Dear Shareholder:
 
     The Board of Directors cordially invites you to attend a Special Meeting of
Shareholders of Central Indiana Bancorp ("CIB") to be held at the Kokomo Country
Club, 1801 Country Club Drive, Kokomo, Indiana, on Tuesday, December 27, 1994,
commencing at 4:00 p.m. Eastern Standard Time.
 
     At this important meeting, you will be asked to consider and vote on (i) an
amendment to the Articles of Incorporation of CIB to repeal Article 11 thereof
which prohibits the acquisition of beneficial ownership of more than 10% of any
class of equity security of CIB (the "Articles Amendment") and (ii) the
Agreement and Plan of Merger (the "Merger Agreement") providing for a merger
transaction (the "Merger") whereby CIB will be merged with and into National
City Corporation, a Delaware corporation ("NCC"), and the Merger provided for
therein.
 
     In the Merger, you will receive 1.08 shares of NCC Common Stock, $4.00 par
value per share, ("NCC Common") plus cash in lieu of fractional shares, for each
of your shares of Common Stock of CIB, without par value ("CIB Common"). The
transaction is intended to be free from federal income taxation to the extent
you receive solely NCC Common in exchange for your shares of CIB Common (except
cash in lieu of fractional shares).
 
     THE CIB BOARD OF DIRECTORS HAS APPROVED THE ARTICLES AMENDMENT AND THE
MERGER AGREEMENT AND THE MERGER PROVIDED FOR THEREIN AS BEING IN THE BEST
INTERESTS OF CIB AND ITS SHAREHOLDERS AND RECOMMENDS THAT SHAREHOLDERS VOTE FOR
APPROVAL OF THE ARTICLES AMENDMENT, THE MERGER AGREEMENT AND THE MERGER. The
Merger presents you with the opportunity to participate in what we believe will
be a more diversified and more competitive institution.
 
     A Notice of Special Meeting and a Prospectus and Proxy Statement containing
detailed information concerning the Merger are attached. We urge you to
carefully review these materials before completing the enclosed proxy card.
 
     IT IS A CONDITION TO THE CONSUMMATION OF THE MERGER THAT THE MERGER
AGREEMENT AND THE MERGER RECEIVE THE APPROVAL OF THE HOLDERS OF A MAJORITY OF
THE OUTSTANDING SHARES OF CIB COMMON. A FAILURE TO VOTE WILL HAVE THE SAME
EFFECT AS A VOTE AGAINST THE MERGER AGREEMENT AND THE MERGER. Accordingly, it is
important that your shares be represented at the Special Meeting whether or not
you plan to attend the Special Meeting in person. Therefore, we urge you to
complete, sign and date the enclosed proxy card and return it in the
accompanying pre-addressed envelope, which requires no postage if mailed within
the United States. You are, of course, welcome to attend the Special Meeting and
to vote your shares in person.

                                    SUMMARY
 
     The following is a summary of certain information with respect to matters
to be considered at a Special Meeting of Shareholders of CIB and is not intended
to be a complete statement of all material facts regarding the matters to be
considered at that meeting. It is qualified in its entirety by reference to more
detailed information contained elsewhere in this Prospectus and Proxy Statement
(hereinafter sometimes referred to as this or the "Proxy Statement") or
incorporated by reference in this Proxy Statement, the accompanying appendices
and the documents referred to herein.
 
PARTIES TO THE MERGER
 
     CIB. CIB is a registered savings and loan holding company under the Home
Owners' Loan Act of 1933, as amended (the "HOLA"), and is incorporated under the
laws of the State of Indiana. As of September 30, 1994, CIB owned all of the
outstanding stock of one federal savings bank in Indiana, and through this
savings bank operated five (5) offices in Indiana. CIB, through its federal
savings bank and other subsidiaries, offers a broad range of lending, deposit
and other financial services to retail and commercial customers in its market
areas. At September 30, 1994, CIB, its affiliate federal savings bank and other
subsidiary had consolidated total assets of $244 million and consolidated total
deposits of $201 million. See "SUMMARY -- Selected Financial Data"; "SUMMARY --
Comparative Per Share Data"; "PRO FORMA COMBINED CONSOLIDATED FINANCIAL
INFORMATION (UNAUDITED) and "INFORMATION ABOUT CIB". The principal office of CIB
is located at 200 West Mulberry Street, P.O. Box 730, Kokomo, Indiana
46903-0730, and its telephone number is (317) 457-5552.
 
     NCC.  NCC is a registered multi-bank holding company under the Bank Holding
Company Act of 1933, as amended (the "BHCA") and is incorporated under the laws
of the State of Delaware. As of September 30, 1994, NCC owned substantially all
of the outstanding stock of 10 commercial banks in Ohio, Kentucky and Indiana,
and through these banks, operated 610 offices. NCC, through its subsidiaries,
offers a wide range of general commercial banking and other financial services,
such as credit card, retail payment and airline ticket processing, brokerage
services, trust and investment management, leasing, merchant and mortgage
banking, public finance, venture capital, small business and community
investment and credit life insurance. At September 30, 1994, NCC, its affiliate
banks and other subsidiaries had consolidated total assets of $31 billion and
consolidated total deposits of $23 billion. See "SUMMARY -- Selected Financial
Data"; "SUMMARY -- Comparative Per Share Data"; "PRO FORMA COMBINED CONSOLIDATED
FINANCIAL INFORMATION (UNAUDITED) and "INFORMATION ABOUT NCC"." The principal
office of NCC is located at 1900 East Ninth Street, Cleveland, Ohio 44114, and
its telephone number is (216) 575-2000.
 
REASONS FOR THE MERGER
 
     After exploring various other strategic alternatives, including the
possibility of remaining independent and merging with other institutions, CIB
believes that the Merger offers the greatest potential for achieving long-term
value for CIB shareholders while providing superior banking services to its
customers.
 
     Since establishing a major presence in Indiana by acquiring Merchants
National Corporation in 1992, NCC has sought to enhance its Indiana network
through internal growth and select acquisitions. Both NCC and CIB believe that
the Merger will result in a combined entity which will be greater than the sum
of NCC and CIB standing alone.
 
     See "MERGER -- Background of and Reasons for the Merger -- CIB" and "--
Background of and Reasons for the Merger -- NCC."
 
TERMS OF THE MERGER
 
     Pursuant to the Agreement and Plan of Merger dated July 25, 1994 by and
between CIB and NCC (the "Merger Agreement"), CIB will merge with and into NCC
and NCC will be the surviving or resulting corporation (the "Merger"). A copy of
the Merger Agreement is attached hereto as Appendix A and hereby incorporated
herein. At the time the Merger becomes effective (the "Effective Time"), each
outstanding share of CIB Common (except shares held by CIB, NCC or any of their
direct or indirect wholly owned subsidiaries
 
                                        6
<PAGE>   10
 
(other than shares of CIB Common held in trust accounts, managed accounts or in
any similar manner as trustee or in a fiduciary capacity or acquired in
satisfaction of debts previously contracted)) will be converted into the right
to receive 1.08 shares of NCC Common.
 
     No fractional shares of NCC Common will be issued in the Merger. In lieu
thereof, each holder of CIB Common who otherwise would have been entitled to a
fractional share of NCC Common will receive cash in an amount determined by
multiplying the fractional share interest to which such holder would otherwise
be entitled by the average of the per share closing price on the NYSE of NCC
Common for the 20 consecutive trading days ending at the end of the fifth
trading day immediately preceding the Closing Date (the "Market Price").
 
     The closing price of NCC Common on the NYSE on November   , 1994 was
$       (which is the equivalent of $       for 1.08 shares of NCC Common). In
the event the Market Price of NCC Common is less than $24.50 and the number
obtained by dividing the Market Price of NCC Common by $26.375 (the closing
price of NCC Common on the NYSE on July 22, 1994) is less than the number
obtained by dividing the Final Index Price by the Initial Index Price (as such
terms are defined in "MERGER -- Waiver; Amendment; Termination") and subtracting
0.10 from the quotient thereof, CIB may terminate the Merger Agreement. The
Initial Index Price will be the weighted average (weighted as described in
"MERGER -- Waiver; Amendment; Termination") of the closing prices on July 22,
1994 of the common stock of the 49 bank holding companies described on page 25
of this Proxy Statement. The Final Index Price will be the weighted average
(weighted as described in "MERGER -- Waiver; Amendment; Termination") of the
average of the daily closing sale prices of the common stock of each of such
bank holding companies during the period of 20 consecutive trading days ending
at the end of the fifth trading day immediately preceding the Closing Date. See
"MERGER -- Waiver; Amendment; Termination."
 
     Following the Merger, the directors and officers of NCC at the Effective
Time will continue as the directors and officers of NCC.
 
CONDITIONS; TERMINATION; AMENDMENTS
 
     Consummation of the Merger is subject to satisfaction of a number of
conditions, including (a) adoption by the shareholders of CIB of the proposal to
amend the Articles of Incorporation of CIB to delete Article 11 (the "Articles
Amendment"), (b) approvals by the shareholders of CIB of the Merger Agreement
and the Merger provided for therein, (c) approval by certain federal and state
banking authorities, (d) authorization for listing on the NYSE of the NCC Common
issuable in the Merger, (e) the issuance by the Commission of an order declaring
the Registration Statement effective, (f) the receipt by NCC and CIB of the
opinion of Barnes & Thornburg, special counsel to CIB, substantially to the
effect that the Merger will be treated for federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), and (h) the non-existence of a restraining
order, preliminary or permanent injunction or other order by any federal or
state court in the United States preventing the consummation of the Merger.
Substantially all of the conditions to consummation of the Merger (other than
required shareholder or regulatory approvals) may be waived, in whole or in
part, by the party for whose benefit they have been created, without the
approval of the shareholders of CIB or stockholders of NCC. In addition, the
Agreement may be terminated under certain circumstances, and such termination
would not require stockholder or shareholder approval. The Merger Agreement may
be amended or supplemented upon the written agreement of NCC and CIB at any
time, provided that no amendment may be made after any shareholder adoption of
the Merger Agreement which reduces or changes the form of the merger
consideration without further shareholder approval. See "MERGER -- Conditions to
the Merger" and "MERGER -- Waiver; Amendment; Termination."
 
REGULATORY APPROVALS
 
     In order for the Merger to be consummated, approval must be obtained from
The Board of Governors of the Federal Reserve System ("FRB"). The Merger may not
be consummated until the 30th day after FRB approval is received. Application
requesting such approval has been filed with the FRB. The FRB approved the
Merger on October 20, 1994. See "MERGER -- Regulatory Approvals."

THE SPECIAL MEETING
 
     CIB. The Special Meeting of Shareholders of CIB will be held on December
27, 1994, at the Kokomo Country Club, 1801 Country Club Drive, Kokomo, Indiana
commencing at 4:00 p.m., Eastern Standard Time. The Board of Directors of CIB
has fixed the close of business on November 14, 1994, as the record date for
determination of shareholders entitled to notice of and to vote at the Special
Meeting of Shareholders of CIB. The purpose of the Special Meeting of
Shareholders of CIB is (a) to adopt the Articles Amendment, (b) to consider and
vote on a proposal to approve the Merger Agreement and the Merger, and (c) to
transact such other business as may properly come before the meeting.
 
     For additional information with respect to the Special Meeting, see "THE
SPECIAL MEETING."
 
VOTES REQUIRED
 
     The approval of the Articles Amendment requires the approval of more votes
cast in favor thereof than votes cast against the Articles Amendment. The
approval of the Articles Amendment is required in order for the Merger to occur
and is included in the Merger Agreement as a condition to the parties'
obligations to close.
 
     The proposal to approve the Merger Agreement and the Merger to be
considered at the Special Meeting of Shareholders of CIB must be adopted by the
affirmative vote of holders of a majority of the outstanding shares of the CIB
Common. The approval of the Merger Agreement and the Merger by the shareholders
of CIB is required under Section 23-1-40-3 of the Indiana Business Corporation
Law (the "IBCL") and is included in the Merger Agreement as a condition to the
parties' obligations to close. As of November   , 1994, the directors and
executive officers of CIB and their affiliates are entitled to vote
approximately   % of the outstanding shares of CIB Common eligible to vote at
the Special Meeting. CIB has been advised that its directors and executive
officers intend to vote their shares in favor of the Articles Amendment, the
Merger Agreement and the Merger. The Merger Agreement provides that, absent
certain circumstances (none of which has occurred), CIB's Board of Directors
shall recommend that its shareholders vote in favor of and approve the Merger,
the Articles Amendment and the Merger Agreement at its Special Meeting. See "THE
SPECIAL MEETING -- Record Date and Voting Rights."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     The Board of Directors of CIB (a) has unanimously approved the Articles
Amendment and the Merger Agreement, (b) has unanimously recommended the approval
by shareholders of the Articles Amendment and the Merger Agreement, (c) believes
that the proposed Merger is in the best interests of CIB's shareholders, and (d)
unanimously recommends that CIB's shareholders vote FOR the approval of the
Articles Amendment and the Merger Agreement and the Merger. See "MERGER --
Background of and Reasons for the Merger -- CIB."
 
OPINIONS OF FINANCIAL ADVISOR
 
     McDonald & Company Securities, Inc. ("McDonald & Company"), CIB's financial
advisor, has rendered its opinion to CIB's Board of Directors to the effect
that, as of the date of the Merger Agreement was signed and as of the date of
this Prospectus and Proxy Statement, the Exchange Ratio was fair, from a
financial point of view, to the shareholders of CIB. A copy of the fairness
opinion of McDonald & Company is attached hereto as Appendix B and should be
read in its entirety with respect to the assumptions and justification made and
other matters considered. See "MERGER -- Opinions of Financial Advisor."
 
APPRAISAL AND DISSENTERS' RIGHTS
 
     Holders of NCC Common and CIB Common will not be entitled to any statutory
approval and dissenters' rights in connection with the Merger. See "MERGER --
Appraisal and Dissenters' Rights."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES AND ACCOUNTING TREATMENT
 
     The Merger, if completed as proposed, will be treated as a purchase for
accounting and financial reporting purposes. See "MERGER -- Accounting
Treatment."
 
                                        8
<PAGE>   12
 
     The Merger is structured to qualify as a tax-free reorganization under
Section 368(a) of the Code. The Merger Agreement provides as a condition to the
parties' obligations to consummate the Merger that NCC and CIB shall have
received the opinion of Barnes & Thornburg substantially to the effect, among
other things, that for United States federal income tax purposes no gain or loss
will be recognized by the shareholders of CIB who convert their shares of CIB
Common solely for shares of NCC Common pursuant to the Merger (except with
respect to cash received in lieu of a fractional interest in NCC Common). See
"MERGER -- Certain Federal Income Tax Consequences."
 
THE OPTION
 
     As a condition to NCC's entering into the Merger Agreement, and in
consideration therefor, CIB and NCC entered into a Stock Option Agreement dated
as of July 25, 1994 (the "Option Agreement"). The Option Agreement is intended
to increase the likelihood that the Merger will be consummated by making it more
difficult and more expensive for another party to obtain control of or acquire
CIB. See "MERGER -- The Option." A copy of the Option Agreement is attached
hereto as Appendix C.
 
     Pursuant to the Option Agreement, CIB granted NCC an option (the "Option")
to purchase up to 326,000 fully paid and nonassessable shares of CIB Common at a
price of $28.75 per share. In the event that any additional shares of CIB Common
are issued or otherwise become outstanding after the date of the Option
Agreement (other than pursuant to the CIB Option Plans (as hereinafter defined)
as provided for under the Merger Agreement), the number of shares of CIB Common
subject to the Option will be increased so that, after such issuance, it equals
19.9% of the number of shares of CIB Common then issued and outstanding without
giving effect to any shares subject or issued pursuant to the Option. NCC may
exercise the Option only upon the occurrence of certain events (none of which
has occurred) and upon obtaining any regulatory approvals necessary for the
acquisition of shares of CIB subject to the Option. In lieu of exercising the
Option, NCC can require CIB to repurchase for a formula price the Option and any
shares of CIB Common purchased upon exercise of the Option and owned by NCC at
that time. See "MERGER -- The Option." Until the Articles Amendment is adopted
by CIB's shareholders and becomes effective, NCC is prohibited from purchasing
shares which would cause it to own in excess of 10% of CIB's outstanding shares,
and would be prohibited from voting any shares in excess of the 10% limit.
 
     In addition to other Exercise Termination Events (as such term is defined
in "MERGER -- The Option"), the Option Agreement provides that the Option shall
terminate upon the termination of the Merger Agreement in accordance with the
provisions thereof if such termination occurs prior to the occurrence of an
Initial Triggering Event (as such term is defined in "MERGER -- The Option").
The Agreement may be terminated at any time prior to the Effective Time by
either NCC or CIB if the Merger is not approved at the Special Meeting of
Shareholders of CIB (provided that the terminating party is not otherwise in
material breach of its obligations under the Merger Agreement). Accordingly, if
no Initial Triggering Event has occurred, in the event that the CIB shareholders
do not approve the Merger Agreement at the Special Meeting of Shareholders of
CIB, and either NCC or CIB terminates the Merger Agreement as a result thereof,
the Option shall terminate. See "MERGER -- The Option."
 
COMPARATIVE RIGHTS OF HOLDERS OF SHARES OF CIB COMMON AFTER THE MERGER
 
     The rights of holders of shares of CIB Common currently are governed by the
IBCL, CIB's Articles of Incorporation ("CIB's Articles"), and CIB's By-Laws
("CIB's By-Laws"). At the Effective Time, CIB's shareholders will become NCC
stockholders, and their rights will be governed by the Delaware General
Corporation Law (the "DGCL"), NCC's Restated Certificate of Incorporation, as
amended ("NCC's Certificate"), and NCC's First Restatement of By-Laws dated
April 27, 1987 ("NCC's By-Laws"). See "GENERAL COMPARISON OF NCC AND CIB CAPITAL
STOCK."
 
MARKET AND MARKET PRICES
 
     NCC Common is traded on the NYSE. Transactions with respect to CIB Common
are reported on the NASDAQ National Market ("NASDAQ"). Receipt of authorization
for listing on the NYSE of the shares of NCC Common issuable in connection with

n/a -- not applicable
 
(1) CIB has a September 30 fiscal year. In accordance with Regulation S-X, Rule
    3A-02(b)(1), the CIB results of operations for the year ended September 30,
    1993 have been combined with the results of NCC for the year ended December
    31, 1993 for purposes of preparing a pro forma statement of income for the
    year ended December 31, 1993. For the nine months ended September 30, 1994,
    the CIB fiscal 1994 results were adjusted to exclude the first quarter
    activity (ended December 31, 1993) for purposes of preparing a pro
 
                                       11
<PAGE>   15
 
    forma statement of income for the nine months ended September 30, 1994. The
    December 31, 1993 pro forma statement of income also includes the results of
    First Federal Savings and Loan Association of Peru, which was acquired by
    CIB in January 1994.
 
(2) CIB Common was issued in the conversion of CIB's federal savings bank
    subsidiary from mutual to stock form on July 1, 1991. Income and net income
    per share does not include any pro forma earnings on the conversion proceeds
    prior to July 1, 1991.
 
(3) Shareholders' equity includes an amount in each year for which no deferred
    income tax liability has been recognized. These amounts represent an
    allocation of income to bad debt deductions for income tax purposes only.
    Reductions of amounts so allocated for purposes other than tax bad debt
    losses or adjustments arising from carryback of net operating losses would
    create income for tax purposes only, which would be subject to the
    then-current corporate tax rate. At September 30, 1994, such retained
    earnings amounted to $6.3 million and the unrecorded deferred income tax
    liability was $2.1 million. The tax impact of the recapture of this income
    allocated to the bad debt deduction is taken into account in the pro forma
    financial information below.
 
    COMPARATIVE PER SHARE DATA
 
     Based upon the Exchange Ratio of 1.08 shares of NCC Common for each share
of CIB Common outstanding immediately prior to the Merger, the following table
sets forth per common share book value, market value, cash dividends paid,
income before cumulative effect of change in accounting and net income of (a)
NCC on a historical basis, (b) NCC pro forma adjusted to give effect to the
Merger as if the Merger had been effected for the period presented, (c) CIB on a
historical basis, and (d) CIB pro forma equivalent of one share of CIB Common.
The following information should be read in conjunction with the historical
financial statements of NCC and CIB incorporated by reference in this Proxy
Statement and the pro forma condensed combined consolidated financial
information giving effect to the Merger included elsewhere in the Proxy
Statement. See "AVAILABLE INFORMATION"; "INCORPORATION OF CERTAIN DOCUMENTS BY
REFERENCE" and "PRO FORMA CONDENSED COMBINED CONSOLIDATED FINANCIAL INFORMATION
(UNAUDITED)." The data presented below are not necessarily indicative of the
results which actually would have been obtained if the Merger had been
consummated in the past or which may be obtained in the future.

    Standards No. 106 "Employers' Accounting For Postretirement Benefits Other
    Than Pensions" and No. 109 "Accounting For Income Taxes."
 
INTERESTS OF MANAGEMENT IN THE MERGER
 
     NCC will assume the employment agreements of certain members of management
of CIB upon the consummation of the Merger. In addition, NCC has agreed to
certain arrangements relating to retirement and other benefit plans and the
insurance and indemnification of officers and directors of CIB. See "MERGER --
Interests of Management in the Merger."

                              THE SPECIAL MEETING
 
     This Proxy Statement is being furnished to the shareholders of CIB in
connection with the solicitation of proxies by the Board of Directors of CIB for
its Special Meeting of Shareholders and at any adjournment or adjournments
thereof. The Special Meeting of Shareholders of CIB will be held on December 27,
1994, at the Kokomo Country Club, 1801 Country Club Drive, Kokomo, Indiana,
commencing at 4:00 p.m., Eastern Standard Time.
 
RECORD DATE AND VOTING RIGHTS
 
     CIB.  The Board of Directors of CIB has fixed the close of business on
November 14, 1994 as the record date for determination of shareholders entitled
to notice of and to vote at the Special Meeting of Shareholders of CIB. As of
the record date, CIB had outstanding and entitled to vote             shares of
CIB Common. Each share of CIB Common is entitled to one vote. The favorable vote
of the holders of more of the shares of CIB Common than are cast against the
Articles Amendment is required to adopt the Articles Amendment. The affirmative
vote of the holders of a majority of the outstanding shares of CIB Common is
required to approve the Merger Agreement and the Merger under the IBCL.
 
VOTING AND REVOCATION OF PROXIES
 
     Proxies for use at the Special Meeting of the shareholders of CIB accompany
this Prospectus and Proxy Statement. A shareholder may use his or her proxy if
he or she is unable to attend the meeting in person or wishes to have his or her
shares voted by proxy even if he or she does attend the meeting. The proxy may
be revoked in writing by the person giving it at any time before it is exercised
by providing notice of such revocation to the Secretary of CIB, as the case may
be, or by submitting a proxy having a later date, or by such person appearing at
the meeting and electing to vote in person. All proxies validly submitted and
not revoked will be voted in the manner specified therein by the shareholder. If
no specifications are made, shares of CIB Common represented by proxy will be
voted FOR the approval of the Articles Amendment, the Merger Agreement, and the
Merger and for the other matters to be acted upon at the Special Meeting.
Because only the favorable vote of the holders of more of the shares of CIB
Common than are cast against the Articles Amendment is required to adopt the
Articles Amendment, abstentions and broker non votes will have no impact on the
adoption of the Articles Amendment. Because a majority of all of the outstanding
CIB Common must be voted in favor of the Merger Agreement and the Merger,
abstentions and broker non votes will have the effect of a vote against approval
of the Merger.
 
     CIB will bear its own cost of solicitation of proxies from its
shareholders. In addition to using the mails, proxies may be solicited by
personal interview, telephone and wire. It is anticipated that banks, brokerage
houses and other institutions, nominees or fiduciaries will be requested to
forward their proxy soliciting material to their principals and to obtain
authorizations for the executions of proxies. Officers and regular employees of
CIB or its subsidiaries, acting on behalf of CIB, as the case may be, may
solicit proxies personally or by telephone or wire. CIB has retained Morrow &
Co., Inc. to assist in such solicitation. The fee of Morrow & Co., Inc. is
estimated not to exceed $4,000, plus reasonable out-of-pocket costs and
expenses. CIB does not expect to pay any other compensation for the solicitation
of proxies, but may, upon request, pay the standard charges and expenses of
banks, brokerage houses, and other institutions, nominees and fiduciaries for
forwarding proxy materials to and obtaining proxies from their principals.
However, no such payment will be made to any of CIB's subsidiaries acting
through their nominees or acting as fiduciaries.
 
     The Board of Directors of CIB is not aware of any matter other than the
matters set forth in this Prospectus and Proxy Statement that may be presented
for action at the Special Meeting, but if other matters do properly come before
the respective meetings or any adjournments thereof then it is intended that the
shares represented by the accompanying proxy will be voted by the persons named
in the proxy in accordance with their best judgment pursuant to the
discretionary authority granted by the proxy.

                       PROPOSED AMENDMENT TO THE ARTICLES
                            OF INCORPORATION OF CIB
 
     Article 11 of the Articles of Incorporation of CIB provides, in part, that
"no person shall directly or indirectly offer to acquire or acquire beneficial
ownership of more than ten percent (10%) of any class of equity security of the
Corporation." In the event that someone acquires shares in violation of Article
11, such party shall not be entitled to vote any shares in excess of the 10%
limit in connection with any matters submitted to the shareholders of CIB for a
vote. Because NCC is indirectly acquiring all of CIB's outstanding shares in
connection with the Merger, it is necessary to repeal Article 11 in order to
consummate the Merger.
 
     Article 11 would prohibit NCC from exercising the Option for more than 10%
of the outstanding shares of CIB Common. In the absence of a repeal or other
amendment of Article 11, if NCC were to exercise the Option for more than 10% of
the shares of CIB Common, NCC would not be permitted to vote any of such shares
in excess of 10% of the total number of outstanding shares of CIB Common Stock
on any matter submitted to the shareholders of CIB for a vote. See "THE
MERGER -- The Option."
 
     Article 11 provides that the affirmative vote of the holders of at least
80% of the outstanding shares of CIB Common is required to amend or repeal
Article 11 at any time prior to July 1, 1996, unless at least two-thirds of the
current directors of CIB who were directors on March 15, 1991, or directors
recommended for appointment or election by a majority of such directors, have
approved the proposed action prior to the submission of the proposed action to
the shareholders for their vote. All of the directors of CIB have approved the
proposed Articles Amendment, and those directors satisfy the requirements in
Article 11. Accordingly, only the favorable vote of the holders of more of the
shares of CIB Common than are cast against the Articles Amendment is required to
adopt the Articles Amendment.
 
     THE BOARD OF DIRECTORS OF CIB BELIEVES THE ARTICLES AMENDMENT IS IN THE
BEST INTERESTS OF THE SHAREHOLDERS OF CIB AND, THEREFORE, RECOMMENDS THAT THE
SHAREHOLDERS VOTE FOR APPROVAL OF THE ARTICLES AMENDMENT.
 
                                     MERGER
 
     This section of the Prospectus and Proxy Statement describes certain
aspects of the Merger. The following description of the Merger does not purport
to be complete and is qualified in its entirety by reference to the Merger
Agreement and the Option Agreement which are attached as Appendices A and C,
respectively, to this Prospectus and Proxy Statement and are incorporated herein
by reference. Shareholders of CIB are urged to read the Merger Agreement and the
Option Agreement in their entirety.
 
BACKGROUND OF AND REASONS FOR THE MERGER -- CIB
 
     In recent years, there has been, and there continues to be, substantial
consolidation in the United States banking and financial services industry. This
trend is necessarily of concern to smaller institutions, like CIB, because
larger entities that emerge from consolidations may acquire substantial
competitive advantages, including greater diversity in their loan portfolios,
cost savings through the integration of overlapping operations and support
functions, improved access to capital and funding and the ability to spread
costs of new products, services and research and development over a wider
customer base. CIB has been dedicated to the goal of providing superior banking
services primarily in Howard and Miami Counties in Indiana, and in analyzing
strategic alternatives has always sought to ensure that the alternatives being
considered can reasonably be expected to result in improved services as well as
enhanced shareholder value.
 
