AmeriFed Financial Corp.                                   [AMERIFED LETTERHEAD]
120 North Scott Street
Joliet, Illinois 60431-1291
Phone (815) 727-0370
    
 
   
                                                                November 4, 1994
    
Dear Stockholder:
 
   
     You are cordially invited to attend a Special Meeting of Stockholders (the
"Special Meeting") of AmeriFed Financial Corp. ("AmeriFed") which will be held
on Friday, December 9, 1994 at 3:00 p.m., local time, at the White Eagle Golf
Club, 3400 Club Drive, Naperville, Illinois 60564.
    
 
     At the Special Meeting, you will be asked to consider and vote upon a
proposal to approve an Agreement and Plan of Merger (the "Merger Agreement")
dated as of March 23, 1994 between NBD Bancorp, Inc. ("NBD"), NBD Illinois, Inc.
("NBD Illinois") and AmeriFed pursuant to which AmeriFed will be merged (the
"Merger") with and into NBD Illinois, a wholly owned subsidiary of NBD. Pursuant
to a related Agreement of Merger, it is intended that immediately following the
Merger, AmeriFed Bank, FSB ("AmeriFed Bank"), a federally chartered stock
savings bank and a wholly owned subsidiary of AmeriFed, will merge (the
"Subsidiary Bank Merger") with and into NBD Bank, an Illinois-chartered stock
commercial bank and a wholly-owned subsidiary of NBD Illinois. If the proposed
Merger is consummated, each share of Common Stock of AmeriFed will be converted
into and be exchangeable for the number of shares of Common Stock, $1.00 par
value per share, of NBD ("NBD Common Stock") equal to a fraction, the numerator
of which shall be equal to $45.00, and the denominator of which shall be equal
to the average closing price per share of NBD Common Stock as reported on the
New York Stock Exchange Composite Tape for the five trading days ending on the
fifth trading day prior to the Effective Date of Merger, as defined in the
Merger Agreement.
 
   
     The proposed Merger has been unanimously approved by the Boards of
Directors of both AmeriFed and NBD. The investment banking firm of The Chicago
Corporation has issued its written opinion to the AmeriFed Board of Directors to
the effect that the merger consideration is fair, from a financial point of
view, to AmeriFed's stockholders as of the October 24, 1994 date of its written
opinion. The written opinion of The Chicago Corporation is reproduced in full as
Appendix B to the Proxy Statement-Prospectus, and AmeriFed's stockholders are
urged to read such opinion.
    
 
     Consummation of the Merger is subject to certain conditions including, but
not limited to, approvals by the requisite vote of the stockholders of AmeriFed
and certain regulatory approvals.
 
     The enclosed Notice of Special Meeting and Proxy Statement-Prospectus
describe the terms of the Merger as well as other information relating to
AmeriFed and NBD. Please read these materials carefully.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR APPROVAL OF THE
PROPOSED MERGER AGREEMENT.
 
     IN ORDER TO ASSURE THAT YOUR SHARES WILL BE REPRESENTED AND VOTED AT THE
MEETING, PLEASE COMPLETE, SIGN AND DATE THE ENCLOSED PROXY, AND MAIL IT IN THE
RETURN ENVELOPE PROVIDED. A FAILURE TO VOTE WILL BE THE EQUIVALENT OF A VOTE
AGAINST THE MERGER AGREEMENT.
 
     Thank you for your attention to this important matter.
 
                                          Sincerely,
 
                                          [SIG]

     NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders of AmeriFed

     The Special Meeting is for the purpose of considering and voting upon the
following matters:
 
   
          1. To approve and adopt the Agreement and Plan of Merger dated as of
     March 23, 1994 (the "Merger Agreement") by and between NBD Bancorp, Inc.
     ("NBD"), NBD Illinois, Inc. ("NBD Illinois"), and AmeriFed and the
     transactions contemplated thereby, including the proposed merger (the
     "Merger") of AmeriFed with and into NBD Illinois, a wholly-owned subsidiary
     of NBD.
    
 
          2. To transact such other business as may properly come before the
     Special Meeting or any adjournments or postponements thereof including,
     without limitation, a motion to adjourn or postpone the Special Meeting to
     another time and/or place for the purpose of soliciting additional proxies
     in order to approve the Merger Agreement or otherwise.
 
   
     Pursuant to the AmeriFed By-laws, the Board of Directors has fixed November
1, 1994, as the record date for the determination of stockholders entitled to
notice of and to vote at the Special Meeting and at any adjournments or
postponements thereof. Only stockholders of record at the close of business on
that date will be entitled to vote at the Special Meeting or any adjournments or
postponements thereof. A list of AmeriFed stockholders entitled to vote at the
Special Meeting will be available for examination for any purpose germane to the
Special Meeting, during ordinary business hours, at the principal executive
offices of AmeriFed, located at 120 North Scott Street, Joliet, Illinois 60431,
for 10 days prior to the Special Meeting, and such list will also be available
at the Special Meeting. In the event there are not sufficient votes for a quorum
or to approve the Merger Agreement or otherwise at the time of the Special
Meeting, the Special Meeting may be adjourned in order to permit further
solicitation of proxies by AmeriFed.
    
 
   
     The affirmative vote of the holders of a majority of the outstanding shares
of AmeriFed Common Stock entitled to vote is required for approval of the Merger
Agreement.
    
 
     EACH STOCKHOLDER, WHETHER HE OR SHE PLANS TO ATTEND THE SPECIAL MEETING, IS
REQUESTED TO COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD IN THE
ENCLOSED POSTAGE-PAID ENVELOPE. ANY PROXY GIVEN BY THE STOCKHOLDER MAY BE
REVOKED AT ANY TIME BEFORE IT IS EXERCISED. A PROXY MAY BE REVOKED BY FILING
WITH THE SECRETARY OF AMERIFED A WRITTEN REVOCATION OR A DULY EXECUTED PROXY
BEARING A LATER DATE. ANY STOCKHOLDER PRESENT AT THE SPECIAL MEETING MAY REVOKE
HIS OR HER PROXY AND VOTE PERSONALLY ON EACH MATTER BROUGHT BEFORE THE SPECIAL
MEETING. HOWEVER, IF YOU ARE A STOCKHOLDER WHOSE SHARES ARE NOT REGISTERED IN
YOUR OWN NAME, YOU WILL NEED APPROPRIATE DOCUMENTATION FROM YOUR RECORDHOLDER TO
VOTE PERSONALLY AT THE SPECIAL MEETING.
 
                                          By Order of the Board of Directors

laws of Delaware in 1972. At June 30, 1994, NBD and its subsidiaries had total
assets of $45.2 billion, total deposits of $30.9 billion and stockholders'

NBD is NBD Bank, N.A., formerly named National Bank of Detroit, which was the
15th largest commercial bank in the United States based on total assets at June
30, 1994. NBD Bank, N.A. has applied to become a state chartered bank under
Michigan law and is awaiting approval. NBD has expanded significantly in recent

for additional acquisitions of financial institutions and related businesses.
The principal executive offices of NBD are located at 611 Woodward Avenue,
Detroit, Michigan 48226 and its telephone number is 313-225-1000.
 
     NBD Illinois was incorporated under the laws of Delaware in 1985 as a
wholly-owned subsidiary of NBD. Between 1987 and 1991 NBD acquired four bank
holding companies in Illinois and merged them into NBD Illinois, and in December
1992 merged 17 of the Illinois bank subsidiaries of those acquired companies
into NBD Bank, an Illinois-chartered commercial bank and wholly-owned subsidiary
of NBD Illinois. At June 30, 1994, NBD Illinois and its subsidiaries had total

     AmeriFed, a registered savings and loan holding company, was incorporated
under the laws of Delaware in 1991 for the purpose of acquiring all of the
capital of AmeriFed Bank, formerly named AmeriFed Federal Savings Bank, pursuant
to a conversion of AmeriFed Bank from a federally chartered mutual savings bank
to a federally chartered stock savings bank. AmeriFed Bank was organized in 1934
as the Joliet Federal Savings and Loan Association, and in 1986 converted to a
federal mutual savings bank and changed its name to AmeriFed Federal Savings
Bank. On June 1, 1993, AmeriFed Bank adopted its current name. AmeriFed Bank's
principal business has been and continues to be attracting retail deposits from
the general public and investing those deposits, together with funds generated
from operations and borrowings, primarily in one-to four-family residential
mortgage loans and, to a lesser extent, in multi-family residential mortgage
loans, construction and land loans, commercial real estate loans, home equity
and other consumer loans, commercial
    
 
                                        4

business loans, mortgage-backed securities, U.S. Treasury and Government agency
securities and other marketable securities. AmeriFed Bank also has a
wholly-owned subsidiary, AmeriFed Financial Services, Inc., which offers
insurance to AmeriFed Bank's customers. At June 30, 1994, AmeriFed and its
subsidiaries had total assets of $896.7 million, total deposits of $781.5
million and stockholders' equity of $91.9 million. Based on the most recent

southwest quadrant of the Chicago metropolitan area. The principal executive
offices of AmeriFed and AmeriFed Bank are located at 120 North Scott Street,
Joliet, Illinois 60431 and its telephone number is 815-727-0370.
    
 
THE MEETING
 
     The Special Meeting will be held on Friday, December 9, 1994 at 3:00 p.m.,
local time, at the White Eagle Golf Club, 3400 Club Drive, Naperville, Illinois
60564. At the Special Meeting, the stockholders of AmeriFed will be asked to
approve the Merger Agreement. See "MEETING INFORMATION -- Purpose." Only holders
of record of AmeriFed Common Stock at the close of business on November 1, 1994
(the "Record Date") will be entitled to vote at the Special Meeting. On the
Record Date, there were outstanding and entitled to vote 3,220,333 shares of
AmeriFed Common Stock. Each share of AmeriFed Common Stock is entitled to one
vote, except as described under "MEETING INFORMATION -- Voting Rights and Record
Date." On the Record Date, the directors and executive officers of AmeriFed and
their affiliates beneficially owned approximately 459,356 shares, or 14.3% of
the outstanding shares of AmeriFed Common Stock (excluding currently exercisable
options). An unrelated corporate trustee of the AmeriFed Federal Savings Bank
Employee Stock Ownership Plan and Trust ("ESOP") beneficially owned 224,702
shares of AmeriFed Common Stock on the Record Date (constituting approximately
6.98% of the outstanding shares). Pursuant to the terms of the ESOP, shares held
by the ESOP that are allocated to the accounts of the ESOP participants shall be
voted by the ESOP trustee as directed by such participants so long as such vote
is in accordance with the provisions of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"). Shares held by the ESOP that are currently
unallocated shall be voted by the ESOP trustee proportionate to the directions
given by ESOP participants with respect to allocated shares. The affirmative
vote of the holders of a majority of the outstanding shares of AmeriFed Common
Stock entitled to vote is required to approve the Merger Agreement. See "MEETING
INFORMATION -- Voting Rights and Record Date."
 
THE PROPOSED MERGER
 
     On March 23, 1994, AmeriFed, NBD Illinois and NBD entered into the
Agreements, which provide for the merger of AmeriFed into NBD Illinois. The
Merger Agreement sets forth the terms upon which the Merger, if consummated,
will be effected. The Reorganization Agreement sets forth various
representations, warranties and covenants of the parties relating to the
consummation of the Merger as well as the conditions which must be satisfied for
the Merger to be completed. See "PROPOSED MERGER -- Conditions to the Merger."
Although the Merger Agreement and the Reorganization Agreement relate to the
same transaction, separate agreements are being used because the former relates
primarily to the Merger itself, whereas the latter establishes the respective
obligations of the parties with respect to the Merger. The terms of the Option
Agreement are described under "Stock Option Agreement." The Merger Agreement is
attached to this Proxy Statement-Prospectus as Appendix A. A COPY OF THE
REORGANIZATION AGREEMENT AND OPTION AGREEMENT WILL BE PROVIDED WITHOUT CHARGE TO
ANY PERSON TO WHOM THIS PROXY STATEMENT-PROSPECTUS IS DELIVERED UPON WRITTEN
REQUEST TO ROBERT BIEDRON, EXECUTIVE VICE PRESIDENT AND SECRETARY OF AMERIFED,
OR DANIEL T. LIS, SENIOR VICE PRESIDENT AND SECRETARY OF NBD, AT THEIR
RESPECTIVE ADDRESSES INDICATED UNDER "AVAILABLE INFORMATION".
 
     On August 22, 1994, NBD Bank and AmeriFed Bank entered into an Agreement of
Merger pursuant to which AmeriFed Bank would be merged (the "Subsidiary Bank
Merger") into NBD Bank immediately following the Merger of AmeriFed into NBD
Illinois. As a result of the Subsidiary Bank Merger, the AmeriFed Bank assets
(including branch facilities and customer loans), liabilities (including
deposits) and
 
                                        5
<PAGE>   11
 
employees will immediately constitute a new Southwest Regional Banking Center of
NBD Bank at the date of the parent company Merger.
 
MERGER CONSIDERATION
 
     Upon consummation of the Merger, each outstanding share of AmeriFed Common
Stock (except for shares owned by NBD, NBD Illinois or AmeriFed) will be
automatically converted into a number of whole shares of NBD Common Stock equal
to a fraction, the numerator of which shall be equal to $45.00, and the
denominator of which shall be equal to the average closing price per share of
NBD Common Stock as reported on the NYSE Composite Tape for the five trading
days ending on the fifth trading day prior to the Effective Date of Merger, as
defined below. Cash will be paid in lieu of the fractional shares of NBD Common
Stock. See "PROPOSED MERGER -- Consideration for Shares."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     AmeriFed, through its financial advisor, The Chicago Corporation solicited
and received indications of interest concerning the acquisition of AmeriFed from
NBD and other financial institution holding companies. After consulting with The
Chicago Corporation and legal counsel, AmeriFed negotiated the proposed
Agreements with NBD. Following an in-depth analysis, review and discussion of
the Agreements by and among The Chicago Corporation, AmeriFed's legal counsel
and its Board of Directors, including The Chicago Corporation's advice that the
consideration to be received is fair, from a financial point of view, to holders
of AmeriFed Common Stock, the Board of Directors of AmeriFed unanimously voted
to accept the Agreements proposed by NBD. The AmeriFed Board believes that the
Merger will provide AmeriFed's stockholders with increased value and liquidity
for their stock and will provide its customers with expanded services and
products. The AmeriFed Board recommends that AmeriFed's stockholders vote FOR
approval of the Merger Agreement.
 
     For additional details regarding the recommendation of the AmeriFed Board,
see "PROPOSED MERGER -- Background of the Merger" and "-- Reasons for the
Merger."
 
OPINION OF FINANCIAL ADVISOR
 
     The Chicago Corporation, AmeriFed's financial advisor, has rendered its
written opinion to the AmeriFed Board that the consideration to be received by
AmeriFed stockholders pursuant to the Merger is fair, from a financial point of
view, to AmeriFed's stockholders.
 
   
     For information on the procedures followed, assumptions made, matters
considered in and qualifications of the review undertaken, and other matters in
connection with rendering the opinion by The Chicago Corporation, see "PROPOSED
MERGER -- Opinion of Financial Advisor to AmeriFed" and the opinion of The
Chicago Corporation attached as Appendix B to this Proxy Statement-Prospectus
which should be read carefully by AmeriFed stockholders.
    
