         Item 5.  Other Events

                   On February 4, 1995, Michigan National Corporation, a
         Michigan Corporation (the "Company"), entered into an Agreement
         and Plan of Merger (the "Merger Agreement") with National
         Australia Bank Limited A.C.N. 004044937, a commercial bank
         organized under Australian law ("NAB"), pursuant to which a
         wholly owned subsidiary of NAB will merge with the Company (the
         "Merger").  As a result of the Merger, the outstanding shares
         of the Company's common stock, par value $10 per share
         ("Company Common Stock"), will be converted into the right to
         receive from the surviving corporation U.S. $110 per share, in
         cash.  The Merger is conditioned upon, among other things,
         approval by holders of a majority of the Company Common Stock
         and upon receipt of certain regulatory and governmental
         approvals.  The Merger Agreement is attached as Exhibit 1
         hereto and its terms are incorporated herein by reference.

                   Simultaneously with their execution and delivery of
         the Merger Agreement, the Company and NAB entered into a Stock
         Option Agreement pursuant to which the Company granted NAB the
         right, upon the terms and subject to the conditions set forth
         therein, to purchase up to 2,633,502 shares of Company Common
         Stock at a price of $89 per share.  The Stock Option Agreement
         is attached as Exhibit 2 hereto and its terms are incorporated
         herein by reference.

                   A copy of the Press Release, dated February 6, 1995,
         issued by the Company and NAB relating to the Merger Agreement
         and the Stock Option Agreement is attached as Exhibit 3 hereto
         and is incorporated herein by reference.

                   On February 4, 1995, the Company amended its Rights
         Agreement, dated as of April 25, 1988, by and between the
         Company and Mellon Bank, N.A. (the "Rights Agreement"), with
         the effect of exempting the Merger, the Merger Agreement, the
         Stock Option Agreement, and the events and the transactions
         contemplated thereby from the Rights Agreement.  The amendments
         to the Rights Agreement are attached hereto as Exhibit 4 and
         are incorporated herein by reference.

                        AGREEMENT AND PLAN OF MERGER dated as of Feb-
                   ruary 4, 1995, among NATIONAL AUSTRALIA BANK LIMITED
                   A.C.N. 004044937, an Australian corporation ("Par-
                   ent"), MNC ACQUISITION CO., a Michigan corporation
                   and a wholly owned subsidiary of Parent ("Sub"), and
                   MICHIGAN NATIONAL CORPORATION, a Michigan corporation
                   (the "Company").


                   WHEREAS the Company is a registered bank holding
         company under the Bank Holding Company Act of 1956, as amended
         (the "BHC Act");

                   WHEREAS Parent is a commercial bank under Australian
         law and is a foreign bank within the meaning of the Interna-
         tional Banking Act of 1978, as amended (the "IBA");

                   WHEREAS the respective Boards of Directors of Parent,
         Sub and the Company have approved the merger of Sub into the
         Company, or the Company into Sub, at the election of Parent as
         set forth below (the "Merger"), upon the terms and subject to
         the conditions set forth in this Agreement, whereby each issued
         and outstanding share of common stock, par value U.S. $10 per
         share, of the Company ("Company Common Stock"), not owned
         directly or indirectly by Parent or the Company, will be con-
         verted into the right to receive U.S. $110.00 in cash;

                   WHEREAS, as a condition and inducement to Parent's
         and Sub's willingness to enter into this Agreement, Parent, Sub
         and the Company are entering into a Stock Option Agreement
         dated as of the date hereof in the form of Exhibit A attached
         hereto (the "Stock Option Agreement") pursuant to which the
         Company has granted to Parent an option to purchase shares of
         Company Common Stock;

                   WHEREAS the Merger requires the approval by an
         affirmative vote of the holders of a majority of the out-
         standing shares of Company Common Stock entitled to vote
         thereon ("Company Stockholder Approval"); and

                   WHEREAS Parent, Sub and the Company desire to make
         certain representations, warranties, covenants and agreements
         in connection with the Merger and also to prescribe various
         conditions to the Merger.


                   NOW, THEREFORE, in consideration of the foregoing and
         the respective representations, warranties, covenants and
         agreements set forth herein and in the Stock Option Agreement,
         the parties hereto agree as follows:<PAGE>







                                    ARTICLE I

                                    The Merger

                   SECTION 1.01.  The Merger.  Upon the terms and sub-
         ject to the conditions set forth in this Agreement, and in
         accordance with the Michigan Business Corporation Act (the
         "MBCA"), Sub shall be merged with and into the Company at the
         Effective Time (as defined in Section 1.03). Following the
         Merger, the separate corporate existence of Sub shall cease and
         the Company shall continue as the surviving corporation (the
         "Surviving Corporation") and shall succeed to and assume all
         the rights and obligations of Sub in accordance with the MBCA.
         Notwithstanding the foregoing, Parent may elect at any time
         prior to the mailing of the Proxy Statement (as defined here-
         in), instead of merging Sub into the Company as provided above,
         to merge the Company with and into Sub; provided, however, that
         the Company shall not be deemed to have breached any of its
         representations, warranties, covenants or agreements set forth
         in this Agreement solely by reason of such election; provided,
         further, that no such election may be made if it would alter or
         change the amount or kind of Merger Consideration (as defined
         in Section 2.01(c)) to be received by holders of Company Common
         Stock pursuant to Article II, or be reasonably likely to
         materially delay or impede consummation of the transactions
         contemplated hereby.  In such event, the parties agree to
         execute an appropriate amendment to this Agreement in order to
         reflect the foregoing and, where appropriate, to provide that
         Sub shall be the Surviving Corporation and shall continue under
         the name "Michigan National Corporation".

                   SECTION 1.02.  Closing.  The closing of the Merger
         (the "Closing") will take place at 10:00 a.m. on a date to be
         specified by the parties, which shall be no later than the
         later of (i) the third business day or (ii) the first business
         day of the month, in either case following the satisfaction (or
         waiver) of all the conditions set forth in Article VI (the
         "Closing Date"), at the offices of Cravath, Swaine & Moore,
         Worldwide Plaza, 825 Eighth Avenue, New York, NY 10019, unless
         another time, date or place is agreed to in writing by the
         parties hereto.

                   SECTION 1.03.  Effective Time.  Subject to the pro-
         visions of this Agreement, as soon as practicable on the
         Closing Date, a certificate of merger or other appropriate
         documents (in any such case, the "Certificate of Merger") shall
         be duly prepared, executed, acknowledged and filed by the
         parties in accordance with the relevant provisions of the MBCA
         with the Department of Commerce of the State of Michigan.  The



                                       -2-<PAGE>







         Merger shall become effective upon the filing of the Certifi-
         cate of Merger with the Department of Commerce of the State of
         Michigan or at such time thereafter as is provided in the
         Certificate of Merger (the time the Merger becomes effective
         being hereinafter referred to as the "Effective Time").

                   SECTION 1.04.  Effects of the Merger.  The Merger
         shall have the effects set forth in Section 724 of the MBCA.

                   SECTION 1.05.  Articles of Incorporation and By-laws.
         (a)  The articles of incorporation of the Company as in effect
         immediately prior to the Effective Time shall be the articles
         of incorporation of the Surviving Corporation until thereafter
         changed or amended as provided therein or by applicable law. 

                   (B)  The by-laws of the Company as in effect imme-
         diately prior to the Effective Time shall be the by-laws of the
         Surviving Corporation, until thereafter changed or amended as
         provided therein or by applicable law.

                   SECTION 1.06.  Directors.  The directors of Sub at
         the Effective Time and the persons listed on Schedule 1.06
         shall be the directors of the Surviving Corporation, until the
         earlier of their resignation or removal or until their
         respective successors are duly elected and qualified, as the
         case may be.

                   SECTION 1.07.  Officers.  The officers of the Company
         immediately prior to the Effective Time shall be the officers
         of the Surviving Corporation, until the earlier of their res-
         ignation or removal or until their respective successors are
         duly elected and qualified, as the case may be.

                   SECTION 1.08.  Principal Place of Business.  Parent
         currently intends to maintain the Surviving Corporation's
         headquarters and its principal place of business at the Com-

                                       -3-<PAGE>







                   (a)  Capital Stock of Sub.  Each issued and out-
              standing share of capital stock of Sub shall be converted
              into and become one fully paid and nonassessable share of
              Common Stock, par value U.S. $.01 per share, of the
              Surviving Corporation.

                   (b)  Cancellation of Company and Parent Owned Stock.
              Each share of Company Common Stock that is owned by the
              Company or by any subsidiary of the Company (which shall
              not include any shares owned by the Company's Employee
              Stock Ownership Plan and Trust (the "ESOP")) and each
              share of Company Common Stock that is owned by Parent, Sub
              or any other subsidiary of Parent (other than, in each
              case, shares in trust accounts, managed accounts, custo-
              dial accounts and the like that are beneficially owned by
              third parties (any such shares, "Trust Account Shares"))
              shall be automatically cancelled and retired and shall
              cease to exist, and no consideration shall be delivered in
              exchange therefor.

                   (c)  Conversion of Company Common Stock.  Each issued
              and outstanding share of Company Common Stock (other than
              shares to be cancelled in accordance with Section 2.01(b))
              shall be converted into the right to receive from the
              Surviving Corporation in cash, without interest, U.S.
              $110.00 (the "Merger Consideration"). As of the Effective
              Time, all such shares of Company Common Stock shall no
              longer be outstanding and shall automatically be cancelled
              and retired and shall cease to exist, and each holder of a
              certificate previously representing any such shares shall
              cease to have any rights with respect thereto, except the
              right to receive the Merger Consideration, without
              interest.

                   SECTION 2.02.  Exchange of Certificates.  (a)  Paying
         Agent.  Prior to the Effective Time, Parent shall designate
         Michigan National Bank, a national banking association and a
         wholly owned subsidiary of the Company ("MNB"), or such other
         bank or trust company reasonably acceptable to the Company, to
         act as paying agent (the "Paying Agent") for the payment of the
         Merger Consideration upon surrender of certificates repre-
         senting Company Common Stock.

                   (b)  Parent To Provide Funds.  Parent shall take all
         steps necessary to enable and cause Sub, or the Surviving
         Corporation, to provide to the Paying Agent on a timely basis,
         as and when needed on and after the Effective Time, funds
         necessary to pay for the shares of Company Common Stock as part
         of the Merger pursuant to Section 2.01.



                                       -4-<PAGE>







                   (c)  Exchange Procedures.  As soon as reasonably
         practicable (and in any event no later than 10 days) after the
         Effective Time, Parent shall cause the Paying Agent to mail to
         each holder of record of a certificate or certificates which
         immediately prior to the Effective Time represented outstanding
         shares of Company Common Stock (the "Certificates") whose
         shares were converted into the right to receive the Merger
         Consideration pursuant to Section 2.01 (i) a letter of trans-
         mittal (which shall specify that delivery shall be effected,
         and risk of loss and title to the Certificates shall pass, only
         upon delivery of the Certificates to the Paying Agent and shall
         be in such form and have such other customary provisions as
         Parent may reasonably specify) and (ii) instructions for use in
         effecting the surrender of the Certificates in exchange for the
         Merger Consideration.  Upon surrender of a Certificate for
         cancellation to the Paying Agent or to such other agent or
         agents as may be appointed by Parent, together with such letter
         of transmittal, duly executed, and such other customary docu-
         ments as may be reasonably required by the Paying Agent, the
         holder of such Certificate shall be entitled to receive in
         exchange therefor the amount of cash into which the shares of
         Company Common Stock theretofore represented by such Certifi-
         cate shall have been converted pursuant to Section 2.01, and
         the Certificate so surrendered shall forthwith be cancelled.
         In the event of a transfer of ownership of Company Common Stock
         which is not registered in the transfer records of the Company,
         payment may be made to a person other than the person in whose
         name the Certificate so surrendered is registered, if such
         Certificate shall be properly endorsed or otherwise be in
         proper form for transfer and the person requesting such payment
         shall pay any transfer or other taxes required by reason of the
         payment to a person other than the registered holder of such
         Certificate or establish to the satisfaction of the Surviving
         Corporation that such tax has been paid or is not applicable.
         Until surrendered as contemplated by this Section 2.02, each
         Certificate shall be deemed at any time after the Effective
         Time to represent only the right to receive upon such surrender
         the amount of cash, without interest, into which the shares of
         Company Common Stock theretofore represented by such Certifi-
         cate shall have been converted pursuant to Section 2.01.  No
         interest will be paid or will accrue on the cash payable upon
         the surrender of any Certificate.

                   (d)  No Further Ownership Rights in Company Common
         Stock.  All cash paid upon the surrender of Certificates in
         accordance with the terms hereof shall be deemed to have been
         paid in full satisfaction of all rights pertaining to the
         shares of Company Common Stock theretofore represented by such
         Certificates, subject, however, to the Surviving Corporation's
         obligation to pay any dividends or make any other distributions


                                       -5-<PAGE>







         with a record date prior to the Effective Time which may have
         been declared or made by the Company on such shares of 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, and there shall be no further registration of
         transfers on the stock transfer books of the Surviving Corpo-
         ration of the shares of Company Common Stock which were out-
         standing immediately prior to the Effective Time.  If, after
         the Effective Time, Certificates are presented to the Surviving
         Corporation for any reason, they shall be cancelled and
         exchanged as provided in this Article II.

                   (e)  No Liability.  None of Parent, Sub, the Company
         or the Paying Agent shall be liable to any person in respect of
         any cash delivered to a public official pursuant to any
         applicable abandoned property, escheat or similar law.  If any
         Certificates shall not have been surrendered prior to seven
         years after the Effective Time (or immediately prior to such
         earlier date on which any payment pursuant to this Article II
         would otherwise escheat to or become the property of any Gov-
         ernmental Entity (as defined in Section 3.01(c))), the cash
         payment in respect of such Certificate shall, to the extent
         permitted by applicable law, become the property of the Sur-
         viving Corporation, free and clear of all claims or interests
         of any person previously entitled thereto.

                                   ARTICLE III

         ness in each jurisdiction in which the nature of its business
         or the ownership or leasing of its properties makes such
         qualification necessary except where the failure so to qualify



                                       -6-<PAGE>







         would not have a Material Adverse Effect (as defined in Section
         8.03(a)) on the Company.