     In March, 1994, CIB employed McDonald & Company to provide it with an
independent valuation as to the fair market value, on a control basis, of CIB
Common. In May, 1994, CIB engaged McDonald & Company to contact a number of
institutions on behalf of CIB. Institutions contacted included companies which
CIB and McDonald & Company believed would have a strategic interest in CIB and
the financial ability to acquire CIB. After the execution of appropriate
confidentiality agreements and receipt of preliminary indications of interest,
subject to due diligence, four companies were offered the opportunity to conduct
a business review of CIB in order to formulate a firm offer which would not be
conditioned upon the performance of a further business review by the offeror.
All four of the companies availed themselves of this opportunity. In June, 1994,
each of the four conducted in-depth examinations of the books, records and
operations of CIB.
 
                                       15
<PAGE>   19
 
     Upon conclusion of their examinations, each of the companies that had
conducted a business review submitted an offer. CIB, with the assistance of
McDonald & Company, analyzed each offer and determined that the proposal
submitted by NCC offered the greatest value to CIB shareholders and could
reasonably be expected to result in the continuation and enhancement of the
quality banking services which CIB traditionally provided in Howard and Miami
Counties, Indiana. In addition, the Exchange Ratio proposed by NCC would produce
a dividend rate for CIB shareholders who became NCC stockholders that would be
substantially higher than the dividend rate on CIB Common at the time and the
dividend rate under the proposals made by the other three financial
institutions.
 
     After consulting with McDonald & Company and with legal counsel, CIB
determined that it would negotiate a definitive agreement with NCC. While such
negotiations were taking place, one of the other offerors revised its bid
upward, but NCC's offer, in the opinion of CIB and McDonald & Company, continued
to be superior. On July 25, 1994, NCC and CIB completed negotiations of the
Merger Agreement and of the Option Agreement, which NCC required as a condition
to entering into the Merger Agreement.
 
     In reaching the determination that the Merger is fair to, and in the best
interests of, CIB and its shareholders, the CIB Board of Directors consulted
with CIB management, as well as its financial and legal advisors, and considered
a number of factors, including, without limitation, the following:
 
          (a) CIB's business, operations, earnings, prospects and financial
     condition;
 
          (b) the business, operations, earnings, prospects and financial
     condition of NCC as determined from the business review conducted by CIB
     management, the enhanced opportunities for operating efficiencies
     (particularly in terms of integration of operations and support functions)
     that could result from the Merger, and the enhanced opportunities for
     growth that the Merger would make possible;
 
          (c) the opinion of McDonald & Company that as of July 25, 1994, the
     Exchange Ratio was fair to CIB shareholders from a financial point of view;
 
          (d) the bidding process conducted by CIB with the assistance of
     McDonald & Company and CIB's counsel, and the bids made by other financial
     institutions;
 
          (e) the value implicit in the Exchange Ratio in relation to the then
     current market value, book value and earnings of CIB, and the increased
     dividend rate that CIB shareholders who become NCC stockholders are
     expected to enjoy as a result of the Merger, and the fact that CIB would be
     unlikely to match or exceed such value in the foreseeable future by
     remaining independent;
 
          (f) comparisons to median transaction multiples of other pending
     thrift acquisitions in terms of premium to book value and earnings;
 
          (g) the terms of the Merger Agreement and the Option Agreement;
 
          (h) NCC's record as an institution that is consistently ranked near
     the top of its peer group of regional bank holding companies in terms of
     asset quality, reserve coverage, capital adequacy and profitability;
 
          (i) the market prices at which NCC Common has been trading in recent
     periods;
 
          (j) alternatives to the Merger (including the alternatives of
     remaining independent and growing internally and remaining independent for
     a period of time and then selling CIB) and the competitive problems that
     CIB was likely to encounter as an independent company;
 
          (k) the apparent absence of any significant problems in obtaining
     regulatory approvals for the Merger and the fact that the pro forma capital
     position of the combined companies would be well in excess of all
     applicable regulatory capital requirements;
 
          (l) the expectation that the Merger will be a tax-free transaction to
     CIB and will generally be a tax-free transaction to its shareholders who
     receive solely NCC Common (except cash in lieu of fractional shares) (see
     "MERGER -- Certain Federal Income Tax Consequences"); and
 
                                       16
<PAGE>   20
 
          (m) the current and prospective economic environment and competitive
     constraints facing financial institutions, including CIB.
 
     The CIB Board of Directors did not assign any specific or relative weight
to the foregoing factors in its consideration.
 
     IN VIEW OF ALL THE CONSIDERATIONS DESCRIBED ABOVE, THE BOARD OF DIRECTORS
OF CIB UNANIMOUSLY RECOMMENDS THAT CIB SHAREHOLDERS VOTE FOR THE APPROVAL OF THE
MERGER AGREEMENT AND RELATED MERGER.
 
BACKGROUND OF AND REASONS FOR THE MERGER -- NCC
 
     Since establishing a major presence in Indiana by acquiring Merchants
National Corporation, now known as National City Bank, Indiana, in 1992, NCC has
sought to enhance its Indiana network through internal growth and select
acquisitions. NCC was contacted by McDonald & Company in May 1994 and was
informed that CIB was considering affiliating with another financial
institution. CIB was an attractive candidate, offering an opportunity to fill in
a gap in NCC's central Indiana franchise. In May 1994, upon executing a
confidentiality agreement and receiving confidential information, NCC submitted
a non-binding indication of interest for CIB. NCC was then chosen to participate
in a business review of CIB in June 1994. Due diligence teams from NCC focused
on asset and credit quality, risk management, consolidation and centralization
opportunities, cost savings and revenue enhancement opportunities and management
issues. The due diligence review verified the confidential information which had
been provided by CIB and used by NCC as the basis for its May 1994 non-binding
indication of interest and discovered nothing that warranted NCC abandoning the
transaction. NCC also used the due diligence process to identify potential cost
savings of approximately $2 million (or 38% of CIB's non-interest expense base)
once CIB is totally integrated with National City Bank, Indiana, which
integration is anticipated to be completed in the second quarter of 1995. NCC
submitted a revised bid on July 8, 1994, subject to a definitive agreement. On
July 25, 1994, the parties executed and delivered the Merger Agreement and the
Option Agreement.
 
     In negotiating the terms of the Merger, NCC's management reviewed a number
of factors with a view to maximizing stockholder value in the intermediate and
long term future, including earnings potential, realization of economies of
scale, and geographic diversification. In addition, NCC's Board of Directors
consulted with NCC management, as well as its legal advisors, and considered
other factors, including, without limitation, the following: (a) the business,
operations, earnings prospects and financial condition of CIB as determined from
the business review conducted by NCC management; (b) the terms of the Merger
Agreement and the Option Agreement; and (c) regulatory approval requirements.
 
     NCC believes that the affiliation of CIB with NCC and the acquisition of
its savings bank subsidiary now owned by CIB will enhance NCC's presence in
central Indiana and expand its customer base and assets.
 
     NCC has had substantial prior experience in effecting successful mergers
including four major bank holding company mergers (BancOhio Corporation in 1984,
First Kentucky National Corporation in 1988, Merchants National Corporation in
1992 and Ohio Bancorp in 1993), as well as thrift and other non-bank
acquisitions. At this time, NCC has completed virtually all of its own
standardization and consolidation projects and believes it can effectively
integrate and consolidate the operations of CIB into NCC within six months after
the consummation of the Merger, thereby realizing the full benefits of the
Merger within a relatively short time period. NCC's Board of Directors believes
that the Merger will result in a combined entity with increased financial
resources and greater financial strength than either NCC or CIB standing alone.
The realization of anticipated cost savings, coupled with revenue enhancements
at CIB, should make the Merger accretive to NCC's earnings per share in 1995,
assuming no unexpected delays in consummating the Merger. There can be no
assurance that such integration or consolidation of the operations of CIB and
NCC will occur in such period or at any time in the future.
 
     It is anticipated that, simultaneously with the merger of CIB into NCC,
CIB's savings bank subsidiary, First Federal Savings Bank of Kokomo ("Kokomo"),
may merge with and into National City Bank, Indiana ("NCB"), one of NCC's bank
subsidiaries based in Indianapolis, Indiana. But as indicated above, the
integration of Kokomo's operations with those of NCB may not be completed until
a later time.

OPINIONS OF CIB'S FINANCIAL ADVISOR
 
     CIB has retained McDonald & Company as its financial advisor in connection
with the Merger and requested that McDonald & Company render its opinion with
respect to the fairness, from a financial point of view, of the Exchange Ratio
to the holders of CIB Common. McDonald & Company rendered its oral opinion to
the CIB Board of Directors on July 25, 1994, which it subsequently confirmed in
writing, that as of the date of such opinion, the Exchange Ratio pursuant to the
Merger was fair, from a financial point of view, to the holders of CIB Common.
McDonald & Company updated its July 25, 1994 opinion as of the date of this
Prospectus and Proxy Statement. The updated opinion is attached as Appendix B to
this Prospectus and Proxy Statement. The Merger Agreement contains as a
condition to closing the requirement that McDonald & Company also update its
opinion as of the date of the Special Meeting.
 
     In arriving at its July 25, 1994 opinion, McDonald & Company reviewed,
among other things, the Merger Agreement together with exhibits and schedules
thereto, certain publicly available information relating to the business,
financial condition and operations of CIB and NCC as well as certain other
non-public information, primarily financial in nature, furnished to it by CIB
and NCC relating to the respective businesses, earnings, assets, financial
forecasts and prospects. McDonald & Company also held discussions with members
of senior management of CIB and NCC concerning their respective businesses,
assets, financial forecasts and prospects. McDonald & Company also reviewed
certain publicly available information concerning the trading of, and the
trading market for, CIB Common and NCC Common and certain publicly available
information concerning comparable companies and transactions, all as more fully
set forth in McDonald & Company's opinion.
 
     McDonald & Company was not engaged to and did not conduct a physical
inspection of any of the assets, properties or facilities of either CIB or NCC,
and was not engaged to and has not made, obtained or been furnished with any
independent evaluation or appraisal of any such assets, properties or facilities
or any of the liabilities of CIB or NCC. McDonald & Company has assumed and
relied, without independent investigation, upon the accuracy and completeness of
the financial and other information provided to it or publicly available, has
relied upon the representations and warranties of CIB and NCC contained in the
Merger Agreement, and has not independently attempted to verify any of such
information. McDonald & Company has also assumed that all of the conditions to
the Merger as set forth in the Merger Agreement, including the tax-free
treatment of the Merger to the shareholders of CIB Common, would be satisfied
and that the Merger would be consummated on a timely basis in the manner
contemplated by the Merger Agreement. No limitations were imposed by CIB upon
McDonald & Company with respect to the scope of its investigation nor were any
specific instructions given to McDonald & Company in connection with its
opinion.
 
     In connection with rendering its opinion dated July 25, 1994, McDonald &
Company considered a variety of financial analyses which are summarized below.
McDonald & Company believes that its analyses must be considered as a whole and
that selecting portions of such analyses and factors may create an incomplete
view of the analytical process underlying McDonald & Company's opinion. In its
analyses, McDonald & Company made numerous assumptions with respect to industry
performance, business and economic conditions, and other matters. Any estimates
contained in McDonald & Company's analyses are not necessarily indicative of
future results or values, which may be significantly more or less favorable than
such estimates.
 
     The following is a summary of selected analyses considered by McDonald &
Company in connection with McDonald & Company's opinion dated July 25, 1994:
 
     COMPARISON WITH SELECTED COMPANIES.  McDonald & Company compared the
financial performance and stock market valuation of CIB with corresponding data
for the following selected thrifts: Ameriana Bancorp, FirstFed Bancshares, FFW
Corp., Financial Security Corp., Kankakee Bancorp, Inc., Liberty Bancorp, Marion
Capital Holdings, Inc., Peoples Bancorp, Westco Bancorp, and Workingmens Capital
Holdings, Inc. In addition, McDonald & Company compared such data of NCC with
the following selected banking companies: Barnett Banks, Inc., Boatmen's
Bancshares, Inc., CoreStates Financial Corp., First Bank Systems, Inc., Fleet
Financial Group, First Union Corp., KeyCorp, Mellon Bank Corp., NBD Bancorp,
Inc., Norwest Corp., Banc One Corp., PNC Bank Corp., SunTrust Banks, Inc., U.S.
Bancorp, and Wachovia Corp. At the time, none of the companies listed above had
announced a merger transaction or disclosed a possible interest in pursuing a
possible merger transaction which would have significantly affected its stock
market valuation.
 
                                       18

     PRO FORMA MERGER ANALYSIS.  McDonald & Company analyzed the changes in the
per share amount of earnings, book value and indicated dividend represented by
one share of CIB Common after the Merger. The analysis was performed on the
basis of financial information for both companies as of and for the three months
ended March 31, 1994 and the twelve month periods ended December 31, 1993 and
1992. The analysis indicated, among other things, that exchanging one share of
CIB Common at the Exchange Ratio for shares of NCC Common on a pro forma basis
would have resulted in a 54.5% increase in earnings per share for each share of
CIB Common for the three months ended March 31, 1994, a 13.3% decrease in book
value per share for each share of CIB Common as of March 31, 1994, and a 164%
increase in dividends per share for each share of CIB Common based on CIB's and
NCC's indicated annual dividend rate as of July 25, 1994.
 
     ANALYSIS OF SELECTED MERGER TRANSACTIONS.  McDonald & Company reviewed five
groups of selected pending thrift acquisition transactions involving (i) mergers
with transaction values between $40 million and $60 million, (ii) selling
thrifts having equity to assets ratios greater than 10%, (iii) selling thrifts
having a return on average assets greater than 1.00%, (iv) selling thrifts
having non-performing assets as a percent of total assets less than 0.75%, and
(v) selling thrifts headquartered in the Midwest region of Iowa, Illinois,
Indiana, Kansas, Kentucky, Michigan, Minnesota, Missouri, North Dakota,
Nebraska, Ohio, South Dakota, and Wisconsin. McDonald & Company reviewed the
ratios of the offer value to stated book value and tangible book value, the
multiple of the last 12 months earnings of the acquired company, and the ratio
of the offer value to assets in each such transaction and computed the mean and
median ratios and multiples for each group. The calculations yielded ranges of
median ratios of price to stated book value and tangible book value of 152% to
166%, and 152% to 171%, respectively. Median multiples of earnings among the
five groups ranged from 12.4x to 14.8x; and median ratios of offer value to
assets ranged from 14% to 19%. Based on the Exchange Ratio and the CIB
equivalent per share price as of July 22, 1994 of $28.485, the ratio of price to
stated book value and tangible book value were each 133%, the multiple of price
to the last 12 months earnings of CIB through March 31, 1994 was 17.0x and the
ratio of price to assets at March 31, 1994 was 19%.
 
     NO COMPANY OR TRANSACTION USED IN THE ABOVE ANALYSES AS A COMPARISON IS
IDENTICAL TO CIB, NCC, OR THE MERGER. ACCORDINGLY, AN ANALYSIS OF THE RESULTS OF
THE FOREGOING NECESSARILY INVOLVES COMPLEX CONSIDERATIONS AND JUDGMENTS
CONCERNING THE DIFFERENCES IN FINANCIAL AND OPERATING CHARACTERISTICS OF THE
COMPANIES AND OTHER FACTORS THAT COULD AFFECT THE PUBLIC TRADING VALUES OR
ACQUISITION VALUES OF THE COMPANIES TO WHICH THEY ARE BEING COMPARED.
MATHEMATICAL ANALYSIS (SUCH AS DETERMINING THE MEAN OR MEDIAN) IS NOT, IN
ITSELF, A MEANINGFUL METHOD OF USING COMPARABLE COMPANY OR COMPARABLE
TRANSACTION DATA.
 
     DISCOUNTED CASH FLOW ANALYSIS.  Using discounted cash flow analysis,
McDonald & Company estimated the present value of the future streams of
after-tax cash flows that CIB could produce over a five year period from 1995
through 1999, under various assumptions, based upon CIB's management forecasts.
McDonald & Company estimated the terminal value of CIB after the five year
period by two methods: (i) projecting a perpetual growth rate of the terminal
year's after-tax cash flows, and (ii) applying multiples ranging from 10x to 14x
the terminal year's earnings. The cash flow streams and terminal values were
then discounted to present values using different discount rates chosen to
reflect different assumptions regarding the required rates of return of
prospective buyers of CIB. On the basis of such varying assumptions, this
discounted cash flow analysis indicated a reference range of $20.14 to $30.19
per share of CIB Common. This analysis was based upon management projections
including variations and assumptions made by McDonald & Company which included
adjustments to reflect the anticipated effects of potential merger-related cost
savings estimated by CIB, as well as the effects of the potential tax liability
for conversion of Kokomo to a commercial bank charter. Management's projections
are based upon many factors and assumptions, many of which are beyond the
control of CIB or NCC. As indicated above, this analysis is not necessarily
indicative of actual values or actual future results and does not purport to
reflect the prices at which any securities may trade at the present time or at
any time in the future.
 
     In performing its analyses, McDonald & Company made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters. The analyses performed by McDonald & Company are not
necessarily indicative of actual values, which may be significantly more or less
favorable than the values suggested by such analyses. Such analyses were
prepared solely as part of McDonald & Company's opinion. The term "fair from a
financial point of view" is a standard phrase contained in investment
 
                                       19
<PAGE>   23
 
banker fairness opinions and refers to the fact that McDonald & Company's
opinion as to the fairness of the Exchange Ratio is addressed solely to the
financial attributes of the Exchange Ratio. The analyses do not purport to be
appraisals or to reflect the prices at which a company might actually be sold.
In addition, as described above, McDonald & Company's opinion and presentation
to the CIB Board of Directors were one of many factors taken into consideration
by the CIB Board of Directors in making its determination to approve the Merger
Agreement. Consequently, the McDonald & Company analyses described above should
not be viewed as determinative of the CIB Board of Directors' conclusions with
respect to the value of CIB or of the decision of the CIB Board of Directors to
agree to the Exchange Ratio.
 
     McDonald & Company's opinions are based on economic and market conditions
and other circumstances existing on, and information made available as of, the
date of such opinion. In addition, the opinions do not address CIB's underlying
business decision to effect the Merger or any other terms of the Merger.
McDonald & Company is not rendering any opinion as to the value of CIB Common or
NCC Common at the Effective Time.
 
     In connection with its opinion dated as of the date of this Prospectus and
Proxy Statement, McDonald & Company performed procedures to update certain of
its analyses and reviewed the assumptions on which such analyses were based and
the factors considered therewith.
 
     McDonald & Company, as part of its investment banking business, is
customarily engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. McDonald & Company has
extensive experience with the valuation of financial institutions. CIB's Board
of Directors selected McDonald & Company as its financial advisor because of
McDonald & Company's industry expertise with respect to financial institutions
and because of its substantial experience in transactions similar to the Merger.
McDonald & Company is not affiliated with either CIB or NCC.
 
     In the ordinary course of business, McDonald & Company makes a market in
CIB's Common and may actively trade the securities of CIB and NCC for its own
account and for the accounts of its customers. Accordingly, at any time McDonald
& Company may hold a long or short position in such securities. In addition,
McDonald & Company from time to time has provided investment banking services to
CIB and NCC and may provide such services to NCC in the future.
 
     For its services as financial advisor, CIB has paid McDonald & Company a
retainer of $50,000 and a fee of $75,000 upon the rendering of the oral fairness
opinion. Additional fees equal to $275,000 will be payable to McDonald &
Company, with $45,000 due upon shareholder approval and $230,000 due upon
consummation of the Merger. CIB has also agreed to reimburse McDonald & Company
for its reasonable out-of-pocket expenses and to indemnify McDonald & Company,
its officers, directors and controlling persons against certain liabilities,
including certain liabilities under federal securities law.
 
     THE FULL TEXT OF THE OPINION OF MCDONALD & COMPANY UPDATED AS OF THE DATE
OF THIS PROSPECTUS AND PROXY STATEMENT, WHICH SETS FORTH CERTAIN ASSUMPTIONS
MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEWS UNDERTAKEN, IS ATTACHED
AS APPENDIX B TO THIS PROSPECTUS AND PROXY STATEMENT, AND SHOULD BE READ IN ITS
ENTIRETY. THE SUMMARY OF THE OPINION OF MCDONALD & COMPANY SET FORTH IN THIS
PROSPECTUS AND PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
OPINION. MCDONALD & COMPANY'S OPINION SHOULD NOT BE CONSTRUED BY HOLDERS OF CIB
COMMON STOCK AS A RECOMMENDATION AS TO HOW SUCH HOLDERS SHOULD VOTE AT THE
SPECIAL MEETING.
 
TERMS OF THE MERGER
 
     The Merger Agreement provides for the merger of CIB with and into NCC. Upon
consummation of the Merger, (a) the separate corporate existence of CIB will
cease, (b) NCC will be the surviving corporation and will continue to be
governed by the laws of Delaware, (c) the name of the surviving corporation will
continue to be National City Corporation, (d) the Certificate of Incorporation
and By-Laws of NCC in effect immediately prior to the Effective Time will become
the Certificate of Incorporation and By-Laws of NCC, (e) the directors and
officers of NCC will continue as the directors and officers of NCC, and (f) the
title to all real estate and other
 
                                       20
<PAGE>   24
 
property owned by CIB will be vested in NCC, and all proceedings, rights of
creditors against and any liens upon the property of CIB will become the
obligations of NCC.
 
CONVERSION OF SHARES OF CIB COMMON
 
     Conversion of Shares of CIB Common. At the Effective Time, (a) each then
outstanding share of CIB Common not owned by NCC or any direct or indirect
wholly owned subsidiary of NCC (except for any such shares of CIB Common 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 debt
previously contracted ("DPC Shares") shall not be deemed owned by NCC), other
than those shares of CIB Common held in the treasury of CIB, will be cancelled,
retired and converted into the right to receive 1.08 shares of NCC Common; (b)
each then outstanding share of CIB Common 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 cancelled and retired; and (c) each share of CIB
Common issued and held in CIB's treasury will be cancelled and retired. If
between July 25, 1994 and the Effective Time, the shares of NCC Common are
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 such period, the
Exchange Ratio will be adjusted accordingly.
 
     No Fractional Shares. No certificates or scrip representing fractional
shares of NCC Common will be issued in the Merger. No dividends or distributions
of NCC will be payable on or with respect to any fractional share and any such
fractional share interest will not entitle the owner thereof to vote as to any
rights of stockholders of NCC. In lieu thereof, each holder of CIB Common who
otherwise would have been entitled to a fractional share of NCC Common will
receive cash in an amount determined by multiplying the fractional share
interest to which such holder would otherwise be entitled by the average of the
per share closing price on the NYSE of NCC Common for the 20 consecutive trading
days ending at the end of the fifth trading day immediately preceding the
Closing Date.
 
     Manner of Exchanging CIB Certificates for NCC Certificates. NCC has
designated NCB to act as exchange agent (the "Exchange Agent") and Kokomo to act
as forwarding agent in connection with the Merger. Promptly after the Effective
Time, the Exchange Agent will mail to each holder of record of a certificate (a
"Certificate") which immediately prior to the Effective Time represented
outstanding shares of CIB Common a notice advising the holder of the
effectiveness of the Merger accompanied by a letter of transmittal. The letter
of transmittal will contain instructions with respect to the procedures to be
followed in effecting the surrender of the Certificate for exchange therefor and
will specify that delivery will be effected, and risk of loss and title to such
Certificate will pass, only upon proper delivery of the Certificate to the
Exchange Agent. 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 promptly will deliver to the person entitled
thereto a certificate(s) representing 1.08 shares of NCC Common for each share
of CIB Common so represented by the Certificate surrendered by such holder
thereof (and cash in lieu of a fractional share of NCC Common), and such
Certificate will then be cancelled. If delivery of all or part of the shares of
NCC Common is to be made to a person other than the person in whose name a
surrendered Certificate is registered, it will be a condition to such delivery
or exchange that the Certificate so surrendered shall be properly endorsed or
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 so surrendered or shall have established to the
reasonable satisfaction of the Exchange Agent that such tax either has been paid
or is not payable.
 
     CERTIFICATES FOR SHARES OF CIB COMMON SHOULD NOT BE FORWARDED TO THE
EXCHANGE AGENT UNTIL A CIB SHAREHOLDER HAS RECEIVED A TRANSMITTAL LETTER AND
SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY.
 
     Right to Shares of NCC Common. Until surrendered and exchanged in
accordance with the procedures set forth in the letter of transmittal, after the
Effective Time, each Certificate shall represent solely the right to receive
1.08 shares of NCC Common, multiplied by the number of shares of CIB Common
evidenced by such Certificate, together with any dividends or other
distributions as provided in "Distribution with Respect to
 
                                       21
<PAGE>   25
 
Unexchanged Certificates" below, and shall have no other rights except as
described in "Voting With Respect to Unexchanged Certificates" below. One
hundred eighty (180) days following the Effective Time, the Exchange Agent will
deliver to NCC any shares of NCC Common and funds (including any interest
received with respect thereto) which NCC has made available to the Exchange
Agent and which have not been disbursed to holders of Certificates, and
thereafter such holders shall be entitled to look to NCC (subject to abandoned
property, escheat or other similar laws) with respect to the shares of NCC
Common and cash in lieu of fractional shares deliverable or payable upon due
surrender of their Certificates. Neither the Exchange Agent, NCC, nor CIB shall
be liable to any holder of shares of CIB Common for any shares of NCC Common (or
dividends, distributions or interest with respect thereto) or cash in lieu of
fractional shares delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.
 
     Distribution with Respect to Unexchanged Certificates. Whenever a dividend
or other distribution is declared by NCC on the NCC Common, the record date for
which is at or after the Effective Time, the declaration will include dividends
or other distributions on all shares issuable in the Merger, provided that no
dividends or other distributions declared or made with respect to NCC Common
with a record date that is more than 30 days after the mailing of the notice and
letter of transmittal described in "Manner of Exchanging CIB Certificates for
NCC Certificates" will be paid to the holder of any unsurrendered Certificate
with respect to the shares of NCC Common represented thereby until the holder of
such Certificate has surrendered such Certificate in accordance with the
instructions set forth in the letter of transmittal. NCC will pay any dividends
and make any other distributions with a record date prior to the Effective Time
which may have been declared or made by CIB on CIB Common in accordance with the
terms of the Merger Agreement on or prior to the Effective Time and which remain
unpaid at the Effective Time.
 
     Voting With Respect to Unexchanged Certificates. Holders of unsurrendered
Certificates will not be entitled to vote after a date that is more than 30 days
after the mailing of the notice and letter of transmittal described in "Manner
of Exchanging CIB Certificates for NCC Certificates" at any meeting of NCC
stockholders with respect to the number of shares of NCC Common represented by
such Certificates, or exercise his other rights as a stockholder of NCC with
respect thereto, unless and until he has surrendered those Certificates in
accordance with the terms of the Merger Agreement.
 
     Lost Certificates. Any CIB shareholder who has lost or misplaced a
Certificate for any of his or her shares of CIB Common should immediately call
Bank One, Indianapolis, NA (telephone number: (317) 321-8110) for information
regarding the procedures to be followed for replacing the lost certificate.
Until such lost or replaced Certificate is found or a replacement Certificate is
obtained, the CIB shareholder will be unable to properly submit the transmittal
letter.
 
ASSUMPTION OF EMPLOYEE AND DIRECTOR STOCK OPTIONS
 
     The Merger Agreement provides that all rights under any stock option
granted by CIB pursuant to CIB's Stock Option Plan and CIB's 1993 Stock Option
Plan (collectively, the "CIB Option Plans") that remain unexercised immediately
prior to the Effective Time ("Unexercised Options") will be assumed by NCC, but
will thereafter represent the right to acquire that number of shares of NCC
Common to which the optionee would have been entitled pursuant to the Exchange
Ratio if immediately prior to the Merger the optionee had fully exercised the
option and had been a shareholder of record of CIB. The option price of each
option will 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 the Merger Agreement, 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 will file, and maintain
the effectiveness of, a registration statement with the Commission covering the
Unexercised Options and the sale of the NCC Common issued upon the exercise of
the Unexercised Options. At the Effective Time, all of the CIB Option Plans will
be terminated with respect to the granting of any additional options or option
rights. See pages 27 through 28 for the description of the impact of the Merger
on CIB's other employee benefit plans.