 
STOCK OPTION AGREEMENT
 
   
     At the time of execution of the Agreements, AmeriFed and NBD entered into a
Stock Option Agreement dated as of March 23, 1994 (the "Option Agreement")
pursuant to which AmeriFed granted an option to NBD to purchase up to an
aggregate of 610,578 shares of AmeriFed Common Stock, or approximately 19.9% of
the then outstanding AmeriFed Common Stock, at a price per share of $32.75 (the
"Option"), exercisable only upon the happening of certain events. In addition,
the Option is exercisable only if NBD has fully complied with the terms of the
Agreements at the time of exercise. Depending on the number of shares purchased,
exercise of the Option may be subject to the prior approval of certain
government regulatory authorities. The Option Agreement is intended to make it
more difficult for another party to acquire AmeriFed, thereby increasing the
likelihood that the Merger will occur. See "PROPOSED MERGER -- Stock Option
Agreement."
    
 
                                        6
<PAGE>   12
 
EFFECTIVE DATE OF MERGER
 
   
     The Merger will be consummated at the close of business on the date
specified in a Certificate of Merger filed in accordance with the Delaware
General Corporation Law. The date on which the Merger will be consummated is
referred to herein as the "Effective Date of Merger". It is anticipated that if
the stockholders of AmeriFed approve the Merger Agreement at the Special Meeting
and the approvals of all requisite government regulatory authorities are
obtained, the Effective Date of Merger will be early in the first quarter of the
calendar year 1995, provided that the Agreements are not terminated prior to
such date. See "PROPOSED MERGER -- Effective Date of Merger" and "-- Conditions
to the Merger."
    
 
CONDITIONS TO THE MERGER AND TERMINATION
 
   
     Consummation of the Merger is subject to the satisfaction or waiver of
various conditions, including among other things, the approval of the Merger
Agreement by the stockholders of AmeriFed, approval of the Merger by all
requisite government regulatory authorities without any conditions which in the
reasonable opinion of NBD or AmeriFed are materially adverse, the receipt by
AmeriFed of an opinion of Muldoon, Murphy & Faucette that the Merger will
constitute a reorganization for Federal income tax purposes, and satisfaction of
various other conditions specified in the Reorganization Agreement. Applications
for prior approval of the Merger and/or the Subsidiary Bank Merger have been
submitted to the Office of Thrift Supervision, the Federal Deposit Insurance
Corporation, the Federal Reserve Bank of Chicago, and the Illinois Commissioner
of Banks and Trust Companies. While some regulatory approvals including The
Federal Deposit Insurance Corporation and the Federal Reserve Bank of Chicago
have been received, there can be no assurance that all of these regulatory
authorities will approve or take other required action with respect to the
Merger or as to the date of such approvals or actions. See "PROPOSED MERGER --
Conditions to the Merger" and "-- Regulatory Matters".
    
 
     The Merger may be terminated notwithstanding stockholder approval if
certain specified events occur. For instance, either AmeriFed or NBD may
terminate the Agreements if the Merger has not been consummated by March 31,
1995 or if any requisite government regulatory authority shall refuse to approve
the Merger or shall condition an approval in a manner not reasonably
satisfactory to NBD.  See "PROPOSED MERGER -- Termination, Amendment and
Waiver."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
   
     Certain members of AmeriFed's management and the AmeriFed Board may be
deemed to have certain interests in the Merger that are in addition to their
interests as stockholders generally. AmeriFed and AmeriFed Bank maintain
employment agreements and/or special termination agreements with its executive
officers which provide for certain payments and benefits in the event such
officers are terminated in the context of a change in control such as the
Merger. In addition, the Merger will result in the acceleration of vesting of
certain option and stock awards under AmeriFed's employee stock award plans.
Finally, the Reorganization Agreement provides that NBD will indemnify the
AmeriFed Board and management against certain liabilities for a period of two
(2) years following the Merger. See "PROPOSED MERGER -- Interests of Certain
Persons in the Merger."
    
 
APPRAISAL RIGHTS
 
     Under Delaware law, the AmeriFed stockholders will not be entitled to
appraisal or dissenters' rights with respect to the Merger. See "PROPOSED MERGER
- -- Appraisal Rights."
 
LIQUIDATION ACCOUNT
 
     In connection with its conversion from the mutual to the stock form of
ownership, AmeriFed Bank was required to establish a "liquidation account" for
the benefit of savings account holders at the time of the conversion. The
liquidation account grants such savings account holders who have continued to
maintain their savings accounts at AmeriFed Bank the right to a priority
distribution from the liquidation account before any distribution is made with
respect to AmeriFed Bank common stock in the event of a complete liquidation of
 
                                        7
<PAGE>   13
 
AmeriFed Bank. Neither the Merger nor the Subsidiary Bank Merger constitutes a
complete liquidation and will not trigger a distribution from the liquidation
account. Upon consummation of the Merger and the Subsidiary Bank Merger, the
liquidation account will be maintained by NBD Bank.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
   
     AmeriFed has obtained an opinion from Muldoon, Murphy & Faucette, counsel
to AmeriFed, substantially to the effect that the Merger will be treated as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code") and, accordingly, for federal income tax
purposes, no gain or loss will be recognized by AmeriFed or AmeriFed Bank as a
result of the Merger except, with respect to the Subsidiary Bank Merger, to the
extent AmeriFed or AmeriFed Bank is required to recognize taxable income due to
the recapture of AmeriFed Bank's bad debt reserves. AmeriFed has obtained an
opinion substantially to the effect that, for federal income tax purposes: (i)
assuming that the Merger transaction constitutes a merger under the applicable
state or federal law, the merger of AmeriFed with and into NBD Illinois will
constitute a reorganization within the meaning of Section 368(a)(1)(A) and
Section 368(a)(2)(D) of the Code, and AmeriFed, NBD Illinois and NBD will each
be a "party to a reorganization" within the meaning of Section 368(b) of the
Code; (ii) the basis of the assets of AmeriFed to be received by NBD Illinois
will be the same as the basis of those assets in the hands of AmeriFed
immediately prior to the Merger; (iii) the holding period of the assets of
AmeriFed to be received by NBD Illinois will include the holding period of those
assets in the hands of AmeriFed immediately prior to the Merger; (iv) no gain or
loss will be recognized by NBD Illinois and NBD upon receipt of the assets of
AmeriFed by NBD Illinois in exchange for the consideration provided for in the
Merger Agreement and the assumption by NBD Illinois of the liabilities of
AmeriFed; (v) NBD Illinois will succeed to and take into account the items of
AmeriFed described in Section 381(c) of the Code and NBD Illinois will be the
"acquiring corporation" within the meaning of Section 1.381(a)-1(b)(2) of the
regulations promulgated by the Department of Treasury ("Treasury Regulations")
and these items will be taken into account by NBD Illinois subject to the
conditions and limitations specified in Sections 381, 382 and 383 of the Code

AmeriFed on the Effective Date of Merger; and (x) the payments of cash in lieu
of fractional share interests of NBD Common Stock will be treated as having been

     AmeriFed stockholders are urged to consult their tax advisors concerning
the specific tax consequences to them of the Merger, including the applicability
and effect of various state, local and foreign tax laws. See "PROPOSED MERGER --
Certain Federal Income Tax Consequences of the Merger" and "-- Conditions to the
Merger."
 
STOCK EXCHANGE LISTING
 
     The NBD Common Stock is listed on the NYSE. NBD has agreed to cause the
shares of NBD Common Stock to be issued in the Merger to be approved for listing

RESALES OF NBD COMMON STOCK
 
     The NBD Common Stock will be freely transferrable by the holders of such
shares, except for those shares held by those holders who may be deemed to be
"affiliates" (generally including directors, certain executive officers and ten
percent or more shareholders) of AmeriFed or NBD under applicable federal
securities laws. See "PROPOSED MERGER -- Resales of NBD Common Stock."
 
ACCOUNTING TREATMENT
 
     The Merger is expected to qualify as a "purchase" for accounting and
financial reporting purposes. See "PROPOSED MERGER -- Accounting Treatment."
 
CONDUCT OF BUSINESS PRIOR TO THE MERGER
 
     The Reorganization Agreement contains certain covenants, to which AmeriFed
has agreed, regarding the business of AmeriFed prior to the Merger. The
covenants remain in effect until the Effective Date of Merger or until the
Agreements are terminated, and include, among other things, an agreement that
AmeriFed and each of its subsidiaries will conduct its affairs in the ordinary
course of business consistent with past and current practice, use its best
efforts to maintain and preserve its business organization, employees and
advantageous business relationships and to retain the services of its key
officers and employees. See "PROPOSED MERGER -- Business of AmeriFed Pending the
Merger."
 
COMPARISON OF STOCKHOLDER RIGHTS
 
     At the Effective Date of Merger, AmeriFed stockholders automatically will
become stockholders of NBD and their rights as stockholders of NBD will be
governed by Delaware General Corporation Law and by NBD's Certificate of
Incorporation and Bylaws. The rights of stockholders of NBD differ from those of
AmeriFed with respect to certain important matters, including, among others, the
absence of a 10% voting limit and supermajority approval provisions in the NBD
Certificate. See "COMPARATIVE RIGHTS OF HOLDERS OF CAPITAL STOCK OF AMERIFED AND
NBD."

     The following tables set forth certain historical consolidated financial
data for NBD for the five years ended December 31, 1993 and the six months ended

(a) The information presented for 1991 reflects the October 10, 1991 initial
     public offering of AmeriFed Common Stock and the concurrent combination of
     AmeriFed Bank into AmeriFed as if they had occurred on September 30, 1991.
     Information presented for years prior to 1991 is that of AmeriFed Bank, as
     AmeriFed had no operations prior to 1991.
    
 
   
(b) The information for years prior to the year ended September 30, 1992 is not
     meaningful since the initial public offering and concurrent combination
     were completed on October 10, 1991.
    
 
   
(c) Capital ratios presented are for AmeriFed Bank. The current regulatory
     capital adequacy requirements were not effective for fiscal years prior to
     1990.
    
 
MARKET VALUE OF SECURITIES
 
   
     The AmeriFed equivalent per share market value shown in the following table
is calculated on the basis that one share of AmeriFed Common Stock is equivalent
to approximately 1.44 shares of NBD Common Stock. The assumed exchange ratio is
based on the number of shares of fully diluted AmeriFed Common Stock outstanding
at June 30, 1994, the fixed transaction price of $45.00 per share of AmeriFed
Common Stock, and the average closing price of NBD Common Stock over a five day
trading period ending June 30, 1994 ($31.30). The actual Exchange Ratio will be
determined based on the average closing price per share of

RECENT FINANCIAL DEVELOPMENTS
 
   
     NBD. NBD earned net income of $390.1 million, or $2.44 per share, for the
nine months ended September 30, 1994, compared with net income of $366.8
million, or $2.27 per share, for the nine months ended September 30, 1993.
Operating earnings, or income before the effects of an extraordinary item and
accounting changes, were $405.8 million, or $2.54 per share, and $362.9 million,
or $2.24 per share, for the nine months ended September 30, 1994 and 1993,
respectively.
    
 
                                       12
<PAGE>   18
 
   
     Total assets were $45.6 billion and $40.4 billion at September 30, 1994 and
1993, respectively, and total deposits were $30.5 billion and $29.4 billion.
Total loans and leases were $27.9 billion at September 30, 1994, and the ratio
of nonperforming loans to total loans was 0.64%, compared with total loans and
leases of $25.3 billion and a ratio of nonperforming loans to total loans of
1.22% at September 30, 1993.
    
 
   
     Shareholders' equity totaled $3.3 billion at September 30, 1994, compared
with $3.2 billion at September 30, 1993. NBD's Tier 1 Capital Ratio was 8.63% at
September 30, 1994, the Total Capital Ratio was 12.18% and the Tier 1 Leverage
Ratio was 6.82%.
    
 
   
     The above financial information was derived from unaudited financial
statements and include, in the opinion of NBD management, all normal recurring
adjustments necessary for a fair presentation. The financial information is not
necessarily indicative of the results that may be expected for the full year or
any other interim period.
    
 
   
     AmeriFed. AmeriFed earned net income of $7.7 million, or $2.33 per share,
for the fiscal year ended September 30, 1994, compared to $10.0 million, or
$2.98 per share, for the fiscal year ended September 30, 1993. Net income for
the fourth quarter was $1.9 million, or $0.57 per share, compared to $2.5
million, or $0.75 per share, for the fourth quarter ended September 30, 1993.
    
 
   
     Net interest income decreased to $28.5 million for fiscal year 1994
compared to $32.4 million for fiscal 1993. Interest income decreased to $59.1
million compared to $66.2 million for the year ended September 30, 1993. The
decrease in interest income for fiscal year 1994 is largely due to a decline in
the average yield on interest earning assets to 6.85% for 1994 from 7.63% in
1993 as a result of loan refinancings and securities at lower yields and shorter
maturities. Net interest income for the fourth quarter was $7.4 million compared
to $7.7 million for the year ago quarter. Likewise, the average yield on
interest earning assets of 6.97% for the fourth quarter was lower compared to
7.31% for the year ago quarter. Interest expense also decreased to $30.6 million
for the year ended September 30, 1994 from $33.8 million for the year ended
September 30, 1993. The average cost of funds for fiscal 1994 decreased to 4.04%
from 4.41% in 1993. The average cost of funds for the fourth quarter in 1994 was
4.10% compared to 4.27% for the 1993 quarter. For the year ended September 30,
1994, non-interest income, excluding securities transactions, totaled $3.6
million compared to $3.1 million for 1993, an increase of 14.9%. The increase
was largely due to the $669,000, or 51%, increase in deposit service charge
income resulting from an increased checking base and revisions in deposit
services pricing methods and schedules, which was partially offset by a
reduction in brokerage and insurance commissions and decreased gains from the
sale of fixed rate mortgage loans in the secondary market.
    
 
   
     Non-interest expenses increased to $20.8 million for the year ended
September 30, 1994, compared to $18.1 million for the year ended September 30,
1993. Salary and benefits increased approximately $860,000 partially as a result
of increased compensation expense due to additional loan origination staff and
increased costs for employee health insurance and other benefits in 1994
compared to 1993. Federal deposit insurance premiums increased approximately
$337,000, primarily as a result of an increased deposit base. Merger related
costs of $560,000 were incurred. Marketing costs increased approximately
$431,000 due to increased promotion of checking and consumer loans products.
    
 
   
     Asset quality continued to exceed the national averages. Non-performing
loans to total gross loans decreased to .54% at September 30, 1994, compared to
.91% at September 30, 1993. The allowance for loan losses at September 30, 1994
was $4.5 million, or 150.95% of non-performing loans and .84% of net loans as
compared to $5.4 million or 120.85% and 1.14% respectively at September 30,
1993.
    
 
   
     The consolidated capital of AmeriFed at September 30, 1994 stood at $93.1
million (10.23% of total assets), or $28.90 per share. Consolidated tangible
capital represented 9.78% of total assets, or $27.64 per share.

                              MEETING INFORMATION
 
INTRODUCTION
 
     This Proxy Statement-Prospectus is being furnished to the stockholders of
AmeriFed in connection with the solicitation of proxies by the AmeriFed Board
for use at the Special Meeting. The Special Meeting will be held on December 9,
1994 at 3:00 p.m., local time, at the White Eagle Golf Club, 3400 Club Drive,
Naperville, Illinois 60564
 
PURPOSE
 
     The Special Meeting will be held for the purpose of considering and voting
upon a proposal to approve the Merger Agreement and to transact any and all
other business that may properly come before the Special Meeting.
 