         13(g) of the Exchange Act) that the Company was required to

         dates, the Company SEC Documents complied in all material
         respects with the requirements of the Securities Act of 1933,
         as amended (the "Securities Act"), or the Exchange Act, as the
         case may be, and the rules and regulations of the SEC there-
         under applicable to such Company SEC Documents.  All material
         agreements, contracts and other documents required to be filed
         as exhibits to any of the Company SEC Documents have been so
         filed.  Except to the extent that information contained in any
         Company SEC Document has been revised or superseded by a later
         Company Filed SEC Document (as defined in Section 3.01(f)),
         none of the Company SEC Documents contains any untrue statement
         of a material fact or omits to state a material fact required
         to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were
         made, not misleading.

         respects with applicable accounting requirements and with the

         accepted accounting principles applied on a consistent basis

         cated in the notes thereto or, in the case of the unaudited
         statements, as permitted by Form 10-Q of the SEC) and fairly
         present the consolidated financial position of the Company and
         its consolidated subsidiaries as at the dates thereof and the
         consolidated results of their operations and cash flows for the
         periods then ended.

         its subsidiaries, including MNB, has filed all material
         reports, registrations and statements, together with any
         required material amendments thereto ("Company Regulatory

         OTS, all applicable state banking and other regulatory au-
         thorities and other relevant Governmental Entities charged with
         the supervision or regulation of the Company or any of its
         subsidiaries (collectively, "Regulatory Authorities").  As of
         their respective dates, each such Company Regulatory Report
         complied in all material respects with all the rules and reg-
         ulations promulgated by the applicable Regulatory Authority
         (including regulatory accounting practices) and, except as
         revised or superseded by a later filed Company Regulatory
         Report, does not contain any untrue statement of a material
         fact or omit to state a material fact required to be stated
         therein or necessary in order to make the statements therein,
         in light of the circumstances under which they were made, not
         misleading. The Company has made available to Parent true and
         complete copies of MNB's most recent annual and quarterly
         Consolidated Reports of Condition and Income ("Call Reports")
         filed with the OCC.

         date of mailing to stockholders and at the time of the Company
         Stockholders Meeting, contain any untrue statement of a mate-
         rial fact or omit to state any material fact required to be

         form in all material respects with the provisions of the
         Exchange Act and the rules and regulations thereunder, except
         that no representation or warranty is made by the Company with
         respect to statements made or incorporated by reference therein

         mit, except for the lack of Company Permits and for defaults
         under Company Permits which lack or default individually or in

         ment (the "Company Filed SEC Documents"), the Company and its

         Merger, neither the Company nor any of its subsidiaries is
         required by Section 32 of the FDIA to give prior notice to a

         required to be filed or sent (including in each case exten-
         sions) by or relating to any of them relating to any taxes with
         respect to any income, properties or operations of the Company
         or any such subsidiary prior to the Effective Time (collec-
         tively, "Company Returns"), (B) as of the time of filing, the
         Company Returns correctly reflected in all material respects
         the facts regarding the income, business, assets, operations,
         activities and status of the Company and its subsidiaries and
         any other information required to be shown therein, (C) the

         subsidiaries have made or will make provision for all taxes
         payable for any periods that end before the Effective Time for

         periods that begin before the Effective Time and end after the
         Effective Time to the extent such taxes are attributable to the
         portion of any such period ending at the Effective Time, (E)
         the charges, accruals and reserves for taxes reflected on the
         books of the Company and its subsidiaries are adequate to cover
         the tax liabilities accruing or payable by the Company and its
         subsidiaries in respect of periods prior to the date hereof,
         (F) neither the Company nor any subsidiary is delinquent in the
         payment of any taxes or has requested any extension of time
         within which to file or send any Company Return, which Company
         Return has not since been filed or sent, (G) no deficiency for
         any taxes has been proposed, asserted or assessed in writing
         against the Company or any of its subsidiaries other than those
         taxes being contested in good faith, (H) the Federal income tax
         returns of the Company or any consolidated group to which it
         belongs have been examined by and settled with the United
         States Internal Revenue Service (the "IRS") for all years
         through December 31, 1987, (I) neither the Company nor any
         subsidiary has granted any extension of the limitation period
         applicable to any tax claims (which period has not since
         lapsed), other than those taxes being contested in good faith,
         and (J) neither the Company nor any subsidiary has any con-
         tractual obligations under any tax sharing agreement with any
         corporation which, as of the Effective Time, is not a member of
         a consolidated group of which all of and only the Company and
         its subsidiaries are members.

                  (ii)  Any amount that could be received (whether in
         cash or property or the vesting of property) as a result of any
         of the transactions contemplated by this Agreement by any
         employee, officer or director of the Company or any of its
         affiliates who is a "disqualified individual" (as such term is
         defined in proposed Treasury Regulation Section 1.280G-1) under
         any employment, severance or termination agreement, other
         compensation arrangement or Company Benefit Plan currently in


                                       -15-<PAGE>







         effect would not be characterized as an "excess parachute
         payment" (as such term is defined in Section 280G(b)(1) of the
         Code).

                 (iii)  The disallowance of a deduction under Section
         162(m) of the Code for employee remuneration will not apply to
         any amount paid or payable by the Company or any subsidiary of
         the Company under any contract, plan, program, arrangement or
         understanding.

                  (iv)  For the purpose of this Agreement, the term
         "tax" (including, with correlative meaning, the terms "taxes"
         and "taxable") shall include, except where the context other-
         wise requires, all Federal, state, local and foreign income,
         profits, franchise, gross receipts, payroll, sales, employment,
         use, property, withholding, excise, occupancy and other taxes,
         duties or assessments of any nature whatsoever (including the
         Michigan single business tax), together with all interest,
         penalties and additions imposed with respect to such amounts.

                   (i)  Certain Agreements.  (A)  Except as disclosed in
         the Company Filed SEC Documents, as of the date of this
         Agreement, neither the Company nor any of its subsidiaries is a
         party or subject to, or has amended or waived any rights under,
         any of the following (whether written or oral, express or
         implied):

                   (i)  any agreement, arrangement or commitment not
              made in the ordinary course of business consistent with
              past practice that is material to the Company on a con-
              solidated basis, or any contract, agreement or under-
              standing relating to the sale or disposition by the Com-
              pany or any of its subsidiaries of any significant assets
              or businesses of the Company or any of its subsidiaries;

                  (ii)  any material agreement, indenture, credit
              agreement or other instrument relating to the borrowing of
              money by the Company or any of its subsidiaries (other
              than certificates of deposit and customary bank funding
              instruments) or the guarantee by the Company or any such
              subsidiary of any such obligation;

                 (iii)  any contract containing covenants which limit
              the ability of the Company or any of its subsidiaries to
              compete in any line of business or with any person or
              which involve any restriction of the geographical area in
              which, or method by which, the Company and its subsid-
              iaries may carry on their respective businesses (other
              than as may be required by law or applicable Regulatory
              Authorities); or


                                       -16-<PAGE>







                  (iv)  any other contract or agreement that would be
              required to be disclosed as an exhibit to the Company's
              annual report on Form 10-K and which has not been so
              disclosed.

                        (B)  Neither the Company nor any of its sub-
         sidiaries is in default under any material agreement, commit-
         ment, arrangement, lease, insurance policy or other instrument,
         whether entered into in the ordinary course of business or
         otherwise and whether written or oral, and there has not
         occurred any event that, with the giving of notice or the lapse
         of time or both, would constitute such a default, except in all
         cases where such default would not, individually or in the
         aggregate, have a Material Adverse Effect on the Company.

                   (j)  Absence of Changes in Benefit Plans.  Except as
         disclosed in the Company Filed SEC Documents, since the date of
         the most recent audited financial statements included in the
         Company Filed SEC Documents, there has not been any adoption or
         amendment in any material respect by the Company or any of its
         subsidiaries of any bonus, pension, profit sharing, deferred
         compensation, incentive compensation, stock ownership, stock
         purchase, stock option, phantom stock, retirement, vacation,
         severance, disability, death benefit, hospitalization, medical
         or other plan, arrangement or understanding (whether or not
         legally binding) providing benefits to any current or former
         employee, officer or director of the Company or any of its
         subsidiaries.  Except as disclosed in the Company Filed SEC
         Documents, there exist no employment, consulting, severance,
         termination or indemnification agreements, arrangements or
         understandings between the Company or any of its subsidiaries
         and any current or former employee, officer or director of the
         Company or any of its subsidiaries.

                   (k)  ERISA Compliance.  (i)  The Company Disclosure
         Schedule contains a list and brief description of each
         "employee pension benefit plan" (as defined in Section 3(2) of
         the Employee Retirement Income Security Act of 1974, as amended
         ("ERISA")) (sometimes referred to herein as a "Pension Plan"),
         each "employee welfare benefit plan" (as defined in Section
         3(1) of ERISA) and each stock option, stock purchase, deferred
         compensation plan or arrangement and each other employee fringe
         benefit plan or arrangement maintained, contributed to or
         required to be maintained or contributed to by the Company, any
         of its subsidiaries or any other person or entity that,
         together with the Company, is treated as a single employer
         under Section 414(b), (c), (m) or (o) of the Internal Revenue
         Code of 1986, as amended (the "Code"), (each, a "Commonly
         Controlled Entity"), for the benefit of any current or former



                                       -17-<PAGE>







         employees, officers, agents, directors or independent con-
         tractors of the Company or any of its subsidiaries (collec-
         tively, "Company Benefit Plans").  The Company has delivered or
         made available to Parent true, complete and correct copies of
         (A) each Company Benefit Plan (or, in the case of any unwritten
         Company Benefit Plans, descriptions thereof), (B) the most
         recent annual report on Form 5500 filed with the IRS with
         respect to each Company Benefit Plan (if any such report was
         required) and (C) the most recent summary plan description (or
         similar document) for each Company Benefit Plan for which such
         summary plan description is required or was provided to plan
         participants or beneficiaries.

                  (ii)  Each Company Benefit Plan has been administered
         in all material respects in accordance with its terms.  The
         Company, its subsidiaries and all the Company Benefit Plans are
         all in compliance in all material respects with the applicable
         provisions of ERISA and the Code.  To the best knowledge of the
         Company, there are no investigations, proceedings or other
         claims involving any Company Benefit Plan that could give rise
         to any material liability.

                 (iii)  All Pension Plans intended to be qualified under
         Section 401(a) of the Code have been the subject of determi-
         nation letters from the IRS to the effect that such Pension
         Plans are qualified and exempt from Federal income taxes under
         Sections 401(a) and 501(a), respectively, of the Code, and, to
         the knowledge of the Company, all such letters are valid and
         effective as of the date hereof.

                  (iv)  No Pension Plan, other than any Pension Plan
         that is a "multiemployer plan" (as such term is defined in
         Section 4001(a)(3) of ERISA; collectively, the "Multiemployer
         Pension Plans"), had, as of the respective last annual valua-
         tion date for each such Pension Plan, an "unfunded benefit
         liability" (as such term is defined in Section 4001(a)(18) of
         ERISA), based on actuarial assumptions which have been fur-
         nished to Parent and neither the Company nor any of its sub-
         sidiaries is aware of any facts or circumstances that would
         materially change the funded status of any such Company Benefit
         Plans.  None of the Pension Plans has an "accumulated funding
         deficiency" (as such term is defined in Section 302 of ERISA or
         Section 412 of the Code), and there has been no application for
         a waiver of the minimum funding standards imposed by Section
         412 of the Code with respect to any Company Benefit Plan that
         is a Pension Plan.  No Commonly Controlled Entity has incurred
         any material liability to a Pension Plan (other than for con-
         tributions not yet due) or to the Pension Benefit Guaranty
         Corporation (other than for premiums not yet due).



                                       -18-<PAGE>







                   (v)  There have been no non-exempt "prohibited
         transactions" (as such term is defined in Section 406 of ERISA
         or Section 4975 of the Code) or any other breach of fiduciary
         responsibility with respect to the Company Benefit Plans that
         could subject the Company, any of its subsidiaries or any
         officer of the Company or any of its subsidiaries to tax or
         penalty under ERISA, the Code or other applicable law.  Neither
         any of such Company Benefit Plans nor any of such trusts has
         been terminated, nor has there been any "reportable event" (as
         that term is defined in Section 4043 of ERISA) with respect
         thereto, during the last five years.

                  (vi)  Neither the Company nor any Commonly Controlled
         Entity (A) maintains or contributes to a "multiemployer plan"
         (as defined in Section 4001(a)(3) of ERISA) or has maintained,
         contributed to or had an obligation to maintain or contribute
         to such a plan within the five full plan years of any such plan
         immediately prior to the date hereof, or (B) has incurred any
         liability to the PBGC or a Company Benefit Plan upon the ter-
         mination of or withdrawal from a Company Benefit Plan, which
         liability remains unpaid as of the date hereof.

                 (vii)  With respect to any Company Benefit Plan that is
         an employee welfare benefit plan, (A) no such Company Benefit
         Plan is funded through a "welfare benefit fund", as such term
         is defined in Section 419(e) of the Code, (B) each such Company
         Benefit Plan that is a "group health plan", as such term is
         defined in Section 5000(b)(1) of the Code, complies in all
         material respects with the applicable requirements of Section
         4980B(f) of the Code and (C) each such Company Benefit Plan
         (including any such Plan covering retirees or other former
         employees) may be amended or terminated without material
         liability to the Company or any of its subsidiaries on or at
         any time after the consummation of the Merger.

                (viii)  No employee of the Company or any subsidiary of
         the Company will be entitled to any additional benefits or any
         acceleration of the time of payment or vesting of any benefits
         under any Company Benefit Plan as a result of the transactions
         contemplated by this Agreement or by the Stock Option Agree-
         ment.

                   (l)  Subsidiaries.  The Company Disclosure Schedule
         sets forth all the subsidiaries of the Company as of the date
         of this Agreement and indicates for each such subsidiary as of
         such date the jurisdiction of incorporation.  Each of the
         Company's subsidiaries that is a bank (as defined in the BHC
         Act) is an "insured bank" as defined in the FDIA and applicable
         regulations thereunder.  Except as provided in Section 55 of
         the National Bank Act in the case of subsidiaries that are


                                       -19-<PAGE>







         national banks, all the shares of capital stock of each of the
         subsidiaries of the Company are fully paid and nonassessable
         and (except for directors' qualifying shares, if any) are owned
         by the Company or another subsidiary of the Company free and
         clear of all Liens.  Except for the capital stock of its sub-
         sidiaries, the Company does not own, directly or indirectly,
         any capital stock or other ownership interest in any corpora-
         tion, bank, partnership, joint venture or other entity.

                   (m)  Absence of Certain Changes or Events.  Except as
         disclosed in the Company Filed SEC Documents, since December
         31, 1993, the Company and its subsidiaries have conducted their
         businesses only in the ordinary course of business consistent
         with past practice and have not incurred any material liabil-
         ity, except in the ordinary course of their business consistent
         with their past practices, nor has there been any change, or
         any event involving a prospective change, in the business,
         assets, financial condition or results of operations of the
         Company or any of its subsidiaries, which in any such case has
         had, or is reasonably likely to have, a Material Adverse Effect
         on the Company.

                   (n)  Article SEVENTH of the Charter; State Takeover
         Statutes.  The Board of Directors of the Company has approved
         the Merger, this Agreement and the Stock Option Agreement and/
         or has taken such other action, and such approval and/or action
         is sufficient, to render inapplicable to the Merger, this
         Agreement, the Stock Option Agreement and the transactions
         contemplated by this Agreement and the Stock Option Agreement
         the provisions of Article SEVENTH of the Company's articles of
         incorporation and the provisions of Chapters 7A and 7B of the
         MBCA.  To the best of the Company's knowledge, no other state
         takeover statute or similar statute or regulation applies or
         purports to apply to the Merger, this Agreement, the Stock
         Option Agreement and the transactions contemplated by this
         Agreement and the Stock Option Agreement.

                   (o)  Vote Required.  The Company Stockholder Approval
         is the only vote of the holders of any class or series of the
         Company capital stock necessary to approve this Agreement and
         the transactions contemplated hereby (assuming for purposes of
         this representation the accuracy of the representations con-
         tained in Section 3.02(d)).

                   (p)  Rights Agreement.  The Company and the Board of
         Directors of the Company have taken all necessary action to (i)
         render the Rights Agreement inapplicable with respect to the
         Merger and the other transactions contemplated by this Agree-
         ment and the Stock Option Agreement and (ii) ensure that (1)



                                       -20-<PAGE>







         neither Parent nor Sub nor any of their affiliates is consid-
         ered to be an "Acquiring Person" or an "Adverse Person" (as
         such terms are defined in the Rights Agreement) and (2) no
         "Stock Acquisition Date" or "Distribution Date" (as such terms
         are defined in the Rights Agreement) occurs by reason of
         announcement, approval, execution or delivery of this Agreement
         or the Stock Option Agreement or the consummation of the
         transactions contemplated hereby and thereby.