     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 the Merger Agreement so as to

     either NCC or CIB, the consummation of the Merger;
 
          (d) The Registration Statement shall have become effective in
     accordance with the provisions of the 1933 Act, and no stop order

     Merger will be treated for federal income tax purposes as a reorganization
     within the meaning of Section 368(a) of the Code. See "MERGER -- Certain
     Federal Income Tax Consequences."
 
     Conditions to CIB's Obligations. The obligation of CIB to effect the Merger

     Agreement shall be true in all material respects as of the Effective Time
     as if made at and as of the Effective Time, except as expressly

     in all material respects at such time or times; and
 
          (c) NCC shall have received all officers' certificates of CIB required

REGULATORY APPROVALS
 
     The Merger is subject to approval by the FRB under the BHCA. The BHCA
prohibits the FRB from approving the Merger if (a) it would result in a
monopoly; (b) it would be in furtherance of any combination or conspiracy to
monopolize the business of banking in any part of the United States; (c) its
effect in any section of the country may be substantially to lessen competition
or to tend to create a monopoly; or (d) it would be in any other manner in
restraint of trade, unless the FRB finds that any anticompetitive effects of the
Merger are clearly outweighed in the public interest by the probable effect of
the transaction in meeting the convenience and needs of the communities to be
served. The Merger may not be consummated until the 30th day after approval by
the FRB, during which time the Merger may be challenged on antitrust grounds by
the Department of Justice.
 
     In addition, the BHCA requires that the FRB take into consideration, among
other facts, the financial and managerial resources and future prospects of the
institutions and the convenience and needs of the communities to be served. The
FRB has the authority to deny an application if it concludes that the combined
organization would have an inadequate capital position or if the acquiring
organization does not meet the requirements of the Community Reinvestment Act of
1977.
 
     NCC (with the assistance of CIB) filed an application for the FRB approval
of the Merger, and the Merger was approved by the FRB on October 20, 1994.
 
     NCC and CIB are not aware of any other governmental approvals or actions
that are required for consummation of the Merger, except as described above.
Should any such approval or action be required, it is presently contemplated
that such approval or action would be sought. There can be no assurance that any
such approval or action, if needed, could be obtained and would not be
conditioned in a manner that would cause NCC to abandon the Merger.
 
WAIVER; AMENDMENT; TERMINATION
 
     Waiver. Any party to the Merger Agreement may, by written notice to the
other parties thereto, (a) extend the time for the performance of any of the
obligations or other actions of the other party under the Merger Agreement; (b)
waive any inaccuracies in the representations or warranties of the other parties
contained in the Merger Agreement or in any document delivered pursuant to the
Merger Agreement; (c) waive compliance with any of the conditions or covenants
of the other party contained in the Merger Agreement; or (d) waive or modify
performance of any of the obligations of the other party under the Merger
Agreement. Notwithstanding these provisions, the Merger cannot be consummated
unless the shareholders of CIB approve the Articles Amendment, the Merger
Agreement, and the Merger by the requisite affirmative votes. See "MERGER --
Regulatory Approvals" and "THE ANNUAL MEETING -- Record Date and Voting Rights."
 
     Amendment. Subject to the applicable provisions of the DGCL and the IBCL,
the Merger Agreement may be amended or supplemented upon the written agreement
of NCC and CIB at any time, provided that an amendment may not be made after any
shareholder approval of the Merger Agreement which reduces or changes the form
of the Merger consideration without further shareholder approval.
 
     Termination. The Merger Agreement may be terminated at any time prior to
the Effective Time, whether before or after the approval by shareholders of CIB
of the Merger Agreement, under the following circumstances:
 
          (a) by the mutual consent of the Board of Directors of NCC and the
     Board of Directors of CIB;
 
          (b) by the Board of Directors of either NCC or CIB if the Merger shall
     not have been consummated on or before June 30, 1995 or if the Merger
     Agreement is not approved by the CIB shareholders at CIB's Special Meeting
     (provided the terminating party is not otherwise in material breach of its
     obligations under the Merger Agreement);
 
                                       24
<PAGE>   28
 
          (c) by the Board of Directors of CIB if any of the conditions to CIB's
     obligation to consummate the Merger have not been met or waived by CIB at
     such time as such conditions can no longer be satisfied. See "MERGER --
     Conditions to the Merger -- Conditions to Each Party's Obligations" and
     "Conditions to CIB's Obligations";
 
          (d) by the Board of Directors of NCC if any of the conditions to NCC's
     obligation to consummate the Merger have not been met or waived by NCC at
     such time as such conditions can no longer be satisfied. See "MERGER --
     Conditions to the Merger -- Conditions to Each Party's Obligations" and
     "Conditions to NCC's Obligations"; and
 
          (e) by CIB if both of the following conditions are met:
 
             (i) the Market Price of NCC Common is less than $24.50; and
 
             (ii) the number obtained by dividing the Market Price of NCC Common
        by $26.375 (the closing price of NCC Common on the NYSE on July 22,
        1994, the trading day immediately preceding the public announcement of
        the Agreement) is less than the number obtained by dividing the Final
        Index Price (as defined below) by the Initial Index Price (as defined
        below) and subtracting 0.10 from the quotient. For purposes of the
        Agreement:
 
                (A) the term "KBW 49" means the 50 bank holding companies listed
           in the Keefe Bruyette & Woods, Inc. KBW 50 Total Return Index
           excluding NCC. In the event that the companies comprising the KBW 49
           are changed, the weights attributed to the resulting companies shall
           be adjusted proportionately for purposes of determining both the
           Initial Index Price and Final Index Price.
 
                (B) the term "Initial Index Price" means the
           market-capitalization-weighted average of the closing prices on July
           22, 1994 of the common stock of the companies comprising the KBW 49;
 
                (C) the term "Final Price" of any company belonging to the KBW
           49 means the average of the daily closing sale prices of a share of
           the common stock of such company, reported in the consolidated
           transaction reporting system for the market or exchange on which such
           common stock is principally traded, during the period of 20
           consecutive trading days ending at the end of the fifth trading day
           immediately preceding the Closing Date; and
 
                (D) the term "Final Index Price" means the
           market-capitalized-weighted average of the Final Prices for all of
           the companies comprising the KBW 49.
 
     The Agreement provides that if NCC or any company belonging to the Index
     Group declares a stock dividend or effects a reclassification,
     recapitalization, split-up, combination, exchange of shares or similar
     transaction between July 25, 1994 and the fifth trading date prior to the
     Closing Date, the closing prices for the common stock of such company will
     be appropriately adjusted for purposes of the foregoing definitions so as
     to be comparable to the price on July 25, 1994.
 
     Expenses. (a) If the Merger is consummated, it is estimated that the costs
and expenses incurred in connection with the Merger Agreement and the
transactions contemplated thereby will be $1.0 million in the aggregate.
 
     (b) In the event the Merger Agreement is terminated by NCC or CIB because
of the willful breach by the other party of any representation, warranty,
covenant, undertaking or restriction contained in the Agreement, and if the
terminating party is not in material breach of any representation, warranty,
covenant, undertaking or restriction contained in the Merger Agreement, then the
breaching party shall pay all costs and expenses of the terminating party;
provided, however, that if the Merger Agreement is terminated under
circumstances other than the ones described above in this paragraph, all costs
and expenses incurred in connection with the Merger Agreement, and the
transactions contemplated thereby will be paid by the party incurring such costs
and expenses. If termination is due to a willful breach, the payment of expenses
pursuant to the Merger Agreement shall not constitute the non-breaching party's
sole legal remedy. Final settlement with respect to payment of fees and expenses
by the parties shall be made within 30 days of the termination of the Merger
Agreement.
 
                                       25
<PAGE>   29
 
     Assignment. Without the prior written consent of the other parties to the
Agreement, neither NCC nor CIB may assign any of its rights or delegate any of
its obligations under the Agreement.
 
EFFECTIVE TIME
 
     As soon as practicable after satisfaction or waiver of all conditions to
the Merger under the Merger Agreement, NCC and CIB 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 complying with the requirements of the IBCL (the "Articles of Merger") to
be filed with the Secretary of State of the State of Indiana, respectively. The
Merger will become effective at the later of (a) the times at which such filings
are made with the Secretaries of State of the States of Delaware and Indiana
(the "Effective Time") or (b) such later dates as are specified in such filings.
NCC and CIB currently anticipate that the Merger will be completed late in the
fourth calendar quarter of 1994 or early in the first calendar quarter of 1995.
Delays in the completion of the Merger could occur, however, as a result of
delays in obtaining the necessary regulatory approvals. See "MERGER --
Regulatory Approvals." In the event the Merger is not consummated on or before
June 30, 1995, either NCC or CIB may terminate the Merger Agreement. See "MERGER
- - - -- Waiver; Amendments; Termination -- Termination."
 
CONDUCT OF CIB'S BUSINESS PENDING THE MERGER
 
     General. The Merger Agreement requires that from July 25, 1994 to the
Effective Time, CIB and its subsidiaries conduct their respective business only
in, and not take any action except in, the ordinary course of business
consistent with past practice. CIB has covenanted to use reasonable efforts to
preserve intact the business organization of CIB and each of its subsidiaries,
to keep available the services of its and their present key officers and
employees and to preserve the goodwill of those having business relationships
with CIB or its subsidiaries. In addition, the Merger Agreement restricts CIB
and its subsidiaries from engaging in certain transactions during the interim
period from July 25, 1994 to the Effective Time, unless approved in writing by
NCC, including, among other things, (a) incurring any indebtedness for borrowed
money (other than in the ordinary course of business consistent with past
practice or short term indebtedness incurred to refinance short term
indebtedness and indebtedness of CIB or any of its subsidiaries), assuming,
guaranteeing, endorsing or otherwise as an accommodation becoming responsible
for the obligations of any other person or entity, or making any loan or
advance, other than in the ordinary course of business consistent with past
practice; (b) making any change or amendment to their respective articles of
incorporation or by-laws (or comparable governing instruments); (c) issuing or
selling any shares of capital stock or any other securities (other than pursuant
to the exercise of stock options outstanding as of July 25, 1994 issued under
the CIB Option Plans) or issuing any securities convertible into or exchangeable
for, or options, warrants to purchase, scrip, rights to subscribe for, calls or
commitments of any character whatsoever relating to, or entering into any
contract, understanding or arrangement with respect to the issuance of, any
shares of capital stock or any other securities of any of the foregoing or
entering into any arrangement or contract with respect to the purchase or voting
of shares of their capital stock, or adjusting, splitting, combining or
reclassifying any of their capital stock or other securities or making any other
changes in their capital structures; (d) granting any additional options under
any CIB Option Plans; (e) declaring, setting aside, paying or making any
dividend or other distribution or payment (whether in cash, stock or property)
with respect to, or purchasing or redeeming, any shares of their capital stock,
other than (i) regular quarterly cash dividends on CIB Common in an amount not
to exceed $0.1275 per share of CIB Common for the quarter ending September 30,
1994, not to exceed $0.1325 per share of CIB Common for the quarter ending
December 31, 1994 and not to exceed $0.1375 per share of CIB Common for the
quarter March 31, 1995 or later (the parties agreeing that they will cooperate
so that there will not be any duplication or omission of a dividend payment to
CIB shareholders during any quarter) and (ii) dividends paid by any CIB
subsidiary to another CIB subsidiary or CIB with respect to its capital stock
between July 25, 1994 and the Effective Time; (f) adopting or amending (except
as required by law or amending existing employment contracts to provide for a
June 30, 1997 termination date) any bonus, profit sharing, compensation,
severance, termination, stock option, pension, retirement, deferred
compensation, employment, welfare benefit or other employee benefit agreements,
trusts, plans, funds 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) increasing the
compensation or fringe benefits of any director, officer or employee or paying
any benefit not
 
                                       26
<PAGE>   30
 
required by any existing plan or arrangement (including, without limitation, the
granting of stock options or stock appreciation rights) or taking any action or
granting any benefit not required under the terms of any existing agreements,
trusts, plans, funds or other such arrangements or entering into any contract,
agreement, commitment or arrangement to do any of the foregoing.
 
     Certain Policies. The Merger Agreement requires CIB to 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; provided, however,
that CIB shall not be required to modify or change any such policies or
practices until (a) such time as NCC acknowledges that all conditions to its
obligation to consummate the Merger have been waived or satisfied and (b)
immediately prior to the Effective Time. CIB's representations, warranties or
covenants contained in the Merger 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. CIB does not currently anticipate that such changes or
modifications, assuming the Merger is consummated during the fourth calendar
quarter of 1994, will in the aggregate result in any material change in the
valuation of CIB's assets.
 
     Acquisition Proposals. The Merger Agreement provides that each of CIB and
its subsidiaries shall not, and shall instruct and otherwise use its best
efforts to cause their respective officers, directors, employees, agents or
advisors or other representatives or consultants not to, directly or indirectly,
(a) solicit or initiate any proposals or offers from any other person or entity
relating to any acquisition or purchase of all or a material amount of the
assets of, or any securities of, or any merger, consolidation or business
combination with, CIB or any of its subsidiaries (each such transaction an
"Acquisition Event") or (b) except to the extent that the Board of Directors of
CIB is required in the exercise of its fiduciary duties in accordance with
applicable law (based on the written advice of its legal counsel), participate
in any discussions or negotiations regarding, or furnish to any other person or
entity any information with respect to, an Acquisition Event. CIB has agreed to
cease any existing activities, discussions or negotiations with any other
parties conducted prior to the execution of the Merger Agreement with respect to
any Acquisition Event. CIB has agreed to notify NCC immediately if any such
inquiries or proposals are received by, any such information is requested from,
or any such negotiations or discussions are sought to be initiated or continued
with, CIB.
 
INTEREST OF MANAGEMENT IN THE MERGER
 
EMPLOYEE MATTERS
 
     The Agreement provides that upon consummation of the Merger, NCC shall
honor, on and after the Effective Time, without deduction, counterclaims,
interruptions or deferment (other than withholding under applicable law), all
vested benefits of any person under all of CIB's employee plans or agreements.
Moreover, former CIB and Kokomo employees will be provided direct compensation
and fringe benefits, including NCC's "Flex" program and 401(k) Savings and
Investment Plan, on terms no less favorable than those benefits provided to
other employees of National City Bank, Indiana ("NCB").
 
     NCC will assume, and NCB will guarantee, the existing employment agreements
between Kokomo and Robert J. Heltzel, Donald L. McCauley, Timothy A. Renie and
James E. Fritz, four of CIB's executive officers. Those employment agreements
will be amended prior to the Effective Date to provide for termination dates of
June 30, 1997, and will not be renewed thereafter.
 
     Under the employment agreements, the employee receives an initial salary
equal to his current salary, subject to increases approved by CIB's Board of
Directors. The employee may terminate his employment upon sixty days' written
notice to his employer. The employer may discharge the employee for "cause" (as
defined in the contract) at any time or in certain events specified by OTS
regulations. If the employer terminates the employee's employment for other than
"cause" or if the employee terminates his own employment for "cause" (as defined
in the contract), the employee will receive his base compensation under the
contract (a) for an additional three years if the termination follows a change
of control, or (b) for the remaining term of the contract if the termination
does not follow a change of control. Moreover, within a period of three months
after such termination following a change of control, the employee will have the
right to cause his employer to purchase any stock options he holds for a price
equal to the fair market value (as defined in the contract) of the shares
subject
 
                                       27
<PAGE>   31
 
to such options minus their option price. The term "change of control" does not
include an acquisition approved in advance by CIB's Board of Directors.
 
     Upon the Effective Time, NCB will assume, and NCC will guarantee, all
obligations of CIB and Kokomo to former officers, directors and employees of
First Federal Savings and Loan Association of Peru ("Peru"), and their spouses,
set forth in the Merger Agreement dated September 8, 1993, among CIB, Kokomo and
Peru (the "Peru Merger Agreement") 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 the Peru Merger Agreement, as though NCB
were a party thereto.
 
     Upon consummation of the merger of Kokomo into NCB, each of CIB's current
directors will become an advisory director of NCB's Logansport, Kokomo and Peru
branch operations and will continue to serve as such, subject to physical and
mental fitness, as long as he is willing to do so until reaching age 70. As
advisory directors, they shall be paid the same fees they are currently earning
as directors of CIB, subject to inflationary or merit increases made at NCB's
discretion. Fred McClung, an advisory director of Kokomo, will also become an
advisory director of NCB and shall serve as such until December 31, 1995,
receiving 90% of the advisory director fees paid to CIB's directors following
the merger of Kokomo into NCB.
 
     Kokomo's Financial Institutions Retirement Fund will be terminated and
frozen as of the Effective Time and all employees of CIB and Kokomo at the
Effective Time will be eligible to participate in NCC's retirement plan,
receiving credit for past service for vesting and eligibility purposes under
that NCC plan. Participants will be given the opportunity to roll their fully
vested accounts under Kokomo's Financial Institutions Retirement Fund into NCC's
401(k) Savings and Investment Plan or to continue to participate in the frozen
thrift plan. Past service credit for vesting and eligibility will be provided to
former CIB and Kokomo employees under NCC's 401(k) Savings and Investment Plan.
 
     The 12 employees of Kokomo who have attained age 55 and have at least 15
years of services with CIB or Kokomo (including two executive officers of CIB)
will be provided a cash payment equal to the actuarial equivalent present value
of the increased benefits such employees would have received under Kokomo's
Financial Institutions Retirement Fund had it remained in effect for three years
following the Effective Time (taking into account any cost of living payments
which would have accrued with respect to the increased payments provided in
Kokomo's Financial Institutions Retirement Fund) reduced by the actuarial
equivalent present value of the projected benefit to be received by such
employees for participation in the NCC retirement plan during such 3-year
period.
 
     CIB's Employee Stock Purchase Plan will be terminated at the Effective Time
or shortly thereafter, and benefits paid out in accordance with the terms of
that plan.
 
     Any employees of CIB or Kokomo not retained by NCC or its subsidiaries
following the Merger will be entitled to severance pay pursuant to NCC severance
pay programs.
 
     NCC's group insurance program will be provided to former CIB and Kokomo
employees and to present and specified future retirees to the extent such
retirees were entitled to such insurance under arrangements of CIB or Kokomo in
effect at the time the Merger Agreement was executed.
 
     Deferred directors' fees held in accounts of Kokomo for former CIB director
Fred McClung and current CIB director, Stephen A. Kiley, will be held in similar
accounts by NCB following the Effective Time, will continue to accrue interest
as provided in CIB's Unfunded Deferred Compensation Plan and will be paid out in
accordance with the terms of such Plan (although in Mr. Kiley's case, those fees
will become payable when he ceases to be an advisory director of NCB).

INDEMNIFICATION AND INSURANCE
 
     The Merger Agreement provides that, from and after the Effective Time, NCC
will assume and honor any obligation of CIB immediately prior to the Effective
Time with respect to the indemnification of each person who was on July 25,
1994, or has been at any time prior to July 25, 1994, or who becomes prior to
the Effective Time, a director or officer of CIB or any of its subsidiaries or
was serving at the request of CIB as a director, officer of any domestic or
foreign corporation, joint venture, trust, employee benefit plan or other
enterprise (collectively, the "Indemnitees") arising out of CIB's Articles or
CIB's By-Laws or any indemnification (to the maximum extent available
thereunder) 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
CIB or any of its subsidiaries. The Merger Agreement further provides that, for
a period of two years after the Effective Time, NCC will provide to the officers
and directors of CIB directors and officers insurance coverage (up to
$20,000,000) with respect to claims not known by CIB prior to the Effective Date
but which arise from factors or events which occur before the Effective Time.
Following the Effective Time, NCB will provide CIB and CIB Subsidiary employees
who become officers of NCB with the same directors and officers liability
coverage and indemnification that NCB provides to other NCB officers.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Pursuant to the terms of the Merger Agreement, NCC and CIB have received
the opinion of Barnes & Thornburg to the effect that, on the basis of facts,
representations and assumptions set forth in such opinion or contained in this
Prospectus and Proxy Statement or certificates of officers of CIB and NCC
(including, among others, representations that (a) to the best knowledge of CIB,
there is no agreement or plan on the part of the shareholders of CIB to dispose
of any shares of NCC Common received in the Merger, (b) there is no agreement or
plan for NCC to reacquire any of the NCC Common issued pursuant to the Merger,
and (c) there is no agreement or plan on the part of NCC's management to dispose
of any significant assets of CIB after the Merger other than the contemplated
merger of Kokomo into NCB, 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, for United States federal income tax purposes:
 
          (i) no gain or loss will be recognized by NCC or CIB as a result of
     the Merger;
 
          (ii) no gain or loss will be recognized by shareholders of CIB who
     exchange their shares of CIB Common solely for shares of NCC Common
     pursuant to the Merger (except with respect to cash received in lieu of a
     fractional share interest in NCC Common);
 
          (iii) the tax basis of shares of NCC Common received by shareholders
     of CIB who exchange all of their shares of CIB Common solely for shares of
     NCC Common in the Merger will be the same as the tax basis of the shares of
     CIB Common surrendered in exchange therefor (reduced by any amount
     allocable to a fractional share interest for which cash is received); and
 
          (iv) the holding period of the shares of NCC Common received in the
     Merger will include the period during which the shares of CIB Common
     surrendered in exchange therefor were held, provided such shares of CIB
     Common were held as capital assets at the Effective Time.
 
     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS BASED UPON CURRENT
LAW. SUCH DISCUSSION MAY NOT BE APPLICABLE TO A CIB SHAREHOLDER WHO ACQUIRED
SHARES OF CIB COMMON PURSUANT TO THE EXERCISE OF AN EMPLOYEE STOCK OPTION OR
OTHERWISE AS COMPENSATION. EACH CIB SHAREHOLDER IS URGED TO CONSULT HIS OR HER
OWN TAX ADVISOR CONCERNING THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO SUCH
SHAREHOLDER, INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL AND
OTHER TAX LAWS AND ANY PROPOSED CHANGES IN SUCH TAX LAWS.

ACCOUNTING TREATMENT
 
     The Merger, if completed as proposed, will be treated as a purchase for
accounting and financial reporting purposes. Under the purchase method of
accounting, all identifiable tangible and intangible assets and liabilities of
CIB will be recorded by NCC at their respective fair values at the Effective
Time of the Merger as determined solely by NCC from its perspective as the
purchaser of those assets. The expected excess of the consideration paid by NCC
at the Effective Time over the fair value of CIB's tangible and intangible
assets as adjusted by NCC less the liabilities will be accounted for as
goodwill, and will be amortized over 20 years. See "PRO FORMA COMBINED
CONSOLIDATED FINANCIAL INFORMATION."
 
RESALES BY AFFILIATES
 
     The shares of NCC Common issued to CIB shareholders pursuant to the Merger
Agreement will have been registered under the Securities Act of 1933, as amended
(the "1933 Act"), but such registration does not cover resales by shareholders
of CIB who may be deemed to be "affiliates" of CIB, as that term is used in
paragraphs (c) and (d) of Rule 145 promulgated under the 1933 Act.
 
APPRAISAL AND DISSENTERS' RIGHTS
 
     NCC.  Because NCC Common is listed on the NYSE and is held of record by
more than 2,000 stockholders, and because no vote of the holders of NCC Common
is required for approval of the Merger, stockholders of NCC are not entitled to
appraisal or dissenters' rights under the DGCL in connection with the Merger.
 
     CIB.  Section 23-1-44-8(b) of the IBCL provides that no dissenters' rights
under the IBCL shall be available for the holders of shares of any class or
series if, on the date fixed to determine the shareholders entitled to receive
notice of and vote at the meeting of shareholders at which a merger, plan of
share exchange, or sale or exchange of property is to be acted on, the shares of
that class or series were registered on a United States securities exchange
registered under the Securities Exchange Act of 1934, as amended (the "Exchange
Act") or traded on NASDAQ or a similar market. Because CIB Common is traded on
NASDAQ, shareholders of CIB are not entitled to appraisal or dissenters' rights
in connection with the Merger.
 
THE OPTION
 
     As a condition to NCC's entering into the Merger Agreement, and in
consideration therefor, CIB entered into the Option Agreement, pursuant to which
CIB granted NCC the Option on July 25, 1994. The Option Agreement is intended to
increase the likelihood that the Merger will be consummated by making it more
difficult and more expensive for another party to obtain control of or acquire
CIB.
 
     Grant of Option.  The Option entitles NCC to purchase up to 326,000 fully
paid and non-assessable shares of CIB Common, representing 19.9% of the shares
of CIB Common issued and outstanding as of July 25, 1994 without giving effect
to any shares subject or issued pursuant to the Option, at a price of $28.75 per
share; provided, however, that in the event CIB issues or agrees to issue any
shares of CIB Common (other than as permitted pursuant to the CIB Option Plans
as provided under the Agreement) at a price less than $28.75 per share (as
adjusted as described below), such price shall be equal to such lesser price
(such price, as adjusted if applicable, the "Option Price"); provided further,
that in no event may the number of shares for which the Option is exercisable at
any time exceed 19.9% of the issued and outstanding shares of CIB Common without
giving effect to any shares subject or issued pursuant to the Option. The
aggregate purchase price for the shares of CIB Common that may be purchased upon
the exercise of the Option at the original Option Price is $9,372,500.
 
     Triggering Events; Exercise of Option.  The Option Agreement provides that
NCC may exercise the Option, in whole or in part, if both an Initial Triggering
Event (as defined below) and a Subsequent Triggering Event (as defined below)
shall have occurred prior to the occurrence of an Exercise Termination Event (as
defined below), provided that NCC shall have sent to CIB written notice of such
exercise within 30 days following such Subsequent Triggering Event (or such
later date as is necessary to obtain all regulatory approvals for the exercise
 
                                       30
<PAGE>   34
 
of the Option and for the expiration of all statutory waiting periods, and to
avoid liability under Section 16(b) of the Exchange Act by reason of such
exercise).
 
     For purposes of the Option Agreement:
 
     (a) The term "Initial Triggering Event" means any of the following events
or transactions occurring after July 25, 1994:
 
          (i) CIB, or any of its subsidiaries, without having received NCC's
     prior written consent, shall have entered into an agreement to engage in an
     Acquisition Transaction (as defined below) with any person (the term
     "person" for purposes of the Option Agreement having the meaning assigned
     thereto in Sections 3(a)(9) and 13(d)(3) of the Exchange Act and the rules
     and regulations promulgated thereunder), or the Board of Directors of CIB
     shall have recommended that the shareholders of CIB approve or accept any
     Acquisition Transaction other than the Merger. For purposes of the Option
     Agreement, the term "Acquisition Transaction" means (A) a merger or
     consolidation, or any similar transaction, involving CIB or its thrift
     subsidiary (the "Significant Subsidiary"), (B) a purchase, lease or other
     acquisition of all or substantially all of the assets of CIB or the
     Significant Subsidiary, or (C) 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 CIB or the Significant
     Subsidiary; provided, however, the term "Acquisition Transaction"
     specifically does not include any merger or consolidation among CIB and/or
     its subsidiaries;
 
          (ii) The Board of Directors of CIB does not recommend that the
     shareholders of CIB approve the Articles Amendment or the Merger Agreement;
 
          (iii) Any person other than NCC, any stockholder of NCC who, at July
     25, 1994, beneficially held 10% or more of the outstanding shares of NCC
     Common, any subsidiary of NCC or any subsidiary of CIB 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
     CIB Common (the term "beneficial ownership" for purposes of the Option
     Agreement having the meaning assigned thereto in Section 13(d) of the
     Exchange Act and the rules and regulations promulgated thereunder);
 
          (iv) Any person other than NCC or any subsidiary of NCC shall have
     made a bona fide proposal to CIB 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 CIB or its
     shareholders to engage in an Acquisition Transaction, CIB shall have
     breached any covenant or obligation contained in the Merger Agreement and
     such breach (A) would entitle NCC to terminate the Merger Agreement and (B)
     shall not have been cured prior to the date of the notice of the exercise
     of the Option; or
 
          (vi) Any person other than NCC or any subsidiary of NCC, other than in
     connection with a transaction to which NCC has given its prior written
     consent, shall have filed an application with the FRB or other governmental
     agency for approval to engage in an Acquisition Transaction.
 