VOTING RIGHTS AND RECORD DATE
 
   
     Only holders of record of AmeriFed Common Stock at the close of business on
the Record Date are entitled to notice of and to vote at the Special Meeting. On
the Record Date, 3,220,333 shares of AmeriFed Common Stock were issued and
outstanding. Approximately 459,356 shares (constituting approximately 14.3% of
the outstanding shares of AmeriFed Common Stock excluding currently exercisable
options) were beneficially owned by directors and executive officers of AmeriFed
and their affiliates on the Record Date. An unrelated corporate trustee of the
AmeriFed ESOP owned 224,702 shares of AmeriFed Common Stock on the Record Date
(constituting approximately 6.98% of the outstanding shares). Pursuant to the
terms of the ESOP, shares held by the ESOP that are allocated to the accounts of
the ESOP participants shall be voted by the ESOP trustee as directed by such
participants. Shares held by the ESOP that are currently unallocated shall be
voted by the ESOP trustee proportionate to the directions given by ESOP
participants with respect to allocated shares so long as such vote is in
accordance with the provisions of ERISA.
    
 
     Each holder of record of shares of AmeriFed Common Stock on the Record Date
will be entitled to one vote for each share registered in his or her name on
each matter presented to a vote of the stockholders at the Special Meeting,
except as described below. As provided in AmeriFed's Certificate of
Incorporation, recordholders of AmeriFed Common Stock who beneficially own in
excess of 10% of the outstanding shares of AmeriFed Common Stock (the "Limit")
are not entitled to any vote in respect to the shares held in excess of the
Limit. A person or entity is deemed to beneficially own shares owned by an
affiliate of, as well as persons acting in concert with, such person or entity.
 
   
     The presence, in person or by proxy, of a majority of the outstanding
shares of AmeriFed Common Stock entitled to vote (after subtracting any shares
in excess of the Limit) is necessary to constitute a quorum of the shareholders
in order to take action at the Special Meeting. For these purposes, shares of
AmeriFed Common Stock which are present or represented by proxy at the Special
Meeting will be counted for quorum purposes regardless of whether the holder of
the shares or proxy fails to vote on the Merger Agreement or whether a broker
with discretionary authority fails to exercise its discretionary voting
authority. Once a quorum is established, approval of the Merger Agreement
requires the affirmative vote of holders of a majority of the outstanding shares
of AmeriFed Common Stock. FOR VOTING PURPOSES THEREFOR, ABSTENTIONS AND "BROKER
NON-VOTES" WILL HAVE THE SAME EFFECT AS VOTES AGAINST THE MERGER AGREEMENT.
    
 
VOTING AND REVOCATION OF PROXIES
 
     Any stockholder giving a proxy prior to the Special Meeting has the right
to revoke it prior to its exercise by executing and delivering a later-dated
proxy, by delivering a written notice of revocation to the Secretary of
AmeriFed, or by attending the Special Meeting and voting in person. ALL PROXIES
WILL BE VOTED IN ACCORDANCE WITH THE DIRECTIONS OF THE STOCKHOLDER EXECUTING
SUCH PROXY AND, TO THE EXTENT NO DIRECTIONS ARE GIVEN, WILL BE VOTED "FOR"
APPROVAL OF THE MERGER AGREEMENT.

SOLICITATION OF PROXIES
 
     The enclosed proxy is being solicited by the AmeriFed Board for use in
connection with its Special Meeting. AmeriFed will bear its own expenses in
connection with the solicitation of proxies for its Special Meeting, except that
NBD shall pay the cost incurred in printing this Proxy Statement-Prospectus.
 
     In addition to solicitation of proxies by use of the mails, Kissel Blake, a
proxy solicitation firm, will assist AmeriFed in soliciting proxies for the
Special Meeting and will be paid a fee estimated to be $4,500, plus out-
of-pocket expenses. Directors, officers and regular employees of AmeriFed and
its subsidiaries may also make solicitations of proxies of stockholders either
personally or by telephone, telegram or other forms of communication. These
persons will not be specifically compensated for soliciting proxies. Brokerage
houses, custodians, nominees and fiduciaries will be requested to forward the
proxy soliciting materials to the beneficial owners of shares of AmeriFed Common
Stock held of record by such persons, and AmeriFed will reimburse them for their
charges and expenses.
 
                                PROPOSED MERGER
 
     This section of the Proxy Statement-Prospectus describes the material
features of the Agreements and the transactions contemplated thereunder. The
Merger Agreement sets forth the terms upon which the Merger, if consummated,
will be effected. The Reorganization Agreement sets forth various
representations, warranties and covenants of the parties relating to the
consummation of the Merger as well as the conditions which must be satisfied for
the Merger to be completed. The following description does not purport to be
complete and is qualified in its entirety by reference to the Agreements. All
stockholders are urged to read the Merger Agreement, which is set forth as
Appendix A to this Proxy Statement-Prospectus, in its entirety. A COPY OF THE
REORGANIZATION AGREEMENT WILL BE PROVIDED WITHOUT CHARGE TO ANY PERSON TO WHOM
THIS PROXY STATEMENT-PROSPECTUS IS DELIVERED UPON WRITTEN REQUEST TO ROBERT
BIEDRON, EXECUTIVE VICE PRESIDENT AND SECRETARY OF AMERIFED, OR DANIEL T. LIS,
SENIOR VICE PRESIDENT AND SECRETARY OF NBD, AT THEIR RESPECTIVE ADDRESSES
INDICATED UNDER "AVAILABLE INFORMATION".
 
GENERAL
 
   
     Under the terms of the Merger Agreement, AmeriFed will be merged with and
into NBD Illinois, a wholly-owned subsidiary holding company of NBD. Pursuant to
the Subsidiary Bank Merger, it is intended that immediately following the
Merger, AmeriFed Bank will merge with and into NBD Bank, a wholly-owned
subsidiary of NBD Illinois. If the proposed Merger is consummated, each share of
AmeriFed Common Stock will be converted into and be exchangeable for the number
of shares of NBD Common Stock equal to a fraction, the numerator of which shall
be equal to $45.00, and the denominator of which shall be equal to the average
closing price per share of NBD Common Stock as reported on the NYSE Composite
Tape for the five trading days ending on the fifth trading day prior to the
Effective Date of Merger.
    
 
BACKGROUND OF THE MERGER
 
     Originally chartered in 1934, AmeriFed Bank converted to a stock form of
organization and formed AmeriFed as its holding company in 1991. The period
subsequent to the conversion has been one of continued and substantial change in
the banking industry, characterized by heightened regulatory scrutiny, and
intensifying competition and consolidation. Management of AmeriFed and the
AmeriFed Board focused on these changes and sought to best position AmeriFed and
its stockholders.
 
     In light of an unsolicited expression of interest in AmeriFed from another
institution, the AmeriFed Board, in August of 1993, appointed a committee (the
"Committee") to evaluate the position AmeriFed should take in reference to
possible mergers, acquisitions and combinations, and in general any efforts
which might enhance stockholder value. After discussing with legal counsel the
considerations in selling AmeriFed and hearing presentations from several
financial advisory firms, the AmeriFed Board engaged The Chicago
 
                                       15
<PAGE>   21
 
Corporation in October of 1993 to render general financial advisory services as
well as merger and acquisition services to AmeriFed. The Chicago Corporation
prepared confidential information packets regarding AmeriFed, which were
distributed to potential buyers, and met with certain prospective buyers.
 
     From October of 1993 until March 1994, AmeriFed received several
preliminary indications of interest from other entities concerning the
possibility of pursuing a merger with or acquisition of AmeriFed. Other than
with respect to those matters discussed below, these indications of interest
were informal in nature and no formal offers resulted therefrom. All indications
of interest were analyzed by AmeriFed's financial advisor and were presented by
the senior management of AmeriFed to the Committee for review and analysis. Each
of these indications of interest was rejected by AmeriFed for a variety of
reasons, including the proposed range of consideration being discussed, the
timing of the offer, the pre-existing economic and market conditions, and the
proposed structure of the transaction.
 
     One such indication of interest came from NBD in February 1994. At that
time, AmeriFed's Chief Executive Officer, Robert B. Breidert, met with
representatives of NBD concerning NBD's interest in pursuing a possible
acquisition of AmeriFed. In the same time period, other such indications of
interest came from other bank holding companies about exploring the possibility
of acquiring AmeriFed. Members of senior management met with representatives of
NBD and the other institutions to discuss the terms of the proposed
acquisitions. On February 23, 1994, the Committee discussed NBD's indication of
interest as well as other indications of interest and allowed senior management
to go forward with further discussions. As a result of these discussions, NBD
and two other institutions performed preliminary due diligence, and NBD and one
of the other institutions submitted draft merger agreements regarding the
structure and terms of the proposed acquisitions.
 
     On March 23, 1994, the AmeriFed Board met to evaluate the proposals from
NBD and the other institution. At the meeting, a report was presented by The
Chicago Corporation regarding the two proposals and the proposed acquirors. The
Chicago Corporation representatives discussed the financial terms of the two
proposals, a description of the historical market prices of the institutions, a
comparison of the financial and market performance of AmeriFed to that of a
group of savings institutions in the Midwest, a comparison of each institution's
proposal to numerous recent transactions, an analysis of each institution's
financial ability to acquire AmeriFed relative to certain other banking
institutions and an analysis of the range of potential values of AmeriFed Common
Stock. Legal counsel, which was also present, discussed the AmeriFed Board's
fiduciary obligations in connection with the merger or acquisition of AmeriFed.
Members of senior management of AmeriFed, together with its legal and financial
advisors, reviewed with the AmeriFed Board, among other things, the background
and potential benefits of the transaction, including the strategic rationale for
the transaction. Of particular importance to the AmeriFed Board was the fact
that NBD's offer included a fixed price with a variable exchange ratio which was
not limited by any caps or collars (i.e. no maximum or minimum exchange ratio at
which the transaction would be restructured). At such time, The Chicago
Corporation rendered oral advice as to the fairness of the NBD consideration,
from a financial point of view, to be paid to holders of AmeriFed Common Stock.
Following further discussion, the AmeriFed Board unanimously approved the Merger
with NBD and authorized Mr. Breidert to execute the Agreements after review and
approval by legal counsel. Subsequently, the Agreements were executed and a
press release was issued that same day announcing the Merger.
 
REASONS FOR THE MERGER
 
   
     The AmeriFed Board, with the assistance of outside financial and legal
advisors, has evaluated the financial, legal and market conditions bearing on
the decision to recommend the Merger. The terms of the Merger, including the
price, are a result of arm's-length negotiations between representatives of
AmeriFed and NBD. In reaching its determination that the Merger Agreement is
fair to, and in the best interest of,
    
 
                                       16
<PAGE>   22
 
AmeriFed and holders of AmeriFed Common Stock, the AmeriFed Board considered a
number of factors, both from a short and long-term perspective, including,
without limitation, the following:
 
          (i) the AmeriFed Board's familiarity with and review of AmeriFed's
     business, financial condition, results of operations, management,
     prospects, including, but not limited to, its potential growth,
     development, productivity and profitability, and the business risks
     associated therewith;
 
          (ii) the current and prospective environment in which AmeriFed
     operates, including national and local economic conditions, the competitive
     environment for financial institutions generally, the increased regulatory
     burden on financial institutions generally and the trend toward
     consolidation in the financial services industry, particularly in
     AmeriFed's market area;
 
          (iii) information concerning the business, operations, asset quality
     and prospects of NBD, including recent acquisitions and the recent
     performance of NBD Common Stock;
 
          (iv) the oral and written presentation and oral opinion of AmeriFed's
     financial advisor, The Chicago Corporation, that the consideration was fair
     to the holders of AmeriFed Common Stock from a financial point of view;
 
          (v) the financial and other significant terms of the NBD offer
     compared to the other offer;
 
          (vi) the potential upside value offered in connection with the NBD
     offer compared to the other offer, and downside protection associated with
     the NBD offer compared to the other offer;
 
          (vii) the review by the AmeriFed Board with its legal and financial
     advisors of the provisions of the proposed Agreements;
 
          (viii) AmeriFed Board's belief that the terms of the proposed Merger
     with NBD were attractive in that they would allow AmeriFed stockholders to
     receive stock in the Merger, thus permitting stockholders to defer any tax
     liability associated with the increase in the value of their stock as a
     result of the Merger and to become stockholders in NBD, an institution with
     strong operations, management and earnings performance.
 
          (ix) the expectation that NBD will continue to provide quality service
     to the community and customers served by AmeriFed;
 
          (x) the compatibility of the respective business and management
     philosophies of AmeriFed and NBD;
 
          (xi) the broad range of products and services, as well as greater
     convenience, which will be afforded AmeriFed customers as a result of the
     Merger; and
 
          (xii) the alternative strategic courses available to AmeriFed,
     including remaining independent or exploring other indications of interest
     from other potential acquirors.
 
     THE IMPORTANCE OF THESE FACTORS RELATIVE TO ONE ANOTHER CANNOT PRECISELY BE
DETERMINED OR STATED HEREIN. THE AMERIFED BOARD UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT AMERIFED STOCKHOLDERS VOTE FOR
APPROVAL OF THE MERGER AGREEMENT.
 
EFFECTIVE DATE OF MERGER
 
     The Merger will be consummated at the close of business on the date
specified in a Certificate of Merger filed in accordance with the Delaware
General Corporation Law. The date on which the Merger will be consummated is
referred to herein as the "Effective Date of Merger." The Reorganization
Agreement provides that the Merger shall not be consummated prior to January 1,
1995. It is anticipated that if the stockholders of AmeriFed approve the Merger
Agreement at the Special Meeting and the approvals of all requisite government
regulatory authorities are obtained, the Effective Date of Merger will be early
in the first quarter of 1995, provided that the Agreements are not terminated
prior to such date. See "PROPOSED MERGER -- Conditions to the Merger" and "--
Termination, Amendment and Waiver."

OPINION OF FINANCIAL ADVISOR TO AMERIFED
 
     The Chicago Corporation has delivered its written opinion to the AmeriFed
Board that, based upon and subject to the various considerations set forth in
the opinion dated October 24, 1994, the consideration being received by AmeriFed
stockholders in the Merger is fair from a financial point of view to AmeriFed's
stockholders as of the date of its opinion. At each stage of The Chicago
Corporation's engagement, the AmeriFed Board carefully and thoroughly reviewed
the materials and presentations of The Chicago Corporation and made inquiries of
The Chicago Corporation personnel as to the methodology and the assumptions
utilized in its analysis. No limitations were imposed by the AmeriFed Board upon
The Chicago Corporation with respect to the investigations made or procedures
followed by it in rendering its opinion.
 
     The full text of the opinion of The Chicago Corporation, which sets forth
assumptions made, matters considered and limitations on the review undertaken,
is attached hereto as Appendix B. AmeriFed stockholders are urged to read the
opinion.
 
     The Chicago Corporation's opinion is directed only to the consideration to
be received in the Merger and does not constitute a recommendation to any
AmeriFed stockholders as to how such stockholder should vote at the Special
Meeting. The summary of the opinion of The Chicago Corporation set forth in this
Proxy Statement-Prospectus is qualified in its entirety by reference to the full
text of such opinion attached hereto as Appendix B.
 