                   (q)  Properties.  Except as disclosed in the Company
         Filed SEC Documents, the Company and its subsidiaries (i) have
         good, clear and marketable title to all the properties and
         assets which are material to the Company's business on a con-
         solidated basis and are reflected in the latest audited
         statement of condition included in the Company Filed SEC
         Documents as being owned by the Company and its subsidiaries or
         acquired after the date thereof (except properties sold or
         otherwise disposed of since the date thereof), free and clear
         of all Liens except (A) statutory Liens securing payments not
         yet due, (B) Liens on assets of subsidiaries of the Company
         incurred in the ordinary course of their business and (C) such
         imperfections or irregularities of title or Liens as do not
         affect the use of the properties or assets subject thereto or
         affected thereby or otherwise materially impair business
         operations at such properties, in either case in such a manner
         as to have a Material Adverse Effect on the Company, and (ii)
         are collectively the lessee of all leasehold estates which are
         material to the Company's business on a consolidated basis and
         are reflected in the latest audited financial statements
         included in the Company Filed SEC Documents or acquired after
         the date thereof (except for leases that have expired by their
         terms or as to which the Company has agreed to terminate or
         convey since the date thereof) and is in possession of the
         properties purported to be leased thereunder, and each such
         lease is valid without default thereunder by the lessee or, to
         the Company's knowledge, the lessor, other than defaults that
         would not have a Material Adverse Effect on the Company.  Each
         of the Company and each of its subsidiaries enjoys peaceful and
         undisturbed possession under all such leases.  Substantially
         all the Company's and its subsidiaries' owned buildings,
         structures and equipment have been well maintained and are in
         good and serviceable condition, normal wear and tear excepted.

                   (r)  Insurance.  The Company and its subsidiaries are
         presently insured, and during each of the last five years have
         been insured, for reasonable amounts against such risks as
         companies engaged in similar businesses would, in accordance
         with good business practice, customarily be insured.  The
         Company Disclosure Schedule sets forth a true and complete list
         and brief description of all insurance policies maintained by


                                       -21-<PAGE>







         or for the benefit of the Company, its subsidiaries or their
         directors, officers, employees or agents.

                   (s)  Labor Matters.  No work stoppage involving the
         Company or any of its subsidiaries is pending or, to the best
         knowledge of the Company or its subsidiaries, threatened.
         Neither the Company nor any of its subsidiaries is involved in,
         or to the best knowledge of the Company or its subsidiaries,
         threatened with or affected by any labor dispute, arbitration,
         lawsuit or administrative proceeding which could reasonably be
         expected to have, individually or in the aggregate, a Material
         Adverse Effect on the Company.  Employees of the Company or of

                   SECTION 3.02.  Representations and Warranties of
         Parent and Sub.  Parent and Sub represent and warrant to the
         Company as follows:

                   (a)  Organization and Authority.  Each of Parent and
         Sub is a bank or corporation duly organized, validly existing
         and in good standing under the laws of the jurisdiction in
         which it is incorporated or organized and has the requisite
         power and authority to own, lease and operate its properties
         and to carry on its business as now being conducted.  Each of
         Parent and Sub and each of Parent's other subsidiaries is duly
         qualified and in good standing to do business in each juris-
         diction in which the nature of its business or the ownership or
         leasing of its properties makes such qualification necessary
         except where the failure so to qualify would not have a Mate-
         rial Adverse Effect on Parent.  Sub is a direct or indirect
         wholly owned (other than any directors' qualifying shares)
         subsidiary of Parent.

                   (a)  Authorization.  (i)  Parent and Sub have all
         requisite corporate power and authority to enter into this
         Agreement and the Stock Option Agreement and to consummate the
         transactions contemplated hereby and thereby.  The execution
         and delivery of this Agreement and the Stock Option Agreement
         and the consummation of the transactions contemplated hereby
         and thereby have been duly authorized by all necessary corpo-
         rate action on the part of Parent and Sub.  This Agreement and
         the Stock Option Agreement have been duly executed and deliv-
         ered by Parent and Sub and each constitutes a valid and binding
         obligation of Parent and Sub, enforceable against Parent and
         Sub in accordance with its terms.

                  (ii)  The execution and delivery of this Agreement and
         the Stock Option Agreement do not, and the consummation of the
         transactions contemplated hereby and thereby will not, and


                                       -23-<PAGE>

         or thereof will not, (A) result in any Violation pursuant to
         any provision of the articles of incorporation (or similar
         constitutive document) or by-laws of Parent, Sub or any other
         subsidiary of Parent or (B) subject to obtaining or making the
         consents, approvals, orders, authorizations, registrations,
         declarations and filings referred to in paragraph (iii) below,

         regulation applicable to Parent, Sub or any other subsidiary of
         Parent or their respective properties or assets which Violation
         under this clause (B) could reasonably be expected to have,
         individually or in the aggregate with other such Violations, a
         Material Adverse Effect on Parent.

                 (iii)  No consent, approval, order or authorization of,
         or registration, declaration or filing with, any Governmental
         Entity is required by or with respect to Parent, Sub or any
         other subsidiary of Parent in connection with the execution and
         delivery of this Agreement and the Stock Option Agreement by
         Parent and Sub, or the consummation by Parent and Sub of the
         transactions contemplated hereby and thereby, the failure to
         obtain which could, individually or in the aggregate, reason-
         ably be expected to have a Material Adverse Effect on Parent,

         rial 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 were

         therein based on information supplied by the Company specifi-
         cally for inclusion or incorporation by reference therein.

                   (d)  Ownership of Company Common Stock.  Other than
         pursuant to the Stock Option Agreement, as of the date hereof,
         neither Parent nor any of its affiliates (as such term is

         consummation of the Merger, nor is there any judgment, decree,

              becoming untrue, any of such representations and warran-
              ties that are not so qualified being or becoming untrue in
              any material respect, any of the conditions to the Merger
              set forth in Article VI not being satisfied or a material
              Violation of any provision of the Stock Option Agreement,
              or (unless such action is required by applicable law or
              sound banking practice) which could reasonably be expected
              to adversely affect or delay the ability of any of Parent,
              Sub or the Company or their subsidiaries to obtain any of
              the Requisite Regulatory Approvals (as defined in Section
              6.01(b)) without imposition of a condition or restriction
              of the type referred to in Section 6.02(c).

                   (i)  Advice of Changes; Government Filings.  The
              Company shall confer on a regular and frequent basis with
              Parent, report on operational matters and promptly advise
              Parent orally and in writing of any change or event hav-
              ing, or which, insofar as can reasonably be foreseen,
              could have, individually or in the aggregate a Material
              Adverse Effect on the Company or which would cause or
              constitute a material breach of any of the representa-
              tions, warranties or covenants of the Company contained
              herein.  The Company shall file all reports required to be
              filed by it with the SEC or Nasdaq between the date of
              this Agreement and the Effective Time and shall deliver to
              Parent copies of all such reports promptly after the same
              are filed.  The Company and each subsidiary of the Company
              that is a bank shall file all Call Reports with the
              appropriate Regulatory Authorities and all other reports,
              applications and other documents required to be filed with
              the Federal Reserve and the other Regulatory Authorities
              between the date hereof and the Effective Time and shall
              make available to Parent copies of all such reports
              promptly after the same are filed.  Except where prohib-
              ited by applicable statutes and regulations, the Company


                                       -29-<PAGE>







              shall promptly provide Parent (or its counsel) with copies
              of all other filings made by the Company with any state or
              Federal Governmental Entity in connection with this
              Agreement, the Stock Option Agreement or the transactions
              contemplated hereby or thereby.

                   (j)  Accounting Methods.  Except as contemplated by
              Section 5.09, the Company shall not change its fiscal year
              or its methods of accounting in effect at January 1, 1994,
              except as required by changes in GAAP or regulatory
              accounting practices as concurred in by the Company's
              independent auditors.

                   (k)  Compensation; Benefit Plans.  Neither the Com-
              pany nor any of its subsidiaries will (i) enter into,
              adopt, amend or terminate any Company Benefit Plan or any
              other employee benefit plan or any agreement, arrangement,
              plan or policy between such party and one or more of its
              directors or officers, in each case so as to increase
              benefits thereunder, (ii) increase in any manner the
              compensation or fringe benefits of any of its directors,
              officers or employees or provide any other benefit not
              required by any plan and arrangement as in effect as of
              the date hereof (including the granting of stock options,
              stock appreciation rights, restricted stock, restricted
              stock units or performance units or shares), except for
              normal salary compensation increases, benefit changes or
              cash bonus payments in the ordinary course of business
              consistent with past practice, and, in the case of those
              executive officers referred to in Section 4.01(k) of the
              Company Disclosure Schedule, as set forth therein, (iii)
              create or amend any Company Stock Plan or grant any equity
              based award pursuant to any Company Stock Plan or other-
              wise or (iv) enter into or renew any contract, agreement,
              commitment or arrangement providing for the payment to any
              director, officer or employee of such party of compensa-
              tion or benefits contingent, or the terms of which are
              materially altered, upon the occurrence of any of the
              transactions contemplated by this Agreement or the Stock
              Option Agreement; provided, however, that the Company
              shall, at the request of Parent, use its reasonable
              efforts to enter into employment agreements, in form and
              substance satisfactory to Parent, with those executive
              officers of the Company designated by Parent, which
              employment agreements shall be effective on and after (and
              subject to the occurrence of) the Effective Time and shall
              be assumed by the Surviving Corporation.

                   (l)  Tax Matters.  From the date hereof until the
              Effective Time, (i) the Company and its subsidiaries will


                                       -30-<PAGE>







              file all Company Returns required to be filed with any
              taxing authority in accordance with all applicable laws,
              (ii) the Company and its subsidiaries will timely pay all
              taxes shown as due and payable on the respective Company
              Returns that are so filed and as of the time of filing,
              the Company Returns will correctly reflect the facts
              regarding the income, business, assets, operations,
              activities and the status of the Company and its subsid-
              iaries in all material respects, and (iii) the Company and
              its subsidiaries will promptly notify Parent of any
              action, suit, proceeding, investigation, audit or claim
              pending against or with respect to the Company or any
              subsidiary in respect of any tax where there is a rea-
              sonable possibility of a determination or decision which
              would reasonably be expected to have a significant adverse
              effect on the Company's tax liabilities or other tax
              attributes.  The Company shall not, nor shall it permit
              any of its subsidiaries to, make any tax election or
              settle or compromise any income tax liability.

                   (m)  Settlements, etc.  The Company shall not, nor
              shall it permit any of its subsidiaries to, pay, dis-
              charge, settle or satisfy any claims, liabilities or
              obligations (absolute, accrued, asserted or unasserted,
              contingent or otherwise), other than the payment, dis-
              charge, settlement or satisfaction, in the ordinary course
              of business consistent with sound banking practice or in
              accordance with their terms, of liabilities reflected or
              reserved against in, or contemplated by, the most recent
              consolidated financial statements (or the notes thereto)
              of the Company included in the Company Filed SEC Documents
              or incurred since the date of such financial statements in
              the ordinary course of business consistent with sound
              banking practice.

                   (n)  Material Contracts.  Except in the ordinary
              course of business consistent with sound banking practice,
              the Company shall not, nor shall it permit any of its
              subsidiaries to, modify, amend or terminate any material
              contract, lease or agreement to which the Company or any
              subsidiary is a party or waive, release or assign any
              material rights or claims thereunder. Without limiting the
              generality of the foregoing, without the prior written
              consent of Parent, the Company shall not waive any
              standstill provision contained in any confidentiality
              agreement in existence as of the date hereof between the
              Company and any other person.  Without the prior written
              consent of Parent (which shall not be unreasonably with-
              held), the Company shall not, nor shall it permit any of
              its subsidiaries to, enter into any contract, agreement or


                                       -31-<PAGE>







              arrangement which, if entered into prior to the date
              hereof, would have been covered by clause (i), (ii), (iii)
              or (iv) of Section 3.01(i)(A).

                   (o)  General.  The Company shall not, nor shall it
              permit any of its subsidiaries to, authorize any of, or
              commit or agree to take any of, the foregoing actions
              described in this Section 4.01.

                   SECTION 4.02.  No Solicitation.  (a)  The Company
         shall not, nor shall it permit any of its subsidiaries to, nor
         shall it authorize or permit any officer, director or employee
         of or any investment banker, attorney or other advisor or
         representative of, the Company or any of its subsidiaries to,
         (i) solicit, initiate or encourage the submission of any
         takeover proposal or (ii) participate in any discussions or
         negotiations regarding, or furnish to any person any informa-
         tion with respect to, or take any other action to facilitate
         any inquiries or the making of any proposal that constitutes,
         or may reasonably be expected to lead to, any takeover pro-
         posal; provided, however, that prior to receipt of the Company
         Stockholder Approval, to the extent required by the fiduciary
         obligations of the Board of Directors of the Company, as
         determined in good faith by the Board of Directors based on the
         advice of independent counsel, the Company may, (A) in response
         to an unsolicited takeover proposal and subject to compliance
         with Section 4.02(c), furnish information with respect to the
         Company and its subsidiaries to any person pursuant to a cus-
         tomary confidentiality agreement (as determined by the Com-
         pany's independent counsel) and discuss such information (but
         not the terms of any possible takeover proposal) with such
         person and (B) upon receipt by the Company of an unsolicited
         takeover proposal and subject to compliance with Section
         4.02(c), participate in negotiations regarding such takeover
         proposal.  Without limiting the foregoing, it is understood
         that any violation of the restrictions set forth in the pre-
         ceding sentence by any executive officer of the Company or any
         of its subsidiaries or any investment banker, attorney or other
         advisor or representative of the Company or any of its sub-
         sidiaries, whether or not such person is purporting to act on
         behalf of the Company or any of its subsidiaries or otherwise,
         shall be deemed to be a breach of this Section 4.02(a) by the
         Company.  For purposes of this Agreement, "takeover proposal"
         means any inquiry, proposal or offer from any person relating
         to any direct or indirect acquisition or purchase of a sub-
         stantial amount of the assets of the Company or any of its
         subsidiaries, other than the transactions contemplated by this
         Agreement and the Stock Option Agreement, or of 20% or more of
         any class of equity securities of the Company or any of its
         subsidiaries or any tender offer or exchange offer that if


                                       -32-<PAGE>







         consummated would result in any person beneficially owning 20%
         or more of any class of equity securities of the Company or any
         of its subsidiaries, or any merger, consolidation, business
         combination, sale of substantially all assets, recapitaliza-
         tion, liquidation, dissolution or similar transaction involving
         the Company or any of its subsidiaries other than the trans-
         actions contemplated by this Agreement and the Stock Option
         Agreement.

