                                SCHEDULE 13D



     This statement is being filed with the Securities and Exchange Commission
(the "SEC") by ABN AMRO Holding N.V. ("ABN AMRO Holding"), ABN AMRO Bank N.V.
("ABN AMRO") and ABN AMRO North America, Inc. ("AANA") in accordance with the
requirements of Rule 13d-1 promulgated by the SEC under the Securities Exchange
Act of 1934, as amended (the "Exchange Act").  On November 21, 1996, AANA, a
Delaware corporation, Heitritz, Inc., a Delaware corporation and a wholly-owned
subsidiary of AANA ("Acquisition Co."), and Standard Federal Bancorporation,
Inc., a Michigan corporation ("Standard" or the "Issuer"), entered into an
Agreement and Plan of Merger (the "Merger Agreement"), pursuant to which it is
currently contemplated that AANA is to acquire Standard through the merger of
Acquisition Co. with and into Standard, subject to receipt of regulatory and
stockholder approval and satisfaction of certain other conditions.  In
connection with the Merger Agreement, AANA entered into an Option Agreement,
dated November 21, 1996 (the "Option Agreement"), with Standard.  The options
granted thereunder are exercisable following the occurrence of certain events
described therein and receipt of requisite regulatory approvals.  This
statement is being filed because, as described in Item 5 hereof, ABN AMRO
Holding, ABN AMRO and AANA may be deemed to have acquired "beneficial
ownership", as that term is defined in Rule 13d-3 promulgated by the SEC under
the Exchange Act, of certain shares of the Issuer as a result of AANA's having
entered into the Option Agreement.

     Any information herein relating to the Issuer, stockholders thereof, or
any other parties to the Option Agreement or the Merger Agreement (other than
ABN AMRO Holding, ABN AMRO and AANA or any subsidiaries or affiliates of any of
them) is based upon information set forth in such agreements or upon publicly
available information.

Item 1.    Security and Issuer.

     This statement relates to shares of common stock, no par value, of
Standard (the "Common Stock").  The name and address of the principal executive
office of Standard are as follows:

           Standard Federal Bancorporation, Inc.
           2600 West Big Beaver Road

Item 3.  Source and Amount of Funds or other Consideration.

         On November 21, 1996, AANA entered into the following:

         1.    the Option Agreement with Standard;

         2.    the Merger Agreement with Standard and Acquisition Co.,
               pursuant to which it is currently contemplated that AANA is to
               acquire Standard pursuant to a cash merger in which
               Acquisition Co. will be merged with and into Standard.

         The Option Agreement and the Merger Agreement are hereinafter
sometimes referred to collectively as the "Agreements."  Certain aspects of the
Agreements are summarized in this Schedule.  The summaries contained herein are
qualified by the actual terms of the Agreements, each of which is attached
hereto, and incorporated herein by this reference.  Copies of the Merger
Agreement and the Option Agreement are attached hereto as Exhibit A and Exhibit
B, respectively.

         All capitalized terms that are defined in the Agreements shall have
the same meanings when used herein, unless otherwise specified.

         Pursuant to the Merger Agreement, AANA and Standard have agreed that
AANA will acquire Standard through the merger of Acquisition Co. with and into
Standard, subject to receipt of regulatory and stockholder approvals and
satisfaction of certain other conditions, for U.S. $59.00 in cash per share of
Common Stock.

         Upon the terms of and subject to the conditions set forth in the
Option Agreement, Standard has granted to AANA an irrevocable and exclusive
option (the "Option") to purchase, after the occurrence of a Triggering Event
(a "Triggering Event") and subject to receipt of all necessary regulatory
approvals, an aggregate amount of up to 19.9% (up to 6,209,894 shares) of
authorized but unissued Common Stock at an exercise price of U.S $52.50 per
share.

         It is expected that the funds necessary to purchase the shares subject
to the Option following a Triggering Event would be generated from AANA's
internal funds.

Item 4.         Purpose of Transaction.

         AANA's purpose for entering into the Option Agreement is to facilitate
the acquisition of Standard pursuant to the Merger Agreement.  Pursuant to the
Option Agreement, AANA has the right to acquire up to 19.9% of authorized but
unissued Common Stock following the occurrence of a Triggering Event and
receipt of all necessary regulatory approvals.

         If the transactions contemplated by the Merger Agreement are
consummated, (1) AANA will, in effect, acquire all of the Common Stock; (2)
Acquisition Co., a wholly owned subsidiary of AANA, will be merged with and
into the Issuer; (3) the Common Stock would be eligible for termination of
registration pursuant to Section 12(g) of the Exchange Act and would cease to
be quoted on any inter-dealer quotation system; and (4) other similar actions
might be taken or changes may occur reflecting the transactions contemplated by
the Agreements.  The Agreements may impede the acquisition of control of the
Issuer by another person.


Item 5.         Interest in the Securities of the Issuer.

(a)             Option Agreement.  Pursuant to the Option Agreement, AANA has 
         the right to acquire up to 19.9% (up to 6,209,894 shares) (based upon
         the issued and outstanding stock of Standard as represented in the 
         Merger Agreement) of authorized but unissued shares of Common Stock 
         upon the occurrence of a Triggering Event.  The Option may be 
         exercised only after all necessary regulatory approvals are obtained.
         The Option Agreement shall terminate upon the first to occur of (i) the
         consummation of the transactions contemplated by the Merger Agreement,
         (ii) twenty-four (24) months after the occurrence of a Triggering
         Event, (iii) the termination of the Merger Agreement by reason of a
         wrongful termination thereof by AANA, (iv) the termination of the
         Merger Agreement by mutual agreement of Standard, AANA and Acquisition
         Co., (v) six (6) months after the termination of the Merger Agreement
         by Standard by reason of an uncured material breach thereof by AANA,
         pursuant to Section 7.1(d)(i) of the Merger Agreement, or (vi) twelve
         (12) months after termination of the Merger Agreement for any other
         reason.  Upon the occurrence of certain Triggering Events and the
         consummation of the transaction which is the subject of such
         Triggering Event, or if any Person other than AANA or an affiliate of
         AANA acquires beneficial ownership of 50% or more of then outstanding
         shares of the Common Stock, AANA may elect to receive a cash payment
         specified in the Option Agreement in lieu of exercising the Option.

                In the event that prior to termination of the Option Agreement, 
         Standard shall enter into an agreement with a Person other than AANA 
         or a subsidiary of AANA pursuant to which such Person or any affiliate 
         of such Person would acquire all or

         substantially all of the assets of Standard, or merge or consolidate,
         or enter into any similar transaction, with Standard and either
         Standard shall not be the continuing or surviving corporation of such
         merger or consolidation or similar transaction or Standard shall be
         the continuing or surviving corporation, but, in connection with the
         transaction, the then outstanding shares of Common Stock shall be
         changed into or exchanged for other securities of any other Person or
         cash or any other property or the then outstanding shares of Common
         Stock shall after such transaction represent less than 50% of the
         outstanding shares and share equivalents of the merged company, then
         the option relating to Common Stock shall, at the election of AANA, be
         converted into, or exchanged for, an option of the Acquiring
         Corporation (as defined in the Option Agreement) or any Person that
         controls the Acquiring Corporation.

                 ABN AMRO Holding, ABN AMRO and AANA may be deemed to have
         acquired beneficial ownership, as defined in Rule 13d-3 promulgated by
         the SEC under the Exchange Act, of the shares of Common Stock relating
         to the contractual arrangements described in the preceding paragraphs.
         Such persons may, from time to time, acquire shares of Common Stock in
         the open market or in private transactions.

(b)              Option Agreement.  AANA currently does not have the right to
         vote or to direct the vote, or to dispose or direct the disposition
         of, the shares of Common Stock subject to the Option Agreement.  AANA
         has the right, upon the occurrence of a Triggering Event and receipt
         of all necessary regulatory approvals, to acquire the shares subject
         to the Option.  If such shares were acquired by exercise of the
         Option, AANA would have the sole power to vote and dispose of such
         shares.  As ABN AMRO Holding may be deemed to control ABN AMRO and
         AANA, and ABN AMRO may be deemed to control AANA, ABN AMRO Holding and
         ABN AMRO may also be deemed to have the voting and dispositive powers
         described in the preceding two sentences.

(c)              To the best knowledge of ABN AMRO Holding, ABN AMRO and AANA,
         as reported herein, there has been no transaction in the Common Stock
         of the Issuer effected during the past sixty (60) days by the persons
         named in response to Item 5(a).

(d)              To the best knowledge of ABN AMRO Holding, ABN AMRO and AANA,
         no Person other than AANA has the power to direct the receipt of
         dividends from, or the proceeds from the sale of, the Option Shares
         described in Item 5(a), except that AANA may assign the Option
         Agreement to a wholly-owned subsidiary of AANA.  AANA has not
         assigned the Option Agreement.

Item 6.       Contracts, Arrangements, Understandings or Relationships with 
              Respect to Securities of the Issuer.

Agreements are contained in Items 3, 4 and 5.

                                  ARTICLE II

                       CONVERSION OF SHARES IN THE MERGER

     2.1 Terms of Merger.  Upon the Merger becoming effective:

         (a) At the Effective Time, each share of Company Common Stock issued
and outstanding immediately prior to the Effective Time of the Merger, other
than Company Common Stock owned by Purchaser or any Affiliate of Purchaser,
shall, ipso facto and without any action on the part of the holder thereof,
become and be converted into the right to receive the Merger Consideration. 
The certificates representing outstanding Company Common Stock shall, after the
Effective Time of the Merger, represent only the right to receive the Merger
Consideration from Purchaser.  Each holder of Company Common Stock, upon
surrender to the Exchange Agent, in proper form for cancellation, of the stock
certificate or certificates representing such Company Common Stock, shall be
entitled to receive a check from the Exchange Agent in an appropriate amount of
Merger Consideration for such shares.  Until so presented and surrendered in
exchange for the Merger Consideration, each certificate which represented
issued and outstanding Company Common Stock shall be deemed for all purposes to
evidence ownership of the Merger Consideration.  After the Effective Time,
there shall be no transfer on the stock transfer books of the Company of
Company Common Stock.  No interest shall accrue or be payable with respect to
the Merger Consideration.

         (b) Each share of Company Common Stock issued and owned of record by
Purchaser or any Affiliate of Purchaser on the Effective Time of the Merger
shall be cancelled and retired, and no securities shall be issuable and no cash
paid with respect thereto.

         (c) Each share of common stock of MergerSub issued and outstanding on
the Effective Time of the Merger shall, ipso facto and without any action on
the part of the holder thereof, continue as one share of the common stock of
the Surviving Corporation and all of such shares of common stock of the
Surviving Corporation shall be owned by Purchaser.  Outstanding certificates
representing shares of common stock of MergerSub shall be deemed to represent
an identical number of shares of common stock of the Surviving Corporation.

         (d) Each option granted under the Company Incentive Plans issued and
outstanding immediately prior to the Effective Time shall ipso facto and
without any action on the part of holders thereof, become and be converted into
the right to receive the difference between the Merger Consideration and the
applicable option exercise price.