     AmeriFed retained The Chicago Corporation as its financial advisor on the
basis of the firm's reputation, experience and familiarity with the banking
industry and with merger and acquisition transactions. As part of its investment
banking business, The Chicago Corporation is regularly engaged in the valuation
of businesses in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuation for corporate and other purposes.
 
     During the course of its engagement, and as a basis for arriving at its
opinion, The Chicago Corporation reviewed and analyzed material bearing upon the
financial and operating condition of AmeriFed and NBD and material prepared in
connection with the Merger, as follows: (i) the Merger Agreement; (ii) publicly
available information concerning AmeriFed and NBD, consisting of required
regulatory financial statements and Consolidated Reports of Condition and Income
for each of the last five fiscal years; (iii) the nature and terms of recent
sale and merger transactions involving thrift and bank holding companies that
The Chicago Corporation considered reasonably similar to AmeriFed and NBD in
size, financial character, operating character, historical performance and
geographic market; (iv) historical and current market data for AmeriFed Common
Stock and NBD Common Stock and financial and other information provided to The
Chicago Corporation by the managements of AmeriFed and NBD, consisting of loan
review and asset quality information, asset-liability management information,
subsidiary bank performance and management reports, and budget and planning
information; and (v) the Registration Statement and this Proxy Statement-
Prospectus. These analyses are discussed in more detail below. In addition, The
Chicago Corporation conducted meetings with members of senior management of
AmeriFed and NBD for the purpose of reviewing the future prospects of AmeriFed
and NBD. The Chicago Corporation evaluated the pro forma ownership of NBD Common
Stock by AmeriFed stockholders, relative to the pro forma contribution of
AmeriFed's assets, liabilities, equity and earnings of the proposed combined
company. The Chicago Corporation also took into account its experience in other
transactions, as well as its knowledge of the banking industry and its general
experience in securities valuations. In rendering its opinion, The Chicago
Corporation assumed without independent verification, the accuracy and
completeness of the financial and other information and representations provided
to it by AmeriFed and NBD.
 
     The following is a summary of the material terms considered and the
analyses performed by The Chicago Corporation in rendering its opinion during
the course of its engagement in connection with its October 24, 1994 opinion.
 
     Net Present Value Analysis. The Chicago Corporation prepared a net present
value analysis which indicated theoretical values for AmeriFed based on return
on average assets ranging between 1.00% and 1.25% and asset growth rates ranging
between 2.00% and 10.00%. The results of this analysis indicated a range of
 
                                       18
<PAGE>   24
 
   
theoretical values for AmeriFed between $25.13 per share (1.00% return on
average assets; 2.00% asset growth rate) and $40.17 per share (1.25% return on
average assets; 10.00% asset growth rate). With a return on average assets of
1.00%, which approximated AmeriFed's recent historical performance, theoretical
values ranged from $25.13, (2.00% asset growth rate) to $32.21 (10.00% asset
growth rate). At an asset growth rate of 2.00%, which approximated AmeriFed's
recent historical performance, theoretical values ranged from $25.13 (1.00%
return on average assets) to $31.31 (1.25% return on average assets). The
nominal value of the offer from NBD based on the five-day closing average for
NBD Common Stock on October 24, 1994 of $29.65 was $45.00.
    
 
   
     Contribution Analysis. The Chicago Corporation prepared a contribution
analysis showing the percentages of assets, deposits, common equity, 1993 and
estimated 1994 and 1995 net income contributed to the combined company on a pro
forma basis by AmeriFed and NBD, and compared these percentages to the pro forma
ownership of NBD. This analysis showed that AmeriFed, as of September 30, 1994,
would contribute 1.96% of pro forma consolidated total assets, 2.54% of
deposits, 2.78% of common equity, 2.03% of 1993 net income, 1.51% of estimated
1994 net income and 1.63% of estimated 1995 net income. Based on the NBD offer,
stockholders of AmeriFed would own approximately 3.18% of the pro forma
outstanding NBD Common Stock.
    
 
   
     Comparable Transaction Analysis. The Chicago Corporation reviewed selected
comparable merger and acquisition transactions. The following merger
transactions were reviewed based on publicly available data (the acquiror is
named first and italicized, followed by the seller): Firstar Corp., Investors
Bank Corp.; First Bancorporation of Ohio, Civista Corp.; Fifth Third Bancorp,
Cumberland Federal; Standard Federal Bank, Heritage Bancorp; Huntington
Bancshares, Railroadmen's FSLA; TCF Financial Corp., Great Lakes Bancorp;
Mid-Am, Inc., Security First Corp.; Mercantile Bancorp, UNSL Financial Corp.;
First of America Bank Corporation, LGF Bancorp, Inc.; First Bancorporation of
Ohio, Great Northern Financial; Roosevelt Bancorp, Home Federal Bancorp of MO;
Mercantile Bancorp, United Postal Bancorp; Fourth Financial Corp., Great
Southern Bancorp; and Fifth Third Bancorp, TriState Bancorp.
    
 
   
     Transactions were selected on the basis of comparability of transaction
value and the perceived comparability of the markets served by the acquired
institutions to those of AmeriFed. For the comparable transactions, the multiple
of price to trailing 12 months earnings ranged from 7.41 to 20.05 with an
average of 14.30. At September 30, 1994, the NBD proposed purchase price
represented a multiple of trailing 12 months earnings of 18.00.
    
 
   
     For the comparable transactions, the percentage of purchase price to book
value ranged from 152.06% to 218.60% with an average of 177.71%. The NBD offer
to AmeriFed represented a percentage to September 30, 1994 book value of
157.67%.
    
 
   
     Financial Implications to AmeriFed Stockholders. The Chicago Corporation
prepared an analysis of the financial implications of the NBD offer to an
AmeriFed stockholder. This analysis indicated that on a pro forma equivalent
basis a stockholder of AmeriFed would achieve an increase in earnings per share,
an increase in per share dividends and an increase in book value per share as a
result of the consummation of the Merger.
    
 
   
     Comparative Stockholder Returns. The Chicago Corporation presented an
analysis of comparative theoretical stockholder returns for several scenarios,
including AmeriFed remaining independent, AmeriFed being acquired in 1997 and
AmeriFed being acquired in 1994 by NBD. This analysis, which was based on
projected dividend streams and projected 1997 common stock valuations (using
current price-to-earnings multiples), indicated total stockholder returns of
8.35% for AmeriFed remaining independent, 15.79% for a merger in 1997 and 25.24%
based on the acceptance of NBD's offer in 1994. The Chicago Corporation also
prepared an analysis of the possible pricing of a merger transaction with
certain other thrift and bank holding companies using estimated 1995 net income
for AmeriFed and stock prices of selected companies assuming no earnings per
share dilution for the buyer, a 30% reduction in non-interest expenses due to
operating efficiencies and a 100% stock transaction without share repurchases by
the acquiror. The holding companies reviewed included: BankAmerica Corp.;
NationsBank Corp.; Banc One Corporation; First Union Corp.; First Chicago Corp.;
Norwest Corporation; NBD Bancorp, Inc.; National City Corp.; Comerica Inc.;
First Bank System, Inc.; First of America Bank Corp.; Huntington Bancshares;
Firstar Corporation; Fifth Third Bancorp;
    
 
                                       19
<PAGE>   25
 
   
Michigan National Corp.; Old Kent Financial; Marshall & Ilsley Corp.; First
Midwest Bancorp; AMCORE Financial, Inc.; Firstbank of Illinois Co.; and River
Forest Bancorp.
    
 
   
     Given the assumptions, the analysis indicated that these companies could
pay a high of $52.28 per share and a low of $27.76 per share for all of the
shares of AmeriFed.
    
 
   
     Comparable Company Analysis. The Chicago Corporation compared the market
price, market-to-book value and price-to-earnings multiples of NBD Common Stock
with the individual market multiples and averages of the following selected
comparable companies which it deemed to be reasonably similar to NBD in size,
financial character, operating character, historical performance and/or
geographic market: Banc One Corporation; Norwest Corporation; Comerica
Incorporated; National City Corporation; First Bank System, Inc.; First of
America Bank Corp.; Huntington Bancshares Inc.; Fifth Third Bancorp; Firstar
Corporation; and Old Kent Financial.
    
 
     This analysis indicated that NBD Common Stock sold at a price of 1.44 times
the September 30, 1994 book value and the comparables sold at an average price
of 1.72 times book value. NBD Common Stock sold at a multiple of price to
trailing 12 months earnings of 9.5, while the comparable group average price-to-
earnings multiple was 10.3.
 
     The summary of The Chicago Corporation analysis set forth above is a fair
summary thereof but does not propose to be a complete description of the
presentations by The Chicago Corporation to the AmeriFed Board. The Chicago
Corporation believes that its analysis and the summary set forth above must be
considered as a whole and that selecting portions of analysis, without
considering all factors and analyses, could create an incomplete view of the
process by which a fairness opinion is rendered. In connection with its
analyses, The Chicago Corporation assumed that there would be no material
adverse change in general economic, business, market and/or regulatory
conditions, all of which are beyond the control of NBD and AmeriFed. The
analyses performed by The Chicago Corporation are not necessarily indicative of
actual values of future results, which may be significantly more or less
favorable than suggested by such analyses.
 
     Fees and Indemnification. The fees due to The Chicago Corporation under the
agreement between The Chicago Corporation and AmeriFed ("The Chicago Corporation
Agreement") are payable by AmeriFed as follows: $25,000 at the date of execution
of The Chicago Corporation Agreement, a cash fee equal to 0.30% of the total
consideration of the transaction payable at the time a definitive agreement is
signed and a cash fee equal to 0.80% of the total consideration of the
transaction (less the $25,000 and the fee payable on the signing of a definitive
agreement) payable at the closing.
 
     In addition to such fees, AmeriFed has agreed to reimburse The Chicago
Corporation for all reasonable out-of-pocket expenses and will pay to The
Chicago Corporation a fee of $1,500 per day for preparation and court
appearances should The Chicago Corporation be called upon in any legal
proceeding to deliver expert testimony with regard to the fairness opinion.
AmeriFed has also agreed to indemnify The Chicago Corporation, its officers,
directors, agents, employees and certain controlling persons from and against
any losses, claims, damages and liabilities in connection with or arising out of
the transactions or services referred to in The Chicago Corporation Agreement.
This indemnification is subject to certain conditions and procedures set forth
in an indemnification agreement between AmeriFed and The Chicago Corporation.
 
CONSIDERATION FOR SHARES
 
     The rate of exchange and general terms of the Agreements were arrived at
through arms-length negotiations between NBD and AmeriFed.
 
     NBD Common Stock in the Merger. Upon consummation of the Merger, each
outstanding share of AmeriFed Common Stock (other than shares owned by NBD, NBD
Illinois or AmeriFed, which will be cancelled) will be automatically converted
and exchanged for a number of shares of NBD Common Stock equal to a fraction,
the numerator of which shall be equal to $45.00, and the denominator of which
shall be equal to the average closing price per share of NBD Common Stock as
reported on the NYSE Composite Tape for the five trading days ending on the
fifth trading day prior to the Effective Date of Merger, as defined in the
Merger Agreement.
 
                                       20
<PAGE>   26
 
     Cash in Lieu of Fractional Shares. Each holder of a certificate or
certificates representing shares of AmeriFed Common Stock who would otherwise
have been entitled to receive a fraction of a share of NBD Common Stock (after
taking into account all AmeriFed Common Stock represented by such certificate or
certificates then delivered by such holder) shall receive, in lieu thereof, an
amount of cash (without interest) determined by multiplying such fraction by the
average closing price of a whole share of NBD Common Stock on the NYSE Composite
Tape during the five trading days ending on the fifth trading day prior to the
Effective Date of Merger.
 
DELIVERY OF NBD COMMON STOCK
 
     As promptly as practicable after the Effective Time of the Merger, NBD will
cause appropriate transmittal materials to be mailed to each AmeriFed
stockholder of record on the Effective Date of Merger for the purpose of
exchanging his or her share certificates. NBD or State Street Bank and Trust
Company, as exchange agent (the "Exchange Agent"), will mail or deliver to each
former AmeriFed stockholder whose shares have been converted into NBD Common
Stock and who has surrendered his or her certificates representing AmeriFed
Common Stock, a certificate or certificates representing the number of whole
shares of NBD Common Stock to which the stockholder is entitled plus a check in
the amount of cash paid in lieu of fractional shares. The Merger Agreement
provides that after the Effective Date of Merger and until AmeriFed Common Stock
certificates are exchanged, no dividend payable with respect to NBD Common Stock
will be paid to the holders of certificates previously representing AmeriFed
Common Stock. Upon exchange of such certificates, however, there will be paid
the amount (without interest and less the amount of taxes, if any, which may
have been imposed or paid thereon) of all dividends, if any, which shall have
been declared and paid after the Effective Date of Merger with respect to the
shares of NBD Common Stock issuable under the Merger Agreement in respect of the
AmeriFed Common Stock represented by such surrendered certificates. To avoid
backup Federal income tax withholding on payments made to them, stockholders of
AmeriFed will be required to furnish their taxpayer identification numbers and
appropriate certifications to the Exchange Agent on the transmittal form.
 
     After the Effective Date of Merger, there will be no further transfer on
the books of AmeriFed of certificates theretofore representing AmeriFed Common
Stock and, if such certificates are presented for transfer, they will be
cancelled against delivery of certificates for NBD Common Stock as described
herein.
 
     CERTIFICATES FOR AMERIFED COMMON STOCK SHOULD NOT BE SENT TO THE EXCHANGE
AGENT AT THIS TIME, BUT ONLY WHEN A STOCKHOLDER HAS RECEIVED A TRANSMITTAL FORM.
 
     Shares of NBD Common Stock issued and outstanding immediately prior to the
Effective Date of Merger will remain issued and outstanding and will be
unaffected by the Merger, and holders of such NBD Common Stock will not be
required to exchange the certificates evidencing such stock or take any other
action by reason of the consummation of the Merger.
 
SOURCE OF NBD COMMON STOCK
 
     The shares of NBD Common Stock that will be utilized in the Merger may be
authorized and unissued shares and/or treasury shares. At the time of the
announcement of execution of the Agreements, NBD also announced its intention to
repurchase the number of shares of NBD Common Stock to be exchanged in the
Merger, and that repurchase program is substantially complete. All such
repurchases have and shall comply with the requirements of the Commission, the
NYSE and applicable regulatory authorities. In addition, the Merger Agreement
prohibits such repurchases during the 30-day period prior to the Effective Date
of Merger.
 
CONDITIONS TO THE MERGER
 
     The Reorganization Agreement sets forth various representations, warranties
and covenants of the parties relating to the consummation of the Merger,
conditions which must be satisfied before the Merger may be consummated and
grounds for termination of the Merger, as discussed below. The representations
and warranties include, among other things, the parties' organization, financial
condition, capitalization, pending
 
                                       21
<PAGE>   27
 
   
and threatened litigation and enforceability of the Merger Agreement. The
obligations of NBD, NBD Illinois and AmeriFed to cause the Merger to be
consummated are subject to the following conditions, among others: (i) approval
of the Merger Agreement by the stockholders of AmeriFed; (ii) approval of the
Merger by all requisite government regulatory authorities without any conditions
which in the reasonable opinions of NBD and AmeriFed are materially adverse, and
such approvals have not been withdrawn or stayed, and all statutory waiting
periods have expired; (iii) delivery of officers' certificates by each party
certifying as to representations and warranties made by each party; (iv)
delivery of certain legal opinions, including a favorable tax opinion; (v) the
Registration Statement, of which this Proxy Statement-Prospectus is a part, is
declared effective under the Securities Act of 1933, as amended and no stop
order has been issued or threatened; (vi) neither NBD nor AmeriFed is subject to
any order or decree of a court or agency of competent jurisdiction enjoining or
prohibiting the Merger; (vii) the shares of NBD Stock to be delivered to
AmeriFed shareholders pursuant to the Merger are approved for listing on the
NYSE; and (viii) an opinion has been received by AmeriFed from The Chicago
Corporation to the effect that consideration received by AmeriFed stockholders
in the Merger is fair from a financial point of view.
    