                   (b)  Except as set forth herein, neither the Board of
         Directors of the Company nor any committee thereof shall (i)
         withdraw or modify, or propose to withdraw or modify, in a
         manner adverse to Parent or Sub, the approval or recommendation
         by such Board of Directors or any such committee of this
         Agreement or the Merger, (ii) approve or recommend, or propose
         to approve or recommend, any takeover proposal or (iii) enter
         into any agreement with respect to any takeover proposal.
         Notwithstanding the foregoing, prior to the receipt of the
         Company Stockholder Approval, the Board of Directors of the
         Company, to the extent required by its fiduciary obligations,
         as determined in good faith by the Board of Directors based on
         the advice of independent counsel, may (subject to the fol-
         lowing sentences) withdraw or modify its approval or recom-
         mendation of this Agreement or the Merger, approve or recommend
         any superior proposal (as defined below), enter into an
         agreement with respect to such superior proposal or terminate
         this Agreement, in each case at any time after the second
         business day following Parent's receipt of written notice
         advising Parent that the Board of Directors has received a
         superior proposal, specifying the material terms and conditions
         of such superior proposal and identifying the person making
         such superior proposal (it being understood that any amendment
         to a superior proposal shall necessitate an additional two
         business day period).  In addition, if the Company proposes to
         enter into an agreement with respect to any takeover proposal,
         it shall concurrently with entering into such agreement pay, or
         cause to be paid, to Parent the Expenses and the Termination
         Fee (each as defined in Section 5.07(b)) in accordance with the
         provisions of Section 5.07(b).  For purposes of this Agreement,
         "superior proposal" means any bona fide takeover proposal made
         by a third party to acquire, directly or indirectly, for con-
         sideration consisting of cash and/or securities, more than 50%
         of the shares of Company Common Stock then outstanding or all
         or substantially all the assets of the Company and otherwise on
         terms which the Board of Directors of the Company determines in
         its good faith judgment (based on the advice of a financial
         advisor of nationally recognized reputation) to be more
         favorable to the Company's stockholders than the Merger and for
         which financing, to the extent required, is then committed or



                                       -33-<PAGE>







         which, in the good faith judgment of such Board of Directors,
         is reasonably capable of being financed by such third party.

                   (c)  In addition to the obligations of the Company
         set forth in paragraph (b) above, the Company promptly shall
         advise Parent orally and in writing of any request for infor-
         mation or of any takeover proposal, or any inquiry with respect
         to or which could lead to any takeover proposal, the material
         terms and conditions of such request, takeover proposal or
         inquiry and the identity of the person making any such request,
         takeover proposal or inquiry.  The Company will keep Parent
         fully informed of the status and details (including amendments
         or proposed amendments) of any such request, takeover proposal
         or inquiry.

                   (d)  Nothing contained in this Section 4.02 shall
         prohibit the Company from taking and disclosing to its stock-
         holders a position contemplated by Rule 14e-2(a) promulgated
         under the Exchange Act or from making any disclosure to the
         Company's stockholders if, in the good faith judgment of the
         Board of Directors of the Company based on the recommendation
         of independent counsel, failure to do so would be inconsistent
         with applicable laws; provided that the Company does not,
         except as permitted by Section 4.02(b), withdraw or modify, or
         propose to withdraw or modify, its position with respect to the
         Merger or approve or recommend, or propose to approve or rec-
         ommend, a takeover proposal.

                              Additional Agreements

                   SECTION 5.01.  Preparation of the Proxy Statement.
         The Company will, as soon as practicable following the date of
         this Agreement, prepare and file a preliminary Proxy Statement
         with the SEC and will use all reasonable efforts to respond to
         any comments of the SEC or its staff and to cause the Proxy
         Statement to be mailed to the Company's stockholders as
         promptly as practicable after responding to all such comments
         to the satisfaction of the SEC or its staff.  The Company will
         notify Parent promptly of the receipt of any comments from the
         SEC or its staff and of any request by the SEC or its staff for
         amendments or supplements to the Proxy Statement or for addi-
         tional information and will supply Parent with copies of all
         correspondence between the Company or any of its representa-
         tives, on the one hand, and the SEC or its staff, on the other
         hand, with respect to the Proxy Statement or the Merger.  If at
         any time prior to the Company Stockholders Meeting there shall
         occur any event that should be set forth in an amendment or



                                       -34-<PAGE>







         supplement to the Proxy Statement, the Company will promptly
         prepare and mail to its stockholders such an amendment or
         supplement.  The Company will not mail any Proxy Statement, or
         any amendment or supplement thereto, to which Parent reasonably
         objects.

                   SECTION 5.02.  Access to Information.  The Company
         shall, and shall cause each of its subsidiaries to, afford to
         Parent and to the officers, employees, accountants, counsel and
         other representatives of Parent, reasonable access, during
         normal business hours during the period prior to the Effective
         Time, to all their respective properties, books, contracts,
         commitments, personnel and records and, during such period, the
         Company shall, and shall cause each of its subsidiaries to,
         furnish promptly to Parent (a) a copy of each report, schedule,
         registration statement and other document filed or received by
         it during such period pursuant to the requirements of Federal
         or state securities laws or Federal or state banking laws
         (other than reports or documents which the Company or subsid-
         iary is not permitted to disclose under applicable law) and (b)
         all other information concerning its business, properties and
         personnel as Parent may reasonably request.  Parent will, and
         will cause its advisors and representatives to, hold any such
         information which is nonpublic in confidence to the extent
         required by, and in accordance with, the terms of the Confi-
         dentiality Agreement dated as of January 11, 1995, between the
         Company and Parent (the "Confidentiality Agreement").  No
         investigation by either Parent or Sub shall affect the repre-
         sentations and warranties of the Company, and each such rep-
         resentation and warranty shall survive such investigation.
         During the period from the date of this Agreement to the
         Effective Time, the Company shall promptly furnish to Parent
         copies of all monthly and quarterly interim financial state-
         ments (including any budgets and variances from budgets) as the
         same become available and shall cause one or more of its des-
         ignated representatives to confer on a regular and frequent
         basis with Parent.  The Company shall promptly notify Parent of
         any material change in its business or operations and of any
         complaints, investigations or hearings (or communications
         indicating that the same may be contemplated) by any Govern-
         mental Entity, or the institution of the threat of material
         litigation involving the Company or its subsidiaries, and shall
         keep Parent fully informed of all such events.

                   SECTION 5.03.  Company Stockholders Meeting.  The
         Company shall duly call, give notice of, convene and hold the
         Company Stockholders Meeting for the purpose of obtaining the
         Company Stockholder Approval as soon as practicable after the
         date on which the definitive Proxy Statement has been mailed to
         the Company's stockholders.  Subject to Section 4.02, the


                                       -35-<PAGE>







         Company will, through its Board of Directors, recommend to its
         stockholders that they grant the Company Stockholder Approval.
         Without limiting the generality of the foregoing, the Company
         agrees that, subject to its right to terminate this Agreement
         pursuant to Section 7.01(d), its obligations pursuant to the
         first sentence of this Section 5.03 shall not be affected by
         (a) the commencement, public proposal, public disclosure or
         communication to the Company of any takeover proposal or (b)
         the withdrawal or modification by the Board of Directors of the
         Company of its approval or recommendation of this Agreement or
         the Merger in accordance with Section 4.02(b).

                   SECTION 5.04.  Legal Conditions to Merger.  Subject
         to the terms and conditions of this Agreement, each of the
         Company and Parent shall, and shall cause its subsidiaries to,
         use all reasonable efforts to take, or cause to be taken, all
         actions, and to do, or cause to be done, and to assist and
         cooperate with the other parties in doing, all things neces-
         sary, proper or advisable to consummate and make effective, in
         the most expeditious manner practicable, the Merger and the
         other transactions contemplated by this Agreement, including
         (a) the obtaining of any necessary consent, authorization,
         order or approval of, or any exemption by, any Governmental
         Entity and/or any other public or private third party which is
         required to be obtained by such party or any of its subsid-
         iaries in connection with the Merger and the other transactions
         contemplated by this Agreement and the Stock Option Agreement
         (including the redemption of the Company Debentures and the
         cancellation of the Equity Contracts in accordance with Section
         5.11), and the making or obtaining of all necessary filings and
         registrations with respect thereto, (b) the defending of any
         lawsuits or other legal proceedings, whether judicial, admin-
         istrative or regulatory, challenging this Agreement or the
         Stock Option Agreement, including seeking to have any stay or
         temporary restraining order entered by any court or other
         Governmental Entity vacated or reversed, and (c) the execution
         and delivery of any additional instruments necessary to con-
         summate the transactions contemplated by, and to fully carry
         out the purposes of, this Agreement and the Stock Option
         Agreement; provided, however, that a party shall not be obli-
         gated to take any action pursuant to the foregoing if the
         taking of such action or such compliance or the obtaining of
         such consent, authorization, order, approval or exemption
         would, in such party's reasonable opinion, (A) be materially
         burdensome to such party and its subsidiaries taken as a whole
         in the context of the transactions contemplated by this
         Agreement or impact in such a materially adverse manner the
         economic or business benefits of the transactions contemplated
         by this Agreement as to render inadvisable the consummation of
         the Merger or (B) result in the imposition of a condition or


                                       -36-<PAGE>







         restriction on such party or on the Surviving Corporation of
         the type referred to in Section 6.02(c).  Each of the Company
         and Parent will promptly cooperate with and furnish information
         to the other in connection with any such burden suffered by, or
         requirement imposed upon, any of them or any of their subsid-
         iaries in connection with the foregoing.  In connection with
         and without limiting the foregoing, the Company and its Board
         of Directors shall (x) take all action necessary to ensure that
         neither Article SEVENTH of the Company's articles of incorpo-
         ration nor any state takeover statute or similar statute or
         regulation (including Chapters 7A and 7B of the MBCA) is or
         becomes applicable to the Merger, this Agreement, the Stock
         Option Agreement or any of the other transactions contemplated
         by this Agreement or the Stock Option Agreement and (y) if
         Article SEVENTH or any state takeover statute or similar
         statute or regulation becomes applicable to the Merger, this
         Agreement, the Stock Option Agreement or any of the other
         transactions contemplated by this Agreement or the Stock Option
         Agreement, take all action necessary to ensure that the Merger
         and the other transactions contemplated by this Agreement and
         the Stock Option Agreement may be consummated as promptly as
         practicable on the terms contemplated by this Agreement and
         otherwise to minimize the effect of such Article, statute or
         regulation on the Merger, this Agreement, the Stock Option
         Agreement or any of the other transactions contemplated by this
         Agreement or the Stock Option Agreement.  Notwithstanding the
         foregoing, the Board of Directors of the Company shall not be
         prohibited from taking any action permitted by the terms of
         this Agreement.

                   SECTION 5.05.  Employee Benefit Plans.  (a)  Except
         as provided in Section 5.06, Parent shall cause the Surviving
         Corporation and its subsidiaries to maintain for a period of at
         least one year after the Effective Time the Company Benefit
         Plans in effect on the date of this Agreement or to provide,
         pursuant to benefit plans of the Surviving Corporation or of
         Parent, benefits to employees of the Surviving Company and its
         subsidiaries that are at least generally comparable in the
         aggregate to those benefits provided under the Company Benefit
         Plans in effect on the date of this Agreement.

                   (b)  Parent shall cause the Surviving Corporation to
         honor in accordance with their terms the employment, severance
         and supplemental pension contracts to which employees of the
         Company are a party that are set forth on the Company Disclo-
         sure Schedule, and honor all provisions for vested benefits and
         other vested amounts earned or accrued through the Effective
         Time under the Company Benefit Plans.

                   SECTION 5.06.  Stock Options and the ESOP.  (a)  As
         soon as practicable following the date of this Agreement, the
         Board of Directors of the Company (or, if appropriate, any
         committee administering the Company Stock Plans) shall adopt
         such resolutions or take such other actions as are required to
         provide for the cancellation of all outstanding employee stock
         options to purchase shares of Company Common Stock ("Company
         Stock Options") heretofore granted under the Company Stock
         Plans to provide that each Company Stock Option, whether vested
         or not, outstanding immediately prior to the Effective Time, in
         exchange for a cash payment by the Company of an amount equal
         to (i) the excess, if any, of (x) the Merger Consideration per
         share over (y) the exercise price per share of Company Common
         Stock subject to such Company Stock Option, multiplied by (ii)
         the number of shares of Company Common Stock subject to such
         Company Stock Options for which such Company Stock Option shall
         not theretofore have been exercised.  The Company shall use its
         best efforts to obtain all consents of the holders of the
         Company Stock Options as shall be necessary to effectuate the
         foregoing.  Notwithstanding anything to the contrary contained
         in this Agreement, payment shall, at Parent's request, be
         withheld in respect of any Company Stock Option until all
         necessary consents with respect to such Company Stock Options
         are obtained.

                   (b)  All amounts payable pursuant to this Section
         5.06 shall be subject to any required withholding of taxes and
         shall be paid without interest.

                   (c)  The Board of Directors of the Company (or, if
         appropriate, any committee administering the Company Stock
         Plans) shall adopt such resolutions or take such actions as are
         required to terminate the Company Stock Plans other than the
         ESOP as of the Effective Time, to delete as of the Effective
         Time the provision in any other Company Benefit Plan providing
         for the issuance, transfer or grant of any capital stock of the
         Company or any interest in respect of any capital stock of the
         Company and to ensure that following the Effective Time no
         holder of a Company Stock Option or any participant in any
         Company Stock Plan or other Company Benefit Plan shall have any
         right thereunder to acquire any capital stock of the Company or
         the Surviving Corporation.

                   (d)  If Parent so requests, the Board of Directors of
         the Company (or, if appropriate, any committee administering
         the ESOP) shall give due consideration to any request by Parent
         to cause the ESOP to continue following the Effective Time, and
         shall give due consideration to any request by Parent to take,
         in accordance with the terms of the ESOP and pursuant to the
         Michigan National Corporation Employee Stock Ownership Trust


                                       -38-<PAGE>







         Agreement (the "Trust Agreement"), such actions as are neces-
         sary (including amendment of the ESOP and the Trust Agreement)
         to cause the trustee thereunder to reinvest the Merger Con-
         sideration in common stock of the Parent (or any equivalent
         equity security) designated by Parent that constitutes, if any,
         a "qualifying employer security" (as defined in Section
         4975(e)(8) and Section 409(l) of the Code).

                   SECTION 5.07.  Fees and Expenses.  (a)  Whether or
         not the Merger is consummated, all costs and expenses incurred
         in connection with this Agreement, the Stock Option Agreement
         and the transactions contemplated hereby and thereby shall be
         paid by the party incurring such expense, except (i) as
         otherwise provided below in this Section 5.07 and (ii) that
         filing fees and expenses incurred in connection with the fil-
         ing, printing and mailing of the Proxy Statement shall be
         shared equally by Parent and the Company.