     2.2 Payment for Shares.  At and from time to time after the Effective
Time, Purchaser shall make available or cause to be made available to the
Exchange Agent amounts sufficient in the aggregate to provide all funds
necessary for the Exchange Agent to make payments of the Merger Consideration
hereof to holders of the Company Common Stock issued and outstanding
immediately prior to the Effective Time.  As soon as practicable after the
Effective Time, Purchaser shall cause to be mailed to each person (or otherwise
to be delivered 

                                      8
<PAGE>   13

to each person, at such person's expense, who requests delivery) who
was, at the Effective Time, a holder of record of issued and outstanding Company
Common Stock, a letter of transmittal and instructions for use in effecting the
surrender of the Company Certificate(s) which, immediately prior to the
Effective Time, represented such shares.  Upon surrender to the Exchange Agent
of such certificates (or such documentation as is acceptable to and required by
the Exchange Agent with respect to lost certificates), together with such letter
of transmittal, duly executed and completed in accordance with the instructions
thereto, the Exchange Agent shall promptly cause to be paid to the Persons
entitled thereto a check in the amount to which such Persons are entitled, after
giving effect to any required tax withholdings.  If payment is to be made to a
Person other than the registered holder of the Company Certificate(s)
surrendered, it shall be a condition of such payment that the Company
Certificate(s) so surrendered shall be properly endorsed or otherwise in proper
form for transfer and that 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 the Company Certificate(s) surrendered or established
to the satisfaction of Purchaser or the Exchange Agent that such tax has been
paid or is not applicable. One Hundred Eighty (180) days following the Effective
Time, Purchaser shall be entitled to cause the Exchange Agent to deliver to it
any funds (including any interest received with respect thereto) made available
to the Exchange Agent which have not been disbursed to holders of certificates
formerly representing Company Common Stock outstanding at the Effective Time,
and thereafter such holders shall be entitled to look to Purchaser only as
general creditors thereof with respect to the cash payable upon due surrender of
their Company Certificates. Notwithstanding anything in this Section 2 or
elsewhere in this Agreement to the contrary, neither the Exchange Agent nor any
party hereto shall be liable to a former holder of Company Common Stock for any
cash delivered to a public official pursuant to applicable escheat or abandoned
property laws.  The Exchange Agent shall also deliver to Purchaser a certified
list of the names and addresses of all former registered holders of Company
Common Stock who have not then surrendered their Company Certificates to receive
the Merger Consideration to which they are entitled.  Except as otherwise
provided herein or in the Letter of Transmittal, Purchaser shall pay all charges
and expenses, including those of the Exchange Agent, in connection with the
payment of the Merger Consideration in exchange for Company Common Stock.

                                 ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Purchaser that each of the

<PAGE>   14

operate its properties and assets and to carry on its business as
presently conducted.  Neither the scope of the business of the Company nor the
location of any of its properties requires that it be licensed to do business
in any jurisdiction other than the State of Michigan and where the failure to
be so licensed or qualified will not have a Material Adverse Effect on the
Company. True and correct copies of the Company's Articles of Incorporation and
Bylaws, both as amended to the date hereof, have been delivered to Purchaser
prior to the date hereof.

            (b) The Bank is duly organized and existing as a federally-chartered

bank business. The Bank is a member of the FHLBI, and its deposits are insured
by the SAIF in the manner and to the extent provided by law.  The Bank has all
requisite corporate power and authority to own, lease and operate its
properties and assets and to carry on its business as presently conducted. True
and correct copies of the Bank's Charter and Bylaws, both as amended to the
date hereof, have been delivered to Purchaser prior to the date hereof.

            (c) Each Non-Bank Subsidiary is duly organized and existing as a
corporation under the laws of the state of its incorporation and is duly
qualified or licensed as a foreign corporation in each other state or
jurisdiction in which the ownership of property or the conduct of business
requires such licensing or qualification, except where the failure to be so
qualified or licensed would not have a Material Adverse Effect on the Company.
Each Non-Bank Subsidiary has all requisite corporate power and authority to
own, lease and operate its properties and assets and to carry on its business
as presently conducted.  True and correct copies of the Certificate of
Incorporation or Articles of Incorporation, as the case may be, and Bylaws of
each Non-Bank Subsidiary have been delivered to Purchaser prior to the
execution of this Agreement.

        3.2 Capitalization.

shares of Company Common Stock or any additional options, warrants or other
rights in or with respect to the unissued shares of Company Common Stock or any

to exercise voting rights in connection with the election of its directors
("Voting Debt"), nor does the Company have outstanding any options, warrants,

                                      10
<PAGE>   15

calls, rights, commitments or agreements of any kind obligating the Company or
any of its subsidiaries to issue or sell any Voting Debt.  There are no
outstanding contractual obligations of the Company or any of its subsidiaries
to repurchase, redeem or otherwise acquire any shares of its capital stock.

            (b) The authorized capital stock of the Bank consists of (i) 
50,000,000 shares of common stock, par value $1.00 per share ("Bank

the Bank Common Stock or any other securities convertible into such common
stock.

            (c) All of the outstanding shares of common stock of each Non-Bank
Subsidiary are validly issued, fully paid and nonassessable and are owned by
the Company or the Bank, free and clear of all liens and encumbrances.  There
are no outstanding options, warrants or other rights in or with respect to the
unissued shares of each Non-Bank Subsidiary's common stock nor any securities
convertible into such stock and no Non-Bank Subsidiary is obligated to issue
any additional shares of its common stock or any additional options, warrants
or other rights in or with respect to the unissued shares of its common stock
or any other securities convertible into such common stock.

        3.3 Subsidiaries.  Except for the Bank and the Non-Bank Subsidiaries,
and except as set forth on Schedule 3.3 to the Company's disclosure schedule
attached hereto and made a part hereof (together with all the other schedules,
the "Company Disclosure Schedule"), neither the Company nor the Bank owns or
holds, directly or indirectly, any equity interest in any Person that is not
readily marketable on a nationally recognized exchange or securities market.

        3.4 Company Financial Statements; Absence of Liabilities.
        
            (a) There have been delivered by the Company to Purchaser copies
of the Company Financial Statements.  The Company Financial Statements:
(i) fairly present the consolidated financial condition of the Company and its
subsidiaries as of the respective dates indicated and its consolidated results
of operations and the consolidated changes in its shareholders' equity and cash
flows for the respective periods indicated, except for the unaudited
consolidated financial statements of the Company and its subsidiaries, which
are subject to normal year-end adjustments; (ii) have been prepared in
accordance with GAAP; (iii) are based on the books and records of the Company
and its subsidiaries; and (iv) contain and reflect reserves for all material

<PAGE>   16
anticipated losses as of the date thereof, including, (but not limited
to) adequate reserves for reasonably anticipated loan and other losses.

         (b) The Company has no liabilities or obligations, either accrued or
contingent, which are material to it and which have not been reflected or
disclosed in the Company Financial Statements other than liabilities and
obligations incurred subsequent to December 31, 1995 in the ordinary course of

any basis for the assertion against it of any liability, obligation or claim
(including, without limitation, that of any regulatory authority) that might
result in or cause a material adverse change in the financial condition of the
Company which is not fairly reflected in the Company Financial Statements or in
the Company Regulatory Reports (including the accompanying financial statements
thereto) filed with the SEC subsequent to the filing of the Company's most
recent Annual Report on Form 10-K.

     3.5 Authority of the Company; No Violation.

         (a) The Company has all requisite corporate power and authority to
enter into this Agreement, and, subject to approval by the requisite majority
of its shareholders, to consummate the Merger and the transactions contemplated
hereby.  The execution and delivery by the Company of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action on the part of the Company (other

obligation of the Company, enforceable in accordance with its terms except as
such enforceability may be limited by (i) bankruptcy, insolvency, moratorium,
and other similar laws affecting creditors' rights generally, and (ii) general
principles of equity regardless of whether asserted in a proceeding in equity
or at law.  All of the conditions specified in the Company's Articles and
Bylaws and the MBCA have been met, and approval of this Agreement and the
Merger by the shareholders of the Company requires only the affirmative vote of
a majority of the outstanding shares of Company Common Stock entitled to vote
at the meeting of shareholders to be held pursuant to Section 5.7 hereof.

         (b) Except as set forth on Schedule 3.5 to the Company Disclosure
Schedule, neither the execution and delivery by the Company of this Agreement,
the consummation of the transactions contemplated herein, nor compliance by the
Company with any of the provisions hereof, will: (i) conflict with or result in
a breach of any provision of its Articles of Incorporation or Bylaws; (ii)
constitute a breach of or result in a default, or give rise to any rights of
termination, cancellation or acceleration, or any right to acquire any
securities, including without limitation, under the Rights Agreement (other
than the options currently outstanding under the Company Incentive Plans), or
assets, under any of the terms, conditions or provisions of any note, bond,
mortgage, indenture, franchise, license, permit, lease agreement or other
instrument or obligation to which the Company or any Company Subsidiary is a
party, by which the Company or any Company Subsidiary or any of their
respective properties or assets is bound, if in any such circumstances such
event could have a Material Adverse Effect 

                                      12

<PAGE>   17

on the Company or materially impair the Company's ability to perform its
obligations hereunder; or (iii) violate any order, writ, injunction, decree,
statute, rule or regulation applicable to the Company or any Company Subsidiary
or any of their respective properties or assets, the result of which could have
a Material Adverse Effect on the Company or materially impair the Company's
ability to perform its obligations hereunder.  Except as set forth on Schedule
3.5 to the Company Disclosure Schedule, no consent of, approval of, notice to or
filing with any governmental authority having jurisdiction over any aspect of
the business or assets of the Company, and no consent of, approval of or notice
to or filing with any other Person is required in connection with the execution
and delivery by the Company of this Agreement or the consummation by the Company
of the transactions contemplated hereby, except (A) the approval of this
Agreement and the transactions contemplated hereby by the shareholders of the
Company, and (B) such approvals of the Applicable Governmental Authorities and
any other governmental authorities having jurisdiction that are required by law
or regulation to consummate the transactions contemplated by this Agreement.

     3.6 Insurance.  The Company and each Company Subsidiary have in full force
and effect policies of insurance (including, without limitation, a blanket
bond, fire, third-party liability, use and occupancy), with respect to their
assets and business, against such casualties and contingencies and in such
amounts, types and forms as are appropriate for their business, operations,
properties and assets and usual and customary in the industry of which they are
a part.

     3.7 Books and Records.  The minute books of the Company and the Bank
contain true and accurate records of all meetings and actions taken by their
Boards of Directors, any committee thereof and their shareholders, and the
books and records of the Company and the Bank truly and accurately reflect
their respective businesses and affairs.

     3.8 Title to Assets.  The Company and each Company Subsidiary have good
and marketable title to all properties and assets, other than real property,
owned or stated to be owned by them, free and clear of all mortgages, liens,
encumbrances, pledges or charges of any kind or nature except for: (a)
encumbrances reflected in the Company Financial Statements or described in the
notes thereto; (b) liens for current taxes not yet due; (c) liens incurred in
the ordinary course of business; or (d) encumbrances, if any, which are not
substantial in character, amount or extent or which do not materially detract
from the value, or interfere with present use of the property subject thereto
or affected thereby, or otherwise materially impair the conduct of business of
the Company or the Company Subsidiaries.

     3.9 Real Properties.  Schedule 3.9 to the Company Disclosure Schedule
contains a list of real properties owned or leased by the Company or any
Company Subsidiary and contains, among other things, an accurate summary of all
material commitments which the Company or any Company Subsidiary have to
improve real estate owned by them.  True, correct and complete copies of all
leases in which the Company or any Company Subsidiary is either a lessor or a
lessee and which are listed or referred to in Schedule 3.9 have been delivered
to Purchaser prior to the date hereof.  The Company and each Company Subsidiary
have good and 

                                      13



<PAGE>   18
marketable title to all the real properties, and valid leasehold
interests in the leaseholds, described in Schedule 3.9 to the Company
Disclosure Schedule, free and clear of all mortgages, covenants, conditions,
restrictions, easements, liens, security interests, charges, claims,
assessments and encumbrances, except for: (a) rights of lessors, co-lessees or
sublessees in such matters which are reflected in the lease; (b) current taxes
not yet due and payable; (c) such imperfections of title and encumbrances, if
any, as do not materially detract from the value of or materially interfere
with the present use of such property; and (d) except as described in Schedule
3.9 to the Company Disclosure Schedule.