 
REGULATORY MATTERS
 
     Bank holding companies (such as NBD and NBD Illinois), savings and loan
holding companies (such as AmeriFed), and their respective depository
institution subsidiaries (including NBD Bank and AmeriFed Bank, respectively)
are highly regulated institutions, with numerous federal and state laws and
regulations governing their activities. Among these are laws and regulations
requiring prior approval by applicable government regulatory authorities in
connection with acquisition and merger transactions such as the Merger and the
Subsidiary Bank Merger, as summarized below. In addition, these institutions are
subject to ongoing supervision, regulation, and periodic examination by various
federal and state financial institution regulatory agencies. Detailed
discussions of such ongoing regulatory oversight and the laws and regulations
under which it is carried out can be found in the Forms 10-K of each of NBD and
AmeriFed incorporated by reference herein. See "AVAILABLE INFORMATION" and
"INFORMATION INCORPORATED BY REFERENCE." Those summaries are qualified in their
entirety by the actual language of the laws and regulations, which are subject
to change based on recently enacted and future legislation and action by
regulatory agencies. As an example, recently enacted legislation would, among
other things, permit nationwide interstate bank acquisitions in one year and
nationwide interstate branching in three years, subject in the case of branching
to the right of states to "opt out" of the legislation.
 
   
     Applications for approval of the Merger and/or the Subsidiary Bank Merger
have been submitted to the Federal Deposit Insurance Corporation ("FDIC"), the
Federal Reserve Bank of Chicago (the "FRB"), the Office of Thrift Supervision
("OTS"), and the Illinois Commissioner of Banks and Trust Companies (the
"Illinois Commissioner"). The FDIC applications, which were approved on October
18, 1994, were submitted pursuant to Sections 5(d)(3)("Oakar II") and 18(c)(the
"Bank Merger Act") of the Federal Deposit Insurance Act. The Bank Merger Act
requires that the applicable regulator take into consideration, among other
factors, the financial and managerial resources and future prospects of the
merging institutions as well as the convenience and needs of the communities to
be served by the resulting institution (including compliance with
anti-competitive concerns, Community Reinvestment Act provisions, and fair
lending laws). Under the Bank Merger Act, the proposed transaction may not be
consummated prior to the 30th day following the date of approval of the
applicable federal regulatory agency (in this case the October 18 approval of
the FDIC), during which time the United States Department of Justice (the "DOJ")
may challenge the transaction on antitrust grounds. The post-approval waiting
period may be reduced by the FDIC, with the concurrence of the DOJ, to a minimum
of 15 days. The FRB application, which was approved on October 25, was submitted
pursuant to Section 4 of the Bank Holding Company Act, under which the FRB takes
into consideration substantially the same factors considered under the Bank
Merger Act. The OTS applications were filed pursuant to the provisions of the
Home Owners Loan Act and related OTS regulations, pursuant to which the OTS will
take into consideration a number of factors similar to those indicated above as
well as the structure of the proposed transaction, whether the acquiring bank
has agreed to assume the thrift's liquidation account obligations, and whether
the terms of the transaction and the benefits to be received by management of
the thrift have been fully disclosed to the thrift's stockholders. The
application filed with the Illinois Commis-
    
 
                                       22
<PAGE>   28
 
sioner seeks approval for the Subsidiary Bank Merger pursuant to the Illinois
Banking Act, and focuses on substantially the same considerations as the Bank
Merger Act.
 
   
     The Merger and therefore the Subsidiary Bank Merger cannot proceed in the
absence of all requisite regulatory approvals. There can be no assurance each of
the OTS and the Illinois Commissioner will approve the Merger and/or the
Subsidiary Bank Merger, and if they are approved, there can be no assurance as
to the date of such approvals.
    
 
TERMINATION, AMENDMENT AND WAIVER
 
     It is contemplated that the conditions to the Merger noted above will be
fulfilled prior to the consummation of the Merger. If, however, any one or more
of such conditions, other than the approval of the Merger Agreement by the
stockholders of AmeriFed and the approval of the transaction by all required
governmental authorities, shall not have been satisfied, the party whose
obligation to proceed is made subject to the satisfaction of such condition may,
nevertheless, at its election waive such condition and proceed with the Merger.
 
     The Agreements may be terminated and the Merger abandoned at any time prior
to the Effective Date of the Merger, either before or after approval of the
Merger Agreement by the stockholders of AmeriFed, in any of the following ways
among others: (i) by mutual consent of NBD and AmeriFed; (ii) by either NBD or
AmeriFed if the terminating party provides written notice of a material breach
of any representation, warranty or agreement contained in the Reorganization
Agreement within a specified period after its discovery and such breach is not
cured within sixty days after such written notice; (iii) by either NBD or
AmeriFed if the Effective Date of Merger has not occurred on or before March 31,
1995; (iv) by either NBD or AmeriFed if a final unappealable injunction or other
judgment shall have been issued by a court restraining or prohibiting
consummation of the transactions contemplated by the Reorganization Agreement;
and (v) by either NBD or AmeriFed if a required government regulatory approval
shall have been refused or shall have been conditioned in a manner not
reasonably satisfactory to NBD, provided that NBD shall have the right to
initiate and pursue expeditiously an appeal from any such refusal or imposition
of an unsatisfactory condition and, in the event of such appeal, such refusal or
imposition of condition shall be deemed not to have been made until the
termination of such appeal or the time that such refusal or imposition of a
condition has become final and non-appealable. Any such termination shall be
approved by the appropriate Board of Directors.
 
     In the event the Agreements are terminated and the Merger abandoned by
virtue of the grounds set forth in clause (ii) above, the party causing such
breach shall reimburse the other party for all reasonable expenses incurred by
such party in connection with the transactions contemplated by the Merger
Agreement. In the event of such a termination due to any other cause, each party
shall bear its own expenses. In the event the Agreements are terminated and the
Merger abandoned despite the best efforts of the parties, no party shall incur
any liability except to the extent described above with respect to expenses.
 
     The Agreements may be amended, or any of the terms or conditions thereof
waived, at any time before or after approval of the Merger Agreement by the
stockholders of AmeriFed; provided, however, that any such change which is
proposed subsequent to stockholder approval may not, without further approval of
such stockholders, alter or change the amount or kind of consideration to be
received in the Merger or alter or change any of the terms and conditions of the
Merger Agreement if such alternation or change would adversely affect such
stockholders.
 
BUSINESS OF AMERIFED PENDING THE MERGER
 
     The Reorganization Agreement also contains covenants to which AmeriFed has
agreed. The covenants remain in effect until the Effective Date of Merger or
until the Agreements are terminated, and include, among others, an agreement
that AmeriFed and each of its subsidiaries will conduct its affairs in the
ordinary course of business consistent with past and current practice, use its
best efforts to maintain and preserve its business organization, employees and
advantageous business relationships and to retain the services of its key
officers or employees. Neither AmeriFed nor its subsidiaries shall, without
prior written consent of NBD: (i) enter into any employment, severance or other
personnel contract or plan with any director, officer or
 
                                       23
<PAGE>   29
 
employee, except for approval of renewal of existing agreements and payment of
bonuses in the normal course of business and consistent with past practice; (ii)
except for shares issued pursuant to employee and director stock options, issue
any capital stock or any security convertible into capital stock, or grant any
option, warrant or other rights to acquire capital stock, effect any stock
split, adjustment or recapitalization, or otherwise alter its capital structure;
(iii) propose or adopt any amendment to its articles of incorporation,
association or other charter document; (iv) purchase, redeem, retire or
otherwise acquire or dispose of any shares of its capital stock; (v) take any
action which would cause any significant decrease in the book value of the
shares of its capital stock or which would have a material adverse affect on its
financial condition, subject to the right of AmeriFed and its subsidiaries to
value assets in accordance with applicable legal and accounting requirements;
(vi) enter into any contract or arrangement other than in the ordinary course of
business; (vii) make or commit to make any capital expenditure in an amount
exceeding $100,000; or (viii) take any action that would adversely effect or
delay the ability of NBD or AmeriFed to obtain requisite regulatory approvals or
to perform any of the covenants and agreements under the Reorganization
Agreement, or which would make any of the representations and warranties made in
the Reorganization Agreement untrue or incorrect in any material respect.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     At November 1, 1994, all directors and executive officers of AmeriFed as a
group beneficially owned 581,715 shares or 17.4 percent of the outstanding
shares of AmeriFed Common Stock, including options which are currently
exercisable. No director or executive officer of AmeriFed owns any NBD Bancorp
Common Stock.
 
     Certain members of AmeriFed's management and the AmeriFed Board may be
deemed to have certain interests in the Merger that are in addition to their
interests as stockholders of AmeriFed generally, including the interests
described below. The AmeriFed Board was aware of these interests, and considered
them, among other matters, in approving the Merger Agreement and the
transactions contemplated thereby.
 
     Employment Agreements and Special Termination Agreements. AmeriFed and
AmeriFed Bank maintain employment agreements with Mr. Breidert. In addition,
AmeriFed Bank and AmeriFed also maintain special termination agreements with
each of the following executive officers: Robert Biedron, Stephen G.
Morrissette, Robert F. Maxwell, and John M. Luxem.
 
   
     The employment agreements between AmeriFed and AmeriFed Bank and Mr.
Breidert provide for concurrent two-year terms. Commencing on the first
anniversary date and continuing each anniversary date thereafter, the agreements
extend for an additional year so that the remaining terms shall be two years
unless written notice is given by the AmeriFed Board after conducting a
performance review of the executive. The agreements provide that the base salary
of the executive will be reviewed by the Board annually.
    
 
     In addition to the base salary, the agreements provide for, among other
things, disability pay, participation in stock benefit plans and other fringe
benefits applicable to executive personnel. The agreements provide for
termination by AmeriFed and AmeriFed Bank for cause at any time. In the event
AmeriFed and AmeriFed Bank elects to terminate the executive's employment for
reasons other than for cause, or in the event of the executive's resignation
from AmeriFed and AmeriFed Bank upon a (i) failure to re-elect the executive to
his current offices or nominate the executive for Board membership, (ii)
material change in the executive's functions, duties, or responsibilities, or
relocation of his principal place of employment, (iii) liquidation or
dissolution of AmeriFed and AmeriFed Bank, or (iv) material breach of the
agreement by AmeriFed and AmeriFed Bank, the executive will be entitled to
receive a severance payment equal to the greater of the remaining salary
payments due under the agreements or one year's compensation based upon the
highest salary level during the term of the agreements.
 
     If termination, voluntary (as defined in the agreements) or involuntary,
results from a change in control of AmeriFed and AmeriFed Bank, the executive
or, in the event of death, his beneficiary, would be entitled to receive a
severance payment equal to three times his average compensation (base salary,
including bonus and other cash or other benefits paid) over the past three years
of employment with AmeriFed and AmeriFed
 
                                       24
<PAGE>   30
 
Bank. AmeriFed and AmeriFed Bank would also continue the executive's life,
health, accident, dental and disability coverage, and such coverage and payments
shall cease upon the expiration of 36 months. The consummation of the
transactions contemplated by the Merger Agreement will constitute a change in
control for purposes of the employment agreements.
 
   
     If a material change in Mr. Breidert's functions, duties or
responsibilities occurs, which change in his position would be the case
subsequent to the Merger, and Mr. Breidert terminates employment following the
change in control, Mr. Breidert will receive approximately $1,378,725 in
severance payments in addition to other non-cash benefits provided under the
Merger Agreement. The Reorganization Agreement provides that NBD will honor Mr.
Breidert's agreement.
    
 
   
     Each special termination agreement provides for a three-year term.
Commencing on the first anniversary date and continuing on each anniversary
thereafter, the agreements will be extended so that the remaining term shall be
three years. Each agreement provides that at any time following a change in
control of AmeriFed and AmeriFed Bank, if AmeriFed and AmeriFed Bank (or their
successors) terminates the executive's employment for any reason other than
cause, or if the executive terminates his employment following his demotion,
loss of title, office or significant authority, a reduction in his compensation,
or relocation of his principal place of employment, the executive or, in the
event of death, his beneficiary, would be entitled to receive a severance
payment equal to three times his average compensation (base salary, including
bonus and any other cash or other benefits paid) over the past three years of
his employment with AmeriFed Bank. AmeriFed and AmeriFed Bank would also
continue the executive's life, health, accident, dental and disability coverage,
and such coverage and payments shall cease upon the expiration of 36 months.
Payments to the executive under the AmeriFed Bank agreements are guaranteed by
AmeriFed in the event that payments or benefits are not paid by the AmeriFed
Bank. The consummation of the transactions contemplated by the Merger Agreement
will constitute a change in control for purposes of these agreements.
    
 
   
     If an executive officer leaves after the change in control and one of the
other factors described above occurs, based upon current compensation, Messrs.
Biedron, Morrissette, Maxwell or Luxem would receive severance payments of
approximately $932,500, $779,574, $730,951, and $576,723, respectively. The
Reorganization Agreement provides that NBD will honor these agreements.
    
 
   
     Payments under the employment agreements and special termination agreements
in the event of a change in control may constitute an excess parachute payment
under Section 280G of the Internal Revenue Code of 1986, as amended, (the
"Code"), resulting in the imposition of an excise tax on the recipient and
denial of a deduction to AmeriFed generally for all amounts in excess of three
times the executive's average annual compensation for the five tax years
preceding the change in control. The agreements provide that benefits payable to
the executive under a change in control may be reduced to an amount that would
not constitute an excess parachute payment (as that term is defined in Section
280G of the Code) if the reduced amount is greater than the non-reduced amount
less payment of any excise tax.
    
 
   
     Option Plans and Recognition and Retention Plans. AmeriFed maintains an
incentive stock option plan and certain recognition and retention plans which
provide for an immediate acceleration of the vesting period for benefits payable
under the plans upon a change in control. The Merger will constitute a change in
control under such plans. AmeriFed also maintains a directors' option plan.
    
 
     Additionally, pursuant to the terms of the Reorganization Agreement with
respect to officers and employees of AmeriFed or AmeriFed Bank who will remain
employed by NBD or any of its subsidiaries, each option granted by AmeriFed to
purchase shares of AmeriFed Common Stock which is outstanding and unexercised
immediately prior to the Effective Date of Merger shall be converted
automatically into an option to purchase, at an exercise price of $10.00 per
share, a number of shares of NBD Common Stock equal to a fraction, the numerator
of which shall be equal to $45.00 and the denominator of which shall be equal to
the average closing price per share of NBD Common Stock as reported on the NYSE
Composite Tape for five trading days ending on the fifth trading day prior to
the Effective Date of the Merger. With respect to directors of AmeriFed or
AmeriFed Bank as well as officers and employees of AmeriFed or AmeriFed Bank
holding options of AmeriFed whose service will terminate upon the Merger, each
option to purchase shares of
 
                                       25
<PAGE>   31
 
AmeriFed Common Stock which is outstanding and unexercised immediately prior to
the Effective Date of Merger shall be converted automatically into a number of
shares of NBD Common Stock equal to a fraction, the numerator of which shall be
equal to $35.00 and the denominator of which shall be equal to the average
closing price per share of NBD Common Stock as reported on the NYSE Composite
Tape for five trading days ending on the fifth trading day prior to the
Effective Date of the Merger.
 