     (b) The term "Subsequent Triggering Event" means either of the following
events or transactions occurring after July 25, 1994:
 
          (i) The acquisition by any person of beneficial ownership of 15% or
     more of the then outstanding shares of CIB Common other than by any person
     who, at July 25, 1994, beneficially owned more than 15% of the outstanding
     shares of CIB Common; or
 
          (ii) The occurrence of the Initial Triggering Event described above in
     clause (a)(i), except that the percentage referred to in subclause
     (a)(i)(C) shall be 15%.
 
     (c) Each of the following events constitutes an "Exercise Termination
Event":
 
          (i) immediately prior to the Effective Time;
 
          (ii) termination of the Merger Agreement in accordance with the
     provisions thereof if such termination occurs prior to the occurrence of an
     Initial Triggering Event; or
 
                                       31
<PAGE>   35
 
          (iii) the passage of nine months after termination of the Merger
     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. For purposes of the Option Agreement, the term "Last
     Triggering Event" means the last Initial Triggering Event to occur.
 
As of the date hereof, no Initial Triggering Event or Subsequent Triggering
Event has occurred.
 
     The Merger Agreement may be terminated at any time prior to the Effective
Time by either NCC or CIB if the Merger is not approved at the Special Meeting
of Shareholders of CIB (provided that the terminating party is not otherwise in
material breach of its obligations under the Agreement). Accordingly, if no
Initial Triggering Event has occurred, in the event that the CIB shareholders do
not approve the Merger Agreement at the Special Meeting, and either NCC or CIB
terminates the Merger Agreement as a result thereof, the Option shall terminate.
 
     In the event of any change in CIB Common by reason of a stock dividend,
split-up, merger, recapitalization, combination, subdivision, conversion,
exchange of shares or similar transaction, the type and number of shares of CIB
Common subject to the Option and the purchase price therefor will be adjusted
appropriately.
 
     Whenever the number of shares of CIB Common purchasable upon exercise of
the Option is adjusted as provided in the preceding paragraph, 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 CIB Common purchasable prior
to the adjustment and the denominator of which shall be equal to the number of
shares of CIB Common purchasable after the adjustment.
 
     Repurchase of Option. Upon the occurrence of a Subsequent Triggering Event
that occurs prior to an Exercise Termination Event, at the request of NCC,
delivered within 30 days of the Subsequent Triggering Event (or such later date
as is necessary to obtain all regulatory approvals and for the expiration of all
statutory waiting periods, and to avoid liability under Section 16(b) of the
Exchange Act), CIB (a) shall repurchase the Option from NCC at a price (the
"Option Repurchase Price") equal to (i) 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 the Option may then be exercised, plus (ii) NCC's
Out-of-Pocket Expenses (as defined below) (to the extent not previously
reimbursed) and (b) shall repurchase such number of shares of CIB Common issued
upon total or partial exercise of the Option (the "Option Shares") from NCC as
NCC shall designate at a price (the "Option Share Repurchase Price") equal to
(i) the market/offer price multiplied by the number of Option Shares so
designated plus (ii) NCC's Out-of-Pocket Expenses (to the extent not previously
reimbursed).
 
     For purposes of the Option Agreement:
 
     (a) The term "Out-of-Pocket Expenses" means NCC's reasonable out-of-pocket
expenses incurred in connection with the transactions contemplated by the Merger
Agreement, including, without limitation, legal, accounting and investment
banking fees.
 
     (b) The term "market/offer price" means the highest of
 
          (i) the price per share of CIB Common at which a tender offer or
     exchange offer therefor has been made after July 25, 1994;
 
          (ii) the price per share of CIB Common to be paid by any third party
     pursuant to an agreement with CIB;
 
          (iii) the highest closing price for shares of CIB Common within the
     30-day period immediately preceding the date NCC gives notice of the
     required repurchase of the Option or the Option Shares, as the case may be;
     or
 
          (iv) in the event of a sale of all or substantially all of CIB's
     assets, the sum of the price paid in such sale for such assets and the
     current market value of the remaining assets of CIB as determined by a
     nationally recognized investment banking firm selected by NCC, divided by
     the number of shares of CIB Common outstanding at the time of such sale. In
     determining the market/offer price, the value of
 
                                       32
<PAGE>   36
 
     consideration other than cash will be determined by a nationally recognized
     investment banking firm selected by NCC, whose determination will be
     conclusive and binding on all parties.
 
     Substitute Option. The Option Agreement provides that in the event that
prior to an Exercise Termination Event, CIB enters into an agreement (a) to
consolidate or merge with any person, other than NCC or one of its subsidiaries,
and CIB is not the continuing or surviving corporation of such consolidation or
merger, (b) to permit any person, other than NCC or one of its subsidiaries, to
merge into CIB and CIB is the continuing or surviving corporation, but, in
connection with such merger, the then outstanding shares of CIB Common are
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 CIB Common after
such merger represent less than 50% of the outstanding shares and share
equivalents of the merged company, or (c) to sell or otherwise transfer all or
substantially all of its assets to any person, other than NCC or one of its
subsidiaries, then, and in each such case, the agreement governing such
transaction must make proper provision so that the Option shall, upon the
consummation of any such transaction, be converted into, or exchanged for, an
option (the "Substitute Option"), at the election of NCC, of either (i) the
Acquiring Corporation (as defined below) or (ii) any person that controls the
Acquiring Corporation. For purposes of the Option Agreement, the term "Acquiring
Corporation" means (A) the continuing or surviving corporation of a
consolidation or merger with CIB (if other than CIB), (B) CIB in a merger in
which CIB is the continuing or surviving corporation, and (C) the transferee of
all or substantially all of CIB's assets.
 
     The Substitute Option shall have the same terms as the Option; provided,
however, 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 NCC. The Option Agreement provides that CIB may not
enter into any transaction described above triggering a Substitute Option unless
the Acquiring Corporation and any person that controls the Acquiring Corporation
assumes in writing all the obligations of CIB under the Option Agreement. The
Option Agreement further provides that the issuer of the Substitute Option shall
enter into an agreement with NCC in substantially the same form as the Option
Agreement, which agreement shall be applicable to the Substitute Option and
shall provide for the repurchase of the Substitute Option and any shares of the
issuer issued pursuant thereto on terms similar to the repurchase of the Option
and the Option Shares.
 
     The Substitute Option will be exercisable for such number of shares of
common stock of the issuer of the Substitute Option ("Substitute Common Stock")
as is equal to the market/offer price multiplied by the number of shares of CIB
Common for which the Option is then exercisable, divided by the Average Price.
For purposes of the Option Agreement, the term "Average Price" means the average
closing price of a share of 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 a share of Substitute Common Stock on the day
preceding such consolidation, merger or sale; provided, however, that if CIB is
the issuer of the Substitute Option, the Average Price will be computed with
respect to a share of common stock issued by the person merging into CIB or by
any company which controls or is controlled by such person, as NCC may elect.
The exercise price of the Substitute Option per share of Substitute Common Stock
will then be equal to the Option Price multiplied by a fraction, the numerator
of which will be the number of shares of CIB Common for which the Option is then
exercisable and the denominator of which will be the number of shares of
Substitute Common Stock for which the Substitute Option is exercisable.
 
     The Option Agreement provides that the Substitute Option may not 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, the issuer of the
Substitute Option will be required to make a cash payment to NCC equal to the
excess of (a) the value of the Substitute Option without giving effect to the
foregoing limitation over (b) the value of the Substitute Option after giving
effect to the foregoing limitation. Such difference in value will be determined
by a nationally recognized investment banking firm selected by NCC.
 
     Registration Rights. Within 30 days after the occurrence of a Subsequent
Triggering Event (or such later date as is necessary to obtain all regulatory
approvals and for the expiration of all statutory waiting periods, and to avoid
liability under Section 16(b) of the Exchange Act), NCC may request CIB to
prepare and file a registration statement with the Commission if such
registration is necessary to permit the sale or other disposition of the shares
of CIB Common purchased upon exercise of the Option. CIB is required to use its
best efforts to
 
                                       33
<PAGE>   37
 
cause such registration statement to become effective and then to remain
effective for 180 days or such shorter time as may be reasonably necessary to
effect such sales or dispositions. NCC has the right to demand two such
registrations. CIB also will permit NCC to include the sale of some or all
shares of CIB Common purchased upon exercise of the Option in certain
registration statements initiated by CIB.
 
     Assignment of Option. Neither NCC nor CIB may assign any of its rights or
obligations under the Option Agreement or the Option to any other person without
the express written consent of the other party, except that in the event a
Subsequent Triggering Event occurs prior to an Exercise Termination Event, NCC
may assign, in whole or in part, its rights and obligations under the Option
Agreement or the Option within 30 days following such Subsequent Triggering
Event (or such later date as is necessary to obtain all regulatory approvals and
for the expiration of all statutory waiting periods, and to avoid liability
under Section 16(b) of the Exchange Act); provided, however, that until the date
30 days following the date at which the FRB approves an application by NCC under
the BHCA to acquire the shares of CIB Common subject to the Option, NCC may not
assign its rights under the Option except in (a) a widely dispersed public
distribution, (b) a private placement in which no one party acquires the right
to purchase in excess of 2% of the voting shares of CIB, (c) an assignment to a
single party (e.g., a broker or investment banker) for the purpose of conducting
a widely dispersed public distribution on NCC's behalf, or (d) any other manner
approved by the FRB.
 
     Termination of Option. The option will terminate upon the occurrence of an
Exercise Termination Event. In the event that the holder of the Option or the
owner of Option Shares or any affiliate thereof is a person making an offer or
proposal to engage in an Acquisition Transaction (other than the Merger), then
(a) in the case of a holder of the Option or any affiliate thereof, the Option
held by it will immediately terminate, and (b) in the case of an owner of Option
Shares or any affiliate thereof, the Option Shares held by it will be
immediately repurchasable by CIB at the Option Price.
 
     Additional Provisions. Certain rights and obligations of NCC and CIB under
the Option Agreement are subject to receipt of required regulatory approvals.
Among other things, the approval of the FRB is required for the acquisition by
NCC of more than 5% of the outstanding shares of CIB Common. Accordingly, an
application for FRB approval of the exercise of the Option has been filed as
part of the application referred to on page 65 above. Article 11 of CIB's
Articles of Incorporation prohibits any person from acquiring over 10% of CIB's
outstanding shares of Common Stock, subject to certain limited exceptions.
Shares acquired in violation of this provision may not be voted.
 
     State Takeover Law. Under the IBCL, without prior approval of its board of
directors, an issuing public corporation is prohibited from engaging in any
"business combination" with an "interested shareholder" for a five-year period
after the date upon which the shareholder attains this status. See "GENERAL
COMPARISON OF NCC AND CIB CAPITAL STOCK -- Antitakeover Statutes -- Indiana
Business Combination Statute." Neither the grant nor the exercise of the Option
has made (or would make) NCC subject to this five-year prohibition because CIB's
Board of Directors approved NCC becoming an "interested shareholder" by reason
of the Option and the grant of the Option to NCC prior to the date of the
granting of the Option.
 
     Indiana law also restricts the voting rights of "control shares" acquired
in a "control share acquisition" to those voting rights granted by a resolution
approved by a majority of the outstanding voting shares excluding certain
"interested shares." See "GENERAL COMPARISON OF NCC AND CIB CAPITAL STOCK --
Antitakeover Statutes -- Indiana Control Share Acquisitions Statute." The
application of the Indiana Control Share Acquisitions Statute were to be
reinstated and NCC exercises the Option and purchases 326,000 shares of CIB
Common, representing 19.9% of the shares of CIB Common issued and outstanding as
of July 25, 1994, such acquisition would not fall within the minimum range
(which begins at 20%) resulting in the restriction of voting rights under this
statute.

     The unaudited financial information on the following pages presents (a) the
historical consolidated balance sheets of both NCC and CIB at September 30, 1994
and the pro forma condensed combined consolidated balance sheet as of September
30, 1994, giving effect to the Merger as if it had occurred on that date; and
(b) the historical consolidated statements of income of both NCC and CIB and the
pro forma condensed combined consolidated statements of income for the nine
months ended September 30, 1994 and the year ended December 31, 1993, giving
effect to the Merger as if it had occurred at January 1, 1993.
 
     The financial information assumes all of the outstanding shares of CIB
Common are converted into shares of NCC Common. The pro forma information is
based on the historical financial statements, giving effect to the Merger under
the purchase method of accounting. The pro forma statements do not reflect any
direct costs or potential savings which may result from the consolidation of the
operations of CIB and NCC, and may not be indicative of the results that
actually would have occurred had the Merger been consummated on the dates
indicated, or which may be attained in the future.

         NOTES TO PRO FORMA CONSOLIDATED COMBINED FINANCIAL STATEMENTS
 
(1) CIB has a September 30 fiscal year. In accordance with Regulation S-X, Rule
    3A-02(b)(1), the CIB results of operations for the year ended September 30,
    1993 have been combined with the results of NCC for the year ended December
    31, 1993 for purposes of preparing a pro forma statement of income for the
    year ended December 31, 1993. For the nine months ended September 30, 1994,
    the CIB fiscal 1994 results were adjusted to exclude the first quarter
    activity (ended December 31, 1993) for purposes of preparing a pro forma
    statement of income for the nine months ended September 30, 1994. The
    December 31, 1993 pro forma statement of income also includes the results of
    First Federal Savings and Loan Association of Peru ("Peru"), which was
    acquired by CIB in January 1994.
 
    In January 1994, CIB completed the acquisition of Peru in a purchase
    transaction. Prior to the acquisition, Peru was a mutual federal savings and
    loan association and reported on a calendar year basis. In the acquisition
    CIB issued 175,825 of its common shares to the owners of Peru. For purposes
    of preparing a pro forma statement of income for the year ended December 31,
    1993, the Peru results have been added to NCC and CIB, and the shares of CIB
    issued in the transaction have been adjusted for the Exchange Ratio in the
    proposed acquisition of CIB by NCC. The pro forma results of operations for
    the nine months ended September 30, 1994 do not show a separate Peru
    contribution as this entity is included in CIB for that period.
 
(2) The pro forma statement of income for the nine months ended September 30,
    1994 excludes the change in accounting for income taxes and post retirement
    benefits originally reported by CIB, as required by the Commission's
    Regulation S-X.
 
(3) The following is an explanation of the pro forma accounting adjustments
    included in the September 30, 1994 pro forma balance sheet:
 
   - The CIB balance sheet is recorded at fair value as required under APB
     Opinion No. 16. As such, securities and loans are recorded at their
     estimated fair values. The ultimate fair values of all assets and
     liabilities will be determined at the closing of the transaction.
 
   - The acquisition of Peru by CIB was completed in January 1994, and as such
     the accounts of Peru are already included in CIB at September 30, 1994.
 
   - Negative goodwill of $3.9 million from the Peru acquisition has been
     written off in purchase accounting.
 
   - Expenses of the transaction totalling $2.6 million have been accrued in the
     pro forma balance sheet.
 
   - A tax liability of $2.1 million has been accrued into the opening balance
     sheet to recognize taxes that will become due upon the conversion of CIB
     from a federal savings bank to a national bank. The taxes relate to
     preferential treatment allotted to the provision for loan losses for
     savings banks that is not available to commercial banks.
 
   - The CIB Capital Surplus and retained earnings have been eliminated in the
     pro forma balance sheet.
 
(4) The following is the calculation of payment for the acquisition of CIB by
    NCC. The calculation assumes a market value for NCC Common of $26.50 per
    share. The actual transaction value will be determined at the date of
    closing.

(5) The pro forma adjustments to the statements of income represent the
    amortization of goodwill (over 20 years) and other purchase accounting
    adjustments as if the acquisition had been consummated on January 1, 1993.
    These adjustments are not materially different from the adjustments that
    would arise based upon a September 30, 1994 acquisition date.

                             INFORMATION ABOUT CIB
 
     CIB was incorporated under the laws of the State of Indiana and became a
unitary savings and loan holding company upon conversion on July 1, 1991 of
Kokomo from a federal mutual savings bank to a federal stock savings bank. The
principal asset of CIB consists of 100% of the issued and outstanding shares of
common stock, $.01 par value per share, of Kokomo.
 
     Kokomo is the second largest financial institution headquartered in Howard
County, while two banks operating in Howard County have greater total deposits.
Kokomo is one of the leading residential mortgage lenders in Howard County, with
a significant share of the market for residential construction mortgage loans.
 
     Kokomo's principal business is to attract deposits from the general public
and to originate mortgage loans secured primarily by one-to-four family
residential real property in Howard County and surrounding counties. In
addition, in recent years Kokomo has emphasized home equity loans and consumer
loans such as installment loans, auto loans, home improvement loans, loans
secured by deposits, and education loans. Kokomo also makes multi-family,
non-residential real estate, and residential and development and construction
loans, as well as other secured and unsecured commercial loans. Kokomo derives
most of its funds for its lending from deposits of its customers consisting
primarily of savings accounts, checking account and certificates of deposit. It
also offers, indirectly through its service corporation subsidiary, tax-deferred
annuities, on an agency basis.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
 
GENERAL
 
     CIB's principal business has historically consisted of attracting deposits
from the general public and making loans secured by residential and other real
estate. CIB is significantly affected by prevailing economic conditions, as well
as by government policies and regulations concerning, among other things,
monetary and fiscal affairs, housing and financial institutions. Deposit flows
are influenced by a number of factors, including interest rates paid on
competing investments, account maturities and level of personal income and
savings. In addition, deposit growth is also affected by how customers perceive
the stability of the financial services industry amid various current events
such as regulatory changes, failures of other thrifts and financing of the
deposit insurance fund. Lending activities are influenced by the demand for and
supply of housing lenders, the availability and cost of funds and various other
items. Sources of funds for lending activities include deposits, payments on
loans, proceeds from sales of loans, borrowings, and funds provided from
operations.
 
     CIB's earnings are primarily dependent upon Kokomo's net interest income,
the difference between interest income and interest expense. Interest income is
a function of the balance of loans and investments outstanding during a given
period and the yield earned on such loans and investments. Interest expense is a
function of the amounts of deposits and borrowings outstanding during the same
period and the rates paid on such deposits and borrowings. Kokomo's earnings are
also affected by gains and losses on sales of loans and investments, provisions
for loan losses, service charges, income from subsidiary activities, operating
expenses and income taxes.
 
     On an annual basis, CIB updates its strategic business plan. This plan
includes, among other things, CIB's commitment to maintaining a strong capital
base and continuing to improve the organization's return on assets. Continued
careful monitoring of CIB's interest rate risk is also cited as an important
goal. As a result, continued origination of short-term commercial and
installment loans as well as adjustable rate mortgage loans is planned, with
fixed-rate real estate loans with original terms in excess of 10 years,
underwritten to secondary market standards, being sold or held for sale.
 
ASSET/LIABILITY MANAGEMENT
 
     Kokomo like other financial institutions, is subject to interest rate risk
to the extent that its interest-bearing liabilities with short and
intermediate-term maturities reprice more rapidly, or on a different basis, than
its interest-earning assets. Management of Kokomo believes it is critical to
manage the relationship between interest rates and the effect on Kokomo's net
portfolio value ("NPV"). This approach calculates the difference between the
present value of expected cash flows from assets and the present value of
expected cash flows from liabilities, as well as cash flows from off-balance
sheet contracts. Management of Kokomo's assets and liabilities is done within
the context of the marketplace, regulatory limitations and within limits
established by the Board of Directors on the amount of change in NPV which is
acceptable given certain interest rate changes.
 
     The Office of Thrift Supervision ("OTS") recently issued a regulation,
effective January 1, 1994, which uses a net market value methodology to measure
the interest rate risk exposure of thrift institutions. Under OTS regulations,
an institution's "normal" level of interest rate risk in the event of an assumed
change in interest rates is a decrease in the institution's NPV in an amount not
exceeding 2% of the present value of its assets. Beginning July 1, 1994, thrift
institutions with over $300 million in assets or less than a 12% risk-based
capital ratio are required to file OTS Schedule CMR. Data from Schedule CMR is
used by the OTS to calculate changes in net portfolio value (and the related
"normal" level of interest rate risk) based upon certain interest rate changes
(discussed below). Institutions which do not meet either of the filing
requirements are not required to file OTS Schedule CMR, but may do so
voluntarily. As Kokomo does not currently meet either of these requirements it
is not required to file Schedule CMR, but it currently does so on a voluntary
basis. Institutions which are required to file must take a deduction (the
interest rate risk capital component) from their total capital available to
calculate their risk based capital requirement if their interest rate exposure
is greater than "normal". Voluntary filers (such as Kokomo) are not subject to
an interest rate risk capital component. The amount of that deduction is
one-half of the difference between (a) the institution's actual calculated
exposure to a 200 basis point interest rate increase or decrease (whichever
results in the greater pro forma decrease in NPV) and (b) its "normal" level of
 
                                       43
<PAGE>   47
 
exposure which is 2% of the present value of its assets. Utilizing this
measurement concept, at June 30, 1994, Kokomo's interest rate risk was
considered "normal" under the OTS regulations and no additional risk-based
capital would have been required had Kokomo met the reporting requirements.
 
     Presented below, as of June 30, 1994, an analysis of Kokomo's interest rate
risk as measured by changes in NPV for instantaneous and sustained parallel
shifts in the yield curve, in 100 basis point increments, up and down 300 basis
points and compared to Board policy limits and in accordance with OTS
regulations, based on the assumptions described below. Such limits have been
established with consideration of the dollar impact of various rate changes and
Kokomo's strong capital position. As illustrated in the table, NPV is more
sensitive to rising rates than declining rates. This occurs principally because,
as rates rise, the market value of fixed-rate loans and mortgage backed
securities declines due to both the rate increase and slowing prepayments. When
rates decline, Kokomo does not experience a significant rise in market value for
these loans because borrowers prepay at relatively high rates. The value of
Kokomo's deposits and borrowings change in approximately the same proportion in
rising or falling rate scenarios.

</TABLE>
 
     In the current low rate environment, Kokomo customers are interested in
obtaining long term credit products and short term savings products. Management
has taken action to counter this trend. A significant effort has been made to
reduce the duration and average life of Kokomo's earning assets. As of June 30,
1994, 67.9% of Kokomo's gross loan portfolio consists of loans which reprice
during the life of the loan. Kokomo continually emphasizes adjustable rate
mortgages. Since the early 1980's it has been Kokomo's policy to help limit its
interest rate risk by selling the majority of its fixed-rate loans with terms of
15 years or more, so it underwrites most of these long-term fixed-rate loans to
FHLMC or FNMA specifications for sale in the secondary mortgage market. During
fiscal 1993 this policy was extended to cover most new 10 year fixed-rate
originations due to the then historically low interest rate environment. As
interest rates increased from these low levels Kokomo changed its policy, in
January 1994 to retain 10 year loans in its portfolio.
 
     With regard to deposits, management has worked to reduce the impact of
interest rate changes by emphasizing non-interesting bearing or low interest
bearing deposit products and maintaining competitive pricing on longer term
certificates of deposit.
 
     As with any method of measuring interest rate risk, certain shortcomings
are inherent in the method of analysis presented in the forgoing table. For
example, although certain assets and liabilities may have similar maturities or
periods to repricing, they may react in different degrees to changes in market
interest rates. Also, the interest rates on certain types of assets and
liabilities may fluctuate in advance of changes in market interest rates, while
interest rates on other types may lag behind changes in market rates.
Additionally, certain assets, such as ARM loans, have features which restrict
changes in interest rates on a short-term basis and over the life of the asset.
Further, in the event of a change in interest rates, expected rates of
prepayments on loans and early withdrawals from certificates could likely
deviate significantly from those assumed in calculating the table.

INTEREST RATE SPREAD
 
     CIB's results of operations have been determined primarily by net interest
income and, to a lesser extent, fee income, miscellaneous income and general and
administrative expenses. Net interest income is determined by the interest rate
spread between the yields earned on its interest-earning assets and the rates
paid on interest-bearing liabilities and by the relative amounts of
interest-earning assets and interest-bearing liabilities.
 
     The following table sets forth the weighted average effective interest rate
earned by CIB on its loan and investment portfolios, the weighted average
effective cost of CIB's deposits, the interest rate spread of CIB, and the net
yield on weighted average interest-earning assets for the periods and as of the
dates shown.

(1) Interest rate spread is calculated by subtracting combined weighted average
    interest rate cost from combined weighted average interest rate earned for
    the period indicated. Interest rate spread figures must be considered in
    light of the relationship between the amounts of interest-earning assets and
    interest-bearing liabilities. Since Kokomo's interest-earning assets
    exceeded its interest-bearing liabilities for each of the three years shown
    above, a positive interest rate spread resulted in net interest income.
 
(2) The net yield on weighted average interest-earning assets is calculated by
    dividing net interest income by weighted average interest-earning assets for
    the period indicated. No net yield figure is presented at September 30,
    1994, because the computation of net yield is applicable only over a period
    rather than at a specific date.

     The following table describes the extent to which changes in interest rates
and changes in volume of interest-related assets and liabilities have affected
Kokomo's interest income and expense during the periods indicated. For each
category of interest-earning asset and interest-bearing liability, information
is provided on changes attributable to (1) changes in rate (changes in rate
multiplied by old volume) and (2) changes in volume (changes in volume
multiplied by old rate). Changes attributable to both rate and volume which
cannot be segregated have been allocated proportionately to the change due to
volume and the change due to rate.

YEAR ENDED SEPTEMBER 30, 1994 COMPARED TO YEAR ENDED SEPTEMBER 30, 1993
 
     Financial Condition:  CIB's total assets at September 30, 1994 have
increased by $53.0 million, or 27.75%, compared to the fiscal year ended
September 30, 1993. This increase is due primarily to the merger conversion with
Peru, on January 19, 1994, which resulted in an increase in assets of $51.4
million ($48.1 million in assets of Peru after purchase accounting adjustments
and $3.3 million in net proceeds from the issuance of stock in the merger
conversion). Decreases net of the effect of the merger conversion with Peru, of
$14.4 million in interest-earning time deposits in other financial institutions,
$6.5 million in net loans receivable, $4.1 million in loans held for sale, and
$3.0 million in mortgage backed securities were used to fund an increase of
$31.6 million in investment securities and offset a net decrease of $638,000 in
deposits. Deposit growth or reduction is difficult to predict and will be
affected by the local economy, confidence of consumers in the financial services
industry, and rates paid on competing investments.
 
     The total investment securities portfolio increased from $6.6 million at
September 30, 1993 to $41.6 million at September 30, 1994. The merger conversion
of Peru added $3.4 million to total investment securities. The vast majority of
investments purchased during fiscal year 1994 were short term agency securities.
Management has completed these short-term purchases due to the negative loan
growth and the desire to maintain an acceptable level of interest rate risk.
 
     Interest-earning time deposits in other financial institutions decreased
from $16.8 million at September 30, 1993 to $6.1 million to September 30, 1994.
The merger conversion of Peru added $3.7 million to total interest-earning time
deposits in other financial institutions. Decreases in this category were the
result of yields on short term agencies exceeding amounts paid by most financial
institutions during the fiscal year and maturing funds were moved into short
term agencies.
 
     Net loans receivable increased from $134.6 million at September 30, 1993 to
$159.1 million at September 30, 1994. The merger conversion of Peru added $31.0
million in net loans. All categories of mortgage loans, with the exception of
home equity and second mortgages, increased in balance during the year.
Construction loans increased from $18.9 million at September 30, 1993 to $26.1
million at September 30, 1994. Approximately $6.2 million of the construction
loans are to individuals to fund the construction of their principal residence,
$10.4 million are for land development construction loans and $9.5 million are
to developers on a speculative basis (i.e., to a builder to finance the
construction of homes for which the builder does not have a firm purchase
commitment from a buyer). Mortgages on commercial and multi-family real estate
increased $6.8 million during the fiscal year mainly due to the addition of
Peru's portfolio. Kokomo continues to sell loans in the secondary market and had
a balance of $1.8 million in loans held for sale at September 30, 1994. These
loans were comprised of originations of fixed-rate loans with original terms in
excess of 10 years underwritten to secondary market standards. Management
intends to sell these loans, subject to market conditions, in order to decrease
its interest rate risk, particularly in view of the economic environment of low
mortgage interest rates which existed during the current fiscal year.
 