                   (b)  If this Agreement is terminated pursuant to its
         terms, other than by Parent or the Company pursuant to Section
         7.01(b)(i) or (iii) or by the Company pursuant to Section
         7.01(b)(ii), and an Acquisition Event shall occur after the
         date hereof and prior to the date that is 18 months after the
         date of such termination, the Company shall upon demand by
         Parent, pay or cause to be paid, in same day funds to Parent
         the sum of (i) all of Parent's Expenses (as defined below) in
         an amount up to but not exceeding U.S. $10,000,000 and (ii)
         U.S. $50,000,000 (the "Termination Fee").  "Acquisition Event"
         shall mean any of the following:  (i) any person or group (as
         defined in Section 13(d)(3) of the Exchange Act), other than
         Parent or any of its subsidiaries, shall have acquired, pur-
         suant to a tender offer, exchange offer or otherwise, benefi-
         cial ownership (including pursuant to the acquisition of
         options) of 20% or more of any class of equity securities of
         the Company or any of its subsidiaries; (ii) any such person or
         group shall have received approval from the Federal Reserve to
         acquire ownership of 20% or more of any class of equity secu-
         rities of the Company or MNB; or (iii) the Company or MNB shall
         have authorized, recommended, proposed or publicly announced an
         intention to authorize, recommend or propose, shall have
         amended the Rights Agreement to facilitate, or shall have
         entered into, an agreement with any person (other than Parent
         or a subsidiary thereof) to (w) effect a merger, consolidation,
         business combination, sale of substantially all assets, or
         similar transaction involving the Company or MNB, (x) sell,
         lease or otherwise dispose of assets of the Company or its
         subsidiaries representing 15% or more of the consolidated
         assets of the Company and its subsidiaries, (y) issue, sell or
         otherwise dispose of (including by way of merger, consolida-
         tion, share exchange, or any similar transaction) securities


                                       -39-<PAGE>







         representing 20% or more of any class of equity securities of
         the Company or any of its subsidiaries or (z) have such person
         effect a tender offer or exchange offer that if consummated
         would result in any person beneficially owning 20% or more of
         any class of equity securities of the Company or any of its
         subsidiaries.  "Expenses" shall mean all out-of-pocket fees and
         expenses incurred or paid by or on behalf of Parent or any of
         its affiliates in connection with the Merger or the consumma-
         tion of any of the other transactions contemplated by this
         Agreement or the Stock Option Agreement, including all fees and
         expenses of counsel, commercial banks, investment banking
         firms, accountants, experts and consultants to Parent or any of
         its affiliates.  The amount of Expenses so payable shall be the
         amount set forth in an estimate delivered by Parent, subject to
         upward or downward adjustment upon delivery of reasonable
         documentation therefor.

                   (c)  Notwithstanding anything to the contrary con-
         tained herein, the aggregate amount of gain realized by Grantee
         pursuant to the Stock Option Agreement from the Company (or the
         Substitute Option Issuer (as defined in the Stock Option
         Agreement)), when added to the Termination Fee, if any,
         received by Parent pursuant to Section 5.07(b), shall not in
         the aggregate exceed U.S. $75,000,000, and, in the event Parent
         realizes gain in excess of such amount under the Stock Option
         Agreement from the Company (or the Substitute Option Issuer) or
         under the Termination Fee, Parent hereby undertakes promptly to
         pay back to the Company, by wire transfer of immediately
         available funds, the amount of such excess.

                   SECTION 5.08.  Indemnification, Exculpation and
         Insurance.  (a)  Parent and Sub agree that, for a period of six
         years (or the period of the applicable statute of limitations,
         if longer) from the Effective Time, all rights to indemnifi-
         cation and exculpation from liability for acts or omissions
         occurring prior to the Effective Time now existing in favor of
         the current or former directors or officers of the Company and
         its subsidiaries (such persons, "Indemnified Persons") as
         provided in their respective articles of incorporation (or
         similar constitutive documents) or by-laws shall survive the
         Merger and shall not be amended, repealed or otherwise modified
         in any manner that would adversely affect the rights thereunder
         of any such Indemnified Persons.  Parent will cause to be
         maintained for a period of six years from the Effective Time
         the Company's current directors' and officers' insurance and
         indemnification policy (a copy of which has heretofore been
         delivered to Parent) to the extent that it provides coverage
         for events occurring prior to the Effective Time (the "D&O
         Insurance") for all persons who are directors and officers of
         the Company on the date of this Agreement, so long as the


                                       -40-<PAGE>







         annual premium therefor would not be in excess of (i) until the
         third anniversary of the Effective Time, 200%, and (ii) there-
         after, 100%, of the last annual premium paid prior to the date
         of this Agreement (in the case of either clause (i) or (ii)
         above, the "Maximum Premium"); provided, however, that Parent
         may, in lieu of maintaining such existing D&O Insurance as
         provided above, cause comparable coverage to be provided under
         any policy maintained for the benefit of Parent or any of its
         subsidiaries, so long as the material terms thereof are no less
         advantageous than the existing D&O Insurance.  If the existing
         D&O Insurance expires, is terminated or cancelled during such
         three-year period, Parent will use all reasonable efforts to
         cause to be obtained as much D&O Insurance as can be obtained
         for the remainder of such period for an annualized premium not
         in excess of the Maximum Premium, on terms and conditions no
         less advantageous than the existing D&O Insurance.  The Company
         represents to Parent that the Maximum Premium is U.S.
         $1,230,000 for the first three years and U.S. $615,000 there-
         after.

                   (b)  The provisions of this Section 5.08 are intended
         to be for the benefit of, and shall be enforceable by, each
         Indemnified Party and each Indemnified Party's heirs and rep-
         resentatives.

                   SECTION 5.09.  Company Accruals and Reserves.  Prior
         to the Closing Date, at the request of Parent, the Company
         shall review and, to the extent mutually determined to be
         necessary or advisable, consistent with GAAP and the accounting
         rules, regulations and interpretations of the SEC and its
         staff, modify and change its loan, accrual and reserve policies
         and practices (including loan classifications and levels of
         reserves and accruals to (a) reflect the Surviving Corpora-
         tion's plans with respect to the conduct of the Company's
         business following the Merger and (b) make adequate provision
         for the costs and expenses relating thereto) so as to be
         applied consistently on a basis that is mutually satisfactory
         to each of the Company and Parent.  Notwithstanding the fore-
         going, the Company shall not be obligated to take in any
         respect any such action pursuant to this Section 5.09 unless
         and until Parent acknowledges that all conditions to its
         obligation to consummate the Merger have been satisfied.

                   SECTION 5.10.  Rights Agreement.  The Board of
         Directors of the Company shall take all further action (in
         addition to that referred to in Section 3.01(p)) requested in
         writing by Parent in order to render the Rights inapplicable to
         the Merger, the Stock Option Agreement and the other trans-
         actions contemplated by this Agreement and the Stock Option
         Agreement.  Except as requested in writing by Parent, during


                                       -41-<PAGE>







         the term of this Agreement, the Board of Directors of the
         Company shall not (i) amend the Rights Agreement or (ii) take
         any action with respect to, or make any determination under,
         the Rights Agreement, including a redemption of the Rights or
         any action to facilitate a takeover proposal; provided that any
         of such actions may be taken simultaneously with entering into
         an agreement in respect of such takeover proposal pursuant to
         Section 4.02(b).

                   SECTION 5.11.  Company Debentures.  The Company shall
         deliver, as promptly as practicable following receipt of Fed-
         eral Reserve approval for such redemption and cancellation, a
         notice to holders of the Company Debentures and the Equity
         Contracts of the Company's irrevocable intention to redeem, on
         a specified date not earlier than 60 days nor later than 90
         days following the date of such notice, all the outstanding
         Company Debentures in accordance with their terms and to cause
         the cancellation of all the outstanding Equity Contracts in
         accordance with their terms.  On such specified date, the
         Company shall duly effect such redemptions and such cancella-
         tions, in each case in accordance with the respective provi-
         sions of the Company Debentures and the Equity Contracts.

                   SECTION 5.12.  Additional Agreements.  In case at any
         time after the Effective Time any further action is necessary
         or desirable to carry out the purposes of this Agreement or to
         vest the Surviving Corporation with full title to all proper-
         ties, assets, rights, approvals, immunities and franchises of
         either of the Company or Parent, the proper officers and
         directors of each party to this Agreement shall take all such
         necessary action.

                   SECTION 5.13.  Parent Covenants.  (a)  Other Actions.
         Parent shall not, nor shall it permit any of its subsidiaries
         to, take any action that would, or reasonably could be expected
         to, result in any of its representations and warranties set
         forth in this Agreement that are qualified as to materiality
         being or becoming untrue, any of such representations and
         warranties that are not so qualified being or becoming untrue
         in any material respect, any of the conditions to the Merger
         set forth in Article VI not being satisfied or a material
         Violation of any provision of the Stock Option Agreement, or
         (unless such action is required by applicable law or sound
         banking practice) which could reasonably be expected to
         adversely affect or delay the ability of any of Parent, Sub or
         the Company or their subsidiaries to obtain any of the Requi-
         site Regulatory Approvals without imposition of a condition or
         restriction of the type referred to in Section 6.02(c).

                   (b)  Advice of Changes; Government Filings.  Parent
         shall file all reports required to be filed by it with the SEC
         or the applicable self-regulatory organization between the date
         of this Agreement and the Effective Time and shall deliver to
         the Company copies of all such reports promptly after the same
         are filed.  Parent and each subsidiary of Parent that is a bank
         shall file all Call Reports with the appropriate Regulatory
         Authorities and all other reports, applications and other
         documents required to be filed with the Federal Reserve and the
         other Regulatory Authorities between the date hereof and the
         Effective Time and shall make available to the Company copies
         of all such reports promptly after the same are filed.  Except
         where prohibited by applicable statutes and regulations, Parent
         shall promptly provide the Company (or its counsel) with copies
         of all other filings made by Parent with any state or Federal
         Governmental Entity in connection with this Agreement, the
         Stock Option Agreement or the transactions contemplated hereby
         or thereby.

                   SECTION 6.01.  Conditions to Each Party's Obligation
         To Effect the Merger.  The respective obligations of each party

         hereby shall be subject to the satisfaction or waiver at or
         prior to the Effective Time of the following conditions:

                   (a)  Company Stockholder Approval.  The Company
              Stockholder Approval shall have been obtained.

                   (b)  Other Approvals.  Other than the filing provided
              for by Section 1.03, all authorizations, consents, orders
              or approvals of, or declarations or filings with, and all
              expirations of waiting periods imposed by, any Govern-
              mental Entity (all the foregoing, "Consents") which are
              necessary for the consummation of the Merger, other than
              Consents the failure to obtain which would not, indi-
              vidually or in the aggregate, have a Material Adverse
              Effect on the Surviving Corporation or which would not,
              individually or in the aggregate, materially adversely
              affect the consummation of the transactions contemplated
              hereby, shall have been filed, occurred or been obtained
              (all such Consents and the lapse of all such waiting
              periods being referred to as the "Requisite Regulatory
              Approvals"), and all such Requisite Regulatory Approvals
              shall be in full force and effect.

                   (c)  No Injunctions or Restraints; Illegality.  No
              temporary restraining order, preliminary or permanent
              injunction or other order or decree issued by any court of
              competent jurisdiction or other legal restraint or pro-
              hibition preventing the consummation of the Merger shall
              be in effect; provided, however, that each of the parties
              shall have used reasonable efforts to prevent the entry of
              any such injunction or other order or restraint and to
              appeal as promptly as possible any injunction or other
              order or restraint that may be entered.  There shall not
              be any action taken, or any statute, rule, regulation or
              order enacted, entered, enforced or deemed applicable to
              the Merger, which makes the consummation of the Merger
              illegal.

                   SECTION 6.02.  Conditions to Obligations of Parent.
         The obligations of Parent and Sub to effect the Merger are
         subject to the satisfaction of the following conditions unless
         waived by Parent and Sub:

                   (a)  Representations and Warranties.  The represen-
              tations and warranties of the Company (i) set forth in
              this Agreement (other than those described in clause (ii)
              hereof) that are qualified as to materiality shall be true
              and correct, and any such representations and warranties
              that are not so qualified shall be true and correct in all
              material respects and (ii) set forth in the last sentence
              of Section 3.01(f)(i), Section 3.01(f)(ii)(A) and the last
              two sentences of Section 3.01(q) except to the extent that
              any inaccuracies, either individually or in the aggregate,
              could not reasonably be expected to result in or consti-
              tute a Material Adverse Effect on the Company; in the case
              of all such representations and warranties referred to in
              clause (i) and (ii) hereof both as of the date of this
              Agreement and (except to the extent such representations
              and warranties speak as of an earlier date) as of the
              Closing Date as though made on and as of the Closing Date,
              except as otherwise contemplated by this Agreement, and
              Parent shall have received a certificate signed on behalf
              of the Company by its Chairman or Chief Executive Officer
              and its Chief Financial Officer or other executive officer
              performing duties equivalent to those of a "chief finan-
              cial officer" to such effect.

                   (b)  Performance of Obligations of the Company.  The
              Company shall have performed in all material respects all
              obligations required to be performed by it under this
              Agreement at or prior to the Closing Date, and Parent
              shall have received a certificate signed on behalf of the
              Company by its Chairman or Chief Executive Officer and its


                                       -44-<PAGE>







              Chief Financial Officer or other executive officer per-
              forming duties equivalent to these of a "chief financial
              officer" to such effect.

                   (c)  Burdensome Condition.  There shall not be any
              action taken, or any statute, rule, regulation or order
              enacted, entered, enforced or deemed applicable to the
              Merger, by any Governmental Entity which, in connection
              with the grant of a Requisite Regulatory Approval, imposes
              any requirement upon Parent, the Company or the Surviving
              Corporation or their respective subsidiaries to (i) dis-
              pose of any asset which is material to Parent, the Company
              or the Surviving Corporation, (ii) materially restrict or
              curtail the current business operations or activities of
              Parent, or (iii) raise an amount of capital, the issuance
              and sale of which, in the absence of the Merger and the
              other transactions contemplated by this Agreement, would
              in the good faith judgment of Parent be materially bur-
              densome in light of such person's capital raising poli-
              cies.

                   (d)  Company Debentures and Equity Contracts.  The
              Company shall have duly effected the redemption of all the
              outstanding Company Debentures and the cancellation of all
              the outstanding Equity Contracts.

                   (e)  Company Stock Options and Company Stock Plans.
              The Company shall have duly effected, as of the Effective
              Time, the cancellation of all outstanding Company Stock
              Options, whether vested or not (the holders of which shall
              then be entitled to receive from Parent the amounts
              determined in accordance with Section 5.06(a)), the ter-
              mination of the Company Stock Plans (other than, subject
              to Section 5.06(d), the ESOP) and the deletion of any
              provision in any other Company Benefit Plan providing for
              the issuance, transfer or grant of any capital stock of
              the Company or any subsidiary of the Company or any
              interest in respect of any capital stock of the Company or
              any subsidiary of the Company.

                   (f)  Rights Agreement.  The Rights Agreement shall be
              inapplicable to the Merger and the other transactions
              contemplated by this Agreement.

                   SECTION 6.03.  Conditions to Obligations of the
         Company.  The obligations of the Company to effect the Merger
         are subject to the satisfaction of the following conditions
         unless waived by the Company:




                                       -45-<PAGE>







                   (a)  Representations and Warranties.  The represen-
              tations and warranties of Parent and Sub set forth in this
              Agreement that are qualified as to materiality shall be
              true and correct, and any such representations and war-
              ranties that are not so qualified shall be true and cor-
              rect in all material respects, in either case as of the
              date of this Agreement and (except to the extent such
              representations speak as of an earlier date) as of the
              Closing Date as though made on and as of the Closing Date,
              except as otherwise contemplated by this Agreement, and
              the Company shall have received a certificate signed on
              behalf of Parent and Sub by their respective Chairman or
              Chief Executive Officers and their respective Chief
              Financial Officers or other executive officers performing
              duties equivalent to these of a "chief financial officer"
              to such effect.

                   (b)  Performance of Obligations of Parent and Sub.
              Parent and Sub shall have performed in all material
              respects all obligations required to be performed by them
              under this Agreement and the Stock Option Agreement at or
              prior to the Closing Date, and the Company shall have
              received a certificate signed on behalf of Parent and Sub
              by their respective Chairman or Chief Executive Officers
              and their respective Chief Financial Officers or other
              executive officers performing duties equivalent to these
              of a "chief financial officer" to such effect.