     Post-Merger Compensation Benefits. The Reorganization Agreement provides
that, after the Effective Date of Merger, employees and officers of AmeriFed who
become employees of NBD or its subsidiaries shall be entitled to participate in
NBD's pension, benefit and similar plans on the same terms and conditions as
employees and officers of NBD, giving effect to years of service with AmeriFed
as if such service were with NBD.
 
   
     The Reorganization Agreement provides that each employee who, except for
those executive officers who have employment agreements or special termination
agreements, is terminated will receive salary continuation payments under the
terms of the AmeriFed Severance Compensation Plan (the "Severance Plan"). Under
the Severance Plan, in the event a change in control of AmeriFed or AmeriFed
Bank occurs, participants in the Severance Plan who are terminated or terminate
(as determined under the Severance Plan) will be entitled to receive a severance
payment. If the participant whose employment has terminated has completed at
least five years of service, the participant will be entitled to a cash
severance payment equal to one-twelfth of the compensation paid during the 12
months preceding the participant's termination for each year of employment with
AmeriFed Bank, up to a maximum of 24 months of payments.
    
 
     The Reorganization Agreement provides for the termination of the AmeriFed
ESOP whereby all accrued benefits shall be distributed to the accounts of
participants.
 
     Indemnification; Insurance. The Reorganization Agreement provides that NBD
will indemnify the directors and officers of AmeriFed and AmeriFed Bank against
certain liabilities following consummation of the Merger for a period of two (2)
years after the Merger. In addition, the Reorganization Agreement requires the
liability insurance maintained by NBD to be applicable to directors and officers
of AmeriFed and AmeriFed Bank during such period.
 
RESALES OF NBD COMMON STOCK
 
     All shares of NBD Common Stock received by AmeriFed stockholders pursuant
to the Merger will be freely tradeable except that such shares received by
persons who are deemed to be "affiliates" of AmeriFed for the purposes of Rule
145 under the Securities Act may be resold by them only in transactions
permitted by such rule, or as otherwise permitted under the Securities Act. In
the Reorganization Agreement, AmeriFed has agreed to deliver to NBD a letter
identifying all persons who it deems to be "affiliates" for this purpose, and
each such person shall deliver to NBD, 30 days prior to the Effective Date of
Merger, a written agreement that such person shall not offer to sell or
otherwise dispose of any shares of NBD Common Stock issued to such person
pursuant to the Merger in violation of the Securities Act or the regulations
thereunder.
 
STOCK OPTION AGREEMENT
 
     The following description of the Option Agreement is qualified in its
entirety by reference to the Option itself. A COPY OF THE OPTION AGREEMENT WILL
BE PROVIDED WITHOUT CHARGE TO ANY PERSON TO WHOM THIS PROXY STATEMENT-PROSPECTUS
IS DELIVERED UPON WRITTEN REQUEST TO ROBERT BIEDRON, EXECUTIVE VICE PRESIDENT
AND SECRETARY OF AMERIFED, OR DANIEL T. LIS, SENIOR VICE PRESIDENT AND SECRETARY
OF NBD, AT THEIR RESPECTIVE ADDRESSES INDICATED UNDER "AVAILABLE INFORMATION".
 
     At the time of execution of the Agreements, AmeriFed and NBD entered into a
Stock Option Agreement dated as of March 23, 1994, pursuant to which AmeriFed
granted an option to NBD to purchase up to 610,578 shares of AmeriFed Common
Stock, or approximately 19.9% of the then outstanding shares, at a price per
share of $32.75 (the "Option"), exercisable only upon the happening of certain
events that in general would
 
                                       26
<PAGE>   32
 
indicate that a third party is attempting to acquire control of AmeriFed. The
Option is exercisable only if NBD has fully complied with the terms of the
Agreements at the time of exercise. Depending on the number of shares purchased,
the exercise of the Option may be subject to the approval of requisite
government regulatory authorities.
 
     If the conditions to exercise of the Option have been met, the Option may
be exercised by NBD in whole or in part at any time prior to March 31, 1995,
provided that the Option may not be exercised at any time after termination of
the Agreements. NBD has paid $1,000 as cash consideration for the Option. In the
event that NBD exercises the Option, the option fee of $1,000 shall be applied
against the purchase price of the shares.
 
   
     The Option Agreement provides that NBD may exercise the Option only if any
of the following events has occurred: (i) the making, other than by NBD or any
of its subsidiaries, of a tender or exchange offer for 10% or more of the shares
of AmeriFed Common Stock and the persons making such offer have made the
required filings with the Commission and received regulatory approvals from the
proper regulatory authorities; (ii) the acquisition by any person or group of
persons, other than by NBD or any of its subsidiaries, of beneficial ownership,
as defined by the Securities Exchange Act of 1934, as amended, of 10% or more of
the outstanding shares of AmeriFed Common Stock; or (iii) the acceptance by
AmeriFed of any firm proposal, however conditional or future, by any person,
other than NBD or any of its subsidiaries, to: (a) acquire AmeriFed (or any of
its banking subsidiaries) by merger, consolidation, purchase of all or
substantially all of AmeriFed's or such subsidiary's assets or other similar
transaction, or (b) make a tender or exchange offer described in (i) above. At
any time the Option is exercisable upon the occurrence of one of the foregoing
events, AmeriFed, at NBD's request, shall repurchase the Option from NBD at a
price which represents the amount by which the third-party offer exceeds the
Option exercise price.
    
 
   
     The Option provides that in the event the Option is exercised by NBD and
the Agreements are terminated by reason of mutual agreement of the parties or
material breach by NBD, AmeriFed shall have the right to purchase for cash all
of the option shares, provided AmeriFed gives NBD written notice of its
intention to purchase such shares within seven business days after termination
of the Agreements. Further, regardless of the reason for the termination of the
Agreements, if the option shares have been purchased by NBD after an event set
forth in (i) or (iii) of the above paragraph has occurred, and subsequently the
tender or exchange offer or proposal contemplated thereby is terminated, then
AmeriFed shall have the right at the end of six months after such termination
and within seven business days thereafter to repurchase all of the option shares
from NBD. Further, regardless of the reason for the termination of the
Agreements, if the option shares have been purchased by NBD after an event set
forth in (ii) of the above paragraph has occurred, and subsequently a tender or
exchange offer or other proposal to acquire AmeriFed is not consummated by the
acquiring persons within six months after such purchase, then AmeriFed shall
have the right at the end of six months thereafter and within seven business
days thereof to repurchase all of the option shares from NBD. The purchase price
for such shares shall be that paid by NBD for its purchase of such shares plus
interest at the rate equal to the rate publicly announced by NBD Bank, N.A.
(Michigan) from time to time as the "Prime Rate" from the date of purchase to
the date of repurchase.
    
 
APPRAISAL RIGHTS
 
   
     Pursuant to 262(b) of the Delaware General Corporation Law, stockholders of
Delaware corporations do not have the right to object and obtain payment of the
fair value of their shares in business combination transactions if, on the
record date fixed to determine the stockholders entitled to receive notice of
and vote at the meeting at which the corporate action is to be taken, such
shares are registered on a United States securities exchange registered under
the Securities Exchange Act of 1934 or traded on Nasdaq National Market or a
similar market. AmeriFed Common Stock was traded on Nasdaq National Market on
the Record Date and the NBD Common Stock to be issued in the Merger will be
listed on NYSE, and therefore appraisal rights will not be available with
respect to the Merger.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
   
     The following is a discussion of certain federal income tax consequences of
the Merger and the Subsidiary Bank Merger to AmeriFed, AmeriFed Bank and holders
of AmeriFed Common Stock. The discussion is based upon the Code, Treasury
Regulations, Internal Revenue Service (the "Service") rulings, and judicial and
administrative decisions in effect as of the date hereof, all of which are
subject to change at any time, possibly with retroactive effect. This discussion
assumes that AmeriFed Common Stock is held as a "capital asset" within the
meaning of Section 1221 of the Code (i.e., property generally held for
investment). This discussion does not address all of the tax consequences that
may be relevant to a holder of AmeriFed Common Stock in light of his or her
particular circumstances or to holders subject to special rules, such as foreign
persons, financial institutions, tax-exempt organizations or insurance
companies. The opinions of such counsel referred to in this section will be
based on facts existing at the Effective Date of Merger, and in rendering such
opinions, such counsel will require and rely upon representations contained in
certificates of officers of AmeriFed, AmeriFed Bank, as well as NBD, NBD
Illinois and others.
    
 
HOLDERS OF AMERIFED COMMON STOCK SHOULD CONSULT THEIR TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.
 
   
     It is a condition to the obligation of NBD to consummate the Merger that
AmeriFed shall have received an opinion from Muldoon, Murphy & Faucette, counsel
to AmeriFed, substantially to the effect that the Merger will be treated as a
reorganization within the meaning of Section 368(a) of the Code and,
accordingly, for federal income tax purposes, no gain or loss will be recognized
by AmeriFed or AmeriFed Bank as a result of the Merger except, with respect to
the Subsidiary Bank Merger, to the extent AmeriFed or AmeriFed Bank is required
to recognize taxable income due to the recapture of AmeriFed Bank's bad debt
reserves. Additionally, no gain or loss will be recognized by holders of
AmeriFed Common Stock except with respect to any cash received in lieu of
fractional shares. More specifically, AmeriFed has received an opinion of
Muldoon, Murphy & Faucette with respect to the Merger that, for federal income
tax purposes:
    
 
            (i) Assuming that the Merger transaction constitutes a merger under
                the applicable state or federal law, the merger of AmeriFed with
                and into NBD Illinois will constitute a reorganization within
                the meaning of Section 368(a)(1)(A) and Section 368(a)(2)(D) of
                the Code, and AmeriFed, NBD Illinois and NBD will each be a
                "party to a reorganization" within the meaning of Section 368(b)
                of the Code.
 
           (ii) The basis of the assets of AmeriFed to be received by NBD
                Illinois will be the same as the basis of those assets in the
                hands of AmeriFed immediately prior to the Merger.
 
           (iii) The holding period of the assets of AmeriFed to be received by
                 NBD Illinois will include the holding period of those assets in
                 the hands of AmeriFed immediately prior to the Merger.
 
           (iv) No gain or loss will be recognized by NBD Illinois and NBD upon
                receipt of the assets of AmeriFed by NBD Illinois in exchange
                for the consideration provided for in the Merger Agreement and
                the assumption by NBD Illinois of the liabilities of AmeriFed.
 
            (v) NBD Illinois will succeed to and take into account the items of
                AmeriFed described in Section 381(c) of the Code and NBD
                Illinois will be the "acquiring corporation" within the meaning
                of Section 1.381(a)-1(b)(2) of the Treasury Regulations. These
                items will be taken into account by NBD Illinois subject to the
                conditions and limitations specified in Sections 381, 382 and
                383 of the Code and the Treasury Regulations thereunder.
 
           (vi) No gain or loss will be recognized by AmeriFed upon the transfer
                of its assets to NBD Illinois in exchange for the consideration
                provided for in the Merger Agreement and the assumption by NBD
                Illinois of the liabilities of AmeriFed.
 
                                       28
<PAGE>   34
 
           (vii) No gain or loss will be recognized by the shareholders of
                 AmeriFed who receive shares of NBD Common Stock in exchange for
                 all of their shares of AmeriFed Common Stock, except to the
                 extent of any cash received in lieu of a fractional share of
                 NBD Common Stock.
 
          (viii) The basis of NBD Common Stock to be received by shareholders of
                 AmeriFed will, in each instance, be the same as the basis of
                 the shares of AmeriFed Common Stock surrendered in exchange
                 therefor.
 
           (ix) The holding period of the NBD Common Stock received by
                shareholders of AmeriFed will, in each instance, include the
                holding period of the shares of AmeriFed Common Stock
                surrendered in exchange therefor, provided that AmeriFed Common
                Stock was, in each instance, held as a capital asset in the
                hands of the shareholder of AmeriFed on the Effective Date of
                Merger.
 
            (x) The payments of cash in lieu of fractional share interests of
                NBD Common Stock will be treated as having been received as
                distributions in full payment in exchange for the stock redeemed
                as provided in Section 302(a) of the Code.
 
     Based upon the current ruling position of the Service, cash received by a
holder of AmeriFed Common Stock in lieu of a fractional share interest in NBD
Common Stock will be treated as received in exchange for such fractional share
interest, and gain or loss will be recognized for federal income tax purposes
measured by the difference between the amount of cash received and the portion
of the basis of the share of AmeriFed Common Stock allocable to such fractional
share interest. Such gain or loss should be long-term capital gain or loss if
such share of AmeriFed Common Stock has been held for more than one year at the
Effective Date of Merger.
 
     Ordinary income, in an amount equal to the fair market value of NBD Common
Stock received, will be realized by holders of options, whether incentive stock
options or non-qualified stock options, who receive NBD Common Stock in exchange
for their options. The basis of the NBD Common Stock received by holders of
options will be equal to the amount of ordinary income recognized and the
holding period will begin on the exchange date.
 
     Pursuant to the Subsidiary Bank Merger Agreement, AmeriFed Bank will be
merged with and into NBD Bank and, consequently, will no longer be entitled to
use the reserve method for computing and deducting its losses for bad debts. In
addition, as a result of the Subsidiary Bank Merger, the entire amount of
AmeriFed Bank's bad debt reserve, which is currently approximately $23,000,000,
will be required to be included in income currently, or possibly spread over a
period of years.
 
STOCK EXCHANGE LISTING
 
     The NBD Common Stock is listed on the NYSE. NBD has agreed to cause the
shares of the NBD Common Stock to be issued in the Merger to be approved for
listing on the NYSE, subject to official notice of issuance, prior to or at the
Effective Date of Merger. The obligations of the parties to consummate the
Merger are subject to approval for listing by the NYSE of such shares. See
"PROPOSED MERGER -- Conditions to the Merger."
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a purchase and certain adjustments will
have to be made with respect to the acquired assets and liabilities of AmeriFed
based upon estimated fair market values. The actual adjustments will be made on
the basis of appraisals and evaluations as of the date of consummation of the
Merger.

<PAGE>   35
 
                        DESCRIPTION OF NBD CAPITAL STOCK
 
GENERAL
 
   
     Under the Restated Certificate of Incorporation of NBD, as amended (the
"NBD Certificate"), its authorized capital stock consists of 10,000,000 shares
of Preferred Stock, without par value, and 500,000,000 shares of NBD Common
Stock with a par value of $1.00 per share. At October 31, 1994, 155,918,309
shares of NBD Common Stock were outstanding. Although no shares of Preferred
Stock were outstanding at such date, shares of Preferred Stock were reserved for
issuance pursuant to potential NBD exercise of the purchase contracts under the
Preferred Purchase Units as described below under "-- Preferred Stock." In
addition, the NBD Certificate authorizes the issuance of 460,000 shares of
Series A Preferred Stock, all of which were issued in 1987 and redeemed in 1988.
    