     Non-performing assets decreased approximately $74,000, or 15.81%, from
September 30, 1993, to September 30, 1994. Foreclosed real estate decreased from
$241,000 at September 30, 1993 to $0 at September 30, 1994. Troubled debt
restructurings increased from $0 at September 30, 1993 to $81,000 at September
30, 1994 and non-accrual loans increased from $227,000 at September 30, 1993 to
$313,000 at September 30, 1994.
 
     The mortgage-backed securities portfolio increased by $1.1 million.
Repayments of $7.4 million were offset by additions due to the Peru merger
conversion of $4.1 million in mortgage backed securities, and purchases of $4.2
million.
 
     General:  Net income for the year ended September 30, 1994, was $3.1
million, an increase of $946,000, or 44.87%, over the results for the year ended
September 30, 1993. Included in the current years earnings were the impact of
changes in accounting principles for the treatment of post-retirement benefits
other than pensions (SFAS No. 106) and for the treatment of income taxes (SFAS
No. 109) which, together, accounted for $233,000 in non-recurring net earnings.
Net income before the impact of these changes in accounting principals was $2.8
million, or 33.83% over the prior years earnings of $2.1 million. The components
of this increase were primarily increases of $1.2 million in net interest
income, discussed below, $281,000 in negative goodwill amortization and
 
                                       48
<PAGE>   52
 
a decrease in the provision for loan losses of $230,000. These increases were
offset by increases in noninterest expenses of $996,000 due primarily to
increases in compensation and benefits.
 
     Interest income:  Interest income increased by $1.8 million to $15.4
million for the fiscal year ended September 30, 1994 compared to the fiscal year
ended September 30, 1993. This increase was mainly due to increases in average
interest-earning assets of $42.1 million (due primarily to the Peru
interest-earning assets acquired in fiscal year 1994) which was partially offset
by the general decline in interest earned on interest-earning assets during the
year. The weighted average yield on interest-earning assets decreased from 7.75%
in fiscal year 1993 to 7.09% in fiscal year 1994. Average loans increased by
$17.0 million during fiscal year 1994 with a reduction in yield from 8.49% in
fiscal year 1993 to 8.18% in fiscal year 1994. Average investment securities
increased by $16.9 million during fiscal year 1994, with a decrease in yield
from 5.39% in fiscal 1993 to 4.69% in fiscal 1994.
 
     Interest Expense:  Total interest expense for the year ended September 30,
1994 was $6.9 million, an increase of $649,000, or 10.38% from the prior year.
This increase resulted primarily from the increase of average deposits of $36.0
million (due mainly to the Peru deposits acquired in fiscal year 1994) which was
partially offset by the general decline in interest rates during fiscal 1994.
The weighted average rate paid on deposits decreased from 4.14% in fiscal year
1993 to 3.69% in fiscal year 1994. (See Note 8 in the footnotes to the financial
statements for a summary of the rates being paid on the various types of deposit
accounts).
 
     Provision for Loan Losses:  The provision for the year ended September 30,
1994 was $455,000 compared to $685,000 in the prior year, a decrease of
$230,000, or 33.53%. Management has decreased the provision as a result of its
analysis of the allowance for loan losses. The provision less net charge-offs
for the year of $10,000 and the addition of the Peru allowances of $190,000
increased the allowance for loan losses to $2.3 million at September 30, 1994,
from $1.7 million at September 30, 1993. The ratio of allowance for loan losses
to non-performing loans decreased from 742.61% at September 30, 1993 to 588.92%
at September 30, 1994. This decrease is due primarily to increases in
non-performing loans in the current year of $167,000 offsetting the increase in
the allowance. The ratio of allowance for loan losses to net total loans
increased from 1.25% at September 30, 1993 to 1.46% at September 30, 1994 due
mainly to the increase in the allowance.
 
     Non interest income:  Noninterest income for fiscal year 1994 was $879,000,
an increase of $288,000, or 48.9%, over fiscal year 1993. This main reason for
this increase was the addition of negative goodwill, as a result of the Peru
transaction, amortization which totaled $281,000 in fiscal year 1994. Gains on
the sale of loans increased by $37,000 which was offset by a write down of the
loans held for sale portfolio of $43,000 on September 30, 1994. Approximately
$15.7 million and $7.0 million of fixed rate loans were sold in fiscal years
1994 and 1993, respectively. Larger amounts were originated and sold in the
current fiscal year due to the historically low interest rate levels and the
consumers perceptions that interest rates had bottomed out during the year. The
continuance of large amounts of refinancings and the corresponding sales is
difficult to predict and will be based upon the levels of interest rates in
conjunction with consumer demands. Also during 1994, a writedown of $43,000 was
made on a security for which management deemed the decline in value to be other
than temporary.
 
     Noninterest Expense:  Total noninterest expense for fiscal year 1994
totaled $4.5 million compared to $3.5 million for the prior year, an increase of
$996,000, or 28.49%. This increase was mainly due to increases in compensation
and benefits of $433,000. This increase in compensation and benefits is due
mainly to the addition of Peru personnel. Other expenses increased by $365,000
which was due mainly to increases in holding company expenses of $201,000.
Increased holding company expenses were mainly related to expenses in
conjunction with work done by outside parties (legal counsel, accounting, and
investment advisors) related to the Merger of CIB by NCC. The majority of the
remaining increase in other expenses can be attributed to normal inflationary
increases and the addition of Peru. Federal deposit insurance premiums increased
by $162,000 due mainly to the increased deposits from the addition of Peru and
the receipt in the year earlier period of $77,000 credit for the final
distribution of the secondary reserve.
 
                                       49
<PAGE>   53
 
     Income Tax Expense:  Income tax expense decreased by $34,000 due mainly to
the amortization of deferred taxes relative to purchase accounting adjustments
established in conjunction with the acquisition of Peru.
 
YEAR ENDED SEPTEMBER 30, 1993 COMPARED TO YEAR ENDED SEPTEMBER 30, 1992
 
     General:  Net income for the year ended September 30, 1993, was $2.1
million, an increase of $144,000, or 7.31%, over the results for the year ended
September 30, 1992. The components of this increase were primarily an $802,000
increase in net interest income discussed below, and a $137,000 increase in
noninterest income due primarily to increases in gains on sales of loans in the
secondary market. These increases were offset by the following items. First, the
provision for loan losses increased by $198,000 based on management's analysis
of the adequacy of the allowance for loan losses. Second, noninterest expenses
increased $369,000 due primarily to increases in compensation and benefits
discussed below. Third, income tax expense has increased by $229,000 due
primarily to increases in income subject to tax.
 
     Interest Income:  Interest income decreased by $1.0 million to $13.6
million for the fiscal year ended September 30, 1993 compared to the fiscal year
ended September 30, 1992. This decrease was due to the general decline in
interest rates; however, the effect of this decline in rates was partially
offset by increases in interest-earning assets, particularly loans. Average
loans outstanding increased by $11.3 million due to the lower interest rate
environment and management's efforts to aggressively originate loans,
particularly in Hamilton County, Indiana. The weighted average yield on
interest-earning assets decreased from 8.57% in fiscal 1992 to 7.75% in fiscal
1993, primarily due to the decrease in yield on loans from 9.38% in fiscal 1992
to 8.49% in fiscal 1993, as well as decreases in yield for all other
interest-earning asset categories.
 
     Interest Expense:  Total interest expense for the year ended September 30,
1993 was $6.3 million, a decrease of $1.8 million, or 22.39% from the prior
year. This decrease resulted primarily from the general decline in interest
rates paid on deposits during the year. There was a shift during the year
between certificates of deposit and passbook savings accounts. Certificates of
deposit decreased $3.2 million in fiscal year 1993 (although $5.7 million in
certificates were received in the last quarter of fiscal 1993 and will mature
and are expected to be withdrawn in the first quarter of fiscal 1994), while
passbook savings increased $9.3 million. Management believes that this shift is
due to the relatively low rate on longer term certificates of deposit and the
customers' perception that interest rates have reached their low. Demand and NOW
account balances increased by $4.5 million due to more aggressive marketing of
these services. The weighted average rates paid on deposits decreased from 5.51%
in fiscal 1992 to 4.14% in fiscal 1993, with all categories experiencing a drop
in average rates.
 
     Provision for Loan Losses:  The provision for the year ended September 30,
1993 was $685,000 compared to $487,000 in the prior year, an increase of
$198,000, or 40.55%. Management has increased the provision due to the large
increases in the loan portfolio, including construction loans and commercial
loans, the current uncertainties in the economy, particularly as they relate to
the major employers in Kokomo's market areas which are tied to the automotive
industry, the current regulatory environment and to provide for any potential
losses on the $1.9 million of loans outstanding at September 30, 1993 to
facilitate the sale of EPIC foreclosed real estate. The provision, less net
charge-offs for the year of $34,000, increased the allowance for loan losses to
$1.7 million at September 30, 1993, from $1.0 million at September 30, 1992.
This increase in the allowance for loan losses resulted in an increase in the
ratio of the allowance for loan losses to total loans from .78% in fiscal year
1992 to 1.25% in fiscal year 1994. The increase in the allowance for loan losses
combined with a reduction in non-performing loans resulted in an increase in the
ratio of the allowance for loan losses to non-performing loans from 90.79% in
fiscal year 1992 to 742.61% in fiscal year 1993.
 
     Noninterest Income:  Noninterest income for the year ended September 30,
1993 totaled $591,000, an increase of $137,000 or 30.12%, over the year ended
September 30, 1992. An increase in the net gain on sale of loans of $100,000
accounted for the majority of this increase. Approximately $7.0 million and $2.3
million of fixed rate loans were sold in fiscal years 1993 and 1992,
respectively.
 
                                       50
<PAGE>   54
 
     Noninterest Expense:  Total noninterest expense for fiscal year 1993
totaled $3.5 million compared to $3.1 million for the prior year, an increase of
$369,000 or 11.80%. This increase was mainly due to increases in compensation
and benefits of $366,000. This increase in compensation and benefits was due
primarily to two factors. First, normal inflationary increases in compensation
and benefits and the addition of personnel have increased compensation by
approximately $214,000. Second, $114,000 was accrued in fiscal 1993 for Kokomo's
contribution to its retirement plan (this accrual was significantly less than
that in the same period in the prior year due to the funding level of the
retirement plan). Additional items contributing to the increase in noninterest
expense included a $22,000 increase in loan expense (due to increased
originations), $21,000 in ATM processing costs (due to the switching of ATM
processors), $18,000 in data processing costs (due to an increased number of
accounts and increased charges), and $15,000 in employment taxes (due to
increased compensation). These increases were partially offset by decreases in
federal deposit insurance premiums of $49,000 (due to receipt of a $77,000
credit for the final distribution of the secondary reserve), and by decreases in
professional fees of $34,000.
 
     Income Tax Expense:  Income tax expense increased by $229,000 for the year
ended September 30, 1993, compared to the prior year. This increase was due
mainly to increased pretax income.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The standard measure of liquidity for savings associations is the ratio of
cash and eligible investments to a certain percentage of net withdrawable
savings and borrowings due within one year. The minimum required ratio is
currently set by OTS regulation at 5%, of which 1% must be comprised of
short-term investments (i.e., generally with a term of less than one year). At
September 30, 1994, Kokomo's liquidity ratio was 29.60% and the short-term
liquidity ratio was 29.41%. At September 30, 1994, the total of Kokomo's cash
and eligible investments were $56.3 million, of which $55.9 million were
comprised of short-term assets. Therefore, Kokomo's liquidity is well above the
regulatory requirement.
 
     Periodically, Kokomo obtains large public fund deposits, which can cause
significant fluctuations in Kokomo's deposit base and alter the liquidity ratio.
These public funds are generally short-term deposits which Kokomo matches with
specific assets of similar maturity. Such matching allows Kokomo sufficient
liquidity when the deposits mature.
 
     CIB's liquidity, represented by cash and cash equivalents, is a result of
its operating, investing, and financing activities. These activities are
discussed below for the years ended September 30, 1994, 1993 and 1992.
 
     Year Ended September 30, 1994.  During the year ended September 30, 1994,
there was a net increase of $6.3 million in cash and cash equivalents. The major
source of this cash was the decrease in interest-earning time deposits with
other financial institutions of $14.4 million. Other sources of cash during the
year included principal collected on mortgage-backed securities of $7.3 million,
net income of $3.1 million, cash balances acquired in merger conversion with
Peru in the amount of $5.2 million and maturities of investment securities of
$28.3 million. The major use of cash during the year, which partially offset
these sources of cash, include purchases of investment and mortgage-backed
securities of $63.8 million.
 
     Year Ended September 30, 1993.  During the year ended September 30, 1993,
there was a net increase of $6.9 million in cash and cash equivalents. The major
source of this cash was the increase in deposits of $10.0 million. Other sources
of cash during the year included principal collected on mortgage-backed
securities of $4.0 million, net income of $2.1 million, and maturities of
investment securities of $2.0 million. The major use of cash during the year,
which partially offset these sources of cash, included a net increase in loans
of $4.5 million, net change in loans held for sale of $3.2 million, and
purchases of investment and mortgage-backed securities of $3.2 million.
 
     Year Ended September 30, 1992.  During the year ended September 30, 1993,
there was a net decrease of $6.8 million in cash and cash equivalents. The major
use of this decrease in cash was an increase in loans of $14.2 million. Other
uses of cash during the year included purchases of mortgage-backed and
investment securities of $9.0 million and a net increase in interest-earning
time deposits of $4.4 million. The major sources of cash during the year, which
partially offset these uses of cash, include maturities of investment securities
and principal repayments on mortgage-backed securities totaling $11.5 million
and increases in deposits of $5.6

million. Operating activity also provided net cash of $3.2 million which was
primarily net income of $2.0 million.
 
     Borrowings may be used to compensate for reductions in other sources of
funds such as deposits and to assist in asset/liability management. CIB has
historically not borrowed significant amounts and any borrowings have been short
term. There were no borrowings as of September 30, 1994. Also, CIB had
commitments to fund loan originations, unused lines of credit and letters of
credit with borrowers of $26.6 million at September 30, 1994. In the opinion of
management, CIB has sufficient cash flow and borrowing capacity to meet current
and anticipated funding commitments.
 
     Under currently effective capital regulations, savings associations must
meet a 1.5% tangible capital requirement, a 3% leverage ratio (or core capital)
requirement and a total risk-based capital to risk-weighted assets ratio of
8.0%. At September 30, 1994, Kokomo's tangible capital ratio was 13.31%, its
leverage ratio was 13.31% and its risk-based capital to risk-weighted assets
ratio was 24.85%. Therefore, Kokomo's capital significantly exceeds all of the
capital requirements currently in effect.
 
IMPACT OF INFLATION
 
     The audited consolidated financial statements presented herein have been
prepared in accordance with generally accepted accounting principles. These
principles require the measurement of financial position and operating results
in terms of historical dollars, without considering changes in the relative
purchasing power of money over time due to inflation.
 
     The primary assets and liabilities of CIB are monetary in nature. As a
result, interest rates have a more significant impact on CIB's performance than
the effects of general levels of inflation. Interest rates, however, do not
necessarily move in the same direction or with the same magnitude as the price
of goods and services, since such prices are affected by inflation. In a period
of rapidly rising interest rates, the liquidity and maturity structures of CIB's
assets and liabilities are critical to the maintenance of acceptable performance
levels. For a discussion of CIB's efforts to restructure its assets and to
reduce its vulnerability to changes in interests rates, see "-- Asset/Liability
Management."
 
     The principal effect of inflation, as distinct from levels of interest
rates, on earnings is in the area of other expense. Such expense items as
employee compensation, employee benefits, and occupancy and equipment costs may
be subject to increases as a result of inflation. An additional effect of
inflation is the possible increase in the dollar value of the collateral
securing loans made by CIB. Management is unable to determine the extent, if
any, to which properties securing CIB's loans have appreciated in dollar value
due to inflation.
 
CURRENT ACCOUNTING ISSUES
 
     In May 1993, FASB issued Statement of Financial Accounting Standards No.
114 "Accounting by Creditors for Impairment of a Loan"("SFAS 114"). SFAS 114
specifies that allowances for loan losses on impaired loans should be determined
using the present value of estimated future cash flows of the loan, discounted
at the loan's effective interest rate. A loan is impaired when it is probable
that all principal and interest amounts will not be collected according to the
loan contract. SFAS 114 is effective for fiscal years beginning after December
15, 1994. Management has not yet determined the impact of adoption of SFAS 114
on the financial position or results of operations of CIB.
 
     In May 1993, FASB issued Statement of Financial Accounting Standards No.
115 "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS
115"). SFAS 115 focuses on the accounting and reporting treatment of investment
securities. SFAS 115 expands the use of fair value accounting for investment
securities classified as available for sale, with unrealized gains and losses
reported as a separate component of stockholders' equity. Securities classified
as held to maturity will be those CIB has the positive intent and ability to
hold to maturity, accounted for at amortized cost. Trading securities include
those purchased and held principally to sell in the near term and are accounted
for at fair value with unrealized gains and losses included in current earnings.
SFAS 115 is effective for fiscal years beginning after December 15, 1993. The
impact of adoption of SFAS 115 on the financial position or results of
operations of CIB will not be material.

                       CERTAIN REGULATORY CONSIDERATIONS
 
GENERAL
 
     Bank holding companies, banks, savings and loan holding companies and
savings and loans are extensively regulated under both federal and state law. To
the extent that the following information describes statutory and regulatory
provisions, it is qualified in its entirety by reference to the particular
statutory and regulatory provisions. A change in applicable law or regulation
may have a material effect on the business of NCC or CIB.
 
     As a bank holding company, NCC is subject to regulation under the BHCA and
its examination and reporting requirements. Under the BHCA, bank holding
companies may not (subject to certain limited exceptions) directly or indirectly
acquire the ownership or control of more than 5% of any class of voting shares
or substantially all of the assets of any company, including a bank, without the
prior written approval of the FRB. In addition, bank holding companies are
generally prohibited under the BHCA from engaging in nonbanking activities,
subject to certain exceptions.
 
     The BHCA prohibits the FRB from approving the acquisition by a bank holding
company of more than 5% of any class of the voting shares of, or substantially
all the assets of, any bank (or its holding company) located outside of the
state in which the operations of such acquiring bank holding company's banking
subsidiaries are principally conducted on the date such company became a bank
holding company, unless such acquisition is specifically authorized by the laws
of the state in which the bank to be acquired is located. Many states, including
Indiana, Ohio and Kentucky, have adopted legislation that permits out-of-state
bank holding companies located throughout the United States to acquire local
banks and bank holding companies.
 
     As a registered non-diversified savings and loan holding company, CIB is
subject to regulation, examination and supervision by the OTS and to OTS
reporting requirements. As a federally chartered savings bank, Kokomo is also
subject to such regulation, examination, supervision and reporting requirements.
Kokomo's deposits are insured by SAIF, and accordingly, the institution is also
subject to examination by and the regulations of the FDIC. Like NCC, CIB is
affected significantly by the actions of the FRB as it attempts to control the
money supply and credit availability.
 
     CIB is required to obtain the prior approval of the OTS before acquiring
control of, or more than 5% of the voting shares of, any other savings
association or savings association holding company. Because it is, at present, a
unitary savings and loan holding company (i.e., owns only one savings
association subsidiary), and because its savings association meets the qualified
thrift lender test (requiring that a specified percentage of Kokomo's assets be
housing-related), CIB is generally free of restrictions on its permissible
business activities, except for restrictions that could be imposed for specific
safety and soundness reasons. If CIB were to acquire another savings association
and thereby become a multiple savings and loan holding company, it would become
subject, with limited exceptions, to the same limitations on its permissible
business activities as are applicable to bank holding companies, such as NCC,
and would have to obtain prior OTS approval before engaging in other activities
permissible for bank holding companies. Any non-supervisory acquisition in a
state other than Indiana that resulted in CIB's becoming a multiple savings and
loan holding company, and any subsequent non-supervisory transaction that
resulted in the acquisition of additional savings associations outside Indiana
by CIB, could only be approved by the OTS if the state where the institution to
be acquired is located allows, by specific statutory language, its savings
associations to be acquired by an Indiana savings association or savings
association holding company.
 
     Kokomo is a member of the Federal Home Loan Bank ("FHLB") System, which
consists of twelve regional banks. The Federal Housing Finance Board, an
independent agency, controls the FHLB System, including the Federal Home Loan
Bank of Indianapolis ("FHLB of Indianapolis"). The FHLB System provides a
central credit facility primarily for member savings and loan associations,
savings banks, and other member financial institutions. Kokomo is required to
hold shares of capital stock in the FHLB of Indianapolis in an amount at least
equal to the greater of 1% of the aggregate principal amount of its unpaid
residential mortgage loans, home purchase contracts, and similar obligations at
the end of each calendar year; .3% of its assets; or 1/20 (or such greater
fraction established by the FHLB) of outstanding FHLB advances, commitments,
lines of credit and letters of credit. Kokomo is currently in compliance with
this requirement.

PAYMENT OF DIVIDENDS
 
     Each of NCC and CIB is a legal entity separate and distinct from its
banking, savings bank, and other subsidiaries. Most of NCC's and CIB's revenues
result from dividends paid to it by its bank or savings bank subsidiaries, as
applicable. There are statutory and regulatory requirements applicable to the
payment of dividends by subsidiary banks as well as by NCC to its stockholders
and CIB to its shareholders.
 
     Each state bank subsidiary that is a member of the Federal Reserve System
and each national banking association is required by federal law to obtain the
prior approval of the FRB or the Comptroller of the Currency (the
"Comptroller"), as the case may be, for the declaration and payment of dividends
if the total of all dividends declared by the board of directors of such bank in
any year will exceed the total of (a) such bank's net profits (as defined and
interpreted by regulation) for that year plus (b) the retained net profits (as
defined and interpreted by regulation) for the preceding two years, less any
required transfers to surplus. In addition, these banks may only pay dividends
to the extent that retained net profits (including the portion transferred to
surplus) exceed bad debts (as defined by regulation).
 
     As of September 30, 1994, NCC's subsidiary banks, without obtaining
governmental approvals, could declare aggregate dividends of approximately
$194.3 million.
 
     The payment of dividends by NCC and its bank subsidiaries are also affected
by various regulatory requirements and policies, such as the requirements to
maintain adequate capital. In addition, if, in the opinion of the applicable
regulatory authority, a bank under its jurisdiction is engaged in or is about to
engage in an unsafe or unsound practice (which, depending on the financial
condition of the bank, could include the payment of dividends), such authority
may require, after notice and hearing, that such bank cease and desist from such
practice. The FRB and the Comptroller have each indicated that paying dividends
that deplete a bank's capital base to an inadequate level would be an unsafe and
unsound banking practice. The FRB, the Comptroller and the Federal Deposit
Insurance Corporation (the "FDIC") have issued policy statements which provide
that bank holding companies and insured banks should generally only pay
dividends out of current operating earnings.
 
     There are also statutory limits on the amount of dividends Kokomo can pay
to the CIB without regulatory approval. Under OTS regulations, a converted
savings association may not declare or pay a cash dividend if such payment would
reduce its net worth below the amount required for the liquidation account
created at the time the association was converted. In addition, OTS regulations
establish a three-tier system of regulation which imposes limitations on the
extent to which a savings association may make "capital distributions." A
savings association which has total capital (immediately prior to and after
giving effect to the capital distribution) that is at least equal to its fully
phased-in capital requirements is classified as a tier one institution. Kokomo
is now, and expects to continue to be, a tier one institution and, therefore,
would be able to pay cash dividends to CIB, after prior notice but without the
approval of the OTS, up to 100% of its net income to date during the calendar
year, plus an amount that would reduce by one-half its "surplus capital ratio"
(the excess over its fully phased-in capital requirements) at the beginning of
the calendar year. Any additional amount of capital distributions would require
prior regulatory approval. Under these provisions, CIB could, without regulatory
approval, declare dividends of approximately $11.7 million at September 30,
1994.
 
CERTAIN TRANSACTIONS BY BANK HOLDING COMPANIES WITH THEIR AFFILIATES
 
     There are also various legal restrictions on the extent to which NCC, CIB
and most of their respective nondepository subsidiaries can borrow or otherwise
obtain credit from, or engage in certain other transactions ("covered
transactions") with, depository institution subsidiaries. Such borrowings and
other transactions by an insured depository institution with nondepository
affiliates are limited to the following amounts: (a) in the case of any one such
affiliate, the aggregate amount of covered transactions of the insured
depository institution and its subsidiaries cannot exceed 10% of the capital
stock and surplus of the insured depository institution; and (b) in the case of
all affiliates, the aggregate amount of covered transactions of the insured
depository institution and its subsidiaries cannot exceed 20% of the capital
stock and surplus of the insured depository institution. In addition, such
extensions of credit must be collateralized in prescribed amounts. Furthermore,
a bank holding company, a savings and loan holding company and its subsidiaries
are prohibited from engaging in certain tie-in arrangements in connection with
any extension of credit, lease or sale of property or furnishing of services.
 
                                       54

FDIC INSURANCE
 
     The FDIC has the authority to raise the insurance premiums for institutions
in BIF and SAIF to a level necessary to achieve a target reserve level of 1.25%
of insured deposits within not more than 15 years. In addition, the FDIC has the
authority to impose special assessments in certain circumstances. The level of
deposit premiums affects the profitability of subsidiary banks and thrifts and
thus the potential flow of dividends to parent companies. See "Certain
Regulatory Considerations -- Payment of Dividends."
 
     Under a transitional risk-based insurance assessment system that became
effective January 1, 1993, and other relevant information (such as supervisory
evaluations), the assessment rates under the new system range from 0.23%, to
0.31%, depending upon the assessment category into which the insured institution
is placed.
 
     On June 17, 1993, the FDIC adopted a permanent risk-based assessment system
for assessment periods beginning on and after January 1, 1994. The permanent
system retains the transitional system without substantial modification.
 
     The current SAIF insurance premium assessment schedule applicable to
savings associations like Kokomo could rise to pay for the resolution of
troubled institutions. Moreover, since the reserve ratio of BIF is currently
higher than that of SAIF, it is anticipated that BIF premiums may start
declining in the next year or so. Such events could cause a disparity between
the assessment rates of SAIF and BIF members.
 
CAPITAL
 
     The FRB has adopted risk-based capital guidelines for bank holding
companies. The guidelines became fully phased in at the end of 1992. The minimum
guideline for the ratio of total capital ("Total Capital") to risk-weighted
assets (including certain off-balance-sheet items, such as standby letters of
credit) is 8%. To be considered well-capitalized, Total Capital must be at least
10%. At least half of minimum required Total Capital of 8% is to be composed of
common shareholders' equity, minority interests in the equity accounts of
consolidated subsidiaries and a limited amount of perpetual preferred stock,
less goodwill and certain other intangibles ("Tier 1 Capital"). To be considered
well-capitalized, Tier 1 Capital must be at least 6%. The remainder may consist
of subordinated debt, other preferred stock and a limited amount of loan and
lease loss allowance.
 
     The following tables set forth the Tier 1 Capital to risk-weighted assets
ratios and the Total Capital to risk-weighted assets ratios for NCC and CIB
individually and on a pro forma combined basis as of June 30, 1994.
 
                  TIER 1 CAPITAL TO RISK-WEIGHTED ASSETS RATIO

                          12.97%     24.85%      13.03%
</TABLE>
 
     In addition, the FRB has established minimum leverage ratio guidelines for
bank holding companies. The guidelines provide for a minimum ratio of Tier 1
Capital to average total assets (excluding the loan and lease loss allowance,
goodwill and certain other intangibles) ( the "Leverage Ratio") of 3% for bank
holding companies that meet specified criteria, including having the highest
regulatory rating. To be considered well-capitalized, the
 
                                       55
<PAGE>   59
 
Leverage Ratio must be 5% or more. NCC's Leverage Ratio at June 30, 1994 was
7.98%. At June 30, 1994, on a pro forma combined basis, NCC's Leverage Ratio
would be 8.01%. The guidelines further provide that bank holding companies
making acquisitions will be expected to maintain strong capital positions
substantially above the minimum supervisory levels.
 