     3.10 Litigation.  Except as set forth on Schedule 3.10 to the Company
Disclosure Schedule, there is no private or governmental suit, claim, action or
proceeding (arbitral or otherwise) pending or, to the knowledge of the Company,
threatened against the Company or any Company Subsidiary which, if adversely
determined, may, in the reasonable belief of the Company, involve a payment by
the Company or any Company Subsidiary of more than $250,000 in excess of
available insurance coverage, or which involve a demand for equitable relief,
or against any of their respective directors or officers relating to the
performance of their duties in such capacities that may have a Material Adverse
Effect on the Company or on the transactions contemplated hereby.  Except as
set forth on Schedule 3.10 to the Company Disclosure Schedule, there are no
material judgments, decrees, stipulations or orders against the Company or any
Company Subsidiary enjoining them or any of their directors or officers in
respect of, or the effect of which is to prohibit, any business practice or the
acquisition of any property or the conduct of business in any area.  The
Company has delivered to Purchaser summary reports of its attorneys, dated on
or after January 1, 1996, on all pending litigation to which the Company, any
Company Subsidiary or any of their directors or officers is a party and which
names the Company, any Company Subsidiary or any of their directors or officers
as a defendant or cross-defendant and prays for damages or such other remedy or
remedies that, if sustained, could have a  Material Adverse Effect on the
Company or which could impair the ability of the Company to perform its
obligations hereunder.

     3.11 Taxes.  (a) The Company and each Company Subsidiary has filed all
federal and all material state and local tax returns required to be filed by it
(all such returns being accurate and complete in all material respects)
including, but not limited to, returns relating to income tax, franchise tax,
Michigan Single Business Tax, real and personal property tax, sales and use
tax, premium tax, excise tax and other tax returns of every character required
to be filed by it and has paid all taxes, together with any interest and
penalties owing in connection therewith, shown on such returns to be due in
respect of the periods covered by such returns, other than taxes which are
being contested in good faith and for which adequate reserves have been
established and reflected on the books and records of the Company and the
Company Subsidiaries.  Without limiting the foregoing, the Company and each
Company Subsidiary has filed all required payroll tax returns, has fulfilled
all tax withholding obligations and has paid over to the appropriate
governmental authorities the proper amounts with respect to the foregoing to
the extent such amounts are due.  The tax and audit positions taken by the
Company and each Company Subsidiary in connection with the tax returns
described in the preceding sentences were reasonable and asserted in good
faith. Adequate provision has been made in the books and 

                                      14
<PAGE>   19

records of the Company and each Company Subsidiary and, to the extent
required by GAAP, reflected in the Company Financial Statements, for all tax
liabilities, including interest or penalties, whether or not due and payable and
whether or not disputed, with respect to any and all federal, foreign, state,
local and other taxes of any kind or nature for the periods covered by the
Company Financial Statements and for all prior periods.  The IRS has examined,
or the statute of limitations has expired with respect to, the federal tax
returns of the Company and each Company Subsidiary (to the extent not filed as
part of a consolidated return of the Company) for all taxable years ending prior
to and including December 31, 1989.  Schedule 3.11 to the Company Disclosure
Schedule sets forth (a) the date or dates through which any federal, foreign,
state, local or other taxing authority has examined any other tax returns of the
Company; (b) a complete list of each year for which any federal, state or local
tax authority has obtained or has requested an extension of the statute of
limitations from the Company and lists each tax case of the Company currently
pending in audit, at the administrative appeals level or in litigation; and (c)
the date and issuing authority of each statutory notice of deficiency, notice of
proposed assessment and revenue agent's report issued to the Company within the
last 12 months. Schedule 3.11 to the Company Disclosure Schedule also identifies
any examination by taxing authorities of the federal, state or local tax returns
of the Company or its subsidiaries which have taken place since January 1, 1993,
and which have not been closed and completed without unresolved matters.  To the
knowledge of the Company, neither the IRS nor any foreign, state, local or other
taxing authority is now asserting or threatening to assert any deficiency or
claim for additional taxes (or interest thereon or penalties in connection
therewith) except as set forth in Schedule 3.11 to the Company Disclosure
Schedule.  All taxes which the Company or any Company Subsidiary has been
required to collect or withhold (other than backup withholdings pursuant to
Section 3406 of the Code) have been duly withheld or collected and, to the
extent required, have been paid to the proper taxing authority.  With respect to
backup withholdings, the Company and each Company Subsidiary have exercised the
degree of care required under Section 6724 of the Code to avoid the imposition
of any penalties for failure to obtain certified and correct taxpayer
identification numbers from payees or for failure to make backup withholdings.

        (b) Set forth on Schedule 3.11 to the Company Disclosure Schedule is a
complete list of all material tax elections made by the Company or any Company
Subsidiary on any income tax return filed during the past five years which have
the effect of deferring the realization of an item of income to a period after
the period for which such item of income was reported on the financial
statements of the Company or any Company Subsidiary, or accelerating an item of
deduction to a period prior to the period for which the corresponding item of
loss or expense was reported on the financial statements.  Neither the Company
nor any Company Subsidiary is a party to, has any liability under or is bound
by, any tax indemnity, tax sharing or tax allocation agreement other than as
described in Schedule 3.11 to the Company Disclosure Schedule.  There are no
liens for taxes (other than for current taxes not yet due and payable) upon the
assets of the Company or any Company Subsidiary.  The Company has never been a
member of an affiliated group of corporations, within the meaning of Section
1504 of the Code ("Affiliated Group"), other than as a common parent
corporation, and, except for those Non-Bank Subsidiaries, that have been
acquired by the Company, no Company Subsidiary has ever 

                                      15


<PAGE>   20

been a member of an Affiliated Group except where the Company was the
common parent of the Affiliated Group. To the knowledge of the Company, neither
the Company nor any Company Subsidiary has any liability for the taxes of any
person, corporation, association, partnership, limited liability company, or
other entity (other than the Company and the Company Subsidiaries) under
Treasury Regulation Section 1.1502-6 (or any similar provision of state, local,
or foreign law) as a transferee or successor, by contract or otherwise.

          (c) Neither the Company nor any Company Subsidiary has agreed to, or
to the best knowledge of the Company is required to, make any
adjustments under Section 481(a) of the Code by reason of a change in
accounting method or otherwise.  Neither the Company nor any Company Subsidiary
is a "United States Real Property Holding Corporation" as defined in Section
897 of the Code. Neither the Company nor any Company Subsidiary has filed a
consent under Section 341(f) of the Code.

     3.12 Compliance with Applicable Laws; Company Permits.  The Company and
each Company Subsidiary holds all permits, licenses, variances, exemptions,
orders and approvals of all governmental entities which are necessary for the
operation of the businesses of the Company and each Company Subsidiary (the
"Company Permits"), except for Company Permits the failure of which to hold
would not, individually or in the aggregate, have a Material Adverse Effect on
the Company.  All of the material Company Permits are listed on Schedule 3.12
to the Company Disclosure Schedule.  The Bank is an approved seller-servicer
for the Federal Home Loan Mortgage Corporation ("FHLMC"), the Government
National Mortgage Association ("GNMA") and the Federal National Mortgage
Association ("FNMA") and as such holds all necessary permits, authorizations or
approvals of FHLMC and FNMA necessary to carry on a mortgage banking business
with such governmental agencies.  The Bank is qualified to originate loans
insured by the Federal Housing Administration, the Department of Housing and
Urban Development and the Veteran's Administration.  The Company and the
Company Subsidiaries are in compliance in all material respects with the terms
of the Company Permits and all applicable laws and regulations, except for
possible violations which, individually or in the aggregate, would not have a
Material Adverse Effect on the Company.  No investigation by any governmental
entity with respect to the Company or any of the Company Subsidiaries is
pending or, to the knowledge of the Company, threatened, other than, in each
case, those the outcome of which will not have a Material Adverse Effect on the
Company.

     3.13 Performance of Obligations.  The Company and the Bank have performed
in all respects all material obligations required to be performed by them to
date and are not in default under or in breach of any term or provision of any
covenant, contract, lease, loan servicing agreement or arrangement, indenture
or any other covenant to which they are a party, are subject or are otherwise
bound, and no event has occurred which, with the giving of notice or the
passage of time or both, would constitute such default or breach, where such
default or breach would have a Material Adverse Effect on  Company.  Except for
loans and leases made by the Company or the Bank in the ordinary course of
business, to the knowledge of the Company, no party with whom the Company or
the Bank has an agreement which is of material importance to the business of
the Company or the Bank is in default thereunder.


                                      16

     3.14 Employees.  There are no controversies pending or threatened between,
or related to, the Company, the Bank or any Non-Bank Subsidiary and any of
their employees which could have consequences that may reasonably be expected
to have a Material Adverse Effect on the Company or impair the ability of the
Company to perform its obligations hereunder.  Except as disclosed in the
Company Financial Statements, all material sums due for employee compensation
and benefits have been duly and adequately paid or accrued on its books in
accordance with GAAP.  Neither the Company nor any Company Subsidiary is a
party to any collective bargaining agreement with respect to any of its
employees or any labor organization to which its employees or any of them
belong.

     3.15 Material Contracts.  (a)  Except as disclosed in the Company
Regulatory Reports or described on Schedule 3.15 to the Company Disclosure

                        (iii) any contract containing covenants which limit

required by law or applicable regulatory authority);

                        (iv) any other contract or agreement that would be

                        (vii) any material agreement or understanding which

3.15 to the Company Disclosure Schedule have been delivered to
Purchaser prior to the date hereof.

          3.16 Absence of Certain Changes.  Except as set forth in Schedule 3.16
to the Company Disclosure Schedule or the Company Regulatory Reports, since
December 31, 1995, the business of the Company and the Bank (inclusive of the
activities and operations of the Non-Bank Subsidiaries) has been conducted
diligently and only in the ordinary course, in the same manner as theretofore
conducted, and there has not been:

          (a) any change in the financial condition, results of operations,

payment by the Company or any Company Subsidiary of a bonus or other additional

disclosed on Schedule 3.15 to the Company Disclosure Schedule;

          (i) any sale, assignment or transfer of any assets in excess of

     3.17 Loans and Investments.  To the knowledge of the Company, all loans
and investments of the Company and each Company Subsidiary are legal and
enforceable in accordance with the terms thereof, except as may be limited by
any bankruptcy, insolvency, moratorium or other laws affecting creditors'
rights generally or by the exercise of judicial discretion.    Except as set

                                      19
<PAGE>   24
Subsidiary is licensed or authorized to use in their businesses,
including without limitation, any software licenses (collectively, the
"Intellectual Property").  With respect to each item of Intellectual Property
owned by the Company or any Company Subsidiary, the Company, or such Company
Subsidiary possesses all right, title and interest in and to the item, free and
clear of any lien, claim, royalty interest or encumbrance.  With respect to

complaint, claim, demand or notice alleging any interference, infringement,
misappropriation or violation with or of any intellectual property rights of a
third party (including any claims that the Company or any Company Subsidiary