 
     The NBD Certificate contains specific provisions with respect to the
election of directors, which include the provision that the Board of Directors
is divided into three classes, each having a number of directors as nearly equal
as possible, and each class being elected for a three-year term, with one class
being elected each year. The NBD Certificate also includes specific provisions
with respect to mergers and other business combinations. In general, these
provisions require that in the case of a proposed merger or other business
combination involving NBD and an interested stockholder (in general defined as
one owning 10% or more of the voting power of the then outstanding NBD capital
stock) the approving vote of the holders of at least a majority of the voting
power of all the shares of voting stock held by persons who are not interested
stockholders or persons affiliated with interested stockholders is required
unless the business combination has been approved by a majority of directors not
affiliated with the interested stockholder or unless certain conditions
regarding minimum price and procedural protections are met with respect to each
class of NBD's then outstanding voting stock. They also require that the NBD
Board of Directors shall not approve a proposal for a business combination or a
tender offer until the Board has evaluated the proposal in light of its effect
on the stockholders and employees of NBD and the communities served by NBD.
These provisions of the NBD Certificate could be used to make more difficult a
change in control of NBD.
 
PREFERRED STOCK
 
     The Board of Directors of NBD is authorized, without further action by the
stockholders of NBD, to issue Preferred Stock, without par value, in one or more
series, from time to time, with such voting powers, full or limited but not to
exceed one vote per share, or without voting powers, and with such designations,
preferences and relative, participating, optional or other special rights, and
qualifications, limitations and restrictions thereof, as may be provided in a
resolution or resolutions adopted by the Board of Directors. The authority of
the Board of Directors includes, but is not limited to, the determination or
fixing of the following with respect to shares of such class or any series
thereof: (i) the number of shares and designation; (ii) the dividend rate and
whether dividends are to be cumulative; (iii) whether shares are to be
redeemable and, if so, the terms and amount of any sinking fund providing for
the purchase or redemption of such shares; (iv) whether shares shall be
convertible and, if so, the terms and provisions applying; (v) what voting
rights are to apply, if any, not to exceed one vote per share; and (vi) what
restrictions are to apply, if any, on the issue or reissue of any additional
Preferred Stock. No Preferred Stock of this class has been issued. If Preferred
Stock of the class were to be issued, it would be preferred to the Common Stock
with respect to dividends and other matters and might have the effect of making
more difficult any change in control of NBD.
 
     On May 11, 1993 NBD issued 6,000,000 Units of which each 7 1/2% Preferred
Purchase Unit consisted of a 30-year subordinated debenture and a purchase
contract requiring the purchase on May 10, 2023 (or earlier at NBD's election)
of NBD 7 1/2% Cumulative Preferred Stock (the "7 1/2% Preferred") at a purchase
price of $25 per share. NBD may redeem any or all of the Units anytime after May
10, 1998, at par, and as a result some or all of the 7 1/2% Preferred may not be
issued by NBD. The 7 1/2% Preferred would rank prior to the NBD Common Stock,
but would have no voting rights except if the Units were in default or the NBD
Certificate was proposed to be amended in a manner adverse to the 7 1/2%
Preferred stockholder. The Preferred Stock which could be issued pursuant to the
purchase contract has been reserved by NBD on its stock records.

COMMON STOCK
 
   
     Dividend Rights. Subject to any prior rights of the Preferred Stock then
outstanding, holders of NBD's Common Stock are entitled to receive such
dividends as are declared by its Board of Directors out of funds legally
available therefor.
    
 
   
     Voting Rights -- Non-Cumulative Voting. Subject to the voting rights, if
any, of the Preferred Stock, all voting rights are vested in the holders of
shares of NBD Common Stock, each share being entitled to one vote.
    
 
   
     The shares of NBD Common Stock have non-cumulative voting rights, which
means that the holders of more than 50% of the shares of NBD Common Stock voting
for the election of directors can elect 100% of the directors standing for
election at any meeting if they choose to do so and, in such event, the holders
of the remaining shares voting for the election of directors will not be able to
elect any person or persons to the Board of Directors at that meeting.
    
 
   
     Liquidation Rights. Subject to the rights of the Preferred Stock, in the
event of liquidation, the holders of the NBD Common Stock will be entitled to
receive pro rata any assets distributable to stockholders in respect of shares
held by them.
    
 
   
     Preemptive Rights. Holders of NBD Common Stock do not have any right to
subscribe to any additional securities which may be issued by NBD. Accordingly,
holders of NBD Common Stock have no statutory right to purchase a proportionate
share of any new NBD Common Stock or other securities issued by NBD.
    
 
   
     Other Matters. The NBD Common Stock does not have any redemption provisions
applicable thereto, and all outstanding shares are fully paid and
non-assessable.
    
 
                 COMPARATIVE RIGHTS OF HOLDERS OF CAPITAL STOCK
                              OF AMERIFED AND NBD
 
     The rights of holders of shares of AmeriFed Common Stock are governed by
AmeriFed's Certificate of Incorporation, By-laws and Delaware law, while the
rights of holders of shares of NBD Common Stock are governed by the NBD
Certificate, NBD's By-Laws and Delaware law. In some respects the rights of
holders of AmeriFed Common Stock and NBD Common Stock are similar. For example,
each holder is entitled to one vote for each share held (although AmeriFed has a
10% voting limitation as discussed subsequently); each is entitled to receive
pro rata any assets distributed to holders of common stock upon liquidation; and
each is subject to the rights of any preferred stock, when issued. Neither has
any preemptive rights to subscribe for or purchase additional shares or
cumulative voting rights in the election of directors.
 
     There are, however, some differences between the rights of holders of
AmeriFed Common Stock and holders of NBD Common Stock. A summary of these
differences is set forth subsequently. This summary, however, does not purport
to be complete and is qualified in its entirety by reference to the respective
Certificate of Incorporation and By-Laws of NBD and AmeriFed and the applicable
provisions of Delaware law.
 
ANTI-TAKEOVER AND SUPERMAJORITY PROVISIONS
 
     Delaware law contains an anti-takeover provision that prevents buyers who
acquire 15% or more of a target company's stock from completing a hostile
takeover for three years. A takeover can, however, be completed if the buyer,
while acquiring this 15% interest, manages to acquire at least 85% of the
outstanding stock. The 85% excludes shares owned by directors who are also
officers and certain shares held under certain employee stock plans. The
takeover can also be completed if it is approved by the target company's board
of directors prior to the date the buyer became a 15% or more stockholder or
after the date the buyer became a 15% or more stockholder if it is approved by
the target company's board of directors and two-thirds of the shares voting at
an annual or special meeting of stockholders, excluding shares held by the
buyer. The anti-takeover provision applies automatically to Delaware
corporations except those corporations with less than 2,000 stockholders of
record or those that do not have voting stock listed on a national securities
exchange or listed for quotation with a registered national securities
association. Such a corporation may, if it
 
                                       31
<PAGE>   37
 
wishes, "opt in" by amending its certificate of incorporation to adopt the
provision. Any corporation may decide to "opt out" of the statute at any time,
by action of its stockholders.
 
     Under AmeriFed's Certificate, an affirmative vote of 80% of the then
outstanding shares of stock of AmeriFed entitled to vote in the election of
directors ("AmeriFed Voting Stock") is required to approve certain business
combination transactions with a beneficial owner of 10% or more of the AmeriFed
Voting Stock when the combination has not been approved by AmeriFed's Board.
 
     The NBD Certificate also contains specific provisions with respect to
mergers and other business combinations. See "DESCRIPTION OF NBD CAPITAL STOCK
- -- General."
 
CAPITALIZATION
 
   
     AmeriFed is authorized to issue 6,000,000 shares of AmeriFed Common Stock,
$.01 par value. At November 1, 1994, there were 3,220,333 shares of AmeriFed
Common Stock outstanding, held of record by approximately 1,610 holders.
    
 
     AmeriFed is authorized to issue 1,500,000 shares of preferred stock, $.01
par value ("AmeriFed Preferred Stock"). The AmeriFed Board is authorized to
provide for the issuance of AmeriFed Preferred Stock in series, to establish
from time to time the number of shares to be included in each such series, and
to fix the designation, powers, preferences and rights of the shares of each
such series and any qualifications, limitations, or restrictions thereof. There
are currently no shares of AmeriFed Preferred Stock outstanding.
 
     For a discussion of the capitalization of NBD, see "DESCRIPTION OF NBD
CAPITAL STOCK" above.
 
BOARD OF DIRECTORS
 
   
     Both the AmeriFed Certificate and NBD Certificate provide for a classified
Board of Directors. The classification of directors could be used to make it
more difficult to change the membership of the Board of Directors since at least
two annual stockholder meetings would be required to effect a change in a
majority of the directors. See "DESCRIPTION OF NBD CAPITAL STOCK -- General."
    
 
     Under the NBD Certificate, NBD's directors may only be removed for cause
and only by a majority vote of stockholders. The AmeriFed Certificate provides
that directors may only be removed for cause and only by the affirmative vote of
holders of not less than 80 percent of the outstanding shares of capital stock
of AmeriFed entitled to vote generally in the election of directors.
 
     Both the AmeriFed By-laws and NBD Certificate contain procedures for
nominations by stockholders of candidates for election as a director. Notices
containing prescribed information on nominations by stockholders of candidates
for election as a director of NBD must be appropriately delivered at least 60
days but not more than 90 days prior to the anniversary date of the immediately
preceding NBD annual meeting of stockholders. The specified written notice for
nominations by stockholders of candidates for an AmeriFed director must be
appropriately delivered generally not less than 90 days prior to the date of the
annual meeting; provided, however, in the event that less than 100 days notice
or prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholders must be received not later than the
close of business on the 10th day following the day on which such notice of the
date of the annual meeting was mailed or such public disclosure was made.
 
ACTION BY STOCKHOLDERS
 
     Both the AmeriFed Certificate and NBD Certificate prohibit stockholder
action by written consent and require that any stockholder action be taken at a
meeting of stockholders. Also, under the Amerifed Certificate and NBD
Certificate, stockholders are not permitted to call a special meeting of
stockholders.

VOTING LIMITATION
 
   
     The AmeriFed Certificate contains a provision limiting the voting rights of
any person who beneficially owns more than 10% of the then-outstanding shares of
AmeriFed Common Stock (the "Limit"). A person who beneficially owns Common Stock
in excess of the limit shall not be entitled, or permitted to any vote in
respect of the shares held in excess of the Limit. The number of votes which may
be cast by any record owner of AmeriFed Common Stock in excess of the Limit
shall be a number equal to the total number of votes which a single record owner
of all AmeriFed Common Stock owned by such person would be entitled to cast,
multiplied by a fraction, the numerator of which is the number of shares of such
class or series beneficially owned by such person and owned of record by such
record owner and the denominator of which is the total number of shares of
AmeriFed Common Stock beneficially owned by such person owning shares in excess
of the Limit. The AmeriFed Certificate authorizes the Board of Directors (i) to
make all determinations necessary to implement and apply the Limit, including
determining whether persons or entities are acting in concert, and (ii) to
determine that a person who is reasonably believed to beneficially own stock in
excess of the Limit, be required to supply information to AmeriFed to enable the
Board of Directors to implement and apply the Limit.
    
 
     There is no comparable limitation in NBD's Certificate or Bylaws.
 
AMENDMENT OR REPEAL OF CERTAIN PROVISIONS
 
     The provisions of AmeriFed's Certificate described herein may be amended
only by the affirmative vote of at least 80 percent of the outstanding shares
entitled to vote on the proposed amendment. The AmeriFed By-laws may be amended
by a majority of the AmeriFed Board or by the affirmative vote of at least 80
percent of the outstanding shares entitled to vote generally in the election of
directors.
 
     NBD's Certificate contains similar stockholder vote for the amendment of
the provisions discussed under "-- Board of Directors," "Action by Stockholders"
and "DESCRIPTION OF NBD CAPITAL STOCK -- General." NBD By-laws, however, may
only be amended by a majority of the NBD Board.
 
                     RELATIONSHIP WITH INDEPENDENT AUDITORS
 
     Deloitte & Touche LLP is currently serving as the independent auditors for
each of NBD and AmeriFed. It is expected that a representative of Deloitte &
Touche LLP will be present at the Special Meeting of Stockholders to respond to
appropriate questions and such representative will have an opportunity to make a
statement if he or she so desires.
 
                                    EXPERTS
 
     The consolidated financial statements of NBD incorporated in this Proxy
Statement-Prospectus by reference from NBD's Annual Report on Form 10-K for the
year ended December 31, 1993, have been audited by Deloitte & Touche LLP, as
stated in their report, which is incorporated herein by reference. The
consolidated financial statements give retroactive effect to the mergers of NBD
and Summcorp, and of NBD and INB Financial Corporation, each of which has been
accounted for as a pooling of interests. Deloitte & Touche LLP did not audit the
statements of income, stockholders' equity, and cash flows of Summcorp and INB
Financial Corporation for the year ended December 31, 1991. Those financial
statements have been audited by KPMG Peat Marwick LLP and Ernst & Young LLP,
respectively, as stated in their reports incorporated herein by reference. The
report of Deloitte & Touche LLP, insofar as it relates to the amounts included
for Summcorp and INB Financial Corporation for 1991, is based solely on the
reports of such other auditors. Such consolidated financial statements of NBD
are incorporated herein by reference in reliance upon the reports of such firms
given upon their authority as experts in accounting and auditing. All of the
foregoing firms are independent auditors.
 
   
     The consolidated financial statements of AmeriFed incorporated in this
Proxy Statement-Prospectus by reference from AmeriFed's Annual Report on Form
10-K for the year ended September 30, 1993, have been

the report of such firm given upon their authority as experts in accounting and
auditing.
 
                                 LEGAL MATTERS
 
     Legal matters in connection with the Merger will be passed upon for NBD by
Daniel T. Lis, internal legal counsel to NBD. Mr. Lis is a Senior Vice President
and Secretary of NBD, and is also a stockholder of NBD and a holder of options
to purchase shares of NBD. Legal matters in connection with the Merger will be
passed upon for AmeriFed by Muldoon, Murphy & Faucette, Washington, D.C.,
including an opinion concerning certain federal income tax consequences of the
Merger.
 
                                 OTHER MATTERS
 
     The AmeriFed Board of Directors, as of the date hereof, is not aware of any
business to be presented at the Special Meeting, other than that referred to in
the Notice of Special Meeting of Stockholders and discussed herein. IF ANY

PROXIES WILL HAVE AUTHORITY TO VOTE THE SHARES REPRESENTED BY PROXIES IN
ACCORDANCE WITH THEIR DISCRETION AND JUDGMENT AS TO THE BEST INTERESTS OF
AMERIFED.

     WHEREAS, Bancorp Subsidiary is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware. As of the

Company Common Stock are reserved for issuance under outstanding stock options,
and 161,000 shares of Company Common Stock are held in its treasury; and
1,500,000 shares of Preferred Stock, $.01 par value, of which no shares are

     WHEREAS, Bancorp Subsidiary, the Company and Bancorp have entered into an

Agreement;
 
     WHEREAS, the respective Boards of Directors of the Company, Bancorp and

and the Boards of Directors of the Company and Bancorp Subsidiary have directed
that this Merger Agreement be submitted to their respective stockholders for

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements herein contained, the parties hereto hereby covenant and agree as
follows:
 
                                   ARTICLE I
 
     1.1 MERGER OF THE COMPANY INTO BANCORP SUBSIDIARY. The Company shall be
merged into Bancorp Subsidiary on the date specified therefor in a Certificate
of Merger filed by Bancorp Subsidiary in accordance with the General Corporation
Law of the State of Delaware (the close of business on the date so specified
being referred to herein as the "Effective Date of Merger"). The separate

shall be the surviving corporation. Bancorp Subsidiary is herein sometimes
referred to as the "Surviving Corporation".
 