                                   ARTICLE VII

                            Termination and Amendment

                   SECTION 7.01.  Termination.  This Agreement may be
         terminated at any time prior to the Effective Time, whether
         before or after the Company Stockholder Approval is received:

                   (a)  by mutual written consent of Parent and the
              Company;

                   (b)  by either Parent or the Company upon written
              notice to the other party:

                        (i)  if (1) the Federal Reserve or any other
                   Governmental Entity the approval of which is required
                   to permit consummation of the Merger or the other
                   transactions contemplated hereby shall have issued an
                   order denying approval of the Merger or such other





                                       -46-<PAGE>







                   transactions or (2) any Governmental Entity of com-
                   petent jurisdiction shall have issued a final per-
                   manent order enjoining or otherwise prohibiting the
                   consummation of the Merger or the other transactions
                   contemplated hereby and in any such case under either
                   clause (1) or (2) the time for appeal or petition for
                   reconsideration of such order shall have expired
                   without such appeal or petition being granted;

                       (ii)  if the Company, on the one hand, or Parent
                   or Sub, on the other hand, materially breaches any of
                   its covenants and obligations hereunder or under the
                   Stock Option Agreement and such breach is not cured
                   after 30 days' written notice thereof is given to the
                   party committing such breach by the other party; 

                      (iii)  if the Merger shall not have been consum-
                   mated on or before February 5, 1996, unless the
                   failure to consummate the Merger is the result of a
                   willful and material breach of this Agreement by the
                   party seeking to terminate this Agreement; or

                       (iv)  if, upon a vote at a duly held Company
                   Stockholders Meeting, the Company Stockholder
                   Approval shall not have been obtained;

                   (c)  by either Parent or Sub upon written notice to
              the Company:

                        (i)  if, prior to the Company Stockholders
                   Meeting, a takeover proposal is commenced, publicly
                   proposed, publicly disclosed or communicated to the
                   Company (or the willingness of any person to make a
                   takeover proposal is publicly disclosed or commu-
                   nicated to the Company) and (A) the Company Stock-
                   holder Approval is not obtained at the Company
                   Stockholders Meeting, (B) the Company Stockholders
                   Meeting does not occur prior to 120 days after the
                   date of this Agreement or (C) the Board of Directors
                   of the Company or any committee thereof shall have
                   withdrawn or modified its approval or recommendation
                   of the Merger or this Agreement, or approved or
                   recommended any takeover proposal; or

                       (ii)  if the Company shall have entered into any
                   agreement with respect to any superior proposal in
                   accordance with Section 4.02(b); or

                   (d)  by the Company in connection with entering into
              a definitive agreement in accordance with Section 4.02(b),


                                       -47-<PAGE>







              provided it has complied with all provisions thereof,
              including the notice provisions therein, and that it makes
              simultaneous payment of the Expenses and the Termination
              Fee in accordance with Section 5.07(b).

                   SECTION 7.02.  Effect of Termination.  In the event
         of termination of this Agreement by either the Company or
         Parent as provided in Section 7.01, this Agreement shall
         forthwith become void and have no effect, and there shall be no
         liability or obligation on the part of Parent, Sub, the Company
         or their respective officers or directors, except (a) with
         respect to Section 3.01(u), Section 3.02(e), the second sen-
         tence of Section 5.02, Section 5.07, this Section 7.02 and
         Article VIII, (b) with respect to the representations and
         warranties contained in Sections 3.01 and 3.02 insofar as such
         representations and warranties relate to the Stock Option
         Agreement (but only until the termination of the Stock Option
         Agreement) and (c) to the extent that such termination results
         from the willful and material breach by the other party of any
         of its representations, warranties, covenants or agreements set
         forth in this Agreement.

                   SECTION 7.03.  Amendment.  This Agreement may be
         amended by the parties hereto at any time before or after the
         Company Stockholder Approval is received, but, after receipt of
         the Company Stockholder Approval, no amendment shall be made
         which by law requires further approval by such stockholders
         without such further approval.  This Agreement may not be
         amended except by an instrument in writing signed on behalf of
         each of the parties hereto; provided, however, that, notwith-
         standing anything to the contrary contained in this Section
         7.03, Parent may from time to time without the consent of the
         Company increase the amount (but not change the nature) of the
         Merger Consideration, and any provisions inconsistent with such
         right herein or in any agreement referred to herein are hereby
         deemed superseded to the extent of such inconsistency.

                   SECTION 7.04.  Extension; Waiver.  At any time prior
         to the Effective Time, the parties hereto may, to the extent
         legally allowed, (a) extend the time for the performance of any
         of the obligations or other acts of the other parties hereto,
         (b) waive any inaccuracies in the representations and warran-
         ties contained herein or in any document delivered pursuant
         hereto and (c) subject to the proviso of Section 7.03, waive
         compliance with any of the agreements or conditions contained
         herein.  Any agreement on the part of a party hereto to any
         such extension or waiver shall be valid only if set forth in a
         written instrument signed on behalf of such party.  The failure
         of any party to this Agreement to assert any of its rights



                                       -48-<PAGE>







         under this Agreement or otherwise shall not constitute a waiver
         of those rights.

                   SECTION 7.05.  Procedure for Termination, Amendment,
         Extension or Waiver.  A termination of this Agreement pursuant
         to Section 7.01, an amendment of this Agreement pursuant to
         Section 7.03 or an extension or waiver pursuant to Section 7.04
         shall, in order to be effective, require, in the case of Par-
         ent, Sub or the Company, action by its Board of Directors or
         the duly authorized designee of its Board of Directors.

                                   ARTICLE VIII

                                General Provisions

                   SECTION 8.01.  Nonsurvival of Representations and
         Warranties.  None of the representations and warranties in this
         Agreement or in any instrument delivered pursuant to this
         Agreement shall survive the Effective Time.  This Section 8.01
         shall not limit any covenant or agreement of the parties which
         by its terms contemplates performance after the Effective Time.

                   SECTION 8.02.  Notices.  All notices and other com-
         munications hereunder shall be in writing and shall be deemed
         given if delivered personally, telecopied (with confirmation)
         or mailed by registered or certified mail (return receipt
         requested) to the parties at the following addresses (or at

                   SECTION 8.06.  Governing Law.  This Agreement shall
         be governed and construed in accordance with the laws of the
         State of Michigan, without regard to any applicable principles
         of conflicts of law.

                   SECTION 8.07.  Limitations on Remedies.  Each party
         agrees that, should any court or other competent authority hold
         any provision of this Agreement or the Stock Option Agreement
         or part hereof or thereof to be null, void or unenforceable, or
         order any party to take any action inconsistent herewith or not
         to take any action required herein, the other party shall not
         be entitled to specific performance of such provision or part
         hereof or thereof or to any other remedy, including money
         damages, for breach hereof or thereof or of any other provision
         of this Agreement or the Stock Option Agreement or part hereof
         or thereof as a result of such holding or order.  This provi-
         sion is not intended to render null or unenforceable any
         obligation hereunder that would be valid and enforceable if
         this provision were not in this Agreement.

                   SECTION 8.08.  Publicity.  Except as otherwise
         required by law or the rules of the NYSE or Nasdaq, so long as
         this Agreement is in effect, neither the Company nor Parent
         shall, or shall permit any of its subsidiaries to, issue or
         cause the publication of any press release or other public
         announcement with respect to the transactions contemplated by
         this Agreement or the Stock Option Agreement without the con-
         sent of the other party, which consent shall not be unreason-
         ably withheld.  The parties agree that the initial press
         release to be issued with respect to the transactions contem-
         plated by this Agreement shall be in the form heretofore agreed
         to by the parties.

                   SECTION 8.09.  Assignment.  Neither this Agreement
         nor any of the rights, interests or obligations hereunder shall
         be assigned, in whole or in part, by any of the parties hereto
         (whether by operation of law or otherwise) without the prior
         written consent of the other parties, and any such assignment
         that is not so consented to shall be null and void.  Subject to
         the preceding sentence, this Agreement will be binding upon,
         inure to the benefit of and be enforceable by the parties and
         their respective successors and assigns.

                   SECTION 8.10.  Enforcement.  Subject to Section 8.07,
         the parties agree that irreparable damage would occur in the
         event that any of the provisions of this Agreement were not
         performed in accordance with their specific terms or were
         otherwise breached.  It is accordingly agreed that, subject to
         Section 8.07, the parties shall be entitled to an injunction or
         injunctions to prevent breaches of this Agreement and to


                                       -52-<PAGE>







         enforce specifically the terms and provisions of this Agreement
         in any Federal court located in the State of New York or in any
         New York state court, this being in addition to any other
         remedy to which they are entitled at law or in equity.  In
         addition, each of the parties hereto (a) consents to submit
         itself to the personal jurisdiction of any Federal court
         located in the State of New York or any New York state court in
         the event any dispute arises out of this Agreement or any of
         the transactions contemplated by this Agreement and (b) agrees
         that it will not attempt to deny or defeat such personal
         jurisdiction by motion or other request for leave from any such
         court.

                             STOCK OPTION AGREEMENT dated as of February
                        4, 1995, among NATIONAL AUSTRALIA BANK LIMITED
                        A.C.N. 004044937, an Australian corporation
                        ("Grantee"), MNC ACQUISITION CO., a Michigan
                        corporation and a wholly owned subsidiary of
                        Grantee ("Sub"), and MICHIGAN NATIONAL CORPO-
                        RATION, a Michigan corporation ("Issuer").


                   WHEREAS Issuer is a registered bank holding company
         under the Bank Holding Company Act of 1956, as amended (the
         "BHC Act");

                   WHEREAS Grantee is a commercial bank under Australian
         law and is a foreign bank within the meaning of the Interna-
         tional Banking Act of 1978, as amended;

                   WHEREAS Grantee, Sub and Issuer propose to enter into
         an Agreement and Plan of Merger dated as of the date hereof
         (the "Merger Agreement");

                   WHEREAS, as a condition and inducement to Grantee's
         and Sub's willingness to enter into the Merger Agreement,
         Grantee and Sub have required that Issuer grant to Grantee the
         Option (as defined in Section 2); and

                   WHEREAS the Board of Directors of Issuer, believing
         it to be in the best interests of Issuer, has approved this
         Agreement and the grant by Issuer of the Option.

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

                   1.  Definitions; Interpretation.  Capitalized terms
         used but not defined herein shall have the meanings set forth
         in the Merger Agreement, which also contains in Section 8.03(b)
         thereof certain rules of construction and interpretation that
         shall be applicable hereto as if set forth herein.

                   2.  Grant of Option.  Issuer hereby grants to Grantee
         an unconditional, irrevocable option (the "Option") to pur-
         chase, subject to the terms hereof, up to 2,633,502 fully paid
         and nonassessable shares (such amount, as may be adjusted from
         time to time as set forth herein, the "Option Shares") of
         Common Stock, par value $10 per share ("Issuer Common Stock"),
         of the Issuer at a purchase price of U.S. $89.00 per Option
         Share (such price, as may be adjusted from time to time as set
         forth herein, the "Option Price").  The number of Option Shares<PAGE>







         that may be received upon the exercise of the Option and the
         Option Price are subject to adjustment as set forth in Section
         6.

                   2.  Exercise of Option.  (a)  Grantee may exercise
         the Option, in whole or part, at any time and from time to time
         on or after the date hereof if a Triggering Event (as defined
         below) shall have occurred; provided, however, that, to the
         extent the Option shall not have been exercised, it shall
         terminate and be of no further force and effect upon the ear-
         liest of (i) the Effective Time of the Merger, (ii) termination
         of the Merger Agreement pursuant to Section 7.01 thereof (other
         than for any of the reasons described in clause (iii) below) or
         (iii) 18 months after termination of the Merger Agreement (x)
         by either party under Section 7.01(c) or (d) thereof, (y) by
         Grantee under Section 7.01(b)(ii) thereof or (z) by Issuer
         under Section 7.01(b)(iv) under circumstances where Grantee
         could effect termination pursuant to Section 7.01(c); provided
         further that, any such exercise and purchase of Option Shares
         shall be subject to compliance with applicable laws, including
         the BHC Act.  The rights set forth in Sections 8, 9 and 10
         shall not terminate when the right to exercise the option
         terminates as set forth herein, but shall extend to such time
         as is provided in such Sections 8, 9 and 10.  Notwithstanding
         the termination of the Option, Grantee shall be entitled to
         purchase those Option Shares with respect to which it has ex-
         ercised the Option in accordance with the terms hereof prior to
         the termination of the Option.

                   (b)  A "Triggering Event" means the occurrence of an
         Acquisition Event, as defined in Section 5.07(b) of the Merger
         Agreement (without regard to whether the Merger Agreement is
         terminated).

                   (c)  Issuer shall notify Grantee promptly in writing
         of the occurrence of any Triggering Event; provided that it is
         understood that the giving of such notice by Issuer shall not
         be a condition to the right of Grantee to exercise the Option.

                   (d)  In the event Grantee is entitled to and wishes
         to exercise the Option, it shall send to Issuer a written no-
         tice (the date of which being referred to herein as the "Notice
         Date") specifying (i) the total number of Option 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 (a
         "Closing Date"); provided that if prior notification to or
         approval of the Federal Reserve Board (the "Federal Reserve")
         or any other Governmental Entity is required in connection with
         such purchase, Grantee shall promptly file the required notice


                                       -2-<PAGE>







         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 instead from the date on which, as
         the case may be, (A) any required notification periods have
         expired or been terminated or (B) such approvals have been
         obtained and any requisite waiting period or periods shall have
         passed.

                   (e)  Notwithstanding Section 3(d), in no event shall
         any Closing Date be more than 18 months after the related No-
         tice Date, and if the Closing Date shall not have occurred
         within 18 months after the related Notice Date due to the
         failure to obtain any such required approval, the exercise of
         the Option effected on the Notice Date shall be deemed to have
         expired.  In the event (i) Grantee receives official notice
         that an approval of the Federal Reserve or any other Govern-
         mental Entity required for the purchase of the Option Shares
         would not be issued or granted or (ii) a Closing Date shall not
         have occurred within 18 months after the related Notice Date
         due to the failure to obtain any such required approval,
         Grantee shall nevertheless be entitled to exercise its right as
         set forth in Section 8 or to exercise the Option in connection
         with the resale of Issuer Common Stock or other securities
         pursuant to a registration statement as provided in Section 10.
         The provisions of this Section 3 and Section 4 shall apply with
         appropriate adjustments to any such exercise.

                   4.  Payment and Delivery of Certificates.  (a)  On
         each Closing Date referred to in Section 3(d), Grantee shall
         pay to Issuer in immediately available funds by a wire transfer
         to a bank account designated by Issuer an amount equal to the
         Option Price multiplied by the number of Option Shares to be
         purchased on such Closing Date.

                   (b)  On each Closing Date, simultaneously with the
         delivery of immediately available funds as provided in Section
         4(a), Issuer shall deliver to Grantee a certificate or cer-
         tificates representing the Option Shares to be purchased on
         such Closing Date.  If the Option should be exercised in part
         only, a new Option evidencing the rights of Grantee to purchase
         the balance of the Option Shares purchasable hereunder shall be
         issued to Grantee, and Grantee shall deliver to Issuer a copy
         of this Agreement and a letter agreeing that Grantee will not
         offer to sell or otherwise dispose of such Option Shares in
         violation of applicable law or the provisions of this Agree-
         ment.