     3.19 Company Benefit Plans.  (a)  Schedule 3.19(a)(1) to the Company
Disclosure Schedule contains a list of each compensation, consulting,
employment, termination or collective bargaining agreement, and each stock
option, stock purchase, stock appreciation right, recognition and retention,
life, health, accident or other insurance, bonus, deferred or incentive
compensation, severance or separation plan or any agreement providing any
payment or benefit resulting from a change in control, profit sharing,
retirement, or other employee benefit plan, practice, policy or arrangement of
any kind, oral or written, covering employees, former employees, directors or
former directors of the Company or any Company Subsidiary or their respective
beneficiaries, including, but not limited to, any employee benefit plans within
the meaning of Section 3(3) of ERISA, which the Company or any Company
Subsidiary maintains, to which the Company or any Company Subsidiary
contributes, or under which any employee, former employee, director or former
director of the Company or any Company Subsidiary is covered or has benefit
rights and pursuant to which any liability of the Company or any Company
Subsidiary exists or is reasonably likely to occur (the "Company Benefit
Plans"). Except as set forth on Schedule 3.19(a)(2) to the Company Disclosure
Schedule, neither the Company nor any Company Subsidiary maintains or has
entered into any Company Benefit Plan or other document, plan or agreement
which contains any change in control provisions which would cause an increase
or acceleration of benefits or benefit entitlements to employees or former
employees of the Company or any Company Subsidiary or their respective
beneficiaries, or other provisions which would cause an increase in the
liability to the Company or any Company Subsidiary or to Purchaser as a result
of the transactions contemplated by this Agreement or any related action
thereafter including, but not limited to, termination of employment or
directorship (a "Change in Control Benefit").  Neither the execution of this
Agreement or the Option Agreement constitutes a "change in control" for
purposes of any Company Benefit Plan or any Change in Control Benefits.  The
term "Company Benefit Plans" 

                                      20
<PAGE>   25


as used herein refers to all plans contemplated under the preceding
sentences of this Section 3.19, provided that the term "Plan" or "Plans" is used
in this Agreement for convenience only and does not constitute an acknowledgment
that a particular arrangement is an employee benefit plan within the meaning of
Section 3(3) of ERISA.  Except as disclosed in Schedule 3.19(a)(3) to the
Company Disclosure Schedule, no Company Benefit Plan is a multiemployer plan
within the meaning of Section 3(37) of ERISA and neither the Company nor any
Company has since December 31, 1990 maintained, sponsored or had an obligation
to contribute to any such multiemployer plan. Except as disclosed on Schedule
3.19(a)(4) to the Company Disclosure Schedule, neither the Company nor any
Company Subsidiary has been notified by any Applicable Governmental Authority
that any payments or other compensation paid or payable by the Company or any
Company Subsidiary under this Agreement, any Company Benefit Plan or otherwise,
to or for the benefit of any employee or director of the Company or any Company
Subsidiary, is not in compliance with all applicable rules, regulations and
bulletins promulgated by the Applicable Governmental Authorities and, to the
best knowledge of the Company or any Company Subsidiary, all such payments are
in compliance with all applicable rules, regulations and bulletins promulgated
by the Applicable Governmental Authorities.

         (b) Except as disclosed on Schedule 3.19(b) to the Company Disclosure
Schedule, each of the Company Benefit Plans that is intended to be a pension,
profit sharing, stock bonus, thrift, savings or employee stock ownership plan
that is qualified under Section 401(a) of the Code (the "Company Qualified
Plans") has been determined by the IRS to qualify under Section 401(a) of the
Code, or an application for determination of such qualification has been timely
made to the IRS prior to the end of the applicable remedial amendment period
under Section 401(b) of the Code (a copy of each such determination letter or
pending application has been provided to Purchaser by the Company), and, to the
knowledge of the Company, there exist no circumstances that may adversely
affect the qualified status of any such Company Qualified Plan.  All such
Company Qualified Plans established or maintained by Company or the Company
Subsidiaries or to which Company or the Company Subsidiaries contribute are in
compliance in all material respects with all applicable requirements of ERISA,
and are in compliance in all material respects with all applicable requirements
(including qualification and nondiscrimination requirements in effect as of the
Effective Time) of the Code for obtaining the tax benefits the Code thereupon
permits with respect to such Company Qualified Plans.  All accrued
contributions and other payments required to be made by the Company or any
Company Subsidiary to any Company Benefit Plan through September 30, 1996, have
been made or reserves adequate for such purposes as of  September 30, 1996,
have been set aside therefor and reflected in the Company Financial Statements
dated as of September 30, 1996.  Neither the Company nor any Company Subsidiary
is in material default in performing any of its respective contractual
obligations under any of the Company Benefit Plans or any related trust
agreement or insurance contract, and there are no material outstanding
liabilities of any such Plan other than liabilities for benefits to be paid to
participants in such plan and their beneficiaries in accordance with the terms
of such Plan.

                                      21



<PAGE>   26

        (c) There is no pending or, to the Company's knowledge, threatened
litigation or pending claim (other than benefit claims made in the ordinary
course) by or on behalf of or against any of the Company Benefit Plans (or with
respect to the administration of any of such Plans) now or heretofore
maintained by Company or any Company Subsidiary which alleges violations of
applicable state or federal law which are reasonably likely to result in a
liability on the part of the Company or any Company Subsidiary or any such
Plan, and to the Company's knowledge there is no basis for any such claim.

        (d) The Company and the Company Subsidiaries and all other persons
having fiduciary or other responsibilities or duties with respect to any
Company Benefit Plan are, and since the inception of each such plan have been,
in substantial compliance with, and each such plan is and has been operated in
substantial accordance with, its provisions and in substantial compliance with
the applicable laws, rules and regulations governing such plan, including,
without limitation, the rules and regulations promulgated by the United States
Department of Labor, the PBGC and the IRS under ERISA, the Code or any other
applicable law.  No "reportable event" (as defined in Section 4043(b) of ERISA)
has occurred with respect to any Company Benefit Plan.  No Company Benefit Plan
has engaged in or been a party to a "prohibited transaction" (as defined in
Section 406 of ERISA or Section 4975(c) of the Code) without an exemption
thereto under Section 408 of ERISA or 4975(d) of the Code.  All Company Benefit
Plans that are group health plans have been operated in compliance with the
group health plan continuation requirements of Section 4980B of the Code and
Section 601 of ERISA.

        (e) Neither the Company nor any Company Subsidiary has incurred, nor to
the Company's knowledge is the Company or any Company Subsidiary reasonably
likely to incur, any liability to the PBGC (except for payment of premiums)
under Title IV of ERISA in connection with any plan subject to the provisions
of Title IV of ERISA now or heretofore maintained or contributed to by the
Company, by any Company Subsidiary or by any other entity which is considered
one employer with the Company under ERISA or the Code (the "Company Pension
Plans").  No Company Pension Plan had an "accumulated funding deficiency" (as
defined in Section 302 of ERISA (whether or not waived)) as of the last day of
the most recently completed plan year.  Except as set forth on Schedule 3.19(e)
to the Company Disclosure Schedule, the fair market value of the assets of each
Company Pension Plan exceeds the present value of the "benefit liabilities" (as
defined in Section 4001(a)(16) of ERISA) under such Company Pension Plan as of
the end of the most recently completed plan year, calculated on the basis of
the actuarial assumptions used in the most recent valuation for such Company
Pension Plan prior to the date hereof, and there has been no material change in
the financial condition of any such Company Pension Plan since the last day of
the most recently completed plan year.  Neither the Company nor any Company
Subsidiary has provided or is required to provide security to any Company
Pension Plan pursuant to Section 401(a)(29) of the Code.

                                      22

<PAGE>   27

        (f) Except as disclosed on Schedule 3.19(f) to the Company Disclosure
Schedule, neither the Company nor any Company Subsidiary has made any payments,
or is a party to any agreement or any Company Benefit Plan that under any
circumstances could obligate it, any Company Subsidiary, or any successor of
either of them, to make any payment for which the deductibility for federal
income tax purposes by the Company, any Company Subsidiary or any successor to
the Company or any Company Subsidiary is or will be limited because of Section
162(m) or Section 280G of the Code.

        (g) The Company has delivered to Purchaser copies of (i) each Company
Benefit Plan (or a description with respect to any oral employee benefit plan,
practice, policy or arrangement) and all amendments thereto, (ii) current
summary plan descriptions of each Company Benefit Plan, (iii) each trust

Qualified Plan, (vi) the most recent available financial statements for each
Company Benefit Plan that has assets, (vii) the most recent actuarial report

plan merger subsequent to the date of such report, information substantially
describing the financial effects of such amendment or plan merger, (viii) the
most recent audited financial statements for each Company Benefit Plan for
which audited financial statements are required by ERISA, (ix) listing of
installment amounts payable from the FIRF Retirement Fund to any Company

agreements relating thereto, (xi) a listing of the shareholder value units
awarded under the Company Incentive Plans, showing the number of outstanding
shareholder value units credited to each participant, the measurement dates
applicable thereto, and the estimated payout value thereof as of the most
recent practicable date, and (xii) each officer or director for whom a deferred
compensation or supplemental retirement benefit is maintained, showing the
amounts due thereunder and the payment schedule thereof, and the respective
amounts accrued in the Company Financial Statements dated December 31, 1995 and
September 30, 1996.

        (h) Schedule 3.19(h) to the Company Disclosure Schedule describes any
obligation that the Company or any Company Subsidiary has to provide health or
welfare benefits to retirees or other former employees, directors or their
dependents (other than rights under Section 4980B of the Code or Section 601 of
ERISA), including information as to the number of retirees, other former
employees or directors and dependents entitled to such coverages and their
ages.

        (i) Schedules 3.19(i)(1) and (2) to the Company Disclosure Schedule
list: (1) each officer of the Company and any Company Subsidiary and each
director of Company and any Company Subsidiary who is eligible to receive a

<PAGE>   28
the estimated amount of each such Change in Control Benefit and the
basis of the calculation thereof, estimated compensation for 1996 based upon
compensation received to the date of this Agreement, the individual's rate of
compensation in effect on the date of this Agreement, the individual's
participation in any Company Benefit Plan (including the Company Incentive

on Form W-2 or Form 1099; and (2) each other employee of Company or the Company
Subsidiaries who may be eligible for a Change in Control Benefit, showing an
estimated amount of each such Change in Control Benefit and the basis of the
calculation thereof.

          (j) The Company and the Company Subsidiaries have filed or caused to 
be filed, and will continue to file or cause to be filed, in a timely manner all
filings pertaining to each Company Benefit Plan with the IRS, the PBGC and the
United States Department of Labor, as prescribed by the Code or ERISA, or
regulations issued thereunder.  All such filings, as amended, were and will be
complete and accurate in all material respects as of the dates of such filings.

          3.20 Regulatory Approvals.  To the knowledge of the Company, no fact 
or condition exists which the Company has reason to believe will prevent 
Purchaser from obtaining approval of the Applicable Governmental Authorities 
or any other applicable state or federal regulatory authority to consummate 
the Merger and the transactions contemplated herein.

          3.21 Company Regulatory Reports.  The Company has filed on a timely 
basis all proxy statements, reports and other documents required to be filed 
by it under the 1934 Act or HOLA after December 31, 1992 (collectively, the 
"Company Regulatory Reports"), and the Company has furnished Purchaser copies 
of its Annual Report on Form 10-K for the fiscal year ended December 31, 1995,
and all quarterly and periodic reports and proxy statements filed under the 
1934 Act by the Company after such date, each as filed with the SEC.  Each 
Company Regulatory Report was in compliance in all material respects with the
requirements of its respective report form and did not on the date of filing
contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

          3.22 Company Facilities.  To the knowledge of the Company, all
"alterations" (as such term is defined in the Americans with Disabilities Act
and the regulations issued thereunder (collectively, the "ADA")) to the
respective business of the Company, the Bank and each Non-Bank Subsidiary,

         3.25 Insider Interests.  No officer or director of the Company or the
Bank or any "affiliate" (as defined in Section 23A of the Federal Reserve Act 
(12 U.S.C. Section 371c)) of the Company, has any loan, credit or other 
contractual arrangement outstanding with the Company or the Bank which does 
not conform to applicable rules and regulations of the OTS and the Federal 
Reserve. No officer or director of the Company or any Affiliate of the Company
has any material interest in any property, real or personal, tangible or 
intangible, used in or pertaining to the business of the Company or any 
Company Subsidiary.