     Savings and loan holding companies, such as CIB, are not subject to such
capital guidelines, but Kokomo is subject to substantially similar capital
requirements adopted by the OTS. At September 30, 1994, Kokomo's tangible
capital ratio, core capital ratio, and total risk-based capital ratios were
13.31%, 13.31%, and 21.85%, respectively. Thus, Kokomo had capital well in
excess of all applicable requirements.
 
     Each of NCC's subsidiary banks is subject to similar capital requirements
adopted by the FRB, the Comptroller or the FDIC, as the case may be. At June 30,
1994, each of NCC's subsidiary banks had a Tier 1 Capital ratio and a Total
Capital ratio (computed under the current guidelines) in excess of 6% and 10%,
respectively. All of NCC's subsidiary banks are well-capitalized under the
current capital guidelines.
 
     In the fourth quarter of 1992, the federal banking agencies adopted
regulations with respect to risk-based and leverage capital ratios that require
all intangibles, other than limited amounts of purchased mortgage servicing
rights and purchased credit card relationships, to be deducted from Tier 1
Capital. Federal banking agencies have recently adopted other modifications
related to risk-based and leverage capital ratios, and have proposed an
additional capital requirement tied to a bank's interest-rate risk. NCC and CIB
do not expect the aggregate impact on these regulatory changes to have a
significant impact on their capital position.
 
     Failure to meet capital guidelines could subject an insured bank to a
variety of enforcement remedies, including the possible termination of deposit
insurance by the FDIC and a prohibition on the taking of brokered deposits. See
"FDICIA" below.
 
     Bank regulators continue to indicate their desire to raise capital
requirements applicable to banking organizations beyond their current levels.
However, the managements of NCC and CIB are unable to predict whether and when
higher capital requirements might be imposed and, if they are imposed, at what
levels and on what schedule.
 
HOLDING COMPANY SUPPORT OF SUBSIDIARY BANKS AND SAVINGS BANKS
 
     Under FRB policy, NCC is expected to act as a source of financial strength
to each of its subsidiary banks and to commit resources to support each of such
subsidiaries. This support may be required at times when, absent such FRB
policy, NCC would not otherwise be required to provide it. In addition, any
capital loans by NCC or CIB to a subsidiary bank or savings association would be
subordinate in right of payment to deposits and to certain other indebtedness of
such bank. In the event of a bank holding company's or savings and loan holding
company's bankruptcy, any commitment by the bank holding company or by the
savings and loan holding company to a federal bank regulatory agency to maintain
the capital of a subsidiary bank or savings association will be assumed by the
bankruptcy trustee and entitled to a priority of payment. This priority would
apply to guarantees of capital restoration plans under the Federal Deposit
Insurance Corporation Improvement Act of 1991. See "FDICIA" below.
 
     Under FIRREA, a depository institution insured by the FDIC can be held
liable for any loss incurred by, or reasonably expected to be incurred by, the
FDIC in connection with (i) the default of a commonly controlled FDIC-insured
depository institution, or (ii) any assistance provided by the FDIC to any
commonly controlled FDIC-insured depository institution in danger of default.
The validity of this provision is currently the subject of judicial proceedings.
 
FDICIA
 
     On December 19, 1991, a major banking bill entitled the Federal Deposit
Insurance Corporation Improvement Act of 1991 ("FDICIA") was enacted. FDICIA
substantially revises the bank regulatory and funding provisions of the Federal
Deposit Insurance Act and makes revisions to several other federal banking
statutes.
 
                                       56
<PAGE>   60
 
     Among other things, FDICIA requires the federal banking regulators to take
"prompt corrective action" in respect of depository institutions that do not
meet minimum capital requirements. The depository institution subsidiaries of
NCC and CIB have capital levels above the minimum requirements. See "CERTAIN
REGULATORY CONSIDERATIONS -- Capital" above. In addition, an institution that is
not well capitalized is generally prohibited from accepting brokered deposits
and offering interest rates on deposits higher than the prevailing rate in its
market; also, "pass through" insurance coverage may not be available for certain
employee benefit accounts. FDICIA also requires the holding company of any
undercapitalized depository institution to guarantee, in part, certain aspects
of such depository institution's capital plan for such plan to be acceptable.
NCC's and CIB's subsidiary depository institutions qualify as "well
capitalized."
 
     FDICIA contains numerous other provisions, including accounting, audit and
reporting requirements, termination of the "too big to fail" doctrine beginning
in 1995 (except in special cases), limitations on the FDIC's payment of deposits
at foreign branches, new regulatory standards in such areas as asset quality,
earnings and compensation and revised regulatory standards for, among other
things, power of state banks, real estate lending and capital adequacy.
 
     FDICIA also requires that a depository institution provide 90 days prior
notice of the closing of any branches.
 
RECENT AND PROPOSED LEGISLATION
 
     The Riegle Community Development and Regulatory Improvement Act of 1994 was
recently signed into law. It includes new laws on high cost and reverse
mortgages, bank regulatory relief, community development banking, money
laundering and national flood insurance.
 
     The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
also recently was enacted. It permits bank holding companies to acquire banks in
other states and, with state consent and subject to certain limitations, allows
banks to acquire out-of-state branches either through merger or de novo
expansion.
 
     In addition, Congress is considering legislation that would consolidated
the federal supervision and regulation of all U.S. financial institutions into
one administrative body. It cannot be predicted with certainty whether or when
any such legislation may be enacted or the extent to which any such legislation
would affect the banking industry.
 
                        DESCRIPTION OF NCC CAPITAL STOCK
 
COMMON STOCK
 
     General.  NCC has 350,000,000 authorized shares of NCC Common, of which
150,148,676 shares were issued and outstanding on September 30, 1994, and an
additional 7,949,550 shares were reserved for issuance in connection with NCC's
Stock Option Plans (options to purchase 8,302,639 shares of NCC Common have been
granted and are outstanding) and Restricted Stock Plan (329,050 shares of NCC
Common have been awarded and are outstanding). The shares of NCC Common to be
issued in connection with the Merger will be validly issued, fully paid and
nonassessable. NCC Common is listed on the NYSE (Symbol: NCC). The transfer
agent, registrar and dividend disbursing agent for shares of NCC Common is
National City Bank, Cleveland.
 
     Dividend and Liquidation Rights.  Holders of NCC Common are entitled to
such dividends as may be declared by NCC's Board of Directors out of funds
legally available therefor. In the event of liquidation, holders of NCC Common
will be entitled to receive pro rata any assets distributable to stockholders in
respect of the number of shares held by them. The dividend and liquidation
rights of NCC Common are subject to the rights of any preferred stock of NCC.
 
     Voting, Preemptive, Conversion and Redemption Rights.  Holders of NCC
Common are entitled to one vote per share on all matters submitted to
stockholders and are not entitled to cumulative voting rights in the election of
directors or to preemptive rights for the purchase of additional shares of any
class of NCC's stock. NCC Common has no conversion or redemption rights.

<PAGE>   61
 
PREFERRED STOCK
 
     General.  Under NCC's Certificate of Incorporation (the "NCC certificate"),
the Board of Directors of NCC is authorized without further stockholder action
to provide for the issuance of up to 5,000,000 shares of preferred stock,
without par value, in one or more series as the Board of Directors may
determine, and to fix the relative powers, preferences and rights (including
voting rights) of each such series of preferred stock in relation to the powers,
preferences and rights of any other series of preferred stock. Voting rights, if
any, may be general, special, conditional or limited. The Board of Directors of
NCC also has the discretion to determine the number of votes per share which
each holder of a share of a series of the preferred stock will have, but in no
event may any holder of any series of NCC preferred stock be entitled to more
than one vote per share. Additionally, the Board of Directors of NCC is
authorized to permit the holders of a series of preferred stock to vote
separately or together with the holders of one or more other series of preferred
stock on all or some matters as a separate voting group. NCC may, at its option,
elect to offer depositary shares evidenced by depositary receipts, each
representing a fractional interest in a share of the particular series of the
NCC preferred stock issued and deposited with a depositary selected by NCC.
 
     Convertible Preferred Stock.  By resolution dated April 11, 1991, the Board
of Directors of NCC designated a series of NCC preferred stock as 8% Cumulative
Convertible Preferred Stock, without par value, of NCC ("Convertible Preferred
Stock"). The number of shares constituting such series is 800,000, of which
757,160 shares (3,785,800 depositary shares) were issued and outstanding as of
September 30, 1994. Each depositary share of Convertible Preferred Stock (a
"Depositary Share") represents a one-fifth interest in a share of Convertible
Preferred Stock. The Depositary Shares are listed on the NYSE. The transfer
agent, registrar, dividend disbursing agent, redemption agent and depositary for
shares of Convertible Preferred Stock and Depositary Shares is National City
Bank, Cleveland.
 
     Dividends.  Holders of shares of Convertible Preferred Stock are entitled
to receive, when and as declared by the Board of Directors of NCC out of funds
legally available therefor, cash dividends at the rate of 8% per annum
(equivalent to $4.00 per Depositary Share). Dividends on Convertible Preferred
Stock are payable quarterly on February 1, May 1, August 1 and November 1 of
each year, commencing August 1, 1991, at such annual rate. Dividends are
cumulative from the date of original issue.
 
     Redemption.  Shares of Convertible Preferred Stock will not be redeemable
prior to May 1, 1996. The shares of Convertible Preferred Stock will be
redeemable at the option of NCC, in whole or in part, at any time or from time
to time, on or after May 1, 1996, on not less than 30 nor more than 60 days
notice by mail, at a redemption price of $260 per share (equivalent to $52.00
per Depositary Share) during the period from May 1, 1996 to but not including
May 1, 1997, and thereafter at the redemption prices set forth below during the
12-month periods beginning on May 1, of the years shown below, plus in each case
accrued and unpaid dividends to the redemption date.

</TABLE>
 
     Convertible Preferred Stock will not be subject to any sinking fund or
other obligation of NCC to redeem or retire Convertible Preferred Stock.
 
     Liquidation Rights.  In the event of any voluntary or involuntary
liquidation, dissolution or winding up of NCC, the holders of shares of
Convertible Preferred Stock are entitled to receive out of assets of NCC
available for distribution to stockholders, before any distribution of assets is
made to holders of NCC Common or of any other shares of stock of NCC ranking as
to such a distribution junior to the shares of Convertible Preferred Stock,
liquidating distributions in the amount of $250 per share (equivalent to $50 per
Depositary Share) plus accrued
 
                                       58
<PAGE>   62
 
and unpaid dividends. After payment of such liquidating distributions, the
holders of shares of Convertible Preferred Stock will not be entitled to any
further participation in any distribution of assets by NCC.
 
     Voting Rights.  Except as indicated below, or except as expressly required
under the DGCL, the holders of Convertible Preferred Stock will have no voting
rights.
 
     If the equivalent of six quarterly dividends payable on Convertible
Preferred Stock is in arrears, the number of directors of NCC will be increased
by two, and the holders of Convertible Preferred Stock, voting separately as a
class with the holders of shares of any one or more other series of preferred
stock of NCC ranking on a parity with Convertible Preferred Stock, whether as to
payment of dividends or the distribution of assets and upon which like voting
rights have been conferred and are exercisable, will be entitled to elect two
directors to fill such vacancies. Such right to elect two additional directors
shall continue until all dividends in arrears have been paid or declared and set
apart for payment. Each director elected by the holders of shares of Convertible
Preferred Stock and all other classes of preferred stock of NCC whose holders
are so entitled to vote shall continue to serve as such director for the full
term for which he shall have been elected, notwithstanding that prior to the end
of such term such default shall cease to exist.
 
     Unless the vote or consent of the holders of a greater number of shares
shall then be required under the DGCL, the affirmative vote or consent of the
holders of at least 66 2/3% of the outstanding shares of Convertible Preferred
Stock and any one or more other series of preferred stock of NCC similarly
affected, voting separately as a single class, without regard to series, will be
required for any amendment, alteration or repeal of NCC's Certificate (or any
certificate amendatory thereof or supplemental thereto providing for the capital
stock of NCC, including any Certificate of Designation or similar document
relating to such series) which would adversely affect the preferences, rights,
powers or privileges of Convertible Preferred Stock and any such other series of
NCC's preferred stock. Unless the vote or consent of the holders of a greater
number of shares shall then be required by law, the affirmative vote or consent
of the holders of at least 66 2/3% of the outstanding shares of Convertible
Preferred Stock and any other series of preferred stock of NCC ranking on a
parity with Convertible Preferred Stock either as to dividends or upon
distribution of assets, voting as a single class, without regard to series, will
be required to create, authorize or issue, or reclassify any authorized stock of
NCC into, or create, authorize or issue any obligation or security convertible
into or evidencing a right to purchase, any shares of any class of stock of NCC
ranking prior to Convertible Preferred Stock and any other series of preferred
stock of NCC ranking on a parity with Convertible Preferred Stock as to
dividends or upon distribution of assets. Subject to the foregoing, NCC's
Certificate may be amended to increase the number of authorized shares of
preferred stock of NCC without the vote of the holders of the outstanding
preferred stock of NCC, including the Convertible Preferred Stock.
 
     Under interpretations adopted by the FRB, if the holders of shares of any
series of preferred stock of NCC (including, in this case, Convertible Preferred
Stock) become entitled to vote for the election of directors because dividends
on such series are in arrears, such series may then be deemed a "class of voting
securities" and a holder of 25% or more of such series (or a holder of 5% or
more if it otherwise exercises a "controlling influence" over NCC) may then be
subject to regulation as a bank holding company in accordance with the BHCA. In
addition, at such time as such series is deemed a class of voting securities,
(a) any other bank holding company may be required to obtain the approval of the
FRB under the BHCA to acquire or retain 5% or more of such series and (b) any
person other than a bank holding company may be required to obtain the approval
of the FRB under the Change in Bank Control Act to acquire or retain 10% or more
of such series.
 
     Conversion Rights.  Shares of Convertible Preferred Stock are convertible
at any time at the option of the holder thereof into shares of NCC Common at a
conversion price of $20.975 per share of NCC Common (equivalent to a conversion
rate of approximately 2.384 NCC Common shares for each Depositary Share),
subject to adjustment as described below (except that a share of Convertible
Preferred Stock or a Depositary Share which has been called for redemption will
be convertible up to and including but not after the close of business on the
tenth day preceding the date fixed for redemption thereof). For purposes of such
conversion, each share of Convertible Preferred Stock will be valued at $250
(equivalent to $50 for each Depositary Share).
 
     In the case of any consolidation or merger to which NCC is a party (other
than a merger or consolidation in which NCC is the continuing corporation), or
in case of any sale or conveyance to another corporation of the
 
                                       59
<PAGE>   63
 
property of NCC as an entirety or substantially as an entirety, or in case of
any statutory exchange of securities with another corporation, there will be no
adjustment of the conversion price but the holder of each share of Convertible
Preferred Stock then outstanding will have the right thereafter to convert such
share into the kind and amount of securities, cash or other property which such
holder would have owned or have been entitled to receive immediately after such
consolidation, merger, statutory exchange, sale or conveyance had such share
been converted immediately prior to the effective date of such consolidation,
merger, statutory exchange, sale or conveyance.
 
     The conversion price is subject to adjustment upon certain events,
including the issuance of NCC Common as a dividend or distribution on shares of
NCC Common; subdivisions, combinations or reclassifications of NCC Common; the
issuance to holders of NCC Common generally of rights or warrants to subscribe
for NCC Common at less than the then current market price; or the distribution
to the holders of NCC Common generally of evidences of indebtedness, assets
(excluding dividends in cash out of retained earnings) or rights or warrants to
subscribe for securities of NCC other than those mentioned above.
 
     Fractional shares of NCC Common will not be delivered upon conversion, but
a cash adjustment will be paid in respect of such fractional interests, based on
the then current market price of NCC Common.
 
                        DESCRIPTION OF CIB CAPITAL STOCK
 
     General.  CIB is authorized to issue 5,000,000 shares of CIB Common,
without par value, all of which have identical rights and preferences, and
2,000,000 shares of Preferred Stock, without par value. As of November   , 1994,
          shares of CIB Common and no shares of Preferred Stock were issued and
outstanding and           shares of CIB Common were reserved for issuance
pursuant to options outstanding under CIB's Option Plans. The CIB Common is
listed on the NASDAQ under the symbol "KOKO." As of November 14, 1994, CIB had
  shareholders of record. The transfer agent registrar and dividend disbursing
agent for shares of CIB Common is Bank One Indianapolis, NA.
 
     Dividend and Liquidation Rights.  Holders of CIB Common are entitled to
such dividends as may be declared by CIB's Board of Directors out of funds
legally available therefor. In the event of the liquidation or dissolution of
CIB, the holders of the CIB Common will be entitled to receive -- after payment
or provision for payment of all debts and liabilities of CIB -- all assets of
CIB available for distribution, in cash or in kind.
 
     Voting, Preemptive, Conversion and Redemption Rights.  Each holder of CIB
Common is entitled to one vote for each share held on all matters voted upon by
shareholders, subject to the limitations contained in Article 11 of CIB's
Articles of Incorporation. See "Proposed Amendment to the Articles of
Incorporation of CIB." There are no cumulative voting rights for the election of
directors.
 
     Shareholders of CIB have no preemptive rights to acquire additional shares
of CIB Common which may be subsequently issued. The CIB Common has no conversion
or redemption rights.
 
     Preferred Stock.  The Board of Directors of CIB is authorized to issue
preferred stock in series and to fix and state the voting powers, designations,
preferences and relative, participating, optional or other special rights of the
shares of each such series and the qualifications, limitations and restrictions
thereof. Preferred stock may rank prior to the CIB Common as to dividend rights,
liquidation preferences, or both, and may have full or limited voting rights.
The holders of preferred stock will be entitled to vote as a separate class or
series under certain circumstances, regardless of any other voting rights which
such holders may have.

                GENERAL COMPARISON OF NCC AND CIB CAPITAL STOCK
 
GENERAL
 
     If the shareholders of CIB approve the Merger Agreement, and the Merger is
subsequently consummated, all shareholders of CIB will become stockholders of
NCC. NCC is a corporation organized under, and governed by, the DGCL, whereas
CIB is a corporation organized under, and governed by, the IBCL.
 
     The following is a brief summary of certain differences between the
Delaware corporate laws applicable to NCC and the Indiana corporate laws
applicable to CIB and certain differences between NCC's Certificate and By-Laws
and CIB's Articles and By-Laws. The purpose of this summary is to briefly
indicate the differences between holding NCC capital stock and CIB capital stock
to the extent such differences are created by the state corporation laws
applicable to NCC and CIB or arise because of differences between NCC's
Certificate and By-Laws and CIB's Articles and By-Laws. THIS SUMMARY IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE DGCL, THE IBCL, NCC'S CERTIFICATE
AND BY-LAWS AND CIB'S ARTICLES AND BY-LAWS.
 
DIRECTORS
 
     NCC's By-Laws provide that the number of directors of NCC shall be
determined by resolution of the Board of Directors, that such directors shall be
elected at the annual meeting of the stockholders of NCC, and that each director
elected shall hold office until his or her successor is duly elected and shall
qualify. The number of directors is currently set at 18. Section 141 of the DGCL
provides that any director or the entire board of directors may be removed, with
or without cause, by the holders of a majority of shares then entitled to vote
at an election of directors. The DGCL provides that, unless the governing
documents of a corporation provide otherwise, vacancies and newly created
directorships resulting from a resignation or any increase in the authorized
number of directors elected by all of the stockholders having the right to vote
as a single class may be filled by a majority of the directors (or sole
director, if applicable) then in office. The NCC Certificate provides that newly
created directorships resulting from any increase in the number of directors and
any vacancy in the Board of Directors resulting from death, resignation,
retirement, disqualification, removal from office or any other cause shall be
filled by the Board of Directors. CIB's Articles provide that the size of the
Board shall range between 5 and 15 directors, with the exact number to be fixed
by resolution adopted by a majority of the total number of CIB directors. The
CIB Board is divided into three classes, with directors in each class elected
for three-year staggered terms. Directors may be removed only for cause and only
by the affirmative vote of 80% of the shares eligible to vote for directors.
Removal for "cause" is limited to the grounds for termination in the OTS
regulation relating to employment contracts of federally-insured savings
associations.
 
     CIB's Articles of Incorporation provide that any vacancy occurring in the
Board of Directors, including a vacancy created by an increase in the number of
directors, shall be filled for the remainder of the unexpired term only by a
majority vote of the directors then in office.
 
LIMITATION OF DIRECTOR LIABILITY IN CERTAIN CIRCUMSTANCES
 
     As permitted by the DGCL, Article Seventh of NCC's Certificate provides
that directors of NCC shall not be liable personally to NCC or its stockholders
for monetary damages for breach of fiduciary duty as a director except for
liability arising out of (a) any breach of the director's duty of loyalty to NCC
or its stockholders, (b) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (c) payment of a dividend
or approval of a stock repurchase in violation of Section 174 of the DGCL or (d)
any transaction from which the director derived an improper personal benefit.
This provision protects NCC directors against personal liability for monetary
damages from breaches of their duty of care. Under Delaware law, absent adoption
of Article Seventh, directors can be held liable for gross negligence in
connection with decisions made on behalf of the corporation in the performance
of their duty of care, but may not be liable for simple negligence. Although
Article Seventh provides NCC directors with protection from certain awards of
monetary damages for breaches of their duty of care, it does not eliminate the
director's duty of care. Accordingly, Article Seventh has no effect on the
availability of equitable remedies, such as an injunction or rescission, based
upon a director's breach of his duty of care. Article Seventh does not apply to
officers of NCC who are not directors of NCC.
 
                                       62
<PAGE>   66
 
     Section 23-1-35-1 of the IBCL provides that directors of CIB shall not be
liable for any action taken or not taken as a director except for liability
arising out of (a) any breach or failure to perform the duties of the director's
office in good faith, with the care an ordinarily prudent person in a like
position would exercise under similar circumstances and in a manner reasonably
believed to be in the best interests of the corporation, and (b) any such breach
or failure to perform which constitutes willful misconduct or recklessness.
CIB's Articles of Incorporation extend similar protections to directors,
officers, employees and agents of CIB.
 
INDEMNIFICATION AND INSURANCE
 
     NCC. Under Section 145 of the DGCL, directors, officers, employees and
other individuals may be indemnified against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement in connection with
specified actions, suits or proceedings, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation --
a "derivative action") if they acted in good faith and in a manner they
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and, regarding any criminal action or proceeding, had no reasonable
cause to believe their conduct was unlawful. A similar standard is applicable in
the case of derivative actions, except that indemnification only extends to
expenses (including attorneys' fees) incurred in connection with the defense or
settlement of such actions. The DGCL requires court approval before there can be
any indemnification where the person seeking indemnification has been found
liable to the corporation. To the extent that a person otherwise eligible to be
indemnified is successful on the merits of any claim or defense described above,
indemnification for expenses (including attorneys' fees) actually and reasonably
incurred is mandated by the DGCL.
 
     Article VI of NCC's By-Laws provides that NCC must indemnify, to the
fullest extent authorized by the DGCL, each person who was or is made party to,
is threatened to be made a party to, or is involved in, any action, suit or
proceeding because he is or was a director, officer or employee of NCC or of any
NCC subsidiary (or was serving at the request of NCC as a director, trustee,
officer, employee or agent of another entity) while serving in such capacity
against all expenses, liabilities or loss incurred by such person in connection
therewith. The amount of any indemnification to which any person shall otherwise
be entitled under Article VI shall be reduced to the extent that such person
shall otherwise be entitled to valid and collectible indemnification provided by
a subsidiary of NCC or any other source.
 
     Article VI also provides that NCC may pay expenses incurred in defending
the proceedings specified above in advance of their final disposition. NCC may
advance expenses to any director, officer or employee only upon delivery to NCC
of an undertaking by the indemnified party stating that he has reasonably
incurred or will reasonably incur actual expenses in defending an actual civil
or criminal suit, action or proceeding in his capacity as such director, officer
or employee, or arising out of his status as such director, officer or employee,
and that he undertakes to repay all amounts so advanced if it is ultimately
determined that the person receiving such payments is not entitled to be
indemnified.
 
     Finally, Article VI provides that NCC may maintain insurance, at its
expense, to protect itself and any of its directors, officers, employees or
agents against any expense, liability or loss, regardless of whether NCC has the
power or obligation to indemnify that person against such expense, liability or
loss under the provisions of Article VI.
 
     The right to indemnification is not exclusive of any other right which any
person may have or acquire under any statute, provision of NCC's Certificate or
By-Laws, or otherwise. Additionally, no amendment to NCC's Certificate can
increase the liability of any director or officer for any act or omission by him
prior to such amendment.
 
     CIB. Chapter 37 of the IBCL provides for both mandatory and permissive
indemnification of CIB's directors, officers, employees and agents who are made
parties to proceedings as a result of conduct in their official capacity.
Chapter 37 requires CIB to indemnify any director or officer against reasonable
expenses incurred in the defense of such a proceeding generally if the
individual is wholly successful on the merits. Chapter 37 authorizes CIB to
indemnify any director, officer, employee or agent against liability incurred in
such a proceeding generally if the individual's conduct was in good faith and
the individual reasonably believed his conduct was in CIB's best interests.
Chapter 37 further authorizes any court of competent jurisdiction to order
indemnification generally if the court determines a director or officer is
entitled to mandatory indemnification or
 
                                       63
<PAGE>   67
 
is otherwise fairly and reasonably entitled to indemnification in view of all
the relevant circumstances. Chapter 37 authorizes indemnification to reimburse
reasonable expenses in advance of final disposition of a proceeding generally if
the individual affirms in writing a good faith belief he satisfies the standard
of conduct for permissive indemnification, the individual undertakes in a signed
writing to repay the advance if it is determined he does not satisfy the
standard of conduct for permissive indemnification and CIB determines that the
facts then known do not preclude indemnification. Lastly, Chapter 37 authorizes
further indemnification to the extent that CIB may provide in its Articles of
Incorporation, By-laws, Board of Directors or shareholder resolution, or other
authorization adopted by a majority vote of its voting shares then issued and
outstanding.
 
     Article 13 of CIB's Articles of Incorporation generally provides for
indemnification of any person who is or was a director, officer, employee, or
agent of CIB, or who served at CIB's request as a director, officer, employee,
partner, trustee, employee or agent of another corporation, partnership, joint
venture, trust, employee benefit plan, or other enterprise. To qualify for
indemnification, such a person generally must have been successful on the merits
or otherwise, or (i) must have acted in good faith and in a manner he reasonably
believed, in the case of conduct in his official capacity, was in the best
interest of CIB, and, in all other cases, was not opposed to CIB's best
interests and (ii) in any criminal proceeding, either had reasonable cause to
believe that his conduct was lawful or had no reasonable cause to believe that
his conduct was unlawful. A person who qualifies for indemnification generally
is entitled to indemnity for any obligation to pay any judgments, settlements,
penalties, fines and expenses actually or reasonably incurred in any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, and whether formal or informal, in which he or
she was made a party as a result of his or her service on behalf of CIB.
 
     To the extent that a director, officer, employee or agent of CIB has been
successful, on the merits or otherwise, in the defense of any action, suit or
proceeding, or in the defense of any claim, issue or matter therein, CIB shall
indemnify such person against expenses (including counsel fees) actually and
reasonably incurred by such person in connection therewith. Any other
indemnification (unless ordered by a court) shall be made by CIB only as
authorized in the specific case, upon the determination that indemnification of
the director, officer, employee or agent is permissible in the circumstances
because he has met the applicable standard of conduct. Such determination shall
be made (1) by the Board of Directors by a majority vote of a quorum consisting
of directors who were not at the time parties to such action, suit or
proceeding; or (2) if a quorum cannot be obtained under subdivision (1), by a
majority vote of a committee duly designated by the Board of Directors (in which
designation directors who are parties may participate), consisting solely of two
or more directors not at the time parties to such action, suit or proceeding; or
(3) by special legal counsel: (A) selected by the Board of Directors or its
committee in the manner prescribed in subdivision (1) or (2), or (B) if a quorum
of the Board of Directors cannot be obtained under subdivision (1) and a
committee cannot be designated under subdivision (2), selected by a majority
vote of the full Board of Directors (in which selection directors who are
parties may participate); or (4) by the shareholders, but shares owned by or
voted under the control of directors who are at the time parties to such action,
suit or proceeding may not be voted on the determination.
 