                                       A-1
<PAGE>   41
 
     1.2 EFFECT OF THE MERGER. From and after the Effective Date of Merger:
 
          (a) The separate existence of the Constituent Corporations (except the
     Surviving Corporation) shall cease and be merged into one, the Surviving
     Corporation, which shall possess all of the rights, privileges, immunities,
     powers and franchises of a public as well as of a private nature, and shall
     be subject to all of the restrictions, disabilities and duties, of each of
     the Constituent Corporations so merged; and all and singular rights,
     privileges, immunities, powers and franchises of each of the Constituent
     Corporations, and all property, real, personal and mixed, and all debts due
     to either of the Constituent Corporations on whatever account, including
     subscriptions to shares, and all other things in action or belonging to
     each of the Constituent Corporations shall be vested in the Surviving
     Corporation resulting from the Merger; and all property, rights,
     privileges, immunities, powers and franchises, and all and every interest,
     shall be thereafter as effectually the property of the Surviving
     Corporation as they were of the Constituent Corporations and the title to
     any real estate, vested by deed or otherwise, in either of the Constituent
     Corporations, shall not revert or be in any way impaired by reason of the
     Merger.
 
          (b) All rights of creditors and all liens upon any property of either
     of the Constituent Corporations shall be preserved unimpaired and all
     debts, liabilities and duties of the respective Constituent Corporations
     shall thenceforth attach to the Surviving Corporation and may be enforced
     against the Surviving Corporation to the same extent as if said debts,
     liabilities and duties had been incurred or contracted by it.
 
          (c) Any action or proceeding, whether civil, criminal or
     administrative, pending by or against either Constituent Corporation shall
     be prosecuted as if the Merger had not taken place, or the Surviving
     Corporation may be substituted as a party in such action or proceeding in
     place of the Constituent Corporation.
 
     1.3 ADDITIONAL ACTIONS. If, at any time after the Effective Date of Merger,
the Surviving Corporation shall consider or be advised that any further
assignments or assurances in law or any other acts are necessary or desirable to
(a) vest, perfect or confirm, of record or otherwise, in the Surviving
Corporation its rights, title or interest in, to or under any of the rights,
properties or assets of the Company acquired or to be acquired by the Surviving
Corporation as a result of, or in connection with, the Merger, or (b) otherwise
carry out the purposes of this Merger Agreement, the Company and its proper
officers and directors shall be deemed to have granted to the Surviving
Corporation an irrevocable power of attorney to execute and deliver all such
proper deeds, assignments and assurances in law and to do all acts necessary or
proper to vest, perfect or confirm title to and possession of such rights,
properties or assets in the Surviving Corporation and otherwise to carry out the
purposes of this Merger Agreement; and the proper officers and directors of the
Surviving Corporation are fully authorized in the name of the Company or
otherwise to take any and all such action.
 
                                   ARTICLE II
 
     2.1 NAME. The name of the Surviving Corporation shall be NBD Illinois, Inc.
 
     2.2 CERTIFICATE OF INCORPORATION. From and after the Effective Date of
Merger, the Certificate of Incorporation of Bancorp Subsidiary shall be the
Certificate of Incorporation of the Surviving Corporation until duly amended in
accordance with law.
 
     2.3 BYLAWS. The Bylaws of Bancorp Subsidiary, as in effect immediately
prior to the Effective Date of Merger, shall be the Bylaws of the Surviving
Corporation until duly amended in accordance with law.
 
     2.4 DIRECTORS AND OFFICERS. The directors and officers of the Surviving
Corporation shall be the directors and officers of Bancorp Subsidiary
immediately prior to the Effective Date of Merger.

                                  ARTICLE III
 
     3.1 MANNER AND BASIS OF CONVERTING SHARES. At the Effective Date of Merger:
 
          (a) Each share of Bancorp Common Stock and of Bancorp Subsidiary
     Common Stock which is issued and outstanding immediately prior to the
     Effective Date of Merger shall continue to be outstanding without any
     change therein.
 
          (b) All shares of Company Common Stock held in the treasury of the
     Company and all shares of Company Common Stock held by Bancorp or Bancorp
     Subsidiary immediately prior to the Effective Date of Merger shall be
     cancelled, and no Bancorp Common Stock, cash or other consideration shall
     be issuable or exchangeable with respect thereto.
 
          (c) To the extent that there may exist rights of appraisal with
     respect to the Merger, each outstanding share of Company Common Stock as to
     which appraisal is demanded in accordance with the procedures of the
     General Corporation Law of the State of Delaware prior to the vote of the
     Company's stockholders on the Merger and not withdrawn shall be accorded
     the rights provided by such Law and shall not be converted into or
     represent a right to receive shares of Bancorp Common Stock hereunder
     unless and until the holder shall have failed to perfect or shall have
     effectively withdrawn or lost his or her right to appraisal of and payment
     for his or her shares of Company Common Stock.
 
          (d) Subject to sub-paragraphs (b) and (c) preceding, each share of
     Company Common Stock which is outstanding immediately prior to the
     Effective Date of Merger shall be converted without any action on the part
     of the holder thereof into and be exchangeable for the number of shares of
     Bancorp Common Stock (rounded to the nearest thousandth of a share) equal
     to a fraction, the numerator of which shall be equal to $45.00, and the
     denominator of which shall be equal to the average closing price per share
     of Bancorp Common Stock as reported on the New York Stock Exchange
     Composite Tape for the five trading days ending on the fifth trading day
     prior to the Effective Date of Merger, subject to the payment of cash in
     lieu of fractional shares in accordance with Section 3.4 hereof.
 
The shares of Bancorp Common Stock to be issued in accordance with this Merger
Agreement may be authorized but unissued shares or treasury shares; provided
that Bancorp may not purchase any shares of its Common Stock in the 30-day
period prior to the Effective Date of Merger; and provided further that
repurchases of Common Stock by Bancorp shall comply with the rules and
regulations of the Securities and Exchange Commission, the New York Stock
Exchange and all applicable regulatory authorities.
 
     3.2 CESSATION OF STOCKHOLDER STATUS. Holders of certificates which
represent shares of Company Common Stock outstanding immediately prior to the
Effective Date of Merger (hereinafter called "Old Certificates" when referring
to the Company) shall cease to be, and shall have no rights as, stockholders of
the Company.
 
     3.3 SURRENDER OF OLD CERTIFICATES. After the Effective Date of Merger, Old
Certificates shall be exchangeable, subject to Section 3.4 hereof, by the
holders thereof in the manner provided in the transmittal materials described
below for new certificates for the number of shares of Bancorp Common Stock to
which such holders shall be entitled.
 
     As promptly as practicable after the completion of all requisite actions
and the receipt of the final banking authority regulatory approval required for
the Merger, Bancorp shall send or cause to be sent to each former stockholder of
record of Company Common Stock transmittal materials for use in exchanging his
or her Old Certificates for certificates representing Bancorp Common Stock. The
letter of transmittal will contain instructions with respect to the surrender of
Old Certificates.
 
     Whenever a dividend is declared by Bancorp on the Bancorp Common Stock
after the Effective Date of Merger, the declaration shall include dividends on
all shares issuable hereunder, but no former stockholder of the Company will be
deemed to be a record owner nor be entitled to receive his or her distribution
of such dividends until physical exchange of his or her Old Certificates shall
have been effected. Upon physical exchange of his or her Old Certificates, any
such person shall be entitled to receive from Bancorp an amount equal to all
such dividends (without interest thereon and less the amount of taxes, if any,
which may have been
 
                                       A-3
<PAGE>   43
 
imposed or paid thereon) declared, and for which the payment has occurred, on
the shares represented thereby.
 
     On or after the Effective Date of Merger there shall be no transfers on the
stock transfer books of the Company or Bancorp of the shares of Company Common
Stock which were issued and outstanding immediately prior to the Effective Date
of Merger. If, after the Effective Date of Merger, Old Certificates are properly
presented to Bancorp, they shall be cancelled and exchanged for certificates
representing shares of Bancorp Common Stock as herein provided.
 
     3.4 CASH IN LIEU OF FRACTIONAL SHARES. Each holder of Old Certificates who
would otherwise have been entitled to receive a fraction of a share of Bancorp
Common Stock (after taking into account all shares of the Company Common Stock
represented by the Old Certificates then delivered by such holder) shall
receive, in lieu thereof, an amount of cash (without interest) determined by

reverse split, split-up, combination, exchange of shares or readjustment, or a
stock dividend thereon shall be declared with a record date within said period,
the number of shares of Bancorp Common Stock into which shares of Company Common
Stock are to be converted shall be correspondingly adjusted.

                      [THE CHICAGO CORPORATION LETTERHEAD]
 
   
October 24, 1994
    
 
Board of Directors
AmeriFed Financial Corp.
120 Scott Street
Joliet, Illinois 60431
 
Members of the Board:
 
     You have requested our opinion as to the fairness of the merger
consideration (the "Merger Consideration"), from a financial point of view, to
the shareholders of AmeriFed Financial Corp. ("AmeriFed") with respect to the
proposed merger of AmeriFed with and into NBD Bancorp, Inc. ("NBD"). AmeriFed
has entered into an Agreement and Plan of Reorganization and a related Agreement
and Plan of Merger (collectively the "Agreements"), both dated March 23, 1994,
between NBD, NBD Illinois, Inc. ("NBD Illinois") and AmeriFed. As is set forth
in the Agreements, each outstanding share of common stock of AmeriFed will be
converted into and be exchangeable for the number of shares of Common Stock,
$1.00 par value per share, of NBD equal to a fraction, the numerator of which
shall be equal to $45.00 and the denominator of which shall be equal to the
average closing price per share of Common Stock of NBD as reported on the New
York Stock Exchange Composite Tape for the five trading days ending on the fifth
trading day prior to the Effective Date of Merger.
 
     During the course of our engagement, we have, among other things:
 
   
          1) reviewed the Agreements, the audited financial statements for
             AmeriFed for the three fiscal years ended September 30, 1993 and
             for NBD for the three fiscal years ended December 31, 1993, and the
             unaudited financial statements for AmeriFed for the year ended
             September 30, 1994 and for NBD for the nine months ended September
             30, 1994 as provided to us, as well as other internally generated
             AmeriFed reports relating to asset/liability management, asset
             quality and so forth;
    
 
   
          2) reviewed and analyzed other material bearing upon the financial and
             operating condition of NBD and AmeriFed and material prepared in
             connection with the proposed transaction;
    
 
          3) reviewed the operating characteristics of certain other financial
             institutions deemed relevant to the contemplated transaction;
 
          4) reviewed the nature and terms of recent sale and merger
             transactions involving banks, thrifts, bank and thrift holding
             companies and other financial institutions that we consider
             relevant;
 
                              [KEY LETTER ADDRESS]
<PAGE>   46
 
          5) reviewed historical and current market data for NBD and AmeriFed
             common stock;
 
          6) reviewed financial and other information provided to us by the
             managements' of NBD and AmeriFed;
 
          7) conducted meetings with members of the senior management of NBD and
             AmeriFed for the purpose of reviewing the future prospects of NBD
             and AmeriFed;
 
   
          8) reviewed certain information including forecasts pertaining to
             prospective cost savings and revenue enhancements relative to the
             proposed transactions; and
    
 
   
          9) evaluated the pro forma ownership of NBD common stock by AmeriFed
             shareholders, relative to the pro forma contribution of AmeriFed's
             assets, liabilities, equity and earnings to the pro forma company.
    
 
     The Chicago Corporation, as part of its investment banking business, is
continually engaged in the valuation of banks and bank holding companies and
thrifts and thrift holding companies in connection with mergers and acquisitions
as well as initial and secondary offerings of securities as well as valuations
for other purposes. The Chicago Corporation is a member of all principal U.S.
Securities exchanges and in the conduct of our broker-dealer activities may from
time to time purchase securities from, and sell securities to, AmeriFed and NBD
and as a market maker buy or sell the equity securities of AmeriFed for our own
account and for the accounts of customers. In rendering this fairness opinion we
have acted exclusively on behalf of the Board of Directors of AmeriFed and will
receive a fee from AmeriFed for our services.
 
     In rendering this opinion, we have relied upon, without independent
verification, the accuracy and completeness of the financial and other
information and representations provided to us by NBD and AmeriFed. We have
relied upon the management of AmeriFed and NBD as to the reasonableness and
achievability of the financial forecasts and projections (and the assumptions
and basis therefore) provided to us, and have assumed that such forecasts and
projections are the best available estimates of management.
 
     Based on the foregoing and our experience as investment bankers, we are of
the opinion that, as of the date hereof, the Merger Consideration to be paid to
the shareholders of AmeriFed as described in the Agreements, is fair from a
financial point of view.
 
                                        Sincerely,
 
   
                                        [SIG]
    
 
                                        THE CHICAGO CORPORATION

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Article Eighth of the Registrant's Restated Certificate of Incorporation,
as amended, provides for indemnification of directors and officers. The
provision provides that any person shall be indemnified and reimbursed by the
Registrant for expenses and liabilities imposed upon the person in connection
with any action, suit or proceeding, civil or criminal, or threat thereof, in
which the person may be involved by reason of the person being or having been a
director, officer, employee or agent of the Registrant, or of any corporation or
organization which the person served in any capacity at the request of the
Registrant, if the person acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
Registrant and, with respect to any criminal action or proceeding, had no
reasonable cause to believe the person's conduct was unlawful. Provided,
however, that no indemnification shall be made in respect of any matter as to
which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of the person's duty to the Registrant unless the
Court of Chancery of Delaware or the court in which such action or suit was
brought shall determine upon application that such person is fairly and
reasonably entitled to indemnity.
 
     The directors and officers of the Registrant are covered by an insurance
policy, indemnifying them against certain civil liabilities, including
liabilities under the federal securities laws, which might be incurred by them
in such capacity.

ITEM 22. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in this Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered herein and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders of NBD and AmeriFed, that is
incorporated by reference in the prospectus and furnished pursuant to and
meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities
Exchange Act of 1934; and, where interim financial information required to be
presented by Article 3 of Regulation S-X are not set forth in the prospectus, to
deliver, or cause to be delivered to each person to whom the prospectus is sent
or given, the latest quarterly report of NBD and AmeriFed, that is specifically
incorporated by reference in the prospectus to provide such interim financial
information.
 
     The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
Registrant undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called by the other Items of the applicable form.
 
     The Registrant undertakes that every prospectus (i) that is filed pursuant
to the immediately preceding paragraph, or (ii) that purports to meet the
requirement of Section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415 will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 20, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
     The undersigned Registrant hereby undertakes to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement: (i) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any
facts or events arising
 
                                      II-2
<PAGE>   49
 
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represents a fundamental change in the information set forth in this
Registration Statement; and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in this Registration
Statement.
 
     The Registrant further undertakes: (i) that, for the purpose of determining
any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof, and (ii) to remove
from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