         3.26 Fairness Opinion.  The Board of Directors of the Company has 
received the written opinion of Merrill Lynch & Co., to the effect that, as of
the date of this Agreement, the Merger Consideration to be received by 
shareholders of the Company in the Merger is fair to such shareholders from a 
financial point of view.

         3.27 Brokers and Finders.  Except for the Company's agreement with 
Merrill Lynch & Co., a copy of which has been furnished to Purchaser prior to 
the execution hereof, the Company is not a party to any agreement with any 
broker, finder or investment banker relating to the transactions contemplated 
hereby, and neither the execution of this Agreement nor the consummation of the
transactions provided for herein will result in any liability to any broker or
finder.  Except for the fee payable to Merrill Lynch & Co., the Company agrees
to indemnify and hold Purchaser, MergerSub and their Affiliates harmless with
respect to any broker, finder or investment banker fee which any Person may
claim or assert arising from any express or implied agreement or engagement by
the Company or the Bank.

         3.28 Bylaws; State Takeover Statutes.  The Board of Directors of the
Company has approved the Merger, this Agreement and the Option Agreement and/or
has taken such other action, and such approval and/or other action is
sufficient to render inapplicable to the Merger, this Agreement, the Option
Agreement and the transactions contemplated by this Agreement and the Option
Agreement, the provisions of the Company's Bylaws and the provisions of
Chapters 7A and 7B of the MBCA.  Other than as described above, no other state
takeover statute or similar statute or regulation applies or purports to apply
to the Merger, this Agreement, the Option Agreement and the transactions
contemplated by this Agreement and the Option Agreement.

         3.29 Rights Agreement.  The Company and the Board of Directors have 
taken all necessary action to (i) render the Rights Agreement inapplicable with
respect to the Merger and the other transactions contemplated by this Agreement
and the Option Agreement and (ii) ensure that neither Purchaser nor MergerSub
nor any of their Affiliates will be deemed to be a "Acquiring Person" or an
"Adverse Person" (as such terms are defined in the Rights Agreement) and no
"Shares 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 Option Agreement or the consummation of the
transactions contemplated hereby and thereby.

corporate action on the part of Purchaser and MergerSub, and this Agreement has
been duly executed and delivered by Purchaser and MergerSub and constitutes the
valid and binding obligations of Purchaser and MergerSub, enforceable against
each of Purchaser and MergerSub in accordance with its terms except as such

other similar laws affecting creditors' rights generally, and (ii) general
principles of equity regardless of whether asserted in a proceeding in equity
or at law.

        (b) Neither the execution and delivery by Purchaser or MergerSub of

compliance by Purchaser or MergerSub with any of the provisions hereof, will:
(i) conflict with or result in a breach of any provision of its Certificate of
Incorporation or Bylaws; (ii) constitute a breach of or result in a default, or
give rise to any rights of termination, cancellation or acceleration under any

condition exists which Purchaser has reason to believe will prevent it or the
Company from obtaining any of the Regulatory Approvals.

        4.4 Litigation.  There is no private or governmental suit, claim,
action or proceeding pending or threatened, or which reasonably should be
expected to be commenced, against Purchaser, its subsidiaries or against any of

sufficient funds and capital to carry out its obligations under this Agreement.

        4.6 Proxy Statement.  None of the information to be supplied by

and as of the time of the meeting of the Company's shareholders in connection
therewith, and as amended or supplemented by Purchaser, will 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 contained therein
not misleading.

necessary in order to make the statements contained herein not misleading.

<PAGE>   36

related correspondence to the other parties.  Prior to filing each
application, registration statement or other document with the applicable
regulatory authority, each party will provide the other parties with a
reasonable opportunity to review and comment on the non-confidential portions of
each such application, registration statement or other document.  Each party
will use all reasonable efforts and will cooperate with the other party in
taking any other actions necessary to obtain such regulatory or other approvals

required hearings or proceedings.  Subject to the terms and conditions herein
provided, each party will use all reasonable efforts to take, or cause to be
taken, all actions and to do, or cause to be done, all things necessary, proper
or advisable to consummate and make effective as promptly as practicable the

all reasonable efforts and cooperate with each other to obtain any consents or
waivers from third parties that Purchaser reasonably deems to be necessary under
any contract or agreement to which the Company or any Company Subsidiary is a
party in order to prevent any breach or default from arising thereunder;
provided, however, that the failure to obtain any such consent or waiver shall
not constitute a breach of a covenant hereunder or a failure to satisfy any
condition precedent to either party's obligation to consummate the transactions
contemplated hereby.

          5.3 Securities Reports.  As soon as reasonably available, the Company
shall deliver to Purchaser complete copies of its Annual Report on Form 10-K,

required by applicable governmental authorities or by GAAP) and will present
fairly the consolidated financial condition of the Company and the Bank as of
the dates indicated and for the periods then ended.

          5.4 Acquisition Transaction.  The Company will not, and will cause the
Company Subsidiaries and its and the Company Subsidiaries' respective officers,
directors, employees, agents and Affiliates not to, directly or indirectly,
solicit, authorize, initiate or encourage submission of, any proposal, offer,
tender offer or exchange offer from any Person relating to any Acquisition
Transaction, or participate in any negotiations in connection with or in
furtherance of any Acquisition Transaction or permit any person other than
Purchaser and its representatives to have any access to the facilities of, or
furnish to any person other than Purchaser and its representatives any
non-public information with respect to, the Company or any of the Company
Subsidiaries in connection with or in furtherance of any of the foregoing. The
Company shall immediately cease and cause to be terminated any existing
activities, discussions, or negotiations with any parties (other than the
Purchaser) conducted heretofore with respect to any of the foregoing.  The
Company shall immediately provide to Purchaser telephone notice of any such
proposal or offer and shall promptly provide Purchaser with the name of the
party seeking to engage in such discussions or negotiations, or requesting such
information, and, after receipt of a written offer or proposal from such party,
copies of any written offers, proposals, agreements or other documents with
respect to such offer or proposal. Notwithstanding anything contained herein to
the contrary, nothing herein shall prohibit the 

                                      32
<PAGE>   37

Company, its directors and officers from taking any action otherwise
prohibited by this Section 5.4 if the Board of Directors of the Company
determines, upon receipt of a written opinion of its outside counsel, that it is
necessary to take such action in order to fulfill their fiduciary duties to
shareholders of the Company under the MBCA.

         5.5 Notification of Certain Matters.

         (a) Each party shall give prompt notice to the other parties of (i) the
occurrence or failure to occur of any event or the discovery of any
information, which occurrence, failure or discovery would be likely to cause
any representation or warranty on its part contained in this Agreement to be
untrue, inaccurate or incomplete after the date hereof or, in case of any
representation or warranty given as of a specific date, would be likely to
cause any such representation on its part contained in this Agreement to be
untrue, inaccurate or incomplete in any material respect as of such specific
date and (ii) any material failure of such party to comply with or satisfy any
covenant or agreement to be complied with or satisfied by it hereunder.

         (b) From and after the date hereof to the Effective Time and at and 
as of the Effective Time, the Company shall supplement or amend any of
its representations and warranties which apply to the period after the date
hereof by delivering monthly updates to the Company Disclosure Schedule
("Disclosure Schedule Updates") to Purchaser with respect to any matter
hereafter arising which, in the good faith judgment of the Company, would
render any such representation or warranty after the date of this Agreement
materially inaccurate or incomplete as a result of such matter arising. The
Disclosure Schedule Updates shall be provided to Purchaser on or before the
25th day of each calendar month.  Within twenty (20) days after receipt of any
Disclosure Schedule Update (or if cure is promptly commenced by the Company,
but is not effected within thirty (30) days after receipt of any Disclosure
Schedule Update (the "Cure Period")), Purchaser may exercise its right to
terminate this Agreement pursuant to Section 7.1(f) hereof, if the information
in such Disclosure Schedule Update together with the information in any or all
of the Disclosure Schedule Updates previously provided by the Company indicates
that the Company, in the good faith judgment of the Purchaser, has suffered or
is reasonably likely to suffer a Material Adverse Effect (i) which either has
not or cannot be cured within the Cure Period, or (ii) which does not result
primarily from changes in the general level of interest rates.

         5.6 Access to Information; Confidentiality.

         (a) Between the date hereof and the Effective Time, the Company will
afford, and will cause the Bank and each Non-Bank Subsidiary to afford, to the
officers, accountants, attorneys and authorized representatives of Purchaser
reasonable access during normal business hours to the banking offices,
personnel, advisors, consultants, properties, examination reports (subject to
regulatory approval), contracts, commitments, books and records of the Company,
the Bank and each Non-Bank Subsidiary, whether such documents are located on
the premises of the Company or elsewhere.  The Company shall furnish Purchaser
with all such statements 

                                      33

<PAGE>   38

(financial and otherwise), records, examination reports (to the extent
permitted or authorized by the OTS) and documents or copies thereof, and other
information concerning the business and affairs of the Company, the Bank and
each Non-Bank Subsidiary as Purchaser shall from time to time reasonably
request.  The Company further agrees to cause its accountants, attorneys and
such other persons as the parties shall mutually agree upon to fully cooperate
with Purchaser and its representatives in connection with the right of access
granted herein.

         (b) The Company will promptly furnish to Purchaser (i) a copy of each
material report filed by it with any governmental authority, including without
limitation, any federal, state or local taxing authority and any federal or
state bank regulatory or securities authority (each a "Company Report") during
the period after the date hereof and prior to the Effective Time, and (ii) all
other information concerning its business, properties and personnel as
Purchaser may reasonably request.  Each financial statement set forth in a
Company Report so filed and each financial statement provided by the Company to
Purchaser pursuant to the next following sentence, together with any notes or
schedules thereto, will present fairly in all material respects the information
purported to be set forth therein for the period specified therein (subject, in
the case of unaudited statements, to normal year-end adjustments and any other
adjustments described therein or the applicable principles with respect
thereto), in each case in accordance with GAAP during the periods involved or
applicable regulatory principles, as the case may be, in each case except as
otherwise provided herein, stated therein or in the notes thereto.  Throughout
the period after the date hereof and prior to the Effective Time, the Company
will provide to Purchaser, on or before the 25th day of each calendar month,
(i) the reports of management of the Company and Bank to the Board of Directors
of the Company and the Bank, respectively, for the most recently available
month, including to the extent available, delinquency schedules, addition to
loan loss reserves, and payroll reports, (ii) monthly financial statements
prepared by the Company for the preceding month, and (iii) a description of any
material changes with respect to the representations and warranties of the
Company or in any of the lists provided therewith.  Throughout the period after
the date hereof and prior to the Effective Time, the Company will cause one or
more of its designated representatives to confer on a regular and frequent
basis with representatives of Purchaser and to report the general status of the
ongoing operations of the Company and each Company Subsidiary.  During such
period, the Company promptly will notify Purchaser of any change in the
ordinary course of business or in the operation of the properties of the
Company or any Company Subsidiary or any breach by the Company of any
representation, warranty, covenant or agreement set forth in this Agreement,
and will keep Purchaser promptly and fully informed of such events.  During
such period, the Company will consult with Purchaser before taking any steps to
comply with suggestions made by any bank regulatory authority which could
reasonably be considered to be material to the Company.  The Company shall
allow a representative of Purchaser to attend as an observer the Board of
Directors', and committees thereof, meetings of the Company and the Bank.  The
Company shall give reasonable notice to Purchaser of any such meeting and, if

information obtained by Purchaser at these meetings shall be treated in
confidence as provided in this Section 5.6.