                   (c)  Certificates for Issuer Common Stock delivered
         on a Closing Date hereunder shall be endorsed with a restric-
         tive legend that shall read substantially as follows:


                                       -3-<PAGE>







              THE TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE
              IS SUBJECT TO CERTAIN RESALE RESTRICTIONS ARISING UNDER
              THE SECURITIES ACT OF 1933, AS AMENDED, AND PURSUANT TO
              THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF FEBRUARY
              4, 1995, A COPY OF WHICH AGREEMENT IS ON FILE AT THE
              PRINCIPAL OFFICE OF ISSUER.  A COPY OF SUCH AGREEMENT WILL
              BE MAILED 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 "Securities Act"), in the above legend shall be removed by
         delivery of substitute certificate(s) without such reference if
         Grantee shall have delivered to Issuer a copy of a letter from
         the staff of the Securities and Exchange Commission, or an
         opinion of counsel, in form and substance satisfactory to Is-
         suer, to the effect that such legend is not required for pur-
         poses of the Securities Act; (ii) the reference to the provi-
         sions of this Agreement in the above legend shall be removed by
         delivery of substitute certificate(s) without such reference if
         the Option Shares have been sold or transferred in compliance
         with the provisions of this 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.

                   (d)  Upon the giving by Grantee to Issuer of the
         written notice of exercise of the Option provided for under
         Section 3(d), the tender of the applicable purchase price in
         immediately available funds and the tender of a copy of this
         Agreement to Issuer, Grantee shall be deemed to be the holder
         of record of the Option Shares issuable upon such exercise,
         notwithstanding that the stock transfer books of Issuer shall
         then be closed or that certificates representing such Option
         Shares shall not then be actually delivered to Grantee.  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 the preparation, issue and delivery of stock
         certificates under this Section 4 in the name of Grantee or its
         assignee, transferee or designee.

                   (e)  If, at the time of issuance of any Option Shares
         pursuant to an exercise of all or a portion of the Option here-
         under, Issuer shall not have redeemed the Rights or shall have
         issued any similar securities, then each Option Share issued
         pursuant to such exercise shall also represent Rights or new
         rights with terms substantially identical to and at least



                                       -4-<PAGE>







         as favorable to Grantee as are provided under the Rights
         Agreement or any similar agreement then in effect.

                   5.  Authorizations, etc.  Issuer agrees (i) that it
         shall at all times maintain, free from preemptive rights or
         Liens, sufficient authorized but unissued shares of Issuer
         Common Stock so that the Option may be exercised without ad-
         ditional authorization of Issuer Common Stock after giving
         effect to all other options, warrants, convertible securities
         and other rights to purchase Issuer Common Stock, (ii) that it
         will not, by charter amendment or through reorganization, re-
         capitalization, reclassification, consolidation, merger, dis-
         solution 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 and (iii) promptly to take all
         action as may from time to time be required (including, in the
         event, under the BHC Act or the Change in Bank Control Act of
         1978, as amended, or a state banking law, prior approval of or
         notice to the Federal Reserve or to any state regulatory au-
         thority is necessary before the Option may be exercised, co-
         operating fully with Grantee in preparing such applications or
         notices and providing such information to the Federal Reserve
         or such state regulatory authority as they may require) in
         order to permit Grantee to exercise the Option and so that the
         Option Shares, when issued, shall be duly authorized, validly
         issued, fully paid and nonassessable and free and clear of all
         Liens and not subject to any preemptive rights.

                   6.  Adjustments.  (a)  In the event that any addi-
         tional shares of Issuer Common Stock are issued or otherwise
         become outstanding after the date of this Agreement (other than
         pursuant to an exercise of the Option or an event described in
         Section 6(b)), including pursuant to stock option plans and in
         connection with acquisitions and other transactions permitted
         by the Merger Agreement, the number of Option Shares shall be
         increased so that, after such issuance, it equals 19.9% of the
         number of shares of Issuer Common Stock then issued and out-
         standing (without giving pro forma effect to the issuance of
         the Option Shares).  Nothing contained in this Section 6(a) or
         elsewhere in this Agreement shall be deemed to authorize Issuer
         to issue shares of Issuer Common Stock in breach of, or oth-
         erwise breach any of, the provisions of the Merger Agreement.

                   (b)  In the event of any change in Issuer Common
         Stock by reason of a stock dividend, split-up, recapitaliza-
         tion, combination, subdivision, conversion, exchange of shares
         or similar transaction, the type and number of Option Shares
         shall be appropriately adjusted and proper provision shall be
         made in the agreements governing any such transaction, so that


                                       -5-<PAGE>







         Grantee shall receive upon exercise of the Option the number
         and class of shares, other securities, property or cash that
         Grantee would have received in respect of Issuer Common Stock
         if the Option had been exercised in full and the Option Shares
         had been issued to Grantee immediately prior to such event or
         the record date therefor, as applicable.  Whenever the number
         of Option Shares is adjusted as provided in this Section 6(b),
         the Option Price shall be adjusted by multiplying the Option
         Price by a fraction, the numerator of which is equal to the
         number of Option Shares purchasable prior to the adjustment and
         the denominator of which is equal to the number of Option
         Shares purchasable after the adjustment.

                   7.  Replacement Options.  (a)  In the event that
         Issuer shall enter into an agreement (i) to consolidate with or
         merge into any person, other than Grantee or one of its sub-
         sidiaries, and shall not be the continuing or surviving cor-
         poration 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 Issuer Common Stock shall be changed into
         or exchanged for stock or other securities of Issuer or any
         other person or cash or any other property or the then out-
         standing shares of Issuer 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 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 con-
         summation of any such transaction and upon the terms and con-
         ditions set forth herein, be converted into, or exchanged for,
         an option (the "Substitute Option"), at the election of
         Grantee, of either (A) the Acquiring Corporation (as defined
         below) or (B) any person that controls the Acquiring Corpora-
         tion.

                   (b)  The following terms have the meanings indicated:

                   (i)  "Acquiring Corporation" shall mean (A) the con-
              tinuing or surviving corporation of a consolidation or
              merger with Issuer (if other than Issuer), (B) Issuer in a
              merger in which Issuer is the continuing or surviving
              person or (C) the transferee of all or substantially all
              of Issuer's assets.

                  (ii)  "Substitute Common Stock" shall mean the common
              stock issued by the issuer of the Substitute Option upon
              exercise of the Substitute Option.


                                       -6-<PAGE>







                 (iii)  "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 the 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 con-
              trolled by such person, as Grantee 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 Grantee.  The issuer of the Substitute Option
         (the "Substitute Option Issuer") shall also enter into an
         agreement with Grantee in substantially the same form as this
         Agreement, which shall be applicable to the Substitute Option.
         Without limiting the generality of the foregoing, the provi-
         sions of Sections 8, 9, 10, 11 and 12 shall apply with respect
         to the Substitute Option and any securities for which the
         Substitute Option becomes exercisable with the same effect as
         if all references to "Issuer" in such Sections were references
         to "Substitute Option Issuer", all references to "Issuer Common
         Stock" were references to "Substitute Common Stock", all ref-
         erences to the "Option" were references to the "Substitute
         Option" and all references to "Option Shares" were references
         to "Substitute Option Shares".

                   (d)  The Substitute Option shall be exercisable for
         such number of shares of Substitute Common Stock as is equal to
         the then-current Applicable Price (as defined in Section 8(c))
         multiplied by the number of shares of Issuer Common Stock for
         which the Option is then exercisable, divided by the then-
         current 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 in which the nu-
         merator is the number of shares of Issuer Common Stock for
         which the Option is then exercisable and the denominator is the
         number of shares of the 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 the 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


                                       -7-<PAGE>







         prior to such exercise but for the limitation in this paragraph
         (e), the Substitute Option Issuer shall make a cash payment to
         Grantee equal to the excess of (i) the value of the Substitute
         Option without giving effect to the limitation in this para-
         graph (e) over (ii) the value of the Substitute Option after
         giving effect to the limitation in this paragraph (e).  This
         difference in value shall be determined by a nationally rec-
         ognized investment banking firm selected by Grantee.

                   (f)  Issuer shall not enter into any transaction de-
         scribed in Section 7(a) unless the Acquiring Corporation and
         any person that controls the Acquiring Corporation assume in
         writing all the obligations of Issuer hereunder.

                   8.  Repurchase at the Option of Grantee.  (a)  At the
         request of Grantee at any time during (i) the period during
         which the Option is exercisable pursuant to Section 3 or (ii)
         the period of 30 business days immediately following the oc-
         currence of either of the events set forth in clauses (i) and
         (ii) of the second sentence of Section 3(e) (but solely as to
         the shares of Issuer Common Stock with respect to which the
         required approval was not received) (either such period being
         referred to herein as the "Repurchase Period"), Issuer (or any
         successor entity thereof) shall repurchase from Grantee (A) the
         Option (or, in the circumstances set forth in clause (ii)
         above, that portion thereof relating to shares of Issuer Common
         Stock with respect to which required approvals were not re-
         ceived) unless the Option has expired or been terminated in
         accordance with the terms hereof and (B) all Option Shares
         purchased by Grantee pursuant hereto with respect to which
         Grantee then has beneficial ownership.  The date on which
         Grantee exercises its rights under this Section 8 is referred
         to as the "Request Date".  Such repurchase shall be at an ag-
         gregate price (the "Section 8 Repurchase Consideration") equal
         to the sum of:

                   (1)  the aggregate exercise price paid by Grantee for
              any Option Shares acquired with respect to which Grantee
              then has beneficial ownership;

                   (2)  the excess, if any, of (x) the Applicable Price
              for shares of Issuer Common Stock over (y) the Option
              Price, with such excess multiplied by the number of Option
              Shares with respect to which the Option has not been ex-
              ercised; and

                   (3)  the excess, if any, of (x) the Applicable Price
              over (y) the Option Price paid (or, in the case of Option
              Shares with respect to which the Option has been exercised
              but the Closing Date has not occurred, payable) by Grantee


                                       -8-<PAGE>







              for each Option Share with respect to which the Option has
              been exercised, with such excess multiplied by the number
              of such Option Shares.

                   (b)  If Grantee exercises its rights under this Sec-
         tion 8, Issuer shall, within 10 business days after the Request
         Date, pay the Section 8 Repurchase Consideration to Grantee in
         immediately available funds, and Grantee shall surrender to
         Issuer the Option and the certificates evidencing the shares of
         Issuer Common Stock purchased thereunder with respect to which
         Grantee then has beneficial ownership, and Grantee shall war-
         rant that it has sole record and beneficial ownership of such
         shares and that the same are then free and clear of all Liens.
         Notwithstanding the foregoing, to the extent that prior noti-
         fication to or approval of the Federal Reserve or other Gov-
         ernmental Entity is required in connection with the payment of
         all or any portion of the Section 8 Repurchase Consideration,
         Issuer shall deliver from time to time that portion of the
         Section 8 Repurchase Consideration that it is not then so
         prohibited from paying and shall promptly file the required
         notice or application for approval and shall expeditiously
         process the same (and Grantee shall cooperate with Issuer in
         the filing of any such notice or application and the obtaining
         of any such approval), and the period of time that otherwise
         would run pursuant to the preceding sentence for the payment of
         the portion of the Section 8 Repurchase Consideration requiring
         such notification or approval shall run instead from the date
         on which, as the case may be, (i) any required notification
         period has expired or been terminated or (ii) such approval has
         been obtained and, in either event, any requisite waiting pe-
         riod shall have passed.  If the Federal Reserve or any other
         Governmental Entity disapproves of any part of Issuer's pro-
         posed repurchase pursuant to this Section 8, Issuer shall
         promptly give notice of such fact to Grantee and redeliver to
         Grantee the Option Shares it is then prohibited from repur-
         chasing, and Grantee shall have the right to exercise the Op-
         tion as to the number of Option Shares for which the Option was
         exercisable at the Request Date less the number of shares as to
         which payment has been made pursuant to Section 8(a)(2); pro-
         vided that if the Option shall have terminated prior to the
         date of such notice or shall be scheduled to terminate prior to
         the date of such notice or shall be scheduled to terminate at
         any time before the expiration of a period ending on the 30th
         business day after such date, Grantee shall nonetheless have
         the right so to exercise the Option or exercise its rights
         under Section 10 until the expiration of such period of 30
         business days.  Notwithstanding anything herein to the con-
         trary, Grantee shall be entitled to exercise its right under
         this Section 8 on only one occasion.



                                       -9-<PAGE>







                   (c)  For purposes of this Agreement, the "Applicable
         Price" means the highest of (i) the highest price per share at
         which a tender offer or exchange offer has been made for shares
         of Issuer Common Stock after the date hereof and on or prior to
         the Request Date (or any other applicable determination date),
         (ii) the price per share to be paid by any third party for
         shares of Issuer Common Stock or the consideration per share to
         be received by holders of Issuer Common Stock, in each case
         pursuant to an agreement with Issuer for a merger or other
         business combination entered into on or prior to the Request
         Date (or any other applicable determination date), (iii) the
         highest price per share paid by any third party to acquire from
         a stockholder of Issuer, in one transaction or in a series of
         related transactions, an aggregate amount of Issuer Common
         Stock of 5% or more of the outstanding Issuer Common Stock or
         (iv) the highest bid price per share of Issuer Common Stock as
         quoted on the Nasdaq over-the-counter quotations system or, if
         not so quoted, on the principal trading market on which such
         shares are traded as reported by a recognized source during the
         60 business days preceding the Request Date (or any other ap-
         plicable determination date).  If the consideration to be of-
         fered, paid or received pursuant to a transaction described in
         either clause (i) or (ii) above shall be other than cash, the
         value of such consideration shall be determined in good faith
         by an independent nationally recognized investment banking firm
         selected by Grantee and reasonably acceptable to Issuer, which
         determination shall be conclusive for all purposes of this
         Agreement.

                   9.  Repurchase at the Option of Issuer.  (a)  Except
         to the extent that Grantee shall have previously exercised its
         rights under Section 8, at the request of Issuer during the
         six-month period commencing 15 months following the first oc-
         currence of a Triggering Event, Issuer may repurchase from
         Grantee, and Grantee shall sell to Issuer, all (but not less
         than all) the shares of Issuer Common Stock acquired by Grantee
         pursuant hereto and with respect to which Grantee has benefi-
         cial ownership at the time of such repurchase at a price equal
         to the greater of (i) 110% of the Current Market Price (as
         defined below) or (ii) the sum of (A) the Option Price in re-
         spect of the shares so acquired and (B) Grantee's pre-tax per
         share carrying cost (as defined below), multiplied in the case
         of either clause (i) or (ii) above by the number of shares so
         acquired (the "Section 9 Repurchase Consideration"); provided
         that Grantee, within 30 days following Issuer's notice of its
         intention to purchase shares pursuant to this Section 9, may
         deliver an Offeror's Notice (as defined in Section 11) pursuant
         to Section 11, in which case the provisions of Section 11 and
         not those of this Section 9 shall control; and provided further
         that Issuer's rights under this Section 9 shall be suspended


                                       -10-<PAGE>







         (with any such rights being extended accordingly) during any
         period when the exercise of such rights would subject Grantee
         to liability pursuant to Section 16(b) of the Exchange Act by
         reason of Grantee's purchase of shares of Issuer Common Stock
         pursuant to this Agreement.

                   (b)  If Issuer exercises its rights under this Sec-
         tion 9 and Grantee does not deliver an Offeror's Notice or
         Grantee does not sell the shares to a third party pursuant
         thereto, Issuer shall, within 10 business days after the ex-
         piration of the 30-day period referred to in paragraph (a)
         above or, if applicable, upon abandonment of the transaction
         covered by the Offeror's Notice, pay the Section 9 Repurchase
         Consideration in immediately available funds, and Grantee shall
         surrender to Issuer the certificates evidencing the shares of
         Issuer Common Stock purchased hereunder with respect to which
         Grantee then has beneficial ownership, and Grantee shall war-
         rant that it has sole record and beneficial ownership of such
         shares and that the same are then free and clear of all Liens.

