims, demands and other

mail (postage prepaid, return receipt requested) at the respective addresses of
the parties set forth in the Agreement.

                 18.  This Stock Option Agreement shall be governed by and
construed in accordance with the laws of the State of Indiana, regardless of
the laws that might otherwise govern under applicable principles of conflicts
of laws thereof.

                 19.  This Stock Option Agreement may be executed in two or
more counterparts, each of which shall be deemed to be an original, but all of
which shall constitute one and the same agreement.

                 20.  Except as otherwise expressly provided herein, each of
the parties hereto shall bear and pay all costs and expenses incurred by it or
on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own financial consultants, investment
bankers, accountants and counsel.

                 21.  Except as otherwise expressly provided herein or in the
Agreement, this Stock Option Agreement contains the entire agreement between
the parties with respect to the transactions contemplated hereunder and
supersedes all prior arrangements or understandings with respect thereof,
written or oral.  The terms and conditions of this Stock Option Agreement shall
inure to the benefit of and be binding upon the parties hereto and their
respective successors and permitted assigns.  Nothing in this Stock Option
Agreement, expressed or implied, is intended to confer upon any party, other
than the parties hereto, and their respective successors except as assigns, any
rights, remedies, obligations or liabilities under or by reason of this Stock
Option Agreement, except as expressly provided herein.

                 22.  Terms used in this Stock Option Agreement and not defined
herein but defined in the Agreement shall have the meanings assigned thereto in
the Agreement.