         (c) All information and documents to which Purchaser is given access
pursuant hereto shall be subject to the Confidentiality Agreement.  All
information furnished by the Company or any Company Subsidiary to Purchaser
pursuant hereto shall be treated as the sole property of the Company until
consummation of the Merger contemplated hereby and, if such Merger shall not
occur, Purchaser shall at the request of the Company, (i) return to the Company
or any Company Subsidiary or (ii) provide written confirmation of the
destruction of, all documents or other materials containing, reflecting or
referring to such information (and all copies thereof), shall use its best
efforts to keep confidential all such information, and shall not directly or
indirectly use such information for any competitive or other commercial
purpose. The obligation to keep such information confidential shall continue
for two (2) years from the date the proposed Merger is abandoned, but shall not
apply to (i) any information which was already in the possession of Purchaser
prior to disclosure thereof by the Company or any Company Subsidiary, (ii)
information which was then generally known to the public, information which
became known to the public through no fault of Purchaser or its agents, or
(iii) information disclosed in accordance with an order of any applicable
governmental authority or a court of competent jurisdiction.

duly call, give notice of, convene and hold a meeting of its shareholders, as
soon as practicable, but in no event later than forty-five (45) days after the
date the SEC clears the Proxy Statement, for the purpose of obtaining
shareholder approval of this Agreement and the Merger; provided, however, that
the Proxy Statement shall not be mailed to the holders of Company Common Stock
until Merrill Lynch & Co. has delivered to the Board of Directors of the
Company for inclusion in the Proxy Statement an opinion, dated the mailing
date, to the effect that the Merger Consideration is fair to the shareholders
of the Company from a financial point of view in standard industry form with
respect to transactions of this nature.  The Company will take all reasonable
steps necessary to submit the Proxy Statement to the SEC within thirty (30)
days after the date of this Agreement.  The Proxy Statement will satisfy all
requirements of the 1934 Act and the rules and regulations promulgated
thereunder and will include a unanimous recommendation by the Board of
Directors of the Company that the shareholders of the Company approve this
Agreement and the Merger.  Purchaser shall furnish such information concerning
Purchaser as is necessary in order to cause the Proxy Statement, insofar as it
relates to Purchaser, to be prepared in accordance with all applicable
requirements of the 1934 Act and the rules and regulations promulgated
thereunder.  Purchaser agrees promptly to advise the Company if at any time
prior to such Company shareholder meeting any information provided by Purchaser
in the Proxy Statement becomes incorrect or incomplete in any material respect,
and to provide to the Company the information needed to correct such inaccuracy
or omission.

        5.8 Employee Benefits.  The Company and Purchaser shall cooperate in
effecting the following treatment of the Company Benefit Plans, except as
mutually agreed upon by Purchaser and the Company prior to the Effective Time:

        (a) At the Effective Time, Purchaser or any subsidiary of Purchaser
shall, to the extent required by Purchaser, be substituted for the Company or
any Company Subsidiary as the sponsoring employer under those Company Benefit
Plans with respect to which Company or any Company Subsidiary is a sponsoring
employer immediately prior to the Effective Time, and shall assume and be
vested with all of the powers, rights, duties, obligations and liabilities
previously vested in Company or Company Subsidiary with respect to each such
plan.  Except as otherwise provided herein, each such plan and any Company
Benefit Plan sponsored by the Company or any Company Subsidiary shall be
continued in effect by Purchaser or any applicable subsidiary of Purchaser
after the Effective Time without a termination or discontinuance thereof as a
result of the Merger, subject to the power reserved to Purchaser or any
applicable subsidiary of Purchaser under each such plan to subsequently amend
or terminate the plan, which amendments or terminations shall be limited by and
otherwise comply with the terms of such plan and applicable law.  The Company,
each Company Subsidiary and Purchaser will use all reasonable efforts (i) to
effect said substitutions and assumptions, and such other actions contemplated
under this Agreement, and (ii) to amend such plans as to the extent necessary
to provide for said substitutions and assumptions, and such other actions
contemplated under this Agreement or the Benefits Letter.

        (b) After the Effective Time, at such times and to the extent set forth
in the Benefits Letter, Purchaser shall provide, or cause any applicable
subsidiary of Purchaser to provide, to each employee of Company and any Company
Subsidiary as of the Effective Time ("Company Employees") (i) the opportunity
to participate in each employee benefit plan and program maintained by
Purchaser for similarly situated employees of Purchaser and its subsidiaries
(the "Purchaser Benefit Plans"), (ii) credit for service with the Company, the
Bank or the Non-Bank Subsidiaries under the Purchaser Benefit Plans with
respect to the participation of such employees in such Purchaser Benefit Plans,
and (iii) waiver of waiting periods and preexisting condition exclusions under
the Purchaser Benefit Plans.  Nothing in the preceding sentence shall obligate
Purchaser to provide or cause to be provided any benefits duplicative to those
provided under any Company Benefit Plan continued pursuant to subparagraph (a)
above. Except as otherwise provided in this Agreement, the power of Purchaser
or Company or subsidiary of Purchaser to amend or terminate any benefit plan or
program, including any Company Benefit Plan, shall not be altered or affected,
but shall remain subject to any limitations provided in such plans or under
applicable law.

        (c) Purchaser agrees to honor or to cause an applicable Purchaser
subsidiary to honor certain other Company Benefit Plans, and to provide
severance benefits to eligible employees, as set forth in the Benefits Letter.

            (d) Nothing in this Section 5.8 or the Benefits Letter is intended,
nor shall it be construed, to confer any express or implied third party
beneficiary rights in any person including present or former employees of the
Company or any Company Subsidiary and any beneficiaries or dependents thereof.

        5.9 Company Incentive Plans.  The Company shall terminate the Company
Incentive Plans and cancel and terminate each outstanding option and
shareholder value unit ("SVU") thereunder, effective prior to the Effective
Time.  The Company shall use its best efforts to receive prior to the Effective
Time a cancellation agreement from each option holder and each SVU holder in
form and substance satisfactory to Purchaser ("Cancellation Agreements"),
acknowledging such cancellation and termination of options and SVUs.  The
Cancellation Agreements shall provide that in consideration for the
cancellation of such options and SVUs, the Company shall pay to such holders,
not more than two (2) days prior to the Effective Time, an amount (less any
applicable withholding and employment taxes) equal (i) in the case of options,
to the amount by which the Merger Consideration exceeds the exercise price per
share of Company Common Stock under the outstanding options held by such
holder, multiplied by the number of shares of Company Common Stock covered by
such options, and (ii) in the case of SVUs, to the amount determined in
accordance with Section 6.02 of the Company's 1995 Stock Option and Shareholder
Value Plan.  All options held by a person who does not deliver a Cancellation
Agreement to the Company prior to the Effective Time shall be converted as
provided in Section 2.1(d) hereof, and all SVUs held by a person who does not
deliver a Cancellation Agreement prior to the Effective Time shall be converted
into the right to receive cash in accordance with said Section 6.02, and
Purchaser shall pay to such holders, not more than two (2) days after the
receipt of a Cancellation Agreement, an amount (less any applicable withholding
and employment taxes) equal (x) in the case of options, to the amount by which
the Merger Consideration exceeds the exercise price per share of Company Common
Stock under the outstanding options held by such holder, multiplied by the
number of shares of Company Common Stock covered by such options and (y) in the
case of SVUs, to the amount determined in accordance with Section 6.02 of the
Company's 1995 Stock Option and Shareholder Value Plan.

        5.10  Indemnification.

              (a) Purchaser and MergerSub hereby agree that for six (6) years 
after the Effective Time, Purchaser and the Surviving Corporation shall
cause to be maintained in effect the Company's current policy of officers' and
directors' liability insurance with respect to actions and omissions occurring
on or prior to the Closing; provided, however, that the Surviving Corporation
may substitute therefor policies of at least the same coverage containing terms
and conditions which are no less advantageous to the covered persons and
provided that such substitution shall not result in any gaps or lapses in
coverage with respect to matters occurring on or prior to the Effective Time;
provided, further, that the Surviving Corporation shall not be required to pay
an annual premium in excess of 125% of the last annual premium paid by the
Company prior to the date hereof (which premium is disclosed in the Schedule
3.6 to the Company Disclosure Schedule) and if the Surviving Corporation is
unable to obtain the 

                                      37

<PAGE>   42

insurance required by this Section 5.10, it shall obtain as much
comparable insurance as possible for an annual premium equal to such maximum
amount.

          (b) Purchaser acknowledges the exculpation, indemnification,
advancement of expenses and like obligations of the Company and the Bank
contained in their Articles of Incorporation and Charter, respectively, and
ByLaws with respect to current and former directors, officers, employees and
agents ("Indemnified Persons") and hereby agrees, for six (6) years from and
after the Effective Time, to honor in accordance with their terms in effect on
the date hereof all such obligations.

          (c)  The provisions of this Section 5.10 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Person and
his or her heirs, beneficiaries and representatives.

     5.11 Bank Director Matters.  At  the Effective  Time,  Purchaser  agrees
to elect Mr. Thomas R. Ricketts as Chairman of the Board of the Bank as

parties hereto agrees to use its best efforts to take, or cause to be taken,
all action and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement.  In case at any time
after the Effective Time any further action is necessary or desirable to carry
out the purposes of this Agreement, the proper officers and directors of each
party to this Agreement shall take all such necessary action.

          (b) If necessary to expedite the Closing of the Merger and any other
transactions contemplated by this Agreement, the parties agree that each will
take or perform any additional reasonably necessary or advisable steps to
restructure the transactions contemplated hereby; provided, however, that any
such restructuring will not result in any change in the Merger Consideration.

     5.14 WARN Act.  The Company agrees that, if requested by Purchaser, it
shall, on behalf of Purchaser or any subsidiary of Purchaser, issue such
notices as are required under the Worker Adjustment and Retraining Notification
Act of 1988 (the "WARN Act") or any similarly applicable state or local law.
Such request by Purchaser shall be given in time to permit the Company to issue
notices  sufficiently in advance of any time of closing of such offices so that
Purchaser or any subsidiary of Purchaser shall not be liable under the WARN Act
for any penalty or payment in lieu of notice to any employee or governmental
entity.  Purchaser and the 

                                      38

Company shall cooperate in the preparation and giving of such notices,

not to exceed $.20 per share of Company Common Stock, if a regular dividend
declaration date shall be scheduled to occur during the twenty (20) day period
prior to Closing referred to in Section 1.2 hereof.

        7.2 Effect of Termination.

        (a) In the event of the termination of this Agreement as provided in

Purchaser or the Company except (i) for fraud or willful and material
breach of this Agreement and (ii) as set forth in this Section 7.2 and Section
8.2.

        (b) If this Agreement is terminated by the Board of Directors of

pay to Purchaser in immediately available funds not later than two business
days after demand therefor an amount equal to Ten Million Dollars ($10,000,000)
as reasonable reimbursement to Purchaser for all costs, fees and expenses
incurred or to be incurred by Purchaser in connection with this Agreement and

amounts actually received by Purchaser for the Option Shares or the Option (as
defined in the Option Agreement) prior to the making of a demand by Purchaser
for payment pursuant to this Section 7.2(b), including, without limitation, any
Repurchase Consideration paid under the Option Agreement from any Person,

any Purchase Price (as defined in the Option Agreement) actually paid for the
Option Shares by Purchaser under the Option Agreement (such amount being
referred to as the "Stock Option Consideration"), shall not exceed the Limit
(as defined in the Option Agreement), it being the intention of the parties
that if Purchaser has previously received Stock Option Consideration pursuant

Company, as the case may be, pursuant to Section 7.1(c)(i), Section 7.1
(c)(iii), Section 7.1(d)(i) or Section 7.1(e)(i) hereof, there shall be no
liability or obligation on the part of either Purchaser or the Company to the
other or on the part of any of their officers or directors, except pursuant to
Section 5.6, Section 7.2(b), Section 7.2(c) and Section 8.2 hereof and except
to the extent such termination results from the willful breach by a party
hereto of any of its representations, warranties, covenants or agreements
contained herein, or a wrongful termination hereof by Purchaser or the Company,
as the case may be.