                   (c)  As used herein, (i) "Current Market Price" means
         the average closing bid price per share of Issuer Common Stock
         as quoted on the Nasdaq over-the-counter quotations system or,
         if not so quoted, on the principal trading market on which such
         shares are traded as reported by a recognized source for the 10
         business days preceding the date of the Issuer's request for
         repurchase pursuant to this Section 9 and (ii) "Grantee's pre-
         tax per share carrying cost" shall be the amount equal to the
         interest on the aggregate Option Price paid for the shares of
         Issuer Common Stock purchased from the date of purchase to the
         date of repurchase at the rate of interest announced by
         Parent's New York branch as its prime or base lending or ref-
         erence rate during such period, less any dividends received on
         the shares so purchased, divided by the number of shares so
         purchased.

                   10.  Registration Rights; Listing.  (a)  Issuer shall,
         if requested by Grantee at any time and from time to time (i)
         within three years of the first exercise of the Option or (ii)
         for 30 business days following the occurrence of either of the
         events set forth in clauses (i) and (ii) of the second sentence
         of Section 3(e) or receipt by Grantee of official notice that
         an approval of the Federal Reserve or any other Governmental
         Entity required for a repurchase as contemplated by Section
         8(b) would not be issued or granted (but solely as to the
         shares of Issuer Common Stock or portion of the Option with
         respect to which the required approval was not received), as
         expeditiously as practicable prepare and file up to two
         registration statements under the Securities Act if necessary
         in order to permit the sale or other disposition of the shares


                                       -11-<PAGE>







         of Issuer Common Stock or other securities that have been ac-
         quired by or are issuable to Grantee upon exercise of the Op-
         tion in accordance with the intended method of sale or other
         disposition stated by Grantee, including a "shelf" registration
         statement under Rule 415 under the Securities Act or any suc-
         cessor provision.  Issuer shall use its best efforts to cause
         each such registration statement to become effective and to
         remain effective for such period not in excess of 180 days from
         the day such registration statement first becomes effective as
         may be reasonably necessary to effect such sale or other dis-
         position.  Issuer shall also use its best efforts to qualify
         such shares or other securities under any applicable state
         securities laws.  Grantee agrees to use all reasonable efforts
         to cause, and to cause any underwriters or agents of any sale
         or other disposition to cause, any sale or other disposition
         pursuant to such registration statement to be effected on a
         widely distributed basis so that upon consummation thereof no
         purchaser or transferee shall own beneficially more than 2% of
         the then outstanding voting power of Issuer.  In the event that
         Grantee requests Issuer to file a registration statement fol-
         lowing the failure to obtain a required approval for an exer-
         cise of the Option as described in Section 3(e), the closing of
         the sale or other disposition of Issuer Common Stock or other
         securities pursuant to such registration statement shall occur
         substantially simultaneously with the exercise of the Option,
         and Grantee shall be entitled to cause the Option Shares to be
         issued directly to the underwriters or agents named in such
         registration statement.  The obligations of Issuer hereunder to
         file a registration statement and to maintain its effectiveness
         may be suspended for one or more periods of time that do not
         exceed 60 days in the aggregate for all such periods if the
         Board of Directors of Issuer shall have determined that the
         filing of such registration statement or the maintenance of its
         effectiveness would require disclosure of nonpublic information
         that would materially and adversely affect Issuer.  Any regis-
         tration effected under this Section 10 shall be at Issuer's ex-
         pense, except for underwriting discounts or commissions,
         brokers' fees and the fees and disbursements of Grantee's
         counsel related thereto.  Grantee shall provide all information
         reasonably requested by Issuer for inclusion in any registra-
         tion statement to be filed hereunder.  If requested by Grantee
         in connection with any such registration, Issuer shall become a
         party to any underwriting agreement relating to the sale of
         such shares or other securities, but only to the extent of
         obligating itself in respect of representations, warranties,
         covenants, indemnities, contribution and other agreements
         customarily included in such underwriting agreements for the
         issuer.  If, during the time periods referred to in the first
         sentence of this Section 10, Issuer effects a registration
         under the Securities Act of Issuer Common Stock for its own


                                       -12-<PAGE>







         account or for any other stockholders of Issuer (other than on
         Form S-4 or S-8, or any successor form), it shall allow Grantee
         the right to participate in such registration, and such par-
         ticipation shall not affect the obligation of Issuer to effect
         two registration statements for Grantee under this Section 10;
         provided that, if the managing underwriters of such offering
         advise Issuer in writing that in their opinion the number of
         shares of Issuer Common Stock requested to be included in such
         registration exceeds the number which can be sold in such of-
         fering, Issuer shall include the shares requested to be in-
         cluded therein by Grantee pro rata with the shares intended to
         be included therein by Issuer or other stockholders, taken as a
         single group.

                   (b)  If Issuer Common Stock or any other securities
         to be acquired upon exercise of the Option are then listed on a
         national or regional securities exchange or quoted on a na-
         tional or regional quotation system, Issuer, upon request of
         Grantee, shall use its best efforts to make any filings and
         obtain any approvals necessary in order to cause the Option
         Shares or other securities acquired upon exercise of the Option
         to be so listed or quoted.

                   11.  First Refusal.  At any time after the first oc-
         currence of a Triggering Event and prior to the later of (a)
         expiration of 24 months immediately following the first pur-
         chase of shares of Issuer Common Stock pursuant to the Option
         and (b) the termination of the Option pursuant to Section 3(a),
         if Grantee shall desire to sell, assign, transfer or otherwise
         dispose of all or any of the shares of Issuer Common Stock or
         other securities acquired by it pursuant to the Option, it
         shall give Issuer written notice of the proposed transaction
         (an "Offeror's Notice"), identifying the proposed transferee,
         accompanied by a copy of a binding offer to purchase such
         shares or other securities from such transferee and setting
         forth the terms of the proposed transaction.  An Offeror's
         Notice shall be deemed an offer by Grantee to Issuer, which may
         be accepted within 10 business days of the receipt of such
         Offeror's Notice, on the same terms and conditions and at the
         same price at which Grantee is proposing to transfer such
         shares or other securities to such transferee.  The purchase of
         any such shares or other securities by Issuer shall be settled
         within 10 business days of the date of the acceptance of the
         offer and the purchase price shall be paid to Grantee in im-
         mediately available funds; provided that, if prior notification
         to or approval of the Federal Reserve or any other Governmental
         Entity is required in connection with such purchase, Issuer
         shall promptly file the required notice or application for
         approval and shall expeditiously process the same (and Grantee
         shall cooperate with Issuer in the filing of any such notice or


                                       -13-<PAGE>







         application and the obtaining of any such approval) and the
         period of time that otherwise would run pursuant to this sen-
         tence shall run instead from the date on which, as the case may
         be, (i) any required notification period has expired or been
         terminated or (ii) such approval has been obtained and, in
         either event, any requisite waiting period shall have passed.
         In the event of the failure or refusal of Issuer to purchase
         all the shares or other securities covered by an Offeror's
         Notice or if the Federal Reserve or any other Governmental
         Entity disapproves Issuer's proposed purchase of such shares or
         other securities, Grantee may, within 60 days from the date of
         the Offeror's notice (subject to any necessary extension for
         regulatory notification, approval or waiting periods), sell
         all, but not less than all, of such shares or other securities
         to the proposed transferee at no less than the price specified,
         and on terms no more favorable than those specified, in the
         Offeror's Notice.  The requirements of this Section 11 shall
         not apply to (A) any disposition as a result of which the
         proposed transferee would own beneficially not more than 2% of
         the outstanding voting power of Issuer, (B) any disposition of
         Issuer Common Stock or other securities by a person to whom
         Grantee has assigned its rights under the Option with the
         consent of Issuer, (C) any sale by means of a public offering
         registered under the Securities Act in which steps are taken to
         reasonably assure that no purchaser will acquire securities
         representing more than 2% of the outstanding voting power of
         Issuer or (D) any transfer to Sub or to any other wholly owned
         subsidiary of Parent that agrees in writing to be bound by the
         terms hereof.

                   12.  Division of Option.  This Agreement (and the
         Option granted hereby) are exchangeable, without expense, at
         the option of Grantee, upon presentation and surrender of this
         Agreement at the principal office of Issuer, for other Agree-
         ments providing for Options of different denominations enti-
         tling the holder thereof to purchase in the aggregate the same
         number of shares of Issuer Common Stock purchasable hereunder.
         The terms "Agreement" and "Option" as used herein include any
         Stock Option Agreements and related Options for which this
         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
         Agreement, and (in the case of loss, theft, or destruction) of
         reasonably satisfactory indemnification, and upon surrender and
         cancellation of this Agreement, if mutilated, Issuer will ex-
         ecute and deliver a new Agreement of like tenor and date. Any
         such new Agreement executed and delivered shall constitute an
         additional contractual obligation on the part of Issuer,
         whether or not the Agreement so lost, stolen, destroyed, or
         mutilated shall at any time be enforceable by anyone.

                   13.  Assignment.  Neither this Agreement nor any of
         the rights, interests or obligations under this Agreement or
         the Option shall be assigned by any of the parties hereto
         (whether by operation of law or otherwise) without the prior
         written consent of the other parties, except that Grantee may
         assign in whole or in part its rights and obligations hereunder
         to Sub or to any other direct or indirect wholly owned sub-
         sidiary of Grantee without the consent of Issuer.  Subject to
         the preceding sentence, the terms and conditions of this
         Agreement shall inure to the benefit of and be binding upon the
         parties hereto and their respective successors and permitted
         assigns.

                   14.  Further Assurances.  Each party hereto will use
         its best efforts to make all filings with, and to obtain con-
         sent of, all third parties and governmental authorities nec-
         essary or advisable to the consummation of the transactions
         contemplated by this Agreement, including applying to the
         Federal Reserve under the BHC Act for approval to acquire the
         shares issuable hereunder.  In the event of any exercise of the
         Option by Grantee, Issuer, Grantee and Sub shall execute and
         deliver all other documents and instruments and take all other
         action that may be reasonably necessary or advisable in order
         to consummate the transactions provided for by such exercise.

                   15.  Specific Performance.  The parties hereto ac-
         knowledge that damages would be an inadequate remedy for a
         breach of this Agreement by either party hereto and that the
         obligations of the parties hereto shall be enforceable by ei-
         ther party hereto through specific performance, injunctive
         relief or other equitable relief.  This provision is without
         prejudice to any other rights that the parties hereto may have
         for any failure to perform this Agreement.

                   16.  Severability.  If any term, provision, covenant
         or restriction contained in this Agreement is held by a court
         or a Federal or state regulatory agency of competent juris-
         diction to be invalid, void or unenforceable, the remainder of
         the terms, provisions, covenants and restrictions contained in
         this 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 Grantee
         is not permitted to acquire, or Issuer is not permitted to
         repurchase pursuant to Section 8, the full number of Option
         Shares provided in Section 1(a) hereof (as adjusted pursuant to
         Section 6), it is the express intention of Issuer to allow
         Grantee to acquire or to require Issuer to repurchase such
         lesser number of Option Shares as may be permissible without
         any amendment or modification hereof.

                   17.  Notices.  All notices, requests, claims, demands
         and other communications hereunder shall be deemed to have been
         duly given when delivered in the manner and to the addresses
         specified in accordance with Section 8.02 of the Merger
         Agreement.

                   18.  Governing Law.  This Agreement shall be governed
         by and construed in accordance with the laws of the State of
         Michigan without regard to any applicable principles of con-
         flicts of laws.

                   19.  Counterparts.  This Agreement may be executed in
         one or more counterparts, all of which shall be considered one
         and the same agreement and shall become effective when one or
         more counterparts have been signed by each of the parties and
         delivered to the other parties.

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

                   21.  Limitation on Maximum Gain.  Notwithstanding
         anything to the contrary contained herein or in the Merger
         Agreement, the aggregate amount of gain realized by Grantee
         pursuant to this Stock Option Agreement from Issuer (or the
         Substitute Option Issuer), when added to the Termination Fee
         (as defined in Section 5.07(b) of the Merger Agreement), if
         any, received by Grantee pursuant to such Section 5.07(b),
         shall not in the aggregate exceed U.S. $75,000,000, and, in the
         event Grantee realizes gain in excess of such amount hereunder
         from Issuer (or the Substitute Option Issuer) or under the
         Termination Fee, Grantee hereby undertakes promptly to pay back
         to Issuer, by wire transfer of immediately available funds, the
         amount of such excess.

                   22.  Waiver and Amendment.  Any provision of this
         Agreement may be waived at any time by the party that is en-
         titled to the benefits of such provision.  This Agreement may
         not be modified, amended, altered or supplemented except upon
         the execution and delivery of a written agreement executed by
         the parties hereto.

                   23.  Entire Agreement; No Third-Party Beneficiaries.
         Except as otherwise expressly provided herein or in the Merger
         Agreement, this Agreement (and the Merger Agreement and the
         other documents and instruments referred to herein and therein)
         contains the entire agreement between the parties with respect


                                       -16-<PAGE>







         to the transactions contemplated hereunder and supersedes all
         prior arrangements or understandings with respect thereof,
         written or oral.  Nothing in this Agreement, expressed or im-
         plied, is intended to confer upon any party, other than the
         parties hereto, and their respective successors and permitted
         assigns, any rights, remedies, obligations or liabilities under
         or by reason of this Agreement, except as expressly provided
         herein.


                   IN WITNESS WHEREOF, each of the parties has caused
         this Agreement to be executed on its behalf by its officers
         thereunto duly authorized, all as of the day and year first
         above written.

                  [LETTERHEAD OF MICHIGAN NATIONAL CORPORATION]


                        NATIONAL AUSTRALIA BANK TO ACQUIRE
                        MICHIGAN NATIONAL FOR $1.5 BILLION

         Melbourne, Australia and Farmington Hills, Michigan, February
         5, 1995- - National Australia Bank Limited ("the National"), a
         transnational banking organization, headquartered in Melbourne,
         Australia, with assets of US$93 billion, equity of US$7.3
         billion and net income in the last fiscal year of US$1.3 bil-
         lion, and Michigan National Corporation (Nasdaq:  MNCO)
         ("Michigan National") today jointly announced the execution of
         a definitive agreement for the cash acquisition of Michigan
         National by the National.  Under the agreement, the holders of
         Michigan National common stock will receive $110.00 per share.
         The aggregate purchase price is approximately $1.5 billion.

                   Robert J. Mylod, Michigan National's chief executive
         officer, said, "Michigan National's Board of Directors and all
         of us in senior management are extremely pleased with the
         agreement.  We believe our partnership with a quality company
         like the National is in the best interests of our shareholders,
         our customers, our employees and the communities we serve.
         National Australia Bank is a superbly managed financial in-
         stitution with broad based banking operations in Australia,
         Great Britain, Ireland and New Zealand.  The entire Michigan
         National team is very enthusiastic about joining a partner with
         the balance sheet depth and strength of the National to help
         Michigan National's growth strategies."

                   Don Argus, the National's managing director and chief
         executive officer, stated, "The acquisition of Michigan
         National Corporation with its broad franchise in Michigan is
         the result of several years of reviewing the United States