     Authorization of indemnification and evaluation as to reasonableness of
expenses shall be made in the same manner as the determination that
indemnification is permissible, except that if the determination is made by
special legal counsel, authorization of indemnification and evaluation as to
reasonableness of expenses shall be made by those entitled under subsection (3)
to select counsel.
 
ANTITAKEOVER STATUTES
 
     Delaware Business Combination Statute. Section 203 of the DGCL ("Section
203"), which applies to NCC, regulates transactions with major stockholders
after they become major stockholders. Section 203 prohibits a Delaware
corporation from engaging in mergers, dispositions of 10% or more of its assets,
issuances of stock and other transactions ("business combinations") with a
person or group that owns 15% or more of the voting stock of the corporation (an
"interested stockholder"), for a period of three years after the interested
stockholder crosses the 15% threshold. These restrictions on transactions
involving an interested stockholder do not apply if (a) before the interested
stockholder owned 15% or more of the voting stock, the board of directors
approved the business combination or the transaction that resulted in the person
or group becoming an interested stockholder; (b) in the transaction that
resulted in the person or group becoming an interested stockholder, the person
or group acquired at least 85% of the voting stock other than stock owned by
inside directors and certain employee stock
 
                                       64
<PAGE>   68
 
plans; (c) after the person or group became an interested stockholder, the board
of directors and at least two-thirds of the voting stock other than stock owned
by the interested stockholder approves the business combination; or (d) certain
competitive bidding circumstances.
 
     Indiana Control Share Acquisitions Statute. Chapter 42 of the IBCL, the
Indiana Control Share Acquisitions Statute, restricts the voting rights of
certain shares ("control shares") that, except for Chapter 42, would have voting
power with respect to shares of an issuing public corporation and that, when
added to all other shares of such corporation owned by a person, would entitle
that person, immediately after the acquisition of such shares, to exercise or
direct the exercise of the voting power of such corporation in the election of
directors within any of the following ranges of voting power: (a) one-fifth or
more but less than one-third of all voting power; (b) one-third or more but less
than a majority of all voting power; and (c) a majority or more of all voting
power (a "control share acquisition"). The voting rights of such control shares
are restricted to those rights granted by a resolution approved by the holders
of a majority of the outstanding voting shares, excluding the voting shares
owned by the acquiring shareholder and certain other "interested shares," which
includes shares owned by officers of the issuing corporation and employees of
the issuing corporation that are also directors of the issuing corporation.
 
     Chapter 42 does not apply to the acquisition of shares of an issuing public
corporation if the acquisition is consummated (a) before January 8, 1986; (b)
pursuant to a contract existing before January 8, 1986; (c) pursuant to the laws
of descent and distribution; (d) pursuant to a satisfaction of a pledge or other
security interest created in good faith and not for the purposes of
circumventing the statute; or (e) pursuant to a merger or plan of shares
exchange effected in compliance with IBCL Section 23-1-40 if the issuing public
corporation is a party to the agreement of merger or plan of share exchange.
Because CIB, as the issuing corporation, is a party to the Merger, which is
being effected in compliance with IBCL Section 23-1-40, NCC's acquisition of CIB
shares in connection with the Merger will not be considered a control share
acquisition.
 
     Indiana Business Combination Statute.  Chapter 43 of the IBCL is similar,
but not identical, to Section 203 of the DLGL. Chapter 43 prohibits Indiana
corporations from engaging in certain transactions (including mergers,
consolidations, asset sales, liquidations or dissolutions, reclassifications,
recapitalizations, disproportionate share conversions, loans, advances, other
financial assistance, or tax benefits not received proportionately by all
shareholders) (each, a "business combination") with a person that is the
beneficial owner, directly or indirectly, of 10% or more of the voting power of
the outstanding voting shares of the Indiana corporation (an "interested
shareholder") for a period of five years after such person becomes an interested
shareholder unless, prior to the date the interested shareholder becomes an
interested shareholder, the board of directors of the Indiana corporation
approves either the transaction in which such person becomes an interested
shareholder or such business combination. Following the five-year moratorium
period, the Indiana corporation may engage in certain business combinations with
an interested shareholder only if, among other things, (a) the business
combination is approved by the affirmative vote of the holders of a majority of
the outstanding voting shares not beneficially owned by the interested
shareholder proposing the business combination or (b) the business combination
meets certain criteria designed to ensure that the remaining shareholders
receive fair consideration for their shares. Chapter 43 of the IBCL will not
apply to the Merger Agreement or the grant or exercise of the Option because
CIB's Board of Directors approved the Merger Agreement prior to the date of the
granting of the Option.
 
     Other Provisions.  The IBCL also specifically authorizes directors, in
considering the best interests of an Indiana corporation, to consider the
effects of any action on shareholders, employees, suppliers, and customers of
the corporation, and communities in which offices or other facilities of the
corporation are located, and any other factors the directors consider pertinent.
Under the IBCL, directors are not required to approve a proposed business
combination or other corporate action if the directors determine in good faith
that such approval is not in the best interest of the corporation. In addition,
the IBCL states that directors are not required to redeem any rights under, or
render inapplicable, a shareholder rights plan or to take or decline to take any
other action solely because of the effect such action might have on a proposed
change of control of the corporation or the amounts to be paid to shareholders
upon such change of control. The IBCL explicitly provides that the different or
higher degree of scrutiny imposed in Delaware and certain other jurisdictions
upon director actions taken in response to
 
                                       65
<PAGE>   69
 
potential changes in control will not apply. The Delaware Supreme Court has held
that defensive measures in response to a potential takeover must be "reasonable
in relation to the threat posed."
 
     In taking or declining to take any action or in making any recommendation
to a corporation's shareholders with respect to any matter, directors are
authorized under the IBCL to consider both the short-term and long-term
interests of the corporation as well as interests of other constituencies and
other relevant factors. Any determination made with respect to the foregoing by
a majority of the disinterested directors shall conclusively be presumed to be
valid unless it can be demonstrated that such determination was not made in good
faith after reasonable investigation.
 
     Because of the foregoing provisions of the IBCL, the board of directors of
an Indiana corporation will have flexibility in responding to unsolicited
acquisition proposals, and accordingly it may be more difficult for an acquiror
to gain control of the corporation in a transaction not approved by the board.
 
ISSUANCE OF PREFERRED STOCK
 
     NCC's Certificate and CIB's Articles authorize the Board of Directors of
the respective companies to issue shares of preferred stock, from time to time,
in one or more series as the Boards of Directors may determine, and to fix the
relative powers, preferences and rights (including voting rights) of each such
series of preferred stock in relation to the powers, preferences and rights of
any other series of preferred stock. Voting rights, if any, may be general,
special, conditional or limited. The Boards of Directors of NCC and CIB also
have the discretion to determine the number of votes per share which each holder
of a share of a series of the preferred stock will have, but in no event may any
holder of any series of NCC preferred stock be entitled to more than one vote
per share. Additionally, the Boards of Directors of NCC and CIB are authorized
to permit the holders of a series of preferred stock to vote separately or
together with the holders of one or more other series of preferred stock on all
or some matters as a separate voting group. Except with respect to the number of
votes per share, NCC's Certificate does not materially differ from the
provisions of CIB's Articles with respect to the ability of the Boards of
Directors of NCC and CIB to issue preferred stock in one or more series and to
fix the relative powers, preferences and rights of each such series in relation
to the powers, preferences and rights of any other series of preferred stock.
The power of the Boards of Directors of NCC and CIB to issue preferred stock
with voting or other powers, preferences and rights may be used to impede or
discourage a takeover attempt. See "DESCRIPTION OF NCC CAPITAL STOCK --
Preferred Stock" and "DESCRIPTION OF CIB CAPITAL STOCK -- Preferred Stock --
General."
 
     Generally, the issuance of preferred stock by NCC could (a) result in a
class of securities outstanding which will have certain preferences regarding
distributions in a liquidation over NCC Common and might provide for certain
rights (whether general, special, conditional or limited) that could dilute the
voting rights of NCC Common and (b) result in dilution of the net income per
share and net book value per share relating to NCC Common. Further, the issuance
of any additional shares of NCC Common, pursuant to any conversion rights
granted holders of any preferred stock, may also result in dilution of the
voting rights, net income per share and net book value of NCC Common.
 
     Specifically, the terms of NCC's New Preferred Stock provide that in the
event of any voluntary or involuntary liquidation, dissolution or winding up of
NCC, the holders of shares of New Preferred Stock are entitled to receive out of
the assets of NCC available for distribution to stockholders, before any
distribution of assets is made to holders of NCC Common, liquidation
distributions in the amount of $250 per share (equivalent to $50 per Depositary
Share) plus accrued and unpaid dividends. Additionally, if the equivalent of six
quarterly dividends payable on the New Preferred Stock is in arrears, the number
of directors of NCC will be increased by two, and the holders of New Preferred
Stock will be entitled to elect two directors to fill such vacancies. Such right
to elect two additional directors shall continue until all dividends in arrears
have been paid or declared and set apart for payment. Finally, shares of New
Preferred Stock are convertible at any time at the option of the holder thereof
into shares of NCC Common at a conversion price of $20.975 per share of NCC
Common (equivalent to a conversion rate of approximately 11.919 shares of NCC
Common for each share of New Preferred Stock and 2.384 shares for each
Depository Share). See "DESCRIPTION OF NCC CAPITAL STOCK -- Preferred Stock."

CUMULATIVE VOTING
 
     Section 214 of the DGCL provides that no cumulative voting rights, in
respect of elections of directors, exist under Delaware Law, unless a
corporation's certificate of incorporation provides otherwise. NCC's Certificate
does not provide for cumulative voting in elections of directors.
 
     Section 23-1-30 of the IBCL also provides that shareholders do not have the
right to cumulate their votes for directors unless a corporation's articles of
incorporation so provide. CIB's Articles do not provide for cumulative voting in
election of directors.
 
ACTION WITHOUT A MEETING
 
     Section 228 of the DGCL permits any action required or permitted to be
taken at a stockholder's meeting to be taken by written consent signed by the
holders of the number of shares that would have been required to effect the
action at an actual meeting of the stockholders. Generally, holders of a
majority of outstanding shares can effect such an action. The DGCL also provides
that a corporation's certificate of incorporation may restrict or even prohibit
stockholders' action without a meeting. NCC's Certificate does not restrict or
prohibit stockholders' action without a meeting.
 
     Under Section 23-1-29-4 of the IBCL, any action required or permitted to be
taken at a shareholders' meeting may be taken without a meeting by written
consent signed by all of the shareholders entitled to vote on such action.
 
SPECIAL MEETINGS
 
     Under Section 211(d) of the DGCL, the board of directors or those persons
authorized by the corporation's certificate of incorporation or by-laws may call
a special meeting of the corporation's stockholders. NCC's By-Laws provide that
a special meeting may be called by the Chairman of the Board and must be called
by the Chairman of the Board or Secretary at the request in writing of a
majority of the Board of Directors, or at the request in writing of stockholders
owning a majority in amount of the entire capital stock of NCC issued and
outstanding and entitled to vote.
 
     In comparison, Section 23-1-29-2 of the IBCL requires a corporation of 50
or more shareholders to hold a special meeting on call of its board of directors
or the person or persons (including, but not limited to, shareholders or
officers) specifically authorized to do so by the articles of incorporation or
bylaws. CIB's By-Laws provide that a special meeting may only be called by the
Chairman of the Board of CIB or pursuant to a resolution adopted by a majority
of the total number of directors of CIB. Shareholders are not authorized to call
a special meeting.
 
VOTING, APPRAISAL RIGHTS AND CORPORATE REORGANIZATIONS
 
     The DGCL generally requires a majority vote of stockholders to approve a
merger, sale of assets or similar reorganization transaction. Under Section
251(f) of the DGCL, however, no vote of the stockholders of a corporation
surviving the merger is required if the number of shares to be issued in the
merger does not exceed 20% of the shares of the surviving corporation
outstanding immediately prior to the date of the merger and if certain other
conditions are met. The adoption and approval of the Merger Agreement by the
stockholders of NCC is not required under the DGCL.
 
     Section 262 of the DGCL does not provide for dissenters' rights of
appraisal for (a) the sale, lease or exchange of all or substantially all of the
assets of a corporation, (b) a merger by a corporation, the shares of which are
either listed on a national securities exchange or held by more than 2,000
stockholders if such stockholders receive shares of the surviving corporation or
of a listed or widely held corporation or (c) stockholders of a corporation
surviving a merger if no vote of such stockholders is required to approve the
merger. See "MERGER -- Appraisal and Dissenters' Rights -- NCC."
 
     The IBCL also requires a majority vote of shareholders to approve a plan of
merger or share exchange. This requirement is modified by CIB's Articles of
Incorporation in one significant respect. CIB's Articles of Incorporation
require that certain business combinations between CIB (or any majority-owned
subsidiary thereof)
 
                                       67
<PAGE>   71
 
and a 10% or greater shareholder either (i) be approved by at least 80% of the
total number of outstanding voting shares of CIB, or (ii) be approved by a
majority of certain directors unaffiliated with such 10% or greater shareholder
or involve consideration per share generally equal to the higher of (A) the
highest amount paid by such 10% shareholder or its affiliates in acquiring any
shares of the CIB Common or (B) the "Fair Market Value" (generally, the highest
closing sale price of the CIB Common during the thirty days preceding the date
of the announcement of the proposed business combination or on the date the 10%
or greater shareholder became such, whichever is higher). The adoption of the
Merger Agreement by the affirmative vote of the holders of the majority of the
shares of CIB Common eligible to vote is a condition to the parties' obligation
to close.
 
     Section 23-1-44-8 of the IBCL does not provide for dissenters' rights for a
merger or plan of share exchange by a corporation the shares of which are (a)
registered on a United States securities exchange registered under the Exchange
Act, or (b) traded on NASDAQ or a similar market. See "MERGER -- Appraisal and
Dissenters' Rights -- CIB."
 
     Limitations on 10% Shareholders.  CIB's Articles of Incorporation provide
that for a period of five years following the date on which CIB issued its first
share of capital stock (i.e., until July 1, 1996): (i) no person shall directly
or indirectly offer to acquire or acquire the beneficial ownership of more than
10% of any class of equity security of CIB (provided that such limitation shall
not apply to the acquisition of equity securities by any one or more
tax-qualified employee stock benefit plans maintained by CIB, if the plan or
plans beneficially own no more than 25% of any class of such equity security of
CIB); and that (ii) shares beneficially owned in violation of the stock
ownership restriction described above shall not be entitled to vote and shall
not be voted by any person or counted as voting stock in connection with any
matter submitted to a vote of shareholders. For these purposes, a person
(including management) who has obtained the right to vote shares of the CIB
Common pursuant to revocable proxies shall not be deemed to be the "beneficial
owner" of those shares if that person is not otherwise deemed to be a beneficial
owner of those shares.
 
     Amendments to Charter Documents.  The DGCL requires approval of
stockholders holding a majority of the voting power of NCC in order to amend
NCC's Certificate. Amendments to CIB's Articles of Incorporation must be
approved by a majority vote of CIB's Board of Directors and also by a majority
of the outstanding shares of CIB's voting shares; provided, however, that
approval by at least 80% of the outstanding voting shares is required for
certain provisions (i.e., provisions relating to number, classification, and
removal of directors; amendment of the By-laws; call of special shareholder
meetings; criteria for evaluating certain offers; certain business combinations;
and amendments to provisions relating to the foregoing). The provisions
concerning limitations on the acquisition of shares which are in effect for a
five-year period may be amended only by an 80% vote of CIB's outstanding shares
unless at least two-thirds of CIB's Continuing Directors (directors of CIB on
March 15, 1991, or directors recommended for appointment or election by a
majority of such directors) approve such amendments in advance of their
submission to a vote of shareholders (in which case only the vote required by
the IBCL is required).
 
BY-LAWS
 
     Section 109 of the DGCL places the power to adopt, amend or repeal by-laws
in the corporation's shareholders, but permits the corporation, in its
certificate of incorporation, also to vest such power with the board of
directors. NCC's Certificate contains such a provision. Although the Board of
Directors of NCC has been vested with such authority, NCC's stockholders' power
to adopt, amend or repeal by-laws remains unrestricted. CIB's Articles provide
that its by-laws may only be amended by a majority vote of the total number of
directors of CIB. This is consistent with IBCL Section 23-1-39-1, which provides
that the Board of Directors has the power to amend the by-laws unless the
Articles of Incorporation provide otherwise.
 
PREEMPTIVE RIGHTS
 
     Under Section 102 of the DGCL, no statutory preemptive rights will exist,
unless a corporation's certificate of incorporation specifies otherwise. NCC's
Certificate does not provide for any such preemptive rights.
 
                                       68
<PAGE>   72
 
     IBCL Section 23-1-27-1 provides that the shareholders of a corporation do
not have a preemptive right to acquire a corporation's unissued shares except to
the extent the articles of incorporation so provide. CIB's Articles do not
provide for any such preemptive rights.
 
DIVIDENDS
 
     Delaware corporations may pay dividends out of surplus or, if there is no
surplus, out of net profits for the fiscal year in which declared and for the
preceding fiscal year. Section 170 of the DGCL also provides that dividends may
not be paid out of net profits if, after the payment of the dividend, capital is
less than the capital represented by the outstanding stock of all classes having
a preference upon the distribution of assets.
 
     In comparison, the IBCL does not permit dividend distributions if, after
giving effect to the proposed dividend, (a) the corporation would be unable to
pay its debts as they become due in the ordinary course of business, or (b) the
corporation's total assets would be less than the sum of its total liabilities
plus (unless the articles of incorporation permit otherwise) the amount that
would be needed, if the corporation were to be dissolved at the time of
distribution, to satisfy the preferential rights (if any) of shareholders whose
preferential rights are superior to those shareholders receiving the
distribution.
 
     NCC is subject to the FRB policies regarding payment of dividends, which
generally limit dividends to operating earnings. See "CERTAIN REGULATORY
CONSIDERATIONS -- Payment of Dividends." Generally, there is no OTS regulatory
restriction on the payment of dividends by CIB absent a determination by the
Director of the OTS that there is reasonable cause to believe that the payment
of dividends constitutes a serious risk to the financial safety, soundness or
stability of Kokomo.
 
                                    EXPERTS
 
     The consolidated financial statements of NCC appearing in NCC's Annual
Report on Form 10-K for the year ended December 31, 1993, have been audited by
Ernst & Young, independent auditors, as set forth in their report thereon
included therein and incorporated herein by reference. Such consolidated
financial statements are incorporated herein by reference in reliance upon such
report given upon the authority of such firm as experts in accounting and
auditing.
 
     The consolidated financial statements of CIB included herewith have been
examined by Crowe, Chizek & Company as independent auditors for the periods
indicated in their Report of Independent Auditors dated October 24, 1994, and
have been included in reliance upon their report given upon their authority as
experts in auditing and accounting.
 
                                 LEGAL OPINIONS
 
     The validity of the NCC Common will be passed upon by Jones, Day, Reavis &
Pogue, North Point, 901 Lakeside Avenue, Cleveland, Ohio 44114, which has
banking relationships with certain banking subsidiaries of NCC.
 
     The Merger Agreement provides as a condition to the parties' obligation to
close that NCC and CIB shall have received the opinion of Barnes & Thornburg,
substantially to the effect, among other things, that no gain or loss will be
recognized by the shareholders of CIB who exchange their shares of CIB Common
solely for shares of NCC Common pursuant to the Merger (except with respect to
cash received in lieu of a fractional interest in NCC Common).
 
                      ANNUAL MEETING/SHAREHOLDER PROPOSALS
 
     If the Merger is not consummated, an Annual Meeting of Shareholders of CIB
is scheduled to be held on January 24, 1995. Any shareholder proposal to be
included in the proxy statement and form of proxy for that meeting had to have
been received by CIB at its principal executive offices no later than September
21, 1994. CIB will not be required to include in any proxy statement or form of
proxy any shareholder proposal that was not received prior to that date or that
fails to meet the Commission's requirements for shareholder proposals. If the
Merger is consummated, no Annual Meeting of Shareholders of CIB will be held.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Central Indiana Bancorp
Kokomo, Indiana
 
     We have audited the accompanying consolidated balance sheets of CIB as of
September 30, 1994 and 1993 and the related consolidated statements of income,
changes in stockholders' equity and cash flows for the years ended September 30,
1994, 1993 and 1992. These financial statements are the responsibility of CIB's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of CIB as of
September 30, 1994 and 1993, and the results of its operations and its cash
flows for the years ended September 30, 1994, 1993 and 1992 in conformity with
generally accepted accounting principles.
 
     As discussed in Notes 1 and 11 to the consolidated financial statements,
CIB changed its method of accounting for income taxes effective October 1, 1993.
Also, as discussed in Notes 1 and 10, CIB changed its method of accounting for
postretirement benefits other than pensions effective October 1, 1993.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 YEARS ENDED SEPTEMBER 30, 1994, 1993 AND 1992
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation:  The accompanying consolidated financial
statements include the accounts of CIB and its wholly-owned subsidiary, Kokomo,
and Kokomo's wholly-owned subsidiary, First Marketing, Inc. First Marketing,
Inc. offers various annuity and insurance programs to Bank customers and others.
All significant intercompany transactions and balances are eliminated in
consolidation.
 
     Concentrations of Credit Risk:  CIB grants residential, consumer and
commercial loans to customers primarily in central Indiana. A significant number
of CIB's customers work for employers who rely heavily on the automotive
industry. At September 30, 1994, loans secured primarily by residential and
commercial real estate mortgages comprise approximately 95% of the loan
portfolio and 3% is made up of consumer loans and commercial loans secured by
other assets. Approximately 2% of the loans are unsecured.
 
     Cash and Cash Equivalents:  For purposes of reporting cash flows, cash and
cash equivalents include cash on hand and due from other financial institutions,
federal funds sold, and funds invested in demand and overnight time accounts at
the Federal Home Loan Bank. Generally, federal funds are sold for one-day
periods. CIB reports net cash flows for customer loan transactions, deposit
transactions and deposits made with other financial institutions.
 
     Investment Securities:  Investment securities are carried at cost, adjusted
for amortization of premiums and accretion of discounts using the level yield
method. Management has the intent and CIB has the ability to hold such
investments to maturity.
 
     Gains and losses on the sale of investment securities are determined using
the specific identification method and are reflected in operations at the time
of sale.
 
     Equity securities that are nonmarketable are carried at cost. All other
equity securities are carried at the lower of cost or estimated market value in
the aggregate. Net unrealized losses are recognized through a valuation
allowance that is shown as a reduction in the carrying value of the related
securities and as a corresponding reduction in stockholders' equity. Investment
securities for which a decline in value is determined by management to be other
than temporary are written down with the loss recognized in the consolidated
statement of income.
 
     Mortgage-Backed Securities:  Mortgage-backed securities are stated at cost,
adjusted for amortization of premiums and accretion of discounts using the level
yield method. Management has the intent and CIB has the ability to hold such
investments to maturity. Gains and losses on the sale of mortgage-backed
securities are determined using the specific identification method.
 
     Loans Held for Sale:  Mortgage loans originated and intended for sale in
the secondary market are carried at the lower of cost or estimated market value
in the aggregate. Net unrealized losses are recognized in a valuation allowance
by charges to income.
 
     Recognition of Gains or Losses on the Sale of Loans:  Loans are sold on a
net yield basis, with servicing rights and obligations retained by CIB,
resulting in the recognition of gains or losses at the time of sale. CIB uses
the purchaser's normal servicing fee in computing these gains and losses.
 
     Loans Receivable:  Loans receivable are stated at unpaid principal
balances, less the allowance for loan losses, and net deferred loan origination
fees.

                                      CIB
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
                 YEARS ENDED SEPTEMBER 30, 1994, 1993 AND 1992
 
                                  (continued)
 
     The allowance for loan losses is increased by charges to income and
decreased by charge-offs (net of recoveries). Management's periodic evaluation
of the adequacy of the allowance is based on CIB's past loan loss experience,
known and inherent risks in the portfolio, adverse situations that may affect
the borrower's ability to repay, the estimated value of any underlying
collateral, and current economic conditions.
 
     Interest income on loans is accrued over the term of the loans based upon
the principal outstanding except when serious doubt exists as to the
collectibility of a loan, in which case the accrual of interest is discontinued.
Income is subsequently recognized only to the extent that cash payments are
received until, in management's judgment, the borrower has the ability to make
periodic interest and principal payments in which case the loan is returned to
accrual status.
 
     Loan Origination Fees, Commitment Fees, and Related Costs:  Loan fees are
accounted for in accordance with Statement of Financial Accounting Standards No.
91. Loan fees and certain direct loan origination costs are deferred, and the
net fee or cost is recognized as an adjustment to interest income using the
level yield method over the contractual life of the loans adjusted for
prepayments.
 
     Foreclosed Real Estate:  Real estate properties acquired through, or in
lieu of, loan foreclosure are initially recorded at fair value at the date of
foreclosure. Costs relating to development and improvement of property are
capitalized, whereas costs relating to the holding of property are expensed.
 
     Valuations are periodically performed by management, and an allowance for
losses is established by a charge to income if the carrying value of a property
exceeds its estimated fair value less selling costs.
 
     Income Taxes:  Effective October 1, 1993, Kokomo adopted SFAS No. 109,
"Accounting for Income Taxes". The Bank records income tax expense based on the
amount of taxes due on its tax return, plus deferred taxes computed based on the
expected future tax consequences of temporary differences between the carrying
amounts and tax bases of assets and liabilities, using enacted tax rates.
Previously, the Bank computed deferred taxes for the tax effects of timing
differences between financial reporting and tax return income. The cumulative
effect of the change in accounting for income taxes is reported in the September
30, 1994 statement of income.
 
     Postretirement Benefits Other Than Pensions:  Effective October 1, 1993,
CIB adopted Statement of Financial Accounting Standards No. 106 "Employers'
Accounting for Postretirement Benefits Other Than Pensions" ("SFAS 106"). SFAS
106 requires the accrual of the expected cost of providing postretirement
benefits to employees during the years that the employees render services.
Previously, Kokomo expensed the costs of postretirement benefits as they were
incurred. The cumulative effect of the change in accounting for postretirement
benefits other than pensions is reported in the September 30, 1994 statement of
income, net of tax.
 
     Premises and Equipment:  Land is carried at cost. Buildings and furniture,
fixtures, and equipment are carried at cost, less accumulated depreciation.
Premises and related components are depreciated primarily on the straight-line
method with useful lives ranging from 20 to 67 years. Furniture and equipment
are depreciated on either the straight-line or sum-of-the-years digits methods
with useful lives ranging from 5 to 18 years. Maintenance and repairs are
charged to expense as incurred, and improvements which extend the useful lives
of assets are capitalized.
 
     Net Assets of Acquired Financial Institution in Excess of Cost of
Investment:  This item represents the value of negative goodwill remaining from
the acquisition of Peru in 1994. The value is being amortized using the straight
line method over ten years.

                 YEARS ENDED SEPTEMBER 30, 1994, 1993 AND 1992
 
     Earnings Per Share:  Earnings per share is computed by dividing net income
by the weighted average number of shares of common stock outstanding. The
weighted average number of shares outstanding for the calculation of earnings
per shares were 1,631,722, 1,501,056 and 1,481,209 for the years ended September
30, 1994, 1993 and 1992. The effect of common stock equivalents is not material
to the periods reported.
 
     Stock Split:  On April 20, 1993, the Board of Directors declared a 4 for 3
stock split under which every three shares of CIB's common stock outstanding at
the close of business on April 30, 1993, were converted into four shares of
common stock. No fractional shares were issued; cash in lieu of fractional
shares was paid to stockholders. Per share and shares outstanding amounts for
September 30, 1993 and 1992 have been adjusted to give effect to the 4 for 3
stock split.
 
     Reclassifications:  Certain amounts appearing in the 1993 and 1992
consolidated financial statements and notes thereto have been reclassified to
conform with the September 30, 1994 presentation.