                                OPTION AGREEMENT

     This OPTION AGREEMENT (the "Agreement") is entered into on November 21,
1996, by and between STANDARD FEDERAL BANCORPORATION, INC., a Michigan
corporation ("Standard"), and ABN AMRO NORTH AMERICA, INC., a Delaware
corporation ("AANA").

     AANA and Standard have entered into an Agreement and Plan of Merger (the
"Merger Agreement") providing, among other things, for the merger ("Merger") of
a wholly owned subsidiary of AANA with and into Standard with Standard as the
surviving corporation.  In connection with the Merger, each share of
outstanding common stock of Standard, no par value ("Common Stock"), would be
converted into the right to receive $59.00 per share in cash from AANA.  AANA
has expressly indicated to Standard that it would be unwilling to enter into
the Merger Agreement and consummate the transactions contemplated thereby
without the benefit of this Option Agreement.  In order to encourage AANA to
proceed with the Merger and to prepare required federal and state applications
for approvals from the Applicable Governmental Authorities and to incur
substantial expense in connection therewith, Standard has determined that it is
in its best interests to grant to AANA an option to purchase additional shares
of its authorized but unissued Common Stock.  Capitalized terms not otherwise
defined herein shall have the meanings given to them in the Merger Agreement.

     In consideration of the premises and the respective representations,
warranties, covenants and agreements set forth herein, and intending to be
legally bound hereby, Standard and AANA agree as follows:

     1. Grant of Option.  Subject to the terms and conditions set forth herein,
Standard hereby grants to AANA an option (the "Option") to purchase up to
6,209,894 fully paid and nonassessable shares (the "Option Shares") of Standard
Common Stock at a purchase price of $52.50 per share (such price, as adjusted
if applicable, the "Purchase Price").  Notwithstanding anything contained
herein or in the Merger Agreement to the contrary, the amount that AANA
(including any successor-in-interest, Affiliate or transferee) shall be
entitled to receive, whether as (a) consideration for the Option Shares or the
Option (including, without limitation, any payments in the form of Repurchase
Consideration) from any Person, including Standard (whether in a single
transaction or a series of transactions), less any Purchase Price actually paid
by AANA, or (b) costs, fees and expenses or other reimbursement amounts paid to
AANA pursuant to Section 7.2(b) of the Merger Agreement shall not exceed
$90,000,000 in the aggregate (the "Limit").  In the event that AANA receives or
is entitled to receive consideration and/or payments described in (a) and (b)
above in excess of the Limit, such excess amount shall be deemed to be held in
constructive trust by AANA for the benefit of Standard and shall be immediately
paid by AANA to Standard at the time and in the form such amount is received by
AANA.  Each certificate evidencing Option Shares issued to AANA upon exercise
of the Option shall bear a legend in form and substance acceptable to Standard
to the effect that such shares are subject to the foregoing restrictions.  The
foregoing restrictions with respect to the Limit 

<PAGE>   2

shall expire and be of no further force and effect on the day after the
second anniversary of the occurrence of a Triggering Event (as defined below).

     2. Exercise of Option.

     (a) The Option may be exercised in whole or in part prior to the
termination of this Agreement and after the occurrence of a Triggering Event,
as defined in Section 4 hereof.  In the event that AANA desires to exercise the
Option at any time, AANA shall notify Standard as to the number of shares of
Common Stock it wishes to purchase and a place and date, not less than 2
business days nor more than 10 business days after the date such notice is
given (the "Closing Date"), for the closing of such purchase; provided,
however, that notwithstanding the establishment of such Closing Date, the
consummation of the exercise of the Option may take place only after all
regulatory or supervisory agency approvals required by any applicable law, rule
or regulation shall have been obtained and each such approval shall have become
final. Standard shall fully cooperate with AANA in the filing of the required
notice or application for approval and the obtaining of any such approval.

     (b) On the Closing Date, AANA shall (i) pay to Standard, in immediately
available funds by wire transfer to a bank account designated by Standard, an
amount equal to the Purchase Price multiplied by the number of Option Shares to
be purchased on the Closing Date, and (ii) present and surrender this Agreement
to Standard at the address of Standard specified in Section 11(f) hereof.

     (c) On the Closing Date, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 2(b)
above, (i) Standard shall deliver to AANA a certificate or certificates
representing the Option Shares to be purchased at such Closing, which Option
Shares shall be free and clear of all liens, claims, charges and encumbrances
of any kind whatsoever, and, if the Option is exercised in part only, an
executed new agreement with the same terms as this Agreement evidencing the
right to purchase the balance of the Option Shares hereunder, and (ii) AANA
shall deliver to Standard a letter agreeing that AANA shall not offer to sell
or otherwise dispose of the Option Shares in violation of the provisions of
this Agreement.

     (d) Certificates for the Option Shares delivered at each Closing shall be
endorsed with a restrictive legend which shall read substantially as follows:

      THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO
      RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED, STATE
      SECURITIES LAWS AND PURSUANT TO THE TERMS OF AN OPTION AGREEMENT DATED
      NOVEMBER 22, 1996. A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE
      HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY Standard, INC. OF A WRITTEN
      REQUEST THEREFOR.

                                      2
<PAGE>   3

The above legend shall be removed by delivery of substitute certificate(s)
without the legend if AANA shall deliver to Standard a copy of a letter from
the staff of the Securities and Exchange Commission, or an opinion of counsel
in form and substance reasonably satisfactory to Standard and its counsel, to
the effect that the legend is not required for purposes of the Securities Act
of 1933, as amended (the "1933 Act").

     (e) Upon the giving of written notice of exercise by AANA to Standard and
the tender of the applicable purchase price in immediately available funds,
AANA shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Standard shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to AANA. Standard shall pay
all expenses, and any and all 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 2 in the name of AANA or its assignee,
transferee or designee.

     3. Termination of Option. The Option shall terminate and be of no further
force and effect upon the earliest to occur of: (i) the Effective Time (as
defined in the Merger Agreement), (ii) twenty-four (24) months after the
occurrence of a Triggering Event (as defined below), (iii) termination of the
Merger Agreement by reason of wrongful termination thereof by AANA or by mutual
agreement of the parties, (iv) six (6) months after the termination of the
Merger Agreement by Standard pursuant to Section 7.1(d)(i) thereof, or (v)
twelve (12) months after the termination of the Merger Agreement for any other
reason.

     4. Conditions to Exercise.  AANA may exercise the Option, in whole or in
part, at any time prior to its termination following the occurrence of a
Triggering Event.  The term "Triggering Event" shall mean the occurrence of any
of the following events:

           (a) if the Board of Directors of Standard shall withdraw its support
      of the Merger by resolution or by authorization of specific action
      inconsistent with consummation of the Merger, or if it fails to recommend
      approval of the Merger;

           (b) a Person (as defined by Section 13(d)(3)(e) of the 1934 Act),
      other than AANA or an Affiliate of AANA:

                 (i) acquires beneficial ownership (as such term is defined in
            Rule 13d-3 as promulgated under the Securities and Exchange Act of
            1934, as amended (the "Exchange Act")) of ten percent (10%) or more
            of the then outstanding Common Stock of Standard or securities
            representing, or the right or option to acquire beneficial
            ownership of, or to vote securities representing, ten percent (10%)
            or more of the then outstanding Common Stock of Standard, and after
            the occurrence of such acquisition the Board of Directors of
            Standard (A) recommends such acquisition to its stockholders for
            acceptance, (B) fails to undertake such acts as AANA reasonably
            requests to oppose such acquisition (provided that in so doing
            Standard does not incur significant legal expense), or 

                                      3
<PAGE>   4

            (C) fails to recommend or withdraws its approval of the Merger
            Agreement to the stockholders of Standard; or

                 (ii) enters into an agreement with Standard pursuant to which
            such Person or any affiliate of such Person would (A) merge or
            consolidate, or enter into any similar transaction, with Standard
            or (B) acquire all or substantially all of the assets of Standard;
            or

                 (iii) makes a bona fide proposal (a "Proposal") for any
            merger, consolidation or acquisition of all or substantially all
            the assets of Standard or other business combination involving
            Standard, and thereafter, but before such Proposal has been
            Publicly Withdrawn, Standard willfully commits any material breach
            of any covenant of the Merger Agreement and such breach (A) would
            entitle AANA to terminate the Merger Agreement without regard to
            the cure periods provided for therein, (B) is not cured and (C)
            would materially interfere with Standard's ability to consummate
            the Merger or materially reduce the value of the transaction to
            AANA.

The phrase "Publicly Withdrawn" for purposes of clause (iii) above shall mean
an unconditional bona fide withdrawal of the Proposal or a formal rejection of
such Proposal by Standard in writing.  Standard shall notify AANA promptly in
writing of the occurrence of any of the events set forth in paragraphs (b)(i),
(ii), or (iii) above, it being understood that the giving of such notice by
Standard shall not be a condition to the right of AANA to transfer or exercise
the Option.

     5. Representations and Warranties of Standard. Standard hereby represents
and warrants to AANA as follows:

     (a) Standard has all requisite corporate power and authority to enter into
this Agreement and, subject to any approvals referred to herein (including,
without limitation, the approval of FRB or OTS, if necessary), to consummate
the transactions contemplated hereby. The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby have
been duly authorized by all necessary corporate action on the part of Standard.
This Agreement has been duly executed and delivered by Standard.

     (b) Standard has taken all necessary corporate and other action to
authorize and reserve and to permit it to issue, and, at all times from the
date hereof until the obligation to deliver the Option Shares upon the exercise
of the Option terminates, will have reserved for issuance, upon exercise of the
Option, shares of Common Stock necessary for AANA to exercise the Option, and
Standard will take all necessary corporate action to authorize and reserve for
issuance all additional shares of Common Stock or other securities which may be
issued upon exercise of the Option. The Option Shares, including all additional
shares of Standard Common Stock or other securities which may be issuable
pursuant to Section 7 hereof, upon issuance pursuant hereto and payment
therefor, shall be duly and validly issued, fully paid and
                                      4
<PAGE>   5

nonassessable, and shall be delivered free and clear of all liens,
claims, charges and encumbrances of any kind or nature whatsoever, including
any preemptive rights of any stockholder of Standard.

     (c) The execution, delivery and performance of this Agreement does not or
will not, and the consummation by Standard of any of the transactions
contemplated hereby will not, constitute or result in (i) a breach or violation
of, or a default under, its certificate of incorporation or bylaws, or the
comparable governing instruments of any of its subsidiaries, or (ii) a breach
or violation of, or a default under, any agreement, lease, contract, note,
mortgage, indenture, arrangement or other obligation of it or any of its
subsidiaries (with or without the giving of notice, the lapse of time or both)
or under any law, rule, ordinance or regulation or judgment, decree, order,
award or governmental or nongovernmental permit or license to which it or any
of its subsidiaries is subject, that would, in any case referred to in this
clause (ii), give any other person the ability to prevent or enjoin Standard's
performance under this Agreement; provided, however, that Standard makes no
representations or warranties as to the enforceability or legality of this
Agreement and the Option granted hereby under the laws of the State of
Michigan.

     (d) Standard agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock;
(ii) that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other voluntary
act, avoid or seek to avoid the observance or performance of any of the
covenants, stipulations or conditions to be observed or performed hereunder by
Standard except pursuant to the Merger; (iii) promptly to take all action as
may from time to time be required (including (x) complying with all premerger
notification, reporting and waiting period requirements specified in 15 U.S.C.
section 18a and regulations promulgated thereunder and (y) in the event, under
the Home Owners' Loan Act, as amended, or the Change in Bank Control Act of
1978, as amended, or any state banking law, prior approval of or notice to the
OTS, or to any federal or state regulatory authority is necessary before the
Option may be exercised, cooperating fully with AANA in preparing such
applications or notices and providing such information to the OTS and the FRB
or such state regulatory authority as they may require) in order to permit AANA
to exercise the Option and Standard duly and effectively to issue shares of
Common Stock pursuant hereto; and (iv) promptly to take all action provided
herein to protect the rights of AANA against dilution on or prior to the
Closing Date.

     6. Representations and Warranties of AANA. AANA hereby represents and
warrants to Standard that:

     (a) AANA has all requisite corporate power and authority to enter into
this Agreement and, subject to any approvals or consents referred to herein, to
consummate the transactions contemplated hereby.  This Agreement has been duly
executed and delivered by AANA.

                                      5

<PAGE>   6

     (b) The Option is not being, and any Option Shares or other securities
acquired by AANA upon exercise of the Option will not be, acquired with a view
to the public distribution thereof and will not be transferred or otherwise
disposed of except in a transaction registered or exempt from registration
under the 1933 Act, as amended.

     7. Adjustment upon Changes in Capitalization; Repurchase of Option.

     (a) In the event of any change in Standard Common Stock by reason of a
stock dividend, stock split, split-up, recapitalization, combination, exchange
of shares or similar transaction, the type and number of shares or securities
subject to the Option, and the Purchase Price therefor, shall be adjusted
appropriately, and proper provision shall be made in the agreements governing
such transaction so that AANA shall receive, upon exercise of the Option, the
number and class of shares or other securities or property that AANA would have
received in respect of Standard Common Stock if the Option had been exercised
immediately prior to such event, or the record date therefor, as applicable.
If any additional shares of Standard Common Stock are issued after the date of
this Agreement (other than pursuant to an event described in the first sentence
of this Section 7(a)), the number of shares of Standard Common Stock subject to
the Option shall be adjusted so that, after such issuance, it, together with
any shares of Standard Common Stock previously issued pursuant hereto, equals
19.9% of the number of shares of Standard Common Stock then issued and
outstanding, without giving effect to any shares subject to or issued pursuant
to the Option.

     (b) If a Triggering Event described in Section 4(b)(ii) shall occur and
the transaction that is the subject of such Triggering Event is consummated, or
if any Person other than AANA or an Affiliate of AANA acquires beneficial
ownership of 50% or more of the then outstanding shares of Common Stock,
Standard, if requested by AANA, shall pay to AANA, in lieu of delivery of the
Option Shares an amount in cash equal to the Spread multiplied by the total
number of Option Shares for which the Option is exercisable (such aggregate
amount is referred to as the "Repurchase Consideration").

     (c) As used herein, "Spread" shall mean the excess, if any, over the
Purchase Price (as defined in Section 1) of the higher of (i) highest closing
price per share of Standard Common Stock as reported on the New York Stock
Exchange ("NYSE") within six months immediately preceding the date that AANA
requests cash in lieu of shares pursuant to this Section (the "Request Date"),
(ii) the price per share of Common Stock at which a tender offer or an exchange
offer therefor has been made, (iii) the price per share of Common Stock to be
paid to any third party pursuant to an agreement with Standard, or (iv) in the
event of a sale of all or a substantial portion of Standard's assets the sum of
the price paid in such sale for such assets and the current market value of the
remaining assets of Standard determined by a nationally recognized investment
banking firm mutually selected by AANA, on the one hand, and Standard, on the
other, divided by the number of shares of Common Stock of Standard outstanding
at the time of such sale.  In determining the Repurchase Consideration, the
value of consideration other than cash shall be determined by a nationally
recognized investment banking firm mutually selected by AANA, on the one hand,
and Standard on the other.

                                      6

<PAGE>   7

     (d) Upon exercise of its right to receive cash pursuant to this Section,
any and all obligations of AANA to make payment pursuant to Section 2(b) and
all obligations of Standard to deliver a certificate or certificates
representing shares of Common Stock pursuant to Section 2(b) shall be
terminated.  If AANA exercises its rights under this Section 7, Standard shall,
within 10 business days after the Request Date, pay the Repurchase
Consideration to AANA in immediately available funds, and AANA shall surrender
to Standard the Option. Notwithstanding the foregoing, to the extent that prior
notification to or approval of the FRB or other regulatory authority is
required in connection with the payment of all or any portion of the Repurchase
Consideration, AANA shall have the ongoing option to revoke its request for
repurchase pursuant to Section 7(b) or to require that Standard deliver from
time to time that portion of the Repurchase Consideration that it is not then
so prohibited from paying and promptly file the required notice or application
for approval and expeditiously process the same (and Standard shall cooperate
with AANA in the filing of any such notice or application and the obtaining of
any such approval).  If the FRB or any other regulatory authority disapproves
of any part of Standard's proposed repurchase pursuant to Section 7(b),
Standard shall promptly give notice of such fact to AANA and AANA shall have
the right to exercise the Option as to the number of Option Shares for which
the Option was exercisable at the Request Date.

     8. Registration Rights.

     (a) Upon the occurrence of a Triggering Event Standard shall, at the
request of AANA delivered at the time of and together with a written notice of
exercise in accordance with Section 2 hereof and on one occasion only, promptly
prepare, file and keep current a registration statement under the 1933 Act
covering any shares issued or issuable pursuant to this Option and shall use
its best efforts to cause such registration statement to become effective and
to remain effective for up to 180 days from the day such registration statement
first becomes effective or such shorter time as may be reasonably necessary in
order to permit the sale or other disposition of any shares of Common Stock
issued upon total or partial exercise of this Option in accordance with any
plan of disposition requested by AANA.  AANA will provide such information as
may be necessary for Standard's preparation of such a registration statement,
and any such information will not contain any statement which, at the time and
in light of the circumstances under which it is made, is false or misleading
with respect to any material fact nor will such information omit to state any
material facts with respect to AANA or its intended plan of disposition of
Option Shares.  The foregoing notwithstanding, if, at the time of any request
by AANA for registration of Option Shares as provided above, Standard is in
registration with respect to an underwritten public offering of shares of
Common Stock, and if in the good faith reasonable judgment of the managing
underwriter or managing underwriters, or, if none, the sole underwriter or
underwriters, of such offering the inclusion of AANA's Option or Option Shares
would interfere with the successful marketing of the shares of Common Stock
offered by Standard, the number of Option Shares otherwise to be covered in the
registration statement contemplated hereby may be reduced ("Underwriter
Reduction"); provided, however, that after any such required reduction, the
number of Option Shares to be included in such offering for the account of AANA
shall constitute at least 10% of the total number of shares to be sold by AANA
and Standard in the aggregate; provided, further, however, that if such
reduction occurs, 
                                      7

<PAGE>   8

then Standard shall file a registration statement for the balance as
promptly as practical and no reduction shall thereafter occur.  If requested by
AANA in connection with such registration, Standard shall become a party to any
underwriting agreement relating to the sale of such shares, but only to the
extent of obligating itself in respect of representations, warranties,
indemnities and other agreements customarily included in such underwriting
agreements for Standard.

     (b) If after the occurrence of a Triggering Event, Standard effects a
registration under the Securities Act of Standard Common Stock for its own
account or for any other stockholders of Standard (other than on Form S-4 or
Form S-8, or any successor forms or any form with respect to a dividend
reinvestment or similar plan), it shall allow AANA the right to participate in
such registration, and such participation shall not affect the obligation of
Standard to effect a registration statement for AANA under Section 8(a);
provided, however, that if the circumstances give rise to an Underwriter
Reduction as provided in 8(a) above then the procedure set forth in Section
8(a) governing the number of Option Shares to be included in such registration
shall apply.

     (c) In connection with any registration pursuant to this Section 8,
Standard and AANA shall provide each other and any underwriter of the offering
with customary representations, warranties, covenants, indemnification and
contribution in connection with such registration. Any registration statement
prepared and filed under this Section 8 and any sale covered thereby shall be
at Standard's expense except for underwriting discounts or commissions,
brokers' fees, taxes and the fees and disbursements of AANA's counsel related
thereto.

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

      (b) The following terms have the meanings indicated:

           (1) "Acquiring Corporation" shall mean (i) the continuing or
      surviving corporation of a consolidation or merger with Standard (if
      other than Standard), (ii) 

                                      8
<PAGE>   9


      Standard in a merger in which Standard is the continuing or surviving
      person, and (iii) the transferee of all or substantially all of 
      Standard's assets.

           (2) "Substitute Common Stock" shall mean the shares of capital stock
      (or similar equity interest) with the greatest voting power in respect of
      the election of directors (or other persons similarly responsible for
      direction of the business and affairs) of the issuer of the Substitute
      Option.

           (3) "Assigned Value" shall mean the highest of (i) the price per
      share of common stock at which a tender offer or exchange offer therefor
      has been made, (ii) the price per share of common stock to be paid by any
      third party pursuant to an agreement with Standard, or (iii) in the event
      of a sale of all or substantially all of Standard's assets, the sum of
      the price paid in such sale for such assets and the current market value
      of the remaining assets of Standard as determined by a nationally
      recognized investment banking firm selected by AANA divided by the number
      of shares of Common Stock of Standard outstanding at the time of such
      sale.  In determining the market/offer price, the value of consideration
      other than cash shall be determined by a nationally recognized investment
      banking firm selected by AANA.

           (4) "Average Price" shall mean the average closing price of a share
      of the Substitute Common Stock for the six months immediately preceding
      the consolidation, merger or sale in question, but in no event higher
      than the closing price of the shares of Substitute Common Stock on the
      day preceding such consolidation, merger or sale; provided, however, that
      if Standard 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 Standard or by any company which controls or is
      controlled by such person, as AANA may elect.

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

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


                                      9
<PAGE>   10

     (e) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.

     (f) Standard shall not enter into any transaction described in subsection
(a) of this Section 9 unless the Acquiring Corporation and any person that
controls the Acquiring Corporation assume in writing all the obligations of
Standard hereunder.

     10. Listing.  If Standard Common Stock to be acquired upon exercise of the
Option is then authorized for listing on the NYSE or on any other national
securities exchange or automated quotation system, Standard will promptly file
an application to authorize for listing the shares of Standard Common Stock to
be acquired upon exercise of the Option on the NYSE or such other securities
exchange or quotation system and will use its best efforts to obtain approval
of such listing as soon as practicable.

     11. Miscellaneous.

     (a) Expenses.  Except as otherwise provided in Section 8, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own financial consultants, investment
bankers, accountants and counsel.

     (b) Waiver and Amendment.  Any provision of this Agreement may be waived
at any time by the party that is entitled 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.

     (c) Entire Agreement; No Third-Party Beneficiary; Severability.  This
Agreement constitutes the entire agreement and supersedes all prior agreements
and understandings, both written and oral, between the parties with respect to
the subject matter hereof and is not intended to confer upon any person other
than the parties hereto any rights or remedies hereunder.  If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction or a federal or state regulatory agency to be invalid,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of 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 the Option does not permit AANA to
acquire, or does not require Standard to repurchase, the full number of shares
of Standard Common Stock as provided in Sections 2 and 7, it is the express
intention of Standard to allow AANA to acquire or to require Standard to
repurchase such lesser number of shares as may be permissible without any
amendment or modification hereof.

     (d) Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware without regard to any
applicable conflicts of law rules.