NOTE 9 -- EMPLOYEE PENSION AND THRIFT PLANS
 
     Kokomo is part of a noncontributory multiple-employer pension plan which
covers all Kokomo employees who have completed one year of employment and meet
certain minimum hour requirements during a calendar year. The plan is
administered by the trustees of the Financial Institutions Retirement Fund.
Because it is a multiple-employer plan, there is no separate valuation of plan
benefits nor segregation of plan assets specifically for Kokomo. However, as of
June 30, 1993, the date of the latest actuarial valuation, the total plan assets
exceeded the actuarially determined value of total accrued benefits.
 
     The cost of the plan is set annually as an established percentage of wages.
During fiscal years 1994, 1993 and 1992, CIB contributed approximately $158,000,
$168,000 and $17,000, respectively, to the Retirement Fund. As a result, CIB
recognized $144,000, $114,000 and $17,000 of pension expense in fiscal 1994,
1993 and 1992, respectively.
 
     CIB is also a participant in the Financial Institutions Thrift Plan, a tax
exempt, trusteed savings plan. All contributions to the plan are invested for
the benefit of all participants, with an individual account maintained for each
participant. Employees are eligible for membership in the plan after completing
one year of employment and meeting certain minimum hour requirements. Kokomo
contributes an amount equal to 50% of each employee's monthly contribution,
limited to 6% of basic monthly salary for the year ended September 30, 1994 and
3% for the years ended September 30, 1993 and 1992. Contributions are charged to
expense and amounted to $85,085, $37,832 and $34,464 for the years ended
September 30, 1994, 1993 and 1992, respectively. During fiscal years 1993 and
1992, CIB also charged to expense an additional $39,185 and $34,800,
respectively, for a supplementary annual contribution to members' thrift plan
accounts. This amounted to an additional 3% of basic annual salary.

NOTE 10 -- OTHER POSTRETIREMENT BENEFIT PLANS
 
     CIB sponsors a defined benefit postretirement plan that provides medical
benefits to eligible employees and directors. Currently, retirees who are at
least age 55 with a combination of years of service and age which equals 85 and
their spouses and children are eligible for postretirement medical benefits with
premiums subsidized by CIB. In addition, employees who are at least age 55 and
have at least ten years of service may retain postretirement medical benefits by
reimbursing CIB for premiums.
 
     The following table sets forth the plans' combined funded status reconciled
with the amount shown in CIB's balance sheet at September 30, 1994:

</TABLE>
 
     For measurement purposes, a   % annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1994; the rate was assumed
to decrease gradually to   % after   years and remain at that level thereafter.
The health care cost trend rate assumption has a significant effect on the
amounts reported. To illustrate, increasing the assumed health care cost trend
rates by 1% in each year would increase the accumulated postretirement benefit
obligation as of September 30, 1994 by $          and the aggregate of the
service and interest cost components of net periodic postretirement benefit cost
for the year then ended by $          . The weighted-average discount rate used
in determining the accumulated postretirement benefit obligation was           .
 
NOTE 11 -- INCOME TAXES
 
     CIB files consolidated federal income tax returns on a fiscal year basis.
If certain conditions are met in determining taxable income, CIB is allowed a
special bad debt deduction based on a percentage of taxable income (presently
8%) or on specified experience formulas. CIB used the
percentage-of-taxable-income method for all periods presented.

for tax purposes only. Reduction of amounts so allocated for purposes other than
tax bad debt losses or adjustments arising from carryback of net operating
losses would create income for tax purposes only, which would be subject to the
then-current corporate income tax rate. The unrecorded deferred income tax
liability on the above amounts was approximately $2,142,000 at September 30,
1994.
 
     Effective October 1, 1993, CIB has adopted Statement of Financial
Accounting Standard No. 109, "Accounting for Income Taxes". The adjustment to

included in income for the year ended September 30,1994.
 
NOTE 12 -- FINANCIAL INSTITUTIONS REFORM, RECOVERY AND ENFORCEMENT ACT (FIRREA
           OF 1989)
 
     FIRREA was signed into law on August 9, 1989; regulations for savings
institutions' minimum-capital requirements went into effect on December 7, 1989.
In addition to the capital requirements, FIRREA includes provisions for changes
in the federal regulatory structure for institutions, including a new deposit
insurance system, increased deposit insurance premiums, and restricted
investment activities with respect to non-investment-grade corporate debt and
certain other investments. FIRREA also increases the required ratio of
housing-related assets needed to qualify as a savings institution.
 
     The regulations require institutions to have minimum regulatory tangible
capital equal to 1.5% of total tangible assets, 3% core capital ratio, and an
8.0% risk-based capital ratio.
 
     Kokomo, at September 30, 1994, meets the regulatory tangible capital, core
capital and risk-based capital requirements as defined by FIRREA. At September
30, 1994, Kokomo's regulatory tangible capital was $31,923,000 or 13.31% of
total tangible assets; core capital was $31,923,000 or 13.31% of total tangible
assets; and risk-based capital was $33,587,000 or 24.85% of total risk-adjusted
assets, as defined by FIRREA.
 
     The following is a reconciliation of Kokomo capital under generally
accepted accounting principles (GAAP) to regulatory capital. Amounts reflected
relate to capital of Kokomo only and do not include capital of CIB as the
regulatory requirements listed are applicable to Kokomo.

     At the time of the conversion to stock, Kokomo established a liquidation
account in an amount equal to its net worth as of the date of the latest
consolidated financial statements contained in the final offering circular used
to sell the common stock ($16,512,340 [unaudited] at December 31, 1990). The
liquidation account will be maintained for the benefit of depositors, with
deposits of at least $50, as of the September 30, 1990 eligibility

record date, who continue to maintain their deposits in Kokomo after conversion.
In the event of a complete liquidation (and only in such an event), each
eligible depositor will be entitled to receive a liquidation distribution from
the liquidation account, in the proportionate amount of the then current
adjusted balance for deposits then held, before any liquidation distribution may
be made with respect to the stockholders. Except for the repurchase of stock and
payment of dividends by Kokomo, the existence of the liquidation account will
not restrict the use or application of net worth.
 
     Regulations of the OTS limit the amount of dividends and other capital
distributions that may be paid by a savings institution without prior approval
of the OTS. This regulatory restriction is based on a three-tiered system with
the greatest flexibility being afforded to well-capitalized (Tier 1)
institutions. Kokomo is currently a Tier 1 institution. Accordingly, Kokomo can
make, without prior regulatory approval, distributions during a calendar year up
to 100% of its net income during that calendar year plus the amount that would
reduce by one-half its "surplus capital ratio" (the excess over its Fully
Phased-In Capital Requirements) at the beginning of the calendar year.
Accordingly, at September 30, 1994, Kokomo had available approximately $11.7
million for distribution to CIB.

NOTE 15 -- STOCK OPTIONS AND EMPLOYEE STOCK PURCHASE PLAN
 
     On January 28, 1992, the stockholders approved the Stock Option Plan for
certain directors, officers and other key employees of CIB and its subsidiaries.
The plan limits the number of shares granted under options to 145,666 total
shares. The plan allows options to be granted with purchase prices of not less
than 75% and not more than 100% (110% for holders of more than 10% of the
combined voting power of all classes of stock) of fair market value of the
shares as of the date the options are granted. The stock options were granted at
market value at the date of grant. The exercise period for each option is
determined when granted, but may not exceed ten years for employees and ten
years and one day for outside directors from the date of grant (five years for
holders of more than 10% of the combined voting power of all classes of stock).
 
     On September 24, 1993, CIB's Board of Directors adopted the Central Indiana
Bancorp 1993 Stock Option Plan (the "New Option Plan"). The New Option Plan
became effective January 21, 1994 upon the merger conversion of Peru. The New
Option Plan limits the number of shares available for grant to 10% of shares
sold in the merger conversion which equaled 17,582 shares.

     On January 28, 1992, the stockholders approved the Employee Stock Purchase
Plan for all full-time employees who have attained the age of 21 and who have
completed one year of employment. Employee voluntary contributions are invested
in shares of CIB's stock. Voluntary contributions are limited to a minimum of $5
and a maximum of 10% of the employee's compensation per pay period.
 
     The effect of the above option plans on the earnings per share calculation
shown on the statement of income is not dilutive.
 
     Other than administrative expenses, CIB did not recognize any expense
relative to these plans for fiscal years ending September 30, 1994, 1993 and
1992.

     Since certain commitments to make loans and lines of credit and fund loans
in process expire without being used, the amount does not necessarily represent
future cash commitments. In addition, commitments to extend credit are
agreements to lend to a customer as long as there is no violation of any
condition established in the contract. No losses are anticipated as a result of

     The extent to which CIB may pay cash dividends to shareholders will depend
on the cash currently available at CIB as well as the Kokomo's ability to pay
dividends to CIB (see Note 12).
 
NOTE 19 -- ACQUISITION AND STOCK OFFERING
 
     On January 19, 1994 an agreement to acquire Peru became effective. The
merger/conversion transaction provided for Peru to convert from a mutual to
stock form of ownership. Eligible account holders of Peru had the right to
subscribe for and purchase common stock to be issued by CIB. As a result of the
merger/conversion, Peru merged into Kokomo and became a division of Kokomo,
which will remain a wholly-owned subsidiary of CIB.
 
     As of December 31, 1993, Peru had consolidated total assets of $
and equity of $          based on unaudited financial statements. For 1993, Peru
had net income of $          . CIB will account for the transaction under the
purchase method. Net income for CIB for the years ended September 30, 1994 and
1993 would have been approximately $3,027,000 and $2,051,000 had the transaction
occurred on October 1, 1993 or October 1, 1992, respectively.
 
NOTE 20 -- FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     A new accounting standard prescribes that CIB disclose the estimated fair
value of its financial instruments. The following table shows those values and
the related carrying values at September 30, 1994. Items which are not financial
instruments are not included.

</TABLE>
 
     For purposes of the above disclosures of estimated fair value, the
following assumptions were used as of September 30, 1994 and 1993. The estimated
fair value for cash and cash equivalents and interest earning time deposits in
other financial institutions is considered to approximate cost. The estimated
fair value for investment securities and mortgage-backed securities is based on
quoted market values for the individual securities or for equivalent securities.
The estimated fair value for loans (including loans held for sale) is based on
estimates of the difference in interest rates Kokomo would charge the borrowers
for similar such loans with similar maturities made at September 30, 1994 and
1993, applied for an estimated time period until the loan is assumed to reprice
or be paid. The estimated fair value for demand and savings deposits is based on
their carrying value. The

                 YEARS ENDED SEPTEMBER 30, 1994, 1993 AND 1992
 
estimated fair value for time deposits is based on the rate Kokomo would pay on
such deposits at September 30,
1994 and 1993, applied for the time period until maturity. The estimated fair
value of advances from borrowers for taxes and insurance is based on their
carrying value. The estimated fair value of net assets of acquired financial
institution in excess of cost of investment is based on its carrying value. The
estimated fair value for other financial instruments and off-balance-sheet loan
commitments are considered to approximate cost at September 30, 1994 and are not
considered significant to this presentation.
 
     While these estimates of fair value are based on management's judgment of
the most appropriate factors, there is no assurance that were CIB to have
disposed of such items at September 30, 1994 and 1993, the estimated fair values
would necessarily have been achieved at that date, since market value may differ
depending on various circumstances. The estimated fair values at September 30,
1994 and 1993 should not necessarily be considered to apply at subsequent dates.
 
     In addition, other assets and liabilities of CIB that are not defined as
financial instruments are not included in the above disclosures, such as
premises and equipment, foreclosed real estate, federal income taxes, and
accrued expenses. Also, non-financial instruments typically not recognized in
the financial statements nevertheless may have value but are not included in the
above disclosures. These include, among other items, the estimated earnings
power of core deposit accounts, the earnings potential of loan servicing rights,
the trained work force, customer goodwill, and similar items.

                          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>   103
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>   104





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>   105





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>   106





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>   107





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>   108





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.

                 III.  REPRESENTATIONS AND WARRANTIES OF NCC
                       -------------------------------------
         NCC hereby represents and warrants to Company that:
         3.1  CORPORATE ORGANIZATION.  NCC is a corporation duly organized,
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
shares of NCC preferred stock.  As of the close of business on July 22, 1994
(i) 150,218,833 shares of NCC Common Stock were validly issued and outstanding,
fully paid and nonassessable and (ii) 757,160 shares of eight percent (8%)
Cumulative Convertible Preferred Stock (issued as 3,785,800 Depositary Shares)





                                      -8-
<PAGE>   110





no par of NCC ("NCC Preferred Stock") were validly issued and outstanding,
fully paid and nonassessable.  As of the date hereof, except as set forth in
this Section 3.3, pursuant to the exercise of employee stock options under
NCC's Amended and Restated 1973 Stock Option Plan, as amended, the 1984 Stock
Option Plan, as amended, the 1989 Stock Option Plan and the 1993 Stock Option
Plan, NCC's dividend reinvestment plan, National City Savings and Investment
Plan and stock grants made pursuant to the NCC 1991 Amended and Second Restated
Restricted Stock Plan, or set forth in a disclosure letter executed by NCC and
dated and delivered by NCC to Company as of the date hereof ("NCC Disclosure
Letter"), there are no other shares of capital stock of NCC authorized, issued
or outstanding and  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 NCC obligating NCC to issue, deliver or sell, or cause to be issued,
delivered or sold, additional shares of capital stock of NCC or obligating NCC
to grant, extend or enter into any subscription, option, warrant, right,
convertible security or other similar agreement or commitment.  As of the date
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
shares of NCC Common Stock issuable in exchange for the Company Common Stock at
the Effective Time in accordance with this Agreement and all of the shares of
NCC Common Stock issuable upon exercise of the stock options set forth in
Section 2.2 will be, when so issued, duly authorized, validly issued, fully
paid and nonassessable and will not be subject to preemptive rights.
         3.4  SUBSIDIARIES.  The name and state of incorporation of each
significant subsidiary (as defined herein) of NCC (collectively, the
"Significant Subsidiaries") is set forth in the NCC Disclosure Letter.  Each of
the NCC subsidiaries is a bank or a corporation duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
incorporation or organization 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





                                      -9-
<PAGE>   111





such qualification necessary, except for such jurisdictions in which 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,
lease  and operate its properties and assets and to carry on its businesses as
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
paid and (except pursuant to 12 U.S.C. Section 55 in the case of each national
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,
right, convertible security or other similar agreement or commitment.
         3.5  INFORMATION IN DISCLOSURE DOCUMENTS, REGISTRATION STATEMENT, ETC.
None of the information with respect to NCC or any of NCC's subsidiaries
provided by NCC for inclusion in the Registration Statement to be filed with
the Securities and Exchange Commission (the "Commission") by NCC on Form S-4
under the Securities Act of 1933, as amended (the "Securities Act"), for the
purpose of registering the shares of NCC Common Stock to be issued in the
Merger (the "Registration Statement") at the time it becomes effective and in
the proxy statement of the Company required to be mailed to its shareholders
("Company Proxy") at the time of mailing such proxy statement, and any
supplement thereto, will contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading.  NCC shall notify Company on or before the date
of the Company Meeting if any material fact provided by NCC for inclusion in
the Company Proxy is or becomes untrue or misleading or if additional
information needs to be communicated to Company's shareholders so as to make
any statements concerning NCC, in light of circumstances under which they were
made, not misleading.  The Registration Statement will comply as to form in all





                                      -10-
<PAGE>   112





material respects with the provisions of the Securities Act and the rules and
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

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

a consistent basis (except as may be indicated therein or in the notes thereto)
and fairly present the consolidated financial position of NCC and NCC's
subsidiaries as of the dates thereof and the 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 NCC and its consolidated subsidiaries, contingent or
otherwise, except as disclosed in the NCC Reports.  NCC's reserve for possible
loan losses as shown in its Annual Report on Form 10-K for the fiscal year

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
to any such taxes or to any open taxable year or period.  Except as set forth

consented





                                      -12-

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-
<PAGE>   115





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
("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
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

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-

the applicable requirements of ERISA, the Code, and any other applicable laws.

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
amended (and any trust relating thereto) intended to be a qualified plan under
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

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

maintained by any entity considered one employer with it under Section 4001 of

Subtitle E of Title IV of ERISA.  Neither Company nor any Company Subsidiary

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

Subsidiaries which would or insofar as reasonably can be foreseen in the future
will have a Material Adverse Effect.
         4.12 LITIGATION.  Except as set for in the Company Disclosure Letter
or disclosed in Company Reports filed by Company with the Commission prior to
the date of this Agreement, there is no suit, action or proceeding pending, or,
to the knowledge of Company, threatened against or affecting Company or any
Company Subsidiary which, if determined adversely to Company, would be
reasonably expected to have a Material Adverse Effect, nor is there any
judgment, decree, injunction, rule or order of any Governmental Entity or
arbitrator, outstanding against Company or any Company Subsidiary having, or

law, ordinance, regulation, judgment, order, decree, license or permit of any
Governmental Entity (including, without limitation, in the case of Company
Subsidiaries that are savings banks, all statutes, rules and regulations
pertaining to the conduct of the savings bank business), except for violations
which individually or in the aggregate do not, and, insofar as reasonably can
be foreseen, in the future will not, have a Material Adverse Effect.  Except as
set forth in the Company Disclosure Letter, no investigation or review by any
Governmental Entity with respect to Company or any Company Subsidiary is
pending or, to the knowledge of Company, threatened, nor has any Governmental
Entity indicated an intention to conduct the same in each case other than those
the outcome of which will not have a Material Adverse Effect.
         4.14 AGREEMENTS WITH REGULATORS, ETC.  Neither Company nor any Company
Subsidiary is a party to any written agreement or memorandum of understanding
with, or a party to any commitment letter, board resolution or similar
undertaking to, or is subject to any order or directive by, or is a recipient
of any extraordinary supervisory letter from, any Governmental Entity which
restricts materially the conduct of its business, or in any manner relates to
its capital adequacy, its credit or reserve policies or its management, except
for those the existence of which





                                      -25-

has been disclosed in the Company Disclosure Letter, nor has Company been
advised by any Governmental Entity that it is contemplating issuing or
requesting (or is considering the appropriateness of issuing or requesting) any
such order, decree, agreement, memorandum of understanding, extraordinary
supervisory letter, commitment letter or similar submission, except as set
forth in the Company Disclosure Letter.  Except as set forth in the Company

Federal banking agency of a proposed addition of an individual to its board of
directors or the employment of an individual as a senior or executive officer.
         4.15 FEES.  Except for fees paid and payable to McDonald & Company

thereon are the only votes of the holders of any class or series of Company
capital stock necessary to approve the deletion of Article 11 of the Company's
Articles of Incorporation and this Agreement and the transactions contemplated
by the Agreement.
         4.18 MATERIAL INTERESTS OF CERTAIN PERSONS.  Except as disclosed in

forth in the Company Disclosure Letter, no officer or director of Company, or
any "associate" (as such term is defined in Rule 14a-1 under the Exchange Act)
of any such officer or director, has any material interest in any material
contracts or property (real or personal), tangible or intangible, used in or
pertaining to the business of Company or any Company Subsidiaries.

         5.1  ACQUISITION PROPOSALS.  Each of Company and Company Subsidiaries
shall not, directly or indirectly, and shall instruct and otherwise use its
best efforts to cause their respective officers, directors, employees, agents
or advisors or other representatives or consultants not to, directly or
indirectly, (i) solicit or initiate any proposals or offers from any person

extent that the Board is required, in a written opinion of counsel to the
Board, in the exercise of its fiduciary duties in accordance with applicable

opinion of counsel to the Board of Directors of the Company, is otherwise

any such information is requested from, or any such negotiations or discussions
are sought to be initiated or continued with Company.
         5.2  INTERIM OPERATIONS OF COMPANY.  During the period from the date
of this Agreement to the Effective Time, except as specifically contemplated by
this Agreement, set forth in the Company Disclosure Letter or as  otherwise
approved expressly in writing by NCC (which approval will not be unreasonably
withheld):
                 (a)  CONDUCT OF BUSINESS.  Company shall, and shall cause each
of the Company Subsidiaries to, conduct their respective businesses only in,

any change or amendment to its or their respective articles of incorporation or
by-laws (or comparable governing instruments).
                 (c)  CAPITAL STOCK.  Except pursuant to the exercise of stock
options outstanding as of the date hereof under the Company's Option Plans,
Company shall not, and shall not permit





                                      -28-
<PAGE>   130





any Company Subsidiary to, issue or sell any shares of capital stock or any
other securities of any of them or issue any securities convertible into or
exchangeable for, or options, warrants to purchase, scrip, rights to subscribe
for, calls or commitments of any character whatsoever relating to, or enter

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

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

                                      -29-
<PAGE>   131





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>   132





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>   133





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>   134





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>   135





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

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

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>   137





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>   138





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).

                 (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,

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.

<PAGE>   140





                 (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>   141





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

                 (a)  NCC shall have performed in all material respects its

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

the shareholders of the Company from a financial point of view.

                 (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,

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)  Company shall have furnished NCC a Certificate dated the
date of the Closing signed by the President or Chief Executive Officer and
Chief Financial Officer of Company that, to the best of their knowledge and
belief after due inquiry, the conditions set forth in subsections 7.3(a) and
7.3(b) have been satisfied.
                 (d)  NCC and its directors and officers who sign the
Registration Statement shall have received from Crowe, Chizek & Company,
Company's independent certified public accountants, "comfort" letters, dated
(i) the date of the mailing of the Proxy Statement to Company's shareholders

intent of the parties as closely as possible in an acceptable manner to the end
that the transactions contemplated by this Agreement are consummated to the
extent possible.
         IN WITNESS WHEREOF, the parties hereto have caused their duly

                               November   , 1994
 
Board of Directors
Central Indiana Bancorp
200 W. Mulberry Street
Kokomo, IN 46903-0730
 
Gentlemen:
 
     You have requested our opinion with respect to the fairness, from a
financial point of view, as of the date hereof, to the holders of common stock,
no par value ("Central Indiana Common"), of Central Indiana Bancorp, an Indiana
corporation ("Central Indiana"), of the exchange ratio (the "Exchange Ratio")
set forth in Section 2.1(a) of the Agreement and Plan of Merger (the "Merger
Agreement"), dated July 25, 1994, between Central Indiana and National City
Corporation ("NCC"). The Exchange Ratio provides for the exchange of each share
of Central Indiana Common for 1.08 shares of common stock, par value $4.00 per
share ("NCC Common"), of NCC.
 
     The Merger Agreement provides for the merger (the "Merger") of Central
Indiana with and into NCC, pursuant to which, among other things, at the
effective time of the Merger (as defined in the Merger Agreement) outstanding
shares of Central Indiana Common will be converted into the right to receive
shares of NCC Common at the Exchange Ratio. The terms and conditions of the
Merger are more fully set forth in the Merger Agreement.
 
     McDonald & Company Securities, Inc., as part of its investment banking
business, is customarily engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.
 
     We have acted as Central Indiana's financial advisor in connection with,
and have participated in certain of the negotiations leading to, the execution
of the Merger Agreement.
 
     In connection with rendering our opinion set forth herein, we have among
other things:
 
          (i) Reviewed Central Indiana's Annual Reports to Shareholders and
     Annual Reports on Form 10-K for each of the three fiscal years ended
     September 30, 1993, including the audited financial statements contained
     therein, Central Indiana's Quarterly Reports on Form 10-Q for the three 
     month periods ended December 31, 1993, March 31, 1994 and June 30, 1994 
     as well as Central Indiana's audited financial statements for the fiscal 
     year ended September 30, 1994 contained in this Prospectus and Proxy 
     Statement;
 
          (ii) Reviewed NCC's Annual Reports to Shareholders and Annual Reports
     on Form 10-K for each of the three years ended December 31, 1993, as well
     as NCC's Quarterly Reports on Form 10-Q for the three month periods ended
     March 31, 1994, June 30, 1994 and September 30, 1994;
 
          (iii) Reviewed certain other non-public information, primarily
     financial in nature, relating to the respective businesses, earnings,
     assets and prospects of Central Indiana and NCC furnished to us and
     prepared by Central Indiana and NCC;
 
          (iv) Participated in meetings and telephone conferences with members
     of senior management of Central Indiana and meetings and telephone
     conferences with members of senior management of NCC concerning the
     financial condition, business, assets, financial forecasts and prospects of
     the respective companies, as well as other matters we believe relevant to
     our inquiry;
 
          (v) Reviewed certain stock market information for Central Indiana
     Common and NCC Common and compared it with similar information for certain
     companies, the securities of which are publicly traded;
 
          (vi) Compared the results of operations and financial condition of
     Central Indiana with that of certain companies which we deemed to be
     relevant for purposes of this opinion;
 
                                       B-1
<PAGE>   151
 
          (vii) Reviewed the financial terms, to the extent publicly available,
     of certain acquisition transactions which we deemed to be relevant for
     purposes of this opinion;
 
          (viii) Reviewed the Merger Agreement and its schedules and exhibits
     and certain related documents; and
 
          (ix) Performed such other analyses as we have deemed appropriate.
 
     In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information reviewed by us and have relied upon the accuracy and completeness of
the representations and warranties of Central Indiana and NCC contained in the
Merger Agreement without undertaking any responsibility for independent
verification of such matters. We have not conducted a physical inspection of any
of the assets, properties or facilities of either Central Indiana or NCC, nor
have we made or obtained or been furnished with any independent evaluation or
appraisal of any of such assets, properties or facilities or any of the
liabilities of either Central Indiana or NCC. With respect to financial
forecasts provided to us by management of Central Indiana and NCC, we have
assumed that such forecasts have been reasonably prepared on a basis reflecting
the best currently available estimates and judgments of the management of
Central Indiana and NCC as to the future performance of Central Indiana and NCC,
as the case may be. We express no view as to such financial forecasts or the
assumptions on which they are based. We have also assumed that all of the
conditions to the consummation of the Merger, as set forth in the Merger
Agreement, including the tax-free treatment of the Merger to the holders of
Central Indiana Common, would be satisfied and that the Merger would be
consummated on a timely basis in the manner contemplated by the Merger
Agreement.
 
     We will receive a fee for our services as financial advisor to Central
Indiana, a significant portion of which is contingent upon closing of the
Merger.
 
     In the ordinary course of our business, we may actively trade securities of
both Central Indiana and NCC for our own account and for the accounts of
customers and, accordingly, we may at any time hold a long or short position in
such securities.
 
     This opinion is based on economic and market conditions and other
circumstances existing on, and information made available as of, the date
hereof. In addition, our opinion is, in any event, limited to the fairness, as
of the date hereof, from a financial point of view, of the Exchange Ratio and
does not address Central Indiana's underlying business decision to effect the
Merger or any other terms of the Merger and does not constitute a recommendation
to any Central Indiana shareholder as to how such shareholder should vote with
respect to the Merger. We are not rendering any opinion as to what the value of
Central Indiana Common or NCC Common may be at the effective time of the Merger
or the prospects of NCC's business nor are we making any recommendation to
Central Indiana shareholders with respect to the advisability of disposing or
retaining NCC Common received pursuant to the Merger.
 
     This opinion has been prepared solely for the confidential use of the Board
of Directors and senior management of Central Indiana and will not be
reproduced, summarized, described or referred to or given to any other person
without our prior written consent. Notwithstanding the foregoing, this opinion
may be included in a proxy statement to be mailed to the holders of Central
Indiana Common in connection with the Merger, provided that this opinion will be
reproduced in such proxy statement in full, and any description of or reference
to us or our actions, or any summary of the opinion in such proxy statement will
be in a form acceptable to us and our counsel.
 
     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Exchange Ratio pursuant to the Merger Agreement is fair to the
holders of Central Indiana Common from a financial point of view.
 
                                            Very truly yours,
 
                                            MCDONALD & COMPANY SECURITIES, INC.

                             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>   153
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>   154
         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.

<PAGE>   155
                 (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>   156
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>   157
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.

                 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>   159
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>   160
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>   161
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>   162
                          (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>   163
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>   164
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>   165
                 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-
<PAGE>   166
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
communications hereunder shall be deemed to have been duly given when delivered
in person, by cable, telegram, telecopy or telex, or by registered or certified
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
